@sc1218, welcome to Connect. You'll notice that I moved your message to this existing discussion about Keytruda and colon cancer. I did this so you can meet @brenz whose husband is also receiving or considering Keytruda treatments for colorectal cancer. Brenz, did he start Keytruda?

Have you had any treatments prior to starting Keytruda? What type and stage is your cancer?

i was on the test drug Immunotherapy, not sure what name it was. I have stage 4 Colin, which went to liver, prior to any Colin surgery they wanted me on chemo prior to surgery based on amount of cancer in liver. I noticed big reduction in size of the tumors in the liver, uncertain if it did any reduction in Colin, but i ended up having 3 stents inserted prior to Colin surgery. There was over 50% in sizes of tumors in liver. Since i am back on chemo again, i would like to get back on Immunotherapy, but there saying they aren't taking any new patients in right now. Good luck with yours 👍
