Abstract
Hepatobiliary cancer (HBC) includes hepatocellular carcinoma and biliary tract carcinoma (cholangiocarcinoma and gallbladder carcinoma), and its morbidity and mortality are significantly correlated with disease stage. Surgery is the cornerstone of curative therapy for early stage of HBC. However, a large proportion of patients with HBC are diagnosed with advanced stage and can only receive systemic treatment. According to the results of clinical trials, the first-line and second-line treatment programs are constantly updated with the improvement of therapeutic effectiveness. In order to improve the therapeutic effect, reduce the occurrence of drug resistance, and reduce the adverse reactions of patients, the treatment of HBC has gradually developed from single-agent therapy to combination. The traditional therapeutic philosophy proposed that patients with advanced HBC are only amenable to systematic therapies. With some encouraging clinical trial results, the treatment concept has been revolutionized, and patients with advanced HBC who receive novel systemic combination therapies with multi-modality treatment (including surgery, transplant, TACE, HAIC, RT) have significantly improved survival time. This review summarizes the treatment options and the latest clinical advances of HBC in each stage and discusses future direction, in order to inform the development of more effective treatments for HBC.

Abstract
Purpose: The present study aims to evaluate the effect of prognostic nutrition index (PNI) on the response and prognosis of patients with metastatic biliary tract cancer (BTC) patients treated with immunotherapy.Methods: The outcomes of 83 patients with metastatic BTC were evaluated retrospectively. Among them, 51 received immune checkpoint inhibitors (ICIs) treatment (ICIs cohort) and 32 patients received first-line chemotherapy (chemotherapy cohort). According to the optimal cutoff value of PNI, patients in ICIs cohort were divided into low PNI group (PNI < 44.30) and high PNI group (PNI≥ 44.30).Results: Patients received first-line immunotherapy-based combination antitumor therapy in ICIs cohort showed significant longer median PFS and OS contrast with first-line chemotherapy cohort. In ICIs cohort, median PFS and OS were significantly longer in the high PNI group. In addition, multivariate Cox regression analysis showed that high PNI was an independent risk factor for median PFS (hazard ratio (HR), 0.474, 95% CI, 0.246-0.910; P = 0.025) and median OS (HR, 0.229, 95% CI, 0.097-0.539; P = 0.001) in ICIs cohort, respectively. Conclusion: Our study provides preliminary evidence that immunotherapy for metastatic BTC is effective and safe. PNI was an independent prognostic indicator of median PFS and OS in patients with metastatic BTC receiving immunotherapy.

Abstract
Biliary tract cancers (BTC) arise from biliary epithelium and include cholangiocarcinomas or CCA (including intrahepatic (ICC) and extrahepatic (ECC)) and gallbladder cancers (GBC). They often have poor outcomes owing to limited treatment options, advanced presentations, frequent recurrence, and poor response to available systemic therapy. Mucin 5AC (MUC5AC) is rarely expressed in normal biliary epithelium, but can be upregulated in tissues of benign biliary disease, premalignant conditions (e.g., biliary intraepithelial neoplasia), and BTCs. This mucin's numerous glycoforms can be divided into less-glycosylated immature and heavily-glycosylated mature forms. Reported MUC5AC tissue expression in BTC varies widely, with some associations based on cancer location (e.g., perihilar vs. peripheral ICC). Study methods were variable regarding cancer subtypes, expression positivity thresholds, and MUC5AC glycoforms. MUC5AC can be detected in serum of BTC patients at high concentrations. The hesitancy in developing MUC5AC into a clinically useful biomarker in BTC management is due to variable evidence on the diagnostic and prognostic value. Concrete conclusions on tissue MUC5AC are difficult, but serum detection might be relevant for diagnosis and is associated with poor prognosis. Future studies are needed to further the understanding of the potential clinical value of MUC5AC in BTC, especially regarding predictive and therapeutic value.

