    A review of the surgical cases of Harvey Cushing, MD, at The Johns Hopkins Hospital provided insight into his early work treating breast cancer metastasis to the central nervous system (CNS). At the time, neurologic surgery was in its infancy. Metastases of breast carcinoma to the CNS were recognized; however, many surgeons of the era adhered to a general principle of not operating in these situations. The Johns Hopkins Hospital surgical records from 1896 to 1912 were reviewed. Four cases in which Cushing treated patients with a history of breast cancer who were diagnosed as having CNS metastasis were selected for further study. Cushing performed surgery on 4 patients with suspected CNS metastasis in the early 1900s. For a spinal metastasis, Cushing performed a laminectomy and intradural exploratory surgery. His treatments in cerebral cases sought to relieve increased intracranial pressure through decompression. He resected the lesions when they could be located. From the start of his career as a neurosurgeon, Cushing chose to perform surgery on patients with suspected CNS metastasis in an attempt to palliate some of their symptoms. Although his patients did not survive long after the procedures, they did experience temporary relief of symptoms that likely encouraged Cushing's continued operations in such situations and laid the foundation for future therapies for these patients.

    This qualitative study aimed to achieve an understanding of women's experiences of immediate breast reconstruction following mastectomy, to better understand the factors influencing patient satisfaction. Nine women were recruited from a breast unit in the North West of England. Participants were 3-9 months post-reconstruction, had received either an implant-based or Latissimus Dorsi-based immediate reconstruction and were not receiving any adjuvant therapies. An inductive qualitative and phenomenological approach was adopted to data collection and analysis. Women took part in semi-structured interviews. All interviews were transcribed and analysed using thematic analysis. Four themes were generated: Seeking and receiving information; coping with the outcome of reconstruction; the need for on-going support and a new life after surgery. The study highlights difficulties surrounding receiving information and decision-making, how women make sense of recovery, how they solicit and receive support, and the process by which they begin to make sense of their futures. More focus on these areas in service provision may aid positive psychological outcomes in the recovery process following immediate breast reconstruction. © 2014 The British Psychological Society.

    This article examines how faith community nurses (FCNs) fostered early breast cancer detection for those at risk in rural and African American populations throughout nine counties in midwestern Illinois to decrease breast cancer disparities. Flexible methods for breast cancer awareness education through FCNs, effective strategies for maximizing participation, and implications for practice were identified. In addition, networking within faith communities, connecting with complementary activities scheduled in those communities, and offering refreshments and gift items that support educational efforts were identified as effective ways of maximizing outcomes and reinforcing learning. Flexible educational programming that could be adapted to situational and learning needs was important to alleviate barriers in the project. As a result, the number of participants in the breast cancer awareness education program exceeded the grant goal, and the large number of African American participants and an unexpected number of Hispanic and Latino participants exceeded the target.

    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).

    The demand for reconstructive breast surgery after mastectomy is increasing among women and the two-stage option remains the most commonly performed technique. We conducted a self-controlled prospective clinical trial comparing the use of the serratus anterior fascia with the serratus anterior detached fibers to cover the inferolateral aspect of the expander in immediate two-stage breast reconstruction following conservative mastectomies as oncological or risk-reducing procedures. We analyzed the surgical outcome of 29 bilateral mastectomies and immediate reconstruction with the positioning of a tissue expander in a pocket beneath the pectoralis major and serratus anterior muscle on one side and in a pocket beneath the pectoralis major and a serratus anterior fascia flap on the other side. We considered all complications presenting in the first month after surgery and patient-reported early post-operative pain. Complication rates in the two groups did not significantly differ (p = 0.237). The total amount of drainage and the time of drainage permanence were significantly lower for the subfascial group (p < 0.05). Patient-reported early post-operative pain was significantly different between the two groups both at 24 h (p < 0.05) and at 5 days (p < 0.05) with significantly lower pain scores reported by the patients in the subfascial group. Our self-controlled prospective trial demonstrated an advantage in performing an implant-based two-stage breast reconstruction using a serratus anterior fascia flap when compared with the serratus muscle fibers use for inferolateral implant coverage following mastectomy. The use of the anterior serratus fascia flap for inferolateral implant coverage in two-stage breast reconstructions following mastectomy could be considered as a safe and effective technique, presenting lower morbidity for the patient when compared with the serratus muscle fibers use and lower costs when compared with biological and synthetic meshes use

    Breast conserving therapy for women with breast cancer consists of local excision of the tumour (achieving clear margins) followed by radiation therapy (RT). RT is given to sterilize tumour cells that may remain after surgery to decrease the risk of local tumour recurrence. Most true recurrences occur in the same quadrant as the original tumour. Whole breast RT may not protect against the development of a new primary cancer developing in other quadrants of the breast. In this Cochrane Review, we investigated the role of delivering radiation to a limited volume of the breast around the tumour bed (partial breast irradiation: PBI) sometimes with a shortened treatment duration (accelerated partial breast irradiation: APBI). To determine whether PBI/APBI is equivalent to or better than conventional or hypofractionated WBRT after breast conservation therapy for early-stage breast cancer. We searched the Cochrane Breast Cancer Group Specialised Register (07 November 2013), CENTRAL (2014, Issue 3), MEDLINE (January 1966 to 11 April 2014), EMBASE (1980 to 11 April 2014), CINAHL (11 April 2014) and Current Contents (11 April 2014). Also we searched the International Standard Randomised Controlled Trial Number Register, the World Health Organization's International Clinical Trials Registry Platform (07 November 2013) and US clinical trials registry (www.clinicaltrials.gov) (22 April 2014).

    Early detection of breast cancer depends upon a high index of clinical suspicion as screening programmes are not yet generally available in the United Kingdom. The symptoms and signs of operable breast cancer in 1,205 women presenting prospectively and unselected to the surgical clinics of members of the Yorkshire Breast Cancer Group from 1976 to 1981 are reviewed. Seventy-three per cent of the women were postmenopausal. Seventy-six per cent of the patients presented with a discrete lump. Pain as a presenting symptom was rare, but when questioned 33 per cent of the women admitted that the lump was painful. Forty-two per cent of patients had skin tethering or fixation, but only 22 per cent had nipple retraction or displacement. Forty-two per cent of women had lesions which appeared to have well-defined edges. Only 32 per cent of lesions were clinically T0 or T1, the majority (56 per cent) being T2, and 12 per cent were T3. Standard descriptions of symptoms and signs in breast cancer have so far failed to define in what percentage of patients, diagnostic features are present, and have also omitted to emphasize that in a considerable proportion of women classical signs may be absent. Any breast lump in a postmenopausal woman must be considered malignant until proved otherwise and it is wise to pursue an active diagnostic policy in the premenopausal patient, with early referral for a surgical opinion in both cases.

    Purpose: To present local control, complications, and cosmetic outcomes of intraoperative radiation therapy (IORT) for early breast cancer, as well as technical aspects related to the use of a nondedicated linear accelerator. Methods and Materials: This prospective trial began in May of 2004. Eligibility criteria were biopsy-proven breast-infiltrating ductal carcinoma, age >40 years, tumor <3 cm, and cN0. Exclusion criteria were in situ or lobular types, multicentricity, skin invasion, any contraindication for surgery and/or radiation therapy, sentinel lymph node involvement, metastasis, or another malignancy. Patients underwent classic quadrantectomy with intraoperative sentinel lymph node and margins evaluation. If both free, the patient was transferred from operative suite to linear accelerator room, and IORT was delivered (21 Gy). Primary endpoint: local recurrence (LR); secondary endpoints: toxicities and aesthetics. Quality assurance involved using a customized shield for chest wall protection, applying procedures to minimize infection caused by patient transportation, and using portal films to check collimator-shield alignment. Results: A total of 152 patients were included, with at least 1 year follow-up. Median age (range) was 58.3 (40-85.4) years, and median follow-up time was 50.7 (12-110.5) months. The likelihood of 5-year local recurrence was 3.7%. There were 3 deaths, 2 of which were cancer related. The Kaplan-Meier 5-year actuarial estimates of overall, disease-free, and local recurrence-free survivals were 97.8%, 92.5%, and 96.3%, respectively. The overall incidences of acute and late toxicities were 12.5% and 29.6%, respectively. Excellent, good, fair, and bad cosmetic results were observed in 76.9%, 15.8%, 4.3%, and 2.8% of patients, respectively. Most treatments were performed with a 5-cm collimator, and in 39.8% of the patients the electron-beam energy used was ≥12 MeV. All patients underwent portal film evaluation, and the shielding was

    Breast cancer is the most common cancer in women worldwide, identification of new biomarkers for early diagnosis and detection will improve the clinical outcome of breast cancer patients. In the present study, we determined serum levels of vitronectin (VN) in 93 breast cancer patients, 30 benign breast lesions, 9 precancerous lesions, and 30 healthy individuals by enzyme-linked immunosorbent assays. Serum VN level was significantly higher in patients with stage 0-I primary breast cancer than in healthy individuals, patients with benign breast lesion or precancerous lesions, as well as those with breast cancer of higher stages. Serum VN level was significantly and negatively correlated with tumor size, lymph node status, and clinical stage (p < 0.05 in all cases). In addition, VN displayed higher area under curve (AUC) value (0.73, 95 % confidence interval (CI) [0.62-0.84]) than carcinoembryonic antigen (CEA) (0.64, 95 % CI [0.52-0.77]) and cancer antigen 15-3 (CA 15-3) (0.69, 95 % CI [0.58-0.81]) when used to distinguish stage 0-I cancer and normal control. Importantly, the combined use of three biomarkers yielded an improvement in receiver operating characteristic curve with an AUC of 0.83, 95 % CI [0.74-0.92]. Taken together, our current study showed for the first time that serum VN is a promising biomarker for early diagnosis of breast cancer when combined with CEA and CA15-3.

    SYNOPSIS Breast cancer is a disease associated with aging; there is a rise in both breast cancer incidence and mortality with increasing age. With the aging of the US population, the number of older adults diagnosed with breast cancer and the number of breast cancer survivors is on the rise. The majority of cases of breast cancer are diagnosed with early stage (non-metastatic) potentially curable disease. This article will review the treatment of early stage breast cancer in older adults including a focus on the risks and benefits of surgery, radiation therapy, endocrine therapy, chemotherapy, and trastuzumab. Although the majority of studies to date demonstrate that older adults experience similar benefits from most multimodality treatments for breast cancer as compared to younger adults, these studies have primarily been performed in healthy and fit older adults. There are limited data at the extremes of age or in those patients with significant comorbidity or functional decline. A primary question facing the doctor and patient is whether the breast cancer is likely to impact the patient’s life expectancy or quality of life. If so, then the risks and benefits of treatment must be considered with a final decision regarding therapy made in the context of the patient’s preferences. This article will review the toxicities (both short- and long-term) from common cancer therapies in early breast cancer. Finally, the decision as to type of secondary screening and prevention of future breast cancers must also be weighed against the life expectancy of the older adult. PMID:22326036

    Two types of prognostic signatures for predicting recurrent risk of ER+ breast cancer patients have been developed: one type for patients accepting surgery only and another type for patients receiving post-operative tamoxifen therapy. However, the first type of signature cannot distinguish high-risk patients who cannot benefit from tamoxifen therapy, while the second type of signature cannot identify patients who will be at low risk of recurrence even if they accept surgery only. In this study, we proposed to develop two coupled signatures to solve these problems based on within-sample relative expression orderings (REOs) of gene pairs. Firstly, we identified a prognostic signature of post-operative recurrent risk using 544 samples of ER+ breast cancer patients accepting surgery only. Then, applying this drug-free signature to 840 samples of patients receiving post-operative tamoxifen therapy, we recognized 553 samples of patients who would have been at high risk of recurrence if they had accepted surgery only and used these samples to develop a tamoxifen therapy benefit predictive signature. The two coupled signatures were validated in independent data. The signatures developed in this study are robust against experimental batch effects and applicable at the individual levels, which can facilitate the clinical decision of tamoxifen therapy.

    This article is the report of a study aimed at determining whether or not expressive writing improves the quality-of-life of early breast cancer survivors. An additional aim is the investigation of whether or not the type of writing prompt makes a difference in results. The risk of distress can extend well beyond the time of a breast cancer diagnosis. Emotional expression may assist in dealing with this. Randomized controlled study. Participants (n = 120) were randomized into one of four groups: a control group (no writing) or one of three expressive writing groups: breast cancer trauma, any self-selected trauma and facts related to breast cancer. Participants wrote 20 minutes a day for 4 consecutive days. Their quality-of-life was measured, using the 'Functional Assessment of Cancer Therapy-Breast Cancer Version', at baseline and at 1 month and 6 months after writing. Paired t-tests, multivariate analysis of variance and multiple regression were used to analyse the data of the 97 participants who completed the journaling assignment and at least the first assessment, collected in 2006. Intention-to-treat analysis was used. Expressive writing about one's breast cancer, breast cancer trauma and facts related to breast cancer, significantly improved the quality-of-life outcome. Expressive writing, focusing the instructions on writing about one's living and dealing with a diagnosis of breast cancer, is recommended for early breast cancer survivors as a feasible and easily implemented treatment approach to improve quality-of-life. © 2012 Blackwell Publishing Ltd.

    Objective Breast cancer is the most common type of cancer in women throughout the world. It is the second leading cause of cancer related deaths, after lung cancer. Breast cancer is the most common cancer in women in Turkey with a rate of 23,4%. One out of every four women has breast cancer. This study was conducted to determine the barriers on methods of early diagnosis of breast cancer. Materials and Methods The research population consisted of women over the age of 40 years who live in the neighborhood of Doğanlar (N=2404). The sample size was determined (n=251) with Epi İnfo Statcalc account program with 95% confidence interval, with the incidence of breast cancer accepted as 24%. Women over the age of 40 years who agreed to participate were included in the study. In order to collect the necessary data, a 27-item questionnaire including socio-demographic characteristics and methods of early diagnosis was created according to the literature. This study was conducted between March-October 2012 in Doğanlar neighborhood. Results Two-hundred-fifty-four women participated in the study, with a mean age of 54,27±1, and an average monthly income of 895,0197 TL (min=0 TL, max=7000 TL). 79,1% were married, 89,8% were housewives, 56,7% were literate, and 83,1% had health insurance. The status of performing regular Breast Self Examination (BSE) was significantly higher in women who had knowledge about BSE, (p=0.000). Married (p=0.015) women and those who had a social security system (p=0.048) had significantly higher rates of mammography. Women who were informed on mammography (p=0.000) had significantly higher rates of mammography. When reasons for not getting mammography was addressed, it was observed that 99,2% was due to lack of information and education. Women who had regular BSE had significantly higher Clinical Breast Examination (CBE) (p=0.024). Women’s sociodemographic characteristics did not affect the status of performing regular BSE and CBE significantly

    Mammographic detection of breast cancer at the earliest possible stage requires optimal radiographic technique and a full knowledge of the subtle features with which very small cancers can present. Although some early cancers are identified as characteristic clusters of calcifications or as spiculated or multinodular (knobby) masses, others demonstrate less typical and sometimes much less obvious mammographic signs: the single dilated duct, focal architectural distortion, asymmetry, and the developing density sign. Although these indirect signs are nonspecific, they provide mammographers with the important opportunity to discover breast cancer at a very early stage, when the likelihood for cure is great.

    The frequent occurrence of breast cancer and its serious consequences have attracted worldwide attention in recent years. Problems such as low rate of accuracy and poor self-adaptability still exist in traditional diagnosis. In order to solve these problems, an AdaBoost-SVM classification algorithm, combined with the cluster boundary sampling preprocessing techniques (CBS-AdaBoost-SVM), is proposed in this paper for the early diagnosis of breast cancer. The algorithm uses machine learning method to diagnose the unknown image data. Moreover, not all of the characteristics play positive roles for classification. To address this issue the paper delete redundant features by using Rough set attribute reduction algorithm based on the genetic algorithm (GA). The effectiveness of the proposed methods are examined on DDSM by calculating its accuracy, confusion matrix, and receiver operating characteristic curves, which give important clues to the physicians for early diagnosis of breast cancer.

    Expert consensus-based recommendations regarding key issues in the use of primary (or neoadjuvant) systemic treatment (PST) in patients with early breast cancer are a valuable resource for practising oncologists. PST remains a valuable therapeutic approach for the assessment of biological antitumor activity and clinical efficacy of new treatments in clinical trials. Neoadjuvant trials provide endpoints, such as pathological complete response (pCR) to treatment, that potentially translate into meaningful improvements in overall survival and disease-free survival. Neoadjuvant trials need fewer patients and are less expensive than adjuvant trial, and the endpoint of pCR is achieved in months, rather than years. For these reasons, the neoadjuvant setting is ideal for testing emerging targeted therapies in early breast cancer. Although pCR is an early clinical endpoint, its role as a surrogate for long-term outcomes is the key issue. New and better predictors of treatment efficacy are needed to improve treatment and outcomes. After PST, accurate management of post-treatment residual disease is mandatory. The surgery of the sentinel lymph-node could be an acceptable option to spare the axillary dissection in case of clinical negativity (N0) of the axilla at the diagnosis and/or after PST. No data exists yet to support the modulation of the extent of locoregional radiation therapy on the basis of the response attained after PST although trials are underway. PMID:26063896

    Expert consensus-based recommendations regarding key issues in the use of primary (or neoadjuvant) systemic treatment (PST) in patients with early breast cancer are a valuable resource for practising oncologists. PST remains a valuable therapeutic approach for the assessment of biological antitumor activity and clinical efficacy of new treatments in clinical trials. Neoadjuvant trials provide endpoints, such as pathological complete response (pCR) to treatment, that potentially translate into meaningful improvements in overall survival and disease-free survival. Neoadjuvant trials need fewer patients and are less expensive than adjuvant trial, and the endpoint of pCR is achieved in months, rather than years. For these reasons, the neoadjuvant setting is ideal for testing emerging targeted therapies in early breast cancer. Although pCR is an early clinical endpoint, its role as a surrogate for long-term outcomes is the key issue. New and better predictors of treatment efficacy are needed to improve treatment and outcomes. After PST, accurate management of post-treatment residual disease is mandatory. The surgery of the sentinel lymph-node could be an acceptable option to spare the axillary dissection in case of clinical negativity (N0) of the axilla at the diagnosis and/or after PST. No data exists yet to support the modulation of the extent of locoregional radiation therapy on the basis of the response attained after PST although trials are underway. © The Author 2015.

    Risks for breast cancer when there is a family history of the disease are usually calculated using data from segregation analyses which favour a single dominant gene with high penetrance. There are, however, at least three loci known to be associated with familial breast cancer (p53, BRCA1, and an as yet unpublished locus) and the frequencies and penetrances of these genes are not likely to be the same. We have attempted to address the problem of which genetic parameters should be used to calculate risks for different patterns of familial breast cancer. Data from 384 nuclear families ascertained through a proband selected for early onset breast cancer were subjected to complex segregation analysis, correcting for ascertainment bias resulting from selection for severe phenotype. Age of onset of breast cancer, incorporated as severity, provides additional information to the segregation model over and above that given by assigning liability classes on the basis of age at observation. The use of this additional parameter in the analysis is described. There is fair agreement between estimates from this sample and previous predictions from consecutive probands and consultands. The differences suggest more than one rare dominant gene for susceptibility to breast cancer, with different penetrances. Although refinements of segregation analysis will help to delineate these different genes, perfect resolution will require identification of the mutant alleles. Methods to estimate genetic parameters under genotype specific mortality need to be developed. Meanwhile, we suggest that high and low estimates of penetrance be used in risk estimation for genetic counselling, and as a guide to candidates for entry into clinical trials of screening and chemoprevention in breast cancer.

    Radiotherapy is an indispensible part of the management of all stages of breast cancer. In this article, the common indications for radiotherapy in the management of early breast cancer (stages 0, I, and II) are reviewed, including whole-breast radiotherapy as part of breast-conserving treatment for early invasive breast cancer and pre-invasive disease of ductal carcinoma in situ, post-mastectomy radiotherapy, locoregional radiotherapy, and partial breast irradiation. Key clinical studies that underpin our current practice are discussed briefly.

    Purpose Accelerated whole breast irradiation (AWBI) and conventional whole breast irradiation (CWBI) were compared to determine whether AWBI is as effective as CWBI in patients with early breast cancer and adverse prognostic features. Patients and methods We included 330 patients who underwent breast-conserving surgery (BCS) and post-operative radiation therapy (RT) using AWBI for pT1-2 and pN0-1a breast cancer from 2007 to 2010. These patients were matched with 330 patients who received CWBI according to stage, age (±3 years), and the year of BCS. AWBI of 39 Gy and CWBI of 50.4 Gy were given in 13 and 28 fractions, respectively. Results Median follow-up time was 81.9 months. There were no statistically significant differences between the AWBI and CWBI groups in terms of age, stage, tumor grade, or molecular subtype. More patients with Ki-67 index ≥ 14% were present in the AWBI group (AWBI 47.0% vs. CWBI 10.3%; P<0.01). The 5-year ipsilateral breast tumor relapse (IBTR) rates for the AWBI and CWBI groups were 0.8% and 1.8%, respectively (P=0.54). High tumor grade was a statistically significant risk factor for IBTR (5-year IBTR rate: 2.9%; P=0.01). Ki-67 ≥ 14% was marginally related to IBTR (5-year IBTR rate: 2.2%; P=0.07). There were no statistically significant differences in the hazard ratios between the AWBI and CWBI groups according to any of the risk factors. There were no acute grade 3 toxicities in the AWBI group. There were no late grade 3 toxicities in either group. Conclusions AWBI is comparable to CWBI in early breast cancer with adverse prognostic features. PMID:27588485

    Summary Breast cancer is increasing in developing countries, and Colombia has a double burden from cervical and breast cancer. Suitable guidelines for breast cancer early detection are needed, and the Breast Health Global Initiative provides a favorable framework for breast cancer control in low resource nations. The Colombian National Cancer Institute developed evidence-based guidelines for breast cancer early detection in which coordinated early detection in symptomatic women and hospital-based screening in women aged 50–69 are recommended. A pilot project to evaluate programmatic approaches (opportunistic screening) was designed, and it is expected that organized hospital-based screening for breast cancer will represent a move towards population-based screening in the near future in accordance with country specific conditions.

    We have studied the incidence of microsatellite instability at three trinucleotide repeats and seven dinucleotide repeats from five chromosomal regions, in a group of 30 mammographically detected 'early' invasive breast cancers and correlated its occurrence with clinicopathological parameters. The myotonic dystrophy (DM-1) trinucleotide repeat was analysed in 48 additional cases. In 4 out of 78 (5%) paired tumour-normal DNA samples we found evidence of somatic microsatellite instability at DM-1: a novel allele of a different size was seen in the tumour DNA which was not present in the normal DNA sample. All four tumours that showed evidence of instability were from the core group of 30 cases (13%) and were well or moderately differentiated, oestrogen receptor-positive, infiltrating ductal carcinomas. Two of these tumours were unstable at nine of ten loci studied, both trinucleotide and dinucleotide repeats. DNA prepared from different normal tissues showed no evidence of instability, for all four instability cases. These data indicate that microsatellite instability is specific to the tumour DNA and is an early event in the genesis of some sporadic breast cancers. Images Figure 1 PMID:8645585

    To assess and compare the impact on skin reactions and cosmesis between hypofractionated whole breast and conventional irradiation for early breast cancer. Seventy-three patients with operable breast cancer (pT1-3pN0-1M0) who underwent breast-conserving surgery were assigned for irradiation to either conventional arm (50 Gy in 25 fractions) with a sequential electron boost of 15-16 Gy over five weeks or hypofractionated arm (43.2 Gy in 16 fractions) with a concomitant electron boost of 0.6 Gy over three weeks. At 3-week follow-up, skin toxicities in the hypofractionated arm were significantly worse than that seen in the conventional arm, while at 6-week follow-up, the percentages of skin toxicities in the conventional arm were higher After a median follow-up of six months, there was no significant difference in skin toxicities between the two treatment groups. In addition, there were no significant differences in the mean scores of cosmetic outcome for patients between two regimens. This hypofractionated radiotherapy regimen of 43.2 Gy in 16 fractions with a concomitant electron boost showed good results in terms of normal tissue effects and cosmesis. A long-term follow-up is needed to confirm these favorable results.

