    Full Text Available Breast cancer is the most common malignancy in women and early detection is important for its successful treatment. The aim of this study was to investigate the sensitivity and specificity of three methods for early detection of breast cancer: breast magnetic resonance imaging (MRI, digital mammography, and breast tomosynthesis in comparison to histopathology, as well as to investigate the intraindividual variability between these modalities.  We included 57 breast lesions, each detected by three diagnostic modalities: digital mammography, breast MRI, and breast tomosynthesis, and subsequently confirmed by histopathology. Breast Imaging-Reporting and Data System (BI-RADS was used for characterizing the lesions. One experienced radiologist interpreted all three diagnostic modalities. Twenty-nine of the breast lesions were malignant while 28 were benign. The sensitivity for digital mammography, breast MRI, and breast tomosynthesis, was 72.4%, 93.1%, and 100%, respectively; while the specificity was 46.4%, 60.7%, and 75%, respectively. Receiver operating characteristics (ROC curve analysis showed an overall diagnostic advantage of breast tomosynthesis over both breast MRI and digital mammography. The difference in performance between breast tomosynthesis and digital mammography was significant (p < 0.001, while the difference between breast tomosynthesis and breast MRI was not significant (p = 0.20.

    Breast cancer is one of the leading causes of deaths worldwide among women. Early tumor detection is key in reducing breast cancer deaths and screening mammography is the widest available method for early detection. Mammography is the most common and effective breast cancer screening test. However, the rate of positive findings is very low, making the radiologic interpretation monotonous and biased toward errors. In an attempt to alleviate radiological workload, this work presents a computer-aided diagnosis (CAD x) method aimed to automatically classify tumor lesions into malign or benign as a means to a second opinion. The CAD x methos, extracts image features, and classifies the screening mammogram abnormality into one of two categories: subject at risk of having malignant tumor (malign), and healthy subject (benign). In this study, 143 abnormal segmentation s (57 malign and 86 benign) from the Breast Cancer Digital Repository (BCD R) public database were used to train and evaluate the CAD x system. Percentile-rank (p-rank) was used to standardize the data. Using the LASSO feature selection methodology, the model achieved a Leave-one-out-cross-validation area under the receiver operating characteristic curve (Auc) of 0.950. The proposed method has the potential to rank abnormal lesions with high probability of malignant findings aiding in the detection of potential malign cases as a second opinion to the radiologist.

    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.

    Tumour size estimates using mammography (MG), conventional ultrasound (US), compound imaging (CI) and real-time elastography (RTE) were compared with histopathological specimen sizes. The largest diameters of 97 malignant breast lesions were measured. Two US and CI measurements were made: US1/CI1 (hypoechoic nucleus only) and US2/CI2 (hypoechoic nucleus plus hyperechoic halo). Measurements were compared with histopathological tumour sizes using linear regression and Bland-Altman plots. Size prediction was best with ultrasound (US/CI/RTE: R{sup 2} 0.31-0.36); mammography was poorer (R{sup 2} = 0.19). The most accurate method was US2, while US1 and CI1 were poorest. Bland-Altman plots showed better size estimation with US2, CI2 and RTE, with low variation, while mammography showed greatest variability. Smaller tumours were better assessed than larger ones. CI2 and US2 performed best for ductal tumours and RTE for lobular cancers. Tumour size prediction accuracy did not correlate significantly with breast density, but on MG tumours were more difficult to detect in high-density tissue. The size of ductal tumours is best predicted with US2 and CI2, while for lobular cancers RTE is best. Hyperechoic tumour surroundings should be included in US and CI measurements and RTE used as an additional technique in the clinical staging process. (orig.)

    Full Text Available Abstract Background Breast cancer remains an important public health problem. This study aimed to investigate about female knowledge of breast cancer and self-reported practice of breast self-examination in Iran. Methods This was a population-based survey carried out in Tehran, Iran. Data were collected via a structured questionnaire containing 15 questions on demographic status, history of personal and family breast problems, subjective knowledge about breast cancer covering its symptoms, the screening methods and practice of breast self-examination (BSE. A trained female nurse interviewed each respondent. Analysis included descriptive statistics and the Chi-squared test where necessary. Results A total of 1402 women were interviewed. The mean age of respondents was 43.4 (SD = 14.4 years; most were married (85%, and without any personal (94% and family history (90% of breast problems. It was found that 64% of the respondents were familiar with breast cancer and 61% (n = 851 believed that 'the disease is relatively common among women in Iran'. Most women (44% perceived a painless mass as a breast cancer symptom. Overall, 61% of the respondents stated that they knew about breast cancer screening programs and most indicated that electronic media (television 34% and radio 14% were their source of information. Only 17% of women said that 'they were conducting regular breast self-examination'. The main reason for women not doing breast self-examination was due to the fact that they did not know how to do it (64%. The findings indicated that performing breast self-examination is significantly related to: age, marital status, education, knowledge of breast cancer and knowledge about breast cancer screening programs (p Conclusion This descriptive study provides useful information that could be utilized by both researchers and those involved in public health programmes. The findings indicated that the women awareness of breast cancer warning signs

    2008-03-01

    Women with high mammographic breast density are at 4- to 6-fold increased risk of developing breast cancer compared to women with fatty breasts. However, current breast density estimations rely on mammography, which cannot provide accurate volumetric breast representation. Therefore, we explored two techniques of breast density evaluation via ultrasound tomography. A sample of 93 patients was imaged with our clinical prototype; each dataset contained 45-75 tomograms ranging from near the chest wall through the nipple. Whole breast acoustic velocity was determined by creating image stacks and evaluating the sound speed frequency distribution. Ultrasound percent density (USPD) was determined by segmenting high sound speed areas from each tomogram using k-means clustering, integrating over the entire breast, and dividing by total breast area. Both techniques were independently evaluated using two mammographic density measures: (1) qualitative, determined by a radiologist's visual assessment using BI-RADS Categories, and (2) quantitative, via semi-automatic segmentation to calculate mammographic percent density (MPD) for craniocaudal and medio-lateral oblique mammograms. ~140 m/s difference in acoustic velocity was observed between fatty and dense BI-RADS Categories. Increased sound speed was found with increased BI-RADS Category and quantitative MPD. Furthermore, strong positive associations between USPD, BI-RADS Category, and calculated MPD were observed. These results confirm that utilizing sound speed, both for whole-breast evaluation and segmenting locally, can be implemented to evaluate breast density.

    Full Text Available Introduction & Objective: The breast cancer is the most common malignancy in women and in recent years it is seen in younger ages. Because of dense breast tissue in these ages, the mammography sensitivity for breast cancer detection is reduced, so high quality ultrasonography (US as a combined screening method is effective. The aim of this study is the evaluation of the mammographic finding with the positive finding of ultrasonogarphy.Materials & Methods: In this cross-sectional study 300 cases were referred to the Mehr Medical Imaging Center for breast US and sonography of breast and axilla was performed. Mammography before or after US was also performed by another radiologist. All suspicious patients were referred for biopsy or surgery.Results: Mean age of patients was 46 y/o with the range of 32-76 y/o. Pathologic specimens approved malignancy in 21 patients and abscess in 1 patient. The most frequent symptom was palpable breast mass with mean diameter of 29 mm. Mean diameter of lymph nodes was 17.3 mm. Positive mammographic findings were seen in 85.7%and negative findings or only an asymmetric density in 14.3%.Conclusion: According to dense breast tissue especially in young women sensitivity of single screening by mammography is reduced in breast cancer detection, so combined screening with sonography and mammography especially in younger women improves the detection rate of breast carcinoma.

    Asian women, including Korean, have a relatively higher incidence of dense breast tissue, compared with western women. Dense breast tissue has a lower sensitivity for the detection of breast cancer and a higher relative risk for breast cancer, compared with fatty breast tissue. Thus, there were limitations in the mammographic screening for women with dense breast tissue, and many studies for the supplemental screening methods. This review included appropriate screening methods for Korean women with dense breasts. We also reviewed the application and limitation of supplemental screening methods, including breast ultrasound, digital breast tomosynthesis, and breast magnetic resonance imaging; and furthermore investigated the guidelines, as well as the study results.

    Full Text Available Breast cancer stem cells were considered as origins of breast cancer. Previously published studies showed that breast cancer stem cells exhibited high multi-drug resistance. This study aimed to evaluate the spontaneous differentiation of human breast cancer stem cells and investigate some in vitro conditions to control this process. Human breast cancer stem cells (BCSCs were sorted from primary culture of breast malignant tumors based on expression of CD44 and CD24. The in vitro spontaneous differentiation of BCSCs was evaluated in the popular culture medium DMEM/F12 supplemented with 10% fetal bovine serum (FBS, 1% antibiotic-antimycotic. There were some different methods to control the spontaneous differentiation of BCSCs included free serum culture, mammosphere culture, basic fibroblast growth factor and epidermal growth factor supplement to serum medium, and hypoxia culture. The results showed that BCSCs always were spontaneously differentiated in vitro in the popular culture medium DMEM/F12 plus 10% FBS. The percentage of BCSCs gradually decreased according to sub-culture times and became stable after 20 sub-culture times. All investigated methods could not completely inhibit the spontaneous differentiation of BCSCs. Serum-free culture combined with hypoxia condition had strongest inhibition of this process. These results demonstrated that the spontaneous differentiation is nature process of BCSCs; therefore this process should be determined and suitably controlled depending on different experiments.

    Full Text Available Abstract Background Breast cancer is one of the leading causes of women's death worldwide. It is important to discover a reliable biomarker for the detection of breast cancer. Plasma is the most ideal source for cancer biomarker discovery since many cells cross-communicate through the secretion of soluble proteins into blood. Methods Plasma proteomes obtained from 6 breast cancer patients and 6 normal healthy women were analyzed by using the isotope-coded affinity tag (ICAT labeling approach and tandem mass spectrometry. All the plasma samples used were depleted of highly abundant 6 plasma proteins by immune-affinity column chromatography before ICAT labeling. Several proteins showing differential abundance level were selected based on literature searches and their specificity to the commercially available antibodies, and then verified by immunoblot assays. Results A total of 155 proteins were identified and quantified by ICAT method. Among them, 33 proteins showed abundance changes by more than 1.5-fold between the plasmas of breast cancer patients and healthy women. We chose 5 proteins for the follow-up confirmation in the individual plasma samples using immunoblot assay. Four proteins, α1-acid glycoprotein 2, monocyte differentiation antigen CD14, biotinidase (BTD, and glutathione peroxidase 3, showed similar abundance ratio to ICAT result. Using a blind set of plasmas obtained from 21 breast cancer patients and 21 normal healthy controls, we confirmed that BTD was significantly down-regulated in breast cancer plasma (Wilcoxon rank-sum test, p = 0.002. BTD levels were lowered in all cancer grades (I-IV except cancer grade zero. The area under the receiver operating characteristic curve of BTD was 0.78. Estrogen receptor status (p = 0.940 and progesterone receptor status (p = 0.440 were not associated with the plasma BTD levels. Conclusions Our study suggests that BTD is a potential serological biomarker for the detection of breast cancer.

    In spite of the usefulness of the Ki-67 labeling index (LI) as a prognostic and predictive marker in breast cancer, its clinical application remains limited due to variability in its measurement and the absence of a standard method of interpretation. This study was designed to compare the two methods of assessing Ki-67 LI: the average method vs. the hot spot method and thus to determine which method is more appropriate in predicting prognosis of luminal/HER2-negative breast cancers. Ki-67 LIs were calculated by direct counting of three representative areas of 493 luminal/HER2-negative breast cancers using the two methods. We calculated the differences in the Ki-67 LIs (ΔKi-67) between the two methods and the ratio of the Ki-67 LIs (H/A ratio) of the two methods. In addition, we compared the performance of the Ki-67 LIs obtained by the two methods as prognostic markers. ΔKi-67 ranged from 0.01% to 33.3% and the H/A ratio ranged from 1.0 to 2.6. Based on the receiver operating characteristic curve method, the predictive powers of the KI-67 LI measured by the two methods were similar (Area under curve: hot spot method, 0.711; average method, 0.700). In multivariate analysis, high Ki-67 LI based on either method was an independent poor prognostic factor, along with high T stage and node metastasis. However, in repeated counts, the hot spot method did not consistently classify tumors into high vs. low Ki-67 LI groups. In conclusion, both the average and hot spot method of evaluating Ki-67 LI have good predictive performances for tumor recurrence in luminal/HER2-negative breast cancers. However, we recommend using the average method for the present because of its greater reproducibility. PMID:28187177

    In this work, breast cancer treatment methods are determined using data mining. For this purpose, software is developed to help to oncology doctor for the suggestion of application of the treatment methods about breast cancer patients. 462 breast cancer patient data, obtained from Ankara Oncology Hospital, are used to determine treatment methods for new patients. This dataset is processed with Weka data mining tool. Classification algorithms are applied one by one for this dataset and results are compared to find proper treatment method. Developed software program called as "Treatment Assistant" uses different algorithms (IB1, Multilayer Perception and Decision Table) to find out which one is giving better result for each attribute to predict and by using Java Net beans interface. Treatment methods are determined for the post surgical operation of breast cancer patients using this developed software tool. At modeling step of data mining process, different Weka algorithms are used for output attributes. For hormonotherapy output IB1, for tamoxifen and radiotherapy outputs Multilayer Perceptron and for the chemotherapy output decision table algorithm shows best accuracy performance compare to each other. In conclusion, this work shows that data mining approach can be a useful tool for medical applications particularly at the treatment decision step. Data mining helps to the doctor to decide in a short time.

    2006-04-01

    The treatment of breast cancer has made significant improvements during the past ten years. For early breast cancer with a clinically negative axilla sentinel node biopsy has become the preferred approach. For endocrine therapy of postmenopausal patients the selective aromatase inhibitors have become standard in metastatic as well as in early breast cancer. Trastuzumab (Herceptin) plays an important role in the treatment of HER2-positive breast cancer in the metastatic and since 2005 also in the adjuvant setting. When chemotherapy is used to treat metastatic breast cancer drug combinations are superior to monotherapy only in terms of response rates. By contrast, in the adjuvant setting combination drug therapy is the standard. New methods of tissue analysis including expression patterns of mRNA and proteins are promising research strategies to further advance the field.

    OBJECTIVES: When estimating the decline in breast cancer mortality attributable to screening, the challenge is to provide valid comparison groups and to distinguish the screening effect from other effects. In Funen, Denmark, multidisciplinary breast cancer management teams started before screening...... was introduced; both activities came later in the rest of Denmark. Because Denmark had national protocols for breast cancer treatment, but hardly any opportunistic screening, Funen formed a "natural experiment", providing valid comparison groups and enabling the separation of the effect of screening from other...... factors. METHODS: Using Poisson regression we compared the observed breast cancer mortality rate in Funen after implementation of screening with the expected rate without screening. The latter was estimated from breast cancer mortality in the rest of Denmark controlled for historical differences between...

  16. Optimized Method for Untargeted Metabolomics Analysis of MDA-MB-231 Breast Cancer Cells

    Directory of Open Access Journals (Sweden)

    Amanda L. Peterson

    2016-09-01

    Full Text Available Cancer cells often have dysregulated metabolism, which is largely characterized by the Warburg effect—an increase in glycolytic activity at the expense of oxidative phosphorylation—and increased glutamine utilization. Modern metabolomics tools offer an efficient means to investigate metabolism in cancer cells. Currently, a number of protocols have been described for harvesting adherent cells for metabolomics analysis, but the techniques vary greatly and they lack specificity to particular cancer cell lines with diverse metabolic and structural features. Here we present an optimized method for untargeted metabolomics characterization of MDA-MB-231 triple negative breast cancer cells, which are commonly used to study metastatic breast cancer. We found that an approach that extracted all metabolites in a single step within the culture dish optimally detected both polar and non-polar metabolite classes with higher relative abundance than methods that involved removal of cells from the dish. We show that this method is highly suited to diverse applications, including the characterization of central metabolic flux by stable isotope labelling and differential analysis of cells subjected to specific pharmacological interventions.

    The possibility of breast cancer diagnostics by means of phase structure measurements of laser radiation transformed by human blood plasma samples. The theoretical fundamentals of polarization filtration method for direct phase shifts measurements of microscopic images are provided. The optical model of polycrystalline networks of blood plasma proteins is suggested. The results of investigating the interrelation between the values of statistical (statistical moments of the 1st-4th order), correlation (correlation area, asymmetry coefficient and autocorrelation function excess) and fractal (dispersion of logarithmic dependencies of power spectra) parameters are presented. They characterize the coordinate distributions of phase shifts between the orthogonal components of the amplitude in the points of laser images of blood plasma smears and pathological changes in the mammary gland tissue. The diagnostic criteria of breast cancer nascency are determined.

    DeSantis, Carol; Siegel, Rebecca; Bandi, Priti; Jemal, Ahmedin

    2011-01-01

    In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including trends in incidence, mortality, survival, and screening. Approximately 230,480 new cases of invasive breast cancer and 39,520 breast cancer deaths are expected to occur among US women in 2011. Breast cancer incidence rates were stable among all racial/ethnic groups from 2004 to 2008. Breast cancer death rates have been declining since the early 1990s for all women except American Indians/Alaska Natives, among whom rates have remained stable. Disparities in breast cancer death rates are evident by state, socioeconomic status, and race/ethnicity. While significant declines in mortality rates were observed for 36 states and the District of Columbia over the past 10 years, rates for 14 states remained level. Analyses by county-level poverty rates showed that the decrease in mortality rates began later and was slower among women residing in poor areas. As a result, the highest breast cancer death rates shifted from the affluent areas to the poor areas in the early 1990s. Screening rates continue to be lower in poor women compared with non-poor women, despite much progress in increasing mammography utilization. In 2008, 51.4% of poor women had undergone a screening mammogram in the past 2 years compared with 72.8% of non-poor women. Encouraging patients aged 40 years and older to have annual mammography and a clinical breast examination is the single most important step that clinicians can take to reduce suffering and death from breast cancer. Clinicians should also ensure that patients at high risk of breast cancer are identified and offered appropriate screening and follow-up. Continued progress in the control of breast cancer will require sustained and increased efforts to provide high-quality screening, diagnosis, and treatment to all segments of the population.

    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%. The same HPV type was identified in both the benign and subsequent breast cancer in 15 patients. 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

    A new microwave imaging method that uses microwave contrast agents is presented for the detection and localization of breast tumours. The method is based on the reconstruction of breast surface impedance through a measured scattered field. The surface impedance modelling allows for representing the electrical properties of the breasts in terms of impedance boundary conditions, which enable us to map the inner structure of the breasts into surface impedance functions. Later a simple quantitative method is proposed to screen breasts against malignant tumours where the detection procedure is based on weighted cross correlations among impedance functions. Numerical results demonstrate that the method is capable of detecting small malignancies and provides reasonable localization.

    Full Text Available Hyperthermia is potentially an effective method for the treatment of cancer, especially breast cancer tumors. One of the most attractive attributes of hyperthermia is the possibility of providing therapeutic benefit noninvasively, minimizing side effects. To be effective, a hyperthermia treatment must selectively heat the cancerous tissue, elevating the temperature in the tumor without exposing healthy tissue to excessive temperature elevations. In this paper, a suggested simple model of Annular Phased Array (APA using eight half wavelength linear dipoles is presented. New software (COMSOL MULTIPHYSICS is used to calculate the temperature distribution inside a model of a three layered breast (skin, breast tissue, and tumor. In addition, the effect of changing the amplitude and phases of the array elements on the temperature distributions and the conditions on the values of the phases are demonstrated in order to achieve the objective of hyperthermia for breast tumor treatment.

    Highlights: • The addition of supplemental US to mammography depicted additional 5.0 cancers per 1000 postoperative women. • Positive biopsy rate of mammography-detected lesions was 66.7% (4 of 6) and that of US-detected lesions was 40.0% (6 of 15). • US can be helpful to detect mammographically occult breast cancer in the contralateral breast in women with previous history of cancer and dense breast. - Abstract: Objective: To determine whether supplemental screening ultrasound (US) to mammography could improve cancer detection rate of the contralateral breast in patients with a personal history of breast cancer and dense breasts. Materials and methods: During a one-year study period, 1314 screening patients with a personal history of breast cancer and dense breasts simultaneously underwent mammography and breast US. BI-RADS categories were given for mammography or US-detected lesions in the contralateral breast. The reference standard was histology and/or 1-year imaging follow-up, and the cancer rate according to BI-RADS categories and cancer detection rate and positive biopsy rate according to detection modality were analyzed. Results: Of 1314 patients, 84 patients (6.4%) were categorized as category 3 with one interval cancer and one cancer which was upgraded to category 4A after 6-month follow-up US (2.5% cancer rate, 95% CIs 1.5–9.1%). Fifteen patients (1.1%) had category 4A or 4B lesions in the contralateral breast. Four lesions were detected on mammography (two lesions were also visible on US) and 11 lesions were detected on US and 5 cancers were confirmed (33.3%, 95% CIs 15.0–58.5%). Six patients (0.5%) had category 4C lesions, 2 detected on mammography and 4 on US and 4 cancers were confirmed (66.7%, 95% CIs 29.6–90.8%). No lesions were categorized as category 5 in the contralateral breast. Cancer detection rate by mammography was 3.3 per 1000 patients and that by US was 5.0 per 1000 patients, therefore overall cancer detection rate by

    Over the years several analytical methods have been proposed for the measurement of glucose metabolism using fluorine-18 fluorodeoxyglucose ([{sup 18}F]FDG) and positron emission tomography (PET). The purpose of this study was to evaluate which of these (often simplified) methods could potentially be used for clinical response monitoring studies in breast cancer. Prior to chemotherapy, dynamic [{sup 18}F]FDG scans were performed in 20 women with locally advanced (n=10) or metastasised (n=10) breast cancer. Additional PET scans were acquired after 8 days (n=8), and after one, three and six courses of chemotherapy (n=18, 10 and 6, respectively). Non-linear regression (NLR) with the standard two tissue compartment model was used as the gold standard for measurement of [{sup 18}F]FDG uptake and was compared with the following methods: Patlak graphical analysis, simplified kinetic method (SKM), SUV-based net influx constant (''Sadato'' method), standard uptake value [normalised for weight, lean body mass (LBM) and body surface area (BSA), with and without corrections for glucose (g)], tumour to non-tumour ratio (TNT), 6P model and total lesion evaluation (TLE). Correlation coefficients between each analytical method and NLR were calculated using multilevel analysis. In addition, for the most promising methods (Patlak, SKM, SUV{sub LBMg} and SUV{sub BSAg}) it was explored whether correlation with NLR changed with different time points after the start of therapy. Three methods showed excellent correlation (r>0.95) with NLR for the baseline scan: Patlak10-60 and Patlak10-45 (r=0.98 and 0.97, respectively), SKM40-60 (r=0.96) and SUV{sub LBMg} (r=0.96). Good correlation was found between NLR and SUV-based net influx constant, TLE and SUV{sub BSAg} (0.90methods, correlation with NLR

    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.

  17. Targeting Breast Cancer Metastasis

    OpenAIRE

    2015-01-01

    Metastasis is the leading cause of breast cancer-associated deaths. Despite the significant improvement in current therapies in extending patient life, 30–40% of patients may eventually suffer from distant relapse and succumb to the disease. Consequently, a deeper understanding of the metastasis biology is key to developing better treatment strategies and achieving long-lasting therapeutic efficacies against breast cancer. This review covers recent breakthroughs in the discovery of various me...

    1998-01-01

    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.

    Full Text Available Abstract Background Male breast cancer is a rare but aggressive and devastating disease. This disease presents at a later stage and in a more advanced fashion than its female counterpart. The immunophenotype also appears to be distinct when compared to female breast cancer. Angiogenesis plays a permissive role in the development of a solid tumor and provides an avenue for nutrient exchange and waste removal. Recent scrutiny of angiogenesis in female breast cancer has shown it to be of significant prognostic value. It was hypothesized that this holds true in invasive ductal carcinoma of the male breast. In the context of male breast cancer, we investigated the relationship of survival and other clinico-pathological variables to the microvascular density of the tumor tissue. Methods Seventy-five cases of primary male breast cancer were identified using the records of the Saskatchewan Cancer Agency over a period of 26 years. Forty-seven cases of invasive ductal carcinoma of the male breast had formalin-fixed paraffin-embedded tissue blocks that were suitable for this study. All cases were reviewed. Immunohistochemical staining was performed for the angiogenic markers (cluster designations 31 (CD31, 34 (CD34 and 105 (CD105, von Willebrand factor (VWF, and vascular endothelial growth factor (VEGF. Microvascular density (MVD was determined using average, centre, and highest microvessel counts (AMC, CMC, and HMC, respectively. Statistical analyses compared differences in the distribution of survival times and times to relapse between levels of MVD, tumor size, node status and age at diagnosis. In addition, MVD values were compared within each marker, between each marker, and were also compared to clinico-pathological data. Results Advanced age and tumor size were related to shorter survival times. There were no statistically significant differences in distributions of survival times and times to relapse between levels of MVD variables. There was no

    High income, high socioeconomic status, and affluence increase breast cancer incidence. Socioeconomic status in USA breast cancer studies has been assessed by block-group socioeconomic measures. A block group is a portion of a census tract with boundaries that segregate, as far as possible, socioeconomic groups. In this study, we used US Census income data instead of block groups to gauge socioeconomic status of breast cancer patients in relationship with incidence, prognostic markers, and survival. US state breast cancer incidence and mortality data are from the U.S. Cancer Statistics Working Group, United States Cancer Statistics: 1999-2011. Three-Year-Average Median Household Income by State, 2010 to 2012, is from the U.S. Census Bureau, Current Population Survey, 2011 to 2013 Annual Social and Economic Supplements. County incomes are from the 2005-2009 American Community Survey of the U.S. Census Bureau. The American Community Survey is an ongoing statistical survey that samples a small percentage of the population yearly. Its purpose is to provide communities the information they need to plan investments and services. Breast cancer county incidence and survival data are from the National Cancer Institute's Surveillance, Epidemiology and End Results Program (SEER) data base. We analyzed SEER data from 198 counties in California, Connecticut, Georgia, Hawaii, Iowa, New Mexico, Utah, and Washington. SEER uses the Collaborative Stage (CS) Data Collection System. We have retained the SEER CS variables. There was a significant relationship of income with breast cancer incidence in 50 USA states and the District of Columbia in White women (r = 0.623, p breast cancer. Income was not correlated with 5-year survival of Black race (p = 0.364) or other races (p = 0.624).

    Full Text Available Steven Lehrer, Sheryl Green, John A Martignetti, Kenneth E Rosenzweig Departments of Radiation Oncology and Genetics and Genomic Sciences, Icahn School of Medicine at Mount Sinai, New York, NY, USA Background: The risk of thyroid cancer is known to be slightly increased in women after treatment for breast cancer. 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.

