Tamoxifen and Avastin

Does anyone have any experience of having these two drugs together? I started Avastin and Zometa for bone mets half way through my chemo, and will continue for the rest of the year (when the insurance company stops paying for the Avastin). I am a suitable candidate for Tamoxifen, but my onc hasn’t come across anyone combing these drugs yet. She is going to do her own research, but I wondered whether anyone here could help?

Thanks
