Re: Stage IV and Metastatic members-do you have weekly or every three week treatments
Caroline, I am also on a 3 week schedule.
Here is the U.S. FDA Herceptin label, maybe there is one for your country too?
http://www.accessdata.fda.gov/drugsa...92s5250lbl.pdf
There are four dosing scenarios. It actually says for metastatic breast cancer to administer a 4 mg/kg loading dose then 2 mg/kg weekly.
If this is on the FDA label, there must be studies to back it up. I searched a little but didn't find the studies. I'll bet if you call Genentech they can tell you.
Love,
Rachael