    Full Text Available Breast cancer has become a common factor now-a-days. Despite the fact, not all general hospitalshave the facilities to diagnose breast cancer through mammograms. Waiting for diagnosing a breastcancer for a long time may increase the possibility of the cancer spreading. Therefore a computerizedbreast cancer diagnosis has been developed to reduce the time taken to diagnose the breast cancer andreduce the death rate. This paper summarizes the survey on breast cancer diagnosis using various machinelearning algorithms and methods, which are used to improve the accuracy of predicting cancer. This surveycan also help us to know about number of papers that are implemented to diagnose the breast cancer.

    2012-01-01

    Full Text Available Machine learning has increasingly been used with microarray gene expression data and for the development of classifiers using a variety of methods. However, method comparisons in cross-study datasets are very scarce. This study compares the performance of seven classification methods and the effect of voting for predicting metastasis outcome in breast cancer patients, in three situations: within the same dataset or across datasets on similar or dissimilar microarray platforms. Combining classification results from seven classifiers into one voting decision performed significantly better during internal validation as well as external validation in similar microarray platforms than the underlying classification methods. When validating between different microarray platforms, random forest, another voting-based method, proved to be the best performing method. We conclude that voting based classifiers provided an advantage with respect to classifying metastasis outcome in breast cancer patients.

    2014-07-01

    Ultra-wideband (UWB) microwave imaging is a promising method for breast cancer detection based on the large contrast of electric parameters between the malignant tumor and its surrounded normal breast organisms. In the case of multiple tumors being present, the conventional imaging approaches may be ineffective to detect all the tumors clearly. In this paper, a progressive processing method is proposed for detecting more than one tumor. The method is divided into three stages: primary detection, refocusing and image optimization. To test the feasibility of the approach, a numerical breast model is developed based on the realistic magnetic resonance image (MRI). Two tumors are assumed embedded in different positions. Successful detection of a 3.6 mm-diameter tumor at a depth of 42 mm is achieved. The correct information of both tumors is shown in the reconstructed image, suggesting that the progressive processing method is promising for multi-tumor detection.

    The various risk factors for breast cancer have been recognized for many years. A table lists these established breast cancer risk factors together with the approximate magnitude of the increase in risk associated with them. Breast cancer incidence rates increase with age throughout the life span in Western countries, although the rate of increase is greater up to age 50 years than after 50 years. Breast cancer is more common among women in upper rather than lower social classes, among women who never have been married, among women living in urban areas, among women living in the northern US than in the southern US, and among whites than blacks, at least among those over age 50. Women in North American and Northern European countries have the highest risk for breast cancer, women in Southern European and Latin American countries are at intermediate risk, and women in Africa and Asian countries have the lowest risk. Yet, rapid rates of increase in incident rates have been noted in recent years in many Asian, Central European, and some South American countries. The later the age at which a woman has her 1st full-term pregnancy, the higher her risk for breast cancer; the earlier the age at menarche and the later the age at menopause the higher the risk; and among women who have a premenopausal oophorectomy, the earlier the age at which this occurs the lower the risk. Among postmenopausal women, obesity is associated with an increase in risk. Lactation is negatively associated with subsequent breast cancer risk. Some current research is considering potential risk factors that have not been well studied in the past, including alcohol consumption, cigarette smoking, caffeine consumption, exposure to diethylstilbestrol (DES), emotional stress, exposure to electric power, and lack of physical activity. Other areas of current research reviewed here include radiation, mammographic parenchymal patterns, a high-fat diet, use of oral contraceptives (OCs), use of estrogen

    Studies on health behaviors have observed several barriers to breast cancer screening, including lack of breast cancer knowledge, distrust of health care providers, and long waiting times to be screened or to receive screening results. We conducted a nested case-control study among a subsample of 200 women 21 years of age and older [100 patients (cases)], who had been diagnosed with breast cancer, and 100 controls, who were screened and found to be free of breast cancer), all residing in the Toluca metropolitan area in central Mexico. We examined how knowledge of breast cancer screening guidelines, perceptions of screening methods, and quality of health care influenced the use of breast cancer screening among study participants. Our study found that the most important factor associated with the decision to have breast cancer screenings was having a positive perception of the quality of care provided by the local health care centers, such as having competent clinic personnel, sufficient screening equipment, and reasonable waiting times to receive screening and to receive the screening results. Therefore, individual health care centers need to focus on the patients' perception of the services received by optimizing the care provided and, in so doing, increase the rates of early diagnosis and reduce the rate of mortality from breast cancer as well as its associated treatment costs.

    Objective This descriptive study was designed to determine the impact of nurses’ healthy lifestyle behaviors on utilization from breast cancer early diagnosis methods. Materials and Methods The study was carried out with 236 (41.7%) nurses who agreed to participate out of 565 nurses who work in a university hospital from February 12th to February 15th 2011. Healthy Lifestyle Behaviors Scale was collected by using a questionnaire consisting of 41 questions. The Healthy Lifestyle Behaviors Scale was improved by Walker, Sechrist and Pender (1987) and was adapted to Turkish by Esin (1997). The data was evaluated by percentage calculation, one -way ANOVA, t-test and Tukey’s test. Results The mean Healthy Lifestyle Behaviors Scale score was 129.09±19.82, the mean scores subscale scores of self-actualization, health responsibility, exercise, nutrition, interpersonal support and stress management were 38.52±6.28, 24.95±5.39, 9.41±3.24, 16.99±3.29, 21.22±3.39 and 17.99±3.66 respectively. It was found that Healthy Lifestyle Behaviors Scale total score was higher in nurses with sufficient level of breast cancer knowledge (F=13.115, p=0.000), who perform regular BSE (t=3.191, p=0.002) and who attended training on breast cancer (t=3030, p=0.003). Conclusion It was determined that although the mean total score of nurse’s Healthy Lifestyle Behaviors Scale and their information on breast cancer prevention were above average, the utilization of breast cancer early detection services was not at the expected levels.

    Purpose: Exercise decreases breast cancer risk and disease recurrence, but the underlying mechanisms are unknown. Training adaptations in systemic factors have been suggested as mediating causes. We aimed to examine if systemic adaptations to training over time, or acute exercise responses......, in breast cancer survivors could regulate breast cancer cell viability in vitro. Methods: Blood samples were collected from breast cancer survivors, partaking in either a 6-month training intervention or across a 2 h acute exercise session. Changes in training parameters and systemic factors were evaluated...... and pre/post exercise-conditioned sera from both studies were used to stimulate breast cancer cell lines (MCF-7, MDA-MB-231) in vitro. Results: Six months of training increased VO2peak (16.4 %, p

  15. Progestins and breast cancer.

    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

    Breast cancer makes up a quarter of all cancer in women, which is why research into new diagnostic methods and sample preparations need to be developed at an accelerated pace. Researchers are looking for diagnostic tools to detect when an individual has cancer cells and use that information to see what measurements and approaches can be used to take further diagnostic steps. The most common method of sample preparation is the imbibing of tumor tissue in paraffin, which can produce a background for spectroscopic measurements in the range of 500-3500 cm-1. In this study we demonstrated that proper preparation of paraffin-embedded specimens and the measurement methodology can eliminate paraffin vibration, as was done in the work Depciuch et al. 2015. Thanks to this spectroscopic technique there may become a reliable and accurate method of diagnosing breast cancer based on the evidence found from the prepared samples. The study compared the results obtained through Raman spectroscopy and FTIR (Fourier Transform Infrared) measurements of healthy and cancerous breast tissues that were either embedded in paraffin or deparaffinized. The resulting spectrum and accurate analysis led to the conclusion that the appropriate measurement of the background and the elimination of peaks from the paraffin had the greatest impact on the reliability of results. Furthermore, after the accurate, detailed studies FTIR and Raman spectroscopy on samples of breast tissue that were deparaffinized or embedded in paraffin, including a complete analysis of the peak after transformation Kramers-Kröning (KK), it was found that sample preparation did not affect the result obtained by measuring the reflectance in the mid-infrared range, and that this only had a minimal effect relating to the intensity obtained by the measurement of the Raman peak. Only in special cases, when Raman spectroscopic methods are used for research to find the peculiarities of the spectra, are deparaffinization recommended

    Although mammography and treatment advances have led to declines in breast cancer mortality in the United States, breast cancer remains a major cause of morbidity and mortality. Breast cancer in young women is associated with increased mortality and current methods of detecting breast cancers in this group of women have known limitations. Tools for accurately assessing personal breast cancer risk in young women are needed to identify those women who would benefit the most from earlier intervention. Proteomic analysis of breast milk could identify biomarkers of breast cancer risk and provide a tool for identifying women at increased risk. A preliminary analysis of milk from four women provides a proof of concept for using breast milk to assess breast cancer risk.

    Full Text Available BACKGROUND Breast cancer is the most common malignant tumour in women worldwide. The relationship between breast cancer and thyroid disease is a controversy. Many of the studies showed hypothyroidism as the commonly found thyroid abnormality in breast cancer. [1] There is considerable evidence for an increased risk of thyroid and breast cancer in patients with iodine deficiency. This ability of iodine to reduce the risk of breast cancer is attributed to the ability of iodine and its compounds to induce apoptosis so that appropriate cell death occurs. Instead, in the absence of optimum level of iodine in the body the transformed cells continue to grow and divide resulting in cancer. AIMS 1. To find out the association of thyroid hormones and breast cancer in early breast cancer patients. 2. To find out the association of thyroid peroxidase antibodies in early breast cancer patients. Settings Cases: 82 breast cancer patients in early stage who attended the breast clinic. Controls: 82 age matched controls (Between 25-80 years. Design: Case control study. MATERIALS AND METHOD In this study, investigated for thyroid function test (T3, T4, TSH and thyroid peroxide antibody level in 82 early breast cancer patients. STATISTICAL ANALYSIS SPSS 16. RESULTS Statistically significant low T4 and high TSH in breast cancer patients, along with elevated thyroid peroxidase antibody. CONCLUSION Compared to hyperthyroidism, hypothyroidism was found to be clinically significant in breast cancer patients

    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

    Cadmium is a known human lung carcinogen, although some studies indicate a link between cadmium exposure and human breast cancer. The objective of this study was to assess cadmium concentration in breast tissue samples of patients with breast cancer and benign breast tumor. MATERIAL AND METHODS. The concentration of cadmium was determined in breast tissue samples of 21 breast cancer and 19 benign tumor patients. Two samples of breast tissue from each patient, i.e. tumor and normal tissue close to tumor, were taken for the analysis. Cadmium was determined by atomic absorption spectrometry (Perkin-Elmer, Zeeman 3030). RESULTS. In patients with breast cancer, the mean cadmium concentration was 33.1 ng/g (95% CI, 21.9-44.4) in malignant breast tissue and 10.4 ng/g (95% CI, 5.6-15.2) in normal breast tissue (P=0.002). In patients with benign tumor, the corresponding values were 17.5 ng/g (95% CI, 8.4-26.5) and 11.8 ng/g (95% CI, 5.1-18.5) (P=0.3144). There was a statistically significant difference in cadmium concentration between malignant and benign breast tissues (P=0.009). CONCLUSION. The data obtained show that cadmium concentration is significantly higher in malignant breast tissue as compared with normal breast tissue of the same women or benign breast tissue. Further studies are necessary to determine the association between cadmium concentration in malignant breast tissue and estrogen receptor level, and smoking.

    A totally satisfying concept of treatment is not easy to formulate from the complex and often conflicting results of local therapeutic interventions for breast cancer. It seems evident that clinically occult cancer is often beyond the pale of both resection and irradiation at primary treatment, particularly when cancer is found in regional lymph nodes. Despite all combinations of local treatment, the ultimate risk of failure correlates more closely with the stage of the disease at the time of treatment than with the particular form of treatment. Thus the extent of disease must be considered the major, perhaps the ultimate determinant of prognosis. Because, under controlled conditions, several therapeutic alternatives have appeared to provide virtually identical end results in terms of survival and ultimate dissemination of the disease, the adequacy of control within the field of treatment may, in fact, be the most meaningful end result of local treatment. The experience that has accumulated with treatment of breast cancer supports the thesis that removal of the breast accomplishes all that can be achieved in terms of curing the disease, and wider treatment with surgery or irradiation serves only to improve the prospects for local control. Halsted demonstrated this principle with his radical mastectomy and it still seems to be the case. This fact provides further impetus for detecting and treating cancer while it is still localized to the breast. With these generalizations in mind some empirical observations can be added. An anatomic fact is that multiple microscopic foci of cancer that are not evident clinically are often present in the mammary parenchyma. Undisturbed, at least some, and perhaps eventually all, of these foci of cancer progress to become clinical cancers. Thorough removal of the entire breast (the entire mammary parenchyma) eliminates this particular hazard and, one may presume, terminates the disease if it is still limited to the breast. Removal of

    2015-11-01

    Full Text Available The purpose of the present study was to establish a non-surgical breast-conserving treatment (BCT using KORTUC II radiosensitization treatment. A new radiosensitizing agent containing 0.5% hydrogen peroxide and 0.83% sodium hyaluronate (a CD44 ligand has been developed for intra-tumoral injection into various tumors. This new method, named KORTUC II, was approved by our local ethics committee for the treatment of breast cancer and metastatic lymph nodes. A total of 72 early-stage breast cancer patients (stage 0, 1 patient; stage I, 23; stage II, 48 were enrolled in the KORTUC II trial after providing fully informed consent. The mean age of the patients was 59.7 years. A maximum of 6 mL (usually 3 mL for tumors of less than approximately 3 cm in diameter of the agent was injected into breast tumor tissue twice a week under ultrasonographic guidance. For radiotherapy, hypofraction radiotherapy was administered using a tangential fields approach including an ipsilateral axillary region and field-in-field method; the energy level was 4 MV, and the total radiation dose was 44 Gy administered as 2.75 Gy/fraction. An electron boost of 3 Gy was added three times. Treatment was well tolerated with minimal adverse effects in all 72 patients. No patients showed any significant complications other than mild dermatitis. A total of 24 patients under 75 years old with stage II breast cancer underwent induction chemotherapy (EC and/or taxane prior to KORTUC II treatment, and 58 patients with estrogen receptor-positive tumors also received hormonal therapy following KORTUC II. The mean duration of follow-up as of the end of September 2014 was 51.1 months, at which time 68 patients were alive without any distant metastases. Only one patient had local recurrence and died of cardiac failure at 6.5 years. Another one patient had bone metastases.

    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.

    Background Screening clinical breast examination (cbe) is controversial; the use of cbe is declining not only as a screening tool, but also as a diagnostic tool. In the present study, we aimed to assess the value of cbe in breast cancer detection in a tertiary care centre for breast diseases. Methods This retrospective study of all breast cancers diagnosed between July 1999 and December 2010 at our centre categorized cases according to the mean of detection (cbe, mammography, or both). A cbe was considered “abnormal” in the presence of a mass, nipple discharge, skin or nipple retraction, edema, erythema, peau d’orange, or ulcers. Results During the study period, a complete dataset was available for 6333 treated primary breast cancers. Cancer types were ductal carcinoma in situ (15.3%), invasive ductal carcinoma (75.7%), invasive lobular carcinoma (9.0%), or others (2.2%). Of the 6333 cancers, 36.5% (n = 2312) were detected by mammography alone, 54.8% (n = 3470) by mammography and cbe, and 8.7% (n = 551) by physician-performed cbe alone (or 5.3% if considering ultrasonography). Invasive tumours diagnosed by cbe alone were more often triple-negative, her2-positive, node-positive, and larger than those diagnosed by mammography alone (p < 0.05). Conclusions A significant number of cancers would have been missed if cbe had not been performed. Compared with cancers detected by mammography alone, those detected by cbe had more aggressive features. Clinical breast examination is a very low-cost test that could improve the detection of breast cancer and could prompt breast ultrasonography in the case of a negative mammogram. PMID:27536182

    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.

  3. Breast cancer risk factors

    Full Text Available 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.

  4. Estimation of volumetric breast density for breast cancer risk prediction

    Mammographic density (MD) has been shown to be a strong risk predictor for breast cancer. Compared to subjective assessment by a radiologist, computer-aided analysis of digitized mammograms provides a quantitative and more reproducible method for assessing breast density. However, the current methods of estimating breast density based on the area of bright signal in a mammogram do not reflect the true, volumetric quantity of dense tissue in the breast. A computerized method to estimate the amount of radiographically dense tissue in the overall volume of the breast has been developed to provide an automatic, user-independent tool for breast cancer risk assessment. The procedure for volumetric density estimation consists of first correcting the image for inhomogeneity, then performing a volume density calculation. First, optical sensitometry is used to convert all images to the logarithm of relative exposure (LRE), in order to simplify the image correction operations. The field non-uniformity correction, which takes into account heel effect, inverse square law, path obliquity and intrinsic field and grid non- uniformity is obtained by imaging a spherical section PMMA phantom. The processed LRE image of the phantom is then used as a correction offset for actual mammograms. From information about the thickness and placement of the breast, as well as the parameters of a breast-like calibration step wedge placed in the mammogram, MD of the breast is calculated. Post processing and a simple calibration phantom enable user- independent, reliable and repeatable volumetric estimation of density in breast-equivalent phantoms. Initial results obtained on known density phantoms show the estimation to vary less than 5% in MD from the actual value. This can be compared to estimated mammographic density differences of 30% between the true and non-corrected values. Since a more simplistic breast density measurement based on the projected area has been shown to be a strong indicator

    Directory of Open Access Journals (Sweden)

    Full Text Available In the normal breast, cellular structures change cyclically in response to ovarian hormones. Cell proliferation, apoptosis, invasion, and differentiation are integral processes that are precisely regulated. Normal epithelial cells depend on the formation of intercellular adhesion contacts to form a continuous sheet of stratifying cell layers that are attached to one and other horizontally and vertically. Cells migrate by extending membrane protrusions to explore the extracellular space locating their targets in a chemotactic manner. The formation of cell protrusions is driven by the assembly of actin filaments at the leading edge. Reorganisation is regulated by a highly integrated signalling cascade that transduces extracellular stimuli to the actin filaments. This signalling cascade is governed by GTPases which act as molecular switches leading to actin polymerisation and the formation of filopodia and lamellipodia. This process is linked to downstream molecules known collectively as WASP proteins, which, in the presence of cortactin, form a complex leading to nucleation and formation of branched filaments. In breast cancer, the cortactin is over expressed leading to increased cellular motility and invasiveness. This hugely complex and integrated signalling cascade transduces extracellular stimuli. There are multiple genes related to cell motility which are dysregulated in human breast cancers.

    A non-invasive computer-aided-theragnosis (CAT) system was developed for the early assessment of responses to neoadjuvant chemotherapy in patients with locally advanced breast cancer. The CAT system was based on quantitative ultrasound spectroscopy methods comprising several modules including feature extraction, a metric to measure the dissimilarity between "pre-" and "mid-treatment" scans, and a supervised learning algorithm for the classification of patients to responders/non-responders. One major requirement for the successful design of a high-performance CAT system is to accurately measure the changes in parametric maps before treatment onset and during the course of treatment. To this end, a unified framework based on Hilbert-Schmidt independence criterion (HSIC) was used for the design of feature extraction from parametric maps and the dissimilarity measure between the "pre-" and "mid-treatment" scans. For the feature extraction, HSIC was used to design a supervised dictionary learning (SDL) method by maximizing the dependency between the scans taken from "pre-" and "mid-treatment" with "dummy labels" given to the scans. For the dissimilarity measure, an HSIC-based metric was employed to effectively measure the changes in parametric maps as an indication of treatment effectiveness. The HSIC-based feature extraction and dissimilarity measure used a kernel function to nonlinearly transform input vectors into a higher dimensional feature space and computed the population means in the new space, where enhanced group separability was ideally obtained. The results of the classification using the developed CAT system indicated an improvement of performance compared to a CAT system with basic features using histogram of intensity.

    The female breast cancer is a relevant health issue among female population, due its incidence and remarkable effects in the biological, psychological and social levels. Its early diagnosis is important because it allows more effective treatments and enhances changes of cure, even allowing conservative surgical procedures. To make this possible it is essential the periodic breast imaging exams. The available imaging methods to date are: mammography, ultrasonography, thermography, nuclear medicine, computed tomography and MRI. All these methods have their advantages and disadvantages, applications and limitations and some are even in experimental stages. These methods must exercised in association to become more effective. Mammography is still, beyond and doubt the elected breast exam. even though imperfect. It must be performed repeatedly at periodic intervals depending upon the intrinsic conditions of the patient. The other methods complement the mammographic findings, clearing some of them. In this paper, the imaging methods available in our environmental for detected diagnosis of the early breast cancer are analyzed with emphasis in mammography and ultrasonography. Their advantages, disadvantages, indications and limitations are discussed. (author). 205 refs., 12 figs.

    Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) is used to find the structural differences between cancerous breast cells (MCF-7 line) and normal breast cells (MCF-12F line). Gold nanoparticles were prepared and the hydrodynamic diameter of the gold nanoparticles found to be 38.45 nm. The Gold nanoparticles were exposed to both MCF-7 and MCF-12F cells from lower to higher concentrations. Spectroscopic studies founds nanoparticles were within the cells, and increasing the nanoparticles concentration inside the cells also resulted in sharper IR peaks as a result of localized surface Plasmon resonance. Asymmetric and symmetric stretching and bending vibrations between phosphate, COO-, CH2 groups were found to give negative shifts in wavenumbers and a decrease in peak intensities when going from noncancerous to cancerous cells. Cellular proteins produced peak assignments at the 1542 and 1644 cm(-1) wavenumbers which were attributed to the amide I and amide II bands of the polypeptide bond of proteins. Significant changes were found in the peak intensities between the cell lines in the spectrum range from 2854-2956 cm(-1). Results show that the concentration range of gold nanoparticles used in this research showed no significant changes in cell viability in either cell line. Therefore, we believe ATR-FTIR and gold nanotechnology can be at the forefront of cancer diagnosis for some time to come.

    INTRODUCTION: Digoxin use is associated with increased incidence of breast and uterus cancers. We postulated that digoxin use might affect tumor characteristics and increase relapse risk in women with breast cancer. METHODS: Incident breast cancer cases in Danish women (n = 49,312; 1995 to 2008......) were identified. Analyses were conducted in women 20 to 74 years old. Relapse hazard ratios (HR) were compared in women using and not using digoxin, adjusting for age, calendar period, protocol, tumor size, nodal involvement, histology grade, estrogen-receptor (ER) status, and anti-estrogen therapy...... in 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...

    Full Text Available Abstract Background Seroma formation is the most frequent postoperative complication after breast cancer surgery. We carried out a study to investigate the effect of various demographic, clinical and therapeutic variables on seroma formation. Patients and methods A retrospective cross sectional study of patients who underwent surgical therapy for breast cancer with either modified radical mastectomy (MRM or breast preservation (BP was carried out. The demographic data and clinical information were extracted from case records. Seroma formation was studied in relation to age, type of surgery, tumor size, nodal involvement, preoperative chemotherapy, surgical instrument (electrocautery or scalpel, use of pressure garment, and duration of drainage. The multiple logistic regression analysis was performed to estimate odds ratios. Results A total of 158 patients with breast cancer were studied. The mean age of the patients was 46.3 years (SD ± 11.9. Seventy-three percent underwent modified radical mastectomy and the remaining 27% received breast preservation surgery. Seroma occurred in 35% of patients. In multivariate logistic regression analysis an association of postoperative seroma formation was noted with modified radical mastectomy (OR = 2.83, 95% CI 1.01–7.90, P = 0.04. No other factor studied was found to significantly effect the seroma formation after breast cancer surgery.

  8. Aluminium, antiperspirants and breast cancer.

    Science.gov (United States)

    Darbre, P D

    2005-09-01

    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.

    Breast augmentation surgery involving the use of implants has been one of the most popular plastic surgical procedures for decades. As the multi-million female population who received breast implants ages, the risk of cancer is increasing rapidly, therefore the incidence of malignant disease in association with breast implants will increase as well. Although there is no relationship between tumor development and implants, these cases require special considerations in diagnostics, therapy and follow-up methods. Appropriate multidisciplinary treatment of tumors in augmented breasts corresponding with modern oncoplastic principles can only be accomplished based on adequate oncological, breast and plastic surgical knowledge. Supposing a possible increase of this condition in Hungary, too, authors provide a wide review of the literature on the special oncological and esthetic considerations, for the first time in Hungarian language.

  12. Attitudes and Stereotypes in Lung Cancer versus Breast Cancer.

    Full Text Available Societal perceptions may factor into the high rates of nontreatment in patients with lung cancer. To determine whether bias exists toward lung cancer, a study using the Implicit Association Test method of inferring subconscious attitudes and stereotypes from participant reaction times to visual cues was initiated. Participants were primarily recruited from an online survey panel based on US census data. Explicit attitudes regarding lung and breast cancer were derived from participants' ratings (n = 1778 regarding what they thought patients experienced in terms of guilt, shame, and hope (descriptive statements and from participants' opinions regarding whether patients ought to experience such feelings (normative statements. Participants' responses to descriptive and normative statements about lung cancer were compared with responses to statements about breast cancer. Analyses of responses revealed that the participants were more likely to agree with negative descriptive and normative statements about lung cancer than breast cancer (P<0.001. Furthermore, participants had significantly stronger implicit negative associations with lung cancer compared with breast cancer; mean response times in the lung cancer/negative conditions were significantly shorter than in the lung cancer/positive conditions (P<0.001. Patients, caregivers, healthcare providers, and members of the general public had comparable levels of negative implicit attitudes toward lung cancer. These results show that lung cancer was stigmatized by patients, caregivers, healthcare professionals, and the general public. Further research is needed to investigate whether implicit and explicit attitudes and stereotypes affect patient care.

    Full Text Available Several of the active compounds in foods, poisons, drugs, and industrial chemicals may, by epigenetic mechanisms, increase or decrease the risk of breast cancers. Enzymes that are involved in DNA methylation and histone modifications have been shown to be altered in several types of breast and other cancers resulting in abnormal patterns of methylation and/or acetylation. Hypermethylation at the CpG islands found in estrogen response element (ERE promoters occurs in conjunction with ligand-bonded alpha subunit estrogen receptor (Erα dimers wherein the ligand ERα dimer complex acts as a transcription factor and binds to the ERE promoter. Ligands could be 17-β-estradiol (E2, phytoestrogens, heterocyclic amines, and many other identified food additives and heavy metals. The dimer recruits DNA methyltransferases which catalyze the transfer of methyl groups from S-adenosyl-L-methionine (SAM to 5′-cytosine on CpG islands. Other enzymes are recruited to the region by ligand-ERα dimers which activate DNA demethylases to act simultaneously to increase gene expression of protooncogenes and growth-promoting genes. Ligand-ERα dimers also recruit histone acetyltransferase to the ERE promoter region. Histone demethylases such as JMJD2B and histone methyltransferases are enzymes which demethylate lysine residues on histones H3 and/or H4. This makes the chromatin accessible for transcription factors and enzymes.

    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.

