Prostate inflammation and its potential impact on prostate cancer: a current review.

Recent studies have identified a role for inflammation in the development and progression of several cancers, such as liver, stomach and the large intestine. Data from several studies has shown correlations between soluble inflammatory mediators, such as cytokines, chemokines and growth factors. However, a direct relationship between inflammation and prostate cancer has yet to be identified. Two major hurdles currently exist which limit the study of this relationship are first that animal models available for studying prostate inflammation are limited, and secondly that relatively little is known about the inflammatory response in the prostate. Here we first review the data demonstrating a correlation between inflammation and prostate cancer as well as review what is currently known about the inflammatory response in the prostate and the impact this inflammation has on the prostate tissue. 2007 Wiley-Liss, Inc.
