Abstract
Ten case-control studies have been carried out in 6 European countries to investigate the major risk factors for lung cancer. Carcinogenic effect from cigarette smoke was the most relevant interest in our study, which has included 7,609 cases of lung cancer and 10,431 controls, mainly population based. The results indicate elevated odds ratios (ORs; 23.9 among men and 8.7 among women) with attributable risks exceeding 90% for men and close to 60% for women. A large, and statistically significant, variability of the results across countries was detected after adjusting for the most common confounding variables, and after controlling, at least in part, for the instability of the ORs due to the small number of non-smokers in some of the study subsets. This pattern of lung cancer risk associated with cigarettes smoke, across different European regions, reflects inherent characteristics of the studies as well as differences in smoking habits, particularly calendar periods of starting, and it is likely to have been influenced by effect modifiers like indoor radon exposure, occupation, air pollution and dietary habits.

Abstract
Reductive amination of 6-deoxy-6-formyl-beta-cyclodextrin with 5-(p-aminophenyl)-10,15,20-tris(p-sulfonatophenyl)porphyrin in the presence of an excess of sodium cyanoborohydride affords the hydrophilic cyclodextrin-porphyrin conjugate 3 in 23% yield. The structure of 3 was confirmed by NMR spectroscopy and mass spectrometry techniques. Compound 3 showed a marked tendency to dimerize in aqueous conditions via the formation of intermolecular porphyrin-cyclodextrin inclusion complexes and/or through electrostatic interactions. Information on the structure of these aggregates has been obtained by the use of circular dichroism and UV-vis spectroscopy. Aggregation can be avoided by the use of heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TM beta CD) that forms a 1:1 inclusion complex with compound 3.

Abstract
The association between cigarette smoking and lung cancer risk in women was investigated within the framework of a case-control study in 9 centres from 6 European countries. Cases were 1,556 women up to 75 years of age with histologically confirmed primary lung cancer; 2, 450 controls with age distribution similar to cases were selected. The predominant cell type was adenocarcinoma (33.5%), with similar proportions for squamous-cell type (26.4%) and small-cell carcinoma (22.3%). Overall, smoking cigarettes at any time was associated with a 5-fold increase in lung cancer risk (odds ratio 5.21, 95% confidence interval 4.49-6.04); corresponding figures for current smoking habits were 8.94, 7.54-10.6. The association showed a dose-response relationship with duration of the habit and daily and cumulative lifetime smoking. A significant excess risk of 70% was associated with every 10 pack-years smoked. After 10 years of smoking cessation, the relative risk decreased to 20% compared to current smokers. The following characteristics were associated with a higher relative risk: inhalation of smoke, smoking non-filter cigarettes, smoking dark-type cigarettes and starting at young age. The association was observed for all major histological types, being the strongest for small-cell type carcinoma, followed by squamous-cell type and the lowest for adenocarcinoma. The proportion of lung-cancer cases in the population attributable to cigarette smoking ranged from 14% to 85%. We concluded that women share most features of the association between cigarette smoking and lung cancer observed in men.

Abstract
We conducted a case-control study in 12 European study centers to evaluate the role of occupational risk factors among nonsmokers. We obtained detailed occupational histories from 650 nonsmoking cases (509 females/141 males) and 1,542 nonsmoking controls (1,011 females/531 males). On the basis of an a priori definition of occupations and industries that are known (list A) or suspected (list B) to be associated with lung carcinogenesis, we calculated odds ratios (ORs) for these occupations, using unconditional logistic regression models and adjusting for sex, age, and center effects. Among nonsmoking men, an excess relative risk was observed among those who had worked in list-A occupations [OR = 1.52; 95% confidence interval (C) = 0.78-2.97] but not in list-B occupations (OR = 1.05; 95%), CI = 0.60-1.83). Among nonsmoking women, there was an elevation of risk for list-A occupations (OR = 1.50; 95% CI = 0.49-4.53), although this estimate was imprecise, given that less than 1% of cases and controls were exposed. Exposure to list-B occupations was associated with an increase in relative risk (OR = 1.69; 95% CI = 1.09-2.63) in females, but not in males. Women who had been laundry workers or dry cleaners had an OR of 1.83 (95% CI = 0.98-3.40). Our findings confirm that certain occupational exposures are associated with an increased risk for lung cancer among both female and male nonsmokers; however, knowledge on occupational lung carcinogens is biased toward agents to which mainly men are exposed.