    Full Text Available Purpose: We propose a process of quality assurance to validate and implement the single isocenter technique for breast cancer radiotherapy. We evaluated the dosimetric and temporal gains using the single isocenter technique compared to classic source to skin distance (SSD technique. Methods: 6 patients of breast cancer localization were studied. For each patient 2 treatment plans were generated. In plan 1 the dose was calculated using SSD technique. In plan 2 the dose was calculated using single isocenter technique. To implement the plan 2 a dosimetric analysis including monitor units (MU, isodose curves, cumulative and differential dose volume histograms cDVH, dDVH respectively, coverage index, conformity index for planning target volume were used. The measurements using a PMMA phantom consist of measuring point dose by an ionization chamber and 2D dose distributions using 2D diodes arrays. Wilcoxon signed rank and Spearman’s tests were used to calculate p-value and correlation coefficient, respectively.Results: The single isocenter technique reduced the MU by average on -30.1 ± 13.6%, (p = 0.03. We observed an improvement with statistical significance between the two techniques for the mean dose, minimum dose and volume receiving 95% of the prescribed dose without over-dosage. The analysis for dDVH showed that the dose distribution in the target volume calculated in the single isocenter technique is more homogeneous than the SSD technique. Wilcoxon test showed that the two treatment plans had the same quality (p > 0.05. The difference between calculated and measured dose was within 2.4 ± 3.3% for absolute point dose and the percentage of points passing gamma criteria was on average 99.8 ± 0.2%. Conclusion: This method provides a quantitative evaluation and comparison of the two irradiation techniques for breast cancer and the consequences of the technical change on dose calculation.

    Surgical therapy for occult breast cancer has traditionally centered on mastectomy; however, breast conservation with whole breast radiotherapy followed by axillary lymph node dissection has shown equivalent results. Patients with breast cancer in pregnancy can be safely and effectively treated; given a patient's pregnancy trimester and stage of breast cancer, a clinician must be able to guide therapy accordingly. Male breast cancer risk factors show strong association with BRCA2 mutations, as well as Klinefelter syndrome. Several retrospective trials of surgical therapy in stage IV breast cancer have associated a survival advantage with primary site tumor extirpation.

    Full Text Available Murtaza Akhtar, Subhrajit Dasgupta, Murtuza Rangwala Department of Surgery, NKP Salve Institute of Medical Sciences and Research Centre, Nagpur, Maharashtra, India Introduction: Breast cancer is the most common female cancer in the world. 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

    Full Text Available Background: Breast and cervical cancers are two major cancers among Indian women. Analysis of trends would help in planning and organization of programs for control of these cancers. Objective: The objective of the following study is to compute risk of breast and cervical cancers using updated data from different cancer registries of India and study of its trends. Materials and Methods: Data on incidence rates of breast and cervical cancers were obtained from six major cancer registries of India for the years 1982-2008 and from the recently initiated cancer registries, North Eastern Registries of India with a total of 21 registries. Annual percent change in incidence and risk in terms of one in number of women likely to develop cancer was estimated for both the cancers in various registries. Results: The annual percentage change in incidence ranged from 0.46 to 2.56 and −1.14 to −3.4 for breast and cervical cancers respectively. Trends were significant for both cancers in the registries of Chennai, Bangalore, Mumbai and Delhi except Barshi and Bhopal. North East region showed decrease in risk for breast and cervical cancers whereas increasing trend was observed in Imphal (West and for cervical cancer in Silchar. Conclusion: North Eastern region recorded decline in the incidence of breast cancer which is contrary to the observation in other registries, which showed increase in breast cancer and decline in cervical cancer incidences.

  3. A New Method for Detection of Backscattered Signals from Breast Cancer Tumors: Hypothesis Testing Using an Adaptive Entropy-Based Decision Function

    Directory of Open Access Journals (Sweden)

    Seyed Vahab Shojaedini

    2012-03-01

    Full Text Available Introduction In recent years methods based on radio frequency waves have been used for detecting breast cancer. Using theses waves leads to better results in early detection of breast cancer comparing with conventional mammography which has been used during several years. Materials and Methods In this paper, a new method is introduced for detection of backscattered signals which are received by microwave breast radar. In this method, a decision function is constructed based on noise and signal cross-entropy, using hypothesis testing concept. Then noise and signal are separated using the calculated value for the decision function in each time frame. To estimate value of the decision function, discrete wavelet transform and discrete S transform are used. Results Performance of the proposed method was evaluated in two different scenarios, in which the breast was considered homogenous and heterogeneous, respectively. The obtained results showed that the proposed method detected breast backscattered signals 55% and 49% better than existing methods in two above scenarios. Conclusion Performance of S transform was 21% better than discrete wavelet transform in detection of weak backscattered signals. So it can be concluded that hypothesis testing method which uses S coefficients of received wave for construction of its decision function may be a suitable choice for detection of backscattered signals in breast radar.

    The relation between breast cancer and selected nonestrogenic drugs was evaluated in the Group Health Cooperative of Puget Sound, Seattle, Washington, a prepaid health care organization with computerized information on diagnoses and outpatient drug use. No important positive associations with breast cancer were found in a follow-up study of 302 women aged 35-74 years. These women were newly diagnosed with breast cancer in 1977-1980 and were studied in relation to exposure in the six months prior to diagnosis to one or more of the following drugs: diazepam, digitalis glycosides, medroxyprogesterone acetate, methyldopa, metronidazole, phenothiazines, tricyclic antidepressants, thiazides, thyroid/levothyroxine sodium, or spironolactone. A modest association between recent reserpine use and breast cancer was present (risk ratio = 1.7, 90% confidence interval 0.9-3.3).

    Full Text Available Abstract Background While some factors of breast morphology, such as density, are directly implicated in breast cancer, the relationship between breast size and cancer is less clear. Breast size is moderately heritable, yet the genetic variants leading to differences in breast size have not been identified. Methods To investigate the genetic factors underlying breast size, we conducted a genome-wide association study (GWAS of self-reported bra cup size, controlling for age, genetic ancestry, breast surgeries, pregnancy history and bra band size, in a cohort of 16,175 women of European ancestry. Results We identified seven single-nucleotide polymorphisms (SNPs significantly associated with breast size (p−8: rs7816345 near ZNF703, rs4849887 and (independently rs17625845 flanking INHBB, rs12173570 near ESR1, rs7089814 in ZNF365, rs12371778 near PTHLH, and rs62314947 near AREG. Two of these seven SNPs are in linkage disequilibrium (LD with SNPs associated with breast cancer (those near ESR1 and PTHLH, and a third (ZNF365 is near, but not in LD with, a breast cancer SNP. The other three loci (ZNF703, INHBB, and AREG have strong links to breast cancer, estrogen regulation, and breast development. Conclusions These results provide insight into the genetic factors underlying normal breast development and show that some of these factors are shared with breast cancer. While these results do not directly support any possible epidemiological relationships between breast size and cancer, this study may contribute to a better understanding of the subtle interactions between breast morphology and breast cancer risk.

    OBJECTIVE To observe trends in the changes of incidence and mortality of female breast cancer patients in Tianjin, and evaluate the effect of these trends on prevention. METHODS A method of descriptive epidemiology was used to comprehensively study the status of female breast cancer in Tianjin. RESULTS From 1981 to 2000, the incidence rate of breast cancer in Tianjin had been increasing at the speed of 1.8 % annually, whereas the peak of the age-adjusted incidence and mortality rate expressed a mild declining trend. Follow-up study indicated that 3 and 5-year survival rates improved in various degrees. CONCLUSION Early detection and diagnosis of breast cancer are very important to both increasing survival and lowering mortality from breast cancer. Preventive efforts should be promoted for women who are at high risk for breast cancer.

    Full Text Available Background. The incidence of premenopausal breast cancer is rising throughout South Asia. Our objective was to determine the role of risk factors associated with Westernization for premenopausal breast cancer in Bangladesh. Methods. We conducted a matched case-control study between January 1, 2007, and December 31, 2010, at four hospitals in Bangladesh. Cases were premenopausal women diagnosed with invasive breast cancer. Controls were premenopausal women with no personal history of breast cancer. Logistic regression was used to calculate the odds ratios (OR for breast cancer. Results. We identified 129 age-matched pairs. The mean age of breast cancer diagnosis was 37.5 years. Each year decrease in the age of menarche significantly increased the risk of breast cancer (OR = 1.67, 95% CI 1.09–2.56, P=0.02. The risk was also increased with a current body mass index of ≥25 kg/m2 (OR = 5.24, 95% CI 1.10–24.9, P=0.04. Age at first childbirth, parity, and breastfeeding were not significantly associated with premenopausal breast cancer risk (P>0.05. Conclusions. Age at menarche and adult weight gain were associated with premenopausal breast cancer risk. Other factors associated with Westernization may not be relevant to premenopausal breast cancer risk in Bangladesh.

    In this paper, we propose a method to identify abnormal growth of cells in breast tissue and suggest further pathological test, if necessary. We compare normal breast tissue with malignant invasive breast tissue by a series of image processing steps. Normal ductal epithelial cells and ductal / lobular invasive carcinogenic cells also consider for comparison here in this paper. In fact, features of cancerous breast tissue (invasive) are extracted and analyses with normal breast tissue. We also suggest the breast cancer recognition technique through image processing and prevention by controlling p53 gene mutation to some greater extent.

    Metalloestrogens are metals that activate the estrogen receptor in the absence of estradiol. The metalloestrogens fall into two subclasses: metal/metalloid anions and bivalent cationic metals. The metal/metalloid anions include compounds such as arsenite, nitrite, selenite, and vanadate while the bivalent cations include metals such as cadmium, calcium, cobalt, copper, nickel, chromium, lead, mercury, and tin. The best studied metalloestrogen is cadmium. It is a heavy metal and a prevalent environmental contaminant with no known physiological function. This review addresses our current understanding of the mechanism by which cadmium and the bivalent cationic metals activate estrogen receptor-α. The review also summarizes the in vitro and in vivo evidence that cadmium functions as an estrogen and the potential role of cadmium in breast cancer.

    2015-10-01

    Breast cancer is the second most common cancer worldwide and the leading cause of cancer death in women, with incidence rates that continue to rise. The heterogeneity of the disease makes breast cancer exceptionally difficult to treat, particularly for those patients with triple-negative disease. To address the therapeutic complexity of these tumours, new strategies for diagnosis and treatment are urgently required. The ability of lactating and malignant breast cells to uptake and transport iodide has led to the hypothesis that radioiodide therapy could be a potentially viable treatment for many breast cancer patients. Understanding how iodide is transported, and the factors regulating the expression and function of the proteins responsible for iodide transport, is critical for translating this hypothesis into reality. This review covers the three known iodide transporters - the sodium iodide symporter, pendrin and the sodium-coupled monocarboxylate transporter - and their role in iodide transport in breast cells, along with efforts to manipulate them to increase the potential for radioiodide therapy as a treatment for breast cancer.

    In many cases of human cancer, the appearance of hypersialylated glycan structures is related to a precise stage of the disease; this may depend on altered regulation of one or more sialyltransferases genes. Since several distinct sialyltransferase enzymes arising from different unique genes transfer sialic acid residues in the same linkage onto the same acceptor, it is impossible to precisely determine which enzyme is involved in the observed phenotype based on enzymatic assays. We have developed a very sensitive and highly reproducible multiplex reverse transcriptase-polymerase chain reaction technique in order to monitor the expression of four human sialyltransferases genes ST6Gal I, ST3Gal I, ST3Gal III and ST3Gal IV in small cell samples. Multiplex PCR amplification using specific primers for each sialyltransferase and detection of amplification products by polyacrylamide gel electrophoresis is a method that is fast and easy to handle and has proven to be useful for establishing sialyltransferase patterns of expression in breast immortalized cell line HBL100 as well as in breast cancer cell lines MCF-7/6, MCF-7/AZ and MDA.

Response assessment techniques derived from quantitative magnetic resonance imaging (MRI hold great potential for integration into treatment algorithms and clinical trials. Quantitative MRI techniques already available for assessing breast cancer response to neoadjuvant therapy include lesion size measurement, dynamic contrast-enhanced MRI, diffusion-weighted MRI, and proton magnetic resonance spectroscopy. Emerging yet promising techniques include magnetization transfer MRI, chemical exchange saturation transfer MRI, magnetic resonance elastography, and hyperpolarized MR. Translating and incorporating these techniques into the clinical setting will require close attention to statistical validation methods, standardization and reproducibility of technique, and scanning protocol design.Keywords: treatment response, presurgical treatment, neoadjuvant chemotherapy

    Full Text Available Many of breast-cancer patients experience distress and most of them experience depression which may lead to amplification of physical symptoms, increased functional impairment, and poor treatment adherence. We did a review on available literature from PubMed about prevalence, distress magnitudes, coping styles, and treatment methods of major depression in women with breast cancer from 1978 to 2010. Diagnosis and treatment of depressive episodes in women with breast cancer is challenging because of overlapping symptoms and co-morbid conditions. Major depression is often under-recognized and undertreated among breast cancer patients. This review highlighted the issues on identifying and managing depression in breast cancer patients in clinical settings.

Tumor classification is determined in primary tumor tissue and metastatic biopsies. However, malignant cells tend to alter their phenotype during disease progression. Circulating tumor cell (CTC analysis may serve as an alternative to repeated biopsies. The Food and Drug Administration-approved CellSearch system allows determination of the HER-2 protein, but not of the HER-2 gene. The aim of this study was to optimize a fluorescence in situ hybridization (FISH-based method to quantitatively determine HER-2 amplification in breast cancer CTCs following CellSearch-based isolation and verify the method in patient samples. Methods: Using healthy donor blood spiked with human epidermal growth factor receptor 2 (HER-2-positive breast cancer cell lines, SKBr-3 and BT-474, and a corresponding negative control (the HER-2-negative MCF-7 cell line, an in vitro CTC model system was designed. Following isolation in the CellSearch system, CTC samples were further enriched and fixed on microscope slides. Immunocytochemical staining with cytokeratin and 4',6-diamidino-2'-phenylindole dihydrochloride identified CTCs under a fluorescence microscope. A FISH-based procedure was optimized by applying the HER2 IQFISH pharmDx assay for assessment of HER-2 amplification status in breast cancer CTCs. Results: A method for defining the presence of HER-2 amplification in single breast cancer CTCs after CellSearch isolation was established using cell lines as positive and negative controls. The method was validated in blood from breast cancer patients

    Full Text Available Introduction: Contralateral breast cancer can be synchronous and/or metachronous in patients with cancer of one breast. Detection of a synchronous breast cancer may affect patient management. Dynamic contrast-enhanced MRI of the breast (DCE-MRI is a sensitive technique for detecting contralateral lesions occult on the other imaging modalities in women already diagnosed with cancer of one breast. Aim: The aim was to assess the incidence of mammographically occult synchronous contralateral breast cancer in patients undergoing MRI mammography for the evaluation of a malignant breast lesion. Materials and Methods: A total of 294 patients with recently diagnosed breast cancer who underwent MRI of the breast were evaluated for lesions in the opposite breast. Results: The incidence of synchronous contralateral malignancy detected by preoperative MRI mammography done for evaluation of extent of disease was 4.1%. Conclusion: Preoperative breast MRI may detect clinically and mammographically occult synchronous contralateral cancer, and can help the patient avoid an additional second surgery or a second course of chemotherapy later; also, as theoretically these lesions are smaller, there may be a survival benefit as well.

    Breast cancer is defined as a chronic disease.Increasing amounts of attention have been paid to the health management of breast cancer survivors. An important issue is how to find the most appropriate method of follow-up in order to detect long-term complications of treatment, local recurrence and distant metastasis and to administer appropriate treatment to the survivors with recurrence in a timely fashion. Different oncology organizations have published guidelines for following up breast cancer survivors. However, there are few articles on this issue in China. Using the published follow-up guidelines,we analyzed their main limitations and discussed the content,follow-up interval and economic benefits of following up breast cancer survivors in an effort to provide suggestions to physicians.Based on a large number of clinical trials, we discussed the role of physical examination, mammography, liver echograph, chest radiography, bone scan and so on. We evaluated the effects of the above factors on detection of distant disease, survival time,improvement in quality of life and time to diagnosis of recurrence.The results of follow-up carried out by oncologists and primary health care physicians were compared. We also analyzed the correlation factors for the cost of such follow-up. It appears that follow-up for breast cancer survivors can be carried out effectively by trained primary health care physicians. If anything unusual arises, the patients should be transferred to specialists.

    Breast cancer is the most common cancer in women, and the second most common cause of cancer death after lung cancer. Improvements in the outcome of breast cancer mean that more patients are living longer and are, therefore, at risk of developing a second malignancy. The aim of this review is to present the current understanding of the risk of lung cancer arising in patients previously treated for early stage breast cancer. We review data on the effect of treatment factors (ie, surgery type, radiotherapy technique, and adjuvant chemotherapy) and patient factors (ie, age and smoking) on the risk of developing a subsequent lung cancer. The evidence suggests that older radiotherapy techniques were associated with a substantially increased risk of developing lung cancer in the ipsilateral lung, but there is no clear evidence of an increased risk with modern techniques. Smoking is an important risk factor, and increases the risk of lung cancer in those receiving radiotherapy. Adjuvant chemotherapy is not significantly associated with an increased risk. The risk of developing lung cancer increases with time elapsed since treatment, but any effect of age at treatment is unclear.

    In this article we draw on Bury's theory of biographical disruption to discuss the meanings of, and emotional experiences related to, being diagnosed with breast cancer among southern Thai women. Qualitative methods, including in-depth interviewing and drawing methods, were used to collect data from 20 women with breast cancer. The women perceived breast cancer to be a rhok raai; an evil or dread disease. They believed that breast cancer would lead to death. The disruption in their biography occurred when they detected abnormalities indicating breast cancer. The women's narratives revealed their chaotic lives upon this diagnosis and the news precipitated in them shock, fear, anxiety and loss of hope. Although they experienced chaos and disruption, the women cultivated strategies that helped them cope with their experiences by accepting their fate and adhering to Buddhist beliefs and practices. Through their narratives of biographical disruption, the women in our study offer healthcare providers knowledge that could lead to an appreciation of their needs and concerns. This knowledge is crucial for health professionals who wish to provide emotional support to women who have been diagnosed with breast cancer in Thailand and elsewhere.

    Full Text Available Erica Jackson, Hatem SolimanUniversity of South Florida/Moffitt Cancer Center and Research Institute, Tampa, FL, USAAbstract: Breast cancer vaccines are being developed to stimulate adaptive antitumor immune responses in patients. These vaccines have the potential to treat breast cancer with minimal side effects and toxicity. However, many obstacles still need to be overcome to fully realize the vaccines' clinical benefit. A review of the literature was conducted to assess the use of vaccines in targeting transformed cells. Four vaccines currently under study were discussed, each summarizing the different vaccine platforms used to introduce target antigen to the patient's immune system. The advantages and disadvantages of each method were discussed, although no one method was found to be superior. Additional issues addressed included overcoming tumor-induced immunosuppression, immune evasion of transformed cells, the use of vaccines in combination therapy, and the challenges of using these vaccines in various clinical settings. Vaccines may be most effective in patients with minimal residual disease, as opposed to using them in the metastatic setting. Also, specific clinical trial design considerations for the use of vaccines in cancer patients, such as time-to-failure end points, were discussed. Understanding these various elements will be important to the translation of breast cancer vaccine therapy into routine clinical practice.Keywords: breast cancer, vaccine, immunotherapy, immune tolerance, peptide vaccine, dendritic cell vaccine

    Advances in female breast imaging have substantially influenced the diagnosis, therapy, and prognosis of breast cancer in the past few years. Mammography using conventional or digital technique is considered the gold standard for the early detection of breast cancer. Other modalities such as breast ultrasound and contrast-enhanced magnetic resonance imaging of the breast play an important role in diagnostic imaging, staging, and follow-up of breast cancer. Percutaneous needle biopsy is a faster, less invasive, and more cost-effective method than surgical biopsy for verifying the histological diagnosis. New methods such as breast tomosynthesis, contrast-enhanced mammography, and positron emission tomography promise to further improve breast imaging. Further studies are mandatory to adapt these new methods to clinical needs and to evaluate their performance in clinical practice. (orig.) [German] Die Fortschritte bei den bildgebenden Verfahren der weiblichen Brust haben in den letzten Jahren die Diagnostik, die Therapie und die Prognose des Mammakarzinoms erheblich beeinflusst.

    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.

    Determination of salivary cortisol using radioimmunoassay and the relationship between stress levels were investigated before and after of the psychological intervention of 21 patients during teletherapy treatment of breast cancer. The benefits of psychological intervention during cancer treatment has been observed in some studies and evidence show that the patient's emotional state directly influences adherence to treatment, good prognosis and under stress. Thus, in present study 21 patients aged 50-70 years, females in the treatment of breast cancer at the Radiotherapy Service of Santa Casa de Misericordia in Belo Horizonte, were divided randomly into two groups: control (without psychological intervention) and Group TCC (with psychological intervention). Salivary cortisol concentrations are reportedly about 5.10% of those in serum, the levels has been used as an objective marker of hypothalamic-pituitary-adrenal (HPA) axis activity and avoided the confounding effects of venepuncture stress on cortisol levels. The assessment of cortisol in saliva has proven a valid and reliable measure of unbound steroid in the circulation. The salivary cortisol measured by radioimmunoassay in control patients and TCC showed no significant differences. The radioimmunoassay method show be suitable for analysis of salivary cortisol because allows measure low detection limits and have high sensibility. The values of TCC group and Control group were higher than reference values, except for one patient of the control group. At the beginning of treatment, both groups were homogeneous for Teletherapy. Both the TCC group as the control group had . 80% of participants in phase with stress. It was observed in the TCC group after radiotherapy showing a reversal 60% of participants without stress. The data show that cognitive-behavioral therapy has benefits for the control of psychological stress and enhance relevance of the psychologist to provide reduction or stress control during

    Nowadays, HER2 testing in breast cancer represents a necessity for both prognostic and therapy. Despite widespread use of immunohistochemistry (IHC) for assessing HER2 status, there are some limitations to identify truly negative or positive HER2 cases. Fluorescence in situ hybridization (FISH) or chromogenic in situ hybridization (CISH) could solve the equivocal HER2 IHC cases but there is no consensus on which is the best method. Consequently, finding a sensitive method for HER2 testing is critical for the management of the disease. In addition, tumor heterogeneity is an important factor which could affect accuracy of molecular diagnostics. Laser capture micro-dissection (LCM) is used to isolate pure cell populations from heterogeneous tumor tissue. The combination between LCM and quantitative polymerase chain reaction (Q-PCR), the gold standard in molecular biology for quantifying gene amplification levels, could define an important tool to improve the molecular diagnostics of HER2 status.In our pilot study we used LCM and Q-PCR to evaluate HER2 gene amplification for invasive breast carcinoma samples. The samples were selected based on HER2 status assessed by IHC and CISH. Our results demonstrated high sensitivity of Q-PCR for assessing HER2 DNA amplification as well as a good concordance between Q-PCR and IHC/ CISH assay.

    Hierarchical clustering algorithms, such as Pearson's correlation, Euclidean distance, Euclidean distance harmonic,Spearman rank correlation, Kendall's tau, and City-block distance, were used to find the best way to establish theoretical MAPK/Erk signaling pathway on the basis of breast cancer line MCF-7 gene expressions. The algorithm consttucts a hierarchy from top to bottom on the basis of a self-organizing tree. It dynamically finds the number of clusters at each level. It was found that only Euclidean distance harmonic is fit for the analysis of the cascade composed from a RAF1 (c-Raf), a MKNK1, a MAPKK (MEK1/2) to MAPK (Erk) in breast cancer line MCF-7. The result is consistent with the biological experimental MAP/Erk signaling pathway, and the theoretical MAPK/Erk signaling pathway on breast cancer line MCF-7 is set up.

    This research examined media coverage of breast cancer (n = 145) and heart disease and stroke (n = 39) news articles, videos, advertisements, and images in a local Canadian context through quantitative and thematic content analyses. Quantitative analysis revealed significant differences between coverage of the diseases in placement, survivors as a source of information, health agency, human interest stories, citation of a research study, the inclusion of risk statistics, discussion of preventative behaviors, and tone used. The thematic analysis revealed themes that characterized a "typical" breast cancer survivor and indicated that "good" citizens and businesses should help the cause of breast cancer. Themes for heart disease and stroke articulated individual responsibility and the ways fundraising reinforced femininity and privilege. Findings provide insight on how these diseases are framed in local Canadian media, which might impact an individual's understanding of the disease.

    Full Text Available Abstract Background Elevated pregnancy estrogen levels are associated with increased risk of developing breast cancer in mothers. We studied whether pregnancy weight gain that has been linked to high circulating estrogen levels, affects a mother's breast cancer risk. Methods Our cohort consisted of women who were pregnant between 1954–1963 in Helsinki, Finland, 2,089 of which were eligible for the study. Pregnancy data were collected from patient records of maternity centers. 123 subsequent breast cancer cases were identified through a record linkage to the Finnish Cancer Registry, and the mean age at diagnosis was 56 years (range 35 – 74. A sample of 979 women (123 cases, 856 controls from the cohort was linked to the Hospital Inpatient Registry to obtain information on the women's stay in hospitals. Results Mothers in the upper tertile of pregnancy weight gain (>15 kg had a 1.62-fold (95% CI 1.03–2.53 higher breast cancer risk than mothers who gained the recommended amount (the middle tertile, mean: 12.9 kg, range 11–15 kg, after adjusting for mother's age at menarche, age at first birth, age at index pregnancy, parity at the index birth, and body mass index (BMI before the index pregnancy. In a separate nested case-control study (n = 65 cases and 431 controls, adjustment for BMI at the time of breast cancer diagnosis did not modify the findings. Conclusions Our study suggests that high pregnancy weight gain increases later breast cancer risk, independently from body weight at the time of diagnosis.

    To evaluate the mammographic and clinical findings of nonpalpable breast cancer. Materials and Methods : In 28 of 607 breast cancer patients examined between January 1994 and April 1997, lesions were nonpalpable. We retrospectively analyzed the mammographic, clinical and pathologic features of 25 patients (28 lesions) whose mammograms we obtained. Results : Among these 25 patients (28 lesions) screening was abnormal in 22; other symptoms were bloody nipple discharge(n=4), and nipple eczema(n=2). The patients were 34-62 (mean 52)years old. Invasive ductal carcinoma(n=13), DCIS(ductal carcinoma in situ, n-12), Paget's disease (n=2), and LCIS(lobular carcinoma in situ, n=1) were found during surgery. Six of 28 lesions(21%) showed evidence of axillary nodal metastasis;the majority arose from the upper outer quadrant of the breast (n=21). The mammographic findings were mass (50%), (and mass with microcalcification, 11%); microcalcification(29%); asymmetrical density(14%); and normal (7%). According to the mammographic density of breast parenchyma, the major finding in the low density group(N1+P1) was mass(9/9), and in the high density group(P2+DY) was microcalcification (12/19). Conclusion : The most common mammographic findings of nonpalpable breast cancer were mass (50%) and microcalcification(29%). Its features varied according to the mammographic density of breast parenchyma;mass was the main finding in the low density group and microcalcification in the high density group.

    In the United States, one in eight women will be affected by breast cancer. According to the American Cancer Society, breast cancer is the most commonly diagnosed - as well as the second most fatal - cancer in American women. It is estimated that there will be nearly 200,000 diagnoses of breast cancer this year; more than 40,000 of these will be fatal. Although advances in medical technologies have greatly increased the odds of surviving the disease, the increase in screenings has not resulted in a significant reduction in the breast cancer mortality rate. Moreover, recent studies have even suggested that an increase in these methods might, in itself, cause cancer. A new tool for early detection and diagnosis of breast cancer, supported by an award from the Breast Cancer Research Program (BCRP) of the Congressionally Directed Medical Research Programs of Department of Defense, could give women a new advantage in the fight against breast cancer. This LANL-led project will integrate ultrasound tomography (UST) with recent discoveries in the field of cell and tissue biomechanics to improve breast cancer detection and characterization. UST uses ultrasound waves instead of X-rays to identify and characterize breast tumors. This technology reveals small mechanical-property changes within the breast. These changes are often the earliest signs of breast cancer. Additionally, UST is effective for women with dense breast tissue, who have a higher risk of developing breast cancer. Because the technology does not use radiation, UST can also be used as frequently as needed for women with a high risk of developing breast cancer. In contrast, mammography, the only routine breast-cancer screening tool currently available, is not effective for women with dense breast tissue and may come with unwanted side-effects caused by ionizing radiation. UST has great potential to become an alternative breast-cancer screening tool because of UST's advantages and benefits over mammography

    Secretory carcinoma of the breast is a rare tumor initially described in children but occurring equally in adult population. This unusual breast cancer subtype has a generally favorable prognosis, although several cases have been described in adults with increased aggressiveness and a risk of metastases. However, surgery is still considered the most appropriate treatment for this pathology. We describe the case of a 50 -year-old woman who has undergone a breast conservative surgery for a little tumor, preoperatively diagnosticated by a fine needle aspiration biopsy (FNAB) as a well differentiated infiltrating carcinoma.

    Full Text Available Abstract Background Young breast cancer patients have a lower rate of survival than old breast cancer patients due to being diagnosed at advanced stages. Breast self-examination makes women more "breast aware", which in turn may lead to an earlier diagnosis of breast cancer. The purpose of this study was to investigate knowledge and practice of breast self-examination and to determine knowledge of risk factors for breast cancer among high school students. Methods This is a descriptive and cross-sectional study. It was conducted in a high school in Manisa, Turkey. The study sample included 718 female high school students. A socio-demographic characteristics data form, knowledge of breast self examination and risk factors for breast cancer form and breast self examination practice form were used to collect data. Results The female high school students had insufficient knowledge about breast self-examination and a low percentage of students reported that they had performed breast self examination monthly. The most common reason for not doing breast self- examination was "not knowing how to perform breast self-examination" (98.5%. Most of the students had little knowledge of the risk factors for breast cancer. The most widely known risk factor by the students was personal history of breast cancer (68.7%. There was a significant relation between breast self-examination practice and age, school grade, knowledge about breast cancer and knowledge about breast self- examination. Conclusion There is a need to increase knowledge of adolescent females about the risks of breast cancer and benefits of early detection. In fact, health care professionals can develop effective breast health care programs and help young women to acquire good health habits.

    Introduction: Intracystic (encysted) papillary cancer (IPC) is a rare entity of breast cancer accounting for approximately (1–2%) of all breast tumours [1], usually presenting in postmenopausal women and having an elusive natural history. The prediction of the biological behaviour of this rare form of breast cancer and the clinical outcome showed its overall favourable prognosis; however, its consideration as a form of ductal carcinoma in situ with non-invasive nature is to be reconsidered as it has been shown to present histologically with invasion of basement membrane and even metastasis [2]. The objective of this review is to shed some light on this rare, diagnostically challenging form of breast cancer, including its radiological, histological, and molecular characteristics and its pathological classification. The final goal is to optimize the clinical management including the role of sentinel lymph node biopsy (SLNB), general management with adjuvant radiotherapy (RT), mammary ductoscopy, and hormonal treatment. Methods: A literature review, facilitated by Medline, PubMed, and the Cochrane database, was carried out using the terms ‘Intracystic (encysted) papillary breast cancer’. Results: Intracystic papillary breast cancer (IPC) is best managed in the context of a multidisciplinary team. Surgical excision of the lump with margins in excess of 2 mm is considered satisfactory. Sentinel lymph node biopsy (SLNB) is recommended as data have shown the possibility of the presence of invasive cancer in the final histology. RT following IPC alone is of uncertain significance as this form of cancer is usually low grade and rarely recurs. However, if it is associated with DCIS or invasive cancer and found in young women, radiotherapy may be prudent to reduce local recurrence. Large tumours, centrally located or in cases where breast conserving surgery is unable to achieve a favourable aesthetic result, a skin sparing mastectomy with the opportunity for immediate

    Full Text Available Abstract Introduction Clustered within the nomenclature of Asian American are numerous subgroups, each with their own ethnic heritage, cultural, and linguistic characteristics. An understanding of the prevailing health knowledge, attitudes, and screening behaviors of these subgroups is essential for creating population-specific health promotion programs. Methods Korean American women (123 completed baseline surveys of breast cancer knowledge, attitudes, and screening behaviors as part of an Asian grocery store-based breast cancer education program evaluation. Follow-up telephone surveys, initiated two weeks later, were completed by 93 women. Results Low adherence to the American Cancer Society's breast cancer screening guidelines and insufficient breast cancer knowledge were reported. Participants' receptiveness to the grocery store-based breast cancer education program underscores the importance of finding ways to reach Korean women with breast cancer early detection information and repeated cues for screening. The data also suggest that the Asian grocery store-based cancer education program being tested may have been effective in motivating a proportion of the women to schedule a breast cancer screening between the baseline and follow-up surveys. Conclusion The program offers a viable strategy to reach Korean women that addresses the language, cultural, transportation, and time barriers they face in accessing breast cancer early detection information.

    The biological concept of bilateral symmetry as a marker of developmental stability and good health is well established. Although most individuals deviate slightly from perfect symmetry, humans are essentially considered bilaterally symmetrical. Consequently, increased fluctuating asymmetry of paired structures could be an indicator of disease. There are several published studies linking bilateral breast size asymmetry with increased breast cancer risk. These studies were based on radiologists' manual measurements of breast size from mammographic images. We aim to develop a computerized technique to assess fluctuating breast volume asymmetry in screening mammograms and investigate whether it correlates with the presence of breast cancer. Using a large database of screening mammograms with known ground truth we applied automated breast region segmentation and automated breast size measurements in CC and MLO views using three well established methods. All three methods confirmed that indeed patients with breast cancer have statistically significantly higher fluctuating asymmetry of their breast volumes. However, statistically significant difference between patients with cancer and benign lesions was observed only for the MLO views. The study suggests that automated assessment of global bilateral asymmetry could serve as a breast cancer risk biomarker for women undergoing mammographic screening. Such biomarker could be used to alert radiologists or computer-assisted detection (CAD) systems to exercise increased vigilance if higher than normal cancer risk is suspected.

    Inflammatory breast cancer (IBC) is the most aggressive entity of breast cancer. Management involves coordination of multidisciplinary management and usually includes neoadjuvant chemotherapy, ablative surgery if a tumor-free resection margin is expected and locoregional radiotherapy. This multimodal therapeutic approach has significantly improved patient survival. However, the median overall survival among women with IBC is still poor. By elucidating the biologic characteristics of IBC, new treatment options may become available. We performed a comprehensive review of the English-language literature on IBC through computerized literature searches. The objective of the current review is to present an overview of the literature related to the biology, imaging and multidisciplinary treatment of inflammatory breast cancer.

    Breast cancer is a disease many will experience. Depending on the size of the cancer, the size of the host breast, and whether it is multi-focal, a mastectomy may be recommended as part of the treatment. If this is the case, an immediate breast reconstruction may be offered. This article will describe the three main types of breast reconstruction and discuss pertinent issues regarding this, including complications, surgery to the other (contraleteral) breast and potential psychological implications of this surgery.

    Breast cancer is a multifactorial disease and the most commonly diagnosed cancer in women. Traditional risk factors for breast cancer include reproductive status, genetic mutations, family history and lifestyle. However, increasing evidence has identified an association between breast cancer and occupational factors, including environmental stimuli. Epidemiological and experimental studies demonstrated that ionizing and non-ionizing radiation exposure, night-shift work, pesticides, polycyclic aromatic hydrocarbons and metals are defined environmental factors for breast cancer, particularly at young ages. However, the mechanisms by which occupational factors can promote breast cancer initiation and progression remains to be elucidated. Furthermore, the evaluation of occupational factors for breast cancer, particularly in the workplace, also remains to be explained. The present review summarizes the occupational risk factors and the associated mechanisms involved in breast cancer development, in order to highlight new environmental exposures that could be correlated to breast cancer and to provide new insights for breast cancer prevention in the occupational settings. Furthermore, this review suggests that there is a requirement to include, through multidisciplinary approaches, different occupational exposure risks among those associated with breast cancer development. Finally, the design of new epigenetic biomarkers may be useful to identify the workers that are more susceptible to develop breast cancer.

    Full Text Available Inflammatory breast cancer is one of the most aggressive forms of breast cancer. Once considered to be a uniformly fatal disease, treatment of this entity has evolved significantly over the last two decades. In this article, we review the epidemiology, pathology, biologic underpinnings, radiologic advances, and treatment modalities for inflammatory breast cancer. Updates in surgical therapy, medical oncologic therapy and radiation therapy are reviewed. Emphasis is on cutting edge information regarding inflammatory breast cancer. The management of inflammatory breast cancer is best served by a multidisciplinary team. Continued research into molecular pathways and potential targets is imperative. Future clinical trials should include evaluation of conventional therapy with targeted therapies.

    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 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

    Background: Adipokines and inflammation may provide a mechanistic link between obesity and postmenopausal breast cancer, yet epidemiologic data on their associations with breast cancer risk are limited. Methods: In a case-cohort analysis nested within the Women’s Health Initiative Observational Study, a prospective cohort of postmenopausal women, baseline plasma samples from 875 incident breast cancer case patients and 839 subcohort participants were tested for levels of seven adipokines, namely leptin, adiponectin, resistin, interleukin-6, tumor necrosis factor-α, hepatocyte growth factor, and plasminogen activator inhibitor-1, and for C-reactive protein (CRP), an inflammatory marker. Data were analyzed by multivariable Cox modeling that included established breast cancer risk factors and previously measured estradiol and insulin levels. All statistical tests were two-sided. Results: The association between plasma CRP levels and breast cancer risk was dependent on hormone therapy (HT) use at baseline (P interaction = .003). In a model that controlled for multiple breast cancer risk factors including body mass index (BMI), estradiol, and insulin, CRP level was positively associated with breast cancer risk among HT nonusers (hazard ratio for high vs low CRP levels = 1.67, 95% confidence interval = 1.04 to 2.68, P trend = .029). None of the other adipokines were statistically significantly associated with breast cancer risk. Following inclusion of CRP, insulin, and estradiol in a multivariable model, the association of BMI with breast cancer was attenuated by 115%. Conclusion: These data indicate that CRP is a risk factor for postmenopausal breast cancer among HT nonusers. Inflammatory mediators, together with insulin and estrogen, may play a role in the obesity–breast cancer relation. PMID:26185195

    Plasma DNA integrity index is increased in various malignancies including breast cancer, the most common cancer in women worldwide; early detection is crucial for successful treatment. Current screening methods fail to detect many cases of breast cancer at an early stage. In this study, we evaluated the level of plasma DNA integrity index in 260 females (95 with breast cancer, 95 with benign breast lesions, and 70 healthy controls) to verify its potential value in discriminating malignant from benign breast lesions. The criteria of the American Joint Committee on Cancer were used for staging of breast cancer patients. DNA integrity index was measured by real-time PCR. DNA integrity index was significantly higher in breast cancer than in benign breast patients and healthy subjects (P = cancer group was 85.3 % at 0.55 DNA integrity index cutoff. In conclusion, the plasma DNA integrity index may be a promising molecular diagnostic marker of malignancy in breast lesions.

    Full Text Available Second to the cardiovascular disease, cancer is the main cause of death in Iran. In this study some of the risk factors of breast cancer; especially the ones related to breastfeeding have been assessed. The study was a retrospective study of 100 women with breast cancer. The most important risk factors in breast cancer were number of children, age of mother on the first pregnancy. The result showed that the increase of breast cancer was related to women who stopped breastfeeding before age 24 months. Breastfeeding for more than 12 months will reduce the incidence of breast cancer by 25%. In general there was a reverse relationship between duration of breastfeeding and risk of cancer in premonopausal, but not in postmenopausal women.

    1999-01-01

    The Fiber Hypothesis which had its origins in the work of Burkitt and others in the early 1970's, focussed largely on fiber's beneficial effects on colon cancer and disorders of the gastric intestinal tract. In the 1980's it was proposed that fiber may also have beneficial effects on breast cancer and a rational for this was proposed involving modulation, by fiber, of the enterohepatic recirculation of estrogens. In the following the evidence from epidemiology, clinical interventions and animal model studies, supporting a role for fiber in breast cancer is critically reviewed. Evidence from animal model studies support the notion that supplementary fiber inhibits chemically-induced mammary tumorigenesis but do not support an estrogen-based mechanism. Some studies in human populations suggest modulation by estrogens and some do not. The aggregate data point to minor constituents present in fiber, such as isoflavones and phytate as the biologically active components of fiber which may be responsible for its anti cancer effects.

  7. HIV tropism and decreased risk of breast cancer.

    Directory of Open Access Journals (Sweden)

    Nancy A Hessol

    Full Text Available BACKGROUND: During the first two decades of the U.S. AIDS epidemic, and unlike some malignancies, breast cancer risk was significantly lower for women with human immunodeficiency virus (HIV infection compared to the general population. This deficit in HIV-associated breast cancer could not be attributed to differences in survival, immune deficiency, childbearing or other breast cancer risk factors. HIV infects mononuclear immune cells by binding to the CD4 molecule and to CCR5 or CXCR4 chemokine coreceptors. Neoplastic breast cells commonly express CXCR4 but not CCR5. In vitro, binding HIV envelope protein to CXCR4 has been shown to induce apoptosis of neoplastic breast cells. Based on these observations, we hypothesized that breast cancer risk would be lower among women with CXCR4-tropic HIV infection. METHODS AND FINDINGS: We conducted a breast cancer nested case-control study among women who participated in the WIHS and HERS HIV cohort studies with longitudinally collected risk factor data and plasma. Cases were HIV-infected women (mean age 46 years who had stored plasma collected within 24 months of breast cancer diagnosis and an HIV viral load≥500 copies/mL. Three HIV-infected control women, without breast cancer, were matched to each case based on age and plasma collection date. CXCR4-tropism was determined by a phenotypic tropism assay. Odds ratios (OR and 95% confidence intervals (CI for breast cancer were estimated by exact conditional logistic regression. Two (9% of 23 breast cancer cases had CXCR4-tropic HIV, compared to 19 (28% of 69 matched controls. Breast cancer risk was significantly and independently reduced with CXCR4 tropism (adjusted odds ratio, 0.10, 95% CI 0.002-0.84 and with menopause (adjusted odds ratio, 0.08, 95% CI 0.001-0.83. Adjustment for CD4+ cell count, HIV viral load, and use of antiretroviral therapy did not attenuate the association between infection with CXCR4-tropic HIV and breast cancer. CONCLUSIONS: Low

    Full Text Available Background. Evidence is accumulating that circulating tumor cells (CTC out of peripheral blood can serve as prognostic marker not only in metastatic but also in early breast cancer (BC. Various methods are available to detect CTC. Comparisons between the different techniques, however, are rare. Material and Methods. We evaluate two different methods for CTC enrichment and detection in primary BC patients: the FDA-approved CellSearch System (CSS; Veridex, Warren, USA and a manual immunocytochemistry (MICC. The cut-off value for positivity was ≥1 CTC. Results. The two different nonoverlapping patient cohorts evaluated with one or the other method were well balanced regarding common clinical parameters. Before adjuvant CHT 21.1% (416 out of 1972 and 20.6% (247 out of 1198 of the patients were CTC-positive, while after CHT 22.5% (359 out of 1598 and 16.6% (177 out of 1066 of the patients were CTC-positive using CSS or MICC, respectively. CTC positivity rate before CHT was thus similar and not significantly different (P=0.749, while CTC positivity rate immediately after CHT was significantly lower using MICC compared to CSS (P<0.001. Conclusion. Using CSS or MICC for CTC detection, we found comparable prevalence of CTC before but not after adjuvant CHT.

    Objective: Mammography has been established as the gold standard for the detection of breast cancer, and imaging techniques such as ultrasonography, magnetic resonance imaging, scintigraphy and positron emission tomography may be useful to improve its sensitivity and specificity. The objective of this study with breast scintigraphy was to evaluate the uptake of {sup 99m}Tc-thymine in mammary lesions. Methods: A total of 45 patients were included in this study. Thirty-three patients (73%) were subjected to surgery or percutaneous biopsy, providing histopathological data. The other 12 patients who remained under surveillance received clinical examinations and biannual mammography with a normal follow-up of at least three years, the data from which were used for comparison with the scintimammography results. Results: The majority of patients (64.4%) had clinically impalpable lesions with a mammogram diagnosis of microcalcifications, impalpable nodules, or focal asymmetry. Of the studied lesions, 87% were smaller or equal to 20 mm in diameter, and 22% had malignant histopathological findings. Scintigraphy with {sup 99m}Tc-thymine had a sensitivity of 70%, a specificity of 85.7%, positive and negative predictive values of 58.3% and 90.9%, respectively, and an accuracy of 82.2%. Conclusions: The results of this study are consistent with those previously reported by other authors. The good specificity and high negative predictive value of this technique and the absence of uptake in the heart indicate that it may be a promising complementary method in clinical practice and that it may contribute to reducing unnecessary benign biopsies.

    Full Text Available Surgery and irradiation for breast cancer may interfere with conventional pathways of spread, leading to bizarre patterns of dissemination through lymphatics or through hematogenous route. Lymphoscintigraphic studies may help identify nodal involvement. Other possible reasons could be occurrence of primary breast cancer in accessory breast tissue retained in the vulva following involution of milk line. We describe a case of triple negative breast cancer, who developed contralateral breast cancer during treatment. Three years later, she developed isolated inguinal nodal metastases, which responded to local radiotherapy and chemotherapy. However, the patient relapsed after 2 years and could not be salvaged thereafter.

    An early diagnostic biomarker for breast cancer is essential to improve outcome. High precision isotopic analysis, originating in Earth sciences, can detect very small shifts in metal pathways. For the first time, the natural intrinsic Zn isotopic compositions of various tissues in breast cancer patients and controls were determined. Breast cancer tumours were found to have a significantly lighter Zn isotopic composition than the blood, serum and healthy breast tissue in both groups. The Zn isotopic lightness in tumours suggests that sulphur rich metallothionein dominates the isotopic selectivity of a breast tissue cell, rather than Zn-specific proteins. This reveals a possible mechanism of Zn delivery to Zn-sequestering vesicles by metallothionein, and is supported by a similar signature observed in the copper isotopic compositions of one breast cancer patient. This change in intrinsic isotopic compositions due to cancer has the potential to provide a novel early biomarker for breast cancer.

    2013-01-01

    BACKGROUND Despite current recommendations for women to be screened for breast cancer with mammography every one to two years, less than half of all newly diagnosed breast cancers are initially detected through screening mammography. Prompt medical attention to a new breast symptom can result in earlier stage at diagnosis, yet many patients delay seeking medical care after becoming aware of a breast symptom. METHODS In a population-based study of breast cancer we examined factors potentially associated with patient delay in seeking health care for a breast symptom among 436 symptomatic urban breast cancer patients (146 White, 197 Black and 95 Hispanic). Race/ethnicity, socioeconomic status, health care access and utilization, and misconceptions about the meaning of breast lumps were the key independent variables. RESULTS Sixteen percent of patients reported delaying more than 3 months before seeking medical advice about breast symptoms. Misconceptions about breast lumps, and lacking a regular provider, health insurance and recent preventive care were all associated with prolonged patient delay (p<0.005 for all). Misconceptions were much more common among ethnic minorities and women of lower socioeconomic status. CONCLUSION Reducing patient delay and disparities in delay will require both educating women about the importance of getting breast lumps evaluated in a timely manner, and providing greater access to regular health care.

    2016-01-01

    Breast cancer affected 1.7 million people worldwide in 2012 and accounts for approximately 23.3% of all cancers diagnosed in women. The disease is characterized by a genetic mutation, either inherited or resulting from envi-ronmental factors, that causes uncontrollable cellular growth of breast tissue or adjacent tissues. Current means of diag-nosing this disease depend on the individual analyzing the results from bulky, highly technical, and expensive equipment that is not globally accessible. As a result, patients can go undiagnosed due to a lack of available equipment or be over-diagnosed due to human error. This review attempts to highlight current means of diagnosing breast cancer and critically analyze their effectiveness and usefulness in terms of patient survival. An alternative means based on microfluidics biomarker detection is then presented. This method can be considered as a primary screening tool for diagnosing breast cancer based on its robustness, high throughput, low energy requirements, and accessibility to the general public.

    OBJECTIVE: To assess the knowledge of nurses involved in the care of oncology patients in a public university hospital, regarding breast cancer and hereditary breast cancer, and to verify the use of such knowledge in their daily practice. METHODS: This is a descriptive cross-sectional study. Data were obtained through a structured, self-administered questionnaire. Out of 154 nurses, 137 (88.9%) agreed to participate in the study. Two questionnaires were excluded such that 135 questionnaires were analyzed. RESULTS: The global percentage of correct answers was not associated with age (p=0.173) or degree/specialization (p=0.815). Questions were classified into categories. In categories involving knowledge of established breast cancer risk factors and indicators of hereditary breast cancer, the rate of correct answers was 65.8% and 66.4%, respectively. On the practice of genetic counseling, 40.7% of those interviewed were not sure about the definition of genetic counseling and 78.5% reported never having identified or referred a patient at genetic risk for specialized risk assessment. Practice of educational actions regarding this subject was reported by 48.5% of those interviewed. CONCLUSION: This study reinforces the need to develop qualifying actions for nurses, so that strategies to control breast cancer become effective in their health care practice. PMID:25806636

    Tumor microenvironment composition and architecture are known as a major factor in orchestrating the tumor growth and its response to various therapies. In this context, in vivo studies are necessary to evaluate the responses. However, while tumor cells can be of human origin, tumor microenvironment in the in vivo models is host-based. On the other hand, in vitro studies in a flat monoculture of tumor cells (the most frequently used in vitro tumor model) are unable to recapitulate the complexity of tumor microenvironment. Three-dimensional (3D) in vitro cell cultures of tumor cells have been proven to be an important experimental tool in understanding mechanisms of tumor growth, response to therapeutics, and transport of nutrients/drugs. We have recently described a novel tool to create 3D co-cultures of tumor cells and cells in the tumor microenvironment. Our method utilizes magnetic manipulation/levitation of the specific ratios of tumor cells and cells in the tumor microenvironment (from human or animal origin) aiding in the formation of tumor spheres with defined cellular composition and density, as quickly as within 24 h. This chapter describes the experimental protocols developed to model the 3D structure of the cancer environment using the above method.

    2012-02-01

    INTRODUCTION: Breast-conserving surgery (BCS), followed by appropriate adjuvant therapies is established as a standard treatment option for women with early-stage invasive breast cancers. A number of factors have been shown to correlate with local and regional disease recurrence. Although margin status is a strong predictor of disease recurrence, consensus is yet to be established on the optimum margin necessary. Margenthaler et al. recently proposed the use of a "margin index," combining tumor size and margin status as a predictor of residual disease after BCS. We applied this new predictive tool to a population of patients with primary breast cancer who presented to a symptomatic breast unit to determine its suitability in predicting those who require reexcision surgery. METHODS: Retrospective analysis of our breast cancer database from January 1, 2000 to June 30, 2010 was performed, including all patients who underwent BCS. Of 531 patients who underwent BCS, 27.1% (144\\/531) required further reexcision procedures, and 55 were eligible for inclusion in the study. Margin index was calculated as: margin index = closest margin (mm)\\/tumor size (mm) x 100, with index >5 considered optimum. RESULTS: Of the 55 patients included, 31% (17\\/55) had residual disease. Fisher\\'s exact test showed margin index not to be a significant predictor of residual disease on reexcision specimen (P = 0.57). Of note, a significantly higher proportion of our patients presented with T2\\/3 tumors (60% vs. 38%). CONCLUSIONS: Although an apparently elegant tool for predicting residual disease after BCS, we have shown that it is not applicable to a symptomatic breast unit in Ireland.

    Full Text Available Aim To investigate the presence and expression levels of the IL-18 in the primary breast cancer tissue in relation to the unchangedbreast tissue in same patients and the breast tissue in patients withbenign breast disease, as well as the correlation between the IL-18 expression levels and pathohistological factors, including thecorrelation between IL-18 expression and the estrogens and progesterone receptor status. Methods This prospective randomized study was conducted at the Policlinic for Laboratory Diagnostics of the University Clinical Centre of Tuzla. 50 patients with invasive ductal breast cancer and 20 patients with benign breast diseases were included in the study. The tree-step immunohistochemical staining was used for testing the levels of IL-18 expression and hormone receptor status. Results IL-18 was present in the breast cancer tumour, in the surrounding unchanged tissue of the same patients and in the breast tissue of patients with benign breast tumour and other benign breast disease. The expression of this interleukin was signiicantly higher in breast cancer tumour tissue as compared to its expression in surrounding unchanged tissue of the same patients (p<0,05, whereas IL-18 expression was not signiicantly higher in breast cancer tumours compared to its expression in breast tissue of the patients with benign breast diseases (p=0,057. There was no signiicant correlation between IL-18 expression and the lymph node status, and between IL-18 expression and the pathohistological factors. Conclusion The results suggest possible involvement of IL-18 in complex mechanisms of breast carcinogenesis.

