Vitamin D levels may play role in beating lymphoma

The results of a study carried out at the Mayo Clinic and presented at the meeting of the American Society of Hematology (ASH) suggest that vitamin D levels influence patient survival following standard treatment for diffuse large b-cell lymphoma (DLBCL).

Researchers monitored blood samples taken from 374 patients with previously untreated DLBCL who then underwent treatment involving chemotherapy and discovered that, three years on, patients with a vitamin D deficiency were twice as likely to succomb to their disease as those with sufficient levels in their blood (a vitamin D deficiency was defined in this study as having begun treatment with under 25 nanograms of vitamin D per milliliter of blood).

Researchers were cautious not to make a direct link between vitamin D and lymphoma, and critics of the study noted the lack of controls.

DLBCL is the most common form of non-Hodgkin's lymphoma, accounting for four of every ten new NHL diagnoses. Patients are typically over age 50.
