  1. Histological evaluation of AMPK signalling in primary breast cancer

    International Nuclear Information System (INIS)

    AMP-activated protein kinase (AMPK) acts as a cellular fuel gauge that responds to energy stress by suppressing cell growth and biosynthetic processes, thus ensuring that energy-consuming processes proceed only if there are sufficient metabolic resources. Malfunction of the AMPK pathway may allow cancer cells to undergo uncontrolled proliferation irrespective of their molecular energy levels. The aim of this study was to examine the state of AMPK phosphorylation histologically in primary breast cancer in relation to clinical and pathological parameters. Immunohistochemistry was performed using antibodies to phospho-AMPK (pAMPK), phospho-Acetyl Co-A Carboxylase (pACC) an established target for AMPK, HER2, ERα, and Ki67 on Tissue Micro-Array (TMA) slides of two cohorts of 117 and 237 primary breast cancers. The quick score method was used for scoring and patterns of protein expression were compared with clinical and pathological data, including a minimum 5 years follow up. Reduced signal, compared with the strong expression in normal breast epithelium, using a pAMPK antibody was demonstrated in 101/113 (89.4%) and 217/236 (91.9%) of two cohorts of patients. pACC was significantly associated with pAMPK expression (p = 0.007 & p = 0.014 respectively). For both cohorts, reduced pAMPK signal was significantly associated with higher histological grade (p = 0.010 & p = 0.021 respectively) and axillary node metastasis (p = 0.061 & p = 0.039 respectively). No significant association was found between pAMPK and any of HER2, ERα, or Ki67 expression, disease-free survival or overall survival. This study extends in vitro evidence through immunohistochemistry to confirm that AMPK is dysfunctional in primary breast cancer. Reduced signalling via the AMPK pathway, and the inverse relationship with histological grade and axillary node metastasis, suggests that AMPK re-activation could have therapeutic potential in breast cancer

    Background The histologic grade (HG) of breast cancer is an established prognostic factor. The grade is usually reported on a scale ranging from 1 to 3, where grade 3 tumours are the most aggressive. However, grade 2 is associated with an intermediate risk of recurrence, and carries limited information for clinical decision-making. Patients classified as grade 2 are at risk of both under- and over-treatment. Methods RNA-sequencing analysis was conducted in a cohort of 275 women diagnosed with...

    Numerous studies have evaluated the association between factors related to maturation and reproduction and breast cancer risk, but few have assessed how these factors are related to different histologic types of breast cancer among postmenopausal women. We used polytomous logistic regression to assess the effect of age at maximum height and reproductive factors on risk of invasive breast cancer by histologic type in three case groups (524 ductal, 324 lobular, 196 ductal-lobular) and 469 contr...

  4. Histologic review of breast cancer cases in survivors of atomic bombs in Hiroshima and Nagasaki, Japan

    International Nuclear Information System (INIS)

    A panel of Japanese and American pathologists reviewed existing histologic material used to study breast cancer risk among the A-bomb survivors in Hiroshima and Nagasaki, a population in which incidence studies have found a strong relationship between breast cancer risk and radiation dose. The primary charge to the panel was to define a body of confirmed cases in the Life Span Study sample of the Radiation Effects Research Foundation that would require little or no review for inclusion in future studies of breast cancer incidence. Broad agreement on histologic type was reached for 298 of 300 confirmed cases. The distribution of histologic types was, overall, similar to that seen in other studies of breast cancer in Japanese women, and did not appear to depend on dose; thus radiation-induced breast cancer appeared to be no different histologically from other breast cancer. Also, no evidence was found of variation in histologic type by city, age at exposure, age at diagnosis, or calendar time

  6. Histological review of breast cancer in atomic bomb survivors, Hiroshima and Nagasaki

    International Nuclear Information System (INIS)

    A group of pathologists from the United States and Japan reviewed breast cancer material of women exposed to the atomic bombs in Hiroshima and Nagasaki and controls. The purpose of the review was to verify the diagnoses, establish a base of confirmed cases for epidemiologic study, and provide a reference for other pathology review. Compared to the control group, matched through the Life Span Study extended sample, there were no differences in distribution of tumor type and tumor size. There were also no differences in histological type by age or radiation dose. The peak age for cancer to develop was the same in the exposed and control groups. The type of radiation had no effect on histological type. Atypical changes or residual proliferative lesions were not found in women exposed to radiation but free from cancer. On the basis of this study, it was concluded that radiogenic breast cancer does not differ histologically from spontaneously occurring cancer in Japanese women. (author)

    Little is known about mutational landscape of rare breast cancer (BC) subtypes. The aim of the study was to apply next generation sequencing to three different subtypes of rare BCs in order to identify new genes related to cancer progression. We performed whole exome and targeted sequencing of 29 micropapillary, 23 metaplastic, and 27 pleomorphic lobular BCs. Micropapillary BCs exhibit a profile comparable to common BCs: PIK3CA, TP53, GATA3, and MAP2K4 were the most frequently mutated genes. Metaplastic BCs presented a high frequency of TP53 (78 %) and PIK3CA (48 %) mutations and were recurrently mutated on KDM6A (13 %), a gene involved in histone demethylation. Pleomorphic lobular carcinoma exhibited high mutation rate of PIK3CA (30 %), TP53 (22 %), and CDH1 (41 %) and also presented mutations in PYGM, a gene involved in glycogen metabolism, in 8 out of 27 samples (30 %). Further analyses of publicly available datasets showed that PYGM is dramatically underexpressed in common cancers as compared to normal tissues and that low expression in tumors is correlated with poor relapse-free survival. Immunohistochemical staining on formalin-fixed paraffin-embedded tissues available in our cohort of patients confirmed higher PYGM expression in normal breast tissue compared to equivalent tumoral zone. Next generation sequencing methods applied on rare cancer subtypes can serve as a useful tool in order to uncover new potential therapeutic targets. Sequencing of pleomorphic lobular carcinoma identified a high rate of alterations in PYGM. These findings emphasize the role of glycogen metabolism in cancer progression. PMID:26907767

    Full Text Available INTRODUCTION: Recently, growing evidence indicates that immunoglobulins (Igs are not only produced by mature B lymphocytes or plasma cells, but also by various normal cells types at immune privileged sites and neoplasm, including breast cancer. However, the association of breast cancer derived IgG with genesis and development of the disease has not yet been established. METHODS: In this study we examined the expression of IgG in 186 breast cancers, 20 benign breast lesions and 30 normal breast tissues. Both immunohistochemistry with antibodies to Igκ (immunoglobulin G κ light chain and Igγ (immunoglobulin G heavy chain and in situ hybridization with an antisense probe to IgG1 heavy chain constant region gene were performed. Various clinicopathological features were also analyzed. RESULTS: We found that IgG is specifically expressed in human breast cancer cells. Both infiltrating ductal carcinoma and infiltrating lobular carcinoma had significantly greater numbers of Igκ and Igγ positive cancer cells as compared with medullary carcinoma, carcinoma in situ, and benign lesions (all p<0.05. In addition, IgG expression was correlated with breast cancer histological subtypes (p<0.01 and AJCC stages (p<0.05, with more abundance of IgG expression in more malignant histological subtypes or in more advanced stage of the disease. CONCLUSIONS: IgG expression in breast cancer cells is correlated with malignancy and AJCC stages of the cancers. This suggests that breast cancer derived IgG may be associated with genesis, development and prognosis of the cancer.

  11. Nectin-4 is a new histological and serological tumor associated marker for breast cancer

    International Nuclear Information System (INIS)

    Breast cancer is a complex and heterogeneous disease at the molecular level. Evolution is difficult to predict according to classical histoclinical prognostic factors. Different studies highlight the importance of large-scale molecular expression analyses to improve taxonomy of breast cancer and prognostic classification. Identification of new molecular markers that refine this taxonomy and improve patient management is a priority in the field of breast cancer research. Nectins are cell adhesion molecules involved in the regulation of epithelial physiology. We present here Nectin-4/PVRL4 as a new histological and serological tumor associated marker for breast carcinoma. Expression of Nectin-4 protein was measured on a panel of 78 primary cells and cell lines from different origins and 57 breast tumors by FACS analysis and immunohistochemistry (IHC), respectively. mRNA expression was measured by quantitative PCR. Serum Nectin-4 was detected by ELISA and compared with CEA and CA15.3 markers, on panels of 45 sera from healthy donors, 53 sera from patients with non-metastatic breast carcinoma (MBC) at diagnosis, and 182 sera from patients with MBC. Distribution of histological/serological molecular markers and histoclinical parameters were compared using the standard Chi-2 test. Nectin-4 was not detected in normal breast epithelium. By contrast, Nectin-4 was expressed in 61% of ductal breast carcinoma vs 6% in lobular type. Expression of Nectin-4 strongly correlated with the basal-like markers EGFR, P53, and P-cadherin, and negatively correlated with the luminal-like markers ER, PR and GATA3. All but one ER/PR-negative tumors expressed Nectin-4. The detection of Nectin-4 in serum improves the follow-up of patients with MBC: the association CEA/CA15.3/Nectin-4 allowed to monitor 74% of these patients compared to 67% with the association CEA/CA15.3. Serum Nectin-4 is a marker of disease progression, and levels correlate with the number of metastases (P = 0.038). Serum

    Full Text Available The intra-tumor diversity of cancer cells is under intense investigation; however, little is known about the heterogeneity of the tumor microenvironment that is key to cancer progression and evolution. We aimed to assess the degree of microenvironmental heterogeneity in breast cancer and correlate this with genomic and clinical parameters.We developed a quantitative measure of microenvironmental heterogeneity along three spatial dimensions (3-D in solid tumors, termed the tumor ecosystem diversity index (EDI, using fully automated histology image analysis coupled with statistical measures commonly used in ecology. This measure was compared with disease-specific survival, key mutations, genome-wide copy number, and expression profiling data in a retrospective study of 510 breast cancer patients as a test set and 516 breast cancer patients as an independent validation set. In high-grade (grade 3 breast cancers, we uncovered a striking link between high microenvironmental heterogeneity measured by EDI and a poor prognosis that cannot be explained by tumor size, genomics, or any other data types. However, this association was not observed in low-grade (grade 1 and 2 breast cancers. The prognostic value of EDI was superior to known prognostic factors and was enhanced with the addition of TP53 mutation status (multivariate analysis test set, p = 9 × 10-4, hazard ratio = 1.47, 95% CI 1.17-1.84; validation set, p = 0.0011, hazard ratio = 1.78, 95% CI 1.26-2.52. Integration with genome-wide profiling data identified losses of specific genes on 4p14 and 5q13 that were enriched in grade 3 tumors with high microenvironmental diversity that also substratified patients into poor prognostic groups. Limitations of this study include the number of cell types included in the model, that EDI has prognostic value only in grade 3 tumors, and that our spatial heterogeneity measure was dependent on spatial scale and tumor size.To our knowledge, this is the first

    Full Text Available Abstract Background The potential problems associated with the use of formalin in histology, such as health hazards, degradation of RNA and cross-linking of proteins are well recognized. We describe the utilization of a formalin-free fixation and processing system for tissue detection of two important biopredictors in breast cancer – estrogen receptor and HER2 – at the RNA and protein levels. Methods Parallel sections of 62 cases of breast cancer were fixed in an alcohol-based molecular fixative and in formalin. Molecular fixative samples were processed by a novel formalin-free microwave-assisted processing system that preserves DNA, RNA and proteins. Formalin-fixed samples were processed using the conventional method. Estrogen receptor was assessed by immunohistochemistry and real-time PCR. HER2 was assessed by immunohistochemistry, FISH, CISH and real-time PCR. Results The immunohistochemical reaction for estrogen receptor was similar in molecular- and formalin-fixed samples (Spearman Rank R = 0.83, p Conclusion The formalin-free tissue fixation and processing system is a practical platform for evaluation of biomolecular markers in breast cancer and it allows reliable DNA and RNA and protein studies.

  15. Large-scale computations on histology images reveal grade-differentiating parameters for breast cancer

    International Nuclear Information System (INIS)

    Tumor classification is inexact and largely dependent on the qualitative pathological examination of the images of the tumor tissue slides. In this study, our aim was to develop an automated computational method to classify Hematoxylin and Eosin (H&E) stained tissue sections based on cancer tissue texture features. Image processing of histology slide images was used to detect and identify adipose tissue, extracellular matrix, morphologically distinct cell nuclei types, and the tubular architecture. The texture parameters derived from image analysis were then applied to classify images in a supervised classification scheme using histologic grade of a testing set as guidance. The histologic grade assigned by pathologists to invasive breast carcinoma images strongly correlated with both the presence and extent of cell nuclei with dispersed chromatin and the architecture, specifically the extent of presence of tubular cross sections. The two parameters that differentiated tumor grade found in this study were (1) the number density of cell nuclei with dispersed chromatin and (2) the number density of tubular cross sections identified through image processing as white blobs that were surrounded by a continuous string of cell nuclei. Classification based on subdivisions of a whole slide image containing a high concentration of cancer cell nuclei consistently agreed with the grade classification of the entire slide. The automated image analysis and classification presented in this study demonstrate the feasibility of developing clinically relevant classification of histology images based on micro- texture. This method provides pathologists an invaluable quantitative tool for evaluation of the components of the Nottingham system for breast tumor grading and avoid intra-observer variability thus increasing the consistency of the decision-making process

  1. Appearance of untreated bone metastases from breast cancer on FDG PET/CT: importance of histologic subtype

    To determine if the histology of a breast malignancy influences the appearance of untreated osseous metastases on FDG PET/CT. This retrospective study was performed under IRB waiver. Our Hospital Information System was screened for breast cancer patients who presented with osseous metastases, who underwent FDG PET/CT prior to systemic therapy or radiotherapy from 2009 to 2012. Patients with invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), or mixed ductal/lobular (MDL) histology were included. Patients with a history of other malignancies were excluded. PET/CT was evaluated, blinded to histology, to classify osseous metastases on a per-patient basis as sclerotic, lytic, mixed lytic/sclerotic, or occult on CT, and to record SUVmax for osseous metastases on PET. Following screening, 95 patients who met the inclusion criteria (74 IDC, 13 ILC, and 8 MDL) were included. ILC osseous metastases were more commonly sclerotic and demonstrated lower SUVmax than IDC metastases. In all IDC and MDL patients with osseous metastases, at least one was FDG-avid. For ILC, all patients with lytic or mixed osseous metastases demonstrated at least one FDG-avid metastasis; however, in only three of seven patients were sclerotic osseous metastases apparent on FDG PET. The histologic subtype of breast cancer affects the appearance of untreated osseous metastases on FDG PET/CT. In particular, non-FDG-avid sclerotic osseous metastases were more common in patients with ILC than in patients with IDC. Breast cancer histology should be considered when interpreting non-FDG-avid sclerotic osseous lesions on PET/CT, which may be more suspicious for metastases (rather than benign lesions) in patients with ILC.

    The indication for neoadjuvant chemotherapy (NAC) has recently broadened to include its use in the treatment of initial stage breast cancer. Axillary lymph node metastasis after NAC in breast cancer is a poor prognostic factor. Thus, the prediction of lymph node metastasis is important to estimate the prognosis of breast cancer patients after NAC. Therefore, we focused on residual carcinoma patterns of primary breast tumors after NAC and examined the correlation between the patterns and lymph node metastasis. In this study, we examined 50 breast cancer specimens and associated dissected lymph nodes after NAC. We divided 40 cases into an eradicated lymph node group and a residual lymph node group to analyze residual carcinoma patterns of primary breast tumors. Residual carcinoma patterns were classified according to the cell density of carcinoma cells: dense, focal/nested and sporadic/in-situ. There were significant differences in residual carcinoma patterns (P<0.01) among the three pattern groups. There was a high incidence of dense patterns in the residual lymph node group and a high incidence of sporadic/in-situ patterns in the eradicated lymph node group. Analysis of residual carcinoma patterns of primary breast tumors and clinicopathological factors demonstrated that there were significant differences in tumor reduced ratio on CT (P<0.001), primary tumor area before NAC (P<0.01), primary tumor area after NAC (P<0.00001), intrinsic subtype (P<0.01), Ki-67 labeling index (P<0.01), histological grade (P<0.05) and mitotic count (P<0.01) between the dense and non-dense groups. Therefore, our results suggest that the residual carcinoma pattern is useful for predicting eradicated or residual lymph nodes and the malignant potential in breast cancer after NAC. PMID:26935647

    More than 20-year follow-up of A-bomb survivors in Hiroshima and Nagasaki has a crucial role in determining the relationship of radiation to the occurrence of breast cancer. In 1967, Wanebo et al have first reported 27 cases of breast cancer during the period 1950-1966 among the Adult Health Study population of A-bomb survivors. Since then, follow-up surveys for breast cancer have been made using the Life Span Study (LSS) cohort, and the incidence of breast cancer has increased year by year; that is breast cancer was identified in 231 cases by the first LSS series (1950-1969), 360 cases by the second LSS series (1950-1974), 564 cases by the third LSS series (1950-1980), and 816 cases in the fourth LSS series (1950-1085). The third LSS series have revealed a high risk for radiation-induced breast cancer in women aged 10 or less at the time of exposure (ATE). Both relative and absolute risks are found to be decreased with increasing ages ATE. Based on the above-mentioned findings and other studies on persons exposed medical radiation, radiation-induced breast cancer is characterized by the following: (1) the incidence of breast cancer is linearly increased with increasing radiation doses; (2) both relative and absolute risks for breast cancer are high in younger persons ATE; (3) age distribution of breast cancer in proximally exposed A-bomb survivors is the same as that in both distally A-bomb survivors and non-exposed persons, and there is no difference in histology between the former and latter groups. Thus, immature mammary gland cells before the age of puberty are found to be most radiosensitive. (N.K.)

    Matrix metalloproteinases (MMPs) are proteolytic enzymes involved in the process of tumor invasion and metastasis that are found throughout tissues and also in the plasma. The aim of this study was to investigate whether the evaluation of plasma concentrations of MMPs 2, 3 and 9 may have clinical significance in breast cancer. Therefore, sera obtained from 80 patients with breast neoplasia (50 carcinomas and 30 fibroadenomas) were collected before and 96 h after surgery and the concentrations...

  6. Breast cancer histology and receptor status characterization in Asian Indian and Pakistani women in the U.S. - a SEER analysis

    International Nuclear Information System (INIS)

    Recent reports suggest increase in estrogen receptor (ER), progesterone receptor (PR) negative breast cancer yet little is known about histology or receptor status of breast cancer in Indian/Pakistani women.in the U.S. We examined the United States National Cancer Institute's Surveillance Epidemiology and End Results (SEER) Cancer program to assess: a) frequency of breast cancer by age, b) histologic subtypes, c) receptor status of breast cancer and, d) survival in Indians/Pakistanis compared to Caucasians. There were 360,933 breast cancer cases diagnosed 1988-2006. Chi-Square analyses and Cox proportional hazards models, to estimate relative risks for breast cancer mortality after adjusting for confounders, were performed using Statistical Analysis Software 9.2. Among Asian Indian/Pakistani breast cancer patients, 16.2% were < 40 yrs. old compared to 6.23% in Caucasians (p < 0.0001). Asian Indian women had more invasive ductal carcinoma (69.1 vs. 65.7%, p < 0.0001), inflammatory cancer (1.4% vs. 0.8, p < 0.0001) and less invasive lobular carcinoma (4.2% vs. 8.1%, p < 0.0001) than Caucasians. Asian Indian/Pakistani women had more ER/PR negative breast cancer (30.6% vs. 21.8%, p = 0.0095) than Caucasians. Adjusting for stage at diagnosis, age, tumor grade, nodal status, and histology, Asian Indian/Pakistani women's survival was similar to Caucasians, while African Americans' was worse. Asian Indian/Pakistani women have higher frequency of breast cancer (particularly in age < 40), ER/PR negative invasive ductal and inflammatory cancer than Caucasians

  8. Measurement of tumour size with mammography, sonography and magnetic resonance imaging as compared to histological tumour size in primary breast cancer

    International Nuclear Information System (INIS)

    Tumour size in breast cancer influences therapeutic decisions. The purpose of this study was to evaluate sizing of primary breast cancer using mammography, sonography and magnetic resonance imaging (MRI) and thereby establish which imaging method most accurately corresponds with the size of the histological result. Data from 121 patients with primary breast cancer were analysed in a retrospective study. The results were divided into the groups “ductal carcinoma in situ (DCIS)”, invasive ductal carcinoma (IDC) + ductal carcinoma in situ (DCIS)”, “invasive ductal carcinoma (IDC)”, “invasive lobular carcinoma (ILC)” and “other tumours” (tubular, medullary, mucinous and papillary breast cancer). The largest tumour diameter was chosen as the sizing reference in each case. Bland-Altman analysis was used to determine to what extent the imaging tumour size correlated with the histopathological tumour sizes. Tumour size was found to be significantly underestimated with sonography, especially for the tumour groups IDC + DCIS, IDC and ILC. The greatest difference between sonographic sizing and actual histological tumour size was found with invasive lobular breast cancer. There was no significant difference between mammographic and histological sizing. MRI overestimated non-significantly the tumour size and is superior to the other imaging techniques in sizing of IDC + DCIS and ILC. The histological subtype should be included in imaging interpretation for planning surgery in order to estimate the histological tumour size as accurately as possible

    To evaluate how breast cancer vascularity detected by power Doppler sonography correlates with microvessel density(MVD) and lymph node involvement. Power Doppler US was performed on 47 patients with pathologically diagnosed invasive ductal carcinoma. According to the presense or absence of vessels, power Doppler findings were categorized regarding total tumors and tumors less than 2 cm. MVD was assessed immunohistochemically using polyclonal antisera against factor VIII. Tumor vascularity was correlated with MVD and lymph node involvement. Among 47 infiltrating ductal carcinomas, 35 (74.5%) cases were vascular and 12 (25.5%) cases were avascular on power Doppler US. The mean MVD of the vascular and avascular carcinomas did not show any statistical difference. However, lymph mode involvement showed significant statistical difference between the two groups (51.4% versus 25.0%, p=0.036), even though in cancers less than 2 cm (40% versus 22.2%, p=0.047). Breast cancer vascularity detected by power Doppler sonography was not correlated with MVD but correlated with lymph node involvement. So we suggest that power Doppler sonography may be useful for predicting lymph node metastasis.

  11. Mitosis detection in breast cancer histological images An ICPR 2012 contest

    2013-01-01

    Full Text Available Introduction: In the framework of the Cognitive Microscope (MICO project, we have set up a contest about mitosis detection in images of H and E stained slides of breast cancer for the conference ICPR 2012. Mitotic count is an important parameter for the prognosis of breast cancer. However, mitosis detection in digital histopathology is a challenging problem that needs a deeper study. Indeed, mitosis detection is difficult because mitosis are small objects with a large variety of shapes, and they can thus be easily confused with some other objects or artefacts present in the image. We added a further dimension to the contest by using two different slide scanners having different resolutions and producing red-green-blue (RGB images, and a multi-spectral microscope producing images in 10 different spectral bands and 17 layers Z-stack. 17 teams participated in the study and the best team achieved a recall rate of 0.7 and precision of 0.89. Context: Several studies on automatic tools to process digitized slides have been reported focusing mainly on nuclei or tubule detection. Mitosis detection is a challenging problem that has not yet been addressed well in the literature. Aims: Mitotic count is an important parameter in breast cancer grading as it gives an evaluation of the aggressiveness of the tumor. However, consistency, reproducibility and agreement on mitotic count for the same slide can vary largely among pathologists. An automatic tool for this task may help for reaching a better consistency, and at the same time reducing the burden of this demanding task for the pathologists. Subjects and Methods: Professor Frιdιrique Capron team of the pathology department at Pitiι-Salpκtriθre Hospital in Paris, France, has selected a set of five slides of breast cancer. The slides are stained with H and E. They have been scanned by three different equipments: Aperio ScanScope XT slide scanner, Hamamatsu NanoZoomer 2.0-HT slide scanner and 10 bands

    The indication for neoadjuvant chemotherapy (NAC) has recently broadened to include its use in the treatment of initial stage breast cancer. Axillary lymph node metastasis after NAC in breast cancer is a poor prognostic factor. Thus, the prediction of lymph node metastasis is important to estimate the prognosis of breast cancer patients after NAC. Therefore, we focused on residual carcinoma patterns of primary breast tumors after NAC and examined the correlation between the patterns and lymph...

    2010-06-01

    Full Text Available It is not known whether in patients with breast cancer the occurrence of elevated serum tumour markers depends on its histological type. The aim of the study was to assess relationship between breast cancer histological type and the presence of increased serum levels of CEA and CA 15-3. The study population was 428 patients (all women, mean age 52.5 years, treated at The Department of Surgery of Wroclaw Medical University from 2005 to 2008 due to breast cancer. All of them had their preoperative CA 15-3 and CEA serum concentrations measured. According to the TNM system, 21% of patients were in stage I, 32.5% in stage II, 46.5% in stage III of the disease. In patients with ductal type of the cancer the elevated serum levels of CEA and CA 15-3 were observed in 48.7% and 42.2%, in lobular type in 42.4% and 52.5%, and in non-ductal/tubular types in 48.1% and 40.4% (p=N/S. Stepwise logistic regression analyses showed that ductal breast cancer is related to elevated CEA and normal CA 15-3 serum levels. The histological types of breast cancer are not significantly related to elevated serum levels of CEA and/or CA 15-3.

  14. Radiation therapy for brain metastases from breast cancer by histological classification

    International Nuclear Information System (INIS)

    One hundred thirteen patients with metastatic brain tumor from breast cancer who were treated with external irradiation between 1989 and 1997 at Cancer Institute Hospital were studied. The patients were all histopathologically proven to have invasive ductal carcinoma (scirrhous type 54 cases, papillotubular type 18, solid-tubular type 41). The patients were evaluated for efficacy and histopathological subtypes. The time interval between the diagnosis of breast cancer and brain metastases was 53.6 months for the scirrhous type, 75.0 months for the papillotubular type, and 35.5 months for the solid-tubular type. The time interval between the diagnosis of initial distant metastases and brain metastases was 14.3 months for the scirrhous type, 22.5 months for the papillotubular type, and 12.5 months for the solid-tubular type. Efficacy rates (CR+PR) for external irradiation of the brain metastases were 40.0% for the scirrhous type, 66.7% for the papillotubular type, and 36.6% for the solid-tubular type. The papillotubular type had a favorable efficacy rate compared with the other two types. Median survival time (MST) from the start of treatment for brain metastases and one-year survival rate were 5 months and 11.1% for the scirrhous type, 7 months and 41.5% for the papillotubular type, and 4 months and 28.3% for the solid-tubular type, respectively. No statistically significant difference between survival rates was observed among the histopathological types. Univariate analysis showed performance status, number of metastatic tumors, and existence of extracranial metastases without bony metastasis to be significantly related to prognosis. Multivariate analysis showed only extracranial metastases without bony metastases to be related to prognosis. (author)

    Breast cancers in BRCA1 gene mutation carriers often have specific histologic features: grade III tumors with pushing margins. Our purpose was to compare the mammographic and histologic features of breast cancers in carriers with those in age-matched sporadic controls. The features of breast cancers in 27 BRCA1 carriers found during annual surveillance were compared to those in 107 age-matched sporadic controls. The carriers had no (classic) spiculated mammographic lesions, a high percentage of well-defined masses and hardly any masses with microcalcifications, whereas the controls had significantly fewer well-defined ones and only in 27% spiculated lesions on the mammogram. The well-defined mammographic tumors correlated in 83% of the carriers and in 70% of the controls with histologic circumscribed tumor margins. Spiculated mammographic lesions in the controls were in 90% grade I or II tumors. DCIS with or without infiltration was seen in 22% of the carriers and in 45% of the controls. In conclusion, breast cancers diagnosed in BRCA1 carriers do not have classic malignant mammographic features. A minority of the young sporadic controls show the classic malignant lesion on the mammogram. Both carriers and controls generally show a good correlation between their mammographic- and histologic tumor pattern. (orig.)

    Full Text Available Abstract Background Some studies have indicated that reproductive factors affect the risk of histological types of breast cancer differently. The long-term protective effect of a childbirth is preceded by a short-term adverse effect. Few studies have examined whether tumors diagnosed shortly after birth have specific histological characteristics. Methods In the present register-based study, comprising information for 22,867 Norwegian breast cancer cases (20-74 years, we examined whether histological type (9 categories and grade of tumor (2 combined categories differed by parity or age at first birth. Associations with time since birth were evaluated among 9709 women diagnosed before age 50 years. Chi-square tests were applied for comparing proportions, whereas odds ratios (each histological type vs. ductal, or grade 3-4 vs. grade 1-2 were estimated in polytomous and binary logistic regression analyses. Results Ductal tumors, the most common histological type, accounted for 81.4% of all cases, followed by lobular tumors (6.3% and unspecified carcinomas (5.5%. Other subtypes accounted for 0.4%-1.5% of the cases each. For all histological types, the proportions differed significantly by age at diagnoses. The proportion of mucinous and tubular tumors decreased with increasing parity, whereas Paget disease and medullary tumors were most common in women of high parity. An increasing trend with increasing age at first birth was most pronounced for lobular tumors and unspecified carcinomas; an association in the opposite direction was seen in relation to medullary and tubular tumors. In age-adjusted analyses, only the proportions of unspecified carcinomas and lobular tumors decreased significantly with increasing time since first and last birth. However, ductal tumors, and malignant sarcomas, mainly phyllodes tumors, seemed to occur at higher frequency in women diagnosed Conclusion Our results support previous observations that reproductive factors

    Full Text Available Objective: Data on hormone receptor and Her2/neu expression in breast cancers from Saudi Arabia and Gulf Region is sparse. We undertook this study to describe the patterns of hormone receptor and Her2/neu protein expression in breast carcinoma and compared them with the histological grade at a university hospital in Riyadh.Material and Method: We conducted a retrospective hormone receptor and Her2/neu study on 164 histologically confirmed invasive ductal carcinoma of the breast between the year 2002 and 2008. Immunohistochemical analysis for estrogen receptor, progestrone receptor and Her2/neu was done in all the cases. Fluorescent in situ hybridization (FISH for Her2/neu gene amplification was performed in all 2+ cases and a few equivocal 1+ and 3+cases by immunohistochemistry. The results were then compared in a blinded fashion. Correlation between Estrogen Receptor, Progesterone Receptor and Her2/neu amplification and grade of tumour were calculated.Result: The prevalence of estrogen receptor, progestrone receptor and Her2/neu overexpression were 64.6%, 57.3% and 35.3% respectively. The expression of estrogen receptor and progestrone receptor were significantly correlated (p<0.001. There was also a significant negative correlation between expression of hormone receptor and Her2/neu amplification. The histological grade of the tumour was also significantly correlated to the expression of both estrogen receptor and progestrone receptor. However, the relationship between Her2/neu amplification and grade of tumour was not significant and many of the grade III tumours were Her2/neu negative. In addition Her2/neu gene amplification by FISH was observed in 84.6% of breast cancers that were 3+ and in 18.75% of the cases that were 2+ by immunohistochemistry.Conclusion: The revalence of estrogen receptor, progestrone receptor expression and Her2/neu amplification in breast cancers in Saudi Arabian population is similar to that reported internationally

    Purpose: To validate imaging parameters from diffusion-weighted imaging and dynamic contrast-enhanced MRI with immunohistology and to non-invasively assess microstructure of experimental breast cancer bone metastases. Materials and methods: Animals bearing breast cancer bone metastases were imaged in a clinical 1.5 T MRI scanner. HASTE sequences were performed to calculate apparent diffusion coefficients. Saturation recovery turbo FLASH sequences were conducted while infusing 0.1 mmol/l Gd–DTPA for dynamic contrast-enhanced MRI to quantify parameters amplitude A and exchange rate constant k{sub ep}. After imaging, bone metastases were analyzed immunohistologically. Results: We found correlations of the apparent diffusion coefficients from diffusion-weighted imaging with tumor cellularity as assessed with cell nuclei staining. Histological vessel maturity was correlated negatively with parameters A and k{sub ep} from dynamic contrast-enhanced MRI. Tumor size correlated inversely with cell density and vessel permeability as well as positively with mean vessel calibers. Parameters from the rim of bone metastases differed significantly from values of the center. Conclusion: In vivo diffusion-weighted imaging and dynamic contrast-enhanced MRI in experimental bone metastases provide information about tumor cellularity and vascularity and correlate well with immunohistology.

La extirpación del ganglio centinela es una técnica quirúrgica muy extendida cuyo objetivo es evitar el vaciamiento axilar en pacientes con cáncer de mama en estadios iniciales. La determinación de la infiltración tumoral puede ser evidente en caso de macrometástasis (>2mm, o difícil de detectar en las micrometástasis (2mm, 5 fueron micrometástasis Background. The extirpation of the sentinel node is a widespread surgical technique whose aim is to avoid axillary resection in patients with breast cancer at early stages. Determination of tumoral infiltration can be evident in the case of macrometastasis (>2mm, or difficult to detect in micrometastasis (2mm, 5 were micrometastases <2mm and 3 were isolated cellular groups (between 0.2 and 2mm. In 6 cases (43%, the metastases only became evident with queratine staining in serialized cuts. Axillary resection was carried out in 44 cases. Conclusions. The histological study of the sentinel nodes makes it possible to evaluate the status of tumoral infiltration of the axillary ganglions and to greatly reduce axillary lymphadenectomies. The conventional study of the sentinel node (with a single section is insufficient for the diagnosis of tumoral infiltration. In our series, histological study using a protocol of serialized sections has enabled us to detect some 43% of metastases in the sentinel node that were not evident in the initial section.

    Breast cancer is the most common malignancy among females in the world. Age and familial history are the major risk factors for the development of this disease in Iran. Mutations of BRCA1 and BRCA2 genes are associated with a greatly increased risk for development of familial breast cancer. Frequency of BRCA mutations was identified in familial breast cancers (FBC) and non-familial breast cancers (NFBC) by molecular genetics, morphological and Immunohistochemical methods. Thirty forth formalin-fixed, paraffin-embedded breast tissue tumors were analyzed from 16 patients with FBC and 18 patients with NFBC. Three 5382insC mutations detected by multiplex PCR in 16 familial breast cancers. Immunohistochemical method was used to detect estrogen receptor (ER) and progesterona receptor (PR) and TP53. Comparison of ER, PR and TP53 exhibited high difference (P < 0.0001) in familial breast cancers and non-familial breast cancers. Our results demonstrated that 5382insC mutation, ER, PR, TP53, mitotic activity, polymorphism, necrosis and tubules can serve as the major risk factors for the development of FBC. PMID:18630122

    Male breast cancer is rare, with some pathological and radiological differences from female breast cancer. There is less familiarity with the imaging appearances of male breast cancer, due to its rarity and the more variable use of preoperative imaging. This review will illustrate the commonest imaging appearances of male breast cancer, with emphasis on differences from female breast cancer and potential pitfalls in diagnosis, based on a 10 year experience in our institution.

  10. Differences in fluorescence profiles from breast cancer tissues due to changes in relative tryptophan content via energy transfer: tryptophan content correlates with histologic grade and tumor size but not with lymph node metastases

    The correlation between histologic grade, an increasingly important measure of prognosis for patients with breast cancer, and tryptophan levels from tissues of 15 breast carcinoma patients was investigated. Changes in the relative content of key native organic biomolecule tryptophan were seen from the fluorescence spectra of cancerous and paired normal tissues with excitation wavelengths of 280 and 300 nm. Due to a large spectral overlap and matching excitation-emission spectra, fluorescence resonance energy transfer from tryptophan-donor to reduced nicotinamide adenine dinucleotides-acceptor was noted. We used the ratios of fluorescence intensities at their spectral emission peaks, or spectral fingerprint peaks, at 340, 440, and 460 nm. Higher ratios correlated strongly with high histologic grade, while lower-grade tumors had low ratios. Large tumor size also correlated with high ratios, while the number of lymph node metastases, a major factor in staging, was not correlated with tryptophan levels. High histologic grade correlates strongly with increased content of tryptophan in breast cancer tissues and suggests that measurement of tryptophan content may be useful as a part of the evaluation of these patients.

    Breast cancer is the leading cause of cancer deaths in Ghanaian women.To describes the characteristics of breast cancer patients attending the Komfo Anokye Teaching Hospital in Kumasi, Ghana.The study was conducted at the Komfo Anokye Teaching Hospital. Between July 1st 2004 and June 30th 2009 patients presenting with breast lumps were assessed by clinical examination, imaging studies and pathological examination. Relevant clinical and pathological were recorded prospectively data on all patients with microscopically proven breast cancer. The cancers were graded according to the modified Bloom-Richardson system. Tissue immunoperoxidase stains for oestrogen, progesterone receptors and c-erb2 oncogene were performed with commercially prepared antigens and reagents.Nineteen thousand four hundred and twenty – three (19,423) patients were seen during the study period. There were 330 (1.7%) patients with histologically proven breast cancer. The mean age was 49.1 years. A palpable breast lump was detected in 248 patients (75.2%). Two hundred and eighty –one patients (85.2%) presented with Stages III and IV , 271 (82.1%) invasive and 230 ( 85.2%) high grade carcinomas. Oestrogen and progesterone receptors were positive in 32 and 9 cases respectively. Her2 protein was positive in 11 cases. In Kumasi, as in other parts of Ghana, breast cancer affects mostly young pre-menopausal who present with advanced disease. The cancers have unfavourable prognostic features and are unlikely to respond to hormonal therapy. (au)

  13. The use of 99m-Tc-labelled neutral liposomes in lymphoscintigraphy: a comparison of scintigram interpretations with node histology in a series of breast cancer patients

    International Nuclear Information System (INIS)

    During studies of the possible tumour localization of 99m-Tc labelled liposomes following systemic administration, a small quantity of the labelled material became extravasated and was subsequently seen to be localized in the lymph node chain draining the region. This observation led to the initial description of labelled liposomes for lymph node imaging and their application to the preoperative staging of breast cancer; these initial studies were carried out at Charing Cross Hospital by Osborne, Burn, Richardson, Ryman, Jewkes and Jeyasingh. This paper presents further results of a pilot study on patients with breast cancer which indicate that auxillary lymphoscintigraphy gives valuable information about the function of the regional lymph nodes in breast cancer. The presence of lymph node metastases can be detected and the procedure may act as an in vivo test of macrophage function. (Auth.)

    Objective: This study was performed to exam the relativeship between mammographic calcifications and breast cancer. Methods: All of the 184 patients with breast diseases underwent mammography before either an open biopsy or a mastectomy. The presence,morphology, and distribution of calcifications visualized on mammograms for breast cancer were compared with the controls who remained cancer free. Statistical comparisons were made by using the x2 test. Results:Of the 184 patients with breast diaeases, 93 malignant and 91 benign lesions were histologically confirmed.Calcifications were visualized on mammograms in 60(64%) of 93 breast cancers and 26 (28%) of 91 non breast cancers. The estimated odds ratio (OR) of breast cancer was 4.5 in women with calcifications seen on mammograms, compared with those having none (P<0.01). Of the 60 breast carcinomas having mammographic calcifications, 28 (47%) were infiltrating ductal carcinomas.There were only 8 (24%) cases with infiltrating ductal cancers in the group of without calcifications seen on the mammograms (P<0.05). Conclusion: Our finding suggests that mammographic calcification appears to be a risk factor for breast cancer. The granular and linear cast type calcification provide clues to the presence of breast cancer, especially when the carcinomas without associated masses were seen on mammograms.

    Breast cancer is a leading cause of cancer-related deaths in women worldwide. Although tumorectomy, radiotherapy, chemotherapy and hormone replacement therapy have been used for the treatment of breast cancer, there is no effective therapy for patients with invasive and metastatic breast cancer. Immunotherapy may be proved effective in treating patients with advanced breast cancer. Breast cancer immunotherapy includes antibody based immunotherapy, cancer vaccine immunotherapy, adoptive T cell transfer immunotherapy and T cell receptor gene transfer immunotherapy. Antibody based immunotherapy such as the monoclonal antibody against HER-2/neu (trastuzumab) is successfully used in the treatment of breast cancer patients with over-expressed HER-2/neu, however, HER-2/neu is over-expressed only in 25-30% of breast cancer patients. Cancer vaccine immunotherapy is a promising method to treat cancer patients. Cancer vaccines can be used to induce specific anti-tumor immunity in breast cancer patients, but cannot induce objective tumor regression. Adoptive T cell transfer immunotherapy is an effective method in the treatment of melanoma patients. Recent advances in anti-tumor T cell generation ex vivo and limited clinical trial data have made the feasibility of adoptive T cell transfer immunotherapy in the treatment of breast cancer patients. T cell receptor gene transfer can redirect the specificity of T cells. Chimeric receptor, scFv(anti-HER-2/neu)/zeta receptor, was successfully used to redirect cytotoxic T lymphocyte hybridoma cells to obtain anti-HER-2/neu positive tumor cells, suggesting the feasibility of treatment of breast cancer patients with T cell receptor gene transfer immunotherapy. Clinical trials will approve that immunotherapy is an effective method to cure breast cancer disease in the near future. Cellular & Molecular Immunology.

  3. Early breast cancer

    International Nuclear Information System (INIS)

    Breast cancer remains a common disease throughout the world. Here we review new knowledge about early breast cancer obtained during the past 5 years. The prognosis of early breast cancer is generally favorable. Especially, ductal carcinoma in situ has been regarded as a non-life-threatening disease. Therefore, early diagnosis and early onset of the treatment has been important. Early age at menarche, late age at first birth, and late age at menopause are related to breast cancer risk. Examination by mammography and ultrasonography is still the most effective means of detection for premenopausal and postmenopausal women, respectively. Additionally, there have been important advances in MRI, sentinel lymph node biopsy, breast-conserving surgery, partial breast irradiation, neoadjuvant systemic therapy, and adjuvant systemic therapy. Another approach to keeping the disease under control is the elucidation of breast cancer's molecular biological features. Assessment of potential molecular targets can lead to early diagnosis and molecular targeted treatment. (author)

METHODS: Incident breast cancer cases in Danish women (n = 49,312; 1995 to 2008...... Cox regression models. RESULTS: At diagnosis, tumors in digoxin users were more likely ER+ (85.4% vs. 78.6%: P = 0.002) and have grade 1 ductal histology (37.2% vs. 25.7%; P = 0.004), compared to non-users. 45 relapses occurred in women already using digoxin at breast cancer diagnosis (1,487 person...... cancers arising in digoxin-using women had better prognostic features. After adjustment for markers, overall breast cancer relapse risk in digoxin users was not increased significantly, although recurrence hazards for ER+ tumors were higher in the first year following diagnosis....

    The effectiveness of film mammography is a source of concern to radiologists because neither the ribs nor retromammary space is included on the films in good quality examinations. One hundred seven incident cancers were detected in 10,034 self-referred women followed at the University of Michigan Breast Cancer Detection Demonstration Project (UM-BCDDP) for 5 years. These cancers were analyzed for location on the film, method of detection, size, histology, and the number of films required for detection. Mammography alone detected 52 (49%) of the cancers, whereas physical examination alone detected 15 (14%). The other 40 cancers were detectable on both examinations. All of the 92 cancers detected by mammography were visible in both the mediolateral and the craniocaudal views. Mammography consistently detected cancer in the breast, regardless of tumor size, histologic type, or location within the breast

  16. Contralateral breast cancer risk

    International Nuclear Information System (INIS)

    The use of breast-conserving treatment approaches for breast cancer has now become a standard option for early stage disease. Numerous randomized studies have shown medical equivalence when mastectomy is compared to lumpectomy followed by radiotherapy for the local management of this common problem. With an increased emphasis on patient involvement in the therapeutic decision making process, it is important to identify and quantify any unforeseen risks of the conservation approach. One concern that has been raised is the question of radiation- related contralateral breast cancer after breast radiotherapy. Although most studies do not show statistically significant evidence that patients treated with breast radiotherapy are at increased risk of developing contralateral breast cancer when compared to control groups treated with mastectomy alone, there are clear data showing the amount of scattered radiation absorbed by the contralateral breast during a routine course of breast radiotherapy is considerable (several Gy) and is therefore within the range where one might be concerned about radiogenic contralateral tumors. While radiation related risks of contralateral breast cancer appear to be small enough to be statistically insignificant for the majority of patients, there may exist a smaller subset which, for genetic or environmental reasons, is at special risk for scatter related second tumors. If such a group could be predicted, it would seem appropriate to offer either special counselling or special prevention procedures aimed at mitigating this second tumor risk. The use of genetic testing, detailed analysis of breast cancer family history, and the identification of patients who acquired their first breast cancer at a very early age may all be candidate screening procedures useful in identifying such at- risk groups. Since some risk mitigation strategies are convenient and easy to utilize, it makes sense to follow the classic 'ALARA' (as low as reasonably

    Expression of proliferating cell nuclear antigen (PCNA) has been shown to be of prognostic value in patients with certain types of cancer. The aim of this study was to determine if the abundance of PCNA is inversely correlated with survival of patients with breast cancer. Paraffin blocks were available from 68 patients, all of whom had been followed clinically for at least 5 years. Sections from 20 patients showed no reactivity to PCNA and were excluded from the study because it was not possible to distinguish between true negatives and false negatives (those due to poor fixation of the original specimens). The PCNA index (the number of stained cancer cells as a percentage of the total number of cancer cells present) was calculated for the remaining 48 patients. Results were analysed by Wilcoxon's rank sum test (two tailed) and Pearson's correlation coefficient. There was no statistical difference between the PCNA indices of those patients dead from their disease within 5 years of diagnosis compared with those alive and without signs of breast cancer at 5 years. There was also no correlation between PCNA index and size of the cancer, involvement of axillary lymph nodes, time to recurrence or time to death. There was, however, a significant correlation between PCNA index and histological grade (P = 0.029). It appears that PCNA staining of stored paraffin sections is of little prognostic value in patients with breast cancer. PMID:8101708

    Male breast cancer, which represents only 1% of all breast cancers, is occasionally associated with a family history of breast cancer. Sporadic male breast cancers presenting with another primary breast cancer are extremely rare. In this article, we report on a 70-year-old male patient with bilateral multifocal and synchronous breast cancer and without a family history of breast cancer.

    Full Text Available Cancer metastasis, resistance to therapies and disease recurrence are significant hurdles to successful treatment of breast cancer. Identifying mechanisms by which cancer spreads, survives treatment regimes and regenerates more aggressive tumours are critical to improving patient survival. Substantial evidence gathered over the last 10 years suggests that breast cancer progression and recurrence is supported by cancer stem cells (CSCs. Understanding how CSCs form and how they contribute to the pathology of breast cancer will greatly aid the pursuit of novel therapies targeted at eliminating these cells. This review will summarise what is currently known about the origins of breast CSCs, their role in disease progression and ways in which they may be targeted therapeutically.

    Full Text Available This paper introduces a computer-assisted diagnosis (CAD system for automatic mitosis detection from breast cancer histopathology slide images. In this system, a new approach for reducing the number of false positives is proposed based on Teaching-Learning-Based optimization (TLBO. The proposed CAD system is implemented on the histopathology slide images acquired by Aperio XT scanner (scanner A. In TLBO algorithm, the number of false positives (falsely detected nonmitosis candidates as mitosis ones is defined as a cost function and, by minimizing it, many of nonmitosis candidates will be removed. Then some color and texture (textural features such as those derived from cooccurrence and run-length matrices are extracted from the remaining candidates and finally mitotic cells are classified using a specific support vector machine (SVM classifier. The simulation results have proven the claims about the high performance and efficiency of the proposed CAD system.

  5. Prognostic factors of breast cancer

    International Nuclear Information System (INIS)

    The prognostic factors must to be differentiated of the predictive ones. A prognostic factor is any measurement used at moment of the surgery correlated with the free interval of disease or global survival in the absence of the systemic adjuvant treatment and as result is able to correlate with the natural history of the disease. In contrast, a predictive factor is any measurement associated with the response to a given treatment. Among the prognostic factors of the breast cancer are included the clinical, histological, biological, genetic and psychosocial factors. In present review of psychosocial prognostic factors has been demonstrated that the stress and the depression are negative prognostic factors in patients presenting with breast cancer. It is essential to remember that the assessment of just one prognostic parameter is a help but it is not useful to clinical and therapeutic management of the patient.(author)

  6. Pregnancy After Breast Cancer.

    Gemignani; Petrek

    1999-05-01

    BACKGROUND: The issue of pregnancy following the diagnosis and treatment of breast cancer is important because the incidence of breast cancer is increasing in women of childbearing age. The fact that many women are delaying childbearing, whether for educational, professional, or personal reasons, increases the number of women who will undergo breast cancer treatment before completing childbearing. METHODS: Data on pregnancy in breast cancer survivors are limited and consist only of retrospective data. This paper reviews the published literature on the influence of subsequent pregnancy on breast cancer, including three recent large-scale population-based studies. RESULTS: The survival of women with breast carcinoma who subsequently become pregnant is not reported to be decreased in any of the published series. However, several biases may be present that justify the concern regarding the conclusions. CONCLUSIONS: Further research on the safety of subsequent pregnancy after breast carcinoma treatment is needed. To address these issues, patients are currently being accrued for a large, prospective, multicenter study of young breast carcinoma patients. PMID:10758557

    We investigated the relationship between methylxanthine consumption and breast cancer using data from a case-control study which included 1,510 cases and 1,882 controls identified through a nation-wide breast cancer screening program. There was no evidence of a positive association between methylxanthine consumption and risk of breast cancer. In fact, there was some suggestion of a negative association, particularly in women diagnosed after age 50. In addition, there was no evidence of increased risk with past or recent methylxanthine consumption, or with the consumption of caffeine or specific beverages, most notably brewed or instant caffeinated coffee and tea.

    Background p73, a homologue of p53, has been located at chromosome 1 p36-33, a region of frequently observed loss of heterozygosity in breast cancers. The objective of the present study was to investigate the function of p73 in Japanese with breast cancers. Methods Sixty Japanese patients with breast cancer were assessed by polymerase chain reaction single strand confirmation polymorphism analysis and direct sequencing to detect the p73 allele. p73 mRNA levels were also determined in 40 out of 60 patients by reverse-transcriptional polymerase chain reaction. Results We analyzed the entire open reading frame of the p73 gene by polymerase chain reaction single strand confirmation polymorphism and sequencing, and failed to identify any mutations of p73 in the encoding regions detected.Loss of heterozygosity of p73 was infrequent and only found in 9% of breast carcinomas. We revealed a few polymorphisms with a frequency of 13%-29%, which had been reported previously. Down-regulation of p73 mRNA expression was observed in tumor tissues in comparison to the normal breast tissues. A significant inverse correlation was found between p73 transcripts and high histological grade, suggesting that down-regulated p73 expression could be related to poor prognosis in those patients. Conclusion Our results suggest that p73 may serve as a tumor suppressor gene and its expression plays a role in tumorigenesis in Japanese patients with breast cancer.

  11. Early breast cancer

    International Nuclear Information System (INIS)

    The therapy of early breast cancer has been changing during the last decennium. It requires a multi-disciplinary approach and in each of these disciplines improvements have been implemented. The result is that treatment schedules can now be adapted to specific subgroups. In this review early breast cancer is defined as operable disease, using the criteria set out by Haagensen. Emphasis is given to describing the new developments in prognostic criteria, since these form the basis for creating subgroups for specific treatment schedules. Distinction is made between the factors relating to growth rate and those relating to metastatic potential. Data on screening promises a beneficial effect of the implementation of screening in national health care programs. Important shifts are seen in treatment schedules; the place of postoperative radiotherapy after classic ablative treatment is being challenged, whereas it plays a major role in the new breast conserving therapy schedules. The data mentioned in the review suggest that a large proportion of 'operable' cases can be treated with breast conservation but details in the technique of breast conserving therapy are still under investigation. They form a major part of the coming prospective studies in breast cancer. Improvements in reconstruction techniques, creating better cosmetic results, make reconstruction more competitive with breast conserving therapy. The use of chemotherapy and endocrine manipulation in early breast cancer has now been clearly confirmed by the overview technique by the Peto-group, thanks to all efforts of individual trialists together.

    BACKGROUND: In parous women preeclampsia has been associated with reduced risk of developing breast cancer. Characteristics of births following preeclamptic pregnancies may help understand mechanisms involved in the breast cancer risk reduction inferred by preeclampsia. METHODS: We conducted...... a register-based cohort study of all Danish women giving birth during 1978-2010 (n = 778,701). The association between preeclampsia and breast cancer was evaluated overall and according to birth characteristics by means of incidence rate ratios (IRR) estimated in Poisson regression models. RESULTS: Compared...... with women with non-preeclamptic pregnancies only, women with one or more preeclamptic pregnancies were 19% significantly less likely to develop breast cancer (IRR = 0.81 [95% CI 0.72-0.93]).

  2. Radiologic aspects of breast cancers detected through a breast cancer screening program

    International Nuclear Information System (INIS)

    Early detection in breast cancer and reduced mortality in women with this disease is today attributed to widespread use of mammography. High-quality performance is essential in all steps of breast cancer screening programs in order to avoid unnecessary anxiety and surgery in the women concerned. This report presents radiologic aspects of screening cancers. A total of 8370 asymptomatic women aged 50-69 years were screened with 2-view mammography, of which only 70 (0.84 percent) were selected for surgery after a thorough work-up. Cancers were verified histologically in 61 women and 9 showed non-malignant histology, giving a cancer detection rate of 7.3 cancers per thousand screened asymptomatic women. The benign/malignant ratio in the operated cases is thus approximately 1:7. The cancers detected showed all existing types of mammographic features where 77 percent (47 cases) showed rather typical findings, such as spiculated densities both with and without microcalcifications. The results indicate that surgery can be minimized without impairing the breast cancer detection rate. Radiologists in screening programs should be aware that a large proportion of non-palpable breast cancers present in rather unconventional forms. This point is important in order to maintain a high cancer detection rate and thereby justify the widespread use of mammography as a screening tool for breast cancer in asymptomatic women.

    Background Many researches suggested that obesity increased the risk of breast cancer, but the mechanism was currently unknown. Adipocytokines might mediate the relationship. Our study was aimed to investigate the relationship between serum levels of resistin, adiponectin and leptin and the onset, invasion and metastasis of breast cancer.Methods Blood samples were collected from 80 newly diagnosed, histologically confirmed breast cancer patients and 50 age-matched healthy controls. Serum levels of resistin, adiponectin and leptin were determined by enzyme-linked immunosorbent assays (ELISA); fasting blood glucose (FBG), lipids, body mass index (BMI), and waist circumference (WC) were assayed simultaneously.Results Serum levels of adiponectin ((8.60±2.92) mg/L vs (10.37±2.81) mg/L, P=0.001) and HDL-c were significantly decreased in breast cancer patients in comparison to controls. Serum levels of resistin ((26.35±5.36) μg/L vs (23.32±4.75)μg/L, P=0.000), leptin ((1.35±0.42) μg/L vs (1.06±0.39) μg/L, P=0.003), FBG and triglyceride (TG) in breast cancer patients were increased in contrast to controls, respectively. However, we did not find the significant difference of the serum levels of resistin, adiponectin and leptin between premenopausal breast cancer patients and healthy controls (P=0.091, 0.109 and 0.084, respectively). The serum levels of resistin, adiponectin and leptin were significantly different between patients with lymph node metastasis (LNM) and those without LNM (P=0.001, 0.000 and 0.006, respectively).The stepwise regression analysis indicated that the tumor size had the close correlation with leptin (R2=0.414, P=0.000)and FBG (R2=0.602, P=0.000). Logistic regression analysis showed that reduced serum levels of adiponectin (OR:0.805;95%CI: 0.704-0.921; P=0.001), HDL (OR: 0.087; 95%CI: 0.011-0.691, P=0.021), elevated leptin (OR:2.235;95%CI:1.898-4.526; P=0.004) and resistin (OR: 1.335; 95%CI: 1.114-2.354; P=0.012) increased the risk for

Triple negative breast cancer (TNBC is a recently identified biological variant with aggressive tumor behavior and poor prognosis. Data of hormonal status from the Indian population is scarce due to financial constraints in performing immunohistochemistry evaluation. The present study aims to prospectively analyze receptor status of all breast cancer patients and identify TNBC and compare their clinical profile and short term survival with other non-TNBC group. Materials and methods: All cytologically and histopathologically confirmed cases of carcinoma breast were prospectively enrolled. In a longitudinal study at tertiary care hospital in central India based on the hormonal status, they were further divided into TNBC and other groups. Comparison of risk factors, clinical profile and short-term survival was carried out. Results: A total 85 patients were enrolled and of them 37 (43.7% were TNBC. On comparing risk factors ie, age, age at menarche, total reproductive age, age at first child birth, and menopausal status – no statistical significance was observed between the TNBC and non-TNBC groups. But on comparison of clinical profile TNBC tumors were significantly large with majority of patients presenting as locally advanced breast cancer (83%. No statistical difference was observed in axillary lymph node status between two groups. TNBC tumors were histologically more aggressive (grade 3 compared to other groups. No statistically significant difference was observed in short term overall survival but all three deaths were observed in the TNBC group only and two local recurrences after surgery were observed in the TNBC group. Conclusion: TNBC forms a large proportion of carcinoma breast patients in a central

    The BioScan System was developed by OmniCorder Technologies, Inc. at the Jet Propulsion Laboratory. The system is able to locate cancerous lesions by detecting the cancer's ability to recruit a new blood supply. A digital sensor detects infrared energy emitted from the body and identifies the minute differences accompanying the blood flow changes associated with cancerous cells. It also has potential use as a monitoring device during cancer treatment. This technology will reduce the time taken to detect cancerous cells and allow for earlier intervention, therefore increasing the overall survival rates of breast cancer patients.

    Full Text Available Trials with tamoxifen have clearly shown that the risk of developing oestrogen receptor positive breast cancer can be reduced by at least 50% with prophylactic agents. The current challenge is to find new agents which achieve this or better efficacy, but with fewer side effects. Recent results indicate that the SERM raloxifene has similar efficacy to tamoxifen, but leads to fewer endometrial cancers, gynecological symptoms, and thromboembolic events. Results for contralateral tumors in adjuvant trials suggest that aromatase inhibitors may be able to prevent up to 70%–80% of ER-positive breast cancers, and this is currently being investigated in two large prevention trials, one using anastrozole (IBIS-II and the other exemestane (MAP.3.

