Comparisons of colon-cancer survival among European countries: The Eurocare Study.

Under the aegis of EUROCARE, a European Union project to assemble survival data from population-based cancer registries and analyze them according to standardized procedures, we have investigated and compared colon-cancer survival in 10 European countries. We analyzed 68,283 colon-cancer cases diagnosed between 1978 and 1985 and followed for at least 6 years. After calculating relative survival, putative factors prognostic for survival were investigated by univariate and multiple-regression analyses. Important intercountry colon-cancer survival differences exist within Europe, which are not explained by methodological differences, nor by demographic confounders. In patients aged 60 to 69, the mean European 5-year cumulative relative survival was 40%. Switzerland, Finland and The Netherlands had significantly higher 5-year relative survival, while one area in the UK and Cracow in Poland had significantly lower survival than this European estimate. Prognosis improved over time: from 1978 to 1985, the risk of death was reduced by about 4% per year in all countries studied. Age at diagnosis is inversely related to prognosis. Differences in health provision and hence in quality of care and stage at presentation seem largely responsible for the differences in colon-cancer survival found in the EUROCARE countries.

Epidemiology of gallstone disease in Italy: prevalence data of the Multicenter Italian Study on Cholelithiasis (M.I.COL.)

This study was designed to obtain a general overview of gallstone disease in Italy. A total of 18 cohorts in 10 Italian regions were enrolled in this survey. Four cohorts were excluded from analysis because of a participation rate of less than 50 percent. Field activities started in December 1984 and terminated in April 1987. A precoded questionnaire was administered to each subject by a trained member of the medical staff. Participants underwent an ultrasonographic examination of the upper abdomen and blood sampling. Each research group was provided with an identical ultrasonographic machine. Standardized criteria were established for both the examination and diagnosis. The inter- and intraobserver variation in the ultrasonographic procedure was assessed using a reliability study. The overall kappa score for interobserver agreement was good (0.649), while intraobserver agreement was good or excellent (kappa scores > 0.60) in 75 percent of the observers. A total of 29,739 of the 46,139 (64.4 percent) enrolled subjects were examined. Among those with a clear-cut definition of the gallbladder status, 6.5 percent of the males and 10.5 percent of the females had gallstones. Additional 3.0 and 8.4 percents, respectively, had already undergone cholecystectomy. Prevalence of gallstone disease (gallstones plus cholecystectomy) increased linearly with age in both sexes. Among subjects with gallstones, 76.7 percent of men and 72 percent of women were not aware of having gallstones; 87.0 percent of men and 84.9 percent of women were asymptomatic. This study confirms that gallstone disease is a highly prevalent condition. Gallstones rarely cause symptoms, and subjects are mostly unaware of their presence.

Estimation and projections of stomach cancer trends in Italy.

Mortality data from official sources, and survival data from population-based cancer registries, are used for the estimation of incidence and prevalence of stomach cancer. Time trends of morbidity, survival, and mortality during the period 1970-90 are presented and analyzed. Incidence rates were decreasing during the considered period, but the rate of decrease was slowing down during the last decade. Almost stable rates, and even slightly increasing for women, were estimated for the youngest cohorts. Relative survival for stomach cancer was higher for women and for young ages; it was associated positively with period of diagnosis, and presented a significant South-North geographic gradient. Prevalence was estimated as decreasing during the period 1970-80, but increasing during the successive decade, due to both better survival and population aging. Projection of stomach cancer morbidity and mortality to the year 2000 showed that the disease should still be considered in Italy as a major public health problem.

Cancer mortality in migrant populations within Italy.

METHODS. Mortality rates for four types of cancer (stomach, colorectal, lung, and breast cancer) in migrant populations were compared to those of individuals who still resided in the political region in which they were born. The effects on mortality rates of place of birth and of place of residence were studied, comparing different regression models. RESULTS. Overall, people who were born in the South and who later migrated had significantly higher mortality rates than the southern population, but lower than the population in the area of residence, for most cancers. Place of birth and place of residence showed different power in explaining the observed mortality rates for different cancer sites: place of birth was a stronger predictor for stomach and breast cancers, while residence was a stronger predictor for lung and colorectal cancers. The status of 'migrant' was found to be an overall risk factor. The compatibility of the results obtained with different aetiological hypotheses is discussed.

