In an interview with Targeted Oncology, following a tweet chat on prostate cancer, Tian Zhang, MD, discussed the key takeaways from the tweet chat discussion and highlighted both the role of molecular testing and the impact of the recent FDA approvals in prostate cancer.
The FDA has approved olaparib for the treatment of patients with metastatic castration-resistant prostate cancer who have deleterious or suspected deleterious germline or somatic HRR gene mutations and have progressed following prior treatment with a new hormonal agent.
“Although PARP inhibitor treatment has demonstrated radiographic and PSA responses in patients with BRCA alterations (4–8), the data presented here offer compelling evidence that response to PARP inhibitors is limited in men with mCRPC harboring an ATM, CDK1/2, or CHEK2 alteration."
Positive safety and efficacy outcomes were witnessed in the KEYNOTE-365 study , supporting further assessment of the combination of pembrolizumab and enzalutamide in a larger population of patients with metastatic castration resistance prostate cancer.
"Historically, neoadjuvant hormone therapy has been shown to improve pathologic outcomes. Therefore, neoadjuvant androgen deprivation therapy may allow a nerve-sparing surgical approach to increase post-surgical quality-of-life outcomes without compromising oncologic outcomes.”
A significant improvement in overall survival was observed with darolutamide plus androgen deprivation therapy compared with androgen deprivation therapy alone in men with non-metastatic castration-resistant prostate cancer treated in the phase III ARAMIS trial.
