Aggressive fibromatosis, also known as desmoid fibromatosis or desmoid tumor, is a fibrous tumor that occurs in the fascia, aponeurosis, or deep soft tissue and is formed by excessive proliferation of fibroblasts and myofibroblasts. At present, the disease is considered to be a borderline tumor. Due to the unclear boundary of the tumor, it often grows into the surrounding adjacent tissues, which is difficult to remove completely and easy to relapse. It has been reported that nuclear β-catenin expression and CTNNB1 gene mutation can be used for the differential diagnosis of aggressive fibromatosis from other spindle cell lesions. At present, there is a lack of multicenter retrospective clinical study of this disease, and there is no literature report on the postoperative quality of life of this kind of patients. This study intends to further explore the clinicopathological features, prognosis and molecular typing of abdominal wall aggressive fibroma by retrospective analysis of the case data of multiple hospitals, as well as sequencing analysis of the retained specimens and paraffin specimens from previous operations, to study the high risk factors for recurrence of the disease, and to further comprehensively analyze the impact of abdominal wall aggressive fibroma surgery on the quality of life of patients through follow-up.
