[PMID: 20949561 PMCID: PMC3125462 DOI: 10.1002/ijc.25717] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2010] [Accepted: 09/03/2010] [Indexed: 12/24/2022]
Abstract
The t(14;18) chromosomal translocation is the most common cytogenetic abnormality in non-Hodgkin lymphoma (NHL), occurring in 70-90% of follicular lymphomas (FL) and 30-50% of diffuse large B-cell lymphomas (DLBCL). Previous t(14;18)-NHL studies have not evaluated risk factors for NHL defined by both t(14;18) status and histology. In this population-based case-control study, t(14;18) status was determined in DLBCL cases using fluorescence in situ hybridization on paraffin-embedded tumor sections. Polytomous logistic regression was used to evaluate the association between a wide variety of exposures and t(14;18)-positive (N=109) and -negative DLBCL (N=125) and FL (N=318), adjusting for sex, age, race, and study center. Taller height, more lifetime surgeries, and PCB180 exposure were associated with t(14;18)-positivity. Taller individuals (third tertile vs. first tertile) had elevated risks of t(14;18)-positive DLBCL (odds ratio [OR] = 1.8, 95% confidence interval [CI] 1.1-3.0) and FL (OR=1.4, 95%CI 1.0-1.9) but not t(14;18)-negative DLBCL. Similar patterns were seen for individuals with more lifetime surgeries (13+ vs. 0-12 surgeries; t(14;18)-positive DLBCL OR=1.4, 95%CI 0.7-2.7; FL OR=1.6, 95%CI 1.1-2.5) and individuals exposed to PCB180 greater than 20.8 ng/g (t(14;18)-positive DLBCL OR=1.3, 95%CI 0.6-2.9; FL OR=1.7, 95%CI 1.0-2.8). In contrast, termite treatment and high alpha-chlordane levels were associated with t(14;18)-negative DLBCL only, suggesting that these exposures do not act through t(14;18). Our findings suggest that putative associations between NHL and height, surgeries, and PCB180 may be t(14;18)-mediated and provide support for case-subtyping based on molecular and histologic subtypes. Future efforts should focus on pooling data to confirm and extend previous research on risk factors for t(14;18)-NHL subtypes.

Abstract
Several previous studies found inverse associations between alcohol consumption and risk of non-Hodgkin lymphoma (NHL) and multiple myeloma. However, most studies were retrospective, and few distinguished former drinkers or infrequent drinkers from consistent nondrinkers. Therefore, the authors investigated whether history of alcohol drinking affected risks of NHL and multiple myeloma among 102,721 eligible women in the California Teachers Study, a prospective cohort study in which 496 women were diagnosed with B-cell NHL and 101 were diagnosed with multiple myeloma between 1995-1996 and December 31, 2007. Incidence rate ratios and 95% confidence intervals were estimated using Cox proportional hazards regression. Risk of all types of B-cell NHL combined or multiple myeloma was not associated with self-reported past consumption of alcohol, beer, wine, or liquor at ages 18-22 years, at ages 30-35 years, or during the year before baseline. NHL subtypes were inconsistently associated with alcohol intake. However, women who were former alcohol drinkers at baseline were at elevated risk of overall B-cell NHL (rate ratio = 1.46, 95% confidence interval: 1.08, 1.97) and follicular lymphoma (rate ratio = 1.81, 95% confidence interval: 1.00, 3.28). The higher risk among former drinkers emphasizes the importance of classifying both current and past alcohol consumption and suggests that factors related to quitting drinking, rather than alcohol itself, may increase B-cell NHL risk.

Abstract
Background: Hepatitis C virus (HCV) infection is associated with an increased risk of primary liver cancer; however, 5- and 10-year risk estimates are needed. The association of HCV with non-Hodgkin lymphoma (NHL) is uncertain and the association with other cancers is unknown. Method: We conducted a nationwide, population-based cohort study of 4,349 HCV-infected patients in Denmark, computing standardized incidence ratios (SIR) of cancer incidence in HCV infected patients compared with cancer incidence of the general population. We calculated 5- and 10-year risks of developing cancer, stratifying our analyses based on the presence of HIV coinfection and cirrhosis. Results: We recorded an increased risk of primary liver cancer (SIR: 76.63 [95% CI: 51.69–109.40]), NHL (SIR: 1.89 [95% CI: 0.39–5.52]), and several smoking- and alcohol-related cancers in HCV infected patients without HIV coinfection. HCV-infected patients without HIV coinfection had a 6.3% (95% CI: 4.6%–8.7%) risk of developing cancer and 2.0% (95% CI: 1.1%–3.8%) risk of developing primary liver cancer within 10 years. Conclusion: We confirmed the association of HCV infection with primary liver cancer and NHL. We also observed an association between HCV infection and alcohol- and smoking-related cancers.

Abstract
BACKGROUND Smoking, alcohol use, and obesity appear to increase the risk of developing non-Hodgkin lymphoma (NHL), but to the authors' knowledge, few studies to date have assessed their impact on NHL prognosis. METHODS The association between prediagnosis cigarette smoking, alcohol use, and body mass index (BMI) and overall survival was evaluated in 1286 patients enrolled through population-based registries in the United States from 1998 through 2000. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated using Cox regression, adjusting for clinical and demographic factors. RESULTS Through 2007, 442 patients had died (34%), and the median follow-up for surviving patients was 7.7 years. Compared with never smokers, former (HR, 1.59; 95% CI, 1.12-2.26) and current (HR, 1.50; 95% CI, 0.97-2.29) smokers had poorer survival, and poorer survival was found to be positively associated with smoking duration, number of cigarettes smoked per day, pack-years of smoking, and shorter time since quitting (all P <0.01). Alcohol use was associated with poorer survival (P = 0.03); compared with nonusers. Those drinking >43.1 g/week (median intake among drinkers) had poorer survival (HR, 1.55; 95% CI, 1.06-2.27), whereas those drinkers consuming less than this amount demonstrated no survival disadvantage (HR, 1.13; 95% CI, 0.75-1.71). Greater BMI was associated with poorer survival (P = 0.046), but the survival disadvantage was only noted among obese individuals (HR, 1.32 for BMI > or = 30 vs BMI 20-24.9; 95% CI, 1.02-1.70). These results held for lymphoma-specific survival and were broadly similar for diffuse large B-cell lymphoma and follicular lymphoma. CONCLUSIONS NHL patients who smoked, consumed alcohol, or were obese before diagnosis were found to have a poorer overall and lymphoma-specific survival.

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.

