World J Gastrointest Oncol 2021; 13:2190-2202. [PMID: 35070051 PMCID: PMC8713310 DOI: 10.4251/wjgo.v13.i12.2190] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Revised: 07/05/2021] [Accepted: 09/17/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The long-term effect of anatomic resection (AR) is better than that of non-anatomic resection (NAR). At present, there is no study on microvascular invasion (MVI) and liver resection types.
AIM To explore whether AR improves long-term survival in patients with hepatocellular carcinoma (HCC) by removing the peritumoral MVI.
METHODS A total of 217 patients diagnosed with HCC were enrolled in the study. The surgical margin was routinely measured. According to the stratification of different tumor diameters, patients were divided into the following groups: ≤ 2 cm group, 2-5 cm group, and > 5 cm group.
RESULTS In the 2-5 cm diameter group, the overall survival (OS) of MVI positive patients was significantly better than that of MVI negative patients (P = 0.031). For the MVI positive patients, there was a statistically significant difference between AR and NAR (P = 0.027). AR leads to a wider surgical margin than NAR (2.0 ± 2.3 cm vs 0.7 ± 0.5 cm, P < 0.001). In the groups with tumor diameters < 2 cm, both AR and NAR can obtain a wide surgical margin, and the surgical margins of AR are wider than that of NAR (3.5 ± 5.8 cm vs 1.6 ± 0.5 cm, P = 0.048). In the groups with tumor diameters > 5 cm, both AR and NAR fail to obtain wide surgical margin (0.6 ± 1.0 cm vs 0.7 ± 0.4 cm, P = 0.491).
CONCLUSION For patients with a tumor diameter of 2-5 cm, AR can achieve the removal of peritumoral MVI by obtaining a wide incision margin, reduce postoperative recurrence, and improve prognosis.

Effect of surgical margin width after R0 resection for intrahepatic cholangiocarcinoma: A nationwide survey of the Liver Cancer Study Group of Japan. Surgery 2020; 167:793-802. [PMID: 32044110 DOI: 10.1016/j.surg.2019.12.009] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 12/13/2019] [Accepted: 12/18/2019] [Indexed: 01/22/2023]
Abstract
BACKGROUND Data are inconsistent regarding the effects of a wide surgical margin for intrahepatic cholangiocarcinoma on recurrence-free survival and overall survival. This study was performed to investigate the effect of surgical margin width in patients undergoing R0 resection for intrahepatic cholangiocarcinoma, using a nationwide database in Japan. METHODS In total, 635 patients with intrahepatic cholangiocarcinoma who were treated by an R0 resection from 2000 to 2007 were identified from the database of a Japanese nationwide survey. Patients were divided into quartiles of the surgical margin width as follows: marginal (<1 mm), narrow (1-4 mm), intermediate (5-9 mm), and wide groups (≥10 mm). Multivariable Cox regression models for recurrence-free survival and overall survival were constructed with adjustment for preoperative and postoperative clinicopathologic factors. RESULTS Compared with the marginal group, the risk-adjusted hazard ratios (95% confidence intervals) in the narrow, intermediate, and wide groups for recurrence-free survival were 0.92 (0.62-1.37), 0.91 (0.61-1.37), and 0.81 (0.56-1.17), and those for overall survival were 0.79 (0.51-1.24), 0.93 (0.59-1.47), and 0.70 (0.46-1.08), respectively. In 398 patients without lymph node metastasis, the hazard ratios for overall survival were 0.62 (0.34-1.11), 0.63 (0.34-1.17), and 0.51 (0.29-0.90), and those of mass-forming type intrahepatic cholangiocarcinoma were 0.48 (0.21-1.08), 0.43 (0.19-0.96), and 0.40 (0.19-0.82), respectively. CONCLUSION Surgical margin width appears to have a limited effect on the prognosis of intrahepatic cholangiocarcinoma except in patients without lymph node metastasis, where a wide surgical margin is associated with favorable outcomes. This survival benefit of a wide surgical margin is especially apparent for the mass-forming type intrahepatic cholangiocarcinoma.

Abstract
Biliary tract cancers (BTC) are rare, heterogeneous malignancies that include cholangiocarcinoma and gallbladder cancer (GBC). Cholangiocarcinoma subtypes differ by anatomic location and molecular profile. Currently, resection with lymphadenectomy is the only curative treatment of locally advanced cholangiocarcinoma. Given the high risk of recurrence, multi-modality therapy spanning surgery, chemotherapy, and radiation therapy should be considered. Current data is discordant and there is limited prospective data to support an optimal treatment regimen, though recent studies have demonstrated the utility of adjuvant chemotherapy and chemoradiation in specific settings and patient populations. There is a potential role for neoadjuvant chemotherapy in patients with resectable disease or chemoradiation in select patients with unresectable, locally advanced disease. Randomized clinical trials are necessary to establish the effectiveness of therapies specific to disease sites, especially with the emerging role of immunotherapy and targeted therapy to actionable mutations.

Abstract
Aims and Background Intrahepatic cholangiocarcinoma (IHCC) is the second most common primary liver cancer, representing 10% of all primary liver malignancies. Despite the increase in its incidence, this tumor remains extremely rare in Western countries and few reports detailing experience with surgical resection have been published. The aim of this study was to analyze the experience with resection of IHCC in our center. Methods From 1987 to 2003 we observed 35 patients with IHCC; 15 of them (42.8%) were submitted to hepatic resection. IHCCs accounted for 13% of all liver resections for primary liver tumors carried out at our center during this period. According to the classification of the Liver Cancer Study Group of Japan, the tumors were classified as “mass-forming” in 14 cases and as “periductal” in one case. Major resections were performed in ten cases and minor resections in five cases. In the patient with a periductal tumor a major resection was performed along with excision of the main biliary confluence. In 14 cases (93.3%) tumor-free resection margins were obtained. Results The intraoperative mortality was nil and the postoperative mortality 6.6%. The postoperative morbidity rate was 21.4%. The mean overall survival was 38.4 months, with 86% and 49% one- and three-year survival rates, respectively. Patients with mass-forming tumors and curative resections (R0) (mean survival 40.8 months; one- and three-year survival rates 92.3% and 52.7%), and those with TNM stage I-II tumors (mean survival 43.7 months; one- and three-year survival rates 100% and 66.7%) had a longer survival. The patient with the periductal tumor and R1 resection died after seven months. Conclusions These results support a surgical approach based on accurate selection of patients with IHCC and aimed at radical resection whenever possible. The good survival rates observed in R0 resections emphasize the role of radical surgery as the only chance of cure for patients with this tumor.

Abstract
Intrahepatic cholangiocarcinoma (iCCA) is one of the fatal gastrointestinal cancers with increasing incidence and mortality. Although surgery offers the only potential for cure in iCCA patients, the prognosis is not optimal with low overall survival rate and high disease recurrence. Hence, adjuvant therapy is generally recommended in the management of high-risk patients. Identifying factors associated with disease recurrence and survival of the iCCA patients after resection will improve understanding of disease prognosis and help in selecting patients who will benefit from surgical resection or stratifying them for clinical trials. Despite development of new methods for early detection of tumor recurrence, effective prognostic models and nomograms, and recent advances in management, significant challenges remain in improving the prognosis of iCCA patients.

