caveat--most of the intrathecal herceptin articles are for
leptomeningeal carcinomatosis ie mets on the lining of the outside of the brain
where the CNS fluid can get to them. BBB is feltto be within the meninges so it
may be unclear whether the herceptin can get to the "too numerous to count"
mets which I suppose are within the substance of the brain rather than its outside coverings.
That is why I didn't post these first, but perhaps it will get the oncologists to put their thinking caps on...