Abstract
OBJECTIVES To investigate potential risk factors (personal characteristics, lifestyle, and environmental factors) of non-Hodgkin lymphoid neoplasms (NHLN), including lymphomas and lymphocytic leukemia, according to the World Health Organization classification. MATERIALS AND METHODS The investigation was a hospital-based case-control study consisting of 649 confirmed NHLN cases and 1298 individually gender-age-matched patient controls at 25 hospitals in Shanghai. A 17-page questionnaire was used to obtain information on demographics, medical history, family history, lifestyle risk factors, employment history, residential history, and occupational and non-occupational exposures. Risk estimates were calculated using conditional logistic regression models. RESULTS Potential risk factors of NHLN (all subtypes combined) or individual subtypes included low-level education, home or workplace renovation, living on a farm, planting crops, and raising livestock or animals. Some risk factors applied to all or most subtypes (such as lowlevel education, living on a farm, and raising livestock or animals), whereas others did not (such as the use of traditional Chinese medicines, which was associated with a reduced risk). Blood transfusions, hair dyes, or living near high-voltage power lines were not associated with an increased risk. CONCLUSIONS The study identified a number of risk factors for NHLN overall and specific subtypes. Some risk factors were subtype-specific. The difference in risk by subtype underscores the etiologic commonality and heterogeneity of NHLN subtypes.

Abstract
OBJECTIVE We re-evaluated reported associations between tobacco use and other factors and non-Hodgkin lymphoma (NHL) t(14; 18)-subtypes based on fluorescence in situ hybridization (FISH) assays believed to be more sensitive than polymerase chain reaction (PCR), previously used for detecting t(14; 18). METHODS Commercial FISH assays and bcl-2 immunostaining were performed on paraffin sections to determine t(14; 18) and bcl-2 case-subtypes. Polytomous logistic regression models estimated associations between NHL case-subtypes (versus 1,245 population-based controls) and tobacco use as well as other factors. RESULTS Adjusting for age, state, and proxy status, t(14; 18)-negative NHL was associated with any tobacco use (vs. no tobacco use, OR = 1.9, 95% CI = 1.0-3.5), including current smoking (vs. no cigarette use, OR = 1.9, 95% CI = 1.1-3.2). Tobacco exposures were not clearly associated with t(14; 18)-positive NHL or bcl-2 case-subtypes. Hair-dye use and family history of a hemolymphatic cancer were associated with t(14; 18)-negative NHL, but the number of exposed cases was small. CONCLUSIONS The association between t(14; 18)-negative NHL and cigarette smoking was unexpected given previous evidence of associations between smoking and follicular lymphoma (which is largely t(14; 18)-positive). Future studies characterizing additional molecular characteristics of t(14; 18)-negative NHL may help determine whether the association with smoking may have been causal versus an artifact of chance or bias.

Abstract
The aim of this study was to investigate whether genetic polymorphisms in cytochrome P450s (CYPs), glutathione S-transferases (GSTs), and N-acetyltransferases (NATs) genes modify the relationship between alcohol consumption and risk of non-Hodgkin's lymphoma (NHL) in a population-based, case-control study including 1,115 Connecticut women. Although we did not find strong evidence that the genetic polymorphisms modify the relationship between alcohol consumption and risk of NHL, we identified significant interactions for multiple GSTs and NATs and alcohol intake among persons with DLBCL. Our results confer support investigation of the gene-environment interaction in a larger study population of DLBCL.

Abstract
Few studies have evaluated the association between alcohol intake and the risk of the lymphoid neoplasms malignant lymphoma (ML) and plasma cell myeloma (PCM) among Asian populations. We conducted a large-scale population-based cohort study of 95,520 Japanese subjects (45,453 men and 50,067 women; age 40-69 years at baseline) with an average 13 years of follow-up, during which a total of 257 cases of ML and 89 of PCM were identified. Hazard ratios and 95% confidence intervals were estimated using a Cox regression model adjusted for potential confounders. Alcohol intake of > or = 300 g/week was associated with a significantly lower risk of lymphoid neoplasms (hazard ratio, 0.60; 95% confidence interval, 0.37-0.98) than occasional drinking at a frequency of <1 day/month, and the trend for alcohol consumption was significant (P = 0.028). A similar trend was observed for the subcategories of ML, PCM, and non-Hodgkin lymphoma (NHL), albeit that the results were significant only for alcohol consumption at > or = 300 g/week in NHL patients, probably due to the small number of subjects in each category. In conclusion, we found that alcohol had an inverse association with the risk of lymphoid neoplasms, particularly the risk of NHL, among a Japanese population.

Abstract
INTRODUCTION Epidemiological studies have shown that moderate alcohol drinkers have a lower death rate for all causes. Alcohol drinking has also been associated with reduced risk of non-Hodgkin lymphoma (NHL). Here, we examined the role of alcohol consumption on NHL survival by type of alcohol consumed and NHL subtype. METHODS A cohort of 575 female NHL incident cases diagnosed during 1996-2000 in Connecticut was followed-up for a median of 7.75 years. Demographic, clinical, and lifestyle information was collected at diagnosis. Survival analyses were conducted with Kaplan-Meier methods, and hazard ratios (HR) were estimated from Cox Proportional Hazards models. RESULTS Compared to never drinkers, wine drinkers experienced better overall survival (75% vs. 69% five-year survival rates, p-value for log-rank test = 0.030) and better disease free survival (70% vs. 67% five-year disease-free survival rates, p-value for log-rank test = 0.049). Analysis by NHL subtype shows that the favorable effect of wine consumption was mainly seen for patients diagnosed with diffuse large B-cell lymphoma (DLBCL) (wine drinkers for more than 25 years vs. never drinkers: HR = 0.36, 95% CI 0.14-0.94 for overall survival; HR = 0.38, 95% CI 0.16-0.94 for disease-free survival), and the adverse effect of liquor consumption was also observed among DLBCL patients (liquor drinkers vs. never drinkers: HR=2.49, 95% CI 1.26-4.93 for disease-free survival). CONCLUSIONS Our results suggest a moderate relationship between pre-diagnostic alcohol consumption and NHL survival, particularly for DLBCL. The results need to be replicated in larger studies. IMPLICATIONS FOR CANCER SURVIVORS Pre-diagnostic behaviors might impact the prognosis and survival of NHL patients.

