Socio-demographic factors in the prognosis of oral cancer patients

The aim of this study was to determine the survival rate of oral cancer patients treated in a medical center in central Taiwan and to investigate whether socio-demographic factors influence their survival. We retrospectively reviewed 1010 chart records of oral cancer patients. Survival was analyzed by the Kaplan-Meier method and Cox proportional hazard model was used for investigating the relationship between socio-demographic factors and survival. The overall 5-year survival rate was 63.24%. Multivariate analysis revealed that those without religious belief tended to have higher probability of death than those who had religious belief (relative risk (RR): 2.057, p < 0.001). In addition, those who were single, widow/widower or divorced/separated had a poorer prognosis than those who were married (RR: 1.528, p = 0.008). Apart from clinical features, socio-demographic factors also significantly influenced the survival of oral cancer patients. Therefore, care providers should take socio-demographic issues into consideration aside from ordinary clinical health care. (c) 2005 Elsevier Ltd. All rights reserved.
