Abstract
PURPOSE The Liver Imaging Reporting and Data System (LI-RADS) was created to standardize the diagnostic criteria for hepatocellular carcinoma (HCC) and has undergone multiple revisions including a recent update in 2018 (v2018). The primary aim of this study was to determine the diagnostic performance and interrater reliability (IRR) of LI-RADS v2018 for distinguishing HCC from non-HCC primary hepatic malignancy in patients 'at-risk' for HCC. A secondary aim was to assess the impact of changes introduced in the v2018 diagnostic algorithm. METHODS This retrospective study combined a 10-year experience of pathologically proven primary liver malignancies from two large liver transplant centers. Two blinded readers independently evaluated each lesion and assigned a LI-RADS diagnostic category, additionally scoring all relevant imaging features. Changes in category based on the reader-provided features and the new v2018 criteria were assessed by a study coordinator. RESULTS The final study cohort comprised 105 HCCs and 73 non-HCC primarily liver malignancies. LI-RADS had a high specificity for distinguishing HCC from non-HCC (89% and 90% for reader 1 and reader 2, respectively), and IRR was moderate to substantial for final LI-RADS category and most features. Revision of the LI-RADS v2018 diagnostic algorithm resulted in very few changes [5 (2.8%) and 3 (1.7%) for reader 1 and reader 2, respectively] in overall lesion classification. CONCLUSION LI-RADS diagnostic categories and features had moderate to substantial IRR and high specificity for distinguishing HCC from non-HCC primary liver malignancy. Revision of LI-RADS v2018 diagnostic algorithm resulted in reclassification of very few lesions.

Abstract
Combined hepatocellular-cholangiocarcinomas (CHC) are mixed tumours with both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC) components. CHC prognosis is similar to intrahepatic CC (ICC) and worse than HCC; staging and treatment generally follow ICC algorithms. However, the molecular biology of CHC remains poorly characterised. We performed capture-based next-generation sequencing of 20 CHC and, for comparison, 10 ICC arising in cirrhosis. Intratumour heterogeneity was assessed by separately sequencing the HCC and CC components of nine CHC. CHC demonstrated molecular profiles similar to HCC, even in the CC component. CHC harboured recurrent alterations in TERT (80%), TP53 (80%), cell cycle genes (40%; CCND1, CCNE1, CDKN2A), receptor tyrosine kinase/Ras/PI3-kinase pathway genes (55%; MET, ERBB2, KRAS, PTEN), chromatin regulators (20%; ARID1A, ARID2) and Wnt pathway genes (20%; CTNNB1, AXIN, APC). No CHC had alterations in IDH1, IDH2, FGFR2 or BAP1, genes typically mutated in ICC. TERT promoter mutations were consistently identified in both HCC and CC components, supporting TERT alteration as an early event in CHC evolution. TP53 mutations were present in both components in slightly over half the TP53-altered cases. By contrast, focal amplifications of CCND1, MET and ERRB2, as well as Wnt pathway alterations, were most often exclusive to one component, suggesting that these are late events in CHC evolution. ICC in cirrhosis demonstrated alterations similar to ICC in non-cirrhotic liver, including in IDH1 or IDH2 (30%), CDKN2A (40%), FGFR2 (20%), PBRM1 (20%), ARID1A (10%) and BAP1 (10%). TERT promoter and TP53 mutation were present in only one ICC each. Our data demonstrate that CHC genetics are distinct from ICC (even in cirrhosis) and similar to HCC, which has diagnostic utility and implications for treatment.

Abstract
BACKGROUND Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare primary liver malignancy. We conducted a systematic review and meta-analysis to assess the evidence available on the long-term outcomes of cHCC-CC patients after either hepatectomy or liver transplantation (LT). DATA SOURCES Relevant studies published between January 2000 and January 2018 were identified by searching PubMed and Embase and reviewed systematically. Data were pooled using a random-effects model. RESULTS A total of 42 observational studies involving 1691 patients (1390 for partial hepatectomy and 301 for LT) were included in the analysis. The median tumor recurrence and 5-year overall survival (OS) rates were 65% (range 38%-100%) and 29% (range 0-63%) after hepatectomy versus 54% (range 14%-93%) and 41% (range 16%-73%) after LT, respectively. Meta-analysis found no significant difference in OS and tumor recurrence between LT and hepatectomy groups. CONCLUSION Hepatectomy rather than LT should be considered as the prior treatment option for cHCC-CC.

