RESUMO
Intrahepatic cholangiocarcinoma is a highly invasive malignant tumor, and at present, surgical resection is the only effective way for cure. Lymph node metastasis makes it difficult to accurately judge the extent of radical resection, and no international consensus has been reached on the need for routine lymph node dissection and the extent of lymph node dissection. This article summarizes and analyzes the disputes and problems in preventive lymph node dissection for patients without lymph node metastasis before surgery, hoping to provide a reference for radical resection of intrahepatic cholangiocarcinoma.
RESUMO
Intrahepatic cholangiocarcinoma (ICC) is the second most frequently occurring primary liver cancer. It has been reported that the causes of late diagnosis of ICC are a high degree of malignancy, early metastasis, and diffusion. Most patients visit the hospital because of jaundice or discomfort due to the surrounding compression. ICC commonly recurs after resection, and chemotherapy is not sensitive. Therefore, patients have a poor prognosis and a low survival rate. Currently, a multidisciplinary approach based on surgery is recommended for ICC patients who can undergo surgical excision, and local treatment combined with chemotherapy is the main com-prehensive treatment for patients with advanced ICC who cannot undergo surgical resection. In recent years, it has been found that immunotherapy can involve the autoimmune system to remove tumor cells, and molecular-targeted therapy can kill tumor cells by in-hibiting cell membrane surface molecules that promote tumorigenesis and development. At present, these two treatment modalities have become the research focus of ICC therapy, and progress has been made. The research status is reviewed in this paper.
