Serum leucine aminopeptidase estimation: a sensitive prognostic indicator of invasiveness in breast carcinoma.
Serum Leucine Aminopeptidase (LAP) was studied in 25 patients of breast tumors, and compared with 50 age matched controls. Clinical staging was done in 13 cases of breast carcinoma. Serum LAP was increased but not significantly in stage I (P less than 0.1), while in stage II & III, significant increase was observed (P less than 0.05), but a sharp peak was noted in stage IV with metastasis in liver (P less than 0.001). Serum LAP values were correlated with histological sub-types of breast carcinoma. Highest serum LAP values were observed in filtrating duct carcinoma with productive fibrosis (P less than 0.01), followed by medullary carcinoma and the enzyme values were slightly decreased in intraductal carcinomas.

[Functional morphology of breast APUD cells in dysplasia and neoplastic processes].
Histochemical and immunohistochemical methods were used to examine 29 malignant tumors (18 lobular and 11 invasive carcinomas) and 34 fibroadenomas of the mammary gland (MG). APUD cells containing serotonin, melatonin, and beta-endorphine were shown to be present in the duct epithelium of the normal MG and its pericanalicular fibroadenoma. APUD cells were detected in 21 of the 29 malignant tumours of MG. Hormonal differences of APUD cells were found in poorly and well differentiated carcinomas: the former contained serotonin, melatonin, and beta-endorphine (inhibitors of proliferation), the latter--insulin and adrenocorticotropic hormone (stimulators of cell division). Such differences in the endocrine function of MG malignant tumors are likely to be significant in the clinical course and determination of prognosis for carcinomas of various differentiation.

[Pathology of premalignant and malignant diseases of the female breast].
There are three frequent, basic diagnoses of breast lesions: fibroadenomas, fibrocystic diseases and carcinomas. The atypical fibroadenoma, the phyllodes tumour, the atypical ductal and/or lobular hyperplasia and the atypical papilloma are important because they may be a premalignant condition. For therapy it is important to know that the non-invasive carcinomas are often plurifocal, multicentric and bilateral. Women with manifest invasive breast cancer have a very high risk of contralateral cancer, but generally the cancer on the opposite side is microfocal.

[MR characterization of breast pathology using inversion recovery sequence].
As yet, a valid tissue characterization of human breast diseases has not been possible with conventional MR techniques. On the basis of the experimental thesis according to which fibroadenomas and carcinomas have a slight, though significant, difference in T1 relaxation times, we employed specific inversion recovery sequences at the T null of the breast glandular and adipose tissues, to enhance the differences in the signal intensities of the various pathologies. We examined 16 (6 cystic dysplasias, 5 fibroadenomas, 3 carcinomas, and 1 phylloid fibroadenoma) selected patients with the above-mentioned sequences in addition to the routine T1- and T2-weighted spin echo sequences. The following conclusions were reached by evaluating the characteristic signal intensities: MR spin echo sequences allow solid lesions to be distinguished from cystic ones; MR inversion recovery sequences allow fibroadenomas to be distinguished from carcinomas with 88% accuracy.

[Quantitative characterization of nuclear polymorphism of the epithelial cells in fibroadenomatosis and cancer of the breast].
A method for quantitative analysis of epithelial cell nuclear polymorphism was suggested, viz. identification of general statistical population using Petunin's criterion. This criterion was employed to assess heterogeneity of visible surface of interphase epithelial cell nuclei and to assay nuclear DNA level in fibroadenomatous hyperplasia and cancer of the breast. Heterogeneity index (h), alongside with other parameters, appeared useful for quantitative assessment of the disease: heterogeneity index values ranging 0.1-0.4 point to pronounced heterogeneity of epithelial cell nucleus surface and DNA level, and are suggestive of malignant transformation of tissue, whereas benign proliferation of the epithelium is usually characterized by 0.4 less than h less than or equal to 0.9.

