Cervical cancer incidence in the US-affiliated Pacific Islands
Gopalani SV , Qin J , Baksa J , Thompson TD , Saraiya M , Senkomago V , Pordell P , Jeong Y , Palafox NA , Reichhardt M , Buenconsejo-Lum LE . JAMA Oncol 2024 IMPORTANCE: The World Health Organization has called for eliminating cervical cancer as a public health problem. Accurate and up-to-date estimates of population-based cervical cancer incidence are essential for monitoring progress toward elimination and informing local cancer control strategies, but these estimates are lacking for the US-Affiliated Pacific Islands (USAPI). OBJECTIVE: To calculate age-standardized incidence rates for cervical cancer in the 6 USAPI and compare these rates with rates in the US (50 states and the District of Columbia). DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used population-based data from the Pacific Regional Central Cancer Registry for women aged 20 years or older who were diagnosed with invasive cervical cancer from January 1, 2007, to December 31, 2020. The registry comprises data on all cervical cancers from the USAPI, which include 3 US territories (American Samoa, Commonwealth of the Northern Mariana Islands, and Guam) and 3 freely associated states (Federated States of Micronesia [FSM], Republic of the Marshall Islands [RMI], and Republic of Palau). Data were analyzed from July 10, 2023, to November 28, 2023. MAIN OUTCOMES AND MEASURES: The main outcome was age-standardized cervical cancer incidence rates, stratified by age, stage, and histologic code for the USAPI using population estimates from 3 different sources (US Census Bureau International Database, United Nations Population Division, and Pacific Data Hub). Rate ratios were calculated to compare incidence rates between the USAPI and the US. RESULTS: From 2007 to 2020, 409 cases of cervical cancer were diagnosed in the USAPI (median age at diagnosis, 46.0 years [25th-75th percentile, 39.0-55.0 years]), with an age-standardized incidence rate ranging from 21.7 (95% CI, 19.6-23.9) to 22.1 (95% CI, 20.0-24.4) per 100 000 women, depending on the population estimate. Incidence rates were highest in RMI, ranging from 58.1 (95% CI, 48.0-69.7) to 83.4 (95% CI, 68.3-101.0) per 100 000 women, followed by FSM, ranging from 28.7 (95% CI, 23.4-34.9) to 29.8 (95% CI, 24.3-36.3) per 100 000 women. Compared with the US, incidence rates were highest in RMI (rate ratio, 5.7 [95% CI, 4.7-6.8] to 8.2 [95% CI, 6.7-9.9]) and FSM (rate ratio; 2.8; 95% CI, 2.3-3.4). Of all cases in the USAPI, 213 (68.2%) were diagnosed at a late stage. CONCLUSIONS AND RELEVANCE: In this cross-sectional study, cervical cancer remained a major public health issue in some USAPI, with RMI reporting the highest incidence rates. The findings suggest that improvements in human papillomavirus vaccination and cancer screening coverage through efforts tailored to the unique geographic, sociocultural, economic, and health care landscape of the USAPI may reduce the burden of cervical cancer. |
Incidence and survival of pediatric and adult hepatocellular carcinoma, United States, 2001-2020
Arnett A , Siegel DA , Dai S , Thompson TD , Foster J , di Pierro EJ , Momin B , Lupo PJ , Heczey A . Cancer Epidemiol 2024 92 102610 BACKGROUND: Hepatocellular carcinoma accounts for approximately 80 % of liver neoplasms. Globally, hepatocellular carcinoma ranks as the third most lethal cancer, with the number of deaths expected to further increase by 2040. In adults, disparities in incidence and survival are well described while pediatric epidemiology is not well characterized. We describe incidence and survival for pediatric (ages 0-19 years) hepatocellular carcinoma cases and compare these measures to adults (ages ≥ 20 years) diagnosed with hepatocellular carcinoma. METHODS: We assessed incidence data from the US Cancer Statistics database during 2003-2020 and 5-year survival from the National Program of Cancer Registries during 2001-2019. Incidence trends were determined by annual percent change (APC) and average APC (AAPC) using joinpoint regression. Five-year survival was evaluated by relative survival, and all-cause survival was estimated using multivariate Cox modeling. Corresponding 95 % confidence intervals (CI) were calculated for all analyses. RESULTS: Incidence rate per 100,000 persons was 0.056 (95 %CI:0.052-0.060) for pediatric cases and 7.793 (7.767-7.819) for adults. Incidence was stable in the pediatric population (0.3 AAPC, - 1.1 to 1.7). In contrast, after periods of increase, incidence declined in adults after 2015 (-1.5 APC). Relative survival increased over time for both pediatric and adult ages and was higher for children and adolescents (46.4 %, 95 %CI:42.4-50.3) than adults (20.7 %, 95 %CI:20.5-20.9). Regression modeling showed that non-Hispanic Black race and ethnicity was associated with higher risk of death in children and adolescents (1.48, 95 %CI:1.07-2.05) and adults (1.11, 95 %CI:1.09-1.12) compared to non-Hispanic white race and ethnicity. CONCLUSIONS: Between 2003 and 2020 in the United States, pediatric incidence was stable while incidence in adults began to decline after 2015. Survival was higher across all stages for children and adolescents compared to adults. Non-Hispanic Black race and ethnicity showed a higher risk of death for both age groups. Further studies could explore the factors that influence these outcome disparities. |
Breast cancer incidence and stage at diagnosis in the six US-Affiliated Pacific Islands
Gopalani SV , Qin J , Baksa J , Thompson TD , Senkomago V , Pordell P , Jeong Y , Reichhardt M , Palafox N , Buenconsejo-Lum L . Cancer Epidemiol 2024 92 102611 BACKGROUND: Breast cancer is the most common cancer diagnosed among women globally and in the United States (US); however, its incidence in the six US-Affiliated Pacific Islands (USAPI) remains less characterized. METHODS: We analyzed data from a population-based cancer registry using different population estimates to calculate incidence rates for breast cancer among women aged >20 years in the USAPI. Rate ratios and 95 % confidence intervals (CI) were calculated to compare incidence rates between the USAPI and the US (50 states and the District of Columbia). RESULTS: From 2007-2020, 1118 new cases of breast cancer were diagnosed in the USAPI, with 66.3 % (n = 741) of cases reported in Guam. Age-standardized incidence rates ranged from 66.4 to 68.7 per 100,000 women in USAPI and 101.1-110.5 per 100,000 women in Guam. Compared to the US, incidence rates were lower in USAPI, with rate ratios ranging from 0.38 (95 % CI: 0.36, 0.40) to 0.39 (95 % CI: 0.37, 0.42). The proportion of late-stage cancer was significantly higher in the USAPI (48.7 %) than in the US (34.0 %), particularly in the Federated States of Micronesia (78.7 %) and Palau (73.1 %). CONCLUSIONS: Breast cancer incidence rates were lower in the USAPI than in the US; however, late-stage diagnoses were disproportionately higher. Low incidence and late-stage cancers may signal challenges in screening, cancer surveillance, and health care access and resources. Expanding access to timely breast cancer screening, diagnosis, and treatment could reduce the proportion of late-stage cancers and improve survival in the USAPI. |
Scrotal cancer incidence rates and trends-United States, 1999-2020
