Thermal evaluation of breast disease using local cooling.

A simple, inexpensive local cooling system for thermal evaluation of breast disease is described. Skin temperature measured during a 10-minute cooling process averaged 1.2degrees C higher over 31 proved cancers and 0.6degrees C lower over 18 benign masses. Forty-nine masses averaged 1.7 cm in diameter and were 1.5 cm deep; 23 of 31 malignancies (74%), 16 of 18 benign growths (88%), and 46 of 52 "normals" (88%) would have been correctly diagnosed, while results for 10 of 22 women (45%) with asymmetrical diffuse non-malignant disease would have been falsely classified positive.

Breast disease programs in obstetrics and gynecology: a plea for training in mammography.

Obstetrics and gynecology residency programs have started to integrate structured breast disease teaching programs into the curricula. I suggest that mammography training should be the cornerstone of programs on the diagnosis of breast diseases. The implementation of such a program into a teaching department is described in an attempt to facilitate similar efforts elsewhere.

Clinicians and pathologists in the management of breast disease. An evolving relationship.

The breast is host to a spectrum of benign and malignant diseases. Medical advances during the last few decades have changed and refined the diagnosis of breast diseases considerably, and their treatment has become increasingly sophisticated. These changes have changed the relationship between pathologists and clinicians: Close collaboration has become even more essential for optimal patient care.

Sonomammography in benign breast disease.

An assessment is made of direct-contact B-scan sonomammography in 480 patients with clinically benign breast disease, of whom 121 underwent biopsy. In eight patients, ultrasound was normal when histology showed diffuse benign disease, and in four patients, ultrasound gave a benign result when histology showed malignancy. In 25 patients, attenuating shadow led to biopsy for a false positive diagnosis of carcinoma. Ultrasound can be used to avert unnecessary biopsy either by excluding a focal mass or by revealing clinically unsuspected malignancy when X-ray mammography shows moderate or marked density in patients complaining of a breast lump or nodularity.

[Follow-up study of benign breast diseases].

Follow-up study after surgery of the benign breast disease revealed that rates of the recurrence were 50%, 6%, 4%, 3.5% in those who had phyllodes tumor, duct ectasia, intraductal papillary lesion, and multiple fibroadenoma, respectively. Incidences of the subsequent breast cancer development were 14.3% after ADH, 11.7% after ALH, 1.5% after PDWA, respectively. However no difference was found statistically among those diseases(X2 = 2.89). The longest interval between time of the first surgery and time of detection of subsequently developing cancer was 68 months. Accordingly, checks at three times of postoperative third, fifth and eighth year were required for early detection of such subsequent breast cancer, using image diagnostic methods.

Oral contraceptives and reduced risk of benign breast diseases.

In 1970 a questionnaire on oral-contraceptive use was mailed to 97,254 married women 25 to 49 years of age in Greater Boston. Sixty-nine per cent responded. During the subsequent 30 months, 1072 of the women were hospitalized for breast diseases. Hospitalization rates for fibrocystic disease were similar for non-users of oral contraceptives and users of one to 12 months' duration. However, users for 13 months to 24 months and 25 or more months had rates only 70 and 35 per cent, respectively, of those of non-users. Detailed analysis of these results, and their similarity to findings in previous studies, suggest that the association is causal--use of oral contraceptives appears to lower risk of fibrocystic breast disease. A similar association was seen for fibroadenoma. Rates of breast cancer were lower for users than for non-users, but this finding was neither related to duration of use nor statistically significant.

Vascularity of proliferative breast disease and carcinoma in situ correlates with histological features.

The level of vascularity within an invasive breast carcinoma is a predictor of metastatic potential and survival. However, little is known about the vascular potential and prognostic value of angiogenesis in preinvasive breast pathology. Women with proliferative breast disease or carcinoma in situ are at increased risk of developing invasive breast cancer. This relative risk increases in correlation with defined histopathological features. We asked whether these early proliferative lesions and carcinoma in situ were capable of inducing a vascular supply. Vascularity in preinvasive archival paraffin-embedded breast tissue from 90 patients was quantified by immunohistochemical identification of vessels using anti-von Willebrand factor. Vascular scores were analyzed with respect to histopathological diagnosis, age at diagnosis, and presence of coincident invasive disease. These data indicate that: (a) the vascularity of histopathologically normal epithelium is greater in breasts containing invasive disease than in breasts lacking invasive disease; (b) simple proliferative breast disease induces a vascular supply greater than that of normal breast epithelium; and (c) vascularity increases in proportion to epithelial lesion progression and relative risk of invasion. These studies indicate that the vascularity of preinvasive breast pathology may be a clinically useful predictor of invasive breast cancer.

Biallelic expression of the IGF2 gene in human breast disease.

We examined the imprinting status of the insulin-like growth factor II gene (IGF2) in a series of 20 human breast disease samples to determine if disrupted imprinting (as evidenced by biallelic expression), was a demonstrable mechanism of altered gene expression. These samples included benign (n = 7) and malignant breast lesions (n = 13). Biallelic expression of IGF2 was detectable in 67% of benign and 60% of malignant informative breast lesions. Three informative reduction mastectomies displayed normal IGF2 imprinting. The presence of this alteration in human breast tissue is a novel finding, and may contribute to tumorigenesis, possibly by favouring an enhanced proliferative milieu, during which additional mutations could occur.

