Abstract:
Objective To compare of clinical effect between radiotherapy and chemoradiotherapy and investigate the prognostic factors in elderly patients with esophageal squamous cell cancer.Methods 229 elderly patients with esophageal squamous cell cancer who received radiotherapy and chemoradiotherapy from January 2009 to December 2013 were retrospective analyzed.The Local control rate and survival rate were calculated by Kaplan-Meier method,and the short effect and long term effect between radiotherapy and chemoradiotherapy were compared.Cox regression model was used for invariant analysis and multivariate analysis.Results The follow up time was 15.3months.The short effect of radiotherapy group was not better than that of chemoradiotherapy group,with CR 35.6％ vs 45.8％,RR 61.0％ vs 53.0％,SD 2.7％ vs 0 and PD 0.7％ vs 1.2％ (P=0.211).The 1-,2-,3-year local control rates of radiotherapy group were significantly poorer than that of chemoradiotherapy group,with 82.8 ％,60.5 ％ and 52.7％ vs 89.5％,85.4％ vs 80.9％,respectively (P=0.009).However,there were no significance difference between the 1-,2-,3-year survival rates of radiotherapy group and chemoradiotherapy group,with 66.4％,29.5％,17.1％ vs.65.9％,40.3 ％,30.8 ％,respectively (P =0.071).In invariant analysis,T stage,N stage,clinical stage and radiotherapy dose (＜ 60 Gy,60 ～66 Gy,＞66 Gy) were related with the prognosis of esophageal carcinoma.The COX regression model showed that T stage,N stage and radiotherapy dose were independent prognostic factors that effected survival rate.Conclusion In elderly patients with esophageal squamous cell cancer,chemoradiotherapy can improve the local control rates,but not benefit the survival rate.T stage,N stage and radiotherapy dose were independent prognostic factors that effected survival rate,which could provided evidence for prognosis judgement and clinical practice.
