Low vitamin D linked to worse prognosis in type of non-Hodgkin lymphoma

But remember that too much vitamin D is toxic.

A new study found that people with lower vitamin D levels prior to treatment for follicular lymphoma succumb to the disease or face relapse earlier than patients with sufficient vitamin D levels in their blood.

The Wilmot Cancer Institute investigation is believed to be the first to report that lack of vitamin D is a potentially modifiable risk factor for this type of cancer. The study was published by the Journal of Clinical Oncology.

Vitamin D's connection to cancer is an active research topic. Prior studies have shown a survival benefit among patients with higher vitamin D levels for diffuse large B-cell lymphoma and chronic lymphocytic leukemia. In addition, earlier peer-reviewed research at Wilmot showed that low vitamin D levels among women with breast cancer correlated with more aggressive tumors and poorer prognosis; and that vitamin D deficiency among African Americans might help to explain higher death rates from colorectal cancer. Currently, Wilmot investigators are evaluating whether weekly, high doses of vitamin D (50,000 IU) improves the side effects related to androgen deprivation therapy for prostate cancer in patients ages 65 and older.