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

  16. Genetic factors and breast cancer laterality

    International Nuclear Information System (INIS)

    Women are more likely to develop cancer in the left breast than the right. Such laterality may influence subsequent management, especially in elderly patients with heart disease who may require radiation therapy. The purpose of this study was to explore possible factors for such cancer laterality. In this work, clinical data for consecutive patients with histologically confirmed breast cancer were reviewed, with emphasis on clinical presentation and family history. Between 2005 and 2012, 687 patients with breast cancer were seen. Two women with incomplete data and eleven men were excluded. In total, 343 (50.9%) patients presented with left breast cancer, 311 (46.1%) with right breast cancer, and 20 (3.0%) with simultaneous bilateral malignancy. There were no significant differences between the three groups, especially in regards to clinical presentation and tumor characteristics. A total of 622 (92.3%) patients had unilateral primary, 20 (3.0%) had simultaneous bilateral, and 32 (4.7%) had metachronous primary breast cancer with subsequent contralateral breast cancer after 7.5–236 months. The worst 10-year survival was for bilateral simultaneous (18%) compared with unilateral (28%) and metachronous primaries (90%). There were no differences in survival in relation to breast cancer laterality, handedness, and presence or absence of a family history of cancer. There were significant similarities between patients and first-degree relatives in regards to breast cancer laterality, namely same breast (30/66, 45.5%), opposite breast (9/66, 13.6%), and bilateral cancer (27/66, 40.9, P=0.01163). This was more evident among patients and their sisters (17/32, 53.1%) or mothers (11/27, 40.7%, P=0.0689). There were also close similarities in relation to age at initial diagnosis of cancer for patients and their first-degree relatives for age differences of ≤5 years (48/166, 28.9%), 6–10 years (34/166, 20.5%), and >11 years (84/166, 50.6%, P=0.12065).

    Consensus is still lacking on guidelines for breast-cancer screening with mammography: who should be screened, how frequently at what age, to what benefits and at what risks. American, Dutch, Swedish and Italian studies spanning the 1960s to the 1980s reveal a benefit from screening (reduced mortality from breast cancer) that occurs unambiguously only in women 50 years of age and over. Physicians who choose to screen mammographically their over-49-year-old female patients must do so with the ...

  19. Inheritance of proliferative breast disease in breast cancer kindreds

    International Nuclear Information System (INIS)

    Previous studies have emphasized that genetic susceptibility to breast cancer is rare and is expressed primarily as premenopausal breast cancer, bilateral breast cancer, or both. Proliferative breast disease (PBD) is a significant risk factor for the development of breast cancer and appears to be a precursor lesion. PBD and breast cancer were studied in 103 women from 20 kindreds that were selected for the presence of two first degree relatives with breast cancer and in 31 control women. Physical examination, screening mammography, and four-quadrant fine-needle breast aspirates were performed. Cytologic analysis of breast aspirates revealed PBD in 35% of clinically normal female first degree relatives of breast cancer cases and in 13% of controls. Genetic analysis suggests that genetic susceptibility causes both PBD and breast cancer in these kindreds. This study supports the hypothesis that this susceptibility is responsible for a considerable portion of breast cancer, including unilateral and postmenopausal breast cancer

    Breast Cancer, with a life-time prevalence of about 10-12%, is the most common cancer in women. In 2013, the actress Angelina Jolie, by announcing she had a double mastectomy, increased the awareness of a family history of breast and ovarian cancer and the treatment available to reduce the inherited risks. In Germany, each year about 25 out of 100,000 women (age-standardized according to European Standard) die of the disease. The number of newly diagnosed cases is about 72,000 per year. In comparison, many other countries record higher levels. Investing in the development of new therapies has therefore been key for many years. Prevention programs, such as the mammography screening are publicly touted, in both cases with the aim to reduce breast cancer mortality. To accurately assess the risk in underwriting, it is important to know about the risk factors for the development of breast cancer, as well as the latest advances in prevention, therapy and their prognostic classification. The following article provides an overview. PMID:25000626

  2. SPECT imaging for breast cancer staging

    International Nuclear Information System (INIS)

    Accurate staging in breast cancer, including tumour sizing and the assessment of nodal and distant metastases, is required in order to plan surgery and post-operative therapy. Medical imaging techniques have made an important contribution to the diagnosis of carcinoma of the breast and the evaluation of local, regional and distant metastases. The study is aimed at establishing certain aspects of the diagnostic importance and priority of single photon emission computed tomography (SPECT) imaging in breast cancer. SPECT was carried out just after planar scintigraphy and then after intravenous injection of different radiopharmaceuticals in 45 women with histologically confirmed post-operation breast cancer. In 21 patients under loco-regional control of the disease before and/or after surgery, planar mammoscintigraphy and SPECT were conducted after intravenous injection of 99Tcm-MIBI (methoxyisobutyl isonitrile) or 99Tcm-anti-CEA (carcinoembryonic antigen) monoclonal antibody (MoAb). Bone SPECT was carried out in 24 patients when whole body scintigraphy was unable to determine the exact localization of bone metastatic lesions in the skull, thorax and pelvis. The results suggest that SPECT with 99Tcm-MIBI and 99Tcm-anti-CEA MoAb has high sensitivity and improves the results of conventional planar scintigraphy for breast cancer detection. Breast SPECT is a preferable method for tumour and lymph node imaging because of the excellent separation of the deep breast structures from the myocardium in the left breast and of the right breast from the liver, thus improving the resolution of small, deep seated lesions. SPECT improves breast cancer staging, and determines the tumour, nodule and metastasis categories, which are important for the treatment strategy and prognosis of the disease.

  10. Progestins and breast cancer.

    Science.gov (United States)

    Pasqualini, Jorge R

    2007-10-01

    Progestins exert their progestational activity by binding to the progesterone receptor (form A, the most active and form B, the less active) and may also interact with other steroid receptors (androgen, glucocorticoid, mineralocorticoid, estrogen). They can have important effects in other tissues besides the endometrium, including the breast, liver, bone and brain. The biological responses of progestins cover a very large domain: lipids, carbohydrates, proteins, water and electrolyte regulation, hemostasis, fibrinolysis, and cardiovascular and immunological systems. At present, more than 200 progestin compounds have been synthesized, but the biological response could be different from one to another depending on their structure, metabolism, receptor affinity, experimental conditions, target tissue or cell line, as well as the biological response considered. There is substantial evidence that mammary cancer tissue contains all the enzymes responsible for the local biosynthesis of estradiol (E(2)) from circulating precursors. Two principal pathways are implicated in the final steps of E(2) formation in breast cancer tissue: the 'aromatase pathway', which transforms androgens into estrogens, and the 'sulfatase pathway', which converts estrone sulfate (E(1)S) into estrone (E(1)) via estrone sulfatase. The final step is the conversion of weak E(1) to the potent biologically active E(2) via reductive 17beta-hydroxysteroid dehydrogenase type 1 activity. It is also well established that steroid sulfotransferases, which convert estrogens into their sulfates, are present in breast cancer tissues. It has been demonstrated that various progestins (e.g. nomegestrol acetate, medrogestone, promegestone) as well as tibolone and their metabolites can block the enzymes involved in E(2) bioformation (sulfatase, 17beta-hydroxysteroid dehydrogenase) in breast cancer cells. These substances can also stimulate the sulfotransferase activity which converts estrogens into the biologically

    Since several studies have demonstrated the inadequate diagnostic performance of mammography in high risk women, over the past two decades, different breast imaging tests have been evaluated as additional diagnostic methods to mammography, and the most relevant ones are the techniques that do not imply the use of X-rays, considering the young age of these patients and the higher radio-sensitivity. Breast dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has risen growing interest not only because of the absence of use of X-rays, but also because it provides morpho-functional features, which may depict biological characteristics of breast tissues, including invasive and in situ cancers. Different multicenter non-randomized prospective studies aimed to evaluate breast DCE-MRI as an integral part of surveillance programs, agreed about the evidence that in high risk women screening with DCE-MRI is more effective than either mammography and/or ultrasound. Moreover, this modality leads to the identifications of cancers at a more favorable stage, allowing a real advantage in terms of tumor size and nodal involvement. The medical community is evaluating to suggest DCE-MRI alone as screening modality in high-risk women, as it was reported that in these cases the sensitivity of MRI plus conventional imaging was not significantly higher than that of MRI alone. Breast MRI is now recommended as part of screening program for high risk women by both European and American guidelines. PMID:26924173

The relationship of these breast cancer cases to A-bomb radiation was sought, and in studying 5-year survival, the following conclusions were obtained concerning its relationship to histopathological findings: 1) The prognosis of the 50+ rad high dose group is the best, followed by the nonexposed group and the low dose group; 2) The apparently better survival may be due, at least in part, to the fact that this group is heavily weighted in favor of those who were younger at the time of the bomb; 3) There is no specificity of the histologic type of breast cancer in the survivors by dose; 4) Nor, is any significant difference observed in the distribution of tumor size and histological grade; 5) Cellular reaction is significantly marked at the stroma of carcinoma tissue in the high dose group; 6) Immune reaction is considered to be strong at the affected site of breast cancer in the high dose group and this can be regarded as a finding suggestive of good prognosis; 7) Further extended studies are therefore warranted.

    Presence of estrogen receptors in breast tumors allows to judge about sensitivity of cancer to hormone therapy and diseases prognosis. Objective of the study is to compare histological forms of patient's age and various estrogen receptors combination in breast cancer. 30 patients were undergone to immune-histo-chemical examination of breast tumors in the Semipalatinsk cancer clinic. According to expression of estrogen and testosteron receptors they were divided into 4 groups. The most wide-spread histologic type of cancer was dust-infiltrative. This type took place of 3.3 % for the first group, 9.9 % for the second group, 16-6 % for the third one, and 36.6 % for the fourth one. Histological type of cancer had not effects on expression of receptors estrogen and progesterone in tumor. Rare breast cancer types like medullary occurred only in the fourth group. Dividing breast cancer into positive and negative or with expression of one hormone depending on expression of estrogen, testosteron receptors may be regarded as a sensible way. More expanded examination on immune-histo-chemical markers allows extending topics regarding therapy of breast cancer. (author)

    Histologic grade is one of the most important microscopic features used to predict the prognosis of invasive breast cancer and may serve as a marker for studying cancer driving genomic abnormalities in vivo. We analyzed whole genome sequencing data from 680 cases of TCGA invasive ductal carcinomas of the breast and correlated them to corresponding pathology information. Ten genetic abnormalities were found to be statistically associated with histologic grade, including three most prevalent cancer driver events, TP53 and PIK3CA mutations and MYC amplification. A distinct genetic interaction among these genomic abnormalities was revealed as measured by the histologic grading score. While TP53 mutation and MYC amplification were synergistic in promoting tumor progression, PIK3CA mutation was found to have alleviated the oncogenic effect of either the TP53 mutation or MYC amplification, and was associated with a significant reduction in mitotic activity in TP53 mutated and/or MYC amplified breast cancer. Furthermore, we discovered that different types of genetic abnormalities (mutation versus amplification) within the same cancer driver gene (PIK3CA or GATA3) were associated with opposite histologic changes in invasive breast cancer. In conclusion, our study suggests that histologic grade may serve as a biomarker to define cancer driving genetic events in vivo. PMID:27283966

    1997-01-01

    Full Text Available In this review, we summarize the epidemiologic evidence for the associations of oral contraceptives and postmenopausal hormones with risk of breast cancer. We also describe the biologic plausibility of these relationships. Overall, there appears to be little, if any, increase in risk with oral contraceptive use in general, even among users for 10 or more years. However, compared to never users, current oral contraceptive users appear to have a modest elevation in risk that subsides within about 10 years after cessation of use. For postmenopausal hormones, the weight of the evidence suggests little or no increase in risk among users of short duration, or for use in the past. However, current longer term use is associated with an increased risk of breast cancer that increases with duration. This increase in risk is large enough, and well enough supported, to be considered along with the other risks and benefits of postmenopausal hormone therapy.

  9. Correlation between Duffy blood group phenotype and breast cancer incidence

    International Nuclear Information System (INIS)

    Different ethnicities have different distribution of Duffy blood group (DBG) phenotypes and different breast cancer morbidity. A study in our lab demonstrated that Duffy antigen/receptor for chemokines (DARC, also known as DBGP, the Duffy protein phenotype), led to the inhibition of tumorigenesis. Therefore, we tested the hypothesis that DBGP is correlated with breast cancer occurrence. DBGP proteins were examined by indirect antiglobulin testing with anti-FYa and anti-FYb antibodies. The phenotypes were classified into four groups according to the agglutination reactions: FYa + FYb+, FYa + FYb-, FYa-FYb + and FYa-FYb-. The phenotypes and pathological diagnosis of consecutively hospitalized female patients (n = 5,022) suffering from breast cancer at the Shanghai Cancer Hospital and Henan Province Cancer Hospital were investigated. The relationships between DBGP expression with breast cancer occurrence, axillary lymph status, histological subtype, tumor size pathological grade and overall survival were analyzed. The incidence of breast cancer was significantly different between FYa + FYb + (29.8%), FYa + FYb- (33.2%), FYa-FYb + (45.6%) and FYa-FYb- (59.1%; P = 0.001). Significant different numbers of breast cancer patients had metastases to the axillary lymph nodes in the FYa + FYb + group (25.1%), FYa + FYb- (36.9%), FYa-FYb + (41.0%) and FYa-FYb- (50.0%, (P = 0.005). There was a statistical significance (p = 0.022) of the overall survival difference between patients with difference phenotypes. No significant difference was observed in cancer size (t-test, p > 0.05), histological cancer type (Fisher's exact test, p > 0.05) or histological grade (Fisher's exact test, p > 0.05) between every each DBGP group.

    Full Text Available Abstract Background Different ethnicities have different distribution of Duffy blood group (DBG phenotypes and different breast cancer morbidity. A study in our lab demonstrated that Duffy antigen/receptor for chemokines (DARC, also known as DBGP, the Duffy protein phenotype, led to the inhibition of tumorigenesis. Therefore, we tested the hypothesis that DBGP is correlated with breast cancer occurrence. Methods DBGP proteins were examined by indirect antiglobulin testing with anti-FYa and anti-FYb antibodies. The phenotypes were classified into four groups according to the agglutination reactions: FYa + FYb+, FYa + FYb-, FYa-FYb + and FYa-FYb-. The phenotypes and pathological diagnosis of consecutively hospitalized female patients (n = 5,022 suffering from breast cancer at the Shanghai Cancer Hospital and Henan Province Cancer Hospital were investigated. The relationships between DBGP expression with breast cancer occurrence, axillary lymph status, histological subtype, tumor size pathological grade and overall survival were analyzed. Results The incidence of breast cancer was significantly different between FYa + FYb + (29.8%, FYa + FYb- (33.2%, FYa-FYb + (45.6% and FYa-FYb- (59.1%; P = 0.001. Significant different numbers of breast cancer patients had metastases to the axillary lymph nodes in the FYa + FYb + group (25.1%, FYa + FYb- (36.9%, FYa-FYb + (41.0% and FYa-FYb- (50.0%, (P = 0.005. There was a statistical significance (p = 0.022 of the overall survival difference between patients with difference phenotypes. No significant difference was observed in cancer size (t-test, p > 0.05, histological cancer type (Fisher's exact test, p > 0.05 or histological grade (Fisher's exact test, p > 0.05 between every each DBGP group. Conclusions DBGP is correlated with breast cancer incidence and axillary lymph node metastasis and overall survival. Further investigations are required to determine the underlying mechanism of Duffy blood group phenotype

    Being a significant health problem that affects patients in various age groups, breast cancer has been extensively studied to date. Recently, molecular breast cancer classification has advanced significantly with the availability of genomic profiling technologies. Proteomic technologies have also advanced from traditional protein assays including enzyme-linked immunosorbent assay, immunoblotting and immunohistochemistry to more comprehensive approaches including mass spectrometry and reverse phase protein lysate arrays (RPPA). The purpose of this manuscript is to review the current protein markers that influence breast cancer prediction and prognosis and to focus on novel advances in proteomic classification of breast cancer.

    Breast cancer is the most frequently diagnosed neoplastic disease in women around menopause often leading to a significant reduction of these women's ability to function normally in everyday life. The increased breast cancer incidence observed in epidemiological studies in a group of women actively participating in social and professional life implicates the necessity of conducting multidirectional studies in order to identify risk factors associated with the occurrence of this type of neoplasm. Taking the possibility of influencing the neoplastic transformation process in individuals as a criterion, all the risk factors initiating the process can be divided into two groups. The first group would include inherent factors such as age, sex, race, genetic makeup promoting familial occurrence of the neoplastic disease or the occurrence of benign proliferative lesions of the mammary gland. They all constitute independent parameters and do not undergo simple modification in the course of an individual's life. The second group would include extrinsic factors conditioned by lifestyle, diet or long-term medical intervention such as using oral hormonal contraceptives or hormonal replacement therapy and their influence on the neoplastic process may be modified to a certain degree. Identification of modifiable factors may contribute to development of prevention strategies decreasing breast cancer incidence. PMID:26528110

    With mammography firmly established as an integral part of efforts to reduce breast cancer mortality, many believe it is time to concentrate on prevention. Part of the multifaceted approach to preventing and treating this disease is unraveling its molecular, genetic and physiological makeup. Another aspect is ensuring that women have the information they need to make informed decisions about screening and treatment. Studies also point to the influence of nutrition, exercise, medicines and a patient's adherence to screening on cancer risk and recovery. PMID:20445140

    Full Text Available Background. Tumour characteristics are the most important prognostic factors in breast cancer. Patient-related factors such as young age at diagnosis, obesity, and smoking behaviour may also modify disease outcome. Due to the absence of a unique definition for “young age breast cancer” and the resulting variation in disease management, findings on the association between young age and prognosis of breast cancer are controversial. Methods. This study included 1500 patients with a primary diagnosis of breast cancer in six Iranian hospitals from 5 provinces. We modelled the relative excess risk (RER of breast cancer death to age at diagnosis and tumour characteristics. Results. Excess risks of death were observed for stage IV disease and poorly differentiated tumours: RER of 4.3 (95% CI: 1.05–17.65 and 3.4 (95% CI: 1.17–9.87, respectively. “Older” patients, particularly those aged 50 and over, presented more often with advanced and poorly differentiated tumours (P=0.001. After adjustment for stage, histological grade, Her-2 expression, estrogen and progesterone receptors, and place of residency, breast cancer mortality was not significantly different across age groups. Conclusion. We conclude that there is no prognostic effect of age at diagnosis of breast cancer among breast cancer patients treated at cancer centres in different parts of Iran; young and relatively old women have similar risks of dying from breast cancer.

    Full Text Available Inflammatory cytokines within the tumor microenvironment are linked to progression in breast cancer. Interleukin- (IL- 19, part of the IL-10 family, contributes to a range of diseases and disorders, such as asthma, endotoxic shock, uremia, psoriasis, and rheumatoid arthritis. IL-19 is expressed in several types of tumor cells, especially in squamous cell carcinoma of the skin, tongue, esophagus, and lung and invasive duct carcinoma of the breast. In breast cancer, IL-19 expression is correlated with increased mitotic figures, advanced tumor stage, higher metastasis, and poor survival. The mechanisms of IL-19 in breast cancer have recently been explored both in vitro and in vivo. IL-19 has an autocrine effect in breast cancer cells. It directly promotes proliferation and migration and indirectly provides a microenvironment for tumor progression, which suggests that IL-19 is a prognostic marker in breast cancer and that antagonizing IL-19 may have therapeutic potential.

    Breast cancer in men is a rare disease, accounting for approximately 1% of all breast cancer cases. Although the epidemiologic literature regarding female breast cancer is extensive, relatively little is known about the etiology of male breast cancer (MBC). This review is intended to summarize the existing body of evidence on genetic and epidemiologic risk factors for breast cancer in men. Overall, the epidemiology of MBC presents similarities with the epidemiology of female breast cancer. Major genetic factors associated with an increased risk of breast cancer for men include BRCA2 mutations, which are believed to account for the majority of inherited breast cancer in men, Klinefelter syndrome, and a positive family history. Suspected genetic factors include AR gene mutations, CYP17 polymorphism, Cowden syndrome, and CHEK2. Epidemiologic risk factors for MBC include disorders relating to hormonal imbalances, such as obesity, testicular disorders (e.g., cryptorchidism, mumps orchitis, and orchiectomy), and radiation exposure. Suspected epidemiologic risk factors include prostate cancer,prostate cancer treatment, gynecomastia, occupational exposures (e.g., electromagnetic fields, polycyclic aromatic hydrocarbons, and high temperatures), dietary factors (e.g., meat intake and fruit and vegetable consumption), and alcohol intake.

  18. Breast cancer therapies weighed

    International Nuclear Information System (INIS)

    Even as the National Institutes of Health came under fire last week for giving short shrift to women in the institute's basic and clinical research programs, the report of a recent NIH consensus conference points up the need for more research on how to treat early breast cancer. Although the experts were able to agree on the best surgical treatment for women with early breast cancer, they couldn't resolve the more controversial issue of whether the patients should subsequently receive systemic treatment - chemotherapy or hormone therapy - to prevent recurrence of their disease. The panel reaffirmed that the removal of the lump and nearby lymph nodes, followed by irradiation, is just as effective as a mastectomy. But then came the contentious question: should women with early breast cancer, especially those without detectable lymph node metastases, receive drug therapy to prevent recurrence of the disease? Currently, 70% of such cancers are successfully treated with surgery and radiation alone. For this reason, about 2 years ago, the National Cancer Institute issued a clinical alert saying that addition treatment with drugs or hormones is a credible therapeutic option worthy of careful attention for all early stage patients. This pronouncement engendered a storm of criticism. A consensus panel concluded that in cases where tumors are 1 centimeter or less in diameter and no lymph nodes are affected, the likelihood of recurrence is so small that the benefits of adjuvant therapy would be insignificant. But for the patients with larger tumors, the panel concluded that the decision is an individual one that depends on personal preferences and a variety of prognostic factors that can help to indicate whether a woman is at high risk of having a recurrence and should therefore have adjuvant therapy

    Highlights: • In non-triple negative breast cancer, metabolic parameter (SUVmax) was significantly correlated with perfusion parameters (Kep and Ve). • In triple negative cancers, any perfusion parameters did not correlated with metabolic parameters. • Higher SUVmax, higher SUVmax/Ktrans, higher MTV50/Ktrans, higher TLG50/Ktrans, higher TLG50/Ve ratios were significantly correlated with TNBC. • In triple negative breast cancer, perfusion and metabolic parameters are not significantly correlated. • Triple negative breast cancer showed higher metabolic–perfusion ratios compared to non-triple negative breast cancer. - Abstract: Objective: Our purpose was to evaluate whether breast cancer with high metabolic–perfusion ratio would be associated with poor histopathologic prognostic factors and whether triple negative breast cancer (TNBC) would show high metabolic–perfusion ratio compared to non-triple negative breast cancer (non-TNBC). Methods: From March 2011 to November 2011, 67 females with invasive ductal carcinoma of breast who underwent both MRI and 18F-FDG PET/CT were included. Perfusion parameters including Ktrans, Kep and Ve were acquired from Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Metabolic parameters including the standardized uptake value (SUV) and volumetric metabolic parameters including metabolic tumor volume (MTV) and total lesion glycolysis (TLG) were obtained from F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). Results: In non-TNBC, SUVmax was significantly correlated with Kep (ρ = 0.298, p = 0.036) and Ve (ρ = −0.286, p = 0.044). In TNBC, there was no significant correlation between all perfusion and metabolic parameters.

  4. The prognostic role of 99mTc-MDP breast scintigraphy. Comparison of scintigrafic findings with histologic and molecular parameters

    International Nuclear Information System (INIS)

    Breast scintigraphy (BS) with the bone-seeking agent 99mTc-medronate (MDP) can be usefully combined with mammography to diagnose and characterize questionable breast lumps. However this radiotracer does not seem to provide any further prognostic information about breast cancer. Therefore it is investigated the prognostic yield of MDP-BS searching for correlations between scintigraphic findings and the major biological and histologic parameters. It is retrospectively analyzed a series of 44 primary breast cancers. All patients had undergone 99mTc-MDP bone scan for preoperative staging, as well as conventional breast imaging. It is statistically compared the cancer/background ratio (c/b index) with lesion histotype, diameter, grading, and the tissue concentrations of steroid receptors, cathepsine D, type 1 timidine kinase, pS2 and p53 proteins). Differently from BS with 99mTc-MIBI, 201Tl, 18F-FDG, 111In-OCT and radiolabeled estrogens and despite its good overall accuracy, MDP-BS appears to have no prognostic role. In fact, despite the well-known capability of soft tissue lesions to take up the tracer, MDP tumor trapping seems to depend mainly on the increased permeability of neo vessels and on interstitial space enlargement. Few reports are available in the literature on the correlation between in vivo MDP uptake by the breast cancer and prognostic parameters. Thus, it are tested possible correlations between the amount of MDP taken up by the breast cancer, histologic features and cell concentrations of some major biomarkers. The lack of any statistical significance is in agreement with the theory, and confirms the little prognostic value of MDP-BS. Nevertheless, further trials are warranted on larger series of cases to validate personal findings

    Full Text Available Abstract Background Gastrointestinal metastsasis from the breast cancer are rare. We report a patient who presented with intestinal obstruction due to solitary caecal metastasis from infiltrating ductal carcinoma of breast. We also review the available literature briefly. Case presentation A 72 year old lady with past history of breast cancer presented with intestinal obstruction due to a caecal mass. She underwent an emergency right hemicolectomy. The histological examination of the right hemicolectomy specimen revealed an adenocarcinoma in caecum staining positive for Cytokeratin 7 and Carcinoembryonic antigen and negative for Cytokeratin 20, CDX2 and Estrogen receptor. Eight out of 11 mesenteric nodes showed tumour deposits. A histological diagnosis of metastatic breast carcinoma was given. Conclusion To the best of our knowledge, this is the first case report of solitary metastasis to caecum from infiltrating ductal carcinoma of breast. Awareness of this possibility will aid in appropriate management of such patients.

  7. Management of breast cancer following Hodgkin's disease

    International Nuclear Information System (INIS)

    Purpose: To evaluate the incidence, histology, risk factors, treatment, and prognosis of breast cancer occurring after Hodgkin's disease. Materials and Methods: Sixty-five cases of breast cancer in 61 survivors of Hodgkin's lymphoma were analyzed. The median age at treatment for Hodgkin's disease was 24.1 [range (R): 13.3 - 71.8] years. Fifty-one percent had received radiotherapy alone, 47% radiation and chemotherapy, and 2% chemotherapy only. Relative and absolute risks were calculated based on 47 invasive breast cancers in 1049 women treated for Hodgkin's disease at Stanford. Results: The median age at diagnosis of breast cancer was 41.9 (R: 23.0 - 79.1) years; 76% of women were premenopausal. The median interval between Hodgkin's disease and breast cancer was 17.6 (R: 1.5 - 32.7) years with an increasing incidence beginning eight years after radiotherapy. The current relative risk of invasive breast cancer following Hodgkin's disease is 4.7 [95% confidence interval (CI): 3.4 - 6.1] with an absolute risk of 29.5 (CI: 18.8 - 40.2) excess cases per 10,000 person-years. Eighty-seven percent of breast cancers occurred in or at the margin of a prior radiotherapy field where a mean dose of 43.5 (R: 24.0 - 51.0) Gy was delivered. There was a family history of breast cancer in 31% of women. Cancers were detected by self examination (66%), screening mammography (27%), and physician examination (7%). Many tumors (60%) were located in the upper outer quadrants, corresponding to the axillary portion of a mantle field. There were seven cases of carcinoma in situ: six DCIS and one LCIS. The histologic distribution of invasive tumors paralleled that reported in the general population: 4% pure lobular, 35% high grade ductal, 45% intermediate grade ductal, 7% low-grade ductal, 4% tubular, 2% medullary, and 2% mucinous. Estrogen receptors were positive in 59% of evaluable cases. While 90% of invasive tumors were smaller than four centimeters, 96% were managed with mastectomy

    International Nuclear Information System (INIS)

    Breast cancer is the most commonly diagnosed cancer and leading cause of cancer mortality in women worldwide. Nearly half of the global total of breast cancer cases occurs in patients > 65 years of age. Advanced age at the diagnosis of breast cancer is associated with more favorable tumor biology, as indicated by increased hormone sensitivity, attenuated HER- 2/neu overexpression, and lower grades and proliferative indices Elderly patients, however, are more likely to present with larger and more advanced tumors, and recent reports suggest that lymph node involvement increases with age. Elderly patients care less likely to be treated according to accepted treatment guidelines and under treatment can, as a consequence, have a strong negative impact on survival.Breast cancer in elderly patients represents a great social problem and is expected to remain one of the most common cancers in the next half century.

  20. Risk Factors for Invasive Epithelial Ovarian Cancer by Histologic Subtype

    2004-10-01

    Full Text Available It is unclear whether the different histologic subtypes of epithelial ovarian carcinoma have different risk factors. We investigated the relationships between selected epidemiologic variables (i.e., parity, family history of ovarian cancer, oral contraceptive use, a history of tubal ligation and noncontraceptive estrogen use and the major histologic subtypes of epithelial ovarian cancer in a hospital-based case-control study of adult women at Roswell Park Cancer Institute in Buffalo, NY, USA. Multivariate unconditional logistic regression models were used for statistical analysis. We observed a pattern of increased risk associated with family history and a pattern of risk reduction associated with parity, noncontraceptive estrogen use and tubal ligation across all histologic subtype groups. However, we did not observe a consistent pattern of risk associated with oral contraceptive use. These results provide some additional support for the hypothesis that the effects of various ovarian cancer risk factors may differ according to the histologic subtype.

