DR-027 De rol van famacogenetica bij verworven tumorresistentie

The effect of anti-cancer drugs depends on the amount of drug that is present in the tumor cells. If these tumor cells have decreased uptake or increased excretion of a drug, the tumor has less exposure to the drug and therefore the drug might be less effective. Uptake and excretion of drugs is regulated by drug transporters, which we will investigate at DNA level. If (subtypes of) tumors have reduced exposure via this mechanism, it might be beneficial to give higher doses of that drug or to switch to an alternative drug.
