PURPOSE: Gallbladder cancer (GBCA) is an uncommon malignancy with vague and non-specific symptoms. GBCA is sometimes diagnosed after emergency cholecystectomy for acute cholecystitis. We investigated the differential diagnosis between GBCA with acute cholecystitis. MATERIALS AND METHODS: Thirteen patients were diagnosed with GBCA after emergency cholecystectomy carried out for acute cholecystitis. A radiologist who was blinded to the final diagnoses retrospectively reviewed the computed tomography (CT) scans of the patients with GBCA and 25 patients with acute cholecystitis...

Adenosquamous carcinoma (ASC) of the gallbladder is a rare malignant tumor that is characterized by a coexisting of glandular and squamous components. In a case of ASC, we performed hotspot multigene mutational profiling of 164 hotspot regions of eleven cancer-associated genes (AKT1, APC, BRAF, CTNNB1, KIT, KRAS, NRAS, PDGFRA, PIK3CA, PTEN and TP53) in the two microdissected components. Both tumor phenotypes resulted characterized by a p.E542K point mutation in the PIK3CA gene, whereas adenocarcinoma component revealed also a TP53 Q331* homozygous stop mutation...

Biliary tract cancer (BTC) is one of the most devastating types of malignant neoplasms worldwide. However, the mechanisms underlying the development and progression of BTC remain unresolved. BTC includes extrahepatic bile duct carcinoma (EBDC), gallbladder carcinoma (GBC) and ampulla of Vater carcinoma (AVC), named according to the location of the tumor. Although genetic alterations of intrahepatic cholangiocarcinoma have been investigated, those of EBDC, GBC and AVC have not yet been fully understood. The present study analyzed somatic mutations of 50 cancer-associated genes in 27 Japanese BTC cells, including: 11 EBDC, 14 GBC and 2 AVC...

Gallbladder cancer is a malignancy of biliary tract which is infrequent in developed countries but common in some specific geographical regions of developing countries. Late diagnosis and deprived prognosis are major problems for treatment of gallbladder carcinoma. The dramatic associations of this orphan cancer with various genetic and environmental factors are responsible for its poorly defined pathogenesis. An understanding to the relationship between epidemiology, molecular genetics and pathogenesis of gallbladder cancer can add new insights to its undetermined pathophysiology...

BACKGROUND: In limited metastatic burden of disease, stereotactic body radiotherapy (SBRT) has been shown to achieve high local control rates. It has been hypothesized that SBRT may translate to a better quality of life by delaying the need for systemic chemotherapy and possibly increasing survival. There is limited published literature on the efficacy of SBRT in limited nodal metastases. The primary aim is to review institutional outcomes of patients with solitary or oligometastatic lymph nodes treated with SBRT...

Biliary tract cancers (BTCs) are a heterogeneous group of tumours with geographical discrepancies in terms of incidence and risk factors. However, a convergent genomic and epigenetic mutational landscape emerges from the genome-wide screens of BTCs in South East Asia, Latin America and in the Western World. Specificities are observed for some alterations and anatomical subtypes: frequent fibroblast growth factor receptor 2 (FGFR2) and isocitrate dehydrogenase 1/2 (IDH1/2) alterations are specific to intrahepatic cholangiocarcinomas (ICCs), whereas frequent ERBB2 oncogene alterations are specific to extrahepatic cholangiocarcinomas (ECCs) and gallbladder carcinomas (GBCs)...

A growing number of studies indicated that long non-coding RNAs (lncRNAs) determine some cellular processes in cancer, such as proliferation, metastasis and differentiation. Urothelial carcinoma associated 1 (UCA1), an lncRNA, had been reported for its overexpression and oncogenic effect on various human cancers. In this study, we found that UCA1 was significantly overexpressed in gallbladder cancer (GBC) and positively correlated with tumor size, lymph node metastasis, TNM stage and short survival time. Moreover, UCA1 promoted GBC cell proliferation and metastasis in vitro and tumor growth in vivo...

Pancreaticobiliary maljunction (PBM) is the anomalous union of the main pancreatic duct and common bile duct outside the Oddi-sphincter, allowing the reflux of pancreatic juice to the gallbladder. There is only limited awareness and understanding of the pathologic correlates of this condition, mostly from Japan; this entity is largely unrecognized in the West. In this study, 76 gallbladders from patients with PBM (64 from Japan; 12 from the United States) were analyzed and contrasted with 66 from non-PBM patients...

BACKGROUND: Although surgical resection is the only curative treatment for gallbladder cancer (GBC), concomitant peritoneal dissemination is considered far beyond the scope of resection. We report a long-term survivor with a residual GBC with multiple peritoneal disseminations who underwent an extended resection after effective chemotherapy. CASE PRESENTATION: A 59-year-old male underwent an open cholecystectomy for Mirizzi syndrome at a local hospital. Because of severe inflammation, the gallbladder was perforated during surgery, ending in a piecemeal resection...

BACKGROUND: Resection surgery for pancreaticobiliary malignancies carries significant morbidity and mortality. Hence, preoperative assessment to exclude unresectable disease is mandatory. CT abdomen is the primary modality for staging of pancreaticobiliary cancers. However, some patients have malignant mediastinal lymphadenopathy (MML), which may be detected on endoscopic ultrasound (EUS) but not on CT scan. METHODS: We prospectively evaluated 75 consecutive patients (median age 54 years: 44 men) with a diagnosis of resectable pancreaticobiliary cancer (carcinoma gallbladder, carcinoma pancreas, cholangiocarcinoma, or periampullary carcinoma) for the presence of MML using EUS by an experienced endosonographer...

Mucosa-associated lymphoid tissue (MALT) lymphoma is rarely observed in the gallbladder, and its diagnosis before surgery is difficult. This report describes a case of primary MALT lymphoma of the gallbladder in an 80-year-old man. Imaging studies revealed a protruding lesion on the inside of the gallbladder, which led us to diagnose gallbladder carcinoma prior to the patient undergoing extended cholecystectomy. Microscopic examination of the resected specimen of the gallbladder demonstrated lymphoid follicles with atypical lymphocytes and the formation of lymphoepithelial lesions...

Mucoepidermoid carcinoma of the gastrointestinal tract is a rare entity. Here, we report a case of mucoepidermoid carcinoma of the transverse colon in a 77-year-old woman who presented with a 2-month history of epigastrium pain, diarrhea and melena. A giant tumor with apparently invading gallbladder was found by enhanced CT scan, then the extended resection of transverse colon was performed for the patient 2 weeks later. Microscopically, the tumor was composed of solid nests of epidermoid and Periodic Acid-Schiff (PAS)-positive mucin-producing cells with desmoplastic stroma...
