Prostate Cancer

Based on data showing that patients with metastatic castration-resistant prostate cancer may achieve benefit following treatment with olaparib plus abiraterone and prednisone or prednisolone regardless of homologous recombination repair mutational status, the FDA gave the combination priority review.

Ian D. Davis, MBBS, PhD, spoke about the subgroup analysis of the ENZAMET trial which analyzed enzalutamide in metastatic hormone-sensitive prostate cancer.

Shared insight on the frontline use of chemotherapy options for patients with metastatic CSPC in the context of AR-targeted therapies.

After reviewing a patient scenario of metastatic castration-sensitive prostate cancer, expert panelists break down frontline treatment options in this setting.

Patients with metastatic hormone-sensitive prostate cancer can now receive treatment with oral darolutamide plus docetaxel following its approval by the FDA.

Data from a substudy of the phase 3 VISION trial presented at 2022 ASCO Annual Meeting showed that higher standard mean uptake value by PSMA-PET is strongly associated with outcomes for patients with metastatic castration-resistant prostate cancer.

Results from the phase 3 KEYNOTE-921 trial showed the primary end points of overall survival and radiographic progression-free survival were not met despite a trend towards improvement following treatment with pembrolizumab and docetaxel in patients with metastatic castration-resistant prostate cancer.

Ian D. Davis, MBBS, PhD, spoke about updated survival results of the ENZAMET trial which analyzed enzalutamide in metastatic hormone-sensitive prostate cancer.

Radical proctectomy, external beam radiotherapy, and brachytherapy yielded comparable prostate cancer–specific mortality, while external beam radiotherapy with or without brachytherapy resulted in favorable distant metastases outcomes in patients with high-risk prostate cancer.

At 24 months of follow-up, MRI-guided focused ultrasound focal therapy was found to be safe and effective for patients with grade group 2 or 3 prostate cancer.

Enzalutamide monotherapy could be a promising alternative to active surveillance for patients with low- and intermediate-risk localized prostate cancer.

Metastatic castration-resistant prostate cancer tumors can be classified as luminal and basal, possibly allowing for a better precision medicine approach to treatment.

Patients with high-risk prostate cancer appeared to derive benefit from androgen deprivation therapy given for a minimal duration of over 18 months plus external beam radiotherapy.

Treatment with 177Lu-PSMA-617 resulted in poor outcomes for patients with metastatic castration-resistant prostate cancer whose tumors had little to no prostate-specific membrane antigen expression.

Data from the SPOTLIGHT trial indicate agreement among trained PET readers was highly concordant with use of 18F-rhPSMA-7.3 imaging for recurrent prostate cancer.

The radiotherapy schedules used in the ATLAS trial reflect recent evidence and guideline changes for its usage in patients with high-risk localized or locally advanced prostate cancer.

Results from the phase 3 SPOTLIGHT trial showed 18F-rhPSMA-7.3 increased post-scan disease upstaging in recurrent prostate cancer.

Metastatic progression pattern with darolutamide appears to be unaltered in nonmetastatic castration-resistant prostate cancer, despite the agent resulting in better survival outcomes.

A post-hoc analysis of the phase 3 TITAN trial revealed potential biomarkers that may predict overall survival in patients with metastatic castration-resistant prostate cancer receiving apalutamide plus androgen deprivation therapy.

Unlike with enzalutamide, it appears darolutamide does not affect systemic exposure of cabazitaxel in patients with metastatic castration-resistant prostate cancer.

Data presented at 2022 ASCO reveals PET-imaging characteristics linked with 177Lu-PSMA-617 efficacy in metastatic castration-resistant prostate cancer.

Results of the ENZAMET trial presented at 2022 ASCO continue to support use of enzalutamide in patients with metastatic hormone-sensitive prostate cancer.

Similar overall survival, better patient-reported outcomes, and fewer adverse effects were observed when patients were treated with 177Lu-PSMA-617 vs cabazitaxel in metastatic castration-resistant prostate cancer.

Adverse effects were found to be similar between patients with metastatic hormone-sensitive prostate cancer who were treated with darolutamide plus androgen deprivation therapy and docetaxel vs androgen deprivation therapy and docetaxel alone.

Three year follow-up findings from a post hoc analysis of the phase 3 ARAMIS trial indicated that darolutamide maintained a survival benefit regardless of prior local therapy for patients with nonmetastatic castration-resistant prostate cancer.

Adding niraparib to abiraterone acetate and prednisone improved efficacy and yielded tolerable safety for patients with metastatic castration-resistant prostate cancer with homologous recombination repair gene alterations.

Expert panelists center discussion around two patient cases to review use of newer anti-androgen deprivation therapy in the management of prostate cancer.

Findings from the phase 3 ARCHES trial highlighted a long-lasting survival improvement for patients with metastatic hormone-sensitive prostate cancer who were treated with enzalutamide plus androgen deprivation therapy regardless of whether they received prior local therapy.

Mark T. Fleming, MD, spoke about how use of 18F-rhPSMA-7.3 for PET/CT scans in patients with recurrent prostate cancer bests conventional imaging.

Results from a phase 3 trial indicated that olaparib yielded better-preserved health-related quality of life and reduced pain burden vs the control for patients with homologous recombination repair gene–altered metastatic castration-resistant prostate cancer who progressed following a prior next-generation hormonal drug.
