Effectiveness of Docetaxel for Metastatic Hormone-sensitive Prostate Cancer in Clinical Practice.

ABSTRACT:

Background

Addition of docetaxel to androgen deprivation therapy (ADT) for the treatment of metastatic hormone-sensitive prostate cancer (mHSPC) has been proved to be effective with an overall survival (OS) benefit in phase III clinical trials. The effectiveness of docetaxel with ADT in the general patient population remains unknown.

Objective

The purpose of this study is to report the clinical experience in mHSPC patients treated with 3rd-weekly docetaxel plus ADT in routine practice at two Danish institutions.

Design setting and participants

A two-center retrospective study including consecutive mHSPC patients treated with 3rd-weekly docetaxel plus ADT was conducted.

Outcome measurements and statistical analysis

Outcomes of interest were OS, and biochemical and clinical progression-free survival.

Results and limitations

A total of 173 consecutive patients with mHSPC who received docetaxel every 3rd week plus ADT between June 2015 and February 2018 were included. Most patients had high-volume disease (85%). All six planned docetaxel cycles were delivered in 149 cases (86%). Of the patients, 106 (61%) were alive at the last follow-up. At a median follow-up of 42 (37.8-58.6) mo, the median OS was 51.6 (41.5-56.3) mo. Castration-resistant prostate cancer (CRPC) developed in 46% within 1 yr, with a median time to CRPC of 15.6 (13.0-18.1) mo. Prostate-specific antigen nadir ≤0.2 ng/l was achieved in 15% of patients after 6 mo of ADT and in 19% after 12 mo.

Conclusions

The effect of docetaxel for mHSPC patients treated in routine practice appears comparable with the overall efficacy reported in the literature. Selection of patients will influence the results in clinical practice and clinical studies.

Patient summary

In this report, we looked at the clinical effectiveness of docetaxel combined with androgen deprivation therapy in men with metastatic hormone-sensitive prostate cancer (mHSPC) in a Danish population. We found the effect of docetaxel treatment for mHSPC in the general population to be comparable with the overall efficacy reported in published studies.
