RESUMEN
BACKGROUND AND AIMS: Tea and coffee are widely consumed beverages worldwide. We evaluated their association with biliary tract cancer (BTC) incidence. APPROACH AND RESULTS: We pooled data from 15 studies in the Biliary Tract Cancers Pooling Project to evaluate associations between tea and coffee consumption and biliary tract cancer development. We categorized participants as nondrinkers (0 cup/day), moderate drinkers (>0 and <3 cups/day), and heavy drinkers (≥3 cups/day). We estimated multivariable HRs and 95% CIs using Cox models. During 29,911,744 person-years of follow-up, 851 gallbladder, 588 intrahepatic bile duct, 753 extrahepatic bile duct, and 458 ampulla of Vater cancer cases were diagnosed. Individuals who drank tea showed a statistically significantly lower incidence rate of gallbladder cancer (GBC) relative to tea nondrinkers (HR=0.77; 95% CI, 0.64-0.91), and intrahepatic bile duct cancer (IHBDC) had an inverse association (HR=0.81; 95% CI, 0.66-1.00). However, no associations were observed for extrahepatic bile duct cancer (EHBDC) or ampulla of Vater cancer (AVC). In contrast, coffee consumption was positively associated with GBC, with a higher incidence rate for individuals consuming more coffee (HR<3 cups/day =1.29; 95% CI, 1.01-1.66; HR≥3 cups/day =1.49; 95% CI, 1.11-1.99, Ptrend=0.01) relative to coffee nondrinkers. However, there was no association between coffee consumption and GBC when restricted to coffee drinkers. There was little evidence of associations between coffee consumption and other biliary tract cancers. CONCLUSIONS: Tea consumption was associated with a lower incidence of GBC and possibly IHBDC. Further research is warranted to replicate the observed positive association between coffee and GBC.

Thailand is among countries with the highest global incidence and mortality rates of hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA). While viral hepatitis and liver fluke infections have been associated with HCC and iCCA, respectively, other environmental risk factors, overall risk factor commonality and combinatorial roles, and effects on survival have not been systematically examined. We conducted a TIGER-LC consortium-based population study covering all high-incidence areas of both malignancies across Thailand: 837 HCC, 1474 iCCA, and 1112 controls (2011-2019) were comprehensively queried on lifelong environmental exposures, lifestyle, and medical history. Multivariate logistic regression and Cox proportional hazards analyses were used to evaluate risk factors and associated survival patterns. Our models identified shared risk factors between HCC and iCCA, such as viral hepatitis infection, liver fluke infection, and diabetes, including novel and shared associations of agricultural pesticide exposure (OR range of 1.50; 95% CI: 1.06-2.11 to 2.91; 95% CI: 1.82-4.63) along with vulnerable sources of drinking water. Most patients had multiple risk factors, magnifying their risk considerably. Patients with lower risk levels had better survival in both HCC (HR 0.78; 95% CI: 0.64-0.96) and iCCA (HR 0.84; 95% CI: 0.70-0.99). Risk factor co-exposures and their common associations with HCC and iCCA in Thailand emphasize the importance for future prevention and control measures, especially in its large agricultural sector. The observed mortality patterns suggest ways to stratify patients for anticipated survivorship and develop plans to support medical care of longer-term survivors, including behavioral changes to reduce exposures.

Cholangiocarcinoma (CCA) is the second most common hepatobiliary malignancy after hepatocellular carcinoma. Due to the poor treatment effect and high mortality rate of CCA, it is of great significance to explore new therapeutic targets. Ferroptosis is a type of cell death caused by iron-dependent cell oxidative injury, which is closely related to the occurrence and development of numerous diseases. Novel ideas for the prevention and treatment of related diseases have been provided by ferroptosis, which has become a focus of research in recent years. This review introduces the underlying mechanisms related to ferroptosis, as well as a research update for ferroptosis in the occurrence and development of CCA. The clinical value of ferroptosis-related regulatory mechanisms in CCA will be elucidated.

