Summary

Desmoid-type fibromatosis is a rare disease of which 7.5-16% have been reported to be related to familial adenomatous polyposis (FAP). We sought to compare the characteristics and treatment of sporadic and FAP-related desmoid-type fibromatoses. The predictors for FAP occurrence among desmoid tumor patients are large tumor size, intra-abdominal location, multiple tumors, and patient's young age. Desmoid-type fibromatosis patients suffer a high recurrence rate, also among those experiencing sporadic tumors, but the risk of death due to the tumor is low. Conversely, desmoid disease represents a substantial cause of death among FAP patients.
