Surgery

I am a surgical oncologist who specializes in caring for people with stomach (gastric) cancer and gastroesophageal junction (GEJ) tumors, sarcomas, and soft-tissue tumors. I also have expertise in treating  patients with tumors of the duodenum, small intestine, adrenal gland, neuroendocrine system, spleen, and lymph nodes. I work primarily at Memorial Sloan Kettering’s Manhattan location but also see patients at Memorial Sloan Kettering Basking Ridge and MSK Monmouth in New Jersey.

My main goal is to provide each patient with the absolute best care for his or her particular disease. I work closely with medical oncologists, radiation oncologists, pathologists, and other medical professionals who specialize in the diagnosis and treatment of patients with gastric/gastroesophageal junction cancer and sarcomas. I feel it’s important, even for experienced surgeons, to constantly improve and expand one’s surgical skills. For me, this has involved early adoption of new laparoscopic and minimally invasive techniques, such as robot-assisted resection of gastric, adrenal, and other intra-abdominal tumors. I’ve performed over 100 minimally invasive robot-assisted procedures using the da Vinci Surgical System, which allows for smaller incisions, more precise operations, and faster recovery. 

I have performed clinical and laboratory research throughout my career and am the author of more than 150 peer-reviewed articles, reviews, and book chapters. Many of these publications describe the treatment and outcome of patients with various sarcomas (e.g. retroperitoneal and pelvic sarcomas, extremity and trunk sarcomas, and angiosarcomas) and gastrointestinal cancers (e.g. gastric adenocarcinoma, hereditary diffuse gastric cancer syndrome, gastrointestinal stromal tumors, and colorectal cancer liver metastases). I am on the editorial board of medical journals, such as the Annals of Surgical Oncology and the Journal of Gastrointestinal Surgery and serve on several national committees, including the American Joint Commission on Cancer Soft Tissue Sarcoma Expert Panel.

I am the principal investigator for a research laboratory that examines the role of tumor blood vessels and cancer stem cells in controlling the growth, spread, and treatment response of gastric cancers and sarcomas. My laboratory is currently funded by an R01 grant from the National Cancer Institute as well as other foundation and society grants. We previously completed a clinical trial examining the role of bevacizumab (Avastin®), a drug that inhibits vascular endothelial growth factor A (VEGF-A), and radiation in the pre-operative treatment of resectable sarcomas. Bevacizumab markedly improved the tumor-killing effects of radiation, and this trial served as the basis for an ongoing multi-institutional trial of VEGF-A inhibition and radiation run by the Children’s Oncology Group and the Radiation Therapy Oncology Group. More recently, we have found that inhibiting cancer stem cells improves the effectiveness of standard chemotherapies, and we are currently developing clinical trials in this area.
