Gastrointestinal Cancer Team

Enhancing treatment through research

Our multidisciplinary Gastrointestinal Team focuses on all the organs of the digestive system. The team treats cancers of the esophagus, stomach, pancreas, liver, gall bladder, small bowel, colon, rectum and anus. The team also conducts basic and clinical research.

The team includes not only medical oncologists, surgical oncologists and radiation oncologists, but also radiologists, pathologists, basic scientists, epidemiologists and population scientists. 

The advantage of being at a
comprehensive cancer center is
access to our multidisciplinary
tumor teams, NCI- and industry-
sponsored clinical trials, and
board-certified oncologists
employing the newest cutting-edge
technologies and techniques
for cancer care.

Meet the Gastrointestinal Team

Medical Oncologists

...  treat cancer using chemotherapy, immunotherapy and targeted therapy. They may coordinate treatment with other specialists and oversee clinical trials.

The order in which a patient receives their care matters. The sequence of treatment can greatly help an individual to overcome their cancer and get back to their life. That is why UNM Cancer Center providers work together as a team  to create the treatment plan for each patient.

Radiation Oncologists

... use radiation to kill cancer cells. They manage how much radiation to use and how to apply it to the tumor. Radiation oncologists at the UNM Cancer Center offer sterotactic body radiation, stereotactic radiosurgery and intensity modulated radiation therapy.

Surgical Oncologists

... at the UNM Cancer Center remove advanced cancers from the delicate tissues of the digestive tract. They can perform Whipple procedures, hyperthermic intraperitoneal chemoperfusion (HIPEC) procedures, and other advanced surgical procedures.

Colorectal cancer almost always starts with a small growth called a polyp. Screening procedures like colonoscopies allow us to find and remove polyps, stopping colorectal cancer before it starts.
