Malignant neoplasms of the sinonasal tract: report of 71 patients and literature review and analysis.
BACKGROUND
The present study aimed to report the characteristics, prognostic factors, and treatment outcomes of 71 cases of malignant neoplasms of the sinonasal tract and literature review and analysis of major report series.


METHODS
Seventy-one consecutive patients diagnosed with primary malignant neoplasm of the sinonasal tract that were treated and followed up at a university hospital between May 2000 and March 2008 were selected for the present study. Thirty-four patients were treated with surgery followed by a combination of chemotherapy and radiotherapy, 15 with surgery alone, 14 with combined radiotherapy and chemotherapy, six with radiotherapy alone, and two with surgery followed by radiotherapy. To find out the major series of related studies over the last 20 years, a literature review of PubMed was performed. In all, we found 42 major series including 8,164 patients with malignant neoplasms of the sinonasal tract.


RESULTS
There were 35 women and 36 men ranging in age from 5 to 80 years, with a median age of 55 years at diagnosis. The primary sites included were paranasal sinuses in 51 and nasal cavity in 20. There were one case of stage I, 20 of stage II, 27 of stage III, and 23 of stage IV. Epithelial tumors constituted 65% of all neoplasms. After a median follow-up of 39 months for surviving patients, 33 patients are alive and without disease, eight are alive with disease, and 30 patients died due to disease. Local recurrence was the most frequent treatment failure. The 5-year disease-free, local control, and overall survival rates were 42.1%, 59.5%, and 54.5%, respectively. On univariate analysis, cervical lymph nodes involvement, primary tumor size, histologic type, response to therapy, and stage of disease were independent prognostic factors for overall survival. In the literature review and by analyzing the data collection from 42 major reported series, the median age was 57 years and male/female ratio was 1.8. Epithelial tumors consisted of 69% of all malignant neoplasms of sinonasal tract and stages III and IV disease constituted 74.7% of all stages. Local recurrence was the dominant treatment failure in nearly all series. Five-year local control and overall survival rates were 56% and 45.5%, respectively.


CONCLUSIONS
In this review and by analyzing the large data collection of recent major reported series, we found that malignant neoplasms of the sinonasal tract tend to present at locally advanced stage, with a high frequency of local failure and a moderate to poor outcome. More effective local treatment for improving the local control and overall survival is needed.