    Full Text Available Pooja Advani, Alvaro Moreno-AspitiaDepartment of Hematology and Oncology, Mayo Clinic, Jacksonville, FL, USAAbstract: Due to the high incidence of breast cancer in the United States, optimal strategies for its prevention are imperative. This entails identification of women who are at an increased risk for breast cancer and an integrative approach that includes effective screening methods as well as nutritional, pharmacologic, and surgical management. Several breast cancer risk-assessment tools, such as the Gail and Claus models, can help clinicians determine the quantitative risk of breast cancer. The role of selective estrogen receptor modulators, such as tamoxifen and raloxifene, for the prevention of breast cancer has been well established. Several other agents, such as aromatase inhibitors, are currently being investigated. The potential adverse effects of these chemopreventive agents, which include an impact on the quality of life, must be discussed with the patient before deciding on this approach. Additionally, breast cancer risk factors have been identified over the years; some of them are modifiable, but others are not. Although there is no conclusive evidence to suggest the protective role of specific dietary components, alcohol consumption and obesity are associated with an increased breast cancer risk; thus lifestyle changes can lead to a lower risk of developing breast cancer. Surgical approaches, including bilateral risk-reduction mastectomy and salpingo-oophorectomy, are usually limited to women with a hereditary predisposition to development of breast cancer. The objective of this review is to summarize the various approaches directed at reducing the incidence of breast cancer.Keywords: chemoprevention, tamoxifen, raloxifene, prophylactic surgery

  10. Stem cells in normal mammary gland and breast cancer.

    Luo, Jie; Yin, Xin; Ma, Tao; Lu, Jun

    2010-04-01

    The mammary gland is a structurally dynamic organ that undergoes dramatic alterations with age, menstrual cycle, and reproductive status. Mammary gland stem cells, the minor cell population within the mature organ, are thought to have multiple functions in regulating mammary gland development, tissue maintenance, major growth, and structural remodeling. In addition, accumulative evidence suggests that breast cancers are initiated and maintained by a subpopulation of tumor cells with stem cell features (called cancer stem cells). A variety of methods have been developed to identify and characterize mammary stem cells, and several signal transduction pathways have been identified to be essential for the self-renewal and differentiation of mammary gland stem cells. Understanding the origin of breast cancer stem cells, their relationship to breast cancer development, and the differences between normal and cancer stem cells may lead to novel approaches to breast cancer diagnosis, prevention, and treatment.

    The incidence of breast cancer and mortality from this disease remain high in countries with limited resources such as the Ukraine. Because of a lack of mammography equipment and formal screening programs, as well as educational and other factors, breast cancer is usually diagnosed in late stages in such countries. We report the experience of the PATH Breast Cancer Assistance Program in introducing a pilot breast cancer screening program in one territory of the Ukraine, the Chernihiv oblast. The program entailed educating the public, training health care providers in clinical breast examination (CBE) and mammography, opening a dedicated mammography facility, designating a center for breast cancer care, building diagnostic capacity, and fostering the formation of support groups. From 1998 to 2002, 18,000 women underwent screening with CBE and 8778 women underwent screening with mammography. When implementing the program we encountered various cultural, economic, and logistic difficulties, such as reservations about showing bare breasts in educational materials, the lack of an established system for collecting screening data, and barriers to follow-up in women with positive screening results. Screening mammography proved to be more effective in detecting small and nonpalpable lesions; 8.7% of cancers detected in the mammography group were in situ, compared with 0% in the CBE group. However, introduction of CBE as a screening modality required fewer financial resources compared with mammography and was recommended as a transitional method before the introduction of mammography screening programs in countries with limited resources. The introduction of screening was associated with favorable changes in indicators of breast cancer care, including an increase in the percentage of breast-preserving operations and new legislation to provide funding for breast cancer services. We conclude that this successful pilot program of breast cancer screening in a limited

    2010-01-01

    Breast cancer is the commonest malignancy among Singapore women, accounting for 29.7% of all female cancers, with an age-standardized rate of 54.9 per 100,000 per year. It has been the most frequent cancer in Singapore women for the last 30 years, with the highest rates previously reported in those aged between 45 and 49 years, but with a more recent observation of a change in peak age group to women in their late 50s. About 1,100 new cases are diagnosed annually and approximately 270 women die in Singapore each year from breast cancer. In the multiethnic population of Singapore, it has been noted that rising breast cancer incidence is consistent across all three ethnic groups (Chinese, Malays, and Indians). Singapore has among the highest breast cancer incidence in Asia. Possible explanations include rapid urbanization, improvement in socio-economic status, and adoption of a western lifestyle. Our experience with the Singapore breast screening pilot project (1994-1997) and the national breast-screening program (BreastScreen Singapore) has led to increased understanding of this disease in the country. Data from the pilot project showed that breast screening is just as effective in a predominantly Asian population as in the west. Early breast cancer accounted for most breast cancers detected, with pre-invasive ductal carcinoma in situ (DCIS) comprising 26% of all screen-detected cancers in the pilot study. In the currently on-going BreastScreen Singapore, DCIS forms >30% of all breast cancers among pre-menopausal women, a relatively high proportion probably accounted for partially by the greater participation of women aged between 40 and 49 years. Despite the ready availability of subsidized mammographic screening, there are still women in Singapore who present with locally advanced breast cancer. Clinical management of an increasing number of women with breast cancer embraces a multidisciplinary team-based approach, with regular discussions of therapeutic

    Objective The aim of this study was to investigate the application of mammography combined with breast dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for the diagnosis of early breast cancer. Methods Mammography and DCE-MRI were performed for 120 patients with breast cancer (malignant, 102; benign; 18). Results The sensitivity of mammography for early diagnosis of breast cancer was 66.67%, specificity was 77.78%, and accuracy was 68.33%. The sensitivity of MRI for early diagnosis of breast cancer was 94.12%, specificity was 88.89%, and accuracy was 93.33%. However, the sensitivity of mammography combined with DCE-MRI volume imaging with enhanced water signal (VIEWS) scanning for early diagnosis of breast cancer was 97.06%, specificity was 94.44%, and accuracy was 96.67%. Conclusion Mammography combined with DCE-MRI increased the sensitivity, specificity, and accuracy of diagnosing early breast cancer.

    Full Text Available Mammography, clinical breast-examination (CBE and breast self-examination (BSE are the mainly recommended screening methods for early diagnosis of breast cancer. In recent years, guidelines concerning screening methods were revised. To date, CBE and BSE are not routinely recommended for early diagnosis of breast cancer in western countries. Due to important value in decreasing breast cancer mortality rate, mammography, is the recommended breast cancer screening method; but the changes related with the time of mammography screening is rised to notice. In 2010, the US Preventive Services Task Force (USPSTF which is one of the important health authority, guidelines concerning screening mammography were revised. Accordingly, while the mammography that is recommended for women starting aged 40 years by many health authorities, the USPSTF no longer advises routine screening mammography for women aged 40–49 and for those aged ≥75.; and biennial screening is advised for those aged 50–74. It is necessary for health professionals working in breast health area to learn the last changes concerning about breast cancer screening methods. Together with CBE and BSE, it is also important to encourage women to participate mammography screening with an understanding of its benefits and risks. In this article, it is aimed to critique new guidelines about breast cancer screening methods. It is also critiqued the potential benefits and risks of mammography that is currently considered the ‘‘gold standard’’ for breast cancer screening for women.

    Breast cancer is the most prevalent women's cancer, with an age-adjusted incidence of 122.9 per 100,000 US women. Cadmium, a ubiquitous carcinogenic pollutant with multiple biological effects, has been reported to be associated with breast cancer in one US regional case-control study. We examined the association of breast cancer with urinary cadmium (UCd), in a case-control sample of women living on Long Island (LI), NY (100 with breast cancer and 98 without), a region with an especially high rate of breast cancer (142.7 per 100,000 in Suffolk County) and in a representative sample of US women (NHANES 1999-2008, 92 with breast cancer and 2,884 without). In a multivariable logistic model, both samples showed a significant trend for increased odds of breast cancer across increasing UCd quartiles (NHANES, p=0.039 and LI, p=0.023). Compared to those in the lowest quartile, LI women in the highest quartile had increased risk for breast cancer (OR=2.69; 95% CI=1.07, 6.78) and US women in the two highest quartiles had increased risk (OR=2.50; 95% CI=1.11, 5.63 and OR=2.22; 95% CI=.89, 5.52, respectively). Further research is warranted on the impact of environmental cadmium on breast cancer risk in specific populations and on identifying the underlying molecular mechanisms.

    Objective: To find an effective, sensitive, specific and noninvasive diagnostic method of breast cancer. Methods: 109 masses of 102 patients with breast lesions smaller than 2 cm in diameter were divided into three groups to undergo 99mTc-MIBI imaging and compared with the results of pathology examination. 20 cases without breast lesions were selected as control. Abnormal condensation of 99mTc-MIBI in the breast reaching 10% higher than that in the counterpart of the healthy breast was regarded as positive. Results: Of 32 breast cancers, positive imaging appeared in 25. Negative imaging were found in 31 of 38 benign breast lesions. Of 39 occult breast lesions, positive imaging appeared in 6 and 3 of them were breast cancer, 2 of 3 patients with slightly increased 99mTc-MIBI imaging threshold were breast cancer also. No positive imaging was found in the control group. The diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value of 99mTc-MIBI was 88.4%, 89.2%, 88.0%, 75.0% and 95.3%, respectively. Conclusion: 99mTc-MIBI imaging had higher sensitivity and accuracy in the diagnosis of breast cancer and differentiation between benign and malignant breast lesions. It could provide useful information for the diagnosis of clinically suspected breast cancer.

    Full Text Available OBJECTIVE: Oral health can affect a patient’s general health and quality of life. Given the increase in breast cancer survival rates, investigations of factors influencing the quality of life of survivors have gained importance. Therefore, the objective of our study was to characterize oral health in postmenopausal breast cancer survivors. METHODS: We conducted a matched case-control study. Forty-eight women who survived breast cancer (age 62.1±9.1 years and 48 healthy controls (age 61.8±8.6 years were included. For each case and control, a complete oral evaluation chart was completed. RESULTS: The prevalence of chronic periodontal disease was 98% in breast cancer survivors and 87% in controls. The breast cancer survivors had a median of 16 remaining teeth, whereas controls had a median of 22 remaining teeth (p = 0.03. The percentage of sites with gingival bleeding was 16.05% (0-100% in breast cancer survivors and 0% (0-72% in controls (p = 0.04. CONCLUSION: Chronic periodontal disease and tooth loss were highly prevalent in postmenopausal breast cancer survivors. To improve survivors’ quality of life, a preventive oral health evaluation should be available prior to cancer treatment.

We studied the association between breast cancer risk and polymorphisms in genes that code for GNRH1 and its receptor (GNRHR in the large National Cancer Institute Breast and Prostate Cancer Cohort Consortium (NCI-BPC3. Methods We sequenced exons of GNRH1 and GNRHR in 95 invasive breast cancer cases. Resulting single nucleotide polymorphisms (SNPs were genotyped and used to identify haplotype-tagging SNPs (htSNPS in a panel of 349 healthy women. The htSNPs were genotyped in 5,603 invasive breast cancer cases and 7,480 controls from the Cancer Prevention Study-II (CPS-II, European Prospective Investigation on Cancer and Nutrition (EPIC, Multiethnic Cohort (MEC, Nurses' Health Study (NHS, and Women's Health Study (WHS. Circulating levels of sex steroids (androstenedione, estradiol, estrone and testosterone were also measured in 4713 study subjects. Results Breast cancer risk was not associated with any polymorphism or haplotype in the GNRH1 and GNRHR genes, nor were there any statistically significant interactions with known breast cancer risk factors. Polymorphisms in these two genes were not strongly associated with circulating hormone levels. Conclusion Common variants of the GNRH1 and GNRHR genes are not associated with risk of invasive breast cancer in Caucasians.

    Full Text Available Background: Sexual dysfunction in breast cancer patients is considered as a common and distressing problem. Considering the increasing number of breast cancer survivors living for longer periods of time with the disease and the importance of their quality of life, we conducted the present study to compare the sexual functioning in breast cancer patients with their healthy counterparts.Methods: In this case-control study, breast cancer patients who completed their treatment protocol and were followed up for at least six months were included. The controls were healthy women with normal clinical breast examinations. All subjects filled-in the Persian version of Female Sexual Function Index questionnaire.Results: A total of 165 subjects including 71 breast cancer patients and 94 healthy women were studied. The frequency of sexual dysfunction in cases and controls was 52.6% and 47.4%, respectively (P = 0.09. There were no significant differences between the two groups regarding domain scores, except for vaginal lubrication (P = 0.045. Logistic regression analysis indicated that significant determinants of sexual dysfunction in breast cancer group was patients' age (OR = 4.0, 95%CI: 1.3 – 11.5, P = 0.01 and age of the spouse (OR= 9.8, 95% CI: 1.8-51.9, P= 0.007, while in controls, only emotional relationship with the husband was the significant predictive factor (OR = 6.3, 95%CI: 1.9 – 20.5, P = 0.002.Conclusions: Our findings indicated that sexual dysfunction is prevalent in Iranian women regardless of their physical health status. The frequency of vaginal dryness in breast cancer patients was significantly higher than controls. Age of the patient and the spouse (>40 were the only significant predictors of sexual dysfunction among women with breast cancer. Preventive strategies, sexual education and access to effective treatment should be planned in supportive care of breast cancer patients.

    The aim of our study was to estimate oxidative stress (by using different biomarkers of lipid peroxidation--isoprostanes and thiobarbituric acid reactive substances (TBARS)) in patients with invasive breast cancer, patients with benign breast diseases and in a control group. We observed a statistically increased level of TBARS in plasma and isoprostanes in urine of patients with invasive breast cancer in comparison with a control group. The concentration of tested biomarkers in plasma or urine from patients with invasive breast cancer was also higher than in patients with benign breast diseases. Moreover, the levels of tested markers in patients with benign breast diseases and in a control group did not differ. Considering the data presented in this study, we suggest that free radicals induce peroxidation of unsaturated fatty acid in patients with breast cancer.

    Objective: To investigate the molecular etiology of breast cancer by way of studying the differential expression and initial function of the related genes in the occurrence and development of breast cancer. Methods: Two hundred and eighty-eight human tumor related genes were chosen for preparation of the oligochips probe. mRNA was extracted from 16 breast cancer tissues and the corresponding normal breast tissues, and cDNA probe was prepared through reverse-transcription and hybridized with the gene chip. A laser focused fluorescent scanner was used to scan the chip. The different gene expressions were thereafter automatically compared and analyzed between the two sample groups. Cy3/Cy5>3.5 meant significant up-regulation. Cy3/Cy5<0.25 meant significant down-regulation. Results: The comparison between the breast cancer tissues and their corresponding normal tissues showed that 84 genes had differential expression in the Chip. Among the differently expressed genes, there were 4 genes with significant down-regulation and 6 with significant up-regulation. Compared with normal breast tissues, differentially expressed genes did partially exist in the breast cancer tissues. Conclusion: Changes in multi-gene expression regulations take place during the occurrence and development of breast cancer; and the research on related genes can help understanding the mechanism of tumor occurrence.

    1984-03-01

    The relationship between diazepam and breast cancer was evaluated using data from a case-control study of breast cancer, in which 1075 cases and 1146 controls who were participants in a breast cancer screening program were interviewed. Diazepam use was negatively associated with extent of disease and lymph node involvement, and this effect seemed greatest for long-term users of diazepam. It is not certain to what extent these data reflect an ascertainment bias, an association with the reasons for which the drug was prescribed, or chance. Whatever the explanation, the findings do not support a previous contention that diazepam promotes or accelerates breast cancer growth.

    Full Text Available Abstract Background Multidisciplinary attempts to understand the etiology of breast cancer are expanding to increasingly include new potential markers of disease risk. Those efforts may have maximal scientific and practical influence if new findings are placed in context of the well-understood lifestyle and reproductive risk factors or existing risk prediction models for breast cancer. We therefore evaluated known risk factors for breast cancer in a cancer screening trial that does not have breast cancer as a study endpoint but is large enough to provide numerous analytic opportunities for breast cancer. Methods We evaluated risk factors for breast cancer (N = 2085 among 70,575 women who were randomized in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Using Poisson regression, we calculated adjusted relative risks [RRs, with 95% confidence intervals (CIs] for lifestyle and reproductive factors during an average of 5 years of follow-up from date of randomization. Results As expected, increasing age, nulliparity, positive family history of breast cancer, and use of menopausal hormone therapy were positively associated with breast cancer. Later age at menarche (16 years or older vs. 2 35 or more vs. 18.5–24.9: RR = 1.21, 95% CI, 1.02–1.43] was statistically significantly associated with breast cancer. Conclusion The ongoing PLCO trial offers continued opportunities for new breast cancer investigations, but these analyses suggest that the associations between breast cancer and age at menarche, age at menopause, and obesity might be changing as the underlying demographics of these factors change.

  17. Breast cancer management: Past, present and evolving

    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.

  18. Accessory breast tissue in axilla masquerading as breast cancer recurrence

    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.

    Breast self-examination (BSE) is a self-generated, non-invasive and non-irradiative method of breast cancer detection. This paper documents Malaysian women's awareness and practice of regular BSE as a potent breast cancer detection tool. A pre-test post-test questionnaire survey on women diagnosed with breast cancer (n=66) was conducted. Descriptive statistics and Chi-square tests were performed to correlate demographic variables, knowledge and regular practice of BSE. Findings showed that 80% of the breast cancer survivors self-detected the breast lumps, despite a high 85% of these women reporting they were never taught about BSE. More than 70% of the women maintained that lack of knowledge/skill on the proper practice of BSE was the key barrier to a more regular BSE practice. After an educational intervention on BSE and breast awareness, we found an increase report from 17% (at pre-test) to 67% (at post-test) of self reported monthly BSE practices. Provision of self-management education incorporating BSE, a readily available cheap method, should be introduced at primary care and breast clinics. This strategy promotes women's self-efficacy which contributes towards cancer control agenda in less resource available countries around Asia Pacific. Longer follow up may be crucial to examine the adherence to positive BSE behaviour.

    Treatment options as well as the characteristics for therapeutic decisions in patients with primary and advanced breast cancer are increasing in number and variety. New targeted therapies in combination with established chemotherapy schemes are broadening the spectrum, however potentially promising combinations do not always achieve a better result. New data from the field of pharmacogenomics point to prognostic and predictive factors that take not only the properties of the tumour but also inherited genetic properties of the patient into consideration. Current therapeutic decision-making is thus based on a combination of classical clinical and modern molecular biomarkers. Also health-economic aspects are more frequently being taken into consideration so that health-economic considerations may also play a part. This review is based on information from the recent annual congresses. The latest of these are the 34th San Antonio Breast Cancer Symposium 2011 and the ASCO Annual Meeting 2012. Among their highlights are the clinically significant results from the CLEOPATRA, BOLERO-2, EMILIA and SWOG S0226 trials on the therapy for metastatic breast cancer as well as further state-of-the-art data on the adjuvant use of bisphosphonates within the framework of the ABCSG-12, ZO-FAST, NSABP-B34 and GAIN trials.

  1. [THE EFFECT OF PREGNANCY ON BREAST CANCER].

    Cancer and pregnancy coincide in about one in 1,000 pregnancies. One of the most common malignancies associated with pregnancy is breast cancer. Women with pregnancy-associated breast cancer (PABC) have a higher likelihood of being diagnosed with metastatic disease and estrogen receptor (ER) negative tumors than do non-pregnant women. Controversies exist regarding the effect of pregnancy on breast cancer prognosis. Some researchers suggest that pregnancy does not affect breast cancer prognosis, whereas others claim the opposite. Although PABC is usually discovered in an advanced stage, breast cancer metastasis on the placenta is a rare event. During cancer progression, the surrounding microenvironment co-evolves into an activated state through continuous communication with the malignant cells, thereby promoting tumor growth. The effect of pregnancy and placental environment on breast cancer biology is the issue of this review. Placental and cancer cells implantation processes share similar molecular pathways. This suggests that placental factors may affect breast cancer cells biology. Previously, we analyzed the effect of first trimester human placenta on breast cancer cells. Breast cancer cells were co-cultured with placental explants during their implantation on matrigel substrate. We found that the placenta reduced ER expression on the cancer cells and induced their migration and invasion abilities. As a result of it, breast cancer cells migrated away from the placental implantation sites. Hormonal pathways were involved in these phenomena. These results may explain the high incidence of metastases during pregnancy in on the one hand and the rarity of metastases on the placenta on the other hand.

    Objective: Survivin is a member of the inhibitor of apoptosis (IAP) family, and is involved in the regulation of cell division. E-cadherin functionally belongs to transmembrane glycoproteins family, it is responsible for intercellular junction mechanism that is crucial for the mutual association of vertebrate cells. These genes are thought to be associated with cancer aggression. This study was to investigate the relationship between surviving gene, E-cadherin expression and invasion clinicopathological features of breast cancer. Methods: The expression of surviving gene and E-cadherin were detected by SP immunohistochemical technique in tissues of 66 breast cancer, 20 breast fibroadenoma and 20 adjacent breast tissue. Results: The positive rate of surviving gene expression in breast cancer was 42.2%, significantly higher (P=0.025) than those in breast fibroadenoma (35.0%), and adjacent breast tissue (10.0%). The positive rate of E-cadherin in the groups of adjacent breast tissue, breast fibroadenoma and breast cancer were 100%, 100% and 42.4%, there was significant difference between the group of benign and malignant tumor (P=0.005). The positive rate of surviving in breast cancer with local lymph node metastasis was significant higher than that in breast cancer without lymph node metastasis (P=0.01), and E-cadherin in breast cancer with local lymph node metastasis was significant lower than that without lymph node metastasis (P=o.o1). There was no significant difference among the groups of pathological types and TNM stages in the expression of surviving (P=0.966 & P=0.856), but there was significant difference in the expression of E-cadherin among these groups (P=0.01 & P=0.023). Conclusion: The loss or decrease of E-cadherin expression may promote the exfoliation of cancerous cells from original tissues, and surviving gene may promote the viability of the exfoliated cancer cells and the formation of new metastasis focus. These 2 factors cooperate with each other

    The collection of large volumes of medical data has offered an opportunity to develop prediction models for survival by the medical research community. Medical researchers who seek to discover and extract hidden patterns and relationships among large number of variables use knowledge discovery in databases (KDD) to predict the outcome of a disease. The study was conducted to develop predictive models and discover relationships between certain predictor variables and survival in the context of breast cancer. This study is Cross sectional. After data preparation, data of 22,763 female patients, mean age 59.4 years, stored in the Surveillance Epidemiology and End Results (SEER) breast cancer dataset were analyzed anonymously. IBM SPSS Statistics 16, Access 2003 and Excel 2003 were used in the data preparation and IBM SPSS Modeler 14.2 was used in the model design. Support Vector Machine (SVM) model outperformed other models in the prediction of breast cancer survival. Analysis showed SVM model detected ten important predictor variables contributing mostly to prediction of breast cancer survival. Among important variables, behavior of tumor as the most important variable and stage of malignancy as the least important variable were identified. In current study, applying of the knowledge discovery method in the breast cancer dataset predicted the survival condition of breast cancer patients with high confidence and identified the most important variables participating in breast cancer survival.

    Objective To investigate the diagnostic and prognostic value of total and free prostate-specific antigen (PSA) in breast cancer women. Methods Using the microparticle enzyme immunoassay system, we measured the concentrations of these markers in the sera of 85 women with breast cancer and in 30 healthy women.Results Free PSA levels were significantly higher in women with breast cancer than healthy women (P <0. 05 ).The percentage of free PSA predominant subjects was 37. 6% in breast cancer patients and 3. 3% in healthy women.In women with breast cancer,total PSA positivity was 23.5% and free PSA positivity was 27. 1%. When compared to negatives,total PSA positive patients had a higher percentage of lymph node involvement tamours ( P >0. 05).However, patients with predominant free PSA had a higher percentage of early stage than patients with predominant PSA-ACT. Conclusion This study indicate clinical significance of preoperative measurement of serum total and free PSA in diagnosis and prognosis of women with breast cancer. The expression of KLKs is correlated with carcinogenesis of breast cancer.

    Full Text Available Nuclear receptors play an important role in transcriptional regulation of diverse cellular processes and is also relevant in diseases such as cancer. In breast cancer, the nuclear receptors – estrogen receptor (ER and progesterone receptor (PR are classical markers of the disease and are used to classify breast cancer subtypes. Using a recently developed affinity purification MS technique (RIME [1], we investigate the protein interactors of ER and PR in breast cancer cell lines upon stimulation by the ligands – estrogen and progesterone. The data is deposited at proteomeXchange (PXD002104 and is part of a publication [2] that explains the link between the two nuclear receptors and potential consequences of this in breast cancer. In this manuscript, we describe the methodology used and provide details on experimental procedures, analysis methods and analysis of raw data. The purpose of this article is to enable reproducibility of the data and provide technical recommendations on performing RIME in hormonal contexts.

    2012-11-01

    Full Text Available Abstract Background Breast cancer is one of the leading causes of cancer morbidity and mortality worldwide. In Cameroon, breast cancer causes as many as 10.7 deaths per 100,000 women making it the second cause of cancer mortality. Better documenting women’s knowledge and practices on breast cancer and breast self-exam (BSE would be useful in the design of interventions aimed at preventing breast cancer. This study sought to 1. describe Cameroonian women’s knowledge of breast self-examination (BSE; 2. assess their impression on the practice of BSE and 3. describe their perceptions on the causes, risk factors and prevention of breast cancer. Methods A cross-sectional survey was conducted in a volunteer sample of 120 consenting women in Buea, Cameroon. Data were collected using a structured questionnaire self-administered by study participants. Results The sample was fairly educated with close to three quarters (70.83% having completed high school. Nearly three quarters (74.17% of participants had previously heard about BSE, however as many as 40% had never done a BSE. Although 95% of participants believed that breast cancer could be prevented, only 36.67% recognized breast examination as a prevention method. A substantial 13.33% thought that breast cancer could be prevented with a vaccine while 45% thought that dieting or exercising would prevent breast cancer. Similarly, 70% of participants thought that breast cancer could be treated, with 35.83% thinking that it could be treated medically while 34.17% thought it could be treated traditionally or spiritually. Conclusions The practice of BSE while perceived as being important is not frequent in these women in Buea, Cameroon. Health education campaigns are imperative to elucidate the public on the causes, risk factors and prevention of breast cancer. Further studies need to explore what interventions could be best used to improve the uptake and practice of BSE.

