The study presents the results from intraoperative frozen section assessment of axillary sentinel lymph nodes (SLNs) in breast cancer. Routine histological frozen sections from one level were used, two sections stained with haematoxylin and eosin. Immunohistochemistry for cytokeratins was applied to the permanent SLN paraffin sections only. Axillary dissection was performed on all SLN-positive cases regardless of the size of the metastatic deposits. With a detection rate of 83%, 272 patients entered the study over a period of 46 months. A total of 61 cases were SLN positive by frozen section analysis. The paraffin sections gave an additional 23 SLN-positive cases. The false-negative rate for frozen sections was then 27% (23/84). Micrometastases were found in 28 of 84 cases, and macrometastases in 56. The false-negative rate of frozen sections for micrometastases was 71% (20/28), and for macrometastases 5% (3/56). A total of 73% (61/84) of the patients underwent axillary surgery as a one-step procedure.  相似文献

BACKGROUND: Japanese and German breast cancer cases differ substantially in the frequency of egfr amplification. AIMS: To unravel further the cytogenetic differences between Japanese and German breast cancer cases. METHODS: Forty one Japanese breast cancer cases were evaluated by means of comparative genomic hybridisation (CGH). The results were compared with the CGH results from 161 German breast cancer cases. RESULTS: The mean number of genetic alterations/case was significantly higher in German premenopausal patients with breast cancer than in their Japanese counterparts. Japanese breast cancer cases revealed a higher number of chromosome 17p losses. Losses of 8p were associated with oestrogen receptor (ER) negativity in Japanese patients with breast cancer, whereas in the German patients gains of 3q and 6q were associated with the lack of ER expression. CONCLUSIONS: The interethnic differences of invasive breast cancer are reflected by cytogenetic aberrations, which are also associated with the differential expression of the ER.  相似文献

While the etiology of breast cancer remains enigmatic, some recent reports have examined the role of human papillomavirus (HPV) in breast carcinogenesis. The purpose of this study was to determine the prevalence of HPV in breast cancer tissue using PCR analysis and sequencing. Fifty-four (54) fresh frozen breast cancers samples that were removed from a cohort of breast cancer patients were analyzed. Samples were tested for HPV using comprehensive PCR primers, and in situ hybridization was performed on paraffin embedded tissue sections. Findings were correlated with clinical and pathological characteristics. The HPV DNA prevalence in the breast cancer samples was 50% (27/54) with sequence analysis indicating all cases to be positive for HPV-18 type. While HPV patients were slightly younger, no correlation was noted for menopausal status or family history. HPV positive tumors were smaller with earlier T staging and demonstrated lesser nodal involvement compared to HPV negative cancers. In situ hybridization analyses proved negative. The high proportion of HPV positive breast cancers detected in this series using fresh frozen tissues cannot be dismissed, however the role of HPV in breast carcinogenesis remains unclear and may ultimately be ascertained by monitoring future breast cancer incidence amongst women vaccinated against high risk HPV types.  相似文献

Ninety women with recently diagnosed stage I or stage II breast cancer who had been admitted to the NIH Clinical Center and were participating in a randomized trial were entered onto this behavioral immunology protocol. Patients were immunologically and psychosocially assessed at baseline (approximately 5 days after surgery) and again at 3 and 15 months post surgery. All of the patients were followed up for a minimum of 5 years, and 60% of the patients were followed for 7 years or longer. Twenty-nine women in the study group reported disease recurrences over the entire follow-up period. Causal path modeling statistical techniques showed that natural killer (NK) cell activity was a strong predictor of disease outcome when the outcome variable was defined as recurrence v nonrecurrence of disease (chi 2 = 6.9, p less than .001). Higher NK cell activity at follow-up predicted disease-free survival over the follow-up period. When the disease outcome variable was operationally defined as time to recurrent disease, the psychosocial factors were more strongly predictive of the rate of disease progression for those who had a recurrence (chi 2 = -4.1, p less than .01), but NK cell activity was seemingly less relevant in this latter case. Overall, these findings suggest that including mood and potentially relevant immunological variables, along with important biological prognostic variables, in multivariate and prospective models such as those examined in this study, potentially contributes more to the explanation of greater outcome variance of early-stage breast cancer than has been believed in the past.  相似文献

