ABSTRACT Prospective studies of lifestyle and non-Hodgkin lymphoma (NHL) are conflicting, and some are inconsistent with case-control studies. The Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial was used to evaluate risk of NHL and its subtypes in association with anthropometric factors, smoking, and alcohol consumption in a prospective cohort study. Lifestyle was assessed via questionnaire among 142,982 male and female participants aged 55-74 years enrolled in the PLCO Trial during 1993-2001. Hazard ratios and 95% confidence intervals were calculated using Cox proportional hazards regression. During 1,201,074 person-years of follow-up through 2006, 1,264 histologically confirmed NHL cases were identified. Higher body mass index (BMI; weight (kg)/height (m)(2)) at ages 20 and 50 years and at baseline was associated with increased NHL risk (P(trend) < 0.01 for all; e.g., for baseline BMI > or =30 vs. 18.5-24.9, hazard ratio = 1.32, 95% confidence interval: 1.13, 1.54). Smoking was not associated with NHL overall but was inversely associated with follicular lymphoma (ever smoking vs. never: hazard ratio = 0.62, 95% confidence interval: 0.45, 0.85). Alcohol consumption was unrelated to NHL (drinks/week: P(trend) = 0.187). These data support previous studies suggesting that BMI is positively associated with NHL, show an inverse association between smoking and follicular lymphoma (perhaps due to residual confounding), and do not support a causal association between alcohol and NHL.

A total of 5694 patients with MM were included, among whom 1584 (28%) were from the UK Million Women Study (Kroll et al., 2012) and 1567 (28%) were from the recent pooled analysis in the 'International Multiple Myeloma Consortium' (Andreotti et al., 2013).

    ABSTRACT: The role of alcohol intake in the risk for multiple myeloma (MM) is unclear, although some recent findings suggest an inverse relationship. To summarize the information on the topic, we carried out a systematic review and a dose-risk meta-analysis of published data. Through the literature search until August 2013, we identified 18 studies, eight case-control and 10 cohort studies, carried out in a total of 5694 MM patients. We derived pooled meta-analytic estimates using random-effects models, taking into account the correlation between estimates, and we carried out a dose-risk analysis using a class of nonlinear random-effects meta-regression models. The relative risk for alcohol drinkers versus non/occasional drinkers was 0.97 [95% confidence interval (CI), 0.85-1.10] overall, 0.96 (95% CI, 0.74-1.24) among case-control studies, and 1.00 (95% CI, 0.89-1.13) among cohort studies. Compared with nondrinkers, the pooled relative risks were 0.96 (95% CI, 0.81-1.13) for light (i.e. ≤1 drink/day) and 0.89 (95% CI, 0.74-1.07) for moderate-to-heavy (i.e. >1 drink/day) alcohol drinkers. The dose-risk analysis revealed a model-based MM risk reduction of about 15% at two to four drinks/day (i.e. 25-50 g of ethanol). The present meta-analysis of published data found no strong association between alcohol drinking and MM risk, although a modest favorable effect emerged for moderate-to-heavy alcohol drinkers.

    • "Studies conducted in Connecticut and among women living in Iowa, for instance, have suggested decreased risks of NHL associated with higher consumption of red wine [33] [44]. Higher consumption of wine has also been inversely associated with NHL in a large population-based case-control study [45], but other studies suggest null or elevated risks [10] [20] [40]. Red wine is a source of a variety of phytochemicals, including resveratrol which has antiinflammatory properties and may aid in the inhibition of tumor proliferation [46], including for human lymphoma cells specifically [47].

    ABSTRACT: The incidence rates of non-Hodgkin lymphoma (NHL) have steadily increased over the last several decades in the United States, and the temporal trends in incidence can only be partially explained by the HIV epidemic. In 1992, an international workshop sponsored by the United States National Cancer Institute concluded that there was an "emerging epidemic" of NHL and emphasized the need to investigate the factors responsible for the increasing incidence of this disease. Over the past two decades, numerous epidemiological studies have examined the risk factors for NHL, particularly for putative environmental and lifestyle risk factors, and international consortia have been established in order to investigate rare exposures and NHL subtype-specific associations. While few consistent risk factors for NHL aside from immunosuppression and certain infectious agents have emerged, suggestive associations with several lifestyle and environmental factors have been reported in epidemiologic studies. Further, increasing evidence has suggested that the effects of these and other exposures may be limited to or stronger for particular NHL subtypes. This paper examines the progress that has been made over the last twenty years in elucidating the etiology of NHL, with a primary emphasis on lifestyle factors and environmental exposures.
