Stage IV lung cancer, what treatments work for you?

That is great news. What is HER2 amplification and Erbb2 mutation.

All-- There is of course a ton of interest in bio-markers and immunotherapy and the testing that goes with it. Since I know next to nothing about this topic, mainly because I've never had any suggestion that I might be able to have any. Nevertheless since this wonderful science is now available to so many people with lung cancer I do need to learn more. I found this site and hope to be able to learn more. Do any of you have experience enough to simply explain immunology, beyond the simple fact that it uses your own body to help fight cancer?

@schmeeckle64- Good morning and Welcome to Connect. I am a Mentor for Mayo Connect and would like to join everyone in welcoming you. I have had lung cancer (Multifocal Adenocarcinoma of the lungs) since 1997 and my last one was 2 years ago, this fall. It is a NSCLC. I've had a lot of different treatments but have never had immunotherapy. I don't know if I'm eligible but I don't think so. I am so glad that you are responding to Keytruda. How are you feeling?

Hi Christie, I was diagnosed with stage 4 squamous lung cancer in June of 2015. I did anything and everything the doctors told me to do and tried not to listen to all "cures" everyone else told me about! I have been in total remission for over 2.5 years now. Good luck in your battle and stay strong.

Hi Merry! Thank you for reaching out. I am feeling really really good. Will be on round 7 of Keytruda next week. So far I have had no side effects. The past couple weeks my mouth has been really dry so I have been trying different things to help with that. Go in for a scan in July and that is freaking me out a little, but prayers help calm me down. What types of treatments have you had?

@schmeeckle64- Good morning. I know, I know, and you have tons of company. The thing is that these aren't just a routine test, like a yearly blood work test, but a test that literally can tell us if we are going to live for another 3 or 6 or 12 months or die.:

I have written a blog that you might be interested in reading about my journey with lung cancer:

My next CT scan is in July too and I am a basket case about 2 weeks out. Sometimes I have any easier time with good feelings and others not so much. I try and stay busy with mind occupying activities. But they don't work a lot of the time.

What have you found to keep you busy? Do you work?
