Objectives: The roles of retinol, vitamins C and E, and carotenoids as risk factors for prostate carcinoma are still questionable. We evaluated these in the Netherlands Cohort Study.
Methods: The cohort study consisted of 58,279 men ages 55-69 years at baseline in 1986. After 6.3 years of follow-up, 642 incident prostate carcinoma cases were available for analysis. Intakes of retinol, vitamins C and E, and several carotenoids were measured by means of a 150-item semi-quantitative food-frequency questionnaire.
Results: In multivariate analyses a positive association with prostate cancer risk was observed for intake of beta-cryptoxanthin. Rate ratios (RRs) in increasing quintiles were 1.00 (ref), 0.94, 1.01, 1.16, 1.41; p-trend < 0.01. For intake of retinol, vitamins C and E and other carotenoids (alpha-carotene, beta-carotene, lycopene, and lutein/zeaxanthin) no effect on overall prostate cancer risk was found. RRs for vitamin supplement use were decreased, but not significantly. Among nondrinkers, nonsignificant inverse associations were observed for intake of retinol, alpha-carotene, and beta-carotene (RRs, highest vs lowest quintile, were 0.23, 0.60, and 0.76, respectively). Among drinkers, beta-cryptoxanthin was positively associated (RR highest vs lowest quintile = 1.40).
Conclusions: These data show a positive association between beta-cryptoxanthin and prostate cancer risk. Our study also shows inverse associations for retinol, alpha-carotene, and beta-carotene among nondrinkers; this suggests an interaction between vitamins and alcohol consumption, which needs confirmation. Lycopene was not associated with prostate cancer.

Purposes: This study aimed to clarify the clinical outcomes of Bacillus Calmette-Guérin (BCG) treatment in patients with urothelial carcinoma (UC) of the prostatic urethra.
Methods: Between August 2003 and January 2023, 428 patients with non-muscle-invasive UC received BCG treatment (Tokyo strain, 80 mg, ≥ 5 times) in our hospital; 39 had UC of the prostatic urethra. We evaluated the cumulative incidence of intravesical recurrence, progression (muscle-invasive bladder cancer [MIBC] or metastasis), and subsequent radical cystectomy after BCG treatment in patients with UC of the prostatic urethra.

The uncertain ferroptosis-related role of berberine in prostate cancer was explored using network pharmacology methodology. Integration of ferroptosis targets in prostate cancer from the Genecard database and berberine targets from the Traditional Chinese Medicine Systems Pharmacology and SwissTargetPrediction databases revealed 17 common targets. Among these, 10 hub genes, including CCNB1, CDK1, AURKA, AR, CDC42, ICAM1, TYMS, NTRK1, PTGS2, and SCD, were identified.

Purpose: This study focused on reducing the margin for prostate cancer treatment using magnetic resonance imaging-guided radiotherapy by investigating the intrafractional motion of the prostate and different motion-mitigation strategies.
Methods: We retrospectively analyzed intrafractional prostate motion in 77 patients with low- to intermediate-risk prostate cancer treated with five fractions of 7.25 Gy on a 1.

Background: Few studies have examined how cancer incidence varies by country of origin among United States Hispanic/Latino adults. Herein, we describe the incidence rates of cancer overall and for screen-detectable, tobacco-related, and obesity-related cancers among 16,415 participants in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL), an ongoing population-based cohort study of Hispanic/Latino adults from diverse backgrounds.
Methods: Cohort participant records were linked to the state cancer registries in New York, Florida, California, and Illinois to ascertain cancer incidence from baseline (2008-2011) through 2021.

Objective: Gliomas are the most common primary brain tumors in adults, and the role of hormone therapy (HT) in their development remains controversial. This study with a cohort design aimed to investigate the association between HT use and glioma risk using the data from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial.
Methods: We analyzed data from 75,335 women, aged 50-78, who were enrolled between 1993 and 2001.
