Five- and ten-year survival of squamous cell carcinoma of the head and neck in northern Thailand: a multivariate analysis
Published online by Cambridge University Press: 13 August 2020
Abstract
To report 5- and 10-year overall survival (OS) outcomes of squamous cell carcinoma of the head and neck and identify prognostic factors.
Data on 2,095 patients at Maharaj Nakorn Chiang Mai Hospital, Thailand between 2007 and 2014 were analysed using the Kaplan–Meyer method to estimate 5- and 10-year OS rates. Cox proportional hazard regression models were applied to assess the independent prognostic factors of survival.
8·7% had hypopharyngeal cancer, 19·7% laryngeal, 53·3% oral cavity and 18·3% oropharyngeal. Two-thirds of the patients had locally advanced stage (III–IVB). Five- and ten-year OS rates were 30·1 and 22·8%, respectively.
Cancer site, stage and age at diagnosis were associated with mortality, highlighting the importance of prevention and early detection.
