Abstract:
Objective To evaluate clinical characteristics and prognostic factors of synchronous multiple primary esophageal carcinomas (SMPEC).Methods Clinical data including sex,age,smoking history,regions,lymph node status,length of tumor,therapeutic methods and survival data of 52 patients with SMPEC were analyzed.The rates of OS depending on the different factors were calculated using the method of Kaplan-Meier analysis.Log-rank test was used for univariate survival analysis and Cox's proportional hazards regression model was used for multivariate survival analysis.Results The 1-,3-,5-year OS rates and the median survival time (MST) were 65.4 ％,17.3 ％,7.7 ％ and 15.0 months for the whole cohort,75.0 ％,33.3 ％,16.7 ％ and 19.5 months for the surgery subgroup,62.5 ％,10.0 ％,5.0 ％ and 14.5 months for the 40 non-operative patients.Multivariate analysis of prognostic factors identified that tumor length and M stage were independent prognostic factors for the whole cohort,while tumor length,M stage and chemotherapy were independent prognostic factors for the radiotherapy subgroup patients.Conclusion The tumor length and M stage are independent prognostic factors for the SMPEC patients.Combined radiotherapy with chemotherapy seems to bring survival benefit and maybe a better management choice for unresectable and non-operative SMPEC.
