RESUMEN
Objective To analyze the clinical features and onset factors of esophageal cancer.Methods The SPSS 13.0 software was adopted to establish the computer records management system of esophageal cancer.The clinical data in 2 261 clinically cured discharged cases of esophageal cancer from January 2011 to December 2013 were statistically analyzed.Results Forty-nine cases (2.17％) were in the 30-＜40 years old group,324 cases (14.33％) were in the 40-＜50 years old group,963 cases (42.59％) were in the 50-＜60 age group,790 cases (34.94％) were in the 60-＜70 age group and 135 cases (5.97％) were in the 70 years old or more group.Among 2 240 cases,2 031 cases (90.36 ％) showed the different differentiation degrees of squamous epithelial carcinoma by histological analysis,the invaded range displayed fibrous membrane(T3) in 759 cases(33.57％) and peripheral tissue(T4) in 682 cases(30.16％);having smoking and drinking history was in 1 281 cases(56.67％) and 1 025 cases (45.33 ％) respectively;596 cases (26.36 ％) had genetic family history,75.08 ％ was father positive or mother positive.Conclusion Esophageal cancer is mainly squamous cell carcinoma,the onset age is mainly concentrated at the age 50-＜70 years old,which is correlated with smoking and drinking years,moreover has obvious genetic susceptibility.
