Mayo Clinic finds insufficient vitamin D levels in CLL patients linked to cancer progression and death


Researchers at Mayo Clinic have found a significant difference in cancer progression and death in chronic lymphocytic leukemia (CLL) patients who had sufficient vitamin D levels in their blood compared to those who didn’t.

In the Mayo Clinic study, published online in the journal Blood, the researchers found that patients with insufficient levels of vitamin D when their leukemia was diagnosed progressed much faster and were about twice as likely to die as were patients with adequate levels of vitamin D.

They also found solid trends: increasing vitamin D levels across patients matched longer survival times and decreasing levels matched shortening intervals between diagnosis and cancer progression.  The association also remained after controlling for other prognostic factors associated with leukemia progression.

The finding is significant in a number of ways.  For the first time, it potentially offers patients with this typically slower growing form of leukemia a way to slow progression, says the study’s lead author, Tait Shanafelt, M.D., a hematologist at Mayo Clinic in Rochester, Minn.

Dr. Shanafelt explains the significance of the study findings below.

    You can thank Big Pharma and dermatologists for your cancer. They promote the sunscare message which reduced your vitamin D levels and left you less healthy.

    I had my blood drawn on 2/24/2011 my WBC was 64.4, I read this article on 3/16/2011. I started taking a 2,000 vitamin D on a daily basis to boost my Vitamin D. I had my blood re-drawn at the doctors request today 4/26/2011 my WBC dropped to 38.3, the nurse asked if I was being treated since they improved so much! Hopefully it will continue to work!

    CAN YOU TELL ME IF I WOULD OR SHOULD GET THE SAME QUALITY VITAMIN D INTAKE FROM A STRAIGHT VITAMIN D CAP AS I WIOULD FROM A VITAMIN D3 CAP?
