About

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.

Full description

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.
