Abstract
BACKGROUND Hypertension is a risk factor for cholangiocarcinoma (CCA). The effect of anti-hypertensive drugs on the prognosis of CCA is not clear. METHODS This is a retrospective study of 102 patients (56.9% males, median age 66 years) diagnosed with CCA and hypertension concurrently and received radical surgery (R0), with a median follow-up of 36.7 months. Kaplan-Meier analysis, Cox regressions, and propensity score (PS) matching were applied for statistical analysis. RESULTS Results of multivariable cox analysis showed that renin-angiotensin system inhibitors (RASis) usage was a protective factor for progression-free survival (PFS) (hazard ratio [HR] = 0.55, 95% confidence interval [95% CI]: 0.32-0.96) and overall survival (OS) (HR = 0.40, 95% CI: 0.20-0.79), respectively. Calcium channel blockers, diuretics, and β-blockers didn't show significant associations. The association of RASis usage and PFS and OS was derived by PS matching, with a cohort of 28 RASis users and 56 RASis non-users. The median PFS and OS of RASis users (PFS, 17.6 months (9.2-34.4); OS, 24.8 months (16.5-42.3)) were longer than RASis non-users (PFS, 10.5 months (4.1-24.1); OS, 14.6 months (10.6-28.4)). The 1 year, 2 years, and 3 years' survival rates of RASis users (89.1%, 77.0%, and 65.5%) were higher than RASis non-users (70.9%, 54.0%, and 40.0%). CONCLUSIONS RASis usage improves the survival of patients with CCA and hypertension concurrently.

Zheng Z, Fang L, Cai H. Cost-effectiveness analysis of pembrolizumab in combination with chemotherapy compared with chemotherapy alone as first-line treatment for patients with advanced biliary tract cancer in China. BMC Cancer 2023; 23:823. [PMID: 37667230 PMCID: PMC10476407 DOI: 10.1186/s12885-023-11255-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 08/04/2023] [Indexed: 09/06/2023] Open
Abstract
OBJECTIVE The objective of this study is to evaluate the cost-effectiveness of adding pembrolizumab to the standard first-line therapy of advanced biliary tract cancer (BTC) with gemcitabine and cisplatin from the perspective of the Chinese healthcare system. METHODS The partitioned survival model developed from clinical data obtained in The KEYNOTE-966 trial served as the basis for a simulation in the TreeAge Pro 2011 software. The objective of the research was to estimate the 10-year life expectancy and total healthcare costs of patients with BTC, utilizing primary outcomes that evaluated costs, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratio (ICER). To establish the willingness-to-pay (WTP) threshold, the 2022 Chinese per capita gross domestic product (GDP) of $37304.346/QALY was adopted. Furthermore, sensitivity analysis was conducted to ascertain the study's results under varying levels of uncertainty. RESULTS Compared to chemotherapy alone, the addition of pembrolizumab to chemotherapy has been shown to yield an incremental gain of 0.184 quality-adjusted life years (QALY) at an additional cost of $103940.706. This translates into an incremental cost-effectiveness ratio (ICER) of $564895.141/QALY, which exceeds the willingness-to-pay (WTP) threshold in China. One-way sensitivity analyses performed on the model recognize the utility of PD, subsequent cost, and the cost of Pembrolizumab 100 mg had a major influence on the outcomes. However, no parameter elicited an ICER lower than the willingness-to-pay (WTP) threshold. CONCLUSIONS Based on the perspective of the Chinese healthcare system, the utilization of pembrolizumab in combination with chemotherapy as an first-line treatment option for BTC does not appear to be a cost-effective approach compared to chemotherapy as a standalone therapy.

