FDA Approved Keytruda for MSS Tumors w/ TMB of 10+!!!

Postby Jack&KatiesMommy » Mon Jun 29, 2020 9:20 am

The FDA has approved the immunotherapy Keytruda for solid tumors with a tumor mutation burden of 10 or greater. This means that CRC patients with MSS tumors (with TMB of 10+) are able to get insurance coverage for the use of Keytruda! My oncologist had to petition and appeal to get my insurance to cover Keytruda for me. I have been in it for over 2 years and am a “complete responder.” I am MSS (and all my chemo options were no longer working. I had cancer in lymph nodes near my lungs when I started Keytruda in May 2018). My doctor ordered Foundation One testing and found that I had a TMB of 11....and thought that Keytruda was a final option to try. Today I am cancer free (9 years after initial diagnosis of stage IV colon cancer and lots and lots of chemo and surgeries and rfa’s.

This is great news. My Onc mentioned something about FDA approved something, not sure if it was Keytruda, but will talk to him. My TMB is 8, but I want him to do a new test from my last surgery, will talk to him about it.

So when you say your Cancer free, are you not doing any regimen at the moment? I hope this is the case and truly happy for you!!

Hi Riki:
I would definitely get your TMB checked again. My oncologist thinks that mne was so high due to to the prior 7 years of treatment I had gone through (multile years of chemo, rfa's etc.)

An I am currently still getting immunotherapy...but there is no evidence of disease. The immuntherapy worked...but there is no guidance as to when it is safe to stop and I am not ready to be the person to "give it a shot." It is an infusion every 3 weeks with very few side effects (fatigue ony for me).

Cynthia,

That is awesome news. Very happy things are working and your here for a long time to enjoy your beautiful family. So the side effects Fatigue is nothing like being on FolFIRI? not even close right? How long does the fatigue last for? That CEA at .8 is the most wonderful number. I was there from my first surgery after I was 600+ CEA, love the .8 CEA.