Promoter hypermethylation has been shown to be a common mechanism for inactivation of tumor suppressor genes in breast cancer. The aim of this study was to investigate the prevalence of Slit2 promoter hypermethylation in both the tumor and serum samples of breast cancer patients with ductal carcinoma in situ (DCIS) or invasive breast carcinoma (IBC). The methylation status of Slit2 was investigated in 210 tissue samples (15 breast with no pathological findings, 26 DCIS, and 169 IBC samples) and 123 corresponding serum samples (15 breast with no pathological findings, 26 DCIS, and 82 IBC samples) using methylation-specific polymerase chain reaction. Immunohistochemical staining for Slit2 was also performed using tissue microarray blocks to determine whether Slit2 promoter hypermethylation correlated with loss of Slit2 expression. Slit2 promoter hypermethylation was not detected in breast tissue and serum samples from patients with no pathological findings. DCIS or IBC showed a statistically higher frequency of Slit2 promoter hypermethylation compared to breast with no pathological findings in both the tissue and serum samples; however, there were no statistically significant differences between DCIS and IBC samples. Similar Slit2 promoter hypermethylation patterns were seen in the tissue samples and corresponding serum specimens (p < 0.001). Slit2 promoter hypermethylation was associated with loss of Slit2 expression. These results suggest that Slit2 promoter hypermethylation appears to be responsible for functionally silencing Slit2 expression. Slit2 promoter hypermethylation may be considered as a possible serum marker for early detection of breast cancer.  相似文献

With the availability of monoclonal antibodies against the estrogen receptor (ER) it is possible to demonstrate the presence of ER immunohistochemically. Some of the antibodies are claimed to be reactive in formalin fixed, paraffin embedded tissue. We have evaluated the reactivity of one of these antibodies, D75 and found an acceptable reaction in routinely formalin fixed, paraffin embedded tissue. The antibody was applied to both primary and secondary tumors from a group of patients with recurrent breast cancer. The metastatic lesions consisted of lymph node metastases, bone marrow metastases, and liver metastases. While 41% of the primary tumors were ER-positive, this was only the case with 35%, 20%, and 17% of the lymph node, bone marrow, and liver metastases, respectively. The discordance between the ER-status of the primary tumor and the distant metastasis was 41% in cases of bone marrow metastases, and 44% in liver metastases. In most cases the shift was from an ER-positive primary tumor to an ER-negative metastasis. The results support the hypothesis that ER-negative tumor cells are probably more aggressive with a larger metastatic potential than the higher differentiated, ER-positive tumor cells.  相似文献

Objective(1) To report the number and type of emotional expressions (cues/concerns) raised by breast cancer patients; (2) to identify the influence of setting, patient characteristics, and doctor-patient interaction on emotional expression.Methods308 Italian-speaking female patients were recruited at their first breast cancer consultation. The visits were audio-recorded and analysed for number and type of emotional expressions (VR-CoDES). Oncologists’ interaction skills were rated by the VR-COPE. Socio-demographic, clinical and personality variables were gathered before the consultation. Clinical variables and oncologists’ evaluations of the patient were collected after.ResultsBreast cancer patients raised emotional issues mainly as cues. The setting (centre where the consultations took place), the oncologist’s attribution of anxiety, regardless of anxiety test screening (STAI-X1) score before the consultation, and the oncologist’s ability to pick up on patient’s worries, handle emotional needs or understand psychosocial condition were all positively related with the number of emotional expressions. More tightly structured consultations had fewer emotional expressions.ConclusionBoth contextual and interactional aspects have an impact on patient emotional expressions.Practice implicationsOncologists need to be trained to manage both the content and the process of medical consultation. Work organization of the consultation setting needs to be taken into account.  相似文献

