The state of therapy modalities in clinic for biliary tract cancer.

Front Biosci (Landmark Ed) 2022 Jun;27(6):185

Hepatic Surgery Centre, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, 430030 Wuhan, Hubei, China.

Biliary tract cancers (BTCs) include intrahepatic cholangiocarcinoma (iCCA), perihilar and distal cholangiocarcinoma (pCCA and dCCA), and gallbladder carcinoma based on the epithelial site of origin. BTCs are highly aggressive tumors associated with poor prognosis due to widespread metastasis and high recurrence. Surgery is the typical curative-intent treatment, yet the cornerstone of cure depends on the anatomical site of the primary tumor, and only a minority of patients (approximately 30%) has an indication necessitating surgery.

Role of ERCP in Malignant Hilar Biliary Obstruction.

Gastrointest Endosc Clin N Am 2022 Jul 11;32(3):427-453. Epub 2022 May 11.

Department of Medicine, Division of Gastroenterology/Hepatology, Indiana University School of Medicine, Indiana University Health-University Hospital, 550 North University Boulevard, Suite 1634, Indianapolis, IN 46202, USA.

Malignant hilar biliary obstruction (MHO), an aggressive perihilar biliary obstruction caused by cholangiocarcinoma, gallbladder cancer, or other metastatic malignancies, has a poor prognosis. Surgical resection is the only curative treatment method for biliary malignancies. However, most of the patients with MHO cannot undergo surgeries on presentation because of an advanced inoperable state or a poor performance state due to old age or comorbid diseases. Read More

Morbidity analysis of left hepatic trisectionectomy for hepatobiliary disease and live donor.

Hepatobiliary Pancreat Dis Int 2022 May 24. Epub 2022 May 24.

Department of Surgery, Gold Coast University Hospital, Southport, QLD 4215, Australia.

Background: Despite remarkable advances in surgical techniques and perioperative management, left hepatic trisectionectomy (LHT) remains a challenging procedure with a somewhat high postoperative morbidity rate compared with less-extensive resections. This study aimed to analyze the short- and long-term outcomes of LHT and identify factors associated with the postoperative morbidity of this technically demanding surgical procedure.

Clinical, Genomic, and Transcriptomic Data Profiling of Biliary Tract Cancer Reveals Subtype-Specific Immune Signatures.

JCO Precis Oncol 2022 Jun;6:e2100510

Johns Hopkins University, Baltimore, MD.

Purpose: Biliary tract cancers (BTCs) are aggressive cancers that carry a poor prognosis. An enhanced understanding of the immune landscape of anatomically and molecularly defined subsets of BTC may improve patient selection for immunotherapy and inform immune-based combination treatment strategies.

Methods: We analyzed deidentified clinical, genomic, and transcriptomic data from the Tempus database to determine the mutational frequency and mutational clustering across the three major BTC subtypes (intrahepatic cholangiocarcinoma [IHC], extrahepatic cholangiocarcinoma, and gallbladder cancer).

Incidental gallbladder cancer diagnosis confers survival advantage irrespective of tumour stage and characteristics.

World J Gastroenterol 2022 May;28(18):1996-2007

Department of HPB and Liver Transplantation, Queen Elizabeth Hospital, University Hospitals Birmingham, Birmingham B15 2TH, United Kingdom.

Background: Incidental gallbladder cancer (IGBC) represents 50%-60% of gallbladder cancer cases. Data are conflicting on the role of IGBC diagnosis in oncological outcomes. Some studies suggest that IGBC diagnosis does not affect outcomes, while others that overall survival (OS) is longer in these cases compared to non-incidental diagnosis (NIGBC). Read More

Case reports: chemoradiotherapy for locally advanced neuroendocrine carcinoma of the gallbladder.

Clin J Gastroenterol 2022 Jun 2. Epub 2022 Jun 2.

Department of Oncology, Yokohama City University School of Medicine Graduate School of Medicine, Yokohama, Japan.

