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.

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 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).

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.

Guiding the beta-emitting isotope lutetium-177 to prostate cancer lesions with the prostate-specific membrane antigen–targeted radioligand 177 Lu-PSMA-617 plus using standard care was compared with standard care in patients with metastatic castration-resistant prostate cancer. The radioligand therapy prolonged progression-free and overall survival. Adverse effects were more common, but quality of life was maintained.

Senescent cells accumulate with age in all tissues. Although senescent cells undergo cell-cycle arrest, these cells remain metabolically active and their secretome — known as the senescence-associated secretory phenotype — is responsible for a systemic pro-inflammatory state, which contributes to an inflammatory microenvironment. Senescent cells can be found in the ageing prostate and the senescence-associated secretory phenotype and can be linked to BPH and prostate cancer. Indeed, a number of signalling pathways provide biological plausibility for the role of senescence in both BPH and prostate cancer, although proving causality is difficult. The theory of senescence as a mechanism for prostate disease has a number of clinical implications and could offer opportunities for targeting in the future.Senescent cells and their secretome — the senescence-associated secretory phenotype (SASP) — cause a systemic pro-inflammatory state, contributing to an inflammatory microenvironment. In this article, the authors discuss the presence of senescent cells and the SASP in the ageing prostate and the evidence for a role of senescence in BPH and prostate cancer, as well as possible therapeutic targeting of these pathways in the future.

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.

Population-based screening showed that men over age 50 with PSA of 3 ng per milliliter or higher and negative MRI results could safely forgo biopsy. Detection of clinically significant cancer among men with positive MRI results who underwent MRI-directed and standard biopsies was similar to that for the standard biopsy group, but the MRI group had fewer findings of clinically insignificant cancers.

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.
