ABSTRACT:Oral cavity cancers is among the most debilitating and deadly diseases in the world. The recent and accurate data on these conditions are of great importance for a good strategy to fight especially in the third world countries where data are scarce for lack of cancer registered in many countries. The aim of the present study was to evaluate the frequency of oral cavity cancers in patients attending dentistry and maxillofacial surgery service of Kinshasa university hospital in Democratic Republic of the Congo. A cross-sectional descriptive study was conducted from January 2001 to December 2015. The patients were recruited on the basis of oral cancer confirmed histologically during the period of study. Data were collected through survey questionnaire containing socio-demographic variables (sex and age), clinical variables (oral hygiene, lifestyle: alcohol and tobacco, tumor localization and tumor stage) and analyzed by using Microcal Origin 8.5 Pro software. Results revealed that the incidence of oral cancer was low at 1.8%. The male sex was most represented with a sex ratio of 1.8. The average age was 47.8±18.9 years. Alcohol and tobacco association was the main risk factor with 33.3% of cases. The majority of patients had poor oral hygiene (68.1% of cases), and squamous cell carcinoma was more represented 74.7%. The mandible was the main location of oral cancer (60.7% of cases). Most oral cancer cases were diagnosed at the T4NxMx stage (38.4%). Cancer is a real health problem in our environment, and squamous cell carcinoma was the most diagnosed cancer.
