Project description:ImportanceAlthough surgery offers the best chance of a potential cure for patients with localized, resectable intrahepatic cholangiocarcinoma (ICC), prognosis of patients remains dismal largely because of a high incidence of recurrence.ObjectiveTo predict very early recurrence (VER) (ie, recurrence within 6 months after surgery) following resection for ICC in the pre- and postoperative setting.Design, setting, and participantsPatients who underwent curative-intent resection for ICC between May 1990 and July 2016 were identified from an international multi-institutional database. The study was conducted at The Ohio State University in collaboration with all other participating institutions. The data were analyzed in December 2019.Main outcomes and measuresTwo logistic regression models were constructed to predict VER based on pre- and postoperative variables. The final models were used to develop an online calculator to predict VER and the tool was internally and externally validated.ResultsAmong 880 patients (median age, 59 years [interquartile range, 51-68 years]; 388 women [44.1%]; 428 [50.2%] white; 377 [44.3%] Asian; 27 [3.2%] black]), 196 (22.3%) developed VER. The 5-year overall survival among patients with and without VER was 8.9% vs 49.8%, respectively (P < .001). A preoperative model was able to stratify patients relative to the risk for VER: low risk (6-month recurrence-free survival [RFS], 87.7%), intermediate risk (6-month RFS, 72.3%), and high risk (6-month RFS, 49.5%) (log-rank P < .001). The postoperative model similarly identified discrete cohorts of patients based on probability for VER: low risk (6-month RFS, 90.0%), intermediate risk (6-month RFS, 73.1%), and high risk (6-month RFS, 48.5%) (log-rank, P < .001). The calibration and predictive accuracy of the pre- and postoperative models were good in the training (C index: preoperative, 0.710; postoperative, 0.722) as well as the internal (C index: preoperative, 0.715; postoperative, 0.728; bootstrapping resamples, n = 5000) and external (C index: postoperative, 0.672) validation data sets.Conclusion and relevanceAn easy-to-use online calculator was developed to help clinicians predict the chance of VER after curative-intent resection for ICC. The tool performed well on internal and external validation. This tool may help clinicians in the preoperative selection of patients for neoadjuvant therapy as well as during the postoperative period to inform surveillance strategies.

Project description:Intrahepatic cholangiocarcinoma (iCCA) is a rare and aggressive primary liver tumor, characterized by a range of different clinical manifestations and by increasing incidence and mortality rates even after curative treatment with radical resection. In recent years, growing attention has been devoted to this disease and some evidence supports liver transplantation (LT) as an appropriate treatment for intrahepatic cholangiocarcinoma; evolving work has also provided a framework for better understanding the genetic basis of this cancer. The aim of this study was to provide a clinical description of our series of patients complemented with Next-Generation Sequencing genomic profiling. From 1999 to 2021, 12 patients who underwent LT with either iCCA or a combined hepatocellular and cholangiocellular carcinoma (HCC-iCCA) were included in this study. Mutations were observed in gene activating signaling pathways known to be involved with iCCA tumorigenesis (KRAS/MAPK, P53, PI3K-Akt/mTOR, cAMP, WNT, epigenetic regulation and chromatin remodeling). Among several others, a strong association was observed between the Notch pathway and tumor size (point-biserial rhopb = 0.93). Our results are suggestive of the benefit potentially derived from molecular analysis to improve our diagnostic capabilities and to devise new treatment protocols, and eventually ameliorate long-term survival of patients affected by iCCA or HCC-iCCA.