    Endoscopic surgery is reportedly associated with smaller scars and greater patient satisfaction. Herein we evaluate the early results of endoscopy-assisted breast-conserving surgery(E-BCS). Between May 2009 and October 2010, 61 women with breast cancer underwent E-BCS. We performed E-BCS on patients with tumors measuring less than 2 cm, without skin or pectoralis muscles invasion. Any patients with microcalcified lesions or axillary lymph node metastasis were excluded. We used an endoscopic vein retractor to dissect the dorsal layer of the mammary gland from a small axillar incision. We dissected the subcutaneous layer and cut the mammary gland vertically from a periareolar incision. We evaluated the clinicopathological characteristics, the surgical outcomes, and early cosmetic results. The mean age of the patients was 58.5 years, and the mean tumor size was 1.4 cm. Sentinel node biopsy was positive in seven patients, all of whom underwent axillary node dissection. An additional intraoperative resection of the breast was performed in 12 patients. The mean length of the operation was 167 min, and the mean blood loss was 27 mL. Eight patients received a boost to the tumor bed. The cosmetic results were satisfactory, and the wound scar was inconspicuous in most patients. Herein we demonstrate that E-BCS is a feasible and safe procedure for patients with early breast cancer. It allows for a better cosmetic scar location and offers patients favorable aesthetic results in the short-term follow-up results. © 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    Decision about the administration of adjuvant therapy for early breast cancer depends on the evaluation of prognostic factors. Lymph node status, tumor size and grade of differentiation are classical variables in this regard, and can be complemented by hormonal receptor status and HER2 expression. These factors can be combined into prognostic indexes to better estimate the risk of relapse or death. Other factors are less important. Gene profiles have emerged in recent years to identify low-risk patients who can forgo adjuvant chemotherapy. A number of profiles are available and can be used in selected cases. In the future, gene profiling will be used to select patients for treatment with new targeted therapies.

    Purpose: To compare the quality-adjusted life expectancy between women treated with partial breast irradiation (PBI) vs. whole breast radiotherapy (WBRT) for estrogen receptor-positive early-stage breast cancer. Methods and Materials: We developed a Markov model to describe health states in the 15 years after radiotherapy for estrogen receptor-positive early-stage breast cancer. Breast cancer recurrences were separated into local recurrences and elsewhere failures. Ipsilateral breast tumor recurrence (IBTR) risk was extracted from the Oxford overview, and rates and utilities were adapted from the literature. We studied two cohorts of women (aged 40 and 55 years), both of whom received adjuvant tamoxifen. Results: Assuming a no evidence of disease (NED)-PBI utility of 0.93, quality-adusted life expectancy after PBI (and WBRT) was 12.61 (12.57) and 12.10 (12.06) years for 40-year-old and 55-year-old women, respectively. The NED-PBI utility thresholds for preferring PBI over WBRT were 0.923 and 0.921 for 40-year-old and 55-year-old women, respectively, both slightly greater than the NED-WBRT utility. Outcomes were sensitive to the utility of NED-PBI, the PBI hazard ratio for local recurrence, the baseline IBTR risk, and the percentage of IBTRs that were local. Overall the degree of superiority of PBI over WBRT was greater for 55-year-old women than for 40-year-old women. Conclusions: For most utility values of the NED-PBI health state, PBI was the preferred treatment modality. This result was highly sensitive to patient preferences and was also dependent on patient age, PBI efficacy, IBTR risk, and the fraction of IBTRs that were local.

    The increasing demand on mammographic screening for early breast cancer detection, and the subtlety of early breast cancer signs on mammograms, suggest an automated image processing system that can serve as a diagnostic aid in radiology clinics. We present a fully automated algorithm for detecting clusters of microcalcifications that are the most common signs of early, potentially curable breast cancer. By using the contour map of the mammogram, the algorithm circumvents some of the difficulties encountered with standard image processing methods. The clinical implementation of an automated instrument based on this algorithm is also discussed.

    With long-term follow-up, the DBCG 77B trial demonstrates that oral single-agent cyclophosphamide significantly reduces the risk of recurrence and mortality as compared with no systemic therapy in pre-menopausal patients with high-risk early breast cancer. DBCG 77B is the only randomised trial assessing single-agent cyclophosphamide; and a second comparison suggests that its benefits are comparable to what may be achieved by classic CMF. The lack of benefits from adding methotrexate and fluorouracil to cyclophosphamide paved the way for combining cyclophosphamide with anthracyclines and later taxanes. DBCG 89D showed an incremental benefit in DFS and OS from substituting methotrexate with epirubicin. The advantage of anthracycline-containing three-drug combinations over CMF was confirmed by others and in the individual-patient EBCTCG meta-analysis, while standard AC or EC for four cycles not was superior to classic CMF. A further reduction in breast cancer mortality appeared in the EBCTCG meta-analysis from the addition of a taxane to a standard AC, while the substitution of cycles or drugs with a taxane was not associated with a reduction in mortality. No apparent benefit was observed in an early analysis of the DBCG 82C evaluating the addition of CMF to tamoxifen in post-menopausal high-risk breast cancer patients. Apart from menopausal status, the two trials had identical selection criteria, and the differences in outcome warranted a long-term follow-up of the 82C trial. After ten years of follow-up, CMF in the DBCG 82C was associated with a significant improvement in DFS; but even with 24 years of follow-up, mortality was not significantly improved. The diversity in outcome from the 77C and the 82B trials triggered further studies. The 77B trial used classic CMF with oral cyclophospamide, while a four-weekly intravenous CMF regimen was used in the 82B and C trials, and a three-weekly CMF regimen was used in the succeeding 89B and D trials.

    This study aimed to compare the effects of cabbage compression early breast care (CCEBC) and early breast care (EBC) on breast pain, breast hardness with general nursing breast care (GNBC) in primiparous women after cesarean birth. Sixty participants were divided to three groups including CCEBC, EBC and GNBC. Each group was treated with its intervention respectively more than 10 minutes before breast feeding from day two to day four after delivery. The primary outcomes were breast pain and breast hardness. Both CCEBC and EBC showed significantly lower pain level than GNBC at day 4 after delivery. There are significant differences of breast hardness among three groups. CCEBC group showed significantly lower breast hardness compared with EBC and GNBC. Neither core body temperature nor breast skin temperature was significantly different among the three groups. In conclusion, CCEBC may effective in relieving breast pain and breast hardness compared with EBC alone and GNBC in primiparous women after a cesarean birth. PMID:26885074

    Because of its minimally invasive and highly accurate nature, the use of Mammotome, a vacuum-assisted breast biopsy device has proven beneficial to the treatment of benign breast lesions. Taking advantage of endoscopic and Mammotome techniques together, we utilized the Mammotome device for therapeutic excision of malignant lesions in breast-conserving surgery (BCS). Between December 2009 and January 2010, two patients with early breast cancer received Mammotome-assisted endoscopic BCSs. Under ultrasound monitoring, the Mammotome system dissected the surrounding tissue and freed the tumor en bloc leaving negative margins; endoscopic axillary lymph node dissection then followed. The operation time was less than 180 minutes and the mean blood loss was 60 ml. The post-operative pathology report confirmed two patients to have invasive ductal carcinoma, one without axillary lymph nodes metastasis (0/11) and the other with one lymph node metastasis (1/21). No adverse events were noted. During a mean follow-up of 26.5 months, no evidence of recurrence or metastasis was found. The patients were satisfied with the cosmetic results. Mammotome-assisted endoscopic surgery appears to be a valuable option for early breast cancer. The long-term therapeutic effect remains to be confirmed.

    Most of the information in medical literature report diverse factors of breast cancer, which are related to the reproductive life of the woman. It is mentioned that menarche before the 12 years elevates the relative risk of this disease, in comparison with its appearance after the 13 years. To determine if early menarche is a risk factor associated to breast cancer. This retrospective, observational and descriptive study included 162 women with breast cancer from a 3 years period (2002-2004), in the Juarez Hospital of Mexico. In addition other well known risk factors for breast cancer were evaluated. The statistical analysis was made with the software program SPSS; the descriptive analysis was made by means of summary of statistics, histograms, box and bar charts. Early menarche doesn't have correlation with breast cancer nor with the appearance of the disease in early ages; it was present in the 12.3% (n = 20) of the patients; the menarche initiated between 12 and 13 years in 64.4% (n = 104.3) of the cases. The average age at the time of the diagnosis of breast cancer in the early menarche group was of 55 years and for the group in general of 47.6 years. The factor that seems to be related to breast cancer is overweight and obesity with 54.26 and 17.11% respectively, with an average body mass index of 27.7 kg/m2. There was not a correlation between early menarche as risk factor for breast cancer neither between the reproductive risk factors considered habitual and increased risk of breast cancer. Overweight and obesity seem to be related to the appearance of the disease, reason why it is required to investigate this with different random control groups in the country. We propose to study other factors that may be implicated in the genesis of breast cancer such as inflammatory factors, similar insulin growth factors and hyperinsulinism.

    The approach to the axilla is an evolving paradigm, and recognition of the complexity of breast cancer (BC) biology is changing treatment options. The sentinel lymph node biopsy (SLNB) technique is based on the excision and histological examination of the axillary lymph nodes(s), which is assumed to be the first one draining from the primary tumor. SLNB can accurately stage the axilla, and several trials have shown that there are no significant differences in local recurrence and overall survival between patients treated with or without axillary node dissection (ALND) after a negative SLNB. Surgical morbidity was significantly reduced in terms of rates of lymphedema and neuropathy, with reduced hospital stay and better quality of life after the SLNB procedure. ALND can safely be omitted in patients with ≥2 positive nodes who received conservative surgery and radiotherapy, while ALND is still recommended in clinically N1 BCs, in case of ≥3 positive nodes, and when the number of positive nodes would be crucial for the choice of chemotherapy. Micrometastatic disease can be safely managed with SLNB alone, and additional identification of micrometastases with immunohistochemistry does not affect disease-free survival or overall survival. An appropriate management of the axilla is crucial for the outcome of patients with early BC, and SLNB introduction into the clinical practice dramatically changed the surgical treatment, reducing morbidity without decreasing survival. A tailored approach should be suggested in each patient with BC, considering the biology of the tumor rather than nodal involvement.

    PubMed

    Johns, N; Dixon, J M

    2016-11-01

    Breast conserving therapy (BCT) for breast cancer aims to achieve long-term local disease control with reduced local morbidity. BCT has similar long-term survival outcomes to mastectomy in patients with early breast cancer and recent studies have reported similar rates of recurrence compared with mastectomy. An increasing number of studies have shown improved overall survival among women treated with BCT regardless of cancer phenotype compared with mastectomy. Despite BCT being at least equivalent in outcome to mastectomy many women with small breast cancers continue to be treated by mastectomy and several studies in the last decade have shown a trend of increasing numbers of unilateral and bilateral mastectomies. The advent of increasingly effective neoadjuvant treatment has allowed even more women to have breast conservation. Not only has neoadjuvant therapy been shown to increase the rates of BCT, it does so without increasing in breast recurrence rates. Patients who are suitable for BCT should be advised that BCT is the best treatment option for them. They should be informed that not only does it confer at least equivalent survival and local recurrence rates but that compared with mastectomy it has the advantages of less complications, better quality of life and many less operations if reconstructive surgery is performed. It may no longer be appropriate to offer women suitable for BCT the choice of mastectomy or BCT.

    Increasing rate of breast cancer in Japan is enormous in these years. Nevertheless only 2-3 % of female may receive mammography. In order to improve this number for early detection of breast cancer we have started development of a refraction-based visualization of breast cancer. This system comprises two types of imaging: one is for a regular annual or biyearly check of the breast cancer. This is a 2-D mode x-ray dark-field imaging where a Laue transmission type of angle analyzer with thickness of 2.124 mm is used for the FOV of 90 mm x 90 mm that can provide the spatial resolution better than 50 microns; the other a 3-D reconstruction for further detailed check to specify type and location of breast cancer.

    Microwave-induced thermoacoustic tomography (TAT) is a noninvasive modality based on the differences in microwave absorption of various biological tissues. In this paper, the feasibility of the early breast tumor detection by TAT system has been discussed and validated experimentally. A fast TAT system, which based on three 128-elements transducers, a 384-64ch switch and a parallel data acquisition system (DAS), was developed to reconstruct the three-dimensional (3D) image of a breast model with similar microwave absorption coefficient to breast tissue. A novel method to explore the ability of TAT system to distinguish absorption coefficient was introduced and the minimum absorption coefficient difference that can be distinguished clearly by our TAT system is 12 m(-1). The potential applications of the TAT system were clearly demonstrated by successfully mapping breast model with mimicked tumors and microcalcification. An imaging experiment of human breast tumor embedding in the breast model was performed and the tumor was visualized by the 3D thermoacoustic volume. The thermoacoustic images match well with the samples and achieve penetration depth of 6 cm. The experimental results indicate that TAT has a great potential to be used for detecting early-stage breast cancers with high contrast and high resolution.

    Purpose Nearly 1 in 4 breast cancers is diagnosed before the age of 50, and many early-stage premalignant lesions are present but not yet diagnosed. Therefore, we review evidence to support the strategy that breast cancer prevention efforts must begin early in life. Methods Literature review Results Exposures during childhood and adolescence affect a woman’s long-term risk of breast cancer, but have received far less research attention than exposures that occur later in life. Breast tissue undergoes rapid cellular proliferation between menarche and first full-term pregnancy, and risk accumulates rapidly until the terminal differentiation that accompanies first pregnancy. Evidence on childhood diet and growth in height, and adolescent alcohol intake, among other adolescent factors are related to breast cancer risk and risk of premalignant proliferative benign lesions. Conclusion Breast cancer prevention efforts will have the greatest effect when initiated at an early age and continued over a lifetime. Gaps in knowledge are identified and deserve increase attention to inform prevention. PMID:24820413

    Abstract There has not been a clear answer about the efficacy of intraoperative radiotherapy (IORT) for women with early-stage breast cancer. The aim of this meta-analysis was to summarize the available evidence comparing the efficacy and safety of IORT with those of whole-breast external beam radiotherapy (EBRT) for women with early-stage breast cancer. MEDLINE, EMBASE, the Web of Science, and the Cochrane Library were searched up to October 2014. Two authors independently conducted the literature selection and data extraction. Studies that compared IORT with whole-breast EBRT were included in the systematic review. IORT was defined as a single dose of irradiation to the tumor bed during breast-conserving surgery rather than whole-breast irradiation. Qualities of RCTs were evaluated according to the PEDro scale. Qualities of non-RCTs were evaluated according to the Methodological Index for Non-Randomized Studies (MINORS). The risk ratios (RRs) of ipsilateral breast tumor recurrence, overall mortality, breast cancer mortality, non-breast cancer mortality, and distant metastasis were pooled using a random-effects model. Four studies with 5415 patients were included in this meta-analysis, including 2 randomized controlled trials (RCTs) and 2 non-RCTs. Ipsilateral breast tumor recurrence was significantly higher in patients with IORT compared to those with whole-breast EBRT (RR 2.83, 95% CI 1.23–6.51), but with significant heterogeneity (I2 = 58.5%, P = 0.065). Comparing IORT with whole-breast EBRT, the pooled RRs for overall mortality, breast cancer mortality, non-breast cancer mortality, and distant metastasis were 0.88 (95% CI: 0.66–1.17), 1.20 (95% CI: 0.77–1.86), 0.76 (95% CI: 0.44–1.31), and 0.95 (95% CI: 0.61–1.49), respectively. IORT had a significantly higher risk of ipsilateral breast tumor recurrence than whole-breast EBRT. Overall mortality did not differ significantly. IORT should be used in conjunction with the prudent selection of

    Triple-negative breast cancer (TNBC) is a heterogeneous disease. Possibly genetic characterisation provides the most appropriate information on tumour biology and prognosis, but it is only limitedly available in clinical practice. The aim of this investigation was to explore what additional prognostic information could be gained from detailed histomorphologic report. patients were selected retrospectively operated from 2005 to 2009 in one institution and charts were revised. Beyond age, tumour and nodal status, histologic grade and therapy, the additional pathologic characteristics were also involved in analysis: necrosis, lymphocytic infiltration, peritumoural vascular invasion (PVI), perineural invasion, DCIS extent and grade, perinodal spread, mitotic activity index (MAI). 295 early TNBC were involved. In univariate survival analysis with a mean follow-up of 3.57 years the tumour size, the nodal status, type of operation (conservation or mastectomy), irradiation, PVI and perinodal spread proved to be significantly connected with both disease free survival (DFS) and breast cancer specific overall survival (BSOS), and necrosis and chemotherapy with BSOS. Necrosis analysed together with lymphocytic infiltrate showed greater predicting power. In multivariate analysis nodal metastasis, necrosis positive/lymphacytic infiltration negative status and lack of irradiation has significant negative impact on DFS (p = <0.0001 HR:1.98 [1.4-2.77], p = <0.017 HR:2.1 [1.1-3.8], p = <0.001 HR:0.25 [0.11-0.57], respectively) and BSOS (p = <0.0001 HR:2.47 [1.8-3.4], p = <0.017 HR:3.7 [1.6-8.2], p = <0.0017 HR:0.24 [0.1-0.58], respectively). For DFS perivascular invasion also showed significant effect (p = <0.042 HR:2.5 [1.0-6.0]). Nodal status was the strongest prognostic parameter but other histomorphologic parameters can be used for prognosis prediction.

    Exclusive breast-feeding is recommended during the first 6 months of life. Use of simple indicators to predict early stopping of exclusive breast-feeding may be desirable in clinical practice. A breast-feeding assessment evaluated at discharge and including maternal age, previous breast-feeding experience, latching difficulty, and breast-feeding interval could be useful.

  19. Digital Breast Tomosynthesis: Lessons Learned from Early Clinical Implementation

    The limitations of mammography are well known and are partly related to the fact that with conventional imaging, the three-dimensional volume of the breast is imaged and presented in a two-dimensional format. Because normal breast tissue is similar in x-ray attenuation to some breast cancers, clinically relevant malignancies may be obscured by normal overlapping tissue. In addition, complex areas of normal tissue may be perceived as suspicious. The limitations of two-dimensional breast imaging lead to low sensitivity in detecting some cancers and high false-positive recall rates. Although mammographic screening has been shown to reduce breast cancer deaths by approximately 30%, controversy exists over when and how often screening mammography should occur. Digital breast tomosynthesis (DBT) is rapidly being implemented in breast imaging clinics around the world as early clinical data demonstrate that it may address some of the limitations of conventional mammography. With DBT, multiple low-dose x-ray images are acquired in an arc and reconstructed to create a three-dimensional image, thus minimizing the impact of overlapping breast tissue and improving lesion conspicuity. Early studies of screening DBT have shown decreased false-positive callback rates and increased rates of cancer detection (particularly for invasive cancers), resulting in increased sensitivity and specificity. In our clinical practice, we have completed more than 2 years of using two-view digital mammography combined with two-view DBT for all screening and select diagnostic imaging examinations (over 25,000 patients). Our experience, combined with previously published data, demonstrates that the combined use of DBT and digital mammography is associated with improved outcomes for screening and diagnostic imaging.

    Cancer has been increasingly recognized as a global issue. This is especially true in countries like China, where cancer incidence has increased likely because of changes in environment and lifestyle. However, cancer is not a modern disease; early cases have been recorded in ancient medical books in the West and in China. Here, we provide a brief history of cancer, focusing on cancer of the breast, and review the etymology of ai, the Chinese character for cancer. Notable findings from both Western and Chinese traditional medicine are presented to give an overview of the most important, early contributors to our evolving understanding of human breast cancer. We also discuss the earliest historical documents to record patients with breast cancer.

    Accredited breast centers in the United States are measured on performance of breast conservation surgery (BCS) in the majority of women with early-stage breast cancer. Prior research in regional and limited national cohorts suggests a recent shift toward increasing performance of mastectomy in patients eligible for BCS. To examine whether mastectomy rates in patients eligible for BCS are increasing over time nationwide, and are associated with coincident increases in breast reconstruction and bilateral mastectomy for unilateral disease. We performed a retrospective cohort study of temporal trends in performance of mastectomy for early-stage breast cancer using multivariable logistic regression modeling to adjust for pertinent covariates and interactions. We studied more than 1.2 million adult women treated at centers accredited by the American Cancer Society and the American College of Surgeons Commission on Cancer from January 1, 1998, to December 31, 2011, using the National Cancer Data Base. Year of breast cancer diagnosis. Proportion of women with early-stage breast cancer who underwent mastectomy. Secondary outcome measures include temporal trends in breast reconstruction and bilateral mastectomy for unilateral disease. A total of 35.5% of the study cohort underwent mastectomy. The adjusted odds of mastectomy in BCS-eligible women increased 34% during the most recent 8 years of the cohort, with an odds ratio of 1.34 (95% CI, 1.31-1.38) in 2011 relative to 2003. Rates of increase were greatest in women with clinically node-negative disease (odds ratio, 1.38; 95% CI, 1.34-1.41) and in situ disease (odds ratio, 2.05; 95% CI, 1.95-2.15). In women undergoing mastectomy, rates of breast reconstruction increased from 11.6% in 1998 to 36.4% in 2011 (P < .001 for trend). Rates of bilateral mastectomy for unilateral disease increased from 1.9% in 1998 to 11.2% in 2011 (P < .001). In the past decade, there have been marked trends toward higher proportions of BCS

  4. The role of aromatase inhibitors in early breast cancer.

    2003-04-01

    The role of hormonal therapy for the treatment of patients with early stage breast cancer has been evaluated in many studies. The results of these studies establish tamoxifen as the gold standard of hormonal therapy for the adjuvant treatment of hormone receptor-positive invasive breast cancer in pre- and postmenopausal women. Studies show tamoxifen reduces the risk of invasive breast cancer in women at increased risk for the disease, including women with ductal carcinoma in situ. Tamoxifen has adverse effects such as hot flashes, increased risk of uterine cancer in postmenopausal women, and rare occurrence of thromboembolic disease. Despite the multiple therapeutic roles of tamoxifen, alternatives are needed. Aromatase inhibitors (AI) are drugs with antiestrogenic activity. AIs function by inhibiting the peripheral conversion of adrenally synthesized androstenedione to estradiol through inhibition of the aromatase enzyme. AIs do not suppress estradiol synthesis by the ovary adequately. Therefore, AIs are effective in reducing circulating estradiol levels in postmenopausal women, but not premenopausal women. Selective nonsteroidal AIs, including anastrozole (Arimidex; AstraZeneca, Wilmington, DE) and letrozole (Femara; Novartis, East Hanover, NJ), and the steroidal AI exemestane (Aromasin; Pharmacia, Peapack, NJ) have been associated with increased specificity and improved therapeutic index compared to nonselective AIs such as aminoglutethamide. Nonsteroidal and steroidal AIs have demonstrated to be superior to megestrol acetate in second-line therapy of postmenopausal women with metastatic breast cancer, and selective nonsteroidal AIs have shown to be superior to tamoxifen in first-line therapy of postmenopausal women with metastatic breast cancer. The ATAC (Arimidex, tamoxifen, alone, or in combination) trial is the only published randomized trial comparing the efficacy of an AI to tamoxifen for the adjuvant treatment of women with early breast cancer.

    Nipple discharge (ND) can be the earliest presenting symptom of breast cancer. We hereby present two cases of breast cancer with no palpable mass manifesting as isolated ND, which was whitish in color. In both cases, cytology of the discharge revealed highly pleomorphic cells indicating a high grade malignancy. Mammography showed diffuse, extensive microcalcifications. Simple mastectomy with axillary clearance was done. Histology in both cases revealed diffusely spreading intraductal carcinoma, with focus of microinvasion in one case. ND if scanty or not blood stained is often ignored by the patients and at times, the clinicians. This article highlights that ND can be an early warning sign of intraductal carcinomas that are non-invasive in early stage. Irrespective of the color or nature of the discharge, unilateral ND needs to be evaluated. Proper clinical assessment, cytological evaluation of the ND, and mammography ought to be performed in all such cases. Considering the low level of awareness in women regarding the warning signs of breast cancer, the current focus is to create “breast awareness.” Women should be sensitized to recognize any unusual changes in their breasts and report to their health care providers at the earliest.

    The miRNAs have well studied roles in cancer. Here, we identified altered miRNA expression by global miRNA profiling in peripheral blood mononuclear cells (PBMCs) of breast cancer (n = 15) and healthy subjects (n = 15), and further validated the selected miRNAs in PBMCs (n = 45), blood plasma (n = 45) and breast tissue samples (n = 09). The expression of altered miRNAs was also evaluated in PBMCs among early stage (n = 32), advanced stage (n = 13), triple positive (n = 5) and triple negative (n = 5) breast cancer patients. Results showed differential pattern of expressions of these miRNAs in multiple cohorts, however in early stage breast cancer, miR-106a-5p and miR-454-3p were upregulated (p < 0.05), miR-195-5p and miR-495 were downregulated (p < 0.05) in PBMCs. In addition, these miRNAs were also significantly associated with cancer and ErbB signaling pathways. Multiple regression analysis and receiver-operative curve (ROC) analysis of miR-195-5p and miR-495 with area under curve (AUC) of 0.901 showed best discriminating combination for early stage breast cancer detection. In summary, the present study delineated the importance of miR-195-5p and miR-495 miRNAs as prospective circulating surrogate molecular signatures for early detection of breast cancer.

    Background: We report the results of a single-institution, phase II trial of accelerated partial breast irradiation (APBI) using a single dose of intraoperative electron radiation therapy (IOERT) in patients with low-risk early stage breast cancer. Methods and Materials: A cohort of 226 patients with low-risk, early stage breast cancer were treated with local excision and axillary management (sentinel node biopsy with or without axillary node dissection). After the surgeon temporarily reapproximated the excision cavity, a dose of 21 Gy using IOERT was delivered to the tumor bed, with a margin of 2 cm laterally. Results: With a mean follow-up of 46 months (range, 28-63 months), only 1 case of local recurrence was reported. The observed toxicity was considered acceptable. Conclusions: APBI using a single dose of IOERT can be delivered safely in women with early, low-risk breast cancer in carefully selected patients. A longer follow-up is needed to ascertain its efficacy compared to that of the current standard treatment of whole-breast irradiation.

