Abstract
BACKGROUND: Intraoperative radiotherapy (IORT) can be applied for locally advanced tumors and expected or unavoidable R1 situations combined with surgical resection. The aim is to improve local tumor control and long-term survival. The indications are primary and recurrent intra-abdominal and retroperitoneal tumors. This study aimed to evaluate own data and experiences with IORT combined with surgical visceral resection.Entities:
