Thank you for this insight Cynthia. I am currently trying to get as many different perspectives as possible. It is a good problem to have I guess and I am blessed to be in a position to even consider stopping treatment and just monitoring. So am I right in understanding that your onc is of the opinion that maintenance is the way to go? I wonder at what dose and if it applies to patients who became NED after 2 years as well.

It’s been along time since I’ve been on this site but I read occasionally. As with everyone with this diagnosis or a family member who has colon cancer, it’s been a very tough year.

My mom did not respond well to chemo, in fact it almost killed her. Literally. She landed in the hospital for two weeks after her first round and so her oncologist took chemo off the table. Our only hope was to pray that it didn’t come back. Things were great for about four or five months, but the cancer did come back and this time it was in her peritoneum and deemed in operable. She was terminal and was going downhill rapidly.

I flew out to California in October to be with her and my brother and I were making plans for hospice as it didn’t appear she had much more than a few weeks. We had an appointment with her oncologist and because she is MSI high, he put her on immunotherapy (Keytruda). Within two weeks of her first round she was feeling amazing. Her pain was gone and she was putting weight back on. Three months after starting immunotherapy she had a CT scan and it showed that she had a complete response to the immunotherapy as her tumors were completely gone. She has put on 20 pounds and is as energetic and feeling like she did before she ever had cancer. It has been nothing short of a miracle.

Never ever give up.

Amazing story. Happy for your mom. Yes there is always hope!

I am editing this after thinking about it. I thought if the drug wasn’t working after 2 years that it wasnt going to work. Kind of confused now...

I think that my oncologist meant if there were masses or nodules that were not growing but could still potentially be cancer...or if a person had a CEA that was over 5.0 but not increasing (even if the Keytruda reduced the number fo tumors or reduced the CEA significantly over the 2 years) that he would not suggest stopping the Keytruda.

Updating my own thread:

On my 2nd to the last dose of Keytruda as standard dosing (200mg every 3-4 weeks). I saw my oncologist in Singapore (I have 2 for multiple opinions) and he suggested that I stop treatment completely at the 2 year mark since that’s what he does with his other patients in complete remission and so far the responses have been durable. My main onc prefers to have some sort of treatment for a few more years, although he knows there is no data to support it. He is just more conservative which is good because I kind of get a balance in opinions. Tentatively we have decided that after my last dose next month I will receive a standard dose every 3 months for 1-2 years and depending on the scans during that time we might consider discontinuing the drug completely. I was fine with stopping cold turkey but my wife begged me to choose the 3-month dosing option as a compromise for her peace of mind.

That seems to be the path that I too will follow.

Cynthia...thanks for clarifying that!
Henry and Plastikos....I get that! I think for my own piece of my a “ booster dose” would have calmed me, but ...I was not offered that option!
I must add ...It is a nice problem to have!

I take it your onc would suggest the same option for you to consider? If so, what would be the interval?
