Fine needle aspiration cytology and breast cancer diagnosis.

The authors report on 315 histologically confirmed consecutive breast cancer (BC) cases undergoing fine needle aspiration cytology (FNAC). Inadequate smears were infrequent (7%), particularly when reaspiration of inadequate cases was employed (1-2%). FNAC suspected BC in 81% of the total or 88% of adequate smears. Univariate and multivariate (Cox's model) analyses showed no correlation between inadequacy or suspect/positive FNAC rate and patient age, T category or histologic type. Differences in the inadequacy and suspect/positive rate were recorded among 30 operators (surgeons, oncologists, radiologists) performing the sampling, but the average results were consistent with literature reports. FNAC was found to be a useful diagnostic tool for BC diagnosis, and proper training of the highest number of operators is recommended to allow the widest diffusion of this diagnostic technique.

[A cohort study of art glass workers in the Empoli area].

The investigation aimed at studying cause-specific mortality of art glass workers employed in 17 industrial facilities in Tuscany, Italy. A cohort of 3390 workers employed for at least 1 year was obtained from company payrolls. Follow-up was between the year each factory started operations, mostly in the mid-fifties, and the end of 1993. The cause specific expected mortality was computed relative to Tuscany rates, specified for gender, 5-year age groups and calendar year. Separate analyses were carried out for the job titles of makers, batch mixers and grinders. For males, 3180 individuals, the observed mortality for cancer causes was above the expected for the lung [standardized mortality ratio (SMR) 123, 10 observed (Obs)], larynx (SMR 166, 10 Obs), stomach (SMR 105, 30 Obs) and brain (SMR 150, 7 Obs). For non-cancer causes observed mortality was above expected for hypertensive diseases (SMR 178, 10 Obs) and diseases of the genitourinary system (SMR 169, 11 Obs). Increases for the above listed causes were shown also among makers. Mortality for larynx and lung cancer increased with time since first exposure and significantly increased SMRs were observed for 21 or more years since first exposure: this pattern was still present with smoking adjustment. The results showed consistently increased mortality for lung and larynx cancer in the overall cohort and among makers. Stomach cancer, brain cancer, hypertensive diseases and diseases of the genitourinary system were also increased in the overall cohort and among makers.

[Cohort study of mortality among leather tanners in the Lower Valdarno area].

BACKGROUND: Epidemiological studies of tanners have shown increased risk for a number of cancer sites, namely: lung, bladder, kidney and urinary organs as well as stomach, intestine, pancreas, nose and nasal cavities, together with leukemias and soft tissue sarcomas. OBJECTIVE: To study cause specific mortality of leather tanners in Tuscany (Valdarno Inferiore area). METHODS: The cohort included 4874 workers (4150 males and 724 females) employed in 92 tanneries operating in 1996 (Valdarno Inferiore Tanneries Census) which were also operating on 31-12-1970. Ascertainment of vital status was completed for all individuals on 31-12-1998 (end of follow-up), and the cause of death was known for all deceased subjects. Demographic and work history data were obtained from factory payrolls. Regional mortality rates were used for comparison to calculate SMR (Standardised Mortality Ratio) and 90% Confidence Intervals (CI). In addition to the overall cohort analysis, for men only separate analyses were completed for finishers, chrome tanners and vegetable tanners. RESULTS: The study showed an increased mortality from lung cancer among finishers, Standardised Mortality Ratio (SMR) 145, 19 observed (obs) (90% Confidence Intervals, 90% CI 95-212), from bladder cancer in the overall cohort (SMR 134, 9 obs, 90% CI 70-233) and among finishers (SMR 125, 2 obs, 90% CI 22-393) and from pancreatic cancer among finishers (SMR 120, 2 obs, 90% CI 21-379). Mortality from lymphoemopoietic cancer is above expected, and the increase is mainly due to myeloid leukaemia, both in males (SMR 208, 5 obs, 90% CI 82-437) and females (SMR 599, 2 obs, 90% CI 106-1887). No deaths from soft tissue sarcoma were observed. A new finding of the study was the increased mortality from cancer of the endocrine glands (SMR 566, 4 obs, 90% CI 194-1297), psychiatric disorders (SMR 195, 6 obs, 90% CI 85-385) and blood diseases (SMR 329, 4 obs, IC 90% 112-752). CONCLUSIONS: The observations of increased lung cancer mortality among finishers, of bladder cancer in the overall cohort and among finishers, as well as an increase in pancreatic cancer among the latter, confirm previous epidemiological findings among tanners. The increase in myeloid leukemia mortality for both males and females, and the absence of deaths from cancer of the connective tissue, which includes soft tissue sarcomas, are worthy of note. The results should be valued with caution, given the small number of cases and the novelty of some observations.
