Recent trends of in situ carcinoma of the breast and mammographic screening in the Florence area, Italy.

OBJECTIVES: The study analyzes the relationship between the incidence trends of breast carcinoma in situ (CIS) and the spread of mammography screening in the Italian area of Florence (about 608,000 female residents). SETTING: In this area, since the seventies, a mammographic screening by personal invitation was performed by the Center for Cancer Prevention (CSPO) in some rural municipalities. After 1990, the municipality of Florence and other municipalities were involved in the screening. METHODS: The study included all cases of female breast carcinomas in situ reported to the population-based Tuscany Cancer Registry between 1985 and 1995. On the basis of information from the CSPO files, the cases were categorized into: "screen-detected", "self-referrals", and "other" (CSPO cases diagnosed in symptomatic women or at periodic check up after breast cancer plus hospital cases). RESULTS: Overall, 332 women with breast carcinoma in situ (CIS) were registered between 1985 and 1995. The CIS incidence rate increased from 2.39/100,000 women in 1985-87 to 6.22/100,000 in 1994-95. The largest increase was observed for the ductal carcinoma in situ (2.9 times) and in women aged 50-69 years (3.8 times). In this age group, cases diagnosed at the screening by personal invitation accounted for 69% of the rise in CIS incidence. The proportion of mastectomy lowered from 41% before 1990 to 25% after 1990. CONCLUSION: In the Florence area the CIS incidence trend, showing a marked increase beginning in 1991, was mainly explained by the spread of the mammographic screening by personal invitation. The period during which mammographic screening became widespread coincided with a change in the treatment policy of breast cancer, with a high proportion of breast conserving surgery also for CIS. Therefore, the rise in CIS incidence rates correlated with the widespread use of mammographic screening did not substantially increase the number of women treated by mastectomy.

Fibrinogen and mortality in chronic critical limb ischaemia.

OBJECTIVE: Plasma fibrinogen predicts cardiovascular events in patients with stable peripheral arterial occlusive disease, but its predictive value in patients with chronic critical limb ischaemia, a condition associated with a high risk of death, is unknown. DESIGN: A prospective cohort study. SETTING: Determination of fibrinogen and other potential predictors during clinic-based work-up of patients admitted for diagnostic and therapeutic evaluation. SUBJECTS: A total of 108 patients (72 +/- 10 years, 78 males) with atherosclerotic occlusive disease and critical limb ischaemia (pain at rest and/or trophic lesions) followed up for a median period of 1.6 years). (range: 8 days-5.5 years; 218 patient-years). MAIN OUTCOME MEASURES: Total mortality. RESULTS: Forty-five deaths (71% cardiovascular) occurred during the follow-up. Baseline fibrinogen was higher in those who died in the early follow-up period (first 6 months), as were white cell count and serum creatinine, while haematocrit was lower. Plasma fibrinogen values correlated positively with white cell count, and negatively with haematocrit; other cardiovascular prognostic factors did not differ. Only plasma fibrinogen predicted survival independently in multivariate age-corrected Cox regression analysis. Relative risk of death doubled for each standard deviation above the mean and increased with each tertile increase in fibrinogen. CONCLUSIONS: Fibrinogen predicted death in these elderly arteriopaths with critical limb ischaemia, particularly those who died in the first months following critical ischaemia. Inflammatory stimuli secondary to severely defective tissue oxygenation and possibly sepsis and necrosis, might have stimulated fibrinogen, an acute-phase reactant, thereby compromising organ perfusion through increased blood viscosity and/or promoting thrombosis.

Early diagnosis, place of diagnosis and persistent differences at 10 years in breast cancer survival. Hospitals and breast clinic cases prognosis.

In the Province of Florence (central Italy), the Center for Cancer Prevention (CSPO) runs a breast clinic for early diagnosis of breast cancer at which women can present as self-referrals or be referred by a general practitioner. About 55% of breast cancers incident in the area were diagnosed at CSPO. This paper evaluates the differences observed in 10-year observed and relative survival between hospitals and breast clinic cases. A population-based data set of 1182 invasive cases diagnosed in the years 1985 and 1986 (Tuscany Cancer Registry) was analyzed. Cox models were used to evaluate the effects of place of diagnosis on observed survival. In comparison to hospital cases, breast clinic cases showed a significantly higher frequency of localized cancer (55% vs 37%) and a better relative survival, persistent at 10 years of follow-up (69% vs 58%). The better survival of breast clinic cases persisted after age adjustment (hospitals cases; RR = 0.71, 95% CI: 0.60-0.84) and after age + diffusion of disease adjustment (RR = 0.79, 95% CI: 0.66-0.93). For regionally diffused cancers, breast clinic cases showed a 10-year survival significantly better than hospital cases. In conclusion, even if some bias (i.e. lead-time and length bias) could affect the comparison, breast clinic cases showed a better survival persistent until 10 years after diagnosis. An earlier stage distribution explained, at least partly, the different prognosis.

Linkage of AIDS and cancer registries in Italy.

We report the first results of a comparison between the Italian Registry on AIDS (RAIDS) and 13 population-based cancer registries (about 8 million population in 1991) with respect to the notification of Kaposi's sarcoma and non-Hodgkin's lymphoma. Routine indicators of data quality and completeness have been found in both types of registry, consistent with the best international standards. A linkage process was carried out on about 339,000 cancer notifications and 3,134 AIDS notifications and was herein restricted to individuals under the age of 50. Out of 243 Kaposi's sarcomas at either type of registry, 90 (37%) were reported as such by both; 68% of individuals with Kaposi's sarcoma at cancer registries could be identified at the AIDS registry, including AIDS-defining illnesses other than Kaposi's sarcoma; 62% of individuals with Kaposi's sarcoma at RAIDS could be found at cancer registries. Of 2,104 non-Hodgkin's lymphomas at either type of registry, 55 were reported as such by both; 65% of individuals reported as having non-Hodgkin's lymphoma at the AIDS registry were found at cancer registries. Our present results indicate the scope for improving cancer assessment in individuals with HIV infection and AIDS and the potential of AIDS and cancer registries for such a purpose.

High suicide mortality soon after diagnosis among cancer patients in central Italy.

A high suicide mortality risk has been documented among a population-based cohort of 27 123 cancer patients resident in central Italy where the general suicide rate is low. Forty-one suicides were observed (SMR = 2.36) which were only 0.2% of all deaths. However, the highest risk (SMR = 27.7) during the first 6 months after diagnosis, represents a greater contrast with the general population than has been observed in other studies.

Risk of cancer other than Kaposi's sarcoma and non-Hodgkin's lymphoma in persons with AIDS in Italy. Cancer and AIDS Registry Linkage Study.

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.

Survival after AIDS diagnosis in Tuscany (Italy), 1985-1992.

The study evaluated the overall survival after AIDS diagnosis of 1,014 patients reported to the Italian AIDS Registry as resident in Tuscany, stratified by age, gender, year of diagnosis, HIV transmission category, initial AIDS-defining disease and CD4+ cells count. The study was a population-based survival analysis, carried out through Kaplan-Meier method (mean survival times-MST-, 1, 2 and 3-year observed survival) and Cox models (crude and adjusted relative risk-RR). The MST was 12.4 months for all cases, increasing from 4-7 months in 1985-1987 to 14 months in 1991-1992. The observed survival was 51.4% at the first year of follow-up, 28.4% at the second year and 14.5% at the third year. The multivariate analysis showed an independent prognostic effect of age, year of diagnosis, initial AIDS-defining disease and CD4+ cells count. The prognosis was worse in cases aged over 44 (reference: 25-29), diagnosed before 1988 (reference: 1991) and with wasting syndrome, toxoplasmosis, HIV encephalopathy or multiple diseases (reference: PCP alone); and better in cases with more than 100 CD4+ cells/mm3 (reference: < or = 50 cells/mm3). The differences in gender and among HIV transmission categories disappeared after age-adjustment. The study confirmed, in an European population-based series, the poor long-term AIDS prognosis and, once AIDS has became clinically manifest, the prognostic value of some clinical and demographic variables.

Changing trends in the incidence of non-Hodgkin's lymphoma in Europe. Biomed Study Group.