  1. Aluminium, antiperspirants and breast cancer.

    Aluminium salts are used as the active antiperspirant agent in underarm cosmetics, but the effects of widespread, long term and increasing use remain unknown, especially in relation to the breast, which is a local area of application. Clinical studies showing a disproportionately high incidence of breast cancer in the upper outer quadrant of the breast together with reports of genomic instability in outer quadrants of the breast provide supporting evidence for a role for locally applied cosmetic chemicals in the development of breast cancer. Aluminium is known to have a genotoxic profile, capable of causing both DNA alterations and epigenetic effects, and this would be consistent with a potential role in breast cancer if such effects occurred in breast cells. Oestrogen is a well established influence in breast cancer and its action, dependent on intracellular receptors which function as ligand-activated zinc finger transcription factors, suggests one possible point of interference from aluminium. Results reported here demonstrate that aluminium in the form of aluminium chloride or aluminium chlorhydrate can interfere with the function of oestrogen receptors of MCF7 human breast cancer cells both in terms of ligand binding and in terms of oestrogen-regulated reporter gene expression. This adds aluminium to the increasing list of metals capable of interfering with oestrogen action and termed metalloestrogens. Further studies are now needed to identify the molecular basis of this action, the longer term effects of aluminium exposure and whether aluminium can cause aberrations to other signalling pathways in breast cells. Given the wide exposure of the human population to antiperspirants, it will be important to establish dermal absorption in the local area of the breast and whether long term low level absorption could play a role in the increasing incidence of breast cancer.

    Full Text Available Both diet and nutrition have been studied in relationship with breast cancer risk, as the great variation among different countries in breast cancer incidence could possibly be explained through the inflammatory and immune response, as well as antioxidant intake, among others.To date, no clear association with diet beyond overweight and weight gain has been found, except for alcohol consumption. Nonetheless, the small number of studies done in middle to low income countries where variability of food intake is wider,is beginning to show interesting results.Tanto la dieta como la nutrición han sido estudiadas en relación con el riesgo de cáncer de mama, dada la gran variación de incidencia de cáncer entre países, y la posibilidad de explicarla a través de la respuesta inflamatoria o inmune, así como ingesta de antioxidantes,entre otros.Hasta la fecha, ninguna asociación clara con la dieta ha sido encontrada, excepto para el consumo de alcohol, más allá del sobrepeso y del incremento de peso. Sin embargo, los estudios que se están realizando en países de mediano a bajo nivel de ingresos, con mayor variabilidad de ingesta de alimentos, comienzan a mostrar resultados interesantes.

  5. Breast cancer during pregnancy and lactation

    International Nuclear Information System (INIS)

    We report 3 cases of gestational breast cancer that were encountered by the authors over a year period (1998) and discuss the diagnostic dilemma and modern management options. The first case was a 38-year-old Saudi female who was 8 month pregnant presented with 3 month history of left breast lump and intermittent bloody nipple discharge. She started menarche at the age of 13 years and denied any past history of benign breast diseases or oral contraceptive pill. There was no family history of malignant breast disease. Clinical examination revealed an irregular hard lump (3x3 cm) in the subareolar area of the left breast with no palpable axillary or supraclavicular lymph nodes. Fine needle aspiration cytology (FNAC) showed infiltrating ductal carcinoma. She underwent left simple mastectomy and axillary clearance together with cesarian section (CS) and tubal ligation at the same time. Histology revealed grade II infiltrating ductal carcinoma with 2 of the 11 level I nodes were positive for malignancy. She later underwent adjuvant chemoradiation and remained well with no evidence of locoregional recurrence 34 months later. The second case was a 40-year-old Saudi female who has been lactating for 10 months presented with a left breast lump of one week duration. There was no history of breast pain or nipple discharge and denied any past history of benign breast disease. There was no family history of breast cancer. Clinically, there was a 2x3 cm irregular left breast mass, in the upper outer quadrant with no palpable axillary lymphadenopathy. Mammography revealed suspicious opacity in the left breast but bone scan and ultrasonography showed no bone or liver metastases. Fine needle aspiration cytology showed suspicious of malignancy. She underwent a wide excision and left axillary clearance. Histopathology showed grade II medullary carcinoma and 2 out of 20 axillary lymph nodes were malignant. She later underwent systemic chemotherapy and radiation to left breast and

    The aim of this retrospective study was to determine if some features of baseline {sup 18}F-FDG PET images, including volume and heterogeneity, reflect clinical, histological or immunohistochemical characteristics in patients with stage II or III breast cancer (BC). Included in the present retrospective analysis were 171 prospectively recruited patients with stage II/III BC treated consecutively at Saint-Louis hospital. Primary tumour volumes were semiautomatically delineated on pretreatment {sup 18}F-FDG PET images. The parameters extracted included SUV{sub max}, SUV{sub mean}, metabolically active tumour volume (MATV), total lesion glycolysis (TLG) and heterogeneity quantified using the area under the curve of the cumulative histogram and textural features. Associations between clinical/histopathological characteristics and {sup 18}F-FDG PET features were assessed using one-way analysis of variance. Areas under the ROC curves (AUC) were used to quantify the discriminative power of the features significantly associated with clinical/histopathological characteristics. T3 tumours (>5 cm) exhibited higher textural heterogeneity in {sup 18}F-FDG uptake than T2 tumours (AUC <0.75), whereas there were no significant differences in SUV{sub max} and SUV{sub mean}. Invasive ductal carcinoma showed higher SUV{sub max} values than invasive lobular carcinoma (p = 0.008) but MATV, TLG and textural features were not discriminative. Grade 3 tumours had higher FDG uptake (AUC 0.779 for SUV{sub max} and 0.694 for TLG), and exhibited slightly higher regional heterogeneity (AUC 0.624). Hormone receptor-negative tumours had higher SUV values than oestrogen receptor-positive (ER-positive) and progesterone receptor-positive tumours, while heterogeneity patterns showed only low-level variation according to hormone receptor expression. HER-2 status was not associated with any of the image features. Finally, SUV{sub max}, SUV{sub mean} and TLG significantly differed among the three

  9. Estrogen and progesterone receptor levels in nonneoplastic breast epithelium of breast cancer cases versus benign breast biopsy controls

    International Nuclear Information System (INIS)

    Previous studies and biological mechanisms of carcinogenesis suggest that the steroid receptor content of benign breast epithelium may be related to breast cancer risk. The objective in this study was to compare the levels of estrogen receptor-α (ER) and progesterone receptor (PR) in nonneoplastic breast epithelium between breast cancer cases and biopsy controls. Between 1995 and 1997 at two sites (Women's College Hospital in Toronto and Kingston General Hospital), 667 women who were scheduled for diagnostic excisional breast biopsies completed a questionnaire providing personal information and agreed to allow analysis of routinely resected tissue. Histological slides with nonneoplastic epithelium were available for 101 cancer cases and 200 biopsy controls in Toronto and for 105 cancer cases and 119 controls in Kingston. Nonneoplastic epithelium was examined with immunohistochemical assays to determine the percent of epithelial cells staining for ER and PR. Unconditional logistic regression was used to calculate odds ratios (OR) stratified by study site. The ER content of nonneoplastic tissue was higher in cases than biopsy controls in unadjusted analyses; after adjustment for age, however, a weak association remained in only one of the study sites. After adjustment for age, the PR content of nonneoplastic tissue was slightly lower in breast cancer cases than controls in one study site. Furthermore, this inverse association was confined to women with PR negative breast cancer in comparison to the controls. No interaction between ER and PR content of nonneoplastic tissue was observed in relation to the odds of having breast cancer. The results of this study are consistent with only a slight indication of increased ER levels in nonneoplastic tissue in breast cancer cases relative to controls. This study contributes to the understanding of breast cancer by examining both ER and PR in nonneoplastic tissue. Limitations remain, however, such as the necessity of

  10. HER2-positive breast cancer patients: correlation between mammographic and pathological findings

    International Nuclear Information System (INIS)

    Human epidermal growth factor receptor 2 (HER2)-positive breast cancers represent a highly aggressive breast cancer subtype and are associated with a worse prognosis. This study was designed to investigate the mammography finding of HER2-positive breast cancer and to compare the results with the characteristics of HER2-negative breast cancer patients. From January 2010 to October 2011, mammography findings of 65 patients with pathologically confirmed HER2-positive breast cancers (n = 22) or HER2-negative breast cancers (n = 43) were retrospectively reviewed. The authors also reviewed pathological reports for information on the histological type and differentiation grade. Among the two types of breast cancer patients, estrogen receptor-negative/PR-negative/HER2-positive breast cancer patients most commonly had associated calcifications (18 of 22) on mammography. On mammography, cases with a cluster of calcifications usually were presented as pleomorphic calcifications (12 of 20) and branching calcifications (4 of 20). Patients with HER2-positive breast cancers showed a histological grade II. HER2- positive breast cancer patients usually had ductal invasive carcinoma (17 of 22). Moreover, postmenopausal patients showed a significantly higher frequency of HER2-positive tumours. Our results suggest that the imaging findings might be useful in diagnosing HER2-positive breast cancer patients. (authors)

HR+ means tumor cells have receptors for the hormones estrogen or progesterone, which can promote the growth of HR+ tumors. Hormone therapies like tamoxifen can be used to treat HR+ tumors. HER2 = Human epidermal growth Factor receptor, HER2+ means tumor cells overexpress (make high levels of) a protein, called HE2/neu, which has been shown to be associated with certain aggressive types of breast cancer. Trastuzumab and some other therapies can target cells that overexpress HER2. HR+/HER2, aka “LuminalA”. 73% of all breast cancer cases: best prognosis, most common subtype for every race, age, and poverty level. HR-/HER2, aka “Triple Negative”: 13% of all breast cancer cases, Worst prognosis, Non-Hispanic blacks have the highest rate of this subtype at every age and poverty level. HR+/HER2+, aka “Luminal B”, 10% of all breast cancer cases, little geographic variation by state.

    Male breast cancer (MaleBC) is a rare disease, accounting for development; low-penetrance gene mutations (i.e. CHEK-2) are more common but involve a lower risk increase. About 90% of all male breast tumors have proved to be invasive ductal carcinomas, expressing high levels of hormone receptors with evident therapeutic returns. The most common clinical sign of BC onset in men is a painless palpable retroareolar lump, which should be evaluated by means of mammography, ultrasonography and core biopsy or fine needle aspiration (FNA). To date, there are no published data from prospective randomized trials supporting a specific therapeutic approach in MaleBC. Tumor size together with the number of axillary nodes involved are the main prognostic factors and should guide the treatment choice. Locoregional approaches include surgery and radiotherapy (RT), depending upon the initial clinical presentation. When systemic treatment (adjuvant, neoadjuvant and metastatic) is delivered, the choice between hormonal and or chemotherapy (CT) should depend upon the clinical and biological features, according to the FBC management guidelines. However great caution is required because of high rates of age-related comorbidities. PMID:19427229

Breast cancer is especially known for long asymptomatic periods, up to 25 years, with no evidence of the disease, followed by a relapse. Factors that determine the cell's decision to enter a dormant state and that control its duration remain unclear. In recent years, considerable progress has been made in understanding how tumor cells circulating in the blood interact and extravasate into secondary sites and which factors might determine whether these cells survive, remain dormant, or become macrometastases. The mechanisms of tumor cell dormancy are still not clear. Two different hypotheses are currently discussed: tumor cells persist either by completely withdrawing from the cell cycle or by continuing to proliferate at a slow rate that is counterbalanced by cell death. Because dormant disseminated tumor cells may be the founders of metastasis, one hypothesis is that dormant tumor cells, or at least a fraction of them, share stem cell-like characteristics that may be responsible for their long half-lives and their suggested resistance to standard chemotherapy. Therefore, knowledge of the biology of tumor cell dormancy may be the basis from which to develop innovative targeted therapies to control or eliminate this tumor cell fraction. In this review, we discuss biological mechanisms and clinical implications of tumor dormancy in breast cancer patients.Keywords: tumor dormancy, disseminated tumor cell, circulating tumor cell, targeted therapy

    Mucinous carcinoma (MC) of the breast is very rare (∼1-7% of all breast cancers), invasive ductal carcinoma. Presence of pools of extracellular mucin is one of the most important histological features for MC. This paper aims at developing a quantitative computer-aided methodology for automated identification of mucin areas and its percentage using tissue histological images. The proposed method includes pre-processing (i.e., colour space transformation and colour normalization), mucin regions segmentation, post-processing, and performance evaluation. The proposed algorithm achieved 97.74% segmentation accuracy in comparison to ground truths. In addition, the percentage of mucin present in the tissue regions is calculated by the mucin index (MI) for grading MC (pure, moderately, minimally mucinous). PMID:26971129

We present the evaluation, treatment and outcome of male patients seen with breast cancer in our institution. Male patients that had histological diagnosis of breast cancer from 2001 to 2010 were retrospectively evaluated. After evaluation patients were treated with modified radical mastectomy. Combination chemotherapy was given to patients with positive axillary lymph nodes. Radiotherapy and hormonal therapy were also employed. There were 57 male patients with breast cancer which accounted for 9% of all breast cancers seen during the study period. Their mean age was 59 ± 2.3 years. The mean tumor diameter was 13 ± 2.5 cm. Fifty three (93% patients presented with advanced disease including 15 with distant metastasis. Four patients with stage II disease were treated with modified radical mastectomy, chemotherapy and tamoxifen. Of the 30 patients with sage III disease that had modified radical mastectomy, complete axillary clearance and tumor free margins were achieved in 25. Overall 21 (36.8% patients were tumor free at one year. Overall 5-year survival was 22.8%. In conclusion, male patients with breast cancer present with advanced disease which is associated with poor outcome of treatment.

    Protein tyrosine phosphatase non-receptor type 12 (PTPN12) is a recently identified tumor suppressor gene (TSG) that is frequently compromised in human triple-negative breast cancer. In the present study, we investigated the expression of PTPN12 protein by patients with breast cancer in a Chinese population and the relationship between PTPN12 expression levels and patient clinicopathological features and prognosis. Additionally, we explored the underlying down-regulation mechanism from the perspective of an epigenetic alteration. We examined PTPN12 mRNA expression in five breast cancer cell lines using semi-quantitative reverse-transcription PCR, and detected PTPN12 protein expression using immunohistochemistry in 150 primary invasive breast cancer cases and paired adjacent non-tumor tissues. Methylation-specific PCR was performed to analyze the promoter CpG island methylation status of PTPN12. PTPN12 was significantly down-regulated in breast cancer cases (48/150) compared to adjacent noncancerous tissues (17/150; P < 0.05). Furthermore, low expression of PTPN12 showed a significant positive correlation with tumor size (P = 0.047), lymph node metastasis (P = 0.001), distant metastasis (P = 0.009), histological grade (P = 0.012), and survival time (P = 0.019). Additionally, promoter CpG island hypermethylation occurs more frequently in breast cancer cases and breast cancer cell lines with low PTPN12 expression. Our findings suggest that PTPN12 is potentially a methylation-silenced TSG for breast cancer that may play an important role in breast carcinogenesis and could potentially serve as an independent prognostic factor for invasive breast cancer patients

    2015-01-01

    Full Text Available Background: Grading of breast carcinoma on fine needle aspiration cytology (FNAC is beneficial for selecting patients for neoadjuvant chemotherapy. Aims: To grade the breast carcinoma on FNAC using Robinson grading system and to assess the concordance of cytological grading (CG with histological grading (HG using Elston-Ellis modification of Scarff-Bloom-Richardson grading system. Materials and Methods: The study was conducted for 1-year, comprising of 50 female patients attending outpatient departments (OPD as well as admitted in various surgical wards of a teaching hospital, diagnosed as breast carcinoma. FNAC smears were stained with May-Grunwald-Giemsa and Papanicolaou (Pap stains and CG was done using Robinson system on Pap stained smears. The results were compared with HG system after resection of tumors. Results: Of 50 cases, 14 (28% cases were graded as grade I, 24 (48% grade II, and 12 (24% grade III by CG, whereas 9 (18%, 28 (56% and 13 (26% cases were graded as grade I, II and III by HG. The result showed overall 72% concordance of CG with HG, with grade II and grade III showing highest degree of concordance (83.33%, which is comparable to previous studies. Kappa measurement showed a higher degree of agreement in high-grade tumors compared with low-grade tumors (0.73 in grade III, 0.53 in grade II and 0.39 in grade I. Conclusion: Cytological grading is comparable to HG in majority of cases. Because neoadjuvant chemotherapy is becoming increasingly popular as primary treatment modality of breast cancer, CG could be a useful parameter in selecting the mode of therapy and predicting tumor behavior.

    Breast cancer is the second most common cause of death from cancer among women. Lifestyle changes are shown to be important in the prevention of breast cancer. Diet, physical activity, smoking, alcohol use, and vitamin and mineral use are key factors influencing the risk of breast cancer among women. Because these factors are related to each other, it is difficult to assess their individual roles in breast cancer. Some of these factors are alterable, meaning that women can decrease their risk...

  17. Breast MR imaging in women at high-risk of breast cancer. Is something changing in early breast cancer detection?

    International Nuclear Information System (INIS)

    In the last few years, several papers have addressed the introduction of contrast-enhanced MR imaging for screening women at high risk for breast cancer. Taking in consideration five prospective studies, on 3,571 screened women with hereditary predisposition to the disease and 9,652 rounds, we found that 168 patients were diagnosed with breast cancer (155 screen-detected, eight interval, and five cancers excluded from analysis) with a detection rate per year of 1.7%. These cancers were small (49% equal to or less than 10 mm in diameter) but aggressive, 82% being invasive and 49% with histologic grade 3; however, only 19% of these invasive cancers were associated with nodal involvement. The pooled sensitivity was 16% for clinical breast examination, 40% for mammography, 43% for ultrasound, and 81% for MR. The positive predictive value (calculated on the basis of the number of invasive diagnostic procedures due to false positives) was 33%, 47%, 18%, and 53%, respectively. Aim of the present article is to present the historical development of MR imaging of breast tumors that made this application theoretically and technically possible, to explain what strategic problems we face in the presence of a hereditary predisposition to the disease, to review the main results of the published studies, and to outline open problems and future perspectives.

  18. MRI Background Parenchymal Enhancement Is Not Associated with Breast Cancer.

    Directory of Open Access Journals (Sweden)

    Barbara Bennani-Baiti

    Full Text Available Previously, a strong positive association between background parenchymal enhancement (BPE at magnetic resonance imaging (MRI and breast cancer was reported in high-risk populations. We sought to determine, whether this was also true for non-high-risk patients.540 consecutive patients underwent breast MRI for assessment of breast findings (BI-RADS 0-5, non-high-risk screening (no familial history of breast cancer, no known genetic mutation, no prior chest irradiation, or previous breast cancer diagnosis and subsequent histological work-up. For this IRB-approved study, BPE and fibroglandular tissue FGT were retrospectively assessed by two experienced radiologists according to the BI-RADS lexicon. Pearson correlation coefficients were calculated to explore associations between BPE, FGT, age and final diagnosis of breast cancer. Subsequently, multivariate logistic regression analysis, considering covariate colinearities, was performed, using final diagnosis as the target variable and BPE, FGT and age as covariates.Age showed a moderate negative correlation with FGT (r = -0.43, p<0.001 and a weak negative correlation with BPE (r = -0.28, p<0.001. FGT and BPE correlated moderately (r = 0.35, p<0.001. Final diagnosis of breast cancer displayed very weak negative correlations with FGT (r = -0.09, p = 0.046 and BPE (r = -0.156, p<0.001 and weak positive correlation with age (r = 0.353, p<0.001. On multivariate logistic regression analysis, the only independent covariate for prediction of breast cancer was age (OR 1.032, p<0.001.Based on our data, neither BPE nor FGT independently correlate with breast cancer risk in non-high-risk patients at MRI. Our model retained only age as an independent risk factor for breast cancer in this setting.

  20. Upper limb lymphedema after breast cancer treatment

    International Nuclear Information System (INIS)

    Purpose. - To study the frequency and risk factors for upper limb lymphedema through a series of patients treated for breast cancer. Patients and methods. - It is a retrospective study about 222 patients treated for breast cancer during the period between February 1993 and December 2003 in Sfax hospitals. Average age was 51 years (27-92 years). Tumour was T2 in 59% of cases. All patients had surgery with lymph node dissection. Infiltrating ductal carcinoma was the most frequent histological type (80% of cases), with predominant SBR II grade (62%). The mean number of removed lymph nodes was 12 (2-33). Axillary lymph node metastasis was detected in 124 patients. Radiotherapy was delivered in 200 patients, including axillary irradiation in 30 cases. The mean follow-up was 68 months (12-120). Results. - Lymphedema appeared in 23% of cases (51 patients), 14 months after surgery (mean period). Lymphedema affected the brachium in 17% of cases, the forearm in 12% of cases and all upper limb in 71% of cases. Fifty percent of patients had rehabilitation. However, improvement of lymphedema was obtained in 18 cases. Parameters predicting lymphedema were studied. Significant risk factors were obesity, infection and a number of removed lymph node above 10. The type of surgery, axillary irradiation and shoulder abduction deficit did not predict lymphedema. Conclusion. - Lymphedema of the arm is a frequent consequence of breast cancer treatment. The risk of lymphedema is correlated with obesity, infection and a number of removed lymph node above 10.

    The prognostic value of tumor infiltrating lymphocytes in breast cancer has long been recognized by histopathologists. These observations were reaffirmed by recent immunohistochemistry and gene expression profiling studies that also revealed an association between greater chemotherapy sensitivity and extensive lymphocytic infiltration in early stage breast cancers treated with neoadjuvant chemotherapy. These results suggest that local anti-tumor immune response can at least partially control cancer growth and may mediate the antitumor effects of chemotherapy. However, until recently, there was no direct clinical evidence to demonstrate that enhancing anti-tumor immune response could lead to clinical benefit in breast cancer patients. The recent development of clinically effective immune checkpoint inhibitors made it possible to test the therapeutic impact of augmenting the local anti-tumor immune response. Two Phase I clinical trials using single agent anti-PD-1 (MK-3475, pembrolizumab) and anti-PD-L1 (MPDL3280A, atezolizumab) antibodies demonstrated close to 20% tumor response rates in heavily pretreated, metastatic, triple negative breast cancers. The most remarkable feature of the responses was their long duration. Several patients had disease control close to a year, or longer, which has not previously been seen with chemotherapy regimens in this patient population. A large number of clinical trials are currently underway with these and similar drugs in the neoadjuvant, adjuvant and metastatic settings to define the role of this new treatment modality in breast cancer.

    Full Text Available Breast cancer remains a major public health problem, being the second cause of cancer death in women. There is a marked tendency to restrict the extension of surgical gesture, which directly leads to two different attitudes: radical surgery and conservative surgery, to which, at least in our country, there are still some delays. Prospective and retrospective studies have shown that, in 20 years, conservative and radical therapy had about the same rate of survival and disease-free interval, at least for stage I and II breast cancer, the only real counterargument against conservative surgery being that, in principle, the higher rate of recurrence local constraint can be solved by postoperative radiotherapy. Finally, the survival rate is the main parameter of evaluation, assessing the effectiveness of the treatment in breast cancer, and in all its other forms.

    To evaluate factors affecting 18F-Fluorodeoxyglucose (FDG) uptake in breast cancer. For 3 years from 2006, 180 patients (mean age 48-years-old) with 187 breast cancers underwent positron emission tomography-computed tomography (PET/CT; biograph2, Siemens) at our institute and were enrolled in this study. We evaluated whether there was a correlation between the peak standardized uptake value (pSUV) of PET/CT and the histologic type of the breast cancers (n=187), grade of the invasive ductal cancers (n=142), and tumor size (n=153). The different histologic types of breast cancers include IDCs (n=156), in situ ductal carcinoma (n=10), papillary cancer (n=6), mucinous cancer (n=6), invasive lobular cancer (n=4), medullary cancer (n=3), metaplastic cancer (n=1), and neuroendocrine cancer (n=1). pSUV showed significant differences according to histologic type (p0.001). Regardless of histologic type, the larger the breast cancer, the higher the pSUV; in addition, the higher the grade of IDCs, the higher the pSUV. For the low grade IDCs, pSUV is correlated with tumor size; however, this is not the case in high grade IDCs

  5. The transcription factor REST is lost in aggressive breast cancer.

    Directory of Open Access Journals (Sweden)

    Matthew P Wagoner

    2010-06-01

    Full Text Available The function of the tumor suppressor RE1 silencing transcription factor (REST is lost in colon and small cell lung cancers and is known to induce anchorage-independent growth in human mammary epithelial cells. However, nothing is currently known about the role of this tumor suppressor in breast cancer. Here, we test the hypothesis that loss of REST function plays a role in breast cancer. To assay breast tumors for REST function, we developed a 24-gene signature composed of direct targets of the transcriptional repressor. Using the 24- gene signature, we identified a previously undefined RESTless breast tumor subtype. Using gene set enrichment analysis, we confirmed the aberrant expression of REST target genes in the REST-less tumors, including neuronal gene targets of REST that are normally not expressed outside the nervous system. Examination of REST mRNA identified a truncated splice variant of REST present in the REST-less tumor population, but not other tumors. Histological analysis of 182 outcome-associated breast tumor tissues also identified a subpopulation of tumors that lack full-length, functional REST and over-express the neuroendocrine marker and REST target gene Chromogranin A. Importantly, patients whose tumors were found to be REST-less using either the 24-gene signature or histology had significantly poorer prognosis and were more than twice as likely to undergo disease recurrence within the first 3 years after diagnosis. We show here that REST function is lost in breast cancer, at least in part via an alternative splicing mechanism. Patients with REST-less breast cancer undergo significantly more early disease recurrence than those with fully functional REST, regardless of estrogen receptor or HER2 status. Importantly, REST status may serve as a predictor of poor prognosis, helping to untangle the heterogeneity inherent in disease course and response to treatment. Additionally, the alternative splicing observed in REST

  6. Dermatologic radiotherapy and breast cancer

    International Nuclear Information System (INIS)

    This study was set up to provide quantitative data to evaluate unsubstantiated claims that improper dermatologic radiation techniques may cause breast cancer. A thin mylar window ionization rate meter placed at the location of the right breast of an Alderson-RANDO anthropomorphic phantom was used to measure direct and scatter radiation reaching the female breast during radiotherapy of the facial region (as given for acne). The results indicate that scatter doses are very small; they are influenced by radiation quality and the use or nonuse of a treatment cone. Quantitative risk estimates show that the very small risk of breast cancer induction can be reduced even further by the use of proper radiation protection measures. (orig.)

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

    2016-01-01

    Leptomeningeal metastasis (LM) is an uncommon presentation of relapse in breast cancer, which is associated with poor clinical outcomes and poor prognosis. Notably, LM most commonly occurs in breast cancer. The aim of the present review was to investigate the occurrence of LM as the primary presentation of relapse following remission in breast cancer patients and to determine whether specific histological subtypes are predisposed to meningeal metastases. In addition, the present review evaluated whether patients presenting with LM as the primary site of relapse exhibit differences in survival when compared with patients exhibiting metastasis to other sites. Cross-sectional studies have demonstrated that LM is commonly associated with other sites of distant metastasis including lung, liver and bone metastases. The histological breast cancer subtype most commonly associated with LM was invasive lobular carcinoma, while triple-negative breast cancer patients appear to be predisposed to the development of LM when considering the overall prevalence of histological breast cancer subtypes. At present, data regarding LM as the primary site of relapse are limited due to its rarity as the first site of metastasis in breast cancer. Case-controlled studies are required to investigate the incidence of LM as the primary site of recurrence in breast cancer patients as this would enable treatment standardization and identification of prognostic factors for improved survival.

    Breast cancer metastases to the stomach are infrequent, with an estimated incidence rate of approximately 0.3%. Gastric metastases usually are derived from lobular rather than from ductal breast cancer. The most frequent type of a breast cancer metastasis as seen on endoscopy to the stomach is linitis plastica; features of a metastatic lesion that resemble early gastric cancer (EGC) are extremely rare. In this report, we present a case of a breast cancer metastasis to the stomach from an infi...

    Automatic recognition of different tissue types in histological images is an essential part in the digital pathology toolbox. Texture analysis is commonly used to address this problem; mainly in the context of estimating the tumour/stroma ratio on histological samples. However, although histological images typically contain more than two tissue types, only few studies have addressed the multi-class problem. For colorectal cancer, one of the most prevalent tumour types, there are in fact no published results on multiclass texture separation. In this paper we present a new dataset of 5,000 histological images of human colorectal cancer including eight different types of tissue. We used this set to assess the classification performance of a wide range of texture descriptors and classifiers. As a result, we found an optimal classification strategy that markedly outperformed traditional methods, improving the state of the art for tumour-stroma separation from 96.9% to 98.6% accuracy and setting a new standard for multiclass tissue separation (87.4% accuracy for eight classes). We make our dataset of histological images publicly available under a Creative Commons license and encourage other researchers to use it as a benchmark for their studies. PMID:27306927

    Full Text Available Abstract Background NUCKS (Nuclear, Casein Kinase and Cyclin-dependent Kinase Substrate is a nuclear, DNA-binding and highly phosphorylated protein. A number of reports show that NUCKS is highly expressed on the level of mRNA in several human cancers, including breast cancer. In this work, NUCKS expression on both RNA and protein levels was studied in breast tissue biopsies consisted of invasive carcinomas, intraductal proliferative lesions, benign epithelial proliferations and fibroadenomas, as well as in primary cultures derived from the above biopsies. Specifically, in order to evaluate the level of NUCKS protein in correlation with the histopathological features of breast disease, immunohistochemistry was employed on paraffin sections of breast biopsies of the above types. In addition, NUCKS expression was studied by means of Reverse Transcription PCR (RT-PCR, real-time PCR (qRT-PCR and Western immunoblot analyses in the primary cell cultures developed from the same biopsies. Results The immunohistochemical Results showed intense NUCKS staining mostly in grade I and II breast carcinomas compared to normal tissues. Furthermore, NUCKS was moderate expressed in benign epithelial proliferations, such as adenosis and sclerosing adenosis, and highly expressed in intraductal lesions, specifically in ductal carcinomas in situ (DCIS. It is worth noting that all the fibroadenoma tissues examined were negative for NUCKS staining. RT-PCR and qRT-PCR showed an increase of NUCKS expression in cells derived from primary cultures of proliferative lesions and cancerous tissues compared to the ones derived from normal breast tissues and fibroadenomas. This increase was also confirmed by Western immunoblot analysis. Although NUCKS is a cell cycle related protein, its expression does not correlate with Ki67 expression, neither in tissue sections nor in primary cell cultures. Conclusion The results show overexpression of the NUCKS protein in a number of non

    Full Text Available Benign breast lesions (BBL includes a wide variety of histologic entities, which have been broadly classified into non-proliferative lesions, proliferative lesions without atypia, and hyperplasia with atypia. With the increased use of mammography, more benign lesions are being detected, and in order to estimate the risk of breast cancer for specific histologic categories is of great importance to guide clinical management. Women with proliferative lesions without atypia are at slightly increased risk of subsequent breast cancer, whereas women with proliferative lesions with atypia have a higher risk. The risk is 1.5- 2-fold in women with proliferative lesions without atypia, 4-5-fold in women with proliferative lesions with atypia, and 8-10 fold in women with ductal carcinoma in situ. Age at diagnosis of BBL, menopausal status, family history of breast cancer in a first-degree relative, and time since BBL diagnosis on risk of breast cancer are important for risk evaluation.