Abstract
Biliary tract cancers (BTC) are often diagnosed at advanced stages and have a grave outcome due to limited systemic options. Gemcitabine and cisplatin combination (GC) has been the first-line standard for more than a decade. Second-line chemotherapy (CT) options are limited. Targeted therapy or TT (fibroblast growth factor 2 inhibitors or FGFR2, isocitrate dehydrogenase 1 or IDH-1, and neurotrophic tyrosine receptor kinase or NTRK gene fusions inhibitors) have had reasonable success, but <5% of total BTC patients are eligible for them. The use of immune checkpoint inhibitors (ICI) such as pembrolizumab is restricted to microsatellite instability high (MSI-H) patients in the first line. The success of the TOPAZ-1 trial (GC plus durvalumab) is promising, with numerous trials underway that might soon bring targeted therapy (pemigatinib and infrigatinib) and ICI combinations (with CT or TT in microsatellite stable cancers) in the first line. Newer targets and newer agents for established targets are being investigated, and this may change the BTC management landscape in the coming years from traditional CT to individualized therapy (TT) or ICI-centered combinations. The latter group may occupy major space in BTC management due to the paucity of targetable mutations and a greater toxicity profile.

The prognostic role of tumor-associated unilateral portal vein occlusion in perihilar cholangiocarcinoma. HPB (Oxford) 2021; 23:1565-1577.

Abstract
BACKGROUND While a certain degree of tumor infiltration of the portal vein is common in patients with perihilar cholangiocarcinoma (pCCA) scheduled for surgery, complete tumor-associated portal vein occlusion (PVO) is less frequently observed. Here, we analyzed the impact of PVO on perioperative and oncological outcomes in pCCA patients. METHODS Between 2010 and 2019, 127 patients with pCCA underwent surgery in curative intent at our department of which 17.3% (22/127) presented with PVO. Extensive group comparisons were conducted and the association of cancer-specific (CSS) and disease-free survival (DFS) with PVO and other clinico-pathological characteristics were assessed using Cox regression models. RESULTS Patients without PVO showed a median CSS of 65 months (3-year-CSS = 64%, 5-year-CSS = 53%) compared to 31 months (3-year-CSS = 43%, 5-year-CSS = 17%) in patients with PVO (p = 0.025 log rank). Patients with PVO did also display significant perioperative mortality (22.7%, 5/22) compared to patients without PVO (14.3%, 15/105, p = 0.323). Further, PVO (CSS: HR = 5.25, p = 0.001; DFS: HR = 5.53, p = 0.001) was identified as independent predictors of oncological outcome. CONCLUSIONS PVO has been identified as an important prognostic marker playing a role in inferior oncological outcome in patients with pCCA. As PVO is also associated with notable perioperative mortality, surgical therapy should be considered carefully in pCCA patients.

Abstract
Cholangiocarcinomas (CCAs) are the second-most common primary liver cancers. CCAs represent a group of highly heterogeneous tumors classified based on anatomical localization into intra- (iCCA) and extrahepatic CCA (eCCA). In contrast to eCCA, the incidence of iCCA is increasing worldwide. Curative treatment strategies for all CCAs involve oncological resection followed by adjuvant chemotherapy in early stages, whereas chemotherapy is administered at advanced stages of disease. Due to late diagnosis, high recurrence rates, and limited treatment options, the prognosis of patients remains poor. Comprehensive molecular characterization has further revealed considerable heterogeneity and distinct prognostic and therapeutic traits for iCCA and eCCA, indicating that specific treatment modalities are required for different subclasses. Several druggable alterations and oncogenic drivers such as fibroblast growth factor receptor 2 gene fusions and hotspot mutations in isocitrate dehydrogenase 1 and 2 mutations have been identified. Specific inhibitors have demonstrated striking antitumor activity in affected subgroups of patients in phase II and III clinical trials. Thus, improved understanding of the molecular complexity has paved the way for precision oncological approaches. Here, we outline current advances in targeted treatments and immunotherapeutic approaches. In addition, we delineate future perspectives for different molecular subclasses that will improve the clinical care of iCCA patients.

