2018年9月19日 · Ca-15-3 can be used to monitor the response to breast cancer recurrence treatment. However, the results alone cannot be the sole guide to predict the occurrence of metastatic spread. False positive results in raised Ca-15-3 can also be caused by non-cancerous conditions, the list is quite long.

2020年4月12日 · CA-125 = 17.0. CA 27.29 = 32.3. CA 15-3 - 28.9. Per LabCorp (where I had the blood test), the CA 15-3 reading is high or above the 0 to 25 range. The rest were noted as normal. I have severe lower body inflammation (a foot of colon removed in 2013, another surgery needed), varicose vein stripping in 2014 - as both did not go so well.

2012年3月10日 · CA 15-3 does not cause cancer; rather, it is shed by the tumor cells and enters the bloodstream, making it useful as a tumor marker to follow the course of the cancer. CA 15-3 is elevated in about 10% of women with early localized breast cancer and in about 70% of those with metastatic breast cancer.

2013年7月29日 · Well, I have 3 Tumor Markers that are playing up and down : CEA, CA 15-3 and CA 125 and I only have MBC since end 2009... no ovarian cancer. CA 125 was my only marker for a long time....I found that confusing, because I also had found that it is supposed to be an ovarian cancer marker.

2013年10月9日 · CA 15-3 CA 15-3 is mainly used to watch patients with breast cancer. Elevated blood levels are found in less than 10% of patients with early disease and in about 70% of patients with advanced disease. Levels usually drop if treatment is working, but they may go up in the first few weeks after treatment is started.

2021年7月3日 · Newly diagnosed IDC of breast with stage 4 Mets to bone. My oncologist ordered baseline blood work and my CA 15-3 is 140. I’m starting

2020年10月19日 · Allstar, My dr. doesn’t even want to include the CA 15-3 in my monthly blood panels because he feels the test is too unreliable to be meaningful. If yours has been stable for two years, then maybe that value is normal for you. Instead, my doctor prefers to use the breast cancer tumor marker CA 27.29 and the general tumor marker CEA.

2018年6月12日 · CA 15-3 and CA27-29 both recognize MUC1, although each of those recognizes a different region of the protein; both differences that are present in the original non-cancerous cell and changes that occur over time on the cancer cells may make these markers less reliable; also, other markers (CA125 and CEA) May also be present on breast cancer ...

2021年7月29日 · My mother has lobular breast cancer mets to the stomach and bones/bone marrow. She is on fasolodex and Afinitor. Her CEA has been trending down and her CA- 15-3 bounces around. I know I read somewhere on inspire that Afinitor causes an inaccurate reading of the CA-15-3 because it works directly on this tumor pathway.

2020年6月23日 · My CA 27-29 tumor markers were 28 in February and jumped to 42 in June. My oncologist ordered a PET scan which my insurance denied. But my onc is going to do a "peer to peer". My onc did ask if I had recently started taking biotin and I said yes (approximately 13,000mcgs nightly).
