OBJECTIVE: To study the clinical characters, treatment modalities and prognosis of patients with maxillary squamous cell carcinoma. METHODS: The clinical data of 60 patients with maxillary squamous cell carcinoma treatment between January 1994 and December 2004 were analyzed retrospectively. The patients were treated with three therapy modalities including radiotherapy alone (22 cases), radiotherapy and surgery (R + S, 29 cases) and concurrent chemo-radio-therapy adjuvant surgery (CCR + S, 9 cases). RESULTS: The five year survival rate were 18.2%, 51.7% and 33.3% for patients in the radiotherapy alone group, the R + S group and the CCR + S group, respectively. Patients receiving R + S combined modality therapy had a significantly higher five year survival rate than the patients who were treated radiotherapy alone (χ(2) = 15.62, P < 0.01). The five year survival rate (51.7%) of patients in R + S group was significantly higher than that (33.3%) of patients in CCR + S group (χ(2) = 4.28, P < 0.05), and also higher than that (18.2%) of patients in radiotherapy group (χ(2) = 9.49, P < 0.01). CONCLUSIONS: The combined therapy of radiation and surgery was a good choice of treatment for the patients with maxillary sinus squamous cell carcinoma. The role of concurrent chemo-radiotherapy adjuvant surgery in the treatment of maxillary sinus squamous cell carcinoma needs further to research.
