OBJECTIVETo summarize the experience of surgical resection of 103 hilar cholangiocarcinoma.

METHODSOne hundred and three consecutive cases of hilar cholangiocarcinoma who underwent surgical resection at our hospital over the past ten years were reviewed retrospectively. The clinical data and long-term outcome were analyzed.

RESULTSOut of 103 cases, 43 patients underwent radical resection (41.7%), and 60 patients underwent palliative resection. There were 34 patients developed postoperative complications and 8 patients died in hospital. For the radical resection group, the median survival time was 29.9 months and 1-year, 3-year, 5-year survival rate was 69.6%, 42.0%, 20.9%, respectively, which was significant greater than 34.1%, 10.2%, 0 of the palliative resection group (P < 0.05). Over the past five years, 42 cases underwent pre-operative drainage of bile and the rate of combined liver resection reached 53.8%. The tumor radical resection rate has increased to 45.7%, the median survival time have reached 24.7 months (P < 0.05).

CONCLUSIONSImprovement of pre-operative management, intraoperative pathology for resection margin, and combined liver resection may help in increasing the radical resection rate. Radical resection can improve postoperative survival, and produce a satisfactory outcome for patient with hepatic hilar cholangiocarcinoma.

BACKGROUND/AIMS: Although diagnosis and surgical treatment for distal common bile duct cancer have enormously advanced, survival is not satisfactory and its prognostic factors are still being debated. Thus, we evaluated the outcomes and prognostic factors after major resection for distal extrahepatic cholangiocarcinoma (dCC). METHODS: One hundred and fifty-four patients who underwent major resection such as pancreaticoduodenectomy for dCC were retrospectively analyzed. We investigated clinical features, postoperative complications, survival, and prognostic factors of dCC. CONCLUSIONS: One hundred and three (66.9%) male and 51 (33.1%) female patients were enrolled and their mean age was 59.6 (31-78) years. Among them, 97 patients (63.0%) underwent Whipple's procedure, 45 (29.2%) pylorus-preserving pancreaticoduodenectomy, 7 (4.5%) total pancreatectomy, and 5 (3.3%) hepatopancreaticoduodenectomy, respectively. Mean follow-up duration was 26.6 (0.4-108.5) months. The postoperative morbidity and mortality were 42.2% and 1.3%, respectively. Five-year survival rate was 32.8% and mean survival duration was 47.2 (39.1-55.3) months. Type of biliary drainage (percutaneous transhepatic biliary drainage), lymph node status (positive), and cellular differentiation (moderate or poor) were significant indicators for death in multivariate analysis of resectable dCC. CONCLUSIONS: Moderate or poor cellular differentiation and lymph node metastasis may be independent poor prognostic factors for resectable dCC.

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.

OBJECTIVETo summarize the experience in ameliorating curative resection rate and major postoperative complication rate for treatment of hilar cholangiocarcinoma.

METHODSRespective analysis was made on the clinical data of 54 consecutive cases who underwent resection of hilar cholangiocarcinoma from Jan. 1998 to Dec. 2004.

RESULTSIn this group 54 cases received tumor resection with a resection rate of 63.5%. Combined partial hepatectomy was performed in 14 patients, while combined pancreaticoduodenectomy (Whipple) in 3 patients, and combined resection of portal vein in 2 patients and combined resection of hepatic artery in 2 patients. Thirty patients had curative resection. The curative resection rate was greatly increased from 27.0% (before 2001) to 41.7% (after 2001) in this group with well controlled perioperative mortality and postoperative complications rate (e.g. hepatic failure and major infection). The gross 1-, 2-, and 3-year survival rates for the whole group were 67.4%, 28.1% and 13.5% respectively. The 1-, 2-, and 3-year survival rates for curative resection were 87%, 36% and 24% respectively. The 1-, 2-year survival rates for palliative resection were 42% and 18%.

CONCLUSIONSEnhanced surgical technique resulted in better clinical outcomes.

BACKGROUNDThe management of intrahepatic cholangiocarcinoma (ICC) remains a challenge due to poor prognosis. The aim of this study was to summarize the surgical management experience in recent 10 years and to identify the influencing factors related to outcome of patients with ICC in a single hepatobiliary center.