Abstract
This study aimed to conduct a comprehensive analysis of actionable gene rearrangements in tumors with microsatellite instability (MSI). The detection of translocations involved tests for 5'/3'-end expression imbalance, variant-specific PCR and RNA-based next generation sequencing (NGS). Gene fusions were detected in 58/471 (12.3%) colorectal carcinomas (CRCs), 4/69 (5.8%) gastric cancers (GCs) and 3/65 (4.6%) endometrial cancers (ECs) (ALK: 8; RET: 12; NTRK1: 24; NTRK2: 2; NTRK3: 19), while none of these alterations were observed in five cervical carcinomas (CCs), four pancreatic cancers (PanCs), three cholangiocarcinomas (ChCs) and two ovarian cancers (OCs). The highest frequency of gene rearrangements was seen in KRAS/NRAS/BRAF wild-type colorectal carcinomas (53/204 (26%)). Surprisingly, as many as 5/267 (1.9%) KRAS/NRAS/BRAF-mutated CRCs also carried tyrosine kinase fusions. Droplet digital PCR (ddPCR) analysis of the fraction of KRAS/NRAS/BRAF mutated gene copies in kinase-rearranged tumors indicated that there was simultaneous co-occurrence of two activating events in cancer cells, but not genetic mosaicism. CRC patients aged above 50 years had a strikingly higher frequency of translocations as compared to younger subjects (56/365 (15.3%) vs. 2/106 (1.9%), p = 0.002), and this difference was particularly pronounced for tumors with normal KRAS/NRAS/BRAF status (52/150 (34.7%) vs. 1/54 (1.9%), p = 0.001). There were no instances of MSI in 56 non-colorectal tumors carrying ALK, ROS1, RET or NTRK1 rearrangements. An analysis of tyrosine kinase gene translocations is particularly feasible in KRAS/NRAS/BRAF wild-type microsatellite-unstable CRCs, although other categories of tumors with MSI also demonstrate moderate occurrence of these events.

Abstract
Primary liver cancers (PLCs) are a broad class of malignancies that include HCC, intrahepatic cholangiocarcinoma, and combined hepatocellular and intrahepatic cholangiocarcinoma. PLCs are often associated with a poor prognosis due to their high relapse and low therapeutic response rates. Importantly, PLCs exist within a dynamic and complex tumor ecosystem, which includes malignant, immune, and stromal cells. It is critical to dissect the PLC tumor ecosystem to uncover the underlying mechanisms associated with tumorigenesis, relapse, and treatment resistance to facilitate the discovery of novel therapeutic targets. Single-cell and spatial multi-omics sequencing techniques offer an unprecedented opportunity to elucidate spatiotemporal interactions among heterogeneous cell types within the complex tumor ecosystem. In this review, we describe the latest advances in single-cell and spatial technologies and review their applications with respect to dissecting liver cancer tumor ecosystems.

Pemetrexed and Erlotinib as a Salvage Treatment in Patients With Metastatic Biliary Tract Cancer Who Failed Gemcitabine-containing Chemotherapy: A Phase II Single-arm Prospective Study. Anticancer Res 2023; 43:4161-4167.

Abstract
BACKGROUND/AIM No standard treatment is currently recommended for advanced biliary tract cancer (BTC) after first-line therapy with gemcitabine plus cisplatin. We aimed to evaluate the efficacy and safety of a pemetrexed and erlotinib combination in patients with BTC previously treated with gemcitabine. PATIENTS AND METHODS This phase II, open-label, single-arm study enrolled patients with BTC who had previously failed gemcitabine-based first-line chemotherapy. Patients were treated with pemetrexed as a 500 mg/m2 intravenous infusion on day 1 for three weeks and erlotinib 100 mg daily until disease progression or unacceptable toxicity. The primary endpoint was the overall response rate (ORR). RESULTS The study enrolled 20 patients with BTC, including 12 (60%) with intrahepatic cholangiocarcinoma (IHCC), 3 (15%) with extrahepatic cholangiocarcinoma (EHCC), and 5 (25%) with gallbladder cancer (GBC). The ORR was 5%, and the disease control rate (DCR) was 55%. As of the cutoff point of March 31, 2023, the median progression-free survival (PFS) was 2.3 months [95% confidence interval (CI)=0.00-4.74] and the median overall survival (OS) was 5.6 months (95%CI=2.28-8.87). Patients with EHCC showed longer PFS and OS compared to patients with IHCC or GBC, but the differences were not significant. A baseline CEA greater than the upper normal limit was the only significant prognostic factor for a worse OS rate. The only treatment-related adverse event (TRAE) with severity grade ≥3 was anemia (5%). CONCLUSION Salvage chemotherapy with pemetrexed plus erlotinib was well-tolerated and showed marginal clinical activity in BTC patients after failure to gemcitabine-based chemotherapy.