Project description:Background:Liver resection is the only curative therapeutic option for intrahepatic cholangiocarcinoma (ICC), but the approach to recurrent ICC is controversial. This study analysed the outcome of liver resection in patients with recurrent ICC. Methods:Demographic, radiological, clinical, operative, surgical pathological and follow-up data for all patients with a final surgical pathological diagnosis of ICC treated in a tertiary referral centre between 2001 and 2015 were collected retrospectively and analysed. Results:A total of 190 patients had liver resection for primary ICC. The 1-, 3- and 5-year overall survival (OS) rates were 74·8, 56·6 and 37·9 per cent respectively. Independent determinants of OS were age 65 years or above (hazard ratio (HR) 2·18, 95 per cent c.i. 1·18 to 4·0; P = 0·012), median tumour diameter 5 cm or greater (HR 2·87, 1·37 to 6·00; P = 0·005), preoperative biliary drainage (HR 2·65, 1·13 to 6·20; P = 0·025) and local R1-2 status (HR 1·90, 1·02 to 3·53; P = 0·043). Recurrence was documented in 87 patients (45·8 per cent). The mean(s.d.) survival time after recurrence was 16(17) months. Independent determinants of recurrence were median tumour diameter 5 cm or more (HR 1·71, 1·09 to 2·68; P = 0·020), high-grade (G3-4) tumour (HR 1·63, 1·04 to 2·55; P = 0·034) and local R1 status (HR 1·70, 1·09 to 2·65; P = 0·020). Repeat resection with curative intent was performed in 25 patients for recurrent ICC, achieving a mean survival of 25 (95 per cent c.i. 16 to 34) months after the diagnosis of recurrence. Patients deemed to have unresectable disease after recurrence received chemotherapy or chemoradiotherapy alone, and had significantly poorer survival. Conclusion:Patients with recurrent ICC may benefit from repeat surgical resection.

Project description:Aim: We aimed to compare the survival outcomes of radiofrequency ablation (RFA) and surgical resection (SR) for patients with small early-stage primary intrahepatic cholangiocarcinoma (ICC). Methods: Patients with small (≤5 cm) and early-stage ICC were screened from the Surveillance, Epidemiology, and End Results (SEER) database. Overall survival (OS) and cancer-specific survival (CSS) rates between the SR and RFA patients were evaluated. The results were verified using an inverse probability-weighting model (IPTW). Results: In total, 184 patients with small T1 stage ICC that received RFA or SR treatment were identified. The OS rates at 1, 3, and 5 years were 87.4, 73.3, and 61.5% for patients who underwent SR, respectively, and 89.9, 42.4, and 23.9%, respectively, for patients who received RFA. CSS rates at 1, 3, and 5 years were 91.5, 73.8, and 66.1%, respectively, for the SR group and 93.5, 53.4, and 30.0%, respectively, for the RFA group. The OS and CSS rates were evaluated to be significantly better in the SR group than in the RFA group after the multivariate Cox regression and IPTW analysis. Subsequently, the survival benefit of SR was also observed in the subgroup of patients with <4.5 or <4 cm early-stage ICC when compared with RFA. Conclusion: Our results indicated that the SR provided a significantly better prognosis than RFA in patients with small and early-stage ICC. SR as the first-line treatment of primary early-stage ICC is still recommended. However, prospective randomized controlled trials with larger sample sizes are required to compare these modalities in the treatment of ICC.

Project description:Intrahepatic cholangiocarcinoma (ICC) is a rare, aggressive cancer of the biliary tract. It often presents with locally advanced or metastatic disease, but for patients with early-stage disease, surgical resection with negative margins and portahepatis lymphadenectomy is the standard of care. Recent advancements in ICC include refinement of staging, improvement in liver-directed therapies, clarification of the role of adjuvant therapy based on new randomized controlled trials, and advances in minimally invasive liver surgery. In addition, improvements in neoadjuvant strategies and surgical techniques have enabled expanded surgical indications and reduced surgical morbidity and mortality. However, recurrence rates remain high and more effective systemic therapies are still necessary to improve recurrence-free and overall survival. In this review, we focus on current and emerging surgical principals for the management of ICC including preoperative evaluation, current indications for surgery, strategies for future liver remnant augmentation, technical principles, and the role of neoadjuvant and adjuvant therapies.

