In need of data about Her2 recurrence

[Val Pfeiffer]

Do any of you know where I can find data regarding where mets are likely to occur in Her2 breast cancer patients? Specifically, if a woman with non-stage 4 Her2 breast cancer later has a stage 4 recurrence, where is it likely to occur? I am looking for something like this (of course these numbers are made up):

Lungs 26% of the cases
Bone 30% of the cases
Brain 41% of the cases
Liver 40% of the cases

(these will probably not add up to 100% since recurrences sometimes happen in more than one place)

thanks :-)
