Elevated CEA and low GFR

Posted by twin71 @twin71, Mar 22 8:23am

I am a stage IV colon cancer survivor, in remission 3 years and 9 months. My CEA has been elevated for the past year and my GFR has been low. I know both of these have to do with the kidneys. Has anyone experienced this? I only drink coffee in the morning and water throughout the day.

Interested in more discussions like this? Go to the Colorectal Cancer Support Group.

My autocorrect changed the wording on me. It’s elevated creative and low GFR levels that I am wondering about.

@twin71, CEA is a protein marker that can be elevated in some cancers, like colorectal cancer, while creatinine is a waste product of muscle metabolism that indicates kidney function. Elevated creatinine levels and a low glomerular filtration rate (GFR) often indicate reduced kidney function, potentially suggesting kidney disease or kidney failure, but can also be caused by other factors.

Have you had a chance to talk to your doctor for further clarification? Is cancer treatment affecting your kidneys negatively?

I’ve been done with treatment soon to be 4 years and it’s never been a concern but looking at my labs I see the high and low of those two and now worried. I meet with my oncologist next month so definitely will question. I am incontinent from my colon surgeries so I don’t know if that plays into as well.