    A series of 100 women who underwent breast reconstruction is reviewed. They had previously been treated for breast cancer with modified radical or simple mastectomy. The technique and early results of reconstruction are presented. The same surgeon performed all these operations and the technique was not varied. Emotional need for reconstruction was the main factor in patient selection. The interval between mastectomy and reconstruction was as a rule at least one year after removal of stage I cancer and 2-5 years in stage II cases. Scar correction was required significantly more often after oblique than after horizontal mastectomy incision. A submuscular pocket was created to accommodate the prosthesis and a muscle and fascia flap was used to add tissue and contour. No major early complications occurred. The submuscular implantation of prosthesis facilitated clinical follow-up. In a background population of breast cancer patients, the overall frequency of breast reconstruction was 4%. The figure for premenopausal patients with stage I breast cancer treated with modified radical mastectomy was 18%.

    The standard of care for elderly women with breast cancer remains controversial. The aim of this study was to clarify the management of elderly breast cancer patients who undergo surgery. This retrospective single-center cohort study included 2276 breast cancer patients who underwent surgery between 1993 and 2014. The patients were divided into three groups according to age: ≤64 y (young), 65-74 y (older), and ≥75 y (elderly). The elderly had more advanced stage disease at diagnosis (stage III and IV, 16.2%, 17.5%, and 22.1% for the young, older, and elderly groups, respectively). The elderly were more likely to undergo mastectomy (43.3%, 41.4%, and 50.7%, respectively), omit axillary operation (0.6%, 1.1%, and 9.3%, respectively), and skip radiotherapy after breast-conserving surgery (93.1%, 86.8%, and 29.1%, respectively). Endocrine therapy was widely used in all the groups (94.4%, 93.8%, and 90.1%, respectively), but frequency of chemotherapy was lower in the elderly regardless of hormone receptor (HR) status (40.8%, 25.5%, and 9.3% in HR(+), 87.2%, 75.3%, and 39.5% in HR(-), respectively). Although the locoregional recurrence rate was higher in the elderly (4.2%, 3.4%, and 7.0% at 5 y, respectively; P = 0.028), there were no differences among groups in distant metastasis-free survival or breast cancer-specific survival. Although elderly patients had more advanced stages of cancer and received less treatment, there were no differences in survival. Omission of axillary dissection, radiation, and chemotherapy after operation may be an option for breast cancer patients aged ≥75 y. Copyright © 2016 Elsevier Inc. All rights reserved.

    Epigenetic modifiers, including the histone deacetylase inhibitor vorinostat, may sensitize tumors to chemotherapy and enhance outcomes. We conducted a multicenter randomized phase II neo-adjuvant trial of carboplatin and nanoparticle albumin-bound paclitaxel (CP) with vorinostat or placebo in women with stage II/III, human epidermal growth factor receptor 2 (HER2)–negative breast cancer, in which we also examined whether change in maximum standardized uptake values corrected for lean body mass (SULmax) on 18F-FDG PET predicted pathologic complete response (pCR) in breast and axillary lymph nodes. Methods Participants were randomly assigned to 12 wk of preoperative carboplatin (area under the curve of 2, weekly) and nab-paclitaxel (100 mg/m2 weekly) with vorinostat (400 mg orally daily, days 1–3 of every 7-d period) or placebo. All patients underwent 18F-FDG PET and research biopsy at baseline and on cycle 1 day 15. The primary endpoint was the pCR rate. Secondary objectives included correlation of change in tumor SULmax on 18F-FDG PET by cycle 1 day 15 with pCR and correlation of baseline and change in Ki-67 with pCR. Results In an intent-to-treat analysis (n = 62), overall pCR was 27.4% (vorinostat, 25.8%; placebo, 29.0%). In a pooled analysis (n = 59), we observed a significant difference in median change in SULmax 15 d after initiating preoperative therapy between those achieving pCR versus not (percentage reduction, 63.0% vs. 32.9%; P = 0.003). Patients with 50% or greater reduction in SULmax were more likely to achieve pCR, which remained statistically significant in multivariable analysis including estrogen receptor status (odds ratio, 5.1; 95% confidence interval, 1.3–22.7; P = 0.023). Differences in baseline and change in Ki-67 were not significantly different between those achieving pCR versus not. Conclusion Preoperative CP with vorinostat or placebo is associated with similar pCR rates. Early change in SULmax on 18F-FDG PET 15 d after the

    Purpose: Accelerated partial-breast irradiation (PBI) is a new treatment paradigm for patients with early-stage breast cancer. Although PBI may lead to greater local recurrence rates, it may be cost-effective because of better tolerability and lower cost. We aim to determine the incremental cost-effectiveness of PBI compared with whole-breast radiation therapy (WBRT) for estrogen receptor-positive postmenopausal women treated for early-stage breast cancer. Methods and Materials: We developed a Markov model to describe health states in the 15 years after radiotherapy for early-stage breast cancer. External beam (EB) and MammoSite (MS) PBI were considered and assumed to be equally effective, but carried different costs. Patients received tamoxifen, but not chemotherapy. Utilities, recurrence risks, and costs were adapted from the literature; the baseline utility for no disease after radiotherapy was set at 0.92. Probabilistic sensitivity analyses were performed to model uncertainty in the PBI hazard ratio, recurrence pattern, and patient utilities. Costs (in 2004 US dollars) and quality-adjusted life-years were discounted at 3%/y. Results: The incremental cost-effectiveness ratio for WBRT compared with EB-PBI was $630,000/quality-adjusted life-year; WBRT strongly dominated MS-PBI. One-way sensitivity analysis found that results were sensitive to PBI hazard ratio, recurrence pattern, baseline recurrence risk, and no evidence of disease PBI utility values. Probabilistic sensitivity showed that EB-PBI was the most cost-effective technique over a wide range of assumptions and societal willingness-to-pay values. Conclusions: EB-PBI was the most cost-effective strategy for postmenopausal women with early-stage breast cancer. Unless the quality of life after MS-PBI proves to be superior, it is unlikely to be cost-effective.

Methods We used data on the first residence of 9,340 women born 1908–1935 in the Reykjavik Study as well as food frequency data for different periods of life from a subgroup of the cohort entering the AGES-Reykjavik Study (n = 2,882). Results During a mean follow-up of 27.3 years, 744 women were diagnosed with breast cancer in the Reykjavik Study. An inverse association of breast cancer was observed among women who lived through the puberty period in coastal villages, compared with women residing in the capital area (HR = 0.78, 95% CI: 0.61, 0.99). In the subgroup analysis of this Icelandic population, generally characterized by high fish intake, we found an indication of lower risk of breast cancer among women with high fish consumption (more than 4 portions per week) in adolescence (HR 0.71, 95% CI, 0.44, 1.13) and midlife (HR 0.46, 95% CI, 0.22, 0.97), compared with low consumers (2 portions per week or less). No association was found for fish liver oil consumption in any time period which could be due to lack of a reference group with low omega-3 fatty acids intake in the study group. Conclusion Our findings suggest that very high fish consumption in early to midlife may be associated with a reduced risk of breast cancer. Impact Very high fish consumption in early adulthood to midlife may be associated with decreased risk of breast cancer. PMID:27765796

    Limonene is a bioactive food component found in citrus peel oil that has shown chemopreventive and chemotherapeutic activities in preclinical studies. We conducted an open-label pilot clinical study to determine the human breast tissue disposition of limonene and its associated bioactivity. We recruited 43 women with newly diagnosed operable breast cancer electing to undergo surgical excision to take 2 grams of limonene daily for two to six weeks before surgery. Blood and breast tissue were collected to determine drug/metabolite concentrations and limonene-induced changes in systemic and tissue biomarkers of breast cancer risk or carcinogenesis. Limonene was found to preferentially concentrate in the breast tissue, reaching high tissue concentration (mean = 41.3 μg/g tissue), whereas the major active circulating metabolite, perillic acid, did not concentrate in the breast tissue. Limonene intervention resulted in a 22% reduction in cyclin D1 expression (P = 0.002) in tumor tissue but minimal changes in tissue Ki67 and cleaved caspase-3 expression. No significant changes in serum leptin, adiponectin, TGF-β1, insulin-like growth factor binding protein-3 (IGFBP-3), and interleukin-6 (IL-6) levels were observed following limonene intervention. There was a small but statistically significant postintervention increase in insulin-like growth factor I (IGF-I) levels. We conclude that limonene distributed extensively to human breast tissue and reduced breast tumor cyclin D1 expression that may lead to cell-cycle arrest and reduced cell proliferation. Furthermore, placebo-controlled clinical trials and translational research are warranted to establish limonene's role for breast cancer prevention or treatment.

    Blood-based early detection of breast cancer has recently gained novel momentum, as liquid biopsy diagnostics is a fast emerging field. In this study, we aimed to identify secreted proteins which are up-regulated both in tumour tissue and serum samples of breast cancer patients compared to normal tissue and sera. Based on two independent tissue cohorts (n = 75 and n = 229) and one serum cohort (n = 80) of human breast cancer and healthy serum samples, we characterised AGR3 as a novel potential biomarker both for breast cancer prognosis and early breast cancer detection from blood. AGR3 expression in breast tumours is significantly associated with oestrogen receptor α (P<0.001) and lower tumour grade (P<0.01). Interestingly, AGR3 protein expression correlates with unfavourable outcome in low (G1) and intermediate (G2) grade breast tumours (multivariate hazard ratio: 2.186, 95% CI: 1.008-4.740, P<0.05) indicating an independent prognostic impact. In sera analysed by ELISA technique, AGR3 protein concentration was significantly (P<0.001) elevated in samples from breast cancer patients (n = 40, mainly low stage tumours) compared to healthy controls (n = 40). To develop a suitable biomarker panel for early breast cancer detection, we measured AGR2 protein in human serum samples in parallel. The combined AGR3/AGR2 biomarker panel achieved a sensitivity of 64.5% and a specificity of 89.5% as shown by receiver operating characteristic (ROC) curve statistics. Thus our data clearly show the potential usability of AGR3 and AGR2 as biomarkers for blood-based early detection of human breast cancer.

    Breast-conservation surgery (BCS) is established as a safe surgical treatment for most patients with early breast cancer. Recently, advances in oncoplastic techniques are capable of preserving the breast form and quality of life. Although most BCS defects can be managed with primary closure, the aesthetic outcome may be unpredictable. Among technical options, therapeutic reduction mammaplasty (TRM) remains a useful procedure since the BCS defect can be repaired and the preoperative appearance can be improved, resulting in more proportional breasts. As a consequence of rich breast tissue vascularization, the greater part of reduction techniques have based their planning on preserving the pedicle of the nipple-areola complex after tumor removal. Reliable circulation and improvement of a conical shape to the breast are commonly described in TRM reconstructions. With an immediate approach, the surgical process is smooth since both procedures can be carried out in one operative setting. Additionally, it permits wider excision of the tumor, with a superior mean volume of the specimen and potentially reduces the incidence of margin involvement. Regardless of the fact that there is no consensus concerning the best TRM technique, the criteria is determined by the surgeon’s experience, the extent/location of glandular tissue resection and the size of the defect in relation to the size of the remaining breast. The main advantages of the technique utilized should include reproducibility, low interference with the oncological treatment and long-term results. The success of the procedure depends on patient selection, coordinated planning and careful intra-operative management. PMID:24527398

  17. Early microbial contact, the breast milk microbiome and child health.

    PubMed

    2016-02-01

    The significance of contact with microbes in early life for subsequent health has been the subject of intense research during the last 2 decades. Disturbances in the establishment of the indigenous intestinal microbiome caused by cesarean section delivery or antibiotic exposure in early life have been linked to the risk of immune-mediated and inflammatory conditions such as atopic disorders, inflammatory bowel disease and obesity later in life. Distinct microbial populations have recently been discovered at maternal sites including the amniotic cavity and breast milk, as well as meconium, which have previously been thought to be sterile. Our understanding of the impact of fetal microbial contact on health outcomes is still rudimentary. Breast milk is known to modulate immune and metabolic programming. The breast milk microbiome is hypothesized to guide infant gut colonization and is affected by maternal health status and mode of delivery. Immunomodulatory factors in breast milk interact with the maternal and infant gut microbiome and may mediate some of the health benefits associated with breastfeeding. The intimate connection between the mother and the fetus or the infant is a potential target for microbial therapeutic interventions aiming to support healthy microbial contact and protect against disease.

    Breast-feeding is a known protective factor against breast cancer. Breast-feeding duration is influenced by hormone levels, milk production, and lifestyle factors. The aims were to investigate how breast-feeding duration and milk production affected tumor characteristics and risk for early breast cancer events in primary breast cancer patients. Between 2002 and 2008, 634 breast cancer patients in Lund, Sweden, took part in an ongoing prospective cohort study. Data were extracted from questionnaires, pathology reports, and patients' charts from 592 patients without preoperative treatment. Breast-feeding duration ≤12 months of the first child was associated with higher frequency of ER+/PgR+ tumors (P=0.02). Median follow-up time was 4.9 years. Higher risk for early events was observed for breast-feeding duration of first child >12 months (LogRank P=0.001), total breast-feeding duration >12 months (LogRank P=0.008), as well as 'excessive milk production' during breast-feeding of the first child (LogRank P=0.001). Patients with 'almost no milk production' had no events. In a multivariable model including both 'excessive milk production' and breast-feeding duration of the first child >12 months, both were associated with a two-fold risk for early events, adjusted HRs 2.33 (95% CI: 1.25-4.36) and 2.39 (0.97-5.85), respectively, while total breast-feeding duration was not. 'Excessive milk production' was associated with a two-fold risk of early distant metastases, adjusted HR 2.59 (1.13-5.94), but not duration. In conclusion, 'excessive milk production' during breast-feeding was associated with higher risk for early events independent of tumor characteristics, stressing the need to consider host factors in the evaluation of prognostic markers.

    DNA methylation can mimic the effects of both germline and somatic mutations for cancer predisposition genes such as BRCA1 and p16INK4a. Constitutional DNA methylation of the BRCA1 promoter has been well described and is associated with an increased risk of early-onset breast cancers that have BRCA1-mutation associated histological features. The role of methylation in the context of other breast cancer predisposition genes has been less well studied and often with conflicting or ambiguous outcomes. We examined the role of methylation in known breast cancer susceptibility genes in breast cancer predisposition and tumor development. We applied the Infinium HumanMethylation450 Beadchip (HM450K) array to blood and tumor-derived DNA from 43 women diagnosed with breast cancer before the age of 40 years and measured the methylation profiles across promoter regions of BRCA1, BRCA2, ATM, PALB2, CDH1, TP53, FANCM, CHEK2, MLH1, MSH2, MSH6 and PMS2. Prior genetic testing had demonstrated that these women did not carry a germline mutation in BRCA1, ATM, CHEK2, PALB2, TP53, BRCA2, CDH1 or FANCM. In addition to the BRCA1 promoter region, this work identified regions with variable methylation at multiple breast cancer susceptibility genes including PALB2 and MLH1. Methylation at the region of MLH1 in these breast cancers was not associated with microsatellite instability. This work informs future studies of the role of methylation in breast cancer susceptibility gene silencing. PMID:27902704

    Introduction The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides access to breast and cervical cancer screening for low-income, uninsured, and underinsured women in all states and US territories. In Idaho, a rural state with very low breast and cervical cancer screening rates, this program is called Women’s Health Check (WHC). The program has been operating continuously since 1997 and served 4,719 enrollees in 2013. The objective of this study was to assess whether disparities existed in cause-specific survival (a net survival measure representing survival of a specified cause of death in the absence of other causes of death) between women screened by WHC and outside WHC and to determine how type of surgery or survival varies with stage at diagnosis. Methods WHC data were linked to Idaho’s central cancer registry to compare stage distribution, type of surgery, and cause-specific survival between women with WHC-linked breast cancer and a comparison group of women whose records did not link to the WHC database (nonlinked breast cancer). Results WHC-linked breast cancer was significantly more likely to be diagnosed at a later stage of disease than nonlinked breast cancer. Because of differences in stage distribution between WHC-linked and nonlinked breast cancers, overall age-standardized, cause-specific breast cancer survival proportions diverged over time, with a 5.1 percentage-point deficit in survival among WHC-linked cases at 5 years of follow-up (83.9% vs 89.0%). Differences in type of surgery and cause-specific survival were attenuated when controlling for stage. Conclusion This study suggests that disparities may exist for Idaho WHC enrollees in the timely diagnosis of breast cancer. To our knowledge, this is the first study to publish comparisons of cause-specific breast cancer survival between NBCCEDP-linked and nonlinked cases. PMID:25789497

    This paper investigates discriminating tongue features to distinguish between early stage breast cancer (BC) patients and non-breast cancer individuals through non-invasive traditional Chinese medicine (TCM) tongue diagnosis. The tongue features for 67 patients with 0 and 1 stages of BC, and 70 non-breast cancer individuals are extracted by the automatic tongue diagnosis system (ATDS). A total of nine tongue features, namely, tongue color, tongue quality, tongue fissure, tongue fur, red dot, ecchymosis, tooth mark, saliva, and tongue shape are identified for each tongue. Features extracted are further sub-divided according to the areas located, i.e., spleen-stomach, liver-gall-left, liver-gall-right, kidney, and heart-lung areas. This study focuses on deriving significant tongue features (p<0.05) to discriminate early-stage BC patients from non-breast cancer individuals. The Mann-Whitney test shows that the amount of tongue fur (p=0.024), maximum covering area of tongue fur (p=0.009), thin tongue fur (p=0.009), the average area of red dot (p=0.049), the maximum area of red dot (p=0.009), red dot in the spleen-stomach area (p=0.000), and red dot in the heart-lung area (p=0.000) demonstrate significant differences. The data collected are further classified into two groups. The training group consists of 57 early-stage BC patients and 60 non-breast cancer individuals, while the testing group is composed of 10 early-stage BC patients and 10 non-breast cancer individuals. The logistic regression by utilizing these 7 tongue features with significant differences in Mann-Whitney test as factors is performed. In order to reduce the number of tongue features employed in prediction, tongue features with the least amount of significant difference, namely, maximum area of red dot and average area of red dot, are removed progressively. The tongue features of the testing group are employed in the aforementioned three models to test the power of significant tongue features

    Preoperative anemia impacts a significant portion of breast reconstruction patients, though this does not appear to affect surgical outcomes. The impact of anemia on postoperative physical and mental health, however, is unknown. This study aimed to prospectively evaluate the role of preoperative anemia in recovery after autologous reconstruction. From 2005 to 2010, we prospectively assessed autologous breast reconstruction patients with satisfaction surveys, strength and functional tests, and the short form 36 (SF36). Data was collected preoperatively and at early (<90d), intermediate (90-365d), and late (>365d) follow-up. We stratified patients by presence or lack of preoperative anemia (hemoglobin<12 g/dL). Of 399 patients undergoing reconstruction, 179 enrolled in the study. Anemic patients (n = 31, 17%) had higher rates of preoperative chemotherapy (p = 0.02) and lower rates of radiation (p = 0.001). Preoperatively, anemic patients reported worse physical (p < 0.001), mental (p = 0.003) and overall health (p = 0.0003). These scores worsened postoperatively for anemic and nonanemic patients, though anemic patients had lower average scores in all SF36 categories. This was significant only for early follow-up physical health (p = 0.02). Change in SF36 scores and objective physical exam assessments did not differ between the two cohorts. Though preoperative anemia may not impact surgical outcomes, it adversely impacts the recovery of breast reconstruction patients. Subjective physical health differences were significant in early follow-up, though this did not translate to differences in mental health or satisfaction. We advocate for preoperative optimization of hemoglobin to enhance the early recovery potential of breast reconstruction patients.

    Breast cancer surgery is an emotive topic and rather than just simple cosmetic issues, the final appearance of the operated breast has been shown to have a significant impact on psychologic well-being and overall quality of life. Wide local excision (WLE) is a popular conservative approach to small tumors, which do not involve the nipple-areolar complex. This study compares WLE via an anterior and lateral approach. A retrospective survey of patient satisfaction was performed using a recognized and validated Body Image Score (BIS), which was sent to a total of 267 patients who had undergone WLE by either the anterior or lateral approach. The response rate was 57%, of which 89 women had undergone surgery via the anterior and 80 by the lateral approach. There was no significant difference in BIS when comparing the anterior and lateral approaches, despite concerns regarding the physical appearance of the scar and postoperative breast expressed by patients. Generally, surgery on the upper part of the breast was associated with less satisfaction than the lower, but "hiding" the scar with a lateral approach did not improve satisfaction. Surgeons should be reassured that the approach to WLE of early breast cancers has no impact on the patients overall body image and that the choice of technique should be based on the patient's personal preference and the surgeons experience and skill.

    Purpose: To determine the patterns and factors predictive of positive ipsilateral breast biopsy after conservation therapy for early-stage breast cancer. Methods and Materials: We performed a retrospective review of Stage I-II breast cancer patients initially treated with lumpectomy and radiotherapy between 1977 and 1996, who later underwent post-treatment ipsilateral breast biopsies. Results: A total of 223 biopsies were performed in 193 treated breasts: 171 single and 22 multiple biopsies. Of the 223 biopsies, 56% were positive and 44% were negative for recurrence. The positive biopsy rate (PBR) was 59% for the first and 32% for subsequent biopsies. The median time to the first post-treatment biopsy was 49 months. Of the patients with negative initial biopsy findings, 11% later developed local recurrence. The PBR was 40% among patients with physical examination findings only, 65% with mammographic abnormalities only, and 79% with both findings (p = 0.001). Analysis of the procedure type revealed a PBR of 86% for core and 58% for excisional biopsies compared with 28% for aspiration cytology alone (p = 0.025). The PBR varied inversely with age at the original diagnosis: 49% if {>=}51 years, 57% if 36-50 years, and 83% if {<=}35 years (p = 0.05). The PBR correlated directly with the interval after radiotherapy: 49% if {<=}60 months, 59% if 60.1-120 months, 77% if 120.1-180 months, and 100% if >180 months after completing postlumpectomy radiotherapy (p = 0.01). The PBR was not linked with recurrence location, initial pathologic T or N stage, estrogen receptor/progesterone receptor status, or final pathologic margins (all p {>=} 0.15). Conclusion: After definitive radiotherapy for early-stage breast cancer, a greater PBR was associated with the presence of both mammographic and clinical abnormalities, excisional or core biopsies, younger age at the initial diagnosis, and longer intervals after radiotherapy completion.

    Purpose: To compare mammographically occult (MamOcc) and mammographically positive (MamPos) early-stage breast cancer patients treated with breast-conservation therapy (BCT), to analyze differences between the two cohorts. Methods and Materials: Our two cohorts consisted of 214 MamOcc and 2168 MamPos patients treated with BCT. Chart reviews were conducted to assess mammogram reports and method of detection. All clinical-pathologic and outcome parameters were analyzed to detect differences between the two cohorts. Results: Median follow-up was 7 years. There were no differences in final margins, T stage, nodal status, estrogen/progesterone receptor status, or 'triple-negative' status. Significant differences included younger age at diagnosis (p < 0.0001), more positive family history (p = 0.0033), less HER-2+ disease (p = 0.0294), and 1{sup o} histology (p < 0.0001). At 10 years, the differences in overall survival, cause-specific survival, and distant relapse between the two groups did not differ significantly. The MamOcc cohort had more breast relapses (15% vs. 8%; p = 0.0357), but on multivariate analysis this difference was not significant (hazard ratio 1.0, 95% confidence interval 0.993-1.007, p = 0.9296). Breast relapses were mammographically occult in 32% of the MamOcc and 12% of the MamPos cohorts (p = 0.0136). Conclusions: Although our study suggests that there are clinical-pathologic variations for the MamOcc cohort vs. MamPos patients that may ultimately affect management, breast relapse after BCT was not significantly different. Breast recurrences were more often mammographically occult in the MamOcc cohort; consideration should be given to closer follow-up and alternative imaging strategies (ultrasound, breast MRI) for routine posttreatment examination. To our knowledge, this represents the largest series addressing the prognostic significance of MamOcc cancers treated with BCT.

