Abstract: OBJECTIVE: To investigate survival of patients with esophageal cancers,analyze prognostic factors and establish a prognostic model. METHODS: A retrospective analysis was performed on 186 patients with esophageal cancers who were admitted to the General Hospital of Veterans of Hebei Province in Xingtai,China from February 2013 to August 2017. Demographic characteristics,and clinical and pathological data of patients were collected via telephone interviews,outpatient follow-ups or inpatient reexaminations. The first date of diagnosis of a patient was designated as the starting point of the observation time,the last follow-up time or the death event of the patient was the end point,and the last follow-up time was December 30,2020. RESULTS: Among the 186 patients,162 cases (87.10%) were males,181 cases (97.31%) were Hans,144 cases (77.42%) were squamous cell carcinomas,and 135 cases (72.58%) were in clinical stages III-IV. Up to the last follow-up time,45 patients survived,and the average survival time of all patients was (33.48 ±1.72) months. The 1-,3- and 5-year survival rates were 68.89% (130/186 cases),41.94% (78/186) and 24.19% (45/186),respectively. Cox multivariate analyses showed that smoking history,T3-4 stage,N1 stage and M1 stage were factors for good prognosis,and surgery was a protective factor (P<0.05). Expression of the survival risk function for the patients was h(t)=h0(t)exp (1.038×smoking history+0.419×T stage+1.062×N stage+0.772×M stage-1.100×surgical history). The larger the function index,the greater the risk. The concordance index was 0.772 with a standard error of 0.013,with high internal consistency. CONCLUSION: The 5-year survival rate of our patients was relatively low. Their prognosis was mainly affected by smoking history,T stage,N stage,M stage and surgical status. The nomogram constructed with the above indicators can be used to predict prognosis of patients with esophageal cancers.
