Alicia K. Morgans, MD, MPH, of Dana-Farber Cancer Institute, and Michael S. Hofman, MBBS, of Peter MacCallum Cancer Centre, University of Melbourne, discuss follow-up results on LuPSMA vs cabazitaxel in patients with metastatic castration-resistant prostate cancer progressing after docetaxel treatment. The findings suggest that LuPSMA is a suitable option for this population, with fewer adverse events, higher response rates, improved patient-reported outcomes, and similar overall survival compared with cabazitaxel (Abstract 5000).

Timothy A. Yap, MBBS, PhD, of The University of Texas MD Anderson Cancer Center, discusses results from the PETRA study, a first-in-class, first-in-human trial of the next-generation PARP1-selective inhibitor AZD5305 in patients with BRCA1/2, PALB2, or RAD51C/D mutations in advanced or metastatic ovarian cancer, HER2-negative breast cancer, pancreatic, or prostate cancer. Target engagement was demonstrated across all dose levels, and antitumor activity was observed in selected tumor and molecular subtypes.
In this video, Drs. Celestia (Tia) Higano, Julie Graff, and Neal Shore discuss the role of prostate-specific membrane antigen (PSMA)-targeted radioligand therapy in the treatment of metastatic castration-resistant prostate cancer. The patient is an 81-year-old man with 13-year history of prostate cancer who had received multiple prior lines of treatment for his metastatic disease, but no prior taxane. After his PSA rose again, he opted to travel abroad for lutetium (Lu-177) PSMA therapy, since he was not eligible for trials in the United States. The faculty discuss the VISION trial and the current and future role of PSMA-targeted radioligand therapy in prostate cancer. Editor’s Note: This video was filmed prior to the FDA approval of Lu-177 PSMA radioligand therapy on March 23, 2022.
This is Part 3 of Updates in Prostate Cancer, a four-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Celestia (Tia) Higano, Julie Graff, and Neal Shore discuss the first-line therapy for BRCA2-mutated metastatic castration-resistant prostate cancer. The patient is a 69-year-old man with new castration-resistant prostate cancer who was previously treated with androgen-deprivation therapy plus docetaxel for metastatic hormone-sensitive prostate cancer and has a known BRCA2 mutation. The faculty discuss their choices for first-line therapy for this patient, reviewing the current NCCN recommendations, the role of PARP inhibitors, and recent data from the PROpel and MAGNITUDE trials.
This is Part 2 of Updates in Prostate Cancer, a four-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Celestia (Tia) Higano, Julie Graff, and Neal Shore discuss doublet and triplet androgen-deprivation therapy options for metastatic prostate cancer. The patient is a 71-year-old man with metastatic prostate cancer, a PSA of 275, and a positive bone scan, who has begun to receive androgen-deprivation therapy. The faculty discuss what, if any, additional therapy they might add to this patient’s treatment regimen, weighing the current doublet and triplet combination options for metastatic hormone-sensitive prostate cancer. They review the results of the recent PEACE-1 and ARASENS trials and emphasize the importance of assessing bone mineral density and of encouraging genetic counseling for these patients.
This is Part 1 of Updates in Prostate Cancer, a four-part video roundtable series. Scroll down to watch the other videos from this Roundtable. �In this video, Drs. Celestia (Tia) Higano, Julie Graff, and Neal Shore discuss the management of metastatic hormone-sensitive prostate cancer in elderly patients. The patient is a fit 88-year-old man with a history of localized prostate cancer who was originally treated with stereotactic body radiation therapy and is reluctant to start androgen-deprivation therapy for his metastatic disease due to the potential side effects. The faculty discuss the importance of counseling patients about side effects of treatment and when to consider androgen-deprivation therapy rather than metastasis-directed therapy alone, reviewing the results of the phase III HERO trial.
As reported in The Lancet Oncology by Zapatero et al, 10-year results of the Spanish phase III DART 01/05 trial did not support the 5-year findings of significantly improved biochemical disease–free, metastasis-free, and overall survival with long-term vs short-term androgen deprivation plus...
