Prostate Cancer

All patients with chemo-naïve metastatic castration-resistant prostate cancer experienced PSA decline, and half the cohort experienced a PSA decline greater than 50% after treatment with a novel PSMA-targeted radionuclide therapy.

Patients with newly diagnosed prostate cancer benefitted from 18F-rHPSMA-7.3 PET when used prior to surgery.

“With more potent agents, can we actually cure patients [with prostate cancer]? I'm not so sure about that…because of heterogeneity,” said an expert from NewYork-Presbyterian – Weill Cornell Medical Center in New York City. “So we'll see. But I think with combinations, maybe someday we're going to be able to get there.”

Theranostics may fill an unmet need for a group of patients with high-risk localized prostate cancer, but more research is needed to identify how oncology providers can integrate it with the standard treatments, according to an expert from the University of Texas MD Anderson Cancer Center.

Patients with advanced prostate cancer benefitted from relugolix vs leuprolide regardless of baseline testosterone level.

Rezvilutamide with androgen-deprivation therapy yielded improved overall survival and radiographic progression-free survival compared with bicalutamide and androgen-deprivation therapy in patients with high-volume metastatic hormone-sensitive prostate cancer.

From shortening treatment duration without compromising efficacy in breast and prostate cancer to improving quality of life, experts share the main takeaways from the 2022 ASTRO Annual Meeting.

The appearance of circulating tumor DNA and androgen receptor aberrations yielded lower overall survival rates for patients with metastatic castration-sensitive prostate cancer during the phase 3 TITAN trial, according to Agarwal, MD.

According to findings from a biomarker analysis of the phase 2 TheraP trial, mean standardized uptake value of PSMA-PET predicted favorable responses to 177Lu-PSMA-617 compared with cabazitaxel in patients with metastatic castration-resistant prostate cancer.

An abbreviated new drug application was granted approval by the FDA for leuprolide acetate injection for patients with advanced prostate cancer.

Quality of life data from the phase 3 ARASENS study highlighted how early treatment intensification with darolutamide plus standard androgen deprivation therapy and docetaxel improved patient-relevant end points compared with placebo in the management of metastatic hormone-sensitive prostate cancer.

At ASTRO 2022, Phuoc Tho Tran, MD, spoke about the potential benefit of combining salvage radiation therapy and enzalutamide vs placebo in patients with high-risk prostate-specific antigen–recurrent prostate cancer after radical prostatectomy.

The addition of metastasis-directed therapy to intermittent hormone therapy appeared to improve survival in patients with oligometastatic prostate cancer, according to early data from the phase 2 EXTEND trial.

Patients with prostate cancer who experienced an increase in prostate-specific antigen level after radical prostatectomy appeared to benefit from a short course of androgen deprivation therapy after post-operative immediate salvage radiotherapy.

Data from the phase 3 SPOTLIGHT trial indicated that 18F-rhPSMA-7.3 PET yielded a positive detection rate in patients with recurrent prostate cancer, and increased along with prostate-specific antigen level.

Based on findings from the phase 3 CABASTY trial, a fixed 16 mg/m2 dose of cabazitaxel every 2 weeks vs 25 mg/m2 every 3 weeks reduced neutropenic complications in elderly patients with mCRPC.

According to findings from the phase 3 PACE-B trial, genitourinary and gastrointestinal toxicities were similar among patients with prostate cancer receiving conventionally fractioned or moderately hypofractionated radiotherapy and stereotactic body radiotherapy.

A meta-analysis found Black men who undergo radiotherapy for localized prostate cancer have better outcomes in terms of biochemical recurrence, distant metastases, and prostate cancer-specific mortality than White men despite presenting with more aggressive disease.

The phase 3 TALAPRO-2 study met the primary end point of radiographic progression-free survival in patients with metastatic castration-resistant prostate cancer with or without homologous recombination repair gene mutations following treatment with a combination of talazoparib and enzalutamide.

Results from the phase 3 TRITON3 trial demonstrated that radiographic progression-free survival was significantly improved when patients with metastatic castration-resistant prostate cancer were treated with rucaparib monotherapy vs physician’s choice.

A recent analysis of data from the phase 3 PEACE-1 study reveals a correlation between 8-month prostate-specific antigen levels and survival outcomes in patients with metastatic castration-sensitive prostate cancer who are treated with systemic therapy regimens that include androgen deprivation therapy.

Results from the phase 3 KEYLYNK-010 study showed that treatment with pembrolizumab and olaparib did not result in a statistically significant improvement in survival despite yielding higher responses compared with novel hormonal agents in patients with previously treated prostate cancer.

A new drug application for 18F-rhPSMA-7.3 was accepted by the FDA to help with diagnostic imaging in prostate cancer.

Before closing out their discussion on novel treatment approaches to metastatic CSPC, expert panelists share hope for further evolution in care.

Expert oncologists review key studies in the metastatic castration-resistant prostate cancer treatment landscape and discuss how evidence can be applied to clinical practice to improve patient outcomes.