Abstract
INTRODUCTION Mixed hepatocellular cholangiocarcinoma (HCC-CC) represents a rare hepatic tumor, which demonstrates histological features of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). HCC-CC can be an unexpected finding in patients undergoing liver transplantation (LT) for HCC. The objective of our review was to review and evaluate long-term outcomes in patients undergoing LT for mixed HCC-CC. METHODS A meticulous MEDLINE search was performed for articles referring to long-term results in patients who underwent LT and whose final pathology revealed HCC-CC. RESULTS A total of 7 studies, which comprised 93 patients who underwent LT and whose resected specimen revealed mixed HCC-CC, were included in our review. One-year overall survival (OS) rates ranged from 64% to 93%, 3-year OS ranged from 38% to 78%, and 5-year OS rates range from 14% to 78%. Disease-free-survival (DFS) rates at 1-year from LT ranged from 60-% to 64%, whereas both 3- and 5-year DFS rates ranged from 30% to 53.3%. CONCLUSIONS Long-term results of LT in the setting of mixed HCC-CC are associated with fairly unfavorable overall outcomes compared to LT for other indications including HCC yet are improved compared to others such as intrahepatic CC. A stricter preoperative evaluation could potentially help identify the patients with mixed HCC-CC who are at high-risk after LT, reduce the risks of recurrence, and improve OS.

Abstract
Combined hepatocellular cholangiocarcinoma (CC) is a rare and aggressive primary hepatic malignancy with significant histological and biological heterogeneity. It presents with more aggressive behavior and worse survival outcomes than either hepatocellular carcinoma or CC and remains a diagnostic challenge. An accurate diagnosis is crucial for its optimal management. Major hepatectomy with hilar node resection remains the mainstay of treatment in operable cases. Advances in the genetic and molecular characterization of this tumor will contribute to the better understanding of its pathogenesis and shape its future management.

How to utilize LR-M features of the LI-RADS to improve the diagnosis of combined hepatocellular-cholangiocarcinoma on gadoxetate-enhanced MRI? Eur Radiol 2018; 29:2408-2416. [PMID: 30552477 DOI: 10.1007/s00330-018-5893-1] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Revised: 10/23/2018] [Accepted: 11/14/2018] [Indexed: 12/21/2022]
Abstract
OBJECTIVES To investigate the diagnostic accuracy of each LR-M feature defined in version 2017 of the Liver Imaging Reporting and Data System (LI-RADS) and determine the optimal LR-M feature for differentiating combined hepatocellular-cholangiocarcinoma (cHCC-CCA) and hepatocellular carcinoma (HCC) on gadoxetate-enhanced magnetic resonance imaging (MRI). METHODS Ninety-nine patients with pathologically proven cHCC-CCA (n = 33) or HCC (n = 66) after surgery were identified. Two radiologists retrospectively assessed preoperative gadoxetate-enhanced MRI for features favoring non-HCC malignancies (LR-M features) according to LI-RADS version 2017. Multivariate logistic regression analysis was performed to determine the independent differential features. The sensitivity and specificity for diagnosing cHCC-CCA were calculated for each LR-M feature. RESULTS Targetoid appearance showed the highest sensitivity (75.8%, 95% confidence interval [CI] 60.6%, 87.3%) to correctly identify cHCC-CCA as LR-M. At least one LR-M feature was observed in 31 (93.9%) patients with cHCC-CCA and 34 (51.5%) patients with HCC. The sensitivity and specificity for diagnosing cHCC-CCA using the presence of any one of the LR-M features were 93.9% (95% CI 80.7, 98.9) and 48.5% (95% CI 41.9, 51.0), respectively. The presence of three LR-M features yielded the highest diagnostic accuracy of 80.8% (95% CI 72.1, 86.1) with a reduced sensitivity of 54.5% (95% CI 41.4, 62.5). CONCLUSION The majority of cHCC-CCA cases can be properly categorized as LR-M when any one of the LR-M features defined in the LI-RADS version 2017 is used as a determiner. However, approximately half of HCC cases also show at least one LR-M feature. KEY POINTS • Targetoid appearance, including rim APHE, peripheral "washout" appearance, and delayed central enhancement, was the LR-M feature that identified cHCC-CCA as a non-HCC malignancy with the highest sensitivity. • Most cHCC-CCA cases can be properly categorized as LR-M when the presence of any one of the LR-M features was used as the determiner. • Approximately half of HCC cases also showed at least one LR-M feature.

