CLL is not the only cancer where the blood serum level of vitamin D has been found to correlate with survival time:
Vitamin D May Boost Colon Cancer Survival, Study Finds
'"We found that patients who had vitamin D levels at the highest category had improved survival and improved progression-free survival, compared with patients in the lowest category," said lead author Dr. Kimmie Ng, an assistant professor of medicine at Harvard Medical School in Boston.
Those patients survived one-third longer than patients with low levels of vitamin D -- an average 32.6 months, compared with 24.5 months, the researchers found.
The study only found an association between vitamin D levels and colon cancer survival rates. It did not prove cause and effect.'
Health News Review's take on the article - taking particular issue with the inappropriate title
The recommendations at the end of the parent article hold true for us too:
'Everyone should maintain healthy vitamin D levels anyway, to protect their bone health, Ng and Krishnamurthi said.
Based on this new study, Krishnamurthi said she would emphasize the importance of vitamin D for patients with colon cancer.
"They should take supplements to bring it into normal range, because we know it is good for bone health and it may have an anti-cancer effect," she said.
However, "if someone has a normal vitamin D level, I wouldn't take supplements to increase it because we won't know the true effect on cancer until we see the results of a clinical trial," she said.'
We'll need to wait for the results of the Mayo Clinic vitamin D clinical trial before we'll hopefully know whether higher levels of vitamin D help us live longer or just feed our CLL.
