Current Research

Dr. Offit’s BCRF project is conducted jointly with Dr. Mark E. Robson and brings together several studies using next generation sequencing (NGS) of DNA to define causes of inherited breast and ovarian cancer. While BRCA1 and BRCA 2 are the two most commonly mutated genes in breast and ovarian cancer, they explain only a small portion of these cancers that occur at high frequencies in families. Drs. Offit and Robson have joined with BCRF colleagues at the University of Pennsylvania (Dr. Katherine Nathanson) and Mayo Clinic (Dr. Fergus Couch) to sequence the exomes (coding regions within a gene) and whole genomes of women with BRCA negative breast and ovarian cancer. Via weekly conference calls and data exchange with BCRF colleagues, they have forged a working consortium and have recently received a grant from the National Cancer Institute to further this effort. They have also started to analyze inherited genetic changes in triple negative breast cancer and found at least one new and recurring mutation, and will build a larger group of cases over the next three years. They will continue analysis of  inherited as well as tumor associated changes made possible due to advances in genome sequencing technologies. These studies are advancing our understanding of hereditary breast and ovarian cancer and have generated several published papers in the scientific literature bearing on the operational, medical, as well as ethical challenges of "personalized" genomic counseling.


Kenneth Offit is Chief of the Clinical Genetics Service in the Department of Medicine at Memorial Sloan Kettering Cancer Center (MSKCC). He is also Professor of Medicine and Public Health at Weill Medical College of Cornell University, and Vice Chairman of the Program in Prevention, Control and Population Research at MSKCC. He received his AB at Princeton University and his MD and MPH from the Harvard Medical School and the Harvard School of Public Health. He is a member of the American Society for Clinical Investigation. He was awarded an American Cancer Society Career Research Recognition Award and the 2013 ASCO American Cancer Society Award for research in cancer prevention. Dr Offit is a member of the Board of Scientific Counselors of the National Cancer Institute, and of the Evaluation of Genomic Applications in Practice and Prevention working group of the U.S. Centers for Disease Control.

Dr. Offit's research team identified the most common mutation associated with hereditary breast and ovarian cancer in those of Ashkenazi Jewish ancestry. His group also published the first prospective study documenting a decreased risk of breast and ovarian cancer following oophorectomy in women carrying inherited mutations of the BRCA genes, and the first genome wide association study of BRCA2 mutation carriers. Dr Offit's group has discovered or characterized inherited mutations associated with risk of breast, ovarian, colon cancer, non-Hodgkin's lymphoma, and other malignancies. His laboratory currently focuses on utilizing genomic approaches to discover novel mechanisms associated with increased risk for common malignancies, or which modify the risks of known hereditary predispositions.