Abstract
PURPOSE OF REVIEW To review the recent consensus on the nomenclature, clinical features, diagnosis, and treatment of combined hepatocellular carcinoma-cholangiocarcinoma (cHCC-CCA). RECENT FINDING cHCC-CCA is a primary liver carcinoma with varying degrees of hepatocytic and cholangiocytic cytology and architecture within the same tumor. The diagnosis of cHCC-CCA can only be established based on histologic examination. Surgical resection should be considered in patients with resectable tumors who do not have underlying liver disease or clinically significant portal hypertension. While treatment by liver transplantation (LT) is controversial due to the high risk of post LT recurrence, LT should remain as a potentially curative option in a highly selected group of patients. Little data exist for the outcome of other treatments. SUMMARY High quality multicenter prospective studies should be conducted to better understand this rare, but increasingly recognized tumor.

Abstract
Background Patients with solid organ transplants (SOTs) have been excluded from programmed death protein-1 (PD-1)/programmed death ligand-1 (PD-L1) inhibitor clinical trials due to concern for allograft rejection. The use of immune checkpoint inhibitor therapy remains controversial in transplant patients. Methods A retrospective pilot evaluation was conducted to assess the safety and efficacy of PD-1 inhibitors in patients with liver transplantation (LT). The primary endpoint was the rate of allograft rejection. Secondary endpoints included overall response rate (ORR), progression free survival (PFS) and overall survival (OS). Translational objectives included evaluation of tumor PD-L1, tumor infiltrating lymphocytes (TILs) and allograft PD-L1 expression. Results Seven metastatic cancer patients with a history of LT who received PD-1 inhibitor therapy were included [hepatocellular carcinoma (HCC), n=5; melanoma, n=2]. Rejection was observed in 2 of 7 patients. When rejection occurs it appears to be an early event with a median time to rejection of 24 days in our cohort. One patient achieved a complete response (CR), 3 patients had progressive disease (PD) and 3 patients discontinued therapy prior to restaging assessments. Two of five patients with available tissue had PD-L1 expression in the allograft and both developed rejection. One of five evaluable patients had abundant TILs. Two of five evaluable patients had PD-L1 tumor staining. The single patient with both abundant TILs and PD-L1 staining obtained a response. The median OS and PFS were 1.1 (0.3-21.1) and 1.8 (0.7-21.1) months, respectively. Conclusions In this pilot evaluation both preliminary efficacy (1 of 4) and allograft rejection (2 of 7) were exhibited in evaluable patients. Larger, prospective trials are needed to elucidate optimal patient selection.

