Therapeutic efficacy of regional and systemic chemotherapy in advanced maxillary sinus cancer.

ABSTRACT

BACKGROUND: To compare the efficacy of regional chemotherapy through the superficial temporal artery and systemic chemotherapy in patients with advanced maxillary sinus cancer. METHODS: Nine of 22 patients with over TNM stage III maxillary sinus cancer received regional chemotherapy and 13 received systemically. The change of tumor volume, the degree of response according to the tumor location, and side effects after chemotherapy were analyzed. RESULTS: Tumor volume reduction was significantly higher in the regional than systemic chemotherapy. Tumor response to chemotherapy was greater in regional than systemic chemotherapy in most maxillary sinus wall. The tumor response in anterior, posterior, and lateral wall of maxillary sinus was greater more than two times in the regional than systemic chemotherapy. There were no severe side effects related to regional chemotherapy. CONCLUSION: Regional chemotherapy was superior to systemic chemotherapy regarding tumor volume reduction, especially located in the anterior, posterior, and lateral wall of maxillary sinus.
