"Hepatic hilum area priority, liver posterior first": An optimized strategy in laparoscopic resection for type III-IV hilar cholangiocarcinoma. World J Gastrointest Surg 2024; 16:2167-2174. [PMID: 39087123 PMCID: PMC11287698 DOI: 10.4240/wjgs.v16.i7.2167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 05/31/2024] [Accepted: 06/20/2024] [Indexed: 07/22/2024] Open
Abstract
BACKGROUND In recent years, pure laparoscopic radical surgery for Bismuth-Corlette type III and IV hilar cholangiocarcinoma (HCCA) has been preliminarily explored and applied, but the surgical strategy and safety are still worthy of further improvement and attention. AIM To summarize and share the application experience of the emerging strategy of "hepatic hilum area dissection priority, liver posterior separation first" in pure laparoscopic radical resection for patients with HCCA of Bismuth-Corlette types III and IV. METHODS The clinical data and surgical videos of 6 patients with HCCA of Bismuth-Corlette types III and IV who underwent pure laparoscopic radical resection in our department from December 2021 to December 2023 were retrospectively analyzed. RESULTS Among the 6 patients, 4 were males and 2 were females. The average age was 62.2 ± 11.0 years, and the median body mass index was 20.7 (19.2-24.1) kg/m2. The preoperative median total bilirubin was 57.7 (16.0-155.7) μmol/L. One patient had Bismuth-Corlette type IIIa, 4 patients had Bismuth-Corlette type IIIb, and 1 patient had Bismuth-Corlette type IV. All patients successfully underwent pure laparoscopic radical resection following the strategy of "hepatic hilum area dissection priority, liver posterior separation first". The operation time was 358.3 ± 85.0 minutes, and the intraoperative blood loss volume was 195.0 ± 108.4 mL. None of the patients received blood transfusions during the perioperative period. The median length of stay was 8.3 (7.0-10.0) days. Mild bile leakage occurred in 2 patients, and all patients were discharged without serious surgery-related complications. CONCLUSION The emerging strategy of "hepatic hilum area dissection priority, liver posterior separation first" is safe and feasible in pure laparoscopic radical surgery for patients with HCCA of Bismuth-Corlette types III and IV. This strategy is helpful for promoting the modularization and process of pure laparoscopic radical surgery for complicated HCCA, shortens the learning curve, and is worthy of further clinical application.

Abstract
OBJECTIVE Hilar cholangiocarcinoma (HCCA) is a highly aggressive biliary tract tumor. microRNAs (miRs) exert dual actions in various cancers. This paper seeks to expound on the functional mechanisms of miR-25-3p/dual specificity phosphatase 5 (DUSP5) in HCCA cell proliferation and migration. METHODS HCCA-related data were downloaded from GEO database to screen out differentially-expressed genes. The potential target miR (miR-25-3p) and its expression in HCCA were analyzed on Starbase. The binding relation between miR-25-3p and DUSP5 was confirmed by dual-luciferase assay. Levels of miR-25-3p and DUSP5 in FRH-0201 cells and HIBEpics were determined by RT-qPCR and Western blot. miR-25-3p and DUSP5 levels were intervened with to explore their effects on FRH-0201 cells. The apoptosis, proliferation, migration, and invasion of FRH-0201 cells were evaluated by TUNEL, CCK8, scratch healing, and Transwell assays. Flow cytometry was conducted to assess FRH-0201 cell cycle. Levels of cell cycle-related proteins were determined by Western blot. RESULTS DUSP5 was weakly-expressed and miR-25-3p was highly-expressed in HCCA samples and cells. miR-25-3p targeted DUSP5. miR-25-3p suppressed FRH-0201 cell apoptosis and increased cell proliferation, migration, and invasion. DUSP5 overexpression partially abrogated miR-25-3p overexpression-exerted effects on FRH-0201 cells. miR-25-3p stimulated G1/S phase transition of FRH-0201 cells by targeting DUSP5. CONCLUSION miR-25-3p regulated HCCA cell cycle and facilitated cell proliferation and migration by targeting DUSP5.

