BACKGROUND: There is limited literature about the clinicopathological characteristics and outcomes of rare histologic variants of gallbladder cancer (GBC). METHODS: Using SEER database, surgically managed GBC patients with microscopically confirmed adenocarcinoma, adenosquamous/squamous cell carcinoma and papillary carcinoma were identified from 1988 to 2009. Patients with second primary cancer and distant metastasis at presentation were excluded. The effect of clinicopathological variables on overall survival (OS) and disease specific survival (DSS) were analyzed using univariate and multivariate proportional hazards modeling...

INTRODUCTION: Gallbladder carcinoma has limited therapeutic options and a poor outcome with conventional therapy. Program death ligand (PD-L1) has been used as a potential target for immune checkpoint inhibitors in various solid neoplasms. PD-L1 expression has been studied in very few cases of gallbladder cancer. MATERIALS AND METHODS: 174 cases of gallbladder carcinoma were evaluated for PD-L1 expression using SP263 clone in tissue microarray. Clinico-pathological characteristics and survival data were correlated with PD-L1 expression analysed at different cut-offs of ≥1%, ≥10% and ≥50% in tumour cells and tumour infiltrating lymphocytes (TILs)...

Fibroblast growth factor-19 (human FGF19; murine FGF15) suppresses bile acid synthesis. In FGF19 deficiency, diarrhea resulting from bile acid spillage into the colon mimics irritable bowel syndrome. To seek other consequences of FGF19/15 deficiency, we used Fgf15 -/- and wild-type (WT) mice to assess gallbladder filling, the bile acid pool, fecal bile acid levels, and colon neoplasia. We fasted mice for six hours before assessing gallbladder size by magnetic resonance imaging (MRI). We measured bile acid levels in different compartments by enzymatic assay, and induced colon neoplasia with azoxymethane (AOM)/dextran sodium sulfate (DSS) and quantified epithelial Ki67 immunostaining and colon tumors 20 weeks later...

BACKGROUND: Neutrophil-Lymphocyte Ratio (NLR) and Platelet-Lymphocyte Ratio (PLR) have been considered as indicators for prognosis in various cancers. However, the prognostic values of NLR and PLR have never been tested in gallbladder carcinoma (GBC) with hepatic involvement. OBJECTIVE: The aim of the current study was to assess the prognostic significance of NLR, PLR, and other candidate biomarkers in GBC with liver involvement. METHODS: Receiver operating characteristic (ROC) curve analyses were utilized to pinpoint the cut-off values for NLR, PLR, and Monocyte-Lymphocyte Ratio (MLR)...

Background: Tumor necrosis factor alpha (TNF-α) enhances lymphangiogenesis in gallbladder carcinoma (GBC) via activation of nuclear factor (NF-κB)-dependent vascular endothelial growth factor-C (VEGF-C). Receptor-interacting protein 1 (RIP1) is a multifunctional protein in the TNF-α signaling pathway and is highly expressed in GBC. However, whether RIP1 participates in the signaling pathway of TNF-α-mediated VEGF-C expression that enhances lymphangiogenesis in GBC remains unclear...

RATIONALE: Gallbladder adenocarcinoma is the most common subtype of malignant tumor in gallbladder carcinoma; its incidence is quite low. Preoperative diagnosis of gallbladder adenocarcinoma appears to be very difficult because they are normally asymptomatic and are often found incidentally. Adenocarcinoma with sarcomatoid carcinoma of gallbladder is exceedingly rare with no case reported in the literature to date. PATIENT CONCERNS: A 69-year-old male was referred to our hospital due to right upper quadrant pain...

Laparoscopic radical cholecystectomy for gallbladder cancer (GBC) has been performed at various oncology centres reporting its technical feasibility. Considering GBC an aggressive malignancy, laparoscopic radical cholecystectomy should be dealt with caution. We recently encountered a case of carcinoma gallbladder who underwent laparoscopic radical cholecystectomy elsewhere and presented with early recurrence. The patient's records were evaluated and he underwent re-resection. Hereby, we discuss the factors that could lead to early recurrence after laparoscopic radical cholecystectomy and measures that can be taken to prevent it...

The exact pathogenesis of gallbladder adenomyomatosis is still lacking and some controversies over its diagnosis and treatment exist. Originally recognized as a precancerous lesion, adenomyomatosis is currently recognized by recent studies as a benign alteration of the gallbladder that is often associated with cholecystitis and cholecystolithiasis. Gallbladder carcinoma is an extremely malignant disease with a 5-year survival rate of less than 5%. Therefore, it is important to diagnose, differentiate, and confirm the relationship between adenomyomatosis and early-stage gallbladder carcinoma...

Biliary carcinoma includes intrahepatic cholangiocarcinoma, hilar cholangiocarcinoma, distal cholangiocarcinoma, and gallbladder cancer. There are few studies about laparoscopic treatment for biliary malignancy due to the complicated dissection of porta hepatic structure, and even reconstruction of biliary tract and(or) vessel under laparoscopy, which increases the difficulty of the laparoscopic radical resection of biliary malignancy. To promote the standardized application and development of laparoscopic techniques in operation of biliary malignancy, the safety and effectiveness of laparoscopic techniques are explained in this paper...

Pancreatic neoplasms, including ductal adenocarcinoma, solid pseudopapillary neoplasm, pancreatic endocrine neoplasms, acinar cell carcinoma, and pancreatoblastoma, are associated with different genetic abnormalities. Hepatic adenomas with beta-catenin exon 3 mutation are associated with a high risk of malignancy. Hepatic adenoma with arginosuccinate synthetase 1 expression or sonic hedgehog mutations are associated with a risk of bleeding. Hepatocellular carcinoma and choangiocarcinoma display heterogeneity at both morphologic and molecular levels Cholangiocellular carcinoma is most commonly associated with IDH 1/2 mutations...

INTRODUCTION: The incidence of gallstone disease is increasing and represents a strain on healthcare systems worldwide. Following cholecystectomy, gallbladder specimens are generally submitted for histopathologic examination and the diagnostic yield of this strategy remains questionable. This study aimed to evaluate the usefulness of routine pathologic examination of the gallbladder specimens and investigate the results of routine postoperative follow-up visits. METHODS: All cholecystectomies performed between January 2011 and July 2017 at a single center were evaluated...
