An attempt to increase compliance to cervical cancer screening through general practitioners.

The authors report the results of a campaign aimed at increasing compliance to cervical cancer screening by promoting general practitioners' (GPs) cooperation. Different types of intervention were tested, namely mailing lists of non responders to the GP, visiting the GP at the office, or both. No active intervention was made in a sample of GPs who served as a control group. Overall 288 GPs assisting 75,853 women aged 25 to 59 were enrolled in the study. Compliance before and after the campaign was studied and the association between compliance and different variables such as age, residence and type of intervention was tested by univariate and multivariate analysis. The proportion of previous non responders who performed a Pap test after the campaign was 6.7%, the response being dependent on age (25-29 = 11.5%, 30-39 = 8.8%, 40-49 = 6.5%, 50-59 = 4.2%) and place of residence (urban = 7.2%, suburban = 5.9%, rural = 4.0%). Compliance was better in the case of the active campaign (list mailing = 8.3%, visit = 7.0%, list + visit = 7.2%) with respect to controls (2.9%) although no significant differences were detected between different types of active intervention. Compliance to cervical cancer screening may be increased by promoting GPs cooperation but the benefit is limited. Mailing lists of non responders was found the most cost effective policy in this study.

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.

Telethermography and breast cancer risk prediction.

The authors report on 4,624 noncancer women classified by telethermography (TH1-2 vs TH3) and followed for an average of 6.6 years (range, 2-12). Breast cancer occurring beyond the sixth month from TH were recorded according to a Cancer Registry, and the association between breast cancer incidence and thermographic class or patient age was evaluated. Univariate analysis showed a significant association of age and thermography with further cancer incidence, but multivariate analysis (Cox's model) confirmed a significant association only for age. Thermography (TH3) showed a nonsignificant odds ratio of 1.6 with respect to TH1-2 cases. Thus thermography did not show any practical role as a breast cancer risk indicator. Possible biases affecting previous reports suggesting the use of thermography as a breast cancer risk indicator are discussed.

"T" category and operable breast cancer prognosis.

The authors report on 4,034 consecutively operated breast cancer cases, evaluating the correlation between clinical T category and long term survival. Age and pathologic nodal status were also considered as independent prognostic factors. Univeriate and multivariate (Cox's) analysis confirmed N status as the most powerful single prognostic indicator and did not reveal any prognostic correlation with age. T category was a strong prognostic indicator, independently of N status, the 10 year overall survival of T1, T2 or T3-4 cases being 0.86, 0.76 and 0.73 in N- and 0.73, 0.56 and 0.35 in N+ subgroups respectively. T category should be carefully considered not only in deciding the extent of surgical excision but also in planning adjuvant postoperative treatment.

Sensitivity of the screening program for cervical cancer in the Florence District.

Cervical cancer screening has been ongoing in the Florence district since 1966. All invasive cervical cancers occurring from 1975 to 1985 in the district have been considered and their screening histories have been investigated to estimate screening sensitivity. In the years 1975-1984, 236,045 women were screened initially. In this population all interval cancers have been recorded to estimate first screening sensitivity values according to the length of the interval since the first Pap test: 0.90 at 1 year, 0.78 at 3 years, and 0.68 at 5 years. Sensitivity values for subsequent screenings were lower than those for the first screening (0.68 at 1 year, 0.43 at 3 years), probably due to a lower number of prevalent cancers and to a progressive selection of cancers which are difficult to detect. The high sensitivity values confirm our choice of a screening frequency of 3 years.

Chest X-ray survey in the follow-up of breast cancer patients.

The authors report on 182 cases of intrathoracic metastases (ITM = lung, pleura or mediastinum) observed as first single recurrences in the course of the follow-up of patients treated for primary breast cancer. ITM were detected on standard two-views chest X-ray (CXR) at regular follow-up visits and in absence of subjective symptoms (102 A cases) or in the interval between two consecutive planned controls because of the onset of subjective symptoms (80 S cases). The average disease-free interval since primary treatment was significantly shorter in A with respect to S cases (40.3 vs. 28.5 months, P less than 0.001) as a consequence of the early detection achieved by CXR survey. On the contrary, prognosis was not influenced by ITM early diagnosis as the 10-year survival since primary treatment did not differ significantly between A or S cases (12% vs. 10%, P = 0.68). Results were confirmed on multivariate (Cox's) analysis, adjusting for potential confounders such as age or nodal status. Periodic CXR survey looks a very questionable policy as it does not seem to have any favourable impact on prognosis. Its routine use in breast cancer patients should thus be carefully reconsidered.

