Introduction: Biliary tract cancer (BTC) originates from the biliary epithelium of the small ducts within the liver (intrahepatic cholangiocarcinoma, IHCC), the main ducts of the hilum (extrahepatic cholangiocarcinoma, EHCC), or in the gallbladder (gallbladder cancer, GC). Due to presentation with nonspecific symptoms as well as absence of screening, most patients present with advanced disease and unfavorable prognosis.

Areas Covered: The ABC-02 trial established the current first-line chemotherapy with gemcitabine/platinum for advanced BTC in 2010.

Tumor necrosis factor (TNF) has been recognized as an immune activation factor in tumor immunotherapy. Our study demonstrated that TNF blockade markedly enhanced the antitumor efficacy of oncolytic adenovirus (AdV) therapy. To minimize systemic side effects, we engineered a recombinant oncolytic AdV encoding a TNF inhibitor (AdV-TNFi) to confine TNF blockade within the tumor microenvironment (TME).

Background: Gemcitabine (Gem) is one of the first-line chemotherapy drugs for pancreatic cancer treatment. However, its short half-life in plasma and adverse effects limited its broader application.

Methods: A novel Gem derivative ( -tetradecyloxycarbonyl gemcitabine, tcGem) was synthesized and encapsulated into liposomes (LipotcGem) to overcome the above shortcomings.

Pancreatic ductal adenocarcinoma has a unique tumor microbiome and the systemic depletion of bacteria or fungi using antibiotic/antifungal cocktails leads to a decrease in pancreatic tumor burden in mice. However, functional studies remain rare due to the limited availability of clinically relevant microbiota. Here, we describe in detail the isolation of bacteria and fungi from the small intestine and tumor of pancreatic cancer patients at the Rogel Cancer Center.

Background: Intrahepatic cholangiocarcinoma is a malignant tumor that starts from the epithelium of the bile duct and has a poor prognosis. They are characterized by poor response to chemotherapy and lack of effective targeted therapies; thus, therapeutic options are limited.

Case Presentation: A 59-year-old man was admitted to the hospital for a workup of abnormal CA19-9 levels.
