Thanks so much for the info on calculating mg/m2 and for setting me right about my misconception. The relative doses for your child and mine, now, make much more sense. (See, I was right, wasn't I, about not jumping to conclusions when hearing about somebody else's situation, and making sure that apples are compared to apples, instead of to oranges, like I was apparently doing!!!) I would be quite interested in the articles you mentioned, both in your message to me and in your note to Andy. If you find them and would be willing to e-mail them to me, I can be reached at carolhsu1@juno.com or via fax at 646-924-4234. Thanks so much!