BACKGROUND: Recent studies supported the association between occupational exposure to asbestos and risk of cholangiocarcinoma (CC). Aim of the present study is to investigate this association using an update of mortality data from the Italian pooled asbestos cohort study and to test record linkage to Cancer Registries to distinguish between hepatocellular carcinoma (HCC) and intrahepatic/extrahepatic forms of CC. METHODS: The update of a large cohort study pooling 52 Italian industrial cohorts of workers formerly exposed to asbestos was carried out. Causes of death were coded according to ICD. Linkage was carried out for those subjects who died for liver or bile duct cancer with data on histological subtype provided by Cancer Registries. RESULTS: 47 cohorts took part in the study (57,227 subjects). We identified 639 causes of death for liver and bile duct cancer in the 44 cohorts covered by Cancer Registry. Of these 639, 240 cases were linked to Cancer Registry, namely 14 CC, 83 HCC, 117 cases with unspecified histology, 25 other carcinomas, and one case of cirrhosis (likely precancerous condition). Of the 14 CC, 12 occurred in 2010-2019, two in 2000-2009, and none before 2000. CONCLUSION: Further studies are needed to explore the association between occupational exposure to asbestos and CC. Record linkage was hampered due to incomplete coverage of the study areas and periods by Cancer Registries. The identification of CC among unspecific histology cases is fundamental to establish more effective and targeted liver cancer screening strategies.

BACKGROUND & AIMS: The PTEN-AKT pathway is frequently altered in extrahepatic cholangiocarcinoma (eCCA). We aimed to evaluate the role of PTEN in the pathogenesis of eCCA and identify novel therapeutic targets for this disease. METHODS: The Pten gene was genetically deleted using the Cre-loxp system in biliary epithelial cells. The pathologies were evaluated both macroscopically and histologically. The characteristics were further analyzed by immunohistochemistry, reverse-transcription PCR, cell culture, and RNA sequencing. Some features were compared to those in human eCCA samples. Further mechanistic studies utilized the conditional knockout of Trp53 and Aurora kinase A (Aurka) genes. We also tested the effectiveness of an Aurka inhibitor. RESULTS: We observed that genetic deletion of the Pten gene in the extrahepatic biliary epithelium and peri-ductal glands initiated sclerosing cholangitis-like lesions in mice, resulting in enlarged and distorted extrahepatic bile ducts in mice as early as 1 month after birth. Histologically, these lesions exhibited increased epithelial proliferation, inflammatory cell infiltration, and fibrosis. With aging, the lesions progressed from low-grade dysplasia to invasive carcinoma. Trp53 inactivation further accelerated disease progression, potentially by downregulating senescence. Further mechanistic studies showed that both human and mouse eCCA showed high expression of AURKA. Notably, the genetic deletion of Aurka completely eliminated Pten deficiency-induced extrahepatic bile duct lesions. Furthermore, pharmacological inhibition of Aurka alleviated disease progression. CONCLUSIONS: Pten deficiency in extrahepatic cholangiocytes and peribiliary glands led to a cholangitis-to-cholangiocarcinoma continuum that was dependent on Aurka. These findings offer new insights into preventive and therapeutic interventions for extrahepatic CCA. IMPACT AND IMPLICATIONS: The aberrant PTEN-PI3K-AKT signaling pathway is commonly observed in human extrahepatic cholangiocarcinoma (eCCA), a disease with a poor prognosis. In our study, we developed a mouse model mimicking cholangitis to eCCA progression by conditionally deleting the Pten gene via Pdx1-Cre in epithelial cells and peribiliary glands of the extrahepatic biliary duct. The conditional Pten deletion in these cells led to cholangitis, which gradually advanced to dysplasia, ultimately resulting in eCCA. The loss of Pten heightened Akt signaling, cell proliferation, inflammation, fibrosis, DNA damage, epigenetic signaling, epithelial-mesenchymal transition, cell dysplasia, and cellular senescence. Genetic deletion or pharmacological inhibition of Aurka successfully halted disease progression. This model will be valuable for testing novel therapies and unraveling the mechanisms of eCCA tumorigenesis.

BACKGROUND: Cholangiocarcinoma (CCA) is experiencing a global increase, particularly in Northeast Thailand, which has the highest global incidence rates. However, there is a paucity of studies on CCA screening, especially in high-risk populations. This study aimed to investigate the distribution and spatial patterns of CCA in Northeast Thailand over a ten-year screening period. METHODS: The study included CCA patients from the Cholangiocarcinoma Screening and Care Program (CASCAP) between 2013 and 2022, which encompasses 20 provinces and 282 districts in Northeast of Thailand. CCA data were based on pathological diagnosis to determine the distribution and spatial patterns. RESULTS: Of the 2,515 CCA patients, approximately two-thirds were males (63.98%), and the majority were aged over 55 years (72.72%), with a mean age of 61.12 ± 9.13 years. The highest percentage of CCA cases occurred in 2014 at 19.01% of all patients, followed by 2018 at 15.23%. The overall CCA incidence rate in Northeast Thailand over ten years was 32 per 100,000 population. Hotspot statistical analysis identified high-scoring geographic clusters in the upper and middle regions, showing a tendency to expand from hotspot areas into nearby areas. CONCLUSION: The distribution of CCA in Northeast Thailand has continued to rise over the past decade, particularly in the upper and middle regions. Targeted screening in high-risk areas and increased awareness of CCA risks are crucial to mitigate its impact.

Biliary tract malignant tumors account for about 3% of gastrointestinal malignancies. Based on anatomical location, biliary tract malignant tumors can be divided into gallbladder carcinoma, intrahepatic cholangiocarcinoma (ICC), hilar cholangiocarcinoma, and distal cholangiocarcinoma. Surgical treatment is the main treatment for early-stage biliary malignant tumors, the insidious nature of the disease often leads to late diagnoses, causing many patients missing the window for surgical intervention. Gemcitabine combined with cisplatin serves as a first-line treatment for patients with advanced or unresectable lesions, however, a definitive standard for second-line treatment has not yet been established. In recent years, many advances have occurred in the study of the molecular mechanisms contributing to the occurrence and development of biliary malignancies, providing a foundation for targeted treatments of the disease. This review summarizes the existing literature and explores potential second-line treatment options for advanced biliary malignancies based on our understanding of the molecular pathogenesis and tumor pathology.

BACKGROUND Wilson's disease is a rare autosomal recessive disorder characterized by excessive accumulation of copper in the liver, brain, and kidneys. Although it affects only approximately 1 in 30 000 individuals, it leads to progressive liver damage and neurological issue. Wilson's disease presents a wide spectrum of clinical manifestations related to hepatic disease, ranging from asymptomatic cases to acute liver failure. The occurrence of hepatobiliary malignancies, including intrahepatic cholangiocarcinoma, is relatively uncommon in Wilson's disease, even among patients with cirrhosis. Only 14 cases have been published so far, including the present report, and its etiology remains unclear. CASE REPORT We report the successful treatment of intrahepatic cholangiocarcinoma in a 39-year-old woman with Wilson's disease. Twenty-two years after being diagnosed with Wilson's disease, intrahepatic cholangiocarcinoma was diagnosed. She had an intrahepatic mass that was found to be a 4.3-cm ill-defined hypodense lesion in liver segment 3/4, with features suggesting infiltrative intrahepatic cholangiocarcinoma rather than hepatocellular carcinoma. Laboratory results showed slightly elevated liver enzymes and tumor markers. There was no evidence of metastasis on chest computed tomography or positron emission tomography, and the tumor was resectable, so surgery was the first-choice treatment option. Left hepatectomy was performed successfully, and the final pathology confirmed adenocarcinoma with clear resection margins. The patient received adjuvant chemotherapy with capecitabine. To date, the patient has been doing well without evidence of recurrence or metastasis. CONCLUSIONS Despite limited knowledge regarding hepatic malignancy in Wilson's disease, it is crucial to prioritize careful monitoring and develop suitable treatment strategies upon diagnosis to achieve favorable outcomes, considering the potential occurrence of intrahepatic cholangiocarcinoma in Wilson's disease.

Cholangiocarcinoma (CCA) is a prevalent cancer in Southeast Asia, with Opisthorchis viverrini (O.viverrini) infection being the primary risk factor. Most CCA cases in this region are diagnosed at advanced stages, leading to unfavorable prognoses. The development of stage-specific biomarkers for Opisthorchis viverrini-induced cholangiocarcinoma (Ov-CCA) holds crucial significance, as it facilitates early detection and timely administration of curative interventions, effectively mitigating the high morbidity and mortality rates associated with this disease in the Great Mekong region. Biomarkers are a promising approach for early detection, prognosis, and targeted treatment of CCA. Disease-specific biomarkers facilitate early detection and enable monitoring of therapy effectiveness, allowing for any necessary corrections. This review provides an overview of the potential O. viverrini-specific molecular biomarkers and important markers for diagnosing and monitoring Ov-CCA, discussing their prognostic, predictive, and diagnostic value. Despite the limited research in this domain, several potential biomarkers have been identified, encompassing both worm-induced and host-induced factors. This review offers a thorough examination of historical and contemporary progress in identifying biomarkers through multiomics techniques, along with their potential implications for early detection and treatment.

