Neuroendocrine differentiation in prostate cancer – a review
Journal Title: Revista de Medicină Militară - Year 2015, Vol 0, Issue 3
Abstract
Objectives: This review aims to provide practicing clinicians with the most recent knowledge of the biological nature of prostate cancer especially the information regarding neuroendocrine differentiation. Methods: Review of the literature using PubMed search and scientific journal publications. Results: Much progress has been made towards an understanding of the development and progression of prostate cancer. The prostate is a male accessory sex gland which produces a fraction of seminal fluid. The normal human prostate is composed of a stromal compartment (which contains: nerves, fibroblast, smooth muscle cells, macrophages) surrounding glandular acins – epithelial cells. Neuroendocrine cells are one of the epithelial populations in the normal prostate and are believed to provide trophic signals trough the secretion of neuropeptides that diffuse and influence surrounding epithelial cells. Prostate cancer is the most frequently diagnosed malignancy in men. In prostate cancer, neuroendocrine cells can stimulate growth of surrounding prostate adenocarcinoma cells (proliferation of neighboring cancer cells in a paracrine manner by secretion of neuroendocrine products). Neuroendocrine prostate cancer is an aggressive variant of prostate cancer that commonly arises in later stages of castration resistant prostate cancer. The detection of neuroendocrine prostate cancer has clinical implications. These patients are often treated with platinum chemotherapy rather than with androgen receptor targeted therapies. Conclusion: This review shows the need to improve our knowledge regarding diagnostic and treatment methods of the Prostate Cancer, especially cancer cells with neuroendocrine phenotype.