Abstract
BACKGROUND Surgical resection is shown to present the best chance of cure in the treatment of intrahepatic cholangiocarcinoma (ICC). However, the appropriate length of the negative margin remains unclear. The aim of the present meta-analysis was to investigate whether a clear margin of 10 mm or more (≥10 mm) conferred any survival benefit over a margin of less than 10 mm (<10 mm) in patients with resected ICC. METHODS The meta-analysis was conducted in adherence with the PRISMA guidelines. PubMed, Web of Science, EMBASE, and the Cochrane Library were systematically searched to identify eligible studies published in English from the initiation of the databases to February 2016. Overall survival rates were pooled by using the hazard ratio and the corresponding 95% confidence interval (CI). Random-effect models were utilized because of between-study heterogeneity. RESULTS Six studies (eight cohorts) reporting on 712 patients were analyzed: 269 (37.80%) were in the 10 mm or more negative margin group, and 443 (62.20%) were in the less than 10 mm negative margin group. The pooled hazard ratio for the less than 10 mm group was found to be 1.59 (95% CI: 1.09-2.32) when this group was compared with the 10 mm or more group (reference), with moderate between-study heterogeneity (I = 45.30%, P = 0.07). Commensurate results were identified by sensitivity analysis. CONCLUSION The result of this meta-analysis suggests a long-term survival (overall survival) advantage for negative margins of 10 mm or more in comparison with negative margins less than 10 mm for patients undergoing surgical resection of ICC.

Abstract
INTRODUCTION Prognosis of intrahepatic cholangiocarcinoma (ICC) remained poor despite the multitude advancement of medical care. Resection margin status is one of the few modifiable factors that a surgeon could possibly manipulate to alter the disease outcome. However, the significance of margin status and margin width is still controversial. This study serves to further elucidate the role of them. METHOD This is a retrospective cohort from the Queen Mary Hospital, The University of Hong Kong. Consecutive patients diagnosed to have ICC and with surgical resection performed in curative intent were retrieved, while patients with cholangiohepatocellular carcinoma, Klaskin tumor, tumor of extrahepatic bile duct, and uncertain tumor pathology were excluded. RESULTS From 1991 to 2013, there were 107 patients underwent hepatectomy for ICC. Gender predilection was not observed with 58 males and 49 females, median age of the patients was 61. The median tumor size was 6 cm and most of them (43%) were moderately differentiated adenocarcinoma. Clear resection margin were achieved in 95 patients (88.8%) and the median margin width was 0.5 cm. The hospital length of stay and operative mortality were 11 days and 3%, respectively. The disease-free survival and overall survival were 17.5 and 25.1 months, respectively. Multivariate analysis showed that margin width was an independent factor associated with disease-free survival (P = 0.015, 95% confidence interval [CI] 0.4-0.9). Subgroup analysis in patients with solitary tumor showed that margin width is an independent factor affecting overall survival (P = 0.048; odds ratio: 0.577; 95% CI: 0.334-0.996). Discriminant analysis showed that the overall survival increased from 36 to 185 months when margin width was >0.9 cm (P = 0.025) in patients with solitary tumor. CONCLUSION Aggressive resection to achieve resection margin of at least 1 cm maximizes chance of cure in patients with early ICC.

Abstract
Purpose To assess the value of diffusion-weighted (DW) imaging as a prognostic marker in preoperative evaluation of patients with mass-forming intrahepatic cholangiocarcinoma (ICC). Materials and Methods This retrospective study was approved by the institutional review board, and the informed consent requirement was waived. A total of 91 patients who underwent hepatic resection and DW imaging for mass-forming ICC were included. Two radiologists evaluated the degree of diffusion restriction of the tumors by using qualitative (visual) interpretation combined with quantitative analysis by volumetric evaluation of the whole tumor on DW images. Patients were classified into two groups: those in whom less than one-third of the tumor showed diffusion restriction (group 1) and those in whom more than one-third of the tumor showed diffusion restriction (group 2). Imaging findings in tumors were compared with pathology findings. Disease-free and overall survival rates were compared between the two groups by using the Kaplan-Meier method with the log-rank test. Results There were 43 patients in group 1 and 48 patients in group 2. The 1- and 3-year disease-free survival rates were 30% and 16%, respectively, in group 1 and 75% and 64%, respectively, in group 2 (P < .001). The 1- and 3-year overall survival rates were 77% and 26%, respectively, in group 1 and 92% and 67%, respectively, in group 2 (P = .001). Multivariate analysis revealed that diffusion restriction (P = .024), differentiation (P = .030), and intrahepatic metastasis (P = .001) were independent prognostic factors for overall survival. Conclusion The degree of diffusion restriction on DW images may be a prognostic marker in preoperative evaluation of patients with mass-forming ICC.

Abstract
BACKGROUND/AIMS The need for routine use of preoperative biliary drainage (PBD) before major liver resection in jaundiced patients has recently been questioned. Our aim was to present our experience of patients with proximal bile duct cancer who undergo major liver resection without PBD and compare these results with patients without biliary obstruction who underwent major liver resection. METHODS Eighty six consecutive jaundiced patients underwent major liver resection without PBD. The postoperative outcome was compared to the control group, which was the same size and matched. DESIGN A case-comparison study. RESULTS Fifty nine jaundiced patients (69%) and 22 non-jaundiced patients (25%) received blood transfusion (p = 0.04). Fifty-three patients (62%) in the jaundiced group and 17 (19%) in the non-jaundiced patients experienced postoperative complications (p = 0.003). A statistically significant difference could not be detected for mortality (6 vs. 2%) and transient liver failure (10 vs. 3%). Those patients who underwent extended right hemihepatectomy (with future liver remnant <50%) express high morbidity (55 vs. 24%; p = 0.04) and mortality (23 vs. 8%; p = 0.001) compared to the non-jaundiced patients. CONCLUSIONS Major liver resection without PBD leaving a liver remnant of more than 50% is safe in jaundiced patients. However, transfusion requirement and morbidity are higher in jaundiced patients than in non-jaundiced patients.

Abstract
OBJECTIVES The aim of this analysis was to examine prognostic features and outcomes in patients undergoing resection for intrahepatic cholangiocarcinoma (ICC). METHODS A retrospective chart review was performed in all patients who underwent R0 or R1 resection for primary ICC between 1995 and 2011. Clinical data were abstracted and statistical analyses were conducted in the standard fashion. RESULTS A total of 82 patients underwent curative hepatectomy for primary ICC; 51 patients in this cohort developed recurrence. The median follow-up of survivors was 27 months (range: 1-116 months). Recurrences were intrahepatic (65%), associated with multiple tumours (54%) and occurred during the first 2 years after hepatectomy (86%). The main factor associated with recurrence after resection was the presence of satellite lesions. Overall 5-year disease-free survival after primary resection was 16%. Factors associated with poor survival were transfusion and perineural invasion. Treatment of recurrence was undertaken in 89% of patients and repeat surgical resection was performed in 15 patients. The 3-year survival rate after recurrence was 25%. Prolonged survival after recurrence was associated with a solitary tumour recurrence. CONCLUSIONS Despite curative resection of ICC, recurrence can be expected to occur in 79% of patients at 5 years. Predictors of survival and recurrence after resection vary in the literature. In patients with recurrence, selection of the optimal treatment remains challenging.

