Leptin increases prostate cancer aggressiveness.

Recent studies indicate that adipose tissue and adipocytokines might affect the development of prostate cancer (PCa). Leptin would have a stimulating effect on prostate cancer cells by inducing promotion and progression, whereas adiponectin would have a protective effect. The aim of this study was to determine the relation between body composition, leptin, and adiponectin levels with the prevalence and aggressiveness of PCa in men of Mendoza, Argentina.

[Body mass index and diet affect prostate cancer development].

Introduction: Prostate cancer (CaP) is one of the most important causes of morbidity and mortality in the world. There is evidence that obesity and inadequate eating habits may promote CaP development.

Objective: To analyze and compare the body mass index (BMI) and the food intake, especially fats and antioxidants, among subjects with CaP and those free of disease as a control group.

[Influence of leptin and adiponectin on prostate cancer].

Background: Many studies have investigated the association between obesity, adipose tissue-derived factors (leptin and adiponectin) and prostate cancer (CaP) but the results are still inconsistent.

Methods: The aim of this study was to carry out a comprehensive review of the existing evidence about the role of leptin and adiponectin in prostate carcinogenesis and to provide an overview of it.

Results: Recent evidence suggests that leptin may play a rol in prostate cancer progression, while adiponectin may act as an "antiprostatic cancer" adipokine.
