ABSTRACT
PURPOSE: A retrospective analysis was performed to investigate the proper management of maxillary sinus carcinoma. MATERIALS AND METHODS: Authors analysed 33 patients of squamous cell carcinoma of maxillary sinus treated at Chonnam University Hospital from January 1986 to December 1992. There were 24 men and 9 women with median age of 55 years. According to AJCC TNM system of 1988, a patient of T2, 10 patients of T3 and 22 patients of T4 were available, respectively. Cervical lymph node metastases was observed in 5 patients(N1;4/33, N2b;1/33). Patients were classified as 3 groups according to management method. The first group, named as "FAR" (16 patients), was consisted of preoperative intra-arterial chemotherapy with5-fluorouracil(5-FU;mean of total dosage;3078mg) through the superficial temporal artery with concurrent radiation(mean dose delivered;3433cGy, daily 180-200cGy) and vitamin A(50,000 IU daily), and followed by total maxillectomy and postoperative radiation therapy(mean dose;2351cGy). The second group, named as "SR"(7 patients), was consisted of total maxillectomy followed by postoperative radiation therapy(mean dose 5920 cGy). Her third group, named as "R"(6 patients), was treated with radiation alone(mean dose;7164cGy). Kaplan-Meier product limit method was used for survival analysis and Mantel-Cox test was performed for significance of survival difference between two groups. RESULTS: Local recurrence free survival rate in the end of 2 year was 100%, 5-% and 0% in FAR, SR and R group, repectively. Disease free survival rate in 2 years was 88.9%, 40% and 50% in Far, SR and R group, respectively. There were statistically significant difference between FAR and SR or FAR and R group in their local recurrence free, disease free and overall survival rates. But diffeence of each survival rate between SR and R group was not significant. CONCLUSION: In this study FAR group revealed better results that SR or R group. In the future prospective randomized study is in need.