Abstract
To better understand the nutritional etiology of squamous cell esophageal cancer, we conducted a case-control study in 3 areas of northern Italy. A total of 304 incident, histologically confirmed cases of squamous cell carcinoma of the esophagus (275 men, 29 women) and 743 hospital controls (593 men, 150 women) with acute, non-neoplastic conditions, not related to smoking, alcohol consumption or long-term diet modification, were interviewed during 1992 to 1997. The validated food-frequency questionnaire included 78 questions on food items or recipes, which were then categorized into 19 main food groups, and 10 questions on fat intake pattern. After allowance for age, sex, education, area of residence, tobacco smoking, alcohol drinking and non-alcohol energy, a significant increased risk emerged for high consumption of soups (OR=2.1 for the highest vs. lowest quintile), whereas inverse associations with esophageal cancer risk were observed for pasta and rice (OR=0.7), poultry (OR=0.4), raw vegetables (OR=0.3), citrus fruit (OR=0.4) and other fruit (OR=0.5). The associations with dietary habits were consistent in different strata of tobacco smoking and alcohol drinking. Among added lipids, olive oil intake showed a significant reduction of esophageal cancer risk, even after allowance for total vegetable consumption (OR=0.4), while butter consumption was directly associated with this risk (OR=2.2). Our results thus provide further support to the evidence that raw vegetables and citrus fruit are inversely related to the risk of squamous cell esophageal cancer and suggest that olive oil may also reduce this risk.

Abstract
Glutathione S-transferase (GST) polymorphism may contribute to the individual variability in detoxifying lung carcinogens. This effect might be particularly relevant at low-level exposure to environmental carcinogens, such as in nonsmokers exposed to environmental tobacco smoke (ETS). We conducted a case-control study among 122 nonsmoking lung cancer cases and 121 nonsmoking controls from eight countries. Information on environmental exposures was obtained through a personal interview. The presence of GSTM1 and GSTT1 genes was determined using multiplex PCR. GSTM1-positive samples were then analyzed for *1A and *1B polymorphism using an allele-specific amplification-PCR method. GSTM1*2 (null) individuals had an odds ratio (OR) of lung cancer of 1.5 [95% confidence interval (CI), 0.9-2.7]; the risk associated with this genotype was higher for cases with squamous and small cell carcinomas (OR, 2.3; 95% CI, 0.9-6.1) than for cases with adenocarcinomas. It was also elevated in individuals with long-term exposure to indoor wood combustion (OR, 3.1; 95% CI, 0.9-9.9), in subjects who mainly lived in a rural setting (OR, 3.6; 95% CI, 1.0-13), and in cases exposed to occupational carcinogens (OR, 10.7; 96% CI, 0.4-260) but not in subjects exposed to ETS. GSTT1*2 subjects did not show a risk of lung cancer. Our study suggests that the effect of GSTM1 polymorphism in nonsmokers is similar to that found in smokers. It does not seem to interact with ETS exposure, although we cannot exclude that it does in association with exposure to other specific environmental carcinogens.

Abstract
The shape of the dose-response relationship between carcinogenic exposure and cancer risk is a key issue, both from a theoretical (models of carcinogenesis) and practical (risk assessment) point of view. Human populations exposed to Polycyclic Aromatic Hydrocarbons (PAH) via air pollution showed a non-linear relationship between levels of exposure and WBC-DNA adducts. Among highly exposed subjects, the DNA adduct level per unit of exposure was significantly lower than measured at environmental exposures. The same exposure-dose non-linearity was observed in lung DNA from rats exposed to PAH. We have analyzed 11 case-control studies on bladder cancer (4584 incident cases and 9360 hospital controls) and eight case-control studies on lung cancer (5092 incident cases and 6083 population controls), conducted in Europe in recent years. All the studies collected detailed information on smoking histories with a similar methodology. We have estimated the relationship between the number of cigarettes smoked and the risk of cancer, with and without adjustment by duration of smoking. We have observed a levelling-off of the relationship between the number of cigarettes smoked and the relative risks for lung and bladder cancer, both in men and women. The levelling-off occurred at an odds ratio of about 5 for bladder cancer, while it occurs at about 20 for lung cancer (in men). A potential explanation for such levelling-off involves metabolic pathways and individual susceptibility. It has been suggested that some metabolic polymorphisms exert an effect that is more important at low levels of exposure.