Abstract
Drug metabolizing genes are involved in the detoxification of chemical carcinogens. Polymorphisms in drug-metabolizing genes affect the risk of some forms of cancer. We analyzed six polymorphisms to evaluate their association with risk for non-Hodgkin lymphoma (NHL), and to examine whether smoking modifies these associations in population-based study in Korea (713 cases and 1,700 controls). The GSTP1 rs1695 AG and the combined AG/GG genotypes were associated with decreased risk of NHL (odds ratio (OR)(AG) = 0.67, 95% confidence interval (CI) = 0.55-0.82; OR(AG/GG) = 0.66, 95% CI = 0.54-0.80) and DLBCL (OR(AG) = 0.63, 95% CI = 0.49-0.82; OR(AG/GG) = 0.64, 95% CI = 0.50-0.82). For T-cell lymphoma, only the combined AG/GG genotype was associated with decreased risk (OR(AG/GG) = 0.65, 95% CI = 0.44-0.96). The CYP1A1 rs1048943 AG genotype and the combined AG/GG genotypes were associated with increased risk of NHL (OR(AG) = 1.28, 95% CI = 1.07-1.54; OR(AG/GG) = 1.26, 95% CI = 1.06-1.51) and DLBCL (OR(AG) = 1.32, 95% CI = 1.04-1.66; OR(AG/GG) = 1.30, 95% CI = 1.03-1.63), but not T-cell lymphoma. Smoking does not modify the association between these polymorphisms and NHL risk. Our data provide evidence that the GSTP1 rs1695 and the CYP1A1 rs1048943 genotypes affect the risk of NHL in Korea.

Abstract
Given the lower incidence and differences in distribution of malignant lymphoma in Asian than western populations, the association of alcohol intake and smoking with malignant lymphoma risk in Asian populations merits investigation. Here, we conducted a sex- and age-matched case-control study of a Japanese population using two data sets, the first and second versions of the Hospital-based Epidemiological Research Program at Aichi Cancer Center Hospital (HERPACC-I and HERPACC-II, respectively), in 452 and 330 cases of histologically diagnosed malignant lymphoma and 2,260 and 1,650 noncancer controls, respectively. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated using a conditional logistic regression model that incorporated smoking exposure and alcohol intake. Compared with nondrinking, consumption of >or=50 g/d by frequent drinkers was associated with significantly decreased risk in both data sets [OR (95% CI), 0.70 (0.53-0.93) for HERPACC-I and 0.40 (0.23-0.68) for HERPACC-II]. Given similar findings among groups, we used pooled data sets in subsequent analyses. For any alcohol intake versus nondrinking, point estimates of OR were less than unity for all four malignant lymphoma subtypes. In contrast, pack-years of smoking were associated with increased malignant lymphoma risk: relative to the reference (0-4 pack-years), OR (95% CI) were 1.32 (1.02-1.71), 1.39 (1.07-1.80), and 1.48 (1.12-1.95) for 5 to 19, 20 to 39, and >or=40 pack-years, respectively. This association with smoking was less apparent for all subtypes, except Hodgkin's lymphoma. In conclusion, we found that alcohol had an inverse association with malignant lymphoma risk across all malignant lymphoma subtypes in our Japanese subjects. Smoking appeared to be positively associated with malignant lymphoma risk, but this finding may vary by subtype.

Abstract
Severe immune dysfunction is an established risk factor of lymphoma, but the role of moderate alterations of immunity is not clear and prospective investigations are needed. We examined several immune-related disorders and medications in relation to non-Hodgkin lymphoma (NHL) in the Multiethnic Cohort. Over 215,000 subjects of African American, Caucasian, Japanese American, Latino and Native Hawaiian ancestry aged 45-75 years completed a questionnaire, including information on medical history, in 1993-1996. After exclusions, we performed Cox regression among 193,050 cohort members including 939 incident NHL cases while adjusting for sex, age, ethnicity, education, body mass index and alcohol intake. Self-reported diabetes was not associated with NHL overall, but was positively associated with risk among Japanese Americans [hazard ratio (HR) = 1.55; 95% confidence interval (CI): 1.10-2.17]. Participants with a history of blood transfusion were at increased risk with HR = 1.39 (95% CI: 1.06-1.84) in men and HR = 1.22 (95% CI: 0.94-1.58) in women, especially for the diffuse large B-cell lymphoma subtype. History of asthma or other allergies was associated with elevated risk only among Latinos (HR = 1.46; 95% CI: 1.07-2.00) who also showed a significant relation between current use of antihistamines and NHL (HR = 1.80; 95% CI: 1.09-2.97). Use of nonsteroidal anti-inflammatory drugs was not associated with NHL. Our findings from this large prospective study support a moderate risk for NHL related to blood transfusions, current long-term antihistamine use and diabetes, but the associations were limited to certain ethnic groups and require further replications.

Abstract
We investigated variation in glutathione S-transferases (GSTs) and cytochrome P450s (CYPs), and smoking in a population-based case-control study of NHL including 1,115 women. Although risk of NHL was not altered by variant polymorphisms in GSTs or CYPs, it was significantly changed for DLBCL when considered in conjunction with smoking behavior, though only in nonsmokers. An increased risk of DLBCL in nonsmokers was associated with the variant G allele for GSTP1 (OR = 1.6, 95% CI 1.0-2.3) and CYP1A1 (OR = 2.4; 95% CI 1.0-5.7), but a decreased risk for the variant G allele for CYP1B1 (OR = 0.6, 95% CI 0.4-1.0). Our results confer support investigation of the gene-environment interaction in a larger study population of DLBCL.

Abstract
Several epidemiologic studies support the emerging paradigm that current alcohol consumers have decreased risk of most types of non-Hodgkin lymphoma. The observed lower risk among people who drank alcohol does not seem to vary with beverage type. The mechanisms accounting for alcohol-induced decrease in the incidence of lymphomas remain largely unknown. We demonstrate that low-dose chronic exposure to ethanol inhibits mammalian target of rapamycin (mTOR) C1 complex formation, resulting in decreased phosphorylation events involved in mTOR pathway signaling in a lymphoid-tissue specific manner. These changes in mTOR signaling lead to a decrease in eIF4E associated with the translation initiation complex and a repression of global cap-dependent synthesis in both lymphoma cell lines and normal donor lymphocytes. We show that chronic exposure of ethanol at physiologically relevant concentrations in a xenograft model results in a striking inhibition of lymphoma growth. Our data support a paradigm in which chronic ethanol exposure inhibits mTOR signaling in lymphocytes with a significant repression of cap-dependent translation, reducing the tumorigenic capacity of non-Hodgkin lymphoma in a human xenograft model. The ethanol-mediated repression of mTOR signaling coupled with decreased in vivo lymphoma growth underscore the critical role of mTOR signaling and translation in lymphoma.

