{"title":"Prostate Cancer: A Review.","authors":"Ruben Raychaudhuri, Daniel W Lin, R Bruce Montgomery","doi":"10.1001/jama.2025.0228","DOIUrl":"https://doi.org/10.1001/jama.2025.0228","url":null,"abstract":"<p><strong>Importance: </strong>Prostate cancer is the most common nonskin cancer in men in the US, with an estimated 299 010 new cases and 35 250 deaths in 2024. Prostate cancer is the second most common cancer in men worldwide, with 1 466 680 new cases and 396 792 deaths in 2022.</p><p><strong>Observations: </strong>The most common type of prostate cancer is adenocarcinoma (≥99%), and the median age at diagnosis is 67 years. More than 50% of prostate cancer risk is attributable to genetic factors; older age and Black race (annual incidence rate, 173.0 cases per 100 000 Black men vs 97.1 cases per 100 000 White men) are also strong risk factors. Recent guidelines encourage shared decision-making for prostate-specific antigen (PSA) screening. At diagnosis, approximately 75% of patients have cancer localized to the prostate, which is associated with a 5-year survival rate of nearly 100%. Based on risk stratification that incorporates life expectancy, tumor grade (Gleason score), tumor size, and PSA level, one-third of patients with localized prostate cancer are appropriate for active surveillance with serial PSA measurements, prostate biopsies, or magnetic resonance imaging, and initiation of treatment if the Gleason score or tumor stage increases. For patients with higher-risk disease, radiation therapy or radical prostatectomy are reasonable options; treatment decision-making should include consideration of adverse events and comorbidities. Despite definitive therapy, 2% to 56% of men with localized disease develop distant metastases, depending on tumor risk factors. At presentation, approximately 14% of patients have metastases to regional lymph nodes. An additional 10% of men have distant metastases that are associated with a 5-year survival rate of 37%. Treatment of metastatic prostate cancer primarily relies on androgen deprivation therapy, most commonly through medical castration with gonadotropin-releasing hormone agonists. For patients with newly diagnosed metastatic prostate cancer, the addition of androgen receptor pathway inhibitors (eg, darolutamide, abiraterone) improves survival. Use of abiraterone improved the median overall survival from 36.5 months to 53.3 months (hazard ratio, 0.66 [95% CI, 0.56-0.78]) compared with medical castration alone. Chemotherapy (docetaxel) may be considered, especially for patients with more extensive disease.</p><p><strong>Conclusions and relevance: </strong>Approximately 1.5 million new cases of prostate cancer are diagnosed annually worldwide.

All 3 secondary MRI outcomes reported significant differences favoring the vitamin D group vs the placebo group: MRI activity (89 patients [57.1%] vs 96 patients [65.3%]; HR, 0.71 [95% CI, 0.53-0.95]; P = .02), new lesions (72 patients [46.2%] vs 87 patients [59.2%]; HR, 0.61 [95% CI, 0.44-0.84]; P = .003), and contrast-enhancing lesions (29 patients [18.6%] vs 50 patients [34.0%]; HR, 0.47 [95% CI, 0.30-0.75]; P = .001). All 10 secondary clinical outcomes showed no significant difference, including relapse, which occurred in 28 patients (17.9%) in the vitamin D group vs 32 (21.8%) in the placebo group (HR, 0.69 [95% CI, 0.42-1.16]; P = .16). Results were similar in a subset of 247 patients meeting updated 2017 diagnostic criteria for relapsing-remitting MS at treatment initiation.
