Care Philosophy

This content was provided by Dr. Leslie "I treat the gastrointestinal cancers, which includes colon cancer, stomach cancer, pancreas cancer. We do the medical oncology part and there's also radiation oncology, surgery. So it's kind of a combined effort. There are a lot of different drugs that are available, so patients have better outcomes and we've got a lot of long-term survivors. You know, people say, Isn't it depressing to treat these cancer patients? But a lot of people are cured, especially for colon cancer or anal cancer, rectal cancer. Within 10 to 15 years we're going to take the patient's tumor, analyze all the genes in the tumor and make like a designer treatment for that patient. We're not there yet, but at Rush we're testing for some of those genes already."
