Objective: To evaluate the associations between diet and non-Hodgkin lymphoma (NHL) according to t(14;18) status, one of the most common chromosomal abnormalities in NHL, as t(14;18)-positive NHL represents a genetically more homogeneous group than NHL overall. Methods: We determined the presence of the t(14;18)(q32;q21) by fluorescence in situ hybridization in 172 of 175 tumor blocks from a population-based, case-control study conducted in Nebraska during 1983-1986. Information on the frequency of consumption as an adult of 30 food items was derived from the parent case-control study. Dietary factors in 60 t(14;18)-positive and 87 t(14;18)-negative cases were compared with 1,075 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using polytomous logistic regression. Results: The risk of t(14;18)-positive NHL for the highest versus the lowest approximate tertile of intake was elevated for milk (OR = 2.2; 1.0-5.0) and dietary nitrite (OR = 2.8; 1.3-6.1), whereas coffee consumption was inversely associated with risk (OR = 0.4; 0.2-0.7). We also found inverse associations between the intake of fish (OR = 0.5; 0.3-1.0) and carotene (OR = 0.5; 0.2-0.9) and risk of t(14;18)-negative NHL. There was no association between the intake of meats, vegetables, protein, or vitamin C and risk of either t(14;18)-positive or t(14;18)-negative NHL. Conclusion: We observed differences in associations between diet and t(14;18)-defined subgroups of NHL. These findings should be interpreted cautiously because of the small sample.
