通过对536例食管癌术后患者1~4年的随访，发现癌旁食管切除长度从1至10cm以上时，复发率为20．0％至0％，转移率为65．0％至11．7％，死亡率为40．0％至8．8％，末发现转移及复发的“无痛”生存率为25．0％至88．2％。表明癌旁食管切除长度与术后复发、转移、死亡率呈负相关，而与生存率呈正相关。 Through the follow-up of 536 patients with esophageal cancer from 1 to 4 years, the recurrence rate was from 20.0% to 0%, and the metastatic rate was 65.0% to 11.1%. At 7%, the mortality rate was 40.0% to 8.8%, and the “painless” survival rate for metastases and recurrences was found to be 25.0% to 88.2%. It showed that the length of esophageal resection was negatively correlated with postoperative recurrence, metastasis, and mortality, but positively correlated with survival rate.
