Figure 3. Chemotherapy doses stratified by in-hospital survival status.
Induction-consolidation was scheduled at six weekly intervals of intravenous (A) cyclophosphamide (1200mg/m2) and (B) vincristine (1.5mg/m2); 4 weekly interval doses of intrathecal (C) methotrexate (7.5mg/m2); and (D) doxorubicin (60mg/m2) on days 1 and 22. Chemotherapy dosage status was defined by determining recommended doses based on retrospectively re-calculated BSA and comparing to dose of drugs received. Children who inadvertently received >115% of the recommended dose for a chemotherapy drug based on their re-calculated BSA were classified as overdosed, while children who received <85% of the recommended dose were classified as underdosed. Children who received doses within 15% of that recommended for their BSA were classified as correctly dosed.
