Abstract

The present study was aimed at defining the standard conditions for predictive chemosensitivity testing of human leukaemias. The in vitro cytotoxic potential of 11 anticancer drugs against L1210 murine leukaemia was comparatively determined 3 and 48 h after in vitro exposure of leukaemia cells to these agents. In preliminary testing, drug-induced damage was estimated in terms of percent inhibition of: tumour cell proliferation, by microscopic determination of viable cell numbers; and DNA synthesis, by measuring the extent of incorporation of the labelled nucleoside 125IUdR. Since the two tests appeared to yield comparable results, all subsequent experiments on the various murine tumours were performed using the radiolabel incorporation technique. The results obtained pointed out that this metabolic assay performed 48 hours after drug exposure appears to be capable of predicting both "spontaneous" and "induced" in vivo resistance of murine leukaemias.
