Abstract

Purpose

Docetaxel is a standard therapy for patients with castration-resistant prostate cancer (CRPC). However, docetaxel-associated adverse events (AEs) such as febrile neutropenia (FN) can impair quality of life and may become life-threatening. In this study, we clarified the AEs and risk factors associated with FN in clinical settings.

Methods

This study included 37 Japanese patients with CRPC who were treated with 70–75 mg/m2 docetaxel and 10 mg prednisone every 3 or 4 weeks between 2008 and 2012. AEs, risk factors for FN, and the prognostic significance of several clinicopathological factors were analyzed.

Results

Hematological AEs of ≥grade 3 included neutrocytopenia in 36 patients (97.3 %), leukopenia in 24 patients (64.9 %), lymphopenia in 10 patients (27.0 %), and FN in 4 patients (10.8 %). In addition, severe non-hematological AEs included colonic perforation, interstitial pneumonia, and acute respiratory distress syndrome in 1 patient each. Severe lymphopenia was positively associated with the incidence of FN. Low serum albumin and low lymphocyte count were identified as possible pre-treatment risk factors, while severe lymphopenia was identified as a post-treatment risk factor.

Conclusions

Non-hematological AEs as well as substantial hematological AEs were recognized in the Japanese population treated with docetaxel chemotherapy against CRPC. Pre- and post-treatment lymphopenia and pre-treatment serum albumin should be considered in order to minimize the risk of FN when selecting patients with prostate cancer for docetaxel therapy, and when considering dose modifications, and the prophylactic use of granulocyte colony-stimulating factor.