Mix JM , Gopalani SV , Miller M , Saraiya M , Darragh TM , Lynch CF , Thompson TD , Senkomago V , Greek A , Tucker TC , Unger ER . Urology 2024 OBJECTIVE: To examine population-level scrotal cancer incidence rates and trends among adult men in the United States. METHODS: Data from the United States Cancer Statistics, covering approximately 96% of the United States population, were analyzed to calculate age-standardized incidence rates of scrotal cancer among men aged 18 years and older from 1999 to 2020. Trends in incidence rates were evaluated by age, race and ethnicity, Census region, and histology using joinpoint regression. RESULTS: Overall, 4669 men were diagnosed with scrotal cancer (0.20 per 100,000). Incidence rates were highest among men aged 70 years and older (0.82 per 100,000). Rates were higher among non-Hispanic Asian or Pacific Islander men (0.31 per 100,000) compared to other race and ethnicity groups. The most common histologic subtypes were squamous cell carcinoma (35.9%), extramammary Paget disease (20.8%), and sarcoma (20.5%). Incidence rates decreased by 2.9% per year from 1999 to 2019 for non-Hispanic Asian or Pacific Islander men, decreased by 8.1% per year from 1999 to 2006 for basal cell carcinomas, and increased by 1.8% per year from 1999 to 2019 for extramammary Paget disease; otherwise, rates remained stable for all other variables examined. CONCLUSION: While scrotal cancer incidence rates were higher than previously reported, rates were still low and stable over time. |
Incidence and survival of pediatric and adult hepatocellular carcinoma, United States, 2001-2020
Arnett A , Siegel DA , Dai S , Thompson TD , Foster J , di Pierro EJ , Momin B , Lupo PJ , Heczey A . medRxiv 2024 IMPORTANCE: Hepatocellular carcinoma accounts for approximately 80% of liver neoplasms. Globally, hepatocellular carcinoma ranks as the third most lethal cancer, with the number of deaths expected to further increase by 2040. In adults, disparities in incidence and survival are well described while pediatric epidemiology is not well characterized. OBJECTIVE: To describe incidence and survival for pediatric (ages 0-19 years) hepatocellular carcinoma cases and compare these measures to adults (ages ≥20 years) diagnosed with hepatocellular carcinoma. We evaluated demographic factors and clinical characteristics that influence incidence and outcomes. DESIGN: Population-based cohort study. SETTING: Incidence data from the US Cancer Statistics database from 2003 to 2020 and 5-year relative survival from the National Program of Cancer Registries from 2001 to 2019, covering 97% and 83% of the US population, respectively. PARTICIPANTS: 355,349 US Cancer Statistics and 257,406 the National Program of Cancer Registries patients were identified using ICD-O-3 C22.0 and 8170-5 codes. MAIN OUTCOMES AND MEASURES: Incidence annual percent change (APC) and average APC (AAPC) using joinpoint regression. Five-year relative survival. All-cause survival estimated using multivariate Cox modeling. Corresponding 95% confidence intervals (CI) were calculated. RESULTS: Incidence rate per 100,000 persons was 0.056 (95%CI:0.052-0.060) for pediatric cases and 7.793 (7.767-7.819) for adults. Incidence was stable in the pediatric population (0.3 AAPC, -1.1-1.7). In contrast, after periods of increase, incidence declined in adults after 2015 (-1.5 APC). Relative survival increased over time for both pediatric and adult ages and was higher for children and adolescents (46.4%, 95%CI:42.4-50.3) than adults (20.7%, 95%CI:20.5-20.9) overall and when stratified by stage. Regression modeling showed that non-Hispanic Black race and ethnicity was associated with higher risk of death in children and adolescents (1.48, 95%CI:1.07-2.05) and adults (1.11, 95%CI:1.09-1.12) compared to non-Hispanic white race and ethnicity. CONCLUSIONS AND RELEVANCE: Between 2003 and 2020 in the United States, pediatric incidence was stable while incidence in adults began to decline after 2015. Survival was higher across all stages for children and adolescents compared to adults. Non-Hispanic Black race and ethnicity showed a higher risk of death for both age groups. Further studies could explore the factors that influence these outcome disparities. |
The impact of adjusting for hysterectomy prevalence on cervical cancer incidence rates and trends among women aged 30 years and older - United States, 2001-2019
Gopalani SV , Sawaya GF , Rositch AF , Dasari S , Thompson TD , Mix JM , Saraiya M . Am J Epidemiol 2024 Hysterectomy protects against cervical cancer when the cervix is removed. However, measures of cervical cancer incidence often fail to exclude women with a hysterectomy from the population at risk denominator, underestimating and distorting disease burden. In this study, we estimated hysterectomy prevalence from the Behavioral Risk Factor Surveillance System surveys to remove the women who were not at risk of cervical cancer from the denominator and combined these estimates with the United States Cancer Statistics data. From these data, we calculated age-specific and age-standardized incidence rates for women aged >30 years from 2001-2019, adjusted for hysterectomy prevalence. We calculated the difference between unadjusted and adjusted incidence rates and examined trends by histology, age, race and ethnicity, and geographic region using Joinpoint regression. The hysterectomy-adjusted cervical cancer incidence rate from 2001-2019 was 16.7 per 100,000 women-34.6% higher than the unadjusted rate. After adjustment, incidence rates were higher by approximately 55% among Black women, 56% among those living in the East South Central division, and 90% among women aged 70-79 and >80 years. These findings underscore the importance of adjusting for hysterectomy prevalence to avoid underestimating cervical cancer incidence rates and masking disparities by age, race, and geographic region. |
Human papillomavirus detection in scrotal squamous cell carcinoma: Case series from a population-based cancer registry
Mix JM , Miller MJ , Querec TD , Darragh TM , Saraiya M , Gopalani SV , Lynch CF , Thompson TD , Greek A , Tucker TC , Peters ES , Unger ER . J Registry Manag 2023 50 (4) 116-121 ![]() INTRODUCTION: Scrotal squamous cell carcinomas (SCCs) are rare malignancies that are not considered to be associated with the human papillomavirus (HPV) by the International Agency for Research on Cancer. However, recent studies have detected HPV in these cancers. We sought to determine the presence of HPV types among scrotal cancer cases identified through population-based cancer registries. METHODS: Primary scrotal SCCs diagnosed from 2014 to 2015 were identified, and tissue sections from formalin-fixed, paraffin-embedded tissue blocks were obtained for laboratory testing. A pathology review was performed to confirm morphology. HPV testing was performed using L1 consensus polymerase chain reaction analysis. Immunohistochemistry was used to evaluate p16INK4a (p16) expression. RESULTS: Five cases of scrotal SCC were identified from 1 cancer registry. Age at diagnosis ranged from 34 to 75 years (median, 56 years). Four cases were non-Hispanic White, and 1 was non-Hispanic Black. The morphologic subtype of 4 cases was keratinizing (usual), and 1 case was verrucous (warty) histologic subtype. Two of the usual cases of SCC were HPV-negative and p16-negative, and 2 were positive for HPV16 and p16. The verrucous (warty) SCC subtype case was HPV6-positive and p16-negative. CONCLUSIONS: The presence of HPV16 and p16 overexpression in the examined tissue specimens lends additional support for the role of HPV in the etiology of scrotal SCC. |
