Assessing impact of HPV vaccination on cervical cancer incidence in women 15-29 years in the United States, 1999-2017: An ecologic study
Mix JM , Van Dyne EA , Saraiya M , Hallowell BD , Thomas CC . Cancer Epidemiol Biomarkers Prev 2020 30 (1) 30-37 BACKGROUND: To date, the human papillomavirus (HPV) vaccine impact on invasive cervical cancers in the United States has not been documented due, in part, to the time needed for cancer to develop, and to recent changes to cervical cancer screening guidelines and recommendations which complicate data interpretation. METHODS: We examined incidence rates of cervical squamous cell carcinoma (SCC) and adenocarcinoma (AC)among women aged 15-29 years diagnosed during 1999-2017 using population-based cancer registry data covering 97.8% of the US population. Trends were stratified by age and histology. The annual percent change in cervical cancer incidence per year was calculated using Joinpoint regression. RESULTS: During 1999-2017, SCC rates decreased 7.9% per year among women aged 15-20 years, 5.5% among women aged 21-24 years, and 2.3% among women aged 25-29 years. The declines in SCC rates were largest among women aged 15-20 years from 2011 to 2017, with a decrease of 22.5% per year. Overall, AC rates decreased 4.1% per year among women aged 15-20 years, 3.6% per year among women aged 21-24 years, and 1.6% per year among women 25-29 years. AC rates declined the most among women aged 15-20 years during 2005 to 2017, decreasing 11.2% per year. CONCLUSIONS: Since HPV vaccine introduction, both SCC and AC incidence rates declined among women aged 15-20 years, a group not typically screened for cervical cancer, suggesting HPV vaccine impact. IMPACT: Timely vaccination and improved screening and follow-up among recommended age groups could result in further reductions in invasive cervical cancer. |
Cancer mortality in the US-affiliated Pacific Islands, 2008-2013
Van Dyne EA , Saraiya M , White A , Novinson D , Senkomago V , Buenconsejo-Lum L . Hawaii J Health Soc Welf 2020 79 99-107 Cancer-related mortality in the US-Affiliated Pacific Island (USAPI) jurisdictions is unknown. This is the first ever reporting of cancer-related mortality in the USAPI using cancer registry data. The individual USAPI jurisdictions collected incident cancer data and submitted it to the Pacific Regional Central Cancer Registry (PRCCR). All cases reported to PRCCR (n = 3,118) with vital status of dead (n = 1,323) during 2008-2013 were examined. Cause of death was coded based on clinical information provided in the cancer registry. Incidencebased mortality (IBM) rates were calculated using SEER*Stat software and age adjusted to the US standard population. Total cancer IBM rates among males were highest in Palau (151.5 per 100,000), Republic of the Marshall Islands (RMI, 142.0), and Guam (133.2); rates were lowest in American Samoa (21.7), the Commonwealth of the Northern Mariana Islands (CNMI, 22.7), and the Federated States of Micronesia (FSM, 28.9). Total cancer IBM rates among females were highest in RMI (120.3 per 100,000), Palau (107.7), and Guam (72.2); rates were lowest in CNMI (19.0), FSM (23.2), and American Samoa (42.8). The median time from cancer diagnosis to death was 8-28 days in the Freely Associated States and 102-128 days in the Flag Territories. IBM rates were higher among individuals in USAPI jurisdictions than among Asian/ Pacific Islanders in Hawai'i for many cancers preventable through vaccination, smoking cessation, overweight and obesity prevention, and cancer screening. Geographic remoteness, underreporting, delay in reporting, and challenges with accurate death registration and certification led to lower IBM rates for some jurisdictions. These mortality data can help prioritize evidence-based interventions to reduce cancer-related deaths through risk factor reduction, early detection, and improved quality of life after a cancer diagnosis through palliative care. |

