Serum levels of total sialic acid (TSA), lipid bound sialic acid (LSA), heat stable alkaline phosphatase (HSAP) and fucose were measured in 39 patients with breast carcinoma, 14 patients with benign breast diseases and 35 healthy female individuals. Elevated levels of the four biomarkers in breast carcinoma were significant when compared with controls (p less than 0.001). Fucose levels were most sensitive (71.8%), while TSA levels were most specific (64.3%) for breast carcinoma. Sensitivity and specificity were 100% when combinations of LSA with fucose and TSA with HSAP were studied respectively. LSA was significantly elevated in infiltrating duct carcinoma patients compared with lobular carcinoma (p less than 0.001). TSA, HSAP and fucose also had lower mean values in lobular carcinoma as compared to infiltrating duct carcinoma. Increase in the levels of LSA and HSAP after surgical removal of the tumor in breast carcinoma occurred prior to the clinical evidence of the recurrence. The results indicate that the combination of the markers studied might be useful in breast cancer diagnosis and treatment monitoring.  相似文献

Microscopic review of 490 consecutive human breast biopsy and mastectomy specimens were correlated with estrogen and progesterone receptor content of the tissue, by subtype and degree of differentiation. Of the 4 grades of differentiation, the less differentiated Grade III and IV tumors showed significantly lower levels of estrogen and progesterone receptors in infiltrating ductal and lobular carcinoma (P less than 0.001). In contrast, patients with medullary carcinoma had the lowest tissue levels of estrogen and progesterone receptors with approximately 80% of the cases with less than 10 fmol/mg protein. Patients with mucinous carcinoma had the highest percentages of positive estrogen and progesterone receptor levels (75% and 87%, respectively). Sixty-three percent of the patients with Grade IV infiltrating ductal carcinoma were younger than 53 years of age (P less than 0.001). Patients younger than 53 years of age with Grade II and III infiltrating ductal carcinoma also had significantly lower levels of estrogen receptors, but not of progesterone receptors, than those patients older than 53 years of age (P less than 0.001). Nineteen of 20 "normal" breast tissue specimens were negative (less than 3 fmol/mg protein) for estrogen and progesterone receptors. About 50% of 17 tissue specimens from benign breast lesions (fibroadenoma, fibrocystic disease, sclerosing adenosis) showed positive estrogen (greater than 10 fmol/mg protein) or progesterone receptor values. In two patients with gynecomastia, no estrogen or progesterone receptors were detectable.  相似文献

To determine the influence of infiltrating lobular histology on local tumor control, the authors studied 49 patients with Stages I and II infiltrating lobular breast carcinoma treated by limited excision of the tumor and radiotherapy between 1968 and 1981 (median follow-up, 75 months). Results were compared with those in 561 cases of infiltrating ductal carcinoma similarly treated during the same period. The 5-year actuarial risk of local recurrence was similar for patients with infiltrating lobular or ductal carcinoma when the latter was evaluated as a single group (12% versus 11%). However, the 12% 5-year actuarial local recurrence risk for patients with infiltrating lobular carcinoma was intermediate between that for patients with infiltrating ductal carcinomas with an extensive intraductal component (23%) and those without an extensive intraductal component (5%). The pattern of recurrence in the breast was similar in the infiltrating lobular and ductal groups. All recurrences in patients with infiltrating lobular carcinoma and 80% of recurrences in the infiltrating ductal group occurred in the vicinity of the primary tumor (P = not significant). None of the clinical or morphologic features examined significantly influenced the risk of local recurrence in patients with infiltrating lobular carcinoma. The authors conclude that combined conservative surgery and radiotherapy appear to be a reasonable treatment option for patients with infiltrating lobular carcinoma, but further follow-up will be required to confirm these results.  相似文献

Serum trace elements and Cu/Zn ratio in breast cancer patients   总被引:8,自引:0,他引:8  
Serum copper, zinc, and the Cu/Zn ratio were measured in 55 patients with breast disease (20 with benign breast diseases and 35 patients with breast cancer) and 30 controls. The mean serum copper levels were higher in breast cancer than in benign breast diseases (167.3 micrograms/dl vs. 117.6 micrograms/dl) (P less than 0.001) and controls (167.3 micrograms/dl vs. 98.8 micrograms/dl) (P less than 0.001). Patients with advanced breast cancer had higher serum copper levels than did patients with early breast cancer (177.9 micrograms/dl vs. 130.4 micrograms/dl) (P less than 0.001). The mean serum zinc levels were lowered only in patients with advanced breast cancer as compared with controls (88.6 micrograms/dl vs. 115.1 micrograms/dl) (P less than 0.001). Serum zinc levels were not decreased in patients with early breast cancer and benign breast diseases. The Cu/Zn ratio was increased in breast cancer patients (1.91 vs. 0.86) (P less than 0.001) but not in patients with benign breast diseases. The precise mechanisms responsible for the alterations in trace element levels in breast cancer patients are still unclear and require further evaluation. However, the serum copper levels and the Cu/Zn ratio may be used as biochemical markers in these patients.  相似文献