Abstract
Mixed hepatocellular-cholangiocarcinomas (HCC-CCAs) are rare tumors with both hepatocellular and biliary differentiation. While liver transplantation (LT) is the gold standard treatment for patients with unresectable hepatocellular carcinoma (HCC), it is contraindicated in known HCC-CCA because of concerns of poor prognosis. We sought to compare posttransplant oncologic outcomes for HCC-CCA and a matched cohort of HCC LT recipients. A retrospective, single-center analysis (1984-2015) identified 12 patients with mixed HCC-CCA who were matched 1:3 to patients with HCC on both pretransplant (radiologic diameter and alpha-fetoprotein) and explant (pathologic diameter, grade/differentiation, and vascular invasion) tumor characteristics. Compared with HCC patients matched on pretransplant characteristics (n = 36), HCC-CCA had higher explant tumor grade, more poorly differentiated tumors, but similar T stage and vascular invasion. HCC-CCA recipients trended toward inferior recurrence-free survival at 5 years (28% versus 61%; P = 0.12) and greater recurrence (HCC-CCA: 50%, median time to recurrence 297 days versus HCC: 22%, median time to recurrence 347 days; P = 0.07). However, when matched to a separate HCC cohort with similar explant pathology, HCC-CCA had similar 5-year recurrence-free survival (42% versus 44%; P = 0.45) and posttransplant recurrence (50% versus 27%; P = 0.13). All 6 HCC-CCA recurrences occurred with poorly differentiated tumors (median survival 21.3 months), without a single recurrence in 5 of the 12 HCC-CCA patients with well-moderately differentiated tumors (median survival 60.2 months). Mixed HCC-CCA tumors are more likely poorly differentiated tumors compared with HCC with similar pretransplant characteristics. However, compared with HCC with similar pathologic characteristics, they display similar recurrence-free survival and are not inherently more aggressive tumors. Low-grade, well-moderately differentiated HCC-CCAs have excellent survival with a low risk for post-LT recurrence, and they should not be excluded from LT. Improved pretransplant identification of pathologic characteristics in HCC-CCA may allow for successful utilization of LT in this subset of patients.

Abstract
Background Combined hepatocellular-cholangiocarcinoma (cHCC-CC) can present as a hypervascular or peripherally enhancing tumor in dynamic imaging. We evaluated the effect of transarterial chemoembolization (TACE) on prognosis according to post-operative recurrence imaging patterns. Methods We retrospectively analyzed 42 cHCC-CC and 59 hepatocellular carcinoma (HCC-control) patients at the Asan Medical Center. We classified recurrent cHCC-CC according to enhancement pattern (globally enhancing: GE cHCC-CC, peripherally enhancing: PE cHCC-CC) and evaluated tumor response, time-to-local progression (TTPlocal), and overall survival (OS). Results The GE cHCC-CC group had a significantly higher best objective response rate (complete remission + partial response) than the PE cHCC-CC group (36% vs 0%, P = 0.005), and it was comparable to that of the HCC-control group (35.6%, P = 0.97). TTPlocal in the GE cHCC-CC group was significantly shorter than in the HCC-control group (6.6 vs 27.1 months, P < 0.001), and was not significantly different from that in the PE cHCC-CC group (5.3 months, P = 0.12). OS was 12.4 months, 52.8 months, and 67.5 months in the PE cHCC-CC, GE cHCC-CC, and HCC-control groups, respectively (Ps < 0.05). The adjusted hazard ratios (HRs) for TTPlocal and OS revealed an independent association with enhancement pattern of recurrent cHCC-CC (TTPlocal: HR 2.46; 95% CI 1.10–5.46; P = 0.03; OS: HR 5.97; 95% CI 2.38–14.96; P < 0.001). Conclusions The GE cHCC-CC group showed better response and prognosis after TACE than the PE cHCC-CC group, but poorer response and prognosis than the HCC-control group. Enhancement patterns at recurrence were crucially associated with tumor response and overall survival.

Abstract
Although hepatocellular carcinoma (HCC) has become a common indication for liver transplantation (LT), intrahepatic cholangiocarcinoma (ICC) and combined hepatocellular carcinoma-cholangiocarcinoma (cHCC-CCA) are historically contraindicated due to their aggressive behavior. On the basis of recent experiences, some groups have proposed a clinical trial investigating the role of LT for patients with early cholangiocarcinoma (CCA), defined as a single lesion ≤ 2 cm. The purpose of this study is to assess the clinicopathologic features and outcomes following LT for patients who were initially diagnosed with HCC and subsequently found to have either ICC or cHCC-CCA on explant. Patients with the diagnosis of primary liver cancer (PLC) after LT from a single center were retrospectively reviewed. Outcomes for patients with early CCA were compared with patients with HCC within Milan criteria (MC). Out of 618 patients transplanted with PLC, 44 patients were found to have CCA on explant. On the basis of preoperative imaging, 12 patients met criteria for early CCA and were compared with 319 patients who had HCC within MC. The 1- and 5-year overall survival for early CCA versus HCC was 63.6% versus 90.0% and 63.6% versus 70.3% (log-rank, P = 0.25), respectively. Overall recurrence was 33.3% for early CCA versus 11% for HCC. On explant the patients with CCA were more likely understaged with higher tumor grade and vascular invasion. In conclusion, patients with CCA present a diagnostic challenge, which often leads to the finding of more aggressive lesions on explant after LT, higher recurrence rates, and worse post-LT survival. Careful consideration of this diagnostic conundrum needs to be made before a clinical trial is undertaken. Liver Transplantation 24 634-644 2018 AASLD.