Non-Hodgkin's lymphoma (NHL) is not a uniform disease entity, and in order to investigate the reported changes in incidence we have set up a study in seven population-based cancer registries in Europe. The study is designed to look at changes in the incidence of total NHL and disease subgroups using standard definitions and methodology. The registries are based in Leeds, Dijon, Kuopio, Odense, Florence, Eindhoven, and Ragussa. The classification system we have used is based on the REAL classification and has utility for epidemiological studies. We have used it to convert data sets which have utilized both local cases and the ICD-O classification. In order to improve data reproducibility, CLL/LL, myeloma/MGUS, lymphoblastic disease, and Hodgkin's disease have been excluded because of the difficulty in defining incident cases accurately. The preliminary results of this study show that there is still an upward trend in incidence rate and that in Yorkshire this is 3% per annum in total NHL. The subgroups which are increasing are extranodal and nodal peripheral T-cell lymphoma. Similar increases in incidence have been reported for the other registries. We conclude that there is a continued upward trend in incidence of NHL, the causes of which are uncertain.

Colorectal cancer survival--population-based rates in the province of Florence.

This study aimed to evaluate survival in 2,339 colorectal cancer patients diagnosed in 1985-87 in the province of Florence, where the Tuscany Tumour Registry is active. The effect of sex, site (colon, rectum), sub-site, disease diffusion (localized, regional, distant, unspecified), year of diagnosis, place of residence (municipalities involved in the screening programme, Florence, others) and source of diagnosis (Center for the Study and Prevention of Cancer-CSPO, others) were evaluated. Five-year observed and relative survivals were 37.9 and 48.1% respectively. Five-year prognosis was worse in men, in older age groups, in advanced stages and in patients not diagnosed at the CSPO. No differences were shown in residents of municipalities involved in the screening programme. Relative 5-year survival in Florence was among the highest in Europe for cancers of both the colon and the rectum. Sex, age, disease diffusion and source of diagnosis showed an independent prognostic effect. The effect of screening was not evident, probably due to the low compliance during the period under study and to the use of a low sensitivity test.

[Use of mortality statistics for the study of the distribution of digestive system tumors: characteristics and quality of the data].

We present an evaluation of the accuracy of death certificates in Italy for patients with cancers of the digestive apparatus in Italy: oral cavity and pharynx, oesophagus, stomach, colon rectum, liver, bilious ducts, pancreas. The diagnosis reported on death certificates is compared to post mortem examinations, diagnoses histologically confirmed, clinical and cancer registry records. For oropharynx cancer mortality data available from official statistics are underreported when compared to cancer registry data. The oesophagus presents misclassification problems with gastric cancer. Mortality data of stomach cancer show a good agreement with incidence and mortality data from cancer registries. No major differences are revealed among the various sources for colorectal cancer mortality. On the contrary the separate analysis of colon and rectum evidentiates diagnostical difficulties in identifying the primary site of intestinal cancers. Cancers of liver, bilious ducts and pancreas have a low percentage of cases with histological confirm and a high frequency of death certificate only (DCO) due to diagnostical difficulties.

[Survival for digestive system tumors: Italian population-based data and international comparisons].

Survival for malignant tumour of the upper digestive tract, oesophagus, stomach and pancreas are analysed from the data of 5042 cases observed during the period 1976-1985 by the Italian cancer registries (CRs) of Varese, Latina, Ragusa and Florence. Three-year relative survival rates were 42% for patients with tumours of the upper digestive tract and 7% for those tumour of the oesophagus. Five-year relative survival for patients with stomach cancer was 20%. A worse prognosis was found for cases from the Latina and Ragusa CRs. One-year relative survival for patients with pancreatitic cancer was 17%. Younger age, histologic confirmation, period of diagnosis (for upper tract, stomach and pancreatitic cancers), and female gender (for tumours of the upper tract) resulted as positively associated to survival.

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.

Completeness of AIDS reporting and quality of AIDS death certification in Tuscany (Italy): a linkage study between surveillance system of cases and death certificates.

