Evaluation of interventionai chemoembolization for the treatment of bone and soft-tissue tumors: a clinical analysis / 介入放射学杂志

ABSTRACT

Objective To assess the clinical value of interventional treatment for bone and soft-tissue tumors. Methods Selective angiography, transcatheter intra-arterial chemotherapy and/or embolization were performed in 28 patients with pathologically-proved bone and soft-tissue tumors. After treatment the clinical response and pathological changes were observed, and the results were analyzed. Results After transcatheter intra-arterial chemotherapy and/or embolization, relieving or even disappearing of the pain was seen in 23 patients, subside of soft-tissue swelling together with regression of the tumor was seen in 19 patients. Twenty-two patients underwent surgical resection of the lesion one week afte.r interventional treatment. Pathologically, cellular degeneration, necrosis and various degrees of liquefaction were demonstrated on the tumor specimen, which were more obvious in patients treated with embolization. Limp-sparing resection was adopted in 66.7% of patients (10/15). Conclusion lnterventional therapy is an effective method for bone and soft-tissue tumors and it is worth popularizing this technique in clinical practice.
