Abstract:
OBJECTIVETo investigate the relationship between lymph node metastasis and prognosis in patients of intrahepatic cholangiocarcinoma (ICC).
METHODSA retrospective clinical analysis was made in 132 cases of ICC, who admitted to our hospital from December 1996 to June 2003. Kaplan-meier method was used to calculate their survival rates, chi(2) test to compare the difference of sample rates. Logistic regression analysis was performed to determine the factors influencing lymph node metastasis and log-rank univariate analysis was used to assess the role of lymph node metastasis in the long-survival.
RESULTSLymph node metastasis in hepatoduodenal ligament could be detected in all 29 preoperative and 48 postoperative lymph metastatic cases, without "jumping-metastasis". Lymph metastasis was one of the major causes of postoperative mortality, and resulted in 36 of 58 followed-up death postoperatively. According to logistic analysis, pathological types of the carcinoma (chi(2) = 4.071, P = 0.044) and periductal-infiltrating tumors (chi(2) = 3.872, P = 0.037) were significant predictors of lymph node metastasis. In all 98 radical resections, 46 cases performed skeletonization of the hepatoduodenal ligament while other 52 cases not. The median survival of the two groups was 20 months and 13 months respectively (chi(2) = 9.82, P < 0.01).
CONCLUSIONSLymph nodes in the hepatoduodenal ligament may be sentinel nodes for ICC lymph node metastasis. Aggressive treatment of lymph node metastasis in the hepatoduodenal ligament is an important strategy to improve the long-survival of postoperative ICC patients.