Abstract
Evidence regarding the optical surgical extent for Bismuth type I/II HCCA is lacking. we aims to evaluate the optimal surgical methods for Bismuth type I/II HCCA. Studies comparing bile duct resection (BDR) and BDR combined with liver resection (BDR + LR) for all types of HCCA patients were searched for analyses, and 14 studies were finally included. The main outcomes were the R0 resection rate and overall survival (OS). For all types of HCCA patents, BDR + LR resulted with higher R0 resection rates when comparing with BDR only (RR = 0.70, 95%CI, 0.63-0.78), and patients with R0 resections had eight times longer median survival and more long-time survival outcomes (3 and 5 year OS) comparing to those with non-R0 resections. Bismuth I/II HCCA patients also showed longer median survival and 3-year OS after R0 resections (P = 0.04). Moreover, there was no significant difference in 3-year OS between BDR and BDR + LR (P = 0.89) and we additionally found BDR resulted in less mortality or morbidity rates. In Europe and US, they resulted the R0 resection rates could be comparable between BDR and BDR + LR (P = 0.18), and Bismuth type I HCCA accounted for 75.8%, while in Asia, BDR + LR still resulted with higher R0 resection rates (P < 0.0001) and the Bismuth type I HCCA accounted for only 40.3%. The surgical approaches may not directly impact patient prognosis, patients with R0 resections are usually associated with improved survival outcomes; for selected Bismuth type I/II HCCA, BDR may be an acceptable option with regard to lower morbidity and comparable R0 resection rate comparing with BDR + LR.

Abstract
Hilar cholangiocarcinomas are highly aggressive malignancies. They are usually at an advanced stage at initial presentation. Surgical resection with negative margins is the standard of management. It provides the only chance of cure. Liver transplantation has increased the number of 'curative' procedures for cases previously considered to be unresectable. Meticulous and thorough preoperative planning is required to prevent fatal post-operative complications. Extended resection procedures, including hepatic trisectionectomy for Bismuth type IV tumors, hepatopancreaticoduodenectomy for tumors with extensive longitudinal spread, and combined vascular resection with reconstruction for tumors involving hepatic vascular structures, are challenging procedures with surgical indications expanded. Liver transplantation after the standardization of a neoadjuvant protocol described by the Mayo Clinic has increased the number of patients who can undergo operation.

Eur J Med Res 2023; 28:234. [PMID: 37443132 DOI: 10.1186/s40001-023-01209-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2022] [Accepted: 07/04/2023] [Indexed: 07/15/2023] Open
Abstract
BACKGROUND The main surgical procedure for Bismuth‒Corlette III-IV hilar cholangiocarcinoma (HCCA) is hemihepatectomy/extended hemihepatectomy. However, many patients have no opportunity for surgery due to having an insufficient remnant liver volume. Preservation of more liver volume on the premise of ensuring R0 resection is the goal. Mesohepatectomy with caudate lobectomy may be a new method to meet these requirements. METHODS The clinical data of 41 patients with Bismuth‒Corlette III-IV HCCA, including 18 patients who underwent mesohepatectomy with caudate lobectomy (the mesohepatectomy group) and 23 patients who underwent hemihepatectomy or extended hemihepatectomy (the hemihepatectomy group), were analyzed retrospectively. The perioperative indicators and prognostic survival time between the two groups were analyzed. RESULTS The mesohepatectomy group was compared with the hemihepatectomy group, and the operation time was 7.95 ± 1.2 vs. 7.15 ± 1.5 h (P > 0.05); the intraoperative blood loss was 600.0 ± 153.4 vs. 846.1 ± 366.8 mL (P < 0.05); the postoperative hospital stay was 9.9 ± 2.2 vs. 13.8 ± 3.0 days (P < 0.05); and the R0 resection rate was 100% vs. 87.0% (P > 0.05). The postoperative complications of the two groups included bile leakage (22.2% vs. 21.7%), pleural effusion (11.1% vs. 8.7%), and fever (16.7% vs. 8.7%), with no significant differences in the incidences (P > 0.05). The 1-, 3-, and 5-year survival rates of the two groups were 87.5%, 55.7%, 27.8% and 83.5%, 56.1%, 24.5%, respectively, with no significant differences (P > 0.05). CONCLUSIONS Mesohepatectomy with caudate lobectomy can preserve more functional liver volume while ensuring the bile duct margin. It can be applied as the surgical treatment of Bismuth‒Corlette III-IV HCCA.

Abstract
BACKGROUND To evaluate the clinical efficacy of percutaneous biliary drainage (PBD) combined with 125I seed strand brachytherapy (ISSB) for the treatment of hilar cholangiocarcinoma (HCCA). METHODS The clinical data of 64 patients with HCCA (median age 62.5, male 29, female 35) treated in our department from April 2017 to April 2021 were retrospectively analyzed. Thirty-four patients in the experimental group (EG) were treated with PBD combined with ISSB, while 30 patients in the control group (CG) were treated with PBD alone. The primary study endpoints were technical success, clinical success and the 2-month local tumor control (LTC) rate. Secondary endpoints were early/late complications, median progression-free survival (mPFS) and overall survival (mOS). RESULTS The technical and clinical success in the EG and CG showed no significant differences (100 vs. 100%, 94.1 vs. 93.3%, P > 0.05). Both early and late complications showed no significant differences between the two groups (P > 0.05). The 2-month LTC rates were significantly better in the EG versus the CG (94.1% vs. 26.7%, 157.7 ± 115.3 vs. 478.1 ± 235.3 U/ml), respectively (P < 0.05). The mPFS and mOS were 4.3 (95% CI 3.9-4.7) months and 2.8 (95% CI 2.5-3.1) months and 13.5 (95% CI 10.7-16.3) months and 8.8 (95% CI 7.8-9.8) months, respectively, with significant differences (P < 0.05). CONCLUSION PBD combined with ISSB is a safe and effective treatment for HCCA that can inhibit local tumors and prolong PFS and OS.

