Abstract Background Previous studies report increasing cholangiocarcinoma (CCA) incidence up to 2015. This contemporary retrospective analysis of CCA and mortality in the US from 2001-2017 assessed whether continued increase beyond Patients Methods (≥18 years) with were identified National Cancer Institute Surveillance, Epidemiology, End Results 18 cancer registry (International Classification Disease for Oncology [ICD-O]-3 codes: intrahepatic [iCCA], C221; extrahepatic [eCCA], C240, C241, C249). unknown primary (CUP) cases (ICD-O-3: C809; 8140/2, 8140/3, 8141/3, 8143/3, 8147/3) because potential misclassification as iCCA. Forty-thousand-and-thirty (iCCA, n=13,174; eCCA, n=26,821; iCCA n=35) 32,980 CUP analyzed. From 2001-2017, CCA, iCCA, eCCA (per 100 000 person-years) increased 43.8% (3.08 4.43), 148.8% (0.80 1.99), 7.5% (2.28 2.45), respectively. In contrast, decreased 54.4% (4.65 2.12). age, greatest among younger patients (18-44 years, 81.0%). Median overall survival diagnosis was 8, 6, 9, 2 months CUP. 2001-2016, annual rate declined (57.1% 41.2%) generally remained stable (40.9% 37.0%) (64.3% 68.6%). Conclusions greater versus whereas decreased. The divergent trends, absolute change incidence, provide evidence a true that may not be wholly attributable reclassification.

Abstract Long noncoding RNAs (lncRNAs) are a novel class of that have emerged as critical regulators and biomarkers in various cancers. Nevertheless, the expression profile mechanistic function lncRNAs cholangiocarcinoma (CCA) remain unclear. Herein, we examined levels linc00976 clinical specimens cell lines using reverse transcription-quantitative PCR. In total, 50 patients with CCA were enrolled to analyze correlation between characteristics CCA.

Cholangiocarcinomas (CCA) are a heterogeneous group of tumors that classified as intrahepatic, perihilar, or distal according to the anatomic location within biliary tract. Each CCA subtype is associated with distinct genomic alterations, including single nucleotide variants, copy number and chromosomal rearrangements gene fusions, each which can influence disease prognosis and/or treatment outcomes. Molecular profiling using next-generation sequencing (NGS) powerful technique for identifying unique variants carried by an individual tumor, facilitate their accurate diagnosis well promote optimal selection variant–matched targeted treatments. NGS particularly useful in patients because between one-third one-half these have alterations be drugs either approved clinical development. also provide information about evolution secondary resistance develop during therapy, thus assessment choice alternative Pathologists play critical role assessing viability biopsy samples NGS, advising treating clinicians whether performed available platforms should used optimize testing This review aims pathologists other healthcare professionals practical step-by-step guidance on use molecular CCA, respect tumor techniques, pre-analytic sample preparation, selecting appropriate panel, understanding interpreting results test.

Cholangiocarcinomas (CCAs) are aggressive tumors arising along the biliary tract epithelium, whose incidence and mortality increasing. CCAs highly desmoplastic cancers characterized by a dense tumor microenvironment (TME), in which each single component plays fundamental role shaping CCA initiation, progression resistance to therapies. The crosstalk between cancer cells TME can affect recruitment, infiltration differentiation of immune cells. According stage disease intra- inter-patient heterogeneity, may contribute either protumoral or antitumoral activities. Therefore, better understanding effect cell subtype open path new personalized therapeutic strategies for management CCA.

Abstract Background Increasing evidence shows that circular RNAs (circRNAs), a novel class of noncoding RNAs, play crucial role in the development cancers, including intrahepatic cholangiocarcinoma (iCCA). Nevertheless, their functions and exact mechanisms iCCA progression metastasis are still unclear. Ipatasertib is highly selective inhibitor AKT inhibits tumor growth by blocking PI3K/AKT pathway. In addition, phosphatase tensin homolog (PTEN) can also inhibit activation pathway, but it not clear whether cZNF215-PRDX-PTEN axis plays antitumor activity ipatasertib. Methods We identified new circRNA (circZNF215, termed cZNF215) through high-throughput sequencing (circRNA-seq). RT‒qPCR, immunoblot assay, RNA pull-down immunoprecipitation (RIP) fluorescence situ hybridization assay (FISH) were used to investigate interaction cZNF215 with peroxiredoxin 1 (PRDX1). Coimmunoprecipitation (Co-IP) assays duolink proximity ligation (PLAs) conducted analyze effects on between PRDX1 PTEN. Finally, we tested potential ipatasertib vivo experiments. Results found expression was obviously upregulated tissues postoperative metastases correlated poor outcome patients iCCA. further revealed overexpression promoted cell vitro vivo, while knockdown had opposite effect. Mechanistic studies suggested competitively interacted PRDX1, which blocked association PTEN, subsequently leading oxidation-induced inactivation PTEN/AKT pathway finally contributing metastasis. Additionally, silencing cells enhance effect Conclusions Our study demonstrates facilitates regulating may serve as prognostic predictor

Cholangiocarcinomas are a heterogeneous group of highly aggressive cancers that may arise anywhere within the biliary tree. There is wide geographical variation with regards to its incidence, and risk-factor associations which include liver fluke infection, primary sclerosing cholangitis, hepatolithiasis amongst others. These tumours classified into intrahepatic, perihilar distal based on their anatomical location. Morphologically, intrahepatic cholangiocarcinomas further sub-classified small large duct variants. Perihilar usually mucin-producing tubular adenocarcinomas. develop through multistep carcinogenesis preceded by dysplastic in situ lesions. While clinical characteristics management these have been extensively elucidated literature, ultra-structure tumour biology remain relatively unknown. This review focuses current knowledge pathological characteristics, molecular alterations cholangiocarcinoma, precursor lesions (including intraepithelial neoplasia, intraductal papillary neoplasms bile duct, tubulopapillary mucinous cystic neoplasm).
