A prospective, open label, randomized phase II trial of weekly docetaxel versus weekly vinorelbine as first line chemotherapy in patients with androgen independent prostate cancer.

Purpose: In previous phase I to III studies docetaxel and vinorelbine have shown promising activity in androgen independent prostate cancer. In the present trial we assessed the efficacy and tolerability of single agent low dose docetaxel vs vinorelbine in patients with advanced androgen independent prostate cancer.

Materials And Methods: A total of 40 chemotherapy naive patients with histologically proven androgen independent prostate cancer, adequate androgen ablation, and clinical and/or biochemical progression were randomly assigned to receive either 25 mg/m(2) docetaxel (arm A) or 25 mg/m(2) vinorelbine (arm B) weekly.

Promoter hypermethylation of GSTP1, AR, and 14-3-3sigma in serum of prostate cancer patients and its clinical relevance.

Objective: Hypermethylation of tumor suppressor genes (TSG) is thought to play an important role in tumorigenesis of prostate cancer. The main focus of research was the detection of TSG hypermethylation in cancer tissue. Our aim was to evaluate the feasibility of detection of hypermethylated genes in serum of prostate cancer patients and its correlation with clinicopathological parameters.

Proctitis after external-beam radiotherapy for prostate cancer classified by Vienna Rectoscopy Score and correlated with EORTC/RTOG score for late rectal toxicity: results of a prospective multicenter study of 166 patients.

Purpose: To evaluate the Vienna Rectoscopy Score (VRS) as a feasible and effective tool for detecting and classifying pathologic changes in the rectal mucosa after radiotherapy (RT) for prostate cancer, and, also, to correlate its findings with the European Organization for Research and Treatment of Cancer (EORTC)/Radiation Therapy Oncology Group (RTOG) score for late rectal toxicity.

Methods And Materials: A total of 486 patients with localized prostate cancer underwent external-beam RT up to 70 or 74 Gy within an Austrian-German prospective multicenter trial. In 166 patients, voluntary rectal sigmoidoscopy was performed before and at 12 and/or 24 months after RT.
