Sensitivity of human non-small cell lung cancer xenografts to cyclophosphamide and cisplatin.

In order to establish the usefulness of the nude-mouse human tumour xenograft system as a predictive screen for antineoplastic agents, the antitumour activity of cyclophosphamide (CTX) and cisplatin (DDP), two clinically active drugs, was tested against a panel of 14 human non-small cell lung tumour xenografts and the experimental results were compared with the clinical results reported in the literature. The poor clinical response of non-small cell tumours was reflected in the lack of response of the xenograft tumours to these two agents.
