Socio-demographic factors in the prognosis of oral cancer patients

SummaryThe 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.
