Pancreatic ductal adenocarcinoma (PDAC) is the most lethal malignancy known, with an extremely poor prognosis due to the lack of an efficient diagnostic scheme and no radical treatment option, except surgery. Therefore, understanding the pathophysiology of, and finding a novel biomarker to detect, PDAC should be prioritized. We observed an increase...
Article
The meso-pancreatoduodenum is the primary site of tumor infiltration in patients with pancreatic head cancer, with numerous patients exhibiting lymph node metastases. Effective dissection of the regional lymphatic basin requires knowledge of the patterns of the arterial branches. The present study examined the patterns of the arteries feeding the p...

Article
Hepatic arterial infusion (HAI) chemotherapy with gemcitabine (GEM) is expected to be more effective and safer method to treat hepatic metastasis of pancreatic cancer compared with intravenous administration, because it affords higher tumor exposure with lower systemic exposure. Thus, a key issue for dose selection is the saturability of hepatic up...
