"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.

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.

Time interval since last test in a breast cancer screening programme: a case-control study in Italy.

STUDY OBJECTIVE: To evaluate a population based screening programme for breast cancer. DESIGN: This was a case-control study of women dying of breast cancer between 1977 and 1987 who had been invited to take part in a screening programme. SETTING: Community based study of women aged between 40 and 70 years (total population about 35,000 at 1981 census), living in 23 small towns near Florence, Italy. PARTICIPANTS: 103 cases were identified from death certification, and 515 living controls (five per case) selected for year of birth and town of residence. MEASUREMENTS AND MAIN RESULTS: Screening history was obtained from computer archive. Sociodemographic information was obtained from town registry offices and directly from relatives of the deceased and from the controls by postal questionnaire, and if necessary telephone or personal interview. Analysis was carried out on two age groups--40-49 years and 50+ years at diagnosis--and considered the number of screening tests and the time interval since the last test, separately and together. In the older age group, women with at least one screening test in the previous 2 1/2 years showed a 50% reduction in risk (odds ratio 0.49, 95% confidence interval [CI] 0.25-0.95). If they had also had another previous negative screen the risk was reduced to one third (odds ratio 0.35, 95% CI 0.14-0.85). There was a significant trend of decreasing risk with increasing number of screens in older women. No clear evidence of a similar protective effect was shown for women in the 40-49 year age group. CONCLUSIONS: A significant protective effect of the screening programme is evident in older women but not in younger ones. The data do not allow an assessment of optimal screening interval because of the small number of previously screened cases.

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.

Nonpalpable breast lesions: stereotaxic fine-needle aspiration cytology.

The authors reviewed the accuracy of stereotaxic fine-needle aspiration cytology in prediction of the presence of cancer. Seventy-four nonpalpable breast cancers and 144 benign lesions were studied. The rate of obtaining an inadequate sample was 8.1% for cancers and 20.8% for benign lesions. None of the cytology reports were false-positive, whereas the accuracy of cytologic atypia in prediction of cancer was 72%. Sensitivity and specificity after 1 year of follow-up were 83.8% and 96.6%, respectively, with atypia reports being assumed positive. In patients strongly suspected of having cancer at mammography, the decision to perform biopsy must be independent of the cytologic report, as false-negative cytologic findings are expected. In patients with a low suspicion at mammography, abnormal cytologic findings were the determining factor for a request for biopsy of six cancers and of two benign lesions. Negative cytologic results contributed to the recommendation of follow-up of two lesions that turned out to be malignant. At the authors' institution, the benign-to-malignant biopsy ratio of nonpalpable lesions was greatly reduced after stereotaxic cytologic study became available; the rate of detection of subclinical cancer remained almost unaffected.

Selection criteria in colorectal cancer screening.

The authors report the results of a risk questionnaire (RQ) used in a population-based screening program for colorectal cancer. The positive predictive value (PPV) for cancer or adenoma was evaluated for the Hemoccult test (HO) and for all RQ items (symptoms, personal and familial risk) in 8,114 cases, by univariate and multivariate analysis. A significant correlation with the presence of cancer or adenoma was observed for HO-positive tests, whereas a significant correlation was absent for most RQ variables. The use of an RQ in screening practice is disregarded since it does not improve the rate of cancer detection. Moreover, the increase in the detection rate of HO-negative adenomas does not justify the high rate (0.18) of screening responders selected for endoscopic diagnostic workup, a figure which influences negatively the overall compliance to screening.

The double contrast barium enema in the identification of proximal colonic adenomas and carcinomas beyond the limits of fiberoptic sigmoidoscopy.

