Daniel E. Spratt, MD, of the University of Michigan Rogel Cancer Center, discusses phase III results of the HERO trial, which suggested benefits of the oral medication relugolix: a substantially faster time to castration with longer duration, fewer cardiac events, and a faster return to normal testosterone levels compared with leuroplide (Abstract 35).
Daniel E. Spratt, MD, of the University of Michigan Rogel Cancer Center, discusses a pooled analysis of two phase III trials showing adjuvant androgen-deprivation therapy (ADT) improves biochemical control and reduces distant metastasis when compared with a neoadjuvant approach, with no difference in late gastrointestinal or genitourinary toxicities. The analysis also showed that delaying radiotherapy to deliver neoadjuvant ADT did not benefit most patients (Abstract 32).
Cynthia Menard, MD, of the University of Montreal, discusses a study on the use of prostate-specific membrane antigen PET and CT to guide treatment. The scans led to high rates of new lesion detection and therefore intensification of radiotherapy for patients with prostate cancer, without an increase in side effects (Abstract 34).

The message still needs to get out that metastatic castration-sensitive prostate cancer should be treated with both androgen-deprivation therapy (ADT) and either docetaxel or an androgen receptor pathway inhibitor. In spite of “overwhelming” support for ADT plus abiraterone/prednisone,...
In a study reported in JAMA Oncology, Dee et al found that radiotherapy (RT) initiated at up to 6 months after the start of androgen-deprivation therapy (ADT) was not associated with poorer overall survival vs initiation before ADT in men with prostate cancer. The investigators observed that these...
Uriya, age 49, visits Israel’s Rabin Medical Center for a cancer screening. On the surface, he shows no signs of disease. However, results from a study by David Margel, MD, PhD, revealed Uriya is living with prostate cancer at an early yet curable stage. Uriya carries the BRCA gene. Rabin Medical...

Androgen-deprivation therapy has been, and remains, the standard of care for patients with metastatic prostate cancer. Patients are often surprised to learn that was all we would do to control their disease and sometimes asked why they would not receive chemotherapy, as for other cancers. I would...
Based on the recently published ENZAMET, ARCHES, and TITAN trials,1-3 we now have several choices of systemic combination therapies for men with metastatic hormone-sensitive prostate cancer.