The spectral morphometric characteristics of standard haematoxylin and eosin breast carcinoma specimens were evaluated by light microscopy combined with a spectral imaging system. Light intensity at each wavelength in the range of 450-800 nm was recorded for 10(4) pixels from each field and represented as transmitted light spectra. A library of six characteristic spectra served to scan the cells and reconstruct new images depicting the nuclear area occupied by each spectrum. Fifteen cases of infiltrating ductal carcinoma and six cases of lobular carcinoma were examined; nine of the infiltrating ductal carcinoma and three of the lobular carcinoma showed an in situ component. The spectral morphometric analysis revealed a correlation between specific patterns of spectra and different groups of breast carcinoma cells. The most consistent result was that lobular carcinoma cells of in situ and infiltrating components from all patients showed a similar spectral pattern, whereas ductal carcinoma cells displayed spectral variety. Comparison of the in situ and the infiltrating ductal solid, cribriform and comedo carcinoma cells from the same patient revealed a strong similarity of the spectral elements and their relative distribution in the nucleus. The spectrum designated as number 5 in the library incorporated more than 40% of the nuclear area in 74.08% of the infiltrating lobular cells and in 13.64% of the infiltrating ductal carcinoma cells (P < 0.001). Spectrum number 2 appeared in all infiltrating ductal cells examined and in none of the lobular cells. These results indicate that spectrum number 5 is related to infiltrating lobular carcinoma, whereas spectrum number 2 is characteristic for infiltrating ductal carcinoma cells. Spectral similarity mapping of central necrotic regions of comedo type in situ carcinoma revealed nuclear fragmentation into defined segments composed of highly condensed chromatin. We conclude that the spectral morphometric features found for lobular and ductal cell populations may serve future automated histological diagnostics.  相似文献

Carcinoembryonic antigen (CEA) has been shown to be a useful tumor marker in patients with breast carcinoma. The unlabeled antibody immunoperoxidase technique was used to localize CEA in 93 cases of primary breast carcinoma, 15 cases of atypical duct papillomatosis, and 4 cases of duct papilloma. Normal breast epithelium and breast epithelium in fibrocystic disease did not stain positively for CEA. Twenty-four of 27 (88%) intraductal carcinomas, and 47 of 69 (68%) infiltrating duct carcinomas were CEA positive. In contrast, only 5 of 21 (23%) in situ lobular carcinomas and 8 of 24 (33%) infiltrating lobular carcinomas were positive for CEA. All 15 cases of atypical epithelial papillomatosis were negative, whereas 1 of the 4 cases of duct papilloma exhibited microscopic foci of weak CEA positivity. There was a trend for infiltrating duct carcinomas, 3 cm in diameter or smaller, staining strongly positive for CEA, to be associated with synchronous axillary lymph node metastases (P = 0.09). Tumor heterogeneity was a constant feature of CEA staining with positivity varying from region to region and even from cell to cell. Positive immunohistochemical staining for CEA may play an adjunctive role in discriminating intraductal carcinoma from atypical papillary ductal proliferations.  相似文献

The role of the tumour marker CA-50 has been studied in the differential diagnosis of benign and malignant breast disease. Serum levels of CA-50 were determined by radioimmunoassay using a level of 17 units/ml as a cut-off. All 50 normal subjects and 22 of 24 patients (92%) with benign breast disease had CA-50 levels below 17 units/ml. By contrast, 15 of 36 patients (42%) with breast carcinoma had serum CA-50 levels above 17 units/ml (P less than 0.001). There was no clear correlation with tumour stage. The data suggest that CA-50 levels may help to differentiate benign and malignant diseases of the breast.  相似文献

ObjectiveConsidering the difficulty in detecting primary breast cancers using whole-body positron emission tomography (WBPET) owing to its limited spatial resolution, we aimed to evaluate the detectability of breast cancer by ring-type dedicated breast PET (DbPET) on the World Health Organization (WHO) histological classification in comparison with WBPET.MethodsA total of 938 patients with breast cancer underwent WBPET and ring-type DbPET, and 1021 lesions were histologically assessed based on the WHO classification of tumors of the breast. The findings of WBPET and DbPET were retrospectively evaluated and compared.ResultsThe size-related sensitivity of DbPET was superior to that of WBPET for subcentimetric tumors (81.9% vs. 52.4%, P < 0.001). The histological distribution was as follows: 11 lobular carcinoma in situ, 158 ductal carcinoma in situ, 738 infiltrating duct carcinoma not otherwise specified (NOS), 12 lobular carcinoma NOS, 40 mucinous adenocarcinoma, 13 tubular carcinoma, 36 invasive breast carcinoma others, and 13 papillary neoplasms. WBPET had low sensitivity for lobular carcinoma in situ, ductal carcinoma in situ, lobular carcinoma NOS, mucinous adenocarcinoma, and tubular carcinoma. DbPET showed improved sensitivity for all the above except lobular and tubular carcinoma. The maximum standardized uptake values (SUVmax) of DbPET were significantly higher than those of WBPET for histological types, excluding lobular carcinoma in situ. The SUVmax of papillary neoplasms was high regardless of low-grade histology and Ki-67 labeling index.ConclusionsDBPET was found to have high sensitivity and SUVmax values for all histologic types that showed low sensitivity of detection on WBPET, except lobular carcinoma in situ.  相似文献

