I’m stage 4 as well but discovered a high dose radiation treatment (NOT the same as SBRT that most oncologist know about) at Memorial Sloan Kettering in NYC. It was 3 full weeks/5 days a week. I was able to be off chemo for 6 mos. Some people have gone considerably longer. There are very few places that do this method and Dr. Christopher Crane at MSK pioneered it so I went there. Maybe worth looking into for your situation. He’s very good at getting back to you and explaining the procedure. And we were set up at Hope Lodge and stayed for free.