Time trends of lung and larynx cancers in Italy.

During the period 1970-1989, age-adjusted mortality rates for lung cancer in Italy increased by more than 50%, while rates for larynx cancer in males decreased by approximately 13%. This study aims to interpret this difference, which seems to contradict the finding that cigarette smoking is a common major risk factor for both lung and larynx cancer. To this end, we jointly analyzed the time trends of incidence, survival and mortality. We first examined survival data taken from the population-based Lombardy Cancer Registry (northern Italy). Based on data referring to 880 incident cases of larynx cancer, diagnosed during the period 1976-1987, we estimated a 3% annual increase in relative survival. By contrast, no significant period effect was observed for survival rates of 2,259 incident cases of lung cancer. National incidence rates were estimated using official mortality data and the above-described survival data. Age-adjusted estimated incidence rates increased, from 1970 to 1989, for both cancer sites: +55% for male lung, +56% for female lung, and +22% for male larynx. Moreover, the patterns of birth-cohort effect, which are diverging for mortality, are nearly parallel with regard to incidence. This analysis suggests that a substantial improvement in survival of larynx cancer patients may largely explain the differences in mortality trends for cancer of lung and larynx.

An age and period reconstruction of the HIV epidemic in Italy.

BACKGROUND: The majority of AIDS cases in Italy are among intravenous drug users (68%) and homosexual men. An age, period and cohort (APC) model is presented and used to reconstruct the HIV epidemics in Italy. Projections of AIDS-related conditions (ARC) and AIDS cases are attempted based on a hypothesis of minima and an endemic hypothesis. METHODS: The model is a generalization of the usual back-calculation method which considers age, competitive mortality, susceptible population and therapy effects. Estimates of the HIV epidemic in Italy are obtained using Italian AIDS counts (corrected for delay in reporting), and an incubation time distribution (estimated from data of an Italian cohort), which was found to be dependent on the age at infection. The impact of AZT therapy, introduced in Italy in mid1987, is evaluated using a modification of the incubation time distribution dependent on period of infection. RESULTS: The estimated number of new infections in Italy declined after 1987, although the number of new AIDS cases has continued to rise, albeit less steeply in recent years. When delay in the progression to AIDS due to therapy is taken into account, the estimated number of people infected in mid1990 increases from 52,000 to 67,000, with approximately 12% of subjects already in the ARC stage. The age at maximum risk of infection is 25 years in males and 23 years in females. CONCLUSIONS: Using a hypothesis of no more HIV infections after 1990, AIDS counts would be still rising in Italy up to 1993 as a result of past infections and of the long incubation period.

Relationships between incidence and mortality in non-reversible diseases.

The estimation of the incidence of chronic diseases from mortality and survival rates is shown to be attainable, under some simplifying hypotheses, through the solution of a convolution equation. Exact solutions are derived for the cases in which survival times of incident cases are exponential or gamma distributed. Applications to breast cancer, HIV infection and stomach cancer incidence in the Italian population are presented.

Trends in lung cancer mortality in three broad Italian geographical areas between 1969 and 1987.

