Survival after docetaxel for metastatic castration-resistant prostate cancer in a rural health care setting.

Abstract

Introduction: The aim of this study was to evaluate overall survival of men who received systemic therapy with docetaxel for metastatic castration- resistant prostate cancer (MCRPC) in rural Nordland County, Norway. Prognostic factors related to treatment and other variables were evaluated.

Material and methods: Overall, 132 pa- tients were included in this retrospective study covering the years 2009-2022. Uni- and multivariate survival analyses were performed.

Results: In this elderly cohort (median age 72 years), weekly low-dose docetaxel was the preferred regimen (44%). Seventy-three percent were treated in the first line. Only 11 patients (8%) were pre-exposed to docetaxel in the hormone-sensitive phase. Median survival was 14.3 months. Prognostic factors for longer survival included higher hemoglobin, lower lactate dehydrogenase, administration of docetaxel as first-line MCRPC treatment, and use of fewer prescription drugs for comorbidity. Pre-exposure to docetaxel did not play a major role, p = 0.76.

Conclusions: In this rural health care setting, survival after docetaxel was shorter than reported by other groups. Blood test results were confirmed as important prognostic factors. In the present era of evolving treatment sequences, we recommend monitoring of real-world treatment results.