Up-to-date breast, cervical, and colorectal cancer screening test use in the United States, 2021
Sabatino SA , Thompson TD , White MC , Villarroel MA , Shapiro JA , Croswell JM , Richardson LC . Prev Chronic Dis 2023 20 E94 INTRODUCTION: We examined national estimates of breast, cervical, and colorectal cancer (CRC) screening test use and compared them with Healthy People 2030 national targets. Test use in 2021 was compared with prepandemic estimates. METHODS: In 2022, we used 2021 National Health Interview Survey (NHIS) data to estimate proportions of adults up to date with US Preventive Services Task Force recommendations for breast (women aged 50-74 y), cervical (women aged 21-65 y), and CRC screening (adults aged 50-75 y) across sociodemographic and health care access variables. We compared age-standardized estimates from the 2021 and 2019 NHIS. RESULTS: Percentages of adults up to date in 2021 were 75.7% (95% CI, 74.4%-76.9%), 75.2% (95% CI, 73.9%-76.4%), and 72.2% (95% CI, 71.2%-73.2%) for breast, cervical, and CRC screening, respectively. Estimates were below 50% among those without a wellness check in 3 years (all screening types), among those without a usual source of care or insurance (aged <65 y) (breast and CRC screening), and among those residing in the US for less than 10 years (CRC screening). Percentages of adults who were up to date with breast and cervical cancer screening and colonoscopy were similar in 2019 and 2021. Fecal occult blood/fecal immunochemical test (FOBT/FIT) use was modestly higher in 2021 (P < .001). CONCLUSIONS: In 2021, approximately 1 in 4 adults of screening age were not up to date with breast, cervical, and CRC screening recommendations, and Healthy People 2030 national targets were not met. Disparities existed across several characteristics, particularly those related to health care access. Breast, cervical, and colonoscopy test use within recommended screening intervals approximated prepandemic levels. FOBT/FIT estimates were modestly higher in 2021. |
A comprehensive analysis of neuroblastoma incidence, survival, and racial and ethnic disparities from 2001 to 2019
Campbell K , Siegel DA , Umaretiya PJ , Dai S , Heczey A , Lupo PJ , Schraw JM , Thompson TD , Scheurer ME , Foster JH . Pediatr Blood Cancer 2023 71 (1) e30732 BACKGROUND: We characterize the incidence and 5-year survival of children and adolescents with neuroblastoma stratified by demographic and clinical factors based on the comprehensive data from United States Cancer Statistics (USCS) and the National Program of Cancer Registries (NPCR). METHODS: We analyzed the incidence of neuroblastoma from USCS (2003-2019) and survival data from NPCR (2001-2018) for patients less than 20 years old. Incidence trends were calculated by average annual percent change (AAPC) using joinpoint regression. Differences in relative survival were estimated comparing non-overlapping confidence intervals (CI). RESULTS: We identified 11,543 primary neuroblastoma cases in USCS. Age-adjusted incidence was 8.3 per million persons [95% CI: 8.2, 8.5], with an AAPC of 0.4% [95% CI: -0.1, 0.9]. Five-year relative survival from the NPCR dataset (n = 10,676) was 79.7% [95% CI: 78.9, 80.5]. Patients aged less than 1 year had the highest 5-year relative survival (92.5%). Five-year relative survival was higher for non-Hispanic White patients (80.7%) or Hispanic patients (80.8%) compared to non-Hispanic Black patients (72.6%). CONCLUSION: Neuroblastoma incidence was stable during 2003-2019. Differences in relative survival exist by sex, age, race/ethnicity, and stage; patients who were male, older, non-Hispanic Black, or with distant disease had worse survival. Future studies could seek to assess the upstream factors driving disparities in survival, and evaluate interventions to address inequities and improve survival across all groups. |
Variation in hysterectomy prevalence and trends among U.S. States and Territories-Behavioral Risk Factor Surveillance System, 2012-2020
Gopalani SV , Dasari SR , Adam EE , Thompson TD , White MC , Saraiya M . Cancer Causes Control 2023 34 (10) 829-835 PURPOSE: We estimated up-to-date state- and territory-level hysterectomy prevalence and trends, which can help correct the population at risk denominator and calculate more accurate uterine and cervical cancer rates. METHODS: We analyzed self-reported data for a population-based sample of 1,267,013 U.S. women aged ≥ 18 years who participated in the Behavioral Risk Factor Surveillance System surveys from 2012 to 2020. Estimates were age-standardized and stratified by sociodemographic characteristics and geography. Trends were assessed by testing for any differences in hysterectomy prevalence across years. RESULTS: Hysterectomy prevalence was highest among women aged 70-79 years (46.7%) and ≥ 80 years (48.8%). Prevalence was also higher among women who were non-Hispanic (NH) Black (21.3%), NH American Indian and Alaska Native (21.1%), and from the South (21.1%). Hysterectomy prevalence declined by 1.9 percentage points from 18.9% in 2012 to 17.0% in 2020. CONCLUSIONS: Approximately one in five U.S. women overall and half of U.S. women aged ≥ 70 years reported undergoing a hysterectomy. Our findings reveal large variations in hysterectomy prevalence within and between each of the four census regions and by race and other sociodemographic characteristics, underscoring the importance of adjusting epidemiologic measures of uterine and cervical cancers for hysterectomy status. |
Breast and colorectal cancer recurrence-free survival estimates in the US: Modeling versus active data collection
Mariotto AB , Thompson TD , Johnson C , Wu XC , Pollack LA . Cancer Epidemiol 2023 85 102370 BACKGROUND: A modeling method was developed to estimate recurrence-free survival using cancer registry survival data. This study aims to validate the modeled recurrence-free survival against "gold-standard" estimates from data collected by the National Program of Cancer Registries (NPCR) Patient-Centered Outcomes Research (PCOR) project. METHODS: We compared 5-year metastatic recurrence-free survival using modeling and empirical estimates from the PCOR project that collected disease-free status, tumor progression and recurrence for colorectal and female breast cancer cases diagnosed in 2011 in 5 U.S. state registries. To estimate empirical recurrence-free survival, we developed an algorithm that combined disease-free, recurrence, progression, and date information from NPCR-PCOR data. We applied the modeling method to relative survival for patients diagnosed with female breast and colorectal cancer in 2000-2015 in the SEER-18 areas. RESULTS: When grouping patients with stages I-III, the 5-year metastatic recurrence-free modeled and NPCR-PCOR estimates are very similar being respectively, 90.2 % and 88.6 % for female breast cancer, 74.6 % and 75.3 % for colon cancer, and 68.8 % and 68.5 % for rectum cancer. In general, the 5-year recurrence-free NPCR-PCOR and modeled estimates are still similar when controlling by stage. The modeled estimates, however, are not as accurate for recurrence-free survival in years 1-3 from diagnosis. CONCLUSIONS: The alignment between NPCR-PCOR and modeled estimates supports their validity and provides robust population-based estimates of 5-year metastatic recurrence-free survival for female breast, colon, and rectum cancers. The modeling approach can in principle be extended to other cancer sites to provide provisional population-based estimates of 5-year recurrence free survival. |