  4. Breast cancer epidemiology and risk factors

    International Nuclear Information System (INIS)

    Breast cancer is the most common malignancy among women in the Western society. Over the past decades it has become apparent that breast cancer incidence rates are increasing steadily, whereas the mortality rates for breast cancer have remained relatively constant. Information through the media on this rising number of cases has increased breast health awareness but has also introduced anxiety in the female population. This combination of factors has made the need for prevention of breast cancer an urgent matter. Breast cancer does not seem to be a single disease entity. A specific etiologic factor may therefore have more influence on one form may therefore have more influence on one form of breast cancer than another. So far though, as shown in their summary of current knowledge on established and dubious risk factors, no risk factors have been identified that can explain a major part of the incidence. Efforts to identify other ways for primary prevention have also been discouraging, even though breast cancer is one of the most investigated tumours world-wide. Thus, at this point i time, the most important strategy to reduce breast cancer mortality is early detection through individual counselling and organised breast screening programs. The recent isolation of breast cancer susceptibility genes may introduce new ways to reduce the risk of breast cancer in a small subset of women

    Full Text Available BACKGROUND: A Mediterranean diet has a recognized beneficial effect on health and longevity, with a protective influence on several cancers. However, its association with breast cancer risk remains unclear. OBJECTIVE: We aimed to investigate whether adherence to a Mediterranean dietary pattern influences breast cancer risk. DESIGN: The Swedish Women's Lifestyle and Health cohort study includes 49,258 women aged 30 to 49 years at recruitment in 1991-1992. Consumption of foods and beverages was measured at enrollment using a food frequency questionnaire. A Mediterranean diet score was constructed based on the consumption of alcohol, vegetables, fruits, legumes, cereals, fish, the ratio of unsaturated to saturated fat, and dairy and meat products. Relative risks (RR for breast cancer and specific tumor characteristics (invasiveness, histological type, estrogen/progesterone receptor status, malignancy grade and stage associated with this score were estimated using Cox regression controlling for potential confounders. RESULTS: 1,278 incident breast cancers were diagnosed. Adherence to a Mediterranean dietary pattern was not statistically significantly associated with reduced risk of breast cancer overall, or with specific breast tumor characteristics. A RR (95% confidence interval for breast cancer associated with a two-point increment in the Mediterranean diet score was 1.08 (1.00-1.15 in all women, and 1.10 (1.01-1.21 and 1.02 (0.91-1.15 in premenopausal and postmenopausal women, respectively. When alcohol was excluded from the Mediterranean diet score, results became not statistically significant. CONCLUSIONS: Adherence to a Mediterranean dietary pattern did not decrease breast cancer risk in this cohort of relatively young women.

    Recent studies suggest that microRNAs show promise as excellent biomarkers for breast cancer; however there is still a high degree of variability between studies making the findings difficult to interpret. In addition to blood, ductal lavage (DL) and nipple aspirate fluids represent an excellent opportunity for biomarker detection because they can be obtained in a less invasive manner than biopsies and circumvent the limitations of evaluating blood biomarkers with regards to tissue of origin specificity. In this study, we have investigated for the first time, through a real-time PCR array, the expression of 742 miRNAs in the ductal lavage fluid collected from 22 women with unilateral breast tumors. We identified 17 differentially expressed miRNAs between tumor and paired normal samples from patients with ductal breast carcinoma. Most of these miRNAs have various roles in breast cancer tumorigenesis, invasion and metastasis, therapeutic response, or are associated with several clinical and pathological characteristics of breast tumors. Moreover, some miRNAs were also detected in other biological fluids of breast cancer patients such as serum (miR-23b, -133b, -181a, 338-3p, -625), plasma (miR-200a), and breast milk (miR-181a). A systems biology analysis of these differentially expressed miRNAs points out possible pathways and cellular processes previously described as having an important role in breast cancer such as Wnt, ErbB, MAPK, TGF-β, mTOR, PI3K-Akt, p53 signaling pathways. We also observed a difference in the miRNA expression with respect to the histological type of the tumors. In conclusion, our findings suggest that miRNA analysis of breast ductal fluid is feasible and potentially very useful for the detection of breast cancer. PMID:26984519

    Full Text Available Abstract Background Breast cancer is the most common cancer and the leading cause of cancer mortality in women worldwide. Hypoxia is an important factor involved in the progression of solid tumors and has been associated with various indicators of tumor metabolism, angiogenesis and metastasis. But little is known about the contribution of Hypoxia-Inducible Factor-2a (HIF-2a to the drug resistance and the clinicopathological characteristics in breast cancer. Methods Immunohistochemistry was employed on the tissue microarray paraffin sections of surgically removed samples from 196 invasive breast cancer patients with clinicopathological data. The correlations between the expression of HIF-2a and ABCG2 as well as other patients' clinicopathological data were investigated. Results The results showed that HIF-2a was expressed in different intensities and distributions in the tumor cells of the breast invasive ductal carcinoma. A positive staining for HIF-2a was defined as a brown staining observed mainly in the nucleus. A statistically significant correlation was demonstrated between HIF-2a expression and ABCG2 expression (p = 0.001, histology-grade (p = 0.029, and Ki67 (p = 0. 043 respectively. Conclusion HIF-2a was correlated with ABCG2 expression, histology-grade and Ki67 expression in breast invasive ductal carcinoma. HIF-2a could regulate ABCG2 in breast cancer cells, and could be a novel potential bio-marker to predict chemotherapy effectiveness. The hypoxia/HIF-2a/ABCG2 pathway could be a new mechanism of breast cancer multidrug-resistance. Virtual slides http://www.diagnosticpathology.diagnomx.eu/vs/2965948166714795

    Full Text Available Purpose: Human papillomaviruses (HPV may have a role in some breast cancers. The purpose of this study is to fill important gaps in the evidence. These gaps are: (i confirmation of the presence of high risk for cancer HPVs in breast cancers, (ii evidence of HPV infections in benign breast tissues prior to the development of HPV positive breast cancer in the same patients, (iii evidence that HPVs are biologically active and not harmless passengers in breast cancer.Methods: RNA-seq data from The Cancer Genome Atlas (TCGA was used to identify HPV RNA sequences in breast cancers. We also conducted a retrospective cohort study based on polymerase chain reaction (PCR analyses to identify HPVs in archival specimens from Australian women with benign breast biopsies who later developed breast cancer. To assess whether HPVs in breast cancer were biologically active, the expression of the oncogenic protein HPV E7 was assessed by immunohistochemistry (IHC.Results: Thirty (3.5% low risk and 20 (2.3% high risk HPV types were identified in 855 breast cancers from the TCGA data base. The high risk types were HPV 18 (48%, HPV 113 (24%, HPV 16 (10%, HPV 52 (10%. Data from the PCR cohort study, indicated that HPV type 18 was the most common type identified in breast cancer specimens (55% of 40 breast cancer specimens followed by HPV 16 (13%.

HPV E7 proteins were identified in 72% of benign breast specimens and 59% of invasive breast cancer specimens.Conclusions: There were 4 observations of particular interest: (i confirmation by both NGS and PCR of the presence of high risk HPV gene sequences in breast cancers, (ii a correlation between high risk HPV in benign breast specimens and subsequent HPV positive breast cancer in the same patient, (iii HPVs in breast cancer are likely to be biologically active (as shown by transcription of HPV DNA to RNA plus the expression of

  20. Genome evolution during progression to breast cancer

    KAUST Repository

    Newburger, D. E.

    2013-04-08

    Cancer evolution involves cycles of genomic damage, epigenetic deregulation, and increased cellular proliferation that eventually culminate in the carcinoma phenotype. Early neoplasias, which are often found concurrently with carcinomas and are histologically distinguishable from normal breast tissue, are less advanced in phenotype than carcinomas and are thought to represent precursor stages. To elucidate their role in cancer evolution we performed comparative whole-genome sequencing of early neoplasias, matched normal tissue, and carcinomas from six patients, for a total of 31 samples. By using somatic mutations as lineage markers we built trees that relate the tissue samples within each patient. On the basis of these lineage trees we inferred the order, timing, and rates of genomic events. In four out of six cases, an early neoplasia and the carcinoma share a mutated common ancestor with recurring aneuploidies, and in all six cases evolution accelerated in the carcinoma lineage. Transition spectra of somatic mutations are stable and consistent across cases, suggesting that accumulation of somatic mutations is a result of increased ancestral cell division rather than specific mutational mechanisms. In contrast to highly advanced tumors that are the focus of much of the current cancer genome sequencing, neither the early neoplasia genomes nor the carcinomas are enriched with potentially functional somatic point mutations. Aneuploidies that occur in common ancestors of neoplastic and tumor cells are the earliest events that affect a large number of genes and may predispose breast tissue to eventual development of invasive carcinoma.

    2012-02-01

    Full Text Available Background: Clinical experiences have revealed that patients with breast cancer experience various sexual problems following their treatment. Breast cancer negatively impacts the sexual life of the afflicted couples, and as a traumatic event can influence women’s psychosexual functioning and intimate relationship. This review focuses on sexuality after breast cancer and on a growing need for bio-psycho-social guidelines for breast cancer treatment. Methods: This study aims to review the literature on management, psychological outcomes and sexual dysfunction in patients with breast cancer. Results: Although the benefits of the current treatment strategies are well established, many cancer survivors are at risk for developing psycho physiological symptoms including sexual dysfunction. Cancer and treatment-related factors can influence sexual functioning. We review current treatment -related side effects on sexual functioning such as desire, arousal and orgasm in breast cancer patients. Despite the impact of medical treatment on survival of patients with breast cancer, no satisfactory steps have been taken towards improving sexual functioning of these patients. Conclusion: Breast cancer affects many aspects of sexuality, including changes in physical functioning and in the perception of feminity. Sexual dysfunction following breast cancer should be diagnosed and managed as a systematic approach with multidisciplinary inputs. Healthcare professionals should assess the effects of medical and surgical treatment on the sexuality of breast cancer survivors.

    Patient-tailored treatments for breast cancer are based on histological and immunohistochemical (IHC) subtypes. Magnetic Resonance Imaging (MRI) texture analysis (TA) may be useful in non-invasive lesion subtype classification. Women with newly diagnosed primary breast cancer underwent pre-treatment dynamic contrast-enhanced breast MRI. TA was performed using co-occurrence matrix (COM) features, by creating a model on retrospective training data, then prospectively applying to a test set. Analyses were blinded to breast pathology. Subtype classifications were performed using a cross-validated k-nearest-neighbour (k = 3) technique, with accuracy relative to pathology assessed and receiver operator curve (AUROC) calculated. Mann-Whitney U and Kruskal-Wallis tests were used to assess raw entropy feature values. Histological subtype classifications were similar across training (n = 148 cancers) and test sets (n = 73 lesions) using all COM features (training: 75 %, AUROC = 0.816; test: 72.5 %, AUROC = 0.823). Entropy features were significantly different between lobular and ductal cancers (p < 0.001; Mann-Whitney U). IHC classifications using COM features were also similar for training and test data (training: 57.2 %, AUROC = 0.754; test: 57.0 %, AUROC = 0.750). Hormone receptor positive and negative cancers demonstrated significantly different entropy features. Entropy features alone were unable to create a robust classification model. Textural differences on contrast-enhanced MR images may reflect underlying lesion subtypes, which merits testing against treatment response. (orig.)

  3. Magnetic resonance imaging texture analysis classification of primary breast cancer

    International Nuclear Information System (INIS)

    Patient-tailored treatments for breast cancer are based on histological and immunohistochemical (IHC) subtypes. Magnetic Resonance Imaging (MRI) texture analysis (TA) may be useful in non-invasive lesion subtype classification. Women with newly diagnosed primary breast cancer underwent pre-treatment dynamic contrast-enhanced breast MRI. TA was performed using co-occurrence matrix (COM) features, by creating a model on retrospective training data, then prospectively applying to a test set. Analyses were blinded to breast pathology. Subtype classifications were performed using a cross-validated k-nearest-neighbour (k = 3) technique, with accuracy relative to pathology assessed and receiver operator curve (AUROC) calculated. Mann-Whitney U and Kruskal-Wallis tests were used to assess raw entropy feature values. Histological subtype classifications were similar across training (n = 148 cancers) and test sets (n = 73 lesions) using all COM features (training: 75 %, AUROC = 0.816; test: 72.5 %, AUROC = 0.823). Entropy features were significantly different between lobular and ductal cancers (p < 0.001; Mann-Whitney U). IHC classifications using COM features were also similar for training and test data (training: 57.2 %, AUROC = 0.754; test: 57.0 %, AUROC = 0.750). Hormone receptor positive and negative cancers demonstrated significantly different entropy features. Entropy features alone were unable to create a robust classification model.

    Full Text Available This article focuses on issues related to the identification and investigation of the lymph node metastases with bilateral breast cancer. The presence of metastases in the lymph nodes determines the stage of the disease, and introducing a form of tumor progression, characterizes the course and prognosis for the future in a specific patient. Thus, the identification of possible morphological and immunohistochemical characteristics of the tumor tissue and their comparison with the frequency and severity of regional lymph nodes would help to solve the problem of the identification of prognostic factors and markers associated with the risk of nodal metastasis in bilateral breast cancer. This work is relevant due to the fact that the literature on this issue to date are treated ambiguously, and answers to many questions, unfortunately, no.The authors performed a morphological study of the tumor tissue from 600 patients suffering from unilateral and bilateral breast cancer. To avoid false results were studied only cases corresponding to the histological type of invasive carcinoma of non-specific type. The study found that a greater number and a greater percentage of the affected lymph node metastases were observed in patients with bilaterally synchronous tumors. The patients of this group of metastatic lymph nodes was detected more frequently in the presence of infiltrative component of three or more types of structures with the presence of these discrete groups of tumor cells, and the observed maximum degree of inflammatory infiltration of the tumor stroma. In the group of patients with unilateral breast cancer nodal metastasis often detects when triple negative molecular genetic type of the lesion, with large amounts of tumor site, in the presence of infiltrative component of three or more types of structures with the obligatory presence of these microalveolar structures and discretely spaced groups of tumor cells and the highest severity of

    International Nuclear Information System (INIS)

    Plain chest films are the most useful modality in diagnosis of primary lung cancer, but it is difficult to interpret the radiologic findings by histological types. Authors reviewed chest films of 324 cases of histologically confirmed primary lung cancer from January 1974 to April 1982 at Seoul National University. The results are as follows; 1. Incidence was most common in the 6th decade as 34.4%. Male to female sex radio was 3.8 : 1 and there was no sex difference in Adenocarcinoma. 2. Distribution of histologic types of primary lung cancers as follows; Squamous cell carcinoma 50.6%, Small cell carcinoma 22.5%, Large cell carcinoma 9.3%, Bronchogenic adeno carcinoma 10.5%, Bronchioloalveolar cell carcinoma 1.9%, Adenosquamous carcinoma 0.6%, Carcinoid tumor 0.3%, Adenoid cystic carcinoma 0.3%. 3. Radiologic findings by histologic types are follows; a) Squamous cell carcinoma commonly present as collapse (51.8%), peripheral mass (40.8%), pneumonitis (37.2%), hilar involvement (34.8%), and in single abnormality, peripheral mass (44.4%). b) Small cell carcinoma commonly present as hilar involvement (78.1%), mediastinal widening or mass (53.4%) and in single abnormality, hilar involvement (58.3%). c) Large cell carcinoma commonly present as hilar involvement (50%), pneumonia (46.7%), collapse (40%), peripheral mass (36.7%) and in single abnormality, large peripheral mass (33.3%). d) Bronchogenic adenocarcinoma commonly present as peripheral mass (44.1%), collapse (41.2%), pleural effusion (35.2%) and in single abnormality, peripheral mass (50%). e) Solitary peripheral mass commonly present as lobulation (48%) and spiculated margin (51%), but no specific findings by histologic types.

  14. Mutation analysis of breast cancer gene BRCA among breast cancer Jordanian females

    International Nuclear Information System (INIS)

    To screen mutations of the tumor suppressor breast cancer susceptibility gene 1 (BRCA1) within 3 exons among Jordanian breast cancer females. A total of 135 Jordanian breast cancer females were genetically analyzed by denaturing gradient electrophoresis (DGGE) for mutation detection in 3 BRCA1 exons (2, 11 and 20) between 2000-2002 in Al-Basheer Hospital, Amman, Jordan. Of the studied patients 50 had a family history of breast cancer, 28 had a family history of cancer other than breast cancer, and 57 had no family history of any cancer. Five germline mutations were detected among breast cancer females with a family history of breast cancers (one in exon 2 and 4 mutations in exon 11). Another germline mutation (within exon 11) was detected among breast cancer females with family history of cancer other than breast cancer, and no mutation was detected among breast cancer females with no family history of any cancer or among normal control females. Screening mutations within exon 2, exon 11 and exon 20 showed that most screened mutations were within BRCA1 exon 11 among breast cancer Jordanian families with a family history of breast cancer.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

    Objective: To detect the expressions of E-cadherin, (-catenin and (-catenin and analyze the relationship between E- cadherin-catenin adhesion complex and clinicopathological features in breast cancer. Methods: The expressions of E-cadherin, (-cadherin and (-catenin in specimens of 54 breast cancer, 21 normal breast tissues around tumor, 15 breast hyperplasia of usual type and 15 breast atypical hyperplasia were detected by immunohistochemical method. Results: In 21 normal breast tissues, E-cadherin and (-catenin were expressed on cell membrane of ductal and acinic cells, showing cellular contour and border among cells. The staining character of the three proteins in breast hyperplasia of usual type was the same as that in normal breast tissue. In breast atypical hyperplasia, the abnormal expression rates of E-cadherin, (-catenin and (-catenin were 6.7%, 13.3% and 26.7%, respectively. The total abnormal expression rate of E-cadherin-catenin complex was 33.3%. In breast cancer, the abnormal expression rates of E-cadherin, (-catenin and (-catenin were 51.9%, 63.0% and 61.1%, respectively. The total abnormal expression rate of E-cadherin-catenin complex was 88.9%. Abnormal expression of E-cadherin and (-catenin were significantly correlated with histological grade. Abnormal expressions of (-catenin and (-catenin were significantly correlated with TNM staging, axillary lymph nodes metastasis and postoperative distant metastasis. Abnormal expression of E-cadherin-catenin complex was correlated with TNM staging, histological grade and axillary lymph nodes. Abnormal expression of (-catenin was negatively correlated with expression of HER-2. COX multiple factor analysis showed that E-cadherin or (-catenin or (-catenin was not independent prognostic indicator. Conclusion: Abnormal expressions of E-cadherin, (-catenin and (-catenin frequently occur in breast cancer. Abnormal expression of E-cadherin-catenin complex is correlated with differentiation disturbance and metastasis

    Full Text Available Abstract Background Breast cancer is one of the major public health problems among women worldwide. A number of epidemiological studies have been carried out to find the role of dietary fat and the risk of breast cancer. The main objective of the present communication is to summarize the evidence from various case-control and cohort studies on the consumption of fat and its subtypes and their effect on the development of breast cancer. Methods A Pubmed search for literature on the consumption of dietary fat and risk of breast cancer published from January 1990 through December 2003 was carried out. Results Increased consumption of total fat and saturated fat were found to be positively associated with the development of breast cancer. Even though an equivocal association was observed for the consumption of total monounsaturated fatty acids (MUFA and the risk of breast cancer, there exists an inverse association in the case of oleic acid, the most abundant MUFA. A moderate inverse association between consumption of n-3 fatty acids and breast cancer risk and a moderate positive association between n-6 fatty acids and breast cancer risk were observed. Conclusion Even though all epidemiological studies do not provide a strong positive association between the consumption of certain types of dietary fat and breast cancer risk, at least a moderate association does seem to exist and this has a number of implications in view of the fact that breast cancer is an increasing public health concern.

    Directory of Open Access Journals (Sweden)

    Wasiksiri, S.

    2002-07-01

    Full Text Available Breast Cancer Susceptibility Gene1 (BRCA1 is a tumor suppressor gene for breast and ovarian cancers. The gene locates at chromosome 17q21 and encodes for 1863 amino acids protein. It is believed that BRCA1 protein is involved in many functions such as DNA repair, centrosome replication, cell cycle checkpoint and replication of other genes. More than 800 mutations have been found in the population with an increased risk of cancer incidence in their families. Germ-line mutation of BRCA1 accounts for 5-10 percent of all breast cancer cases. Epigenetic modifications also reduce the function of normal BRCA1 gene. Several methods are used for laboratory diagnosis of cancer-related mutations. The development of breast cancer in carriers at risk with BRCA1 mutations may be prevented by suitable prevention plans such as breast cancer screening, ovarian cancer screening, surgery and cancer chemotherapy.

    To evaluate factors affecting 18F-Fluorodeoxyglucose (FDG) uptake in breast cancer. For 3 years from 2006, 180 patients (mean age 48-years-old) with 187 breast cancers underwent positron emission tomography-computed tomography (PET/CT; biograph2, Siemens) at our institute and were enrolled in this study. We evaluated whether there was a correlation between the peak standardized uptake value (pSUV) of PET/CT and the histologic type of the breast cancers (n=187), grade of the invasive ductal cancers (n=142), and tumor size (n=153). The different histologic types of breast cancers include IDCs (n=156), in situ ductal carcinoma (n=10), papillary cancer (n=6), mucinous cancer (n=6), invasive lobular cancer (n=4), medullary cancer (n=3), metaplastic cancer (n=1), and neuroendocrine cancer (n=1). pSUV showed significant differences according to histologic type (p<0.005). For the available cases (n=142), IDCs were classified as grade 1 (n=25), grade 2 (n=66), and grade 3 (n=51) and correlated with the histologic grade of IDCs (rho=0.41, p<0.001). pSUV was correlated with tumor size regardless of histologic type (rho=0.525, p<0.001). In low grade IDCs, pSUV was correlated with tumor size (rho=0.48-0.86, p<0.001), but not in high grade IDCs (p>0.001). Regardless of histologic type, the larger the breast cancer, the higher the pSUV; in addition, the higher the grade of IDCs, the higher the pSUV. For the low grade IDCs, pSUV is correlated with tumor size; however, this is not the case in high grade IDCs

  11. Impact of radioguided occult lesion localization on the correct excision of malignant breast lesions. Effect of histology and tumor size

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the impact of radioguided occult lesion localization (ROLL) in the correct location and excision of malignant breast lesions, and analyze if these results are affected by the histology and tumor size. A total of 105 patients with occult breast lesions were studied. The mean age was 55 years. An intralesional dose of 18.5 MBq of 99mTc-labeled macroaggregated human albumin (AMA) was administered using stereotaxic mammography or ultrasound. Surgical resection was carried out with the help of a gammadetector probe. In the histological study, disease-free margin was defined by a distance between the tumor lesion and the surgical margin of more than 1 mm. The possible influence of tumor histology and lesion diameter with respect to free/affected margins was analyzed. Correct radiotracer placement was achieved in 100/105 of the cases (95.2%). In the remaining 5 cases (4.8%), radiotracer placement was incorrect, with 2 of them being malignant lesions that were found by macroscopic inspection, and the other 3 having benign pathology. Among the malignant lesions (44 cases), correct placement of the radiotracer was achieved in 42 cases (95.5%). Of these 42 malignant lesions, in which the ROLL was correctly performed, free surgical margins were obtained in 24 cases (57.1%), while the other 18 (42.9%) had infiltrated surgical margins. The most common histological type among the malignant lesions was invasive ductal carcinoma (71.4%). The histological types with an increased frequency of infiltration of surgical margins were invasive and microinvasive cancer (94.4%). All the affected margins were in lesions greater than 10 mm, and the highest incidence was in those between 20 and 30 mm (55.5%). In our experience, the advantages of the ROLL technique are a precise localization of malignant breast lesions (95.5%) and an increased probability of a complete excision with free margins in more than one half of them. Nevertheless, special

    Case Study Amy is a 44-year-old woman with severe autism. She lives with her sister Susan, who is her caregiver and guardian. Amy is ambulatory and able to dress and feed herself. She is a healthy individual with no other significant comorbidities. She walks daily and enjoys her sister's company. Amy's life expectancy is greater than 10 years. However, she is difficult to care for medically, as she will not allow a physical examination and strikes out when strangers try to touch her. She is nonverbal and unable to participate in decision-making. INITIAL DIAGNOSIS Amy has a history of breast cancer diagnosed 2 years ago, originally presenting as a stage I lesion (T2N0) that was palpated by her caregiver while bathing. She underwent right simple mastectomy with sentinel lymph node resection. Susan recalls that the mastectomy was a very challenging ordeal, as Amy kept pulling out IV lines, drains, and dressings. Susan felt that Amy withdrew from her after the procedure as she most likely associated Susan with the cause of the pain, making her role as caregiver more difficult. Pathology confirmed an invasive ductal carcinoma, moderately differentiated, 2.4 cm, estrogen/progesterone receptor negative, HER2/neu negative, with negative surgical margins. Two right axillary sentinel lymph nodes were negative for disease. The standard of care for a patient with these tumor features is surgery plus adjuvant chemotherapy (National Comprehensive Cancer Network [NCCN], 2012). According to the Adjuvant Online! database (2012), Amy's risk for relapse was approximately 40% without adjuvant treatment; her risk for mortality was approximately 29%. After meeting with a medical oncologist, Amy did not receive adjuvant chemotherapy. According to Susan, she was not offered the choice, and the decision was not explained to them.

    The mammalian transcriptome has recently been revealed to encompass a large number of noncoding RNAs (ncRNAs) that play a variety of important regulatory roles in gene expression and other biological processes. MicroRNAs (miRNAs), the best studied of the short noncoding RNAs (sncRNAs), have been extensively characterized with regard to their biogenesis, function and importance in tumorigenesis. Another class of sncRNAs called piwi-interacting RNAs (piRNAs) has also gained attention recently in cancer research owing to their critical role in stem cell regulation. Long noncoding RNAs (lncRNAs) of >200 nucleotides in length have recently emerged as key regulators of developmental processes, including mammary gland development. lncRNA dysregulation has also been implicated in the development of various cancers, including breast cancer. In this review, we describe and discuss the roles of sncRNAs (including miRNAs and piRNAs) and lncRNAs in the initiation and progression of breast tumorigenesis, with a focus on outlining the molecular mechanisms of oncogenic and tumor-suppressor ncRNAs. Moreover, the current and potential future applications of ncRNAs to clinical breast cancer research are also discussed, with an emphasis on ncRNA-based diagnosis, prognosis and future therapeutics.

    Objective: to study the clinical significance of Pglycoprotein (P-gp) in breast cancer. Methods: Expression of P-gp in 60 cases of breast cancer was examined by immunohistochemistry. P-gp expression and response to chemotherapy were comparatively investigated in 19 patients with metastatic breast cancer. Results: The P-gp was positive in 48.3% of the 60 cases of breast cancer. P-gp expression was not related to patients' age, menstruation status, number of axillary lymph nodes involved, clinical stage, histological type, and hormonal receptor status (P>0.05). The frequency of metastasis (62.1%) and mortality (51.7%) were higher in P-gp positive cases than in negative cases (16.1% vs 12.9%, P<0.005). The 5-year survival rate of P-gp positive cases (48.3%) was significantly lower than that of negative cases (87.1%) (P<0.05). In patients who received adjuvant chemotherapy distant metastasis occurred more frequently in the P-gp positive cases (94.7%) than in the P-gp negative cases (57.1%) (P=0.0468). More P-gp negative patients (7/9) than positive patients (1/10) were responsive to chemotherapy (P=0.0055).Conclusion: Immunohistochemical examination of P-gp expression is useful in predicting response to chemotherapy and prognosis in breast cancer patients. P-gp positivity is associated with poor prognosis.

    Full Text Available Aim: The aim was to determine serum vitamin D levels in breast cancer patients and to assess its risk association with grade and stage of the tumor. Materials and Methods: Ninety breast cancer patients and equal number of age-matched healthy females were recruited into the study by consecutive sampling over a period of 6 months for this case control study. Serum 25(OH2D levels and CT bone mineral density was done. Results: The mean age was 46±1.5 years. Age, marital status, menopausal, residential area, parda observing status, and body mass index were similar in distribution among cases and controls. The mean serum vitamin D level in the breast cancer patients was 9.3 ng/ml and in the control group was 14.9 ng/ml (P value <0.001. Vitamin D deficiency was seen in 95.6% (86 breast cancer patients and in 77% (69 of the control group (P value <0.001. Among the breast cancer patients the tumor characteristics (histology, grade, stage, and receptor status did not show any significant associations with serum levels of vitamin D. Premenopausal breast cancer females had a mean serum vitamin D level of 10.5 ng/ml and postmenopausal females had a mean value of 13.5 ng/ml (P value 0.015. Low BMD did not correlate significantly with vitamin D deficiency (P value 0.787. Conclusion: Invariably almost all patients with breast cancer were vitamin D deficient. Tumor characteristics did not show any significant associations with serum levels of vitamin D. Bone mineral density did not correlate significantly with vitamin D deficiency.