Surgical Treatment of Combined Hepatocellular-Cholangiocarcinoma is as Effective in Elderly Patients as it is in Younger Patients: A Propensity Score Matching Analysis. J Cancer 2018; 9:1106-1112. [PMID: 29581790 PMCID: PMC5868178 DOI: 10.7150/jca.23921] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2017] [Accepted: 01/28/2018] [Indexed: 12/11/2022] Open
Abstract
Aims: To compare the long-term prognosis of younger and elderly patients with combined hepatocellular-cholangiocarcinoma (CHC) who underwent curative resection between 1993 and 2014 at our center. Methods: Two hundred and thirteen patients who underwent liver resection for CHC were enrolled in our study. The overall survival (OS) and disease-free survival (DFS) of elderly patients (age≥60, n=52) and younger patients (age<60, n=161) were compared by multivariate analysis and propensity score matching (PSM) analysis. Results: Among the 213 CHC patients, the elderly patients had a higher rate of worse Child-Pugh grade (P=0.027), abnormal serum albumin (P<0.001) and lymphoid metastases (P=0.024). The proportion of HBV-positive CHC patients (74.6%, 159/213) was much higher than that observed in healthy cohorts. Younger patients had a higher rate of hepatitis B virus (HBV) infection compared to older patients (83.9% vs 46.2%, P<0.001). OS and DFS of the elderly and younger patients before and after propensity score matching were comparable. Conclusion: Elderly and younger patients who underwent liver resection for CHC have comparable long-term OS and DFS.

Abstract
Cholangiocarcinoma (CCA) is the second most common liver cancer, and it is associated with a poor prognosis. CCA can be divided into intrahepatic, hilar, and distal. Despite the subtype, the median survival is 12-24 months without treatment. Liver transplantation (LT) is recognized worldwide as a curative option for hepatocellular carcinoma. On the other hand, the initial results for LT for CCA were very poor mainly due to a lack of adequate patient selection. In the last 2 decades, improvements have been made in the management of unresectable hilar CCA, and the results of LT after neoadjuvant chemoradiation have been shown to be promising. This has prompted a consideration of hilar CCA as an indication for LT in some centers. Furthermore, some recent research has shown promising results after LT for patients with early stages of intrahepatic CCA. A better understanding of the best tools to prognosticate the outcomes of LT for CCA is still needed. Here, we aimed to review the role of LT for the treatment of patients with perihilar and intrahepatic CCA. Also, we will discuss the most recent advances in the field and the future direction of the management of this disease in an era of transplantation oncology.

Abstract
Organ shortage requires policies and guidelines to aid organ allocation along the principles of urgency or utility. Identifying patients with significant benefit and withholding liver transplantation (LT) from patients too sick for transplantation are ongoing challenges, in particular in patients with malignancies. An arbitrary threshold of >50% 5-year overall survival (OS) is broadly considered a minimum standard for LT. In patients transplanted for intrahepatic cholangiocarcinoma (iCC), this was only achieved in select cases and when the tumor had a diameter of <2 cm. In patients with extrahepatic and hilar cholangiocarcinoma (CCC), strict selection criteria and combined preoperative radiotherapy/chemotherapy according to the Mayo protocol showed that acceptable longterm results can be achieved in a single high-volume center but are difficult to repeat elsewhere. Furthermore, only rigorously selected patients with neuroendocrine tumors (NETs) meeting the NET Milan criteria adopted by United Network for Organ Sharing can also have >50% 5-year OS. A prospective study in patients with unresectable colorectal cancer metastases in the liver has shown promising OS rates, but further prospective trials are warranted. Current evidence shows that none of the proposed expanded malignant criteria justify deviation of scarce donor organs to patients with hilar CCC, iCC > 2 cm, metastatic NET beyond NET Milan criteria, or metastatic colorectal cancer (CRC) outside clinical trials.