Association of estrogen receptors with parenchymal pattern at mammography.

The authors report on a consecutive series of 1,003 breast cancer cases classified on the basis of Wolfe mammographic parenchymal patterns and estrogen receptor content. The association between these two variables was investigated to assess the reliability of parenchymal patterns in predicting the estrogen receptor status. No significant association was observed after adjustment for possible confounders such as age, menopausal status, and T category. Mammographic parenchymal patterns appear to have no role in predicting estrogen receptor status.

Cervical cancer screening in Tuscany: a survey of the actual state of cervical cancer prevention in the Local Sanitary Units of the Tuscan region.

Every Local Sanitary Unit (USL) of the Tuscan Region was contacted to define screening variables, such as adequacy of the staff involved in prevention, smear technique, data collection and evaluation, laboratory quality control, and modalities of invitations to screening. The reported data show that 21 of 40 USL, but only 9 of 28 USL outside the Florence province (where a common screening program is performed), are performing active invitations to screening. The most serious staff inadequacies concern data evaluation and personnel performing the test. Sixteen of 28 USL outside Florence suggest an annual rescreening, which causes overcrowding of services and a poor availability for the unscreened population. Moreover, the poor quality of data collection makes it impossible to evaluate the benefit offered by the screening programs in the 28 USL outside Florence. Cytologic quality control is often lacking, and the smear technique is inadequate in 10 of 28 USL outside Florence. The lack in the USL of epidemiologic competence and of cost/benefit considerations and the need for political decisions about cancer prevention programs are stressed.

Cytologic screening for cervical cancer in the Florence District.

During the years 1970-1978, 213,575 women living in the Florence District had at least one cytologic smear. The overall incidence ratios were: dysplasia 1.09 0/00, carcinoma "in situ" 1.25 0/00, invasive carcinoma 1.01 0/00. Age of the women attending the service, and incidence ratios according to age groups are examined. Incidence ratios in women who had previous negative smears are calculated; these values seem to fit well with a "false negative model". These results are compared with those reported by other authors, and indications for a new kind of program are suggested.

Relationship between clinical and electromyographic findings and exposure to solvents, in shoe and leather workers.

A very high prevalence of polyneuropathy was observed in shoe and leather workers from the area of Florence. In addition, normal workers showed abnormally low maximal nerve motor conduction velocity. A linear decrease of motor conduction velocity was observed as a function of age and of the length of exposure to solvents. The worker population showed a steeper decrease with age than controls. A higher prevalence of polyneuropathy was observed when the amount of glue used by each worker per day was higher, and when the air volume of the plant was smaller. The subjective symptoms most frequently associated with polyneuropathy were muscle spasms, leg weakness and pain, and arm paresthesiae. Cases of polyneuropathy were more frequent in the workers exposed to solvents and in the older age group. A solvent aetiology of the disease is suggested, and glue substitution and proper hygienic conditions are recommended.

A comparative double-blind trial of the new antidepressant caroxazone and amitriptyline.

On the grounds of pharmacological properties and preliminary clinical trials the efficacy of the new antidepressant caroxazone was compared to amitriptyline in the management of depression. Forty patients mostly suffering from a neurotic or anxious-neurotic depression were admitted to a double-blind trial. All patients completed the study. The Hamilton Rating Scale for Depression was used for the clinical assessment at the beginning, during and at the end of treatment. The trial lasted three weeks. A significant improvement was seen for both drugs after seven days on most symptom scores and on total symptom score. No significant differences were found either at seven days of at the end of treatment between the two drugs. There were no significant differences in the incidence and severity of side-effects. In conclusion, caroxazone appears as an effective and well tolerated drug in the treatment of depression.

[Duration of antidepressive treatment. Recurrences and their prevention].

