Re: Intrathecal (IT) Herceptin (Trastuzumab) for brain mets (Leptomeningeal Metastase
Here are some questions that aren't addressed here:
Has anyone who has had IT Herceptin treatment ever stopped it due to presumed disease eradication?
In the absence of tests confirming disease advancement, has IT therapy ever been done to prevent disease progression in previously treated HER2 brain mets patients?
What are the worst side effects seen with IT Herceptin? Have patients had to stop being treated due to issues?
