[Squamous cell carcinoma of naso-ethmoid sinus: Analysis of 146 cases].

ABSTRACT

OBJECTIVE: To evaluate the treatment outcome of different therapeutic modalities for squamous cell carcinoma of the nose and ethmoid sinus and prognostic factors. METHODS: One hundred and forty-six cases of squamous cell carcinoma of the nose and ethmoid sinus treated from 1990 to 2007 were reviewed. Of the 146 cases, 28 were at stage I or II; 46 stage III; 72 stage IV. Forty-one patients were treated with preoperative radiation plus surgery (R + S), 22 patients with surgery plus postoperative radiation (S + R), 5 patients with surgery alone (SA), 78 patients with radiotherapy alone (RA). RESULTS: The overall 5 year survival rate of 146 patients with squamous cell carcinoma of the nose and ethmoid sinus was 49.1%. The 5 year survival rate of the patients at stage I and II was 95.7%, while the rate was 59.8% in the patients at stage III and 28.2% in the patients at stage IV (χ(2) = 24.15, P < 0.05). The 5 year survival rate was 57.7% in R + S group, 60.4% in S + R group, 100% in SA group, and 38.8% in RA group, respectively (P > 0.05). The 5 years survival rate of N+ patients was lower than that of N0 (χ(2) = 12.326, P < 0.05). Local recurrence and distant metastasis were main causes of death. Cox analysis showed TNM stage and differentiation of tumor were independent significant prognostic factors. CONCLUSIONS: The higher survival rate of patients with squamous cell carcinoma of the nose and ethmoid sinus was obtained from combined therapy R + S or S + R. SA gave ideal results for early lesions (stage I and II).
