PRELIMINARY OBSERVATION ON PANCREATIC DUCT ADENOCARCINOMA INDUCED BY INTRADUCTAL ADMINISTRATION OF N‐ETHYL‐N′ ‐NITRO‐N‐NITROSOGUANIDINE IN DOGS

Pancreatic duct adenocarcinoma was induced by intraductal administration of N‐ethyl‐N′‐nitro N‐nitrosoguanidine (ENNG) in two mongrel dogs. A dog received a total dose of 595 mg of ENNG during 12 months and was sacrificed. Duct obstruction was detected by pancreatography and duct adenocarcinoma was...

Sumario:Pancreatic duct adenocarcinoma was induced by intraductal administration of N‐ethyl‐N′‐nitro N‐nitrosoguanidine (ENNG) in two mongrel dogs. A dog received a total dose of 595 mg of ENNG during 12 months and was sacrificed. Duct obstruction was detected by pancreatography and duct adenocarcinoma was found. Another dog was given a total dose of 350 mg of ENNG during 8 months and was sacrificed 26 months after the first administration of the carcinogen. Duct adenocarcinoma was found. No pancreatic tumors were found in 2 dogs given intraperitoneal N‐nitrosobis(2‐oxo‐propyl)amine at a total dose of 4000 mg or in 2 dogs given Tween 60 only. These results suggest that the direct presence of a carcinogen in the pancreatic duct was able to induce duct adenocarcinoma in dogs.
