Circulating levels and breast cyst fluid concentrations of human chorionic gonadotropin, progesterone and testosterone in women with gross cystic breast disease.

Circulating levels and cyst fluid concentrations of human chorionic gonadotropin, progesterone and testosterone were measured in 30 premenopausal women with gross cystic breast disease. Specific radioimmunoassay procedures were used. Amounts of human chorionic gonadotropin exceeding 5.0 mIU/ml were found in cyst fluid of many patients, but not in serum. Progesterone and testosterone concentrations in breast cyst fluid were significantly higher than in serum (p less than 0.01 and p less than 0.001, respectively).

Plasma and cyst fluid levels of delta 5 and delta 4 steroid hormones in women with gross cystic breast disease.

delta 5 and delta 4 steroid levels were studied in the plasma and cyst fluid of women with gross cystic breast disease (GCBD). In luteal phase a significant increase in plasma levels (mean +/- SEM) of DHA (11.2 +/- 2.4 ng/ml), DHAS (1.45 +/- 0.6 micrograms/ml) and cortisol 277 +/- 15.7 ng/ml) was found; in follicular phase the mean levels were 4.09 +/- 0.47 ng/ml for DHA, 0.65 +/- 0.08 microgram/ml for DHAS and 190 +/- 46.3 micrograms/ml for cortisol. The DHA/DHAS and cortisol/androstenedione ratios were significantly higher in the plasma and lower in the cyst fluid of GCBD patients, than in the plasma of controls; the androstenedione/DHA ratio was higher in the cyst fluid than in the plasma of controls. The hormonal situation of the GCBD patients thus differed from that of the controls both in the plasma and cyst fluid, particularly as regards the delta 5 steroids.

Bromocriptine for treatment of benign breast disease. A double-blind clinical trial versus placebo.

Over the last few years bromocriptine has been used for treatment of mastodynia and benign breast disease, but with contradictory results. This double-blind clinical trial was performed to determine the efficacy of this prolactin inhibitor as compared with placebo. Subjective discomfort, clinical examination of the breast lesions, echomammography and breast thermography were evaluated before, during and after 3 months of treatment and in a further follow-up. Plasma levels of estradiol, progesterone and prolactin were measured over the same time. Significant reduction of mastodynia and significant improvement of the breast lesions were observed in the group given bromocriptine, though echomammography and breast thermography did not reveal any significant differences between the two groups. Plasma prolactin levels were significantly reduced by bromocriptine administration.

Mass screening for breast disease. Results, problems, and expectations.

The first 18 months' experience of the Breast Diagnostic Center of Jefferson Medical College have been reviewed. Almost 14,000 patients were screened for breast disease, using a combination of clinical examination. Xeroradiography, and thermography. In this group of 14,000 women, 106 cases of cancer were discovered, in incidence of almost 8 per 1000 women screened. Of these 106 cases of cancer, 45.3% were clinically occult or not recognized by clinical examination, and within this group at the time of mastectomy only a small percent had any evidence of axillary lymph node metastases. The combination of several technics of examination is proving to be more reliable for the early detection of breast cancer than any of the technics alone, and programs such as these may make a significant difference in the death rate from breast cancer.

Endocrine aspects of benign breast disease.

The purpose of this study was to determine the levels of dehydroepiandrosterone sulfate (DHAS) in the plasma of women with benign breast disease (BBD) and in normal subjects. Possible changes in DHAS plasma levels and in its adrenal secretion under adrenocorticotrophin hormone (ACTH) were also investigated in women with BBD before and after bromocriptine therapy. Our results demonstrate that plasma levels of DHAS in women with BBD overlap with those found in controls. Prolactin (PRL) suppression in women with BBD receiving bromocriptine treatment was associated with a significant (p less than 0.02) decrease of baseline DHAS plasma levels and of stimulated ACTH response curve (p less than 0.02). These data suggest a possible relationship between PRL and DHAS secretion in women with BBD.

Color Doppler sonography of the lateral thoracic (breast-feeding) arteries: a new approach to the diagnosis of breast disease?

OBJECTIVE: The main arteries to the breast are the lateral thoracic artery and to a lesser extent the internal thoracic artery. In this prospective open diagnostic study involving 94 women, we compared the intraindividual differences of Doppler indices in the lateral thoracic (breast-feeding) artery of breasts affected by cancer with those unaffected by disease. METHODS: Sixty-seven consecutive patients were recruited from an outpatient unit for breast surgery and 27 volunteers were studied who were known to be without any breast disease (controls). In each patient we attempted to obtain Doppler indices from the lateral thoracic artery of both breasts. The difference in Doppler indices in each individual was assessed and statistical analysis was performed to assess whether these differences were significantly altered in women with cancer compared to healthy women. RESULTS: Lateral thoracic arteries could be visualized in 88% of the study population. Significantly lower values for pulsatility and resistance indices and systolic/diastolic ratios were obtained in the lateral thoracic arteries of breasts affected by cancer as compared to the contralateral breasts (1.73 +/- 0.39 vs. 2.05 +/- 0.47, P = 0.003; 0.78 +/- 0.06 vs. 0.84 +/- 0.06, P < 0.0001; 4.71 +/- 1.24 vs. 6.75 +/- 3.38, P = 0.0008, respectively). Using the intraindividual difference of pulsatility index, resistance index and systolic/diastolic ratio to screen for malignancy, sensitivities for breast cancer of 78%, 85% and 83%, respectively, were achieved. Depending on the cut-off level, specificity reached 94%. CONCLUSION: The intraindividual difference in Doppler indices in women with breast cancer may be a useful test for the diagnosis of breast lesions.