Trends in death certification rates from lung cancer in broad Italian geographical areas (north/centre/south) were analysed over the period 1969-1987. In northern Italy, lung cancer rates in young and middle-aged males reached a peak between the mid and late 1970s, and tended to decline afterwards; only above age 60 was mortality still rising in the 1980s. A similar pattern of age-specific rates was observed in central areas, while in the South rates tended to level off in the early 1980s only below age 55, but were still upwards in subsequent age groups. Consequently, the north/south ratio for the overall age-standard rate increased slightly between the late 1960s and mid 1970s, from 1.68 (corresponding to a world standardised rate of 47.1/100,000 in the north vs. 28.1 in the south) to 1.73, but declined to 1.55 between 1985 and 1987 (for a rate of 69.1/100,000 males in the north vs. 44.6 in south). In the younger age groups a diverging pattern was observed: at ages of 25-34 rates in 1985 and 1987 were apparently higher in the south (1.0 vs. 0.9/100,000 in the north), and in the 35-44 age group the north/south ratio decreased from 1.7 to 1.2 (with rates of 12.9 and 10.7, respectively, in 1985 and 1987). Among females, lung cancer rates increased in all geographical areas and age groups except the youngest (25-34 years). Under the age of 50, the rises were proportionally similar in various geographical areas, thus widening the north/south difference in absolute terms. Above the age of 50, the north/south difference tended to be wider in relative terms too, reaching a factor of 2 in the 65-74 age group. The overall age-standardised north/south ratio for females increased from 1.51 in 1969-1974 (5.6 vs. 3.7/100,000) to 1.87 in 1985-1987 (8.4 vs. 4.5/100,000). These trends reflect changes in smoking habits in subsequent generations of Italian males and females from different areas of the country, and confirm the central role of cigarette smoking in lung cancer rates in various populations, although this does not exclude some influence by other, mainly occupational, lung carcinogens on the substantial differences in lung cancer rates in various Italian geographical areas.

Estimated incidence and prevalence of female breast cancer in Italian regions.

Female breast cancer incidence and prevalence in Italy have been estimated by region and vast areas from population-based survival data of breast cancer patients and 1970-1987 specific mortality data using a mathematical model. Italian age-standardized incidence rates (ASR) for 1987 range from 70 to 90 per 100,000 women-year in the Northern regions, 55 to 73 in the Center, and 45 to 72 in the South. Overall, the ASR is about 80 in the North, 70 in the Center and 60 in the South. In the absence of competitive mortality, breast cancer cumulative risk in the 0-74 years life span is about 7 women out of 100 in the North, 6 in the Center and 5 in the South. The decreasing risk pattern from North to Center then South appears less evident when under 45 age-specific rates are considered. Very high levels for young age-groups are present both in the North (Liguria and Emilia Romagna) and South (Sardinia and Apulia). The incidence pattern by age differs from region to region and over the considered period, suggesting that a birth-cohort effect is crossing the whole country. Using to model, it can be estimated that the risk by cohort increases from the generations born at the beginning of the century to those born in the 40s, after which, for subsequent generations, it has been decreasing in all the considered areas and is similar in the North and South. We can infer that for the whole country the incidence will increase up to the years 2000-2010 when those birth-cohorts at higher risk will also be at higher risk for age. In 1987, about 250,000 Italian women had a present or past history of breast cancer: for the 1970-1987 period, prevalence has increased by approximately 5,500 cases per year.

Age Factors

Survival for lung cancer in northern Italy.

From the population covered by the Lombardy Cancer Registry (northern Italy), all 2,259 lung cancer patients diagnosed from 1976 to 1981 were followed through 30 November 1989. The length of follow-up ranged from eight to 13 years. A special investigation on long-term survivors showed that a negligible proportion (0.01 percent) of errors occur in determining life status when an active follow-up is adopted. Age, stage, and histotype were found to be statistically significant, independent, prognostic factors in multivariate analysis both by the Cox model and by a model considering the relative survival. Observed survival was 29 percent at one year after diagnosis, 13 percent at two years, eight percent at three years, five percent at five years and two percent at 10 years. Survival decreased with age, but the youngest patients of both sexes showed lower survival compared with immediately subsequent ages. Among morphologically confirmed tumors, epidermoid carcinomas and adenocarcinomas showed the highest survival (38 percent and 33 percent at one year, respectively); small cell carcinomas showed the poorest prognosis (one-year survival, 23 percent). Beyond the second year after diagnosis, differences between histotypes became slighter. Survival according to stage showed a decreasing pattern from limited to advanced tumors, one-year figures being 41 percent for localized tumors, 27 percent for regional metastasis, and three percent for distant metastasis. Relative survival in Varese was compared with that reported by other cancer registries in Western countries: the variability noted could be related to different modalities of registration and to different distribution of clinical and demographic factors.