Abstract
INTRODUCTION Perihilar cholangiocarcinoma (pCCA) is a biliary tract cancer with a dismal prognosis, with surgery being the only chance of cure. A characteristic aggressive biological feature of pCCA is perineural growth which is defined by the invasion of cancer cells to nerves and nerve fibers. Recently, nerve fiber density (NFD) was linked to oncological outcomes in various malignancies; however, its prognostic role in pCCA remains to be elucidated. MATERIALS AND METHODS Data of 101 pCCA patients who underwent curative-intent surgery between 2010 and 2019 were included in this study. Extensive group comparisons between patients with high and low NFD were carried out, and the association of cancer-specific survival (CSS) and recurrence-free survival with NFD and other clinicopathological characteristics was assessed using univariate and multivariable cox regression models. RESULTS Patients with high NFD showed a median CSS of 90 months (95% CI: 48-132, 3-year CSS = 77%, 5-year CSS = 72%) compared to 33 months (95% CI: 19-47, 3-year CSS = 46%, 5-year CSS = 32%) in patients with low NFD (p = 0.006 log rank). Further, N1 category (HR = 2.84, p = 0.001) and high NFD (HR = 0.41, p = 0.024) were identified as independent predictors of CSS in multivariable analysis. Patients with high NFD and negative lymph nodes showed a median CSS of 90 months (3-year CSS = 88%, 5-year CSS = 80%), while patients with either positive lymph nodes or low NFD displayed a median CSS of 51 months (3-year CSS = 59%, 5-year CSS = 45%) and patients with both positive lymph nodes and low NFD a median CSS of 24 months (3-year CSS = 26%, 5-year CSS = 16%, p = 0.001 log rank). CONCLUSION NFD has been identified as an important novel prognostic biomarker in pCCA patients. NFD alone and in combination with nodal status in particular allows to stratify pCCA patients based on their risk for inferior oncological outcomes after curative-intent surgery.

Abstract
Abdominal infections including cholangitis represent a major problem in patients with perihilar cholangiocarcinoma (pCCA). Thus, we investigated bacterial colonization of the bile ducts and determined its impact on postoperative outcome focusing on abdominal infections. A cohort of 95 pCCA patients who underwent surgery between 2010 and 2019 with available intraoperative microbial bile cultures were analyzed regarding bile duct colonization and postoperative abdominal infection by group comparisons and logistic regressions. 84.2% (80/95) showed bacterial colonization of the bile ducts and 54.7% (52/95) developed postoperative abdominal infections. Enterococcus faecalis (38.8%, 31/80), Enterococcus faecium (32.5%, 26/80), Enterobacter cloacae (16.3%, 13/80) and Escherichia coli (11.3%, 9/80) were the most common bacteria colonizing the bile ducts and Enterococcus faecium (71.2%, 37/52), Enterococcus faecalis (30.8%, 16/52), Enterobacter cloacae (25.0%, 13/52) and Escherichia coli (19.2%, 10/52) the most common causes of postoperative abdominal infection. Further, reduced susceptibility to perioperative antibiotic prophylaxis (OR = 10.10, p = .007) was identified as independent predictor of postoperative abdominal infection. Bacterial colonization is common in pCCA patients and reduced susceptibility of the bacteria to the intraoperative antibiotic prophylaxis is an independent predictor of postoperative abdominal infections. Adapting antibiotic prophylaxis might therefore have the potential to improve surgical outcome pCCA patients.

Abstract
BACKGROUND Resection with trisectionectomy may necessitate liver molding for adequate future liver remnant (FLR), and subsequent complications can impact return to intended oncologic therapy (RIOT). This study evaluated whether a difference in RIOT exists with the use of molding and between liver molding techniques (associating liver partition and portal vein ligation for staged hepatectomy [ALPPS] and portal vein embolization [PVE]) with trisectionectomy. METHODS A retrospective review evaluated trisectionectomies for malignancy. Outcomes were compared with and without molding, and RIOT was determined. RESULTS Fifty-one patients underwent trisectionectomy: 11 ALPPS, 14 PVE, 26 without molding. 73% of ALPPS, 64% of PVE, and 58% without molding achieved RIOT (P = .971). There were no differences found in baseline characteristics, R0 rate, length of stay, readmission, complications, or mortality. Time to RIOT was significantly different (ALPPS: 3.3 months; PVE: 5.2 months; none: 2.4 months, P = .0203). There were no differences in recurrence or survival. CONCLUSIONS Liver molding should not cause apprehension as there are no differences in achieving RIOT. Although technique alters time to RIOT, this does not translate into improved outcomes, implicating disease biology, and regeneration stimulus.

This study aims to provide a deep insight into the incidence and clinical significance of postoperative anastomotic leakage (AL) and anastomotic stenosis (AS) of the hepaticojejunostomy (HJ) after curative-intent liver resection for perihilar cholangiocarcinoma (pCCA). Between 2011 and mid-2019, 114 patients with pCCA underwent surgery in curative intent at our institution and were analyzed regarding the postoperative incidence of AL and AS. Further, associations between AL and AS and clinical characteristics were assessed using multiple univariate logistic regression analyses. AL was diagnosed in 11.4% (13/114) of the patients resulting in postoperative mortality in the minority of patients (23.0%, 3/13). AS occurred in 11.0% (11/100) of the individuals eligible for follow-up with local tumor recurrence being the underlying pathology in 72.7% (8/11) of the cases. None of the investigated clinical factors including surgical difficulty of the HJ showed a meaningful association with AL or AS. AL and AS are frequent complications and can be treated by conservative, interventional or surgical therapy with a high success rate. Also, technical difficulty of the HJ appears not to be not associated with the occurrence of AL or AS. Moreover, AS is associated with tumor recurrence in the majority of cases.

Left- versus right-sided hepatectomy with hilar en-bloc resection in perihilar cholangiocarcinoma. HPB (Oxford) 2020; 22:437-444. [PMID: 31383591 DOI: 10.1016/j.hpb.2019.07.003] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2019] [Revised: 05/18/2019] [Accepted: 07/09/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND Major liver resections with portal vein resection (PVR) have emerged as the preferred treatment for patients with perihilar cholangiocarcinoma (pCCA). Whether the resection of the liver should be preferably performed as left- (LH) or right-sided hepatectomy (RH) with or without hilar en-bloc technique is still subject of ongoing debate. METHODS Between 2011 and 2016, 91 patients with pCCA underwent surgery in curative intent at our institution. Perioperative, pathological and survival data from all consecutive patients undergoing hilar en-bloc resection for pCCA were analyzed retrospectively. Patients undergoing hepatoduodenectomy (n = 8) or ALPPS (Associating liver partition and portal vein ligation for staged hepatectomy) (n = 2) were excluded from the analysis. RESULTS Tumor grading, microvascular invasion, lymphovascular invasion, N-category, T-category, R-status and UICC-tumor staging were similar in the RH (n = 45) and LH (n = 36) groups. Perioperative morbidity and mortality were higher after RH compared to LH (mortality: 15.6% (7/45) vs. 8.3% (3/36) p = 0.003). Three-year (62% vs. 51%) and the 5-year OS (30% vs. 46%) were comparable between LH and RH groups respectively (p = 0.519, log rank). CONCLUSIONS The present study supports the concept of surgically aggressive therapy in pCCA. LH and RH hilar en-bloc resection demonstrate a comparable long-term survival, suggesting that LH hilar en-bloc resections are feasible and safe in high-volume centers.

Abstract
PURPOSE Surgical resection constitutes the mainstay of curative treatment for intrahepatic cholangiocarcinoma (iCCA). Complete tumor clearance can only be achieved with extended liver resections and as such, associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) may facilitate surgical resectability. The present study aims to evaluate the technical feasibility and oncologic outcome of ALPPS in iCCA. METHODS A set of 14 patients who underwent ALPPS in a single center between 2011 and 2017 were statistically analyzed for perioperative and oncologic outcome. RESULTS Of all patients undergoing stage 1 of ALPPS, 12 (86%) patients were subsequently completed in stage 2 surgery. Patients who completed the ALPPS procedure showed a median overall survival (OS) of 4.2 years and a 3-year survival of 64%. Individuals without lymphatic metastases (n = 7) were all alive 1 year after surgery and if deceased, they died more than 4 years after surgery, while no patient with lymphatic metastases (n = 5) was alive 1 year after surgery. CONCLUSION This is the largest single-center experience of ALPPS in iCCA currently available in the literature showing excellent technical feasibility and encouraging overall survival in these patients.

