Sobrevida de pacientes com carcinoma espinocelular bucal em Campina Grande, Paraíba

Abstract

The oral cancer is considered one of the malign tumors which most attack the human being and the patients’ survival is still considered low despite the scientific and technological advances regarding the diagnosis methods and treatment. It was estimated in this work a global and accumulated survival rate in patients with oral CEC in the period of five years, treated in an Oncology Reference Center, Campina Grande/PB, from 2002 to 2006, considering the possible prognostic indicators. A Kaplan-Meier analysis was used and it was possible to obtain survival curves for each one of the categorical variables whose differences were analyzed using the Log-Rank test and the Wilcoxon (Breslow) test, with a significant level of 5%. Men, the tongue and the left side of the anatomical areas were the most attacked by CEC. Most of the patients were diagnosed as being in a tumor advanced stage (III and IV) in the mouth who presented a shorter survival. The global survival was 57% being found a bigger rate of death in the patients with oral cancer. The cancer stages represented an important prognostic factor directly interfering in the accumulated survival from the first year of evaluation. The patients with CEC present a low global survival being the cancer stages the only variable considered as a prognostic indicator.