Abstract
Staging systems are an attempt to incorporate the biology and therapy for cancer in a way that enables categorization and prediction of oncologic outcomes. Because of unusual disease biology and complexities related to treatment intervention, efforts to develop reliable staging systems for hepatic malignancies have been challenging. This article discusses the ways in which improved understanding of these diseases has informed the evolution of prognostication systems as applied to hepatocellular carcinoma, cholangiocarcinoma, and hepatic colorectal adenocarcinoma.

Abstract
OBJECTIVES Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy after hepatocellular carcinoma. ICC can be divided into 2 types according to their location: peripheral and hilar types. Intense F-FDG uptake on PET was reported in peripheral ICC. However, the usefulness of PET/CT in detecting tumors and predicting prognosis in peripheral ICC has not been fully evaluated. In this study, we evaluated the clinical role of F-FDG PET/CT to predict the recurrence after the curative resection in patients with surgically indicated peripheral ICC. METHODS Eighteen patients with ICC underwent preoperative CT and F-FDG PET/CT scans. SUVmax of tumor, tumor to normal liver SUV ratio (TNR), lymph node status evaluated by F-FDG PET/CT, tumor and lymph node size measured by CT, vascular invasion confirmed by pathology, and satellite nodules found on CT were compared between 1-year recurrence group and recurrence-free group by chi-square test. RESULTS Of total 23 measurable lymph nodes, 4 nodes were positive and other 19 nodes were negative or equivocal on CT. Among those 23 nodes, 9 nodes were positive and other 14 nodes were negative on F-FDG PET/CT. The sensitivity and specificity of CT were 20.0% and 86.4%, and those of F-FDG PET/CT were 80.0% and 92.3%. In the comparison between 1-year recurrent and nonrecurrent groups, lymph node metastasis detected on F-FDG PET/CT had statistically positive correlation with the 1-year recurrence after surgical resection (P = 0.02). Other factors showed no statistically significant difference between the groups. CONCLUSION We found that lymph node metastasis detected on F-FDG PET/CT correlated positively with 1-year recurrence after surgical resection in patients with peripheral ICC.

Abstract
PURPOSE This study aimed at assessing the prognostic factors of resection of intrahepatic cholangiocarcinoma (IHCC), which remain unclear. METHODS Among 70 patients with IHCC, who were admitted to our hospital between 1998 and 2011, 45 (64 %) underwent resection and 25 had unresectable tumors. Univariate and multivariate analyses were conducted retrospectively to assess the factors influencing survival of the patients who underwent resection. RESULTS The median survival times of the patients who underwent resection versus those who did not were 16 months versus 9 months, respectively (P < 0.001). Multivariate analysis identified residual tumor status (relative risk 4.12, P = 0.04) and pathological differentiation (relative risk 5.55, P = 0.04) as independent factors predicting survival. Patients who underwent R1 resection had a significantly higher rate of local recurrence than those who underwent R0 resection (P = 0.008). With R0 resection, there were no significant differences in patterns and rates of recurrence between patients with narrow (≤ 5 mm) versus wide (>5 mm) surgical margins. CONCLUSIONS R0/1 resection and a well-differentiated tumor were found to be independent prognostic factors for long-term survival after IHCC resection. If R0 resection was achieved, the width of the negative surgical margin did not affect the patterns and rates of recurrence.

Abstract
Abstract
Background
The aims of this study were to evaluate risk factors for recurrence following hepatectomy with curative intent for intrahepatic cholangiocarcinoma (ICC), and predictors of survival after intrahepatic recurrence.
Methods
All patients with ICC who underwent liver resection between January 1997 and August 2011 in a single centre were analysed retrospectively. Clinicopathological factors likely to influence recurrence and postrecurrence survival were assessed by univariable and multivariable analysis.
Results
A total of 87 patients were analysed. R0 resection was achieved in 65 patients (75 per cent). Eighty-three patients survived more than 1 month after resection. Median survival was 33 months, with 1-, 3- and 5-year actuarial survival rates of 79, 47 and 31 per cent respectively. Recurrence occurred in 45 (54 per cent) of the 83 patients, most frequently in the liver (25 patients). Satellite nodules (odds ratio (OR) 8·17, 95 per cent confidence interval 1·38 to 48·53; P = 0·021), hilar lymph node metastases (OR 5·24, 1·07 to 25·75; P = 0·041) and perineural invasion (OR 9·68, 1·07 to 87·54; P = 0·043) were identified as independent risk factors for recurrence. Repeat hepatectomy (P = 0·003) and intra-arterial yttrium-90 radiotherapy (P = 0·048) were associated with longer survival after intrahepatic recurrence.
Conclusion
Satellite nodules, hilar lymph node metastases and perineural invasion are risk factors for recurrence following resection with curative intent for ICC. Repeat hepatectomy and labelled yttrium-90 radiotherapy may improve survival after intrahepatic recurrence.

Abstract
PURPOSE To evaluate the efficacy of radiofrequency (RF) ablation for treatment of unresectable intrahepatic cholangiocarcinoma (ICC) and to explore the impact of prognostic variables on outcomes. MATERIALS AND METHODS From 2000-2010, 17 patients with 26 ICCs underwent RF ablation at a single institution. None of the patients were surgery candidates. Seven patients had 15 primary ICCs, and 10 patients had 11 recurrent ICCs. The median largest diameter was 4.4 cm (range 2.1-6.8 cm). A percutaneous approach was used in 15 patients, and an open approach was used in 2 patients. Early tumor necrosis, recurrence-free survival, and overall survival were analyzed. Univariate analysis was performed to evaluate 12 clinicopathologic and treatment-related variables associated with recurrence-free survival and overall survival. RESULTS Early tumor necrosis was 96.2% (25 of 26 tumors). The median follow-up period after RF ablation was 29 months. The median recurrence-free survival and overall survival were 17 months and 33 months. The 1-year, 3-year, and 5-year survival rates were 84.6%, 43.3%, and 28.9%, with an overall complication rate of 3.6% (1 of 28 sessions). Three variables were found to be closely associated with recurrence-free survival: lymph node metastases (P = .023), tumor differentiation (P = .034), and tumor number (P = .035). The only variable significantly associated with overall survival was tumor differentiation (P = .033). CONCLUSIONS Preliminary results showed that RF ablation may be an effective treatment for ICC because it achieved an acceptable survival rate in a small population. Prognostic factors might allow better patient selection and outcomes.

