title: Squamous cell carcinoma at maxillary sinus: clinicopathologic data in a single Brazilian institution with review of literature.
abstract: Squamous cell carcinoma arising at maxillary sinus is a rare neoplasm, characterized by aggressive growth pattern and glooming prognosis. There are no studies describing specifically its epidemiology in the South America. The aim of the current paper is to characterize a Brazilian maxillary sinus squamous cell carcinoma sample and to compare such data with others worldwide relevant series. The records of the Brazilian National Cancer Institute (1997-2006) were gathered and plotted. Additionally, an extensive literature review was carry out using electronic database (PUBMED/MEDLINE and LILACS) over a period of 54 years. A descriptive statistics and univariate survival test (log rank) were employed. Maxillary sinus squamous cell carcinoma was the commonest malignancy of sinonasal epithelium found. It affected mainly mid-age white men and most of them were diagnosed at advanced stage. Surgery combined with radiotherapy was the most therapeutic modalities given. The overall mortality rate in our sample was of 65.5%. Overall 1-, 2- and 5-year survival rate was 57.9%, 44.8%, and 17.7%, respectively. Maxillary sinus squamous cell carcinoma is an aggressive tumor normally diagnosed at the advanced stage and most patients present an unfavorable prognosis and reduced survival rate.
