ABSTRACT
Objective:To analyze the incidence,treatment and resource consumption of primary oral squamous cell carcinoma (OSCC) in Beijing inhabitants.Methods:Consecutive cases of primary OSCC of Beijing inhabitants admitted to the Stomatology Hospital of Peking University between 2009-2013 were selected from the medical record department.A retrospective analysis was performed on the clinical data which including age,sex,sites,TNM stage,habits of smoking and drinking,treatment,fees,etc.Results:415 cases were included in this analysis.The male-to-female ratio was 1.2∶ 1.Tongue was the most common affected site(41.0％).The difference of the distribution of the affected sites between male and female patients was statistically significant(P ＜0.01).96.6％ patients were diagnosed above the age of 40 years with the median age of 64(56,73).The difference of the distribution of age between male and female patients was statistically significant(P ＜ 0.01).The patients with stage Ⅲ-Ⅳ accounted for 54.9％.With the development of T stage of the primary tumor,the average hospital fee,surgery fee and hospitolization time increased correspondingly.Conclusion:Late stage OSCC accounts for over half of all OSCC patients.The consumption of medical resources increases significantly with the development of tumor,thus more preventive measures are required.
