Microwave coagulation therapy as a local control for advanced clear cell adenocarcinoma of the maxillary sinus

Maxillary sinus carcinomas comprise 80% of tumors of the paranasal sinuses. The majority of maxillary sinus carcinomas are usually locally advanced at diagnosis because their symptoms are nonspecific. Treatment of these tumors has included chemotherapy, radiotherapy and surgery or combination of those therapies. We report here application of microwave coagulation therapy for tumor volume reduction in a patient with advanced clear cell adenocarcinoma of the maxillary sinus. We selected this treatment because the patient also had inoperable hepatocellular carcinoma and lung metastasis. Consequently, better local control and quality of life were obtained with microwave coagulation therapy.