    For early-stage breast cancers mastectomy is an aggressive form of treatment. Therefore, there is a need for new treatment strategies that can enhance the use of lumpectomy by eliminating residual cancer cells with limited side effects to reduce local recurrence. Although, various radiotherapy-based methods have been developed, residual cells are found in 20–55% of the time at the first operation. Furthermore, some current treatment methods result in poor cosmesis. For the last decade, the authors have been exploring the use of polymeric composite materials in single and multi-modal implantable biomedical devices for post-operative treatment of breast cancer. In this paper, the concept and working principles of the devices, as well as selected results from experimental and numerical investigations, are presented. The results show the potential of the biomedical implants for cancer treatment. PMID:28245288

    Young women with breast cancer face a more aggressive disease and lower survival rate compared with those who are older, thereby confronting the potential finitude of life or transitoriness at a time when they are establishing their careers, developing partnerships, and building families. Little is known about the perspectives of young women with breast cancer in how they consider issues of their own mortality. Patients with stage I to III breast cancer aged 39 years and younger who were diagnosed within the last year (N = 16) were included in this qualitative study, which was a secondary analysis of texts written during an expressive writing intervention. Thematic analysis was done by 2 researchers, who reached consensus in coding and theme identification. Nine of the 16 participants (56%) wrote about their mortality (transitoriness). Three themes (being remembered, landscape of emotions and perspectives, and omnipresence of life's finitude) and 10 subthemes were identified from the rich narrative texts. Despite early-stage diagnosis and the beginning phases of adulthood, young women with breast cancer contemplate their mortality and its potential repercussions on their loved ones and their careers. Oncology professionals need to be sensitive to these concerns and provide opportunities for discussion and/or referrals for their young patients as they grapple with such potentially overwhelming issues.

    During the last decade neoadjuvant endocrine therapy (NET) has moved from being reserved for elderly and frail non-chemotherapy candidates to a primary systemic modality in selected patients with hormone sensitive breast cancer. Neoadjuvant hormonal treatment in patients with hormone receptor positive, HER-2 negative early breast cancer is proven to be an effective and safe option; it is associated with a higher rate of breast conserving surgery (BCS), may reduce the need for adjuvant chemotherapy and enables a delay of surgery for medical or practical reasons. Clinical responses range from 13% to 100% with at least 3 months of NET. Methods of assessing response should include MRI of the breast, particularly in lobular tumours. In studies comparing tamoxifen with aromatase inhibitors (AI), AI proved to be superior in terms of tumour response and rates of BCS. Change in Ki67 is accepted as a validated endpoint for comparing endocrine neoadjuvant agents. Levels of Ki67 during treatment are more closely related to long-term prognosis than pretreatment Ki67. Neoadjuvant endocrine therapy provides a unique opportunity for studies of endocrine responsiveness and the development of new experimental drugs combined with systemic hormonal treatment.

    Purpose: The objective of study is aiming to investigate the residual tumor rate after Vacuum-assisted Breast Biopsy (VABB) for early breast cancer excision and the efficacy of mammogram and ultrasound in detecting residual tumor. Methods: Patients who underwent VABB and were confirmed with breast cancer in Sun Yat-sen University Cancer Center from 2010 to 2015 were reviewed retrospectively. The residual tumor rate determined by histological examination was calculated, and then was compared with the results estimated by mammogram and ultrasound which were performed post VABB but before subsequent surgery. Univariate and multivariate analysis (logistic regression) were carried out to identify the independent risk factors associated with residual tumor. Results: In total, 126 eligible patients with early breast cancer were recruited for this study, of whom 79 (62.7%) had residual tumor and 47 (37.3 %) underwent complete excision. The residual tumor rates for lesions < 10mm, lesions 10 to 20 mm and lesions >20mm in size were 55.0%, 68.9% and 53.1%, respectively. The complete excision rates estimated by mammogram and ultrasound were 76.5% and 73.9%, with a negative predictive value of only 46.2% and 50.6%, respectively. In the multivariate logistic regression analysis, no specific factors were found associated with risk of residual tumor (all P > 0.05). Conclusions: There was a high residual tumor rate after VABB in early breast cancer. Both mammogram and ultrasound could not effectively detect the residual tumor after VABB. PMID:28261351

    Approximately 20% of breast cancer patients harbor tumors that overexpress human epidermal growth factor receptor 2 (HER2; also known as ErbB2), a receptor tyrosine kinase that belongs to the epidermal growth factor receptor family of receptor tyrosine kinases. HER2 amplification and hyperactivation drive the growth and survival of breast cancers through the aberrant activation of proto-oncogenic signaling systems, particularly the Ras/MAP kinase and PI3K/AKT pathways. Although HER2-positive (HER2(+)) breast cancer was originally considered to be a highly aggressive form of the disease, the clinical landscape of HER2(+) breast cancers has literally been transformed by the approval of anti-HER2 agents for adjuvant and neoadjuvant settings. Indeed, pertuzumab is a novel monoclonal antibody that functions as an anti-HER2 agent by targeting the extracellular dimerization domain of the HER2 receptor; it is also the first drug to receive an accelerated approval by the US Food and Drug Administration for use in neoadjuvant settings in early-stage HER2(+) breast cancer. Here, we review the molecular and cellular factors that contribute to the pathophysiology of HER2 in breast cancer, as well as summarize the landmark preclinical and clinical findings underlying the approval and use of pertuzumab in the neoadjuvant setting. Finally, the molecular mechanisms operant in mediating resistance to anti-HER2 agents, and perhaps to pertuzumab as well, will be discussed, as will the anticipated clinical impact and future directions of pertuzumab in breast cancer patients.

    Approximately 20% of breast cancer patients harbor tumors that overexpress human epidermal growth factor receptor 2 (HER2; also known as ErbB2), a receptor tyrosine kinase that belongs to the epidermal growth factor receptor family of receptor tyrosine kinases. HER2 amplification and hyperactivation drive the growth and survival of breast cancers through the aberrant activation of proto-oncogenic signaling systems, particularly the Ras/MAP kinase and PI3K/AKT pathways.

    Shortening the duration of radiation therapy would benefit women with early breast cancer treated with breast conserving surgery. It may also improve access to radiation therapy by improving efficiency in radiation oncology departments globally. This can only happen if the shorter treatment is as effective and safe as conventional radiation therapy. This is an update of a Cochrane Review first published in 2008 and updated in 2009. To assess the effect of altered radiation fraction size for women with early breast cancer who have had breast conserving surgery. We searched the Cochrane Breast Cancer Specialised Register (23 May 2015), CENTRAL (The Cochrane Library 2015, Issue 4), MEDLINE (Jan 1996 to May 2015), EMBASE (Jan 1980 to May 2015), the WHO International Clinical Trials Registry Platform (ICTRP) search portal (June 2010 to May 2015) and ClinicalTrials.gov (16 April 2015), reference lists of articles and relevant conference proceedings. No language or publication constraints were applied. Randomised controlled trials of altered fraction size versus conventional fractionation for radiation therapy in women with early breast cancer who had undergone breast conserving surgery. Two authors performed data extraction independently, with disagreements resolved by discussion. We sought missing data from trial authors. We studied 8228 women in nine studies. Eight out of nine studies were at low or unclear risk of bias. Altered fraction size (delivering radiation therapy in larger amounts each day but over fewer days than with conventional fractionation) did not have a clinically meaningful effect on: local recurrence-free survival (Hazard Ratio (HR) 0.94, 95% CI 0.77 to 1.15, 7095 women, four studies, high-quality evidence), cosmetic outcome (Risk ratio (RR) 0.90, 95% CI 0.81 to 1.01, 2103 women, four studies, high-quality evidence) or overall survival (HR 0.91, 95% CI 0.80 to 1.03, 5685 women, three studies, high-quality evidence).

    Molecular studies suggest that acquisition of metastatic potential occurs early in the development of breast cancer; mechanisms by which cells disseminate from the primary carcinomas and successfully colonize foreign tissues are, however, largely unknown. Thus, we examined levels and patterns of chromosomal alterations in primary breast tumors from node-negative (n = 114) and node-positive (n = 115) patients to determine whether specific genomic changes are associated with tumor metastasis. Fifty-two genetic markers representing 26 chromosomal regions commonly altered in breast cancer were examined in laser microdissected tumor samples to assess levels and patterns of allelic imbalance (AI). Real time-PCR (RT-PCR) was performed to determine expression levels of candidate genes. Data was analyzed using exact unconditional and Student's t-tests with significance values of P < 0.05 and P < 0.002 used for the clinicopathological and genomic analyses, respectively. Overall levels of AI in primary breast tumors from node-negative (20.8%) and node-positive (21.9%) patients did not differ significantly (P = 0.291). When data were examined by chromosomal region, only chromosome 8q24 showed significantly higher levels (P < 0.0005) of AI in node-positive primary tumors (23%) versus node-negative samples (6%). c-MYC showed significantly higher levels of gene expression in primary breast tumors from patients with lymph node metastasis. Higher frequencies of AI at chromosome 8q24 in patients with positive lymph nodes suggest that genetic changes in this region are important to the process of metastasis. Because overexpression of c-MYC has been associated with cellular dissemination as well as development of the premetastatic niche, alterations of the 8q24 region, including c-MYC, may be key determinants in the development of lymph node metastasis.

    Death in the absence of disease recurrence (competing mortality) is an important determinant of disease-free survival (DFS) in early breast cancer. The authors sought to identify predictors of this event using competing risks modeling. A cohort study was made of 1231 consecutive women with stage I to II invasive breast cancer diagnosed between 1986 and 2004, treated with breast conservation therapy. Median follow-up was 82 months. The authors used a parametric competing risks regression model to analyze factors associated with the cumulative incidence of competing mortality. They generated a risk score from the model coefficient estimates and stratified patients according to low and high risk score for analysis. Ten-year DFS was 69.7% (95% confidence interval [CI], 66.2%-72.9%). The 10-year cumulative incidence of locoregional recurrence (LRR) was 4.4% (95% CI, 3.0%-5.8%), distant recurrence was 7.1% (95% CI, 5.4%-8.9%), and competing mortality was 18.7% (95% CI, 15.9%-21.6%). On multivariate analysis, competing mortality was associated with increasing age (hazard ratio [HR], 1.83 per 10 years; 95% CI, 1.58-2.12), black race (HR, 1.71; 95% CI, 1.17-2.51), and comorbid disease (HR, 1.93, 95% CI, 1.40-2.65). Ten-year cumulative incidences of competing mortality, locoregional recurrence, and distant recurrence for patients at low (n=638) versus high (n=593) risk of competing mortality were 7.2% versus 30.6% (P<.001), 4.4% versus 4.4% (P=.97), and 8.6% versus 5.6% (P=.12), respectively. Competing mortality is an important event influencing 10-year DFS in early breast cancer and is associated with increasing age, black race, and comorbid disease. Stratifying patients according to competing mortality risk may be useful in designing clinical trials. Copyright © 2010 American Cancer Society.

    Breast cancer is the most common cancer of women in Kenya. There are no national breast cancer early diagnosis programs in Kenya. The objective was to conduct a pilot breast cancer awareness and diagnosis program at three different types of facilities in Kenya. This program was conducted at a not-for-profit private hospital, a faith-based public hospital, and a government public referral hospital. Women aged 15 years and older were invited. Demographic, risk factor, knowledge, attitudes, and screening practice data were collected. Breast health information was delivered, and clinical breast examinations (CBEs) were performed. When appropriate, ultrasound imaging, fine-needle aspirate (FNA) diagnoses, core biopsies, and onward referrals were provided. A total of 1,094 women were enrolled in the three breast camps. Of those, 56% knew the symptoms and signs of breast cancer, 44% knew how breast cancer was diagnosed, 37% performed regular breast self-exams, and 7% had a mammogram or breast ultrasound in the past year. Of the 1,094 women enrolled, 246 (23%) had previously noticed a lump in their breast. A total of 157 participants (14%) had abnormal CBEs, of whom 111 had ultrasound exams, 65 had FNAs, and 18 had core biopsies.

    Purpose: In women with favorable early breast cancer treated by lumpectomy plus tamoxifen or anastrazole, it remains unclear whether whole breast radiotherapy is beneficial. Methods and Material: Between January 1996 and June 2004, the Austrian Breast and Colorectal Cancer Study Group (ABCSG) randomly assigned 869 women to receive breast radiotherapy {+-} boost (n 414) or not (n = 417) after breast-conserving surgery (ABCSG Study 8A). Favorable early breast cancer was specified as tumor size <3 cm, Grading 1 or 2, negative lymph nodes, positive estrogen and/or progesterone receptor status, and manageable by breast-conserving surgery. Breast radiotherapy was performed after lumpectomy with 2 tangential opposed breast fields with mean 50 Gy, plus boost in 71% of patients with mean 10 Gy, in a median of 6 weeks. The primary endpoint was local relapse-free survival; further endpoints were contralateral breast cancer, distant metastases, and disease-free and overall survival. The median follow-up was 53.8 months. Results: The mean age was 66 years. Overall, there were 21 local relapses, with 2 relapses in the radiotherapy group (5-y rate 0.4%) vs. 19 in the no-radiotherapy group (5.1%), respectively (p = 0.0001, hazard ratio 10.2). Overall relapses occurred in 30 patients, with 7 events in the radiotherapy group (5-y rate 2.1%) vs. 23 events in the no-radiotherapy group (6.1%) (p = 0.002, hazard ratio 3.5). No significant differences were found for distant metastases and overall survival. Conclusion: Breast radiotherapy {+-} boost in women with favorable early breast cancer after lumpectomy combined with tamoxifen/anastrazole leads to a significant reduction in local and overall relapse.

    Despite advances in cancer therapy, treating cancer after it has metastasized remains an unmet clinical challenge. In this study we demonstrate that 100 nm liposomes target triple-negative murine breast-cancer metastases post intravenous administration. Metastatic breast cancer was induced in BALB/c mice either experimentally, by a tail vein injection of 4T1 cells, or spontaneously, after implanting a primary tumor xenograft. To track their biodistribution in vivo the liposomes were labeled with multi-modal diagnostic agents, including indocyanine green and rhodamine for whole-animal fluorescent imaging, gadolinium for magnetic resonance imaging (MRI), and europium for a quantitative biodistribution analysis. The accumulation of liposomes in the metastases peaked at 24 h post the intravenous administration, similar to the time they peaked in the primary tumor. The efficiency of liposomal targeting to the metastatic tissue exceeded that of a non-liposomal agent by 4.5-fold. Liposomes were detected at very early stages in the metastatic progression, including metastatic lesions smaller than 2 mm in diameter. Surprisingly, while nanoparticles target breast cancer metastasis, they may also be found in elevated levels in the pre-metastatic niche, several days before metastases are visualized by MRI or histologically in the tissue. This study highlights the promise of diagnostic and therapeutic nanoparticles for treating metastatic cancer, possibly even for preventing the onset of the metastatic dissemination by targeting the pre-metastatic niche.

    The Microwave Anisotropy Probe (MAP), a follow-on to the Differential Microwave Radiometer (DMR) instrument on the Cosmic Background Explorer (COBE), was launched from the Kennedy Space Center at 19:46:46 UTC on June 30, 2001. The powered flight and separation from the Delta II appeared to go as designed, with the launch placing MAP well within sigma launch dispersion and with less than 7 Nms of tip-off momentum. Because of this relatively low momentum, MAP was able to acquire the sun within only 15 minutes with a battery state of charge of 94%. After MAP's successful launch, a six week period of in-orbit checkout and orbit maneuvers followed. The dual purpose of the in-orbit checkout period was to validate the correct performance of all of MAP's systems and, from the attitude control system (ACS) point of view, to calibrate the performance of the spacecraft ACS sensors and actuators to maximize system performance. In addition to the checkout activities performed by the MAP team, the other critical activity taking place during the first six weeks after launch were a series of orbit maneuvers necessary to get the spacecraft from its launch orbit out to its desired orbit about L2, the second Earth-Sun Lagrange point. As MAP continues its standard operations, its ACS design is meeting all of its requirements to successfully complete the mission. This paper will describe the launch and early operations summarized above in greater detail, and show the performance of the attitude control and attitude determination system versus its requirements. Additionally, some of the unexpected events that occurred during this period will be discussed, including two events which dropped the spacecraft into its Safehold Mode and the presence of an "anomalous force" observed during each of the perigee orbit maneuvers that had the potential to cause these critical maneuvers to be prematurely aborted.

    The aim of this study was to evaluate local control, survival and toxicity profile of a consecutive cohort of early-stage breast cancer (EBC) patients treated with adjuvant hypofractionated radiotherapy (HF) with no boost delivered to the lumpectomy cavity, after breast-conserving surgery (BCS). Between 2005 and 2015, a total of 493 women affected with EBC were treated with HF (46 Gy/20 fractions or 40.05 Gy/15 fractions) to the whole breast without boost to tumor bed, because of age and/or favorable tumor characteristics. The primary endpoint was 5-year actuarial local control (LC); secondary endpoints included survival, toxicity profile and cosmesis. Median follow-up was 57 months (range 6-124). Actuarial 5-year overall, cancer-specific, disease-free survival and LC were 96.3, 98.9, 97.8 and 98.6 %, respectively. On multivariate analysis, tumor stage (T1 vs. T2) and hormonal status (positive vs. negative estrogen receptors) were significantly correlated with LC. Only 2 % of patients experienced ≥G3 acute skin toxicity. Late toxicity was mild with only 1 case of G3 fibrosis. Most of the patients (95 %) had good-excellent cosmetic results. HF to the whole breast with no boost delivered to the tumor bed is a safe and effective option for a population of low-risk breast cancer patients after BCS, with excellent 5-year LC, mild toxicity profile and promising cosmetic outcome. A subgroup of patients with larger tumors and/or with no estrogen receptor expression may potentially benefit from treatment intensification with a boost dose to the lumpectomy cavity.

    Purpose The purpose of this study was to identify a more suitable boost plan for simultaneously integrated boost scheme in patients with breast cancer by comparing among 3 types of whole-breast irradiation plus tumor bed boost plans. Methods Twenty patients who received radiotherapy following breast-conserving surgery for early breast cancer were enrolled in this study. We performed 1 type of electron plan (E1P plan) and 2 types of 3-dimensional conformal plans using a photon (P3P and P5P plans). The dosimetric parameters for the heart, total lung and the target volume between the 3 treatment types were compared. Results For the tumor bed, the difference in the mean dose between the 3 plans was maximally 0.1 Gy. For normal breast parenchyma, the difference in the mean dose between the 3 plans was maximally 1.1 Gy. In the dose range over the prescribed dose of 51 Gy, V55 and V60 in the E1P plan were lower than those in the P3P and P5P plans, which indicated that the E1P plan was more suitable than the P3P and P5P plans. In case of the heart and total lung, the values of clinically important parameters were slightly higher in the E1P plan than in the P3P and P5P plans. However, these differences were less than 2%. Conclusion We observed that a simple electron plan for tumor bed boost is preferable over multi-field photon plans in terms of the target volume coverage and normal tissue sparing. PMID:28273157

    Early reconstruction after mastectomy for breast cancer with definitive implants has been widely used, especially with the evolution of conservative surgical breast cancer treatments. We aimed to identify different characteristics associated with plastic surgery, based on immediate or delayed reconstruction time and evaluate quality of life in patients undergoing mastectomy for cancer. This is a cross-sectional analytical study that evaluated adult patients undergoing mastectomy for breast cancer and breast reconstruction in Plastic Surgery Service at a tertiary hospital. Between March 2011 and November 2015, 58 patients who underwent mastectomy were included, with a mean age of 51.6±10.6 years and 98.3% of them being women. Eighty percent of the patients underwent a radical mastectomy and 20% underwent segmentectomies. Immediate and delayed surgical reconstructions occurred in 22.4% and 77.6% of the cases, respectively, including immediate reconstruction with the local flap trade (15.5%), immediate reconstruction with prosthesis (6.9%), transverse rectus abdominis myocutaneous (TRAM) flap (6.9%), delayed reconstruction with local flap (8.6%), expander and prosthesis (35.7%), and reconstruction with latissimus dorsi flap and prosthesis (22.4%). When comparing subjects undergoing reconstructive surgery based on timing of reconstruction, it was observed that patients undergoing delayed breast reconstruction surgery presented a higher proportion of radical mastectomy (90.7% vs. 41.7%; P=0.001) and the need for two or more surgical interventions (64.1% vs. 20.0%; P=0.029). There was no difference in the quality of life according to reconstruction time. The characteristics associated with postmastectomy reconstruction timing are related to preoperative factors such as the procedure employed and the number of interventions performed and have no influence on complications or the quality of life.

    To explore why women in Ghana initiate breast-feeding early or late, who gives advice about initiation and what foods or fluids are given to babies when breast-feeding initiation is late. Qualitative data were collected through 52 semistructured interviews with recent mothers, 8 focus group discussions with women of child-bearing age and 13 semistructured interviews with health workers, policy makers and implementers. The major reasons for delaying initiation of breast-feeding were the perception of a lack of breast milk, performing postbirth activities such as bathing, perception that the mother and the baby need rest after birth and the baby not crying for milk. Facilitating factors for early initiation included delivery in a health facility, where the staff encouraged early breast-feeding, and the belief in some ethnic groups that putting the baby to the breast encourages the milk. Policy makers tended to focus on exclusive breast-feeding rather than early initiation. Most activities for the promotion of early initiation of breast-feeding were focused on health facilities with very few community activities. It is important to raise awareness about early initiation of breast-feeding in communities and in the policy arena. Interventions should focus on addressing barriers to early initiation and should include a community component.

    Summary Background The purpose of this study was to evaluate the usefulness of galactography (GL) in the early diagnosis of breast cancer in patients with pathologic nipple discharge (PND). Patients and Methods We retrospectively studied all galactograms obtained in 117 women with PND, who subsequently had a biopsy. The findings detected in the galactograms of the patients in this study were assigned to different categories of the Galactogram Image Classification System (GICS): GICS 2, benign; GICS 3, probably benign; GICS 4, suspicious for malignancy; and GICS 5, highly suspicious for malignancy. Results The galactograms were classified into GICS 2 (29 cases; 24.7%), GICS 3 (42 cases; 35.8%), GICS 4 (30 cases; 25.6%), and GICS 5 (16 cases; 13.6%). A good correlation was observed between histological diagnosis and GICS categories (p < 0.05). All cases diagnosed with carcinoma (n = 18) were classified in GICS categories 4–5: ductal carcinoma in situ in 14 cases (11.9%) and invasive carcinoma in 4 cases (3.4%). Conclusion GL is a useful procedure in the early diagnosis of breast cancer in patients with PND. PMID:24419050

    To evaluate the effectiveness of intra-operative radiotherapy (IORT) in breast cancer in terms of local control, esthetic results and disease-free survival. From June 2007 to October 2011, 110 patients with early-stage breast cancer were submitted to quadrantectomy and IORT. A total dose of 21 Gy prescribed at 90-100% isodose was delivered in all cases. Patients were evaluated after surgery for early and late complications. Median follow-up was 27 (range: 2-54) months. In 10 patients (9.1%), breast ultrasound showed liponecrosis. Six patients (5.5%) developed grade 2 fibrosis. Disease-free survival rates at 2 and 3 years were 96.8% and 92.9 %. Three patients (2.7%) developed local recurrence, two patients (1.8%) distant metastasis. Two patients died. The 2- and 3-year overall survival rates were 100% and 97.3%, respectively. IORT could be an appropriate therapeutic alternative in selected patients although it remains investigational; longer follow-up to confirm these results is required.

    The aim of the present study was to explore cell biological characteristics of normal breast, benign proliferative breast diseases and noninvasive breast malignancies based on the recently published adult progenitor cell concept from our group. Here, we investigated the proliferative activity of CK5/14(+), CK8/18/19(+) and alpha-smooth muscle actin(+) cellular phenotypes encountered in normal mammary gland, in a series of usual ductal hyperplasias and early malignant breast diseases, such as atypical ductal and lobular hyperplasias, as well as ductal and lobular in situ carcinomas. Immunohistochemical double labeling was performed on frozen sections from diagnostic breast biopsies by using antibodies to basal cytokeratins (CK5/14), glandular cytokeratins (CK8/18/19), smooth muscle actin and the Ki-67 antigen (MIB1). Normal breast tissues and usual ductal hyperplasias were characterized by a heterogeneous cellular composition of the growth fraction. The proliferative cell compartment consisted of CK8/18/19(+) glandular and, in a variable proportion, CK5/14(+) progenitor phenotypes. In contrast, noninvasive breast malignancies were composed of a monotonous proliferation of CK 8/18/19(+) neoplastic glandular cells. These findings indicate a significant role of progenitor cells in the development of benign proliferative breast diseases and lend support to the view that malignant transformation in the human breast usually occurs in a cell committed to the glandular lineage. Our results provide cell kinetic support to the functional progenitor cell hypothesis, and we propose this concept as an operative model for understanding benign proliferative and malignant breast diseases.

