Columbia’s Division of Surgical Oncology is dedicated to leading the field of cancer surgery through top-quality clinical care, academic excellence, and pioneering research.

Patient Care

Columbia’s Division of Surgical Oncology offers patients a comprehensive and multidisciplinary approach to the diagnosis, treatment, prevention, and recovery from sarcoma, gastrointestinal stromal tumors (GISTs), other soft tissue tumors, stomach and gastroesophageal junction cancer, other gastrointestinal tumors, melanoma, neuroendocrine tumors, spleen tumors, and lymphoma. We bring our patients the full range of surgical procedures and techniques, and as part of Columbia’s Herbert Irving Comprehensive Cancer Center, we also offer a collection of nonsurgical programs designed to help guide and support our patients through every step of their diagnosis, treatment, and recovery.

Through research and clinical trials, we are continually seeking to advance the science of cancer care. This allows us to gain a better understanding of these disease so that we can develop safer and more effective treatments.

Stand Up To Cancer

Surgeons and scientists in Columbia’s Department of Surgery are advancing efforts for early detection of gastric cancer for tomorrow's patients, while providing the best possible care for today's patients. A team of Columbia’s researchers and physicians, co-led by Sandra Ryeom, Ph.D., Associate Professor in the Division of Surgical Sciences and including Dr. Sam Yoon, Chief of the Division of Surgical Oncology and an international, interdisciplinary team of experts in gastric cancer, advanced imaging, & molecular biomarkers were recently awarded a $3 million Stand Up To Cancer (SU2C) grant (https://standuptocancer.org/research/research-portfolio/research-teams/gastric-cancer-interception-research-team/) to analyze novel diagnostic tests that can detect gastric cancer earlier than current modalities.
