Racial/ethnic differences in trends of testicular germ cell tumor incidence in the United States, 1992-2021.

Background: Testicular germ cell tumors (TGCTs) are the most common cancers among young men in the United States. Incidence rates among non-Hispanic White (NHW) men historically have been much higher than the rates among other men. To study whether this pattern had changed, the authors examined trends in TGCT incidence for the years 1992-2021.

Maize consumption and circulating aflatoxin levels in Mexican middle- and older-aged adults: a cross-sectional analysis.

Background: Maize is frequently contaminated by aflatoxin B (AFB), an established liver carcinogen.

Objectives: The objective of this study is to estimate the effect of maize and maize tortilla consumption on AFB-lysine adduct (AFB-lys) concentrations in middle- and older-aged adults living in south and eastern Mexico.

Methods: We conducted a cross-sectional analysis in a representative sample of 915 adults aged ≥40 y living in south and eastern Mexico in 2018-2019.

Total testosterone, sex hormone-binding globulin, and free testosterone concentrations and risk of primary liver cancer: A prospective analysis of 200,000 men and 180,000 postmenopausal women.

In most countries, males have ~2-3 times higher incidence of primary liver cancer than females. Sex hormones have been hypothesized to contribute to these differences, but the evidence remains unclear. Using data from the UK Biobank, which included ~200,000 males and ~180,000 postmenopausal females who provided blood samples at recruitment, we estimated hazard ratios (HR) and 95% confidence intervals (CI) for a doubling in hormone concentration from multivariable adjusted Cox regression for circulating total testosterone, sex-hormone binding globulin (SHBG), and free testosterone concentrations and risk of primary liver cancer.

Liver Cancer: Progress and Priorities.

Liver cancer, the sixth most frequently occurring cancer in the world and the third most common cause of cancer mortality, has wide geographical variation in both incidence and mortality rates. At the end of the 20th century, incidence rates began declining in some high-rate areas and increasing in some lower-rate areas. These trends were undoubtedly driven by the shifting contributions of both well-established and more novel risk factors.

Use of cholesterol-lowering medications in relation to risk of primary liver cancer in the Clinical Practice Research Datalink.

Background: Although the relation between statin use and liver cancer risk has been extensively examined, few studies have examined other cholesterol-lowering medications in relation to liver cancer risk. The authors examined five classes of nonstatin medications and liver cancer risk.

Methods: A nested case-control including 3719 cases and 14,876 matched controls was conducted within the Clinical Practice Research Datalink.
