Abstract
The National Cancer Institute cancer treatment screening program has been reorganized incorporating, as an important feature, a panel of human tumors growing as xenografts in congenitally athymic mice. The new screening program is a prospective experiment in the search for new and more effective agents for the treatment of clinical neoplasia. The new program is described and questions that are being asked prospectively are presented. Data are summarized on the activity against human tumor xenografts for a number of clinically established antitumor drugs and examples are presented in which there is interest in compounds for the clinic on the basis of activity in the new screen. Studies are outlined in which high dose thymidine inhibited the growth of human melanoma and teratocarcinoma transplanted in athymic mice. Studies are discussed employing murine tumors in which marked augmentation of the in vivo antitumor activity of 5-fluorouracil was obtained by combination therapy with the pyrimidine nucleosides thymidine, uridine and cytidine. The desirability of investigating combination chemotherapy with pyrimidine nucleosides and 5-fluorouracil and other pyrimidine antagonists in the treatment of human tumor xenografts is stressed. There is a broad range of investigations that can be conducted in nude mouse models and it is important to conduct such programs in relation to the clinic.This publication has 0 references indexed in Scilit:
