Garrett M. Nash, MD, MPH, FACS, FASCRS

About Me

I am a surgeon with specialized training in cancers of the colon, rectum, anus, appendix, and peritoneum. 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, appendiceal, and peritoneal 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 with the primary goal of measuring the efficacy of intraperitoneal chemotherapy for appendix cancer worldwide and the first randomized trial of intraperitoneal chemotherapy for colorectal cancer in the United States.

I have authored papers on a variety of subjects including cytoreductive surgery, intraperitoneal chemotherapy, minimally invasive surgery, sphincter-sparing rectal surgery, mechanisms of tumor progression, and predictors of outcome following surgery.

I have raised over $50,000 to support cancer research at Memorial Sloan Kettering by completing eight races for Fred’s Team —  NYC Half Marathons each year from 2010 through 2014 and  NYC Marathons in 2010, 2011, 2013, and 2014. This November, I will be running in the 2015 NYC Marathon for Fred’s Team.

Clinical Trials

Research is integral to our mission at Memorial Sloan Kettering, and clinical trials help us discover better forms of patient care and treatment. For you, this could mean access to a new therapy or therapy combination. Click to see a list of the trials I’m currently leading.