Abstract
Background Carbohydrate antigen 242 has been clinically used as a diagnostic biomarker for pancreatic cancer. However, the prognostic role of CA242 in hilar cholangiocarcinoma (HCCA) has not been identified. Also, it remains unclear to what extents the vascular invasion and lymph node metastasis mediate the effect of serum CA242 on prognosis. Objective This study aimed to investigate whether vascular invasion and lymph node metastasis mediate the relationship between CA242 levels and clinical prognosis in HCCA patients after radical resection. Methods Data of 234 HCCA patients who accepted radical resection from March 2008 to December 2014 were analyzed. Vascular invasion and lymph node metastasis were assessed by postoperative pathological examinations. Mediation analysis was performed to study the potential causal relationship between CA242 and overall survival (OS) and relapse-free survival (RFS). Survival analysis was performed using the Kaplan-Meier method. Results Among 234 HCCA patients, 104 patients (44.4%) with normal CA242 levels (≤ 20 IU/ml) had significantly better OS (p=0.004) and RFS (p=0.001) than those 130 patients (55.6%) with elevated CA242 levels (>20 IU/ml). The logistic analysis showed that elevated CA242 was an independent risk factor for vascular invasion (p=0.006) and lymph nodes metastasis (p=0.040). The causal mediation analysis indicated that the vascular invasion (p=0.012 for OS; p=0.036 for RFS) and lymph nodes metastasis (p=0.024 for OS; p=0.014 for RFS) played significant roles in mediating the effect of serum CA242 on OS and RFS. Conclusion Serum elevated CA242 could be a novel marker for prognosis prediction in HCCA patients. Vascular invasion and lymph node metastasis mediated the relationship between CA242 and clinical prognosis.

Abstract
OBJECTIVE Hilar cholangiocarcinoma (HCCA) is a malignancy related to chronic biliary tract inflammation. Tumor immune escape is a necessary process of tumorigenesis. Forkhead box M1 (FoxM1) could affect the progression of various carcinomas. This study attempted to elaborate on the mechanism of FoxM1 in HCCA immune escape. METHODS HCCA cell lines were collected to measure the expression of FoxM1 and FoxP3. CD8+ T cells were extracted to establish the co-culture system with HCCA cells and Treg cells. pcDNA3.1-FoxM1 or si-FoxP3 was transfected into HCCA cells in the co-culture system. HCCA cell viability, mobility, and invasiveness as well as levels of transforming growth factor (TGF)-β and interleukin (IL)-6 were evaluated. The binding relation between FoxM1 and FoxP3 promoter was verified. HCCA cells with pcDNA3.1-FoxM1 were subcutaneously injected into mice to establish the xenograft mouse models. RESULTS FoxM1 and FoxP3 were overexpressed in HCCA cells. The co-culture of CD8+ T and HCCA cells inhibited HCCA cell activity and Treg cells limited CD8+ T killing. FoxM1 overexpression strengthened the inhibiting role of Treg cells in CD8+ T killing, upregulated TGF-β and IL-6 levels, and encouraged HCCA immune escape. FoxM1 bound to the FoxP3 promoter region to promote FoxP3 transcription. Silencing of FoxP3 neutralized the promoting role of FoxM1 overexpression in Treg cell immunosuppression and HCCA cell immune escape. FoxM1 aggravated tumor development, upregulated FoxP3 expression, increased Treg cells, and reduced CD8+ T cells. CONCLUSION FoxM1 bound to the FoxP3 promoter region to promote FoxP3 transcription and recruited FoxP3+ Treg cells, thereby inducing HCCA immune escape.

