Epidemiology and georeferencing of squamous cell carcinoma cases and their relationship with pesticides

Abstract

ObjectiveTo assess the prevalence of epidermoid carcinoma cases, georeference their locations, and seek to correlate them to areas with higher agricultural production and use of pesticides. Methods This was a cross-sectional, descriptive and retrospective study conducted by searching the histopathological reports with confirmed diagnosis of epidermoid carcinoma of the mouth issued from August 2005 to December 2011 by the public oral pathology laboratory of the State of Mato Grosso, Brazil. Data were plotted with the IBM SPSS Statistics software and spatial analysis used the ArcGIS 10.1 software. Results There were a higher number of diagnoses in 2007 (26.6%); 99 cases (75%) of patients were male; 96 cases (72.8%) were patients aged between 41 and 70 years; and the cities of Cuiabá, Várzea Grande and Rondonópolis respectively showed the highest number of occurrences. ConclusionNo relationship was found between the occurrence of cases of epidermoid carcinoma and the municipalities with high agricultural production and pesticide use.