    Purpose To investigate the diagnostic performance and tissue changes in early (1 year or less) breast magnetic resonance (MR) imaging surveillance in women who underwent breast conservation therapy for breast cancer. Materials and Methods This prospective study was approved by the institutional review board, and written informed consent was obtained. Between April 2014 and June 2016, 414 women (mean age, 51.5 years; range, 21-81 years) who underwent 422 early surveillance breast MR imaging examinations (median, 6.0 months; range, 2-12 months) after breast conservation therapy were studied. The cancer detection rate, positive predictive value of biopsy, sensitivity, specificity, accuracy, and area under the curve of surveillance MR imaging, mammography, and ultrasonography (US) were assessed. Follow-up was also obtained in 95 women by using positron emission tomography (PET)/computed tomography (CT). Background parenchymal enhancement (BPE) changes in the contralateral breast were assessed according to adjuvant therapy by using the McNemar test. Results Of 11 detected cancers, six were seen at MR imaging only, one was seen at MR imaging and mammography, two were seen at MR imaging and US, one was seen at mammography only, and one was seen at PET/CT only. Three MR imaging-depicted cancers were observed at the original tumor bed, and two MR imaging-depicted cancers were observed adjacent to the original tumor. Among two false-negative MR imaging diagnoses (two cases of ductal carcinoma in situ), one cancer had manifested as calcifications at mammography without differentiated enhancement at MR imaging, and the other cancer was detected at PET/CT, but MR imaging results were negative because of marked BPE, which resulted in focal lesion masking. The positive predictive value of biopsy and the sensitivity, specificity, accuracy, and area under the curve for MR imaging were 32.1% (nine of 28), 81.8% (nine of 11), 95.1% (391 of 411), 94.7% (400 of 422), and 0

    Background After treatment for early-stage breast cancer (bca), annual surveillance mammography (asm) is recommended based on the assumption that early detection of an invasive ipsilateral breast tumour recurrence or subsequent invasive contralateral primary bca reduces bca mortality. Methods We studied women with unilateral early-stage bca treated by breast-conserving surgery from 1994 to 1997 who subsequently developed an ipsilateral recurrence or contralateral primary more than 24 months after initial diagnosis, without prior regional or distant metastases. Annual surveillance mammography was defined as 2 episodes of bilateral mammography 11–18 months apart during the 2 years preceding the ipsilateral recurrence or contralateral primary. The association between asm and bca death was evaluated using a Cox proportional hazards model. Results We identified 669 women who experienced invasive ipsilateral recurrence (n = 455) or a contralateral primary (n = 214) at a median interval of 53 months [interquartile range (iqr): 37–72 months] after initial diagnosis, 64.7% of whom had received asm during the preceding 2 years. The median interval between the 2 bilateral mammograms was 12.3 months (iqr: 11.9–13.0 months), and the median interval between the 2nd mammogram and histopathologic confirmation of ipsilateral recurrence or contralateral primary was 1.5 months (iqr: 0.8–3.9 months). Median followup after ipsilateral recurrence or contralateral primary was 7.76 years (iqr: 3.68–9.81 years). The adjusted hazard ratio for bca death associated with asm was 0.86 (95% confidence limits: 0.63, 1.16). Conclusions Annual surveillance mammography was associated with a modestly lowered hazard ratio for bca death. PMID:28050142

    The aim of the study was to evaluate dynamic contrast-enhanced breast magnetic resonance imaging (DCE-MRI) features for the prediction of early and late recurrences in patients with breast cancer.Of 1030 breast cancer patients who underwent surgery at our hospital from January 2007 to July 2011, 83 recurrent breast cancer patients were enrolled in this study. We compared MRI features (background parenchymal enhancement [BPE], internal enhancement, adjacent vessel sign, whole-breast vascularity, initial enhancement pattern, kinetic curve types, and quantitative kinetic parameters) and clinico-pathologic variables (age, stage, histologic grade, nuclear grade, existence of lymphovascular invasion and extensive intraductal carcinoma component, and immunohistochemical profiles) between patients with early (≤2.5 years after surgery) and late recurrence (>2.5 years after surgery). Cox proportional hazard regression analysis was performed to evaluate independent risk factors for early and late recurrence.On breast MRI, prominent ipsilateral whole-breast vascularity was independently associated with early recurrence (hazard ratio [HR], 2.86; 95% confidence intervals [CI], 1.39-5.88) and moderate or marked BPE (HR, 2.08; 95% CI, 1.04-4.18) and rim enhancement (HR, 2.14; 95% CI, 1.00-4.59) were independently associated with late recurrence. Clinico-pathologic variables independently associated with early recurrence included negative estrogen receptor (HR, 0.53; 95% CI, 0.29-0.96), whereas T2 stage (HR, 2.08; 95% CI, 1.04-4.16) and nuclear grade III (HR, 2.54; 95% CI, 1.29-4.98) were associated with late recurrence.In DCE-MRI, prominent ipsilateral whole-breast vascularity, moderate or marked BPE, and rim enhancement could be useful for predicting recurrence timing in patients with breast cancer.

    Many women in Kenya with breast cancer symptoms do not seek medical attention until their cancer is very advanced, leading to high mortality rates and a heavy cancer burden on the nation. In this study we employed eight focus groups with low- and middle-income rural and urban Kenyan women to explore their knowledge, attitudes, and behaviors concerning breast cancer and its early detection measures. Topics for discussion were derived from the components of the Health Belief Model (HBM). Findings revealed a huge divide between urban middle-income women and all other groups with respect to knowledge of breast cancer and early detection measures. In addition, women viewed breast cancer as a highly severe disease. Perceived benefits of early detection measures centered around preparing themselves for what was assumed to be inevitable death.

    Pregnancy at early, but not late age, has a strong and life-long protective effect against breast cancer. The expected overall increase in breast cancer incidence demands the development of a pharmaceutical mimicry of early-age pregnancy-mediated protection. Recently, converging results from rodent models and women on molecular and cellular mechanisms underlying the protective effect of early-age pregnancy have opened the door for translational studies on pharmacologic prevention against breast cancer. In particular, alterations in Wnt and TGFβ signaling in mammary stem/progenitor cells reveal new potential targets for preventive interventions, and thus might help to significantly reduce the incidence of breast cancer in the future. ©2015 American Association for Cancer Research.

    Objective Lymphedema is a chronic major complication that is seen frequently post-operatively and has negative effects on quality of life. In our study, determining the early-stage postoperative lymphedema frequency and specifying the risk factors in its development has been aimed. Materials and Methods One hundred one cases that were operated on for breast cancer were evaluated regarding the 12-month control of their clinical specifications, histopathological specifications, and specifications related with the surgical intervention retrospectively. The data related to the parameters envisioned as risk factors were evaluated. Results Lymphedema development was found in 7 (6.9%) out of 101 cases constituting the study group. No significant difference (p>0.05) in terms of lymphedema development was determined among age, body mass index (BMI), chemotherapy (CT), postoperative seroma or infection, mastectomy with the dominant arm, and breast-conserving surgery (BCS), which were evaluated as risk factors. There was a significance (p<0.05) between the other risk factors, which were axillary dissection (AD), number of positive lymph nodes (LN), radiotherapy (RT), the tumor size (T), and lymphedema existence. In every case in which lymphedema was determined, it was seen that there was axillary LN involvement and 15≤LN were ablated in the dissection (p<0.05). Conclusion It is seen that AD, RT applied to the breast cancer patients, and T are important risk factors in early-stage lymphedema development. No early-stage lymphedema development was determined in any of the patients to whom sentinel lymph node dissection (SLND) was applied.

    The aim of the present study was to investigate the therapeutic outcome of early-stage breast cancer (pT1aN0M0) and to identify prognostic factors for secondary primary contralateral breast cancer (CBC). A total of 85 patients with mammary carcinomas were included. All patients had undergone breast surgery and adjuvant treatment between January 2001 and December 2008 at the Central Hospital of Grenoble University (Grenoble, France). The primary end-points were disease-free survival and secondary CBC, and the potential prognostic factors were investigated. During a median follow-up of 60 months, 10 of the 85 patients presented with secondary primary cancer, of which six suffered with CBC. No patient mortalities were reported. The rates of CBC were 2.35, 3.53 and 7.06% at one, two and five years, respectively. The cumulative univariate analysis showed that microinvasion and family history are potential risk factors for newly CBC. The current study also demonstrated that secondary CBC was more likely to occur in patients with microinvasion or a family history of hte dise. In addition, the systematic treatment of secondary CBC should include hormone therapy. PMID:25435968

    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 clinical value of indocyanine green (ICG) for the fluorescence-guided detection of sentinel lymph nodes (SLNs) during sentinel lymph node biopsy (SLNB) in patients with early breast cancer. Methods This retrospective study included female patients with breast cancer. Patients were administered methylene blue and ICG using standard techniques. All SLNs that were collected during surgery were submitted for pathological examination. SLNs were defined as those that were either fluorescent, blue, fluorescent and blue or palpably suspicious. Surgical complications, axillary recurrence, distant metastasis and overall survival rates were observed postoperatively. Results A total of 60 patients were enrolled in the study. The fluorescence detection rate of SLNs was 100% ( n = 177), with a mean of 2.95 SLNs per patient. The methylene blue staining rate was 88.3% ( n = 106), with a mean of 1.77 SLNs per patient. Pathological assessment of intraoperative frozen specimens revealed SLN metastases in 10 patients, who immediately underwent axillary lymph node dissection. No patient had axillary recurrence or distant metastases, with a survival rate of 100%. Patients who underwent SLNB showed good appearance in the axillary wound, with no limited shoulder joint abduction and upper limb oedema. Conclusion Fluorescence-guided SLNB has several advantages and is suitable for clinical application.

    The role of axillary surgery for the treatment of primary breast cancer is in a process of constant change. During the last decade, axillary dissection with removal of at least 10 lymph nodes (ALD) was replaced by sentinel lymph node biopsy (SLNB) as a staging procedure. Since then, the indication for SLNB rapidly expanded. Today's surgical strategies aim to minimize the rate of patients with a negative axillary status who undergo ALD. For some subgroups of patients, the indication for SLNB (e.g. multicentric disease, large tumors) or its implication for treatment planning (micrometastatic involvement, neoadjuvant chemotherapy) is being discussed. Although the indication for ALD is almost entirely restricted to patients with positive axillary lymph nodes today, the therapeutic effect of completion ALD is more and more questioned. On the other hand, the diagnostic value of ALD in node-positive patients is discussed. This article reflects today's standards in axillary surgery and discusses open issues on the diagnostic and therapeutic role of SLNB and ALD in the treatment of early breast cancer.

    Breast cancer is the most common type of cancer in women throughout the world. However, in comparison with Western women, it presents relatively early in women of Asian ethnicity. Early menarche, late menopause, use of OCP's, family history of benign or malignant breast disease, exposure to radiation and BMI in the under-weight range are well known risk factors for the development of breast cancer in premenopausal women. Early detection with the use of breast self-examination (BSE) and breast cancer screening programs can lead to a reduction in the mortality rates due to breast cancer. The aim of our study was to assess the risk factors for breast cancer among young women and to emphasize the importance of early screening among them. We conducted a cross-sectional study among women aged 18 to 25 using a self- administered questionnaire. Data was collected over a period of 6 months from June to December, 2014. A total of 300 young women selected randomly from Dow Medical College and various departments of Karachi University successfully completed the survey. Respondents were 18-25 years of age (mean age=21.5). Out of the 300 young females, 90 (30%) had at least one risk factor, 90 (30%) had two, 40 (13%) had three, 8 (2.7%) had four, 2 (0.7%) had five while one female was found to have six positive risk factors for breast cancer. Some 66 women (22%) experienced symptoms of breast cancer such as non-cyclical pain and lumps. While 222 women (74%) had never performed breast self-examination, 22 (7.3%) had had a breast examination done by a health professional while 32 (10.7%) had participated in breast screening programs. A total of 223 (74.3%) women considered breast cancer screening important for young women. The percentage of young women with risk factors for breast cancer was found to be alarmingly high. Therefore, screening for breast cancer should start at an early age especially in high risk groups. Awareness about breast self-examination should be emphasized

    Background: This study was aimed at investigating clinical and histopathologic features of ipsilateral breast tumor recurrences (IBTR) and their effects on survival after breast conservation therapy. Methods: 1,400 patients who were treated between 1998 and 2007 and had breast-conserving surgery (BCS) for early breast cancer (cT1-2/N0-1/M0) were evaluated. Demographic and pathologic parameters, radiologic data, treatment, and follow-up related features of the patients were recorded. Results: 53 patients (3.8%) had IBTR after BCS within a median follow-up of 70 months. The mean age was 45.7 years (range, 27-87 years), and 22 patients (41.5%) were younger than 40 years. 33 patients (62.3%) had true recurrence (TR) and 20 were classified as new primary (NP). The median time to recurrence was shorter in TR group than in NP group (37.0 (6-216) and 47.5 (11-192) months respectively; p = 0.338). Progesterone receptor positivity was significantly higher in the NP group (p = 0.005). The overall 5-year survival rate in the NP group (95.0%) was significantly higher than that of the TR group (74.7%, p < 0.033). Multivariate analysis showed that younger age (<40 years), large tumor size (>20 mm), high grade tumor and triple-negative molecular phenotype along with developing TR negatively affected overall survival (hazard ratios were 4.2 (CI 0.98-22.76), 4.6 (CI 1.07-13.03), 4.0 (CI 0.68-46.10), 6.5 (CI 0.03-0.68), and 6.5 (CI 0.02- 0.80) respectively, p < 0.05). Conclusions: Most of the local recurrences after BCS in our study were true recurrences, which resulted in a poorer outcome as compared to new primary tumors. Moreover, younger age (<40), large tumor size (>2 cm), high grade, triple negative phenotype, and having true recurrence were identified as independent prognostic factors with a negative impact on overall survival in this dataset of patients with recurrent breast cancer.

    Zanoon, T. F.; Abdullah, M. Z.

    2011-11-01

    The interest in the use of ultra-wide band (UWB) impulses for medical imaging, particularly early stage breast cancer detection, is driven by safety advantage, super resolution capability, significant dielectric contrast between tumours and their surrounding tissues, patient convenience and low operating costs. However, inversion algorithms leading to recovery of the dielectric profile are complex in their nature, and vulnerable to noisy experimental conditions and environment. In this paper, we present a simplified yet robust gradient-based iterative image reconstruction technique to solve the nonlinear inverse scattering problem. The calculation is based on the Polak-Ribière's approach while the Broyden's formula is used to update the gradient in an iterative scheme. To validate this approach, both numerical and experimental results are presented. Animal derived biological targets in the form of chicken skin, beef and salted butter are used to construct an experimental breast phantom, while vegetable oil is used as a background media. UWB transceivers in the form of biconical antennas contour the breast forming a full view scanning geometry at a frequency range of 0-5 GHz. Results indicate the feasibility of experimental detection of millimetre scaled targets.

    2016-01-01

    Aim: Aberrant epigenetic events are important contributors to the pathogenesis of different types of cancers and dietary botanicals with epigenetic properties can influence early cancer development leading to cancer prevention effects. We sought to investigate potential combinatorial effects of bioactive dietary components including green tea polyphenols (GTPs) and broccoli sprouts (BSp) on neutralizing epigenetic aberrations during breast tumorigenesis. Materials & methods: The combinatorial effects were evaluated in a breast cancer transformation cellular system and breast cancer mouse xenografts. Results & conclusion: Combined treatment with epigallocatechin-3-gallate in GTPs and sulforaphane in BSp resulted in a synergistic inhibition of breast cancer cellular growth. Further studies revealed this combination led to genome-wide epigenetic alterations. Combinatorial diets significantly inhibited tumor growth in breast cancer mouse xenografts. Collectively, these studies indicate that combined GTPs and BSp are highly effective in inhibiting early breast cancer development by, at least in part, regulating epigenetic mechanisms.

    Background: The race-specific impact of prognostic variables for early breast cancer is unknown for black patients undergoing breast conservation. Methods and Materials: This was a retrospective study of 1,231 consecutive patients {>=}40 years of age with Stage I-II invasive breast cancer treated with lumpectomy and radiation therapy at the University of Chicago Hospitals and affiliates between 1986 and 2004. Patients were classified as either black or nonblack. Cox proportional hazards regression was used to model the effects of known prognostic factors and interactions with race. Results: Median follow-up for surviving patients was 82 months. Thirty-four percent of patients were black, and 66% were nonblack (Caucasian, Hispanic, and Asian). Black patients had a poorer 10-year overall survival (64.6% vs. 80.8%; adjusted hazard ratio [HR], 1.59; 95% confidence interval [CI], 1.23-2.06) and 10-year disease-free survival (58.1% vs. 75.4%; HR 1.49; 95% CI, 1.18-1.89) compared with nonblack patients. Tumor sizes were similar between nonblack and black patients with mammographically detected tumors (1.29 cm vs. 1.20 cm, p = 0.20, respectively). Tumor size was significantly associated with overall survival (HR 1.48; 95% CI, 1.12-1.96) in black patients with mammographically detected tumors but not in nonblack patients (HR 1.09; 95% CI, 0.78-1.53), suggesting that survival in black patients depends more strongly on tumor size in this subgroup. Tests for race-size method of detection interactions were statistically significant for overall survival (p = 0.049), locoregional control (p = 0.036), and distant control (p = 0.032) and borderline significant for disease-free survival (p = 0.067). Conclusion: Despite detection at comparable sizes, the prognostic effect of tumor size in patients with mammographically detected tumors is greater for black than in nonblack patients.

    Purpose To evaluate peri-operative multicatheter interstitial pulsed-dose-rate brachytherapy (PDR-BT) with an intra-operative catheter placement to boost the tumor excision site in breast cancer patients treated conservatively. Material and methods Between May 2002 and October 2008, 96 consecutive T1-3N0-2M0 breast cancer patients underwent breast-conserving therapy (BCT) including peri-operative PDR-BT boost, followed by whole breast external beam radiotherapy (WBRT). The BT dose of 15 Gy (1 Gy/pulse/h) was given on the following day after surgery. Results No increased bleeding or delayed wound healing related to the implants were observed. The only side effects included one case of temporary peri-operative breast infection and 3 cases of fat necrosis, both early and late. In 11 patients (11.4%), subsequent WBRT was omitted owing to the final pathology findings. These included eight patients who underwent mastectomy due to multiple adverse prognostic pathological features, one case of lobular carcinoma in situ, and two cases with no malignant tumor. With a median follow-up of 12 years (range: 7-14 years), among 85 patients who completed BCT, there was one ipsilateral breast tumor and one locoregional nodal recurrence. Six patients developed distant metastases and one was diagnosed with angiosarcoma within irradiated breast. The actuarial 5- and 10-year disease free survival was 90% (95% CI: 84-96%) and 87% (95% CI: 80-94%), respectively, for the patients with invasive breast cancer, and 91% (95% CI: 84-97%) and 89% (95% CI: 82-96%), respectively, for patients who completed BCT. Good cosmetic outcome by self-assessment was achieved in 58 out of 64 (91%) evaluable patients.

    Breast augmentation is the most commonly performed surgical procedure in aesthetic plastic surgery. Accurate pre-operative planning is crucial to obtain the best outcomes. We present our planning method deriving from a more than 30-year experience in aesthetic breast surgery, matching together patients tissues' characteristics and patients' wishes. We schematized our planning method in an easy-to-use flow diagram to help the decisional process in breast augmentation.

    Early onset breast cancer is associated with poor outcomes but variable results have been reported. It is a significant problem in Pakistani women but remains under reported. Breast conservation plays an important role in surgical management of this younger patient group. The objective of this study was to determine the outcome of breast conservative therapy in patients with early onset breast cancer in our population and compare it with their older counterparts. A review of patients with invasive breast cancer who underwent breast conservation surgery at Shaukat Khanum Cancer Hospital from 1997 to 2009 was performed. Patients were divided into two groups i.e. Group I age ≤ 40 and Group II >40 years. A total of 401 patients with breast cancer were identified in Group I and 405 patients in Group II. Demographics, histopathological findings and receptor status of the two groups were compared. The Chi square test was used for categorical variables. Outcome was assessed on basis of 10 year locoregional recurrence free survival (LRRFS), disease free survival (DFS) and overall survival (OS) . For survival analysis Kaplan Meier curves were used and significance was determined using the Log rank test. Cox regression was applied for multivariate analysis. Median follow up was 4.31 (0.1-15.5) years. Median age at presentation was 34.6 years (17-40) and 51.9 years (41-82) for the two groups. Groups were significantly different from each other with respect to grade, receptor status, tumor stage and use of neoadjuvant therapy. No significant difference was present between the two groups for estimated 10 year LRRFS (86% vs 95%) (p=0.1), DFS (70% vs 70%) (p=0.5) and OS (75% vs 63%) (p=0.1). On multivariate analysis, tumor stage was an independent predictor of LRRFS, DFS and OS. Early onset breast cancer is associated with a distinct biology but does not lead to poorer outcomes in our population.

    The prevalence of risk factors contributing to metabolic syndrome (MetS) is increasing, and numerous components of MetS are associated with increased primary breast cancer (BC) risk. However, less is known about the relationship of MetS to BC outcomes. The aim of this study was to evaluate whether MetS, characterized by increased weight, hypertension, low HDL-cholesterol, high triglycerides, and diabetes or impaired glucose tolerance, is associated with risk of second breast cancer events (SBCE) and BC-specific mortality. Retrospective cohort study of women diagnosed with incident early-stage (I-II) BC between 1990 and 2008, enrolled in an integrated health plan. Outcomes of interest were SBCE, defined as recurrence or second primary BC, and BC-specific mortality. We used multivariable Cox proportional hazards models to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for time-varying exposure to MetS components while accounting for potential confounders and competing risks. Among 4,216 women in the cohort, 26% had ≥3 MetS components and 13% developed SBCE during median follow-up of 6.3 years. Compared to women with no MetS components, presence of MetS (≥3 components) was associated with increased risk of SBCE (HR = 1.50, 95% CI 1.08-2.07) and BC-specific mortality (HR = 1.65, 95% CI 1.02-2.69). Of the individual components, only increased weight was associated with increased risk of SBCE (HR = 1.26, 95% CI 1.06-1.49). MetS is associated with modestly increased risk of SBCE and BC-specific mortality. Given the growing population of BC survivors, further research in larger and more diverse populations is warranted.

    The breast surgeries are classically taught as clean surgical procedures. The infection rates following breast surgery ranges from 3 to 15 %, which is much higher than infection rates after clean surgery (ranging from 1.5 to 3 %). This high infection rate following breast surgery can be explained by opening of the ductal system to outside world through nipple similar to the gastrointestinal and genitourinary system. We conducted a systematic review of infection following breast surgeries. We searched various randomized controlled trials, meta-analysis, and Cochrane Reviews over PubMed and Medline via the Internet. These evidences were found to support the thesis, "Breast surgeries need to be reclassified as clean-contaminated". We recommend the use of prophylactic antibiotics in breast surgery.

    The benefits of adjuvant systemic therapy in reducing risk of distant relapse from breast cancer have been recognized for several decades. The intent of adjuvant therapy is to eliminate the occult micrometastatic breast cancer burden before it progresses into clinically apparent disease. Successful delivery of effective adjuvant systemic therapy as a complement to surgical management of breast cancer has contributed to the steady declines in breast cancer mortality observed internationally over the past 2 decades. Ongoing clinical and translational research in breast cancer seeks to improve the efficacy of systemic agents for use in the conventional postoperative (adjuvant) setting.

    Traditional biomedical imaging technology has a difficulty in detecting the boundary of a breast tumor at its early stage since the difference in the sound resistance or density between the early breast tumor and normal tissue is small. In this paper, the boundary of an early breast tumor is detected successfully by using a new method called DSF-DOT (delta sound field diffusion optical tomography), which is based on a sound field and the light diffusion theory. At the same time, the influence of the size of the acting area of the sound field on the reconstruction of the tumor boundary is investigated in details. The work is useful for further research on the diagnosis of early breast cancers.

    Breast cancer is the second leading cause of cancer death among US women, and the chance of a woman developing breast cancer sometime during her lifetime is one in eight. Early detection and diagnosis to allow appropriate locoregional and systemic treatment are key to improve the odds of surviving its diagnosis. Emerging data also suggest that different breast cancer subtypes (phenotypes) may respond differently to available adjuvant therapies. There is a growing understanding that not all patients benefit equally from systemic therapies, and therapeutic approaches are being increasingly personalized based on predictive biomarkers of clinical benefit. Optimal use of established and novel radiological imaging methods, such as magnetic resonance imaging and positron emission tomography, which have different biophysical mechanisms can simultaneously identify key functional parameters. These methods provide unique multiparametric radiological signatures of breast cancer, that will improve the accuracy of early diagnosis, help select appropriate therapies for early stage disease, and allow early assessment of therapeutic benefit.

    Shortly after diagnosis of breast cancer 416 patients were interviewed about their use of screening procedures and the method of tumour detection. Although 72% reported that they performed breast self-examination (BSE), only 12% actually inspected and palpated their breasts monthly. BSE was not significantly associated with tumour size or involvement of the lymph nodes; however, thorough inspection was associated with smaller tumours, and careful palpation with the absence of palpable nodes. Of those who no longer or never had examined their breasts 40% reported having annual breast examinations by their physician and had significantly smaller tumours than did the others. Most of the women (86%) reported having detected their own tumours, and BSE did not significantly increase the likelihood of self-detection. The frequency of use of screening procedures was similar in a sample of women without breast cancer. PMID:6498686

    This review summarizes methods related to the study of human breastmilk in etiologic and biomarkers research. Despite the importance of reproductive factors in breast carcinogenesis, factors that act early in life are difficult to study because young women rarely require breast imaging or biopsy, and analysis of critical circulating factors (e.g. hormones) is often complicated by the requirement to accurately account for menstrual cycle date. Accordingly, novel approaches are needed to understand how events such as pregnancy, breastfeeding, weaning, and post-weaning breast remodeling influence breast cancer risk. Analysis of breastmilk offers opportunities to understand mechanisms related to carcinogenesis in the breast, and to identify risk markers that may inform efforts to identify high-risk women early in the carcinogenic process. In addition, analysis of breastmilk could have value in early detection or diagnosis of breast cancer. In this article we describe the potential for using breastmilk to characterize the microenvironment of the lactating breast with the goal of advancing research on risk assessment, prevention, and detection of breast cancer.