Abstract
OBJECTIVE To investigate the application value of combined intravenous contrast-enhanced ultrasound (IV-CEUS) with intrabiliary contrast-enhanced ultrasound (IB-CEUS) in the preoperative evaluation of hilar cholangiocarcinoma (HCCA) resectability. METHODS Clinical data from 82 patients with HCCA confirmed by surgery and pathology were retrospectively analyzed. Preoperative IV-CEUS + IB-CEUS and magnetic resonance cholangiopancreatography (MRCP) were performed and the results were compared with surgical and pathological findings. RESULTS The accuracy of the Bismuth-Corlette classification confirmed by IV-CEUS + IB-CEUS and MRCP was 95.12% (78/82) and 87.8% (72/82), respectively. The diagnostic precision of IV-CEUS + IB-CEUS was better than MRCP (p = 0.001). The sensitivity, specificity, and precision of CEUS for diagnosing lymph node metastases (72.7%, 93.3%, and 87.8%), intrahepatic metastases (78.6%, 98.5%, and 93.9%), invasion of the hepatic artery (92.9%, 98.5%, and 97.6%) and invasion of the portal vein (93.8%, 98.5%, and 97.6%) of HCCA were, respectively. The consistency between the preoperative evaluation of resectability confirmed by IV-CEUS +IB-CEUS and MRCP was 85.4% (70/82) and 78.0% (64/82), respectively. In addition, the evaluations did not have statistically significant differences (p > 0.05). There were no significant differences between the two evaluations (p = 0.266). CONCLUSION IV-CEUS combined with IB-CEUS has significant value in classifying HCCA and evaluating the resectability of lymph node metastases, liver metastases, and vessel invasion.

Abstract
BACKGROUND Bismuth-Corlette type IV Klatskin tumors have conventionally been considered unresectable. This retrospective study aimed to demonstrate the survival improvement of patients with type IV Klatskin tumors when resected and suggest possible radiological features for R0 resectability. METHODS Data on type IV Klatskin tumors diagnosed between 2008 and 2019 were reviewed retrospectively. Patients with distant metastasis, concomitant other cancers at the initial state, extensive vascular invasions, poor liver function, and poor general condition were excluded. The survival outcomes of patients and radiologic parameters of bile duct tumors were compared between the curative resection (R0, 1 resection) and non-resection groups. RESULTS The demographic findings of patients with curative resection (n = 48) and non-resection (n = 111) were comparable. Both were potentially resectable in the initial state. The postoperative morbidity was 22.9% and the 90-day mortality 4.2%. There was a significant difference in the median survival among the curative-intended resection, palliative treatment, and supportive care groups (35, 16, and 12 months, respectively; P < 0.001). DISCUSSION In patients with type IV Klatskin tumor without extensive tumor invasion into adjacent tissues, including major vessels, surgical resection can be considered for better survival.

Abstract
The study objective was to detect the expression of farnesoid X receptor (FXR) in a rat model of hilar cholangiocarcinoma to provide a new therapeutic target for gene therapy in hilar cholangiocarcinoma. Sixty male Wistar rats (weighing 190 ± 8 g) were randomly divided into three groups (experimental group, control group and sham operation group, 20 rats in each group). The three groups were fed a standard diet. The QBC939 cell suspension of cholangiocarcinoma was injected into the hilar bile duct in the experimental group with a microsyringe. The control group was injected with normal saline, and the sham operation group was not injected with any drugs. A modified tail suspension test (TST) was used to evaluate the mental state and physical activity of rats every day. At 5 weeks, one rat in the experimental group was euthanized, and the changes in the hilar bile duct were recorded. The procedure was repeated at one and half months. After one and half months, hilar cholangiocarcinoma only occurred in the experimental group. Pathological examination confirmed the formation of tumours, and hilar bile duct tissues were taken from the three groups. FXR expression in the hilar bile duct was detected by real-time polymerase chain reaction (RT-PCR) and immunohistochemistry. After two weeks, the rats in the experimental group ate less, and their weight was significantly reduced. One and half months later, hilar cholangiocarcinoma was detected in 16 rats in the experimental group. The levels of alanine aminotransferase and aspartate transaminase in the experimental group were higher than those in the other two groups. The ratio of FXR/GAPDH mRNA was significantly different among the hilar cholangiocarcinoma, control and sham operation groups. Under the light microscope, FXR protein reacted with anti-FXR antibody and showed granular expression. Every pathological section included 4800 cells. A total of 1856 positive cells were in the experimental group, 3279 positive cells were in the control group, and 3371 positive cells were in the sham operation group. FXR expression in the hilar cholangiocarcinoma of rats was significantly lower than that in normal hilar bile duct tissues, suggesting that drugs targeting FXR may be a new strategy for the treatment of hilar cholangiocarcinoma.

Abstract
Perihilar cholangiocarcinoma is a rare hepatobiliary malignancy that requires thoughtful, multidisciplinary evaluation in the preoperative setting to ensure optimal patient outcomes. Comprehensive preoperative imaging, including multiphase CT angiography and some form of cholangiographic assessment, is key to assessing resectability. While many staging systems exist, the Blumgart staging system provides the most useful combination of resectability assessment and prognostic information for use in the preoperative setting. Once resectability is confirmed, volumetric analysis should be performed. Upfront resection without biliary drainage or portal venous embolization may be considered in patients without cholangitis and an estimated functional liver remnant (FLR) > 40%. In patients with FLR < 40%, judicious use of biliary drainage is advised, with the goal of selective biliary drainage of the functional liver remnant. Percutaneous biliary drainage may avoid inadvertent contamination of the contralateral biliary tree and associated infectious complications, though the relative effectiveness of percutaneous and endoscopic techniques is an ongoing area of study and debate. Patients with low FLR also require intervention to induce hypertrophy, most commonly portal venous embolization, in an effort to reduce the rate of postoperative liver failure. Even with extensive preoperative workup, many patients will be found to have metastatic disease at exploration and diagnostic laparoscopy may reduce the rate of non-therapeutic laparotomy. Management of perihilar cholangiocarcinoma continues to evolve, with ongoing efforts to improve preoperative liver hypertrophy and to further define the role of transplantation in disease management.

Predictive model for the intraoperative unresectability of hilar cholangiocarcinoma: Reducing futile surgical exploration. PLoS One 2022; 17:e0258522. [PMID: 35417458 PMCID: PMC9007352 DOI: 10.1371/journal.pone.0258522] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Accepted: 09/29/2021] [Indexed: 12/25/2022] Open
Abstract
Introduction Surgical exploration is widely performed in hilar cholangiocarcinoma (HCCA), but the intraoperative resectability rate is only 60%-80%. Exploration substantially increases pain and mental stress, and the costs and length of hospital stay are considerably increased. Identifying preoperative risk factors associated with unresectability could decrease unnecessary exploration. Materials and methods In total, 440 HCCA patients from multiple centers were enrolled. Those receiving surgical exploration were divided into the resected and unresected groups. Morphological variables including Bismuth classification, lymph node metastasis and vessel invasion were obtained from radiological exams. Logistic regression for the training cohort was used to identify risk factors for unresectability, and a nomogram was constructed to calculate the unresectability rate. A calibration curve assessed the power of the nomogram. Results Among 311 patients receiving surgical exploration, 45 (14.7%) were unresectable by intraoperative judgment. Compared with the resected group, unresected patients had similar costs (p = 0.359) and lengths of hospital stay (p = 0.439). Multivariable logistic regression of the training cohort (235 patients) revealed that CA125, Bismuth-Corlette type IV, lymph node metastasis and hepatic artery invasion were risk factors for unresectability. Liver atrophy (p = 0.374) and portal vein invasion (p = 0.114) were not risk factors. The nomogram was constructed based on the risk factors. The concordance index (C-index) values of the calibration curve for predicting the unresectability rate of the training and validation (76 patients) cohorts were 0.900 (95% CI, 0.835–0.966) and 0.829 (95% CI, 0.546–0.902), respectively. Conclusion Analysis of preoperative factors could reveal intraoperative unresectability and reduce futile surgical explorations, ultimately benefiting HCCA patients.

Abstract
BACKGROUND Traditionally, curative resection was considered the cornerstone of treatment for perihilar cholangiocarcinoma. More recently, liver transplantation (LT) offered an alternative for patients with unresectable disease. The purpose of this study was to assess our experience with perihilar cholangiocarcinoma and LT. METHODS A perihilar cholangiocarcinoma protocol was commenced in 2006 whereby diagnosed patients were enrolled onto an institutional registry for LT consideration. Data on patient progression and oncologic outcomes were assessed. RESULTS Fifty-eight patients were initially enrolled onto the protocol and 38 proceeded to LT following neoadjuvant chemoradiation (mean age 55.6 ± 11.4 years). Mean time to LT was 3.7 ± 2 months and, among those transplanted, 14 (37%) had underlying primary sclerosing cholangitis (PSC). Thirteen (34%) patients developed malignant recurrence and there were no differences in disease recurrence between PSC (n = 3) and non-PSC (n = 10) patients (p = 0.32). Overall patient survival was 91%, 58% and 52% at 1-, 3- and 5-years corresponding with 81%, 52% and 46% graft survival, respectively. CONCLUSION Rigorous patient selection and chemoradiation treatment algorithms can be highly effective in treating perihilar cholangiocarcinoma. For appropriately selected candidates, LT can provide a 52% 5-year survival for patients who would otherwise have no surgical treatment option.

