BACKGROUND: Treatment with androgen deprivation therapy (ADT) plus extended hormone therapy (ARTA) is the standard of care for metastatic hormone-sensitive prostate cancer (mHSPC). Recent data of triplet combination therapies of ADT + ARTA (abiraterone/darolutamide) + docetaxel chemotherapy showed a survival advantage for specific mHSPC patient subgroups.
PURPOSE: What treatment response is observed in real-world mHSPC setting using triplet combination therapy and what are the expected side effects?
RESULTS: All patients receiving triplet combination therapy of ADT + ARTA (abiraterone/darolutamide) + docetaxel were included in the current study. A total of 14 patients with a median age of 62 years and 10/14 abiraterone or 4/14 darolutamide therapy could be included. The median PSA before initiation of therapy was 77 ng/ml (IQR 44-150). Overall, 86% of patients had a PSA response > 90% and the median PSA nadir was 0.3 ng/ml. Severe adverse events (grade III) during triplet therapy occurred in two patients (35,7%) with respectively febrile neutropenia 7.1% (1/14) and diarrhea with infection 7.1%. Other low grade adverse events (grade I/II) consisted of polyneuropathy (1/14), mucositis (1/14), xerostomia (1/14), weight loss (1/14) and fatigue (3/14) were detected. Chemotherapy was interrupted in one patient due to adverse events. After a median follow-up of ten months (IQR: 7-17), two patients (14.2%) showed progression to castration resistance.
CONCLUSION: Triplet therapy shows a very good PSA response in clinical practice. Adverse events during therapy are mainly triggered by classical chemotherapy-known side effects.