BACKGROUND: Discontinuation of the Codman 3000 pump in 2018 left no Food and Drug Administration (FDA)-approved hepatic artery infusion (HAI) device for unresectable colorectal liver metastases (uCLM) and intrahepatic cholangiocarcinoma (uIHC). Historically, HAI has been performed at academic medical centers in large metropolitan areas, which are often inaccessible to rural patients. Consequently, feasibility of dissemination of HAI to rural populations is unknown. PATIENTS AND METHODS: Under an FDA investigational device exemption, we opened the only HAI program in Kentucky and enrolled patients with uCLM and uIHC in a phase I clinical trial. The trial examined the safety of the hybrid Codman catheter/Medtronic SynchroMed II pump (hCMP) combination, defined as successful completion of one cycle of HAI chemotherapy. Rural feasibility was assessed by number of missed pump fills appointments. RESULTS: A total of 21 patients (n = 17 uCLM, n = 4 uIHC) underwent hCMP implantation before accrual was stopped early owing to FDA approval of the Intera 3000 pump. 20/21 (95%) patients met the primary safety endpoint. Serious adverse events (AEs) included a grade 5 coronavirus disease 2019 (COVID-19) infection (n = 1) and a grade 3 catheter erosion into the bowel (n = 1). Biliary sclerosis developed in two patients (9.5%). Median distance to infusion center was 47.6 miles (2-138 miles), and 62% were from Appalachia, yet there were no missed pump fill appointments. The 2-year overall survival was 82.4% (uCLM) and 50% (uIHC). CONCLUSIONS: The hCMP device had an acceptable safety profile. Despite the complexity of starting a new HAI program, early results showed feasibility for HAI delivery in a rural catchment area and comparable outcomes to larger urban-based HAI centers.

Cholangiocarcinomas (CCAs) constitute a heterogeneous group of highly malignant epithelial tumors arising from the biliary tree. This cluster of malignant tumors includes three distinct entities, the intrahepatic, perihilar, and distal CCAs, which are characterized by different epidemiological and molecular backgrounds, as well as prognosis and therapeutic approaches. The higher incidence of CCA over the last decades, the late diagnostic time that contributes to a high mortality and poor prognosis, as well as its chemoresistance, intensified the efforts of the scientific community for the development of novel diagnostic tools and therapeutic approaches. Extracellular vesicles (EVs) comprise highly heterogenic, multi-sized, membrane-enclosed nanostructures that are secreted by a large variety of cells via different routes of biogenesis. Their role in intercellular communication via their cargo that potentially contributes to disease development and progression, as well as their prospect as diagnostic biomarkers and therapeutic tools, has become the focus of interest of several current studies for several diseases, including CCA. The aim of this review is to give a rundown of the current knowledge regarding the emerging role of EVs in cholangiocarcinogenesis and their future perspectives as diagnostic and therapeutic tools.

BACKGROUND: It is estimated that 6% to 20% of all cholangiocarcinoma (CCA) diagnoses are explained by primary sclerosing cholangitis (PSC), but the underlying risk factors in the absence of PSC are unclear. We examined associations of different risk factors with intrahepatic cholangiocarcinoma (ICC) and extrahepatic cholangiocarcinoma (ECC) in the United States. METHODS: We conducted a case-control study of 121 patients with ECC and 308 patients with ICC treated at MD Anderson Cancer Center between May 2014 and March 2020, compared with 1,061 healthy controls. Multivariable logistic regression analysis was applied to estimate the adjusted OR (AOR) and 95% confidence interval (CI) for each risk factor. RESULTS: Being Asian, diabetes mellitus, family history of cancer, and gallbladder stones were associated with higher odds of developing ICC and ECC. Each 1-unit increase in body mass index in early adulthood (ages 20-40 years) was associated with a decrease in age at diagnosis of CCA (6.7 months, P < 0.001; 6.1 months for ICC, P = 0.001; 8.2 months for ECC, P = 0.007). A family history of cancer was significantly associated with the risk of ICC and ECC development; the AORs (95% CI) were 1.11 (1.06-1.48) and 1.32 (1.01-2.00) for ICC and ECC, respectively. CONCLUSIONS: In this study, early adulthood onset of obesity was significantly associated with CCA and may predict early diagnosis at younger age than normal weight individuals. IMPACT: The study highlights the association between obesity and CCA, independent of PSC. There is a need to consider the mechanistic pathways of obesity in the absence of fatty liver and cirrhosis.