    We treated randomly 75 premenopausal patients with advanced breast cancer with combination chemotherapy (5-fluorouracil, cyclophosphamide and prednisone), either as an early adjunct to oophorectomy or as a delayed treatment upon appearance of progressive metastatic disease after operation. The group receiving early systemic chemotherapy enjoyed an improved response rate, an improved survival rate and, most importantly, an improved progression-free interval (median of 53 versus 17 weeks). With the exclusion of the group with early (within three weeks after oophorectomy) progression, the progression-free intervals had a median duration of 77 weeks in the early-treatment group versus 33 weeks in the control group. The early-progression group did exceedingly poorly, although systemic chemotherapy was employed at that juncture, having a median survival of 22 weeks as compared to 144 weeks in the immediate-treatment group and 105 weeks in the control group.

    Using a new procedure termed fiberoptic ductoscopy, a surgeon can visualize a patient's breast mammary ducts directly with a 0.9-mm scope. Eighty-five percent of breast cancers are thought to originate in the epithelial lining of the mammary ducts. The hope is that this new technique will allow surgeons to detect breast cancer in high-risk patients before a mass is felt or seen via mammography.

    The calpains are a family of intracellular cysteine proteases that function in a variety of important cellular functions, including cell signalling, motility, apoptosis and survival. In early invasive breast cancer expression of calpain-1, calpain-2 and their inhibitor, calpastatin, have been associated with clinical outcome and clinicopathological factors.The expression of calpain-1, calpain-2 and calpastatin was determined using immunohistochemistry on core biopsy samples, in a cohort of large but operable inflammatory and non-inflammatory primary breast cancer patients treated with neoadjuvant chemotherapy. Information on treatment and prognostic variables together with long-term clinical follow-up was available for these patients. Diagnostic pre-chemotherapy core biopsy samples and surgically excised specimens were available for analysis.Expression of calpastatin, calpain-1 or calpain-2 in the core biopsies was not associated with breast cancer specific survival in the total patient cohort; however, in patients with non-inflammatory breast cancer, high calpastatin expression was significantly associated with adverse breast cancer-specific survival (P=0.035), as was low calpain-2 expression (P=0.031). Low calpastatin expression was significantly associated with adverse breast cancer-specific survival of the inflammatory breast cancer patients (P=0.020), as was low calpain-1 expression (P=0.003).In conclusion, high calpain-2 and low calpastatin expression is associated with improved breast cancer-specific survival in non-inflammatory large but operable primary breast cancer treated with neoadjuvant chemotherapy. In inflammatory cases, high calpain-1 and high calpastatin expression is associated with improved breast cancer-specific survival. Determining the expression of these proteins may be of clinical relevance. Further validation, in multi-centre cohorts of breast cancer patients treated with neoadjuvant chemotherapy, is warranted.

    We used a 1D wavelet transform modulus maxima (WTMM) method to analyze the temporal fluctuations of breast skin temperature recorded with an infrared (IR) camera from a panel of patients with breast cancer. This study shows that the multifractal complexity of temperature fluctuations observed in healthy breasts, is lost in the region of the malignant tumor in cancerous breasts. Then, we applied the 2D WTMM method to analyze the spatial fluctuations of breast density in the X-ray mammograms of the same patients. Compared to the correlated roughness fluctuations observed in the healthy areas, some clear loss of correlations is detected in malignant tumor foci. These physiological and architectural changes in the environment of malignant tumors detected in both thermograms and mammograms open new perspectives in computer-aided multifractal methods to assist in early breast cancer diagnosis.

    Early diagnosis is the key for the successful treatment of breast cancer. A serum marker for the early detection of breast cancer could significantly reduce breast cancer morbidity and mortality by bringing the time of diagnosis at an earlier and therefore still curable stage. So far, no biomarker for the early detection is available for the clinical routine. The aim of the present study was to evaluate the use of calponin-h2 as a blood-based biomarker for the early diagnosis of this disease. Using two monoclonal antibodies against calponin-h2, we developed a sandwich ELISA to analyze the serum levels of calponin-h2. In order to evaluate the diagnostic potential of this biomarker, patients with breast cancer (n = 76), benign diseases of the breast (n = 51) and healthy females (n = 24) were analyzed. Serum levels above 10 ng/ml were only observed in patients with breast cancer (n = 8; 10.5%). Further large-scale studies and preanalytic evaluations are necessary to clarify the definite role of calponin-h2 as a biomarker in breast cancer management.

    Considerable literature exists on the benefits of breast feeding on the health and survival of infants and young children, but there is less on the effects on later life outcomes. One such measure of health and well-being that has received attention in the historical literature is terminal adult stature. Information on height is rather widely available; however, it is much more difficult to obtain data on breast feeding. One country that does have such information is Imperial Germany (1871–1919). A number of physicians and local health officials collected information on the incidence and duration of breast feeding early in the 20th century, particularly because of concern about the unusually high infant mortality rates in parts of Germany. Hallie Kintner has surveyed the published results of these studies. The information on the prevalence of breast feeding for the period 1903/10 has been inputed into a database of demographic and economic variables for the counties (Regierungsbezirke) of Germany (1850–1939) There are also published data on heights of military recruits from the Imperial German military forces in 1906. These can be linked to areas in the database and related to breast feeding practices and infant mortality both contemporaneously and approximately 20 years previous to 1906. Results indicate a significant effect of infant feeding practices on later life outcomes operating through infant health conditions, proxied by the infant mortality rate. PMID:18715833

    A recent nation-wide population based retrospective cohort study from Taiwan in 2014 suggested a propensity of developing breast cancer in young females with early-onset cataract. We report here a case of a young non-obese female who presented to us with a large lump in the right breast with skin nodules and bilateral painless progressive diminution of vision. Patient was diagnosed to be suffering from locally advanced carcinoma of right breast with axillary metastasis (Stage III B) and bilateral early-onset nuclear cataract. Patient was started on taxane and anthracycline based neoadjuvant chemotherapy and after three cycles of chemotherapy patient showed partial response (≈50% reduction of tumour mass). Patient underwent small incision cataract surgery in left eye after the first cycle of chemotherapy. However, the patient was lost before any operative intervention could be done as she died in a road traffic accident. Possible mechanism of development of breast cancer in patients with early-onset cataract is discussed. This is the first reported case of a patient of early–onset cataract developing breast cancer as well as the first reported case of concomitant presence of early-onset bilateral cataract with breast cancer.

    Abstract The aim of this study was to evaluate the association between pretreatment molecular and clinical factors and axillary lymph node metastases in early breast cancer. A total of 367 consecutive breast cancer patients with cT1–2NxM0 who underwent breast conserving surgery and axillary lymph node dissection followed by whole breast irradiation were enrolled. We evaluated the pathologic tumor and node status, tumor differentiation, calcification, and lymphovascular invasion, the status of estrogen receptor (ER), progesterone receptor (PR), epidermal growth factor receptor 1 (EGFR1), and human epidermal growth factor receptor 2 (HER2), the expression of E-cadherin, P53, and Ki-67 index. Totally, 108 (29.4%) of the 367 patients had positive axillary lymph nodes. An increased tumor size (P = 0.024), the presence of lymphovascular invasion (P < 0.001), and Ki-67 index of >20% (P = 0.038) were significantly associated with axillary lymph node metastases on the multivariate analysis. In our study, 86.2% of the patients with all the unfavorable factors had an involvement of axillary nodal metastases, and only 12.2% of the patients with all the favorable predictors had positive axillary nodes. The predictive power was significant on the receiver operating curve (P < 0.001). We found that several factors, such as tumor size, lymphovascular invasion, and the Ki-67 index, are independent factors that predict positive ALNM on multivariate analysis for the patients with cT1–2 breast cancer. Clinicians simply could predict the probability of ALNM after verifying the molecular and clinical factors in early breast cancer. PMID:27196477

    The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft, launched in August 2004 under NASA's Discovery Program, was inserted into orbit about the planet Mercury in March 2011. MESSENGER's three flybys of Mercury in 2008-2009 marked the first spacecraft visits to the innermost planet since the Mariner 10 flybys in 1974-1975. The unprecedented orbital operations are yielding new insights into the nature and evolution of Mercury. The scientific questions that frame the MESSENGER mission led to the mission measurement objectives to be achieved by the seven payload instruments and the radio science experiment. Interweaving the full set of required orbital observations in a manner that maximizes the opportunity to satisfy all mission objectives and yet meet stringent spacecraft pointing and thermal constraints was a complex optimization problem that was solved with a software tool that simulates science observations and tracks progress toward meeting each objective. The final orbital observation plan, the outcome of that optimization process, meets all mission objectives. MESSENGER's Mercury Dual Imaging System is acquiring a global monochromatic image mosaic at better than 90% coverage and at least 250 m average resolution, a global color image mosaic at better than 90% coverage and at least 1 km average resolution, and global stereo imaging at better than 80% coverage and at least 250 m average resolution. Higher-resolution images are also being acquired of targeted areas. The elemental remote sensing instruments, including the Gamma-Ray and Neutron Spectrometer and the X-Ray Spectrometer, are being operated nearly continuously and will establish the average surface abundances of most major elements. The Visible and Infrared Spectrograph channel of MESSENGER's Mercury Atmospheric and Surface Composition Spectrometer is acquiring a global map of spectral reflectance from 300 to 1450 nm wavelength at a range of incidence and emission

    Body size in early life is inversely associated with adult breast cancer (BC) risk, but it is unclear whether the associations differ by tumor characteristics. In a pooled analysis of two Swedish population-based studies consisting of 6731 invasive BC cases and 28,705 age-matched cancer-free controls, we examined the associations between body size in early life and BC risk. Self-reported body sizes at ages 7 and 18 years were collected by a validated nine-level pictogram (aggregated into three categories: small, medium and large). Odds ratios (OR) and corresponding 95% confidence intervals (CI) were estimated from multivariable logistic regression models in case-control analyses, adjusting for study, age at diagnosis, age at menarche, number of children, hormone replacement therapy, and family history of BC. Body size change between ages 7 and 18 were also examined in relation to BC risk. Case-only analyses were performed to test whether the associations differed by tumor characteristics. Medium or large body size at age 7 and 18 was associated with a statistically significant decreased BC risk compared to small body size (pooled OR (95% CI): comparing large to small, 0.78 (0.70-0.86), Ptrend <0.001 and 0.72 (0.64-0.80), Ptrend <0.001, respectively). The majority of the women (~85%) did not change body size categories between age 7 and 18 . Women who remained medium or large between ages 7 and 18 had significantly decreased BC risk compared to those who remained small. A reduction in body size between ages 7 and 18 was also found to be inversely associated with BC risk (0.90 (0.81-1.00)). No significant association was found between body size at age 7 and tumor characteristics. Body size at age 18 was found to be inversely associated with tumor size (Ptrend = 0.006), but not estrogen receptor status and lymph node involvement. For all analyses, the overall inferences did not change appreciably after further adjustment for adult body mass index. Our data

    Purpose: To evaluate cosmetic outcome and its association with breast wound seroma after breast-conserving surgery (BCS) with targeted intraoperative radiation therapy (tIORT) boost for early breast cancer. Methods and Materials: An analysis of a single-arm prospective study of 55 patients with early breast cancer treated with BCS and tIORT boost followed by conventional whole breast radiation therapy (WBRT) between August 2003 and January 2006 was performed. A seroma was defined as a fluid collection at the primary tumor resection site identified clinically or radiologically. Cosmetic assessments using the European Organization for Research and Treatment of Cancer rating system were performed at baseline before BCS and 30 months after WBRT was completed. Results: Twenty-eight patients (51%) developed a seroma, with 18 patients (33%) requiring at least 1 aspiration. Tumor location was significantly associated with seroma formation (P=.001). Ten of 11 patients with an upper inner quadrant tumor developed a seroma. Excellent or good overall cosmetic outcome at 30 months was observed in 34 patients (62%, 95% confidence interval 53%-80%). Seroma formation was not associated with the overall cosmetic result (P=.54). Conclusion: BCS with tIORT boost followed by WBRT was associated with an acceptable cosmetic outcome. Seroma formation was not significantly associated with an adverse cosmetic outcome.

    To describe the current role of radiation therapy and specific types of radiation therapy used in the management of early stage, locoregionally advanced, and metastatic breast cancer. The role of radiation therapy in the management of breast cancer has not changed in recent decades, however methods of treatment delivery have advanced considerably. Hypofractionation and accelerated partial breast irradiation, which substantially reduce radiation treatment duration, have emerged as appropriate alternatives to conventional whole breast radiation in select patient subsets, and intensity modulated radiation therapy, breathing-adapted radiation therapy, and prone-positioning technique address challenging anatomic issues and reduce treatment-associated toxicity. Stereotactic radiosurgery and stereotactic body radiation therapy continue to advance the management of distant metastatic disease. Radiation therapy plays a significant role in the management of early stage, locoregionally advanced, and metastatic breast cancer. Technological advances are allowing for greater patient convenience and comfort in locoregional radiation therapy delivery and for expanded radiation therapy indications in the setting of metastatic disease.

    Background Bilateral breast magnetic resonance imaging (MRI) is commonly used in the diagnostic workup of breast cancer (BC) to assess extent of disease and identify occult foci of disease. However, evidence for routine use of pre-operative MRI is lacking. Breast MRI is costly and can lead to unnecessary tests and treatment delays. Clinical care pathways (care paths) are value-based guidelines, which define management recommendations derived by expert consensus and available evidence based data. At Cleveland Clinic, care paths created for newly diagnosed BC patients recommend selective use of pre-operative MRI. We evaluated the number of pre-operative MRIs ordered before and after implementing an institution wide BC care paths in April 2014. Methods A retrospective review was conducted of BC cases during the years 2012, 2014, and part of 2015. Patient, tumor and treatment characteristics were collected. Pre-operative MRI utilization was compared before and after care path implementation. Results We identified 1,515 BC patients during the study period. Patients were more likely to undergo pre-operative MRI in 2012 than 2014 (OR: 2.77; P<0.001; 95% CI: 1.94–3.94) or 2015 (OR: 4.14; P<0.001; 95% CI: 2.51–6.83). There was a significant decrease in pre-operative MRI utilization between 2012 and 2014 (P<0.001) after adjustment for pre-operative MRIs ordered for care path indications. Conclusions Implementation of online BC care paths at our institution was associated with a decreased use of pre-operative MRI overall and in patients without a BC care path indication, driving value based care through the reduction of pre-operative breast MRIs.

    We investigated quantity and quality of dietary carbohydrate as well as insulin load and insulin index during adolescence and also early adulthood in relation to risk of breast cancer in the Nurses' Health Study II. During 20 years of follow-up of 90,534 premenopausal women who completed a diet questionnaire in 1991, 2,833 invasive breast cancer cases were documented. In 1998, 44,263 of these women also completed a questionnaire about their diet during high school; among these women, we documented 1,118 cases of breast cancer. Multivariable-adjusted Cox proportional hazards regression was used to model relative risks (RR) and 95% confidence intervals (95% CI) for breast cancer across categories of dietary carbohydrate, glycemic index (GI), glycemic load (GL), as well as insulin load and insulin index scores. Adolescent or early adult intakes of GI or GL were not associated with risk of breast cancer. Comparing women in the highest versus lowest quintile, the multivariable-adjusted RRs were 1.14 (0.95-1.38) for adolescent GI scores and 1.03 (0.91-1.16) for early adulthood GI scores. We also did not observe associations with insulin index and insulin load scores in adolescence or early adulthood and breast cancer risk. We found that diets high in GI, GL, insulin index, and insulin load during adolescence or early adulthood were not associated with an increased risk of breast cancer in this cohort study. Diets with a high glucose or insulin response in adolescence or early adulthood were not significant predictors of breast cancer incidence. ©2015 American Association for Cancer Research.

    Neoadjuvant chemotherapy (NAC) in breast cancer is currently used not only for locally advanced tumors, but also for large operable tumors when breast preservation is considered. It also provides the opportunity to evaluate chemotherapy tumor response. Our aim was to correlate the relative change in the standardized uptake value (SUV) of (18)F-2-fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET/CT) with pathologic response after NAC. We prospectively evaluated 40 patients with invasive ductal breast carcinomas from February 2010 to December 2011. FDG-PET/CT was performed at baseline and after the second cycle of NAC. All patients underwent surgery after NAC. Pathologic response was evaluated according to Residual Cancer Burden (RCB) index. The mean age was 41.9 years. Median primary tumor size was 6 cm. Pathologic complete response (pCR) was obtained in 12 (30%) patients. The tumor baseline mean maximum SUV (SUV(max)), and after second cycle were: 8.97 (sd.4.3) and 4.07 (sd.3.2), respectively. The relative change (ΔSUV) after the second course of NAC was significantly higher for patients with pCR (-81.58%) when compared to the non-pCR patients (-40.18%) (p = 0.001). The optimal ΔSUV threshold that discriminates between pCR and non-pCR was -71.8% (83.3% sensitivity; 78.5% specificity). Moreover, the optimal ΔSUV threshold to discriminate between NAC responders and non-responders was -59.1% (68% sensitivity; 75.0% specificity). Our data suggest that the FDG-PET/CT ΔSUV after the second course of NAC can predict pathological response in ductal breast carcinomas, and potentially identify a subgroup of non-responding patients for whom ineffective chemotherapy should be avoided. Breast cancer is the most frequently diagnosed cancer in women. The indications for neoadjuvant chemotherapy are increasing. Early information on chemotherapy response is crucial and methods that predict the therapeutic effectiveness might avoid potentially ineffective

    The treatment of primary breast cancer usually consists of surgery often followed by adjuvant therapy (radiotherapy, chemotherapy, hormonal treatment, etc.) to reduce the risk of recurrence. The cancer diagnosis and the treatments may have significant impact on the patients' quality of life. This thesis deals with scientific aspects and clinical results of a study aimed at assessing the impact of breast cancer (and its treatment) on the patients' quality of life. Studies such as this assessing the problems and symptoms experienced by the patients are often referred to as health-related quality of life (HRQL) research. HRQL research deals with subjective experiences and raises challenging, scientific questions. Therefore, much attention was directed towards methodological issues in this clinically motivated project. The study was a prospective, longitudinal, questionnaire-based investigation of women with newly diagnosed breast cancer registered in the Danish Breast Cancer Co-operative Group's DBCG 89 Program. The patients were sub-divided into low-risk and high-risk patients. High-risk patients were offered randomisation in one of three randomised adjuvant therapy trials involving chemotherapy, ovarian ablation, and endocrine therapy. After a literature study and interviews with breast cancer patients, a questionnaire was composed that included two widely used standard questionnaires (EORTC QLQ-C30 and Hospital Anxiety and Depression (HAD) Scale) and a DBCG 89 Questionnaire developed for this study. A total of 1,898 eligible patients were invited by post to participate in the study involving six assessments over a 2-year period, and 1,713 patients (90%) completed the first questionnaire. Furthermore, a questionnaire was sent to 872 women selected at random from the general population; 608 (70%) responded. The multi-item scales of the two standard questionnaires were analysed for so-called differential item functioning (DIF) in order to investigate whether the

    Objective: We review the types, indications, and common regimens of systemic forms of therapy offered in early-stage breast cancer. We further detail the mechanism of action, approved uses, major toxicities, and relevance to breast reconstruction of specific agents. Methods: A review of the literature on PubMed and Cochrane databases was undertaken to define the indications and common regimens of systemic therapy in early-stage breast cancer. In addition, literature describing relevant information regarding specific systemic agents was reviewed. Results: The main objectives of systemic therapy, when provided in the perioperative setting, are to reduce the risk for future recurrence and prolong overall survival. Systemic forms of therapy consist of chemotherapy, hormonal therapy, and targeted therapy and are increasingly being offered to women with early-stage breast cancer. Similarly, as more women are diagnosed with disease that is amenable to surgical extirpation, rates of breast reconstruction are on the rise. Many agents have effects that may impact patient safety with respect to breast reconstruction. Conclusions: Increasingly, women with breast cancer receive 1 or more forms of systemic therapy during the course of their treatment. It is therefore of significant importance that plastic surgeons have a clear understanding of the issues surrounding the use of systemic agents.

    Adjuvant treatment of breast cancer has resulted in significant improvement in breast cancer-related outcomes. In addition to chemotherapy and endocrine therapy, the bone-protective agents known as bisphosphonates have been extensively investigated for their putative antitumor effect. Backed by strong preclinical data from in vitro and in vivo models, several randomized clinical trials have evaluated the role of bisphosphonates in an adjuvant setting. The recent NSABP B-34 (National Surgical Adjuvant Breast and Bowel Project protocol B-34) and AZURE (Adjuvant Zoledronic Acid to Reduce Recurrence) studies found no disease-free survival benefit with clodronate and zoledronate, respectively, whereas the ABCSG-12 (Austrian Breast and Colorectal Cancer Study Group trial 12) study found improvement in disease-free survival with zoledronate. Data from these trials suggested a beneficial effect of bisphosphonates in older, postmenopausal women and in premenopausal women treated with ovarian suppression. Given the acceptable toxicity profile of bisphosphonates, these agents could be a useful adjunct to adjuvant chemotherapy or endocrine treatment for early-stage breast cancer in a carefully selected subset of patients. This review aims to critically synthesize the results of clinical trials of adjuvant bisphosphonates in early-stage breast cancer, and to provide guidelines for the use of these agents in early-stage breast cancer.

    Breast cancer is one of the main causes of women death worldwide. Breast tumor is an early stage of cancer that locates in cells of a human breast. As there is no remedy, early detection is crucial. Towards this, Ultra-Wideband (UWB) is a prominent candidate. It is a wireless communication technology which can achieve high bandwidth with low power utilization. UWB is suitable to be used for short range communication systems including breast cancer detection since it is secure, non-invasive and human health friendly. This paper presents the low-cost and non-invasive early breast cancer detection strategy using UWB sensor (or antenna). Emphasis is given here to detect breast tumor in 2D and 3D environments. The developed system consisted of hardware and software. Hardware included UWB transceiver and a pair of home-made directional sensor/antenna. The software included feed-forward back propagation Neural Network (NN) module to detect the tumor existence, size and location along with soft interface between software and hardware. Forward scattering technique was used by placing two sensors diagonally opposite sides of a breast phantom. UWB pulses were transmitted from one side of phantom and received from other side, controlled by the software interface in PC environment. Collected received signals were then fed into the NN module for training, testing and validation. The system exhibited detection efficiency on tumor existence, location (x, y, z), and size were approximately 100%, (78.17%, 70.66%, 92.46%), 85.86% respectively. The proposed UWB based early breast cancer detection system could be more practical with low-cost, user friendly and non-harmful features. This project may help users to monitor their breast health regularly at their home.

    The present study aimed to investigate risk factors for early onset breast cancer that are related to lifestyle and psychological stress. A comparative case-control study was performed among patients from the Department of Breast Surgery in Shanghai Cancer Center of Fudan University. The information regarding risk factors associated with the development of early onset breast cancer was collected using a questionnaire in a face-to-face interview. The distribution of the risk factors associated with the development of early onset breast cancer between the patient group and the control group was analyzed with logistic regression. A total of 582 cases of young patients (≤40 years old) with breast cancer and 540 controls of young patients (≤40 years old) with benign breast disease were included in this study. The risk factors for breast cancer in young women include age at first birth (odds ratio [OR] = 0.93, 95% confidence interval [CI]: 0.88-0.98), history of breast cancer in an immediate family member (OR = 2.36, 95% CI: 1.14-4.89), history of genital surgery (OR = 2.11, 95% CI: 1.16-3.82), active and passive smoking in daily life or the environment (OR = 1.64, 95% CI: 1.19-2.25), weekly intake of soy products (OR = 1.24, 95% CI: 1.02-1.49), use of household cooking oil (OR = 2.04, 95% CI: 1.04-4.00), disharmonious marital status (OR = 1.16, 95% CI: 1.06-1.26), frequent depression (OR = 1.32, 95% CI: 1.00-1.75), and negative emotional experiences (OR = 1.15, 95% CI: 1.03-1.29). Our study could provide the basis for risk assessment and preventive interventions for early onset breast cancer.

