Desmoid fibromatoses are rare and locally aggressive mesenchymal tumors. The current scientific evidence regarding the efficacy and safety of the treatment of desmoid fibromatosis by arterial embolization is constituted by several retrospective and prospective studies. These studies report promising results through the use of chemoembolization, that is, arterial embolization using particles loaded with chemotherapy.
Instead, the type of treatment we propose would consist of injection of embolizing material without the use of chemotherapy, based on the positive results we have consistently reported over the years on arterial embolization of musculoskeletal tumors.
Desmoid fibromatoses are rare (1-2 cases/million per year) and locally aggressive, characterized histologically by monoclonal myoblasts present in abundant stromal tissue.The current therapeutic strategy has abandoned primary resection, as recurrences after resection are common and often their phenotype is more infiltrative. Nonsurgical approaches remain suboptimal. For asymptomatic disease, current guidelines suggest an initial period of active surveillance.

Doxorubicin is routinely used in the treatment of soft tissue sarcomas and other mesenchymal malignancies. Its use against desmoid fibromatosis is effective but associated with hematologic, gastrointestinal, and cardiac toxicity. Consequently, this drug is reserved for symptomatic, nonresponsive, rapidly growing, or life-threatening fibromatoses.

Patients affected by desmoid fibromatoses eligible to be treated with transarterial embolization
Exclusion Criteria:
Procedure: embolization therapy
Identification of the main vessels afferent to the tumor to be treated. -Selective and super-selective catheterization of pathological arterial branches, responsible for the blood supply to the neoplasm, through the use of micro-catheters. - Injection of embolizing material (hydrogel microspheres) - Control of technical success: the embolization will be followed by diagnostic arteriography that will evaluate the success of the procedure (occlusion of more than 90 percent of the pathologic vasculature).
Reduction of pain (VAS score)
Clinical assessment regarding pain by Visual Analogue Scale (VAS) score (0-100 mm), in which 0 represents no pain, and 100 represents maximum pain imaginable.
Time frame: 1 year
Reduction of antalgic therapy (mg)
Mean reduction in the use of pain medications evaluated in mg of active ingredient taken daily before the treatment and at follow-up.
Time frame: 1 year
Volume reduction in cm³
Reduction of the lesion evaluated with MRI, measuring the diameter of the lesion in cm³.
Time frame: 1 year
Improvement in quality of life (EORTC QLQ-C15-PAL questionnaire)
Clinical assessment regarding quality of life by EORTC QLQ-C15-PAL questionnaire. The questionnaire consists of several scales, covering different aspects related to palliation. The maximum and minimum scores for each scale of the questionnaire can range from 0 to 100. The interpretation of scores depends on the specific scale in the questionnaire, and a higher value may indicate either greater negative impact (e.g., more symptoms or more suffering) or greater positive impact (e.g., better quality of life or less symptomatology).
Time frame: 1 year
Improvement in quality of life (EORTC QLQ - BM22)
Clinical assessment regarding quality of life by EORTC QLQ - BM22 questionnaire. The questionnaire consists of several scales, covering different aspects related to palliation. The maximum and minimum scores for each scale of the questionnaire can range from 0 to 100. The interpretation of scores depends on the specific scale in the questionnaire, and a higher value may indicate either greater negative impact (e.g., more symptoms or more suffering) or greater positive impact (e.g., better quality of life or less symptomatology). The overall assessment requires a detailed analysis of individual scores and related scales.
