Weekly versus 3 week Herceptin dose studies

Hi all,

I'm writing on behalf of my sister-in-law who is located in Germany and has Her2-neu BC. she's on chemo right now, her onc started giving her Herceptin (and for the ones that don't know it - the Herceptin is now also allowed for bc without metastases - thank goodness) with taxotere. I'm still trying to find out all the details - darn time difference drives me crazy besides the point that I can barely talk to her because she's not feeling too well. Her leukos went down to 1700, I believe when they reach 1000 she'll get hospitalized.

I'm curious about your experiences with the Herceptin and the taxotere (and no - I have not found out yet whether she receives the weekly or 3 week dosis, like I said - her first treatment was July 13th and ever since can't get in touch with anyone over there). She's feeling very weak, bone pain, and gets morphium against the bone pain. What I don't understand and my brother emailed me - the pain and the low leukos may be due to the taxotere which she receives in 4 "units". I don't understand it but he didn't elaborate either. Any clues??
