Regional or Extend LymphAdenectomy During Resection of Intrahepatic Cholangiocarcinoma

NCT ID: NCT04078230Sponsor: Second Affiliated Hospital, School of Medicine, Zhejiang UniversityLast updated: 2022-11-09

Summary

Intrahepatic cholangiocarcinoma (ICC) is one of the common malignant tumors. Lymph node metastasis is an important factor affecting the poor prognosis of intrahepatic cholangiocarcinoma. The eighth edition of the AJCC guidelines recommends at least 6 lymph nodes to be used for staging. The American Hepatobiliary and Pancreatic Association also recommends the removal of hilar lymph nodes as part of the radical surgery for intrahepatic cholangiocarcinoma. However, some scholars have found that patients with regional lymph nodes have similar survival rates. This contradictory result has prompted more scholars to conduct clinical research to explore the necessity and standardization of lymph node dissection in intrahepatic cholangiocarcinoma.

Detailed description

Expanding lymph node dissection can theoretically obtain more lymph node dissection. Obtaining enough lymph nodes can improve the accuracy of AJCC staging and accurately determine prognosis. However, it is unclear whether it will improve the prognosis of patients with lymph node dissection. According to literature reports and related studies, expanded lymph node dissection for right liver tumors included stations 12, 8, and 13, and left lymphoma expanded lymph node dissection includedstations 12, 1, 3, 7, and 8. In summary, standardize the extent of lymph node dissection in intrahepatic cholangiocarcinoma, and obtain enough lymph node dissection under the premise of controlling the complication rate, which is helpful for accurate TNM staging, accurate judgment of prognosis and improvement of survival time. Improve prognosis.
