Research Interests -
Clinico-pathologic and molecular genetic aspects of the adenoma-carcinoma sequence in colorectal neoplasia have been a long term interest. Current studies in collaboration with Dr Shi Yang are focused on the role of methylation of CpG islands of the promoter regions of suppressor and mutator genes in the progression of serrated polyps to colorectal cancer in susceptible individuals. We are also pursuing studies, in collaboration with other scientists in the department, of basic molecular mechanisms, particularly activation of the RAS-RAF-MAP kinase signaling pathway, that may underlie hyperplastic polyp persistence, regression or progression to adenoma. In collaboration with Dr.s Sidney Winawer and Ann Zauber of MSKCC, New York, I have a continued interest in the analysis of the National Polyp Study pathology and clinical database in the context of new insights into colorectal cancer evolution that have been gained since the completion of this landmark clinical trial over a decade ago. I am also involved, as PI of the Pathology Review Center , with a new national clinical trial based at MSKCC, New York that is designed to evaluate the efficacy of a single screening colonoscopy in colorectal cancer prevention.
