Abstract

Introduction: Sinonasal malignancies (SNMs) are a rare and heterogeneous group of cancers with an incidence of 3%-5% of all head-and-neck tumours. The aim of the present study was to identify the characteristic features of SNMs and to analyze the treatment outcomes and the prognostic factors affecting it.

Materials and methods: A retrospective review of patients with SNM treated at a dedicated cancer center of Pakistan between 2004 and 2018 was carried out. All patients with histologically proven diagnosis of malignancy arising from nasal cavity or paranasal sinuses and being treated with curative intent were included. The medical records of 184 cases were utilized for final analysis. Chi-square test was applied to identify significant differences. Five-year disease-specific survival (DSS) was calculated using Kaplan-Meier curve via log-rank test and comparison was made between squamous and nonsquamous histologies. P ≤0.05 was considered statistically significant.

Results: Squamous cell carcinoma was the most common histopathology (n = 62, 33.7%). 130 (70.7%) patients presented with stage IV disease. Nodal metastasis was seen in 24 (13%) patients. Treatment failure was seen in 96 (52.2%) patients and was significantly associated with tumour size and the overall stage. DSS of patients with squamous cell carcinoma was 29% as compared to 52% for patients with nonsquamous histologies (P = 0.001).

Discussion: SNM is a diverse group of cancers presenting in late stages. A higher rate of treatment failure associated significantly with stage of the disease was identified in our study.

Keywords: Nasal cavity; paranasal sinus neoplasm; paranasal sinuses; squamous cell carcinoma; treatment outcome.
