In men with prostate cancer on PSA screening, radical treatments led to half the incidence of metastasis and local progression as active monitoring without affecting disease-specific or overall survival.

In a prostate-cancer screening trial involving men with lesions shown on MRI, targeted biopsy alone detected half as many clinically insignificant tumors as targeted and systematic biopsy, with few significant tumors missed.

Patients with prostate cancer who have high-risk biochemical recurrence have an increased risk of progression. The efficacy and safety of enzalutamide plus androgen-deprivation therapy and enzalutamide monotherapy, as compared with androgen-deprivation therapy alone, are unknown. In this phase 3 trial, we enrolled patients with prostate cancer who had high-risk biochemical recurrence with a prostate-specific antigen doubling time of 9 months or less. Patients were randomly assigned, in a 1:1:1 ratio, to receive enzalutamide (160 mg) daily plus leuprolide every 12 weeks (combination group), placebo plus leuprolide (leuprolide-alone group), or enzalutamide monotherapy (monotherapy group). The primary end point was metastasis-free survival, as assessed by blinded independent central review, in the combination group as compared with the leuprolide-alone group. A key secondary end point was metastasis-free survival in the monotherapy group as compared with the leuprolide-alone group. Other secondary end points were patient-reported outcomes and safety. A total of 1068 patients underwent randomization: 355 were assigned to the combination group, 358 to the leuprolide-alone group, and 355 to the monotherapy group. The patients were followed for a median of 60.7 months. At 5 years, metastasis-free survival was 87.3% (95% confidence interval [CI], 83.0 to 90.6) in the combination group, 71.4% (95% CI, 65.7 to 76.3) in the leuprolide-alone group, and 80.0% (95% CI, 75.0 to 84.1) in the monotherapy group. With respect to metastasis-free survival, enzalutamide plus leuprolide was superior to leuprolide alone (hazard ratio for metastasis or death, 0.42; 95% CI, 0.30 to 0.61; P<0.001); enzalutamide monotherapy was also superior to leuprolide alone (hazard ratio for metastasis or death, 0.63; 95% CI, 0.46 to 0.87; P = 0.005). No new safety signals were observed, with no substantial between-group differences in quality-of-life measures. In patients with prostate cancer with high-risk biochemical recurrence, enzalutamide plus leuprolide was superior to leuprolide alone with respect to metastasis-free survival; enzalutamide monotherapy was also superior to leuprolide alone. The safety profile of enzalutamide was consistent with that shown in previous clinical studies, with no apparent detrimental effect on quality of life.

In a randomized trial involving men with metastatic prostate cancer with a DNA-repair defect, rucaparib was associated with longer progression-free survival than a control medication (11.2 vs. 6.4 months).

In a randomized trial involving men with hypogonadism and preexisting or a risk of cardiovascular disease, testosterone therapy was noninferior to placebo with respect to major adverse cardiac events.

A randomized trial showed noninferiority of stereotactic body radiotherapy to conventionally or moderately hypofractionated radiotherapy in preventing biochemical recurrence in selected men with localized prostate cancer.

After 4 years of the GÖTEBORG-2 trial, MRI-targeted biopsy led to less detection of clinically insignificant prostate cancer than systematic biopsy without compromising the detection of cancer that may affect survival.

In patients with urothelial carcinoma, the addition of nivolumab to platinum-based chemotherapy resulted in longer median overall survival than platinum-based chemotherapy alone (21.7 months vs. 18.9 months).

PSA screening for prostate cancer should involve consideration of benefits and risks. Screening is associated with a small reduction in prostate cancer deaths; risks include overdiagnosis and unnecessary biopsy and treatment.

In this randomized trial, conducted between 1989 and 2022 to compare radical prostatectomy with watchful waiting, radical prostatectomy led to a 48% lower risk of death from prostate cancer and to 2.2 life-years gained.
