Re: Intrathecal (IT) Herceptin (Trastuzumab) for brain mets (Leptomeningeal Metastase
Vicky leptomeningeal metastases are those that sit on the outer linings of the brain and spinal cord. Cerebrospinal fluid circulates within those membranes.
If your brain mets are not near the outer (or inner) linings of the brain, it is unlikely IT herceptin can get to them as I understand it.
Please be certain to clarify where your brain mets are and how far from the CSF they may lie.
