Desmoid-type fibromatosis: imaging features and course

Area of Science:

• Oncology
• Radiology
• Soft Tissue Pathology

Background:

• Desmoid-type fibromatosis (DF) presents as an infiltrative soft tissue tumor with high local recurrence rates.
• DF exhibits unpredictable behavior, including spontaneous regression, leading to evolving treatment paradigms.
• Active surveillance is increasingly adopted as the primary management strategy for DF.

Purpose of the Study:

• To review and characterize the imaging features of desmoid-type fibromatosis.
• To correlate imaging findings with the clinical course of DF, including regression and postoperative changes.
• To analyze imaging alterations following systemic treatment for DF.

Main Methods:

• Retrospective review of imaging studies in patients diagnosed with DF.
• Analysis of imaging features in cases of spontaneous regression.
• Evaluation of imaging changes in postoperative DF and after systemic therapy.

Main Results:

• Imaging findings associated with spontaneous regression of DF were identified.
• Characteristic postoperative imaging changes were documented.
• Radiological evidence of tumor response to systemic treatments was observed.

Conclusions:

• Imaging plays a crucial role in monitoring the unpredictable course of DF.
• Understanding imaging features aids in managing DF, especially in the context of surveillance and treatment response.
• Radiological assessment is vital for guiding therapeutic decisions and evaluating outcomes in DF.