Abstract
Background: Hepatocholangiocarcinoma (cHCC-ICC) is a rare liver tumour for which no data on chemosensitivity exist. The aims of this multicentre study were to evaluate overall survival (OS), progression-free survival (PFS), and prognostic factors in cHCC-ICC treated by gemcitabine plus platinum as first-line. Methods: Unresectable cHCC-ICC treated by gemcitabine plus platinum-based chemotherapy between 2008 and 2017 were retrospectively analysed. Diagnosis was based on histology or, in case of ICC or HCC histology, on discordant computerised tomography scan enhancement patterns associated with discordant serum tumour marker elevation suggesting the alternative tumour. OS and PFS were evaluated by Kaplan–Meier method and prognostic factors by Log-rank test and Cox model. Results: Among 30 patients included, cHCC-ICC was histologically proven in 22 (73.3%). 18 (60%) received gemcitabine plus oxaliplatin (GEMOX), 9 (30%) GEMOX plus bevacizumab, and 3 (10%) gemcitabine plus cisplatin. RECIST criteria were reported in 28 patients: 8 (28.6%) showed partial response, 14 (50%) stable disease, and 6 (21.4%) tumour progression at first evaluation. Median PFS and OS were 9.0 and 16.2 months, respectively. Serum bilirubin ⩾30 μmol l−1 (P=0.001) and positive serology for HBV and/or HCV (P=0.014) were independent poor prognostic factors for OS. Conclusions: Gemcitabine plus platinum-based chemotherapy is effective as first-line for advanced cHCC-ICC.

Abstract
BACKGROUND Reports of liver transplantation (LT) in patients with mixed hepatocellular carcinoma/cholangiocarcinoma (HCC/CC) and intrahepatic cholangiocarcinoma (ICC) are modest and have been mostly retrospective after pathological categorization in the setting of presumed HCC. Some studies suggest that patients undergoing LT with small and unifocal ICC or mixed HCC/CC can achieve about 40%-60% 5-year post-transplant survival. The study aimed to report our experience in patients undergoing LT with explant pathology revealing HCC/CC and ICC. METHODS From a prospectively maintained database, we performed cohort analysis. We identified 13 patients who underwent LT with explant pathology revealing HCC/CC or ICC. RESULTS The observed recurrence rate post-LT was 31% (4/13) and overall survival was 85%, 51%, and 51% at 1, 3 and 5 years, respectively. Disease-free survival was 68%, 51%, and 41% at 1, 3 and 5 years, respectively. In our cohort, four patients would have qualified for exception points based on updated HCC Organ Procurement and Transplantation Network imaging guidelines. CONCLUSIONS Lesions which lack complete imaging characteristics of HCC may warrant pre-LT biopsy to fully elucidate their pathology. Identified patients with early HCC/CC or ICC may benefit from LT if unresectable. Additionally, incorporating adjunctive perioperative therapies such as in the case of patients undergoing LT with hilar cholangiocarcinoma may improve outcomes but this warrants further investigation.