Project description:Partial hepatectomy is a potentially curative therapy for intrahepatic cholangiocarcinoma (ICC). Unfortunately, the overall surgical prognosis remains dismal and the actual 10-year survival has not been reported. This study aimed to document 10-year actual survival rates, identify the prognostic factors associated with 10-year survival rate, and analyze the characteristics of patients who survived ? 10 years. Among 251 patients who underwent curative liver resection for ICC between 2003 and 2006 at the Eastern Hepatobiliary Surgery Hospital, 21 patients (8.4%) survived ? 10 years. The 5-, 7-, and 10-year overall survival rates were 32.3%, 22.3% and 8.4%, respectively. The 10-year cumulative incidence of ICC-related death and recurrence were 80.9% and 85.7%, respectively. Multivariate analysis based on competing risk survival analysis identified that tumor > 5 cm was independently associated with ICC-related death and recurrence (hazard ratios: 1.369 and 1.445, respectively), in addition to carcinoembryonic antigen (CEA) >10 U/mL, carbohydrate antigen 19-9 (CA19-9) >39 U/mL, multiple nodules, vascular invasion, nodal metastasis and local extrahepatic invasion. Patients who survived ? 10 years had a longer time to first recurrence, lower levels of CEA, CA19-9 and alkaline phosphatase, less perioperative blood loss, solitary tumor, smaller tumor size, and absence of nodal metastasis or local extrahepatic invasion. In conclusion, a 10-year survival after liver resection for ICC is possible and can be expected in approximately 8.4% of patients.

Project description:BackgroundThe effectiveness of adjuvant transarterial chemoembolization (TACE) for intrahepatic cholangiocarcinoma (ICC) after hepatectomy remains unclear. This study was performed to identify ICC patients who would benefit from adjuvant TACE.Patients and methodsThe study included 553 patients who underwent hepatectomy for ICC between January 2008 and February 2011 at the Eastern Hepatobiliary Surgery Hospital and who were treated with or without TACE (122 with TACE and 431 without TACE). Survival risk stratification was performed using the established prognostic nomogram (ICC nomogram). The predictive performance was evaluated by concordance index and calibration. The tumor recurrence and overall survival (OS) rates were analyzed by the Kaplan-Meier method before and after propensity score matching (PSM).ResultsThe predictive performance of the ICC nomogram was demonstrated by the well-fitted calibration curves and an optimal c-index of 0.71 for OS prediction. In the whole cohort, the 5-year recurrence and OS rates between the TACE and non-TACE groups were significantly different (5-year recurrence: 72.9% vs. 78.1%; OS: 38.4% vs. 29.7%). After 1:1 PSM, the TACE and non-TACE groups (122 patients each) had similar 5-year recurrence and OS rates (5-year recurrence: 72.9% vs. 74.2%; OS: 38.4% vs. 36.0%). By survival risk stratification based on ICC nomogram, only the patients in the lowest tertile (nomogram scores ?77) benefited from adjuvant TACE (TACE vs. non-TACE groups: 90.4% vs. 95.9% for 5-year recurrence; 21.3% vs. 6.2% for 5-year OS).ConclusionAdjuvant TACE following liver resection might be suitable for ICC patients with high ICC nomogram scores (?77).Implications for practiceThe accurate predictive performance of the established prognostic nomogram for intrahepatic cholangiocarcinoma (ICC) following liver resection was reconfirmed in an independent cohort with 553 patients. Based on the survival risk stratification using the nomogram, adjuvant transarterial chemoembolization following liver resection might be suitable only for ICC patients with high scores from the nomogram.