[Detection of steroid hormone receptors in patients with mastopathies and fibroadenomas].
Estradiol and progesterone receptors have been determined in 74 women with mastopathy and 33 women with fibroadenomas in the period from 1986-1988. Mastopathy was classified according to Prechtel (stage I-III). A negative steroid-hormon-receptorstatus (less than 10 fmol/mg protein) was predominant in the group with Prechtel I and II. In our study the progesterone receptor was detectable more frequently than the estradiol receptor in patients with mastopathy or fibroadenomas.

[Investigation on calcifications in the breast].
This article reported the result of analysis of 96 cases with heaps of calcifications in the breast all verified by operation. The calcifications, according to the appearances on X-ray film were classified into 4 patterns: club-shaped, fine sandy, fragmented stonelike and coalescent. A comprehensive analysis was made in regard to spatial distribution and amount of calcification and the presence of a mass. The results indicated that club-shaped calcification is highly suggestive of malignancy regardless of the amount of calcification and the presence or absence of a mass. Simple fine sandy calcification in the absence of a mass can not differentiate benign from malignancy because of wide range of overlapping, whereas simple fragmented stone and coalescent types, according to the authors opinion denote benign.

[Breast repair using a silicone gel-filled prosthesis. Report of 21 cases].
From March 1985 to May 1988, a total of 32 breast repairs in 21 patients following mastectomy were performed in our hospital. The operative procedures included: immediate prosthesis insertion following subcutaneous mastectomy in 16 patients; subsequent prosthesis implantation following simple mastectomy in 4 patients; a transfer of latissimus dorsi skin-muscle flap with submuscular placement of prosthesis subsequent to the radical mastectomy in 1 patient. The chief indications for mastectomy are: multiple fibroadenomas, giant fibroadenoma, severe fibrocystic mastopathy and cystosarcoma phyllodes and so on. After a period of 1-38 months follow-up postoperatively, the results were satisfactory with no significant complications. It is believed that the breast repair by utilizing silicone gel-filled implant following mastectomy is a safe, reliable and more effective procedure, and is reasonable to extend its indication in latter clinical application.

Differential proliferative response to linoleate in cultures of epithelial cells from normal human breast and fibroadenomas.
Human breast epithelial cells isolated from normal breast tissues of premenopausal women demonstrated direct evidence of a proliferative effect by linoleate (18:2 omega 6) or prostaglandin E2 (PGE2) in the presence of insulin and epidermal growth factor in serum-free cultures within a collagen gel matrix. Neither epidermal growth factor nor 18:2 omega 6 by itself was capable of stimulating growth but together they stimulated proliferation synergistically. Epithelial cells isolated from fibroadenomas on the other hand failed to exhibit any growth stimulation due to 18:2 omega 6 or PGE2. The linoleate-stimulated growth in normal breast epithelial cells was inhibited by indomethacin, a cyclooxygenase inhibitor, which however could be reversed by PGE2. The proliferative response of normal breast epithelial cells to 18:2 omega 6 was accompanied by a greater conversion of [14C]18:2 omega 6 to arachidonic acid and [14C]20:4 omega 6 to prostaglandins than that seen in epithelial cells from fibroadenomas. The turnover of [14C]18:2 omega 6 in the phospholipids of normal cells was higher than in fibroadenomas indicating a possible role of phospholipids in mediating the 18:2 omega 6 effect in normal cells. Both normal and fibroadenoma cells can proliferate in response to cholera toxin and glucocorticoids when supplemented to the insulin- and epidermal growth factor-containing medium. From the results it appears that, unlike normal cells, fibroadenoma cells may have a specific defect in the PGE2-responsive cyclic AMP-generating mechanism whereas cholera toxin-induced mechanism is operative in both types of cells.

[Enzymo-immunoassay of progesterone receptors in human breast lesions and tumors. Comparison with a biochemical method].
The determination of progesterone receptors (RP) was performed on 80 benign and malignant human breast tumors with a single saturating dose method (10 nM) using dextran-coated charcoal (PR-Bio) and an enzymo-immunoassay (PgR-EIA). There was a significant correlation between the 2 methods qualitatively (P less than 0.001) and quantitatively (r = 0.79). However the results were significantly higher using the PgR-EIA method than the PR-Bio method (P = 0.04) with a regression line Y = 0.81 x +0.58.