Breast disease in young women. When is biopsy indicated?

The low incidence of breast cancer among women under the age of 25 years may not justify the routine excision biopsy of breast lumps in this age group. A policy of conservative management has been tested in 70 women between the ages of 17 and 25 years. Excision biopsy was eventually performed in 23 women - fewer than half of those with a palpable mass. No cancerous lesions were found; a high proportion of lumps removed were fibroadenomas. The accuracy of clinical diagnosis was high and, of 31 breast lumps diagnosed as benign mammary dysplasia, more than three-quarters resolved without surgical intervention. Indications for surgery are defined. Because breast cancer does occasionally occur in this age group, accurate clinical diagnosis and review are essential components of conservative management.

Fine-needle aspiration cytology in the management of breast disease.

The results of a series of fine needle aspiration biopsies of breast lumps were reviewed to evaluate the accuracy of this diagnostic method and its place in the clinical management of breast lesions. A high level of diagnostic accuracy was achieved. There were no false positive diagnoses of malignancy and fewer than 3% of diagnoses were falsely negative. Eighty per cent of carcinomas could be confidently diagnosed by means of cytological investigation. The patient with a benign cytological diagnosis can either be reassured, or her surgical management planned as a day case. For the patient with a cytological diagnosis of malignancy, discussion of the nature of her surgery and subsequent care is possible before operation. In selected cases of carcinoma, mastectomy can be performed without frozen-section confirmation. Diagnostic accuracy is dependent upon experience, especially in aspiration technique, and optimum results are obtained if the pathologist/cytologist also performs the procedure.

[Invasive methods in complex radiologic diagnosis of breast diseases].

The report deals with such present-day invasive procedures of breast examination as X-ray-controlled puncture, puncture using X-ray contrast, Cytoguide video-accessory unit controlled puncture biopsy, "pistol-needle" application, ultrasound aiming puncture, pneumocystography, ductography and preoperative interstitial marking of nonpalpable masses. If latest invasive procedures are used during complex examination of the breast, diagnostic accuracy can be raised to 95-97%.

[Endoscopic surgery for breast diseases: the present state of art and outlook for the future].

Endoscopic breast surgery (EBS) is still not in common use today, mainly because of the lack of intracavitary operative maneuvers in breast surgery. It has been shown, however, that in experienced hands, the therapeutic benefits of EBS include not only improved natural esthetic outcomes but also less morbidity with faster recovery. Endoscopic partial/total mastectomy, axillary dissection, and breast reconstruction can be performed through an axillary incision with an additional periareolar incision depending on the situation, as safe alternatives to conventional operative procedures for early breast cancer. Furthermore, EBS is particularly effective when performing axillary dissection and mobilizing tissue flaps for immediate reconstruction. Since EBS requires the creation of a dissecting working passage and space, which tends to increase operative invasiveness, operating time, and blood loss, in less experienced hands an initial period of learning curve adjustment appears to be mandatory. Safety in terms of adequate local control must be further evaluated and long-term results need to be followed up before EBS can be applied in more advanced-stage breast cancer. Instead of being regarded as a competing technology. EBS should be welcomed and accepted in combination with conventional methods to nurture and further improve the technical aspects of breast cancer surgery. EBS is expected to become an indispensable and integral part of breast surgery in the near future, especially in an era when informed consent is sought with broader patient choice and empowerment models.

[Evaluation of the role of mammography and echography in breast diseases in a controlled caseload].

Data concerning patients who underwent mammography and breast ultrasonography and then breast surgery were collected and analyzed with a computer archive system. In previous papers the authors reported both design and implementation of the computer archive and analyzed the results concerning uncontrolled collected data; in the present paper data concerning controlled cases are evaluated, distinguishing between symptomatic and asymptomatic cases. Asymptomatic patients represented 92% of the whole evaluated population. However only one third of the patients who underwent surgery for breast cancer was included in this group. Breast cancer was discovered in 65% of the patients who underwent diagnostic procedures and then surgery because of a palpable nodule. This percentage was lower (52%) in asymptomatic patients. Mammographic accuracy was about 90% in symptomatic patients and 81% in asymptomatic patients. Breast ultrasonography was performed as a subsequent step and always detected the lesion when palpable. Its sensitivity was 86% in asymptomatic patients. In patients who underwent surgery the false positive rate for cancer was higher with ultrasonography (59%) than with mammography (45%). Focal dysplasis were responsible for the majority of false positive diagnoses with both procedures. However, the false positive rate is low referring to the whole investigated population and is reshuffled by guided bioptic procedures. Ultrasonography was a useful tool when mammography had limitations: in fact ultrasonography detected a focal lesion in all patients with a surgically proven cancer and a previous negative mammography. The sets of data available from the continuous updating of the computer archive immediately clarified the differences between symptomatic and asymptomatic patients and stressed the diagnostic capabilities of the different procedures.
