Abstract:
:The pancreatic carcinogen N-nitrosobis(2-oxopropyl)-amine was administered to Syrian golden hamsters after cholecystoduodenostomy and choledochostomy to investigate a possible bile reflux mechanism as a factor in pancreatic carcinogenesis. The induced lesions were similar in morphology, multiplicity, and distribution to those of animals in other studies without surgery. Hence the findings contraindicate the importance of biliary reflux in pancreatic tumor induction. Other possible mechanisms are discussed.

CANCER RESEARCH文献大全abstract::Human prostate cancer has a high predisposition to metastasize to bone, resulting in the formation of osteoblastic metastases. The mechanism through which prostate cancer cells promote osteoblastic lesions is undefined. Vascular endothelial growth factor (VEGF) has been implicated as a mediator of osteoblast activity....