Visualizing Cancer Incidence and Mortality Estimates by Congressional Districts, United States 2012-2016
Senkomago V , Thompson TD , Scott LC , Singh SD , O'Neil ME , Wilson R , King JB , Jim MM , Lu H , Wu M , Benard VB , Richardson LC . J Registry Manag 2020 47 (2) 67-79 BACKGROUND: Cancer incidence and death rates in the United States are often published at the county or statelevels; examining cancer statistics at the congressional district (CD) level allows decision makers to better understand how cancer is impacting the specific populations they represent. METHODS: Cancer incidence data were obtained from the Centers for Disease Control and Prevention's National Program of Cancer Registries and the National Cancer Institute's Surveillance, Epidemiology, and End Results Program. Mortality data were obtained from the National Center for Health Statistics. CD rates were estimated by assigning the county-level age-adjusted rates to the census block and weighting those by the block population proportion of the CD. Those weighted rates were then aggregated over the blocks within the CD to estimate the district rate. Incidence rate estimates for 406 CDs and death rate estimates for 436 CDs were reported according to the boundaries for the 115th Congress of the United States. Maps showing rate estimates for all cancers combined, lung/bronchus, colorectal, female breast, cervical, and prostate cancer are presented by sex and race/ethnicity. RESULTS: The distribution of cancer incidence and death rates by CDs show similar patterns to those that have been observed at the county and state levels, with the highest cancer incidence and death rates observed in CDs in the South and Eastern regions. CONCLUSION: This examination of cancer rates at the CD-level provides data that can be used to inform cancer control strategies at the local and national levels. Displaying the data with the Data Visualizations tool makes it easily accessible to the public and decision makers. |
Comparing Human Papillomavirus Prevalence in Rectal and Anal Cancer Using US Cancer Registries, 2014-2015
Mix J , Saraiya M , Lynch CF , Thompson TD , Greek A , Tucker TC , Peters ES , Querec TD , Unger ER . J Registry Manag 2019 46 (4) 128-132 BACKGROUND AND AIMS: Rectal squamous cell carcinoma (SCC) is a rare malignancy, and the causal role of human papillomavirus (HPV) in these cancers is thought to be similar to anal cancer. We compared type-specific prevalence of HPV in rectal SCC to anal cancer. In rectal SCC, we evaluated the agreement between HPV prevalence and positivity for p16, a marker of oncogenic activity. METHODS: A stratified random sample of rectal SCCs and anal cancers diagnosed between 2014 and 2015 were identified from 3 statewide cancer registries in Iowa, Kentucky, and Louisiana. HPV testing was performed at the HPV laboratory at the Centers for Disease Control and Prevention. HPV types were described using hierarchical attribution to HPV16 and other oncogenic types, weighted for sampling design. In rectal SCC, we computed concordance and Cohen's kappa coefficient (κ) between HPV status and p16 positivity. RESULTS: A total of 39 rectal and 72 anal cancers were analyzed. HPV16 was the most common type in both rectal and anal cancer and did not differ significantly between sites (71.4% vs 82.1%; P = .32). Concordance between the presence of any HPV type and p16 positivity in rectal SCC was 92% with κ = 0.77. CONCLUSIONS: Rectal SCC and anal cancer have similar type-specific HPV prevalence, with HPV16 found most frequently. Substantial agreement between p16 and HPV status in rectal SCC lends additional support for the etiologic role of HPV in both anal and rectal cancer. Larger studies could be conducted to replicate these findings. |
Cancer distribution Among Asian, Native Hawaiian, and Pacific Islander subgroups - United States, 2015-2019
Bock S , Henley SJ , O'Neil ME , Singh SD , Thompson TD , Wu M . MMWR Morb Mortal Wkly Rep 2023 72 (16) 421-425 Non-Hispanic Asian (Asian) and non-Hispanic Native Hawaiian and Pacific Islander (NHPI) persons represent growing segments of the U.S. population (1). Epidemiologic cancer studies often aggregate Asian and NHPI persons (2,3); however, because Asian and NHPI persons are culturally, geographically, and linguistically diverse (2,4), subgroup analyses might provide insights into the distribution of health outcomes. To examine the frequency and percentage of new cancer cases among 25 Asian and NHPI subgroups, CDC analyzed the most current 2015-2019 U.S. Cancer Statistics data.* The distribution of new cancer cases among Asian and NHPI subgroups differed by sex, age, cancer type, and stage at diagnosis (for screening-detected cancers). The percentage of cases diagnosed among females ranged from 47.1% to 68.2% and among persons aged <40 years, ranged from 3.1% to 20.2%. Among the 25 subgroups, the most common cancer type varied. For example, although breast cancer was the most common in 18 subgroups, lung cancer was the most common cancer among Chamoru, Micronesian race not otherwise specified (NOS), and Vietnamese persons; colorectal cancer was the most common cancer among Cambodian, Hmong, Laotian, and Papua New Guinean persons. The frequency of late-stage cancer diagnoses among all subgroups ranged from 25.7% to 40.3% (breast), 38.1% to 61.1% (cervical), 52.4% to 64.7% (colorectal), and 70.0% to 78.5% (lung). Subgroup data illustrate health disparities among Asian and NHPI persons, which might be reduced through the design and implementation of culturally and linguistically responsive cancer prevention and control programs, including programs that address social determinants of health. |
Updated estimate of the annual direct medical cost of screening and treatment for human papillomavirus associated disease in the United States
Clay PA , Thompson TD , Markowitz LE , Ekwueme DU , Saraiya M , Chesson HW . Vaccine 2023 41 (14) 2376-2381 The annual direct medical cost attributable to human papillomavirus (HPV) in the United States over the period 2004-2007 was estimated at $9.36 billion in 2012 (updated to 2020 dollars). The purpose of this report was to update that estimate to account for the impact of HPV vaccination on HPV-attributable disease, reductions in the frequency of cervical cancer screening, and new data on the cost per case of treating HPV-attributable cancers. Based primarily on data from the literature, we estimated the annual direct medical cost burden as the sum of the costs of cervical cancer screening and follow-up and the cost of treating HPV-attributable cancers, anogenital warts, and recurrent respiratory papillomatosis (RRP). We estimated the total direct medical cost of HPV to be $9.01 billion annually over the period 2014-2018 (2020 U.S. dollars). Of this total cost, 55.0% was for routine cervical cancer screening and follow-up, 43.8% was for treatment of HPV-attributable cancer, and less than 2% was for treating anogenital warts and RRP. Although our updated estimate of the direct medical cost of HPV is slightly lower than the previous estimate, it would have been substantially lower had we not incorporated more recent, higher cancer treatment costs. |
Risk of clear-cell adenocarcinoma of the vagina and cervix among US women with potential exposure to diethylstilbestrol in utero
White MC , Weir HK , Soman AV , Peipins LA , Thompson TD . Cancer Causes Control 2022 33 (8) 1121-1124 PURPOSE: Women exposed to diethylstilbestrol (DES) in utero were at elevated risk of clear-cell adenocarcinoma of the vagina and cervix (CCA) as young women. Previous research suggested that this elevated risk of CCA may persist into adulthood. We extended a published analysis to measure CCA risk as these women aged. METHODS: Standardized incidence ratios (SIR) compared CCA risk among women born from 1947 through 1971 (the DES-era) to CCA risk among the comparison group of women born prior to 1947, using registry data that covered the US population. RESULTS: Incidence rates of CCA among both cohorts increased with age. Among the DES-era birth cohort, higher rates of CCA were observed across all age groups except 55-59 years. SIR estimates had wide confidence intervals that often included the null value. CONCLUSIONS: Results are consistent with prior research and suggest an elevated risk of CCA in midlife and at older ages among women exposed in utero to DES. These results highlight unresolved issues regarding cancer risk among aging DES daughters and appropriate screening guidance. The examination of population-based cancer surveillance data may be a useful tool for monitoring trends in the incidence of other rare cancers over time among specific birth cohorts. |
Cancer screening test use-U.S., 2019
Sabatino SA , Thompson TD , White MC , Shapiro JA , Clarke TC , Croswell JM , Richardson LC . Am J Prev Med 2022 63 (3) 431-439 INTRODUCTION: The U.S. Preventive Services Task Force recommends breast, cervical, and colorectal cancer screening to reduce mortality from these cancers, but screening use has been below national targets. The purpose of this study is to examine the proportion of screening-eligible adults who are up to date with these screenings and how screening use compares with Healthy People 2020 targets. METHODS: Data from the 2019 National Health Interview Survey were used to examine the percentages of adults up to date with breast cancer screening among women aged 5074 years without previous breast cancer, cervical cancer screening among women aged 2165 years without previous cervical cancer or hysterectomy, and colorectal cancer screening among adults aged 5075 years without previous colorectal cancer. Estimates are presented by sociodemographic characteristics and healthcare access factors. Analyses were conducted in 2021. RESULTS: Percentages of adults up to date were 76.2% (95% CI= 75.0, 77.5) for breast cancer screening, 76.4% (95% CI= 75.2, 77.6) for cervical cancer screening, and 68.3% (95% CI= 67.3, 69.3) for colorectal cancer screening. Although some population subgroups met breast and colorectal cancer screening targets (81.1% and 70.5%, respectively), many did not, and cervical cancer screening was below the target for all examined subgroups. Lower education and income, nonmetropolitan county of residence (which included rural counties), no usual source of care or health insurance coverage, and Medicaid coverage were associated with lower screening test use. CONCLUSIONS: Estimated use of breast, cervical, and colorectal cancer screening tests based on the 2019 National Health Interview Survey were below national targets. Continued monitoring may allow for examination of screening trends, inform interventions, and track progress in eliminating disparities. |

Celtik K , Wallis CJD , Lo M , Lim K , Lipscomb J , Fleming S , Wu XC , Anderson RT , Thompson TD , Farach A , Hamilton AS , Miles BJ , Satkunasivam R . Can Urol Assoc J 2022 16 (7) E391-E398 INTRODUCTION: Limited evidence exists on the comparative effectiveness of local treatments for prostate cancer (PCa) due to the lack of generalizability. Using granular national data, we sought to examine the association between radical prostatectomy (RP) and intensity-modulated radiation therapy (IMRT) treatment and survival. METHODS: Records were abstracted for localized PCa cases diagnosed in 2004 across seven state registries to identify patients undergoing RP (n=3019) or IMRT (n=667). Comorbidity was assessed by the Adult Comorbidity Evaluation-27 (ACE-27). Propensity score matching (PSM) was used to balance covariates between treatment groups. All-cause and PCa-specific mortality were primary endpoints. A subgroup analysis of patients with high-risk PCa (RP, n=89; IMRT, n=95) was conducted. RESULTS: Following PSM, matched patients (n=502 pairs) treated with either RP or IMRT were well-balanced with respect to covariates. With a median followup of 10.5 years (interquartile range [IQR] 9.9-11.0), the 11-year overall survival (OS) was 71.2% (95% confidence interval [CI] 66.9-75.8) for RP and 62.3% (95% CI 57.4-67.6) for IMRT. IMRT was associated with a 41% increased risk of all-cause mortality (hazard ratio [HR] 1.41, 95% CI 1.13-1.76) but not PCa-specific mortality (HR 1.75, 95% CI 0.84-3.64), as compared to RP. In patients with high-risk PCa, IMRT, as compared to RP, was not associated with statistically significant difference in all-cause (HR 1.53, 95% CI 0.97-2.42) or PCa-specific mortality (HR 1.92, 95% CI 0.69-5.36). CONCLUSIONS: Despite a low mortality rate at 10 years and possible residual confounding, we found a significantly increased risk of all-cause mortality, but no PCa-specific mortality associated with IMRT as compared to RP in this population-based study. |
Impact of Relative Dose Intensity of FOLFOX Adjuvant Chemotherapy on Risk of Death Among Stage III Colon Cancer Patients
Zhou M , Thompson TD , Lin HY , Chen VW , Karlitz JJ , Fontham ETH , Theall KP , Zhang L , Hsieh MC , Pollack LA , Wu XC . Clin Colorectal Cancer 2021 21 (2) e62-e75 BACKGROUND: The National Comprehensive Cancer Network (NCCN) guidelines have recommended tailored chemotherapy for stage III high-risk (T4 and/or N2) and low-risk (T1-T3 and N1) colon cancer since 2018. Studies have investigated the effect of relative dose intensity (RDI) of FOLFOX on stage III colon cancer survival, however, none has performed a stratified analysis by risk profiles. This study aims to identify the FOLFOX optimal RDI for high-risk and low-risk stage III colon cancer patients. METHODS: Data on 407 eligible patients, diagnosed with stage III colon cancer in 2011 who received FOLFOX, were collected by 8 population-based cancer registries. Multivariable Cox model and Fine-Gray competing risks model were employed to explore Optimal RDI defined as the lowest RDI administered without significant differences in either overall or cause-specific death. RESULTS: Among the 168 high-risk patients, the optimal RDI cut-off was 70% (HR = 1.59 with 95% CI: 0.69-3.66 in overall mortality; HR = 1.24 with 95% CI: 0.42-3.64 in cause-specific mortality when RDI < 70% vs. RDI ≥ 70%). Among the 239 low-risk patients, none of the evaluated cut-offs were associated with significant differences in risk of death between comparison groups. The lowest assessed RDI was 45%, HR = 0.80; 95% CI: 0.24 to 2.73 for overall mortality and HR = 0.53; 95% CI: 0.06 to 4.95 for cause-specific mortality, when RDI <45% versus RDI ≥45%. CONCLUSIONS: There is no significant harm on the risk of death when reducing RDI by <30% for high-risk patients. For the low-risk patients, we found that RDI as low as 45% did not significantly affect the risk of death. |
Prevalence of human papillomavirus genotypes in high-grade cervical precancer and invasive cervical cancer from cancer registries before and after vaccine introduction in the United States.