Exogenous hormone use and fibrocystic breast disease by histopathologic component.

In a hospital-based case-control study of 590 women with biopsy-proven fibrocystic breast disease and 1,018 control women with other surgical conditions, no linear relationship was evident between the use of oral contraceptives or of estrogen replacement therapy and the degree of epithelial atypia of the fibrocystic lesions. Case-control and intracase comparisons suggested that oral contraceptive use might be associated with an increased occurrence of sclerosing adenosis among the premenopausal women and of gross cysts among the postmenopausal women. Estrogen replacement therapy, which was positively associated with fibrocystic breast disease as a whole among the post-menopausal women, was most frequently used among the cases whose biopsy specimens exhibited gross cysts, papillomatosis or papillary hyperplasia.

[Benign breast diseases: hormonal studies in 125 cases (author's transl)].

The results of exploration of the corpus luteum in 125 patients with benign breast disease are analysed. In 109 patients, plasma oestradiol and progesterone were measured at various times during the hyperthermic phase of the menstrual cycle. The results obtained were compared with those obtained in normal women explored during the same phase of the cycle. The average daily values for plasma progesterone obtained in this group of 109 patients was significantly lower than that found in the normal women, whilst there was no change in oestradiol levels. In addition, 16 patients were studied daily throughout the period of hyperthermia. In 8 cases, there the hyperoestrogenism, with or without progesterone insifficiency of the corpus luteum. In all, secretory imbalance of the corpus luteum with a tendency to relative or absolute hyperoestrogenism was a constant finding in women with benign breast disease.

Benign breast diseases associated with cyclosporine therapy in renal transplant recipients.

PURPOSE: Our aim was to correlate the radiologic characteristics of cyclosporine-induced benign breast diseases with clinical and pathologic findings. MATERIALS AND METHODS: The clinical, mammographic, and ultrasonographic records of 33 female renal transplant recipients who received cyclosporine were retrospectively reviewed. Eleven patients had 46 breast masses on ultrasonography. We performed core needle biopsies on 20 masses and reviewed the pathologic findings. RESULTS: Among 33 female renal transplant recipients, 11 (33%) had 46 benign breast lesions detected on ultrasonography. We performed core needle biopsies on 20 of the 46 masses. On pathologic examination, 12 were fibroadenomas, 6 showed fibrocystic changes, and 2 revealed dense fibrosis. Regardless of the final pathologic diagnosis, more than half of the lesions revealed severe lymphatic and venular swellings. Among 11 patients with breast lesions on ultrasonography, 10/11 (91%) showed multiplicity, and 7/11 (64%) bilaterality. Mammographically, patients with breast lesions revealed heterogeneous or extremely dense breast patterns, and 8 of 11 patients, circumscribed masses. Twenty-two patients without breast lesions showed scattered fibroglandular densities (n = 7), or heterogeneously dense (n = 11) or extremely dense (n = 4) breast patterns, and 3 of 22 patients showed vague or asymmetric densities that needed further evaluation. CONCLUSION: The development of new breast lesions in patients after renal transplantation should suggest a diagnosis of cyclosporine-induced benign breast disease including fibroadenoma, fibrocystic changes, and dense fibrosis.

Consultations for breast disease in general practice and hospital referral patterns.

As part of the evaluation of a health education campaign about breast disease, consultations for breast problems were monitored in five general practices over an 18-month period in Edinburgh. No increase was found as a result of the campaign, nor was there any increase in the number of biopsies performed. On average, each GP saw 13 women with breast problems each year, a rate of 1.6 per cent; 29 per cent were referred to hospital, regardless of their age. The most common presenting symptom was pain (47 per cent), with 35 per cent complaining of a lump. The reasons for hospital referral are discussed. It is suggested that GPs may refer too many young women to a specialist clinic, although this may be inevitable.

Endocrinology of benign breast disease in relation to the severity of radiological dysplasia.

A link between benign breast disease and hormonal imbalance has not been conclusively determined. In women suffering from severe radiological dysplasia, it was found to be correlated with slightly raised serum hormone binding globulin (SHBG) binding capacity. SHBG is an oestrogen-sensitive protein, which may be a marker of enhanced oestrogen bioactivity. Such abnormality was not, however, detected by the measurement of peripheral steroid hormones.

Association between polycystic ovary and fibrocystic breast disease.

OBJECTIVE: The aim of this study was to assess whether or not there was an association between a polycystic ovary (PCO) and fibrocystic breast disease based on ultrasound findings, both pelvic and mammographic. DESIGN: Prospective case-control study. POPULATION: Women aged between 18 and 30 years not using oral contraceptives attending the outpatient ultrasound clinic from January 1996 to December 1998. MAIN OUTCOME: Confirm the association between PCO and fibrocystic breast disease. RESULTS: According to the ultrasound findings, women were allocated to three groups: 351 out of 456 showed normal-appearing ovaries (group A), 93 had polycystic-appearing ovaries/PCO (group B) and 12 had PCO syndrome (group C). In group A, 24 (6.83%) women showed breast pathology. In group B, there was an association between PCO and breast pathology in 53 (56.98%) women, while in group C it was noted in 11 out of 12 (91%). CONCLUSION: This study showed a significant association between PCO and benign pathology. This should encourage the performance of a screening breast sonography on women with PCO.
