title: Experimental hyperthermic isolation-perfusion using cis-diamminedichloroplatinum(II).
abstract: The intent of this study was to determine whether or not local control and/or cure of rabbits bearing the VX-2 carcinoma could be achieved with regional hyperthermia and chemotherapy. A model of isolation-perfusion used cis-diamminedichloroplatinum(II) (DDP). Five different experimental groups were studied, each group receiving progressively smaller tumor inocula and shorter treatment intervals. Although local control and cure improved as the tumor inocula became smaller and treatment interval became shorter, there was no benefit demonstrated when compared to sham-operated animals. DDP appeared to be well tolerated in animals perfused as normothermic temperatures. However, animals perfused at hyperthermic temperature with DDP experienced necrosis of normal as well as neoplastic tissue, resulting in early demise of the animal. This final observation suggests that the amount of DDP utilized in clinical isolation-perfusion should be approached with caution.