Abstract
BACKGROUND The surgical approach to treat Bismuth type I and II hilar cholangiocarcinoma (HCCA) has been a topic of debate. We sought to characterize whether bile duct resection (BDR) with or without concomitant hepatic resection (HR) was associated with R0 margin status, as well as define the impact of HR+BDR versus BDR alone on long-term survival. METHODS Patients who underwent curative-intent HR+BDR for HCCA between 2000 and 2014 were identified from a multi-institutional database. Perioperative and long-term outcomes were compared among patients who underwent BDR only, BDR+left hepatic resection (LHR), and BDR+right hepatic resection (RHR) for Bismuth type I and II HCCA. RESULTS Among 257 patients with HCCA, 61 (23.7%) patients had a Bismuth type I (n=25, 41.0%) or II (n=36, 59.0%) lesion. The incidence of R0 resection after BDR only was the same as among patients after LHR and RHR (BDR 70.0% vs. BDR+LHR 71.4% vs. BDR+RHR 76.5%, p=0.891). In contrast, severe complications were more likely after LHR and RHR than BDR only (BDR 21.4% vs. BDR+LHR 60.0% and BDR+RHR 50.0%, p=0.041). Overall (median: BDR 20.9 vs. BDR+LHR 23.2 and BDR+RHR 25.0 months, p=0.213) and recurrence-free (median: BDR 13.4 vs. BDR+LHR 15.3 and BDR+RHR 25.0, p= 0.109) survival were comparable. On multivariable analysis, while CA19-9>37.0U/ml (Ref. CA19-9≤37.0U/ml, HR 3.2, 95% CI 1.1-9.4, p=0.035) and AJCC T3-T4 disease (Ref. T1-T2, HR 4.6, 95% CI 1.5-13.7, p=0.007) were associated with long-term survival, surgical approach was not (BDR+LHR: HR 1.0, 95% CI 0.5-2.2, p=0.937; BDR+RHR: HR 0.6, 95% CI 0.3-1.3, p=0.197). CONCLUSION R0 resection, overall survival, and recurrence-free survival were comparable among well-selected patients who had BDR versus BDR+HR for Bismuth type I and II HCCA.

Abstract
Simple Summary Perihilar cholangiocarcinoma (pCCA) is a relatively rare and aggressive hepatobiliary tumor with a general poor prognosis. Surgical therapy remains the only curative treatment option with the best prospects for long-term survival. However, tumor recurrence is frequent, and is associated with a poor prognosis. The identification of risk factors as well as appropriate selection of surgical candidates is essential to accurately predict prognosis and to maximize survival while decreasing tumor recurrence rates. Previous studies have already established a link between an increased BMI and the occurrence of various tumors. At present, data on BMI-associated long-term outcome following curative liver resection in pCCA patients are warranted. This study aims to investigate the impact of increased BMI on patient’s outcome, especially on tumor recurrence, following liver resection in patients with pCCA as well as to evaluate prognostic and risk factors for accurate prediction of outcome in this selective group of patients. Abstract Background: The association of body mass index (BMI) and long-term prognosis and outcome of patients with perihilar cholangiocarcinoma (pCCA) has not been well defined. The aim of this study was to evaluate clinicopathologic and oncologic outcomes with pCCA undergoing resection, according to their BMI. Methods: Patients undergoing liver resection in curative intention for pCCA at a tertiary German hepatobiliary (HPB) center were identified from a prospective database. Patients were classified as normal weight (BMI 18.5–24.9 kg/m2), overweight (BMI 25.0–29.9 kg/m2) and obese (>30 kg/m2) according to their BMI. Impact of clinical and histo-pathological characteristics on recurrence-free survival (RFS) were assessed using Cox proportional hazard regression analysis among patients of all BMI groups. Results: Among a total of 95 patients undergoing liver resection in curative intention for pCCA in the analytic cohort, 48 patients (50.5%) had normal weight, 33 (34.7%) were overweight and 14 patients (14.7%) were obese. After a median follow-up of 4.3 ± 2.9 years, recurrence was observed in totally 53 patients (56%). The cumulative recurrence probability was higher in obese and overweight patients than normal weight patients (5-year recurrence rate: obese: 82% versus overweight: 81% versus normal weight: 58% at 5 years; p = 0.02). Totally, 1-, 3-, 5- and 10-year recurrence-free survival rates were 68.5%, 44.6%, 28.9% and 13%, respectively. On multivariable analysis, increased BMI (HR 1.08, 95% CI: 1.01–1.16; p = 0.021), poor/moderate tumor differentiation (HR 2.49, 95% CI: 1.2–5.2; p = 0.014), positive lymph node status (HR 2.01, 95% CI: 1.11–3.65; p = 0.021), positive resection margins (HR 1.89, 95% CI:1.02–3.4; p = 0.019) and positive perineural invasion (HR 2.92, 95% CI: 1.02–8.3; p = 0.045) were independent prognostic risk factors for inferior RFS. Conclusion: Our study shows that a high BMI is significantly associated with an increased risk of recurrence after liver resection in curative intention for pCCA. This factor should be considered in future studies to better predict patient’s individual prognosis and outcome based on their BMI.