Abstract
BACKGROUND With the exception of breast cancer, little is known about the effect of moderate intakes of alcohol, or of particular types of alcohol, on cancer risk in women. METHODS A total of 1,280,296 middle-aged women in the United Kingdom enrolled in the Million Women Study were routinely followed for incident cancer. Cox regression models were used to calculate adjusted relative risks and 95% confidence intervals (CIs) for 21 site-specific cancers according to amount and type of alcoholic beverage consumed. All statistical tests were two-sided. RESULTS A quarter of the cohort reported drinking no alcohol; 98% of drinkers consumed fewer than 21 drinks per week, with drinkers consuming an average of 10 g alcohol (1 drink) per day. During an average 7.2 years of follow-up per woman 68,775 invasive cancers occurred. Increasing alcohol consumption was associated with increased risks of cancers of the oral cavity and pharynx (increase per 10 g/d = 29%, 95% CI = 14% to 45%, Ptrend < .001), esophagus (22%, 95% CI = 8% to 38%, Ptrend = .002), larynx (44%, 95% CI = 10% to 88%, Ptrend = .008), rectum (10%, 95% CI = 2% to 18%, Ptrend = .02), liver (24%, 95% CI = 2% to 51%, Ptrend = .03), breast (12%, 95% CI = 9% to 14%, Ptrend < .001), and total cancer (6%, 95% CI = 4% to 7%, Ptrend < .001). The trends were similar in women who drank wine exclusively and other consumers of alcohol. For cancers of the upper aerodigestive tract, the alcohol-associated risk was confined to current smokers, with little or no effect of alcohol among never and past smokers (P(heterogeneity) < .001). Increasing levels of alcohol consumption were associated with a decreased risk of thyroid cancer (Ptrend = .005), non-Hodgkin lymphoma (Ptrend = .001), and renal cell carcinoma (Ptrend = .03). CONCLUSIONS Low to moderate alcohol consumption in women increases the risk of certain cancers. For every additional drink regularly consumed per day, the increase in incidence up to age 75 years per 1000 for women in developed countries is estimated to be about 11 for breast cancer, 1 for cancers of the oral cavity and pharynx, 1 for cancer of the rectum, and 0.7 each for cancers of the esophagus, larynx and liver, giving a total excess of about 15 cancers per 1000 women up to age 75.

Abstract
AIMS To identify occupations and industries associated with non-Hodgkin's lymphoma (NHL) in a large population-based, case-control study in the USA. METHODS Cases (n = 1189) of histologically confirmed malignant NHL ages 20-74 were prospectively identified in four geographic areas covered by the National Cancer Institute SEER Program. Controls (n = 982) were selected from the general population by random digit dialling (<65 years of age) and from residents listed in Medicare files (65-74 years of age). Odds ratios and 95% confidence intervals for occupations and industries were calculated by unconditional logistic regression analyses, adjusting for age, gender, ethnicity and study centre. Further analyses stratified for gender and histological subtype were also performed. RESULTS Risk of NHL was increased for a few occupations and industries. Several white collar occupations, with no obvious hazardous exposures, had elevated risks, including purchasing agents and buyers, religious workers, physical therapists and information clerks. Occupations with excesses that may have exposures of interest include launderers and ironers, service occupations, food/beverage preparation supervisors, hand packers and packagers, roofing and siding, leather and leather products, transportation by air, nursing and personal care facilities, and specialty outpatient clinics. Significantly decreased risks of NHL were found for a number of occupations and industries including post-secondary teachers and chemical and allied products. CONCLUSIONS The results of this study suggest that several occupations and industries may alter the risk of NHL. Our results support previously reported increased risks among farmers, printers, medical professionals, electronic workers and leather workers. These findings should be evaluated further in larger studies that have the power to focus on specific exposures and histological subtypes of NHL.

Abstract
Understanding patterns of etiologic commonality and heterogeneity for non-Hodgkin lymphomas may illuminate lymphomagenesis. We present the first systematic comparison of risks by lymphoma subtype for a broad range of putative risk factors in a population-based case-control study, including diffuse large B-cell (DLBCL; N = 416), follicular (N = 318), and marginal zone lymphomas (N = 106), and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL; N = 133). We required at least 2 of 3 analyses to support differences in risk: (1) polytomous logistic regression, (2) homogeneity tests, or (3) dichotomous logistic regression, analyzing all 7 possible pairwise comparisons among the subtypes, corresponding to various groupings by clinical behavior, genetic features, and differentiation. Late birth order and high body mass index (>/= 35) kg/m(2)) increased risk for DLBCL alone. Autoimmune conditions increased risk for marginal zone lymphoma alone. The tumor necrosis factor G-308A polymorphism (rs1800629) increased risks for both DLBCL and marginal zone lymphoma. Exposure to certain dietary heterocyclic amines from meat consumption increased risk for CLL/SLL alone. We observed no significant risk factors for follicular lymphoma alone. These data clearly support both etiologic commonality and heterogeneity for lymphoma subtypes, suggesting that immune dysfunction is of greater etiologic importance for DLBCL and marginal zone lymphoma than for CLL/SLL and follicular lymphoma.

Abstract
Hepatitis C virus (HCV) and hepatitis B virus (HBV) have been associated with hematopoietic malignancies, but data for many subtypes are limited. From the U.S. Surveillance, Epidemiology, and End Results-Medicare database, we selected 61,464 cases (> or = 67 years) with hematopoietic malignancies and 122,531 population-based controls, frequency-matched by gender, age, and year (1993--2002). Logistic regression was used to compare the prevalence of HCV, HBV, and alcoholic hepatitis in cases and controls, adjusted for matching factors, race, duration of Medicare coverage, and number of physician claims. HCV, HBV, and alcoholic hepatitis were reported in 195 (0.3%), 111 (0.2%), and 404 (0.7%) cases and 264 (0.2%), 242 (0.2%), and 798 (0.7%) controls, respectively. HCV was associated with increased risk of diffuse large B-cell lymphoma [odds ratio (OR) 1.52, 95% confidence interval (95% CI) 1.05-2.18], Burkitt lymphoma (OR 5.21, 95% CI 1.62-16.8), follicular lymphoma (OR 1.88, 95% CI 1.17-3.02), marginal zone lymphoma (OR 2.20, 95% CI 1.22-3.95), and acute myeloid leukemia (OR 1.54, 95% CI 1.00-2.37). In contrast, HBV was unrelated to any hematopoietic malignancies. Alcoholic hepatitis was associated with decreased risk of non-Hodgkin lymphoma overall, but increased risk of Burkitt lymphoma. In summary, HCV, but not other causes of hepatitis, was associated with the elevated risk of non-Hodgkin lymphoma and acute myeloid leukemia. HCV may induce lymphoproliferative malignancies through chronic immune stimulation.

