Abstract
survival in oral mucosa squamous cell carcinoma. analysis of 161 patients introduction: Oral Cancer accounts 3% of all human cancers. Squamous Cell Carcinoma is the most common. nowadays, in Chile and the world, oral cancer is reaching relevance because of its high inciden - ce and low survival rates; most often is squamous cell carcinoma (SCC). aim: We analyzed the five-year survival of 161 patients diagnosed with SCC. Also was studied relationships between survival and gender, age, location, tobacco, alcohol and treatment. methods: Retrospective study among 1989 and 2010. The study population was mainly men gender (59%), average age 64 years and location of the CEC prefera- bly in tongue (37.6%). 54% were well differentiated carcinomas and TnM, the majority corresponding to T2n0M0. Kaplan-Meier curve and Log Rank test were used for survival analysis and to compare them. We determined significant difference when p value < 0.05. results: The overall survival at five years was 46%, the lowest rates were in the male gender, age group 60, floor of mouth, smokers and alcohol consumers. conclusions: Although tobacco and alcohol are factors highly related to the presence of CEC, there was no significant difference between survival and these habits. There were differences between the survival curves for patients treated with surgery associated with radiotherapy in comparison to other treatments.

Summary
Oral Cancer accounts 3% of all human cancers. Squamous Cell Carcinoma is the most common. Introducción: Hoy en día, en Chile y el mundo, el cáncer oral ha tomado mayor importancia por su incidencia y bajos porcentajes de sobrevida, el más frecuente corresponde al Carcinoma Espinocelular (CEC). Cada año se diagnostican en el mundo más de 575.000 casos nuevos, en Chile se estima que la morbilidad por cáncer oral y faríngeo corresponde aproximadamente al 1,6% del total de todos los cánceres[1,2], cifra algo menor a la de Estados Unidos[3]. El propósito de este trabajo es analizar el porcentaje de sobrevida a los cinco años de una muestra de pacientes diagnosticados con Carcinoma Espinoceluarar de mucosa oral (CEC) y observar su relación con ciertas características epidemiológicas
