In Rochester, New York, 606 women were treated with ionizing radiation for post-partum mastitis, mostly between 1940 and 1955. Two-thirds of all breasts were treated, the average dose per breast being 377 rads (at 2.5 cm breast depth). Mammographic examinations were performed on 265 of these women still residing in this vicinity. Two nonpalpable carcinomas (with no axillary node metastases) were found in the twelve breast lesions that have been biopsied. Some of the biopsies revealed premalignant changes. It is recommended that women in this high-risk category have close medical supervision, as well as periodic mammographic evaluation, and that the importance of periodic breast self-examinations should be emphasized.

Serum samples from patients with primary breast carcinoma, breast carcinoma with metastases, chronic mastitis and fibroadenoma, and healthy individuals, were treated with hydrochloric acid and urea and analysed by polyacrylamide disc gel cationic electrophoresis. The discrete and highly reproducible patterns received showed variations from individual to individual. The frequencies of the presence and of the color intensity of every protein band were compared and profound differences were found for several bands between the four groups of patients and the healthy controls studied. The results suggest that a correlation exists between the electrophoretic profiles of partially hydrolysed serum cationic proteins and occurrence of disease, possibly useful for the early diagnosis of preneoplastic states.

The discrepancy between serum CEA levels and CEA tissue expression in patients with breast cancer is well known. Whereas immunohistochemistry shows positive CEA expression in 70-90%, the serum CEA levels are often within the normal range. We performed immunoscintigraphy and SPECT with a Tc-99m labelled anti-CEA monoclonal antibody (MAb BW 431/26) in 46 women with suspected breast cancer or recurrence. The results of anti-CEA immunoscintigraphy, mammography, serum CEA levels and immunohistochemistry were evaluated according to the histology of the tumor. Histology verified breast cancer or recurrence (pT1 [n = 7], pT2 [n = 17], pT3 [n = 3], pT4 [n = 3]) in 30 out of 46 patients; benign breast disease such as fibrocystic disease, fibroadenoma, fatty necrosis or chronic mastitis was responsible for suspicious mammographic findings in 16 patients. Immuno-SPECT showed 25 true-positive, 5 false-negative, 11 true-negative and 5 false-positive findings (sensitivity 83%, specificity 69%). Anti-CEA immuno-SPECT of 2 patients with bone metastasis showed all lesions previously detected by bone scintigraphy to be CEA-expressing metastases. In contrast, serum CEA levels were slightly elevated in only 5 out of 30 patients with histologically verified breast cancer (sensitivity 17%). The results of immuno-histochemistry were surprising; tissue CEA expression could be demonstrated in only 5 patients with breast cancer. According to our experiences with this Tc-99m labelled anti-CEA MAb, immuno-SPECT is a suitable additional method for the diagnosis of breast cancer and especially of recurrence. Pre-operative serum CEA levels give no support for the differentiation between benign and malignant breast tumors.

Pathological data on 1000 breast lesions obtained from Jordanian females were analyzed and compared to data available from other countries or ethnic groups. Ductal carcinoma was the most frequently encountered lesion followed by fibrocystic disease (mammary dysplasia), fibroadenoma and mastitis. The mean age of Jordanian females with ductal carcinoma was 44.5 years, and many patients presented with advanced stage of the disease as evidenced by the high frequency (74.6%) of nodal metastases in the patients who had axillary lymphadenectomy. The frequencies of medullary and mucinous (colloid) carcinoma were not greatly different from those in other countries, but lobular carcinoma had a substantially low rate of occurrence. Many patients with lactation-associated lesions such as mastitis, galactocele and lactating adenomas were noted, which is attributed to the high fertility rate in Jordan.

Metastatic disease to the intramammary lymph nodes from breast cancer may be seen mammographically. In the four cases reviewed, the affected intramammary lymph nodes were enlarged (1 cm or greater in diameter), homogeneous, and well circumscribed. All lacked the lucent center or hilar notch characteristic of benign intramammary nodes. Differentiation of malignant from benign causes of intramammary lymph node enlargement, such as inflammation or hyperplasia, is impossible by mammography. Biopsy is recommended for all intramammary lymph nodes of 1 cm or greater that are not fat infiltrated unless the patient clearly has an associated dermatitis or mastitis. Metastatic disease to the intramammary lymph nodes may be the first clinical and/or mammographic sign of breast cancer and may significantly affect prognosis.

