食管癌手术瘤周切除范围的临床研究

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。

Clinical study of resection scope around the tumor for esophageal carcinoma

To explore recurrence factors after resection and appropriate resection scope for the patients with thoracic esophageal carcinoma. Methods: After standard esophagectomy was opertated on 103 patients, more excision of adju cent structures around the tumor was performed, and resected specimens of adjucent structures were pathologically examined. Results: The rate of residual carcinoma found at adjucent structures was 4.85% (5/103). Conclusion: Some patients remained residual careinoma after standard esophagectomy for T3 esophageal carcinoma. It is suggested that more extensive resection should be performed on the patients with T3 esophageal carcinoma and postoperative adjuvant radiotherapy or/and chemotherapy should be adopted to reduce recurrence and metastasis.