Abstract
Although several epidemiologic studies have shown that gamma-glutamyltransferase (GGT) is associated with cardiovascular disease and all-cause mortality, its relationship with cancer incidence remains widely unexplored. In experimental models the ability of cellular GGT to modulate crucial redox-sensitive functions has been established, and it may thus play a role in tumor progression. In the present study, we investigated the association of GGT with overall and site-specific cancer incidence in a population-based cohort of 92,843 Austrian women with 349,674 serial GGT measurements, prospectively followed-up for a median of 13.5 years. The relationship between GGT and cancer incidence was analyzed using adjusted Cox regression models with age as underlying time metric with age as underlying time metric including GGT concentrations at baseline and incorporating repeated GGT measurements as a time-dependent variable. During follow-up, 4,884 incidence cancers were observed. Compared to normal low GGT (<17.99 U/L), cancer risk was elevated for all other GGT categories (p for trend < 0.0001), with adjusted hazard ratios (95% confidence intervals) of 1.06 (0.99-1.13) for GGT levels between 18.00 and 35.99 U/L (normal high), 1.12 (1.02-1.22) for GGT levels between 36.00 and 71.99 U/L (elevated) and 1.43 (1.28-1.61) for highly elevated GGT (>72.00 U/L). Very similar results were seen when GGT was analyzed as a time-dependent variable. In cancer-site specific models, elevated GGT statistically significantly increased the risk for malignant neoplasms of digestive organs, the respiratory system/intrathoracic organs, breast and female genital organs and lymphoid and haematopoietic cancers (all, p < 0.006). Our study is the first to demonstrate in a large population-based cohort that high GGT levels significantly increased cancer risk in women.

Abstract
Nutritional status is known to alter immune function, a suspected risk factor for non-Hodgkin lymphoma (NHL). To investigate whether long-term over, or under, nutrition is associated with NHL, self-reported anthropometric data on weight and height from over 10,000 cases of NHL and 16,000 controls were pooled across 18 case-control studies identified through the International Lymphoma Epidemiology Consortium. Study-specific odds ratios (OR) were estimated using logistic regression and combined using a random-effects model. Severe obesity, defined as BMI of 40 kg m(-2) or more, was not associated with NHL overall (pooled OR = 1.00, 95% confidence interval (CI) 0.70-1.41) or the majority of NHL subtypes. An excess was however observed for diffuse large B-cell lymphoma (pooled OR = 1.80, 95% CI 1.24-2.62), although not all study-specific ORs were raised. Among the overweight (BMI 25-29.9 kg m(-2)) and obese (BMI 30-39.9 kg m(-2)), associations were elevated in some studies and decreased in others, while no association was observed among the underweight (BMI < 18.5 kg m(-2)). There was little suggestion of increasing ORs for NHL or its subtypes with every 5 kg m(-2) rise in BMI above 18.5 kg m(-2). BMI components height and weight were also examined, and the tallest men, but not women, were at marginally increased risk (pooled OR = 1.19, 95% CI 1.06-1.34). In summary, whilst we conclude that there is no evidence to support the hypothesis that obesity is a determinant of all types of NHL combined, the association between severe obesity and diffuse large B-cell lymphoma may warrant further investigation.

Abstract
Tobacco smoking and alcohol consumption have not been clearly related to the risk of non-Hodgkin lymphoma (NHL), and the impact of these two factors on survival of NHL patients has received little attention. Cases were 268 subjects with incident histologically-confirmed NHL, admitted as inpatients to the Division of Medical Oncology, between 1983 and 2002. These individuals were enrolled as cases in case-control studies conducted at the same institution over the same period. For all patients clinical (histological subtype, major prognostic factors and treatment) and epidemiological data (smoking and drinking habits) were available. Survival analysis was performed using Kaplan-Meier methods. Hazard ratio (HR) was estimated by Cox proportional hazard model. Compared to never smokers, patients who smoked >or=20 cigarettes/day had higher risks of death (HR = 1.70, 95% confidence interval (CI): 1.06-2.73) and lower survivals at 5 years (60 and 46%, respectively). Likewise, patients who drunk >or=4 drinks/day showed 1.69-fold higher probability of death (95% CI: 1.04-2.76) in comparison to drinkers of <2 drinks/day (5-year survival: 47 and 67%, respectively). When combining exposure to alcohol and tobacco, no excess of death emerged in light drinkers (<4 drinks/day), irrespective of their smoking habits, but higher risks of death emerged among heavy drinkers. In the present study, heavy tobacco smoking, and particularly, heavy alcohol drinking were associated with poor survival in NHL patients. Our findings strongly encourage physicians to advice NHL patients to stop smoking and diminish alcohol consumption to obtain improvements in the course of NHL.

Abstract
The incidence of non-Hodgkin's lymphoma (NHL) has risen dramatically over recent decades and, despite some known risk factors, such as compromised immunity, the etiology of NHL and the reasons for most of this increase are unknown. Dietary components may be a common and critical source of immunologic antigens and promoters, which needs to be incorporated more in the etiologic research of NHL. To date, epidemiologic evidence suggests that obesity and fat intake, in particular saturated or animal fat, may increase the risk of NHL; whereas whole-grains, vegetables and moderate consumption of alcohol may be inversely associated with NHL risk. Much of the current evidence is obtained from case-control studies, which are subject to dietary recall bias; therefore, this area of research requires further study within prospective cohorts with detailed dietary information and with a large number of cases to examine disease sub-type heterogeneity.

Abstract
Dietary deficiency of folate and other micronutrients involved in the one-carbon metabolism (i.e., vitamins B2, B6, B12, and methionine) have been related to several diseases, including cancers, but results on non-Hodgkin lymphoma (NHL) are controversial. A hospital-based case-control study was conducted in Italy, in 1999-2002. Cases were 190 incident, histologically confirmed NHL aged 18-84 years. Controls were 484 subjects admitted to hospitals for acute, non-neoplastic diseases supposed to be unrelated to alcohol consumption or to diet modification. Dietary habits, including alcohol drinking, were assessed by a validated food-frequency questionnaire. Nutrient intakes were computed using the Italian food composition database. Odds ratios (ORs) and corresponding 95% confidence intervals for tertiles of nutrients' intake were computed using the energy-adjusted residual models. No significant association emerged between NHL risk and intakes of folate (OR=0.9), vitamin B2 (OR=0.9), vitamin B6 (OR=0.8), and methionine (OR=0.7). However, a significant inverse association was observed for all the nutrients examined among abstainers and former drinkers, whereas no relations between one-carbon nutrients and NHL risk emerged among current alcohol drinkers. Our findings support the possibility of an antagonist effect of alcohol on the one-carbon metabolism in NHL etiology. However, the lack of an overall effect for one-carbon nutrients and the small sample size suggested caution in interpreting our results.

