Cryoablation of Abdominal Wall Desmoid Tumor
ABSTRACT: A 30-year-old woman presented with right abdominal pain. Cross-sectional imaging revealed a 4 x 2-cm desmoid tumor, which increased in size to 5 x 4 cm over the next several months. The patient was subsequently treated with 2 sessions of cryoablation, which resulted in complete tumor response at 1 year. Her treatment course, as well as a review of the related literature, is presented herein.

Case Description
A 30-year-old woman presented with right abdominal pain. Cross-sectional imaging demonstrated a 4 x 2-cm enhancing soft-tissue lesion within the right rectus abdominis muscle (Figure 1). Core biopsy confirmed desmoid tumor. A multidisciplinary work-up was initiated. The patient was not on birth control or hormonal estrogen therapy. Polyps were not found on colonoscopy, excluding Gardner syndrome.
Given the size and extent of the lesion within the abdominal wall, concerns were raised about the prolonged recovery and potential risks of surgical resection and/or radiation. The patient was managed conservatively. Over the next several months, her abdominal pain worsened and follow-up imaging confirmed that the tumor had enlarged to 5 x 4 cm. Medical management was initiated with sorafenib 400 mg PO daily, which decreased the tumor size, returning it to 4 x 2 cm. After 1 year of treatment, sorafenib was discontinued due to the development of multiple drug toxicities including abnormal uterine bleeding and fatigue.
Interventional radiology was consulted to evaluate for locoregional treatment. Given the size of the tumor, 2 sessions of percutaneous cryoablation were planned to cover the entire tumor while minimizing risks of abdominal muscle and skin damage.
In the first cryoablation session (Figure 2), 3 probes were positioned in the inferior portion of the mass under ultrasound guidance, with each probe spaced approximately 1.5 cm apart. An insufflation needle was advanced into the anterior peritoneal cavity and carbon dioxide gas was injected to separate the underlying bowel from the anterior abdominal wall. Three freeze-thaw cycles were performed under ultrasound and computed tomography guidance.
The patient returned 3 months later for a second cryoablation procedure using similar techniques (Figure 3). Treatment was performed on the untreated superior portion of the tumor and additional focused spot treatments were also performed on areas identified as residual tumor along the inferior margin by intraprocedural ultrasound.
After this second and final cryoablation treatment, follow-up abdominal magnetic resonance imaging was performed every 3 months. The 1-year follow-up imaging demonstrated complete tumor response with decreased tumor size without enhancement. The patient’s pain had significantly improved and no longer affected her quality of life.
Discussion
Desmoid tumor, also known as aggressive fibromatosis, is a locally invasive, rare mesenchymal tumor that is categorized as an intermediate fibroblastic tumor by the World Health Organization.1,2 Desmoid tumors account for 3% of soft-tissue tumors.1 They are categorized clinicopathologically into 3 types, with abdominal-wall type the most common.2 The development of a desmoid tumor and consequently its pharmacological treatment is dependent on multiple endocrine and hormonal factors (mainly estrogen receptors).3 Despite the local nonmalignant prognosis, desmoid growth can compress adjacent structures and impair quality of life.4
Management by National Comprehensive Cancer Network (NCCN) guidelines consists initial of conservative measures for asymptomatic patients.3-5 In some asymptomatic patients, spontaneous regression has been reported.6 For symptomatic patients, a multidisciplinary approach is recommended in order to consider multiple treatment options, including surgical resection, radiation, percutaneous thermal ablation, and chemotherapy.5,7
Surgical resection with wide margin is still regarded the first-line treatment; however, local recurrence is common, with a rate of 8%-31% of cases, even with negative surgical margins.8 This high recurrence rate is likely a reflection of the difficulty to distinguish tumor extension along fascial planes.9 Radical resection is often not possible due to high morbidity from resection of surrounding structures. In particular locations, such as mesenchymal desmoids, the mortality rate and high recurrence rate can be as high as 78%.10 External radiation is usually reserved for patients with unresectable tumors or post resection in the event of positive margins or local recurrence.11 Disadvantages of radiation have been reported, with high recurrence rates (mean rate, 25%)11,12 and complications including neuropathy and joint contracture.13 Chemotherapy agents, including tyrosine kinase inhibitors, vinblastine, and methotrexate, can be administered for unresectable or recurrent desmoids, or as an adjunct to surgery.14
More recently, new technologies have advanced innovative methods to achieve symptomatic relief and local tumor control. The most common radiology treatments are high-intensity focused ultrasound (HIFU) ablation and percutaneous thermal ablation.8,15-17 HIFU is a minimally invasive thermal-ablation technique that focuses ultrasound beams to cause coagulative necrosis. Multiple studies demonstrated the efficiency of HIFU in selected patients with desmoid tumors with curative and palliative intent.16 Percutaneous thermal ablation encompasses cryoablation, radiofrequency ablation, and microwave ablation. In one study evaluating efficacy of cryoablation after 1-year follow-up, 89% of patients reported improvement, with complete response rate in 36%, partial response rate in 36%, and stable disease in 28%.17
The minimally invasive nature of percutaneous thermal ablation coupled with advanced imaging techniques provide several advantages over surgical resection. Treatments are generally well tolerated. Procedures can be performed with moderate to deep sedation and can be performed as outpatient procedures or with only minimal (1- to 2-night) hospitalization stays. Postprocedure scarring is minimal compared with surgical resection. Complications of ablation are similar to surgery and radiation, and include collateral damage to adjacent structures and recurrence. While the treatment is very effective when performed technically well, evaluation for nearby functional nerves and hollow organs is critical during patient selection. Techniques to isolate the ablation zone from these critical structures, such as presented in the case herein, should be considered to minimize the risk of complications.
While the technology is relatively nascent, the growing body of literature for percutaneous thermal ablation is compelling and bolsters this treatment option in the multidisciplinary management of desmoid tumors.