Abstract
BACKGROUND/AIM Liver cancer constitutes one of the leading cancers globally. During pregnancy, however, liver cancer is an absolute rarity, with very few cases reported in the international literature. The aim of the present review was to provide a useful update and summarize all case studies of liver cancer in pregnancy published between 2012-2023. MATERIALS AND METHODS A literature review was conducted using the MEDLINE, LIVIVO, and Google Scholar databases. Solely case reports and case studies written in the English language that explicitly reported on the presence of histologically confirmed HCC or intrahepatic cholangiocarcinoma during pregnancy were included in the data analysis. RESULTS After detailed evaluation, a total of 35 reported cases of liver cancer during pregnancy were identified, hence bringing the total number of reported cases globally to 83. Oncological challenges during pregnancy call for an interdisciplinary approach. Although the desire to preserve the pregnancy should be taken into consideration, specialists need to evaluate maternal and fetal well-being and choose the optimal oncological treatment with the least dangers for both the maternal and fetal safety. CONCLUSION The present review proves that, despite its scarcity, liver cancer may always occur during pregnancy and clinicians should, therefore, remain vigilant and endeavor to detect and evaluate any hepatic mass or symptoms of liver cancer promptly and exhaustively.

Abstract
Primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) are 2 major liver autoimmune diseases. PBC is common in women and primarily affects intrahepatic small bile duct epithelial cells, known as cholangiocytes. In contrast, PSC is dominant in men and primarily affects medium and big intrahepatic and extrahepatic bile duct epithelial cells. Cholangiocarcinoma (CCA) is a malignancy arising from cholangiocytes, and its incidence is increasing worldwide in both men and women. Numerous retrospective and clinical studies have suggested that PBC patients rarely develop CCA compared to PSC patients. CCA is accountable for the higher deaths in PSC patients due to ineffective therapies and our inability to diagnose the disease at an early stage. Therefore, it is paramount to understand the differences in immune surveillance mechanisms that render PBC patients more resistant while PSC patients are susceptible to CCA development. Here, we review several potential mechanisms contributing to differences in the susceptibility to CCA in PBC versus PSC patients.

Abstract
BACKGROUND Although the role of adjuvant chemotherapy (CT) for resectable biliary tract cancer (BTC) is gradually recognized, the benefit of adjuvant chemoradiotherapy (CRT) is still controversial. Our study is designed to compare the prognosis of CRT versus CT in BCT patients. METHODS Clinicopathologic characteristics of patients with operable gallbladder cancer (GBCA), intrahepatic bile duct cancer (IHBDC), or extrahepatic bile duct cancer (EHBDC) were obtained from the Surveillance, Epidemiology and End Results (SEER) database (2004-2015). Univariate and multivariate analyses were performed to identify prognostic factors for overall survival (OS). Selection bias were reduced by propensity-score matching (PSM). Kaplan-Meier analysis was used to estimate the survival time. RESULTS Within 922 patients, 53.9% received adjuvant CRT, and 46.1% received adjuvant CT. Multivariate analysis showed age, primary tumor site, T stage, N stage, tumor size, number of removed lymph nodes, and treatment were independent risk factors for OS. Similar improvement of CRT on survival was identified by PSM in the matched cohort compared with CT (28.0 months vs. 25.0 months, p = 0.033), particularly in GBCA cohort (25.0 months vs. 19.0 months, p = 0.003). Subgroup analysis indicated CRT improved outcomes of patients with age ≥ 60, female, lymph nodes positive, tumor size ≥ 5 cm, and none removed lymph node diseases. CONCLUSION Adjuvant CRT correlated with improved survival in patients with resected BTC compared with adjuvant CT, particularly in GBCAs. In addition, patients with age ≥ 60, female, lymph nodes positive, tumor size ≥ 5 cm, and none removed lymph node diseases may receive more benefits from adjuvant CRT.

