Determining the Prognostic Factors of Survival in Patients with Head and Neck Cancer Using Parametric Models and Cox Bayesian Model, from 2007 to 2013

Head and neck cancer is one of the most important cancers with low survival. This study was designed to evaluate the one-year survival of patients with head and neck cancer and related demographic factors.

The present study was a cross-sectional study that reviewed the records of the patients with head and neck cancer (193 patients) in 2007-2013. In this study, Kaplan-Meyer method and Cox multiple regression were used to analyze the data. In this study, the information obtained by Excel and Stata 16 software was analyzed.

The results showed 117 (60.6%) patients were male and 76 (39.4%) were female. The mean age of the patients at the time of diagnosis was 62.51± 7.76. Three, six and 12-month survivals were 66.3%, 40.5% and 11.1%, respectively. The results showed that only the age of the patients had a significant relationship with the survival of patients up to one year (HR=65.13, CI= 4.52-41.19).

One-year survival of patients with head and neck cancer in Yazd City is low and the elderly usually have a lower survival than young people.
