Matias, Sam Heard will provide an answer to your question in a couple of days - he is currently in the UK after the recent CEN meeting, where apparently WG1 accepted the idea of including the ADL language specification in the standard as a normative part.

Sam will provide a detailed response. - thomas > > Regimen Name: CAF > Step 1: Cyclophosphamide 100 mg/m2/day po days 1-14 > Step 2: Doxorubicin 30 mg/m2/day iv days 1 and 8 > Step 3: 5FU 500 mg/m2/day iv on days 1 and 8 repeat q 4 weeks > > As I see it, there are two possible models: > > 1.