    Nodal staging in breast cancer is a key predictor of prognosis. This paper presents the results of potential clinicopathological predictors of axillary lymph node involvement and develops an efficient prediction model to assist in predicting axillary lymph node metastases. Seventy patients with primary early breast cancer who underwent axillary dissection were evaluated. Univariate and multivariate logistic regression were performed to evaluate the association between clinicopathological factors and lymph node metastatic status. A logistic regression predictive model was built from 50 randomly selected patients; the model was also applied to the remaining 20 patients to assess its validity. Univariate analysis showed a significant relationship between lymph node involvement and absence of nm-23 (p = 0.010) and Kiss-1 (p = 0.001) expression. Absence of Kiss-1 remained significantly associated with positive axillary node status in the multivariate analysis (p = 0.018). Seven clinicopathological factors were involved in the multivariate logistic regression model: menopausal status, tumor size, ER, PR, HER2, nm-23 and Kiss-1. The model was accurate and discriminating, with an area under the receiver operating characteristic curve of 0.702 when applied to the validation group. Moreover, there is a need discover more specific candidate proteins and molecular biology tools to select more variables which should improve predictive accuracy.

    The early growth of micrometastatic breast cancer in the brain often occurs through vessel co-option and is independent of angiogenesis. Remodeling of the existing vasculature is an important step in the evolution of co-opting micrometastases into angiogenesis-dependent solid tumor masses. The purpose of this study was to determine if phase contrast MRI, an intrinsic source of contrast exquisitely sensitive to the magnetic susceptibility properties of deoxygenated hemoglobin, could detect vascular changes occurring independent of angiogenesis in a rat model of breast cancer metastases to the brain. Twelve nude rats were administered with 106 MDA-MB-231BRL “brain seeking” breast cancer cells through intracardiac injection. Serial, multiparametric MRI of the brain was performed weekly until metastatic disease was detected. The results demonstrate that images of the signal phase were more sensitive to metastatic brain lesions (area under receiver operating characteristic curve, AUC = 0.97) compared to T2* gradient echo magnitude images, (AUC = 0.73). The difference between the two techniques was likely the result of the confounding effects of edema on the magnitude signal. A region of interest analysis revealed that vascular abnormalities detected with phase contrast MRI preceded tumor permeability as measured with contrast-enhanced MRI by 1 to 2 weeks. Tumor size was correlated with permeability (R2 = 0.23, p < 0.01), but phase contrast was independent of tumor size (R2 = 0.03). Histopathological analysis demonstrated that capillary endothelial cells coopted by tumor cells were significantly enlarged, but less dense, compared to the normal brain vasculature. Whereas co-opted vessels were VEGF-negative, vessels within larger tumor masses were VEGF-positive. In conclusion, phase contrast MRI is believed to be sensitive to vascular remodeling in co-opting brain tumor metastases independent of sprouting angiogenesis and may therefore aid in pre-clinical studies of

    Pertuzumab increases the rate of pathological complete response in the preoperative context and increases overall survival among patients with metastatic disease when it is added to trastuzumab and chemotherapy for the treatment of human epidermal growth factor receptor 2 (HER2)-positive breast cancer. In this trial, we investigated whether pertuzumab, when added to adjuvant trastuzumab and chemotherapy, improves outcomes among patients with HER2-positive early breast cancer. We randomly assigned patients with node-positive or high-risk node-negative HER2-positive, operable breast cancer to receive either pertuzumab or placebo added to standard adjuvant chemotherapy plus 1 year of treatment with trastuzumab. We assumed a 3-year invasive-disease-free survival rate of 91.8% with pertuzumab and 89.2% with placebo. In the trial population, 63% of the patients who were randomly assigned to receive pertuzumab (2400 patients) or placebo (2405 patients) had node-positive disease and 36% had hormone-receptor-negative disease. Disease recurrence occurred in 171 patients (7.1%) in the pertuzumab group and 210 patients (8.7%) in the placebo group (hazard ratio, 0.81; 95% confidence interval [CI], 0.66 to 1.00; P=0.045). The estimates of the 3-year rates of invasive-disease-free survival were 94.1% in the pertuzumab group and 93.2% in the placebo group. In the cohort of patients with node-positive disease, the 3-year rate of invasive-disease-free survival was 92.0% in the pertuzumab group, as compared with 90.2% in the placebo group (hazard ratio for an invasive-disease event, 0.77; 95% CI, 0.62 to 0.96; P=0.02). In the cohort of patients with node-negative disease, the 3-year rate of invasive-disease-free survival was 97.5% in the pertuzumab group and 98.4% in the placebo group (hazard ratio for an invasive-disease event, 1.13; 95% CI, 0.68 to 1.86; P=0.64).

    The clinical features of the early stages of bisphosphonate-related osteonecrosis of the jaw (BRONJ) in patients with breast cancer remain unclear. A retrospective cohort study was conducted of patients with breast cancer who received intravenous bisphosphonate (BP) treatment in a single center in order to clarify the status of the early stages of BRONJ. A BRONJ oral monitoring program was established in 247 breast cancer patients given intravenous BP treatment at the institution. The differences in age, BP treatment period, number of remaining teeth, oral hygiene status, presence of regular oral monitoring and the existence of suspected BRONJ (stage 0) among eight BRONJ and 36 non-BRONJ subjects who completed oral examinations were then compared. BRONJ was observed in 0.4% of subjects on the first visit to the oral surgery clinic and in 3.2% of subjects during the follow-up period. Logistic regression analysis revealed that the odds ratio for identifying patients with BRONJ during follow-up by the presence of stage 0 at first visit was 24.0 (95% confidence interval [CI] = 3.6-161.7). The area under the receiver operating characteristic curve for identifying subjects with BRONJ by the presence of stage 0 was 0.82 (95% CI = 0.63-1.00). The results suggest that patients with stage 0 BRONJ on the first visit may progress to advanced BRONJ during the follow-up period. The oral monitoring program may contribute to the early detection of BRONJ.

    Purpose To provide current recommendations on the use of sentinel node biopsy (SNB) for patients with early-stage breast cancer. Methods PubMed and the Cochrane Library were searched for randomized controlled trials, systematic reviews, meta-analyses, and clinical practice guidelines from 2012 through July 2016. An Update Panel reviewed the identified abstracts. Results Of the eight publications identified and reviewed, none prompted a change in the 2014 recommendations, which are reaffirmed by the updated literature review. Conclusion Women without sentinel lymph node (SLN) metastases should not receive axillary lymph node dissection (ALND). Women with one to two metastatic SLNs who are planning to undergo breast-conserving surgery with whole-breast radiotherapy should not undergo ALND (in most cases). Women with SLN metastases who will undergo mastectomy should be offered ALND. These three recommendations are based on randomized controlled trials. Women with operable breast cancer and multicentric tumors, with ductal carcinoma in situ, who will undergo mastectomy, who previously underwent breast and/or axillary surgery, or who received preoperative/neoadjuvant systemic therapy may be offered SNB. Women who have large or locally advanced invasive breast cancer (tumor size T3/T4), inflammatory breast cancer, or ductal carcinoma in situ (when breast-conserving surgery is planned) or are pregnant should not undergo SNB.

    Documentary research carried out in 2009 aims to document the regulatory framework and existing programs for the early detection of breast cancer in Latin America and the Caribbean in order to establish the most important challenges for the containment of the epidemic in the region. The governments of the region have developed diverse efforts and initiatives to confront the rise in mortality due to said cause, including early detection, treatment and research strategies. Despite advances in the early detection of breast cancer, the challenge remains to link efforts to ensure continuity of care (diagnostic confirmation, treatment and monitoring) in order to achieve higher efficiency, effectiveness and benefits for women with this disease.

    Background Protein losing enteropathy (PLE) is a challenging complication after Fontan operation. Subclinical enteric protein loss may precede development of overt PLE. We evaluated the acute effects of Fontan circulation on enteric protein loss and mesenteric vascular resistance. Methods A prospective cohort study was performed evaluating enteric protein loss in children undergoing Fontan operation. Stool alpha-1-antitrypsin (A1AT) concentration was measured in the pre-operative, early post-operative, and intermediate post-operative (3–9 months) periods. The intestinal circulation was characterized by Doppler-derived resistance indices of the superior mesenteric artery, and serum albumin and protein levels were obtained. Results We enrolled 33 subjects at a median age at operation of 3.0 (2.5–3.3) years. No clinical PLE was observed. Six of the 93 stool A1AT samples obtained were elevated (>54 mg/dl), with two abnormal samples at each of the three time points. Two of the five subjects with elevated stool A1AT values had significant hemodynamic disturbances requiring intervention (junctional bradycardia or tricuspid stenosis). There was no difference in superior mesenteric artery resistance in the pre-operative versus early post-operative period (p=0.9). Serum albumin levels were lower in the early post-operative period compared to the pre-operative period (3.2 mg/dl [IQR 2.9–3.5] vs. 4.1 mg/dl [IQR 3.4–4.5], p=0.01) but did not correlate with abnormal stool A1AT concentration or superior mesenteric artery resistance indices. Conclusions The Fontan operation does not commonly result in acute development of increased enteric protein loss. However, increased enteric protein loss may occur in children before or after Fontan operation, particularly when hemodynamic disturbances are present. PMID:26652137

  19. Prospective validation of a blood-based 9-miRNA profile for early detection of breast cancer in a cohort of women examined by clinical mammography.

    Mammography is the predominant screening method for early detection of breast cancer, but has limitations and could be rendered more accurate by combination with a blood-based biomarker profile. Circulating microRNAs (miRNAs) are increasingly recognized as strong biomarkers, and we previously developed a 9-miRNA profile using serum and LNA-based qPCR that effectively stratified patients with early stage breast cancer vs. healthy women. To further develop the test into routine clinical practice, we collected serum of women examined by clinical mammography (N = 197) according to standard operational procedures (SOPs) of the Danish Cancer Biobank. The performance of the circulating 9-miRNA profile was analyzed in 116 of these women, including 36 with breast cancer (aged 50-74), following a standardized protocol that mimicked a routine clinical set-up. We confirmed that the profile is significantly different between women with breast cancer and controls (p-value <0.0001), with an AUC of 0.61. Significantly, one woman whose 9-miRNA profile predicted a 73% probability of having breast cancer indeed developed the disease within one year despite being categorized as clinically healthy at the time of blood sample collection and mammography. We propose that this miRNA profile combined with mammography will increase the overall accuracy of early detection of breast cancer. Copyright © 2016 Federation of European Biochemical Societies.

    Most women with breast cancer who undergo breast-conserving surgery receive whole-breast irradiation. We examined whether the addition of regional nodal irradiation to whole-breast irradiation improved outcomes. We randomly assigned women with node-positive or high-risk node-negative breast cancer who were treated with breast-conserving surgery and adjuvant systemic therapy to undergo either whole-breast irradiation plus regional nodal irradiation (including internal mammary, supraclavicular, and axillary lymph nodes) (nodal-irradiation group) or whole-breast irradiation alone (control group). The primary outcome was overall survival. Secondary outcomes were disease-free survival, isolated locoregional disease-free survival, and distant disease-free survival. Between March 2000 and February 2007, a total of 1832 women were assigned to the nodal-irradiation group or the control group (916 women in each group). The median follow-up was 9.5 years. At the 10-year follow-up, there was no significant between-group difference in survival, with a rate of 82.8% in the nodal-irradiation group and 81.8% in the control group (hazard ratio, 0.91; 95% confidence interval [CI], 0.72 to 1.13; P=0.38). The rates of disease-free survival were 82.0% in the nodal-irradiation group and 77.0% in the control group (hazard ratio, 0.76; 95% CI, 0.61 to 0.94; P=0.01). Patients in the nodal-irradiation group had higher rates of grade 2 or greater acute pneumonitis (1.2% vs. 0.2%, P=0.01) and lymphedema (8.4% vs. 4.5%, P=0.001). Among women with node-positive or high-risk node-negative breast cancer, the addition of regional nodal irradiation to whole-breast irradiation did not improve overall survival but reduced the rate of breast-cancer recurrence.

    Early breast cancer affects one in every nine women along with their families. Advances in screening and biomedical interventions have changed the face of breast cancer from a terminal condition to a chronic disease with biopsychosocial features. The present review surveyed the nature and extent of psychological morbidity experienced by the breast cancer survivor and her spouse during the post-treatment phase, with particular focus on the impact of disease on the marital relationship. Interpersonal processes shown to unfold in couples facing breast cancer, as well as risk factors associated with greater psychological morbidity, were reviewed. Moreover, interpersonal processes central to coping with chronic illness and adjustment were reconceptualized from the point of view of attachment theory. Attachment theory was also used as the grounding framework for an empirically supported couples-based intervention, Emotionally Focused Therapy, which is advanced as a potentially useful treatment option for couples experiencing unremitting psychological and relational distress following diagnosis and treatment for breast cancer.

    Breast self-examination (BSE) is of great potential value for the early detection of breast cancer, especially in areas where mammography and regular examinations by physicians are not practicable. However, BSE cannot be recommended for routine public health practice until there is good evidence that it is effective in reducing mortality from breast cancer. Prospective controlled trials of BSE were therefore initiated in 1985 in Leningrad and Moscow, under the auspices of WHO, in order to establish the value of this potentially cost-effective technique. More than 62 000 women aged 40-64 years have been enrolled in the BSE and control groups in Leningrad and another 88 000 will be added in the next three years. This paper presents the results of the study in Leningrad after the first 15 months. PMID:3311442

    Objective: To identify factors that influence Saskatchewan women’s choice between breast conserving therapy (BCT) and mastectomy in early-stage breast cancer (ESBC) and to compare and contrast underlying reasons behind choice of BCT versus mastectomy. Methods: Interpretive description methods guided this practice-based qualitative study. Data were analyzed using thematic analysis and presented in thematic maps. Results: Women who chose mastectomy described 1 of the 3 main themes: worry about cancer recurrence, perceived consequences of BCT treatment, or breast-tumor size perception. In contrast, women chose BCT because of 3 different themes: mastectomy being too radical, surgeon influence, and feminine identity. Conclusions: Although individual reasons for choosing mastectomy versus BCT have been discussed in the literature before, different rationale underlying each choice has not been previously described. These results are novel in identifying interdependent subthemes and secondary reasons for each choice. This is important for increased understanding of factors influencing a complicated decision-making process. PMID:28469511

    Anthracyclines are frequently used in the adjuvant treatment of early-stage breast cancer. However, with the increasing use of other active drugs--mainly taxanes and trastuzumab in HER2-positive disease--coupled with concerns about anthracycline-associated toxic effects, there is debate about whether anthracyclines are still needed. Three major factors should be taken into consideration with the investigation of the role of anthracyclines in management of early breast cancer; specifically, the proven efficacy of anthracyclines in breast cancer, the absence of superiority of non-anthracycline-based chemotherapy over anthracycline-taxane regimens, and the low risk of toxic effects associated with the cumulative doses of anthracyclines used in contemporary regimens. The risks remain substantially outweighed by the benefits of treatment with anthracyclines, and thus, they maintain an important role in adjuvant treatment of breast cancer, particularly in women with high-risk disease.

  7. Effectiveness of early detection on breast cancer mortality reduction in Catalonia (Spain)

    2009-01-01

    Background At present, it is complicated to use screening trials to determine the optimal age intervals and periodicities of breast cancer early detection. Mathematical models are an alternative that has been widely used. The aim of this study was to estimate the effect of different breast cancer early detection strategies in Catalonia (Spain), in terms of breast cancer mortality reduction (MR) and years of life gained (YLG), using the stochastic models developed by Lee and Zelen (LZ). Methods We used the LZ model to estimate the cumulative probability of death for a cohort exposed to different screening strategies after T years of follow-up. We also obtained the cumulative probability of death for a cohort with no screening. These probabilities were used to estimate the possible breast cancer MR and YLG by age, period and cohort of birth. The inputs of the model were: incidence of, mortality from and survival after breast cancer, mortality from other causes, distribution of breast cancer stages at diagnosis and sensitivity of mammography. The outputs were relative breast cancer MR and YLG. Results Relative breast cancer MR varied from 20% for biennial exams in the 50 to 69 age interval to 30% for annual exams in the 40 to 74 age interval. When strategies differ in periodicity but not in the age interval of exams, biennial screening achieved almost 80% of the annual screening MR. In contrast to MR, the effect on YLG of extending screening from 69 to 74 years of age was smaller than the effect of extending the screening from 50 to 45 or 40 years. Conclusion In this study we have obtained a measure of the effect of breast cancer screening in terms of mortality and years of life gained. The Lee and Zelen mathematical models have been very useful for assessing the impact of different modalities of early detection on MR and YLG in Catalonia (Spain). PMID:19754959

    The objective of this study was to determine the changes in peripheral blood circulating tumor cells in HER2-positive early breast cancer before and after Herceptin therapy, and to explore the effects of the HER2 gene and Herceptin on circulating tumor cells. CK19 mRNA expression in peripheral blood was evaluated by qRT-PCR as an index of circulating tumor cells in 15 cases of HER-2-positive breast cancer and 18 cases of HER2-negative breast cancer before, and after chemotherapy as well. Ten cases of HER2-positive breast cancer continued on Herceptin therapy for 3 months after chemotherapy, and their peripheral blood was again drawn and assayed for CK-19 mRNA expression. Preoperatively, all cases of HER2-positive cancer were positive for CK19 mRNA in peripheral blood, but 6 cases of HER2-negative breast cancer were positive (33.3%), where there was a substantial difference between the two groups. After 6 cycles of adjuvant chemotherapy, CK19 positive rates in cases of HER2-positive and -negative breast cancer reduced by 93.3 and 11.1%, respectively, with a significant difference still existing. After 3 months of Herceptin therapy, expression of CK19 mRNA declined considerably in 10 cases of HER2 positive breast cancer (113.66 ± 88.65 vs 63.35 ± 49.27, P = 0.025). HER-2 gene expression closely correlated with circulating tumor cells in peripheral blood of early breast cancer patients. Moreover, Herceptin, a monoclonal antibody for HER2, can reduce the number of circulating tumor cells, which can be an early predictive factor for Herceptin therapy effectiveness against breast cancer.

    The Aim of this level 3 good clinical practice guideline is to help physicians, women and patients in decision making about the appropriate health care for early detection of breast cancer. The principle of early detection of breast cancer comprise the detection and diagnosis of premalignant breast tumors (stage 0, Carcinoma in situ), risk reduction of cancer development as well as the detection and diagnosis of breast cancer at an early stage (stage I), with a 90% chance of cure as shown by a large number of clinical trials. To establish a nation wide, comprehensive quality assuring program for the early detection of breast cancer the guideline summarized in the following paper offers the basis for a timely mortality reduction of breast cancer. The cure of early stage disease will be additionally possible by less invasive treatment allowing patients to maintain quality of life. The guideline leads to a major improvement of women's health care.

    Purpose: Arm lymphedema is a potential consequence of the treatment for breast carcinoma. The objective of this retrospective study was to characterize the progression of mild arm lymphedema after breast conservation treatment for breast cancer. Methods and Materials: The study cohort was drawn from 1,713 consecutive Stage I or II breast cancer patients who underwent breast conservation therapy, including axillary staging followed by radiation. Arm lymphedema was documented in 266 (16%) of 1,713 patients. One hundred nine patients, 6% of the overall group and 40% of the patients with arm lymphedema, presented with mild arm lymphedema, defined as a difference of 2 cm or less between the measured circumferences of the affected and unaffected arms. Results: Among the 109 patients with mild arm lymphedema at the time of arm lymphedema diagnosis, the rate of freedom from progression to more severe lymphedema was 79% at 1 year, 66% at 3 years, and 52% at 5 years. The patients who were morbidly obese, had positive axillary lymph nodes, or received supraclavicular irradiation at the time of breast cancer treatment were at higher risk of progression from mild arm lymphedema to more severe edema. Conclusions: Mild arm lymphedema, generally considered to be a minor complication after breast conservation treatment for breast cancer, was associated with a risk of progression to a more severe grade of arm lymphedema in a substantial fraction of patients.

    Over 40% of breast cancer patients are diagnosed above the age of 65. Treatment of these elderly patients will probably vary over countries. The aim of this study was to make an international comparison (several European countries and the US) of surgical and radiation treatment for elderly women with early stage breast cancer. Survival comparisons were also made. Data were obtained from national or regional population-based registries in the Netherlands, Switzerland, Ireland, Belgium, Germany, and Portugal. For the US patients were selected from the Surveillance, Epidemiology, and End Results (SEER) database. Early stage breast cancer patients aged ≥ 65 diagnosed between 1995 and 2005 were included. An international comparison was made for breast and axillary surgery, radiotherapy after breast conserving surgery (BCS), and relative or cause-specific survival. Overall, 204.885 patients were included. The proportion of patients not receiving any surgery increased with age in many countries; however, differences between countries were large. In most countries more than half of all elderly patients received breast conserving surgery (BCS), with the highest percentage in Switzerland. The proportion of elderly patients that received radiotherapy after BCS decreased with age in all countries. Moreover, in all countries the proportion of patients who do not receive axillary surgery increased with age. No large differences in survival between countries were recorded. International comparisons of surgical treatment for elderly women with early stage breast cancer are scarce. This study showed large international differences in treatment of elderly early stage breast cancer patients, with the most striking result the large proportion of elderly who did not undergo surgery at all. Despite large treatment differences, survival does not seem to be affected in a major way.

    The study was performed in order to determine the behavior of college students studying in health related departments for the early diagnosis of breast cancer. This study is a cross sectional study. 336 female students studying in School of Nursing and School of Health Sciences at a foundation university in Istanbul were included. A questionnaire directed to collect data regarding the participants' socio-demographic characteristics and their behavior on the early diagnosis of breast cancer was used. Data were evaluated by descriptive statistics and chi-square test. The mean age of students was 21.26±1.94, and 30.7% of the participants majored in nutrition, 29.2% in nursing, 22.9% in midwifery, 17.3% in physical therapy and rehabilitation departments. It was determined that 53.3% of the students made regular breast self-examination (BSE), and 88.1% did not get a clinical breast examination (CBE) within the last year. It was noticed that students who had BSE training, made more BSE and CBE as compared to those who did not get any education. Students with family history of breast cancer was performing more BSE that those without a family history. It was identified that students with BSE training and family history of breast cancer used BSE at a higher rate. It was identified that students with BSE training and family history of breast cancer usage of techniques to perform a BSE at a higher rate.

    Breast-feeding is the recommended form of nutrition for the first 6 months. This target is unmet, however, in most industrialized regions. We evaluated aspects of breast-feeding in a cohort of mother-baby dyads. Breast-feeding practices in 555 mother-baby dyads were prospectively studied for 24 months (personal interview at birth and 7 structured telephone interviews). Of the babies, 71.3% were fully breast-fed on discharge from maternity hospitals and 11.9% were partially breast-feed. Median breast-feeding duration was 6.93 (interquartile range 2.57-11.00) months; for full (exclusive) breast-feeding 5.62 (interquartile range 3.12-7.77) months; 61.7% received supplemental feedings during the first days of life. Breast-feeding duration in babies receiving supplemental feedings was significantly shorter (median 5.06 months versus 8.21 months, P < 0.001). At 6 months, 9.4% of the mothers were exclusively and 39.5% partially breast-feeding. Risk factors for early weaning were early supplemental feedings (odds ratio [OR] 2.87, 95% CI 1.65-4.98), perceived milk insufficiency (OR 7.35, 95% CI 3.59-15.07), low breast-feeding self-efficacy (a mother's self-confidence in her ability to adequately feed her baby) (OR 3.42, 95% CI 1.48-7.94), lower maternal age (OR 3.89, 95% CI 1.45-10.46), and lower education level of the mother (OR 7.30, 95% CI 2.93-18.20). The recommended full breast-feeding duration of the first 6 months of life was not reached. Sociodemographic variables and factors directly related to breast-feeding practices play an important role on breast-feeding duration/weaning in our region. Understanding risk factors will provide insights to give better support to mothers and prevent short- and long-term morbidity following early weaning.

    To meaningfully participate in the decision-making regarding a newly diagnosed breast cancer, a patient must acquire new knowledge. We describe a model of knowledge acquisition that can provide a framework for exploring the process and types of knowledge that breast cancer patients gain following their diagnosis. The four types of knowledge presented in this model-authoritative, technical, embodied, and traditional-are described and potential sources discussed. An understanding of knowledge acquisition in early stage breast cancer patients can provide healthcare practitioners with an important framework for optimizing decision-making in this population. © 2012 Wiley Periodicals, Inc.

CD16(+) monocytes are expanded in various inflammatory conditions. However, little is known about the CD14(+) CD16(+) monocytes in patients with breast cancer. We detected CD14(+) CD16(+) monocytes in 96 patients with breast cancer and 54 control subjects using flow cytometry. Receiver-operating characteristic (ROC) curve analysis was used to determine the feasibility of CD14(+) CD16(+) monocytes as an indicator for diagnosis of breast cancer. We found that the frequency of CD14(+) CD16(+) monocytes showed a significantly greater increase in breast cancer patients than in controls (16·96% versus 10·84%, P < 0·0001). The area under the ROC curve for CD14(+) CD16(+) monocytes was 0·805 [95% confidence interval (95% CI): 0·714-0·877, P = 0·0001]. Furthermore, the levels of CD16(+) monocytes were significantly negatively associated with the tumour size and pathological staging. In vitro, we showed that CD14(+) CD16(+) monocytes were expanded significantly when the purified CD14(+) monocytes were exposed to Michigan Cancer Foundation (MCF)-7 cells-conditioned medium (MCF-CM) or, separately, to monocyte chemotactic protein 1 (MCP-1). Neutralizing antibodies against MCP-1 inhibited the expansion of CD14(+) CD16(+) monocytes by MCF-CM. Collectively, our findings indicated that MCP-1 can expand CD14(+) CD16(+) monocytes in patients with breast cancer. Furthermore, the CD14(+) CD16(+) monocyte may be a useful indicator in early diagnosis of breast cancer.