Fine-needle aspiration in the management of breast masses.
The exact role of FNA in the diagnosis of palpable breast lesions is still uncertain. False-positive and false-negative cytological diagnoses occur and raise questions regarding the diagnostic utility of FNA as a replacement for open biopsy in many clinical situations. False-positive diagnoses may result from atypical epithelial proliferations, fibroadenomas, or inflammatory lesions. False-negative aspirates may occur because of technical errors, cystic lesions, and underdiagnosis of low grade neoplasms. The triple diagnosis protocol has been suggested as a replacement for open biopsy of palpable breast masses in many clinical situations. Following this algorithm, the results of palpation, mammography, and cytology are combined to guide management. Mammography should precede FNA or follow the cytologic procedure by 2 or more weeks. Patients with a positive triple diagnosis should undergo open biopsy or confirmatory intraoperative frozen section. Positive FNA results would be useful for preoperative counselling as well as serving as a diagnostic procedure for clinically suspicious lesions in patients wishing a confirmatory test before open biopsy is performed. Patients with discordant triplet results should be referred for open biopsy. The management of patients with negative triplet results is less clear. From the available data, it appears that approximately 2 percent of patients with negative triplet results have carcinoma. Based on these results, we cannot recommend replacing open biopsy by the triple diagnosis method in most patients with a persistent dominant mass. In most cases, a biopsy is indicated. Surgeons, who plan to follow a breast mass with clinical examination, may be able to reduce their false-negative rate by performing FNA. Further study is necessary to establish the best way to use FNA in the diagnosis of breast carcinoma, to determine the cost effectiveness of the triple diagnosis method as a substitute for open biopsy, and to assess the utility of aspiration cytology in the mammographically directed diagnosis of nonpalpable breast lesions.

[Mammary fibroadenoma showing osseous metaplasia: a case report].
Discussed is a 33-year-old premenopausal woman who noted a mass in her right breast. On palpation, the tumor was determined as being 3.5 x 2.5 cm in size, well circumscribed, of a firm consistency, and freely movable. Mammography showed a well-defined oval lesion which contained a coarse calcification in the upper external quadrant. An ultrasound study revealed a well-defined oval low echoic lesion with a high echoic portion in the internal echo. The tumor was extirpated and a gross inspection found it to be an ordinary fibroadenoma, 3.2 x 2.5 x 1.5 cm in size. Histologically the lesion was a hyalinized fibroadenoma showing osseous metaplasia. A review of the literature has not revealed cases of a benign breast tumors showing an osseous and/or cartilagenous metaplasia. Notable however is that many reports show mammary osteosarcomas as originating from a fibroadenoma. Thus, this tumor also might have possibly developed into a osteosarcoma.

[How great is the risk of cancer and recurrence following benign breast biopsy?].
Four hundred and thirty-eight patients with biopsy-proven benign breast disease were followed annually in a prospective manner for 4-17 years, to analyze breast cancer risk, correlations with cancer development and recurrence during follow-up. Twelve breast cancers developed in 12 patients during follow-up, giving a 2.6 fold increased cancer risk over the reference population. No association was found between patients who developed cancer and those who did not with respect to the initial histologic feature (p = 0.9), the age at entry by decades (p = 0.4) and relative to menopause (p = 0.3), the presence of cysts (p = 0.5) or calcification (p = 0.2) in the biopsy specimen, a family history of breast cancer (p = 0.7) or the follow-up time (p = 0.9). Benign breast disease does not inevitably lead to recurrence. Moreover, 47% of the 438 patients never had any recurrence and were free of symptoms during follow-up, and 84% never required a further operation. We conclude that an aggressive approach to benign breast disease is not justified, for any type of lesion as defined in this report.