METHODSFrom January 1995 to June 2005, 136 patients with ICC undergoing surgery were reviewed retrospectively. Survival rates of patients were calculated using the Kaplan-Meier method and compared by using the log-rank test. The prognostic factors were identified by the Cox regression model.

RESULTSSeventy-nine of 136 patients underwent resection, and 65 of 79 patients were curative (R0). The surgical mortality was 2.2%. The 1-, 3- and 5-year survival rates of patients undergoing R0 resection were 72.1%, 35.6% and 20.1% respectively, which were significantly longer than those who underwent palliative resection and exploration, respectively (P < 0.01). At stage IV of the disease, 10 patients who underwent aggressive curative resection achieved a better median survival than those (n = 12) without resection (14 months vs 3 months, P < 0.001). The independent prognostic factors of the whole group were TNM stage (OR, 2.013, P = 0.008) and curative resection (OR, 2.957, P = 0.003). Higher TNM stage (OR, 1.894, P = 0.004) and lymph node metastasis (OR, 4.248, P = 0.005) linked to poor prognosis after R0 resection. For patients without lymph node metastasis, the median survival of those who underwent regional lymphadenectomy was comparable with those who did not (18 months vs 22 months, P = 0.817).

CONCLUSIONSR0 resection is mandatory for ICC patient to achieve long-term survival. Aggressive resection benefits for selected patients with local advanced disease. Higher TNM stage and lymph node metastasis were poor prognostic factors for ICC patients after R0 resection.

OBJECTIVETo evaluate the clinical value of T-staging system for hilar cholangiocarcinoma which was adopted in memorial Sloan-Kettering cancer center of New York.

METHODSThe image data of these 47 patients were analyzed retrospectively from December 1997 to December 2002 whose data were according with our demand, and they were staged into three-stage according to the criteria of the T-staging system. The difference of respectability, ratio of tumor-free resection margin and actuarial survival rate were analyzed for different T-staging. And the coincident ratio of three different kinds of imaging methods was also analyzed.

RESULTSTwenty patients had T(1) tumors, twenty three had T(2) tumors and four had T(3) tumors. The resectability of the three stage was 60%, 39% and 0% respectively, and the difference was significant (P = 0.013). The likelihood of achieving tumor-free margin decreased progressively with increasing T stage (P = 0.018). The cumulative 1-year survival rates of T(1), T(2) and T(3) patients were 60%, 39% and 0% respectively, and the cumulative 3-year survival rate was 35%, 9% and 0% respectively, the survival of different stage patients differed markedly (P = 0.0103). The coincident ratio of combined using MRCP and color Doppler-ultrasonography was higher than that of combined using MRCP and B-ultrasonography or combined using CT/SCT and color Doppler-ultrasonography (P = 0.007).

CONCLUSIONSThe T-staging system has a better value for preoperative assessment, and can be used to judge resectability and survival of hilar cholangiocarcinoma. It will be helpful to use MRCP and color Doppler-Ultrasonography combined to verdict the coverage of the tumor and the T-staging preoperatively.

BACKGROUNDS/AIMS: Although the survival rate after surgical resection of peripheral cholangiocarcinoma is low, surgical resection is only potentially curative therapy. The aim of this study is to evaluate clinicopathological factors affecting survival after surgical resection of peripheral cholangiocarcinoma. METHODS: Between February 1990 and December 2005, surgical intervention with curative intent was performed on 318 patients and 292 patients underwent resection. We retrospectively analyzed survival data of 318 patients and clinicopathological factors affecting survival by reviewing the medical record. RESULTS: Among the 292 cases of resection, curative resection with tumor-free margin (R0) has been resulted in 221 cases. The 1-, 3-, 5- and 10-year survival rate of R0 resection were 74.9, 46.9, 36.9 and 15.2%, respectively. The survival rate of patient undergoing R0 resection was significantly better than that of R1, R2 or nonresection. Multivariate analysis showed that curative resectability, macroscopic type of tumor and lymph node metastasis were statically significant independent prognostic factors. CONCLUSIONS: The survival after surgical resection of peripheral cholangiocarcinoma depends on curability of surgical resection, macroscopic type of tumor and status of lymph node. Particullary in R0 resection for intraductal growth type without lymph node metastasis, there is great chance for long-term survival. Surgical resection attaining tumor free margin should be attempted if liver function and general condition of patient are acceptable for hepatectomy.

