Abstract
Progressive microsatellite changes in replication error positive (RER+) endometrium were used to reconstruct evolutionary stages of nonfamilial adenocarcinoma. RER+ putative endometrial precancers (atypical endometrial hyperplasias) progress to RER+ carcinomas, which retain some of the altered microsatellites acquired in earlier precursor stages. The RER+ phenotype may provide a specific marker for early-stage endometrial neoplasms that cannot be resolved by routine histopathology and may be a useful tool to stratify stages in the evolution of RER+ tumors.