[Trends in mortality from respiratory tract tumors in Italy, 1969-1987].

Trends of Italian death certification for cancers of the lung, larynx, pleura and nasal sinuses were analyzed for both sexes in the period from 1969 to 1987. For lung and laryngeal cancer, the analyses have been conducted for broad geographical areas within Italy (North, Center and South). Mortality rates for males aged 35-44 years consistently decreased in the North; increased until the late 1970's, and then decreased in the Center; and consistently increased in the South. In the 45-54 age group, mortality rates peaked in all areas between the late 1970's and the early 1980's, subsequently decreasing. For ages over 54 years, the rates continued to increase even in the 1980's. Female lung cancer rates increased in all areas and in all age groups over 35 years. In the 25-34 years old age group the rates decreased in the North and tended to increase in the Center and in the South. Below age 50, the increases were proportional in the three areas, while for older ages the increase was greater in the North both in absolute and proportional terms. Cohort effects showed a general increase for the generations born up to 1930, in both sexes and in all geographical areas. Different trends were observed for cohorts born after 1940: decreasing for both sexes in the North, and steady for men and increasing for women in the other areas. From the mid 1970's, laryngeal cancer standardized rates for 35-64 age group decreased, or at most remained constant, in all geographical areas. The decreasing tendency was more marked in men. Larynx cancer cohort effects for men were at a maximum for cohorts born around 1990, decreasing thereafter. In women, cohort effects appeared to consistently decrease. Overall rates of pleural cancer mortality increased during the period 1969-1987, and the sex ratio was stable, from 1980 onwards, at a value of about 2.4. Cohort effects showed, for pleural cancer, a general increase for all the cohorts. The increase was particularly apparent in male cohorts born after 1930. Overall mortality rates for cancer of the nasal sinuses was rather stable in both sexes from 1975 onwards. However, in the 35-64 year age group, mortality rates increase for males and decreased for females.

[Incidence and prevalence of respiratory tumors in Italy. Estimation from mortality data].

This study estimates the incidence and prevalence of larynx and lung cancers using a mathematical model based on available data on specific mortality and survival. In Italy, larynx and lung cancers account for more than 95% of respiratory cancers. In this paper, estimates of age/sex-specific and age-standardized incidence rates and prevalence are presented for the years 1970 and 1987. Age and birth-cohort effects on incidence are also presented by sex and broad geographical area. The procedure was firstly validated using data from four cancer registries: Varese (Northern Italy), Parma (North-Central Italy), Florence (Central Italy), and Ragusa (Southern Italy). Estimates were then carried out at the national level and for each major geographical area (i.e. North, Center and South). Larynx cancer age-standardized incidence rates increased for men by about 25% from 1970 to 1987. Age-specific rates increased for ages greater than 44 years, but decreased for younger ages. Cohort effects are low for older cohorts; they steeply increase and plateau for the 1900-1905 cohorts, and then peak for the 1930 cohort. The risk for cohorts born after 1930 systematically decreases. We estimated that the 1930 birth cohort has a risk five times higher than the 1890 cohort. For women, the incidence rates increased by about 30% from 1970 to 1987, for all age classes. Cohort effects steadily increase from the 1886 birth cohort to the 1960 cohort. The estimated prevalence between ages 30 and 84 increased from about 24,400 cases in 1970 (23,000 males and 1,400 females) to about 51,400 cases in 1987 (48,600 males and 2,800 females). For men, 42% of the increase can be attributed to an increase in the incidence of the disease; 45% can be attributed to population aging, and only 13% to an increase in the survival probability. Corresponding figures for women are 42%, 48%, and 10%. For lung cancer, we estimated 32,000 incident cases for 1987 (28,000 men and 4,000 women), two times the corresponding figures for 1970 (14,000 men and 2,000 women). Looking at age-adjusted rates, the overall risk of lung cancer increased by about 60% for men and 52% for women during a period of 17 years. Age-specific incidence rates increased proportionally with age for ages greater than 50 years. By contrast, there was a slight but systematic risk reduction in younger age classes.(ABSTRACT TRUNCATED AT 400 WORDS)

Survival and age at diagnosis of breast cancer in a population-based cancer registry.