Project description:BackgroundAlthough laparoscopic hepatectomy has been widely used in the treatment of benign and malignant liver diseases, its applicability in intrahepatic cholangiocarcinoma (ICC) is controversial. We conducted a meta-analysis to compare the short-term and long-term outcomes of laparoscopic hepatectomy (Lap-ICC) and open hepatectomy (Open-ICC) in ICC patients.MethodsThe PubMed, Web of science, Cochrane Library, China National Knowledge Infrastructure and other databases were searched for the relevant literature. The research data were extracted according to the inclusion and exclusion criteria.ResultsSeventeen studies, including 3975 ICC patients, were selected for the meta-analysis. Compared to Open-ICC, Lap-ICC had lower rates of lymph node dissection (OR=0.44, P=0.01) and metastasis (OR=0.58, P=0.03), along with less intraoperative bleeding (MD=-128.43 ml, P<0.01) lower blood transfusion rate (OR=0.43, P<0.01), shorter hospital stay (MD=-2.75 day, P<0.01), higher R0 resection rate (OR=1.60, P<0.01), and lower tumor recurrence rate (OR=0.67, P=0.01). However, there was no difference between the two groups in terms of operation time, number of lymph node dissection, incision margin distance, overall complications rate, severe complications rate, and the 1-, 3- and 5-year DFS and OS rates.ConclusionLaparoscopic hepatectomy is partially superior to open hepatectomy in terms of less bleeding, shorter hospital stay and higher R0 resection rate, while the long-term efficacy of the two approaches is similar.

Project description:Combined hepatocellular-cholangiocarcinoma (cHCC-CC) and intrahepatic cholangiocarcinoma (ICC) are classified into one category, but comparison of prognosis of the two carcinomas remains controversial. The aim of the current study was to investigate surgical outcomes for patients with ICC or cHCC-CC who underwent resection in order to elucidate whether the classification of ICC and cHCC-CC is justified. Subjects were 61 patients with ICC and 29 patients with cHCC-CC who underwent liver resection from 2001 to 2017. Clinic-pathological data from the two groups were compared. Tumor number and vascular invasion were independent risk factors for recurrence-free survival (RFS) in both groups (P < .001 for both). Of note, for patients with ICC, tumor cut-off size of 5 cm showed statistical significance in median RFS (>5 cm vs ?5 cm, 0.5 years vs 4.0 years, P = .003). For patients with cHCC-CC, tumor cut-off size of 2 cm showed statistical significance in median RFS (>2 cm vs ?2 cm, 0.6 years vs 2.6 years, P = .038). The median RFS of patients with cHCC-CC was 0.9 years (95% confidence interval: 0.3-1.6), which was poorer than that of patients with ICC (1.3 years, 0.5-2.1) (P = .028); the rate of RFS at 5 years was 0% and 37.7% respectively. Our study supports the concept of classifying ICC and cHCC-CC into different categories because of a significant difference in RFS between the two.

Project description:BACKGROUND:Intrahepatic cholangiocarcinoma (ICC) is often diagnosed in advanced stage. Aim of this study was to analyse the influence of resection margins and tumor distance to the liver capsule on survival and recurrence in a single center with a high number of extended resections. METHODS:From January 2008 to June 2018 data of all patients with ICC were collected and further analysed with Kaplan Meier Model, Cox regression or Chi2 test for categorical data. RESULTS:Out of 210 included patients 150 underwent curative intended resection (71.4%). Most patients required extended resections (n?=?77; 51.3%). R0-resection was achieved in 131 patients (87.3%) with minimal distances to the resection margin >?1?cm in 22, 0.5-1?cm in 11, 0.1-0.5?cm in 49 patients, and?<? 0.1?cm in 49 patients. Overall survival (OS) for margins >?0.5?cm compared to 0.5-0.1?cm or R1 was better, but without reaching significance. All three groups had significantly better OS compared to the irresectable group. Recurrence-free survival (RFS) was also better in patients with a margin >?0.5?cm than in the <?0.5-0.1?cm or the R1-group, but even without reaching significance. Different distance to the liver capsule significantly affected OS, but not RFS. CONCLUSIONS:Wide resection margins (>?0.5?cm) should be targeted but did not show significantly better OS or RFS in a cohort with a high percentage of extended resections (>?50%). Wide margins, narrow margins and even R1 resections showed a significant benefit over the irresectable group. Therefore, extended resections should be performed, even if only narrow margins can be achieved.