    Diet may play a role in both promoting and inhibiting human breast cancer development. In this review, nutritional risk factors such as consumption of dietary fat, meat, fiber, and alcohol, and intake of phytoestrogen, vitamin D, iron, and folate associated with breast cancer are reviewed. These nutritional factors have a variety of associations with breast cancer risk. Type of fat consumed has different effects on risk of breast cancer: consumption of meat is associated with heterocyclic amine (HCA) exposure; different types of plant fiber have various effects on breast cancer risk; alcohol consumption may increase the risk of breast cancer by producing acetaldehyde and reactive oxygen species (ROS); intake of phytoestrogen may reduce risk of breast cancer through genomic and non-genomic action; vitamin D can reduce the risk of breast cancer by inhibiting the process of cancer invasion and metastasis; intake of dietary iron may lead to oxidative stress, DNA damage, and lipid peroxidation; and lower intake of folate may be linked to a higher risk of breast cancer.

  3. Expression and prognostic significance of lysozyme in male breast cancer

    International Nuclear Information System (INIS)

    Lysozyme, one of the major protein components of human milk that is also synthesized by a significant percentage of breast carcinomas, is associated with lesions that have a favorable outcome in female breast cancer. Here we evaluate the expression and prognostic value of lysozyme in male breast cancer (MBC). Lysozyme expression was examined by immunohistochemical methods in a series of 60 MBC tissue sections and in 15 patients with gynecomastia. Staining was quantified using the HSCORE (histological score) system, which considers both the intensity and the percentage of cells staining at each intensity. Prognostic value of lysozyme was retrospectively evaluated by multivariate analysis taking into account conventional prognostic factors. Lysozyme immunostaining was negative in all cases of gynecomastia. A total of 27 of 60 MBC sections (45%) stained positively for this protein, but there were clear differences among them with regard to the intensity and percentage of stained cells. Statistical analysis showed that lysozyme HSCORE values in relation to age, tumor size, nodal status, histological grade, estrogen receptor status, metastasis and histological type did not increase the statistical significance. Univariate analysis confirmed that both nodal involvement and lysozyme values were significant predictors of short-term relapse-free survival. Multivariate analysis, according to Cox's regression model, also showed that nodal status and lysozyme levels were significant independent indicators of short-term relapse-free survival. Tumor expression of lysozyme is associated with lesions that have an unfavorable outcome in male breast cancer. This milk protein may be a new prognostic factor in patients with breast cancer

    The F box protein Skp2 is oncogenic. Skp2 and Skp2B, an isoform of Skp2 are overexpressed in breast cancer. However, little is known regarding the mechanism by which Skp2B promotes the occurrence and development of breast cancer. Here, we determined the expression and clinical outcomes of Skp2 in breast cancer samples and cell lines using breast cancer database, and investigated the role of Skp2 and Skp2B in breast cancer cell growth, apoptosis and cell cycle arrest. We obtained Skp2 is significantly overexpressed in breast cancer samples and cell lines, and high Skp2 expression positively correlated with poor prognosis of breast cancer. Both Skp2 and Skp2B could promote breast cancer cell proliferation, inhibit cell apoptosis, change the cell cycle distribution and induce the increased S phase cells and therefore induce cell proliferation in breast cancer cells. Moreover, the 2 isoforms could both suppress PIG3 expression via independent pathways in the breast cancer cells. Skp2 suppressed p53 and inhibited PIG3-induced apoptosis, while Skp2B attenuated the function of PIG3 by inhibiting PHB. Our results indicate that Skp2 and Skp2B induce breast cancer cell development and progression, making Skp2 and Skp2B potential molecular targets for breast cancer therapy. PMID:27111245

    The gross and microscopic pathology of breast cancers in women irradiated for acute postpartum mastitis was compared to the breast cancers found in the sisters of the irradiated women. In considering the lesions in the two populations, the size, location, histologic type, histologic grade, inflammatory response, lymphatic and blood vascular invasion, nipple involvement, axillary lymph node metastases, and menopausal status at the time of diagnosis were statistically indistinguishable. The only parameter that was different in the two populations was the desmoplastic response to the malignant lesion. The control population had more marked fibrosis within the cancers compared with the irradiated women

    International Nuclear Information System (INIS)

    This book results from a meeting of the ESO (European School of Oncology) Task Force on endocrine aspects of breast cancer. The contributions stem from some of the most outstanding researchers in Europe and highlight mainly methodological issues and new avenues for future research. The chapters on basic research deal primarily with experimental strategies for studying the relationship between steroid hormones, growth factors, and oncongenes. The clinically oriented chapters treat the methodology of clinical trials. Provocative questions are raised, such as: What are the pitfalls in endocrine trials? What does statistical proof mean? How can we consider a quality of life endpoint in the adjuvant setting? Two special reports deal with the controversial issues of chemoprevention in high-risk normal women and the optimization of the hormonal contribution to the adjuvant therapy of breast cancer. Topics considered included oncogenic transformations, radiotherapy, steroid hormones, cell proliferation, tamoxifen, and preventive medicine

    Caffeine has been suggested as a possible risk factor for breast cancer, potentially through its effect of facilitating the development of benign breast disease. However, coffee and tea also contain polyphenols, which exhibit anticarcinogenic properties. A hospital-based, case-control study was conducted to evaluate the role of coffee, decaffeinated coffee, and black tea in breast cancer etiology. Study participants included 1932 cases with primary, incident breast cancer and 1895 hospital controls with nonneoplastic conditions. All participants completed a comprehensive epidemiological questionnaire. Among premenopausal women, consumption of regular coffee was associated with linear declines in breast cancer risk (P for trend = 0.03); consumers of >or=4 cups/d experienced a 40% risk reduction (odds ratio = 0.62, 95% CI 0.39-0.98). No clear associations between intake of black tea or decaffeinated coffee and breast cancer risk were noted among premenopausal women, although black tea was associated with a protective effect unique to a subsample of cases with lobular histology. Among postmenopausal women, breast cancer risk was not associated with consumption of coffee, tea, or decaffeinated coffee. Results among postmenopausal women did not differ by histologic subtype. Our findings support a protective effect of coffee intake on premenopausal, but not postmenopausal breast cancer risk. Further studies are warranted to confirm these findings. PMID:16365077

    We have studied hair using fibre X-ray diffraction studies with synchrotron radiation and find that hair from breast-cancer patients has a different intermolecular structure to hair from healthy subjects. These changes are seen in all samples of scalp and pubic hair taken from women diagnosed with breast cancer. All the hair samples from women who tested positive for a mutation of the BRCA1 gene, which is associated with a higher risk of breast cancer, also show these changes. Because our results are so consistent, we propose that such hair analyses may be used as a simple, non-invasive screening method for breast cancer.

    The hypothesis has been raised that coffee consumption may increase the incidence of breast cancer, based on the report that fibrocystic breast disease, a risk factor for breast cancer, regresses after abstention from coffee and other methylxanthines. The relation between recent coffee consumption and the risk of breast cancer was evaluated in a case-control study, based on interviews conducted 1975-1982 at several mainly eastern US teaching and community hospitals. The responses of 2,651 women with newly diagnosed breast cancer were compared with those of 1,501 controls with nonmalignant conditions and 385 controls with cancers at other sites. The relative risk estimates for levels of coffee drinking up to seven or more cups daily, relative to none, approximated 1.0 with narrow 95% confidence intervals. After allowance for confounding, the relative risk estimate for drinking at least five cups a day was 1.2 (95% confidence interval, 0.9-1.6) using the noncancer controls and 1.1 (0.7-1.6) using the cancer controls. Coffee consumption was not associated with an increase in the risk of breast cancer among women with a history of fibrocystic breast disease, nor were tea or decaffeinated coffee associated with an increase in the risk of breast cancer. The results suggest that the recent consumption of coffee does not influence the incidence of breast cancer. PMID:4025289

    Full Text Available Ectopic or accessory breast tissue is most commonly located in the axilla, though it may be present anywhere along the milk line. Development is hormone dependent, similar to normal breast tissue. These lesions do not warrant any intervention unless they produce discomfort, thus their identification and distinction from other breast pathologies, both benign and malignant, is essential. We report a case with locally advanced breast cancer who presented with an ipsilateral axillary mass following surgery, radiotherapy, and chemotherapy. Subsequent evaluation with excision biopsy showed duct ectasia in axillary breast tissue and the patient was continued on hormone therapy with tamoxifen.

  4. Early-stage bilateral breast cancer treated with breast-conserving surgery and definitive irradiation: the university of Pennsylvania experience

    International Nuclear Information System (INIS)

    Purpose: To determine whether patients with early-stage bilateral breast cancer can be treated with definitive irradiation following breast-conserving surgery with acceptable survival, local control, complications, and cosmesis. Methods and Materials: During the period 1977-1992, 55 women with Stage 0, I, or II concurrent (n = 12) or sequential (n = 43) bilateral breast cancer were treated with definitive irradiation following breast-conserving surgery. The records of these 55 patients with 110 treated breasts were reviewed for tumor size, histology, pathologic axillary lymph node status, first and overall site(s) of failure, and adjuvant chemotherapy or hormonal therapy. Curves for survival, local control, and regional control were determined. Cosmetic outcome, complication rates, and matching technique were analyzed. The median total radiation dose delivered was 64 Gy (range 42-72) using tangential whole-breast irradiation followed by an electron or iridium implant boost. The tangential fields were matched with no overlap in 40 patients (73%); there was overlap on skin of up to 4 cm in 14 patients (25%); and the matching technique was unknown in 1 patient (2%). The median follow-up for the 12 women with concurrent bilateral breast cancer was 4.0 years. The median follow-up for the other 43 women with sequential cancer was 9.3 and 4.9 years, respectively, after the first and second cancers. Results: For the overall group of 55 patients, the 5- and 10-year overall survival rates were 96% and 94%, respectively, after treatment of the first cancer, and 96% and 92%, respectively, after treatment of the second cancer. The 5- and 10-year actuarial relapse-free survival rates were 90% and 75%, respectively, after treatment of the first cancer, and 83% and 72%, respectively, after treatment of the second cancer. For the 110 treated breast cancers, the 5- and 10-year actuarial local failure rates were 5% and 15%, respectively. Complication rates were: 28% breast edema, 8

    Full Text Available Breast cancer is known from ancient time,and the treatment strategy evolved as our understanding of the disease changed with time. In 460 BC Hippocrates described breast cancer as a humoral disease and presently after a lot of studies breast cancer is considered as a local disease with systemic roots. For most of the twentieth century Halsted radical mastectomy was the "established and standardized operation for cancer of the breast in all stages, early or late". New information about tumor biology and its behavior suggested that less radical surgery might be just as effective as the more extensive one. Eventually, with the use of adjuvant therapy likeradiation and systemic therapy, the extent of surgical resection in the breast and axilla got reduced further and led to an era of breast conservation. The radiation treatment of breast cancer has evolved from 2D to 3D Conformal and to accelarated partial breast irradiation, aiming to reduce normal tissue toxicity and overall treatment time. Systemic therapy in the form of hormone therapy, chemotherapy and biological agents is now a well-established modality in treatment of breast cancer. The current perspective of breast cancer management is based on the rapidly evolving and increasingly integrated study on the genetic, molecular , biochemical and cellular basis of disease. The challenge for the future is to take advantage of this knowledge for the prediction of therapeutic outcome and develop therapies and rapidly apply more novel biologic therapeutics.

From 1998 to 2002, sonography was performed on a total 7 patients (age 23 to 38 years), who were pathologically diagnosed with breast cancer during pregnancy. Six of those patients underwent mammography. Five patients underwent a breast MRI, preoperatively. The radiological findings were evaluated retrospectively. Six patients underwent surgery and 1 patient underwent a core biopsy and chemotherapy. The histological, nuclear grading and pathological staging were evaluated. The sonographic findings showed a mass with irregular shapes (n=6), irregular margins (n=6), a non-parallel orientation (n=5), complex echo patterns (n=5). Associated findings could be observed in 3 patients, including Cooper's ligament thickening (n=2), edema (n=2), skin thickening (n=1) and axillary lymphadenopathy (n=3). The sonographic findings were positive and showed masses in 6 patients. All the patients had a dense breast in mammography. The mammographic findings included masses (n=4), masses with microcalcifications (n=2), masses with axillary lymphadenopathy (n=3), calcifications alone (n=1), an asymmetric density alone (n=1), extremely dense breasts with negative findings (n=2). A breast MRI showed an irregular shaped mass (n=4) with a rim-like enhancement (n=3), linear ductal enhancement without a mass (n= 1), and the time intensity cure revealed the typical pattern and level of enhancement in the carcinoma. Sonography is a valuable tool for diagnosing pregnancy-associated breast cancer. However, mammography should be performed if there is a suspicious lesion on sonography in order to confirm the pregnancy-associated breast cancer. Mammography has a lower sensitivity during pregnancy due to the physiologic changes in the breasts. However, calcifications and associated findings are

The mammographic findings included masses (n=4), masses with microcalcifications (n=2), masses with axillary lymphadenopathy (n=3), calcifications alone (n=1), an asymmetric density alone (n=1), extremely dense breasts with negative findings (n=2). A breast MRI showed an irregular shaped mass (n=4) with a rim-like enhancement (n=3), linear ductal enhancement without a mass (n= 1), and the time intensity cure revealed the typical pattern and level of enhancement in the carcinoma. Sonography is a valuable tool for diagnosing pregnancy-associated breast cancer. However, mammography should be performed if there is a suspicious lesion on sonography in order to confirm the pregnancy-associated breast cancer. Mammography has a lower sensitivity during pregnancy due to the physiologic changes in the breasts. However, calcifications and associated findings are helpful

In the current study, we analyzed the incidence of thyroid cancer and breast cancer in 50 US states and in the District of Columbia to ascertain how often these two diseases are associated. Methods: Data on the incidence of thyroid cancer were obtained from the Centers for Disease Control and Prevention and the National Cancer Institute and data on the incidence of breast cancer were from the American Cancer Society. Data on the average number of children per family with children and mean household income were sourced from the US Bureau of the Census and prevalence of obesity by state is determined from a paper published in 2010 on state-specific obesity prevalence among US adults by the Centers for Disease Control and Prevention. Results: There was a significant association between breast and thyroid cancer (P=0.002. Since the incidence of breast cancer increases with increasing income and obesity, while decreasing with parity, multiple linear regression was performed. Breast cancer incidence was significantly related to thyroid cancer incidence (β=0.271, P=0.039, inversely related to average number of children per family with children (β=-0.271, P=0.039, unrelated to adult obesity (β=0.134, P=0.369, and significantly related to family income (β=0.642, P<0.001. Conclusion: This study identifies an association between breast and thyroid cancer. The association suggests that unexplored breast-thyroid cancer susceptibility loci exist and warrant further study.

    Background and purpose: to determine whether the blood hemoglobin concentration correlates with the prognosis of patients with early breast cancer and, if so, whether this is restricted to treatment modality. Patients and methods: data were collected retrospectively from patients with early breast cancer (T1,2 NO-2 MO) who underwent either breast-conserving surgery followed by adjuvant radiotherapy (BCS-RT; n = 96) or a modified radical mastectomy (MRM; n = 194). The effect of preoperative blood hemoglobin level, nodal status, histological grading and hormone receptor status on disease-free survival was determined for both treatment modalities using a cox regression model and visualized by kaplan-meier plots. Results: the blood hemoglobin concentration significantly correlated with disease-free survival of patients receiving BCS-RT (relative risk [RR]: 0.67 per g/dl; p = 0.007). This was independent of other known risk factors for breast cancer patients, as determined by multivariate analysis. By contrast, the blood hemoglobin level had no prognostic significance when patients were treated with MRM. Conclusion: blood hemoglobin concentration seems to affect the prognosis of patients with early breast cancer when a treatment schedule that includes radiotherapy is applied. Reduced radiosensitivity due to diminished tumor oxygenation may be the underlying cause. Confirmative trials and studies intended to elucidate the underlying mechanism are warranted. (orig.)

    A previously reported microarray data analysis by RISS algorithm on breast cancer showed over-expression of the growth factor receptor (Grb7) and it also highlighted Tweety (TTYH1) gene to be under expressed in breast cancer for the first time. Our aim was to validate the results obtained from the microarray analysis with respect to these genes. Also, the relationship between their expression and the different prognostic indicators was addressed. RNA was extracted from the breast tissue of 30 patients with primary malignant breast cancer. Control samples from the same patients were harvested at a distance of ≥5 cm from the tumour. Semi-quantitative RT-PCR analysis was done on all samples. There was a significant difference between the malignant and control tissues as regards Grb7 expression. It was significantly related to the presence of lymph node metastasis, stage and histological grade of the malignant tumours. There was a significant inverse relation between expression of Grb7 and expression of both oestrogen and progesterone receptors. Grb7 was found to be significantly related to the biological classification of breast cancer. TTYH1 was not expressed in either the malignant or the control samples. The RISS by our group algorithm developed was laboratory validated for Grb7, but not for TTYH1. The newly developed software tool needs to be improved. PMID:25182704

    On the basis of clinical observations that some women with fibrocystic breast disease experienced resolution of the disease on eliminating methylxanthines from their diet, it has been suggested that coffee intake might be related to breast carcinogenesis. The relationship between coffee (mostly expresso and mocha), decaffeinated coffee and tea intake and breast cancer risk was therefore considered, combining data from two case-control studies, conducted in Italy between 1983 and 1994. Cases were 5,984 women, below age 75, with histologically confirmed breast cancer, and controls were 5,504 women admitted to hospital for a wide spectrum of acute, non-neoplastic, non-hormone-related diseases. The odds ratios (ORs) were estimated from multiple logistic regression equations including terms for study/centre, age, education, body mass index, smoking status, total alcohol intake, age at menarche and menopause, parity and age at first birth, use of oral contraceptives, use of hormone replacement therapy, history of benign breast disease and family history of breast cancer. No relationship was observed between coffee intake and the risk of breast cancer. The multivariate ORs were 1.17 (1.03-1.33), 1.17 (1.04-1.33), 1.21 (1.06-1.37) and 0.96 (0.83-1.11) for women drinking 2 to or = 4 cups/day compared to non-drinkers. Decaffeinated coffee was consumed only by 6-7% of cases and controls and the corresponding OR was 0.84 (0.72-0.98). Tea consumption was also low and not associated with the risk of breast cancer (OR 0.94, 95% CI 0.85-1.03). No significant heterogeneity was found for coffee intake across strata of age at diagnosis, education, body mass index, smoking status, total alcohol intake, age at menarche and menopause, parity, age at first birth, ever use of oral contraceptives, hormone replacement therapy, history of benign breast disease and family history of breast cancer. Thus, this study, based on a large data set, allows us to exclude the hypothesis that coffee

  16. Bilateral breast cancer treated with breast-conserving surgery and definitive irradiation

    International Nuclear Information System (INIS)

    Objective: To assess whether patients with early stage bilateral breast cancer can be treated with definitive irradiation following breast-conserving surgery with acceptable survival, local control, complication rates, and cosmetic outcomes. Material and Methods: We reviewed 55 cases of patients with synchronous or sequential bilateral breast cancer treated with definitive irradiation following breast-conserving surgery at our institution from 1977 to 1992. Analysis of cases was limited to women who were AJCC clinical Stage 0, I, and II. The records of these 55 patients with 110 treated breasts were reviewed for tumor size, histology, AJCC stage, pathologic axillary lymph nodes status, first and overall site(s) of failure, and adjuvant chemotherapy or hormonal therapy. Analysis regarding matching technique, cosmetic outcome, and complication rate was also performed. The 5- and 10-year overall survival (OS), no evidence of disease (NED) survival, relapse-free survival (RFS), and local control rates were evaluated. Twelve women (22%) presented with synchronous bilateral carcinoma, and 43 women (78%) had sequential bilateral carcinoma. Of the 12 patients with synchronous cancer, 5 received adjuvant chemotherapy, 2 received Tamoxifen, and 1 received both adjuvant therapies. Of the 43 patients with sequential cancer, 6 received chemotherapy, 1 received Tamoxifen, and 1 received both adjuvant therapies for the first cancer treatment; seven received chemotherapy and 6 received Tamoxifen for the second cancer treatment. Results: The median age at the time of treatment of the first cancer was 56 years (range 26-86 years). For the 12 patients with synchronous cancer, the median follow-up was 48 months (range 9-164). For the 43 patients with sequential cancer, the median follow-up was 112 months (range 52-188 months) after the first cancer, and 59 months (range 11-153 months) after the second. The median dose delivered was 64 Gy (range 42-72 Gy) using a combination of

  19. The pathology of familial breast cancer: The pre-BRCA1/BRCA2 era - historical perspectives

    International Nuclear Information System (INIS)

    A proportion of breast carcinomas develop as a result of a genetic predispostion to the disease. Prior to cloning of the BRCA1 and BRCA2 genes a limited number of studies were carried out to identify specific histopathological characteristics of hereditary breast cancer. These studies are the subject of this review. The main finding was the association of the (atypical) medullary type of breast cancer with a family history; the most important caveat being that medullary breast cancer is found more frequently in young patients. In view of the frequent bilateral occurrence of lobular cancer, this histologic type is also likely to be associated with a predisposing genetic defect. Future investigations will have to test this hypothesis. In addition to mutations in the BRCA1 and BRCA2 genes, there are as yet unidentified genetic defects predisposing to breast cancer development, and histopathology may well help in identifying these genes in the future

    Full Text Available Abstract Background The overall incidence of male breast cancer is around 1% of all breast cancers and is on the rise. In this review we aim to present various aspects of male breast cancer with particular emphasis on incidence, risk factors, patho-physiology, treatment, prognostic factors, and outcome. Methods Information on all aspects of male breast cancer was gathered from available relevant literature on male breast cancer from the MEDLINE database over the past 32 years from 1975 to 2007. Various reported studies were scrutinized for emerging evidence. Incidence data were also obtained from the IARC, Cancer Mondial database. Conclusion There is a scenario of rising incidence, particularly in urban US, Canada and UK. Even though more data on risk factors is emerging about this disease, more multi-institutional efforts to pool data with large randomized trials to show treatment and survival benefits are needed to support the existing vast emerging knowledge about the disease.

  6. Local recurrences after breast-conserving treatments in breast cancer: risk factors and effect on survival

    International Nuclear Information System (INIS)

    To determine the risk factors for local and distant failure in node-negative breast cancer treated with breast-conservative surgery and radiotherapy and to determine the relationship between these two events. We retrospectively selected 908 patients who received conservative surgery and radiotherapy but no chemotherapy between 1980 and 1995, for a mode-negative breast cancer. Patients were divided in two groups according to the status of the margins of resection. All pathology specimens were reviewed. In case of negative margins, the risk factors for local recurrences picked up by the Cox model were histologic multi-focus (P=0.0076), peritumoral vessel invasion (P=0.021) and age ≥40 years (P=0.024), and in case of involved margins, negative oestrogen receptors (P=0.0012), histologic multi-focus (P=0.0028), and absence of hormonal therapy (P=0.017). The 10-year local recurrence rate was 18 % in case of negative margins and 29 % in case of involved margins, although in the latter case patients received high-dose adjuvant radiotherapy. Accordingly, the 10-year distant failure rates were 16 % and 27 %, respectively. Many arguments suggest that local and distant failures are closely related. Patients with histologic multi-focus or positive margins are at high risk of local failure and then of distant failure, and require a more aggressive initial treatment. (author)

  7. Microcalcifications of the Breast: How Does Radiologic Classification Correlate with Histology?

    International Nuclear Information System (INIS)

    Purpose: Tassess the correlation between the pre-biopsy classification of microcalcifications and the underlying histology. Material and Methods: Using the morphology and distribution patterns according to the Breast Imaging-Reporting and Data System (BI-RADS) lexicon, the microcalcifications of 199 lesions in 163 consecutive patients scheduled to underg11 G vacuum core biopsy were classified within the BI-RADS categories. The correlation between BI-RADS assessment categories 3, 4, and 5 and the final histological results was statistically evaluated with the χ-2 test. The diagnostic indices were calculated. Results: The prospectively classified BI-RADS 3/4/5 findings revealed a malignant histology in 5.9%/17.6%/90.9% of all lesions, respectively. The relationship between BI-RADS categories 3, 4, and 5 and histology was statistically highly significant ( P <0.0001). The sensitivity, specificity, positive and negative predictive values were 95.7%/21.2%/37.8%/94.3%, respectively. Conclusion: The BI-RADS lexicon describes microcalcifications of the breast and provides diagnostic categories that lead to standardized biopsy recommendations. Nevertheless, how to link description to classification of microcalcifications is still a difficult diagnostic task. The evaluation of microcalcifications as proposed in this article may help to set standards in the clinical routine and in the comparability of scientific data

    Breast cancer is one of the most common malignancies in women.The post-operative recurrence and metastasis are the leading causes of breast cancer-related mortality.In this study,we tried to explore the role of circulating tumor cell (CTC) detection combination PET/CT technology evaluating the prognosis and treatment response of patients with breast cancer; meanwhile,we attempted to assess the concept of "biological complete remission" (bCR) in this regard.A 56-year-old patient with breast cancer (T2N1M1,stage Ⅳ left breast cancer,with metastasis to axillary lymph nodes and lungs) received 6 cycles of salvage treatment with albumin-bound paclitaxel plus capecitabine and trastuzumab.Then,she underwent CTC detection and PET/CT for efficacy evaluation.CTC detection combination PET/CT is useful for the evaluation of the biological efficacy of therapies for breast cancer.The bCR of the patient appeared earlier than the conventional clinical imaging complete remission and promised the histological (pathological) complete remission.The integrated application of the concepts including bCR,imageological CR,and histological CR can achieve the early and accurate assessment of biological therapeutic reponse and prognosis of breast cancer.

    Full Text Available Panagiotis Apostolou, Maria Toloudi, Ioannis Papasotiriou Research and Development Department, Research Genetic Cancer Centre Ltd, Florina, Greece Abstract: Breast cancer is the most frequent type of cancer in women. Great progress has been made in its treatment but relapse is common. One hypothesis to account for the high recurrence rates is the presence of cancer stem cells (CSCs, which have the ability to self-renew and differentiate into multiple malignant cell types. This study aimed to determine genes that are expressed in breast cancer and breast CSCs and to investigate their correlation with stemness. RNA was extracted from established breast cancer cell lines and from CSCs derived from five different breast cancer patients. DNA microarray analysis was performed and any upregulated genes were also studied in other cancer types, including colorectal and lung cancer. For genes that were expressed only in breast cancer, knockdown-based experiments were performed. Finally, the gene expression levels of stemness transcription factors were measured. The outcome of the analysis indicated a group of genes that were aberrantly expressed mainly in breast cancer cells with stemness properties. Knockdown experiments confirmed the impact of several of these on NANOG, OCT3/4, and SOX2 transcription factors. It seems that several genes that are not directly related with hormone metabolism and basic signal transduction pathways might have an important role in relapse and disease progression and, thus, can be targeted for new treatment approaches for breast cancer.

  14. Correlation of contrast enhanced power Doppler sonographic findings with Histologic microvessel density in the breast mass

    International Nuclear Information System (INIS)

    To compare the pre-and postenhanced power Doppler sonographic (PDS) findings in malignant and benign breast masses and to correlate power Doppler area (PDA) and histologic microvessel density (MVD). Forty-seven women with breast masses (27 malignant and 20 benign) underwent PDS before and after an injection of microbubble contrast agent (Levovist) for five minutes. Using computer-assisted quantification, intratumoral % PDA was calculated. Microvessel density was counted on the digitized image of slides stained with anti CD31 moonclonal antibody. The statistical analysis was performed using t-test to determine the difference of % PDA between malignant and benign masses and between 0.05). MVD was well correlated with % PDA on post-enhancement PDS (r=0.69), and a stronger correlation was seen in malignant masses (r=0.71). Contrast-enhanced PDS is superior in demonstrating the difference of vascularity between malignant and benign breast masses. % PDA after contrast-enhancement exhibited a statistically significant correlation and benign breast masses. %PDA after contrast-enhancement exhibited a statistically significant correlation with histologic MVD.

    The makeup of nipple-areolar skin, in terms of its melanin and melanocyte content has not previously been established. This histological information is required if pigmentation of the reconstructed nipple-areola is to be successful in post-mastectomy breast reconstruction. We describe examination of 200 parallel sections of nipple-areolar skin of 20 women using histochemical (Masson-Fontana) and immunohistochemical (Mel-5) techniques, evaluated using quantitative image analysis. The amount of melanin present per length of basement membrane was 2.14 times higher in areolar skin than breast skin. The ratio of melanocytes to keratinocytes was 1:9.7 in areolar skin vs. 1:14.7 in breast skin. We also describe a cell culture and skin construct method using autologous human serum without toxic growth promoting additives, which could be used in the clinical setting of nipple-areolar reconstruction.