Neuroendocrine carcinoma (NEC) is a rare subtype of malignant gallbladder tumor. Although surgical resection is the only potentially curative therapy for gallbladder NEC, most cases are surgically unresectable because of advanced stage disease and/or biologically aggressive behavior. The standard palliative treatment for malignant gallbladder tumors is chemotherapy; however, the efficacy of chemoradiotherapy in the treatment of gallbladder tumors is controversial. Read More

Polypoid-Type Adenomyomatous Lesion of the Cystic Duct: Report of a Case and Review of Literature.

Int J Surg Pathol 2022 May 29:10668969221102545. Epub 2022 May 29.

Department of Pathology, Japan Self-Defense Forces Central Hospital, Tokyo, Japan.

Adenomyomatous hyperplasia, a common non-neoplastic lesion in the gallbladder, is rarely identified in the extrahepatic bile duct. Typically, these lesions appear as a nodule or mural thickening/elevation. However, in exceptional circumstances, pedunculated/polypoid adenomyomatous lesion occurs in the biliary tract; two cases in the gallbladder and only one case in the common bile duct have been reported.

Hua Han Jun Han

Contrast Media Mol Imaging 2022 6;2022:5459779. Epub 2022 May 6.

Department of Radiology, The Third Affiliated Hospital of Chongqing Medical University, Chongqing 401120, China.

To summarize the value of multislice spiral CT (MSCT) in the differential diagnosis of thick-wall gallbladder carcinoma (TWGC) and chronic cholecystitis (CC), the clinical data of 36 patients with TWGC and 60 patients with chronic cholecystitis who were treated in our hospital from January 2017 to May 2021 were retrospectively analyzed, and the CT image features and diagnostic accuracy of the patients were summarized. Compared with the CC group, the proportions of disruption of gallbladder mucosa line, blurred gallbladder outline, high obstruction of biliary tract, lymphomegaly, adjacent invasion, peritoneal effusion, wall nodules, and the gallbladder wall thickness in the TWGC group were higher, with statistical significance ( < 0.05).

Is the tumor-stroma ratio a prognostic factor in gallbladder cancer?

Rev Assoc Med Bras (1992) 2022 May;68(5):664-669

University of Health Sciences Turkey, Haydarpasa Numune Training and Research Hospital, Department of General Surgery - Istanbul, Turkey.

Objective: This study aimed to examine the prognostic effect of the tumor-stroma ratio, which has been shown to have prognostic value in various cancers, in patients with gallbladder cancer who have undergone curative resection.

Methods: The records of gallbladder cancer patients who underwent surgical treatment in our clinic between December 2005 and March 2021 were analyzed retrospectively. The hematoxylin and eosin-stained sections representing the tumors were evaluated under light microscopy to determine tumor-stroma ratio, and based on the results, <50% was defined as the stroma-rich and ≥50% as the stroma-poor groups.

The cytokeratin 17 expression in primary ovarian tumors has diagnostic but not prognostic significance.

Virchows Arch 2022 May 13. Epub 2022 May 13.

Institute of Pathology, First Faculty of Medicine, Charles University and General University Hospital in Prague, Studničkova 2, 12800, Prague 2, Czech Republic.

We assessed the value of cytokeratin 17 (CK17) expression for the differential diagnosis between primary ovarian mucinous tumors and metastases from the gastrointestinal tract (GIT) and the significance of CK17 expression in a broad spectrum of primary ovarian tumors with respect to their prognosis. The sample set consisted of 554 primary ovarian tumors and 255 GIT tumors. In the primary ovarian tumors, a higher CK17 expression (in > 10% of tumors cells) was present only in 0-11. Read More

Gallbladder Neuroendocrine Tumors: Is There a Need for a Specific Approach?

Gastrointest Tumors 2022 Mar 18;9(1):5-11. Epub 2021 Nov 18.

Department of Surgical Gastroenterology & HPB Surgery, Jaslok Hospital and Research Centre, Mumbai, India.

Neuroendocrine tumors (NETs) of the gallbladder or the biliary tree are rare. Most of the current guidelines and protocols are derived from the experience of managing lung small cell neuroendocrine carcinoma or gastrointestinal NETs. But, the overall outcome of gallbladder NETs (GB-NETs) seems worse than similarly staged lung NETs and adenocarcinoma of the gallbladder. Read More