The basic strategy for the pharmacological treatment of depression, with special regard to its continuance following the start of remission, is outlined. The problem of the prevention of recurrences of dysthymic symptomatology is discussed and emphasis laid on the importance of lithium about whose use a fair literature is already available. The results obtained to date demonstrate the undoubted advantages of lithium salts (particularly of carbonate) in the maintenance of good affective balance, above all in the case of those subjects in whom the frequency or gravity of dysthymia seriously handicaps working or social life.

Contribution of cytology, colposcopy, target biopsy and conization to the early diagnosis of precancerous and cancerous lesions of the cervix uteri.

The study is based on 334 cytologic suspect or positive women observed in the area of Florence. Cytologic diagnoses of dysplasia, carcinoma in situ (CIS), and invasive carcinoma are related to the histologic reports. To the same histologic reports are related the colposcopic aspects. Lastly, diagnoses made by target biopsy are compared with the final diagnoses made by cone biopsy. The 3 diagnostic methods and their diagnostic accuracy are then compared. As regards dysplasia, the diagnostic precision of cytology is 40.2% and for target biopsy in 76.9%. In the diagnosis of CIS, cytology shows a diagnostic accuracy (77.7%) that is a little lower than that of target biopsy (81.7%). In invasive carcinoma, cytology has a good diagnostic precision (88.2%), which becomes 100% if the diagnosis is made by target biopsy. The correlation between colposcopic aspects and histologic reports is not very reliable. We conclude that cytology is a valid test in an extensive mass screening, that colposcopy is essential to execute target biopsy, and that the latter is useful in defining dysplasia and invasive carcinoma diagnoses. On the contrary, in the case of CIS, target biopsy does not greatly increase cytology diagnostic precision.

Trends in the prevalence of cervical intraepithelial neoplasia grade 3 in the district of Florence, Italy.

AIMS AND BACKGROUND: The objective of this study was to investigate the detection rate of cervical intraepithelial neoplasia grade III (CIN 3) in previously unscreened women, in order to reveal trends over time in the prevalence of CIN 3 in the District of Florence, where a population-based screening for cervical cancer has been going on since 1973. STUDY DESIGN: We considered the women, recorded in the computerized archives of CSPO, who had had no pap test for at least 10 years. Trends of CIN 3 (histologically proven) were analyzed within age groups; the effect of age, cohort and period were considered by means of a Poisson regression model. RESULTS: A total of 648 cases of histologically proven CIN 3 were detected in the study period. The detection rates of CIN 3 increased steadly within age groups over birth cohort and calendar period simultaneously. The Poisson regression analysis showed that only the model with age + time trend was statistically significant. CONCLUSIONS: Although several biases should be taken into account, the analysis seemed to indicate a real increase in CIN 3 prevalence. An increase in frequency of precancerous lesions for cervical cancer in more recent birth cohorts supports the need to keep screening coverage and efficiency as high as possible.

A feasibility study of screening for endometrial carcinoma in postmenopausal women by ultrasonography.

BACKGROUND: Abnormal endometrial thickness assessed by ultrasonography has been reported as a reliable indicator for early asymptomatic endometrial carcinoma. STUDY DESIGN: We evaluated the feasibility and the performance of screening by ultrasonography in a consecutive series of postmenopausal volunteers. RESULTS: A total of 2,025 women were screened, and 117 (5.8%) showed abnormal endometrial thickness. Ninety-eight subjects consented to be assessed by outpatient endometrial biopsy, which was not possible in 32 for cervical stenosis. Three cancers were detected among 66 assessed subjects, 34 not-assessed subjects were controlled by repeat sonography (no change), and 17 were lost to follow-up. No other cancer was recorded by the local Cancer Registry among screened subjects. The prevalence/incidence ratio was 2.65:1, and the cost per screen-detected cancer was 18,571,000 Italian lire. CONCLUSIONS: Screening by endometrial sonography is feasible on a practical basis, but its efficacy needs to be proven by prospective controlled studies which would enroll large populations to ensure sufficient statistical power, considering the low incidence and the low lethality of the disease. Studies of screening for other carcinomas may be considered of higher priority.
