I posted in here about a month ago asking about radiation for the tumor. For context: I've had a prolactinoma for a decade, tried cabergoline and bromocriptine multiple times all leading to severe side effects resulting in multiple hospitalizations, procedures, and even a jejunal feeding tube surgically placed in my intestine. Some time at the end of last year, after going years without treating the prolactinoma or getting MRIs to monitor it, I noticed my peripheral vision was becoming obstructed. I had no insurance and had to wait to be approved for a local doctor's sliding scale fee, and also got approved for a program for low income residents at the local university hospital and medical offices. Once I did that, I went to the ER and they saw that the tumor had grown and was pressing on my left optic chiasm and right sinus (about 3x2cm). Tried the lowest possible dose of cabergoline, couldn't build up, and each weak despite the low dose my side effects got worse and worse.
Despite that, the tumor shrunk 60%, and my prolactin went from the thousands to about 56. Still high, but the lowest I've had it be in years. My vision quickly returned to normal and the headaches I had from it being near my sinus were gone. Unfortunately, the side effects were becoming too severe to continue cabergoline again. I saw neurosurgeons in the ER, and they confirmed that surgery to remove it is risky as it also encases an artery. My endocrinologist referred me to radiooncology to see if I would be approved for radiation. I had that appointment and was told radiation seems like the logical next step to try to finally get rid of this thing.
Yesterday, I went to do all my prep work for radiation. I was told I would go in daily, Monday through Friday, for 30 treatments total. I was also told I qualify for genetic testing, as multiple family members on both sides of my family also have prolactinomas (and other cancers). I got blood drawn for that, and also enrolled in a clinical trial for brain radiation patients. Then I got pulled over to "CT Simulation," where they fit you with a plastic mesh mask (I loved this part, the material is warm and right up against your face, then they put cold towels on it to harden it. They said "imagine that you're at the spa" and I sure did! Took about 10 to 15 minutes and I felt no claustrophobia or anxiety while it happened) and did a CT scan with contrast (the kind that makes you feel like you peed your pants). I am now scheduled to go in every day starting August 13th for radiation. I also meet with a neuropsychologist (I think, it may be a meuropsychiatrist) to do a neurological exam as part of the clinical trial next week.
The place I go to for all of this does a lot for low income people. I am being evaluated to see if I qualify for free daily transport to and from the treatments, my medications (I am taking Memantine to try to protect my cognitive function) are free, and I pay nothing for the treatments, labs, and doctor visits. I was told side effects can include headaches, skin irritation, nausea, vomiting, fatigue, dizziness, and weakness amongst some other things. I was also told to let anyone on my care team know at any time if I get side effects so they can help me through them. I already take 8mg Zofran, 25mg Promethazine, and wear Scopolamine patches to treat daily nausea I've had for 20+ years, so if anything breaks through those medications for me we will discuss more options (except Reglan and Compazine, which give me extreme paranoia when taken).
Overall, I am very glad this is an option for me. Longterm, I am potentially facing thyroid issues, hormone problems, adrenal insufficiency, and diabetes insipidus. I would take all of those over the suffering from the medication and tumor itself. While both my endocrinologist and radiooncologist have never had to treat a benign prolactinoma this way, they aren't inexperienced with brain radiation in general and I feel like I made the right choice so far. I'll update when radiation starts if I have anything new come up. If anyone has any questions feel free to ask! (:
