Research

Martin R. Weiser, MD

Our research investigates the natural history, molecular biology, and treatment response of cancers of the rectum and colon with the goal of personalizing therapy to reduce treatment toxicity, increase survival, and improve post-treatment quality of life.  We have built and tested clinical calculators using clinical, pathologic and molecular features to improve prognostication and better understand tumor biology.  Our contributions to advancing our understanding of colorectal cancer biology and improving colorectal cancer treatment include refinement of neoadjuvant chemotherapy with selective use of radiotherapy, identification of constitutive activation of receptor tyrosine kinases, and characterization of drivers of tumor-infiltrating lymphocytes.
