探讨食管癌手术后复发的因素及肿瘤周围应切除的范围。方法：对１０３例Ｔ３胸段食管癌行常 规根治性手术切除后，将肿瘤所在部位的瘤床组织再行进一步切除，切除的瘤床组织做标记后送病理检查。结 果：切除的瘤床组织中病理检查发现有癌残留者共５例，占全部病例的４．８５％（５／１０３）。结论：Ｔ３胸段食管癌行 常规根治性手术切除后，仍有少数病人存在瘤床癌残留，而成为术后复发的原因。因此，除适当扩大手术范围外， 术后应行放疗或化疗，以改善疗效。
To investigate the recurrence of esophageal cancer after surgery and the extent of resection should be around the tumor. METHODS: After 103 cases of T3 thoracic esophageal cancer were treated with conventional radical resection, the tumor bed tissue at the site of the tumor was further resected and the resected tumor bed tissue was used as a marker for pathological examination. RESULTS: There were 5 cases with cancer residuals in pathological examination of the resected tumor bed, accounting for 4.85% (5/103) of all cases. Conclusion: After routine radical radical resection of T3 thoracic esophageal cancer, there are still a small number of patients with tumor bed residuals, which may be the cause of postoperative recurrence. Therefore, in addition to the appropriate expansion of the scope of surgery, postoperative radiotherapy or chemotherapy should be performed to improve the efficacy.
