Gall bladder cancer

Gallbladder perforation is an uncommon occurrence that demands prompt surgical intervention, typically observed in the context of acute cholecystitis. In this article, we present an extraordinary case of gallbladder gangrene and perforation, originating from metastasis of colon cancer. The patient's presentation included an incidental discovery of colon cancer, which was indicated by histopathology of the gall bladder. This case report aims to shed light on the intricate relationship between gallbladder pathology and metastatic colon cancer, emphasizing the need for vigilant evaluation and comprehensive management strategies...

INTRODUCTION: The development of new autoantigen discovery techniques, like programmable phage immunoprecipitation sequencing (PhIP-Seq), has accelerated the discovery of neural-specific autoantibodies. Herein, we report the identification of a novel biomarker for paraneoplastic neurologic syndrome (PNS), Sloan-Kettering-Virus-Family-Transcriptional-Corepressor-2 (SKOR2)-IgG, utilizing PhIP-Seq. We have also performed a thorough clinical validation using normal, healthy, and disease/cancer control samples...

PURPOSE: The present study aimed to determine whether concomitant extrahepatic bile duct resection (EHBDR) improves the prognosis of patients with T2 gallbladder cancer (GBC). METHODS: Between 2014 and 2018, 4947 patients with GBC were registered in the National Biliary Tract Cancer Registry in Japan. This included 3804 patients (76.9%) who underwent curative-intent surgical resection; 1609 of these patients had pT2 GBC with no distant metastasis. Of the 1609 patients with GBC, 520 underwent EHBDR and 1089 did not...

BACKGROUND: Females having a large proportion of gallbladder carcinoma (GBC) and a higher incidence of gallstones pointed toward the role of sex hormones in GBC development. In this study, we evaluated the expression of Estrogen receptor (ER), Progesterone receptor (PR), and Her2/neu and their correlation with tumor markers and clinicopathological parameters in the GBC. METHODS: A total of 50 patients of GBC and 42 patients in control group undergoing surgery for other conditions were taken...

PURPOSE/OBJECTIVE(S): We intended to assess the patterns of care and failure in patients with solitary plasmacytoma (SP), treated at our institute from 2011-21. MATERIALS/METHODS: Data pertaining to the management of patients with SP was abstracted by retrospective chart review. Progression free survival (PFS) and overall survival (OS) were defined as the time intervals from the date of diagnosis to the date of progression (local, systemic or both) and death or last follow up, respectively...

Cell surface HLA-I molecules (Face-1) consist of a polypeptide heavy chain (HC) with two groove domains (G domain) and one constant domain (C-domain) as well as a light chain, B2-microglobulin (B2m). However, HCs can also independently emerge unfolded on the cell surface without peptides as B2m-free HC monomers (Face-2), B2m-free HC homodimers (Face 3), and B2m-free HC heterodimers (Face-4). The transport of these HLA variants from ER to the cell surface was confirmed by antiviral antibiotics that arrest the release of newly synthesized proteins from the ER...

BACKGROUNDS/AIMS: To study histopathological changes in gall bladder mucosa in cholelithiasis patients, and analyse their relation to the number and size of gallstones. These findings were evaluated in the context of age distribution of the study population. METHODS: One hundred cases of cholecystectomy were part of the study, which was conducted in collaboration with the pathology department. The time period of the study was January 2020 to June 2021. RESULTS: Maximum cases had multiple stones (69...

This case report describes an unusual paraneoplastic leukemoid response presenting in a rare instance of gallbladder (GB) adenosquamous carcinoma (ASC). Adenocarcinoma is the most prevalent histological subtype of GB carcinoma, which is most frequently diagnosed in people in their sixth and seventh decades of life. Adenosquamous and squamous variations are uncommon. Rarely have reports of paraneoplastic leukemoid reaction (PLR) in GB carcinoma been made; this reaction is characterized by a white cell count exceeding 50,000/mm3  in combination with solid malignancy...

The biliary tract's most frequent malignancy is gallbladder cancer (GBC). Due to the growing number of laparoscopic cholecystectomy procedures, the majority of GBC cases in the United States are diagnosed as incidental findings. Roughly 5% of the reported cases of gallbladder adenocarcinomas are of the mucinous type. Mucinous adenocarcinoma tumors contain more than 50% of mucin materials and are clinically characterized by poor prognosis. Initial presentation can mimic acute cholecystitis or cholelithiasis; meanwhile, histological findings post-cholecystectomy are the main diagnostic criteria of mucinous adenocarcinoma of the gallbladder...

Extracellular vesicles (EVs), which are heterogeneous membrane-based vesicles with bilayer cell membrane structures, could be versatile biomarkers for the identification of diverse diseases including cancers. With this potential, this study has attempted the Raman spectroscopic identification of gall bladder (GB) cancer by directly measuring the EV solution extracted from human bile without further sample drying. For this purpose, bile samples were obtained from four normal individuals and 21 GB polyp, eight hepatocellular carcinoma (HCC), and five GB cancer patients, and EVs were extracted from each of the bile samples...

