Abstract
In order to assess the utility of the tumor-associated antigen CA15-3 in the diagnosis of breast cancer, this new tumor marker was measured pre-operatively in 1342 patients. This group comprised 509 patients with malignant disease (134 with breast cancer and 375 with other malignancies not involving the breast) and 833 patients with benign surgical diseases (95 patients with fibroadenoma of the breast, 738 with other benign diseases). The results were compared with those for carcino-embryonic antigen (CEA) in the diagnosis of breast cancer. CA15-3 was above the normal limits of 25 U/ml in 31% of the patients with breast cancer, in 22% of patients with other malignancies, and in 9% of patients with benign diseases. CEA was elevated in 26% of patients with breast cancer (> 3ng/ml). CA15-3 levels were above 50 U/ml in 13% of the breast cancer patients, in 6%) of patients with other malignancies, and in 0.2% of the patients with benign diseases. There was a good correlation between CA 15-3 level and tumor stage in breast cancer. CA 15-3 serum levels were over 50 U/ml in respectively 0%, 2%, 13%, and 73% of the patients with stages I, II, III, and IV. CA 15-3 and CEA were also determined in 671 patients who had received initial curative surgery of breast cancer, and who regularly attended our follow-up clinic. CA15-3 was found to be more sensitive than CEA in detecting recurrences of breast cancer. In the post-care period, carcinoma recurred in 205 patients. Of these 73% had CA15-3 concentrations above 25 U/ml, whereas only 50% had CEA values above 3 ng/ml (p< 0.0001). Although neither CA15-3 nor CEA are sensitive enough for the screening and diagnosis of early breast cancer, CA 15-3 is superior to CEA in the detection of breast cancer metastases.

Abstract
Aims and Background We evaluate the possibility to use a combination of techniques such as lymphocyte stimulation and the Cell Scan instrument for early detection of breast cancer. This method can detect differences in lymphocytes activation in the presence or absence of cancer. Methods The Cell Scan is a static cytometer system able to examine cellular membrane polarization. We screened 88 women with benign breast lesions, 207 women with mammary carcinoma and 325 healthy blood donors. After lymphocytes separation, each blood sample was incubated with encephalitogenic factor (EF), phytohaemagglutinin (PHA) and Breast Antigen (BrAg) then SCM test was performed. Results Positivity was 50% among breast cancer patients, 34% among women affected by benign disease and 27% and 22% respectively among healthy female and male controls with an increase of the specific predictivity of the test during the period of ovulation. A significant difference ( P <0.0001) was observed between healthy donors and breast cancer patients. Conclusions This results suggest that the Cell Scan test could be useful to investigate patient's immunogenicity to molecules known to be involved in tumor development and progression, such as oncogene or suppressor gene products, which could be appropriate targets for immune-derived therapeutic approaches.

Abstract
The topographic distribution of a mucinous-like cancer antigen (MCA) recognized by a monoclonal antibody b-12 (MAb b-12) was assessed in benign (38) and malignant (66) breast tissues. The reactivity of MAb b-12 showed a good selectivity for breast tissues, reacting both with normal tissues and breast cancer. The degree of MCA expression was evaluated in the various groups of breast pathology adopting quantitative criteria of assessment. With the criteria of evaluation adopted, strong staining was observed in 71.4% breast carcinomas. The most positive reaction was demonstrated in mucinous carcinoma. MCA distribution in breast tissue was compared with the distribution of two other antigens, CEA and TPA. Reactivity of MAb b-12 was higher than the reactivity shown by the anti-CEA and anti-TPA antibodies.

Abstract
Although the relations between diabetes mellitus (DM) and breast cancer (BC) are lately widely discussed, the actual causes for cancer predisposition in patients with diabetes are currently unclear. This study was designed to define the frequency of DM immunological predictors occurrence and immune system function shifts in patients with breast cancer. Sixty four BC patients, 19 patients with benign breast conditions and 40 healthy individuals were included. The lymphocyte sensibilization with insulin suppressed by prostaglandin-synthesizing cells or cells with histamine receptor expression (DM predictor) is more common in BC patients than in control group (29 of 56 vs 5 of 37, p < 0.001). This is not a tumor marker, but rather is an objective factor reflecting higher occurrence of insulin resistance in this group. For BC patients is also characteristic the lower PHA-stimulated peripheral lymphocyte proliferation rate probably caused by increase in short-lived suppressor cell activity, a usual sign of the impairment of cell-mediated immunity. It is also possible, that the immunologic predictors of DM associated with insulin resistance, combined with the effects of short-lived suppressor cells, promote tumor cell proliferation.

Abstract
BACKGROUND Previous studies have demonstrated a high prevalence of thyroperoxidase antibodies (TPOAb) and autoimmune hypothyroidism in breast cancer (BC). These studies have been performed in BC patients generally 20-30 days after mastectomy. It is known that stress may have an influence on the immune system and a relation between stressful events and the onset or worsening of autoimmune thyroid disorders has been reported by several authors. The aim of the study was to evaluate the prevalence of autoimmune thyroid disease in patients with nodular breast disease selected for surgery before any treatment. Our hypothesis was that the high prevalence of thyroid autoimmune disorders in BC is independent of stressful events represented by surgery and/or anaesthetic procedures. METHODS Our series included 61 consecutive women aged 52.8 +/- 10.2 yrs (mean age +/- s.d.) with nodular breast disease selected for breast surgery: 36 out of 61 of them (59%) had BC and 25 out of 61 had benign breast disease (BBD). Controls included 100 healthy age-matched women. All patients and control subjects were submitted to clinical, ultrasound thyroid evaluation and serum-free thyroxine (FT4), serum-free tri-iodothyronine (FT3), TSH, TPOAb and thyroglobulin antibodies (TgAb) determination. RESULTS Mean FT3, FT4 and TSH concentration showed no differences between BC patients, BBD patients and controls. The prevalence of TPOAb in BC patients (12/36: 33.33%) was significantly higher than in BBD patients (5/25: 20%) (P < 0.01) and in controls (8/100: 8%) (P < 0.01). Similarly, the prevalence of TgAb in BC patients was 12 out of 36 (33.33%) significantly higher than that detected in BBD patients (4/25: 16%) (P < 0.01) and in controls (12/100: 12%) (P < 0.01). Of the 36 BC patients, 20 showed a diffuse hypoechogenicity of the thyroid gland to ultrasound evaluation, significantly higher than in BBD (7/25: 28%) (P = 0.03). Of the 20 BC patients who showed a hypoechogenic pattern of thyroid gland, 10 (50%) were associated with antithyroid antibodies positivity (TAb). This finding was present in two of seven BBD (28.57%) (P < 0.0001). Only two controls showed focal hypoechogenicity of the thyroid gland. Generally, 24 out of 36 (66.7%) of BC and 9 out of 25 (36%) of BBD (P = 0.02) had signs of thyroid autoimmunity consistent with the hypoechogenic pattern of thyroid gland associated or not with TAb; 2 out of 36 (5.55%) of BC and 1 out of 25 (4%) of BBD patients had autoimmune hypothyroidism and no hypothyroidism was found in controls. CONCLUSIONS The results of this study confirm the strong relation between thyroid autoimmunity and BC. This finding is independent of stressful events represented by surgery or anaesthetic procedures. The present data call attention to the usefulness of screening for autoimmune thyroid disorders in patients with nodular breast disease selected for surgery.

