ABSTRACT
Objective: The purpose of the study was to identify trends in incidence rates of oral squamous cell carcinoma (OSCC) at specific anatomic sites or within specific age or sex groups in the Western Uttar Pradesh population. Materials and Methods: The study covers the period from January 2004 through April 2009. OSCC cases were retrospectively analysed for site, age, gender and habits and the findings were formulated to chart the trends in Western U.P. Results: The study revealed a male to female ratio of 2.2:1 with the largest number of OSCCs developing in the fourth and fifth decades of life. Overall, the most common site was the buccal mucosa (63.75%), followed by retromolar area (15%), floor of the mouth (11.25%), lateral border of the tongue (3.75%), labial mucosa (3.75%), and palate (2.5%). Smokeless tobacco habit was more prevalent than smoking tobacco in both men as well as women. Karl - Pearson's correlation coefficient was calculated to find the degree of association between the two variables i.e. between gender to buccal mucosa and gender to smokeless and smoking tobacco habits, which were found to be positively correlated with respect to the age. Conclusion: Oral cancer is an important cause of morbidity and mortality worldwide with an incidence rate that varies widely by geographic location. Even within one geographic location, the incidence varies among groups categorized by age, sex, site or habit.

Se estudiaron 55 pacientes con lesiones leucoplásicas en cavidad bucal en edades comprendidas entre 24 y 79 años, pertenecientes a la población de Maracaibo, Estado Zulia, Venezuela. La mayor incidencia de leucoplasia en nuestra investigación estuvo en el grupo etario de 52 a 65 años (34,5 por ciento), siendo la queratosis focal el diagnóstico más común de todas las lesiones lecuoplásicas examinadas 73,8 por ciento, con frecuencia significativa en fumadores. Los sitios más frecuentes de aparición de la lesión fueron paladar duro (27,8 por ciento), mucosa bucal (21,3 por ciento) y reborde alveolar (16,4 por ciento). El 9,8 por ciento de las lesiones examinadas presentaron grado leve o moderado de atipia celular. Al analizar la relación de hábitos, como el fumar, consumo de alcohol y alimentos muy condimentados y/o picantes con la aparición de estas atipias encontramos que la mayor proporción de estas, se presentaban en pacientes con los tres tipos de hábitos
