Alicia K. Morgans, MD, MPH, of Dana-Farber Cancer Institute, and Karim Fizazi, MD, of Institut Gustave Roussy, University of Paris-Saclay, discuss findings from the TALAPRO-2 study, which showed that talazoparib plus enzalutamide improved radiographic progression–free survival over standard-of-care enzalutamide as first-line treatment for patients with metastatic castration-resistant prostate cancer and HRR gene alterations. This regimen also delayed the time to deterioration in global health status and quality of life (Abstract 5004).
Alicia K. Morgans, MD, MPH, and Praful Ravi, MRCP, MBBChir, both of Dana-Farber Cancer Institute, discuss an individual patient-data analysis of randomized trials from the ICECAP collaborative. A PSA nadir of ≥ 0.1 ng/mL within 6 months after radiotherapy completion was prognostic for prostate cancer–specific, metastasis-free, and overall survival in patients receiving radiotherapy plus androgen-deprivation therapy for localized prostate cancer. These findings may help identify patients for therapy de-escalation trials (Abstract 5002).

This is Part 3 of Novel Hormonal Therapies for Prostate Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Alicia K. Morgans, Neeraj Agarwal, and David VanderWeele discuss the management of locally advanced high-risk prostate cancer. The patient is a 57-year-old man who presents to his urology with increasing nocturia symptoms. His PSA is 12.4 ng/mL, and an MRI shows a PI-RADS 5 lesion in the right apex concerning for prostate cancer. Biopsy confirms Gleason 4+4 prostate adenocarcinoma, and several retroperitoneal lymph node metastases are revealed on PSMA PET scan. He is found to have a germline BRCA2 mutation, and his team is considering treatment with radiation plus androgen-deprivation therapy, abiraterone acetate, and prednisone per STAMPEDE. The faculty discuss the optimal treatment workup for patients with locally advanced high-risk prostate cancer, the importance of germline genetic testing, the benefits of intensified treatment with ADT plus abiraterone acetate, and the role of gonadotropin-releasing hormone antagonists in improving testosterone recovery and maintaining quality of life.
This is Part 2 of Novel Hormonal Therapies for Prostate Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Alicia K. Morgans, Neeraj Agarwal, and David VanderWeele discuss the management of de novo metastatic hormone-sensitive prostate cancer. The patient is a 74-year-old man who presents to his primary care physician due to worsening back pain. An x-ray reveals an area in T12 concerning for metastatic cancer, and his PSA is found to be 23 ng/mL. He completes staging workup, which demonstrates multifocal bone metastases and metastatic disease in the liver, and he is started on androgen-deprivation therapy (ADT) as initial treatment for his metastatic disease. The faculty discuss ways to reduce the risk of complications from ADT for patients with metastatic hormone-sensitive prostate cancer, the role of intensified treatment with couplet or triplet ADT combinations, and the importance of co-management with primary care or cardiology.
This is Part 1 of Novel Hormonal Therapies for Prostate Cancer, a three-part video roundtable series. Scroll down to watch the other videos from this Roundtable. In this video, Drs. Alicia K. Morgans, Neeraj Agarwal, and David VanderWeele discuss biochemical recurrence in prostate cancer. The patient is a 64-year-old man with a history of localized prostate cancer treated with radical prostatectomy, Gleason 4+4, and positive extracapsular extension and positive right apical margin. Due to high-risk features, he underwent adjuvant radiation therapy. Although his PSA was initially undetectable, it started to increase after 2 years, reaching 12.9 ng/mL. He was negative for evidence of recurrent disease on bone scan, and his testosterone level was normal. The faculty discuss the challenge of timing treatment in the setting of biochemical recurrence. They also highlight the crucial importance of addressing comorbidities, such as metabolic syndrome, through the management of reversible cardiovascular risk factors to better prepare patients starting androgen-deprivation therapy.

Alex K. Bryant, MD, of the University of Michigan, examined Veterans Administration (VA) facilities in which lower prostate-specific antigen (PSA) screening rates were associated with a subsequent increased incidence of metastatic prostate cancer, particularly among men aged 70 and older. From 2008 to 2019, PSA screening rates have declined in the national VA system, data that may be used to inform shared decision-making about the potential benefits of screening for those who wish to reduce their risk of advanced prostate cancer. (Abstract 298).
Rahul Aggarwal, MD, of the University of California, San Francisco, discusses recent data from the PRESTO study, which showed that apalutamide plus androgen-deprivation therapy (ADT) for 12 months significantly prolonged PSA progression-free survival compared with ADT alone in patients with biochemically recurrent prostate cancer. These results provide support for the intensification of ADT in this setting. (Abstract LBA63).