Gallbladder cancer (GBC) is characterized by a highly invasive nature and a poor prognosis, with adenocarcinoma being the main histological subtype. According to statistical data, patients diagnosed with advanced GBC have a survival rate of less than 5% for 5 years. Despite the novel therapeutic techniques, the unsatisfactory results could be related to the underlying biology of tumor cells and resistance to chemotherapy. Early diagnosis is more important than clinical therapy as it assists in determining the pathological stage of cancer and facilitates the selection of appropriate medication...

Cowden syndrome is an uncommon autosomal dominant disorder characterized by multiple hamartomas in various tissues. It is associated with germline mutation in the phosphatase and tensin homolog (PTEN) gene. It has an increased risk of malignancies of various organs (commonly breast, thyroid, and endometrium) and benign overgrowth of tissues like skin, colon, and thyroid. Here, we present a case of Cowden syndrome in a middle-aged female who presented with acute cholecystitis with gall bladder polyps along with intestinal polyps...

BACKGROUND: Revision surgery (RS) is the standard of care for gallbladder cancer (GBC) after simple cholecystectomy (SC). Often these patients are unsuitable for RS due to late referral or unresectable disease. Do such patients benefit with chemotherapy (CT) alone or dual-modality (CT followed by consolidation chemoradiotherapy [CTRT])? In the absence of any guidelines, we reviewed our data with CT or CTRT to inform us regarding adequate therapy. MATERIALS AND METHODS: Patients of GBC post-SC referred to us (January 2008 to December 2016) were risk-stratified into three categories based on a diagnostic CT scan: No residual disease (NRD), limited volume residual disease (LR1: Residual/recurrent disease in GB bed with or without N1 nodal station involvement), advanced residual disease (LR2: Residual/recurrent disease involving GB bed with N2 nodal station involvement) and treated with CT or CT followed by CTRT...

BACKGROUND: The prognosis of patients with advanced biliary tract cancer (BTC) who have progressed on gemcitabine plus cisplatin is dismal. Trifluridine/tipiracil (FTD/TPI) and irinotecan have proven efficacy in different gastrointestinal malignancies. We therefore hypothesized that this combination might improve the therapeutic outcome in patients with BTC after failure of first line treatment. METHODS: TRITICC is an interventional, prospective, open-label, non-randomised, exploratory, multicentre, single-arm phase IIA clinical trial done in 6 sites with expertise in managing biliary tract cancer across Germany...

Neoplasms arising from the ampulla of Vater are exceedingly rare, and there is a paucity of literature regarding their diagnosis and management. Ampullary cancer typically presents with jaundice and signs of biliary obstruction. We present a case of ampullary adenocarcinoma with concomitant choledocholithiasis that proved complex and diagnostically challenging.

BACKGROUND: A majority of the patients with gall bladder cancer (GBCa) present at an advanced stage and have poor survival. The aim is to retrospectively study the role of guided FNA in the diagnosis of GBCa in a superspecialty institute and to describe the cytomorphologic spectrum of gall bladder (GB) lesions in the North Indian population. MATERIALS AND METHODS: All suspected cases of GBCa who underwent guided FNA from the primary GB mass or metastatic liver space-occupying lesion from 2017 to 2019 were included...

Gallbladder carcinoma (GBC) is the most common biliary tract malignancy associated with a concealed onset, high invasiveness and poor prognosis. Radical surgery remains the only curative treatment for GBC, and the optimal extent of surgery depends on the tumor stage. Radical resection can be achieved by simple cholecystectomy for Tis and T1a GBC. However, whether simple cholecystectomy or extended cholecystectomy, including regional lymph node dissection and hepatectomy, is the standard surgical extent for T1b GBC remains controversial...

Gallbladder carcinoma (GBC) is the most common of all biliary tract cancers. GBC is a multifactorial disease. Gallbladder dysplasia from any gallbladder inflammatory condition is one of the main risk factors for GBC. The late diagnosis of GBC is a major problem in its treatment. It is treated by radical resection and the prognosis is improved by adjuvant chemoradiation. We present a rare case of gall bladder cancer presenting as hepatic abscesses with severe sepsis. An 83-year-old male presented with progressive symptoms of shakiness, general weakness, vomiting, and profuse diarrhea...

OBJECTIVE: We aimed to identify new, more accurate risk factors of liver transplantation for liver cancer through using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS: Using the SEER database, we identified patients that had undergone surgical resection for non-metastatic hepatocellular carcinoma (HCC) and subsequent liver transplantation between 2010 and 2017. Overall survival (OS) was estimated using Kaplan-Meier plotter. Cox proportional hazards regression modelling was used to identify factors independently associated with recurrent disease [presented as adjusted hazard ratios (HR) with 95% CIs]...

BACKGROUND: FIGHT-102 was a phase 1, dose-escalation, dose-expansion study of pemigatinib in Japanese patients with advanced solid tumors. Here, we report safety, tolerability, and preliminary efficacy of pemigatinib from FIGHT-102. METHODS: Patients (≥20 years old) self-administered oral pemigatinib 9, 13.5, or 18 mg QD on intermittent dosing (Part 1) or 13.5 mg QD intermittent or continuous dosing (Part 2). A dosing cycle was 21 days (2 weeks on/1 week off or 21 continuous days)...
