Background: The addition of docetaxel or abiraterone to androgen deprivation therapy (ADT) achieves superior survival outcomes in metastatic hormone-sensitive prostate cancer (mHSPC) in predominantly Western population. We sought to evaluate the treatment outcomes of adding docetaxel or abiraterone to ADT in Indian population.
Methods: We reviewed the medical records of ninety patients with newly diagnosed mHSPC who received treatment between January 2015 and June 2018. Patients received ADT alone or ADT + docetaxel or ADT + abiraterone as initial treatment. Monthly clinical evaluation and prostate-specific antigen (PSA) measurement were done. Outcome measures analyzed included PSA decline <90%, serological complete response (sCR) (PSA <0.2 ng/ml), and progression to CRPC. Outcome variable was compared using Fisher's exact test.
Results: Patients received ADT alone (n = 37) or ADT + docetaxel (n = 31) or ADT + abiraterone (n = 22). The median age was 67.5 years (range, 41–87 years) and the median PSA was 88.5 ng/ml (range, 1.12–4000). PSA decline <90% was seen in 22 (73%), 24 (86%), and 17 (94%) patients in the ADT alone, ADT + docetaxel, and ADT + abiraterone groups. sCR was achieved in 5 (17%), 10 (36%), and 9 (50%) patients in the ADT alone, ADT + docetaxel, and ADT + abiraterone groups. Progression to CRPC was observed in 18 (60%), 11 (39%), and 2 (11%) patients in the ADT alone, ADT + docetaxel, and ADT + abiraterone groups.
Conclusion: The addition of docetaxel or abiraterone to ADT achieves a deeper serological response and reduces progression to CRPC compared to ADT alone in mHSPC patients of Indian origin. Longer follow-up is required to comment on overall survival and also to determine which combination (ADT + docetaxel or ADT + abiraterone) is superior to others, if at all.
