Sporadic aggressive fibromatosis has a high tendency for local recurrence, even after apparently adequate resection. Subscribe to Table of Contents Alerts. Abdominal fibromatosis Extension into adjacent muscle. Eur J Cardiothorac Surg. Desmoid tumors can either be primitive or secondary to trauma, including surgical procedures, or hormonal stimulation. There are ongoing studies evaluating the effectiveness of pre-operative radiotherapy in reducing the dimensions of the tumors and in affecting the risk of local recurrence Multimodality management of desmoid tumors: The tumor cells are uniform and lack mitotic activity.


Fibromatosis and Desmoid Tumors

Possible risk factors sxtraabdominal the development of desmoid tumors include female sex, or a previous history of surgery, trauma, or pregnancy. However, surgery, radiotherapy, or both are regarded as the treatment s of choice for lesions [ 3 ].

In conclusion, the present study determined that radical resection with margins free of disease still remains the optimal treatment strategy for patients with extra-abdominal fibromatosis.

A distinctive histopathology has been demonstrated in desmoid tumors of young FAP patients, whose first manifestation of the condition was often this lesion. Interferon has been shown to be effective in increasing the period of disease-free survival in certain patients 1. This “non-aggressive” protocol was applied on a larger multi-institutional series of patients 9 and its implementation avoided aggressive surgery or radiotherapy on the majority of primary tumours.