Abstract
Liver resection may represent the only hope of cure for patients with intrahepatic cholangiocarcinoma (IHC) but long-term results are still far from satisfactory and the impact of prognostic factors is still controversial. Fifty-five patients underwent hepatectomy for IHC between 1997 and 2008 in our unit. Features of the patients and the tumors, operations, postoperative and long-term results were retrospectively assessed. Twenty-one patients had HBV/HCV infection, four had congenital biliary dilatation. Thirty-two patients had increased CA 19-9; 12 had multiple (≥ 4) tumors. Operations included 43 major resections, with 9 resections of biliary confluence, 40 regional lymphadenectomies. Operative mortality and morbidity were 0 and 27.3%, respectively. There were 44 R0-resections (80.0%). Lymphadenectomy yielded lymph node metastases in 14 cases (14/40; 35.0%). Five-year overall and disease-free survival rates were 30.2 and 27.5%, respectively. At multivariate analysis the strongest poor prognostic factor for overall survival was tumor stage. This factor, with multiplicity of lesions (≥ 4) and tumor grading > 2, was significant predictor of recurrence. CA19-9 > 100 IU/mL and tumor grading > 2 were found to be significantly related with early multinodular hepatic recurrence. Patients with lymph node metastases had significantly lower overall and disease-free survival but patients who underwent lymph node dissection with negative lymph nodes at final pathology showed significantly higher 5-year disease-free survival than patients who did not underwent lymphadenectomy. In conclusion, these results support the role of hepatectomy with regional lymphadenectomy as the best available treatment for IHC. Prognosis after liver resection correlates with clinical stage and multiplicity of lesions.

Abstract
OBJECTIVE To develop a clinical and prognostic scoring system predictive of survival after resection of intrahepatic cholangiocarcinomas (ICC). PATIENTS Two hundred and one consecutive ICC patients (83 from Essen, Germany, 54 from New York, USA and 64 from Chiba, Japan). The scoring systems were developed utilizing the data set from Essen University and then applied to the data sets from Mount Sinai Medical Center and Chiba University for validation. Eighteen potential prognostic factors were evaluated. Statistical analysis included multivariable regression analyses with the Cox proportional hazard model, power analysis, internal validation with structural equation modelling bootstrapping and external validation. The prognostic scoring model was based mainly in pathological and demographical variables, whereas the clinical scoring model was based mainly in radiological and demographical variables. RESULTS Gender (P=0.0086), UICC stage (P=0.0140) and R-class (P=0.0016) were predictive of survival for the prognostic scoring model, while gender (P=0.0023), CA 19-9 levels (P=0.0153) and macrovascular invasion (P=0.0067) were predictive of survival for the clinical scoring model. Prognostic points were assigned as follows: female:male=1:2 points, UICC (I-II):UICC (III-IV)=1:2 points and R0:R1=1:2 points. Clinical points were allocated as follows: female:male=1:2 points, CA 19-9 (<100 U/ml):CA 19-9 (> or =100 U/ml)=1:2 points and no macrovascular invasion:macrovascular invasion=1:2 points. Prognostic groups with 3-4, 5 and 6 points (P=0.000001) and clinical groups with 3-4 and 5-6 points (P=0.0103) achieved statistically significant difference. CONCLUSIONS We propose a clinical and prognostic scoring system predictive of long-term survival after surgical resections for ICC.

Abstract
OBJECTIVE To evaluate the results of surgical therapy for intrahepatic cholangiocarcinoma (ICC), the incidence and the management of recurrence, and to analyze the change in approach during 2 different periods. DESIGN Retrospective study. PATIENTS AND METHODS Patient and tumor characteristics, and overall and disease-free survival were analyzed in a series of 72 consecutive patients who underwent hepatic resection for ICC. Several factors likely to influence survival after resection were evaluated. Patients were divided into 2 groups according to the year of operation (before and after 1999). Management of recurrence and survival after recurrence were also analyzed. RESULTS The 3- and 5-year overall survival rates were 62% and 48%, whereas the 3- and 5-year disease-free survival rates were 30% and 25%, respectively. The median survival time was 57.1 months. Patient and histologic characteristics before and after 1999 were similar. Survival was significantly better among patients operated after 1999, who were node-negative, did not receive blood transfusion, and underwent adjuvant chemotherapy. The overall recurrence rates before and after 1999 were comparable (66.6% and 50%, P = 0.49). The most frequent site of recurrence was the liver. A significantly large number of patients received treatment for recurrence after 1999 (81.5%) compared with the first period (8.3%). The overall 3-year survival rate after recurrence was 46%. After 1999, there was a significant improvement in 3-year survival after recurrence (56%) compared with patients operated before 1999 (0%, P = 0.004); the median survival time from the diagnosis of recurrence increased from 20 months to 66 months in the second group. CONCLUSIONS Although recurrence rate represents a frequent problem in ICC, an aggressive approach to recurrence can significantly prolong survival.

Abstract
BACKGROUND AND OBJECTIVES Cholangiocarcinoma can be classified as intrahepatic (ICC) or perihilar (PCC). The objectives of this study is to evaluate the surgical outcomes of patients with PCC and ICC, identify the main prognostic factors related to survival and compare the outcome and the prognostic factors of PCC and ICC. METHODS Ninety-five out of 152 patients observed between January 1990 and December 2007 at Surgical Division of University of Verona Medical School underwent the resection of ICC (33 patients) or PCC (62 patients). RESULTS Overall median survival was 24 months with a 3- and 5-year survival rate of 45% and 23%, respectively. Prognostic factors for survival were macroscopic types of the tumor, the resection of extrahepatic bile duct, radical resection, lymph node metastases, and macro-vascular invasion. Survival was related with the macroscopic type of the tumors with a 5-year survival rate of 26% and 13% for ICC and PCC, respectively. Univariate analysis identified that negative clinico-pathological factors where significant more frequently found in PCC compared to ICC. CONCLUSION We identified that ICC have longer survival rate compared to PCC. PCC showed a higher frequency of negative clinico-pathological factors such as non-radical (R+) resection, perineural infiltration and macro-vascular invasion.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy, but the studies for the outcome after resection of ICC are rare. The aim of this study was to elucidate outcomes and prognostic factors of ICC in patients undergoing hepatic resection. METHODS A retrospective study was conducted with a total of 63 patients who underwent surgical resection with curative intent for ICC. We performed the survival analysis with preoperative and postoperative clinicopathologic factors according to the clinical outcome. RESULTS The cumulative 1-, 3-, and 5-year survival rates were 68.2, 50.5, and 31.8%, respectively. Univariate analysis revealed that patient's old age, high preoperative carbohydrate antigen 19-9 (CA19-9) level, major vessel invasion, T classification, lymph node metastasis, lymphatic invasion, perineural invasion, intrahepatic metastasis, and narrow resection margin were statistically significant. By multivariate analysis, patient's old age, high preoperative CA19-9 level, lymphatic invasion, and narrow resection margin were independent dismal prognostic factors. The preoperative CA19-9 level shows a significant correlation with some histopathologic factors including major vessel invasion, bile duct invasion, and perineural invasion. CONCLUSIONS Preoperative CA19-9 level was a valuable clinical factor for predicting histopathologic invasiveness as well as clinical outcome. An adequate resection margin was the only modifiable factor by a surgeon during hepatic resection for ICC.

