Data concerning the pharmacokinetics of actinomycin D will provide useful information for investigating the importance of systemic exposure to this
agent in determining clinical response and toxicity.
This may be particularly valuable when we consider
the dose-related incidence of VOD observed in patients receiving actinomycin D treatment. Pharmacokinetic studies in children of different age groups may
give some indication why infants are more susceptible to this type of hepatotoxicity than older children.
These studies are currently being performed by the
UKCCSG in various clinical centres across the United
Kingdom.
