Desmoid Fibromatosis

The purpose of this study is to closely observe people with desmoid-type fibromatosis over 1 months.

This study gathers health information for the Project: Every Child for younger patients with cancer. Gathering health information over time from younger patients with cancer may help doctors find better methods of treatment and on-going care.

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.

This is a prospective study on the safety and effectiveness of radiofrequency ablation in patients with desmoid tumors. In the study group, all patients after radiofrequency ablation of the tumor after 1 month will be evaluated using MRI and CT studies and, if solid components of the tumor are detected, repeated surgical treatment is performed followed by active monitoring after 1 month. In the absence of a solid component, the effect is estimated by the volume of the necrotic process and monitored in dynamics every 3 months.