    We evaluated individual grain-containing foods and whole and refined grain intake during adolescence, early adulthood, and premenopausal years in relation to breast cancer risk in the Nurses' Health Study II. Grain-containing food intakes were reported on a baseline dietary questionnaire (1991) and every 4 years thereafter. Among 90,516 premenopausal women aged 27-44 years, we prospectively identified 3235 invasive breast cancer cases during follow-up to 2013. 44,263 women reported their diet during high school, and from 1998 to 2013, 1347 breast cancer cases were identified among these women. Cox proportional hazards regression was used to estimate relative risks (RR) and 95 % confidence intervals (95 % CI) of breast cancer for individual, whole and refined grain foods. After adjusting for known breast cancer risk factors, adult intake of whole grain foods was associated with lower premenopausal breast cancer risk (highest vs. lowest quintile: RR 0.82; 95 % CI 0.70-0.97; P trend = 0.03), but not postmenopausal breast cancer. This association was no longer significant after further adjustment for fiber intake. The average of adolescent and early adulthood whole grain food intake was suggestively associated with lower premenopausal breast cancer risk (highest vs lowest quintile: RR 0.74; 95 % CI 0.56-0.99; P trend = 0.09). Total refined grain food intake was not associated with risk of breast cancer. Most individual grain-containing foods were not associated with breast cancer risk. The exceptions were adult brown rice which was associated with lower risk of overall and premenopausal breast cancer (for each 2 servings/week: RR 0.94; 95 % CI 0.89-0.99 and RR 0.91; 95 % CI 0.85-0.99, respectively) and adult white bread intake which was associated with increased overall breast cancer risk (for each 2 servings/week: RR 1.02; 95 % CI 1.01-1.04), as well as breast cancer before and after menopause. Further, pasta intake was inversely associated with

    Male breast cancer (MBC) is an uncommon and poorly understood disease. Recent molecular studies have shown important differences from female breast cancer which are likely to influence treatment strategies from the current female-based management towards a more tailored approach. Significantly more MBCs than female breast cancers arise with an underlying germline cancer predisposition, and display a vastly different penetrance compared with females. Furthermore, the genophenotypical association of basal-like cancer with BRCA1 present in female breast cancer is not observed in male breast cancer. Differences in somatic changes between male and female breast cancer have also been reported, with particular enrichment of PIK3CA mutations and a paucity of TP53 mutations. In general, chromosomal-based changes, in particular regions of gains, are seen more frequently in male than female breast cancer and methylation is seen less frequently. Clinically, several molecular subtypes with prognostic relevance have been described, including chromosomal complex high and methylation high groups, and subgroups with profiling signatures pertaining to epithelial mesenchymal transition and hormonal therapy insensitivity. As with female breast cancer, attention to male specific multicentre trials based on the individual characteristics are needed, together with establishment of reliable preclinical models to understand more clearly the pathogenesis of male breast cancer and improve the general poor outcome of this disease.

    Interleukin-8 (IL-8) is a chemokine that has an autocrine and/or paracrine tumor-promoting role and significant potential as a prognostic and/or predictive cancer biomarker. In breast cancer, which is mostly determined by expression of estrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2), IL-8 could play a specific role. IL-8 is highly expressed in ER- breast cancers, but it increases invasiveness and metastatic potential of both ER- and ER+ breast cancer cells. It is also highly expressed in HER2+ breast cancers. Because of the complex crosstalk between these receptors and IL-8, its role is mainly determined by delicate balance in their signaling pathways. Therefore, the main point of this review was to analyze the possible influence of IL-8 in breast cancer progression related to its interaction with ER and HER2 and the consequent therapeutic implications of these relations.

    Despite the dramatic advances in breast cancer treatment over the past two decades, it is still the most common malignancies in women. One of the reasons patients succumb to breast cancer is treatment resistance leading to metastasis and recurrence. Recently, cancer stem cells (CSCs) have been suggested as a cause of metastasis and recurrence in several cancers because of their unique characteristics, including self-renewal, pluripotency, and high proliferative ability. Increasing evidence has implicated breast cancer stem cells (BCSCs) as essential for tumor development, progression, recurrence, and treatment resistance. BCSCs exhibit resistance to treatment owing to several inter-related factors, including overexpression of ATP-binding cassette (ABC) transporters and increased aldehyde dehydrogenase (ALDH) activity, DNA repair, and reactive oxygen species (ROS) scavenging. In addition, the Notch, Hedgehog, and Wnt signaling pathways have been suggested as the major pathways involved in the self-renewal and differentiation of BCSCs. Despite growing evidence suggesting the importance of BCSCs in progression and metastasis, clear criteria for the identification of BCSCs in clinical practice have yet to be established. Several potential markers have been suggested, including CD44+/CD24−/low, ALDH1, EpCAM/ESA, and nestin; however, there is no standard method to detect BCSCs. Triple-negative breast cancer, which shows initial chemosensitivity, demonstrates worsened prognosis due to therapy resistance, which might be related to the presence of BCSCs. Several clinical trials aimed at the identification of BCSCs or the development of BCSC-targeted therapy are in progress. Determining the clinical relevance of BCSCs may provide clues for overcoming therapy resistance in breast cancer. PMID:28210556

    Abstract Background: Diabetes mellitus is associated with an increased risk of breast cancer, but studies of the effects of diabetes on the prognosis of women with breast cancer have yielded inconsistent findings. The present meta-analysis aimed to investigate the impact of preexisting diabetes on the prognosis in terms of overall survival (OS), disease-free survival (DFS), and relapse-free period (RFP) in women with breast cancer. Methods: We searched the Embase and PubMed databases until June 2016 for cohort or case–control studies assessing the impact of diabetes on the prognosis of women with breast cancer. The pooled multivariate adjusted hazard ratio (HR) and their 95% confidence intervals (CIs) for OS, DFS, and RFP were used to analyze the impact of diabetes on the prognosis of breast cancer patients. Results: Seventeen studies involving 48,315 women with breast cancer met our predefined inclusion criteria. Meta-analysis showed that the pooled adjusted HR was 1.51 (95% CI 1.34–1.70) for OS and 1.28 (95% CI 1.09–1.50) for DFS in breast cancer patients with diabetes compared to those without diabetes. However, RFP did not differ significantly between patients with and without diabetes (HR 1.42; 95% CI 0.90–2.23). Conclusions: The present meta-analysis suggests that preexisting diabetes is independently associated with poor OS and DFS in female breast cancer patients. However, the impact of diabetes on RFP should be further verified. More prospective studies are warranted to investigate whether appropriate glycemic control with modification of antihyperglycemic agents can improve the prognosis of female breast cancer patients with diabetes.

    Full Text Available Background. Breast cancer is a major public health issue and the most commonly diagnosed cancer for women worldwide. Despite lower incidence rates than those living in Western countries, breast cancer incidence among Chinese women has increased dramatically in the past 20 years. Nevertheless, there is a paucity of studies reporting the attitudes toward and practices of breast cancer screening among Chinese women. Methods. This cross-sectional study examined the practices, knowledge, and attitudes toward breast cancer screening (BCS on a convenience sample of 400 Chinese women. Results. Among study participants, 75% of the women never had a mammogram and the top three barriers reported were low priority, feeling OK, and lack of awareness/knowledge toward breast cancer screening. The results from the logistic regression model showed increased self-efficacy; having performed monthly self-exams, and having had clinical breast exams in the past two years were significant correlates while demographic variables were not correlated with screening behaviors. Conclusion. The findings provide a foundation to better understand beliefs and practices of Chinese women toward BCS and highlight the critical need for general public, health professionals, and the health care system to work collaboratively toward improving the quality of breast cancer care in this population.

  6. Impact of screening mammography on breast cancer mortality.

    Bleyer, Archie; Baines, Cornelia; Miller, Anthony B

    2016-04-15

    The degree to which observed reductions in breast cancer mortality is attributable to screening mammography has become increasingly controversial. We examined this issue with three fundamentally different approaches: (i) Chronology--the temporal relationship of the onset of breast cancer mortality decline and the national implementation of screening mammography; (ii) Magnitude--the degree to which breast cancer mortality declined relative to the amount (penetration) of screening mammography; (iii) Analogy--the pattern of mortality rate reductions of other cancers for which population screening is not conducted. Chronology and magnitude were assessed with data from Europe and North America, with three methods applied to magnitude. A comparison of eight countries in Europe and North America does not demonstrate a correlation between the penetration of national screening and either the chronology or magnitude of national breast cancer mortality reduction. In the United States, the magnitude of the mortality decline is greater in the unscreened, younger women than in the screened population and regional variation in the rate of breast cancer mortality reduction is not correlated with screening penetrance, either as self-reported or by the magnitude of screening-induced increase in early-stage disease. Analogy analysis of United States data identifies 14 other cancers with a similar distinct onset of mortality reduction for which screening is not performed. These five lines of evidence from three different approaches and additional observations discussed do not support the hypothesis that mammography screening is a primary reason for the breast cancer mortality reduction in Europe and North America.

    Full Text Available During pregnancy breast cancer is rarely seen. In this case, when the patient was being operated for the right breast cancer which was diagnosed in the first exam, a left breast cancer was also detected in the operation. When the patient analysed retrospectively, lesion in the left breast could not detected because of the lactation period. Consequently,pregnancy patients must be re-examined after the lactation period to avoid any possible mistakes. [Cukurova Med J 2013; 38(3.000: 492-494

    Fluorescent in situ hybridization (FISH) and immunohistochemistry (IHC) are the most common methods that are used to quantify HER-2 gene and protein levels, respectively, in human breast cancer. However, due to bad sample quality, some samples are unable to be subjected to a FISH assay. We evaluated 71 formalin-fixed paraffin-embedded (FFPE) breast carcinoma specimens by quantitative real-time polymerase chain reaction (qPCR), IHC, and FISH. We also performed qPCR and FISH assays on delayed formalin-fixed (DDF) samples. The qPCR results were in complete concordance with the results of IHC and FISH. In regards to the DDF samples, the HER-2 fluorescent signal seemed decayed compared with that of the DDF samples after 1 h. However, the qPCR method still works well up to 12 hours. Our results indicated that qPCR was obviously superior to FISH in cases that were not fixed in a reasonable amount of time. However, qPCR can be an alternative method by which to perform HER2 amplification assays in breast cancer.

  11. Detection of circulating breast cancer cells using photoacoustic flow cytometry

    Science.gov (United States)

    Bhattacharyya, Kiran

    According to the American Cancer Society, more than 200,000 new cases of breast cancer are expected to be diagnosed this year. Moreover, about 40,000 women died from breast cancer last year alone. As breast cancer progresses in an individual, it can transform from a localized state to a metastatic one with multiple tumors distributed through the body, not necessarily contained within the breast. Metastasis is the spread of cancer through the body by circulating tumor cells (CTCs) which can be found in the blood and lymph of the diagnosed patient. Diagnosis of a metastatic state by the discovery of a secondary tumor can often come too late and hence, significantly reduce the patient's chance of survival. There is a current need for a CTC detection method which would diagnose metastasis before the secondary tumor occurs or reaches a size resolvable by current imaging systems. Since earlier detection would improve prognosis, this study proposes a method of labeling of breast cancer cells for detection with a photoacoustic flow cytometry system as a model for CTC detection in human blood. Gold nanoparticles and fluorescent polystyrene nanoparticles are proposed as contrast agents for T47D, the breast cancer cell line of choice. The labeling, photoacoustic detection limit, and sensitivity are first characterized and then applied to a study to show detection from human blood.

    Performance of binary classification of breast cancer suffers from high imbalance between classes. In this article we present the preprocessing module designed to negate the discrepancy in training examples. Preprocessing module is based on standardization, Synthetic Minority Oversampling Technique and undersampling. We show how each algorithm influences classification accuracy. Results indicate that described module improves overall Area Under Curve up to 10% on the tested dataset. Furthermore we propose other methods of dealing with imbalanced datasets in breast cancer classification.

    2016-01-01

    This book collates past and current research on one of the most promising emerging modalities for breast cancer detection. Readers will discover how, as a standalone technology or in conjunction with another modality, microwave imaging has the potential to provide reliable, safe and comfortable breast exams at low cost. Current breast imaging modalities include X- ray, Ultrasound, Magnetic Resonance Imaging, and Positron Emission Tomography. Each of these methods suffers from limitations, including poor sensitivity or specificity, high cost, patient discomfort, and exposure to potentially harmful ionising radiation. Microwave breast imaging is based on a contrast in the dielectric properties of breast tissue that exists at microwave frequencies. The book begins by considering the anatomy and dielectric properties of the breast, contrasting historical and recent studies. Next, radar-based breast imaging algorithms are discussed, encompassing both early-stage artefact removal, and data independent and adaptive ...

    Full Text Available Background: The primary objective was to examine and compare the breast cancer screening adherence rates between black (African American and Afro-Caribbean and Hispanic (foreign born Hispanic and US-born Hispanic subpopulations. Methods: Study data was collected in community settings in New York City between the years of 2011-2012. Participants (N=592 were black and Hispanic individuals who attended a breast cancer screening community outreach program. Breast cancer screening rates as well as demographic data were collected. Results: Results revealed that Afro-Caribbean and foreign-born Hispanics are at a greater risk for non-adherence in breast cancer screening compared with African Americans and US-born Hispanics. Conclusions: The majority of breast screening research and community outreach programs categorize people into broad racial and ethnic groups (e.g., black and Hispanic. The results revealed significant variability within these broader racial/ethnic categories with regard to breast cancer screening. Community outreach programs and future research efforts should target the subpopulations that are at particular risk for breast cancer screening non-adherence.

  2. Birth weight, breast cancer and the potential mediating hormonal environment.

    Directory of Open Access Journals (Sweden)

    Radek Bukowski

    Full Text Available BACKGROUND: Previous studies have shown that woman's risk of breast cancer in later life is associated with her infants birth weights. The objective of this study was to determine if this association is independent of breast cancer risk factors, mother's own birth weight and to evaluate association between infants birth weight and hormonal environment during pregnancy. Independent association would have implications for understanding the mechanism, but also for prediction and prevention of breast cancer. METHODS AND FINDINGS: Risk of breast cancer in relation to a first infant's birth weight, mother's own birth weight and breast cancer risk factors were evaluated in a prospective cohort of 410 women in the Framingham Study. Serum concentrations of estriol (E3, anti-estrogen alpha-fetoprotein (AFP, and pregnancy-associated plasma protein-A (PAPP-A were measured in 23,824 pregnant women from a separate prospective cohort, the FASTER trial. During follow-up (median, 14 years 31 women (7.6% were diagnosed with breast cancer. Women with large birth weight infants (in the top quintile had a higher breast cancer risk compared to other women (hazard ratio (HR, 2.5; 95% confidence interval (CI, 1.2-5.2; P = 0.012. The finding was not affected by adjustment for birth weight of the mother and traditional breast cancer risk factors (adjusted HR, 2.5; 95% CI, 1.2-5.6; P = 0.021. An infant's birth weight had a strong positive relationship with the mother's serum E3/AFP ratio and PAPP-A concentration during pregnancy. Adjustment for breast cancer risk factors did not have a material effect on these relationships. CONCLUSIONS: Giving birth to an infant with high birth weight was associated with increased breast cancer risk in later life, independently of mother's own birth weight and breast cancer risk factors and was also associated with a hormonal environment during pregnancy favoring future breast cancer development and progression.

    A prognostic classification for thermographic staging of breast cancer has been applied to a cohort of 70 patients from 5040 screenees enrolled in the Albert Einstein Medical Center (AEMC) Breast Cancer Detection Demonstration Project (BCDDP). A diagnosis of breast cancer was established in each case before December 31, 1980. None of the patients have been lost to follow-up which extended from a minimum of 6 to a maximum of 13 years. Survival rates for those with favorable, equivocal, and poor thermographic factors are compared with each other and with results in accordance with tumor-node-metastasis (TNM) classification. As of December 31, 1986, there have been 22 (31.4%) deaths, all attributed to breast cancer. The thermographic scoring system clearly shows shorter survival for patients with poor thermographic prognostic factors, 30% surviving at 5 years and only 20% at 10 years compared with overall survival of 80% at 5 years and 70% at 10 years.

    2005-01-01

    Breast cancer remains the most common malignancy among women in the Western world. Mammography, which is currently the main screening modality for early detection, has a low positive predictive value of only 25%, especially in young women with very dense breasts. Therefore, new screening approaches are needed for the early detection of breast cancer in all age groups. Mammary ductoscopy (MD) is a newly developed endoscopic technique that allows direct visualization and biopsy of the mammary ductal epithelium where most cancers originate. The procedure can be performed under local anesthesia in the office setting. At present, MD is used as a diagnostic adjunct in patients with pathological nipple discharge and to guide duct excision surgery. This article focuses on the potential of this technique in breast cancer screening and highlights its limitations in this context.

    Papa, V; Costantino, A; Belfiore, A

    1997-10-01

    It is commonly believed that the insulin receptor mainly mediates the metabolic effects of insulin, whereas the closely related IGF-I receptor is considered a major factor for the regulation of cell proliferation. Experimental and epidemiological evidence indicates, however, that insulin and insulin receptors may play an important role in breast cancer. This article reviews evidence indicating that (a) insulin receptors are overexpressed in human breast cancer, (b) insulin stimulates growth in breast cancer cells, (c) cells transfected with human insulin receptor may acquire a ligand-dependent transformed phenotype, and (d) breast cancer is associated with insulin resistance and hyperinsulinemia. These findings may open new possibilities in breast cancer prevention, prognosis assessment, and therapy. (Trends Endocrinol Metab 1997; 8:306-312). (c) 1997, Elsevier Science Inc.

    BACKGROUND: A variety of estimates of the benefits and harms of mammographic screening for breast cancer have been published and national policies vary. OBJECTIVES: To assess the effect of screening for breast cancer with mammography on mortality and morbidity. SEARCH STRATEGY: We searched Pub...... excluded a biased trial and included 600,000 women in the analyses. Three trials with adequate randomisation did not show a significant reduction in breast cancer mortality at 13 years (relative risk (RR) 0.90, 95% confidence interval (CI) 0.79 to 1.02); four trials with suboptimal randomisation showed...... a significant reduction in breast cancer mortality with an RR of 0.75 (95% CI 0.67 to 0.83). The RR for all seven trials combined was 0.81 (95% CI 0.74 to 0.87). We found that breast cancer mortality was an unreliable outcome that was biased in favour of screening, mainly because of differential...

    Full Text Available Background: Caregivers of individuals suffering from cancer illnesses are at risk of having subjected to mental health consequences. There is a paucity of data comparing the caregiver burden of cancer breast and cancer cervix patients. Aim: The aim of the present study is to compare the caregiver burden of cancer breast and cancer cervix patients. To study the association of caregiver burden with demographic factors like age, gender, duration of caregiving etc. Materials & Methods: This Cross sectional study is performed on the key relatives of patients of 31 cancer cervix and 31 cancer breast patients. Burden assessment schedule was used. Results: Our findings suggest burden is more in male caregivers of breast cancer patients. It is not so in caregivers of cancer cervix patients. Whenever the caregiver is closely related to the patients the burden is high in both groups. Whenever the burden scores were high the depression scores were also high. Treatment modalities as a whole correlates with burden scores in caregivers of breast cancer patients but not in cancer cervix patients. Conclusion: Caregivers with breast and cervical cancer patients are vulnerable if the caregiver is male, from low socioeconomical background, more closely related and when the patients received poor treatment modalities.

    Objectives. To investigate the genetic susceptibility for breast cancer of Chinese, a hospital-based case-control study, pedigree survey and molecular genetic study were conducted. Methods. Logistic regression model and stratification methods were used in the risk factors analysis. Li-Mantel art and Falconer methods were used to analyze the segregation ratio and heritability. Polymerase chain reaction (PCR) and polyacrylamide gel electrophoresis were used to detect AI, G-banding technique was used to detect the chromosome aberration of peripheral blood lymphocyte. Results. Family history of breast cancer is related to enhanced breast cancer risk significartly, OR is 3.905 ( 95 % CI = 1.079 ~ 14.13), and it widely interacts with other risk factors. Accumulative incidence of breast cancer in first degree relatives is 9.99%, which is larger than that in second, third degree and non-blood relatives. Segregation ratio is 0.021, heritability among first degree relatives is 35.6 ± 5.8%. Frequencies of LOH at BRCA1 and BRCA2 loci in sporadic breast cancer are 6.12% and 5.77% respectively. In the sibs, both of them show LOH at D13S173 locus, and high frequencies of chromosome aberrations were observed. Conclusions. Genetic susceptibility contributes to breast cancer occurrence of Chinese, and its racial variation may be one of the important reasons for the large difference of incidence between western and eastern countries.

    2016-09-01

    Breast cancer is the most common malignant tumor in females around the world, representing 25.2% of all cancers in women. About 1.7 million women were diagnosed with breast cancer worldwide in 2012 with a death rate of about 522,0001,2. The most frequently used methods in breast cancer screening are imaging methods, i.e. ultrasonography and mammography. A common feature of these methods is that they inherently involve the use of expensive and advanced equipment. The development of advanced computer systems allowed for the continuation of research started already in the 1980s3 and the use of contact thermography in breast cancer screening. The physiological basis for the application of thermography in medical imaging diagnostics is the so-called dermothermal effect related to higher metabolism rate around focal neoplastic lesion. This phenomenon can occur on breast surface as localized temperature anomalies4. The device developed by Braster is composed of a detector that works on the basis of thermotropic liquid crystals, image acquisition device and a computer system for image data processing and analysis. Production of the liquid crystal detector was based on a proprietary CLCF technology (Continuous Liquid Crystal Film). In 2014 Braster started feasibility study to prove that there is a potential for artificial intelligence in early breast cancer detection using Braster's proprietary technology. The aim of this study was to develop a computer system, using a client-server architecture, to an automatic interpretation of thermographic pictures created by the Braster devices.

    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.

    To filtrate breast cancer resistance protein (BCRP)-mediated resistant agents and to investigate clinical relationship between BCRP expression and drug resistance. Methods MTT assay was performed to filtrate BCRP-mediated resistant agents with BCRP expression cell model and to detect chemosensitivity of breast cancer tissue specimens to these agents. A high performance liquid chromatography (HPLC) assay was established, and was used to measure the relative dose of intracellular retention resistant agents. RT-PCR and immununohistochemistry (IHC) were employed to investigate the BCRP expression in breast cancer tissue specimens. Results MTT assay showed that the expression of BCRP increased with the increasing resistance of 5-fluorouracil (5-Fu) (P=0.8124, P<0.01). Condusion Resistance to 5-Fu can be mediated by BCRP. Clinical chemotherapy for breast cancer patients can be optimized based on BCRP-positive expression.

    Atoosa Adibi

    2015-01-01

    Full Text Available Background: Patients with the previous history of breast cancer are in risk of contralateral breast cancer. On the other hand, increased breast density is a risk factor for breast cancer and the sensitivity of detecting nonpalpable cancers in screening mammography in radiographically dense breasts is low. The use of ultrasonography in dense breast remains a controversial topic. The purpose of this study was to assess the usefulness of routine ultrasonography in follow-up of women with the previous history of breast cancer and negative mammography but dense breasts. Materials and Methods: In a cross-sectional study, a total of 267 individuals with unilateral postmastectomy mammogram screened and 153 subjects assigned to study. There were 28 subjects with American College of Radiology (ACR breast density 2 and 125 with ACR breast density 3-4, which there was no new finding in their mammogram in comparison to previous studies. We assumed subjects with ACR breast density 3-4 as mammographic Breast Imaging Reporting and Data System (BI-RADS category 0 for malignancy. Standard two-view mammogram was performed for all participants, and breast ultrasound (US examinations were performed by an expert radiologist in radial and anti-radial planes. The data were analyzed using SPSS version 20.0 (SPSS Inc., Chicago, Illinois, USA. Results: The results showed that in subjects with ACR breast density 3-4, when there was no new density in two consecutive mammograms in comparison to previous studies, US also showed no possibility for malignancy (BI-RADS 1-2. And also in subjects with ACR breast density 2, when the mammographic results were BI-RADS 1-2, the US results was the same. Conclusion: Our data indicate that for the detection of breast cancer, sensitivity of US was not greater than mammography in patients with postmastectomy unilateral dense breast if there is not any new density.

    Women who develop bilateral breast cancer at an early age are likely to harbour germline mutations in breast cancer susceptibility genes. The aim of this study was to test for concordant genetic changes in left and right breast cancer of young women (age < 50) with bilateral breast cancer that may suggest an inherited breast cancer predisposition. Microsatellite markers were used to test for loss of heterozygosity (LOH) in left and right tumours for 31 women with premenopausal bilateral breast cancer. Markers adjacent to or within candidate genes on 17p (p53), 17q (BRCA1), 13q (BRCA2), 11q (Ataxia Telangiectasia-ATM) and 3p (FHIT) were chosen. Mutational testing for BRCA1 and BRCA2 was performed for cases where blood was available. Concordant LOH in both left and right tumours was demonstrated for at least one of the markers tested in 16/31(54%) cases. Where allelic loss was demonstrated for both left and right breast cancer, the same allele was lost on each occasion. This may suggest a common mutational event. Four cases showed concordant loss of alleles in both left and right breast cancer at D17S791 (BRCA1). BRCA1 mutations were identified in two of these cases where blood was available. Four cases showed concordant LOH at D13S155 (BRCA2). Concordant LOH was further demonstrated in seven cases for D11S1778 (ATM) and four cases for D3S1300 (which maps to the FHIT gene), suggesting a possible role for these tumour suppressor genes in this subgroup of breast cancer patients. No concordant allelic loss was demonstrated for D17S786 suggesting that germline mutations in p53 are unlikely in such cases of bilateral breast cancer.

    Objective The aim of the study was to investigate the inhibitory ef ects of dendritic cel s (DCs) loaded with resistant breast cancer antigens on breast cancer in nude mice. Methods A single-cel suspension was prepared from a primary breast cancer and chemotherapeutic drugs were screened using the ATP-PCA susceptibility testing system. Cancer cel s were treated with 1/10 × IC50, 1/5 × IC50, 1/2 × IC50, 1 × IC50, and 2 × IC50 medium until their growth became steady in the 2 × IC50 medium. Peripheral blood mononuclear cel s (PBMCs) were obtained from the peripheral blood of patients with leukapheresis. The obtained adherent cel s were induced by granulocyte-macrophage colony-stimu-lating factor (GM-CSF) and interleukin-4 (IL-4) to generate DCs, which carried resistant strain cel lysis compounds or non-treated cancer cel lysis compounds. The former mature DCs carried resistant breast tumor antigens. A breast tumor-bearing nude mouse model was established with these resistant strains and the mice were randomly divided in three groups. The mice in the treatment group were injected with DCs loaded with resistant breast cancer antigens. The control group consisted of mice injected with DCs loaded with primary tumor cel antigens and the blank group consisted of mice injected with the same volume of normal saline. Changes in the cancers were observed. Results After treatment with the ef ector cel s, the cancer volume and weight were significantly dif erent to those before treatment in every group of mice (P Conclusion DCs loaded with resistant breast cancer antigens demonstrated a significant inhibition ef ect on the cancers of breast tumor-bearing nude mice.

    Optimizing the treatment of breast cancer remains a major topic of interest. In current clinical practice, breast-conserving therapy is the standard of care for patients with localized breast cancer. Technological developments have fueled interest in less invasive breast cancer treatment. Magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) is a completely noninvasive ablation technique. Focused beams of ultrasound are used for ablation of the target lesion without disrupting the skin and subcutaneous tissues in the beam path. MRI is an excellent imaging method for tumor targeting, treatment monitoring, and evaluation of treatment results. The combination of HIFU and MR imaging offers an opportunity for image-guided ablation of breast cancer. Previous studies of MR-HIFU in breast cancer patients reported a limited efficacy, which hampered the clinical translation of this technique. These prior studies were performed without an MR-HIFU system specifically developed for breast cancer treatment. In this article, a novel and dedicated MR-HIFU breast platform is presented. This system has been designed for safe and effective MR-HIFU ablation of breast cancer. Furthermore, both clinical and technical challenges are discussed, which have to be solved before MR-HIFU ablation of breast cancer can be implemented in routine clinical practice.

