I'm sure you read the details of my husband's journey with Glioblastoma, starting with his first surgery 10/28/2019. His second surgery was 2/13/2020 after six months of temodar and radiation treatments, which everyone says is standard treatment. He wore the optune cap and had every other week infusions of Avastin (Bevacizumab) from mid-March through December 2020. His June and Sept. MRI's showed a decrease in his tumor, but the Dec MRI showed it has started growing again. That is what took us to Duke. The folks at Upstate in Syracuse have been wonderful so far, and I am asking our Oncologist to help with determining what is best for the next step---Lomustine or Keytruda. I am trying to read as much as I can to educate myself on the clinical trial results of each to help figure out which to do. It's hard. I wish you all the luck with your current treatment. I will let you know what we decide. Let's stay in touch!!
