Surgical treatment of extra-abdominal desmoid tumours (aggressive fibromatoses).
Extra-abdominal desmoid tumours (EADT) are benign lesions but difficult to cure because of their infiltrative nature and tendency to recur. Among many treatments recommended in the past, wide excision has been successful, even in difficult cases. We have analyzed retrospectively 41 cases of histologically confirmed EADTs. A total of 98 operations were performed on these patients: 29 wide excisions on 22 patients, 52 intra-lesional excisions with wide margins on 16 patients, and 17 incomplete excisions on 3 patients. One patient, with intra-pelvic lesions, died of a massive haemorrhage 3 days after surgery. Forty patients were followed from between 3 and 29 years. One, who had a multicentric EADT for 21 years, died from the disease. The significant factors concerning local recurrence after wide procedures were an unsatisfactory initial wide local excision, disease affecting 4 or more muscles and the invasive nature of the recurrences. We recommend wide local excision of these tumours in all anatomical areas that allow this procedure. When major nerves and vessels are involved, we recommend an intralesional excision with wide margins in order to preserve limb function. Radiation therapy should be confined to cases in which wide local procedures are not feasible. Overall, 37 of our patients (90%) were cured of the disease, 2 had their disease controlled, and 2 died.
