Wang X, et al. - Authors gauged the caveolin-1 expression in prostate cancer tissue and its association with pathological grade, clinical pathologic staging, and preoperative prostate-specific antigen (PSA) levels. They collected the samples from 47 patients with prostate cancer who had received transurethral prostatic resection (TURP) and 20 patients with benign prostatic hyperplasia at the First Affiliated Hospital of Guangxi Medical University. Findings suggested a close relation of caveolin-1 to the pathological grade and clinical stage of prostate cancer after transurethral surgery, and there is a probability of this to be a novel tumor marker for prostate cancer. They did not note an association of the expression of caveolin-1 with preoperative serum PSA levels.