Mix JM , Saraiya M , Thompson TD , Querec TD , Greek A , Tucker TC , Peters ES , Lynch CF , Hernandez BY , Copeland G , Goodman MT , Unger ER . Cancer 2021 127 (19) 3614-3621 ![]() BACKGROUND: US population-based cancer registries can be used for surveillance of human papillomavirus (HPV) types found in HPV-associated cancers. Using this framework, HPV prevalence among high-grade cervical precancers and invasive cervical cancers were compared before and after HPV vaccine availability. METHODS: Archived tissue from 2 studies of cervical precancers and invasive cervical cancers diagnosed from 1993-2005 (prevaccine) were identified from 7 central cancer registries in Florida; Hawaii; Iowa; Kentucky; Louisiana; Los Angeles County, California; and Michigan; from 2014 through 2015 (postvaccine) cases were identified from 3 registries in Iowa, Kentucky, and Louisiana. HPV testing was performed using L1 consensus polymerase chain reaction analysis. HPV-type-specific prevalence was examined grouped by hierarchical attribution to vaccine types: HPV 16, 18, HPV 31, 33, 45, 52, 58, other oncogenic HPV types, and other types/HPV negative. Generalized logit models were used to compare HPV prevalence in the prevaccine study to the postvaccine study by patient age, adjusting for sampling factors. RESULTS: A total of 676 precancers (328 prevaccine and 348 postvaccine) and 1140 invasive cervical cancers (777 prevaccine and 363 postvaccine) were typed. No differences were observed in HPV-type prevalence by patient age between the 2 studies among precancers or invasive cancers. CONCLUSIONS: The lack of reduction in vaccine-type prevalence between the 2 studies is likely explained by the low number of cases and low HPV vaccination coverage among women in the postvaccine study. Monitoring HPV-type prevalence through population-based strategies will continue to be important in evaluating the impact of the HPV vaccine. |
Cancer Incidence Projections in the United States Between 2015 and 2050
Weir HK , Thompson TD , Stewart SL , White MC . Prev Chronic Dis 2021 18 E59 INTRODUCTION: The number of adults entering the age groups at greatest risk for being diagnosed with cancer is increasing. Projecting cancer incidence can help the cancer control community plan and evaluate prevention strategies aimed at reducing the growing number of cancer cases. METHODS: We used data from the Surveillance, Epidemiology, and End Results Program and the US Census Bureau to estimate average, annual, age-standardized cancer incidence rates and case counts (for all sites combined and top 22 invasive cancers) in the US for 2015 and to project cancer rates and counts to 2050. We used age, period, and cohort models to inform projections. RESULTS: Between 2015 and 2050, we predict the overall age-standardized incidence rate (proxy for population risk for being diagnosed with cancer) to stabilize in women (1%) and decrease in men (-9%). Cancers with the largest change in risk include a 34% reduction for lung and bronchus and a 32% increase for corpus uterine (32%). Because of the growth and aging of the US population, we predict that the annual number of cancer cases will increase 49%, from 1,534,500 in 2015 to 2,286,300 in 2050, with the largest percentage increase among adults aged ≥75 years. Cancers with the largest projected absolute increase include female breast, colon and rectum, and prostate. DISCUSSION: By 2050, we predict the total number of incident cases to increase by almost 50% as a result of the growth and aging of the US population. A greater emphasis on cancer risk reduction is needed to counter these trends. |
Cancer screening test receipt - United States, 2018
Sabatino SA , Thompson TD , White MC , Shapiro JA , de Moor J , Doria-Rose VP , Clarke T , Richardson LC . MMWR Morb Mortal Wkly Rep 2021 70 (2) 29-35 Screening for breast cancer, cervical cancer, and colorectal cancer (CRC) reduces mortality from these cancers.* However, screening test receipt has been below national targets with disparities observed in certain populations (1,2). National Health Interview Survey (NHIS) data from 2018 were analyzed to estimate percentages of adults up to date with U.S. Preventive Services Task Force (USPSTF) screening recommendations. Screening test receipt remained below national Healthy People 2020 (HP2020) targets, although CRC test receipt neared the target. Disparities were evident, with particularly low test receipt among persons who were uninsured or did not have usual sources of care. Continued monitoring helps assess progress toward targets and could inform efforts to promote screening and reduce barriers for underserved populations. |
Breast and colorectal cancer recurrence and progression captured by five U.S. population-based registries: Findings from National Program of Cancer Registries patient-centered outcome research
Thompson TD , Pollack LA , Johnson CJ , Wu XC , Rees JR , Hsieh MC , Rycroft R , Culp M , Wilson R , Wu M , Zhang K , Benard V . Cancer Epidemiol 2020 64 101653 OBJECTIVES: Cancer recurrence is a meaningful patient outcome that is not captured in population-based cancer surveillance. This project supported National Program of Cancer Registries central cancer registries in five U.S. states to determine the disease course of all breast and colorectal cancer cases. The aims were to assess the feasibility of capturing disease-free (DF) status and subsequent cancer outcomes and to explore analytic approaches for future studies. METHODS: Data were obtained on 11,769 breast and 6033 colorectal cancer cancers diagnosed in 2011. Registry-trained abstractors reviewed medical records from multiple sources for up to 60 months to determine documented DF status, recurrence, progression and residual disease. We described the occurrence of these patient-centered outcomes along with analytic considerations when determining time-to-event outcomes and recurrence-free survival. RESULTS: Disease-free status was determined on all but 3.8 % of cancer cases. Among 14,458 cases that became DF, 6.1 % of breast and 13.0 % of colorectal cancer cases had a documented recurrence. Recurrence-free survival varied by stage; for stage II-III cancers at 48 months, 83.2 % of female breast and 69.2 % of colorectal cancer patients were alive without recurrence. The ability to distinguish between progression and residual disease among never disease-free patients limited our ability to examine progression as an outcome. CONCLUSIONS: This study demonstrated that population-based registries given intense support and resources can capture recurrence and offer a generalizable picture of cancer outcomes. Further work on refining definitions, sampling strategies, and novel approaches to capture recurrence could advance the ability of a national cancer surveillance system to contribute to patient-centered outcomes research. |
