Radiosensitivity of drug-resistant human tumour xenografts

Strahlenther Onkol. 1989 Dec;165(12):870-2.

Abstract

The radiosensitivity of three drug-resistant sublines of a human epidermoid lung carcinoma growing as xenografts in nude mice was investigated. Drug resistance to vincristine, actinomycin D and cisplatin was developed in vivo by repeated drug treatment. It was found that all three drug-resistant tumour lines were not cross-resistant to irradiation.