Abstract
INTRODUCTION Cholangiocellular carcinoma (CCA) is an aggressive malignancy with a dismal prognosis. Among curative treatment options for CCA, radical surgical resection with extrahepatic bile duct resection, hepatectomy and en-bloc lymphadenectomy are considered the mainstay of curative therapy. Here, we aimed to identify prognostic markers of clinical outcome in CCA-patients who underwent surgical resection in curative intent. MATERIAL AND METHODS Between 2011 and 2016, 162 patients with CCA (perihilar CCA (pCCA): n = 91, intrahepatic CCA (iCCA): n = 71) underwent surgery in curative intent at our institution. Preoperative characteristics, perioperative data and oncological follow-up were obtained from a prospectively managed institutional database. The associations of overall- (OS) and disease-free-survival (DFS) with clinico-pathological characteristics were assessed using univariate and multivariable cox regression analyses. RESULTS The median OS and DFS were 38 and 36 months for pCCA and 25 and 13 months for iCCA, respectively. Lymphovascular invasion (LVI) and lymph node metastasis as well as surgical complications as assessed by the comprehensive complication index (CCI) and tumor grading were independently associated with OS for the pCCA (LVI; RR = 2.36, p = 0.028; CCI; RR = 1.04, p < 0.001) and iCCA cohorts (N-category; RR = 3.21, p = 0.040; tumor grading; RR = 3.75, p = 0.013; CCI, RR = 4.49, p = 0.010), respectively. No other clinical variable including R0-status and Bismuth classification was associated with OS. CONCLUSION Major liver resections for CCA are feasible and safe in experienced high-volume centers. Lymph node metastasis and LVI are associated with adverse clinical outcome, supporting the role of systematic lymphadenectomy. The assessment of LVI may be useful in identifying high-risk patients for adjuvant treatment strategies.

Abstract
BACKGROUND Cholangiocarcinomas (CCAs) are aggressive malignancies that display features of biliary differentiation. According to their anatomical location, CCAs are commonly classified as intrahepatic and extrahepatic tumors, the latter entity being further subdivided into perihilar CCAs, also termed as Klatskin tumors, and distal tumors. While a majority of CCAs occur sporadically, established risk factors such as liver fluke infestation or primary sclerosing cholangitis exist. SUMMARY Due to lack of efficient early screening markers, CCAs are frequently diagnosed at an advanced stage when curative surgical resection is not an option. Chemotherapy with gemcitabine and cisplatin is currently the standard palliative treatment that prolongs overall survival by 3.6 months as compared to monotherapy with gemcitabine. For CCA patients who progress under gemcitabine/cisplatin, the paucity of prospective, randomized trials is detrimental, and there is currently no recommended second-line regimen with respect to chemotherapy or loco-regional treatment modalities. Molecular profiling of CCAs supports the implementation of targeted approaches, and it is reasonable that personalized therapy will become a mainstay of CCA treatment. In addition, the advent of immunotherapy holds considerable promise, yet, similar to targeted treatment, needs to be prospectively evaluated in clinically and genetically thoroughly characterized patients. KEY POINTS (1) CCA is a genetically diverse and highly aggressive malignancy. (2) Gemcitabine in combination with cisplatin or oxaliplatin is the current first-line chemotherapy in non-resectable patients. (3) Loco-regional treatment modalities exist but need to be evaluated in prospective randomized trials in the context of systemic chemotherapy. (4) Targeted therapies in molecularly defined subgroups of patients and immunotherapies alone or in combinations will most likely improve survival in the future.

Abstract
Key substrates including glucose, amino acids, and fatty acids play core roles in nutrient metabolism. In this review, we describe phenomena observed when key substrates are applied to cells. We focused on three promising substrates: L-glucose derivatives, 5-aminolevulinic acid, and polyunsaturated fatty acid. Since they are assumed to give a specific reaction when they are transported into cells or metabolized in cells, they are expected to be applied in a clinical setting. We provide the latest knowledge regarding their behaviors and effects on cells.

