An analysis of intrahepatic lymphatic invasion in the patient with intrahepatic cholangiocarcinoma

肝内胆管细胞癌是第二常见的肝脏恶性肿瘤。淋巴结转移是影响ICC根治性切除患者生存率的重要因素之一。因此，对于术前诊断有淋巴结转移的ICC患者，手术治疗中淋巴结清扫的价值或手术切除的指征仍存在争议。本研究旨在探讨肝内淋巴管浸润与淋巴结转移的相关性。我们还调查了ICC患者根治性切除后的结局，以分析淋巴结清扫对生存和复发的影响。

Intrahepatic cholangiocarcinoma (ICC) arising from the intrahepatic bile duct is the second most frequent hepatic malignancy. Lymph node metastasis is known to be one of strong prognostic factors for survival in the patients undergoing curative resection for ICC. Therefore, the value of lymph node dissection during surgical treatment for ICC or indication of the resection for the patients who are preoperatively diagnosed to have metastatic lymph nodes is still in debate.In this study, we evaluated correlation between intrahepatic lymph vessel invasion and lymph node metastasis. We also investigated the outcomes of ICC patients following curative resection to analyze the influences of lymph node dissection on survival and recurrence.