Abstract
Two cases of diffuse dermal angiomatosis are reported in middle-aged women. This rare disease of unknown origin is characterized by increased dermal angiomatosis and ulceration. The clinical and histologic presentations of the presently reported lesions were typical for this disorder. Endothelial cells exhibited a normal immunophenotype. The perivascular basement membranes showed a distribution of collagen alpha chains typical for blood vessels, but not for lymphatics. Immunohistochemistry revealed other undescribed features. At the site of the clinical lesions, linear and granular deposits of immunoglobulins A and M, and complement were found around the vessels and at the dermal-epidermal junction. The same deposits were also found restricted to the dermal-epidermal junction in the peripheral clinically intact skin. No serological signs of auto-immune disorder were detected in one patient. A monoclonal gammopathy was disclosed in the other patient. A pattern of immunoreactant deposits similar to that disclosed in the two patients was not found in the control specimens, and has not been described so far in other types of vascular hyperplasia and neoplasia. A pathogenic role of these deposits is unsettled and should be further explored.

Abstract
The aim of this study was to identify the aerobic and the anaerobic microorganisms which can be related to duct ectasia. The patients were divided into two groups. Group 1 comprised 100 patients with coloured nipple discharge (duct ectasia group), and Group 2 (the control group) was composed of 50 patients without nipple discharge. The culture media used were BHI-PRAS, blood agar, mannitol agar and MacConkey agar. There was a high frequency of bacterial growth in the two groups: 85% in Group 1 and 88% in Group 2. The most prevalent bacteria were Staphylococcus aureus and Staphylococcus epidermidis. There was a statistically significant higher rate of smokers in the duct ectasia group compared with the control group, 25 (25%) patients vs. 5 (10%), respectively (p = 0.03). These findings allow us to put forth the hypothesis that the genesis of duct ectasia may be a non-infectious inflammatory process.

Abstract
CONTEXT Localized breast lesions have been described in lupic or diabetic patients. However, the description of breast gigantomastia in women presenting with autoimmune diseases has not been reported. SETTING The study took place within the Department of Endocrinology and Reproductive Medicine, Necker Hospital, Paris, France. PATIENTS We describe eight patients with inflammatory gigantomastia, occurring in a context of immune-mediated diseases: myasthenia, chronic arthritis, or thyroiditis. MAIN OUTCOME MEASURES Together with hormonal, immunological, and breast magnetic resonance imaging (MRI) evaluation, breast histology enabled us to perform immunocytochemical and indirect immunofluorescence studies. Control sera were obtained from patients with (n = 10) and without (n = 7) antinuclear antibodies. RESULTS Six of the eight patients developed gigantomastia either at puberty or during pregnancy. Neither a hormonal oversecretion nor a specific immunological pattern was observed. All patients except one presented antinuclear antibodies. Histological study revealed a diffuse, stromal hyperplasia and a severe atrophy of the lobules. A rarefaction of adipocytes was also noted, as previously suggested on MRI. There was a perilobular lymphocytic infiltrate made of CD3+ lymphocytes. Study of sera from five of six cases of gigantomastia showed a nuclear immunofluorescence pattern in normal mammary ductal and lobular glandular epithelium, as well as in kidney and intestine epithelial cells. In control sera, a nuclear signal was observed only when antinuclear antibodies were present. CONCLUSIONS We suggest that breast tissue may be a target tissue in autoimmune diseases, this process being favored by the hormonal milieu. However, the precise mechanism of such association is not individualized. The fact that stromal hyperplasia is the main histological feature justifies the search for the involvement of growth factors in such a process.

Inflammatory pseudotumor of the breast in a patient with a high serum IgG4 level: histologic similarity to sclerosing pancreatitis. Am J Surg Pathol 2005; 29:275-8.

Abstract
The association between IgG4 and inflammatory pseudotumor was first reported with regard to pancreatic pseudotumor, which is well known as sclerosing pancreatitis or autoimmune pancreatitis. In addition, there is increasing evidence that IgG4 is also involved in inflammatory pseudotumor of the extrapancreatic tissue. In this report, we present a case of IgG4-related inflammatory pseudotumor of the breast. A 46-year-old woman presented with an induration in the left breast. Radiologic examination revealed an ill-circumscribed mass measuring 1.6 cm in diameter in the left breast. Breast cancer could not be ruled out radiologically, and excision biopsy was performed for a definite diagnosis. Histologically, this nodule was composed of an irregular proliferation of stromal cells associated with severe lymphoplasmacytic infiltration, obliterative phlebitis, and eosinophils. No atypical feature regarding the stromal cells or lymphocytes was observed. Furthermore, many plasma cells within the lesion were immunohistochemically positive for IgG4, and the serum IgG4 concentration of this patient was elevated on postoperative examination. This case suggests that inflammatory pseudotumor of the breast has a pathogenetic process similar to that of sclerosing pancreatitis. IgG4 might become a useful marker for inflammatory pseudotumor of the breast, and it might benefit from steroid therapy, as does sclerosing pancreatitis.

The role of anti-CENP-B and anti-SS-B antibodies in breast cancer. Neoplasma 2005; 52:32-5. [PMID: 15739023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/01/2023]
Abstract
A close relationship between autoimmunity and malignant diseases has been supposed for a long time. In clinical practice, anti-SS-B and anti-CENP-B antibodies are used as serologic markers for autoimmune diseases. In this study, anti-SS-B and anti-CENP-B autoantibodies were studied in breast cancer patients and compared to a control group surgically treated due to benign diseases. These antibodies were evaluated by enzyme linked immunoassay and serum values >10 U/ml were accepted as positive. Fifty-five patients with breast cancer and 25 patients with benign diseases were prospectively included in the study. In the breast cancer group, both anti-CENP-B (33% vs. 8%) and anti-SS-B (44% vs. 24%) autoantibodies had higher positivity compared to the control group, but this difference reached statistical significance only for anti-CENP-B antibodies (p=0.02). Besides, anti-SS-B positivity was detected more frequently in breast cancer patients with axillary involvement (63% vs. 24%) (p=0.006) and increased as the number of involved lymph nodes increased in the axilla (p=0.03). Although the clinical significance of autoantibody detection in cancer patients is still not clear, autoantibodies especially detected in individuals without proven autoimmune diseases needs to be thoroughly evaluated for early diagnosis and treatment of various cancers.

