Abstract
Attempts to define optimum chemotherapy in the clinical setting have resulted in a plethora of schedules and combinations. In addition various schemes are used to reduce doses and delay treatments in order to reduce toxicity. These schedules and schemes have obscured dose-response relationships which, however, can be rediscovered and studied by reducing all to how much drug is given per unit time, as mg/m2/wk regardless of the protocol schedule used. This is dose intensity (1). Dose intensity can be calculated from intended drug doses (“projected dose intensity”) or doses received after reductions and delays for toxicity (“received dose intensity”) and can be derived for single agent treatments as well as for combinations. In the calculation of dose intensity, treatment delays are assumed to be equivalent to dose reductions and are accorded equal weight arithmetically. Dose intensity correlates very well with outcome for a variety of single agents and drug combinations in various malignant diseases (2).
