Desmoid fibromatosis (DF) is a rare locally aggressive soft tissue tumour that is characterized as benign as it cannot metastasize. It was managed until recently like sarcomas, that is, with radical surgical resection combined or not with radiotherapy. However, this approach was associated with a high rate of recurrence and significant morbidity. The management of this disease has progressively changed to a more conservative approach given the fact that DF may spontaneously stop to grow or even shrink in more than half of the cases. Should treatment be required, recent guidelines recommend choosing between systemic therapies, which include principally chemotherapy and tyrosine kinase inhibitors, and local treatments. And this is where the interventional radiologist may have an important role in treating the disease. Various ablation modalities have been reported in the literature to treat DF, notably high-intensity focused ultrasound and cryoablation. Results are promising and cryoablation is now mentioned in recent guidelines. The interventional radiologist should nevertheless apprehend the disease in its globality to understand the place of percutaneous treatments among the other therapeutic options. The goal of this review is therefore to present and discuss the role of interventional radiology in the management of DF.

Solid organ tumors present a significant healthcare challenge, both economically and logistically, due to their high incidence and treatment complexity. In 2023, out of the 1.9 million new cancer cases in the United States, over 73% were solid organ tumors. Ablative therapies offer minimally invasive solutions for malignant tissue destruction in situ, often with reduced cost and morbidity compared to surgical resection. This review examines the current Food and Drug Administration-approved locoregional ablative therapies (radiofrequency, microwave, cryogenic, high-intensity focused ultrasound, histotripsy) and their evolving role in cancer care. Data were collected through a comprehensive survey of the PubMed-indexed literature on tumor ablation techniques, their clinical indications, and outcomes. Over time, emerging clinical data will help establish these therapies as the standard of care in solid organ tumor treatment, supported by improved long-term outcomes and progression-free survival.

Desmoid tumors (DTs) are rare fibroblastic proliferations, characterized by infiltrative growth and a propensity for local recurrence. Traditional strategies such as surgery, radiotherapy, and chemotherapy are the mainstays of treatment, each with its limitations and associated risks. The trend in DT management leans toward a "wait-and-see" strategy, emphasizing active surveillance supported by continuous MRI monitoring. This approach acknowledges the unpredictable nature of the disease, and a multidisciplinary management of DT requires a nuanced approach, integrating traditional therapies with emerging interventional techniques. This review highlights the emerging role of minimally invasive interventional radiological technologies and discusses interventional radiology techniques, including chemical, radiofrequency, microwave, cryoablation, and high-intensity focused ultrasound ablations as well as transarterial embolization.