Abstract
Two common single nucleotide polymorphisms in immunoregulatory genes (TNF G308A, rs1800629 and IL10 T3575A, rs1800890) have been recently reported as risk factors for non-Hodgkin lymphoma (NHL) in a large pooled analysis. We systematically investigated the effects of other established NHL risk factors in relation to the tumor necrosis factor (TNF) G308A or interleukin 10 (IL10) T3575A genotypes. We calculated odds ratios (OR) and 95% confidence intervals (95% CI) from 1,172 cases and 982 population-based controls in a U.S. multicenter study. We investigated NHL overall and two common subtypes [diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma]. NHL risks were increased among those with both an autoimmune condition and the TNF G308A GA/AA (OR(NHL), 2.1; 95% CI, 1.0-4.2) or the IL10 T3575A TA/AA genotype (OR(NHL), 1.6; 95% CI, 0.9-2.6) compared with individuals without an autoimmune condition and with the common TNF G308A GG or IL10 T3575A TT genotype, respectively; results were similar for DLBCL and follicular lymphoma. We found that elevated DLBCL risk associated with last-born status was more pronounced among those with TNF G308A GA/AA (OR(DLBCL), 2.7; 95% CI, 1.1-6.4) or IL10 T3575A TA/AA (OR(DLBCL), 2.9; 95% CI, 1.6-5.2). Similarly, elevated DLBCL risk associated with obesity (body mass index, > or = 35 versus <25 kg/m(2)) was observed only among those with TNF G308A GA/AA (OR(DLBCL), 2.5; 95% CI, 1.1-5.7) or IL10 T3575A TA/AA genotypes (OR(DLBCL), 2.0; 95% CI, 1.1-3.5). These exploratory results require replication but provide evidence that autoimmune conditions, late birth order, and obesity act partly through a common inflammatory pathway, posing a greater risk to individuals with variant TNF and IL10 genotypes than those with wild-type alleles.

Abstract
A multi-centre hospital-based case-control study was conducted in three regions of France between 2000 and 2003 in order to establish the risk factors of lymphoid neoplasms. We report here results concerning alcohol and tobacco consumption. A total of 298 cases and 276 controls, case-matched by inclusion centre, age and sex were included. Cases were classified according to the World Health Organization classification and validated by an expert panel of eight pathologists. Overall alcohol intake did not incur any risk increase for non-Hodgkin's lymphoma. Wine consumption marginally increased the risk of follicular lymphoma [odds ratio=2.19 (0.83-5.80)], with a higher risk for drinkers who started before the age of 20 years [odds ratio=4.04 (1.19-13.76)] and for drinkers who consumed more than 19 g of alcohol per day [odds ratio=4.37 (1.04-18.45)]. Beer and spirit consumption was not linked to non-Hodgkin's lymphoma risk. Tobacco consumption did not show a risk increase. The risk increase of follicular lymphoma due to wine consumption was new. We discuss this risk based on the French context, France being the European country with the highest alcohol consumption, particularly of wine.

Abstract
The non-Hodgkin lymphomas (NHL) are a heterogeneous group of B-cell and T-cell neoplasms that arise primarily in the lymph nodes. NHL incidence rates in the US doubled between about 1970 and 1990, and stabilized during the 1990s. NHL accounts for approximately 3.4% of cancer deaths in the US. Although some of the observed patterns in NHL have been related to HIV/AIDS, these conditions cannot fully explain the magnitude of the changes; neither do changes in classification systems nor improved diagnostic capabilities. Studies of occupational and environmental exposures (e.g., pesticides, solvents) have produced no consistent pattern of significant positive associations. Inverse associations with ultraviolet radiation exposure and alcohol and fish intake, and positive associations with meat and saturated fat intake have been reported in several studies; additional studies are needed to confirm or refute these associations. Family history of NHL or other hematolympho-proliferative cancers and personal history of several autoimmune disorders are associated with increased risk of NHL, but are not likely to account for a large proportion of cases. HIV and other infectious agents, such as human herpesvirus 8 and Epstein-Barr, appear to be associated with differing types of NHL, such as some B-cell lymphomas. Future epidemiologic studies should evaluate associations by NHL type, enhance exposure information collected, and elucidate factors that may identify susceptible (or resistant) subpopulations because of genetic, immunologic or other characteristics. The extent to which the etiology of NHL types may differ is important to resolve in ongoing and future studies.

Abstract
INTRODUCTION Lymphomas are a heterogeneous group of malignant diseases of cells of the immune system. The best-established risk factors are related to dys-regulation of immune function, and evidence suggests that factors such as dietary or lifestyle habits may be involved in the etiology. MATERIAL AND METHODS In the European Prospective Investigation into Cancer and Nutrition (EPIC), 849 lymphoma cases were identified in a median follow-up period of 6.4 years. Fruit and vegetable consumption was estimated from validated dietary questionnaires. Cox proportional hazard models were used to examine the association between fruit and vegetable intake with the risk of lymphomas overall and subentities. RESULTS There was no overall association between total fruit and vegetable consumption and risk of lymphoma [hazard ratio (HR)=0.95, 95% confidence interval (CI) 0.78-1.15 comparing highest with lowest quartile]. However, the risk of diffuse large B-cell lymphomas (DLBCL) tended to be lower in participants with a high intake of total vegetables (HR=0.49, 95% CI 0.23-1.02). CONCLUSION In this large prospective study, an inverse associations between fruit and vegetable consumption and risk of lymphomas overall could not be confirmed. Associations with lymphoma subentities such as DLBCL warrant further investigation.

