Transplantation of human tumors into cortisone-treated hamsters.

Abstract

Summary 1.Transplantation of 33 human tumors into the cheek pouch of cortisone-treated hamsters has resulted in the ‘survival” of 70 per cent of the tumors for periods exceeding 12 days. 2.One epidermoid carcinoma, now called “Deac-1,” holds promise of being permanently transplantable. It has now been carried through sixteen generations of hamsters in a 9-month period. 3.Factors concerned in the eventual transplantation of other human neoplasms are briefly discussed, and possibilities for immediate clinical application of experimental data are suggested.