Van Dyne EA , Neaterour P , Rivera A , Bello-Pagan M , Adams L , Munoz-Jordan J , Baez P , Garcia M , Waterman SH , Reyes N , Richardson LC , Rivera-Garcia B , Sharp TM . Open Forum Infect Dis 2019 6 (1) ofy325 Background: Zika virus (ZIKV) infection has been associated with severe thrombocytopenia. We describe the incidence, clinical manifestations, and outcomes of patients with ZIKV infection and thrombocytopenia. Methods: We reviewed medical records of patients with ZIKV infection and thrombocytopenia (platelet count <100 x10(9) cells/L) in Puerto Rico during 2016. Severe thrombocytopenia was defined by platelet count <20 x10(9)/L or a platelet count <50 x10(9)/L and treatment for immune thrombocytopenia (ITP). Results: Of 37 878 patients with ZIKV infection, 47 (0.1%) had thrombocytopenia in the absence of an alternative etiology (1.4 cases/100 000 population), including 12 with severe thrombocytopenia. Most patients with thrombocytopenia were adult (77%) and male (53%). Platelet nadir occurred a median (range) of 6 (1-16) and 5 (0-34) days after symptom onset for patients with severe and nonsevere thrombocytopenia, respectively. Among patients with severe thrombocytopenia, all had bleeding, 33% were admitted to the intensive care unit, and 8% died; 50% were treated for ITP. Among 5 patients with severe thrombocytopenia who received intravenous immunoglobulin, the median platelet count increase (range) was 112 (65-202) x10(9)/L. In contrast, among 4 patients who received platelet transfusion, the median increase in platelet count (range) was 8.5 (-6 to 52) x10(9)/L. Conclusions: Patients with severe thrombocytopenia and ZIKV infection experienced prominent acute morbidity. Consistent with recommended management, administration of ITP treatments to such patients may be more efficacious than platelet transfusion in resolving thrombocytopenia. Severe thrombocytopenia should be considered a rare outcome of ZIKV infection. |
Establishing baseline cervical cancer screening coverage - India, 2015-2016
Van Dyne EA , Hallowell BD , Saraiya M , Senkomago V , Patel SA , Agrawal S , Ghosh A , Saraf D , Mehrotra R , Dhillon PK . MMWR Morb Mortal Wkly Rep 2019 68 (1) 14-19 Cervical cancer is the second leading cause of new cancer cases and cancer-related deaths among women in India, with an estimated 96,922 new cases and 60,078 deaths each year.* Despite the availability of effective low-cost screening options in India, limited access to screening and treatment services, diagnosis at a later stage, and low investment in health care infrastructure all contribute to the high number of deaths (1). In 2016 the Ministry of Health and Family Welfare of India recommended cervical cancer screening using visual inspection with acetic acid every 5 years for women aged 30-65 years (per World Health Organization [WHO] guidelines) (2,3). To establish a baseline for cervical cancer screening coverage, survey data were analyzed to estimate the percentage of women aged 30-49 years who had ever been screened for cervical cancer (defined as ever having had a cervix examination). Cervical cancer screening was estimated using data from the Fourth National Family Health Survey(dagger) (NFHS-4), a nationally representative survey conducted at the district level during 2015-2016, which included 699,686 Indian women aged 15-49 years. Lifetime cervical cancer screening prevalence was low (29.8%) and varied by geographic region, ranging from 10.0% in the Northeast Region to 45.2% in the Western Region. Prevalence of screening was higher among women with higher levels of education and household wealth, those who had ever been married, and urban residents. This screening prevalence can be used as a baseline indicator for cervical cancer screening in India in accordance with the WHO Noncommunicable Diseases Global Monitoring Framework during state-based programmatic rollout and program evaluation (4). |
Trends in human papillomavirus-associated cancers - United States, 1999-2015
Van Dyne EA , Henley SJ , Saraiya M , Thomas CC , Markowitz LE , Benard VB . MMWR Morb Mortal Wkly Rep 2018 67 (33) 918-924 Human papillomavirus (HPV) is a known cause of cervical cancer, as well as some oropharyngeal, vulvar, vaginal, penile, and anal cancers. To assess trends, characterized by average annual percent change (AAPC), in HPV-associated cancer incidence during 1999-2015, CDC analyzed data from cancer registries covering 97.8% of the U.S. POPULATION: A total of 30,115 new cases of HPV-associated cancers were reported in 1999 and 43,371 in 2015. During 1999-2015, cervical cancer rates decreased 1.6% per year; vaginal squamous cell carcinoma (SCC) rates decreased 0.6% per year; oropharyngeal SCC rates increased among both men (2.7%) and women (0.8%); anal SCC rates also increased among both men (2.1%) and women (2.9%); vulvar SCC rates increased (1.3%); and penile SCC rates remained stable. In 2015 oropharyngeal SCC (15,479 cases among men and 3,438 among women) was the most common HPV-associated cancer. Continued surveillance through high-quality cancer registries is important to monitor cancer incidence and trends in these potentially preventable cancers. |