Human papillomavirus DNA detection, p16 INK4a , and oral cavity cancer in a U.S. population
Hernandez BY , Lynch CF , Chan OTM , Goodman MT , Unger ER , Steinau M , Thompson TD , Gillison M , Lyu C , Saraiya M . Oral Oncol 2019 91 92-96 Objectives: The role of HPV in oral cavity cancers was investigated using two markers of viral exposure. Materials and methods: HPV DNA and p16 INK4a expression were evaluated in tumor tissue from a U.S. population-based sample of 122 invasive oral cavity cancer cases. Results: HPV DNA was detected in 38 of 122 (31%) oral cavity tumors. Seven genotypes were detected including HPV 16, which was found in 22% of tumors. p16 INK4a was expressed in 30% of tumors and was poorly correlated with HPV DNA detection (Kappa <0.1). Joint positivity for HPV 16 and/or 18 and p16 INK4a was observed in only 7% of cases. When comparing cases diagnosed in 1993–1999 and in 2000–2004, positivity for HPV DNA 16/18 increased from 19% to 39% (p = 0.02) and joint HPV 16/18 – p16 INK4a positivity increased from 0% to 12% (p = 0.01). For gingival tumors, HPV 16 and/or 18 positivity was 67% compared to 11–38% for other sites (p = 0.02); joint HPV 16/18 – p16 INK4a positivity was 33% compared to 0–8% for other sites (p = 0.01). The association of HPV with gingival tumors and more recent diagnosis period remained after adjustment for age and stage (p < 0.05). Neither HPV DNA nor p16 INK4a were associated with overall survival. Conclusions: Based on both HPV DNA and p16 INK4a , HPV is etiologically linked to a limited subset of oral cavity cancers. However, the role of HPV in oral cavity cancer may vary widely by subsite and may have increased over time, similar to trends observed for oropharyngeal cancer. © 2019 Elsevier Ltd |
Population-Based Assessment of HPV Genotype-Specific Cervical Cancer Survival: CDC Cancer Registry Sentinel Surveillance System.
Hallowell BD , Saraiya M , Thompson TD , Unger ER , Lynch CF , Tucker T , Copeland G , Hernandez BY , Peters ES , Wilkinson E , Goodman MT . JNCI Cancer Spectr 2018 2 (3) ![]() Background: Human papillomavirus (HPV) genotype influences the development of invasive cervical cancer (ICC); however, there is uncertainty regarding the association of HPV genotype with survival among ICC patients. Method(s): Follow-up data were collected from 693 previously selected and HPV-typed ICC cases that were part of the Centers for Disease Control and Prevention Cancer Registry Surveillance System. Cases were diagnosed between 1994 and 2005. The Kaplan-Meier method was used to estimate five-year all-cause survival. A multivariable Cox proportional hazards model was used to estimate the effect of HPV genotype on survival after adjusting for demographic, tumor, and treatment characteristics. Result(s): Five-year all-cause survival rates varied by HPV status (HPV 16: 66.9%, HPV 18: 65.7%, HPV 31/33/45/52/58: 70.8%, other oncogenic HPV genotypes: 79.0%, nononcogenic HPV: 69.3%, HPV-negative: 54.0%). Following multivariable adjustment, no statistically significant survival differences were found for ICC patients with HPV 16-positive tumors compared with women with tumors positive for HPV 18, other oncogenic HPV types, or HPV-negative tumors. Women with detectable HPV 31/33/33/ 45/52/58 had a statistically significant 40% reduced hazard of death at five years (95% confidence interval [CI] = 0.38 to 0.95), and women who tested positive for nononcogenic HPV genotypes had a statistically significant 57% reduced hazard of death at five years (95% CI = 0.19 to 0.96) compared with women with HPV 16 tumors. Few statistically significant differences in HPV positivity, tumor characteristics, treatment, or survival were found by race/ethnicity. Conclusion(s): HPV genotype statistically significantly influenced five-year survival rates among women with ICC; however, screening and HPV vaccination remain the most important factors to improve patient prognosis and prevent future cases. |
Prevalence of out-of-pocket payments for mammography screening among recently screened women
Sabatino SA , Thompson TD , Miller JW , Breen N , White MC , Breslau E , Shoemaker ML . J Womens Health (Larchmt) 2018 28 (7) 910-918 BACKGROUND: Because cost may be a barrier to receiving mammography screening, cost sharing for "in-network" screening mammograms was eliminated in many insurance plans with implementation of the Affordable Care Act. We examined prevalence of out-of-pocket payments for screening mammography after elimination in many plans. MATERIALS AND METHODS: Using 2015 National Health Interview Survey data, we examined whether women aged 50-74 years who had screening mammography within the previous year (n = 3,278) reported paying any cost for mammograms. Logistic regression models stratified by age (50-64 and 65-74 years) examined out-of-pocket payment by demographics and insurance (ages 50-64 years: private, Medicaid, other, and uninsured; ages 65-74 years: private +/- Medicare, Medicare+Medicaid, Medicare Advantage, Medicare only, and other). RESULTS: Of women aged 50-64 years, 23.5% reported payment, including 39.1% of uninsured women. Compared with that of privately insured women, payment was less likely for women with Medicaid (adjusted OR 0.17 [95% CI 0.07-0.41]) or other insurance (0.49 [0.25-0.96]) and more likely for uninsured women (1.99 [0.99-4.02]) (p < 0.001 across groups). For women aged 65-74 years, 11.9% reported payment, including 22.5% of Medicare-only beneficiaries. Compared with private +/- Medicare beneficiaries, payment was less likely for Medicare+Medicaid beneficiaries (adjusted OR 0.21 [95% CI 0.06-0.73]) and more likely for Medicare-only beneficiaries (1.83 [1.01-3.32]) (p = 0.005 across groups). CONCLUSIONS: Although most women reported no payment for their most recent screening mammogram in 2015, some payment was reported by >20% of women aged 50-64 years or aged 65-74 years with Medicare only, and by almost 40% of uninsured women aged 50-64 years. Efforts are needed to understand why many women in some groups report paying out of pocket for mammograms and whether this impacts screening use. |
Patterns and trends in cancer screening in the United States