Eighty-five specimens of breast tissue were grouped and investigated by the technic of mixed cell agglutination reation (MCAR) for studying isoantigens A, B and H (O). MCAR was found to be strongly positive at the epithelium of acini in all the 25 subjects with benign lesions (10 fibroadenomas, 10 cystic mastitis and 5 gynecomastias). On the other hand, all the subjects with diagnosis of primary carcinomas in breast (45 subjects) and their metastases (15 subjects) were found to be uniformly negative for any agglutination reaction. In view of these findings, it seemed that the isoantigens in primary and metastatic malignancies of breast are always lost, while in the benign lesions isoantigens are always present. Although the exact mechanism is not understood, it seems that, in malignancies with a glandular differentiation, some differences exist when these are compared to malignancies with a squamous differentiation. The various possibilities are discussed in the light of previous studies.

A 59-year-old woman presented with an infiltration in the left breast and a large mass of enlarged lymph nodes on the left side of the neck. Radiological and histological examinations showed that the breast involvement was a mastitis carcinomatosa secondary to a carcinoma of the stomach. A review of the literature revealed ten earlier cases of metastases to the breast from a primary carcinoma of the stomach. The cases are discussed especially concerning the way of tumour spread.

One hundred of women with diseases of the mammary gland were examined. Breast cancer was found in 31 patients, 65 patients had various benign tumors, 4 women had chronic mastitis. Breast cancer was manifested by pronounced focal elevation of temperature over the tumor, temperature asymmetry of mammary glands, uneven boundaries of hyperthermia focus with "pathways" of hyperthermia running from the tumor to regional lymph nodes (in 75% of cases) even when no metastases are found histologically. Patients with alterations in the mammary glands referred to as precancerous, are thermographically characterized by focal hyperthermia with distinct boundaries. Nonproliferating forms of fibroadenoma, as a rule, do not manifest themselves by focal pictures without changes in the general background of the thermogram.

The gross and microscopic pathology of breast cancers in women irradiated for acute postpartum mastitis was compared to the breast cancers found in the sisters of the irradiated women. Fifty-one cancers in 50 irradiated women and 25 cancers in 24 nonirradiated women were examined. In considering the lesions in the two populations, the size, location, histologic type, histologic grade, inflammatory response, lymphatic and blood vascular invasion, nipple involvement, axillary lymph node metastases, and menopausal status at the time of diagnosis were statistically indistinguishable. The only parameter that was different in the two populations was the desmoplastic response to the malignant lesion (P = 0.04). The control population had more marked fibrosis within the cancers compared with the irradiated women. With the exception of stromal response, this study shows that breast cancer in irradiated women is similar in the parameters evaluated to breast cancer in a control population.

201Tl and 99Tcm-MIBI have been used to evaluate palpable breast masses. The aim of this study was to evaluate the potential of 99Tcm-tetrofosmin as a new tumour localizing agent in patients with palpable breast masses. Nineteen palpable breast masses were evaluated in 18 patients. Each patient received 740 MBq 99Tcm-tetrofosmin intravenously. Ten minutes after the injection, planar breast images in the anterior, right lateral and left lateral views were obtained with the patient in the supine position. Mammography and ultrasonography were performed in all patients. Biopsy or mastectomy with axillary dissection was performed in all patients. Thirteen of 14 primary breast tumours were detected (9 invasive ductal carcinomas, 3 invasive lobular carcinomas, 1 papillary carcinoma). One patient with mucinous carcinoma did not demonstrate 99Tcm-tetrofosmin accumulation. Four of five patients with histopathologically proven benign lesions did not demonstrate 99Tcm-tetrofosmin accumulation (2 fibrocystic diseases, 2 fibroadenomas). 99Tcm-tetrofosmin accumulation was seen in a patient with chronic mastitis. The sensitivity and specificity of 99Tcm-tetrofosmin for malignant breast lesions was 92 and 80% respectively. Four of seven (57%) axillary lymph node metastases showed 99Tcm-tetrofosmin uptake. In conclusion, 99Tcm-tetrofosmin shows real promise for use in evaluating patients with palpable breast masses.