Abstract
BACKGROUND It has been reported that the number of mast cells was significantly greater in malignant breast carcinomas than in benign breast lesions. This was due to tryptase-containing mast cells while tryptase, chymase-containing mast cells had no effect. However, analysis of mast cells in breast carcinomas and benign breast lesions based on their histological findings remains to be elucidated. METHODS Using immunohistochemical methods morphological examinations of mast cells were undertaken in benign and malignant breast tissues from 51 patients (30 benign, 21 malignant), which were formalin-fixed and paraffin-embedded. In the study with malignant breast tissues, samples of malignant tissues and adjacent healthy tissues were obtained from a single patient, and the number of mast cells was compared. RESULTS Among benign breast tissues, the number of mast cells in intracanalicular fibroadenoma was significantly lower than that in pericanalicular fibroadenoma as well as that in mastopathy. The number of mast cells was significantly greater in malignant lesions than that in benign lesions. The number of mast cells in scirrhous carcinoma and that in solid-tubular carcinoma were significantly increased compared with that in adjacent healthy tissues. In addition, the number of mast cells in scirrhous carcinoma was highest among breast carcinomas, and significantly greater than that in papillotubular carcinoma. CONCLUSION We were the first to find the significant lower number of mast cells in intracanalicular breast fibroadenoma when compared with that in pericanalicular fibroadenoma as well as that in mastopathy. Moreover, the number of mast cells in scirrhous carcinoma was significantly greater than that in papillotubular carcinoma.

Abstract
IgG binding to purified mouse mammary tumor virus (MuMTV) was quantitated by an enzyme-linked immunoassay (ELISA) using sera from patients with breast cancer or benign breast disease, or from healthy age-matched controls. Significantly greater binding (p<0.01) was found in breast-cancer-derived sera than in the other categories. In addition to IgG reactivity, three breast cancer sera also possessed IgA and IgM reactive with MuMTV by the ELISA assay. Only IgG was reactive in the majority of sera while two sera possessed MuMTV binding activity only in the IgM fraction. Both IgG binding and virolysis of MuMTV were greatly reduced by preincubation of sera with MuMTV. The specificity for MuMTV was further explored with IgG of serum from one breast cancer patient. Human antibody reactive with MuMTV was progressively diminished by preincubating the human serum with increasing concentrations of MuMTV but not by incubation with the type-C AKR murine leukemia virus. Preincubation of MuMTV with a breast cancer serum partially blocked the reactivity of gp52 antiserum with the virus. The results suggest that an antigen related to an MuMTV envelope component is expressed in breast cancer.

Abstract
Mastalgia is a common condition that is thought to be hormonally related, but the mechanisms of pain causation are unknown. Inflammatory cytokines are implicated in pain modulation, but have not been studied with regard to mastalgia. We compared the relationship of mastalgia to the expression of the cytokines interleukin (IL)-6, IL-1beta, and tumor necrosis factor (TNF)-alpha and the degree of tissue infiltration with inflammatory cells in breast tissue from 29 premenopausal women with breast pain and 29 age-matched pain-free controls. Paraffin sections from breast biopsy samples were scored for the presence of inflammatory infiltrate and were evaluated for the expression of IL-6, IL-1beta, and TNF-alpha using standard immunohistochemical procedures. TNF-alpha and IL-6 expression displayed a trend toward slightly lower values in patients with pain (median TNF-alpha score, 3 versus 5; median IL-6 score, 3 versus 4). In the luteal phase, patients with mastalgia showed a trend toward lower expression of IL-6 (p = 0.4) in comparison to those without pain. A similar trend was also seen with TNF-alpha expression (p = 0.4). IL-1beta expression was extremely scant in the first 30 samples and was not investigated further. The degree of inflammatory infiltrate in the tissue was unrelated to the presence of breast pain. These data suggest that the three cytokines tested in this study do not play a significant role in the causation of mastalgia and lend weight to the previous finding that there are no identifiable histologic correlates of this troubling condition. Further investigation of the role of cytokines in breast pain is warranted, especially in view of the possible association between mastalgia and breast cancer risk.

Abstract
Lymphocytic mastitis and diabetic mastopathy are uncommon fibroinflammatory breast diseases. The lesions seen in these entities are unique in that the associated lymphoid infiltrates are composed of predominantly B cells. In addition, B-cell lymphoepithelial lesions, a finding commonly associated with extranodal marginal zone B-cell/mucosa-associated lymphoid tissue (MALT) lymphomas, are also often present in lymphocytic mastitis and diabetic mastopathy. Although the clinical and immunomorphologic features are well characterized, the clonality of the B-cell infiltrate and the lymphomatous potential of lymphocytic mastitis and diabetic mastopathy have not been emphasized in the literature. We evaluated 11 cases of lymphocytic mastitis/diabetic mastopathy for immunoglobulin heavy chain gene rearrangement and correlated the findings with all available clinical data. A longstanding history of Type I diabetes mellitus was present in seven patients. One nondiabetic patient had Sjogren's syndrome, and two patients had no history of diabetes mellitus or other autoimmune disease. Clinical data were unavailable for one patient. B-cell-predominant lymphoid infiltrates were seen in all cases, and B-cell lymphoepithelial lesions were found in five. No evidence of a B-cell clone was found in any of the 11 cases by appropriately controlled immunoglobulin heavy chain gene rearrangement studies, and none of the patients developed lymphoma during follow-up intervals ranging from 2-126 months. These findings suggest that despite the presence of B-cell-predominant lymphoid infiltrates and lymphoepithelial lesions, lymphocytic mastitis and diabetic mastopathy do not appear to be associated with an increased risk for lymphoma.

Abstract
BACKGROUND The UNI antigen (Ag) is a 120 kDa sialoglycoprotein which has been primarily found in human undifferentiated CD3dim thymocytes and leukemic T-cell lines, but subsequently also detected in solid tumors. We studied the expression of this Ag in a panel of normal and pathological breast tissues. MATERIALS AND METHODS Analysis of UN1 Ag expression on tissue specimens was performed by immunohistochemistry and Western blotting. RESULTS No Ag expression was found in 14 sections of normal tissue and 10 sections of benign nonproliferative lesions. Progressively increasing levels of UN1 Ag expression were found in fibroadenomas (24 positive out of 27 cases), proliferative lesions (9 cases), in situ (17 cases) and invasive carcinomas (56 cases). Finally, the highest expression was observed in 10 metastatic lesions. CONCLUSION These data suggest that UN1 Ag is a promising marker of potential value for immunophenotyping studies and therapeutic applications in breast diseases.

