Flavonoids and risk of squamous cell esophageal cancer.

The relation between 5 classes of flavonoids (flavanones, flavan-3-ols, flavonols, flavones and anthocyanidines) and esophageal cancer was investigated using data from a case-control study conducted between 1992 and 1997 in 3 areas of northern Italy. The study included 304 cases (275 men, 29 women) with a first diagnosis of squamous-cell carcinoma of the esophagus and 743 controls (593 men, 150 women) with no history of cancer, admitted for acute illnesses, unrelated to tobacco and alcohol consumption, to major hospitals of the areas under surveillance. Dietary habits were investigated using a validated food frequency questionnaire. Odds ratios (ORs) and 95% confidence intervals (CI) were computed after allowance for age, sex, study centre, years of education, alcohol drinking, tobacco smoking, body mass index and energy intake. An inverse association emerged between flavanone intake and esophageal cancer risk (OR=0.38 for the highest vs. the lowest quintile, 95% CI=0.23-0.66). The inverse relation between flavanones and esophageal cancer tended to be stronger in those who drank >or=6 drinks/day. In conclusion, this study suggests that flavanone intake is inversely associated with esophageal cancer risk and may account, with vitamin C, for the protective effect of fruit, especially citrus fruit, on esophageal cancer.

Coffee and tea consumption and risk of hepatocellular carcinoma in Italy.

The role of coffee in the aetiology of hepatocellular carcinoma has raised great interest. In Italy, coffee consumption is high, thus allowing the investigation of the topic over a broad range of consumption. A hospital-based case-control study was conducted in Italy in 1999-2002, including 185 incidents, histologically confirmed cases of hepatocellular carcinoma aged 43-84 years. Controls were 412 subjects admitted to the same hospitals' networks for acute, non-neoplastic diseases unrelated to diet. Coffee and tea consumption were assessed using a validated food-frequency questionnaire. Odds ratios (ORs) and corresponding the 95% confidence intervals (CI) were computed using unconditional multiple logistic regression, adjusting for hepatitis viruses seropositivity, alcohol intake, smoking habits and other potential confounding factors. Compared to people who drunk <14 cups/week of coffee, the risk of hepatocellular carcinoma decreased for increasing levels of consumption (OR=0.4, 95% CI: 0.2-1.1 for >or=28 cups/week, p for trend = 0.02). In the present study, inverse relations were observed across strata of hepatitis C and, B virus infections and alcohol drinking. No significant association emerged with consumption of decaffeinated coffee (OR=0.7, 95% CI=0.2-2.5) or tea (OR=1.4, 95% CI=0.8-2.7). The present study supports the hypothesis of a favourable effect of coffee, though not decaffeinated coffee and tea, on the risk on hepatocellular carcinoma.

Micronutrients and the risk of renal cell cancer: a case-control study from Italy.

The role of various micronutrients on the risk of renal cell cancer (RCC) was examined in a multicentric case-control study from Italy, in which information on dietary habits were collected using a validated food-frequency questionnaire. Cases were 767 patients (494 men and 273 women) with incident, histologically confirmed RCC; controls were 1,534 subjects (988 men and 546 women) admitted to the same hospitals as cases for a wide spectrum of acute, nonneoplastic conditions. After allowing for energy and other major covariates, a significant inverse association was found for vitamin E (odds ratio, OR, for the highest quintile of intake versus the lowest one 0.56, 95% confidence interval, CI 0.41-0.75), and vitamin C (OR = 0.72, 95% CI = 0.54-0.96), although the trend in risk for vitamin C was of borderline significance. No significant trend of decreasing risk was found for other micronutrients analyzed, although for most of them the risk estimates were below unity for intakes above the lowest. The ORs for the upper quintile of intake when compared with the lowest one were 0.80 (95% confidence interval, CI = 0.59-1.08) for retinol, 0.82 (95% CI = 0.61-1.10) for alpha-carotene, 0.90 (95% CI = 0.68-1.20) for beta-carotene, 0.94 (95% CI = 0.73-1.21) for beta-criptoxanthin, 0.85 (95% CI = 0.63-1.14) for lutein/zeaxanthin, 0.76 (95% CI = 0.57-1.01) for vitamin D, 0.75 (95% CI = 0.55-1.01) for thiamine, 0.88 (95% CI = 0.66-1.19) for riboflavin, 0.85 for vitamin B6 (95% CI = 0.64-1.13), 0.85 (95% CI = 0.64-1.12) for folate and 0.80 (95% CI = 0.60-1.07) for niacin. No meaningful associations emerged for lycopene (OR = 1.11). The present findings support a possible beneficial effect of vitamin E and C on RCC.