Abstract
Cirrhosis is the end stage of chronic liver disease and causes architectural distortion and perfusional anomalies. It is a major risk factor for developing hepatocellular carcinoma (HCC). Common disease entities in noncirrhotic livers, such as hemangiomas, can be rare in cirrhotic livers, and benign entities such as confluent hepatic fibrosis and focal nodular hyperplasia-like lesions may mimic the appearance of malignancies,. HCC usually has typical imaging characteristics, such as the major features established by the Liver Imaging Reporting and Data System. However, HCC can also have a spectrum of atypical or uncommon appearances, such as cystic HCC, hypovascular HCC, or macroscopic fat-containing HCC. HCCs with certain genetic mutations such as CTNNB-1-mutated HCC can harbor unique imaging features not seen in other types of HCC. In addition, malignancies that are less common than HCC, such as cholangiocarcinoma and metastases, which can be difficult to differentiate, can still occur in cirrhotic livers. Atypical imaging features of benign and malignant lesions can be challenging to accurately diagnose. Therefore, familiarity with these features and an understanding of the prevalence of disease entities in cirrhotic livers are key in the daily practice of radiologists for evaluation of cirrhotic livers. The authors illustrate the typical and atypical features of benign and malignant lesions in cirrhosis and discuss the technical pitfalls and unique advantages associated with various imaging modalities in assessing cirrhotic livers, including noncontrast and contrast-enhanced US, CT, and MRI.

Abstract
BACKGROUND To investigate venous thromboembolism (VTE) in patients undergoing distal cholangiocarcinoma (dCCA) surgery, we performed a single-center study to assess its prevalence, risk factors, prognosis. METHOD We studied a total of 177 patients undergoing dCCA surgery from January 2017 to April 2022. Demographic, clinical data, laboratory data (including lower extremity ultrasound findings), and outcome variables were obtained, and compared between VTE and non-VTE groups. RESULTS Of the 177 patients undergoing dCCA surgery (aged 65.2 ± 9.6 years; 108 (61.0%) male), 64 patients developed VTE after surgery. Logistic multivariate analysis showed that, age, operation procedure, TNM stage, ventilator duration and preoperative D-dimer were independent risk factors. Based on these factors, we constructed the nomogram to predict VTE after dCCA for the first time. The areas under the receiver operating curve (ROC) of the nomogram were 0.80 (95% CI: 0.72-0.88) and 0.79 (95% CI: 0.73-0.89) in the training and validation groups, respectively. Patients developed VTE had a worse prognosis by Kaplan-Meier curve analysis (p = 0.001). CONCLUSION The prevalence of VTE is high and is associated with adverse outcomes in patients undergoing dCCA surgery. We developed a nomogram assessing VTE risk, which may help clinicians to screen out people at high risk for VTE and to undertake rational preventive measures.

Abstract
BACKGROUND Infiltrated margins of resection (R1) and lymph node invasion are dominant negative predictors of survival in patients with a resectable perihilar cholangiocarcinoma. Less clear is whether survival predictors stratify differently between R0 (tumor-free margins) and R1 patients and whether the prognosis of the latter patients is influenced by the pattern of neoplastic infiltration (ie, radial versus longitudinal infiltration). We retrospectively evaluated a series of reported resected perihilar cholangiocarcinoma to obtain insights on the predictive power of these histologic features. METHODS The study includes 264 patients with perihilar cholangiocarcinoma treated between 2004 and 2019 in our center and followed up for >18 months. There were 176 patients with R0 (66.6%) and 88 patients with R1 (33.3%), 31 with radial infiltration only, 30 with longitudinal infiltration only, and 27 with both infiltration patterns. In all patients, the criteria for resection was the absence of metastatic involvement (ie, distant organ metastases, liver metastases, and lymph node metastases beyond the hepatoduodenal ligament). Histopathologic specimens of the resected tumors were centrally reviewed by a pathologist unaware of the clinical outcomes. RESULTS Three- and 5-year long-term survival were significantly better in R0 (respectively) compared to R1 patients (55% and 42% vs 42% and 18%, respectively, P < .05). In R1 patients with radial infiltration only and those with radial + longitudinal infiltration, both disease-free and overall survival were worse than those with longitudinal infiltration only (median disease-free survival of 18 and 23 months, respectively, P < .05, median overall survival of 33 and 39 months, respectively, P < .05). At multivariable analysis, nodal status, side of hepatectomy, grading, and presence of radial margin infiltration were associated with long-term outcome. CONCLUSION Radial infiltration of resection margins enhances the negative prognostic value of R1 margins in perihilar cholangiocarcinoma patients and should specifically be accounted for in the prediction of the outcome of adjuvant therapy.