Background: The role of conservative surgery and radiation therapy (CS and RT) in the treatment of patients with infiltrating ductal carcinoma is well established. However, the efficacy of CS and RT for patients with infiltrating lobular carcinoma is less well documented. The goal of this study was to examine treatment outcome after CS and RT for patients with infiltrating lobular carcinoma and to compare the results to those of patients with infiltrating ductal carcinoma and patients with mixed ductal–lobular histology. Methods: Between 1970 and 1986, 1624 patients with Stage I or II invasive breast cancer were treated with CS and RT consisting of a complete gross excision of the tumor and 6000cGy to the primary site. Slides were available for review for 1337 of these patients (82%). Of these, 93 had infiltrating lobular carcinoma, 1089 had infiltrating ductal carcinoma, and 59 had tumors with mixed ductal and lobular feature these patients constitute the study population. The median follow-up time for surviving patients was 133 months. A comprehensive list of clinical and pathologic features was evaluated for all patients. Additional histologic features assessed for patients with infiltrating lobular carcinoma included histologic subtype, multifocal invasion, stromal desmoplasia, and the presence of signet ring cells. Results: Five and 10-year crude results by site of first failure were similar for patients with infiltrating lobular, infiltrating ductal, and mixed histology. In particular, the 10-year crude local recurrence rates were 15%, 13%, and l3% for patients with infiltrating lobular, infiltrating ductal, and mixed histology, respectively. Ten-year distant/regional recurrence rates were 22%, 23%, and 20% for the three groups, respectively. In addition, the 10-year crude contralateral breast cancer rates were 4%, 13% and 6% for patients with infiltrating lobular, infiltrating ductal and mixed histology, respectively. In a multiple regression analysis which included established prognostic factors, histologic type was not significantly associated with either survival or time to recurrence. Conclusions: Patients with infiltrating lobular carcinoma have a similar outcome following CS and RT to patients with infiltrating ductal carcinoma and to patients with tumors that have mixed ductal and lobular features. We conclude that the presence of infiltrating lobular histology should not influence decisions regarding local therapy in patients with Stage I and II breast cancer.  相似文献

The records of 480 patients who received systemic therapy for advanced breast cancer in the University Hospital of South Manchester from 1975 to 1983 were examined. There were 264 with infiltrating duct carcinomas (IDC) and 33 with infiltrating lobular carcinomas (ILC) for whom the response to endocrine therapy was known. There were 92 responses (35%) among the IDC patients and 9 (27%) among the ILC patients. Sixty-seven per cent of IDC patients tested had steroid hormone receptor positive tumours compared to 90% for ILC (P < 0.001). Comparison of survival from diagnosis, disease free interval and survival from relapse showed no significant differences between the two groups. Thus despite almost of ILC patients having hormone receptor positive tumours their survival was similar to that of IDC patients. This appears to be due to a lower than expected response rate to endocrine therapy. This is a further indication of the different biological characteristics of these two histological sub-types of breast carcinoma.  相似文献

Because of carbohydrate alterations in malignant cells, serum glycoproteins have drawn considerable attention. In the current investigation we determined total sialic acid (TSA), lipid bound sialic acid (LSA), protein bound hexoses (galactose + mannose), fucose, hexosamines (galactosamine + glucosamine) and mucoid protein concentrations in the serum of patients with anemia and myeloid leukemia. The results were compared with those obtained in healthy individuals. In the leukemia patients we observed significant increases in glycoconjugates compared with the controls (P less than 0.001), and in TSA and fucose levels compared with the anemia patients (P less than 0.001). LSA and hexosamine levels were significantly lower in anemia patients with respect to the leukemia patients (P less than 0.01 and P less than 0.05 respectively), whereas levels of mucoid proteins and hexoses did not show significant differences. Except for hexosamines, all the markers tested were significantly elevated in the anemia patients compared with the controls. The present study suggests that the glycoconjugates investigated might be useful biochemical markers for differentiating anemic from leukemic conditions.  相似文献

The records of 365 patients with advanced carcinoma of the breast were examined to identify those with CNS involvement. Nineteen (5.2%) developed parenchymal cerebral deposits and 10 (2.7%) developed meningeal infiltration during the course of their disease. Parenchymal cerebral deposits were almost exclusively associated with infiltrating duct carcinoma (95%) and meningeal infiltration (carcinomatous meningitis) was almost exclusively associated with infiltrating lobular carcinoma. Meningeal infiltration occurred late in the course of advanced disease and was associated with diffuse involvement of the bone marrow and abdominal structures.  相似文献