Abstract
Between 1992 and 1997 we conducted a case-control study of oesophageal cancer in 3 areas of northern Italy. Cases were 304 patients (29 women), ages 39-77 years (median age 60 years), with a first incident squamous-cell carcinoma (SCC) of the oesophagus. Controls were 743 patients (150 women), ages 35-77 years (median age 60 years), admitted for acute illnesses, unrelated to tobacco and alcohol, to major hospitals of the areas under surveillance. We derived estimates of daily dietary intake of 6 macronutrients, cholesterol, and 20 micronutrients or minerals from a validated food-frequency questionnaire, including 78 food groups and recipes and 15 questions on individual eating patterns. After allowance for age, gender, area of residence, education, body mass index, physical activity, smoking habit, alcohol consumption and energy intake, most micronutrients were inversely associated with oesophageal SCC risk. Highly significant associations emerged for monounsaturated fatty acids [odds ratio (OR) in highest vs. lowest intake quintile = 0.5]; carotene (OR = 0.3); lutein + zeaxanthin (OR = 0.4); vitamin C (OR = 0.4); and niacin (OR = 0.5). Only retinol appeared to be positively related to risk (OR = 1.9). The effect of the above nutrients, expressed as ORs, appeared to be similar in non-smokers and smokers, and non/light drinkers and heavy drinkers.

Abstract
Esophageal cancer is generally characterised by relatively low incidence and mortality rates in Europe. However, a high-risk population for this tumour is resident in the north-east of Italy. Several studies have been conducted on this population of males confirming the major role of alcohol and tobacco consumption alone and in combination. The inhabitants of this area of Italy constitute an ideal target population for studies of molecular epidemiology aimed at elucidating the natural history of the disease which is still ill-defined, and the distribution of genetic alterations at a population level.

Abstract
Between 1992 and 1997, we conducted a case-control study of oesophageal cancer in 3 areas of northern Italy. Cases were 275 men, ages 39-77 years (median age 60), with a first incident squamous-cell carcinoma of the oesophagus. Controls were 593 men, ages 36-77 years (median age 60) admitted for acute illnesses, unrelated to tobacco and alcohol, to major hospitals of the areas under surveillance. Number of daily cigarettes was strongly associated with risk [odds ratio (OR) for > or =25 cigarettes/day = 7.0)]. Long-duration smoking showed particularly elevated ORs (OR = 6.4 for > or =35 years), and excess risk declined after smoking cessation (OR = 1.5 after > or = 10 years). Oesophageal cancer risk steeply rose with increasing level of alcohol consumption. ORs were 6.2 for 35-55 drinks and 24.5 for 84 drinks or more per week. No trend in risk emerged for duration of alcohol drinking or age at start of drinking. The risk in the highest joint level of alcohol drinking and current smoking was increased 130 folds (i.e., compatible with a multiplicative model). Excess risk in drinkers chiefly derived from wine. In conclusion, alcohol drinking and cigarette smoking were both important, but the roles of dose and duration of exposure differed. The association with alcohol was stronger than the one with smoking by exposure intensity, but apparently unaffected by duration or other temporal variables.

Abstract
Populations resident in the historical town of Venice and in the inland industrial city of Mestre are at different risk of exposure to environmental pollutants. This case-control study compares the risk of developing lung cancer in the two populations in relation to known risk factors for this neoplasm. A retrospective study of 305 incident cases of lung and 447 frequency-matched population controls was conducted through a standard questionnaire on main risk factors for lung cancer. Completeness of cases was checked against the Venetian Cancer Registry files. The results indicate that lung cancer risk associated with tobacco smoking was high in both areas, although more elevated in Venice islands among heavy smokers. An elevation of risk was associated with housing without a heating system, possibly suggesting a role of worse hygienic conditions. An increased risk associated with exposure to occupational carcinogens was detected in the inland area. In conclusion, lung cancer risk due to tobacco smoking largely affects both the populations, while other risks such as occupation or housing conditions appear to be more population-specific.

