Genetic Alterations in Epithelial and Stromal Compartments of Prostate Adenocarcinomas
Abstract
Genetic analyses on prostate cancer has been occurring for over a decade. However, such studies were uniformly performed on the entire tumor without regard to its components despite the fact that a few groups were quite aware of both epithelial and stromal components of tumors, and the cell biology of the tumor "microenvironment" has been described for the last 20 years. Thus, until now, when a genetic alteration, be it intragenic mutation, regional amplification, or deletion manifested by loss of heterozygosity of markers (LOH) is attributed to a prostate cancer, it is unclear if the alteration is actually occurring in the epithelial compartment, the surrounding stromal compartment or both. Our own preliminary data on breast carcinomas demonstrate that LOH proposal proposes to search for genetic alterations in the stroma of prostate cancers and to determine if such alterations can influence clinical outcome. In the almost 2 years, we suffered technical difficulties mainly with the quality of the blocks. In year 3, the PI has accrued 90 non-M1 adenocarcinomas of the prostate. Of these 90, 70 have been subjected to LCM and total genome LOH scanning data available on 50 with the other 20 in various stages of processing and analysis.