Abstract
BACKGROUND Combined hepatocellular-cholangiocarcinoma (HCC-CC) has a reported incidence of less than 5% of primary hepatic malignancies. The treatment approach to this malignancy is undefined. Our objective of this case series is to provide some insight into chemotherapy and/or targeted therapy in this setting. METHODS Pathologic and radiographic review confirmed seven combined HCC-CC patients during a 5-year time frame [2009-2014]. Data points were demographics, chemotherapy and/or targeted therapy given in the first and second-line setting, localized treatment if given, first radiographic result, progression-free survival (PFS), and overall survival (OS). RESULTS Seven patients were identified. Front-line treatment showed a median PFS of 3.4 months. Total median OS was 8.3 months. Regimens given included gemcitabine alone +/- bevacizumab, gemcitabine + platinum (GP) +/- bevacizumab, and sorafenib. Front-line treatment with these regimens showed progressive disease in 71% (5 patients) on first radiographic scan with all patients who received sorafenib front-line progressing at that restaging. Disease-control (complete response + partial response + stable disease) was seen in 29% of patients (2 patients) with 1 patient receiving GP and 1 patient receiving gemcitabine + bevacizumab. Of note, 2 patients that received GP +/- bevacizumab in the second-line setting had disease control on first radiographic scan. CONCLUSIONS Our retrospective review speaks to the rarity of this malignancy and challenges that are associated with its diagnosis and treatment. GP +/- bevacizumab showed disease control in first or second-line treatment in 3 patients. Treatment with this regimen in this rare malignancy subgroup warrants further investigation.

Abstract
Combined hepatocellular carcinoma-cholangiocarcinoma (cHCC-CC) is a rare disease. We investigated the clinicopathological features of cHCC-CC and compared the longterm outcomes following liver transplantation (LT) and hepatic resection (HR). We identified 32 LT patients with cHCC-CC through an institutional database search. The HR control group (n = 100) was selected through propensity score-matching. The incidence of cHCC-CC among all adult LT patients was 1.0%. Mean patient age was 53.4 ± 6.7 years, and 26 patients were male. Thirty patients had hepatitis B virus infection. All patients of cHCC-CC were diagnosed incidentally in the explanted livers. Mean tumor diameter was 2.5 ± 1.3 cm, and 28 patients had single tumors. Tumor stage was stage I in 23 and II in 9. Concurrent hepatocellular carcinoma (HCC) was detected in 12 patients with stage I in 5 and II in 7. Mean tumor diameter was 1.9 ± 1.2 cm, and 5 had single tumors. Tumor recurrence and survival rates were 15.6% and 84.4% at 1 year and 32.2% and 65.8% at 5 years, respectively. Patients with very early stage cHCC-CC (1 or 2 tumors ≤ 2.0 cm) showed 13.3% tumor recurrence and 93.3% patient survival rates at 5 years, which were significantly improved than those with advanced tumors (P = 0.002). Tumor recurrence and survival rates did not differ significantly between the LT and HR control groups (P = 0.22 and P = 0.91, respectively); however, postrecurrence patient survival did (P = 0.016). In conclusion, cHCC-CC is rarely diagnosed following LT, and one-third of such patients have concurrent HCC. The longterm posttransplant prognosis was similar following LT and HR. Very early cHCC-CC resulted in favorable posttransplant prognosis, thus this selection condition can be prudently considered for LT indication. Liver Transplantation 23 330-341 2017 AASLD.

Abstract
Combined hepatocellular-cholangiocarcinoma (CHC) is a rare tumor with poor prognosis, with incidence ranging from 1.0%-4.7% of all primary hepatic tumors. This entity will be soon renamed as hepato-cholangiocarcinoma. The known risk factors for hepatocellular carcinoma (HCC) have been implicated for CHC including viral hepatitis and cirrhosis. It is difficult to diagnose this tumor pre-operatively. The predominant histologic component within the tumor largely determines the predominant radiographic features making it a difficult distinction. Heterogeneous and overlapping imaging features of HCC and cholangiocarcinoma should raise the suspicion for CHC and multiple core biopsies (from different areas of tumor) are recommended before administering treatment. Serum tumor markers CA19-9 and alpha-fetoprotein can aid in the diagnosis, but it remains a challenging diagnosis prior to resection. There is sufficient data to support bipotent hepatic progenitor cells as the cell of origin for CHC. The current World Health Organization classification categorizes two main types of CHC based on histo-morphological features: Classical type and CHC with stem cell features. Liver transplant is one of the available treatment modalities with other management options including transarterial chemoembolization, radiofrequency ablation, and percutaneous ethanol injection. We present a review paper on CHC highlighting the risk factors, origin, histological classification and therapeutic modalities.

