The resectability of hepatocellular carcinoma is determined by the extent of hepatic involvement, the presence or abscence of venous invasion and the presence or abscenceof extrahepatic metastasis. Extrahepatic spread to regional lymph node represent contraindincation to surgical resection. Regional lymph node involvement were divided into four main groups with subgrouping according to the location and lymphatic pathway. 1. Lymph nodes in lesser omentum : Hepatic, portocaval, left gastric and celiacnodes. 2. lymph nodes around pancrease head : subpyloric, superior mesenteric, preaortic retropancreatic, and precaval retropancreatic lymph nodes. 3. paraaortic nodes : left paraaortic, interaorticocavalm, retrocaval and preaortic below 3rd duodenum. 4. phrenic nodes : lower parasternal, middle phrenic and retrocrural nodes. RESULT : 1. The frequency of regional node involvement, cases collected at New York Hospital-Cornel medical center, is hepatic node in 5, portocaval node in 8, left gastric in 4, celiac in 7, precaval retropancreatic in 5, preaortic retropancreatic in 4 interaorticocaval in 7 retrocaval in 4 and lower parasternal in. 2. The frequency of regional node involvement, cases collected at Yonsei University college of medicine, is hepatic in 20.5%, pportocaval in 24.7% left gastric in 19.2% celiac in 19.2%, precaval retropancreatic in 8.2%, preaortic retropancreatic in 5.5%, left paraaortic in 12.3%, interaorticocaval in 12.3%, retrocaval in 11.0% low parasternal in 0.8%, superior mesenteric in 4.1% subpyloric 1.4% and preaortic below 3rd duodenum in 1.4%. 3. High chance of regional node involvement can be found in nodes in lesser omentum which located in the main lymphatic pathway, followed by paraaortic lymph node involvement via retropancreatic lymph node involvement.