Abstract
Several studies in the past have shown appreciably higher lung cancer risk estimates associated with smoking exposure among men than among women, while more recent studies in the USA report just the opposite. To evaluate this topic in a European population we conducted a case-control study of lung cancer in three German and three Italian centres. Personal interviews and standardized questionnaires were used to obtain detailed life-long smoking and occupational histories from 3723 male and 900 female cases and 4075 male and 1094 female controls. Lung cancer risk comparing ever-smokers with never-smokers was higher among men (odds ratios (OR) adjusted for age and centre = 16.1, 95% confidence interval (CI) 12.8-20.3) than among women (OR = 4.2, CI 3.5-5.1). Because the smoking habits of women were different from men, we conducted more detailed analyses using comparable levels of smoking exposure. After restriction to smokers and adjustment for other smoking variables, risk estimates did not differ appreciably between genders. The analysis of duration of smoking (0-19, 20-39, 40+ years) adjusted for cigarette consumption and time since quitting smoking revealed similar risk estimates in men (OR = 1.0, 3.3 [CI 2.6-4.2], 4.1 [CI 3.1-5.6]) and women (OR = 1.0, 2.7 [CI 1.7-4.1], 3.3 [CI 1.9-5.8]). The same was true of the analysis of average or cumulative smoking consumption, and also of analyses stratified by different histological types. We conclude that for comparable exposure to tobacco smoke, the risk of lung cancer is comparable in women and men.

Abstract
We conducted a case-control study of adenocarcinoma of the lung and exposure to environmental tobacco smoke (ETS) in 7 countries. We interviewed 70 cases of adenocarcinoma of the lung and 178 population or hospital controls. All subjects had smoked fewer than 400 cigarettes in their lifetimes. Ever exposure to ETS from the parents during childhood was associated with a decreased risk [odds ratio (OR) 0.6, 95% confidence interval (CI) 0.3-1.2], and there was a suggestion of a decreasing trend in risk with increasing duration of exposure. Ever exposure to ETS from the spouse was not associated with an increased risk (OR 1.0, 95% CI 0.5-1.8), while the OR of ever exposure to ETS at the workplace was 1.5 (95% CI 0.8-3.0). For both exposure sources, an increased risk was observed among the highly exposed, and the OR among those with the highest duration of exposure to ETS from the spouse or at the workplace was 1.8 (95% CI 0.5-6.2). A similar risk was estimated for current exposure to ETS from either source. Our results confirm previous reports of a weak effect of adult ETS exposure on risk of adenocarcinoma of the lung. Bias and confounding cannot be excluded as explanations for the apparent decrease in risk from childhood exposure.

Abstract
Cancer registration took place in Italy in the first half of the Seventies with only one Cancer Registry in the province of Varese. More recently several cancer registries started their activity attaining population coverage of approximately 18% of the national population. The contribution from a network of cancer registries in Italy to the activity of cancer research and control is discussed in view of an improved exploitation of this tool.

Abstract
BACKGROUND Because limited information is available on the quantitative association between consumption of tobacco products other than cigarettes and lung cancer risk, we undertook a case-control study of this relationship. METHODS We investigated lung cancer risk among smokers of cigars and/or cigarillos only and of pipes only and compared these risks with the risk of smokers of cigarettes only in a case-control study conducted in seven European areas. Our study population consisted of 5621 male case patients with lung cancer and 7255 male control subjects. Each subject or his proxy was interviewed with respect to the subject's smoking history and other risk factors for lung cancer. RESULTS The odds ratio (OR) for smoking cigars and cigarillos only was 9.0 (95% confidence interval [CI] = 5.8-14.1), based on 43 exposed case patients and 77 exposed control subjects, and the OR for smoking a pipe only was 7.9 (95% CI = 5.3-11.8), representing 61 case patients and 129 control subjects. The OR for smoking cigarettes only was 14.9 (95% CI = 12.3-18.1), based on 4204 case patients and 3930 control subjects. A dose-response relationship was present for duration of use and cumulative consumption both for cigars and cigarillos and for pipe tobacco. An effect was also suggested for inhalation of cigar and cigarillo smoke. The dose-response relationships between lung cancer risk and either duration of smoking or average and cumulative consumption were similar for cigar and cigarillo smoking, pipe smoking, and cigarette smoking. CONCLUSION Our results suggest that smoking of European cigars, cigarillos, and pipe tobacco might exert a carcinogenic effect on the lung comparable to that of cigarettes.