Abstract
OPINION STATEMENT Biliary malignancies, although rare, can be some of the most challenging to manage surgically. Intrahepatic cholangiocarcinomas are resectable if there is no evidence of metastatic disease. These tumors are managed with anatomic resection and portal lymphadenectomy when centrally located or multiple in a single lobe. Non-anatomic resection can be performed for solitary peripheral tumors with minimally invasive techniques. It is not our practice to routinely employ neoadjuvant chemotherapy prior to resection of these tumors. Hepatic arterial infusion chemotherapy is utilized at our institution in highly selected patients in the context of an ongoing clinical trial for unresectable tumors. Hilar cholangiocarcinomas, when resectable (i.e., ipsilateral arterial involvement or lack of vascular involvement), are managed with right or left (extended) hepatectomy, caudate resection, and portal lymphadenectomy. Distal cholangiocarcinomas are managed with pancreaticoduodenectomy. Neoadjuvant chemotherapy is not routinely used in our treatment algorithm of extrahepatic cholangiocarcinomas. Nodal involvement and positive margin (R1) resection necessitates adjuvant chemotherapy. Finally, gallbladder carcinoma is managed with radical cholecystectomy, anatomic segment IVb/V resection, and portal lymphadenectomy. Adjuvant chemotherapy is employed routinely amongst patients with T2 or higher tumors and those with positive lymph nodes.

Abstract
Hilar cholangiocarcinoma (HC) is a rare and highly aggressive biliary tract neoplasm. As such, the data driving the management of this disease generally are not based on prospective clinical trial data but rather consist of retrospective experiences and limited level 1 data. Surgical resection offers the best chance of a long-term survival, but local and distant recurrences are common. This report presents landmark articles that form the basis of preoperative, operative, and adjuvant strategies for HC.

Abstract
Develop a rat model of hilar cholangiocarcinoma for detecting bile salt export pump (Bsep) expression in hilar cholangiocarcinoma tissues, in order to provide a new therapeutic target for the gene therapy of hilar cholangiocarcinoma. Sixty male Wistar rats (body weight, 190 ± 8 g) were randomly divided into three groups (the experimental group, the control group and the sham operation group, n = 20 each) as follows: The three groups were fed a standard diet, the experimental group was injected by cholangiocarcinoma QBC939 cell suspension along the hilar bile duct into the bile duct bifurcation with microsyringe, the control group was injected by normal saline, the sham operation group did not inject anything. Every day assess the rats’ mental state, diet, and motion by using Basso–Beattie–Bresnahan and combined behavioral score. At 4 weeks, one rat of the experimental group was sacrificed after it was administered anesthesia, and we recorded changes in hilar bile duct size, texture, and form. This procedure was repeated at 6 weeks. After 6 weeks, hilar cholangiocarcinoma developed only in the experimental group, thereby establishing an experimental model for studying QBC939-induced hilar cholangiocarcinoma. Tumor formation was confirmed by pathological examination, and hilar bile duct tissues were harvested from both the groups. A real-time polymerase chain reaction assay and an immunohistochemical assay were used to analyze the expression of Bsep in hilar bile duct tissues of each group. From the second week, the rats in experimental group began to eat less, and their body mass decreased compared with control group and sham operation group. After 6 weeks, we detected hilar cholangiocarcinoma in the hilar bile duct tissues of 18 rats (90%) in the experimental group. In the experimental group with hilar cholangiocarcinoma, we found that the levels of total cholesterol, total bilirubin, and direct bilirubin were higher compared with those in the control group and sham operation group. Simultaneously, muddy stones emerged from the bile ducts of rats in the experimental group. The Bsep/Gapdh mRNA ratio in hilar cholangiocarcinoma, control group and sham operation group differed markedly. Light microscopy revealed a granular pattern of Bsep protein expression which reacted with the anti-Bsep antibody. Each section was randomly divided into six regions, with 80 cells were observed in every region. Sections with > 10% positive cells were designated positive, Sections with < 10% positive cells were designated negative. Each group included 4800 cells. In the experimental group, 1200 cells (25%) were positive, in the control group, 3648 cells (76%) were positive and in the sham operation group 3598 cells (75%) were positive, and this difference was statistically significant. Bsep expression significantly decreased in hilar cholangiocarcinoma of rats than those in control group and sham operation group, suggesting that drugs targeting Bsep are a new strategy for hilar cholangiocarcinoma.

Abstract
Objective This study aimed to investigate the use of three-dimensional visualization for preoperative evaluation of portal vein invasion in hilar cholangiocarcinoma (HCCA). Methods This recombination study for preoperative computerized tomography images was completed in 42 patients undergoing radical resection of HCCA combined with hepatectomy. Portal vein invasion with postoperative pathology was used as a gold standard to decide if the diagnosis was correct or not. We compared the sensitivity, specificity, positive predictive value, negative predictive value, and total correctness of radiologists and a three-dimensional (3D) visualization model for the assessment of tumor-caused portal vein invasion. Results The findings for the estimation of portal vein invasion by radiologists based on CT images were as follows: sensitivity = 90.9%; specificity = 83.8%; positive predictive value = 66.7%; negative predictive value = 96.3%; and overall accuracy = 85.7%. The findings for estimation by the 3D visualization model were as follows: sensitivity = 90.9%; specificity = 96.8%; positive predictive value = 90.9%; negative predictive value = 96.8%; and overall accuracy = 90.5%. Conclusion The positive predictive value of 3D visualization technology in the diagnosis of portal vein invasion is notably superior to that of subjective assessment by radiologists. This technique can thus play a significant role in preventing unnecessary resectioning of non-invaded portal veins and hepatectomy.

