HIGH-INTENSITY FOCUSED ULTRASOUND FOR TREATMENT OF UNRESECTABLE TUMORS LOCATED IN THE WALLS OF CHEST AND ABDOMEN IN 10 PATIENTS

摘要

Objective: To present our results of high-intensity focused ultrasound (HIFU) treatment in 10 patients with unresectable tumors involved in the walls of chest and abdomen. Methods: Tumors located in the walls of the chest and abdomen in 10 patients were treated by HIFU, including local recurrence of fibrosarcoma in 1 case and local invasion or metastases in 9 cases. All of the 10 patients had received anti-cancer treatments before HIFU, 3 patients were complicated with intercostal neuralgia. Results: Partial responses were obtained in 2 patients, minor response in 1 patient, stable disease in 4, progressive disease in 2 after HIFU treatments. All the intercostal neuralgia in 3 patients was disappeared after HIFU. Bone scan showed that site of rib metastasis before HIFU became normal after HIFU in one patient. Conclusion: Our preliminary results showed that HIFU could get good results for patients with malignant tumors located in the walls of chest and abdomen if they are focal tumors, even if they are complicated with rib metastasis.
