Abstract
To evaluate the efficacy of multimodal therapy for squamous cell carcinoma of the maxillary sinus, we analyzed 37 patients in our institute between 1997 and 2007. Multimodal therapy included partial maxillectomy to reduce the primary tumor volume and chemoradiation with intraarterial injection via superficial temporal artery and curative operation. We reviewed the cause-specific survival rate and the recurrence rate to inspect efficacy of the therapy. The survival rates were 89% for T3 tumors, 66% for T4a tumors, 29% for T4b tumors. The local recurrence rates were 0% for T3 tumors, 44% for T4a tumors, 67% for T4b tumors. The salvage rates were 43% for T4a tumors, 0% for T4b tumors. The results indicated the need to consider changing the details of the multimodal therapy to improve the treatment results for T4 tumors.
