Garrett M. Nash, MD, MPH

I am a surgeon with specialized training in cancers of the colon, rectum, anus, and appendix. The focuses of my practice include minimally invasive techniques for colorectal cancer (including laparoscopy, single-incision laparoscopy, and robotic surgery), avoiding colostomy while preserving bowel, bladder, and sexual function, and the management of peritoneal surface malignancies (including pseudomyxoma peritonei and mesothelioma).

My clinical research involves prospective clinical trials of new technology and surgical techniques for advanced colorectal and appendiceal malignancies, as well as optimizing surgical margins and lymph node retrieval for colon and rectal cancers.  I am the primary investigator for the ICARuS Trial (Intraperitoneal Chemotherapy After cytoReductive Surgery). This is a randomized clinical trial investigating the benefit of intraperitoneal chemotherapy for metastatic appendiceal and colorectal cancer.  It will be the first-ever prospective trial of treatment for appendix cancer worldwide and the first randomized trial of intraperitoneal chemotherapy for colorectal cancer in the United States.
