How many on Tykerb/Herceptin together?

[Esther]

Are there very many women that are on Tykerb and Herceptin together? I had been on Herceptin from Jan 2004-April 2007 for bc mets.

In April 2007 I switched to Tykerb due to a history of dealing with brain mets, not because the Herceptin was not working.

Ever since I've kept wondering about dropping the Herceptin, thinking I should stay on it as well.

Anyone here on Tykerb and Herceptin at the same time? What has your onc told you about doing this? Are there any reasons why you shouldn't be on them both at the same time?
