The decline in cancer mortality in the European Union, 1988-1996.

After the peak rate reached in 1988, moderate but steady declines were observed over the last decade in total cancer mortality rates in the European Union (EU). Such a decline was over 7% for both sexes combined over the period of 1988-1996 (i.e. from 147.0 to 136.4/100,000, world standard population). The declines in cancer mortality correspond to the avoidance of approximately 70,000 deaths in 1996 in the EU compared with the 1988 rates. The major determinants of these favourable trends were lung (-7.7%), stomach (-24.8%), intestines (-12.4%), breast (-7.1%), uterus, mainly cervix (-20.6%), and leukaemias (-8.3%) and, after 1992, a levelling off of prostate cancer rates.

Cervical cancer mortality in young women in Europe: patterns and trends.

On the basis of overall national death certification data, it is not possible to analyse mortality from cervical cancer in Europe, since 20-65% of deaths from uterine cancer in largest countries are still certified as uterus, unspecified. We analysed, therefore, age-standardised death certification rates from uterine cancer between 1960 and 1998 in women aged 20-44 years, since most deaths from uterine cancer below the age of 45 years arise from the cervix. In all Western European countries, except Ireland, substantial declines in cervical cancer mortality in younger women were observed, although the falls were larger and earlier for some Nordic countries. The trends were irregular in the UK, with earlier declines between 1960 and 1970, followed by a rise between 1970 and 1985, and a subsequent fall. In Ireland, mortality from uterine cancer at age 20 to 44 years has been rising since the early 1980s, to reach 3.4/100000 in 1995-1996. In Eastern Europe, some fall in mortality was observed in Hungary and Poland, while trends were upwards in Romania since 1980, and in Bulgaria. In all these countries, moreover, absolute rates remained appreciably higher than in most of Western Europe, and in the late 1990s there was over a 10-fold variation between the highest rates in Romania (10.6/100000 women aged 20-44 years) and the lowest ones in Finland (0.5/100000) or Sweden (0.9/100000). Within the European Union, the variation was over 6-fold, the highest rates being registered in Ireland (3. 4/100000) and Portugal (3.2/100000). The declines registered in cervical cancer mortality in young women were largely due to screening, and the persisting variations in mortality across Europe underline the importance of the adoption of organised screening programmes, with specific urgency in Eastern Europe.

A pooled analysis of thyroid cancer studies. V. Anthropometric factors.

OBJECTIVE: To assess the relation between anthropometric factors and thyroid cancer risk in a pooled analysis of individual data from 12 case-control studies conducted in the US, Japan, China and Europe. METHODS: 2056 female and 417 male cases, 3358 female and 965 male controls were considered. Odds ratios (OR) were derived from logistic regression, conditioning on age, A-bomb exposure (Japan) and study, and adjusting for radiotherapy. RESULTS: Compared to the lowest tertile of height, the pooled OR was 1.2 for females for the highest one, and 1.5 for males, and trends in risk were significant. With reference to weight at diagnosis, the OR for females was 1.2 for the highest tertile, and the trend in risk was significant, whereas no association was observed in males. Body mass index (BMI) at diagnosis was directly related to thyroid cancer risk in females (OR = 1.2 for the highest tertile), but not in males. No consistent pattern of risk emerged with BMI during the late teens. Most of the associations were observed both for papillary and follicular cancers, and in all age groups. However, significant heterogeneity was observed across studies. CONCLUSIONS: Height and weight at diagnosis are moderately related to thyroid cancer risk.

Wine drinking and diet in Italy.

OBJECTIVE: To investigate the relation between wine drinking and intake of selected indicator foods, which may vary in various populations. DESIGN: Cross-sectional analysis of the comparison group of a case- control study. SETTING: A network of teaching and general hospitals from six Italian areas. SUBJECTS: 5642 control subjects (3261 females and 2381 males) aged 20-74 y (median age 58 y), admitted for acute, non-neoplastic conditions unrelated to alcohol consumption. Participation rate was over 95%. INTERVENTION: Trained interviewers collected information using a structured and validated questionnaire. The average intakes of selected food items were computed, together with the multivariate odds ratios (OR) of eating above the median of each food. RESULTS: No appreciable difference in either sex for any food indicator considered (fruit, raw vegetables, cooked vegetables, salad and fish) was observed between abstainers, wine, and other alcoholic beverage drinkers. If anything, female wine drinkers reported less frequently high consumption of salad (OR=0.8) and raw vegetables (OR=0.8), both estimates being of borderline significance. CONCLUSIONS: In no instance did wine drinkers or mixed drinkers (who include a large proportion of wine drinkers, too) show an association with indicators of healthy diet.

