Background: The G84E mutation in the HOXB13 gene has been associated with a high lifetime risk of prostate cancer in North America (about 20-fold). The geographical and ethnic extent of this recurrent allele has not yet been determined.
Methods: We assayed for the presence of the G84E mutation in 3,515 prostate cancer patients and 2,604 controls from Poland and estimated the odds ratio for prostate cancer associated with the allele.
Results: The G84E mutation was detected in 3 of 2,604 (0.1%) individuals from the general population in Poland and in 20 of 3,515 (0.6%) men with prostate cancer (Odds ratio [OR] = 5.0; 95% CI: 1.5-16.7; P = 0.008). The allele was present in 4 of 416 (1.0%) men with familial prostate cancer (OR = 8.4, 95% CI: 1.9-37.7; P = 0.005).
Conclusions: The G84E mutation predisposes to prostate cancer in Poland, but accounts for only a small proportion of cases. We expect that the G84E founder mutation might be present in other Slavic populations.

Clinical outcome of BCG treatment for patients with urothelial carcinoma of the prostatic urethra: Implications for early cystectomy.
World J Urol
January 2025
Department of Urology, Saint Marianna University School of Medicine, Kawasaki, Japan.
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.
Berberine inhibits prostate cancer progression by inducing ferroptosis: evidence from network pharmacology.
Anticancer Drugs
January 2025
School of Clinical Medicine, Zhaoqing Medical College, Zhaoqing, Guangdong, China.
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.

January 2025
Department of Radiation Oncology, Radboud university medical center, Nijmegen, The Netherlands.
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.
Cancer Incidence in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) - The Onco-SOL Ancillary Study.
Cancer Epidemiol Biomarkers Prev
January 2025
San Diego State University, San Diego, California, United States.
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.
Association between hormone therapy and glioma risk in US women: a cancer screening trial.
Menopause
January 2025
From the Department of Neurosurgery, Chongqing General Hospital, Chongqing University, Chongqing, China.
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.
