Emerging cancer risks in BRCA2 pathogenic germline variant carriers.
Patrick R Benusiglio et al. Eur J Hum Genet 2023 9
From the paper: "Carriers of pathogenic germline variants (PGV) in BRCA2 could soon be offered gastric cancer screening using gastroscopy. In the longer term, some might even take part in lung cancer screening programs. Indeed, while the risks of breast, ovarian, pancreatic and prostate cancer have been documented for years, recent data show an increased risk of gastric cancer, and suggest an association with lung cancer. This article focuses specifically on BRCA2, while sidelining its sister gene BRCA1, as evidence for a broad cancer spectrum is much stronger for the former."
Assessing a Polygenic Risk Score for Lung Cancer Susceptibility in Non-Hispanic White and Black Populations.
Matthew R Trendowski et al. Cancer Epidemiol Biomarkers Prev 2023 8
Polygenic risk scores (PRS) have become an increasingly popular approach to evaluate cancer susceptibility, but have not adequately represented Black populations in model development. Methods: We used a previously published lung cancer PRS based on 80 SNPs associated with lung cancer risk in the OncoArray cohort and validated in UK Biobank. The PRS was evaluated for association with lung cancer risk adjusting for age, sex, total pack-years, family history of lung cancer, history of COPD, and the top five principal components for genetic ancestry.
Genetic Profiles Affect Smokers' Lung Cancer Risk
CN Martimez, Medscape, August 2023
Smokers with extreme phenotypes of high and low risk of developing tobacco-associated lung cancer have different genetic profiles, according to a multidisciplinary study conducted by specialists from the Cancer Center at the University of Navarra Clinic (CUN). The study was conducted using DNA from 133 heavy smokers who had not developed lung cancer at a mean age of 80 years, and from another 116 heavy smokers who had developed this type of cancer at a mean age of 50 years. This DNA was sequenced using next-generation techniques, and the results were analyzed using bioinformatics and artificial intelligence.
The Inflammatory Profile Correlates with COVID-19 Severity and Mortality in Cancer Patients
CE Budin et al, JPM, August 7, 2023
The correlation of the inflammatory profile with the severity of the disease in neoplastic patients with SARS-CoV-2 infection was addressed. A database of 1537 patients hospitalized in the pneumology department was analyzed. After applying the inclusion and exclusion criteria, 83 patients (67% males, 33% females) were included. Most of the analyzed patients were hospitalized with a moderate form of disease, explaining the significant percentage of 25% mortality. The frequency of the type of neoplasm was higher for lung cancer, followed by malignant colon tumor. We identified a significant association between the increased value of ferritin (p < 0.0001, OR = 22.31), fibrinogen (p = 0.009, OR = 13.41), and C-reactive protein (p = 0.01, OR = 7.65), respectively, and the level of severity of COVID-19.
