In pancreatic cancer (PC), adenosquamous carcinoma of the pancreas (PASC) containing both ductal adenocarcinoma and squamous carcinoma in the same tumor represents ~ 4% of the total incidence. To date, the genomic features of this mixed tumor are still unknown. We analyzed genomes of 17 PASCs and 34 ductal adenocarcinomas (PDACs), showing that PASC carried highly enriched TP53 mutations and 3p loss compared to PDAC. Furthermore, we uncovered that adenomatous and squamous components of PASC harbored comparable genomic alterations, suggesting that two cellular components are developed from the same progenitor cancer cells...

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...

INTRODUCTION: The ampulla of Vater consists of papilla, common channel, distal common bile duct and the distal main pancreatic duct. Ampullary carcinomas arise from two different types of mucosa, reflecting their broad histomorphological spectrum. Adenocarcinomas originating in the ampulla of Vater are classified as having either 'Intestinal' or 'Pancreatobiliary' type of differentiation. Pancreatobiliary type has consistently shown a worse prognosis. Various types of mucins are distributed in normal tissues and gastrointestinal tumours...

BACKGROUND: Lung adenosquamous carcinoma (ASC) is a rare malignant tumor with an adenocarcinoma and a squamous cell carcinoma component and associated with a lower 5-year survival rate than lung squamous cell carcinoma and lung adenocarcinoma. Surgical specimen histology revealed the inadequacy of conventional transbronchial needle aspiration samples in the diagnosis of lung ASC. Most lung ASC patients are not suitable to receive surgery, and it is difficult to diagnose ASC. This study is to explore the possibility of using serum carcinoembryonic antigen (CEA) and squamous cell carcinoma antigen (SCC) as a supplementary diagnostic test for ASC...

The enzyme NQO1 is a potential target for selective cancer therapy due to its overexpression in certain hypoxic tumors. A series of prodrugs possessing a variety of cytotoxic diterpenoids (oridonin and its analogues) as the leaving groups activated by NQO1 were synthesized by functionalization of 3-(hydroxymethyl)indolequinone, which is a good substrate of NQO1. The target compounds (29a-m) exhibited relatively higher antiproliferative activities against NQO1-rich human colon carcinoma cells (HT-29) and human lung carcinoma (A549) cells (IC50 = 0...
