Pharmacologie des dérivés du platine : différences entre les trois composés et les facteurs de variabilité entre patients

Platinum compounds represent a pharmacological class, essential for the treatment of some cancer diseases. The three molecules, cisplatin, carboplatin, and oxaliplatin, share some physiochemical and pharmacological properties, in particular the ability to form DNA adducts. However, oxaliplatin presents some mechanisms of resistance different to those of cisplatin and carboplatin. Carboplatin may be considered as an analogue of cisplatin, but its pharmacokinetic properties, side effects, and intrinsic activity are significantly different from those of cisplatin, then the choice of one of these two compounds may be done rationally in function of the patients' characteristics. The cellular mechanisms involved in these differences are described in this general review.
