title: [Comparison between intraperitoneal and intravenous 5-fluorouracil administration using pancreatic cancer model of nude mouse].
abstract: Carcinoma of the pancreas is a virulent malignancy. The purpose of this study was to evaluate the efficiency of 5-FU intraperitoneal administration for this malignancy. We developed a pancreatic cancer model whereby a human pancreatic cell line, MIA PaCa-2, was orthotopically transplanted to the pancreas of nude mice as cell suspension (1 x 10(6) cells). IP group (n = 6) received 5 times IP administration (4, 7, 12, 16, 20 days after implantation) of 5-FU 50 mg/kg, 1.5 ml. IV group (n = 6) received 5 times IV therapy (the same dates as IP group) of 5-FU 50 mg/kg, 0.2 ml. Control group (n = 6) received no treatment. The mice were sacrificed 42 days after implantation. The weight of the tumors of IP, IV and Control group was 0.332 +/- 0.143 g, 0.138 +/- 0.047 g and 0.329 +/- 0.085 g. Significant differences were found between IP and IV, and control. There was no difference between IP and control. This experiment demonstrated that 5 FUIP therapy for primary pancreatic cancer showed no effect and 5 FUIV therapy was much more effective.
