length of remissions

Hi all! I was diagnosed stage IV with hip mets, 1 year ago...I began tax,carbo,hercetin chemo which I stayed on until May 2004. I am now NED since May. I am interested in how long people have been able to remain on just herceptin with out a recurrance or spread. I am currently on Herceptin and Zometa. Thanks, Alicia

a year and a half now, one glorious day at a time...........
