In the event of the ineffectiveness of total androgen blockade (TAB) therapy, cytostatic administration may be attempted. In this study, we modelled the drugs used in practice on human prostate cancer cell lines. Studies aimed at decreasing multidrug resistance were performed on PC-3 cells. With the use of various cytostatics, the cell proliferation-inhibiting effects were measured under in vitro conditions on human prostate cancer cell lines LNCaP-FGC and PC-3. Under the given experimental conditions, the examined cytostatics exhibited antiproliferative effects on each of the investigated cell lines. Our results indicate that it is not necessary to wait until the development of a hormone-resistant state. In the studies on the PC-3 cell line, we did not find a multidrug-resistant efflux activity responsible for the resistance of the tumour.