Wine and other types of alcoholic beverages and the risk of esophageal cancer.

OBJECTIVE: To investigate the separate and combined effect of wine-drinking and other alcoholic beverages on esophageal cancer, in a high wine-consuming population. DESIGN: Combined analysis of two hospital-based case-control studies. SETTING: Major teaching and general hospitals in the greater Milan area and in the province of Pordenone, in northern Italy. SUBJECTS: A total of 714 incident cases of esophageal cancer, and 3137 controls admitted to hospital for acute, non-neoplastic conditions, unrelated to alcohol consumption. INTERVENTION: Trained interviews identified and questioned cases and controls using standardized structured questionnaires, including information on the average number of days per week each type of alcoholic beverages (wine, beer, spirits) was consumed, and the average number of drinks per day. Odds ratios (ORs) were calculated using unconditional multiple logistic regression equations. RESULTS: With reference to total alcohol drinking, as compared to non- or moderate drinkers (<3 drinks per day), the multivariate ORs were 1.98 for drinkers of 3-4 drinks per day, 4.22 for 5-7, 7.60 for 8-11, and 12.35 for > or =12 drinks per day. Higher risks were observed for wine-only drinkers and the corresponding values were 1.70, 4.21, 8.76 and 17.90. After allowance for wine intake, no association was observed between beer and spirit drinking and esophageal cancer, in a population in which 80% of alcohol came from wine. CONCLUSION: The amount of ethanol determines the risk of esophageal cancer, and the most commonly used alcoholic beverage appear to be most strongly associated.

Trends in mortality from leukemia in subsequent age groups.

Trends in age-standardized death certification rates from leukemias in subsequent age groups were analyzed on the basis of the World Health Organization database over the period 1960-1997 in the European Union (EU) and other developed areas of the world. In the EU, the peak rate at age 0-14 was observed in 1960-1964, and the fall in mortality was over 70%, to reach 1.2/100,000 males and 0.9/100,000 females in 1995-1997. In the age group 15-44, the fall was about 40% for males and 45% for females. In the age group 45-59, the fall was around 25%. At age 60-69, the peak rate was observed in the late 1970s, and the subsequent fall was only 6% for females. At age > or =70, leukemia mortality rose up to the late 1980s, and levelled off there-after. Overall, the falls in leukemia mortality over the 35-year calendar period corresponded to the avoidance of about 7,000 deaths per year. In eastern Europe, the falls in children and young adults started later --in the late 1970s--and were less than 40% for children and 30% for young adults (15-44 years). Overall age-standardized mortality from leukemia did not appreciably change over the 35-year period considered. Leukemia mortality rates in the USA and Japan started from different values, but were similar to those of the EU in the late 1990s, indicating that the impact of therapeutic advancements has been comparable in developed areas of the world. In eastern Europe, however, the declines in leukemia mortality were later and appreciably smaller.

Menopause and colorectal cancer.

Post-menopausal women who have never used hormone replacement therapy have a higher risk of colon, but not rectal, cancer than do premenopausal women of the same age, socio-cultural class and dietary habits. Such risk increase seems to last about 10 years and to be restricted to lean women, a group who have lower levels of oestradiol after ovarian function ceases after menopause.

Smoking and drinking cessation and the risk of oesophageal cancer.

In a case-control study from Italy and Switzerland with 404 oesophageal cancer cases and 1070 hospital controls, the risk of oesophageal cancer declined with time since cessation of smoking or drinking, and was significantly reduced (odds ratio = 0.11) 10 or more years after cessation of both habits.

Sex differences in colorectal cancer mortality in Europe, 1955-1996.