Family history of hematopoietic malignancies and risk of non-Hodgkin lymphoma (NHL): a pooled analysis of 10 211 cases and 11 905 controls from the International Lymphoma Epidemiology Consortium (InterLymph).

A role for genetic susceptibility in non-Hodgkin lymphoma (NHL) is supported by the accumulating evidence of common genetic variations altering NHL risk. However, the pattern of NHL heritability remains poorly understood. We conducted a pooled analysis of 10 211 NHL cases and 11 905 controls from the International Lymphoma Epidemiology Consortium (InterLymph) to evaluate NHL risk among those with hematopoietic malignancies in first-degree relatives. Odds ratios (ORs) and 95% confidence intervals (CIs) of NHL and its subtypes were estimated from unconditional logistic regression models with adjustment for confounders. NHL risk was elevated for individuals who reported first-degree relatives with NHL (OR = 1.5; 95% CI = 1.2-1.9), Hodgkin lymphoma (OR = 1.6; 95% CI = 1.1-2.3), and leukemia (OR = 1.4; 95% CI = 1.2-2.7). Risk was highest among individuals who reported a brother with NHL (OR = 2.8; 95% CI = 1.6-4.8) and was consistent for all NHL subtypes evaluated. If a first-degree relative had Hodgkin lymphoma, NHL risk was highest if the relative was a parent (OR = 1.7; 95% CI = 1.0-2.9). If a first-degree relative had leukemia, NHL risk was highest among women who reported a sister with leukemia (OR = 3.0; 95% CI = 1.6-5.6). The pattern of NHL heritability appeared to be uniform across NHL subtypes, but risk patterns differed by specific hematopoietic malignancies and the sex of the relative, revealing critical clues to disease etiology.

Food groups and risk of hepatocellular carcinoma: A multicenter case-control study in Italy.

The role of diet, except for alcohol drinking and aflatoxin contamination, in the etiology of hepatocellular carcinoma (HCC) is unclear. A hospital-based case-control study was conducted in Italy in 1999-2002, including 185 incident, histologically-confirmed cases of HCC. Controls were 412 subjects admitted to hospitals for acute, nonneoplastic diseases unrelated to diet. Dietary habits were assessed using a validated food-frequency questionnaire. Odds ratios (ORs) and the corresponding 95% confidence intervals (CI) were computed using unconditional multiple logistic regression, adjusting for hepatitis B (HBV) and hepatitis C (HCV) virus infection and alcohol drinking. Energy adjustment was carried out by means of the residual model. A significant inverse relation was found between intakes of milk and yoghurt (OR = 0.28; 95% CI: 0.13-0.61), white meats (OR = 0.44; 95% CI: 0.20-0.95), eggs (OR = 0.31; 95% CI: 0.14-0.69), and fruits (OR = 0.48; 95% CI: 0.22-1.05) and HCC risk. The favourable effect of high intakes of milk and yoghurt, white meats, eggs and fruits was consistent across strata of HBV and HCV infections. The present study supports the hypothesis of a role of diet in HCC aetiology. Dietary modifications may be indicated in subjects at high-risk for HCC.

Food groups and risk of non-Hodgkin lymphoma: a multicenter, case-control study in Italy.

