No association between vitamin A, C, D, E and lycopene and risk of non-Hodgkin lymphoma

Objectives:
There has been accumulating evidence that several micronutrients may play a protective role in the risk of solid cancers. However, their role in hematological malignancies remains to be elucidated. Therefore, this review article has been conducted.

Is there a relationship between vitamin intake and risk of non-Hodgkin lymphoma?

Study design:
This review article included a total of 12 cohort studies.

Results and conclusions:
The investigators found null associations regarding
-supplemented vitamin A [pooled RR = 0.92, 95% CI = 0.80-1.07];
-supplemented vitamin C [pooled RR = 1.00, 95% CI = 0.90-1.12];
-total vitamin D [pooled RR = 1.05, 95% CI = 0.91-1.20];
-supplemented vitamin E [pooled RR = 0.98, 95% CI = 0.88-1.10] and;
-dietary lycopene intake [pooled RR = 1.00, 95% CI = 0.86-1.16] and risk of non-Hodgkin lymphoma.

The investigators found no summary estimates were provided for other hematological malignancies due to the limited number of studies.

The investigators concluded there is no association between vitamin A, C, D, E and lycopene and risk of non-Hodgkin lymphoma.