No Evidence That Azathioprine Increases Risk of Cholangiocarcinoma in Patients With Primary Sclerosing Cholangitis. Clin Gastroenterol Hepatol 2016; 14:1806-1812. [PMID: 27521513 DOI: 10.1016/j.cgh.2016.07.032] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Revised: 07/11/2016] [Accepted: 07/26/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Patients with primary sclerosing cholangitis (PSC) are at increased risk for developing cholangiocarcinoma (CCA). Patients with PSC also can have inflammatory bowel diseases (IBDs) or features of autoimmune hepatitis (AIH), and therefore are treated with azathioprine. Azathioprine has been associated with an increased risk for malignancy, therefore we investigated whether azathioprine use affects the risk of CCA in persons with PSC. METHODS We performed a retrospective study of well-defined patients with PSC using data collected from 3 large-volume, tertiary care centers in Germany and Norway. We analyzed data from 638 patients (70% men; 5900 patient-years of follow-up evaluation); 91 patients had received azathioprine therapy (considered to be effective at 90 days after first intake). Risk analysis was performed using the Cox proportional hazard model when risks competing with study end points were present. RESULTS Of patients who received azathioprine treatment, 3.3% developed CCA, compared with 6.8% of patients without azathioprine treatment. However, azathioprine did not significantly affect the risk for CCA (hazard ratio, 0.96; 95% confidence interval, 0.29-3.13; P = .94). The only factor associated with an increased risk of CCA was age 35 years or older at PSC diagnosis (hazard ratio, 3.87; 95% confidence interval, 1.96-7.67; P < .01). Patient sex, concomitant IBD, or AIH did not affect the risk of CCA. Overall, the cumulative 10-year incidence of CCA was 4.6% and the cumulative 15-year incidence was 7.7%. CONCLUSIONS A retrospective analysis of patients with PSC treated at tertiary centers in Europe found no evidence that azathioprine significantly affects the risk of CCA. Azathioprine therefore should not be withheld from patients with PSC and concomitant IBD and/or AIH.

Abstract
BACKGROUND Intrahepatic lesions of mixed hepatocellular (HCC) and intrahepatic cholangiocellular carcinoma (ICC) histology are rare. The aim was to describe the natural history of these tumors relative to monomorphic ICC or HCC utilizing the National Cancer Data Base (NCDB). METHODS Patients with ICC, HCC, and mixed histology (cHCC-CCA) were identified in the NCDB (2004-2012). Inter-group comparisons were made. Kaplan-Meier and multivariable Cox Proportional Hazards analyzed overall survival. RESULTS The query identified 90,499 patients with HCC; 14,463 with ICC; and 1141 with cHCC-CCA histology. Patients with cHCC-CCA histology were relatively young (61 vs. 62 (HCC, p = 0.877) and 67 (ICC, p < 0.001) years) and more likely to have poorly differentiated tumor (29.2% vs. 10.3% (HCC) and 17.2% (ICC) p < 0.001). Median overall survival for cHCC-CCA was 7.9 months vs. 10.8 (HCC) and 8.2 (ICC, all p < 0.001). Stage-specific survival for mixed histology tumors was most similar to that of HCC for all stages. cHCC-CCA were transplanted at a relatively high rate, and transplant outcomes for mixed tumors were substantially worse than for HCC lesions. DISCUSSION cHCC-CCA demonstrate stage-specific survival similar to HCC, but post-surgical survival more consistent with ICC. Patients with a pre-operative diagnosis of cHCC-CCA should undergo resection when appropriate.

Abstract
Combined hepatocellular cholangiocarcinoma (CHC) accounts for 0.4%-14.2% of primary liver cancer cases and possesses pathological features of both hepatocellular carcinoma and cholangiocarcinoma. Since this disease was first described and classified in 1949, the classification of CHC has continuously evolved. The latest definition and classification of CHC by the World Health Organization is based on the speculation that CHC arises from hepatic progenitor cells. However, there is no evidence demonstrating the common origin of different components of CHC. Furthermore, the definition of CHC subtypes is still ambiguous and the identification of CHC subtype when a single tumor contains many components has remained unresolved. In addition, there is no summary on the newly recognized histopathology features or the contribution of CHC components to prognosis and outcome of this disease. Here we provide a review of the current literature to address these questions.
