Association between Trichomonas vaginalis and prostate cancer mortality.

We previously observed a positive association between seropositivity for the parasite Trichomonas vaginalis and risk of clinically significant prostate cancer at diagnosis. Here, we examined whether T. vaginalis seropositivity was associated with increased prostate cancer-specific or all-cause mortality among prostate cancer patients.

A Prospective Study of Aspirin Use and Prostate Cancer Risk by Status.

In a case-control study, aspirin use was associated with a lower risk of a common prostate cancer molecular subtype, the gene fusion. We sought to validate this finding in a prospective cohort. In the Health Professionals Follow-up Study, 49,395 men reported on aspirin use on biennial questionnaires and were followed for prostate cancer incidence over 23 years.

Family History of Breast or Prostate Cancer and Prostate Cancer Risk.

Purpose: Breast and prostate cancer co-occur in families, and women with a family history of prostate cancer are at increased breast cancer risk. Prostate cancer is among the most heritable cancers, but few studies have investigated its association with familial breast cancer. The objective of this study is to investigate the extent to which familial breast or prostate cancer in first-degree relatives increases prostate cancer risk.