BACKGROUND: The use of paraffin wax embedded tissue samples as a source of DNA for genotype analysis has been limited because of difficulties in DNA extraction and single nucleotide polymorphism (SNP) analysis.AIMS: To test the feasibility of applying the combination of a commonly used DNA isolation procedure, PureGene, and a high throughput SNP analysis method, the polymerase chain reaction (PCR)-INVADER assay, to genotype several types of paraffin wax embedded breast tissues. METHODS: Twenty formalin fixed, paraffin wax blocks were obtained from five participants in the Iowa women's health study. Each participant provided several types of tissue including normal lymph node, normal nipple/areola tissue, inflammatory/fibrotic breast tissue, or normal breast tissue, and tumour tissue. RESULTS: Good quality DNA (260/280 ratio >1.6) was obtained from all tissues. Normal lymph nodes yielded the largest amount of DNA (97.1 mug). DNA obtained from the samples was tested for a germline C1183T polymorphism in the MnSOD gene by three methods-PCR-RFLP (restriction fragment length polymorphism), INVADER assay, and PCR-INVADER assay. Of the 20 samples, PCR-RFLP genotyped 16, the PCR-INVADER assay 18, and the INVADER assay two. This methodology was then used to analyse five additional genotypes and confirmed the general applicability of the method. CONCLUSIONS: This study demonstrated the feasibility of (1) using several paraffin wax embedded breast tissues as a source of DNA for germline genetic analysis, with lymph nodes providing the highest yield, and (2) using the combination of a common extraction method with a high throughput SNP analysis method, the PCR-INVADER assay.  相似文献

Use of alternative medicine by women with early-stage breast cancer.   总被引:28,自引:0,他引:28  
BACKGROUND: We analyzed the use of alternative medicine by women who had received standard therapy for early-stage breast cancer diagnosed between September 1993 and September 1995. METHODS: A cohort of 480 patients with newly diagnosed early-stage breast cancer was recruited from a Massachusetts statewide cohort of women participating in a study of how women choose treatment for cancer. Alternative medical treatments, conventional therapies, and health-related quality of life were examined. RESULTS: New use of alternative medicine after surgery for breast cancer was common (reported by 28.1 percent of the women); such use was not associated with choices about standard medical therapies after we controlled for clinical and sociodemographic variables. A total of 10.6 percent of the women had used alternative medicine before they were given a diagnosis of breast cancer. Women who initiated the use of alternative medicine after surgery reported a worse quality of life than women who never used alternative medicine. Mental health scores were similar at base line among women who decided to use alternative medicine and those who did not, but three months after surgery the use of alternative medicine was independently associated with depression, fear of recurrence of cancer, lower scores for mental health and sexual satisfaction, and more physical symptoms as well as symptoms of greater intensity. All groups of women reported improving quality of life one year after surgery. CONCLUSIONS: Among women with newly diagnosed early-stage breast cancer who had been treated with standard therapies, new use of alternative medicine was a marker of greater psychosocial distress and worse quality of life.  相似文献

The diagnostic accuracy of frozen section (FS) examination and intraoperative cytology (IOC) has been compared in two different series of breast biopsies in which only one of the two methods has been used. The intraoperative results have been compared with the final histological diagnoses. Five-hundred-ten cases have been investigated by using FS only, and 407 by means of IOC. The two series were comparable because they included the same pathologies; moreover we have subdivided each series into four groups of pathologies to better evaluate the diagnostic accuracy of two methods. The total diagnostic accuracy of FS has been 93.13% vs. 95.-33% of IOC The value of diagnostic accuracy of FS and IOC in the four sub-groups substantially overlapped; there was only a little difference in the group of “various lesions” in which the diagnostic accuracy of IOC was higher. No false positive has been observed in IOC. FS have produced one false positive (0.19%), whereas false negatives have amounted to 1.77% for IOC and to 1.72% for FS. Deferred diagnoses have been 2.95% in IOC and 4.90% in FS examination. For both methods according to Galen and Gambino the following values have been calculated: sensitivity, specificity, efficiency, and predictive value. By comparing the data, the value of the cytological examination in the intraoperative diagnoses results is evident mainly when the latter is coupled with the gross observation. Causes of diagnostic errors clearly overlap both in IOC and in FS: (1) lesions with a fibroadenomatous appearance can involve an overdiagnosis or an underdiagnosis; (2) low-grade lesions like tubular carcinomas or in situ lobular carcinomas can be interpreted as benign; (3) the differential diagnosis of intraductal lesions may be very difficult, and a conservative approach is the best choice; and (4) infiltrating lobular carcinoma may be neglected both in FS and IOC. The few disadvantages of the cytologic method are offset by its low cost, the wider sampling, the possibility of sparing tissue for further investigations (such as steroid receptors, cellular kinetic, electron microscopy, and other biological studies) proved more useful in prognostic evaluation of breast cancer.  相似文献

