Abstract
OBJECTIVE: To find the epidemiology and risk factors of sinonasal tumors and treatment outcomes in squamous cell carcinoma. STUDY DESIGN: An observational study. PLACE AND DURATION OF STUDY: The Institute of Nuclear Medicine and Oncology Lahore (INMOL), Lahore, from May 2016 to March 2017. METHODOLOGY: All histopathologically proven cases of paranasal sinuses and nasal cavity were selected from the hospital record for epidemiological analysis. Survival outcomes of patients with squamous cell histopathology were determined, which is commonly occurring type. Relevant information was obtained from patient record and telephone communication. The data were analysed using SPSS V.20. RESULTS: Sinonasal malignancies are rare, making (n=81) 0.2% of all registered tumors; out of which, 46 (56.7%) had squamous cell histology. Median age was 50.0 years (IQR: 60.7-40.0) with male predominance (1.7:1). Most of patients presented at advanced stage, T3/ T4 in more than two-thirds of cases, and associated with nodal metastasis in 43.5% of squamous cell carcinoma. In patients with squamous cell histology, median disease-free survival was 19.00 months (SE: 1.65, 95% CI, 15.75 - 22.25), median overall survival remained 34.00 months (SE: 1.84, 95% CI, 30.00 - 38.00). Nodal status had significant effect (p<0.001) on survival. Radiotherapy had significant effect on improved survival (p=0.001) and distant metastasis remained negative prognostic factor (p=0.001). Disease stage was also significantly associated with overall survival (Log Rank 0.014). Tumour size, surgery, chemotherapy, and chemoradiotherapy were not significantly associated with survival. Cumulative survival at 1, 2, and 3 years was 87%, 48% and 29%, respectively. CONCLUSION: Sinonasal malignancies are rare, advanced stage is common, and radiotherapy improves overall survival.