Colorectal cancer is the leading cancer in non-smokers in Western countries, and over the last decades its trends have been generally more favourable for women than for men. Possible explanations of the sex differentials in colorectal cancer relate to different exposure to exogenous hormones and to other risk factors including diet, physical activity and alcohol drinking. The objective of this investigation was to systematically analyse the trends in colorectal cancer mortality sex ratios in major European countries over the last four decades. Trends in death certification rates from colorectal cancer over the period 1955-1996 were analysed for 20 European countries (excluding the former Soviet Union and a few of the smaller countries). In all countries, the mortality sex ratios (M/F) were around or slightly above unity in the 1950s, and systematically increased to approach 1.5 in the 1990s. The extent of the rises varied across countries, ranging between + 0.8% in Germany, + 9.7% in Sweden, and + 12.1% in Denmark (the lowest increases) to + 65.3% in Spain, + 56.2% in Portugal, and + 50.4% in Hungary (the highest ones). Mortality sex ratios in Europe show more favourable trends for females, which may be attributable, in part, to the introduction of exogenous hormones in the late 1950s and 1960s, and, in part, to differential sex exposure to major environmental risk factors.

Fraction of prostate cancer incidence attributed to diet in Athens, Greece.

Diet appears to be a major determinant in the incidence of prostate cancer. In a case-control study conducted in Athens, Greece, we found that dairy products, butter and seed oils were positively associated with risk of prostate cancer, whereas cooked and raw tomatoes were inversely associated. We utilized the data from this study to calculate the population attributable fractions under alternative assumptions of feasible dietary changes. For each subject, a dietary score was calculated and categorized into approximately quintiles, representing increasing levels of prostate cancer risk as a function of the intake of the five discriminatory food groups or items. Population attributable fractions in terms of this dietary score were calculated taking into account multivariate adjustment. We observed that, if all individuals were shifted to the baseline category, the incidence of prostate cancer in this study population would be reduced by 41% (95% confidence interval 23-59%). However, if all individuals were shifted to the adjacent lower risk quintile, the expected incidence reduction would be a more modest 19%. The incidence of prostate cancer in Greece could be reduced by about two-fifths if the population increased the consumption of tomatoes and reduced the intake of dairy products, and substituted olive oil for other added lipids.

An age, period and cohort analysis of pleural cancer mortality in Europe.

Death certification data from pleural cancer in eight European countries providing data to the World Health Organization database over the period 1970-1994 were analysed using a log-linear Poisson model to disentangle the effects of age, birth cohort and period of death. The age effect reached values between 10 and 15/100,000 males at age 80-84 in most countries, except Hungary (6.7), Switzerland (18.0), France (20.6) and the Netherlands (36.5). Cohort effects were steadily and appreciably upwards in all countries up to the generations born in 1940 or 1945, and levelled off for the 1950 cohort, except in Hungary, where persistent rises were observed. Thus, most rises in pleural cancer mortality in Europe were on a cohort of birth basis. Since most pleural cases were asbestos-related mesotheliomas, and since asbestos has an early-stage effect on subsequent mesothelioma risk, exposure early in life is important for determining the subsequent mesothelioma risk of each generation. Consequently, the data indicate that the peak mortality from pleural cancer in most western European countries will be reached in the first decades of the 21st century, i.e. around 2010-2020, when the generations born between 1940 and 1950 will reach the peak age for mesothelioma incidence and mortality. This contrasts with US data, where the peak of pleural cancer incidence has been reached at the end of the 20th century, and reflects a delay in adopting adequate prevention measures since the 1940-1945 generations entered the workforce in the 1960s, when cancer risk from asbestos exposure was already recognized.

Risk factors for adenocarcinoma of the small intestine.

We have investigated the relation between alcohol, tobacco and dietary habits and risk of adenocarcinoma of the small intestine using data from 2 hospital-based case-control studies on intestinal cancers conducted in 6 Italian centres between 1985 and 1996. Cases were 23 patients below age 75 years with adenocarcinoma of the small intestine. Controls were 230 patients admitted to hospital for a wide spectrum of acute, non-neoplastic, non-digestive tract diseases, matched to cases on sex, age, study and centre. Odds ratios (ORs) were estimated using conditional logistic regression. Alcohol and tobacco consumption did not increase the risk of adenocarcinoma of the small intestine. The risk appeared to be directly related to intake of bread, pasta or rice (OR = 3.8), sugar (OR = 2.9) and red meat (OR = 4.6), and inversely to coffee (OR = 0.4), fish (OR = 0.3), vegetables (OR = 0.3) and fruit (OR = 0.6). Our results suggest that dietary correlates of adenocarcinoma of the small intestine are similar to those of colon cancer and at least of the same magnitude. While the present data are inconsistent with a major effect of tobacco or alcohol, a moderate association between these factors and small bowel cancer may have been obscured by the play of chance.
