INTRODUCTION: Gallstones are known to be associated with premalignant changes in the gallbladder epithelium that range from atypical hyperplasia, metaplasia, dysplasia to carcinoma. Recognition of factors associated with these changes in patients with gallstones can potentially be helpful in identifying patients to whom prophylactic cholecystectomy can be offered to reduce the chances of developing carcinoma. OBJECTIVE: To identify factors associated with premalignant epithelial changes including atypical hyperplasia, metaplasia, and dysplasia in gallbladder mucosa in patients with chronic calculus cholecystitis...

Gemcitabine-based therapy remains the mainstay of treatment for patients with biliary tract cancers (BTCs) with no second-line treatment(s) established yet. Aberrant activation of MAPK pathway in patients with BTC indicates its importance in BTC. Trametinib is a potent, highly selective, allosteric non-competitive inhibitor of MEK1/MEK2. In this Phase IIa open-label, single-arm study, we investigated efficacy and safety of trametinib in Japanese patients with advanced BTC refractory to gemcitabine-based therapy...

Arsenicosis, a syndrome caused by ingestion of arsenic contaminated drinking water, currently affects millions of people in South-East Asia and elsewhere. Previous animal studies revealed that the toxicity of arsenite essentially can be abolished if selenium is co-administered as selenite. Although subsequent studies have provided some insight into the biomolecular basis of this striking antagonism, many details of the biochemical pathways that ultimately result in the detoxification and excretion of arsenic using selenium supplements have yet to be thoroughly studied...

Verónica Urdaneta, Josep Casadesús
Bile salts and bacteria have intricate relationships. The composition of the intestinal pool of bile salts is shaped by bacterial metabolism. In turn, bile salts play a role in intestinal homeostasis by controlling the size and the composition of the intestinal microbiota. As a consequence, alteration of the microbiome-bile salt homeostasis can play a role in hepatic and gastrointestinal pathological conditions. Intestinal bacteria use bile salts as environmental signals and in certain cases as nutrients and electron acceptors...

Malignant neoplasms represent the second most common cause of death in men and women in the Czech Republic after cardiovascular diseases. The incidence, prevalence and mortality is recorded in the Czech National Cancer Registry. The most recent data available is from 2013, in this year there were 81 541 patients newly diagnosed with cancer and 26 944 people died of cancer. From a long-term perspective, the incidence of neoplasms is increasing and the mortality is decreasing. In the Institute of Forensic Medicine in Brno there were 480 cases of newly reported malignant tumors during the period 2010-2015, which were not known before the autopsy...

Crocodiles exist in unsanitary environments, feed on rotten meat, are often exposed to heavy metals such as arsenic, cadmium, cobalt, chromium, mercury, nickel, lead, selenium, tolerate high levels of radiation, and are amid the very few species to survive the catastrophic Cretaceous-Tertiary extinction event, nonetheless they can live for up to a 100 years. Moreover, as they live in unhygienic conditions, they regularly come across pathogens. Logically, we postulate that crocodiles have established mechanisms to defend themselves from noxious agents as well as protecting themselves from pathogens...

BACKGROUND: The prognosis of advanced (stage IV) cancer of the digestive organs is very poor. We have previously reported a case of advanced breast cancer with bone metastasis that was successfully treated with combined treatments including autologous formalin-fixed tumor vaccine (AFTV). Herein, we report the success of this approach in advanced stage IV (heavily metastasized) cases of gall bladder cancer and colon cancer. CASE PRESENTATION: Case 1: A 61-year-old woman with stage IV gall bladder cancer (liver metastasis and lymph node metastasis) underwent surgery in May 2011, including partial resection of the liver...

Extrahepatic bile duct obstruction can be caused by various pathologies, most of them being malignant. Painless, progressive jaundice is the usual mode of presentation. We report a case of distal Common Bile Duct (CBD) obstruction due to a Benign Intramural Beale gland hyperplasia mimicking a periampullary carcinoma. Peribiliary glands (Beale Glands) are a group of seromucinous glands, normally seen within the fibromuscular wall and periductal connective tissue in the extrahepatic and large intrahepatic ducts and also in the neck of the Gall bladder...

Breast Cancer (BC) has associated risk factors and genetic factors like BRCA1, and BRCA2. Many benign and malignant disease processes are found concurrently with BC and believed to be additional risk factors like gall bladder stones (cholelithiasis), hypertension, diabetes mellitus, cerebrovascular lesions, arthritis, spine and spinal cord degenerative lesions, infertility, depression, sleep disturbances, obesity, autoimmune diseases (SLE), and thyroid diseases. There are some malignant disease associations like synchronous or metachronous ovarian, colonic and endometrial tumours with Breast cancer...

Neuroendocrine tumors are the rarest tumors of gallbladder. The most aggressive variant is neuroendocrine carcinoma which presents in about 0.5% of all gallbladder carcinomas and 0.2% of all neuroendocrine tumors. It seems possible that survival rates can be improved by utilizing wide surgical resection combined with chemotherapy. We report a case of neuroendocrine carcinoma of gall bladder in a 20-year old female patient. In present case, the etiology was not known as patient did not have cholelithiasis or any symptoms related to chronic inflammation...

Silibinin (silybin), a non-toxic natural polyphenolic flavonoid, is the principal and the most biologically active component of silymarin. It is efficient in the treatment of acute and chronic liver disorders caused by toxins, drug, alcohol, hepatitis, and gall bladder disorders. Further, in our previous studies, we explored the anti-cancer efficacy in common cancers, such as lung, prostatic, colon, breast, bladder, as well as, hepatocellular carcinoma. Interestingly, silibinin is still not solely limited to the treatment of these diseases...

Gall Bladder Cancer (GBC) is an aggressive malignancy. The prognosis of metastatic GBC is dismal. Until recently, there are no standard treatment guidelines for management of patients with metastatic GBC. But the ultimate aim of any treatment modality is to improve the overall survival with good quality of life. We hereby report a long term survivor of metastatic GBC treated with initial six cycles of gemcitabine + cisplatin combination chemotherapy, but did not show any response. In view of chemotoxicity and as a matter of physician preference patient was started on low dose weekly 5- Fluorouracil monotherapy based on a metronomic chemotherapy principle...

INTRODUCTION: Gall bladder Wall Thickening (GWT) is caused by wide spectrum of diseases. Initially Ultrasound (USG) was used as imaging modality for screening of acute abdomen because of its high sensitivity and real time character. Now, Computed Tomography (CT) is used because of its high temporal and spatial resolution. AIM: Evaluation of GWT and its enhancement patterns on contrast enhanced CT scan in a bid to differentiate benign from malignant causes and to correlate the imaging features with clinical and histopathological findings...