Abstract
Recent evidence suggests that there is etiologic heterogeneity among the various subtypes of lymphoid neoplasms. However, epidemiologic analyses by disease subtype have proven challenging due to the numerous clinical and pathologic schemes used to classify lymphomas and lymphoid leukemias over the last several decades. On behalf of the International Lymphoma Epidemiology Consortium (InterLymph) Pathology Working Group, we present a proposed nested classification of lymphoid neoplasms to facilitate the analysis of lymphoid neoplasm subtypes in epidemiologic research. The proposed classification is based on the World Health Organization classification of lymphoid neoplasms and the International Classification of Diseases-Oncology, Third Edition (ICD-O-3). We also provide a translation into the proposed classification from previous classifications, including the Working Formulation, Revised European-American Lymphoma (REAL) classification, and ICD-O-2. We recommend that epidemiologic studies include analyses by lymphoma subtype to the most detailed extent allowable by sample size. The standardization of groupings for epidemiologic research of lymphoma subtypes is essential for comparing subtype-specific reports in the literature, harmonizing cases within a single study diagnosed using different systems, as well as combining data from multiple studies for the purpose of pooled analysis or meta-analysis, and will probably prove to be critical for elucidating etiologies of the various lymphoid neoplasms.

Abstract
A population-based case-control study of 649 leukemia cases and 1771 controls carried out in 11 Italian areas, offered the opportunity to evaluate the relationship between alcohol consumption and leukemia risk. For all leukemias, acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), and chronic lymphocytic leukemia (CLL), we found a non-significantly inverse association for moderate levels of total alcohol and wine intake, but increased risks at high levels, with, in most cases, significant trend effects (odd ratios (OR) for all leukemias in the lowest quartile of total alcohol consumption [0.1-9.0 g/day of ethanol] versus never-drinker = 0.73; 95% confidence intervals (95% CI) = 0.51-1.03; OR in the highest quartile [> 31.7 g/day] = 1.15; 95% CI = 0.82-1.63; p of the linear trend test = 0.007). For chronic myeloid leukemia (CML), we found a non-significantly positive association for all levels of total alcohol and wine intake, and a significant positive linear trend effect (p = 0.03) for wine intake (OR for 0.1-9.0 g/day of ethanol intake from wine = 1.34; 95% CI = 0.61-2.94; OR in the highest quartile of wine intake [> 27.7 g/day] = 2.13; 95% CI = 1.01-4.50). No consistent dose-response was detected analysing duration of alcohol consumption for any leukemia subtypes. In conclusion, even though our study did not show a clear association between alcohol intake and leukemia risk, some of the patterns of the risk estimates (a possible J-shaped dose-response curve between alcohol intake and ALL, AML, and CLL risks, and the positive association between alcohol and CML), may be suggestive.

Abstract
The role of alcoholic beverages in bladder carcinogenesis is still unclear, with conflicting evidence from different studies. We investigated the relationship between alcohol consumption and bladder cancer, and the potential interaction between alcohol consumption and other exposures. In a population-based case-control study conducted in Los Angeles County, 1,586 pairs of cases and their matched neighborhood controls were interviewed. Data were analyzed to determine whether bladder cancer risk differs by alcohol consumption, and whether different alcoholic beverages have different effects. The risk of bladder cancer decreased with increasing frequency (p for trend = 0.003) and duration of alcohol consumption (p for trend = 0.017). Subjects who drank more than 4 drinks per day had a 32% lower (odds ratio, 0.68; 95% confidence interval, 0.52-0.90) risk of bladder cancer than those who never drank any alcoholic beverage. Beer (p for trend = 0.002) and wine (p for trend = 0.054) consumption were associated with reduced risk of bladder cancer, while hard liquor was not. The reduction in risk was mostly seen among shorter-term smokers who urinated frequently. Alcohol consumption was strongly associated with a reduced risk of bladder cancer. The effect was modified by the type of alcoholic beverage, cigarette smoking and frequency of urination.

Abstract
In 2004-2007 4 independent case-control studies reported evidence that sun exposure might protect against NHL; a fifth, in women only, found increased risks of NHL associated with a range of sun exposure measurements. These 5 studies are the first to examine the association between personal sun exposure and NHL. We report here on the relationship between sun exposure and NHL in a pooled analysis of 10 studies participating in the International Lymphoma Epidemiology Consortium (InterLymph), including the 5 published studies. Ten case-control studies covering 8,243 cases and 9,697 controls in the USA, Europe and Australia contributed original data for participants of European origin to the pooled analysis. Four kinds of measures of self-reported personal sun exposure were assessed at interview. A two-stage estimation method was used in which study-specific odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for potential confounders including smoking and alcohol use, were obtained from unconditional logistic regression models and combined in random-effects models to obtain the pooled estimates. Risk of NHL fell significantly with the composite measure of increasing recreational sun exposure, pooled OR = 0.76 (95% CI 0.63-0.91) for the highest exposure category (p for trend 0.01). A downtrend in risk with increasing total sun exposure was not statistically significant. The protective effect of recreational sun exposure was statistically significant at 18-40 years of age and in the 10 years before diagnosis, and for B cell, but not T cell, lymphomas. Increased recreational sun exposure may protect against NHL.

Abstract
BACKGROUND A number of studies have shown possible associations between occupational exposures, particularly solvents, and lymphomas. The present investigation aimed to evaluate the association between exposure to solvents and lymphomas (Hodgkin and non-Hodgkin) in a large population-based, multicenter, case-control study in Italy. METHODS All newly diagnosed cases of malignant lymphoma in men and women age 20 to 74 years in 1991-1993 were identified in 8 areas in Italy. The control group was formed by a random sample of the general population in the areas under study stratified by sex and 5-year age groups. We interviewed 1428 non-Hodgkin lymphoma cases, 304 Hodgkin disease cases, and 1530 controls. Experts examined the questionnaire data and assessed a level of probability and intensity of exposure to a range of chemicals. RESULTS Those in the medium/high level of exposure had an increased risk of non-Hodgkin lymphoma with exposure to toluene (odds ratio = 1.8; 95% confidence interval = 1.1-2.8), xylene 1.7 (1.0-2.6), and benzene 1.6 (1.0-2.4). Subjects exposed to all 3 aromatic hydrocarbons (benzene, toluene, and xylene; medium/high intensity compared with none) had an odds ratio of 2.1 (1.1-4.3). We observed an increased risk for Hodgkin disease for those exposed to technical solvents (2.7; 1.2-6.5) and aliphatic solvents (2.7; 1.2-5.7). CONCLUSION This study suggests that aromatic and chlorinated hydrocarbons are a risk factor for non-Hodgkin lymphomas, and provides preliminary evidence for an association between solvents and Hodgkin disease.

The etiology of non-Hodgkin lymphoma, as well as its global dramatic rise in incidence during the past decades, remains largely unexplained. However, there is increasing awareness that this group of malignancies may entail not only clinical, morphological and molecular heterogeneity, but also considerable variations in terms of etiologic factors. In this review, epidemiologic patterns are summarized as well as current evidence of associations between various known or suspected risk factors for non-Hodgkin lymphoma overall or for any of its subtypes. Central pathogenetic mechanisms include immunosuppression, especially in relation to T-cell function and loss of control of latent EBV infection, and chronic antigen stimulation. Some degree of familiar aggregation also implies a role for genetic susceptibility. A number of recent investigations of non-Hodgkin lymphoma etiology will hopefully lead to a better understanding of the causes of these malignancies.