Interstitial implantation may also be used as a primary form of treatment. A report on 35 patients is presented, 25 of whom underwent a curative schedule for T1-2, N0-1 tumors. 10 patients were treated individually. The aesthetic results are very pleasing. There were no severe complications and no early local recurrences. The interpretation of the results can be only in the form of trends because of the short follow-up time of 1 year. (Author)

    Full Text Available Abstract Background Prostate cancer is the single most prevalent cancer in US men whose gold standard of diagnosis is histologic assessment of biopsies. Manual assessment of stained tissue of all biopsies limits speed and accuracy in clinical practice and research of prostate cancer diagnosis. We sought to develop a fully-automated multimodal microscopy method to distinguish cancerous from non-cancerous tissue samples. Methods We recorded chemical data from an unstained tissue microarray (TMA using Fourier transform infrared (FT-IR spectroscopic imaging. Using pattern recognition, we identified epithelial cells without user input. We fused the cell type information with the corresponding stained images commonly used in clinical practice. Extracted morphological features, optimized by two-stage feature selection method using a minimum-redundancy-maximal-relevance (mRMR criterion and sequential floating forward selection (SFFS, were applied to classify tissue samples as cancer or non-cancer. Results We achieved high accuracy (area under ROC curve (AUC >0.97 in cross-validations on each of two data sets that were stained under different conditions. When the classifier was trained on one data set and tested on the other data set, an AUC value of ~0.95 was observed. In the absence of IR data, the performance of the same classification system dropped for both data sets and between data sets. Conclusions We were able to achieve very effective fusion of the information from two different images that provide very different types of data with different characteristics. The method is entirely transparent to a user and does not involve any adjustment or decision-making based on spectral data. By combining the IR and optical data, we achieved high accurate classification.

  20. Value of breast imaging reporting and data system in Chinese breast cancer screening

    International Nuclear Information System (INIS)

    Objective: To study the value of breast imaging reporting and data system (BI-RADS) in Chinese breast cancer screening. Methods: A total number of 3483 women participated in breast cancer screening with mammography in Hexi district in Tianjin from August to December 2009, which was organized by ministry of public health. BI-RADS assessment categories and recommendations were compared with histological findings. The precision, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results: Among 3483 screening mammography cases, 267 were almost entirely fat breast, 1245 were scattered fibroglandular, 1890 were dense and 81 extremely dense. There were 1011 patients (29.0%) with category 1, 1741 (50.0%) with category 2, 383 (11.0%) with category 3, 59 patients (1.7%) with category 4 and 16 (0.5%) with category 5 according to BI-RADS assessment categories. Totally, 71 women with 77 lesions were confirmed by histological examinations. There were 29 malignant and 48 benign lesions. The diagnostic precision, sensitivity, specificity of' BI-RADS were 63.6% (49/77), 93.1% (27/29) and 45.8% (22/48). The general PPV of BI-RADS was 50.9% (27/53). The PPV of categories 0.4, 5 were 25.0% (1/4), 36.4% (12/33) and 87.5% (14/16). The NPV of categories 2 and 3 were 90.9% (10/11), 100.0% (12/12). Conclusions: BI-RADS is of much value in assessing the breast malignancy. It is applicable in Chinese breast cancer screening. (authors)

  1. Breast cancer in atomic bomb survivors

    International Nuclear Information System (INIS)

    Thirty eight years after the atomic bombings, studies of the Radiation Effects Research Foundation (RERF) on the extended Life Span Study (LSS) sample have continued to provide important information on radiation carcinogenesis. The third breast cancer survey among this sample revealed 564 cases during the period 1950-80, of which 412 were reviewed microscopically. The following statements reflect the conclusions from the current investigation; 1) the relationship between radiation dose and breast cancer incidence was consistent with linearity and did not differ markedly between the Hiroshima and Nagasaki survivors, 2) a dose-related breast cancer risk was observed among women who were in their first decade of life at the time of exposure, 3) the relative risk of radiationinduced breast cancer decreased with increasing age at exposure, 4) the pattern over time of age-specific breast cancer incidence is similar for exposed and control women (that is, exposed women have more breast cancer than control women but the excess risk closely follows normal risk as expressed by age-specific population rates), and 5) radiation-induced breast cancer appears to be morphologically similar to other breast cancer

    Full Text Available Abstract Background This exploratory prospective study evaluated women's responses to questions that asked them to describe how their body image and sexual functioning had changed since their breast cancer diagnosis to treatment. Methods A questionnaire concerning body image scale and various sexual problems experienced after diagnosis and treatment was anonymously completed by 120 women in the outpatient clinic of our hospital's Division of medical Oncology. To be eligible, subjects had to be sexually active and had histology proven breast cancer. They also had to have received treatment for breast cancer. Results 100% of participants have never spoken with their doctor about this subject. 84% of the participants continued sexual activity after treatment, but there was an increase in the incidence of sexual functioning problems which resulted in a slight reduction in the quality of their sex lives. 65% of the women experienced dyspareunia followed by lubrication difficulties (54% and the absence or reduction of sexual desire (48% and 64%, respectively while, 37% had lack of satisfaction (37%. Female orgasmic disorder and brief intercourse and arousal were reported respectively by 40% and 38% of the subjects. The sexual dysfunctions were absent before diagnosis and management of breast cancer in 91.5% subjects and of these 100% subjects complained of a deterioration of the symptomatology after the various treatments. 90% of the dysfunctions were observed after chemotherapy, 9% after surgery and 3% after radiotherapy; none of the subjects indicated the onset of dysfunctions to have been associated with hormonotherapy. 100% expressed not having received sufficient information about how the disease and treatment (including surgery might affect their sexual life. Conclusion Breast cancer and its treatment may result in significant difficulties with sexual functioning and sexual life. Addressing these problems is essential to improve the quality of

    2016-06-30

    Breast cancer is the third most common illness in the world and the most frequent malignant disease with women. Cytotoxic therapy is connected to significant psychiatric adverse effects, and the appearance of depressive symptoms is the most common. The main goal is determining the degree of depression with breast cancer patients in the oncology ward of the University Clinical Hospital in Niš and its connection to their marital status, age, level of education, economic status and the number of therapy cycles. This research is a prospective study. The statistical data analysis included measures of descriptive and analytical statistics. The presence of depressive symptoms of different intensity was showed in 76.00% of the interviewees in group I, and the second included 77.4%. The frequency distributions show that 27.084% interviewees from the first group showed signs of depressive symptoms, while the second included 25%. The intensity of these symptoms categorizes them into the group of moderate to significantly expressed depressive states, so they require therapeutic treatment. Depression is significantly more often recorded with cancer patients receiving cytotoxic therapy; mild depression is the most common, followed by moderate and severe depression. PMID:27138829

    Directory of Open Access Journals (Sweden)

    Martin Oeggerli

    Full Text Available KCNMA1 encodes the α-subunit of the large conductance, voltage and Ca(2+-activated (BK potassium channel and has been reported as a target gene of genomic amplification at 10q22 in prostate cancer. To investigate the prevalence of the amplification in other human cancers, the copy number of KCNMA1 was analyzed by fluorescence-in-situ-hybridization (FISH in 2,445 tumors across 118 different tumor types. Amplification of KCNMA1 was restricted to a small but distinct fraction of breast, ovarian and endometrial cancer with the highest prevalence in invasive ductal breast cancers and serous carcinoma of ovary and endometrium (3-7%. We performed an extensive analysis on breast cancer tissue microarrays (TMA of 1,200 tumors linked to prognosis. KCNMA1 amplification was significantly associated with high tumor stage, high grade, high tumor cell proliferation, and poor prognosis. Immunofluorescence revealed moderate or strong KCNMA1 protein expression in 8 out of 9 human breast cancers and in the breast cancer cell line MFM223. KCNMA1-function in breast cancer cell lines was confirmed by whole-cell patch clamp recordings and proliferation assays, using siRNA-knockdown, BK channel activators such as 17ß-estradiol and the BK-channel blocker paxilline. Our findings revealed that enhanced expression of KCNMA1 correlates with and contributes to high proliferation rate and malignancy of breast cancer.

  18. Estrogen sulfotransferases in breast and endometrial cancers.

    Science.gov (United States)

    Pasqualini, Jorge Raul

    2009-02-01

    Estrogen sulfotransferase is significantly more active in the normal breast cell (e.g., Human 7) than in the cancer cell (e.g., MCF-7). The data suggest that in breast cancer sulfoconjugated activity is carried out by another enzyme, the SULT1A, which acts at high concentration of the substrates. In breast cancer cells sulfotransferase (SULT) activity can be stimulated by various progestins: medrogestone, promegestone, and nomegestrol acetate, as well as by tibolone and its metabolites. SULT activities can also be controlled by other substances including phytoestrogens, celecoxib, flavonoids (e.g., quercetin, resveratrol), and isoflavones. SULT expression was localized in breast cancer cells, which can be stimulated by promegestone and correlated with the increase of the enzyme activity. The estrogen sulfotransferase (SULT1E1), which acts at nanomolar concentration of estradiol, can inactivate most of this hormone present in the normal breast; however, in the breast cancer cells, the sulfotransferase denoted as SULT1A1 is mainly present, and this acts at micromolar concentrations of E(2). A correlation was postulated among breast cancer cell proliferation, the effect of various progestins, and sulfotransferase stimulation. In conclusion, it is suggested that factors involved in the stimulation of the estrogen sulfotransferases could provide new possibilities for the treatment of patients with hormone-dependent breast and endometrial cancers.

    Clinico-radiobiological characteristics of radiotherapy for relapsed breast cancer were studied. Adequate choice of tissue mass to be exposed appeared much more important than any change in focal dose within 50-80 Gy, to achieve higher frequency of locoregional therapeutic effect. However, recurrent tumors more than 3 large lower radiosensitivity involving a sharp rise in the likelihood of dissemination. Radiotherapy for primary tumor did not affect the radiosensitivity of recurrent malignancies but slowed down the rate of its growth. Also, it might promote the dissemination acceleration

  20. Breast implants following mastectomy in women with early-stage breast cancer: prevalence and impact on survival

    International Nuclear Information System (INIS)

    Few studies have examined the effect of breast implants after mastectomy on long-term survival in breast cancer patients, despite growing public health concern over potential long-term adverse health effects. We analyzed data from the Surveillance, Epidemiology and End Results Breast Implant Surveillance Study conducted in San Francisco–Oakland, in Seattle–Puget Sound, and in Iowa. This population-based, retrospective cohort included women younger than 65 years when diagnosed with early or unstaged first primary breast cancer between 1983 and 1989, treated with mastectomy. The women were followed for a median of 12.4 years (n = 4968). Breast implant usage was validated by medical record review. Cox proportional hazards models were used to estimate hazard rate ratios for survival time until death due to breast cancer or other causes for women with and without breast implants, adjusted for relevant patient and tumor characteristics. Twenty percent of cases received postmastectomy breast implants, with silicone gel-filled implants comprising the most common type. Patients with implants were younger and more likely to have in situ disease than patients not receiving implants. Risks of breast cancer mortality (hazard ratio, 0.54; 95% confidence interval, 0.43–0.67) and nonbreast cancer mortality (hazard ratio, 0.59; 95% confidence interval, 0.41–0.85) were lower in patients with implants than in those patients without implants, following adjustment for age and year of diagnosis, race/ethnicity, stage, tumor grade, histology, and radiation therapy. Implant type did not appear to influence long-term survival. In a large, population-representative sample, breast implants following mastectomy do not appear to confer any survival disadvantage following early-stage breast cancer in women younger than 65 years old

  5. Radial scars detected mammographically in a breast cancer screening programme

    International Nuclear Information System (INIS)

    Radial scars are getting more and more common since implementation of mammography as diagnostic tool in screening women for breast cancer. At Karolinska Hospital, 18987 asymptomatic women, aged 50-69, were screened for breast cancer through mammography during August 1989-May 1991. A total of 735 (3.87%) were recalled for additional views after initial mammograms and 463 (2.44%) were assessed with help of cytology. In all 175 women (0.92%) were selected for surgery and 146 (0.77%) had histologically verified cancers. The remaining 29 (0.15%) had non- malignant lesions of which 11 (0.06%) were radial scars. All radial scars were diagnosed on mammograms and later confirmed with histology. The radiologic characteristics were found to be a) rather thick and long radiating structures accompanied by radiolucent linear structures parallel to some of the spicules, b) absence of calcifications, c) radiolucent areas in the body of the lesion, d) an average mean size of 6 mm and e) changing image in different views. Most of the lesions, 73% (8/11), were in moderately dense breasts and there was no specific relation to the right or left breast. A majority of radial scars, 64% (7/11), were found in the upper outer quadrants, 3/11 in the lower outer quadrants and 1/11 in the lower inner quadrant. Literature shows that histology uses many synonyms for radial scars and therefore team work between radiologists and pathologists is suggested for better conformity of the diagnosis.

  6. Total antioxidant status in women with breast cancer

    International Nuclear Information System (INIS)

    Objective: To measure the concentration of total antioxidant status (TAS) in women with breast cancer. Methodology: This is a case control study conducted in Al-Salam Hospital and Department of Pharmacology in Mosul Medical College. Twenty women having histologically confirmed breast cancer and twenty age-matched healthy volunteer women participated in the study. Serum total antioxidant status (TAS) was measured in both groups. Results: Mean TAS of the patient group (0.91 +- 0.32 mmol/l) was significantly lower (P<0.001) than that of the control group (1.82 +- 0.14 mmol/l). Conclusion: The present study demonstrated that women with breast cancer have a low level of TAS as compared to those of healthy women. It further emphasizes the growing concern that oxidative damage may occur in those patients that exhaust the antioxidant defense of the body leading to a low levels of TAS. Administration of antioxidant supplements such as a combination of vitamins A, C and E are necessary in women at high risk of developing breast cancer or after surgery or with anticancer drugs.

    Full Text Available Purpose: The aim of this study is twofold – on the one hand, to analyze the relationship between incidence of breast cancer, income per capita and medical equipment across countries; after that, the study here discusses the drivers of the incidence of breast cancer across countries in order to pinpoint differences and similarities. Methods: The indicators used are incidence of breast cancer based on Age-standardized rate (ASW; Gross domestic product (GDP per capita by purchasing power parity (current international $; computed tomography (CT for cancer diagnosis. Data include 52 countries. The statistical analysis is carried out by correlation, ANOVA and an econometric modeling based on a multiple regression model of the breast cancer incidence on two explanatory variables. Results: Partial correlation is higher: rbreast cancer, GDP  CT=60.3% (sign.0.00. The estimated relationship shows an expected incidence of breast cancer increase of approximately 0.05% for a GDP increase of 1% and an expected incidence of breast cancer increase of approximately 3.23% for a CT increase of 1%. ANOVA confirms that incidence of breast cancer is higher across richer countries, ceteris paribus.Conclusions: Empirical evidence shows that the breast cancer tends to be higher across richer countries, measured by GDP per capita and number of Computed Tomography. The main determinants of these findings can be due to several socio-economic factors, mainly localized in richer countries. In addition, this research may provide an alternative interpretation to the theory of Oh et al. (2010 on the influence of latitude on breast cancer, focusing on socio-economic factors rather than biologic root causes.

  8. Screening for breast cancer post reduction mammoplasty

    International Nuclear Information System (INIS)

    Aim: To investigate whether remodelling of the breast after breast reduction surgery has an effect on mammographic cancer detection. Methods and materials: For women who attended population-based screening between January 1998 to December 2007, data were extracted on their age, history of previous breast reduction, and the result of screening (recall for further assessment, cancer, or no cancer). The number of cancers detected, recalls per 1000 screens and the characteristics of the cancers detected in the two groups was compared. Results: In total 244,147 women with 736,219 screening episodes were reviewed. In the 4743 women who had a breast reduction, 51 breast cancers were detected [age standardized rate (ASR) of 4.28 per 1000 screening episodes; 95% CI 3.11-5.46], compared with 4342 breast cancers in 239 404 women screened in the non-reduction group (ASR of 5.99 per 1000 screening episodes; 95% CI 5.81-6.16). There were fewer cancers in the breast reduction group with a relative risk of 0.71. There was no significant difference in the rate of recall between the two groups, with a crude recall rate of 46.1 per 1000 screening episodes post-breast reduction compared with 50.7 per 1000 screening episodes for women without breast reduction. There was no significant difference in the pathological type or location of the cancer between the two groups of women. Conclusion: Postoperative breast changes following reduction mammoplasty do not significantly hinder analysis of the screening mammogram.

  9. The history of breast cancer advocacy.

    Science.gov (United States)

    Braun, Susan

    2003-01-01

    There have been four key steps in the advent of breast cancer advocacy: priming the market, engaging consumers, establishing political advocacy, and taking the advocacy mainstream. Breast cancer was surrounded by secrecy until the 1980s, when brave individuals such as former First Ladies Betty Ford and Nancy Reagan, and founder of the Susan G. Komen Foundation, Nancy Brinker (Susan Komen's sister), began speaking publicly about the personal impact of the disease, which increased awareness of breast cancer and made it more acceptable to talk about it openly. At the same time, statistics about breast cancer were presented in new ways that the public could understand. Public health advocates played a key role in the second step, engaging consumers, when they established guidelines in the 1980s that encouraged women to perform breast self-examinations (BSEs) and have screening mammograms and clinical breast examinations (CBEs). Other events that helped engage consumers were increased media coverage of breast cancer issues, the founding of the Komen Race for the Cure in 1983, and the establishment of other programs that both educated the public and raised funds. Funds from these efforts enabled advocates to hold educational forums and produce educational materials in different media and tailored to different audiences and to become active in the funding of research. The third step, political action, became possible when breast cancer advocates joined together in the 1980s and 1990s to work toward legislative, regulatory, and funding changes, such as passage of the Mammography Quality Standards Act and increased funding for the National Cancer Institute. These efforts contributed to a more than quadrupling of federal funding for breast cancer research in the 1990s. Going mainstream, the final step in the advocacy process, entailed establishing a solid base of support to ensure that the message about breast cancer stays strong and fresh. This has been achieved by engaging

There are different therapeutic methods for treatment of breast cancer and the choice of treatment depends on the stage of the disease as well as its type and characteristics. Therapeutic methods include surgery, radiotherapy, and systemic therapies, each consisting of a variety of techniques. The two main surgical techniques are lumpectomy and mastectomy. The main systemic methods are biological therapy (immunotherapy), hormone therapy, and chemotherapy. Radiotherapy is mainly categorized into external-beam radiotherapy and brachytherapy. In this paper, we present a brief review of the different types of breast cancer and their treatments using conventional and modern radiotherapy methods, as well as the treatment efficacy and side effects of breast radiotherapy.

  11. Aetio-pathogenesis of breast cancer

    2013-01-01

    Full Text Available This is a literature review on the aetiology and pathogenesis of breast cancer, which is the most common cancer worldwide, and the second leading cause of cancer death, especially in Western countries. Several aetiological factors have been implicated in its pathogenesis, and include age, genetics, family history, diet, alcohol, obesity, lifestyle, physical inactivity, as well as endocrine factors. These factors act separately or together in the causation of breast cancer. More recently, triple negative breast cancer has been described in certain categories of patients and is associated with poorer prognosis and earlier recurrence compared with the conventional breast cancer. Therefore, adequate knowledge of these factors is important in identifying high risk groups and individuals, which will help in screening, early detection and follow-up. This will help to decrease the morbidity and mortality from this life-threatening disease.

    International Nuclear Information System (INIS)

    Exploratory study was conducted, observational (cohort study), application, in order to evaluate the performance of advanced breast cancer in Clinical and Surgical Teaching Hospital 'Jose Ramon Lopez Tabrane' during the period from January 2005 to December 2007. Our main objective was to understand the behavior of advanced cancer breast cancer in our midst in the aforementioned period. Our sample consisted of 44 patients, which was applied to the study Statistical analysis for the different variables used, expressing results in tables. The 4th and 5th decade of life, and the white skin color were variable representative in our sample. The right breast and upper quadrant outside were the most frequent sites of breast cancer. More than half of the patients had a tumor larger than 5 cm and metastatic nodes. Madden mastectomy was the most frequently used providing the greatest number of complications. We recommend the importance of breast self-examination and diagnosis preclinical use of mammography. (Author)

  15. Epithelial-Mesenchymal Transition and Breast Cancer

    2016-01-01

    Full Text Available Breast cancer is the most common cancer in women and distant site metastasis is the main cause of death in breast cancer patients. There is increasing evidence supporting the role of epithelial-mesenchymal transition (EMT in tumor cell progression, invasion, and metastasis. During the process of EMT, epithelial cancer cells acquire molecular alternations that facilitate the loss of epithelial features and gain of mesenchymal phenotype. Such transformation promotes cancer cell migration and invasion. Moreover, emerging evidence suggests that EMT is associated with the increased enrichment of cancer stem-like cells (CSCs and these CSCs display mesenchymal characteristics that are resistant to chemotherapy and target therapy. However, the clinical relevance of EMT in human cancer is still under debate. This review will provide an overview of current evidence of EMT from studies using clinical human breast cancer tissues and its associated challenges.

  17. Breast reconstruction in conserving breast cancer surgery

    International Nuclear Information System (INIS)

    Breast conserving treatment (BCT) combined with radiotherapy have provedthe test of time as a sound oncological operation regarding survival andlocal recurrence. Successful BCT is a balance between adequate surgery andmaintaining the breast's appearance. Unsatisfactory outcome reaches 20-30% instandard techniques of BCD. Concepts described to widen the spectrum of BCT,have made an improvement of cosmetic outcome and facilitated a liberal safetymargin. Volume displacement techniques, such as glandular flap, mammoplasty,donut mastopexy and batwing mastopexy proved useful in large breasts andvolume replacement, such as latissimus dorsi flap and local flaps are ofgreat advantage to replace defects in small and medium sized breasts. Some ofthese techniques are simple, but comprehensive knowledge and training arerequired for sophisticated ones. The objectives of this article are to shedlight on different techniques adopted by surgeons to perform BCT inconjunction with various oncoplastic techniques and to discuss the factorsthat influence their applications to achieve best oncological and aestheticoutcome.

    2013-11-01

    Eribulin mesylate is a synthetic analog of halichondrin B (a polyether macrolide isolated from a marine sponge). It is a nontaxane microtubule dynamics inhibitor with a novel mechanism of action. It is the first drug that has demonstrated an improvement in overall survival as a single agent compared with the physician's choice of currently available treatments in locally advanced or metastatic breast cancer, previously treated with anthracyclines and taxanes. It has shown a good manageable tolerability profile. This drug has been approved by the US FDA and by the EMA for patients with locally advanced or metastatic breast cancer who have received at least two chemotherapeutic regimens for advanced/metastatic disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting unless patients were not suitable for these treatments. The aim of this article is to describe the mechanism of action, pharmacokinetics, pharmacodynamics and the most relevant clinical trials in the development of this drug. PMID:24161305

  19. Adoption of Hypofractionated Whole-Breast Irradiation for Early-Stage Breast Cancer: A National Cancer Data Base Analysis

    International Nuclear Information System (INIS)

    Purpose: To evaluate the relationship of patient, hospital, and cancer characteristics with the adoption of hypofractionation in a national sample of patients diagnosed with early-stage breast cancer. Methods and Materials: We performed a retrospective study of breast cancer patients in the National Cancer Data Base from 2004-2011 who were treated with radiation therapy and met eligibility criteria for hypofractionation. We used logistic regression to identify factors associated with receipt of hypofractionation (vs conventional fractionation). Results: We identified 13,271 women (11.7%) and 99,996 women (88.3%) with early-stage breast cancer who were treated with hypofractionation and conventional fractionation, respectively. The use of hypofractionation increased significantly, with 5.4% of patients receiving it in 2004 compared with 22.8% in 2011 (P<.001 for trend). Patients living ≥50 miles from the cancer reporting facility had increased odds of receiving hypofractionation (odds ratio 1.57 [95% confidence interval 1.44-1.72], P<.001). Adoption of hypofractionation was associated with treatment at an academic center (P<.001) and living in an area with high median income (P<.001). Hypofractionation was less likely to be used in patients with high-risk disease, such as increased tumor size (P<.001) or poorly differentiated histologic grade (P<.001). Conclusions: The use of hypofractionation is rising and is associated with increased travel distance and treatment at an academic center. Further adoption of hypofractionation may be tempered by both clinical and nonclinical concerns

  3. Radiation as a cause of breast cancer

    International Nuclear Information System (INIS)

    The possible role of radiation as a factor in the causation of breast cancer was investigated. Some variables said to be associated with a high risk of breast cancer include genetic factors, pre-existing breast disease, artificial menopause, family history of breast cancer, failure to breast feed, older than usual age at time of first pregnancy, high socioeconomic status, specific blood groups, fatty diet, obesity, and hormonal imbalances. To this list we must add ionizing radiation as an additional and serious risk factor in the causation of breast cancer. Among the irradiated groups which have an increase in the incidence of cancer of the breast are: tuberculous women subjected to repeated fluoroscopy; women who received localized x-ray treatments for acute post-partum mastitis; atom-bomb survivors; other x-ray exposures involving the breast, including irradiation in children and in experimental animals; and women who were treated with x rays for acne or hirsuitism. The dose of radiation received by the survivors of the atom bomb who subsequently developed cancer of the breast ranged from 80 to 800 rads, the tuberculous women who were fluoroscoped received an estimated 50 to 6,000 rads, the women who were treated for mastitis probably were exposed to 30 to 700 rads, and the patients with acne received 100 to 6,000 rads. These imprecise estimates are compared with mammographic doses in the range of 10s of rads to the breast at each examination, an imprecise estimate depending on technique and equipment. However imprecise these estimates may be, it is apparent that younger women are more likely than older women to develop cancer from exposure to radiation. It is pointed out that the American Cancer Society advises that women under 35 years should have mammography only for medical indication, not for so-called screening

    A functional DNA repair system has been identified as important in the prevention of tumour development. Previous studies have hypothesized that common polymorphisms in DNA repair genes could play a role in breast cancer risk and also identified the potential for interactions between these polymorphisms and established breast cancer risk factors such as physical activity. Associations with breast cancer risk for 99 single nucleotide polymorphisms (SNPs) from genes in ten DNA repair pathways were examined in a case-control study including both Europeans (644 cases, 809 controls) and East Asians (299 cases, 160 controls). Odds ratios in both additive and dominant genetic models were calculated separately for participants of European and East Asian ancestry using multivariate logistic regression. The impact of multiple comparisons was assessed by correcting for the false discovery rate within each DNA repair pathway. Interactions between several breast cancer risk factors and DNA repair SNPs were also evaluated. One SNP (rs3213282) in the gene XRCC1 was associated with an increased risk of breast cancer in the dominant model of inheritance following adjustment for the false discovery rate (P breast cancer risk or their modification by breast cancer risk factors were observed.

  8. Serum soluble ST2 is associated with ER-positive breast cancer

    International Nuclear Information System (INIS)

    ST2, a member of the interleukin (IL)-1receptor family, regulates Th1/Th2 immune responses in autoimmune and inflammatory conditions. However, the role of ST2 signaling in tumor growth and metastasis of breast cancers has not been investigated. This study investigated the possible role of soluble ST2 (sST2) in breast cancer. The serum levels of IL-33, sST2, and vascular endothelial growth factor (VEGF) in 150 breast cancer patients and 90 healthy women were measured by enzyme-linked immunosorbent assay. Estrogen receptor(ER), progesterone receptor, human epithelial receptor (HER)-2, and cell cycle regulated protein Ki-67 were measured. Clinical stage, tumor size, lymph node metastasis, and histological type were also recorded. The serum levels of sST2, IL-33, and VEGF were significantly higher in breast cancer patients than in the control group (P < 0.05, each). Serum sST2 levels in ER-positive breast cancer patients were significantly associated with age, histological type, clinical stage, tumor size, and Ki-67 status (P < 0.05, each). Moreover, the serum levels of IL-33 and sST2 in breast cancers significantly correlated with VEGF levels (IL-33: r = 0.375, P < 0.0001; sST2: r = 0.164, P = 0.045). Serum levels of sST2, IL-33, and VEGF decreased after modified radical mastectomy in ER-positive breast cancers. Serum levels of IL-33, sST2, and VEGF and clinicopathological factors were not significantly correlated with disease-free survival and overall survival of ER-positive breast cancer women during follow-up. Serum sST2 levels in ER-positive breast cancer patients are significantly associated with factors that indicate poor prognosis

    Common variation on 14q24.1, close to RAD51B, has been associated with breast cancer: rs999737 and rs2588809 with the risk of female breast cancer and rs1314913 with the risk of male breast cancer. The aim of this study was to investigate the role of RAD51B variants in breast cancer predisposition, particularly in the context of familial breast cancer in Finland. We sequenced the coding region of RAD51B in 168 Finnish breast cancer patients from the Helsinki region for identification of possible recurrent founder mutations. In addition, we studied the known rs999737, rs2588809, and rs1314913 SNPs and RAD51B haplotypes in 44,791 breast cancer cases and 43,583 controls from 40 studies participating in the Breast Cancer Association Consortium (BCAC) that were genotyped on a custom chip (iCOGS). We identified one putatively pathogenic missense mutation c.541C>T among the Finnish cancer patients and subsequently genotyped the mutation in additional breast cancer cases (n = 5259) and population controls (n = 3586) from Finland and Belarus. No significant association with breast cancer risk was seen in the meta-analysis of the Finnish datasets or in the large BCAC dataset. The association with previously identified risk variants rs999737, rs2588809, and rs1314913 was replicated among all breast cancer cases and also among familial cases in the BCAC dataset. The most significant association was observed for the haplotype carrying the risk-alleles of all the three SNPs both among all cases (odds ratio (OR): 1.15, 95% confidence interval (CI): 1.11–1.19, P = 8.88 x 10−16) and among familial cases (OR: 1.24, 95% CI: 1.16–1.32, P = 6.19 x 10−11), compared to the haplotype with the respective protective alleles. Our results suggest that loss-of-function mutations in RAD51B are rare, but common variation at the RAD51B region is significantly associated with familial breast cancer risk. PMID:27149063

  11. Characteristics of breast cancer determined by ultrasound-guided mammotome biopsy

    International Nuclear Information System (INIS)

    Vacuum-assisted core needle biopsy (mammotome biopsy) is useful to avoid diagnostic surgery. The purpose of this study was to evaluate the characteristics of breast cancer determined by ultrasound-guided mammotone biopsy. Fifty-nine breast cancers were included in this study. The histological findings of mammotome biopsy were identical to those of operative specimens in the 55 cancers, including 28 invasive and 27 noninvasive cancers. The median diameters of invasive and noninvasive cancers were 13 and 6.5 mm, respectively. The findings of breast ultrasound for the 27 noninvasive cancers revealed a mass lesion in 16 cancers and non-mass lesion in 11 cancers. The nuclear grade of non-mass lesions was significantly higher than that of mass lesions in the 27 noninvasive cancers (P=0.0093). Breast MRI showed noninvasive cancer in 8 of 11 non-mass lesions. These results suggest that ultrasound-guided mammotome biopsy with breast MRI may be useful to diagnose noninvasive breast cancer. (author)

  12. GLUT 5 is not over-expressed in breast cancer cells and patient breast cancer tissues.

    Directory of Open Access Journals (Sweden)

    Gayatri Gowrishankar

    Full Text Available F18 2-Fluoro 2-deoxyglucose (FDG has been the gold standard in positron emission tomography (PET oncologic imaging since its introduction into the clinics several years ago. Seeking to complement FDG in the diagnosis of breast cancer using radio labeled fructose based analogs, we investigated the expression of the chief fructose transporter-GLUT 5 in breast cancer cells and human tissues. Our results indicate that GLUT 5 is not over-expressed in breast cancer tissues as assessed by an extensive immunohistochemistry study. RT-PCR studies showed that the GLUT 5 mRNA was present at minimal amounts in breast cancer cell lines. Further knocking down the expression of GLUT 5 in breast cancer cells using RNA interference did not affect the fructose uptake in these cell lines. Taken together these results are consistent with GLUT 5 not being essential for fructose uptake in breast cancer cells and tissues.