    Background Breast cancer is one of the most common cancers diagnosed during pregnancy. Pregnancy-associated breast cancer (PABC) is defined as breast cancer diagnosed during pregnancy or within 12 months of delivery. Nowadays PABC can be safely diagnosed, staged, and treated during pregnancy with good outcomes for both the mother and the fetus. Recent studies suggest that prognosis of women diagnosed during postpartum seems to be worse. In order to gain a better understanding of the PABC, we reviewed our centre’s experience. Patients and methods We assessed the clinicopathological parameters, evolution, and outcome of patients treated in the Fundación Instituto Valenciano de Oncología of Valencia, Spain, from October 1990 to October 2013, and compared the results of patients diagnosed during pregnancy (group ‘A’) and patients diagnosed within one year of delivery (group ‘B’). Of 12,000 cases of breast cancer registered in our database, 35 cases of PABC were identified. We included 11 patients in group ‘A’ and 24 in group ‘B’. Results In our group the median age was 35 years (range 29–42), of which ten (28%) patients had family history (first grade) of breast cancer, four patients were BRCA 1 mutation carriers. Axillary node compromise was found in 19 patients (53.5%), 24 patients were stage II or III at diagnosis (68.5%), 22 (62.8%) were ER positive, and nine (25.7%) were HER-2 positive. In group A (n = 11), five patients diagnosed before 18th week decided that a therapeutic abortion be performed before treatment, two patients were treated during pregnancy, one with chemotherapy without treatment associated complications during delivery. Four women diagnosed after 28th week decided to delay the treatment until delivery. After a follow up of 172 months, the relapse free survival (RFS) was 69% at five years and 45% at ten years. Overall survival (OS) at five years was 90.8% and 74.2% at ten years for all patients. For group ‘A’ OS was higher

    There is substantial evidence that many cancers, including breast cancer, are driven by a population of cells that display stem cell properties. These cells, termed cancer stem cells (CSCs) or tumor initiating cells, not only drive tumor initiation and growth but also mediate tumor metastasis and therapeutic resistance. In this chapter, we summarize current advances in CSC research with a major focus on breast CSCs (BCSCs). We review the prevailing methods to isolate and characterize BCSCs and recent evidence documenting their cellular origins and phenotypic plasticity that enables them to transition between mesenchymal and epithelial-like states. We describe in vitro and clinical evidence that these cells mediate metastasis and treatment resistance in breast cancer, the development of novel strategies to isolate circulating tumor cells (CTCs) that contain CSCs and the use of patient-derived xenograft (PDX) models in preclinical breast cancer research. Lastly, we highlight several signaling pathways that regulate BCSC self-renewal and describe clinical implications of targeting these cells for breast cancer treatment. The development of strategies to effectively target BCSCs has the potential to significantly improve the outcomes for patients with breast cancer.

  9. Breast cancer and breast screening: perceptions of Chinese migrant women living in New Zealand

    Full Text Available INTRODUCTION: Migrant Chinese constitute a significant and increasing proportion of New Zealand women. They have lower rates of participation in breast cancer screening than other New Zealanders, but reasons for this are unknown. The aim of this study was to investigate factors affecting Chinese women’s understanding of, and access to, breast health services, to better understand reasons for low participation in screening and their experiences of breast cancer clinic care. METHODS: The participants were 26 Chinese migrant women—19 recruited in the community and seven recruited from 17 eligible women attending a breast clinic between 2008 and 2010 in Wellington, New Zealand. The design was that of a qualitative study, using semi-structured interviews and thematic content analysis. FINDINGS: There were low levels of awareness about the national breast screening programme and limited engagement with preventive primary care services. Concerns about privacy and a range of communication difficulties were identified that related to oral language, lack of written information in Chinese, and limited understanding about Chinese perceptions of ill health and traditional Chinese medicine by New Zealand health professionals. CONCLUSION: Addressing communication barriers for Chinese migrant women has the potential to raise awareness about breast cancer and breast health, and to increase successful participation in breast cancer screening. Greater efforts are needed to ensure this group has an understanding of, and is engaged with a primary care provider. Such efforts are key to improving health for this growing sector of the New Zealand population.

    Male breast cancer (male BC) accounts for Klinefelter syndrome) and a positive family history for breast cancer. About 90% of male BC are invasive ductal carcinomas. Standard treatment for localized cancer is surgical removal. Adjuvant radiation and systemic therapy are the same as in women with breast cancer. Male BC expresses hormone receptors in about 90% of cases; therefore, tamoxifen is a therapeutic option. A future challenge for the urologist or andrologist is to diagnose the disease at an early stage to improve prognosis.

    It was the object of this round table to discuss the different techniques for treatment of breast cancer by radiation only, in order to seek out their common points. Six French Centres participated: the Foundation Curie (Paris), the Centre Anti-Cancéreux de l'Hôpital Sainte-Marguerite (Marseille), the Service de Radiologie de l'Hôpital Civil (Strasbourg), the Centre René-Huguenin (Saint-Cloud)k, the Service de Carcinologie Radiothérapique de l'Hôpital Henri-Mondor (Créteil) and the Institut Gustave-Roussy (Villejuif). Our readers can see the details of the treatments practiced by each of the six schools in their own particular techniques, in the following pages. We will confine ourselves here to a brief summary only. It should be recalled that these techniques for treatment of breast cancer by radiotherapy alone vere developed almost simultaneously in several different Centres around 1960, as a result of the revolution in radiotherapy which began in 1975 with the installation of tele-Cobalt...

    The prevalence of breast cancer in Venezuela is particularly alarming, which is attributed to healthcare inequalities, low health literacy, and lagging compliance with prevention methods (i.e., screening and mammography). While the right to health is acknowledged by the Venezuelan constitution, activism beyond governmental confines is required to increase women's breast cancer awareness and decrease mortality rates. Through the development of social support and strategic communicative methods enacted by healthcare providers, it may be possible to empower women with the tools necessary for breast cancer prevention. This paper discusses issues surrounding women's breast cancer, such as awareness of the disease and its risks, self-advocacy, and the roles of activists, healthcare providers, and society. Specifically, it describes a four-year action-oriented research project developed in Venezuela, which was a collaborative work among researchers, practitioners, NGOs, patients, journalists, and policymakers. The outcomes include higher levels of awareness and interest among community members and organizations to learn and seek more information about women's breast cancer, better understandings of the communicated messages, more media coverage and medical consultations, increasing positive patient treatments, expansion of networking of NGOs, as well as a widely supported declaration for a national response against breast cancer in Venezuela.

    Full Text Available Background. Nearly 70% of women diagnosed with breast cancer in Ghana are in advanced stages of the disease due especially to low awareness, resulting in limited treatment success and high death rate. With limited epidemiological studies on breast cancer in Ghana, the aim of this study is to assess and understand the pattern of breast cancer distribution for enhancing early detection and treatment. Methods. We randomly selected and screened 3000 women for clinical palpable breast lumps and used univariate and bivariate analysis for description and exploration of variables, respectively, in relation to incidence of breast cancer. Results. We diagnosed 23 (0.76% breast cancer cases out of 194 (6.46% participants with clinically palpable breast lumps. Seventeen out of these 23 (0.56% were premenopausal (<46.6 years with 7 (0.23% being below 35 years. With an overall breast cancer incidence of 0.76% in this study, our observation that about 30% of these cancer cases were below 35 years may indicate a relative possible shift of cancer burden to women in their early thirties in Ghana, compared to Western countries. Conclusion. These results suggest an age adjustment for breast cancer screening to early twenties for Ghanaian women and the need for a nationwide breast cancer screening to understand completely the pattern of breast cancer distribution in Ghana.

    Objective:To explore the relationship of overexpression of epidermal growth factor receptor(EGFR)in occurrence,development and treatment of breast cancer. Methods:Samples of 46 breast adenoma tissues and 86 breast cancer tissues were regularly dehydrate-fixed,embedded in paraffin,sliced in to 5 μm thick,stained with SABC immunohistochemistry and coloured with DAB. Results:The positive staining of EGFR was shown as brown- yellow and distributed in cytoplasm.The positive rates in the tissues of breast adenosis and breast cancer were 17.04%(6/46)and 56.98%(49/86)respectively.The positive rates of EGFR in the tissue of invasive ductal carcinoma was 64.49%(41/59),which was significantly higher than that in in situ carcinoma(P<0.05).The positive rate of lymph metastasis group was higher than that in non-lymph metastasis group (P<0.05). Conclusion:The overexpression of EGFR was related with occurrence,lymph metastasis and pathologic types of breast cancer.The examination of EGFR in the breast cancer can serve as a guidance for target chemotherapy.

  17. 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.

    Full Text Available Abstract Background Previous studies demonstrated breast cancer tumor tissue samples could be classified into different subtypes based upon DNA microarray profiles. The most recent study presented evidence for the existence of five different subtypes: normal breast-like, basal, luminal A, luminal B, and ERBB2+. Results Based upon the analysis of 599 microarrays (five separate cDNA microarray datasets using a novel approach, we present evidence in support of the most consistently identifiable subtypes of breast cancer tumor tissue microarrays being: ESR1+/ERBB2-, ESR1-/ERBB2-, and ERBB2+ (collectively called the ESR1/ERBB2 subtypes. We validate all three subtypes statistically and show the subtype to which a sample belongs is a significant predictor of overall survival and distant-metastasis free probability. Conclusion As a consequence of the statistical validation procedure we have a set of centroids which can be applied to any microarray (indexed by UniGene Cluster ID to classify it to one of the ESR1/ERBB2 subtypes. Moreover, the method used to define the ESR1/ERBB2 subtypes is not specific to the disease. The method can be used to identify subtypes in any disease for which there are at least two independent microarray datasets of disease samples.

    Full Text Available "nBreast cancer is the most common cancer occurring among women. The mortality rate of breast cancer can be reduced by regular breast cancer screening program. This study was carried out to identify the knowledge and practice of women about breast cancer screening in Zahedan, southeast of Iran. In this cross- sectional study, 384 women were selected as an improbability sample of women referring to Qouds maternity hospital. Knowledge and practice of them about breast cancer screening were investigated through face-to-face interview based on a purposed questionnaire, and data were analyzed using descriptive and analytical statistics. Only 8.3% of women were aware of breast cancer screening methods. About breast self-examination 21.6%, and about mammography 3.4% had good knowledge. Overall knowledge of breast cancer screening was insufficient in 67.4%. There was statistically significant relationship between knowledge of breast cancer screening and level of education, history of individual breast disease, and history of breast cancer in their families (P < 0.001. There was statistically significant and inverse relationship between knowledge of how to examine the breasts and knowledge about mammography with age (P < 0.001. Practices of women in Zahedan about Breast cancer screening were very low. Only 4.5% of women performed breast self examination (BSE, on a regular basis, 4.1% had ever had a clinical breast examination (CBE, and %1.3 had a mammography throughout their life. Our findings suggest that knowledge and practice about breast cancer screening was relatively in a weak level and it needs to be improved.

    Ziv, Elad; Tice, Jeffrey A.; Sprague, Brian; Vachon, Celine M.; Cummings, Steven R.; Kerlikowske, Karla

    2017-01-01

    Background Breast cancer can be prevented with selective estrogen receptor modifiers (SERMs) and aromatase inhibitors (AIs). The US Preventive Services Task Force recommends that women with a 5-year breast cancer risk ≥3% consider chemoprevention for breast cancer. More than 70 single nucleotide polymorphisms (SNPs) have been associated with breast cancer. We sought to determine how to best integrate risk information from SNPs with other risk factors to risk stratify women for chemoprevention. Methods We used the risk distribution among women ages 35–69 estimated by the Breast Cancer Surveillance Consortium (BCSC) risk model. We modeled the effect of adding 70 SNPs to the BCSC model and examined how this would affect how many women are reclassified above and below the threshold for chemoprevention. Results We found that most of the benefit of SNP testing a population is achieved by testing a modest fraction of the population. For example, if women with a 5-year BCSC risk of >2.0% are tested (~21% of all women), ~75% of the benefit of testing all women (shifting women above or below 3% 5-year risk) would be derived. If women with a 5-year risk of >1.5% are tested (~36% of all women), ~90% of the benefit of testing all women would be derived. Conclusion SNP testing is effective for reclassification of women for chemoprevention, but is unlikely to reclassify women with <1.5% 5-year risk. These results can be used to implement an efficient two-step testing approach to identify high risk women who may benefit from chemoprevention. PMID:28107349

    Full Text Available Reconstructive surgery for breast cancer are an integral method of rehabilitation of cancer patients. Breast reconstruction may be delayed and instantaneous. The article presents a description of the thoraco-epigastric flap for breast reconstruction in cancer. The operation involves the replacement of the remote volume (after radical resection of the breast and the breast skin adjacent tissues adjacent to the inframammary crease from the side of the anterior abdominal wall. Surgery is indicated when the tumor in the lower parts of the breast, closest to the skin, in combination with small size breast cancer. The article presents a clinical example of this operation. Described in detail the operation, received a good cosmetic result. The advantage of the application of thoraco-epigastric flap is in the simplicity of the technique of its execution, good blood supply, donor wound is easily sutured due to the possible wide separating cellular adjacent skin and subcutaneous tissue. The disadvantage of this method is limited and the need for careful monitoring of perforating branches of the upper epigastric artery. Thus, thoraco-epigastric flap, can be applicable when performing reconstructive operations for breast cancer in compliance with the necessary requirements for the formation of the flap and the correct attitude to feeding the flap vessels, and virtually eliminates possible complications with the healing of the flap. Undoubtedly, reconstructive plastic surgery for breast cancer, during the testimony and technical capabilities, are an essential component of surgical treatment.

    Full Text Available Introduction: Breast cancer is the most common cancer in women, and if diagnosed on time, the chance of treatment will increase. There is limited information about the knowledge and practice of Iranian women about early detection of breast cancer and in this study we aimed to investigate it in Kerman. Methods: This was a cross-sectional study done on 120 women; from 6 randomly selected maternal and childcare centers spread around Kerman, women were questioned about the primary signs of breast cancer and the screening methods. Results: The results show that 70% of women thought that with on time detection, breast cancer can be successfully treated, but 47% had no idea about any screening method. The most common breast cancer sign mentioned by women was a painless lump. Breast self examination as the easiest and cheapest screening method was never done in 51% of women. The most common reason for not performing screening tests in the participants, was not knowing anything about it. Conclusion: Although breast cancer when diagnosed on time is treatable, the knowledge and attitude of Iranian women about breast cancer screening and the signs of breast cancer are very low. Educational programs to increase women's knowledge about breast cancer should be foreseen and performed

    Full Text Available Objective: to assess the knowledge of blind women about the risk factors for breast cancer and whether they look for early detection of this cancer. Methods: a quasi-experimental study with 72 blind women distributed in focus groups. Data were collected through interviews. Results: few participants had knowledge about one or more risk factors for breast cancer, but most practiced early detection. Health education was developed using breast kits and demonstration of breast self-examination. It was obtained qualitative improvement of knowledge of the participants about breast cancer, its risk factors and early detection practices. In addition, participants demonstrated breast self-examination confidently. Conclusion: we need to develop in a harder manner educational activities to clarify about breast cancer risk factors and the importance of periodically carrying out breast self-examination, clinical examination and mammography.

    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.

    The active form of vitamin D, in conjunction with his own receptor, affect a multitude of biological processes in the cell (inter alia it influences the expression of oncogenes and tumor suppressor genes). There is an increasing volume of scientific publications examining the relationships between serum vitamin D levels, vitamin D supplementation and malignant diseases. Some articles suggest inverse relationship between the low serum levels of vitamin D and the breast cancer risk and mortality, whilst other publications do not support this view. Thus the present opinion is conflicted. Vitamin D can exert a beneficial influence on the symptoms and outcomes of a large number of ailments, but its role in affecting cancer is still not completely clear.

    Isard, H J

    1976-11-01

    The hallmark of the normal breast thermogram is relative symmetry of vascular configuration and thermal content with preservation of the breast contour. Accepted criteria of abnormality are predicated upon graphic and thermal asymmetry with emphasis placed upon elevated temperature, an increase in the number of discernible vessels, and distorted vascular patterns. The association of a confirmed breast cancer and an avascular thermogram has been labeled a false negative. Avascularity ("cold" breast), particularly in the lower half, with normal vessels in the same location of the opposite breast is suggested as an additional characteristic of abnormality. Illustrative cases are presented.

Supplemental breast MRI is sometimes used in addition to mammography despite the lack of clinical evidence for it. Breast imaging after cancer treatment is an emotionally charged experience, an important part of survivorship care, and a topic about which limited patient information exists. We assessed women’s experiences and preferences about breast cancer surveillance imaging with the goal of determining where gaps in care and knowledge could be filled. Participants and methods: We conducted six focus groups with a convenience sample of 41 women in California, North Carolina, and New Hampshire (USA. Participants were aged 38–75 years, had experienced stage 0–III breast cancer within the previous 5 years, and had completed initial treatment. We used inductive thematic analysis to identify key themes from verbatim transcripts. Results: Women reported various types and frequencies of surveillance imaging and a range of surveillance imaging

    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.

    The adjuvant therapy of postmenopausal, hormonereceptor positive breast cancer patients with aromatase inhibitors in ATAC, ABCSG 8/ ARNO 95 and IES trial revealed just a benefit in terms of disease-free survival, but not for over-all survival. Thus MA-17 trial is so far the only study which could demonstrate a survival benefit for node positive disease by "extended adjuvant" therapy with letrozole. Node- and receptorpositive, postmenopausal women show a higher benefit by anthracycline containing chemotherapy in combination with tamoxifen, than by endocrine therapy alone. But tamoxifen should given sequentially to chemotherapy (Intergroup 0100/ SWOG-8814 trial). Adjuvant chemotherapy with three cycles FEC followed by three cycles docetaxel reveals a survival benefit compared to six cycles FEC, especially in women older than 50 years (PACS 01 trial). Furthermore there is evolving evidence that dose-dense, interval shortened chemotherapy is superior to standard chemotherapy in adjuvant setting. The impaired survival of receptornegative, nodalpositive breast cancer patients seems to be converted to a survival improvement compared with receptorpositive patients by modern adjuvant cytotoxic regimens (metaanalysis CALGB 8541, 9344, 9741). In primary systemic chemotherapy survival is strongly associated with the rate of pathohistological complete remissions (NSABP B-27). The combination of cytotoxic drugs has no further influence on survival, but the sequential administration of taxane increases the rate of pCR. A difference in survival stratified by pCR and non-pCR in breast and positive nodal status could not be detected, so that the number of involved lymph nodes seems to be the strongest prognostic factor and is independent of tumor response in the breast. The sentinel node biopsy is a safe and reliable method, but the rate of false negative findings depends on the pathohistological methods (NSABP B-32). The morbidity of this method is low compared with conventional

    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.

    Full Text Available OBJECTIVE To analyze cervical and breast cancer mortality in Brazil according to socioeconomic and welfare indicators. METHODS Data on breast and cervical cancer mortality covering a 30-year period (1980-2010 were analyzed. The data were obtained from the National Mortality Database, population data from the Brazilian Institute of Geography and Statistics database, and socioeconomic and welfare information from the Institute of Applied Economic Research. Moving averages were calculated, disaggregated by capital city and municipality. The annual percent change in mortality rates was estimated by segmented linear regression using the joinpoint method. Pearson’s correlation coefficients were conducted between average mortality rate at the end of the three-year period and selected indicators in the state capital and each Brazilian state. RESULTS There was a decline in cervical cancer mortality rates throughout the period studied, except in municipalities outside of the capitals in the North and Northeast. There was a decrease in breast cancer mortality in the capitals from the end of the 1990s onwards. Favorable socioeconomic indicators were inversely correlated with cervical cancer mortality. A strong direct correlation was found with favorable indicators and an inverse correlation with fertility rate and breast cancer mortality in inner cities. CONCLUSIONS There is an ongoing dynamic process of increased risk of cervical and breast cancer and attenuation of mortality because of increased, albeit unequal, access to and provision of screening, diagnosis and treatment.

    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

    The increased use of mammography and introduction of breast screening programmes have resulted in a rise in clinically-occult breast cancer, with one-third of all breast carcinomata diagnosed being non-palpable. These types of cancer have a unique natural history and biology compared to symptomatic breast cancer and this needs to be taken into account when considering surgery and adjuvant treatment. The majority of studies demonstrating efficacy of adjuvant treatments are largely based on patients with symptomatic breast cancer. The current evidence for the role of surgery and adjuvant therapy for screen-detected breast cancer was reviewed in light of their improved prognosis, compared to symptomatic breast cancer.

    Full Text Available Purpose : Staging of breast tumor has important implications for treatment and prognosis. This study aims at pinpointing the frequency of each stage among familial and nonfamilial breast cancers. Materials and Methods : Ninety-nine Jordanian females diagnosed with familial and nonfamilial breast cancer between 2000 and 2002 were enrolled in this study All breast cancer cases were staged according to the TNM classification into in situ, early invasive, advanced invasive and metastatic. Results : Forty-three cases were familial breast cancer and 56 were nonfamilial. One female breast cancer was diagnosed with ductal carcinoma in situ (DCIS cancer. Fifty cases were diagnosed in early stages of invasive breast cancer, of which 31 cases were familial, 29 cases were classified as advanced invasive, where 21 cases were nonfamilial and 19 cases were metastatic stage of breast cancer, with 16 nonfamilial cases. Stage 2b was the most common stage of early invasive cases and represented 48% of the early stage of breast cancer. On the other hand, among cases diagnosed with advanced invasive breast cancer, stage 3a was the most common stage and represented 89.6% of the advanced stage. Interestingly, all cases of stage 3a belonged to TNM stages of T2N2M0 and T3N1M0. The tumor size in all cases of Jordanian females diagnosed with advanced invasive breast cancer exceeded 2 cm in size due to selection bias from symptomatic women in our study. Conclusion : The incidence of nonfamilial breast cancer was slightly higher than that of the familial type amongst studied the Jordanian females studied. The early invasive stage of breast cancer was more common in the familial while the advanced invasive and metastatic breast cancer cases were encountered more often in the nonfamilial type. Our study was based on a small sample and symptomatic women. Therefore, more research with larger population samples is needed to confirm this conclusion.

    In recent years, the theory of cancer stem cells has provided a new perspective on the treatment of cancers including breast cancer. The accurate sorting of breast cancer stem cells is critical. The sorting procedure is consist of 4 steps: isolation of side population, serum-free suspension culture,determination of specific cell surface markers and of the activity of aldehyde dehydrogenase 1 ( ALDH1 ) enzymatic through the ALDEFLUOR assay. Some studies choose drug resistance as an additional method for sorting cancer stem cells because of the enrichment of cancer stem cells after chemotherapy . The controversy about the sorting outcome of breast cancer stem cell mainly focus on molecular markers like CD44+ CD24- and ALDH1+ . The problem needed to be settled is to identify which sorting method and markers are appropriate.%"肿瘤干细胞"学说的提出为肿瘤包括乳腺肿瘤在内的治疗提供了新的思路.乳腺肿瘤干细胞正确的分选纯化是研究的关键,其分选主要历经侧群细胞分选、无血清悬浮培养、细胞表面分子标记分选、ALDEFLUOR试剂盒检测乙醛脱氢酶1高活性分选法4个阶段;由于化疗会富集肿瘤干细胞,部分学者把化疗耐药也作为一种分选的方法.目前有关乳腺肿瘤干细胞分选结果的争论主要集中在标志物CD44+ CD24-、ALDH1+ 之间.哪种分选方法或标志物的选择更适宜分选乳腺肿瘤干细胞成为亟待解决的问题.

    The aetiology of breast cancer is multifactorial. While there are known genetic predispositions to the disease it is probable that environmental factors are also involved. Recent research has demonstrated a regionally specific distribution of aluminium in breast tissue mastectomies while other work has suggested mechanisms whereby breast tissue aluminium might contribute towards the aetiology of breast cancer. We have looked to develop microwave digestion combined with a new form of graphite furnace atomic absorption spectrometry as a precise, accurate and reproducible method for the measurement of aluminium in breast tissue biopsies. We have used this method to test the thesis that there is a regional distribution of aluminium across the breast in women with breast cancer. Microwave digestion of whole breast tissue samples resulted in clear homogenous digests perfectly suitable for the determination of aluminium by graphite furnace atomic absorption spectrometry. The instrument detection limit for the method was 0.48 μg/L. Method blanks were used to estimate background levels of contamination of 14.80 μg/L. The mean concentration of aluminium across all tissues was 0.39 μg Al/g tissue dry wt. There were no statistically significant regionally specific differences in the content of aluminium. We have developed a robust method for the precise and accurate measurement of aluminium in human breast tissue. There are very few such data currently available in the scientific literature and they will add substantially to our understanding of any putative role of aluminium in breast cancer. While we did not observe any statistically significant differences in aluminium content across the breast it has to be emphasised that herein we measured whole breast tissue and not defatted tissue where such a distribution was previously noted. We are very confident that the method developed herein could now be used to provide accurate and reproducible data on the aluminium content

    Full Text Available Abstract Background Breast cancer is the leading cause of cancer mortality among Jordanian women. Breast malignancies are detected at late stages as a result of deferred breast health-seeking behaviour. The aim of this study was to explore Jordanian women’s views and perceptions about breast cancer and breast health. Methods We performed an explorative qualitative study with purposive sampling. Ten focus groups were conducted consisting of 64 women (aged 20 to 65 years with no previous history and no symptoms of breast cancer from four governorates in Jordan. The transcribed data was analysed using latent content analysis. Results Three themes were constructed from the group discussions: a Ambivalence in prioritizing own health; b Feeling fear of breast cancer; and c Feeling safe from breast cancer. The first theme was seen in women’s prioritizing children and family needs and in their experiencing family and social support towards seeking breast health care. The second theme was building on women’s perception of breast cancer as an incurable disease associated with suffering and death, their fear of the risk of diminished femininity, husband’s rejection and social stigmatization, adding to their apprehensions about breast health examinations. The third theme emerged from the women’s perceiving themselves as not being in the risk zone for breast cancer and in their accepting breast cancer as a test from God. In contrast, women also experienced comfort in acquiring breast health knowledge that soothed their fears and motivated them to seek early detection examinations. Conclusions Women’s ambivalence in prioritizing their own health and feelings of fear and safety could be better addressed by designing breast health interventions that emphasize the good prognosis for breast cancer when detected early, involve breast cancer survivors in breast health awareness campaigns and catalyse family support to encourage women to seek breast

    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.

