Background: Galectins-galactose-specific lectins are involved in various types of cell activities, including apoptosis, cell cycle regulation, inflammation and cell transformation. Galectins are implicated in prostate malignat transformation. It is not known yet if prostate glands with different grade of pathologies are expressing different galectins and if these galectins express different effects on the cell viability.

Context: Because pelvic lymph node (LN)-positive prostate cancer (PCa) is generally considered a regionally metastatic disease, surgery needs to be better defined.

Objective: To review the impact of radical prostatectomy (RP) and pelvic lymph node dissection (PLND), possibly in conjunction with a multimodal approach using local radiotherapy and/or androgen-deprivation therapy (ADT), in LN-positive PCa.

Evidence Acquisition: A systematic Medline search for studies reporting on treatment regimens and outcomes in patients with LN-positive PCa undergoing RP between 1993 and 2012 was performed.

Galactose-specific lectins (Gal-lectins) were isolated from the mitochondrial fraction of prostate post-operational hyperplasic tissue of two diagnoses: benign prostate hyperplasic tissue with low-grade intraepithelial neoplasia (LGPIN) and benign prostate hyperplasic tissue with atypical adenomatous hyperplasia (AAH). They had similar molecular weight and other properties. Effects of these lectins were investigated in vitro model experiments on bovine liver cells mitochondrial properties.

Purpose: Several tumor markers have recently been applied for prostate cancer screening. We analyze the effectiveness of prostate specific antigen (PSA), age specific PSA, PSA velocity, volume adjusted PSA densities, change in PSA level following antibacterial therapy, free-to-total PSA ratio, alpha1-antichymotrypsin bound PSA, alpha2-macroglobulin bound PSA, alpha1-protease inhibitor bound PSA and human glandular kallikrein 2 in detecting prostate cancer.

Materials And Methods: We conducted a review of the literature between September 2000 and February 2001.
