— A shortage of vitamin D may stack
the deck against people fighting a common
form of lymphoma, researchers reported December
5 at a meeting of the American Society of
Hematology. The new study adds this cancer
to the list of malignancies suspected of
being more difficult to control in patients
with vitamin D deficiency common in parts
of the U.S. population.
to 2008, the researchers analyzed blood
samples from 374 newly diagnosed patients
with diffuse large B-cell lymphoma, a fast-growing
cancer of white blood cells called B cells.
It mainly hits people over 50 and accounts
for roughly 40 percent of lymphomas.
participants averaged 62 years of age. The
blood tests revealed that half were deficient
in vitamin D at the start of treatment,
having less than 25 nanograms per milliliter
monitored the patients for an average of
three years. During the follow-up,
patients who were deficient in vitamin D
were twice as likely to die, compared
with patients who had adequate vitamin D
blood levels at the outset. Patients with
low vitamin D concentrations were also about
50 percent more likely than the others to
have their cancer worsen, says endocrinologist
Matthew Drake of the Mayo Clinic in Rochester,
Minn., who presented the findings.
