目的 :研究食管癌脉管内瘤栓形成与其相关危险因素之间的关系,以选择合理的治疗方法。方法 :回顾分析1 867例接受手术治疗食管癌患者临床病理资料。研究脉管内瘤栓与性别、年龄、血型、肿瘤浸润深度(T)、淋巴结阳性率(LNM)及阳性淋巴结转移率(PLNR)之间的关系。结果:脉管内瘤栓与T分期、淋巴结阳性率及阳性淋巴结转移率密切相关(P<0.01),对于T分期的进一步分析提示:统计学差异主要表现在T_(1a)与T_(1b)~T_4以及T_1~T_3与T_4之间。结论:食管癌脉管内瘤栓的形成与肿瘤浸润深度T及淋巴结转移密切相关。对于合并有脉管内瘤栓的早期食管癌患者(T1a/T1b)应选择外科手术治疗。
Objective: To study the relationship between the formation of vascular thrombus in esophageal cancer and its related risk factors in order to select a reasonable treatment. Methods: A retrospective analysis of 1 867 patients undergoing surgical treatment of esophageal cancer patients with clinicopathological data. To study the relationship between vascularization thrombus and gender, age, blood type, tumor invasion depth (T), lymph node positive rate (LNM) and positive lymph node metastasis rate (PLNR). Results: Vascular plugs were closely related to T stage, lymph node positive rate and positive lymph node metastasis rate (P <0.01). The further analysis of T stage suggested that the statistical difference mainly manifested in T 1a and T 1b ~ T_4 and T_1 ~ T_3 and T_4. Conclusion: The formation of endovascular tumor suppositories is closely related to the depth of tumor invasion and lymph node metastasis. For patients with early esophageal cancer (T1a / T1b) with vascular thrombus, surgery should be selected.
