Prostate Cancer

Early study results show that an artificial intelligence model may help oncologists better stratify patients with prostate cancer into risk groups than existing methods, according to an expert.

During the 2022 Society for Urologic Oncology (SUO) Annual Meeting, an expert from the Baylor College of Medicine, discussed how perceptions around the use of testosterone therapy have evolved for patients with metastatic prostate cancer.

Adding the investigational oral drug BXCL701 to pembrolizumab appears effective in small cell neuroendocrine metastatic castration-resistant prostate cancer, a rare and aggressive disease.

Thus far, findings from 2 trials show that treatment with bipolar androgen therapy is associated with several benefits in patients with castration-resistant prostate cancer, according to an expert from Sidney Kimmel Comprehensive Cancer Center.

Investigators have observed that treatment with bipolar androgen therapy has suppressed at least one oncogene in patients with castration-resistant prostate cancer who derived a response to therapy.

18F-sodium fluoride PET-CT appeared to be a more accurate identifier of bone metastases in patients with breast and prostate cancer than the standard SPECT method.

Olaparib in combination with abiraterone and prednisone or prednisolone alone has been approved as treatment for metastatic castration-resistant prostate cancer in the European Union.

177Lu vipivotide tetraxetan becomes first targeted radioligand treatment approved by the European Commission for prostate-specific membrane antigen–positive metastatic castration-resistant prostate cancer.

At a median follow-up of 17.4 months, half of the enrolled patients with metastatic castration-resistant prostate cancer experienced a decrease in PSA level from baseline following treatment with tazemetostat in combination with abiraterone acetate or enzalutamide.

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.

PSMA-targeting PET ligand 18F-rhPSMA-7.3 yielded high detection rates for patients with recurrent prostate cancer regardless of factors such as PSA levels, PSA doubling time, or Gleason scores, according to Benjamin H. Lowenritt, MD, FACS.

Future focuses following the phase 3 SPOTLIGHT trial will include identifying sites of recurrence and different intensity levels for 18F-rhPSMA-7.3 in suspected recurrent prostate cancer, according to Benjamin H. Lowenritt, MD, FACS.

The goal of the analysis of the phase 3 SPOTLIGHT trial was to evaluate how clinical factors impact 18F-rhPSMA-7.3 detection rates in a population of patients with suspected recurrent prostate cancer, according to Benjamin H. Lowenritt, MD, FACS.

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.

Novel PSMA-targeting PET ligand 18F-rhPSMA-7.3 adds to the recurrent prostate cancer armamentarium, according to Benjamin H. Lowentritt, MD, FACS.

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.
