Transplantation studies revealed that a human epidermoid carcinoma, H.Ep. #3, can grow in conditioned adult dogs; but toxic, or near-lethal, doses of x-radiations and cortisone are required for transplants to grow. Because of these limitations, cortisone treated and x-radiated adult dogs bearing human tumor transplants are not amenable for long-term experimental chemotherapy studies.
