The recent 2022 ASCO GU Cancers Symposium provided important new data for the management of advanced prostate cancer. Presentations covered in this review of symposia highlights include androgen receptor (AR) inhibitors in patients with metastatic hormone-sensitive prostate cancer, combinations of PARP inhibitors with abiraterone acetate in metastatic castration-resistant prostate cancer, 177Lu-PSMA-617 in metastatic CRPC, some novel therapies, and even a look at an artificial intelligence pathology predictive biomarker.

Illucix is a preparation kit for gallium-68 PSMA-11 injection, an agent indicated for PET PSMA position tumors in patients with suspected prostate cancer metastasis who are eligible for initial definitive therapy and have suspected cancer recurrence based on elevated PSA levels.

From JAMA Network Open comes this conclusion: “In this study, the benefit associated with olaparib was reduced, eliminated, or inferior in specific subgroups of patients when treatment outcomes were compared with a more active standard of care, ie, cabazitaxel. While treatment with olaparib was associated with superior rPFS in patients with BRCA1/2 variants, those with other HRR variants may have worse outcomes with this approach, which should be reassessed by national guidelines. Numerous active studies…will add to the data regarding the role of PARP inhibitors in mCRPC.”

Directly from this Journal of Clinical Oncology Original Report: “Among men randomly assigned to receive ADT + RT + docetaxel versus ADT + RT, significantly less RT-induced cancers were observed. The treatment effect of adding docetaxel to ADT + RT on overall survival in men with a prostate-specific antigen (PSA) < 4 ng/mL was driven by the absence of PC death, providing evidence to support a distinct biology in low PSA-producing, unfavorable-risk PC that is docetaxel-sensitive.”

In this clinical trial, the authors attempt to answer the question of whether a high-intensity interval training program can improve cardiorespiratory fitness and delay the biochemical progression of prostate cancer in patients who are undergoing active surveillance. One group was asked to complete 12 weeks of thrice-weekly, supervised aerobic sessions on a treadmill at 85% to 95% of peak oxygen consumption (V̇o2). The usual care group maintained their normal exercise levels.

Bowing to criticism from doctors, the National Comprehensive Cancer Network (NCCN) has again updated its guidelines for prostate cancer. The previous update, released this past September, had changed the recommendation about active surveillance for low-risk prostate cancer to state that active surveillance was no longer the “preferred” management option for patients with low-risk prostate cancer and a life expectancy of 10 years or more. Many physicians criticized this change, saying it could lead to overtreatment of low-risk patients by implying that active surveillance, surgery, and radiation are equivalent management options. As a result, NCCN has further revised its guidelines to now state that active surveillance is preferred for most patients with low-risk prostate cancer and a life expectancy of 10 years or more.
