Objectives: The purpose of this study was to analyze the incidence and epidemiological profile of oral and oropharyngeal cancer cases, diagnosed in Oral Pathology Services located in Mato Grosso State, between January, 2000, and December, 2005. Methods: This was a quantitative, documented, descriptive, and longitudinal study. The focal point of the study was the histopathologic findings reported by oral pathologists in the Pathologic Anatomy Service of Mato Grosso State Laboratory (MT Laboratory) and at the General University Hospital (HGU) of the CuiabŠ City, capital of Mato Grosso State. We first verified 4672 histopathology findings, and subsequently confirmed the number oral and oropharyngeal cancer cases. The lip cancer cases were considered like oral cancer. The following incidence and variables were analyzed: histological specification, site of the primary tumor, gender, age, skin color, and patient origin (urban or rural). After data collection and tabulation, statistical analysis was performed. Results: From among the 4672 histological findings, 128 (2.7%) were lesions with confirmed diagnosis of oral and oropharyngeal cancer. Among these 128 cases, 119 (92.9%) were oral cases and nine (6.0%) were oropharyngeal cases. In terms of incidence, oral and oropharyngeal cases increased from 2002, with a peak in 2004, and decreased in 2005. The most frequent histological specification was squamous cell carcinoma, and the tongue was the primary disease site. The majority of diagnoses were in males from 40 to 50 yrs of age, with white skin, and living in Mato Grosso State. Conclusions: Considerable numbers of oral and oropharyngeal cancer cases exist in Mato Grosso State. The epidemiological profile of this region suggests the necessity of specific prevention programs for the early diagnosis of oral and oropharyngeal cancer.
