[Intraoperative radiotherapy of pancreas and stomach cancer].

IORT can be part of an oncologic treatment plan for patients with pancreatic or advanced stomach cancers that can be potentially cured by surgery. When used palliatively IORT can relieve symptoms. Used curatively IORT allows the administration of irradiation boost which complements percutaneous irradiation of the tumor region and the regional lymph nodes. External radiotherapy may also include irradiation of the liver which is performed simultaneously with chemotherapy. IORT also permits the application of oncolytic doses for adenocarcinomas of the upper gastrointestinal tract.
