INTRODUCTION: Secondary pancreatic tumors are uncommon and account for 2-5% of pancreatic cancer. Tumors characterized most commonly with pancreatic involvement are lymphoma, renal cell and lung carcinomas. PRESENTATION OF CASE: A 76-year-old female patient with obstructive jaundice as the primary symptom and inguinal lymphadenopathy is presented. Imaging revealed a bulky solitary solid pancreatic head mass along with paraaortic and mesenteric lymphadenopathy. The absence of a previous history of malignancy and the presence of a dominant pancreatic mass along with distal lymphadenopathy confined differential diagnosis to advanced secondary pancreatic lymphoma, which is the most common secondary pancreatic tumor, and locally advanced/metastatic pancreatic adenocarcinoma...

Mitogen-activated protein kinases (MAPKs) are the main regulators of cellular proliferation, growth, and survival in physiological or pathological conditions. Aberrant MAPK signaling plays a pivotal role in carcinogenesis, which leads to development and progression of human cancer. Dual-specificity phosphatase 6 (DUSP6), a member of the MAPK phosphatase family, interacts with specifically targeted extracellular signal-regulated kinase 1/2 via negative feedback regulation in the MAPK pathway of mammalian cells...

A 73-year-old woman with chief complaint of macroscopic hematuria was diagnosed as having left renal tumor with pancreatic invasion. Nephrectomy was performed. Pathological diagnosis was clear cell carcinoma, pT3a. Three months after the operation, liver metastasis appeared and sunitinib was started. Most of the liver metastases disappeared; however, a new lesion appeared, and sunitinib was switched to axitinib, which was effective on the residual lesion, but the new lesion had poor response. Transarterial chemoembolization was performed to treat the liver metastases, and all metastatic lesions disappeared...

Tetrahydrolipstatin (THL), its enantiomer, and an additional six diastereomers were evaluated as inhibitors of the hydrolysis of p -nitrophenyl butyrate by porcine pancreatic lipase. IC50 s were found for all eight stereoisomers ranging from a low of 4.0 nM for THL to a high of 930 nM for the diastereomer with the inverted stereocenters at the 2,3,2'-positions. While the enantiomer of THL was also significantly less active (77 nM) the remaining five stereoisomers retained significant inhibitory activities (IC50 s = 8...

Heme oxygenase-1 (HO-1), a stress-response protein, is highly induced in various carcinomas. It is implicated in carcinogenesis and tumor progression. High HO-1 expression is associated with better prognosis of patients with colorectal and gastric cancers. Induction or inhibition of HO-1 can mediate chemo-sensitivity, therefore it might be a therapeutic target to develop anticancer agents. To define the clinicopathological and prognostic significance of HO-1 expression in small-intestinal adenocarcinomas (SIACs), immunohistochemical microarray analysis of HO-1 expression was performed for 191 surgically resected SIAC cases and results were compared with various clinicopathologic variables, including survival...
