Of 89 samples of cancer cells from ovarian cancer patients primary cultures representative of the cancer cell population could be established in 17. The clinical response to polychemotherapy was studied in relation to the inhibition of thymidine uptake by the cultured cells. Cultures of each patient's tumour were exposed to concentrations of the drugs the patients had been given for long enough to reproduce the area under the curve (AUC) of the plasma levels resulting from in vivo dosage. Full agreement was observed between the degree of thymidine uptake inhibition induced by at least one of the drugs administered to the cultured cells and the degree of clinical response. This approach may prove useful in pharmacological studies as a means of obtaining ovarian cancer cell populations representative of human tumours, even though the number of tumours that can be successfully evaluated in vitro is still too small to serve as a sound basis for prediction.