Abstract
Comprehensive analysis of the expression and probable function of LSM2 in Live hepatocellular carcinoma (LIHC), and validation via in vitro experiments. Integrated use of database resources to examine the differential expression, survival prognosis, clinicopathological characteristics, and functional enrichment of LSM2 in LIHC. The expression level of LSM2 in LIHC tissues and adjacent tissues was proven via immunohistochemical staining. The biological function of LSM2 in LIHC was detected by cell proliferation, cell cloning, cell scratch, cell migration, and invasion experiments in vitro. TIMER 2.0 and GEPIA indicated that LSM2 was highly expressed in cancers and was strongly associated with survival rates in LIHC, cholangiocarcinoma, breast cancer, and renal clear cell carcinoma. LSM2 was highly expressed in LIHC, which was closely associated to the clinicopathological characteristics of patients, and the overall survival rate and disease-free survival rate of patients with high expression of LSM2 were lower than those with low expression of LSM2. Functional enrichment results revealed that LSM2 was involved to ribosome formation, DNA replication, cell cycle, metabolic processes, JAK-STAT signaling pathways, and FoxO signaling pathways. Knockdown of LSM2 inhibited the proliferation, migration, and invasion of LIHC cells in vitro experiments. LSM2 was highly expressed in LIHC and was related to a poor prognosis. Knockdown of LSM2 could inhibit the proliferation, migration, and invasion of LIHC cells.

Abstract
Intrahepatic cholangiocarcinoma (ICC) is one of the most common invasive malignant tumors, with a 5-year survival rate of less than 5%. Currently, radical surgical resection is the preferred treatment for ICC. However, most patients are only diagnosed at an advanced stage and are therefore not eligible for surgery. Herein, we present a case of advanced ICC in which radical surgery was not possible due to tumor invasion of the second porta hepatis and right hepatic artery. Six treatment cycles with a gemcitabine and oxaliplatin (GEMOX) regimen combined with camrelizumab immunotherapy achieved a partial response and successful tumor conversion, as tumor invasion of the second porta hepatis and right hepatic artery was no longer evident. The patient subsequently underwent successful radical surgical resection, including hepatectomy, caudate lobe resection, and cholecystectomy combined with lymph node dissection. Cases of patients with advanced ICC undergoing surgical resection after combined immunotherapy and chemotherapy are rare. The GEMOX regimen combined with camrelizumab demonstrated favorable antitumor efficacy and safety, suggesting that it might be a potential feasible and safe conversion therapy strategy for patients with advanced ICC.

Lacking Immunotherapy Biomarkers for Biliary Tract Cancer: A Comprehensive Systematic Literature Review and Meta-Analysis. Cells 2023; 12:2098. [PMID: 37626908 PMCID: PMC10453268 DOI: 10.3390/cells12162098] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 08/06/2023] [Accepted: 08/14/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND Immunotherapy has recently been incorporated into the spectrum of biliary tract cancer (BTC) treatment. The identification of predictive response biomarkers is essential in order to identify those patients who may benefit most from this novel treatment option. Here, we propose a systematic literature review and a meta-analysis of PD-1, PD-L1, and other immune-related biomarker expression levels in patients with BTC. METHODS Prisma guidelines were followed for this systematic review and meta-analysis. Eligible studies were searched on PubMed. Studies published between 2017 and 2022, reporting data on PD-1/PD-L1 expression and other immune-related biomarkers in patients with BTC, were considered eligible. RESULTS A total of 61 eligible studies were identified. Despite the great heterogeneity between 39 studies reporting data on PD-L1 expression, we found a mean PD-L1 expression percentage (by choosing the lowest cut-off per study) of 25.6% (95% CI 21.0 to 30.3) in BTCs. The mean expression percentages of PD-L1 were 27.3%, 21.3%, and 27.4% in intrahepatic cholangiocarcinomas (iCCAs-15 studies), perihilar-distal CCAs (p/dCCAs-7 studies), and gallbladder cancer (GBC-5 studies), respectively. Furthermore, 4.6% (95% CI 2.38 to 6.97) and 2.5% (95% CI 1.75 to 3.34) of BTCs could be classified as TMB-H and MSI/MMRd tumors, respectively. CONCLUSION From our analysis, PD-L1 expression was found to occur approximately in 26% of BTC patients, with minimal differences based on anatomical location. TMB-H and MSI molecular phenotypes occurred less frequently. We still lack a reliable biomarker, especially in patients with mismatch-proficient tumors, and we must need to make an effort to conceive new prospective biomarker discovery studies.

