    Abstract:
    PURPOSE: Obesity increases mortality for several malignancies, but for non-Hodgkin lymphoma (NHL), the association between body mass index (BMI) and survival is unclear. We examined the association of pre-diagnostic BMI with overall and NHL-specific survival in the multiethnic cohort (MEC) study of African Americans, Native Hawaiians, Japanese Americans, Latinos, and Caucasians. METHODS: MEC participants free of NHL at cohort entry and diagnosed with NHL during follow-up were included in the analyses (n = 1,331). BMI was based on self-reported weight and height at cohort entry and after 6.1 years of cohort entry. Cox proportional hazards regression was used to calculate hazard ratios (HR) and 95 % confidence intervals (CI) with BMI as time-varying exposure in relation to all-cause and NHL-specific mortality while adjusting for known confounders. RESULTS: The mean age at NHL diagnosis was 70.5 (range 45-89) years. After a mean follow-up of 4.3 ± 3.5 years, 667 deaths including 450 NHL-specific deaths occurred. In multivariable models, obese patients (BMI ≥30.0 kg/m(2)) had higher all-cause (HR 1.46, 95 % CI 1.13-1.87) and NHL-specific (HR 1.77, 95 % CI 1.30-2.41) mortality compared with patients with high-normal BMI (22.5-24.9 kg/m(2)). For overweight patients (BMI = 25.0-29.9 kg/m(2)), the respective HRs were 1.21 (95 % CI 0.99-1.49) and 1.36 (95 % CI 1.06-1.75). Cases with low-normal BMI (<22.5 kg/m(2)) experienced a significant 45 % higher all-cause and a 40 % higher NHL-specific mortality. After stratification by NHL type, the adverse effect of BMI was stronger for chronic lymphocytic leukemia/small lymphocytic lymphoma than for diffuse large B cell lymphoma and follicular lymphoma. CONCLUSIONS: Pre-diagnostic BMI may be a suitable prognostic marker for NHL patients.
