Purpose: To explore the safety and efficacy of ultrasound hyperthermia combined with chemotherapy and radical operation for advanced oral squamous cell carcinoma (OSCC).
Methods: Nine patients who had definite pathological diagnosis were enrolled in this clinical trail from 2015 to 2016. All patients underwent ultrasound hyperthermia combined with chemotherapy before radical operation. The treatment regime was as follows: Docetaxel and cisplatin (75mg/m2) used on the first day, fluorouracil (750 mg/m2) infused from 1st to 5th day. All patients received 2 cycles of thermo-chemotherapy, the therapeutic temperature was set to be 40-42 degrees centigrade, ultrasound hyperthermia was performed for 40 minutes every other day for 5 times. The therapeutic outcomes were evaluated by observation of clinical tumor regression.
Results: Of the 9 patients, complete response（CR）was seen in 1 case, partial response (PR) was seen in 3 cases, stable disease（SD）was seen in 5 cases. Complications were not severe and tolerable.
Conclusions: Ultrasound hyperthermia combined with chemotherapy (TPF) may improve the therapeutic effect in advanced OSCC without obvious adverse reactions, and the toxicity and side effects are well tolerated.