Geographic variation in pediatric cancer incidence - United States, 2003-2014
Siegel DA , Li J , Henley SJ , Wilson RJ , Lunsford NB , Tai E , Van Dyne EA . MMWR Morb Mortal Wkly Rep 2018 67 (25) 707-713 Approximately 15,000 persons aged <20 years receive a cancer diagnosis each year in the United States (1). National surveillance data could provide understanding of geographic variation in occurrence of new cases to guide public health planning and investigation (2,3). Past research on pediatric cancer incidence described differences by U.S. Census region but did not provide state-level estimates (4). To adequately describe geographic variation in cancer incidence among persons aged <20 years in the United States, CDC analyzed data from United States Cancer Statistics (USCS) during 2003-2014 and identified 171,432 cases of pediatric cancer during this period (incidence = 173.7 cases per 1 million persons). The cancer types with the highest incidence rates were leukemias (45.7), brain tumors (30.9), and lymphomas (26.2). By U.S. Census region, pediatric cancer incidence was highest in the Northeast (188.0) and lowest in the South (168.0), whereas by state (including the District of Columbia [DC]), rates were highest in New Hampshire, DC, and New Jersey. Among non-Hispanic whites (whites) and non-Hispanic blacks (blacks), pediatric cancer incidence was highest in the Northeast, and the highest rates among Hispanics were in the South. The highest rates of leukemia were in the West, and the highest rates of lymphoma and brain tumors were in the Northeast. State-based differences in pediatric cancer incidence could guide interventions related to accessing care (e.g., in states with large distances to pediatric oncology centers), clinical trial enrollment, and state or regional studies designed to further explore variations in cancer incidence. |
Rates and trends of pediatric acute lymphoblastic leukemia - United States, 2001-2014
Siegel DA , Henley SJ , Li J , Pollack LA , Van Dyne EA , White A . MMWR Morb Mortal Wkly Rep 2017 66 (36) 950-954 Acute lymphoblastic leukemia (ALL) is the most prevalent cancer among children and adolescents in the United States, representing 20% of all cancers diagnosed in persons aged <20 years, or >3,000 new cases each year (1). Past studies reported increasing trends of ALL overall and among Hispanics, but these represented ≤28% of the U.S. population and did not provide state-based estimates (1-3). To describe U.S. ALL incidence rates and trends among persons aged <20 years during 2001-2014, CDC analyzed rigorous data (based on established publication criteria) from the United States Cancer Statistics data set, which includes incidence data on approximately 15,000 new cases per year of all types of invasive cancer among children and adolescents aged <20 years (4). The data set represented 98% of the U.S. population during the study period. Overall incidence of pediatric ALL during 2001-2014 was 34.0 cases per 1 million persons and among all racial/ethnic groups was highest among Hispanics (42.9 per 1 million). Both overall and among Hispanics, pediatric ALL incidence increased during 2001-2008 and remained stable during 2008-2014. ALL incidence was higher in the West than in any other U.S. Census region. State-specific data indicated that the highest rates of pediatric ALL incidence were in California, New Mexico, and Vermont. These demographic and geographic ALL incidence data might better inform public health interventions targeting the following areas: exposures to recognized risk factors for leukemia; ALL treatment, including clinical trial enrollment; survivorship care planning; and studies designed to understand the factors affecting changes in pediatric cancer incidence. |