Abstract
BACKGROUND An association between exposure to environmental tobacco smoke (ETS) and lung cancer risk has been suggested. To evaluate this possible association better, researchers need more precise estimates of risk, the relative contribution of different sources of ETS, and the effect of ETS exposure on different histologic types of lung cancer. To address these issues, we have conducted a case-control study of lung cancer and exposure to ETS in 12 centers from seven European countries. METHODS A total of 650 patients with lung cancer and 1542 control subjects up to 74 years of age were interviewed about exposure to ETS. Neither case subjects nor control subjects had smoked more than 400 cigarettes in their lifetime. RESULTS ETS exposure during childhood was not associated with an increased risk of lung cancer (odds ratio [OR] for ever exposure = 0.78; 95% confidence interval [CI] = 0.64-0.96). The OR for ever exposure to spousal ETS was 1.16 (95% CI = 0.93-1.44). No clear dose-response relationship could be demonstrated for cumulative spousal ETS exposure. The OR for ever exposure to workplace ETS was 1.17 (95% CI = 0.94-1.45), with possible evidence of increasing risk for increasing duration of exposure. No increase in risk was detected in subjects whose exposure to spousal or workplace ETS ended more than 15 years earlier. Ever exposure to ETS from other sources was not associated with lung cancer risk. Risks from combined exposure to spousal and workplace ETS were higher for squamous cell carcinoma and small-cell carcinoma than for adenocarcinoma, but the differences were not statistically significant. CONCLUSIONS Our results indicate no association between childhood exposure to ETS and lung cancer risk. We did find weak evidence of a dose-response relationship between risk of lung cancer and exposure to spousal and workplace ETS. There was no detectable risk after cessation of exposure.

Abstract
OBJECTIVE To analyse trends of avoidable mortality in Europe, emphasising causes of death amenable to primary prevention through reduction of exposures, secondary prevention through early detection and treatment, and tertiary prevention through improved treatment and medical care. DESIGN Descriptive study of mortality from avoidable causes for the years 1955 through 1994, for ages 5-64 at time of death. Using the World Health Organisation Mortality Database, five year death rates were standardised to the world population. SETTING 21 countries of Europe in four regions (northern, central, and southern Europe, Nordic countries). PARTICIPANTS All causes of deaths for men and women, aged 5-64, at time of death. MAIN RESULTS Between 1955-59 and 1990-94, the reduction in mortality was somewhat greater for avoidable causes than for all causes: 45.8% v 45.1% (women) and 39.3% v 32.6% among men. Reductions in mortality were greater for causes amenable to improved medical care: 77.9% among women and 76.3% among men. The smallest reduction in mortality was seen in women for causes amenable to secondary prevention (11.0%), and in men for causes amendable to primary prevention including tobacco related conditions (16.6%). From a geographical point of view, there were slight differences in trends between European regions, but overall the patterns were similar. CONCLUSIONS The greatest reduction of avoidable mortality in Europe from 1955-94 came from causes amenable to improved treatment and medical care for both sexes. Further reductions of avoidable mortality can be achieved through implementation of primary and secondary prevention activities, such as tobacco control, reduction of occupational exposures, and universal access to breast and cervical cancer screening programmes.

Abstract
Record linkage was carried out between the national Registry of AIDS and 13 Cancer Registries (CRs) covering, in 1991, about 15% of the Italian population. Observed and expected numbers of cancers and standardized incidence ratios (SIRs) were assessed in 6067 persons with AIDS, for a total of 25,759 person-years. Significantly increased SIRs were found for Hodgkin's disease [8.9, 95% confidence interval (CI) 4.4-16.0], in which seven of 11 cases were of mixed cellularity type; invasive carcinoma of the cervix uteri (15.5; 95% CI 4.0-40.1); and non-melanomatous skin cancer (3.0, 95% CI 1.3-5.9), in which five of eight cases were basal cell carcinoma. An excess was also seen for brain tumours, but this may be partly due to misdiagnosis of brain non-Hodgkin's lymphoma or other brain diseases occurring near the time of the AIDS diagnosis. The risk for all cancer types, after exclusion of Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL), was approximately twice the general population risk. An increased SIR for Hodgkin's disease in persons with AIDS is thus confirmed, though it is many times smaller than that for NHL. An association with invasive carcinoma of the cervix is also shown at a population level. The excess of non-melanomatous skin cancer seems to be lower than in transplant recipients.
