Establishment of Patient-Derived Organoids and Drug Screening for Biliary Tract Carcinoma

Publication date: 23 April 2019Source: Cell Reports, Volume 27, Issue 4Author(s): Yoshimasa Saito, Toshihide Muramatsu, Yae Kanai, Hidenori Ojima, Aoi Sukeda, Nobuyoshi Hiraoka, Eri Arai, Yuko Sugiyama, Juntaro Matsuzaki, Ryoei Uchida, Nao Yoshikawa, Ryo Furukawa, Hidetsugu SaitoSummaryBiliary tract carcinomas (BTCs) are among the most aggressive malignancies and have a poor prognosis. Here, we successfully established organoid lines derived from intrahepatic cholangiocarcinoma, gallbladder cancer, and neuroendocrine carcinoma of the ampulla of Vater. These organoids derived from BTCs were cultured stably for>1 year and closely recapitulated the histopathology, gene expression, and genetic alterations evident in the primary tumors. Gene expression profiling of the organoids revealed that SOX2 could be a potential prognostic biomarker for patients with BTC. We screened a compound library consisting of drugs used clinically for their ability to suppress organoids derived from BTCs and found that the antifungal drugs amorolfine and fenticonazole significantly suppressed the growth of organoids derived from BTCs with minimal toxicity to normal biliary epithelial cells. Patient-derived organoids may be a powerful research tool for the clarification of molecular pathogenesis and the discovery of biomarkers and therapeutic drugs for refractory cancers.Graphical Abstract

Elsheikh, Yaxia ZhangBackfroundPolyoma virus cytopathic effect (BK-CPE) is classified as “Negative for high-grade urothelial carcinoma (NHGUC)” in the Paris System for Reporting Urinary Cytology (TPS). However, polyomaviruses have been historically associated with tumor development and recently reported as an independent risk factor for renourinary carcinoma in transplant patients. The aim of this study was to investigate the relationship between polyomavirus infection in the ...

Authors: Lancellotti P, De Pauw M, Claeys M Abstract Cardiovascular disease (CVD) and cancer represent the two main causes of death in industrialised countries. Both share common risk factors (diabetes, obesity, hypertension, diet, smoking, etc.). The associated timing of CVD and cancer onset is thus largely influenced by modifiable risk factors. Advances in cancer treatment have extended the lives of patients with cancer, but for some at the cost of adverse cardiovascular events. The rapidly growing number of patients surviving cancer, often in the setting of advanced age, new or pre-existing CV disease and risk f...

Authors: Lai G, Guo N, Jiang Y, Lai J, Li Y, Lai R Abstract OBJECTIVE: To assess whether the duration of one-lung ventilation (OLV) affects postoperative pulmonary complications after McKeown esophagectomy for esophageal cancer. METHODS: A retrospective analysis of data stored in a database for esophageal cancer was carried out to identify predictors of postoperative pulmonary complications in patients undergoing McKeown esophagectomy at Sun Yat-sen University Cancer Center between 2010 and 2012. RESULTS: Patients in the OLV ⩾150 minutes group had a higher incidence of postoperative pulmonary complication...

Authors: Wang XQ, Zheng Y, Fang PF, Song XB Abstract The lack of reliable plasma biomarkers limits their use in the diagnosis of gastric cancer (GC). The current study aimed to determine whether plasma nesfatin-1 can be used as a novel non-invasive biomarker for the diagnosis of GC. The levels of nesfatin-1 in 40 patients with GC and 40 healthy individuals, who were selected from the Chaohu Hospital Affiliated to Anhui Medical University, were assessed. ELISA was used for the measurement of plasma nesfatin-1 levels, while immunohistochemistry was applied to determine Ki67 protein expression in GC and normal gastric...

Authors: Ren L, Li Y, Zhao Q, Fan L, Tan B, Zang A, Yang H Abstract Breast cancer is one of the most prevalent types of cancer among women that leads to millions of deaths worldwide every year. The mechanisms of breast cancer pathogenesis remain unclear. It has been reported that aberrant expression of miR-519, is associated with breast cancer development; however, the effects of miR-519 on breast cancer cell proliferation remain unknown. Therefore, the present study aimed to determine whether miR-519 could regulate breast cancer cell proliferation. A total of 20 pairs of primary breast cancer and adjacent normal t...

AbstractThe biliary tract cancer (BTC) covers a range of carcinomas, including intrahepatic cholangiocarcinoma (ICC), cholangiolocellular carcinoma (CoCC), perihilar cholangiocarcinoma (perihilar CC), extrahepatic cholangiocarcinoma (ECC), and gallbladder cancer (GBC), defined according to the anatomical location. These adenocarcinomas mostly comprise biliary epithelial cell-derived malignant cells. In addition to anatomical differences, there are morphological and biological differences in BTC starting from embryonic development of the tissues extending to physiological differences. Fatty acid-binding proteins (FABPs) are...

Abstract Human epidermal growth factor receptor 2 (HER2) amplification/overexpression is an effective therapeutic target in breast and gastric cancer. Although HER2 positivity has been reported in other malignancies, previous studies generally focused on one cancer type, making it challenging to compare HER2 positivity across studies/malignancies. Herein, we examined 37,992 patient samples for HER2 expression (+/− amplification) in a single laboratory. All 37,992 patients were tested by immunohistochemistry (IHC); 21,642 of them were also examined for HER2 amplification with either fluorescent in situ hybrid...
