Washington, DC-based WUSA-TV profiles Penn patient and Maryland resident Jan Eisner, who in 1999 was diagnosed with neuroendocrine cancer. Neuroendocrine tumors run along the endocrine system, and can show up anywhere in the body, and at multiple times. Jan underwent chemotherapy and the removal of her pancreas, and as a result is now diabetic. She's received targeted proton therapy at Penn's Roberts Proton Therapy Center and now travels to Penn regularly for checkups. "There are 2 types of presentations, there's the hereditary associated disease state and those that are called sporadic," says David Metz, MD, professor of Medicine in the department of Gastroenterology, who has worked with Jan for the last several years. "The diagnosis was always very difficult to make because they present in unusual ways," he says, adding that, "as you live with these tumors longer and longer the tumors get bigger and bigger, they grow faster and faster."