Abstract
BACKGROUND Few studies have analysed the association between alcohol intake and Hodgkin's lymphoma (HL) or multiple myeloma (MM) risks. MATERIALS AND METHODS A multicentre population-based case-control study of 363 HL, 270 MM cases, and 1771 controls offered the opportunity to evaluate the relationship between alcohol and HL/MM risks. Unconditional logistic regression was carried out to estimate odds ratios (ORs) and 95% confidence intervals (CIs), associated with alcohol intake (servings per week, grams per day of ethanol intake) or duration of exposure (year). RESULTS For HL, considering nonsmokers only, ever drinkers had a significantly decreased risk than never drinkers (OR=0.46). Significantly lower risks in all levels of total alcohol intake were also detected, considering servings per week (OR for one to four servings per week=0.51, 95% CI 0.32-0.82; OR for five to nine servings per week=0.39, 95% CI 0.21-0.73; OR for 10-19 servings per week=0.26, 95% CI 0.12-0.54; OR for >or=20 servings per week=0.34, 95% CI 0.15-0.79) and grams per day of ethanol intake (OR for 0.1-9.0 g/day=0.45, 95% CI 0.27-0.74; OR for 9.1-17.9 g/day=0.52, 95% CI 0.30-0.90; OR for 18.0-31.7 g/day=0.27, 95% CI 0.13-0.57; OR for >31.7 g/day=0.35, 95% CI 0.15-0.79). In the analysis for ever-smoking HL cases and controls, ever drinkers had the same risk as never drinkers. For MM, ever drinkers had a non-significantly decreased risk than non-drinkers (OR=0.74), and ORs in almost all consumption levels were not significant (OR for 0.1-9.0 g/day=0.93; OR for 9.1-17.9 g/day=0.82; OR for 18.0-31.7 g/day=0.47; 95% CI 0.28-0.81; OR for >31.7 g/day=0.68). For HL and MM, the beverage type did not affect the risk significantly, and no consistent dose-response relationships were found, considering intensity or duration of alcohol consumption. CONCLUSIONS Our study indicates a protective effect of alcohol consumption for nonsmoking HL cases.

Abstract
OBJECTIVE Because of conflicting findings about the relationship between ultraviolet (UV) radiation and the risk of non-Hodgkin lymphoma (NHL), we evaluated the risk of several indicators related to UV, including two not previously studied: dietary vitamin D, and ambient UV levels by residential location. METHODS As part of a case-control study conducted in four Surveillance, Epidemiology, and End Results (SEER) registries, we collected UV information from a self-administered questionnaire and computer-assisted personal interview with 551 NHL cases and 462 controls. We estimated the relative risk (RR) and 95% confidence intervals (CI) from unconditional logistic regression models. RESULTS Eye color, a marker of host susceptibility to UV, showed a decreasing risk gradient for lightest eyes (0.47) compared to darkest. Relative risks were in the range of 0.73-0.78 for participants reporting more hours in the mid-day summer sun. Use of sunlamps or tanning booths was associated with decreased risk (RR = 0.88), as was estimated overall ambient UV (RR = 0.76 per 50 RB-units) overall. Vitamin D intake from diet and supplements was not related to risk. Results were thus consistent for the various indicators, although some estimated risks were not statistically significant. Effects were generally similar for diffuse large B-cell (DLBCL) and follicular lymphomas. CONCLUSION These data suggest a slight protective effect of sunlight against NHL, and they agree with geographic patterns of NHL incidence observed in the US.

Abstract
METHODS Meta-analysis and review of 14 occupational cohort and four case-control studies of workers exposed to trichloroethylene (TCE) to investigate the relation between TCE exposure and the risk of non-Hodgkin's lymphoma (NHL). Studies were selected and categorised based on a priori criteria, and results from random effects meta-analyses are presented. RESULTS The summary relative risk estimates (SRRE) for the group of cohort studies that had more detailed information on TCE exposure was 1.29 (95% CI 1.00 to 1.66) for the total cohort and 1.59 (95% CI 1.21 to 2.08) for the seven studies that identified a specific TCE exposed sub-cohort. SRREs for three studies with cumulative exposure information were 1.8 (95% CI 0.62 to 5.26) for the lowest exposure category and 1.41 (95% CI 0.61 to 3.23) for the highest category. Comparison of SRREs by levels of TCE exposure did not indicate exposure-response trends. The remaining cohort studies that identified TCE exposure but lacked detailed exposure information had an SRRE of 0.843 (95% CI 0.72 to 0.98). Case-control studies had an SRRE of 1.39 (95% CI 0.62 to 3.10). Statistically significant findings for the Group 1 studies were driven by the results from the subgroup of multiple industry cohort studies (conducted in Europe) (SRRE = 1.86; 95% CI 1.27 to 2.71). The SRRE for single industry cohort studies was not significantly elevated (SRRE = 1.25; 95% CI 0.87 to 1.79). CONCLUSIONS Interpretation of overall findings is hampered by variability in results across the Group 1 studies, limited exposure assessments, lack of evidence of exposure response trends, lack of supportive information from toxicological and mechanistic data, and absence of consistent findings in epidemiologic studies of exposure and NHL. Although a modest positive association was found in the TCE sub-cohort analysis, a finding attributable to studies that included workers from multiple industries, there is insufficient evidence to suggest a causal link between TCE exposure and NHL.

Abstract
We estimated the number of cancer cases and deaths attributable to alcohol drinking in 2002 by sex and WHO subregion, based on relative risks of cancers of the oral cavity, pharynx, esophagus, liver, colon, rectum, larynx and female breast obtained from recent meta- and pooled analyses and data on prevalence of drinkers obtained from the WHO Global Burden of Disease project. A total of 389,100 cases of cancer are attributable to alcohol drinking worldwide, representing 3.6% of all cancers (5.2% in men, 1.7% in women). The corresponding figure for mortality is 232,900 deaths (3.5% of all cancer deaths). This proportion is particularly high among men in Central and Eastern Europe. Among women, breast cancer comprises 60% of alcohol-attributable cancers. Although our estimates are based on simplified assumptions, the burden of alcohol-associated cancer appears to be substantial and needs to be considered when making public health recommendations on alcohol drinking.
