Biliary tract cancers, including gallbladder cancer, intrahepatic, perihilar, and distal cholangiocarcinomas, although anatomically contiguous, represent a heterogeneous group of cancers with extensive biologic and genetic diversity. With early disease, surgical resection is the preferred option for all subtypes; however, relapse rates remain high, and survival outcomes are poor. Data to guide the use of adjuvant therapy have been limited to retrospective series, population-based studies, and meta-analyses, all with their associated limitations...

Gallbladder cancer (GBC) is a rare malignancy of biliary tract cancer (BTC), characterized by late presentation and poor prognosis. It exhibits wide geographical as well as ethnical variations. So, diverse epidemiology along with etiological factors have been discussed in the current article. Present review unravels the germ line polymorphisms contributing to GBC susceptibility through candidate gene approach and GWAS. GBC is enriched with multiple mutations consisting of both passenger and driver mutations...

BACKGROUND: Gallbladder polyp (GBP) surveillance seeks to identify early neoplasms, but practice varies amongst surgical units. Recent European consensus guidelines have recommended an evidence-based GBP surveillance strategy. In a tertiary centre Hepato-Pancreato-Biliary unit we examine GBP surveillance, malignant yield, and assess cost-effectiveness of the new European consensus guidelines. METHODS: Respective data were collected from all patients with ultrasonography-detected GBPs between January 2008 and January 2013...

Gallbladder cancer (GBC) is a highly malignant bile duct cancer with poor prognosis due to early invasion and metastasis. However, the molecular mechanisms through which GBC cells interact with the tumor microenvironment (TME) remain poorly understood. Here, we examined the role of the tumor suppressor apoptosis-stimulating of p53 protein 2 (ASPP2) in regulating GBC invasion and metastasis and macrophage recruitment. The clinicopathological significance of ASPP2 expression was measured by immunohistochemical analysis in 72 patients with GBC...

Carbohydrate antigen 19-9 (CA19-9) fails to demonstrate the predictive value for early detection pancreatic ductal adenocarcinoma (PDAC). Glypican-1 (GPC1+) exosomes may serve as a noninvasive diagnostic tool to detect early stages of PDAC. Therefore, it is necessary to explore the serum GPC1 levels and determine whether serum GPC1 serves as a novel biomarker for PDAC patients. Blood samples were collected from 156 patients with PDAC, 199 non-cancer controls, and 240 patients with other cancers. Serological levels of GPC1 were examined by enzyme-linked immunosorbent assay (ELISA)...

The uncommonness of gallbladder cancer in the developed world has contributed to the generally poor understanding of the disease. Our integrated analysis of whole exome sequencing, copy number alterations, immunohistochemical, and phospho-proteome array profiling indicates ERBB2 alterations in 40% early-stage rare gallbladder tumors, among an ethnically distinct population not studied before, that occurs through overexpression in 24% (n=25) and recurrent mutations in 14% tumors (n=44); along with co-occurring KRAS mutation in 7% tumors (n=44)...

Extrahepatic bile duct cancer (EBDC) is a combined type of malignancy mainly consisting of extrahepatic cholangiocarcinoma and gallbladder cancer. Clinically, it is featured with latent symptoms and early metastasis, leading to a poor prognosis. Therefore, this cohort study aimed to depict the possible metastatic patterns of EBDC of diverse sub-types and evaluate the prognostic significance of diverse metastatic destinations with data from the clinical database. Relevant data of total 4061 confirmed EBDC patients diagnosed between 2010 and 2013 from the Surveillance, Epidemiology and End Results (SEER) database was obtained...

Background: Mirizzi syndrome is a condition difficult to diagnose and treat, representing a particular "challenge" for the biliary surgeon. The disease can mimic cancer of the gallbladder, causing considerable diagnostic difficulties. Furthermore, it increases the risk of intraoperative biliary injury during cholecystectomy. The aim of this study is to point out some particular aspects of diagnosis and treatment of this condition. Methods: The clinical records of patients with Mirizzi syndrome, treated in the last five years, were reviewed...

Gallbladder cancer (GBC) is a rare gastrointestinal tumour. It occurs in women with pre-existing cholelithiasis. These tumours pose therapeutic as well as diagnostic challenges to treating clinicians. Early suspicion and optimal surgery for suspected GBC results in the best outcome. We describe two cases of metastatic GBC initially treated by simple cholecystectomy for gallstone despite disease pointers towards a malignant pathology. Subsequent presentation was with histopathologically proven metastatic GBC...

BACKGROUND: Incidental gallbladder cancer (iGBC) is on the rise world over. This may be a good scenario as we get to treat GBC in early stages. However, there is a practice of diagnosing patients based on clinicoradiological findings alone and subjecting them to a radical surgical procedure. This approach over-treats patient and has important implications for resource utilization. METHODS: We performed a retrospective analysis of 284 consecutive patients undergoing upfront surgery for suspected GBC from January 2010 to December 2016...

There are no neuroectodermal cells in the gallbladder mucosa. Therefore, gallbladder neuroendocrine carcinoma (NEC) is extremely rare and has a poor prognosis. We report a case of a Japanese man in his 60s with this disease. The patient visited a family doctor for epigastralgia. Blood tests showed no abnormalities, including tumor markers, such as CEA and CA19-9. Abdominal ultrasonography (US) showed a low-echoic mass, 39 × 30 mm, with clear boundaries to the liver from the fundus of the gallbladder. Contrast-enhanced computed tomography showed that the tumor was enhanced early and washed out...

Gallbladder cancer is a rare malignancy of the biliary tract with a poor prognosis, frequently presenting at an advanced stage. While rare in the United States overall, gallbladder cancer has an elevated incidence in geographically distinct locations of the globe including Chile, North India, Korea, Japan and the state of New Mexico in the United States. People with Native American ancestry have a much elevated incidence of gallbladder cancer compared to Hispanic and non-Hispanic white populations of New Mexico...

BACKGROUND: Current consensus guidelines suggest that gallbladder cancer (GBC) patients with resected T1a disease can be observed while patients with T1b or greater lesions should undergo lymphadenectomy (LNE). The primary aim of this study was to critically explore the impact of LNE in early-stage GBC on overall survival (OS) on a population-based level. METHOD: The 2004-2014 National Cancer Database was reviewed to identify non-metastatic GBC patients with T1a, T1b, or T2 disease and grouped whether a dedicated LNE was performed...

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...

WNT inhibitory factor 1 (WIF‑1) is involved in the tumorigenicity and progression of several types of tumor, which has been attributed to aberrant hypermethylation of its promoter. However, the role of WIF‑1 in the pathogenesis of gallbladder cancer (GBC) remains to be fully elucidated, and the data available are insufficient to identify the upstream molecular mechanisms involved. In the present study, the methylation status of the WIF‑1 promoter was investigated using methylation‑specific polymerase chain reaction (PCR) and bisulfate sequencing PCR in GBC cells...