In Italy, the AIDS cases defined according to the CDC criteria are reported to the National AIDS Registry (RAIDS, compulsory surveillance system). The aim of the present study is to evaluate the completeness of AIDS cases reported and the quality of AIDS death certification in an Italian Region (Tuscany, about 3,500,000 inhabitants). The 737 AIDS cases reported to RAIDS as residents in Tuscany (1987-91) were cross-linked (key link: name and date of birth) with the data of the Mortality Registration system of the Region (RMR). For the residents in Tuscany decreased with a 279.1 death diagnosis (the code for AIDS deaths stated by the Italian Census Bureau) and not reported to RAIDS as AIDS cases, the clinical records were reviewed to check whether the diagnosis fitted the 1987-CDC diagnostic criteria. This study shows that there is a high completeness (97-98%) of the AIDS cases resident in Tuscany, reported to the RAIDS. The quality of RAIDS data is not as good with regard to life status assessment (23% of under-reporting of death). In Tuscany, the death certification for AIDS (code 279.1 of ICD IX) has a sensitivity of 88% and a specificity around 100% in comparison to RAIDS. About 50% of 'false negatives' in death certification are due to causes of death presumably unrelated to HIV infection. The evaluation of the quality of AIDS surveillance and mortality data is important in the assessment of the impact for AIDS epidemic in a target population.

Trends in cervical cancer incidence in the district of Florence.

The trend in cervical cancer incidence in the District of Florence from 1975 to 1989 was investigated. Tuscany Cancer Registry data were available since 1985. Incidence data from 1975 to 1985 were obtained through a retrospective survey of all the Departments of Pathology and Gynaecology in the district. Cytological screening for cervical cancer has been available in the district since 1973, and since 1980 active invitation of residents aged 25 to 59 years has been in use. A significant trend in decreasing incidence was evident for the overall population (P = 0.003) and for 40-49 (P = 0.028), 50-59 (P < 0.001) and 60-69 (P = 0.002) year age groups, whereas no significant trend was observed for the age group 30-39 years. An association between attendance to screening and reduced incidence was evident, in that a greater reduction was evident for those cohorts (ages 50-59 and 60-69) who had a higher compliance to screening 10-15 years before. If the decrease in cervical cancer incidence was spontaneous, a parallel decrease of CIN3, which is commonly assumed to be the precursor of invasive carcinoma, would be expected. On the contrary, the detection rate of CIN3 at first Pap test showed a significant increase in the study period. All these findings suggest that the observed reduction in cervical cancer incidence was mostly due to the effect of screening, and stress the need for optimising the coverage of the invited population.

Population-based breast cancer survival. Mammographic screening activities in central Italy.

BACKGROUND: The aim of this study was to evaluate the effect on 5-year survival of patients with invasive breast cancer relative to demographic and clinical variables (age, residence, and disease diffusion) and to early diagnostic procedures performed in the area. METHODS: The observed (Kaplan-Meier method) and relative 5-year survival in 1263 patients with invasive breast cancer in the Province of Florence, Italy, between 1985-1986 (source: Tuscany Cancer Registry) are presented. The results were compared with those of other European areas and of the Surveillance, Epidemiology, and End Results Program. The Cox model is used to evaluate the effects of age at diagnosis (5-year age groups), disease diffusion (localized, regional, distant, unspecified), residence (Municipality of Florence, screening area, other municipalities), and source of diagnosis (Center for the Study and Prevention of Cancer, hospitals) on observed survival. RESULTS: Observed 5-year survival was 68.4% (Kaplan-Meier method) and relative 5-year survival was 75.4%. Relative survival for patients younger than age 35 at diagnosis was high (82.3%); it decreased slowly from 80.5% in the group of patients 35-44 years of age, to 74.0% in those 65-74 years of age, and steeply decreased to 68.1% in those 75 years of age and older. Relative 5-year survival in Florence was lower only than that observed in Switzerland (Geneva) and in the USA (whites). Five-year prognosis was worse in women 70 years of age or older, in advanced stages, in residents of municipalities not involved in the screening program, and in cases diagnosed in hospitals. The gain in survival may be explained partially by lead-time effect and by length bias due to early diagnosis both in self-referred women and in screening-detected cases. In these cases, though, the better prognosis, although attenuated, persisted after adjustment by disease diffusion. CONCLUSIONS: The results suggest that the early diagnosis of breast cancer in self-referred women affects prognosis, at least concerning 5-year survival. Moreover, although lead-time effect and length bias cannot be excluded in this study, screening by personal invitation may reduce the disadvantage in the survival of patients with breast cancer often observed in rural areas.
