Hello fighters! As I'm reading this discussion about keytruda I felt compelled to share my keytruda story. In May of 2017 three months before my husband died of leukemia I was diagnosed with stage 4 lung cancer that had spread to my adrenal gland. I went to Houston Methodist in the medical center. They put me in a trial which involved inserting a fissure into the tumor on my lung. They gave me pinpoint radiation and loaded up the fissure. The fissure destroyed the tumor and then traveled to the tumor on my adrenal gland and embedded itself into that tumor and destroyed it as well. This process on me only took a few months, no side effects. Then they started my keytruda treatments. I got a keytruda rash twice and they had to stop treatment early due to colitis. This is 2024 and I'm alive! There is hope out there for you! I suggest you get ahold of Houston Methodist in the medical center and ask about their trials for lung cancer. I would give you the name of my oncologist but unfortunately he moved to Colorado. I do know you have to have certain markers etc to do this, I don't know all the details. I do know I qualified because I hadn't had any previous treatments. I don't think, just my opinion that just keytruda on its own is going to help you. I hope this information is helpful to just one person out there. If it is please let me know and I will share this information on other websites as well. Keep up the fight my fellow fighters!