OBJECTIVE: Hormones have been implicated as modulators of cognitive functioning. For instance, results of our previous work in women with breast cancer showed that cognitive impairment was more severe and involved more memory domains in those who received adjuvant tamoxifen therapy compared with women who received chemotherapy alone or no adjuvant therapy. Recently aromatase inhibitors such as anastrozole have been used in lieu of tamoxifen for the adjuvant treatment of postmenopausal women with hormone receptor-positive, early-stage breast cancer. Plasma estrogen levels are significantly lower in women who receive anastrozole compared with those who receive tamoxifen. We hypothesized, therefore, that anastrozole would have a more profound effect on cognitive function than tamoxifen, a mixed estrogen agonist/antagonist. DESIGN: To test this hypothesis we compared cognitive function in women with early-stage breast cancer who received tamoxifen with those who received anastrozole therapy in a cross-sectional study. We evaluated cognitive function, depression, anxiety, and fatigue in 31 postmenopausal women with early-stage breast cancer who were between the ages of 21 and 65 years and treated with tamoxifen or anastrozole for a minimum of 3 months. RESULTS: The results showed that women who received anastrozole had poorer verbal and visual learning and memory than women who received tamoxifen. CONCLUSIONS: Additional, prospective studies are needed to validate and confirm the changes in cognitive function associated with hormone therapy for breast cancer.  相似文献

Although the earliest feature of disseminated disease in breast cancer is regional lymph node involvement, little is known about the mechanisms whereby cancer cells interact with lymphatic endothelial cells and enter the lymphatic system. We have previously reported that the extensive presence of retraction clefts in breast carcinomas highly significantly correlates with lymphatic tumor spread and predicts poor outcome, suggesting that retraction clefts are not just fixation artifacts, but real potential spaces that are exaggerated by tissue processing and may reflect an early stage of lymphatic invasion. In this study, we examined the correlation between the extent of retraction clefts and lymphangiogenesis, as assessed by lymphatic vessel density and vascular endothelial growth factor-C (VEGF-C) expression in a series of 256 early-stage breast carcinomas. The presence and extent of retraction clefts around tumor cell nests was determined by review of all hematoxylin- and eosin-stained tumor sections. Lymphatic vessels were detected by podoplanin immunohistochemistry and lymphatic vessel density was measured using the hot-spot method. The expression of VEGF-C in the tumor cells was determined by immunohistochemistry and analyzed semiquantitatively on a four-tiered scale. High levels of retraction clefts, peritumor lymphatic vessel density and VEGF-C expression at the invasive edge in breast carcinomas significantly correlated with tumor size, histological grade, lymphatic invasion and nodal metastasis. Breast carcinomas showing extensive retraction clefts (>20% of tumor volume) were found to have significantly higher lymphatic vessel density and VEGF-C expression levels compared to tumors without this feature. High retraction clefts, peritumor lymphatic vessel density and VEGF-C expression predicted poor outcome in breast carcinomas. Our results support the hypothesis that retraction clefts are real potential spaces that may represent 'pre-lymphatic spaces' facilitating initial lymphatic invasion and that growth factors secreted by the tumor cells may stimulate tumor-associated lymphangiogenesis by promoting the endothelialization of these 'pre-lymphatic channels'.  相似文献

We examined the effects of a10-week, group-based cognitive-behavioral stressman-agement (CBSM) intervention on serum testosterone levels in women with Stage 1or 2 breast cancer. At 4 to 8 weeks postsurgery, participants were randomized to CBSM (n = 24) or to a wait-list control group (n = 10). Free and total testosterone was assessed via radioimmunoassay before and after the study period. The participants also completed a questionnaire assessing the degree to which living with breast cancer had led to social and emotional benefits in their life. We observed significant decreases in testosterone levels in the CBSM group and no change in the controls. Decreasesintes-tosterone were related to increases in positive contributions. These findings suggest that a short-term psychological intervention can help modulate androgen functioning, and these changes are related to enhanced benefit finding observed among women with breast cancer participating in CBSM.  相似文献
