Neoadjuvant HIFU treatment for malignant fibrous histiocytoma: report of a case.
High-intensity focused ultrasound (HIFU) is an innovative, noninvasive, extracorporeal technique that induces coagulative necrosis of tumor tissue by thermal effects and cavitation. In published studies, HIFU has usually been used as an alternative to surgery, with or without other treatment modalities, to achieve curative tumor ablation or palliative tumor cytoreduction. Neoadjuvant HIFU treatment for primary inoperable malignant fibrous histiocytoma has never been reported, and neoadjuvant radiotherapy, chemoradiation, or chemotherapy is routinely under consideration. This is the first case in which HIFU ablation contributed as a neoadjuvant therapy to facilitate function-sparing resection, not as a replacement for surgery. It suggests that HIFU ablation may have some unique major advantages for treating inoperable huge soft-tissue sarcomas as a neoadjuvant local treatment modality, especially for patients for whom neoadjuvant chemotherapy or radiotherapy is not indicated.
