It is effective in limb preservation and for preserving the function of joints in situations where surgery alone would result in deficits, which is especially important in young patients. Depending on the three major anatomic locations in which they arise, they are classified as: extra-abdominal fibromatosis, abdominal desmoid, occurring typically in women during or following pregnancy; and intra-abdominal fibromatosis, either a pelvic or mesenteric location.

This analysis revealed radiotherapy at recurrence as a significantly worse prognostic factor compared with adjuvant radiotherapy.

The addition of radiotherapy to the treatment concept was a positive prognostic factor in the multivariate analysis.

This might support the hypothesis that with a combined treatment only modest surgical interventions may be needed, thus avoiding disfigurement.

Additionally, radiotherapy alone may serve as a primary therapy and result in minor or no deficits for those patients whose tumours are un-resectable.

Data were reported and analyzed throughout the whole study anonymously using a coding system based on consecutive numbers per patient and per centre.

The median follow-up period was 6 years (range 1 – 44 years), for 4 patients data were insufficient for follow-up.As fibromatoses do not metastasise, surgical radicality is often compromised when weighed against function preservation.It is the ill-defined margins of infiltration along septal planes that lead to recurrences.The resultant loss of ability to degrade beta-catenin and elevated beta-catenin levels promotes fibroblastic proliferation [].In all settings and locations these fibroblastic proliferations are similar: variably cellular, often hypocellular ill-defined fascicles of fibroblasts and myofibroblasts lacking nuclear pleomorphism and showing little mitotic activity [].Pathology slides of all patients were reviewed by an independent pathologist.