Abstract
Studies investigating the potential role of circulating bile acids (BAs) as diagnostic biomarkers for cholangiocarcinoma (CCA) are sparse and existing data do not adjust for confounding variables. Furthermore, the mechanism by which BAs affect the expression of the oncogenic mucin 5AC (MUC5AC) has never been investigated. We performed a case-control study to characterise the profile of circulating BAs in patients with CCA (n = 68) and benign biliary disease (BBD, n = 48) with a validated liquid chromatography-tandem mass spectrometry technique. Odd ratios (OR) for CCA associations were calculated with multivariable logistic regression models based on a directed acyclic graph structure learning algorithm. The most promising BAs were then tested in an in vitro study to investigate their interplay in modulating MUC5AC expression. The total concentration of BAs was markedly higher in patients with CCA compared with BBD controls and accompanied by a shift in BAs profile toward a higher proportion of primary conjugated BAs (OR = 1.50, CI: 1.14 to 1.96, p = 0.003), especially taurochenodeoxycholic acid (TCDCA, OR = 42.29, CI: 3.54 to 504.63, p = 0.003) after multiple adjustments. Western blot analysis of secreted MUC5AC in human primary cholangiocytes treated with primary conjugated BAs or with TCDCA alone allowed us to identify a novel 230 kDa isoform, possibly representing a post-translationally modified MUC5AC specie.

Abstract
Accumulation of fibroblasts in the premalignant or malignant liver is a characteristic feature of liver cancer, but has not been therapeutically leveraged despite evidence for pathophysiologically relevant roles in tumour growth. Hepatocellular carcinoma is a largely non-desmoplastic tumour, in which fibroblasts accumulate predominantly in the pre-neoplastic fibrotic liver and regulate the risk for hepatocellular carcinoma development through a balance of tumour-suppressive and tumour-promoting mediators. By contrast, cholangiocarcinoma is desmoplastic, with cancer-associated fibroblasts contributing to tumour growth. Accordingly, restoring the balance from tumour-promoting to tumour-suppressive fibroblasts and mediators might represent a strategy for hepatocellular carcinoma prevention, whereas in cholangiocarcinoma, fibroblasts and their mediators could be leveraged for tumour treatment. Importantly, fibroblast mediators regulating hepatocellular carcinoma development might exert opposite effects on cholangiocarcinoma growth. This Review translates the improved understanding of tumour-specific, location-specific, and stage-specific roles of fibroblasts and their mediators in liver cancer into novel and rational therapeutic concepts.

Abstract
A 55-year-old female patient with a history of ethyl and nicotine abuse presented with chronic diarrhoea, significant weight loss and abnormal liver tests. Ultrasound examination revealed dilatation of the bile ducts and computed tomography scan with IV contrast further established simultaneous dilatation of the common bile duct and pancreatic duct (double duct sign). The dilatation abruptly stopped at the level of the pancreatic head which demonstrated a small irregular hypovascular zone (1.2 cm), suspected for malignancy. The following week, a radical pancreaticoduodenectomy was performed. Anatomopathological analysis revealed an adenomyoma (12 mm) located distal to the common bile duct, without arguments for malignancy.

Abstract
BACKGROUND Biliary cystic neoplasms (BCNs) of the liver are rare pathologies encountered in hepatobiliary surgeries. Till now, there is a lack of definitive criteria used to differentiate biliary cystadenoma (BCA) from biliary cystadenocarcinoma (BCAC). METHODS In the period between 2005 and 2018, the data of consecutive patients diagnosed with BCA and BCAC were retrospectively reviewed. RESULTS A total of 62 patients underwent surgical management for BCNs. BCA was diagnosed in 50 patients while 12 patients had BCAC. Old age, male gender, smoking, and abdominal pain were strongly associated with BCAC. Left lobe location, small size, with the presence of mural nodule, and solid component were significantly noticed with BCAC. A novel pre-operative score was developed to predict the susceptibility for BCAC and help us to identify the optimal surgical strategy. Blood loss, operative time, and complications were comparable between the two study groups. CONCLUSION Mural nodules or solid components are suggestive of BCAC. Complete surgical resection of cystic tumors of the liver is mandatory due to malignant potential of the lesion and for prolonged survival.

