BACKGROUND AND PURPOSE: Systemic inflammation is known to promote carcinogenesis in biliary tract cancer (BTC). Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are indicative of systemic inflammation. We evaluated the clinical significance of systemic inflammation measured by NLR and PLR in patients with advanced BTC. Additionally, we also co-analyzed the dynamics of NLR and PLR during chemotherapy. METHODS: We reviewed 450 patients with unresectable BTC receiving palliative chemotherapy...

Gallbladder carcinoma (GBC) is the most common biliary tract malignancy with high mortality. The median survival time is 6 months, and the 5-year survival rate less than 5% for GBC patients. Thus, it is imperative to investigate the molecular mechanisms underlying the pathogenesis of GBC. miR-133a may exert anti-tumor effects on a variety of cancers. However, the role of miR-133a in the pathogenesis of GBC remains unclear. In this study, quantitative real-time polymerase chain reaction (qRT-PCR) showed the miR-133a-3p expression markedly decreased in GBC as compared to adjacent normal tissues...

Gallbladder cancer (GBC) is the most common and aggressive form of biliary tract carcinoma with an alarmingly low 5-year survival rate. Despite its high mortality rate, the underlying mechanisms of GBC pathogenesis are not completely understood. Recently, from a growing volume of literature, long non-coding RNAs (lncRNAs) have emerged as key regulators of gene expression and appear to play vital roles in many human cancers. To date, a number of lncRNAs have been implicated in GBC, but their potential roles in GBC have not been systematically examined...

Bithynia siamensis goniomphalos is a freshwater snail that serves as the first intermediate host of the human liver fluke Opisthorchis viverrini. This parasite is a major public health problem in different countries throughout the Greater Mekong sub-region (Thailand, southern Vietnam, Lao PDR and Cambodia). Chronic O. viverrini infection also results in a gradual increase of fibrotic tissues in the biliary tract that are associated with hepatobiliary diseases and contribute to cholangiocarcinoma (a fatal type of bile duct cancer)...

The benefits of radiotherapy for inoperable biliary tract cancer remain unclear due to the lack of randomized data. We evaluated the impact of radiotherapy on survival in elderly patients using the SEER-Medicare database. Patients in the SEER-Medicare database with inoperable biliary tract tumors diagnosed between 1998 and 2011 were included. We used multivariate logistic regression to evaluate factors associated with treatment selection, and multivariate Cox regression and propensity score matching to evaluate treatment selection in relation to subsequent survival...

Advanced biliary tract cancers (ABTC) are among the deadliest malignancies with limited treatment options after progression on standard-of-care chemotherapy, which includes gemcitabine (GEM) and oxaliplatin (OX). The epidermal growth factor receptor inhibitor erlotinib has been explored in ABTC with modest efficacy. Erlotinib given continuously may antagonize the action of chemotherapy against cycling tumor cells, but pulsatile dosing of erlotinib with chemotherapy may improve efficacy. The purpose of this study was to assess the safety of pulsatile erlotinib with GEMOX...

Multiple myeloma is a plasma cell tumor that homes to and expands in the bone marrow and that, despite the new available drugs, remains incurable. Extramedullary plasmacytoma is a not frequent manifestation during the natural history of multiple myeloma and is frequently associated with plasma cell bone marrow infiltration. The most common locations for an EMP include the gastrointestinal tract, pleura, testis, skin, peritoneum, liver, endocrine glands, and lymph nodes. Primary involvement of the gallbladder fossa is exceedingly rare...

Biliary tract cancers represent an uncommon, heterogenous malignant group of tumors that include gallbladder cancers (GBC) and cholangiocarcinomas that are frequently detected in the locally advanced or metastatic setting. The randomized phase III ABC-02 trial established the combination regimen of cisplatin plus gemcitabine as standard of care therapy. Nevertheless, despite prior and subsequent attempts utilizing a variety of treatment strategies clinical outcomes for these cancers remains disappointing, necessitating the innate call for improvements in treatment approaches...

Biliary tract cancers (BTC) are aggressive gastrointestinal malignancies that are associated with a poor prognosis. This rare group of tumors includes cancers of the gallbladder, intrahepatic, and extrahepatic biliary tree. Chronic inflammatory processes such as cholelithiasis and chronic bacterial infection of the biliary system remain the most common underlying risk factor although most cases occur sporadically. The majority of patients present with advanced disease accompanied by nonspecific symptoms, making BTCs a therapeutic challenge for clinicians...

Biliary tract cancers (BTC) are malignancies that arise from the epithelium of the biliary system and comprise the second most common type of hepatobiliary cancer worldwide. BTC are sub-classified as intrahepatic cholangiocarcinoma (iCCA), perhilar/hilar cholangiocarcinoma (pCCA), distal cholangiocarcinoma (dCCA), and gallbladder carcinoma. Due to the differences in their etiologic risk factors, pathogenesis, and molecular and genetic characteristics, each of these subtypes is considered a separate biological entity...

Biliary tract cancers (intrahepatic, perihilar and extrahepatic cholangiocarcinoma, and gallbladder and cystic duct cancers) are uncommon but highly lethal malignancies. Clinical presentation is often late, precluding curative surgical resection in most cases. For advanced disease, therapeutic options are limited to systemic chemotherapy, with suboptimal outcomes. An understanding of the molecular characteristics of biliary tract cancers may allow the clinical development of therapies targeting actionable alterations with the ultimate goal of improving clinical outcomes...

Involuntary weight loss, a part of the cachexia syndrome, is a debilitating co-morbidity of cancer and currently has no treatment options. Results from a recent clinical trial at our institution showed that biliary tract cancer patients treated with a MEK inhibitor exhibited poor tumor responses, but surprisingly gained weight and increased their skeletal muscle mass. This implied that MEK inhibition might be anti-cachectic. To test this potential effect of MEK inhibition, we utilized the established Colon-26 model of cancer cachexia and the MEK½ inhibitor MEK162...
