Re: Intrathecal (IT) Herceptin (Trastuzumab) for brain mets (Leptomeningeal Metastase
Hello,
I was just coming to look for this thread, and here it is front and center. I could use some help!
With a previously treated brain metastasis possibly growing ( unknown if its growth or necrosis) on my latest MRI's, plus a new 9 mm spot very close to it, I am trying to figure out how best to proceed with treatment. I have had stereotactic radio surgery- once to this older spot, and once to another spot that has shrunk.
I mentioned IT Herceptin to my Oncologist, who was very open minded about it. It has not been done in my treatment facility, and he has many questions about it. Is there a doctor who would answer his questions such as dosage, and pre-meds, side-effects, etc.? Or should I seek out going somewhere for treatment? I live on the border of North Dakota and Minnesota, and have had great treatment here so far.
For now they have referred me to a Neurosurgeon for a consult, but I am open to suggestions, any help you can offer. Thank you!!