    The relation of breast cancer to diazepam use was evaluated in a case-control study of 1236 women with breast cancer and 728 control subjects with other malignancies. Compared to women who never used diazepam, the relative risk for women who used the drug at least 4 days per week for at least 6 months was estimated to be 0.9, with 95% confidence limits of 0.5 and 1.6. There was no apparent association for recent use, or for use in the distant past, although confidence intervals were fairly wide in these categories. The results were not explained by various potential confounding factors, including the major risk factors for breast cancer. The findings suggest that regular diazepam use does not increase the risk of breast cancer relative to other cancers.

    Objective: To explore the effect of different anesthesia and analgesia methods on the T lymphocyte subsets, cytokines and the levels of the stress hormone in patients with breast cancer surgery.Methods: 86 cases of breast cancer were divided into two groups by random digits table, control group of 43 cases with total intravenous anesthesia, and the observation group of 43 cases with total intravenous anesthesia combined with epidural anesthesia and postoperative underwent analgesia. The T lymphocyte subsets, cytokines and the levels of the stress hormone were detected before and after operation and compared. Results:CD3+, CD4+ and CD4+/CD8+ of the two groups at T1 or T2 were significantly lower than those at T0, and those in the observation group were significantly lower than the control group, and the difference between the two groups has statistical significance. IL-6, CRP and TNF-α levels of the two groups at T1, T2 or T3 were significantly higher than those at T0, and those in the observation group were significantly lower than the control group, and the difference between the two groups has statistical significance. Each index of two groups at T4 were restored to T0, and the differences were no statistically significant. The cortisol levels of two groups at T1 or T2 were significantly increased compared with T0, and the increase in the observation group was less than that of the control group, the difference between the two groups has statistical significance. The cortisol levels of two groups at T4 were restored to T0, and the differences were no statistically significant.Conclusion:Epidural analgesia after the intravenous anesthesia combined with epidural anesthesia for breast cancer cure patients has lighter immunosuppression and stress reaction, has less influence on inflammatory factors, is an ideal anesthesia and analgesia.

    Raman spectroscopy and infrared (IR) spectroscopy are both techniques that allow for the investigation of vibrating chemical particles. These techniques provide information not only about chemical particles through the identification of functional groups and spectral analysis of so-called "fingerprints", these methods allow for the qualitative and quantitative analyses of chemical substances in the sample. Both of these spectral techniques are frequently being used in biology and medicine in diagnosing illnesses and monitoring methods of therapy. The type of breast cancer found in woman is often a malignant tumor, causing 1.38 million new cases of breast cancer and 458 000 deaths in the world in 2013. The most important risk factors for breast cancer development are: sex, age, family history, specific benign breast conditions in the breast, ionizing radiation, and lifestyle. The main purpose of breast cancer screening tests is to establish early diagnostics and to apply proper treatment. Diagnoses of breast cancer are based on: (1) physical techniques (e.g., ultrasonography, mammography, elastography, magnetic resonance, positron emission tomography [PET]); (2) histopathological techniques; (3) biological techniques; and (4) optical techniques (e.g., photo acoustic imaging, fluorescence tomography). However, none of these techniques provides unique or especially revealing answers. The aim of our study is comparative spectroscopic measurements on patients with the following: normal non-cancerous breast tissue; breast cancer tissues before chemotherapy; breast cancer tissues after chemotherapy; and normal breast tissues received around the cancerous breast region. Spectra collected from breast cancer patients shows changes in amounts of carotenoids and fats. We also observed changes in carbohydrate and protein levels (e.g., lack of amino acids, changes in the concentration of amino acids, structural changes) in comparison with normal breast tissues.

    Objective: To investigate the effect of breast-conservation therapy in early stage breast cancer. Methods: A total of 234 early stage breast carcinoma patients received breast conserving treatment in our hospital. After the operation, they underwent adjuvant chemotherapy and radiotherapy. All of these patients desired to preserve their breasts. Results: After median follow-up of 29.46 months (range from 3 to 100 months), 3 cases had local relapse and 8 cases had distant metastasis. The overall survival rate of 5 year was 96.7%, and the disease free survival rate of 5 year was 87.85%. Conclusion: For early stage breast carcinoma patients, classic quadrantectomy, axillary dissection and post-operative adjuvant chemotherapy and radiotherapy lead to excellent local control and good survival.

    Worldwide, breast cancer is the most frequently diagnosed life-threatening cancer in women and the most important cause of cancer-related deaths among women. This disease is on the rise in Turkey. Metabolic syndrome is a cluster of metabolic disturbances including insulin resistance, dyslipidemia, hypertension, abdominal obesity and high blood sugar. Several studies have examined the association of the individual components of the metabolic syndrome with breast cancer. More recent studies have shown it to be an independent risk factor for breast cancer. It has also been associated with poorer prognosis, increased incidence, a more aggressive tumor phenotype. Basic research studies are now in progress to illuminate the molecular pathways and mechanisms that are behind this correlation. Given the fact that all of the components of metabolic syndrome are modifiable risk factors, preventive measures must be established to improve the outcome of breast cancer patients. In this review we set the background by taking into account previous studies which have identified the components of metabolic syndrome individually as breast cancer risk factors. Then we present the latest findings which elaborate possible explanations regarding how metabolic syndrome as a single entity may affect breast cancer risk.

    2015-01-01

    Women living with a diagnosis of breast cancer constitute more than 20 % of the cancer survivor population in the United States. Research on trajectories of psychological adjustment in women recently diagnosed with breast suggests that the largest proportion of women evidences relatively low psychological distress either from the point of diagnosis or after a period of recovery. Substantial heterogeneity exists, however, and some women are at risk for lingering depression, anxiety, fear of cancer recurrence and other long-term psychological effects. Most women diagnosed with breast cancer also report a number of benefits that arise from their experience of cancer. Longitudinal studies have illuminated risk and protective factors for psychological adjustment in breast cancer survivors, which we describe in this chapter. Effective psychosocial interventions, as evidenced in randomized controlled trials, also are available for bolstering breast cancer-related adjustment. We offer directions for research to deepen the understanding of biological, psychological, and social contributors to positive adjustment in the context of breast cancer, as well as suggestions for the development of optimally efficient evidence-based psychosocial interventions for women living with the disease.

    Hereditary breast cancer accounts for about 10% of all breast cancers and BRCA1 and BRCA2 genes have been identified as validated susceptibility genes for this pathology. Testing for BRCA gene mutations is usually based on a pre-screening approach, such as the partial denaturation DHPLC method, and capillary direct sequencing. However, this approach is time consuming due to the large size of BRCA1 and BRCA2 genes. Recently, a new low cost and time saving DHPLC protocol has been developed to analyze gene mutations by using SURVEYOR(®) Nuclease digestion and DHPLC analysis. A subset of 90 patients, enrolled in the Genetic Counseling Program of the National Cancer Centre of Bari (Italy), was performed to validate this approach. Previous retrospective analysis showed that 9/90 patients (10%) were mutated in BRCA1 and BRCA2 genes and these data were confirmed by the present approach. DNA samples underwent touchdown PCR and, subsequently, SURVEYOR(®) nuclease digestion. BRCA1 and BRCA2 amplicons were divided into groups depending on amplicon size to allow multiamplicon digestion. The product of this reaction were analyzed on Transgenomic WAVE Nucleic Acid High Sensitivity Fragment Analysis System. The operator who performed the DHPLC surveyor approach did not know the sequencing results at that time. The SURVEYOR(®) Nuclease DHPLC approach was able to detect all alterations with a sensitivity of 95%. Furthermore, in order to save time and reagents, a multiamplicon setting preparation was validated.

    Although the concept of aerobic glycolysis in cancer was already reported in the 1930s by Otto Warburg, the understanding of metabolic pathways remains challenging especially due to the heterogeneity of cancer. In consideration of four different time points (1, 2, 4, and 7 days of incubation), GC-MS profiling of metabolites was performed on cell extracts and supernatants of breast cancer cell lines (MDA-MB-231, -453, BT-474) with different sub classification and the breast epithelial cell line MCF-10A. To the exclusion of trypsinization, direct methanolic extraction, cell scraping and cell disruption was executed to obtain central metabolites. Major differences in biochemical pathways have been observed in the breast cancer cell lines compared to the breast epithelial cell line, as well as between the breast cancer cell lines themselves. Characteristics of breast cancer subtypes could be correlated to their individual metabolic profiles. PLS-DA revealed the discrimination of breast cancer cell lines from MCF-10A based on elevated amino acid levels. The observed metabolic signatures have great potential as biomarker for breast cancer as well as an improved understanding of subtype specific phenomenons of breast cancer.

    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

    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.

    Background: An increased breast cancer incidence and poor survival have been reported for women with neurofibromatosis 1 (NF1). To explain the poor survival, we aimed to link the histopathology and clinical characteristics of NF1-associated breast cancers. Methods: The Finnish Cancer Registry and the Finnish NF Registry were cross-referenced to identify the NF1 patients with breast cancer. Archival NF1 breast cancer specimens were retrieved for histopathological typing and compared with matched controls. Results: A total of 32 breast cancers were diagnosed in 1404 NF1 patients during the follow-up. Women with NF1 had an estimated lifetime risk of 18.0% for breast cancer, and this is nearly two-fold compared with that of the general Finnish female population (9.74%). The 26 successfully retrieved archival NF1 breast tumours were more often associated with unfavourable prognostic factors, such as oestrogen and progesterone receptor negativity and HER2 amplification. However, survival was worse in the NF1 group (P=0.053) even when compared with the control group matched for age, diagnosis year, gender and oestrogen receptor status. Scrutiny of The Cancer Genome Atlas data set showed that NF1 mutations and deletions were associated with similar characteristics in the breast cancers of the general population. Conclusions: These results emphasise the role of the NF1 gene in the pathogenesis of breast cancer and a need for active follow-up for breast cancer in women with NF1. PMID:27931045

The aim of this study was to analyze the utilization of CHP among women with breast cancer in Taiwan. Methods. The usage, frequency of services, and CHP prescribed for breast cancer among women with breast cancer were evaluated, recruited from a randomly sampled cohort of 1,000,000 beneficiaries from the National Health Insurance Research Database. The logistic regression method was employed to estimate the odds ratios (ORs for utilization of CHP. Results. 81.5 percent (N=2,236 of women with breast cancer utilized traditional Chinese medicine (TCM and 18% of them sought TCM with the intent of treating their breast cancer. Jia-wei-xiao-yao-san (Augmented Rambling Powder was the most frequently prescribed formula for treating breast cancer. Among the top 10 most frequently prescribed CHP for treating breast cancer, seven contained dang qui (Angelica sinensis-radix and six contained ren shen (Panax ginseng-radix, which are reported to have potential beneficial synergistic effects on breast cancer cells. Conclusion. CHP containing dang qui (Angelica sinensis-radix or ren shen (Panax ginseng-radix are the most frequently prescribed for breast cancer and their effects should be taken into account by healthcare providers.

    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 Breast conserving surgery (BCS with following external beam radiation therapy (EBRT of the conserved breast has become widely accepted in the last decades for the treatment of early invasive breast cancer. The standard technique of EBRT after BCS is to treat the whole breast up to a total dose of 42.5 to 50 Gy. An additional dose is given to treated volume as a boost to a portion of the breast. In the early stage of breast cancer, research has shown that the area requiring radiation treatment to prevent the cancer from local recurrence is the breast tissue that surrounds the area where the initial cancer was removed. Accelerated partial breast irradiation (APBI is an approach that treats only the lumpectomy bed plus a 1-2 cm margin rather than the whole breast and as a result allows accelerated delivery of the radiation dose in four to five days. There has been a growing interest for APBI and various approaches have been developed under phase I-III clinical studies; these include multicatheter interstitial brachytherapy, balloon catheter brachytherapy, conformal external beam radiation therapy (3D-EBRT and intra-operative radiation therapy (IORT. Balloon-based brachytherapy approaches include MammoSite, Axxent electronic brachytherapy, Contura, hybrid brachytherapy devices. Another indication for breast brachytherapy is reirradiation of local recurrence after mastectomy. Published results of brachytherapy are very promising. We discuss the current status, indications, and technical aspects of breast cancer brachytherapy.

    Full Text Available Aim: To evaluate the knowledge of breast cancer and lymphoedema symptoms among mastectomy survivors. Material and methods: The research was carried out in the Centre of Oncology Branch in Cracow. The survey comprised 60 hospitalized patients as well as 30 healthy subjects from the Małopolska region. The scientific method used was a specially designed questionnaire. Results : Women with a history of cancer demonstrate a health-oriented approach. The subjects known as the experimental group perform breast self-examinations, regularly visit a gynaecologist, are aware of the most severe mastectomy complication – lymphoedema, and recognize the impact of physical activity on it. Breast cancer operation survivors have a good knowledge of breast cancer and lymphoedema, however, existing shortcomings in practical issues are worrying. On the contrary, the control group neglects regular check-ups, evaluates its own knowledge as negligible and, most surprisingly, is not interested in the subject of breast cancer and lymphoedema, even though the subjects of the group believe that arm swelling is connected to all types of breast cancer surgeries. Conclusions : Breast cancer survivors have a good knowledge of their disorder but are still lacking some essential information. Respondents from the control group have a limited knowledge in the field of cancer and lymphoedema, are not interested in breast cancer matters and are not encouraged by gynaecologists to perform breast self-examinations. Educational prevention programs should develop a health-oriented approach among all women and emphasize their basic role in therapy.

    This paper summarizes the treatment of locally advanced breast cancer, inflammatory breast cancer, and locally recurrent breast cancer. A multidisciplinary approach considering subclinical distant metastases is needed to treat these types of breast cancer. Subclinical distant metastasis is observed in about 80% of case of locally advanced cancer, and treatment of subclinical distant metastases, e.g., by endocrinotherapy and chemotherapy, is therefore essential to improving the prognosis. The standard therapy for unresectable locally advanced breast cancer consists of induction chemotherapy with anthracyclines and local treatment with mastectomy or irradiation. Previous reports have stated that induction chemotherapy was effective in 60-80% of the primary lesions or lymph node metastasis, and the CR rates were in the 10-20% range. Combination therapy with induction chemotherapy clearly improved the outcome over local treatment alone. The usual irradiation dose is 50 to 60 Gy/5 to 7 weeks to the whole breast or the thoracic wall. Boost irradiation at a dose of 10 to 25 Gy is performed in unresectable cases. The boost irradiation dose to the lymph node area is usually 45 to 50 Gy/5 to 6 weeks in cases without gross lesions and 10 to 15 Gy in cases with gross lesions. Combination therapy consisting of conservative pectoral mastectomy and postoperative adjuvant chemo- endocrino-therapy (i.e., adjuvant therapy) has become the standard regimen for treating resectable locally advanced breast cancer, because it significantly improves the recurrence rate and survival rate compared to local treatment alone. Some clinical have studies indicated that neoadjuvant therapy (i.e., induction chemotherapy + surgery/radiation therapy) is comparable or superior to adjuvant therapy in terms of improving the prognosis. However, the efficacy and most appropriate method of breast-conserving therapy after induction chemotherapy are still unclear. More clinical trials are needed. It has been

    Background. Breast cancer is the most frequent malignant disease among women world wide. Survival has been improving leading to an increasing number of breast cancer survivors, in the US estimated to about 2.6 million. Material and methods. The literature was reviewed with focus on data from the Nordic countries. Results. Local therapies such as breast cancer surgery and radiotherapy may cause persistent pain in the breast area, arm, and shoulder reported by 30-50% of patients after three to five years, lymphedema in 15-25% of patients, and restrictions of arm and shoulder movement in 35%. Physiotherapy is the standard treatment for the latter while no pain intervention trials have been published. Chemotherapy may cause infertility and premature menopause, resulting in vasomotor symptoms, sexual dysfunction, and osteoporosis, which are similar to the side effects of endocrine treatment in postmenopausal women. Awareness of cardiotoxicity is needed since anthracyclines, trastuzumab, and radiotherapy can damage the heart. Breast cancer survivors have an increased risk of a major depression and far from all receive adequate anti-depressive treatment. Other psychological symptoms include fear of recurrence, sleep disturbances, cognitive problems, fatigue, and sexual problems. Discussion. To improve rehabilitation, specific goals have to be formulated into national guidelines and high priority directed towards research into developing and testing new interventions for alleviating symptoms and side effects experienced by breast cancer survivors

    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.

    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.

    Mammographic screening is effective in reducing mortality from breast cancer. The issue is not whether mammography is effective, but whether the false positive rate and false negative rates can be reduced. This review will discuss controversies including the reduction in breast cancer mortality, overdiagnosis, the ideal screening candidate, and the optimal imaging modality for breast cancer screening. The article will compare and contrast screening mammography, tomosynthesis, whole-breast screening ultrasound, magnetic resonance imaging, and molecular breast imaging. Though supplemental imaging modalities are being utilized to improve breast cancer diagnosis, mammography still remains the gold standard for breast cancer screening.

  2. The myth about contraceptives and breast cancer.

    Science and modern medicine accord us many advantages, e.g., contraceptive drugs, but many people still do not use them. Contraceptive drugs include oral contraceptives and injectables. OCs are very effective and are associated with minor side effects (e.g., mood changes, breast tenderness, nausea, and changes in weight, mild headache, and spotting between periods), perhaps explaining why they are one of the most often used contraceptive in essentially every country. Women who smoke; are 35 years old; or either have or have a family history of hypertension, diabetes, cardiovascular disease and use OCs are at higher risk of a cardiovascular episode. On the other hand, OCs protect against ovarian and endometrial cancers. Research does not yet confirm or disprove their effect on breast cancer development. OCs appear not to be linked to breast cancer through age 59. Yet, studies of women 45 years old suggest that OCs increases the breast cancer risk in these women who had their first menses before age 13 and used OCs for a long time before their first pregnancy. OCs may facilitate growth of breast tumors that other causes activated, and therefore, do not likely increase the overall risk. Researchers recognize the death of knowledge about breast cancer development, so they call for more research, including basic molecular, cellular, and biochemical studies. In Nigeria, breast cancer is rare, while deaths due to pregnancy and childbirth are common, indicating that OC use can prevent many female deaths. Prolonged breast feeding; later age at first menses; earlier age at menopause; earlier age at first full-term pregnancy larger families; low fat, high fiber diets; and thinness, all of which are common in developing countries, have a protective effect against breast cancer. Further, women in developing countries begin OC use later than women in developed countries.

    This is the first textbook of its kind devoted to describing the biological complexities of breast cancer in a way that is relevant to the radiation oncologist. Radiation Oncology has long treated breast cancer as a single biological entity, with all treatment decisions being based on clinical and pathologic risk factors. We are now beginning to understand that biological subtypes of breast cancer may have different risks of recurrence as well as different intrinsic sensitivity to radiotherapy. Multi-gene arrays that have for years been used to predict the risk of distant recurrence and the value of systemic chemotherapy may also have utility in predicting the risk of local recurrence. Additionally, the targeted agents used to treat breast cancer may interact with radiotherapy in ways that can be beneficial or undesirable. All of these emerging issues are extensively discussed in this book, and practical evidence-based treatment recommendations are presented whenever possible.

    Breast cancer is one of the most common types of cancer in women, and is the second leading cause of cancer-related deaths in the United States. Chemoprevention using phytoestrogens (PEs) for breast cancer may be a valid strategy. PEs are phytochemicals with estrogen-like structures and can be classified into four types: isoflavones, lignans, stilbenes and coumestans. They are widely distributed in diet and herbs and have shown anti-cancer activity via mechanisms including estrogen receptor modulation, aromatase inhibition, and anti-angiogenesis. Genistein, daidzein and resveratrol are some of the most studied PE examples. Quality control in product manufacturing and clinical study design is a critical issue in developing them as clinically effective chemopreventive agents for breast cancer.

    2012-01-01

    Background: Brain metastases (BM) are frequently diagnosed in patients with HER-2-positive metastatic breast cancer; in addition, an increasing incidence was reported for triple-negative tumours. We aimed to compare brain metastases free survival (BMFS) of breast cancer subtypes in patients treated between 1996 until 2010. Methods: Brain metastases free survival was measured as the interval from diagnosis of extracranial breast cancer metastases until diagnosis of BM. HER-2 status was analysed by immunohistochemistry and reanalysed by fluorescent in situ hybridisation if a score of 2+ was gained. Oestrogen-receptor (ER) and progesterone-receptor (PgR) status was analysed by immunohistochemistry. Brain metastases free survival curves were estimated with the Kaplan–Meier method and compared with the log-rank test. Results: Data of 213 patients (46 luminal/124 HER-2/43 triple-negative subtype) with BM from breast cancer were available for the analysis. Brain metastases free survival differed significantly between breast cancer subtypes. Median BMFS in triple-negative tumours was 14 months (95% CI: 11.34–16.66) compared with 18 months (95% CI: 14.46–21.54) in HER-2-positive tumours (P=0.001) and 34 months (95% CI: 23.71–44.29) in luminal tumours (P=0.001), respectively. In HER-2-positive patients, co-positivity for ER and HER-2 prolonged BMFS (26 vs 15 m; P=0.033); in luminal tumours, co-expression of ER and PgR was not significantly associated with BMFS. Brain metastases free survival in patients with lung metastases was significantly shorter (17 vs 21 months; P=0.014). Conclusion: Brain metastases free survival in triple-negative breast cancer, as well as in HER-2-positive/ER-negative, is significantly shorter compared with HER-2/ER co-positive or luminal tumours, mirroring the aggressiveness of these breast cancer subtypes.

    Objective: To observe growth inhibition effect of adeno-associated viral vectors (AAV) mediated angiostatin (ANG) gene on implanted breast cancer in rat and its mechanism. Methods: Gene transfer technique was used to transfer AAV-ANG to the tumor. Growth curves were drawn to observe the growth of breast cancer implanted in rat, and immunohistochemical method was used to detect the effects of angiostatin on microvesel density (MVD) of breast cancer implanted in rat. Results: Angiostatin inhibited the growth of breast cancer implanted in rat and decreased the microvessel density of tumor. Conclusion: Expression of an angiostatin transgene can suppress the growth of breast cancer implanted in rat through the inhibition of the growth of microvessels, surggesting that angiostatin gene transfer technique may be effective against breast cancer.

    Breast cancer is the most prevalent malignancy among women under 50. Improvements in diagnosis and treatment have yielded an important decrease in mortality in the last 20 years. In many cases, chemotherapy and radiotherapy develop side effects on the reproductive function. Therefore, before the anti-cancer treatment impairs fertility, clinicians should offer some techniques for fertility preservation for women planning motherhood in the future. In order to obtain more available oocytes for IVF, the ovary must be stimulated. New protocols which prevent exposure to increased estrogen during gonadotropin stimulation, measurements to avoid the delay in starting anti-cancer treatment or the outcome of ovarian stimulation have been addressed in this review. There is no evidence of association between ovarian stimulation and breast cancer. It seems that there are more relevant other confluent factors than ovarian stimulation. Factors that can modify the risk of breast cancer include: parity, age at full-term birth, age of menarche, and family history. There is an association between breast cancer and exogenous estrogen. Therefore, specific protocols to stimulate patients with breast cancer include anti-estrogen agents such as letrozole. By using letrozole plus recombinant follicular stimulating hormone, patients develop a multifollicular growth with only a mild increase in estradiol serum levels. Controlled ovarian stimulation (COS) takes around 10 days, and we discuss new strategies to start COS as soon as possible. Protocols starting during the luteal phase or after inducing the menses currently prevent a delay in starting ovarian stimulation. Patients with breast cancer have a poorer response to COS compared with patients without cancer who are stimulated with conventional protocols of gonadotropins. Although many centres offer fertility preservation and many patients undergo ovarian stimulation, there are not enough studies to evaluate the recurrence, breast cancer

    Breast conservation has become well-established in the treatment of early mammary carcinoma. However, a standardised treatment modality has not emerged. We have analysed the data from 1,973 patients treated in three consecutive randomised trials by four different radiosurgical procedures: Halsted mastectomy, quadrantectomy plus radiotherapy, lumpectomy plus radiotherapy, and quadrantectomy without radiotherapy, to compare the outcomes of these procedures in terms of local recurrence rate and overall survival. Eligibility criteria were similar in the three trials, and comparability between the four subgroups was excellent. Median follow-up for all patients was 82 months. The annual rates of local recurrence varied markedly according to the treatment. Patients treated with Halsted mastectomy and quadrantectomy plus radiotherapy had low annual rates of local recurrence (0.20 and 0.46, respectively) while both lumpectomy plus radiotherapy and quadrantectomy without radiotherapy had significantly higher rates (2.45 and 3.28, respectively). Patients under 45 years of age had a much higher incidence of local recurrences, while in women over 55 years local recurrences were much less frequent. Overall survival curves were identical in the four groups of patients, so that the three breast conserving radiosurgical procedures had the same survival rates as Halsted mastectomy. However, local recurrence rates were markedly influenced by the treatment method, patient age and specific histological features.

    A woman gains protection from breast cancer by completing a full-term pregnancy. In utero, her offspring produce hormones that mature 85 percent of the mother's breast tissue into cancer-resistant breast tissue. If the pregnancy ends through an induced abortion or a premature birth before thirty-two weeks, the mother's breasts will have only partially matured, retaining even more cancer-susceptible breast tissue than when the pregnancy began. This increased amount of immature breast tissue will leave the mother with more sites for cancer initiation, thereby increasing her risk of breast cancer. Hormonal contraceptives increase breast-cancer risk by their proliferative effect on breast tissue and their direct carcinogenic effects on DNA. Hormonal contraceptives include estrogen-progestin combination drugs prescribed in any manner of delivery: orally, transdermally, vaginally, or intrauterine. This article provides the detailed physiology and data that elucidate the mechanisms through which induced abortion and hormonal contraceptives increase breast-cancer risk.

    Ornithine decarboxylase (ODC), the rate-limiting enzyme in polyamine biosynthesis that decarboxylates ornithine to putrescine, has become a promising target for cancer research. The aim of this study is to investigate the role of ODC in breast cancer. We detected expression of ODC in breast cancer tissues and four breast cancer cell lines, and transfected breast cancer cells with an adenoviral vector carrying antisense ODC (rAd-ODC/Ex3as) and examined their growth and migration.ODC was overexpressed in breast cancer tissues and cell lines compared with non-tumor tissues and normal breast epithelial celis,and there was a positive correlation between the level of ODC mRNA and the staging of tumors.The expression of ODC correlated with cyclin D1,a cell cycle protein,in synchronized breast cancer MDA-MB-231 cells.Gene transfection of rAd-ODC/Ex3as markedly down-regulated expression Of ODC and cyclin D1,resulting in suppression of proliferation and cell cycle arrest at G0-G1 phase,and the inhibifion of colony formation,an anchorage-independent growth pattern,and the migratory ability of MDA-MB-231 cells.rAd-ODC/Ex3as also markedly reduced the concentration of putrescine,but not spermidine or spermine,in MDA-MB-231 cells.The results suggested that the ODC gene might act as aprognostic factor for breast cancer and it could be a promising therapeutic target.