Incidence of non-Hodgkin lymphoma (NHL) has been rising worldwide, but the reasons are undefined. Dietary habits may play a role in the etiology of NHL by influencing the metabolic pathways of several cells of the immune system. This case-control study investigated the relation between food consumption and NHL risk. Between 1999 and 2002, we conducted a hospital-based case-control study on NHL in 2 areas of Italy. Cases were 190 patients (median age 58 years) with incident NHL admitted to specialized and general hospitals. Controls were 484 patients (median age 63 years) with acute non-neoplastic conditions admitted to the same hospitals network of cases. A validated food-frequency questionnaire was used to assess habitual diet 2 years before interview. Unconditional multiple logistic regression was used to estimate the odds ratios (OR) and the corresponding 95% confidence intervals (CI), with allowance for energy intake, according to the residual model. Consumption of highest versus lowest quartile of pasta/rice (OR = 1.87, 95% CI: 1.04-3.36) and cheese (OR = 1.66, 95% CI: 0.98-2.83) were associated with a significantly increased NHL risk. Inverse association was found for vegetables (OR = 0.49, 95% CI: 0.28-0.87), fruits (OR = 0.51, 95% CI: 0.30-0.85), and egg consumption (OR = 0.59, 95% CI: 0.36-0.97). The association of pasta/rice was also supported by an increased risk of high glycemic load levels (OR = 1.86, 95% CI: 1.04-3.32). In conclusion, our results suggested that diet could affect NHL risk.

Lifetime occupational and recreational physical activity and risk of benign prostatic hyperplasia.

To investigate the relation between occupational and recreational physical activity (PA) in different periods of life and the risk of benign prostatic hyperplasia (BPH), we conducted a hospital-based, case-control study in Italy. The study included 1,369 histologically confirmed BPH and 1,451 controls, admitted to the same hospitals for acute, nonneoplastic diseases. Odds ratios (ORs) and 95% confidence intervals (CIs) of BPH, according to lifetime PA, were obtained by unconditional multiple logistic regression models, including terms for age, study center and education. Compared to the lowest level of occupational PA, the multivariate ORs for BPH for the heavy/strenuous level were 0.6 (95% CI, 0.4-0.8) at age 15-19, 0.6 (95% CI, 0.4-0.8) at age 30-39 and 0.7 (95% CI, 0.5-0.9) at age 50-59. Moreover, compared to <2 hr/week of recreational PA, the ORs for BPH for the highest level (>or=5 hr/week) were 0.5 (95% CI, 0.4-0.7) at age 15-19, 0.6 (95% CI, 0.5-0.8) at age 30-39, and 0.7 (95% CI, 0.5-0.8) at age 50-59. All inverse trends in risk were significant, and no heterogeneity was found by reason of BPH-diagnosis, age at diagnosis, and body mass index (BMI). The inverse association between PA and BPH risk may be due to favorable hormonal correlates of PA, but residual confounding by socioeconomic covariates cannot be excluded. A moderate PA at any ages may help reducing a sizeable number of BPH.

Do childhood diseases affect NHL and HL risk? A case-control study from northern and southern Italy.

To investigate the association between non-Hodgkin lymphoma (NHL), Hodgkin lymphoma (HL), and exposure to childhood diseases, we analyzed an Italian case-control study that included 225 histologically-confirmed incident cases of NHL, 62 HL cases, and 504 controls. After adjusting for confounding factors, all examined childhood diseases were negatively associated with HL. Measles was negatively associated with NHL, particularly follicular B-cell NHL. Our findings provide additional support to the hypothesis that infections by most common childhood pathogens may protect against HL or, at least, be correlated with some other early exposure, which may lower the risk of HL in adulthood. In addition, our study shows that measles may provide a protective effect against NHL.

A scoring system based on the expression of six surface molecules allows the identification of three prognostic risk groups in B-cell chronic lymphocytic leukemia.

