Survival condition and predictive model in a large data of esophageal squamous cell carcinoma / 中华胸心血管外科杂志

ABSTRACT

Objective The survival and prognosis factors of thoracic esophageal squamous cell carcinoma patients after radical resection was investigated.Methods 1923 patients of thoracic esophageal squamous cell carcinoma after radical resection were included in our study from January 1th 2000 to January 1th 2010 in Zhejiang Cancer Hospital,1 670 male and 253 female.the age in the majority with 40 to 59 years old(1 076/1 923,56.0％).Eighteen prognosis factors were collected.A multivariate analysis of these selected variables was performed using Cox proportional model and prognosis index.We used life table for accumulated survival rate.Results The accumulated survival rate for all patients were 82％,48％ and 35％ in 1 year,3 years and 5 years,respectively.Median survival time was 35.42 months.The significant prognosis factors included body mass index,length of tumor,depth of invasion,differentiation degree,lymph node metastatic degree and region,complication of surgery.Conclusion The prognosis of thoracic esophageal squamous cell carcinoma was affected by multi-factors and prognosis index can predict survival condition.