PURPOSE: Most patients with intrahepatic cholangiocarcinoma (IHCC) develop recurrence after resection. Adjuvant capecitabine remains the standard of care for resected IHCC. A combination of gemcitabine, cisplatin, and nab-paclitaxel (GAP) was associated with a 45% response rate and 20% conversion rate among patients with unresectable biliary tract cancers. The aim of this study was to evaluate the feasibility of delivering GAP in the neoadjuvant setting for resectable, high-risk IHCC. METHODS: A multi-institutional, single-arm, phase II trial was conducted for patients with resectable, high-risk IHCC, defined as tumor size > 5 cm, multiple tumors, presence of radiographic major vascular invasion, or lymph node involvement. Patients received preoperative GAP (gemcitabine 800 mg/m2, cisplatin 25 mg/m2, and nab-paclitaxel 100 mg/m2 on days 1 and 8 of a 21-day cycle) for a total of 4 cycles prior to an attempt at curative-intent surgical resection. The primary endpoint was completion of both preoperative chemotherapy and surgical resection. Secondary endpoints were adverse events, radiologic response, recurrence-free survival (RFS), and overall survival (OS). RESULTS: Thirty evaluable patients were enrolled. Median age was 60.5 years. Median follow-up for all patients was 17 months. Ten patients (33%) experienced grade ≥ 3 treatment-related adverse events, the most common being neutropenia and diarrhea; 50% required ≥ 1 dose reduction. The disease control rate was 90% (progressive disease: 10%, partial response: 23%, stable disease: 67%). There was zero treatment-related mortality. Twenty-two patients (73%, 90% CI 57-86; p = 0.008) completed all chemotherapy and surgery. Two patients (9%) who successfully underwent resection had minor postoperative complications. Median length of hospital stay was 4 days. Median RFS was 7.1 months. Median OS for the entire cohort was 24 months and was not reached in patients who underwent surgical resection. CONCLUSION: Neoadjuvant treatment with gemcitabine, cisplatin, and nab-paclitaxel is feasible and safe prior to resection of intrahepatic cholangiocarcinoma and does not adversely impact perioperative outcomes.

BACKGROUND: The prognosis of patients with advanced biliary tract cancer (BTC) who have progressed on gemcitabine plus cisplatin is dismal. Trifluridine/tipiracil (FTD/TPI) and irinotecan have proven efficacy in different gastrointestinal malignancies. We therefore hypothesized that this combination might improve the therapeutic outcome in patients with BTC after failure of first line treatment. METHODS: TRITICC is an interventional, prospective, open-label, non-randomised, exploratory, multicentre, single-arm phase IIA clinical trial done in 6 sites with expertise in managing biliary tract cancer across Germany. A total of 28 adult patients (aged ≥ 18 years) with histologically verified locally advanced or metastatic biliary tract cancer (including cholangiocarcinoma and gallbladder or ampullary carcinoma) with documented radiological disease progression to first-line gemcitabine based chemotherapy will be included to receive a combination of FTD/TPI plus irinotecan according to previously published protocols. Study treatment will be continued until disease progression according to RECIST 1.1 criteria or occurrence of unacceptable toxicity. The effect of FTD/TPI plus irinotecan on progression-free survival will be analyzed as primary endpoint. Safety (according to NCI-CTCAE), response rates and overall survival are secondary endpoints. In addition, a comprehensive translational research program is part of the study and might provide findings about predictive markers with regard to response, survival periods and resistance to treatment. DISCUSSION: The aim of TRITICC is to evaluate the safety and efficacy of FTD/TPI plus irinotecan in patients with biliary tract cancer refractory to previous Gemcitabine based treatment.

