Article Synopsis
  • Prostate cancer is prevalent among men, with metastatic cases leading to higher mortality rates.
  • High levels of Kisspeptin (KISS1) and its receptor (KISS1R) are found in localized prostate tumors compared to advanced stages.
  • The reduced expression of the KISS1-KISS1R system in advanced prostate cancer suggests it could be a potential marker for diagnosis and a target for treatment.

The Ets-related gene fusions are among the most common molecular alterations in prostate cancer (PCa) and are detected in more than 50 % of PCas. Transmembrane protease serine 2 and Ets-related gene fusion (TMPRSS2-ERG) is the most frequently identified chimeric gene and has been associated with undifferentiated and invasive phenotypes. TMPRSS2-ERG has also been detected in prostate intraepithelial neoplasia (PIN) lesions and more rarely in benign prostatic hyperplasia (BPH) regions mainly in PCa-bearing glands.

Background: Radical cystoprostatectomy and radical prostatectomy are the two major operations where prostate is totally and radically removed. Radical cystoprostatectomy is usually performed in patients with invasive bladder cancer. The aim of the study was to examine Total PSA, Free PSA, and Free/Total Ratio elimination kinetics after radical cystoprostatectomy.

Unlabelled: The aim of this study was to elucidate the prognostic value of the immunohistochemical detection of the androgen receptor (AR) status, the chromogranin A assessment of neuroendocrine differentiation (NED) and the CD34 assessment of microvessel density (MVD) with time-to-biochemical failure among surgically treated patients with clinically localized prostate cancer.

Patients And Methods: Surgical specimens from 130 patients with clinically localized prostate cancer, treated with radical prostatectomy, were analyzed by immunohistochemistry on paraffin tissue sections. Full-length follow-up records were available for 94 patients.