Abstract
Intrahepatic cholangiocarcinoma (ICC) is a rare yet deadly malignancy with limited treatment options. Activation of the Notch signalling cascade has been implicated in cholangiocarcinogenesis. However, while several studies focused on the Notch receptors required for ICC development, little is known about the upstream inducers responsible for their activation. Here, we show that the Jagged 1 (Jag1) ligand is almost ubiquitously upregulated in human ICC samples when compared with corresponding non-tumorous counterparts. Furthermore, we found that while overexpression of Jag1 alone does not lead to liver tumour development, overexpression of Jag1 synergizes with activated AKT signalling to promote liver carcinogenesis in AKT/Jag1 mice. Histologically, tumours consisted exclusively of ICC, with hepatocellular tumours not occurring in AKT/Jag1 mice. Furthermore, tumours from AKT/Jag1 mice exhibited extensive desmoplastic reaction, an important feature of human ICC. At the molecular level, we found that both AKT/mTOR and Notch cascades are activated in AKT/Jag1 ICC tissues, and that the Notch signalling is necessary for ICC development in AKT/Jag1 mice. In human ICC cell lines, silencing of Jag1 via specific small interfering RNA reduces proliferation and increases apoptosis. Finally, combined inhibition of AKT and Notch pathways is highly detrimental for the in vitro growth of ICC cell lines. In summary, our study demonstrates that Jag1 is an important upstream inducer of the Notch signalling in human and mouse ICC. Targeting Jag1 might represent a novel therapeutic strategy for the treatment of this deadly disease.

Abstract
Primary sclerosing cholangitis (PSC) remains a rare but significant disease, which affects mainly young males in association with inflammatory bowel disease. There have been few advances in the understanding of the pathogenesis of the condition and no therapeutics with proven mortality benefit aside from liver transplantation. There remain areas of controversy in the management of PSC which include the differentiation from other cholangiopathies, in particular immunoglobulin G4 related sclerosing cholangitis, the management of dominant biliary strictures, and the role of ursodeoxycholic acid. In addition, the timing of liver transplantation in PSC remains difficult to predict with standard liver severity scores. In this review, we address these controversies and highlight the latest evidence base in the management of PSC.

Abstract
Extrahepatic bile duct cancer (cholangiocarcinoma) has a poor prognosis. Since surgical resection is the only way to prolong the patient’s life, it is of critical importance to correctly determine the extent of lesions. However, conventional pre-operative assessments have insufficient spatial resolution for determining the surgical margin. A fluorescent contrast agent might provide a more precise measure to identify anomalies in biliary surface, when combined with probe-based confocal laser endomicroscopy (pCLE). We have previously shown that 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)amino]-2-deoxy-l-glucose (2-NBDLG), a fluorescent derivative of l-glucose (fLG), is specifically taken up into spheroids consisting of cells showing heterogeneous nuclear-cytoplasm ratio, a feature of malignant cells in clinical settings. In addition, a combined use of 2-TRLG, a membrane-impermeable fLG, with 2-NBDLG visualized membrane integrity as well. We therefore explored in the present study the availability of the fLGs in vivo as a contrast agent for pCLE by using a hamster model of cholangiocarcinoma. Extrahepatic cholangiocarcinoma developed in mid common duct in ~20 % of the animals subjected to cholecystoduodenostomy with the ligation at the distal end of the common duct followed by injection of a carcinogen N-nitrosobis(2-oxopropyl)amine. After infusing bile duct with a solution containing 2-NBDLG and 2-TRLG, the lumen was surgically exposed and examined by pCLE. Fluorescence pattern characterized by bright spots and dark clumps was detected in the areas diagnosed with cholangiocarcinoma in later histopathology, whereas no such pattern was detected in control animals. These findings may form a basis for elucidating a potential availability of fLGs in imaging cholangiocarcinoma by pCLE.