Abstract
Mammary duct ectasia/periductal mastitis is exceedingly rare in males. Ten cases have been reported in the literature, the last 2 cases were associated with Human immunodeficiency virus. The previously reported cases presented in females with blood stained discharge or subareolar inflammatory process. All cases required surgical treatment, 7 out of 10 cases underwent a form of mastectomy. To the best of our knowledge this disease entity was not reported in patients suffering from Behcets disease. This article described 2 new cases, one of them is a young man who had associated Behcets disease. An immune mechanism may be responsible for such association, which was not reported before. The clinical presentation, pathological findings and management of these 2 new cases were outlined followed by literature review.

Abstract
Abstract
Context.—We recently described a patient with chronic lymphocytic leukemia who presented with a breast carcinoma that stained positive for CD5 using a commercially available antibody (CD5-4C7, Novocastra, Newcastle upon Tyne, UK).
Objectives.—To study the distribution of CD5 immunoreactivity in tissue sections of a variety of benign and malignant breast lesions using the antibody CD5-4C7 and to compare the results with those obtained with 2 other commercially available CD5 antibodies (CD5/54/F6, Dako, Ely, Cambridgeshire, UK, and CD5/54/B4, Novocastra).
Design.—Paraffin sections of 102 breast biopsy specimens with various diagnoses were examined using the avidin-biotin immunoperoxidase complex technique.
Setting.—The histopathology department of a tertiary referral teaching hospital.
Results.—The staining results obtained with CD5-4C7 were different from those obtained with the other 2 antibodies. With 4C7, the normal and benign biopsy specimens showed varying numbers of positive epithelial cells and lymphocytes. Heterogeneous positive staining was also present in 47 (78%) of 60 invasive female breast carcinomas and in all 3 male breast carcinomas examined. A statistically significant correlation was found between CD5 positivity and tumor grade, with grade 3 tumors being less likely to be CD5 positive than grades 1 and 2 (P = .0035). No correlation was found between CD5 positivity and patient's age, tumor histologic type, axillary lymph node status, or progesterone receptors. On the other hand, the CD5/54/F6 and CD5/54/B4 antibodies only stained lymphocytes and occasional normal breast ducts, mostly those showing apocrine metaplasia. All other normal benign and malignant epithelial cells were negative.
Conclusions.—Positive staining for CD5 using the antibody 4C7 is seen in normal and benign breast tissue and 78% of invasive breast carcinomas. The positivity is more common in low-grade tumors. No significant staining was seen with the 2 other CD5 clones used in this study. The significance of the positive staining obtained with CD5-4C7 is not obvious, but this clone may be more sensitive than the others, or it may be recognizing an epitope shared by another antigen.

Abstract
The diagnostic value of the decrease in percentage of immunoglobulin G1 (%lgG1) in breast cancer was analyzed with special emphasis on early tumor stages. IgG1 and total IgG were preoperatively measured in the sera of a total of 801 individuals using a modified quantitative affinity chromatography. Group A consisted of 174 healthy individuals of both sexes, group B of 324 female patients with benign breast disease, and group C of 303 patients with invasive and non-invasive breast cancer. Within group C, 13 patients presented with intraductal carcinoma, and 22 patients with a pT1a-tumour (diameter less than 0.5 cm). The %IgG1 values were compared among groups A, B and C. In addition, correlations were sought between %IgG1 values of group C and tumor size, stage (UICC), histopathological grade and oestrogen (ER) and progesteron receptor (PR) expression. The mean value of %IgG1 in group A was 63.3 +/- 0.5 s.e.m., in group B 57.75 +/- 0.4 s.e.m. and in group C 52.37 +/- 0.5 s.e.m. The differences of mean values were highly significant between all three groups. Sensitivity and specificity of %IgG1 to discriminate between group A and C were 75% and 87%, and between group B and C 62% and 63%, respectively. The significant decrease of %IgG1 in total serum IgG is able to distinguish patients with breast cancer of more than 5 mm in diameter from healthy controls and patients with benign breast diseases. Finally, calculated posterior probabilities revealed that within certain concentration limits %lgG1 may provide predictive information with high probabilities.

Abstract
BACKGROUND The search for new tumor markers for breast carcinoma has been an area of vigorous study; nonetheless, to the authors' knowledge little new information has emerged beyond the clinical usefulness of CA 15-3. The authors studied serum CYFRA 21-1 in breast carcinoma based on evidence that breast carcinoma expresses cytokeratin 19 fragments and that CYFRA 21-1 is a specific antigen for cytokeratin 19 fragments. METHODS The serum samples of 86 patients with primary breast carcinoma, 14 patients with recurrent breast carcinoma, 22 patients with benign mammary disease, and 25 healthy controls were provided for measurements of CYFRA 21-1, carcinoembryonic antigen (CEA), and CA 15-3. The relation between clinicopathologic features, prognosis, and disease free survival with serum CYFRA 21-1 titers was studied. RESULTS There was no difference between the serum CYFRA 21-1 titers from patients with benign mammary disease and those from healthy controls. The sensitivities of CYFRA 21-1 for patients with International Union Against Cancer Stage IV and recurrent tumors were 60% and 64.2%, respectively, which were as high as those for CA 15-3 and superior to those for CEA. The hematogenous recurrence showed a very high sensitivity of 89%. According to the increments of T, N, and M factor numbers, the serum CYFRA 21-1 titers were elevated. No correlation between CYFRA 21-1 and CEA was observed and the correlation between CYFRA 21-1 and CA 15-3 was weak. The univariate and multivariate analyses for survival revealed that serum CYFRA 21-1 levels were an independent indicator of prognosis. CONCLUSIONS The measurement of the serum CYFRA 21-1 titer in patients with breast carcinoma may be useful in monitoring for recurrence and evaluating the therapeutic effect in patients with advanced disease.

Abstract
Castleman's disease is a rare lymph node pathology characterized by angiofollicular hyperplasia. There are two forms of the disease: localized and systemic, with different features, symptoms and prognosis. Three are the histological types of disease: plasma cell, hyaline-vascular and mixed variants. We report the case of a 65-year-old female affected by localized plasma cell variant of Castleman's disease. The singularity of our case lies in its localization on the breast and monoclonal plasma cell proliferation inside the nodule.

Abstract
Benign proliferative nipple duct lesions (PNDLs) pose a diagnostic problem for clinicians and pathologists. Clinically, they may be associated with skin changes typically present in Paget's disease of the nipple. The identification of numerous scattered cells in the epidermis that are immunoreactive for low-molecular-weight cytokeratin may lead to further confusion with Paget's disease. We studied the nipple epidermis in nine cases of PNDL and compared them with 26 histologically normal nipples from mastectomy specimens. CAM 5.2 and anticytokeratin 7 (CK7) immunoreactive cells were identified in the epidermis of seven of nine nipples associated with PNDL. The cytokeratin-positive cells appeared cytologically benign and were dispersed singly (scattered in seven of seven cases and frequent in four of seven cases) or formed small aggregates with occasional tubular structures (three of seven cases) in the basal and middle layers of the epidermis. In two of seven cases, these epidermal immunoreactive cells showed continuity with the underlying PNDL, suggesting the spread or continuation of lesional cells to the epidermis. Dispersed single immunoreactive cells were identified in small numbers (scattered) in the basal layer of the epidermis in 12 of 26 normal nipples and more frequently in 1 of 12 cases. In all cases, the intraepidermal cells were negative for carcinoembryonic antigen (CEA) and Her-2/neu. We conclude that intraepidermal CAM 5.2 and anti-CK7 immunoreactive cells, which are normally present in the nipple epidermis, may proliferate and form aggregates when there is an underlying PNDL. The presence of these cells does not imply Paget's disease when the intraepidermal cells have a bland cytologic appearance, fail to overexpress Her-2/neu, and there is no carcinoma within the PNDL or elsewhere in the breast.

Abstract
A large surgical wound is required for implantation of silicone mammary devices. Formation of capsules around silicone devices follows wound healing processes except that the healing is conformed and significantly delayed by the physical presence of the implant. Multilayered capsules are thicker and lymphocytic and plasmalymphocytic vasculitis, markers for delayed hypersensitivity, also correlate with thicker capsules. Polyurethane-coated devices induce very thick capsules that remain so for over 20 years. By contrast, gel and saline content devices show maximum thickness at 6. 5 years. Active T(H) lymphocyte memory does not differ by implant type for individuals with devices in place and that for gel content devices peaks at 10.5 years. There was a significant decrease in T cell indexes only after the removal of saline content devices. Comparison of the rate of formation of the periprosthetic capsule with the healing time of large wounds of similar size indicates that silicone devices interfere with the healing process, requiring substantially more time. This extended period has the potential for enhancing autoimmune conversion as a consequence of persistent delayed hypersensitivity.

Abstract
We performed a serological analysis for anti-p21WAF1/CIP1 antibodies in sera of patients with different gynecological diseases such as breast cancer, ovarian carcinoma, cervix carcinoma and benign gynecological tissue alterations and from healthy blood donors using the immunoblotting technique with recombinant p21WAF1/CIP1 as antigen as well as a newly designed ELISA. We detected antibodies specific for p21WAF1/CIP1 in sera derived from cancer patients, as well as from patients with non-malignant diseases and from healthy blood donors. Thus, the presence of antibodies against p21WAF1/CIP1 is not a marker for malignancies. Some of the sera with antibodies against p21WAF1/CIP1 also contained antibodies against the oncoprotein mdm2, and/or the growth suppressor gene product p53. The presence of antibodies against p53 correlates with a malignant disease.

Abstract
Expression of gangliosides is affected in various ways by malignant cell transformation. In the present study, we investigated the expression of CDw60, a constituent of O-acetylated disialogangliosides, in benign and atypical proliferative breast diseases, and preinvasive and invasive carcinomas by immunohistochemistry and thin-layer chromatography (TLC). In normal ducts, antibodies to CDw60 (mAb M-T21) reacted to membranes of the Golgi apparatus in the juxtaluminal cell compartment. A similar polarized distribution of Golgi cisterns in epithelial cells was observed in several benign lesions, i.e., fibroadenomas, intraductal papillomas, and gynecomastia. In contrast, blunt duct adenosis and duct hyperplasia exhibited an abnormal cytosolic and cell surface staining, whereas atypical duct hyperplasia showed randomly dispersed immunoreactive Golgi cisterns, indicating loss of epithelial polarity. In mammary carcinomas and in two breast carcinoma cell lines (MCF-7 and EFM-19) the neoplastic cells contained CDw60-immunolabelled Golgi complexes, which were distributed in a disorderly fashion throughout the cytoplasm, thus reflecting a loss of epithelial polarity. Additionally, only well differentiated ductal carcinomas in situ or invasive ductal carcinomas disclosed a strong cell surface labelling, which was absent in lower differentiated carcinomas of the same types. In all carcinomas, the intensity of CDw60 immunostaining decreased with progressing loss of differentiation (grade of dedifferentiation), as demonstrated by staining intensity in paraffin sections and by evaluation of the relative amounts of extracted 9-O-acetyl GD3 by TLC. Our results indicate that abnormal CDw60 expression is already detectable in benign proliferative breast lesions with different risk rates to develop into malignant lesions. Downregulation of CDw60 expression in poorly differentiated invasive carcinomas may be the consequence of loss of cell functions usually associated with poor prognosis.

Abstract
Parsis, the sole surviving group of followers of Zoroaster who are settled in Bombay, have a fourfold higher incidence of breast cancer than the general population of Greater Bombay. CD44 expression was studied by immunohistochemistry in breast cancers of 50 non-Parsi and 35 Parsi women, 10 normal breast tissues, 10 proliferative lesions and 49 tissues adjoining a tumor mass. α2 and β1 integrins could be studied in only 42 malignant cases and five normal tissues. The immunohistochemistry results were correlated with other parameters including tumor grade and size, estrogen and progesterone receptor status, lymph node involvement and mitotic index. CD44 was not expressed in normal areas. Benign areas and tissues adjacent to tumor masses showed increased staining. Both Parsi and non-Parsi women showed significantly high CD44 expression. All Parsi ILCs were strongly positive for CD44. In both groups ER negativity was associated with strong CD44 positivity, while mitotic counts correlated with decreased CD44 expression in Parsis but not in non-Par-sis. α2 and β1 integrins were strongly expressed on the baso-lateral surface of normal epithelium. However, they were downregulated in tumors. In general breast tumor tissues from Parsi and non-Parsi patients did not differ significantly with respect to most parameters. However, among Parsis lymph node involvement and CD44 correlated weakly whereas the mitotic index was inversely correlated with CD44. The reverse was true for non-Parsis. The deviation from the general pattern needs further study based on a large number of samples and appropriate use of splice variants.

Abstract
A case of bullous pemphigoid responding to niacinamide as monotherapy is reported. Clinically, the patient presented with bullous lesions localized to the left breast. She had a history of a left breast mastectomy for breast cancer. This was followed by radiation therapy to the left chest wall and delayed left breast reconstruction achieved with a transposition flap of the latissimus dorsi muscle. There have been reports of bullous pemphigoid treated with a combination of tetracycline and niacinamide. This is the first report, to our knowledge, of a case of bullous pemphigoid responding to niacinamide alone.

Abstract
The aim of the study was to test the cytotoxic activity of peripheral blood natural killer (NK) cells in relation to serum levels of sex hormones in patients with mastopathy. The study included 37 patients classified into mastalgia, fibrosis, fibrocystic disease, and fibroadenoma groups and 19 healthy age-matched volunteer women. Estradiol, progesterone, luteinizing hormone (LH), follicle-stimulating hormone (FSH), and prolactin were evaluated in sera by specific radioimmunoassays. NK cell activity was evaluated by means of 51Cr-release assay. In all patient groups, progesterone levels were significantly decreased. There was also an increased frequency of patients with low levels of estradiol (< 50 pg/ml). On the other hand, LH levels in fibrocystic disease and fibroadenoma groups were significantly increased. NK cell activity was in the normal range in all patient groups. In individual women, NK cell cytotoxicity did not correlate with the levels of the studied hormones. However, in patients with low (< 50 pg/ml) and high (> 200 pg/ml) estradiol levels an increase and a decrease of NK cell activity was observed, respectively. This suggests that in patients with mastopathy, estradiol may directly or indirectly affect NK cell cytotoxicity. High levels of estradiol and low NK cell activity might constitute an increased risk for neoplasia.

Abstract
The contribution of a cellular immune response to tissue destruction in sclerosing lymphocytic lobulitis of the breast is not well understood. In this study, comparison of one case with two age matched control cases showed an increased frequency of activated perforin mRNA expressing cells at the site of tissue destruction in lobulitis. Along with the detection of tumour necrosis factor alpha (TNF alpha) mRNA expressing cells in the infiltrates, the striking association of perforin expressing activated cytotoxic cells with remaining gland parenchyma and the high level of perforin mRNA suggests activation of cytotoxic cells in situ. These findings are evidence that cell mediated cytotoxicity plays a significant role in the destruction of mammary gland tissue in sclerosing lymphocytic lobulitis.

Abstract
We investigated the in vivo expression of cyclin B1 and Cdc2 (key molecules for G2-M transition during the cell cycle) in nonmalignant and cancerous human breast lesions using immunohistochemistry and quantitative proliferative index (PI) analysis. Breast epithelial cells co-expressed cyclin B1 and Cdc2 in their cytoplasm in the G2 phase and in their nuclei in the M phase. Cyclin B1, but not Cdc2, immunostaining rapidly disappeared from the nuclei during the mitotic metaphase to anaphase transition. Static image analysis revealed the mean proliferative index for cyclin B1/cdc2 for each type of lesion to be as follows: normal glands (n = 20), 2.0/2.5%; benign lesions, including typical ductal hyperplasia (n = 76), 2.5/5.8%; atypical ductal hyperplasia (n = 21), 3.0/6.6%; carcinomas in situ (n = 70), 7.4/14.0%; and invasive carcinomas (n = 58), 10.0/22.9%. Proliferative index data for atypical hyperplasia were virtually identical to those for benign lesions and were significantly lower than those for breast cancer, suggesting that expression levels of cyclin B1 and Cdc2 may be used to distinguish premalignant human breast lesions from advanced disease. Furthermore, the proliferative index for cyclin B1 for comedo-type ductal carcinomas in situ agreed with that for invasive ductal carcinomas (mean, 10.1% versus 9.5%), apparently explaining the clinicopathological aggressiveness of this tumor at the molecular level.

Abstract
Serial serum Carcinoembryonic antigen (CEA) levels were measured in 150 individuals (50 patients with breast cancer, 50 benign breast diseases and 50 other controls). These levels were correlated with clinicopathological parameters and follow-up information. Serum CEA levels were independent of the primary tumor status, their histology, lymphoreticular response and the patients' characteristics as well as the age, sex and the menstrual status. However, the nodal status, number of involved nodes and the grade of the tumors had significant influence on the level of serum CEA. Breast cancer patients especially those with metastasis had significantly higher serum CEA levels as compared to the controls and those with localised disease, irrespective of the site of metastasis. These levels were lowered appreciably by the disease regression and were raised or stable during the disease progression. Receiver operating characteristic (ROC) curve showed metastasis to be more frequent in patients with pretreatment serum CEA levels above 25 ng/ml and persistent post treatment CEA levels above 15 ng/ml. Serum CEA level was found to be a valuable prognostic indicator for advanced breast cancer and serial serum CEA levels provided an average lead time of about 3.9 months before the clinical appearance of metastasis.

Abstract
Tissue Polypeptide Specific-Antigen (TPS), a marker of cell proliferation, was evaluated in 258 patients, 216 with breast carcinoma and 42 with benign breast disease. TPS was measured pre-operatively in 98 patients and correlated with stage of disease showing a progression from Stage I through to Stage IV disease. TPS increased with increasing tumour size, however, TPS levels did not correlate with the number of involved lymph nodes. TPS was measured during follow-up in 118 patients, 64 had no evidence of recurrence, 23 had evidence of loco-regional recurrence and 31 had evidence of metastatic disease. TPS levels were significantly elevated in all categories of recurrence and were highest in patients with disseminated disease. Patients with elevated TPS during follow-up were more likely to experience disease progression on further follow-up. This preliminary study demonstrates that this marker may be useful as an index of tumour burden and deserves further evaluation in a large population to determine whether it can aid in the identification and follow-up of patients with recurrent disease.

Abstract
Fifteen samples of non-tumoural breast tissue, 24 cases of benign lesions, four biopsies of inflammatory carcinomas and 94 tumour samples of primitive mammary carcinomas were analysed for HLA class II expression. We found, first, that HLA class II antigens were detectable in all cases of non-neoplastic breast tissue. Secondly, HLA class II antigen expression was notably increased in benign neoplasms and hyperplastic lesions. In contrast, only 32 out of 94 carcinomas showed expression of HLA-DR antigens, 17 tumours had HLA-DP antigens and 11 carcinomas were positive for the presence of DQ molecules. The expression of class II antigen was associated with the degree of histological differentiation (P < 0.05) but was independent of stromal leucocytic infiltration. Thirdly, HLA-DR was very strongly expressed in intravascular tumoural thrombi, especially in the 'inflammatory carcinomas'. The immunophenotype of inflammatory infiltrate was analysed in benign and malignant lesions. In malignant lesions the mean number of inflammatory cells was significantly higher than in benign lesions. Interestingly, we found no differences in the amount and composition of inflammatory infiltrate between HLA-DR positive and negative tumours.

Abstract
The aim of this study was to examine tissue from patients with breast carcinoma or benign breast disease for the presence of monoclonal-antibody-defined antigens, including the MUC1 mucin and carcinoembryonic antigen CEA. The tests were performed by sodium dodecyl sulphate/polyacrylamide gel electrophoretic separation of proteins, electrophoretic transfer to nitrocellulose membranes and immunostaining with the monoclonal antibodies. Some of the antigens identified are known to circulate at high levels in some but not necessarily all, breast carcinoma patients. Serum from a panel of ten breast cancer patients was subjected to a fractionation procedure designed to release antigen from immune complexes, and again these samples were analysed for the presence of monoclonal-antibody-defined antigens. A high frequency of positive reactions was detected by the anti-MUC1 monoclonal antibody C595 with both breast carcinoma subcellular membrane fractions as well as antigen fractions eluted from circulating immune complexes. No reactions were observed with equivalent materials from benign breast disease samples. The findings illustrate the variability in antigen expression between breast tumours. The data also indicate that a proportion of patients respond to their tumour by the production of antibodies that recognise the MUC1 antigen in their circulation.

Abstract
AIMS To study the immunohistochemical expression of carcinoembryonic antigen (CEA) in ductal hyperplasia of the breast and to investigate its putative relation with atypia and co-existing infiltrating ductal carcinoma. METHODS Paraffin wax embedded tissue from 37 cases of isolated ductal hyperplasia (five with atypia and 32 without atypia) and 25 cases of ductal hyperplasia associated infiltrating ductal carcinoma (IDC) (seven with atypia and 18 without atypia) was stained with a monoclonal anti-CEA antibody using a standard avidin biotin immunoperoxidase method. RESULTS CEA immunoreactivity was observed in eight (12.8%) ductal hyperplasia cases. The percentage of CEA positivity in ductal hyperplasia cases with atypia (33.3%) was substantially higher than that observed in cases of ductal hyperplasia without atypia (8.0%). Six cases of ductal hyperplasia associated IDC reacted with CEA; in these six cases the neoplastic cells of the co-existing carcinoma were also CEA positive. The percentage of CEA immunoreactivity in ductal hyperplasia associated IDC was higher than that observed in isolated ductal hyperplasia (24.0 v 5.4%). The percentage of CEA immunoreactivity in atypical ductal hyperplasia associated IDC was similar to that observed in IDC alone (42.9 v 40.0%). CONCLUSIONS The presence of CEA immunoreactivity has been confirmed in benign proliferative breast lesions. The prevalence of such immunoreactivity increases from 3.1% in isolated, nonatypical ductal hyperplasia to 42.9% in atypical ductal hyperplasia associated IDC. This finding and the similarity of the frequency of CEA positivity in atypical ductal hyperplasia associated IDC and in IDC alone suggests that there is a pathogenetic link between ductal hyperplasia and some types of breast cancer.

Abstract
We evaluated 100 referred women with breast implants (n = 97) or silicone fluid injections (n = 3) into breasts who developed various symptoms. All reported symptoms occurred at a median latency period of 6 years (range 0-24 years) after implantation or injection of silicone. Commonest symptoms were weakness (95%), fatigability (95%), myalgia (90%), morning stiffness (89%), arthralgia (81%), memory loss (81%), sensory loss (77%), headache (73%) and dry eyes and dry mouth (72%). Laboratory results revealed abnormal levels of serum immunoglobulins or complement in 57% and autoantibodies in 78%. Sural nerve biopsy was abnormal in 80% with the major finding of loss of myelinated fibers in 79%. Biceps muscle biopsy was abnormal in 58% with the major finding of neurogenic atrophy in 27%. Ninety-six patients underwent implant removal; 60% of the patients were found to have one or both implants ruptured with silicone spilled into tissue. At time of removal, a pectoralis major muscle biopsy was taken which was abnormal in 89% with the major finding of neurogenic atrophy in 55%. Biopsy of implant capsule was abnormal in 94% showing foreign body giant cells containing refractile material consistent with silicone in 69% whether or not the elastomer shell was ruptured. Silicone can cause a systemic autoimmune disease with a variety of symptoms probably due to a global activation of the immune system. Since our patients had objective laboratory and histologic findings together with a high rate of mechanical implant failure, further investigations are necessary.

Fine-needle aspirates and paraffin-embedded tissue sections from 91 cases with diverse breast diseases were immunostained with carcinoembryonic antigen (CEA) monoclonal antibody using a BioGenex StrAviGen kit based on the biotin-streptavidin amplified methodology. The results were compared with histopathologic tumor type and tumor stage. CEA was not expressed in fibrocystic changes with mild or florid epithelial hyperplasia (n = 23) and fibroadenomas (n = 8). On the other hand, 90% (56/60) of primary breast carcinomas showed positive cytoplasmic staining for CEA. No correlation was found between CEA expression, histopathologic tumor type, and tumor stage. We suggest that CEA immunocytochemistry will help in the accurate diagnosis of primary breast carcinoma in fine-needle aspirates in addition to the usual cytological criteria.

Abstract
BACKGROUND It has been thought that carbohydrate antigens, especially Lewis (Le) blood group antigens, are cancer-related antigens. METHODS The authors conducted immunohistochemical studies to investigate the expression of seven different types of Le carbohydrate antigens in breast cancer tissue and their usefulness as an indicator of the degree of malignancy and as a prognostic factor. RESULTS When this expression was compared in the cancerous portion of 300 breast cancers and noncancerous mammary ductal epithelium in each of the patients, reduced expression of type 1 carbohydrate antigens and increased expression of type 2 carbohydrate antigens were found in the cancerous portions. No correlation was detected between the antigen expression and clinicopathologic factors. The prognosis of patients in whom type 2 carbohydrate antigens were increased in the cancerous portion, especially Lex (19.7% of patients) and sialyl Lex-i (20.3% of patients), was poorer than in patients in whom they were not increased (P < 0.01). CONCLUSIONS The relative expression of type 2 carbohydrate antigens in breast cancer tissue seems capable of serving as a prognostic factor.

Abstract
Alterations on the cell surface of the oligosaccharide portion of glycoproteins and glycolipids are thought to play a role in tumorigenesis. Sialyltransferase catalyzes the incorporation of sialic acid to the carbohydrate group of glycoconjugates. Sialyltransferase has been found elevated in different tumour tissues and in the serum of cancer patients. In the present study we have examined the expression of the beta-galactosyl alpha 2,6-sialyltransferase requiring epitope CDw75, with the monoclonal antibody HH2. 142 breast lesions were included. 21% of the carcinomas in situ and 35% of the invasive carcinomas showed a diffuse cytoplasmic staining. Seven cases of invasive carcinomas also showed a distinct membrane immunoreactivity. We found no correlation between reactivity for CDw75 in malignant lesions and their metastatic potential. Only five out of 11 primary tumours with metastases expressed CDw75 in the primary tumour. In the benign lesions, there was a positive reaction in proliferating lesions, e.g. intraductal papillomas (2 out of 3 cases) and in epithelial proliferations in fibrocystic disease (10 out of 14 cases). None of the four fibroadenomas and phyllodes tumours and only one out of 22 cases of normal breast tissues showed immunoreactivity for HH2. In the malignant lesions, CDw75 was more frequently expressed in the carcinomas of high malignancy grade. The high frequency of immunoreactivity among the benign breast lesions can be indicative of activation of the epithelial cells.

Abstract
The study was conducted on 63 patients with breast lump and twenty normal healthy females. In benign breast disease, a significant (P < 0.001) rise in serum IgA, significant (P < 0.001) decrease in IgG and no change in IgM levels was seen before operation. A significant decrease (P < 0.001) in serum IgA and significant increase in IgG and IgM was observed post operatively. In carcinoma breast, a significant (P < 0.001) elevation in IgA, IgG and IgM levels was found pre-operatively with a concomitant decrease in serum IgA and IgG and increase in serum IgM levels, post operatively. Trans-sternal phlebography (TSP) carried out with 95.23% success has revealed significant (P < 0.001) change in the staging of carcinoma breast. The increased levels of serum immunoglobulins associated with the patients of carcinoma breast with metastasis has led to conclude that these levels, if punctuated with TSP findings can lead to better assessment of the staging of carcinoma breast and thereby its management.

Thrombospondin and other possible related matrix proteins in malignant and benign breast disease. An immunohistochemical study. THE AMERICAN JOURNAL OF PATHOLOGY 1992; 140:1473-82.

Abstract
Thrombospondin (TSP), which plays an important hemostatic role, is a 450-kd cytoadhesive protein present in the alpha granules of platelets. In vitro experiments using cultured malignant cells suggest that it may help to mediate malignant cell attachment to extracellular matrix and may be important in cancer invasiveness. The authors studied a group of malignant and benign breast tissues for the expression of TSP and provide evidence that TSP may have a role in tumor invasiveness. Using immunohistochemical techniques, the authors found in 48 fresh specimens of breast carcinoma that TSP stained strongly in the desmoplastic stroma or at the basement membrane associated with the malignant ductal epithelium. Tumor cells abutting these tissues revealed cytoplasmic staining for TSP. Stronger TSP staining was seen in the poorly differentiated tumors. These findings were compared with those of normal and benign breast tissue, which showed no TSP staining apart from reactivity in the large distended cysts of fibrocystic disease and faint staining in the stroma of fibroadenomas. Staining for integrin was positive in lymphocytes of both malignant and benign breast disease and equivocally also in the stromal cells of the breast cancer tissue. Immunoreactivity to TSP in tissues was also compared with that of fibronectin, laminin, and collagen type I, III, and IV. The overall findings suggest that thrombospondin may have a role in the tumor biology of invasiveness.

Abstract
Episialin, a mucus glycoprotein, is a well-known tumor-associated antigen used in a variety of tests to detect the presence of adenocarcinoma. With the introduction of the microparticle-captured enzyme immunoassay (MEIA), a new technique was introduced. We compared this assay with our standard method to detect adenocarcinomas, the measurement of carcinoembryonic antigen (CEA). In breast cancer, the breast cancer mucin (BCM) assay was more often positive in metastatic disease but was not better than CEA in stages I-III. In lung carcinomas, BCM and CEA gave similar results while in colorectal carcinoma, CEA was superior. BCM gave similar results to CA 15.3 in a group of breast cancer patients.

Abstract
We describe 13 cases of inflammatory lesion of breast lobules in young and middle-aged women, presenting as breast lumps, with, in five cases, associated breast pain. The patient with the most florid bilateral disease subsequently developed Hashimoto's thyroiditis. This prompted us to consider an autoimmune pathogenesis for all the breast lesions. We confirm a previously documented association of such breast lesions with diabetes mellitus and review the evidence for a possible HLA association. Increased HLA-DR expression by breast epithelial cells was observed in cases available for study. Of the seven patients screened for circulating autoantibodies, three had none, one had smooth muscle antibodies, one parietal cell, one parietal cell and thyroid microsomal, and the seventh had the thyroid autoantibodies expected in Hashimoto's disease. Five of seven patients whose HLA-status was determined were HLA-DR3, 4 or 5 positive, either singly or in combination. Immunophenotypic analysis of the mammary lymphoid infiltrate showed that the majority of infiltrating lymphocytes were B-cells.

Abstract
Immunostaining for glial fibrillary acidic protein (GFAP) identifies a minor subpopulation of immunoreactive myoepithelial cells in the normal resting human breast. The GFAP-immunoreactive cells also express a panel of myoepithelial cell markers, including cytokeratin 14 (CK 14), vimentin, smooth-muscle-specific actin isoforms, nerve growth factor receptor (NGFR) and common acute lymphoblastic leukaemia antigen (CALLA). The percentage of GFAP-immunoreactive myoepithelial cells is greatly increased in various neoplastic and non-neoplastic diseases of the breast, being highest in adenomyoepitheliomas. Furthermore, in all the instances of fibroadenoma, phyllodes tumour, epitheliosis and gynaecomastia, a variable number of epithelial cells also acquires immunoreactivity for GFAP, vimentin, CK 14, NGFR and, to a lesser extent, for CALLA. Conversely, GFAP immunoreactivity has never been encountered in the malignant cells of the different types of breast carcinoma. These findings suggest that the expression of GFAP might be a (possibly transient) feature of proliferating epithelial and myoepithelial cells in breast diseases other than carcinomas.

Abstract
The monoclonal antibody 323/A3 has been suggested as a marker of cancer risk in benign breast disease. Patients who have had both a benign biopsy and a later biopsy for breast carcinoma were studied. The staining patterns in the biopsies were analysed using a semi-quantitative recording system adapted from Mariani-Costantini et al. Immunohistochemical (IHC) staining was carried out on formalin fixed paraffin embedded tissue sections. In apocrine metaplasia the cytoplasm of benign tissue did not stain with 323/A3 whereas in the biopsies with associated breast cancer 5 of 7 biopsies stained, a statistically significant difference. A positive predictive value of 100% was noted for strong cytoplasmic staining to indicate the presence of carcinoma and this phenomenon may be useful as a means of demonstrating patients who have malignant breast disease in which a biopsy has inadequately sampled the breast tissue.