Hall IJ , Tangka FKL , Sabatino SA , Thompson TD , Graubard BI , Breen N . Prev Chronic Dis 2018 15 E97 INTRODUCTION: We examined the prevalence of cancer screening reported in 2015 among US adults, adjusted for important sociodemographic and access-to-care variables. By using data from the National Health Interview Survey (NHIS) for 2000 through 2015, we examined trends in prevalence of cancer screening that adhered to US Preventive Services Task Force screening recommendations in order to monitor screening progress among traditionally underserved population subgroups. METHODS: We analyzed NHIS data from surveys from 2000 through 2015 to estimate prevalence and trends in use of recommended screening tests for breast, cervical, colorectal, and prostate cancers. We used logistic regression and report predictive margins for population subgroups adjusted for various socioeconomic and demographic variables. RESULTS: Colorectal cancer screening was the only test that increased during the study period. We found disparities in prevalence of test use among subgroups for all tests examined. Factors that reduced the use of screening tests included no contact with a doctor in the past year, no usual source of health care, and no insurance coverage. CONCLUSION: Understanding use of cancer screening tests among different population subgroups is vital for planning public health interventions with potential to increase screening uptake and reduce disparities in cancer morbidity and mortality. Overarching goals of Healthy People 2020 are to "achieve health equity, eliminate disparities, and improve the health of all groups." Adjusted findings for 2015, compared with previous years, show persistent screening disparities, particularly among the uninsured, and progress for colorectal cancer screening only. |
Five-year relative survival for human papillomavirus-associated cancer sites
Razzaghi H , Saraiya M , Thompson TD , Henley SJ , Viens L , Wilson R . Cancer 2017 124 (1) 203-211 BACKGROUND: Human papillomavirus (HPV) vaccines can potentially prevent greater than 90% of cervical and anal cancers as well as a substantial proportion of vulvar, vaginal, penile, and oropharyngeal cancers caused by certain HPV types. Because more than 38,000 HPV-associated cancers are diagnosed annually in the United States, current studies are needed to understand how relative survival varies for each of these cancers by certain demographic characteristics, such as race and age. METHODS: The authors examined high-quality data from 27 population-based cancer registries covering approximately 59% of the US population. The analyses were limited to invasive cancers that were diagnosed during 2001 through 2011 and followed through 2011 and met specified histologic criteria for HPV-associated cancers. Five-year relative survival was calculated from diagnosis until death for these cancers by age, race, and sex. RESULTS: The 5-year age-standardized relative survival rate was 64.2% for cervical carcinomas, 52.8% for vaginal squamous cell carcinomas (SCCs), 66% for vulvar SCCs, 47.4% for penile SCCs, 65.9% for anal SCCs, 56.2% for rectal SCCs, and 51.2% for oropharyngeal SCCs. Five-year relative survival was consistently higher among white patients compared with black patients for all HPV-associated cancers across all age groups; the greatest differences by race were observed for oropharyngeal SCCs among those aged <60 years and for penile SCCs among those ages 40 to 49 years compared with other age groups. CONCLUSIONS: There are large disparities in relative survival among patients with HPV-associated cancers by sex, race, and age. HPV vaccination and improved access to screening (of cancers for which screening tests are available) and treatment, especially among groups that experience higher incidence and lower survival, may reduce disparities in survival from HPV-associated cancers.

A comparison of fecal immunochemical and high-sensitivity guaiac tests for colorectal cancer screening
Shapiro JA , Bobo JK , Church TR , Rex DK , Chovnick G , Thompson TD , Zauber AG , Lieberman D , Levin TR , Joseph DA , Nadel MR . Am J Gastroenterol 2017 112 (11) 1728-1735 OBJECTIVES: Annual testing using either a high-sensitivity guaiac fecal occult blood test (HS-gFOBT) or a fecal immunochemical test (FIT) is recommended for screening average-risk people for colorectal cancer. We compared the performance characteristics of the HS-gFOBT Hemoccult II SENSA and two FITs (InSure FIT and OC FIT-CHEK) for detecting advanced colorectal neoplasia. METHODS: The study included 1,006 asymptomatic patients, aged 50-75 years, who were scheduled to receive a screening colonoscopy at gastroenterology practices in the Minneapolis and Indianapolis metropolitan areas. Each participant was asked to complete all three stool tests before their colonoscopy. Each test's performance characteristics were evaluated using the screening colonoscopic results as the reference standard. RESULTS: Sensitivity for detecting advanced colorectal neoplasia was highest for InSure FIT (26.3%, 95% confidence interval (CI) 15.9-40.7), followed by OC FIT-CHEK (15.1%, 95% CI 6.7-26.1) and Hemoccult II SENSA (7.4%, 95% CI 1.9-17.0). InSure FIT was statistically significantly more sensitive than both OC FIT-CHEK (absolute difference in sensitivity=11.2%, 95% CI 0.4-24.2) and Hemoccult II SENSA (difference in sensitivity=18.9%, 95% CI 10.2-32.6). Specificities were relatively high for all tests (between 96.8% and 98.6%). CONCLUSIONS: Our results suggest that some FITs are more sensitive than the HS-gFOBT Hemoccult II SENSA, but these results need to be confirmed in larger asymptomatic populations. Comparisons between the FITs examined in this study and other FITs are needed to determine the best tests for population screening.Am J Gastroenterol advance online publication, 10 October 2017; doi:10.1038/ajg.2017.285. |
Cancer screening test use - United States, 2015
White A , Thompson TD , White MC , Sabatino SA , de Moor J , Doria-Rose PV , Geiger AM , Richardson LC . MMWR Morb Mortal Wkly Rep 2017 66 (8) 201-206 Healthy People 2020 (HP2020) includes objectives to increase screening for breast, cervical, and colorectal cancer as recommended by the U.S. Preventive Services Task Force (USPSTF). Progress toward meeting these objectives is monitored by measuring cancer screening test use against national targets using data from the National Health Interview Survey (NHIS). Analysis of 2015 NHIS data indicated that screening test use remains substantially below HP2020 targets for selected cancer screening tests. Although colorectal cancer screening test use increased from 2000 to 2015, no improvements in test use were observed for breast and cervical cancer screening. Disparities exist in screening test use by race/ethnicity, socioeconomic status, and health care access indicators. Increased measures to implement evidence-based interventions and conduct targeted outreach are needed if the HP2020 targets for cancer screening are to be achieved and the disparities in screening test use are to be reduced. |
