Abstract
BackgroundDesmoid tumors are rare neoplasms that are locally invasive. However, optimal treatment strategies for recurrent desmoid tumors remain controversial. High‐intensity focused ultrasound (HIFU) has been reported as a noninvasive modality for treating recurrent desmoid tumors. However, its efficacy against massive desmoid tumors or those with complex anatomies remains unclear.MethodsWe developed a new therapeutic strategy called low‐power cumulative HIFU and applied it to treat recurrent desmoid tumors.ResultsWe retrospectively collected data from 91 patients with recurrent desmoid tumors who underwent low‐power cumulative HIFU treatment after surgical treatment failure. The mean ablation proportion of the HIFU treatment was 69.5%, and the objective response rate was 47.3%. The 5‐year estimated progression‐free survival rate for these patients was 69.3%.ConclusionLow‐power cumulative HIFU treatment could achieve significant efficacy and long‐term control of recurrent desmoid tumors.
