Ca153 as a tumour marker how effective is it

Hi! Cancer Antigen 15-3 is a tumor marker seen in almost 75% of patients with metastasized breast cancer and in only approximately 30% of patients with localized breast cancer. It is most useful in monitoring advanced breast cancer and response to treatment. Most doctors advise CA 15-3 prior to initiating treatment. Once the patient is on therapy serial measurements are done to see the response to treatment. If the values decrease it means response to therapy while increasing levels may suggest progression. Several noncancerous conditions like benign breast or ovarian disease, endometriosis, pelvic inflammatory disease and hepatitis can bring up your levels of CA 15-3. Ovarian, lung and prostate cancers may also produce CA 15-3. It is very important that any test result is correlated clinically. Take care and best luck!

Tumor Markers

Hi, I am not sure about the lyme disease, but I think nit is important that you have a few more tumor marker checks, like 2-4 weeks apart, and to see if they continue to rise. For myself, I find those tests incredibly valuable, and it was the only test about a year ago that convinced my oncologists that indeed, my cancer had come back Best to you, KAT

How effective is the CA 29.30

Hi, You can relax and no need to worry so much. CA27.29 can only be of significance if the values increase markedly from the previous time. Also a progressive rise would be more indicative of a lesion not just a single elevated reading. Also values <100 are rarely associated with malignancy. Hope this helps to calm you. Let us know if you have any other doubts and post us about how you are doing. Good luck.

CA27.29 while on Femara

Hi there. Switching from femara to arimidex may not do much of a difference since bone pains are also a common side effect of arimidex.  Furthermore, these two drugs are of the same class and is not likely to have an effect on the markers.  Faslodex, on the other hand, may be a more reasonable choice. My take on the CA27.29 is that this marker has still of questionnable clinical utility. meaning, elevated levels of this marker does not really translate into the cancer being more aggressive.  It is best to have yourself re-evaluated for other signs of the cancer returning such as CT scans or other imaging studies (PET scan) to see if this elevation in CA 27.29 is indeed significant. Regards.

Blood test for breast cancer

Hi there. As far as present day recommendations are concerned, the testing for this marker is still not routinely recommended for the exact usefullness of this test is still not definite.  For example, in your situation, in the presence of a high level result, your doctors are still not sure on the best way to deal with this result (whether to observe and have the test repeated, or undergo further testing such as X rays or ultrasound of liver). More often, a high result really does not mean anything significant, especially if the repeat tests reveal almost the same levels.  You may have missed out on a smal but significant incremental benefit in survival when you forego with the tamoxifen treatment, but starting it now would still provide some benefit (and this should be discussed with your oncologist). Regards.

Tumor Markers

Hi.  Hematomas should not affect the accuracy and reliability of tumor markers.  However, you are correct in your statement about tumor markers being produced by both benign or malignant tumors. For breast cancer, there is presently no standard recommendations regarding tumor markers (either CA 15-3 or CA 27.29) and it is up to the accepted practices of the specific institutions on how they would interpret or correlate the results of these tests. Regards.
