Patienterne skal overvåges under behandlingen, dels for at se, hvordan de reagerer, dels for at kontrol - lere blodets indhold af blodplader (de blodlegemer, der medvirker ved blodets størkning) og af neutro - filer (de hvide blodlegemer, der bekæmper infektioner).
Patients should be monitored during treatment to see how they respond, but also to check their blood levels of platelets (the components that help clotting) and neutrophils (the white blood cells that fight infection): if these are too low the treatment should be interrupted or stopped.