  13. Dichotomous roles for the orphan nuclear receptor NURR1 in breast cancer

    International Nuclear Information System (INIS)

    NR4A orphan nuclear receptors are involved in multiple biological processes which are important in tumorigenesis such as cell proliferation, apoptosis, differentiation, and glucose utilization. The significance of NR4A family member NURR1 (NR4A2) in breast cancer etiology has not been elucidated. The purpose of this study was to ascertain the impact of NURR1 expression on breast transformation, tumor growth, and breast cancer patient survival. We determined the expression of NURR1 in normal breast versus breast carcinoma in tissue microarrays (immunohistochemistry), tissue lysates (immunoblot), and at the mRNA level (publically available breast microarrays). In addition NURR1 expression was compared among breast cancer patients in cohorts based on p53 expression, estrogen receptor α expression, tumor grade, and lymph node metastases. Kaplan-Meier survival plots were used to determine the correlation between NURR1 expression and relapse free survival (RFS). Using shRNA-mediated silencing, we determined the effect of NURR1 expression on tumor growth in mouse xenografts. Results from breast cancer tissue arrays demonstrate a higher NURR1 expression in the normal breast epithelium compared to breast carcinoma cells (p ≤ 0.05). Among cases of breast cancer, NURR1 expression in the primary tumors was inversely correlated with lymph node metastases (p ≤ 0.05) and p53 expression (p ≤ 0.05). Clinical stage and histological grade were not associated with variation in NURR1 expression. In gene microarrays, 4 of 5 datasets showed stronger mean expression of NURR1 in normal breast as compared to transformed breast. Additionally, NURR1 expression was strongly correlated with increase relapse free survival (HR = 0.7) in a cohort of all breast cancer patients, but showed no significant difference in survival when compared among patients whom have not been treated systemically (HR = 0.91). Paradoxically, NURR1 silenced breast xenografts showed significantly decreased growth

    Breast cancer is the most common female cancer and globally remains a major public health concern. The diagnosis and treatment of breast cancer continues to develop. Diagnosis is now more precise, surgery is less mutilating and women now have the option of breast conserving therapy with better cosmesis, and without sacrificing survival. Radiotherapy is more targeted and the selection of patients for adjuvant chemotherapy is based not only on prognostic and predictive factors, but also on newer molecular profiling that will ensure that chemotherapy is given to the patients who need and respond to it. These developments all provide a more tailored approach to the treatment of breast cancer. Management now involves a multidisciplinary team approach in order to provide the highest standard of care for patients throughout their cancer journey from diagnosis through treatment and into follow-up care.

    Full Text Available BACKGROUND: Depression is prevalent among women and associated with reduced quality of life, and therefore it is important to determine its incidence in adult women, especially in those with breast cancer. OBJECTIVE: To determine the occurrence of depression in women who underwent conservative surgery for breast cancer with or without breast reconstruction. METHODS: Seventy-five women aged between 18 and 65 years were enrolled. Patients had undergone conservative surgery for breast cancer with immediate breast reconstruction (n = 25 or without breast reconstruction (n = 25 at least one year before the study. The control group consisted of 25 women without cancer, but of similar age and educational level distribution as the other two groups. The Beck Depression Inventory was used to measure depression. The collected data were assessed using analysis of variance and the χ2 test. RESULTS: There were no significant differences between groups in age (p = 0.72 or educational level (p = 0.20. A smaller number of patients had undergone the menopause (p = 0.02 in the control group than in other groups. There were no significant differences in occurrence of depression between groups (χ2=9.97; p = 0.126. CONCLUSÍON: Conservative surgery for breast cancer did not affect the occurrence of depression in women, regardless of whether breast reconstruction was performed.

  18. 99m-Tc tetrofosmin scintigraphy vs mammography in breast cancer detection

    International Nuclear Information System (INIS)

    99m-Tc tetrofosmin is a widely used radiotracer for breast cancer imaging. Routine mammography ,as a method for screening breast cancer patients, might be insufficient for diagnosis, especially in patients with dense breast. Aim: The aim of this study was to compare the results of mammography (MM) and scintimammography with 99m- Tc tetrofosmin (SMM) in detection of primary breast cancer. Method: Thirty patients with breast disease were included in study. All of them had clinical investigation, MM, SMM and surgical biopsy for final histological diagnosis. An amount of 600 MBq 99m- Tc tetrofosmin was injected intravenously in the arm opposite to the side of breast lesion. Ten minutes after injection planar breast 7-minutes scans were performed in supine (anterior) and prone (left and right lateral) position. Results: Out of 30 lesion breast cancer was histologically confirmed in 20 (15 ductal invasive, two lobular, one colloid, one papillar carcinoma and one case of cyst sarcoma phylodes- malignant type.) For MM sensitivity of 80%, specificity of 60% and accuracy of 76 % were obtained. At SMM 19/ 20 malignant lesions were detected. Only one false negative result was obtained in 1.0 cm lobular infiltrative cancer, although the smallest detectable lesion measured 0.6 cm. At pathohistology ten lesions presented benign. Four false positive results (two fibroadenomas, one lipogranuloma and one case of fibrocystic disease) were observed, six true negative results in four cases with fibrocystic disease and two fibroadenomas. The overall sensitivity of scintimammography was 95%, specificity 60% and accuracy 83%. Conclusion: We concluded that sensitivity of 99m-Tc tetrofosmin scintimammography in detection of breast cancer is superior to that of mammography. Our results suggest that 99m -Tc tetrofosmin is a suitable tumor seeking agent for breast cancer imaging

    The potential for a reduction in dietary fat or for an increase in dietary fiber to reduce breast cancer risk has been debated for some years. It is argued here that available research data, even though extensive, leave open hypotheses ranging from little or no potential to major public health potential for breast cancer prevention by means of these dietary maneuvers. Some elements of a research strategy for testing these and other dietary breast cancer prevention hypotheses are described.

    Only a few years ago, the poultry industry began to face a recent abnormality in breast meat, known as wooden breast, which frequently overlaps with white striping. This study aimed to assess the impact of wooden breast abnormality on quality traits of meat. For this purpose, 32 normal (NRM), 32 wooden (WB), and 32 wooden and white-striped (WB/WS) Pectoralis major muscles were selected from the same flock of heavy broilers (males, Ross 708, weighing around 3.7 kg) in the deboning area of a commercial processing plant at 3 h postmortem and used to assess histology, proximate (moisture, protein, fat, ash, and collagen) and mineral composition (Mg, K, P, Na and Ca), sarcoplasmic and myofibrillar protein patterns, and technological traits of breast meat. Compared to the normal group, WB/WS fillets showed more severe histological lesions characterized by fiber degeneration, fibrosis, and lipidosis, coupled with a significantly harder texture. With regard to proximate and mineral composition, abnormal samples exhibited significantly (P < 0.001) higher moisture, fat, and collagen contents coupled with lower (P < 0.001) amounts of protein and ash. Furthermore, increased calcium (131 vs. 84 mg kg(-1); P < 0.05) and sodium (741 vs. 393 mg kg(-1); P < 0.001) levels were found in WB/WS meat samples. The SDS-PAGE analysis revealed a significantly lower amount of calcium-ATPase (SERCA, 114 kDa), responsible for the translocation of Ca ions across the membrane, in normal breasts compared to abnormal ones. As for meat quality traits, fillets affected by wooden abnormality exhibited significantly (P < 0.001) higher ultimate pH and lower water-holding/water-binding capacity. In particular, compared to normal, abnormal samples showed reduced marinade uptake coupled with increased drip loss and cooking losses as well. In conclusion, this study revealed that meat affected by wooden breast or both wooden breast and white striping abnormalities exhibit poorer nutritional value, harder

  4. Heavy-ion mammography and breast cancer

    International Nuclear Information System (INIS)

    Heavy-ion radiography is a new diagnostic imaging technique developed in our laboratory that produces superior density resolution at low radiation doses. Heavy-ion mammography has now emerged as a low-dose, safe, reliable, noninvasive diagnostic radiological procedure that can quantitate and image very small differences in soft tissue densities in the breast tissues of patients with clinical breast disease. The improved density resolution of heavy-ion mammography over conventional X-ray mammography and breast xerography provides the potential of detecting small breast cancers of less than 1 cm diameter. The radiation dose to the breast from carbon-ion mammorgraphy is about 50 mrad or less, and can potentially be only a fraction of this level. The results of the present clinical trial in progress of heavy-ion mammography in 37 patients, thus far studied, are extremely encouraging, and warrant continued study for application to the early diagnosis of breast cancer in women

    of epirubicin and the presence of TOP2A, but not the presence of HER2 aberrations. The results obtained in the 89D trial regarding TOP2A have been reproduced by others, but not consistently. However, a recent individual-patient pooled analysis of five adjuvant trials demonstrated that patients with either TOP2A or centromere 17 aberrations, but not with HER2 amplification, benefit from anthracycline-containing adjuvant chemotherapy. Anthracyclins have additional distinct biological mechanisms; and results from the DBCG 89D suggested that tumours with normal TOP2A were only non-responsive to anthracyclines if they were TIMP1 immunoreactive. The DBCG READ trial (N = 2,015) prospectively included patients without TOP2A-aberrated breast cancers, and its results are awaited for prospective confirmation of the results from the DBCG 89D and the individual-patient pooled analysis. Adjuvant chemotherapy substantially reduces the risk of recurrence and mortality of breast cancer, but is also associated with significant toxicity. However, according to a large cohort study from DBCG, chemotherapy can safely be withheld in one fourth of postmenopausal patients who will be without excess mortality following sufficient adjuvant endocrine therapy for ER positive breast cancer. A prognostic standard mortality rate index (PSI) was constructed using regression coefficients obtained in a multivariate fractional polynomials model, and most accurately identified those who could be spared chemotherapy. In addition to age, tumour size, nodal status, histological type and malignancy grade, the PSI also includes ER level addressed as a continuous variable in the MFP model. In the MFP model, absence of LVI was sufficient to counteract the impact of other risk factors, while that could not be achieved with a categorical multivariate model in a prior study. An evaluation of whether the addition of results from a molecular assay may improve the clinical utility of the PSI is on-going, but when

    Full Text Available Michael Untch1, Christian Jackisch21Interdisciplinary Breast Centre, Helios Klinikum Berlin-Buch, University Charité, Berlin, Germany; 2Department of Gynecology/Obstetrics, Klinikum Offenbach GmbH, Offenbach, GermanyAbstract: The adjuvant treatment of women with endocrine-sensitive early breast cancer has been dominated for the last 40 years by tamoxifen. However, the side-effects associated with this therapy have prompted a search for safer and biochemically more selective endocrine agents and led to the development of the third-generation aromatase inhibitors (AIs anastrozole, letrozole and exemestane. Promising results in advanced disease have paved the way for treating early breast cancer, and AIs are increasingly replacing tamoxifen in the adjuvant setting. Several large, randomized trials with AIs have been completed or are ongoing in women with early-stage breast cancer, documenting the significant impact that these drugs are making on the risk for recurrence of breast cancer. As a result, there is increasing and widespread use of AI therapy for the treatment of early-stage endocrine-responsive breast cancer. This review summarizes the data for exemestane in the adjuvant setting, showing that a switch to exemestane after 2 to 3 years of tamoxifen therapy is associated with a statistically significant survival benefit and is regarded as being sensitive by international and national experts.Keywords: early breast cancer, adjuvant setting, endocrine-sensitive, tamoxifen, aromatase inhibitor, exemestane, switch, IES 31, NSABP B-33, TEAM

  10. TOX3 mutations in breast cancer.

    Directory of Open Access Journals (Sweden)

    James Owain Jones

    Full Text Available TOX3 maps to 16q12, a region commonly lost in breast cancers and recently implicated in the risk of developing breast cancer. However, not much is known of the role of TOX3 itself in breast cancer biology. This is the first study to determine the importance of TOX3 mutations in breast cancers. We screened TOX3 for mutations in 133 breast tumours and identified four mutations (three missense, one in-frame deletion of 30 base pairs in six primary tumours, corresponding to an overall mutation frequency of 4.5%. One potentially deleterious missense mutation in exon 3 (Leu129Phe was identified in one tumour (genomic DNA and cDNA. Whilst copy number changes of 16q12 are common in breast cancer, our data show that mutations of TOX3 are present at low frequency in tumours. Our results support that TOX3 should be further investigated to elucidate its role in breast cancer biology.

  11. Risk-benefit analysis of preoperative breast MRI in patients with primary breast cancer

    International Nuclear Information System (INIS)

    Aim: To analyse and compare the risks and benefits of preoperative breast MRI (BMRI) in patients with primary breast cancer (PBC), and to determine the influence of mammographic breast density (BD) and histological tumour type (TT). Materials and Methods: One hundred and nineteen patients who underwent preoperative bilateral breast MRI for staging of PBC during a 1-year period from July 2005 to August 2006 were prospectively evaluated. Changes in clinical management due to BMRI findings were recorded. MRI-detected lesions were correlated with histology. Additional MRI-detected malignant lesions and spared additional biopsies because of negative MRI in case of unclear ultrasound findings were determined as beneficial for the patient. Biopsies of benign MRI detected lesions were defined as disadvantageous. The influence of BD (ACR 1-4) and TT on the change in clinical management and patient benefit was evaluated. Results: The findings of the BMRI examinations changed the clinical management in 48 patients (40.3%). Seventeen women underwent mastectomy instead of breast conservation, eight patients underwent extended excision, 21 additional lesions were clarified by MRI intervention, and two ultrasound-detected lesions were not biopsied because of negative MRI. Histologically malignant additional or extended biopsies (n = 34) and two cases of spared biopsies resulted in 36 (30.3%) women who benefited from preoperative BMRI. Twelve patients (10.1%) had additional biopsies of MRI-detected benign lesions, and therefore, had an unfavourable outcome due to BMRI. The change in clinical management and patient benefit were independent of BD and TT (p > 0.05). Conclusion: Preoperative BMRI was beneficial for 30.3% of 119 patients with PBC. The percentage of additional biopsies of benign lesions (10.1%) seems acceptable

    Full Text Available A spiculated mass on a mammogram is highly suggestive of malignancy. We report the case of a 32-year-old woman with a radial sclerosing lesion that mimicked breast cancer on mammography. She visited her physician after palpating a lump in her left breast. Mammography showed architectural distortion in the upper inner quadrant of the left breast. Ultrasonography showed a low echoic area with an ambiguous boundary. Core needle biopsy was performed because of the suspicion of malignancy. Histological examination did not reveal any malignant cells. After 6 months, the breast lump became larger and the patient was referred to our hospital. Mammography performed in our hospital showed a spiculated mass, and therefore mammotome biopsy was performed. Histological examination revealed dense fibroelastic stroma with a wide variety of mastopathic changes, leading to a diagnosis of a radial sclerosing lesion. One year after the biopsy, the lump on her left breast had disappeared and mammography showed no spiculated mass.

    Breast cancer is the most frequently diagnosed cancer in women. Early detection of breast cancer is known to increase survival rates significantly after diagnosis. This research was carried out to determine the level of breast cancer risk among primary healthcare nurses and their belief in breast cancer screening. In this descriptive research, the data were collected in face-to-face interviews with the participants. The researchers contacted all primary healthcare nurses currently working in the province. The data collection tools included a questionnaire form on sociodemographic characteristics, breast cancer risk assessment form, and Champion's Health Belief Model Scale (CHBMS) for breast cancer screening. In data analysis, descriptive statistics, t test, and analysis of variance (ANOVA) were used. The mean age of nurses was 35 ± 3.6. The mean score for the breast cancer risk assessment form was calculated as 82.9 ± 18.7. The subscale scores for the CHBMS for breast cancer screening were as follows: susceptibility 7.3 ± 1.8, seriousness 19.5 ± 4.1, benefits of breast self-exam 15.5 ± 2.6, barriers to breast self-exam 15.1 ± 2.8, self-efficacy 40.3 ± 7.0, and motivation 19.5 ± 4.1. The risk of breast cancer was found to be low in the study group. The analysis of the subscale scores for the CHBMS for breast cancer screening revealed that nurses had a below-average susceptibility perception, a somewhat lower perception of seriousness, an above-average mean score for perceived benefits, a moderate barrier perception, a relatively high perceived self-efficacy, and motivation above average.

    Full Text Available Abstract Background Clustering analysis of microarray data is often criticized for giving ambiguous results because of sensitivity to data perturbation or clustering techniques used. In this paper, we describe a new method based on principal component analysis and ensemble consensus clustering that avoids these problems. Results We illustrate the method on a public microarray dataset from 36 breast cancer patients of whom 31 were diagnosed with at least two of three pathological stages of disease (atypical ductal hyperplasia (ADH, ductal carcinoma in situ (DCIS and invasive ductal carcinoma (IDC. Our method identifies an optimum set of genes and divides the samples into stable clusters which correlate with clinical classification into Luminal, Basal-like and Her2+ subtypes. Our analysis reveals a hierarchical portrait of breast cancer progression and identifies genes and pathways for each stage, grade and subtype. An intriguing observation is that the disease phenotype is distinguishable in ADH and progresses along distinct pathways for each subtype. The genetic signature for disease heterogeneity across subtypes is greater than the heterogeneity of progression from DCIS to IDC within a subtype, suggesting that the disease subtypes have distinct progression pathways. Our method identifies six disease subtype and one normal clusters. The first split separates the normal samples from the cancer samples. Next, the cancer cluster splits into low grade (pathological grades 1 and 2 and high grade (pathological grades 2 and 3 while the normal cluster is unchanged. Further, the low grade cluster splits into two subclusters and the high grade cluster into four. The final six disease clusters are mapped into one Luminal A, three Luminal B, one Basal-like and one Her2+. Conclusion We confirm that the cancer phenotype can be identified in early stage because the genes altered in this stage progressively alter further as the disease progresses through DCIS

  17. Effects of irradiation for cervical cancer on subsequent breast cancer

    International Nuclear Information System (INIS)

    Previous research suggests that cervical cancer patients have a lower risk of breast cancer than women in the general population. Possible explanations include opposing risk factors for cervical cancer and breast cancer, the effect of irradiation used to treat cervical cancer, or both. The purpose of this study was to explore the relationship between irradiation for cervical cancer and the subsequent development of breast cancer. There was no statistically significant relationship between radiation to the ovarian area and the risk of breast cancer in this study. However, the results were consistent with a 19% reduction in risk for women irradiated for cervical cancer when compared to nonirradiated women. In a dose-response analysis, there was a nonsignificant trend of decreased risk of breast cancer with increased radiation up to 1800 rad. There was no consistent pattern for higher doses. The trend, although nonsignificant, differed by age. Women <60 years of age at irradiation were generally at a lower risk of breast cancer than nonirradiated women. Women over 59 years were at an increased risk. There are some potentially important findings from this study which might influence medical care. These should be examined in the larger International Radiation Study

    Breast cancer is a complex disease encompassing multiple tumor entities, each characterized by distinct morphology, behavior and clinical implications. Besides estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2, novel biomarkers have shown their prognostic and predictive values, complicating our understanding towards to the heterogeneity of such cancers. Ten cancer hallmarks have been proposed by Weinberg to characterize cancer and its carcinogenesis. By reviewing biomarkers and breast cancer molecular subtypes, we propose that the divergent outcome observed from patients stratified by hormone status are driven by different cancer hallmarks. 'Sustaining proliferative signaling' further differentiates cancers with positive hormone receptors. 'Activating invasion and metastasis' and 'evading immune destruction' drive the differentiation of triple negative breast cancers. 'Resisting cell death', 'genome instability and mutation' and 'deregulating cellular energetics' refine breast cancer classification with their predictive values. 'Evading growth suppressors', 'enabling replicative immortality', 'inducing angiogenesis' and 'tumor-promoting inflammation' have not been involved in breast cancer classification which need more focus in the future biomarker-related research. This review novels in its global view on breast cancer heterogeneity, which clarifies many confusions in this field and contributes to precision medicine. PMID:27390604

    Full Text Available Heather L McArthur, Patrick G MorrisBreast Cancer Medicine Service, Department of Medicine, Memorial Sloan-Kettering Cancer Center, New York, NY, USAAbstract: Despite ongoing therapeutic innovations, metastatic breast cancer (MBC remains a treatable but incurable disease. In the developed world, a diagnosis of MBC without a preceding diagnosis of early stage disease is a rare event. However, approximately one-third of women with early stage breast cancer ultimately experience a distant recurrence. Because the majority of breast cancers express estrogen and/or progesterone receptors and are accordingly considered hormone-sensitive, therapeutic strategies that interfere with hormone-mediated tumorigenesis have been a cornerstone of the breast cancer management paradigm for decades. Historically, the selective estrogen receptor modulator tamoxifen has been the most extensively studied and widely used hormone maneuver in breast cancer. However, a recent therapeutic innovation, namely the successful development of third-generation aromatase inhibitors (AIs, has had a dramatic impact on the treatment paradigm for women with hormone-sensitive MBC. Because of the demonstrated efficacy in postmenopausal breast cancer patients, the generally favorable side-effect profile, and the convenience of oral administration, AIs are now in widespread clinical use. Currently, there are three clinically available third-generation AIs: two reversible, nonsteroidal AIs, letrozole and anastrozole; and one irreversible, steroidal AI, exemestane. All three agents are at least as efficacious as tamoxifen as monotherapy for postmenopausal women with hormone-sensitive MBC. Current clinical research aims to improve upon existing strategies by evaluating AIs in combination with systemic chemotherapy regimens and/or novel targeted agents.

    Full Text Available Christina M Dieli-Conwright, Breanna Z Orozco Division of Biokinesiology and Physical Therapy, Women's Health and Exercise Laboratory, University of Southern California, Los Angeles, CA, USA Abstract: Over the past 2 decades, great strides have been made in the field of exercise-oncology research, particularly with breast cancer. This area of research is particularly important since there are >2.8 million breast cancer survivors who are in need of an intervention that can offset treatment-related side effects. Noticeable reductions in physical fitness (ie, cardiopulmonary fitness and muscular strength, negative changes in body composition (ie, increase in body mass, decrease in lean body mass, and increase in fat mass, increased fatigue, depression, or anxiety are some of the common side effects of cancer treatments that negatively impact overall quality of life and increase the risk for the development of comorbidities. Exercise plays a vital role in improving cardiopulmonary function, psychological events, muscular strength, and endurance in breast cancer survivors, and thus should be considered as a key factor of lifestyle intervention to reverse negative treatment-related side effects. The purpose of this review is to address current perspectives on the benefits of aerobic and resistance exercise after breast cancer treatments. This review is focused on the well-established benefits of exercise on physical and emotional well-being, bone health, lymphedema management, and the postulated benefits of exercise on risk reduction for recurrence of breast cancer.

    Central nervous system or brain metastases traditionally occur in 10-16% of metastatic breast cancer patients and are associated with a dismal prognosis. The development of brain metastases has been associated with young age, and tumors that are estrogen receptor negative, Her-2+ or of the basal phenotype. Treatment typically includes whole brain irradiation, or either stereotactic radiosurgery or surgery with whole brain radiation, resulting in an approximately 20% one year survival. The blood-brain barrier is a formidable obstacle to the delivery of chemotherapeutics to the brain. Mouse experimental metastasis model systems have been developed for brain metastasis using selected sublines of human MDA-MB-231 breast carcinoma cells. Using micron sized iron particles and MRI imaging, the fate of MDA-MB-231BR cells has been mapped: Approximately 2% of injected cells form larger macroscopic metastases, while 5% of cells remain as dormant cells in the brain. New therapies with permeability for the blood-brain barrier are needed to counteract both types of tumor cells. PMID:17473372

  12. Low expression of TFPI-2 associated with poor survival outcome in patients with breast cancer

    International Nuclear Information System (INIS)

    The purpose of this study is to evaluate the prognostic value of TFPI-2 expression in breast cancer patients through examining the correlation between TFPI-2 expression and breast cancer clinicopathologic features. Immunohistochemical staining combined with digital image analysis was used to quantify the expression of TFPI-2 protein in breast tumor tissues. For evaluation of the prognostic value of TFPI-2 expression to each clinicopathologic factor, Kaplan-Meier method and COX’s Proportional Hazard Model were employed. TFPI-2 expression was significantly correlated with tumor size, lymph node metastasis, histologic grade, clinical stage, and vessel invasion. More importantly, TFPI-2 expression was also associated with disease-free survival (DFS) of breast cancer patients. We found that patients with high TFPI-2 expression had longer DFS compared with those with low or negative expression of TFPI-2 (P <0.05, log-rank test). Cox’s regression analysis indicated that TFPI-2 expression, histologic grade, and vessel invasion might be significant prognostic factors for DFS, while TFPI-2 expression and histologic grade were the most significant independent predictors for tumor recurrence. Compared with the group with low/high TFPI-2 expression, the TFPI-2 negative group was more likely to have tumor relapse. The hazard ratio of DFS is 0.316 (P <0.01). Low or negative expression of TFPI-2 is associated with breast cancer progression, recurrence and poor survival outcome after breast cancer surgery. TFPI-2 expression in breast tumors is a potential prognostic tool for breast cancer patients

  13. Radiation-induced breast cancer

    International Nuclear Information System (INIS)

    Concern is expressed over a recent U.K. newspaper report (The Times, 21 January 1977, 5) on the possible hazards of mammography, as women may over-react to the extent of refusing mammography. The problems of radiation risk estimates, particularly at low dose levels, are very briefly reviewed. Recent improvements in mammography techniques have minimised the radiation hazard. Conflicting reports of the mortality rates following mammography screening programmes are discussed. In England and Wales, breast cancer is the commonest cause of death in women aged 35 to 54, and it would be unfortunate if the possible benefits of screening were denied to this age group before the latest mammographic techniques have been fully evaluated.

    Currently, many breast cancer patients with localized breast cancer undergo breast-conserving therapy, consisting of local excision followed by radiation therapy. Following radiation therapy, breast cancer cells are noted to undergo induction of autophagy, development of radioresistance, and enrichment of breast cancer stem cell subpopulations. It is hypothesized that inhibition of the cytoprotective autophagy that arises following radiation therapy increases radiosensitivity and confers long...

  18. Increased risk of breast cancer in splenectomized patients undergoing radiation therapy for Hodgkin's disease

    International Nuclear Information System (INIS)

    Purpose: Second malignancies have been reported among patients who were treated by radiation therapy or chemotherapy alone or in combination. Studies have implied an increased risk of breast cancer in women who received radiotherapy as part of their treatment for Hodgkin's disease. This review was performed to determine if there is an association between splenectomy and subsequent breast cancer. Methods and Materials: One hundred and thirty-six female patients with histologically proven Hodgkin's disease were seen in the Division of Radiation Oncology between 1962 and 1985. All patients received mantle or mediastinal irradiation as part of their therapy. The risk of breast cancer was assessed and multiple linear regression analysis was performed on the following variables: patient age, stage, dose and extent of radiation field, time after completing radiation therapy, splenectomy, and chemotheraphy. Results: Breast cancer was observed in 11 of 74 splenectomized patients and in none of 62 patients not splenectomized. The mean follow-up was 13 years in splenectomized patients and 16 years, 7 months in nonsplenectomized patients. Nine patients developed invasive breast cancer and two developed ductal carcinoma in situ. Splenectomy was the only variable independently associated with an increased risk of breast cancer (p < 0.005) in multiple linear regression analysis; age, latency, and splenectomy considered together were also associated with an increased risk of breast cancer (p < 0.01). Conclusion: Our data show an increased risk of breast cancer in splenectomized patients who had treatment for Hodgkin's disease. A multiinstitutional survey may better define the influence of splenectomy relative to developing breast cancer in patients treated for Hodgkin's disease. The risk of breast cancer should be considered when recommending staging laparotomy, and we recommend close follow-up examination including routine mammograms for female patients successfully treated for