INTRODUCTION: Guidelines for perioperative systemic therapy administration in patients undergoing pancreatoduodenectomy for pancreatic adenocarcinoma (PDAC) and distal cholangiocarcinoma (dCCA) are evolving. Decisions regarding adjuvant therapy are influenced by postoperative morbidity, which is common after pancreatoduodenectomy. We evaluated whether postoperative complications are associated with receipt of adjuvant therapy after pancreatoduodenectomy. METHODS: A retrospective analysis of patients undergoing pancreatoduodenectomy for PDAC or dCCA from 2015 to 2020 was conducted. Demographic, clinicopathologic, and postoperative variables were analyzed. RESULTS: Overall, 186 patients were included-145 with PDAC and 41 with dCCA. Postoperative complication rates were similar for both pathologies (61% and 66% for PDAC and dCCA, respectively). Major postoperative complications (MPCs), defined as Clavien-Dindo >3, occurred in 15% and 24% of PDAC and dCCA patients, respectively. Patients with MPCs received lower rates of adjuvant therapy administration, irrespective of primary tumor (PDAC: 21 vs. 72%, p = 0.008; dCCA: 20 vs. 58%, p = 0.065). Recurrence-free survival (RFS) was worse for patients with PDAC who experienced an MPC [8 months (interquartile range [IQR] 1-15) vs. 23 months (IQR 19-27), p < 0.001] or who did not receive any perioperative systemic therapy [11 months (IQR 7-15) vs. 23 months (IQR 18-29), p = 0.038]. In patients with dCCA, 1-year RFS was worse for patients who did not receive adjuvant therapy (55 vs. 77%, p = 0.038). CONCLUSION: Patients who underwent pancreatoduodenectomy for either PDAC or dCCA and who experienced an MPC had lower rates of adjuvant therapy and worse RFS, suggesting that clinicians adopt a standard neoadjuvant systemic therapy strategy in patients with PDAC. Our results propose a paradigm shift towards preoperative systemic therapy in patients with dCCA.

BACKGROUND: Primary sclerosing cholangitis (PSC) patients have a risk of developing cholangiocarcinoma (CCA). Establishing predictive models for CCA in PSC is important. METHODS: In a large cohort of 1,459 PSC patients seen at Mayo Clinic (1993-2020), we quantified the impact of clinical/laboratory variables on CCA development using univariate and multivariate Cox models and predicted CCA using statistical and artificial intelligence (AI) approaches. We explored plasma bile acid (BA) levels' predictive power of CCA (subset of 300 patients, BA cohort). RESULTS: Eight significant risk factors (false discovery rate: 20%) were identified with univariate analysis; prolonged inflammatory bowel disease (IBD) was the most important one. IBD duration, PSC duration, and total bilirubin remained significant (p < 0.05) with multivariate analysis. Clinical/laboratory variables predicted CCA with cross-validated C-indexes of 0.68-0.71 at different time points of disease, significantly better compared to commonly used PSC risk scores. Lower chenodeoxycholic acid, higher conjugated fraction of lithocholic acid and hyodeoxycholic acid, and higher ratio of cholic acid to chenodeoxycholic acid were predictive of CCA. BAs predicted CCA with a cross-validated C-index of 0.66 (std: 0.11, BA cohort), similar to clinical/laboratory variables (C-index = 0.64, std: 0.11, BA cohort). Combining BAs with clinical/laboratory variables leads to the best average C-index of 0.67 (std: 0.13, BA cohort). CONCLUSIONS: In a large PSC cohort, we identified clinical and laboratory risk factors for CCA development and demonstrated the first AI based predictive models that performed significantly better than commonly used PSC risk scores. More predictive data modalities are needed for clinical adoption of these models.

BACKGROUND: Intrahepatic cholangiocarcinoma (ICC) can be divided into two morphological subtypes: large duct type and small duct type ICC. This study aims to verify the feasibility of the classification criteria and clinicopathological characteristics of ICC. RESEARCH DESIGN AND METHODS: ICC patients were divided into the large and small type ICC by morphological and immunohistochemical patterns. Subsequently, clinicopathological data of the two groups was compared and the multivariate COX regression was used to verify the clinical significance of ICC subtypes. In addition, IDH1/2 mutation, KRAS mutation and FGFR2 translocation was also evaluated. RESULTS: Totally, 32, 61 and 13 tumors were defined as large, small and the indeterminate-duct type ICC respectively. Clinicopathologically, the large and small duct type ICC showed distinct morphological features. Compared with the small duct type ICC, the large duct type ICC had higher levels of serum tumor markers, vascular invasion, lymph node metastasis, and postoperative recurrence. Furthermore, positive FGFR2 rearrangement occurred only in small duct type ICC and IDH1/2 was mutated mainly in small duct type ICC. CONCLUSIONS: The subclassification system was applicable and the ICC subtypes had distinct clinicopathological characteristics, prognostic outcome, and IDH1/2 mutation pattern.