BACKGROUND/AIMS: Combined hepatocellular and cholangiocarcinoma (HCC-CC) is a rare form of primary liver carcinoma which contains characteristics of both hepatocellular carcinoma and cholangiocarcinoma. The aim of this study was to evaluate the prognostic factors of combined HCC-CC after curative resection. METHODS: Between January 1987 and December 2005, pathologically confirmed combined HCC-CC patients who underwent curative resection at Seoul National University Hospital were evaluated. We reviewed the medical records and evaluated the time-to-recurrence (TTR), overall survival (OS) and prognostic factors of combined HCC-CC. RESULTS: A total of 31 patients were evaluated (M:F=27:4; median age, 61 years). According to the American Joint Committee on Cancer system, patients with stage I, II, III(A), III(B) and III(C) at the time of resection were 4, 16, 7, 2 and 2, respectively. Twenty six patients (83.9%) had tumor recurrence during the follow-up period and their median TTR was 5.7 months. Twenty one patients received additional treatment while 5 patients did not. As a result, median OS was 21.6 months and 3 year survival rate was 15.4%. In multivariate analysis, stage III than stage I or II at resection was an independent prognostic factor associated with shortened TTR (p<0.01). Older age (p=0.03), stage III(C) rather than stage I, II, III(A) at time of resection (p=0.02), and Child-Pugh B rather than A (p<0.01) were independent prognostic factors associated with shortened OS. CONCLUSIONS: Even after curative resections, patients with combined HCC-CC show poor prognosis with early recurrence and poor survival. However, surgical treatment should be warranted for relatively young patients in early stage with well preserved liver function.

OBJECTIVETo evaluate the role of vascular resection and reconstruction in the treatment of hilar cholangiocarcinoma.

METHODS117 patients with potentially resectable hilar cholangiocarcinoma underwent exploration. Twenty-one patients had exploration or drainage only due to distant metastases, and the other 96 patients received surgical resection. Thirty-one of those had vascular resection and reconstruction, including portal vein resection alone in 21 patients, combined hepatic artery and portal vein resection in 2 and hepatic artery resection alone in 8. Therefore, the patients were divided into four groups: non-surgical resection (21), portal vain resection (21), hepatic artery resection (10) and non-vascular resection (65) and their clinical data were reviewed retrospectively.

RESULTSThe hepatic artery resection group had significantly higher perioperative morbidity and mortality rate (80.0% and 20.0%) than non-vascular resection group (16.9% and 1.5%), respectively, (P < 0.05), while no significant difference was found between the portal vein resection alone group and the non-vascular resection group (P > 0.05). Of all resected vessel specimens, vascular wall invasion beyond the adventitia was pathologically confirmed in 82.6% of the portal veins and 50.0% of the hepatic arteries. The 1-, 3- and 5-year survival rates were 59.0%, 34.0%, and 16.0% in the non-vascular resection group, versus 44.0%, 23.0% and 11.0% in the portal vein resection alone group (P < 0.05) and 18.0%, 0 and 0 in the hepatic artery resection group (P < 0.01), respectively, with a significant difference among the three groups. The 1-, 3- and 5-year survival rates in the non-surgical resection group were 13.0%, 0 and 0, respectively, which were similar to those in the hepatic artery resection group. Though a significant difference in survival rates existed between the portal vein resection alone group and non-resected group (P < 0.001), no significant difference was found between the hepatic artery resection group and non-resected group (P > 0.05).

CONCLUSIONBoth portal vein and hepatic artery resection can improve resection rate for hilar cholangiocarcinoma, and portal vein resection may improve the prognosis in selected patients. However, hepatic artery resection can not improve survival and may even lead to an increase of perioperative morbidity and mortality.
