Serum miRNA‐21: Elevated levels in patients with metastatic hormone‐refractory prostate cancer and potential predictive factor for the efficacy of docetaxel‐based chemotherapy

Abstract

Serum miR-21 levels are elevated in HRPC patients, especially in those resistant to docetaxel-based chemotherapy. It may be applicable as a marker to indicate the transformation to hormone refractory disease, and a potential predictor for the efficacy of docetaxel-based chemotherapy.