Abstract
Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by fibroinflammatory damage to the biliary tree, typically in the setting of inflammatory bowel disease, with an increased risk of liver failure and cholangiocarcinoma. A complex pathophysiology, heterogeneity in clinical features, and the rare nature of the disease have contributed to the lack of effective therapy to date. However, recent innovations in the characterization and prognostication of patients with PSC, in addition to new tools for medical management and emerging pharmacologic agents, give rise to the potential for meaningful progress in the next several years. This review summarizes current concepts in PSC and highlights particular areas in need of further study.

Abstract
BACKGROUND The Italian Register of Actionable Mutations (RATIONAL) is a multicentric, observational study collecting next-generation sequencing (NGS)-based tumour profiling data of patients with advanced solid tumours. METHODS The study enrols patients who had available an NGS-based tumour profiling (Pathway-A) or undergo comprehensive genomic profiling (CGP) with FoundationOne CDx assays within the trial (Pathway-B). The primary endpoint was the rate of actionable mutations identified. RESULTS Sequencing data were available for 738 patients in Pathway-A (218) and -B (520). In Pathway-A, 154/218 (70.6%) tests were performed using NGS panels ≤52 genes, and genomic alterations (GAs) were found in 164/218 (75.2%) patients. In Pathway-B, CGP revealed GAs in 512/520 (98.5%) patients. Levels I/II/III actionable GAs according to the European Society of Medical Oncology Scale for Clinical Actionability of molecular Targets (ESCAT) were identified in 254/554 (45.8%) patients with non-small-cell lung cancer, cholangiocarcinoma, colorectal, gastric, pancreatic and breast cancer. The rate of patients with level I GAs was similar in Pathways A and B (69 versus 102). CGP in Pathway-B revealed a higher number of patients with level II/III GAs (99 versus 20) and potentially germline pathogenic/likely pathogenic variants (58 versus 15) as compared with standard testing in Pathway-A. In patients with cancer of unknown primary, CGP detected OncoKB levels 3B/4 GAs in 31/58 (53.4%) cases. Overall, 67/573 (11.7%) of patients received targeted therapy based on genomic testing. CONCLUSION The Italian Register of Actionable Mutations represents the first overview of genomic profiling in Italian current clinical practice and highlights the utility of CGP for identifying therapeutic targets in selected cancer patients.

Abstract
INTRODUCTION AND AIM Preliminary studies showed good expression of fibroblast activating protein inhibitor (FAPI) in hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). Our aims were to study the diagnostic performance of 68 Ga-FAPI PET/CT in diagnosing the primary hepatobiliary malignancies and to compare its performance with 18 F-FDG PET/CT. PATIENTS AND METHODS Patients suspected to have HCC and CC were recruited prospectively. FDG and FAPI PET/CT studies were completed within 1 week. Final diagnosis of malignancy was achieved by tissue diagnosis (either histopathological examination or fine-needle aspiration cytology) and radiological correlation from conventional modalities. Results were compared with final diagnosis and expressed as sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy. RESULTS Forty-one patients were included. Thirty-one were positive for malignancy and 10 were negative. Fifteen were metastatic. Of 31, 18 were CC and 6 were HCC. For overall diagnosis of the primary disease, FAPI PET/CT performed exceptionally compared with FDG PET/CT with sensitivity, specificity, and accuracy of 96.77%, 90%, and 95.12%, respectively, versus 51.61%, 100%, and 63.41% for FDG PET/CT. FAPI PET/CT clearly outperformed FDG PET/CT for the evaluation of CC with sensitivity, specificity, and accuracy of 94.4%, 100%, and 95.24%, respectively, whereas for FDG PET/CT sensitivity, specificity, and accuracy were 50%, 100%, and 57.14%, respectively. Diagnostic accuracy of FAPI PET/CT was 61.54% for metastatic HCC compared with 84.62% for FDG PET/CT. CONCLUSIONS Our study highlights the potential role of FAPI-PET/CT in evaluating CC. It also ascertains its usefulness in the cases of mucinous adenocarcinoma. Although it showed a higher lesion detection rate than FDG in primary HCC, its diagnostic performance in the metastatic setting is questionable.
