  1. AE adverse event, TPC treatment of physician’s choice
  2. aCalculated as dose intensity divided by expected dose intensity; expected dose intensity (mg/m2 per week) equals the assigned dose (mg/m2) divided by planned cycle length (days) times 7
  3. bCalculated as total number of dose reductions or delays due to AE divided by total of number of cycles received
