Description of Research Interests/Activities

Dr. Staszewski is the recipient of a $75,000 per year New York State ECRIP award for 2009-2011. The project centers around developing our expertise in assaying for microsatellite instability testing and DNA mismatch repair enzyme expression in tumor tissue from younger subjects with colorectal and endometrial cancer to estimate the local risk for HNPCC (Lynch Syndrome). This will be followed by a prospective study of all colorectal/endometrial tumors presenting at any age tested in a similar fashion with confirmatory genetic testing.

Dr. Staszewski is the principal investigator for a number of ongoing clinical trials in breast cancer, leukemia, myelodysplastic syndrome, myeloma, and colorectal cancers. He intends to direct subspecialty focus in genito-urinary, GI, and breast malignancies with the intention of developing clinical research components in each of the areas. Another major interest is the collaboration with Research Staff and the Pathology Department on the acquisition of cutting edge molecular diagnostic technology to to help bring personalized medicine and biomarker research from the bench to the bedside.