Complete laparoscopic radical resection of hilar cholangiocarcinoma: technical aspects and long-term results from a single center. Wideochir Inne Tech Maloinwazyjne 2020; 16:62-75. [PMID: 33786118 PMCID: PMC7991938 DOI: 10.5114/wiitm.2020.97363] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Accepted: 06/14/2020] [Indexed: 01/04/2023] Open
Abstract
Introduction The landscape of surgical treatments for hepatobiliary disease was significantly changed after the advent of laparoscopy. Many kinds of complex laparoscopic procedures can be routinely performed at present, but radical resection of hilar cholangiocarcinoma (HC) by laparoscopy is still highly contentious. Aim To describe our primary experience with laparoscopic radical resection for HC and determine the safety and feasibility of this procedure. Material and methods Between December 2015 and November 2019, 32 patients planned to undergo curative-intent laparoscopic resection of HC in our department. The perioperative and long-term outcomes of these patients were retrospectively analyzed. Results Laparoscopic surgery with radical resection was ultimately performed in 24 (75.0%) patients; 3 (9.3%) patients were found to be unresectable at the preliminary exploration stage, and 5 (15.7%) patients converted from laparoscopy to laparotomy. The operation time and blood loss were 476.95 ±133.89 min and 568.75 ±324.01 ml, respectively. A negative margin was achieved in 19 (79.1%) of the laparoscopy patients. Three (12.5%) patients were identified with microscopic positive margins, and 2 (8.4%) patients underwent macroscopic residual tumor resection (R2). The length of postoperative stay was 23.3 ±11.7 days. Severe morbidity occurred in 4 (16.6%) patients. The actuarial 3-year overall survival and disease-free survival for patients who underwent laparoscopic surgery were 49.1% and 47.0%, respectively. Conclusions Laparoscopic radical resection for HC is safe and feasible in experienced hands for highly selected patients but is still in its initial stages. When adequate oncologic resection is performed, the laparoscopic approach does not adversely influence the prognosis of the patient.

Independent Risk Factors of Early Recurrence After Curative Resection for Perihilar Cholangiocarcinoma: Adjuvant Chemotherapy May Be Beneficial in Early Recurrence Subgroup. Cancer Manag Res 2020; 12:13111-13123. [PMID: 33376403 PMCID: PMC7764637 DOI: 10.2147/cmar.s289094] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Accepted: 12/03/2020] [Indexed: 02/05/2023] Open
Abstract
PURPOSE In current clinical practice, early recurrence (ER) is not commonly discussed in perihilar cholangiocarcinoma (pCCA), and its risk factors for this disease have not been well clarified. We carried out this study to analyze the risk factors contributing to ER and explored the prognostic factors after curative resection for pCCA. PATIENTS AND METHODS A total of 335 consecutive pCCA patients were retrospectively analyzed. Risk factors contributing to ER were evaluated using univariate and multivariate logistic regression analyses. Prognostic factors of the ER group were determined by univariate and multivariate Cox regression models. The overall survival (OS) rate was calculated using the Kaplan-Meier method. The Log rank test was used for OS comparison. RESULTS Of the 335 cases, 258 patients (77.0%) developed tumor recurrence, 136 patients (40.6%) developed ER, and 122 patients (36.4%) developed late recurrence (LR) postoperatively. The median OS of the ER and LR groups was 15 months and 36 months, respectively (P<0.001). The multivariate analysis revealed that poor pathological differentiation (P=0.006; moderate vs well, odds ratio [OR]=2.162, 95% confidence interval [CI] 0.753-6.208, P=0.152; poor vs well, OR=4.839, 95% CI 1.544-15.170, P=0.007), perineural invasion (OR=4.797, 95% CI 1.586-14.510, P=0.005), and high levels of preoperative carbohydrate antigen 19-9 (CA19-9) (OR=2.205, 95% CI 1.208-4.026, P=0.010) were independent risk factors of developing ER after resection. Adjuvant chemotherapy (HR=0.383, 95% CI 0.154-0.953, P=0.039) remained as the independent protective factor of OS in patients with ER. CONCLUSION It is recommended that patients with poorly differentiated tumors, presence of perineural invasion, and high levels of preoperative CA19-9 receive closer follow-up and adjuvant chemotherapy following surgery.
