Purpose Physical activity may play a supportive role in cancer survivorship. However, evidence on the association between post-diagnosis physical activity and mortality among women with gynecological cancer remains limited and inconsistent. Methods We conducted a systematic review of the literature published between 1949 and January 2026. Eligible observational studies were identified, and random-effects meta-analyses were per...

Background Physical activity after cancer diagnosis may reduce mortality. However, systematic evidence for this association for men living with prostate cancer remains limited. Methods We searched PubMed, Embase, and CINAHL data bases from start to June 2025. Random-effects meta-analyses estimated summary hazard ratios (HRs) and 95% confidence intervals (CI) for all-cause mortality and prostate-cancer-specific mortality to ass...

Cognitive performance prediction may help identify early cognitive decline. However, the heterogeneity of research findings impedes the identification of key predictors. This study used 21,877 participants (25–74 years) from the German National Cohort (NAKO Gesundheitsstudie, NAKO) to systematically predict cognitive test scores based on brain structure, demographic, health-related, and cognitive data. Importantly, validation...

Objective Identifying potentially modifiable risk factors for ovarian cancer is essential for prevention because this cancer is predominantly detected at a late stage. Here, we estimated the relations of general adiposity and measures reflecting body fat distribution to the risk of epithelial ovarian cancer. Methods We ascertained 683 ovarian epithelial cancers (343 high-grade serous, 141 non-high grade serous) among 145,575 w...