Eight hundred and twenty patients were examined by fiberoptic sigmoidoscopy (SIG) and double contrast barium enema (DCBE) to detect colonic cancers or adenomas. Cancer or adenoma in the bowel tract proximal to the upper limit of SIG insertion was detected in 4 patients and in 12 on DCBE. The DCBE detection rate of proximal colonic lesions varied according to the hemoccult (HO) outcome. This was 1.16% for cancer and 2.03% for adenoma in HO+ patients and null for cancer and 1.23% for adenoma in HO- patients. The detection rate of proximal adenomas was higher in patients who presented adenomas on endoscopy in the distal bowel (SIG+), 2.46% as compared to 0.48% in SIG- patients, independent of the HO reports. Routine DCBE is practically useless in HO-SIG- patients and questionable in HO-SIG+ patients since improvement of the detection rate is null for cancer and moderate for adenoma. It is recommended for HO+ patients because it increases the colonic cancer detection rate (10.5% in this study).

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.

The role of galactography in the detection of breast cancer.

The authors report on a series of 529 consecutive patients examined on physical examination, mammography, nipple discharge cytology and galactography. The criterion for galactography was essentially bloody nipple discharge (73% of cases). Serous nipple discharge was not considered worthy of routine galactography since it is associated with an extremely low incidence of breast cancer. Surgical excision and histologic examination of the discharging duct was performed in 200 cases. Eighteen cases of breast cancer were detected (10 infiltrating, 8 intraductal) of which 9, 6, 7 or 7 were suspected on physical examination, mammography, cytology or galactography, respectively. All combined tests suspected 13 of 18 breast cancers; 3 intraductal breast cancers were biopsied because of evidence of multiple papillomas on galactography, and 2 infiltrating breast cancers were operated because of persistent bloody nipple discharge in the absence of any other sign. No breast cancer was suspected on galactography alone. Galactography is indicated in the presence of bloody nipple discharge, and a biopsy should be performed when breast cancer or multiple papillomas are suspected. The diagnosis and excision of a single papilloma (breast cancer was never misdiagnosed as a single papilloma on galactography) is not worthwhile since a single papilloma is a benign lesion, and the benefit of its excision is still unclear.

Preoperative staging of primary breast cancer. A multicentric study.

This article reports on a consecutive series of 3627 breast cancer (BC) patients undergoing preoperative staging by chest x-ray (CXR), bone x-ray (BXR) or bone scintigraphy (BS), and liver ecography (LE) or liver scintigraphy (LS). The detection rate (DR) of preclinical asymptomatic distant metastases depended on the T and N category (TNM classification system), and was very low (CXR: 0.30%, BXR: 0.64%, BS: 0.90%, LE: 0.24%, LS: 0.23%). The sensitivity, determined after a 6-month follow-up, was below 0.50% for all tests. The highest value (0.48%) was recorded for BS, which also had the lowest specificity (0.95%). The entire preoperative staging policy using the studied tests seems questionable due to poor sensitivity and an extremely low DR of distant metastases.

Prognostic significance of estrogen receptor determination in primary breast cancer.

The authors report on 767 consecutive primary Stage I-II breast cancer cases followed-up from 3 to 8 years. The estrogen receptor (ER) content was determined in all cases and did not influence the treatment choice. A correlation was attempted between ER and menstrual or pathological nodal status (N) or the 5-year disease-free survival (DFS). ER was correlated with menopausal status ER+ cases being more frequent in postmenopausal patients, whereas no correlation was observed between ER and nodal status. In absence of nodal involvement (N-) the prognosis was not influenced by the ER status. A significantly better DFS was evident for ER+ respect to ER- patients in the N+ series but such a correlation is questionable as the adjuvant treatment (hormone or chemotherapy) given to such patients may have influenced the DFS according to the ER status. According to the present study, ER determination should not be used as a discriminant in the performance of adjuvant postoperative treatment based on a prognostic judgment.

Breast cancer diagnosis under the age of forty years.

