Chemotherapy combined with androgen-deprivation therapy in high-volume metastatic hormone sensitive prostate cancer: a short-term efficacy and safety analysis / 中华外科杂志

ABSTRACT

Objective@#To investigate the short-term efficacy and adverse events of chemotherapy combined with androgen-deprivation therapy in high-volume metastatic hormone sensitive prostate cancer.@*Methods@#From March 2015 to August 2017, 55 patients with high-volume metastatic hormone sensitive prostate cancer were enrolled at Department of Urology, Fudan University Shanghai Cancer Center receiving chemotherapy combined with androgen-deprivation therapy. The age was 65(8) years (M(QR)) (range 46 to 79 years). Patients were enrolled in the study for continuous androgen-deprivation therapy (medical or surgical castration), combined with docetaxel 75 mg/m2 intravenous injection on the first day, repeated every 21 days (6 cycles). Endpoints included overall survival, progression-free survival of prostate cancer, prostate specific antigen (PSA) response rate, and adverse events.@*Results@#The follow-up time was 21.2(11.7) months. The PSA value before chemotherapy was 144.9(415.3) μg/L. The days in patients undergoing androgen deprivation therapy before chemotherapy was 14(23) days. Four patients (7.3%) presented 0 in Eastern Cooperative Oncology Group scoring system and 51 patients(92.7%) presented 1. Thirty-nine patients (70.9%) completed more than 6 cycles of combined chemotherapy, 17 patients (30.9%) showed PSA<0.2 μg/L at 6 months after treatment, and 14 patients (25.5%) showed PSA<0.2 μg/L at 12 months after treatment. Twenty-eight patients (50.9%) had grade 3 to 4 neutropenia and 1 patient (1.8%) developed infectious neutropenia and died. Nausea and vomit occurred in 16 patients (29.1%). Twelve patients (21.8%) underwent dose adjustment due to adverse events in blood system.@*Conclusions@#The short-term effect was confirmed in high-volume metastatic hormone sensitive prostate cancer using chemotherapy combined androgen-deprivation therapy, and the long-term effect remains to be seen. Myelosuppression during chemotherapy requires close attention, and taking timely examination is recommended.