We have previously identified 12 surface antigens whose differential expression represented the signature of B-cell chronic lymphocytic leukemia (B-CLL) subsets with different prognosis. In the present study, expression data for these antigens, as determined in 137 B-CLL cases, all with survivals, were utilized to devise a comprehensive immunophenotypic scoring system of prognostic relevance for B-CLL patients. In particular, univariate z score was employed to identify the markers with greater prognostic impact, while maximally selected log-rank statistics were chosen to define the optimal cut-off points capable to split patients into two groups with different survivals. A weighted immunophenotypic scoring system was developed by integrating results from these analyses. Six antigens were selected: three positive prognosticators (CD62L, CD54, CD49c) and three negative prognosticators (CD49d, CD38, CD79b), with cut-off values ranging from 30% to 50% of positive cells. By weighing the expression of each marker according to its statistical power, a complete scoring system, with point values comprised between 0 (complete absence of phenotypic conditions associated with good prognosis) and 9 (all the phenotypic conditions associated with good prognosis fulfilled), allowed to split the whole set of B-CLL patients, into three distinctive prognostic groups (P = 4.78 x 10(-11)) with high- (score 0-3), intermediate- (score 4-6), and low- (score 7-9) risk of death. The three risk groups showed different distribution of cases as for Rai's stages, IgVH mutations, and ZAP-70 expression. The proposed immunophenotypic scoring system may be an additional useful tool in routine diagnostic/prognostic procedures for B-CLL.

Food groups and risk of benign prostatic hyperplasia.

OBJECTIVES: To evaluate the role of a wide range of foods on the risk of benign prostatic hyperplasia (BPH), we conducted a case-control study in Italy between 1991 and 2002. Although BPH is an extremely common condition, particularly among older men, its risk factors, including dietary ones, remain largely undefined. METHODS: Included in the study were 1369 patients younger than 75 years old surgically treated for BPH and 1451 controls younger than 75 years of age who had been admitted to the same hospitals as cases for a wide spectrum of acute, non-neoplastic conditions. A validated and reproducible food frequency questionnaire, including 78 foods and beverages, plus a separate section on alcoholic beverages, was used to assess patients' dietary habits 2 years before diagnosis or hospital admission. Multivariate odds ratios (OR) were obtained after allowance for energy intake and other major potential confounding factors. RESULTS: A significant trend of increasing risk with more frequent consumption was found for cereals (OR 1.55 for the greatest versus lowest quintile), bread (OR 1.69), eggs (OR 1.43), and poultry (OR 1.39). Inverse associations were observed for soups (OR 0.74), pulses (OR 0.74), cooked vegetables (OR 0.66), and citrus fruit (OR 0.82). No association was observed for milk and yogurt products, coffee and tea, pasta and rice, fish, cheese, row vegetables, potatoes, fruit, or desserts. CONCLUSIONS: The results of this study suggest a role for dietary habits on the risk of BPH. In particular, a diet rich in cereals and some types of meat and poor in vegetables and pulses may have an unfavorable effect in this Italian population.

Macronutrients, fatty acids, cholesterol, and risk of benign prostatic hyperplasia.

OBJECTIVES: To better understand the role of specific macronutrients on the risk of benign prostatic hyperplasia (BPH), we used data from an Italian case-control study. Although BPH is extremely common among the elderly, its etiology-and, particularly, the role of diet and specific macronutrients-is still unclear. METHODS: A case-control study of 1369 patients with BPH and 1451 controls, admitted to the same hospitals for a wide spectrum of acute, non-neoplastic conditions, was conducted in Italy. The subjects' usual diet was investigated through a validated and reproducible food frequency questionnaire. Multivariate odds ratios (ORs) and 95% confidence intervals (CIs) were obtained after allowance for energy intake and other potential confounding factors. RESULTS: A significant direct relation was observed between starch intake (OR 1.51, 95% CI 1.15 to 1.99 for highest quintile compared with lowest one), and an inverse relation was observed for polyunsaturated fatty acids (OR 0.72, 95% CI 0.55 to 0.93), linoleic acid (OR 0.73, 95% CI 0.56 to 0.94), and linolenic acid (OR 0.71, 95% CI 0.54 to 0.93). CONCLUSIONS: The results of this study suggest a role for specific macronutrients in the risk of BPH, including, in particular, an unfavorable effect for starch and a beneficial one for polyunsaturated fatty acids.

Type of alcoholic beverage and the risk of laryngeal cancer.

A few studies have investigated whether the risk of laryngeal cancer depends on the types of alcoholic beverage consumed, providing conflicting results. We investigated this issue using the data from two case-control studies conducted in Italy between 1986 and 2000. These included 672 cases of laryngeal cancer and 3454 hospital controls, admitted for acute, non-neoplastic conditions, unrelated to smoking and alcohol consumption. Significant trends in risk were found for total alcohol intake, with multivariate odds ratios (ORs) of 1.12 for drinkers of 3-4 drinks/day, 2.43 for 5-7, 3.65 for 8-11, and 4.83 for > 12 drinks/day, as compared to abstainers or light drinkers. Corresponding ORs for wine drinkers were 1.12, 2.45, 3.29 and 5.91. After allowance was made for wine intake, the ORs for beer drinkers were 1.65 for 1-2 drinks/day, and 1.36 for > or = 3 drinks/day, as compared to non-beer drinkers; corresponding values for spirits drinkers were 0.88 and 1.15. This study thus indicates that in the Italian population characterized by frequent wine consumption, wine is the beverage most strongly related to the risk of laryngeal cancer.

A pilot project of a cancer patient library in Italy: results of a customer-satisfaction survey and its products.

AIMS: The purpose of this study is to determine the degree of satisfaction of users of the Cancer Information Point section of the Library for Patients (CIP-LP), active since 1998 at the National Cancer Institute of Aviano, Italy. The CIP-LP is based on a skilled intermediary, adequate informative material and a specific location, within the Scientific Library of the Institute. PATIENTS AND METHODS: A survey was developed to assess service functionality and quality from the users' viewpoint. During a 6-month period, a questionnaire was mailed to 194 patients and relatives who previously used the CIP-LP; 113 (58%) were returned and processed. RESULTS: Of the respondents, 91% were pleased with the CIP-LP and 95% would recommend the service to other people. The information obtained contributed to a clearer understanding of the illness and treatment (45% as first answer) and a better control of the situation (33%). Fifty-one per cent evaluated the information received as 'good', 42%'excellent' and 4%'of sufficient quality'. CONCLUSION: This survey shows the appreciation and usefulness in the users' perception of a specific hospital library for cancer patients and their relatives, providing an information service supplementary to doctor-patient communication.

Family history of hemolymphopoietic and other cancers and risk of non-Hodgkin's lymphoma.

We investigated the risk of lymphomas, hemolymphopoietic (HLP) cancers (including lymphomas), and non-HLP cancers in first-degree relatives of non-Hodgkin's lymphoma (NHL) cases in an Italian case-control study on 225 patients (median age, 59 years) with a new diagnosis of NHL and 504 hospital controls (median age, 63 years), admitted for a wide spectrum of acute, nonneoplastic, nonimmune conditions. We estimated odds ratios (OR) adjusted for sex, age, family size, and other potential confounders. We also built the cohort of all first-degree relatives and computed age and sex adjusted hazard ratios (HR) using proportional hazard models. A history of lymphoma in first-degree relatives was reported by 5 NHL cases and 3 controls [OR, 3.2; 95% confidence interval (95% CI), 0.7-14.4] whereas 14 cases and 11 controls reported a family history of HLP cancers (OR, 3.0; 95% CI, 1.2-7.0). The HR of relatives of NHL cases, compared with relatives of controls, was 4.5 (95% CI, 1.1-18.8) for lymphomas, 3.5 (95% CI, 1.5-7.4) for HLP cancers, 1.6 (95% CI, 1.3-2.0) for all cancers, and 1.0 (95% CI, 0.9-1.1) for all causes of deaths. The HRs were higher for relatives of NHL cases diagnosed before the age of 50 years: 7.1 for HLP cancers, 2.0 for all cancers, and 1.6 for all deaths. A family history of cancer of the liver (OR, 2.1; 95% CI, 1.0-4.2), breast (OR, 2.0; 95% CI, 1.0-3.6), and kidney (OR, 4.6; 95% CI, 1.0-20.9) increased NHL risk. The OR was also elevated for all cancer sites (OR, 1.7 95% CI, 1.2-2.4) and the risk increased with the number of affected relatives also when HLP cancers were excluded.