The authors report on a multicentric consecutive series of 382 cases of primary breast cancer detected before the age of 40 years. Physical examination (PE) was always performed, whereas other diagnostic tests were performed in selected cases, namely mammography (M) in 334, fine needle aspiration cytology (CYT) in 188 and thermography (TH) in 123 cases. Single tests showed a high rate of false-negative/benign cases (PE, 0.23; M, 0.26; CYT, 0.37 and TH, 0.50), especially when the T1 subgroup was considered (PE, 0.34; M, 0.38; CYT, 0.42 and TH, 0.78). The poor results recorded for TH make its current diagnostic use highly questionable. The policy of extensive biopsy of all "dubious" benign lesions on PE allowed for the detection of 41 of 382 cancers and reduced the PE false-negative/benign rate to 0.12 for the total or 0.15 for T1 cancers, although about 80 unnecessary biopsies for each cancer detected were performed in this way. The association of PE to one or more tests resulted in even lower false-negative rates (0.06 for the total, 0.10 for T1 cancers). The authors criticize the aggressive policy of extensive biopsy recommendation based only on a dubious report on PE alone and stress the opportunity of the routine association of M and CYT to PE, since this combination seems to achieve a higher breast cancer detection rate even in this age group.

Chest x-ray survey in breast cancer follow-up--a contrary view.

The authors report on 83 cases of intrathoracic metastases (ITM) observed as isolated first recurrences in a ten-year experience of periodic chest x-ray (CXR) survey of primary breast cancer. In 44 of 83 cases ITM were detected on CXR in absence of subjective symptoms or clinical signs (A) whereas 39 ITM cases were detected as subjectively (S) symptomatic in the interval between two planned CXR controls. Diagnosis was anticipated by CXR survey as the disease-free interval was significantly shorter (30 vs. 43 months, p less than 0.04) for A respect to S cases. Nevertheless such a diagnostic anticipation had no prognostic impact as the ten year survival from primary treatment did not differ (0.12 vs. 0.16, p = 0.6) between A and S cases. Multivariate analysis confirmed that no impact on survival from primary treatment is expected whether ITM are detected in an earlier (asymptomatic, preclinical) or in a more advanced (subjectively symptomatic) phase. CXR survey after primary treatment of breast cancer seems thus a very questionable policy.

Nonpalpable lesions detected with mammography: review of 512 consecutive cases.

The authors reviewed 512 consecutive cases in which biopsies were performed on nonpalpable lesions of the breast detected with mammography from 1970 to 1985. The positive predictive value (PPV) of different radiologic patterns was determined. Biopsy is advised in the presence of patterns such as parenchymal distortion, opacities with undefined borders, strongly suspect microcalcifications (rodlike or branching morphologic features, high spatial density), and stellate opacities, which yielded higher PPVs (0.11, 0.35, 0.56, and 0.75, respectively). The average detection rate of preclinical cancer was 0.7 per 1,000; wide variations were recorded during different periods in the study (0.2 per 1,000 and 1.3 per 1,000 in the first 4 years and the last 4 years of the study, respectively), for the different age groups considered (0.6 per 1,000 and 1.7 per 1,000 for the 30-39-year and over-59-year age groups, respectively), and for different reporting radiologists (0.5-1.9 per 1,000). The ratio of benign to malignant biopsy findings was 2.4:1 for the whole series, with wide variations encountered relative to the variables mentioned above.

Diagnostic and prognostic role of infrared thermography.

A series of 469 breast cancer studied by physical examination (PE), mammography (M) and infrared thermography (TH) is discussed. Follow-up was performed up to 5 years later. The poor diagnostic role of TH is proven for the low sensitivity in the total series (0.47) and, particularly, in T1 cancers (0.26). TH does not increase significantly the cumulative sensitivity (0.98 vs. 0.97 in the total series). Its limited advantage is offset by the great number of useless biopsies due to TH false positive. A correlation between TH pattern and prognosis is evident only when TH is considered independently from other reliable prognostic indicators such as the T or N categories. If survival curves are stratified by T or N or if a multivariate analysis based on TH, T and N variables is performed, all correlations between TH pattern and prognosis disappear; for this reason the use of TH as a prognostic indicator in the clinical practice is disregarded.
