Colon cancer stage 3b but after surgery CEA level dropped from 13 to 1.8 what does it mean?

Colon cancer stage 3b but after surgery CEA level dropped from 13 to 1.8 what does it mean?

Tumor markers: Cea is a tumor marker it does not occur with all colon cancers but the fact that it dropped so abruptly is a positive sign. The marker has the ability to be used to monitor for recurrence. This does by no means indicates you are done. There are a number of treatments for colon cancer and you should recruit the serviceces of a board certified medical oncologist for an opinion on tx options. ...Read more

Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

My CEA test was a 3. What should I do? I had colon cancer in 1997?

My CEA test was a 3. What should I do? I had colon cancer in 1997?

CEA of 3: is in normal range. IF you have been getting regular checkups yearly and colonoscopies, you don't need to do anything more. Just follow the recommendations for your follow ups and colonoscopies provided by your Oncologist/Colorectal surgeon/gastroenterologist. ...Read more

What do you suggest if my CEA test was a 3. should I do something else . I had colon cancer in 1997?

What do you suggest if my CEA test was a 3. should I do something else . I had colon cancer in 1997?

Chill: Three is normal, my friend. Colon cancer would be unlikely to relapse after 15 years plus. Of course, you could develop another colon cancer so you need to keep your follow ups with your oncologist and get your colonoscopies religiously. Live healthy and if you smoke, quit (that will increase the CEA, by the way). ...Read more

My brother is recovering from colon cancer of 2 years ago. His CEA count has gone from 5.2 to 9.7 to 19.8 in the last 6months. Is there a likelihood that cancer is back?

My brother is recovering from colon cancer of 2 years ago. His CEA count has gone from 5.2 to 9.7 to 19.8 in the last 6months. Is there a likelihood that cancer is back?

Back most likely : With a rise of the cea level well above the normal level, the cancer is back or has spread to other organs or a new primary has formed. His physician/surgeon should immediately start a search for the tumor as some recurrences or new tumors can be removed or treated with chemotherapy. He will need studies such as a chest x-ray, ct of chest, abdomen. & pelvis, colonoscopy and possible pet scan. ...Read more

Are cea markers reliable for metastic colon cancer ?

Are cea markers reliable for metastic colon cancer ?

Depending how used: CEA first identified in 1965 by Phil Gold and Samuel O. Freedman in human colon cancer extracts. Thought to be valuable for dx colorectal Ca but the glycoprotein is also expressed in inflamed tissue so that smoking and enema can cause rise. Best used for monitoring so that if present in primary and rises it represents treatment failure and if diminishes during treatment it represents a response. ...Read more

Disease progression despite the drop in cea - is this possible ? Met colon cancer

Disease progression despite the drop in cea - is this possible ? Met colon cancer

No: The use of tumor markers has been approved for monitoring only. This holds true for the CEA's and Carbohyrate monoclonals such as Ca 19.9 and Ca 125. This is due to the fact that they are also affected by inflammatory changes as well as tumors arising in glandular tissue. If a dx of Ca is well established and the patient is treated with chemo, a drop in tumor marker level means response. ...Read more

Could use your help docs! my CEA test was a 3. Should I do something else? I had colon cancer in 1997?

Could use your help docs! my CEA test was a 3. Should I do something else? I had colon cancer in 1997?

First i would: Repeat the cea, if higher need to discuss with your oncologist or a colorectal surgeon or GI doctor to begin workup of recurrent colon cancer. Cea of 3 is not abnormal. You should have been getting colonoscopies regularly since your original diagnosis. Pet/ct scans may be necessary. But if cea is 3 on repeat i would not be concerned. Just stay on 5year colonoscopy schedule. ...Read more

What can this mean . Before chemotherapy cea was 65, after 1 round 80 and after 2 round 55 for metastic colon cancer ?

Units?: Given that u r from England, the units for the CEA test may be different there. In the US, a level less than 5 ng/mL is "normal". CEA is used as a tumor marker (i.e., colon cancer likely), but (to my knowledge) is not very useful as an indicator of response to treatment. U describe incomplete treatment, anyways. After finishing the rounds of chemotherapy, then check the CEA- that may b useful. ...Read more

What can this cea pattern mean on chemotherapy for colon cancer mets 65 before chemo, 80 after round 1, 55 after round 2?

What can this cea pattern mean on chemotherapy for colon cancer mets
65 before chemo, 80 after round 1, 55 after round 2?

It's improving!: All it really means is the CEA is going in the right direction ... falling after chemotherapy. You can not reliably speculate on what the number changes might say about the magnitude of improvement. There is too much individual variability and unpredictability for that. I would be pleased that these changes have occurred. Best wishes as you continue your treatment:) ...Read more
