食管粘膜下癌淋巴结转移12例

12 Ccses of Submucosal Carcinoma of Esophagus with Lymphatic Metastasis

探讨食管粘膜下癌发生淋巴结转移的有关因素及特点，制定治疗早期食管癌的最佳方案。方法：手术切除食管粘膜下癌52例，常规清扫区域淋巴结，分组病理检查，术后进行长期随诊。结果：本组食管粘膜下癌淋巴结转移率为23．1％（12/52），发生淋巴结转移主要与肿瘤的分化程度有关，分化越差，转移率越高，其次与肿瘤的大小、病理形态类型等因素有关。跳跃式转移发生率高，转移淋巴结大部分≤1cm，可能是食管粘膜下癌发生淋巴结转移的特点。结论：对早期食管癌应行食管次全切除术，并常规清扫区域淋巴结。

To study characteristics and factors about the submucosal carcinoma of esophagus with lymphatic metastasis and formulate the best treatment for the patients with the early esophageal carcinoma. Methods: 52 cases with submucosal carcinoma of esophagus were treated by surgical resection and routine clearance of regional lymph nodes. The specimens were examinde by pathology respectively. All of the patients were follow-up for a long time. Result: The incidence of lymphatic metastasis was 23. l % (12/52). The lymphatic metastasis was principally related to the differential degree of tumor. The lower the differential degree was, the higher the incidence of lymphatic metastasis would be. Secondly, it was concerned with the size and pathomorphological classification of tumor. The characteristics of lymphatic metastasis would be the jumping transfer and the size of the invaded lymph nodes ≤1cm. Conclusion: The subtotal esophagectomy and the clearance of regional lymph nodes was advised for early carcinoma of esophagus.
