title: The consensus statement on the locoregional treatment of abdominal sarcomatosis.
abstract: Abdominal sarcomatosis (AS) is a rare condition characterized by soft tissue sarcoma spreading throughout the abdomen, in the absence of extra-abdominal dissemination. Retroperitoneal sarcomas, pelvic sarcomas, particularly uterine leiomyosarcoma, and gastrointestinal stromal tumors (GISTs) most frequently give rise to AS. Systemic chemotherapy is the standard of care for AS from non-GIST sarcomas, but with an essentially palliative aim and major limitations. Innovative targeted therapies has deeply affected the natural history of GIST, at least in prolonging significantly survival in responsive patients. In this context, the notion that abdominal spread in the lack of extra-peritoneal lesions may typically occur in a number of patients, along with the dismal prognosis generally carried by AS, has prompted a few centers to perform cytoreductive surgery and perioperative intraperitoneal chemotherapy. To date, the rarity of these presentations makes it difficult to evaluate the clinical results and the role of combined local-regional treatment is still a matter of debate. This article presents the results of a group of experts from around the World trying to achieve a consensus statement in AS comprehensive management. A questionnaire was placed on the website of the 5th International Workshop on Peritoneal Surface Malignancy and the experts voted via internet.