Abstract
BACKGROUND/AIMS This study was conducted to analyze the prognostic factors in patients with intrahepatic cholangiocarcinoma (ICC) who did not receive surgery. METHODS Between August 1997 and November 2007, the medical records of 175 patients (mean age; 66 years, male/female 126/49), who were diagnosed as ICC, were reviewed retrospectively. RESULTS Clonorchiasis and hepatolithiasis was found in 14.9%, and 6.3% of all patients, and no risk factors were identified in 77.8% of them. Surgical resection was performed in 29.1% (51 patients), chemotherapy +/- radiotherapy in 12.6% (22 patients), and palliative therapy in 58.3% (102 patients). The proportion of patients with stage I was 23.4% (41 patients). The prognostic factors in patients who did not receive surgery were alkaline phosphatase (ALP) and bilirubin levels by univariate and multivariate analysis. The median survival of patients with normal ALP and bilirubin levels was six months, whereas only one month in patients with elevated ALP and bilirubin levels (p<0.001). Tumor characteristics of patients with elevated bilirubin and ALP levels were infiltrative tumor, bile duct involvement, and very huge tumor. CONCLUSIONS The prognostic factors of ICC in patients who did not receive surgery were ALP and bilirubin levels, but not lymph node metastasis.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver tumor. The resectability rate is low because at the time of diagnosis this disease is frequently beyond the limits of surgical therapy. Curative resection (R0) is the most effective treatment and the only therapy associated with prolonged disease-free survival. Based on the gross appearance of the tumor the Liver Cancer Study Group of Japan (LCSGJ) defined three types: mass-forming type (MF), periductal infiltrating type (PI), intraductal growth (IG) type. The prognostic significance of gross type has been demonstrated in Eastern countries, but this issue has not been clarified in Western countries. The aim of this study was to identify the prognostic factors for survival in a group of patients submitted to surgical resection for ICC. METHODS Between 1990 and 2007 a total of 81 consecutive patients with ICC were submitted to surgery. Patients with peritoneal carcinomatosis, extensive vascular involvement, or multiple intrahepatic metastases were excluded from surgical resection. Tumors were classified according to TMN stage (6th edition, 2002) and LCSGJ gross type classification. Tumor gross appearance on the cut surface was categorized into the following types according to the classification proposed by the Liver Cancer Study Group of Japan: MF, PI, or IG type. RESULTS During the study period 52 patients were submitted to surgical resection with curative intent, whereas in 29 patients surgery was limited to explorative laparotomy. Curative resection (R0) was achieved in 43 patients (83%); and a major hepatic resection was performed in 63% (33/52) of the patients. Extrahepatic bile duct resection was carried out in 36% (19/52) of cases. According to the LCSGJ classification, the MF type was present in 34 patients (65%), the MF + PI type in 13 (25%), the PI type in 3 (6%), and the IG type in 2 (4%). Overall median survival time was 40 months, with a 1-, 3-, and 5-year actuarial survival rates of 83%, 50%, 20%, respectively. Survival was significantly related to the macroscopic gross type, with a median survival of 50 months for patients with the MF type, 19 months for the MF + PI type, 15 months for the PI type, and 17 months for the IG type. At univariate analysis, the macroscopic gross appearance of the tumor, the presence of lymph node metastasis, involvement of extrahepatic bile ducts, the presence of macroscopic vascular invasion, and positive resection margins were significant related to survival. At multivariate analysis, macroscopic vascular invasion and lymph nodes metastases were significant related to survival with hazard ratios of 4.11 and 2.79, respectively. Further statistical analyses were carried out to identify the relation between macroscopic gross type and prognosis. We identified that the MF + PI type tumors were significantly associated with negative prognostic factors, such as the involvement of extrahepatic bile ducts, the presence of lymph nodes metastases, the presence of macroscopic vascular invasion, the presence of perineural invasion, and higher T stage. CONCLUSIONS Curative resection of ICC is the only therapy that can achieve long-term survival. The best results were observed in patients who underwent R0 resection for MF tumors without lymph node metastases or vascular invasion. Important predictive factors related to poor survival are MF + PI macroscopic tumor type, lymph node metastases, and vascular invasion. In these patients, other therapeutic approaches (i.e., adjuvant or neoadjuvant therapy) should be evaluated to improve results.

Abstract
BACKGROUND Primary liver cancer constitutes an increasingly malignancy in the Western world and one of the leading causes of cancer-related deaths worldwide. The purpose of this study was to evaluate and compare long-term outcomes after R0 resections in noncirrhotic livers for hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). METHODS Between April 1998 and May 2006 a total of 102 patients with either ICC (n = 41, group 1) or HCC (n = 61, group 2) in the absence of cirrhosis underwent curative liver resection in our department. Demographic characteristics, operative details, perioperative complications, pathologic findings, tumor recurrence and survival were analyzed. RESULTS Gender (P = 0.007), extent of liver resection (P = 0.036), additional surgical procedures (P < 0.001) and operative morbidity (P = 0.018) differed among the two groups. Following resection, after a median follow-up of 28 months, the calculated 5-year survival was 44% and 40% for ICC and HCC, respectively (P = 0.38). The corresponding recurrence-free survival was 25% for both ICC and HCC (P = 0.66). UICC stage was found to predict overall and recurrence-free survival in both types of tumors. Multifocality in the case of ICC, and tumor differentiation and vascular invasion in the case of HCC, were predictive factors for overall and recurrence-free survival, respectively. In multivariable analyses, vascular invasion for HCC was predictive for overall and recurrence-free survival, whereas in the case of ICC significant differences were detected in the recurrence analysis for multifocality and UICC stage. CONCLUSIONS R0 resections for both ICC and HCC result to similar long-term outcomes, which are characterized by good overall and acceptable recurrence-free survival rates.

Abstract
BACKGROUND Intrahepatic cholangiocarcinoma (ICC) is a rare primary liver malignancy. Until now, outcomes and prognostic factors after liver resection for these tumors have not been well-documented. STUDY DESIGN Between April 1998 and December 2006, a total of 158 patients underwent surgical exploration in our institution for intended liver resection of ICC. Prospectively collected data of patients undergoing liver resection (n = 83) were analyzed with regard to preoperative findings, operative details, perioperative morbidity and mortality, pathologic findings, outcomes measured by tumor recurrence and survival, and prognostic factors for outcomes. RESULTS Tumors were solitary in 47 patients. R0 resections were achieved in 53 patients. Vascular infiltration and lymph node metastasis were detected in 41% and 34%, respectively. After resection, the calculated 1-, 3-, and 5-year-survival rates were 71%, 38%, and 21%, respectively, with corresponding rates of 83%, 50%, and 30% in R0 resections. For 14 variables evaluated, only gender (p = 0.008), Union Internationale Contre le Cancer stage (p = 0.014), and R classification (p = 0.001) showed predictive value in the multivariate Cox proportional hazard regression. CONCLUSIONS Results presented outline that an R0 resection leads to substantially prolonged survival in ICC and represents the considerable input of the surgeon to the outcomes of these patients. Union Internationale Contre le Cancer stage remains an important factor.

Abstract
BACKGROUND Routine and radical lymph node dissection is a clinical concern for improving the surgical outcome in patients with intrahepatic cholangiocarcinoma (ICC). The therapeutic value of the procedure during hepatectomy has, however, not been evaluated. METHODS Between January 1990 and December 2004, 104 patients with ICC undergoing macroscopic curative resections were investigated retrospectively with special reference to lymph node status. The role of lymph node dissection was evaluated according to macroscopic type: mass-forming (MF) type (n = 68) and MF plus periductal infiltration (PI) type (n = 36) of ICC. RESULTS Lymph node involvement and intrahepatic metastases were an independent, unfavorable prognostic factor in the MF type of ICC. Negative lymph node involvement provided a favorable survival rate in the 41 patients without intrahepatic metastases (P < .0001). Among the 29 patients without lymph node involvement and intrahepatic metastases, there was no difference according to the use of lymph node dissection (P = .8071). Also, no difference was seen with lymph node involvement in the 24 patients with the MF plus PI type of ICC who had no intrahepatic metastases (P = .6620). CONCLUSION For purpose of diagnostic staging and exclusion of positive regional lymph nodes, lymph node dissections might be useful in patients with the MF type and the MF plus PI type of ICC; however, routine use of lymph node dissection in patients with the MF type of ICC is not recommended, because no difference in survival was observed in the patients with negative lymph node metastases, irrespective of the use of lymph node dissection.

Abstract
Cholangiocarcinoma is a primary hepatic malignancy originating from bile duct epithelium. It is the second most common primary hepatic neoplasia, and its incidence has increased within the last 3 decades. Although several risk factors have been identified, especially chronic biliary tract inflammation, most patients with cholangiocarcinoma have no identifiable risk factors. Recent developments in radiologic and molecular diagnostic methods have helped in the diagnosis of this disease. The only curative therapy is surgical resection or liver transplantation. For patients with advanced stage disease, survival remains limited. With growing understanding of the molecular and cellular etiology of this disease, new targeted therapies are being developed.

Abstract
BACKGROUND The purpose of this study was to clarify the clinicopathologic characteristics and surgical outcomes of patients with the mass-forming (MF) plus periductal infiltrating (PI) type of intrahepatic cholangiocellular carcinoma (ICC). METHODS Between January 1, 1998, and December 31, 2004, a total of 94 patients with ICC underwent macroscopic curative resection, and the macroscopic type of the tumors was assessed prospectively. Among the 74 patients with the MF type (n = 46) and the MF plus PI type (n = 28) of ICC, multivariate analysis was conducted to identify the potential prognostic factors. The clinicopathologic data of the two groups were compared. RESULTS The results revealed two independent prognostic factors: presence/absence of intrahepatic metastasis and the macroscopic type of the tumor. ICCs categorized macroscopically as the MF plus PI type were significantly associated with jaundice (p < 0.001), bile duct invasion (p < 0.001), portal vein invasion (p = 0.025), lymph node involvement (p = 0.017), and positive surgical margin (p = 0.038). CONCLUSION Identification of the macroscopic type of the tumor is useful for predicting survival after hepatectomy in patients with ICC. The MF plus PI type of ICC appears to have a more unfavorable prognosis, even after radical surgery, than the MF type of ICC.

Abstract
Cholangiocarcinoma is the second most common hepatobiliary tumour. Even if it is a rare tumour, its incidence is increasing over these last decades, probably due in part to a better knowledge of the disease and to an improvement of the diagnosis. Accurate diagnosis and staging are key steps to determine the appropriate treatment. The only curative treatment of this cancer is surgical resection. To date, no neoadjuvant or adjuvant treatments have ever proved any survival benefit, and are not recommended outside clinical trials. Liver transplantation (with or without neoadjuvant treatment) can be an option for highly selected cases. Unfortunately, these tumours are generally diagnosed at an advanced stage or are unresectable. For most of these patients, palliative therapeutic options exist and are in further development, based on multimodal promising combinations including chemotherapy, targeted agents, radiation, endoscopic stenting and photodynamic treatment.

Abstract
BACKGROUND Cholangiocarcinoma (CCA) is associated with poor survival and therapeutic nihilism. To date, there has not been an examination of the surgical management of CCA at a population level. METHODS Using the Surveillance, Epidemiology and End Results (SEER) database, we identified all patients with intrahepatic CCA diagnosed between 1988 and 2003. Tumors categorized as a single, unilobar lesion with no evidence of vascular invasion were defined as localized. It was then determined whether patients received cancer directed surgery (CDS). Multivariable logistic regression was used to evaluate factors associated with CDS in patients with localized disease. The influence of CDS on overall survival (OS) was evaluated using Kaplan-Meier curves and Cox proportional hazards modeling. RESULTS Only 446 (12%) of 3,756 patients with intrahepatic CCA underwent CDS. On multivariable analysis, non-Klatskin tumor (p < 0.01) and younger age (p = 0.02) was associated with CDS. Localized disease was strongly associated with CDS (p < 0.01); however, only 91 (37%) of these 248 patients underwent CDS. Of patients with localized disease, those who had CDS had significantly better survival than those who did not (p < 0.01), with median overall survival (OS) of 44 months versus 8 months, and five-year OS of 42% versus 4%, respectively. CONCLUSIONS Patients with localized CCA who are selected for CDS are strongly associated with improved survival, with rates approaching that found in single institution studies. However, many patients with localized tumors do not receive potentially curative cancer-directed surgery. Further study is warranted to address the barriers to the delivery of appropriate care to these patients.

Abstract
BACKGROUND AND OBJECTIVES The clinical impact of the surgical margin status in macroscopic curative hepatectomy for intrahepatic cholangiocarcinoma (ICC) has not yet been fully investigated. METHODS The data of 57 consecutive patients with mass-forming (MF) type ICC who underwent macroscopic curative hepatectomy during a 10-year period were retrospectively examined, and the relationship between the surgical margin status and patient survival was analyzed. RESULTS Lymph node metastases were found to be independently associated with poor survival. The overall 5-year survival rates and the median survival term in the 38 patients without lymph node metastases were 56.8% and 62 months, respectively. Among these 38 patients, the survival rate was better in the negative surgical margin group as compared with that in the positive surgical margin group. However, there was no statistically significant difference between the narrow and wide surgical margin groups. CONCLUSIONS Negative surgical margin had a definite favorable impact on the survival of patients with a solitary ICC without lymph node metastases. Surgery should be conducted in patients without lymph node metastases even if a wide surgical margin cannot be obtained, but careful attention should be paid not to expose tumors during hepatic dissection.

Abstract
Cholangiocarcinomas are tumors that arise anywhere in the biliary tract, presumably of cholangiocyte origin. The global incidence of this rare disease is on the rise. Several known risk factors exist, and link chronic biliary inflammation to the pathogenesis of cholangiocarcinoma. Among these, amplification of the epidermal growth factor receptor, the interleukin-6 signaling pathway, inducible nitric oxide, erb-2, and cyclooxygenase-2 are well defined. Most patients present late, with a median survival of months. Although, imaging studies and clinical context often indicate cholangiocarcinoma, pathologic and cytologic diagnosis is difficult to obtain. Advanced cytologic tests with fluorescence in situ hybridization or digital image analysis can increase diagnostic sensitivity. Surgical resection is the current therapy of choice for both intrahepatic and ductal cholangiocarcinomas. However, the 5-year survival is poor, with 60 to greater than 90% recurrence rates. In a single center experience, liver transplantation with neoadjuvant chemoirradiation, for highly selected patients, has a 5-year disease free survival of greater than 80%. Future targeted therapies will depend on a better understanding of the cellular and molecular biology of cholangiocarcinomas.

Abstract
INTRODUCTION Peripheral cholangiocarcinoma (PC) is an uncommon primary hepatic tumor that represents 10% of hepatic resections for primary malignant tumors in our experience. PATIENTS AND METHODS From 1988 to 2004, 29 patients with a diagnosis of PC were treated in our unit. One patient was treated with chemoembolization and the remainder underwent surgery. In 7 patients, hepatectomy was not performed due to the presence of an extrahepatic tumor or massive hepatic invasion. The resectability index was 75%. Twenty-one patients underwent radical excision of PC and comprised the study group. RESULTS The mean age was 60 years with a slight predominance of women. Sixty-two patients were symptomatic and tumoral markers were elevated in 58%. PC developed in normal liver in 15 patients, in cirrhotic liver in 2 patients and in the context of chronic hepatitis in 4 patients. The mean tumoral size was 7 cm (between 1.6 and 13 cm). Multiple tumors were found in 3 patients, invasion of the hepatic hilum lymph nodes was found in 8 patients and vascular invasion was observed in a further 8 patients. Major hepatectomy was performed in 90% of the patients; radical lymphadenectomy of the hepatic hilum was performed in 15 patients and excision of the extrahepatic biliary tract followed by Roux-en-Y hepaticojejunostomy in 4 patients. Operative mortality occurred in 3 patients (14%); one cirrhotic patient died 4 days after surgery from cardiovascular causes and 2 patients died from liver failure after extensive hepatectomies that included resection of the inferior vena cava and suprahepatic veins. Complications occurred in 33% of the patients. Ten patients (47%) died. Of these, 6 died from tumoral recurrence. Tumoral recurrence occurred in 9 patients (5 hepatic and 4 extrahepatic). Hepatic recurrences were treated with radiofrequency ablation in 2 patients and chemotherapy in 5 patients. The median survival was 11 months. Actuarial survival at 1, 3 and 5 years was 60%, 47% and 47% respectively. Disease-free survival at 1, 3 and 5 years was 50%, 31% and 31% respectively. In univariate analysis, significant risk factors for mortality were lymphatic invasion and a resection margin of less than 1 cm. In multivariate analysis, negative factors for tumoral recurrence were lymphatic invasion, satellitosis, and poor tumoral delimitation. CONCLUSION Surgical treatment of PC through radical hepatic resection with margins of more than 1 cm in patients without nodal invasion provides good results with a 5-year survival of 79%.

Abstract
BACKGROUND/PURPOSE The Liver Cancer Study Group of Japan established a tumor-nodule-metastasis (TNM) staging system for mass-forming intrahepatic cholangiocarcinoma, with T determined by tumor number and size and vascular or serosal invasion. Serosal invasion is not considered in the designation established by the International Union Against Cancer. METHODS Sixty-three patients who underwent hepatic resection for mass-forming intrahepatic cholangiocarcinoma were investigated retrospectively, with the investigation including univariate and multivariate analyses of potential prognostic factors. RESULTS By log-rank test, tumor size more than 3.0 cm, vascular invasion, lymph node metastasis, intrahepatic metastasis, and involved resection margin, but not serosal invasion, were associated significantly with poor prognosis. Even in patients with serosal invasion, the postoperative outcome was much better in those without than in those with vascular invasion. Multivariate analysis identified vascular invasion, lymph node metastasis, and an involved resection margin as independent prognostic factors. When serosal invasion was excluded from tumor staging, the 5-year survival rates became more clearly stratified: 100% in those with stage I disease, 62% in those with stage II, 25% in those with stage III, and 7% for patients with stage IV. CONCLUSIONS Serosal invasion showed no survival impact after hepatic resection for mass-forming intrahepatic cholangiocarcinoma. When serosal invasion was omitted from the TNM staging proposed by the Liver Cancer Study Group of Japan, stratification of postoperative survival between stages was more effective.

Abstract
With the introduction of spiral computed tomography and the development of novel imaging technology in recent years, multidetector-row computed tomography (MDCT) has increasingly been used for the diagnosis of various lesions, especially hepatocellular carcinoma (HCC), due to its volume acquisitions, short scanning time, and especially its double-phase scanning nature, which takes advantage of the dual blood supply of liver. Multidetector-row computed tomography is used to classify HCC into several types based on the blood supply and the histological characteristics of HCC. The evaluation of HCC by MDCT provides crucial clues for the doctors to adopt correct clinical management strategies such as the selection of the appropriate dose of lipiodol before transcatheter arterial chemoembolization (TACE) and the prediction of the prognosis of HCC after TACE. The MDCT scanning allows doctors to choose the region of interest and to evaluate the blood supply according to the lipiodol uptake in order to decide whether there is recrudescence and whether a repeated therapy should be taken. This review describes MDCT, its biphasic scanning, its evaluation of blood supply in HCC and the subsequent classification of HCC, its therapeutic significance before TACE and the prognostic value after TACE.

Abstract
Cholangiocarcinomas are epithelial neoplasms that originate from cholangiocytes and can occur at any level of the biliary tree. They are broadly classified into intrahepatic tumours, (extrahepatic) hilar tumours and (extrahepatic) distal bile duct tumours. In spite of well-understood predispositions, most cholangiocarcinomas arise in the absence of risk factors. In suspected cases, the diagnosis can be established with non-invasive imaging studies. Biliary invasion should be reserved for patients with obstruction. In high-risk patients, advanced cytological tests of aneuploidy (digital image analysis and fluorescent in situ hybridization) aid early diagnosis. In the absence of primary sclerosing cholangitis, curative surgical resection has 5-year survival rates of 2-43%, higher survival observed in patients with clear surgical margins and concomitant hepatic resection for hilar tumours. Patients with unresectable cholangiocarcinoma or pre-existing primary sclerosing cholangitis should be considered for liver transplantation with neoadjuvant chemoirradiation, in specialized centres.

Abstract
PURPOSE We investigated the role of intraoperative iodine-125 (125I) brachytherapy as a treatment option for unresectable primary and metastatic liver tumors. METHODS AND MATERIALS Between 1989 and 2002, 64 patients with unresectable or residual disease after surgical resection for intrahepatic malignancies underwent 160-Gy permanent 125I brachytherapy. RESULTS The median length of follow-up was 13.2 years. The overall 1-year, 3-year, and 5-year actuarial intrahepatic local control rates were 44%, 22%, and 22%, respectively, with a median time to liver recurrence of 9 months (95% CI, 6-12 months). The 5-year actuarial intrahepatic control was higher for patients with solitary metastasis (38%) than for those with multiple metastases (6%, p = 0.04). The 1-year, 3-year, and 5-year actuarial overall survival rates were 73%, 23%, and 5%, respectively (median, 20 months; 95% CI, 16-24; longest survival, 7.5 years). Overall survival was higher for patients with smaller-volume implants (p = 0.003) and for patients without prior liver resection (p = 0.002). No mortality occurred. Radiation-related complications were minimal. CONCLUSIONS For select patients with unresectable primary and metastatic liver tumors for whom curative surgical resection is not an option, 125I brachytherapy is a safe and effective alternative to other locally ablative techniques and can provide long-term local control and increased survival.

Abstract
BACKGROUND Treating intrahepatic cholangiocarcinoma (ihCCC) tumor resection leads to the best patient survival. The aim of this study was to investigate prognostic factors in resected patients. METHODS This was a clinical observational series of 31 resected patients with ihCCC. Univariate analysis of clinical and pathologic factors in relation to patient survival and tumor recurrence were performed. Possible benefit of chemotherapy, although not given randomly, was investigated separately. RESULTS The median follow-up time was 37.3 months. Of 31 resected patients a tumor-free resection (R0) was achieved in 26; 2 patients died postoperatively. Chemotherapy was administered to 19 patients. Overall survival was significantly better in patients with R0 resection, negative lymph nodes, a solitary tumor, and a width of resection margin greater than 3 mm. Recurrence-free survival was prolonged in patients with negative lymph nodes, early International Union Against Cancer (UICC) stages and solitary tumors. In UICC stages III and IV, patients receiving chemotherapy experienced a better overall survival. CONCLUSIONS Impact of various parameters on recurrence-free and overall survival was identified; a possible beneficial effect of adjuvant chemotherapy in advanced tumor stages was observed. A prospective, randomized trial is necessary to fully evaluate the role of adjuvant therapy.

Abstract
OBJECTIVE To evaluate the role of extended hepatectomy in locally advanced intrahepatic cholangiocarcinoma (ICC). SUMMARY BACKGROUND DATA ICC is a rare tumor which has to be clearly distinguished from hepatocellular carcinoma and extrahepatic bile duct carcinoma. It is believed that long-term survival can only be achieved by surgical resection. METHODS Between April 1998 and March 2003, 50 patients with locally advanced ICC (tumor involvement of more than 4 liver segments) underwent surgical exploration. Data were analyzed with regard to patients' characteristics, intraoperative details, pathologic findings, and outcome measured by tumor recurrence, treatment of recurrence, and survival. RESULTS Resectability rate was 27 of 50 (54%). There were 19 extended right and 8 extended left hepatectomies. In addition, in 16 patients the following 29 procedures were performed: resection of hilar bifurcation (n = 12), partial resection of diaphragm (n = 6), partial resection of vena cava (n = 4), resection and reinsertion of left liver vein (n = 1), portal vein resection (n = 5), resection and reconstruction of right hepatic artery (n = 1). Complete tumor removal (R0-resection) was achieved in 16 patients. In 11 cases, there was microscopic tumor at the cutting margin (R1-resection). Following resection, the overall 1- and 3-year-survival rates were 69% and 55%. After R1-resection and explorative laparotomy, median survival was 5 and 7 months, respectively. Following R0-resection, the calculated median survival and 1- and 3-year-survival rates are 46 months, 94% and 82% (P = 0.0039; log-rank test). Tumor recurred in 6 of 16 patients, and so far 2 patients died of recurrence 28 and 46 months after operation. CONCLUSIONS R0-resection can provide prolonged survival, even in patients with advanced ICC. In particular in solitary tumors without vascular invasion (UICC stage I, sixth classification) there is a major chance for long-term survival and cure. The poor results after R1-resection and the high operative morbidity do not justify palliative resections but underline the need for an improved preoperative assessment of resectability, as well as an aggressive intraoperative approach, to achieve complete tumor resection.

Abstract
BACKGROUND The aim of this study was to clarify prognostic factors and recurrence patterns in patients with node-negative intrahepatic cholangiocarcinoma (IHCC). METHODS A retrospective study was performed to review prognostic factors and recurrence patterns (1) in 22 patients with node-negative IHCC after curative hepatic resection and (2) in 49 patients who underwent resection and lymph node dissection for IHCC. In addition to determining the clinicopathologic factors, the investigators also performed immunohistochemical examination of microvessel counts using antihuman CD-31 and antibody. RESULTS The significant poor prognostic factors in node-negative IHCC were the presence of intrahepatic metastasis, portal vein invasion of cancer cells, and high microvessel counts. After multivariate analysis was conducted, the independent poor prognostic factors were the presence of intrahepatic metastases and high microvessel counts. Of 9 patients who had postoperative recurrence of their disease, intrahepatic recurrence was observed in 7 (78 %). CONCLUSIONS The factors linked to poor prognosis in IHCC were tumor angiogenesis and the presence of intrahepatic metastasis. Because intrahepatic recurrence was common, regional and adjuvant chemotherapy to the liver may improve the outcome of patients with these risk factors and node-negative IHCC.

Abstract
BACKGROUND The outcome after surgery for intrahepatic cholangiocarcinoma (ICC) is dismal and data on long-term survival are not available. This study evaluated prognostic indicators and characteristic features of long-term survivors after hepatic resection for ICC. METHODS Thirty-one patients who had undergone hepatic resection for ICC were studied. Univariate and multivariate survival analyses of clinicopathological data included an intraductal papillary carcinoma component (IDPCC) in the tumour, which was defined as the histological demonstration of cancer cells growing in a papillary fashion into the lumen of the large bile duct. RESULTS The overall cumulative survival rate after hepatic resection for ICC was 51.2 per cent at 1 year and 24.5 per cent at 5 years, with a mean(s.d.) survival time of 11(4) months. The presence of IDPCC (P = 0.003), curative resection (P = 0.009) and the absence of perineural invasion (P = 0.040) were identified as favourable independent prognostic factors in multivariate analysis. Eight patients with IDPCC had a 5-year survival rate of 87.5 per cent and a mean(s.d.) survival time of 69(13) months. All seven patients who survived for more than 5 years after surgery had IDPCC, regardless of the gross appearance of the tumour. CONCLUSION An IDPCC in the tumour resulted in long-term survival after hepatic resection for ICC.

Abstract
Bismuth type IV hilar cholangiocarcinoma (CC) carries a poor prognosis; however, ex vivo liver resection and autotransplantation (Atx) is theoretically a treatment option. There are only five previously reported cases of this procedure for hilar CC in the English literature, and most of them died early in the postoperative period. The only reported survivor died of tumor recurrence at 13 months. We are reporting a patient who has survived for 17 months without any sign of tumor recurrence. This probably represents the world's first cure for CC using this technique. This patient is a 26-year-old woman with a Bismuth Type IV CC. Portal vein involvement at the confluence was shown on angiogram, and in situ resection was deemed impossible. Ex vivo resection of segments five, six, seven, eight, and part of segment four was performed followed by a partial liver Atx. The pathology specimen demonstrated CC with clear margins. MRI and CT examinations done over the subsequent 17 months showed no evidence of recurrence. In conclusion ex vivo liver resection and Atx can be a viable option for cure among highly selected patients with CC.