From the population covered by the Lombardy Cancer Registry, Italy, 1991 female breast cancer patients diagnosed from 1976 to 1981 were followed up until May 1987. Relative survival was 69% at 5 years and 58% at 10 years; median survival was 8.8 years. Ages 40-49 showed the best survival; ages 25-34 were 20% lower. From age 50 onwards, survival decreased progressively, with the exception of age group 65-74. We suggest that the best prognosis for ages 40-49, followed by the survival fall in subsequent ages, could be related to an anticipation of diagnosis in ages near menopause. The death hazard function showed a bimodal pattern, with a first peak in the first years after diagnosis, and a second one between the seventh and eighth years. The death hazard rate decreased by about 1% per year at each subsequent calendar year of diagnosis. When such an estimated calendar effect was taken in account, there were no considerable survival differences among Western countries covered by population-based cancer registries.

[Problems of codification of cause of death: comparison of the mortality data of the ISTAT and the Regional Mortality Registry of Tuscany].

A two-part study was undertaken to assess the comparability of the coding of underlying cause of death between ISTAT (Central Statistics Office providing "national" mortality statistics) and RMR (Mortality Registry of Tuscany Region providing "local" mortality statistics). In Part I was compared mortality data of the Province of Florence (years 1985-1986) from the files of ISTAT with those of RMR. The source of the cause of death is the same for both systems (ISTAT certificate), but the data collection and coding of RMR are different from those of ISTAT. In Part II was compared a set of 219 Tuscany death certificates (year 1988) coded by ISTAT and RMR. The results showed an high degree of completeness of RMR (only--0.65% vs. ISTAT) and a satisfactory level of correspondence in the number of deaths for circulatory diseases, for neoplasms and for cancers of most important sites (lung, stomach, intestine, pancreas, breast). Discrepancies were found for some other diseases; for some of these causes of death, also age-adjusted mortality rates showed discrepancies (for example ischaemic heart disease). The cause of these differences have been analyzed.

Breast cancer incidence and prevalence estimated from survival and mortality.

Survival probability for female breast cancer patients was used to estimate incidence rates from breast cancer mortality data in Italy. The female breast cancer survival curve from the Lombardy Cancer Registry (LCR) was used to test the method on data from four local cancer registries, covering areas in different regions of Italy. In spite of the well known geographic variability of female breast cancer incidence and mortality, the results support the idea that survival probability does not change across the country and that the survival probability from the LCR is a good estimate of that in the country as a whole. Female breast cancer incidence and prevalence rates were then estimated for Italy, making use of a mathematical model specifically developed for chronic diseases. In 1985, crude incidence and prevalence rates of female breast cancer, for ages up to 74 years, were estimated as 71 and 701 per 100,000 women, respectively. Estimated incidence rates show a complex trend with age, increasing to a temporary pronounced peak at the age of 52. A marked cohort effect was found to increase significantly the risk of the disease from the 1886 to the 1930 birth cohorts by a factor of 2.9. After the 1930 cohort, risks have continued at a constant high level.

Life expectancy in Italian track and field athletes.

Nine hundred eighty-three top Italian track and field athletes (700 males and 283 females) were examined for survival, mortality and causes of death for an average follow-up period of 18.6 years starting from their last year of competition as members of the national team. Overall mortality rates were compared to the rates expected on the basis of the life tables for Italian people of the same age, sex and time period. Thirty-four deaths were observed among males (vs 46.6 expected) with a O/E ratio of 0.73, while 3 deaths were observed among women (vs 6.2 expected) with a O/E ratio of 0.48. Neither of these differences was significant, but the O/E ratio for the group as a whole was quite significant (p = 0.0296). Some of the athletes demonstrated behavioural characteristics developed during their active careers that might have contributed to their low mortality rate.