  18. Self-examination in the early detection of breast cancer: Memorandum from a WHO Meeting*

    PubMed Central

    1984-01-01

    Breast self-examination is of interest for the early detection of breast cancer, especially in areas where mammography and regular physical examination of the breasts are not practicable as public health policies. At present, there is insufficient evidence that breast self-examination is effective in reducing mortality from breast cancer. To determine its effectiveness, this method should be applied in a comprehensive programme that provides teaching and guidance on practice of the technique, and facilities for self-referral and diagnosis (when any abnormality is detected) as well as treatment, taking into account the background (economic, social, and cultural) of the country or area concerned. Once the programme has been developed, its effectiveness in reducing breast cancer mortality will have to be assessed in carefully designed research studies. The favoured design for assessment is a randomized controlled trial. Other types of studies, such as quasi-experimental comparisons or a case-control study, are less satisfactory, but may be conducted under strictly specified conditions. Until the effectiveness of breast self-examination has been established, it cannot be recommended as a public health measure for control of breast cancer. PMID:6335844

    This analysis was conducted to determine whether comorbid medical conditions predict additional breast cancer events and all-cause mortality in women with a history of early stage breast cancer. Women (n = 2,542) participating in a randomized diet trial completed a self-administered questionnaire regarding whether they were currently being treated for a wide variety of diseases (cardiovascular, diabetes, gallbladder, gastrointestinal, arthritis, and osteoporosis) and conditions (high blood pressure, elevated cholesterol level). Height and weight were measured at baseline. Participants were followed for a median of 7.3 years (range 0.8-15.0). Cox regression analysis was performed to assess whether comorbidities predicted disease-free and overall survival; hazard ratio (HR) was the measure of association. Overall, there were 406 additional breast cancer events and 242 deaths. Participants with diabetes had over twofold the risk of additional breast cancer events (HR 2.1, 95% CI: 1.3, 3.4) and mortality (HR 2.5, 95% CI: 1.4, 4.4). The presence of multiple comorbidities did not statistically significantly predict additional breast cancer events. However, compared to no comorbidities, participants with 3 or more comorbidities had a HR of 2.1, 95% CI: 1.3, 3.3 for mortality. In conclusion, type 2 diabetes is associated with poor breast cancer prognosis. Given that 85% of deaths were caused by breast cancer, these findings suggest that multiple comorbidities may reduce the likelihood of surviving additional breast cancer events.

    Evidence-based guidelines for long-term follow-up of early-stage breast cancer patients developed by oncology societies in the United States and Europe recommend that breast cancer survivors undergo regular evaluation with history and physical examination, as well as annual mammography. Routine blood tests, circulating tumor markers, and/or surveillance imaging studies beyond mammography are not recommended in the absence of concerning symptoms or physical examination findings because of lack of supportive clinical evidence. Despite these guidelines, studies have shown that 20% to 40% of oncologists assess serum tumor markers as part of routine monitoring of early-stage breast cancer patients. As part of efforts to both address the financial challenges confronting the health-care system and optimize patient outcomes, the American Society of Clinical Oncology’s Cost of Care Task Force identified adherence to breast cancer surveillance guidelines as an opportunity to improve care and reduce cost. However, these recommendations are based on trials done in an era of outdated technology and limited therapeutic options. It is possible that recent improvements in diagnostics and treatments could make earlier detection of recurrent disease important for improving both survival and quality of life outcomes. Research is necessary to further inform optimal breast cancer follow-up strategies, which could impact these recommendations. At this time, outside of well-conducted clinical trials, there is no role for ordering routine serial blood or imaging tests in monitoring for recurrence in early-stage breast cancer patients.

    Objective: To evaluate the safety, cosmesis, and clinical outcome of intraoperative electron radiation therapy (IOERT) delivered prior to lumpectomy for early-stage breast cancer. Methods: From December 2008 to March 2012, 75 breast cancer patients (ages 34-66 years) were treated with IOERT during breast conservative surgery. IOERT was delivered using a mobile linear accelerator. Suitable energy and applicator size were chosen to ensure coverage of the tumor with anterior and posterior margins of 1 cm and lateral margins of 2 cm. Patients with sentinel node metastases or younger than 40 years received 8 Gy as boost followed by post-operative external beam radiation therapy of 50 Gy/25F; the others had 15 Gy, prescribed to the 90% isodose depth. Adjuvant treatment consisted of chemotherapy (55 patients), hormonal therapy (59 patients), or combined chemotherapy and hormonal therapy (41 patients). The safety, cosmesis, and short-term outcome were evaluated. Results: Median follow-up was 54 months (range: 30-66 months). Two (2.7%) patients developed post-surgical hematoma. Six (8.0%) patients developed mild breast fibrosis. Eight (10.7%) patients suffered from local pain. One (1.2%) patient experienced a post-operative infection. Sixteen (21.3%) patients developed Grade 1 pulmonary fibrosis. Forty-three (57.3%) patients had an excellent cosmetic result and 23 (30.7%) had a good cosmetic result. Three patients had an ipsilateral breast recurrence, with an actual 3-year local recurrence rate of 4.0%. One patient had an ipsilateral axillary recurrence, resulting in a 3-year regional recurrence rate of 1.3%. No distant metastases or deaths were observed. The 3-year disease free survival was 94.6%. Conclusions: Intraoperative electron radiation therapy delivered prior to lumpectomy is safe and feasible for selected patients with early-stage breast cancer. Early side effects, cosmesis and short-term efficacy are acceptable, but a longer follow-up is needed for evaluation of

    Purpose: The standard radiotherapy (RT) of breast cancer consists of 50 Gy external beam RT (EBRT) to the whole breast followed by an electron boost of 10-16 Gy to the tumor bed, but this has several cosmetic disadvantages. Intraoperative radiotherapy (IORT) could be an alternative to overcome these. Methods and Materials: We evaluated 50 women with early breast cancer operated on in a dedicated IORT facility. Median dose of 10 Gy was delivered using 9-MeV electron beams. All patients received postoperative EBRT (50 Gy in 2 Gy fractions). Late toxicity and cosmetic results were assessed independently by two physicians according to the Common Terminology Criteria for Adverse Event v3.0 grading system and the European Organization for Research and Treatment of Cancer questionnaires. Results: After a median follow-up of 9.1 years (range, 5-15 years), two local recurrences were observed within the primary tumor bed. At the time of analysis, 45 patients are alive with (n = 1) or without disease. Among the 42 disease-free remaining patients, 6 experienced Grade 2 late subcutaneous fibrosis within the boost area. Overall, the scores indicated a very good quality of life and cosmesis was good to excellent in the evaluated patients. Conclusion: Our results confirm that IORT given as a boost after breast-conserving surgery is a reliable alternative to conventional postoperative fractionated boost radiation.

  4. Early diagnosis of breast cancer: the breast self-examination problem.

    Only ten percent of 1000 consecutive patients attending the St. Michael's Hospital Breast Clinic were practicing breast self-examination regularly. Seventy percent had tried and quit because of confusion, frustration and terror over what they had felt in their breasts. They were encouraged to start again and learn what 'normal' felt like on the night of the clinical examination, after each woman had been reassured that her breasts were 'normal for her'.Of 533 women who have attended subsequently for annual re-examination, 75 percent are practicing breast self-examination regularly, confident that they know what 'normal' feels like and reasonably confident that they can detect any change from normal in the future.Women should be advised not to start breast self-examination until they have had a clinical examination by their doctor. Thereupon they should start immediately to learn 'what normal feels like' and thus provide a reasonable baseline for monthly re-examination.The number of doctors' clinical examinations so stimulated will yield extra dividends in the discovery of unsuspected lumps in the breast.

    The central aim of this study was to expand a limited body of knowledge on the complex relationship between breast-feeding, co-sleeping, and somatic complaints in early childhood. An opportunity sample of 98 parents from the general population with children aged 18 to 60 months consented to participate in the study. Each parent completed a series of questionnaires measuring somatic complaints, sleep problems, co-sleeping, breast-feeding, and demographic factors. Findings indicated that co-sleeping was associated with increased somatic complaints and that breast-feeding associated with decreased somatic complaints. Co-sleeping also was found to be associated with an increase in sleep problems. Boys demonstrated significantly higher levels of sleep problems than did girls. These findings highlight the relationship between co-sleeping during early childhood, which could have implications for prevention, treatment, and intervention regarding somatic complaints and sleep problems in early childhood.

  6. Early warning of atmospheric regime transitions using transfer operators

    The existence of persistent midlatitude atmospheric regimes, such as blocking events, with time scales larger than 5-10 days and indications of preferred transition paths between them motivates the development of early-warning indicators of regime transitions. Here, we use a barotropic model of the northern midlatitudes winter flow to study such meta-stable regimes. We look at estimates of transfer operators acting on densities evolving on a reduced phase space spanned by the first Empirical Orthogonal Functions of the streamfunction and develop an early-warning indicator of zonal to blocked flow transition. The study of the spectra of transfer operators estimated for different lags reveals a multi-level structure in the flow as well as the effect of memory on the reduced dynamics due to past interactions between the resolved and unresolved variables. The slowest motions in the reduced phase space are thereby found to have time scales larger than 8 days and to behave as Markovian for larger lags. These motions are associated with meta-stable regimes and their transitions and can be detected as almost-invariant sets of the transfer operator. The early-warning indicator is based on the action on an initial density of products of the transfer operators estimated for sufficiently long lags, making use of the semi-group property of these operators and shows relatively good Peirce skill score. From the energy budget of the model, we are able to explain the meta-stability of the regimes and the existence of preferred transition paths as the manifestation of barotropic instability. Finally, even though the model is highly simplified, the skill of the early warning indicator is promising, suggesting that the transfer operator approach can be used in parallel to an operational deterministic model for stochastic prediction or to assess forecast uncertainty.

    During adolescence the breasts undergo rapid growth and development under the influence of sex hormones. Although the hormonal etiology of breast cancer is hypothesized, it remains unknown whether adolescent sex hormones are associated with adult breast density, which is a strong risk factor for breast cancer. Percentage of dense breast volume (%DBV) was measured in 2006 by magnetic resonance imaging in 177 women aged 25-29 years who had participated in the Dietary Intervention Study in Children from 1988 to 1997. They had sex hormones and sex hormone-binding globulin (SHBG) measured in serum collected on one to five occasions between 8 and 17 years of age. Multivariable linear mixed-effect regression models were used to evaluate the associations of adolescent sex hormones and SHBG with %DBV. Dehydroepiandrosterone sulfate (DHEAS) and SHBG measured in premenarche serum samples were significantly positively associated with %DBV (all P trend ≤0.03) but not when measured in postmenarche samples (all P trend ≥0.42). The multivariable geometric mean of %DBV across quartiles of premenarcheal DHEAS and SHBG increased from 16.7 to 22.1 % and from 14.1 to 24.3 %, respectively. Estrogens, progesterone, androstenedione, and testosterone in pre- or postmenarche serum samples were not associated with %DBV (all P trend ≥0.16). Our results suggest that higher premenarcheal DHEAS and SHBG levels are associated with higher %DBV in young women. Whether this association translates into an increased risk of breast cancer later in life is currently unknown.

    Pregnancy, parity and circulating steroid hormone levels are associated with risk of breast cancer, but little is known about hormone concentrations during pregnancy and subsequent breast cancer risk. We evaluated early pregnancy (<140 days gestation) serum estradiol, estrone, progesterone, and testosterone and breast cancer risk in a nested case-control study in the Finnish Maternity Cohort. The cohort includes 98% of pregnancies registered in Finland since 1983. Individuals with samples collected in the first pregnancy leading to a live birth were eligible. Breast cancer cases (n=1,199) were identified through linkage with the Finnish Cancer Registry; 2,281 matched controls were selected using incidence density sampling. Odds ratios were calculated using conditional logistic regression. Hormone concentrations were not associated with breast cancer overall. Estradiol was positively associated with risk of breast cancer diagnosed age <40 (4th vs. 1st quartile OR 1.60 (1.07–2.39); ptrend=0.01), and inversely associated with breast cancer diagnosed at age ≥40 (4th vs. 1st quartile OR 0.71 (0.51–1.00); ptrend=0.02). Elevated concentrations of the steroid hormones were associated with increased risk of estrogen receptor (ER) and progesterone receptor (PR) negative tumors in women age <40 at diagnosis. We observed no association between steroid hormones and ER+/PR+ disease. These data suggest a positive association between high concentrations of early pregnancy steroid hormones and risk of ER−/PR− breast cancer in women diagnosed age <40, and an inverse association for overall breast cancer diagnosed age ≥40. Further research on pregnancy hormones and risk of steroid receptor negative cancers is needed to further characterize this association. PMID:25281720

Methods We apply Cox regression models and a decomposition analysis to the data from the 4,275 women in the Wisconsin Longitudinal Study. Results Higher levels of mothers’ education and early-life family income were associated with a greater risk of breast cancer incidence. The effect of mothers’ education was mediated by women's adult SES and reproductive behaviors. Fathers’ education was related negatively to breast cancer mortality, yet this effect was fully mediated by women's own education.

    Indian women with breast cancer are usually diagnosed in advanced stages leading to poor survival. Improving breast awareness and increasing access to early diagnosis and adequate treatment has been advocated for breast cancer control. We implemented a program to increase awareness on breast cancer and access to its early detection in an occupational health care scheme in Mumbai, India. Breast awareness brochures were mailed annually between June 2013 and June 2016 to a cohort of 22,500 eligible women aged 30-69 years old receiving universal health care from an occupational health care scheme comprising of primary health centres and a referral secondary care hospital in Mumbai. Women with suspected breast cancers were provided with diagnostic investigations and treatment. Socio-demographic information and tumour characteristics were compared between the breast awareness pre-intervention period (Jan 2005-May 2013) and the breast awareness intervention period after four rounds of mailers (June 2013-June 2016). The proportion of women with early tumours and axillary lymph node negative cancers increased from 74% to 81% and 46% to 53% respectively, between the two periods. While the proportion of patients receiving breast conserving surgery increased from 39% to 51%, the proportion receiving chemotherapy decreased from 84% to 56%. Interim results following efforts to improve breast awareness and access to care in a cohort of women in an occupational health care scheme indicate early detection and more conservative treatment of breast cancers. Creating awareness and improving access to care may result in cancer down-staging.

    To evaluate whether chemotherapy is indispensable in elderly patients with early estrogen receptor (ER)-negative breast cancer and diabetes mellitus (DM), the data on 112 patients, ≥70 years of age, with early, operable ER-negative breast cancer who were treated at the Cancer Hospital of Fudan University, Shanghai, China, between 2000 and 2010, were analyzed. The overall survival (OS), disease-free survival (DFS), and breast cancer-specific survival (BCS) were compared. Survival analysis was performed using the Kaplan-Meier method. The Cox proportional hazards model was used to evaluate the prognostic value of DM and chemotherapy for OS, DFS, and BCS. The univariate Cox regression analysis revealed that DM at diagnosis, the number of positive lymph nodes, and radiotherapy were associated with OS, the number of positive lymph nodes, human epidermal growth factor 2 (HER2/neu) status, and radiotherapy were associated with DFS, and the number of positive lymph nodes, tumor size, HER2/neu status, chemotherapy, and radiotherapy were associated with BCS. The subsequent multivariate analysis identified DM at diagnosis (hazard ratio [HR]=3.797; 95% confidence interval [CI], 1.515-9.520; P=0.004) as an independent prognostic factor for OS (with the addition of chemotherapy regimen). Chemotherapy was not an independent prognostic factor for either OS (HR=1.275; 95% CI, 0.614-2.646; P=0.515) or DFS (HR=0.849; 95% CI, 0.445-1.619; P=0.619) when other possible factors that may affect the results were adjusted. In conclusion, chemotherapy was not found to be indispensable for elderly (≥70 years of age) female patients with early ER-negative breast cancer with DM because, particularly in such patients, the treatment of DM may be more important compared with chemotherapy.

    The survival outcomes for women presenting with early breast cancer are influenced by treatment decisions. In Malaysia, survival outcome is generally poor due to late presentation. Of those who present early, many refuse treatment for complementary therapy. This study aimed to explore the decision making experiences of women with early breast cancer. A qualitative study using individual in-depth interviews was conducted to capture the decision making process of women with early breast cancer in Malaysia. We used purposive sampling to recruit women yet to undergo surgical treatment. A total of eight participants consented and were interviewed using a semi-structured interview guide. These women were recruited from a period of one week after they were informed of their diagnoses. A topic guide, based on the Ottawa decision support framework (ODSF), was used to facilitate the interviews, which were audio recorded, transcribed and analysed using a thematic approach. We identified four phases in the decision-making process of women with early breast cancer: discovery (pre-diagnosis); confirmatory ('receiving bad news'); deliberation; and decision (making a decision). These phases ranged from when women first discovered abnormalities in their breasts to them making final surgical treatment decisions. Information was vital in guiding these women. Support from family members, friends, healthcare professionals as well as survivors also has an influencing role. However, the final say on treatment decision was from themselves. The treatment decision for women with early breast cancer in Malaysia is a result of information they gather on their decision making journey. This journey starts with diagnosis. The women's spouses, friends, family members and healthcare professionals play different roles as information providers and supporters at different stages of treatment decisions. However, the final treatment decision is influenced mainly by women's own experiences, knowledge

    As there is a risk for relapse in early breast cancer, especially at 1-3 years post surgery, the need for adjuvant therapy is clear. In terms of disease-free survival, aromatase inhibitors have emerged as superior to tamoxifen for the adjuvant treatment of hormone-sensitive breast cancer in several Phase III clinical trials. Of these trials, the Breast International Group (BIG) 1-98 trial stands out as unique in design, as it is the only trial to address whether an aromatase inhibitor is more effective as initial adjuvant therapy or as sequential therapy with an aromatase inhibitor and tamoxifen in either order and in rigor of end points and safety evaluations. When compared with tamoxifen, letrozole has been shown to significantly reduce recurrence risk in the overall population by 19% and also significantly reduced recurrence risk in the patient subgroups at increased risk: node-positive and previously chemotherapy-treated patients. Letrozole is the only aromatase inhibitor to demonstrate a significant 27% reduction in the risk of distant metastases (p = 0.001) in the clinically relevant, hormone receptor-positive population in the initial adjuvant setting. Recent results also suggest that letrozole in particular reduces the risk of distant metastases early on after initial surgery for breast cancer. This is important, as early distant metastatic events compose the majority of early recurrences and are a well-recognized predictor of breast cancer death. Letrozole has been found to be well tolerated in the initial adjuvant treatment setting, and these data have been confirmed by long-term safety data from the monotherapy analysis in the BIG 1-98 study. Thus far, the results from the BIG 1-98 trial provide clear support for the use of letrozole in the initial adjuvant treatment of breast cancer. Future studies will provide the definitive answer to questions of which initial adjuvant therapy is superior (i.e., anastrozole or letrozole) and information as to the

    Wide local excision followed by external beam radiation therapy (EBRT) to the whole breast has become the standard of care for most patients with localised 'early' breast cancer in the UK, Europe, and the USA. Local relapse rates are low, and overall survival figures have improved during the past decade, with the advent of more effective systemic endocrine- and chemo-therapy. A policy of EBRT for every patient undergoing breast conserving surgery (BCS) is however associated with a number of practical difficulties, acute radiation side effects and longer term toxicity, all of which detract from the obvious benefits of EBRT. In addition, with a disease as common as early breast cancer and a treatment programme typically requiring sophisticated radiation planning and many fractions of treatment, the policy of BCS plus EBRT has enormous resource implications within departments of oncology, greatly contributing to lengthy pre-treatment delays. For all these reasons, we and others have developed an increasing interest in techniques of partial breast irradiation, with an emphasis in our own Department on the emerging technique of intra-operative radiotherapy (IORT), which we initially employed as a boost to the tumour bed for use in conjunction with EBRT to the whole breast. To test the possibility of replacing the whole of the EBRT 3-6 week programme by a single application of IORT at the time of surgery, we and others have commenced a large scale prospectively randomised clinical trail in selected patients. Nine international centres are currently participating, and 350 patients have now been randomised to receive either IORT as part of the initial surgical excision or conventional EBRT with a pragmatic dose policy according to the preference of the contributing centre. The majority of patients undergoing IORT receive this at the time of initial surgery but it is also permissible within the trial programme to randomise suitable patients after the excised specimen has

    Fourteen patients whose augmented or reconstructed breasts were treated with radiation therapy were analyzed. Silicone gel implants were used in 13 patients and free-injected silicone in one patient. The total radiation dose ranged from 4400 to 6200 cGy using tangential photon fields or an en face electron field by megavoltage equipment. In several cases, electron boost radiation was added to the tumor bed. The majority of the patients tolerated therapy well with minimal transient skin reactions; only three patients required a treatment break secondary to moist desquamation. Three patients developed documented implant encapsulation, although the majority retained good to excellent cosmesis. In summary, when breast carcinoma arises in the augmented or reconstructed breast, conservative management (i.e., limited surgery and definitive irradiation) is feasible without compromising the therapy or the cosmetic result. Thus, conservative management should be offered as an option to patients who are interested in breast prosthesis conservation.

    Background Premenopausal breast cancer with a triple-negative phenotype (TNBC) has been associated with inferior locoregional recurrence free survival (LRFS) and overall survival (OS) after breast conserving surgery (BCS). The aim of this study is to analyze the association between age, subtype, and surgical treatment on survival in young women (≤40 years) with early breast cancer in a population with a high rate of breast cancer in young women. Methods Three hundred thirty-two patients ≤40 years old with stage I-II invasive breast cancer who underwent surgery at a single institution between 1998 and 2012 were identified retrospectively. Uni- and multivariate analysis evaluated predictors of LRFS, OS, and disease free survival (DFS). Results Most patients (64.2%) underwent BCS. Mean age and follow-up time were 35 (25 ± 3.61) years, and 72 months (range, 24–252), respectively. In multivariate analysis, multicentricity/multifocality and young age (<35 years) independently predicted for poorer DFS and OS. Those aged 35–40 years had higher LRFS and DFS than those <35 in the mastectomy group (p=0.007 and p=0.039, respectively). Patients with TNBC had lower OS compared with patients with luminal A subtype (p=0.042), and those who underwent BCS had higher OS than patients after mastectomy (p=0.015). Conclusion Young age (< 35 years) is an independent predictor of poorer OS and DFS as compared with ages 35–40, even in countries with a lower average age of breast cancer presentation. In addition, TNBC in the young predicts for poorer OS. BCS can be performed in young patients with TNBC, despite their poorer overall survival. PMID:27433412

    As an organized screening program, the national Breast and Cervical Cancer Early Detection Program (BCCEDP) was launched in the early 1990s to improve breast cancer outcomes among underserved women. To analyze the impact of the BCCEDP on breast cancer outcomes in Ohio, this study compared cancer stages and mortality across BCCEDP participants, Medicaid beneficiaries, and "all others." This study linked data across the Ohio Cancer Incidence Surveillance System, Medicaid, the BCCEDP database, death certificates, and the US Census and identified 26,426 women aged 40 to 64 years who had been diagnosed with incident invasive breast cancer during the years 2002-2008 (deaths through 2010). The study groups were as follows: BCCEDP participants (1-time or repeat users), Medicaid beneficiaries (women enrolled in Medicaid before their cancer diagnosis [Medicaid/prediagnosis] or around the time of their cancer diagnosis [Medicaid/peridiagnosis]), and all others (women identified as neither BCCEDP participants nor Medicaid beneficiaries). The outcomes included advanced-stage cancer at diagnosis and mortality. A multivariable logistic and survival analysis was conducted to examine the independent association between the BCCEDP and Medicaid status and the outcomes. The percentage of women presenting with advanced-stage disease was highest among women in the Medicaid/peridiagnosis group (63.4%) and lowest among BCCEDP repeat users (38.6%). With adjustments for potential confounders and even in comparison with Medicaid/prediagnosis beneficiaries, those in the Medicaid/peridiagnosis group were twice as likely to be diagnosed with advanced-stage disease (adjusted odds ratio, 2.20; 95% confidence interval, 1.83-2.66). Medicaid/peridiagnosis women are at particularly high risk to be diagnosed with advanced-stage disease. Efforts to reduce breast cancer disparities must target this group of women before they present to Medicaid. Cancer 2017;123:3097-106. © 2017 American Cancer Society

    Introduction The ability to screen blood of early stage operable breast cancer patients for circulating tumour cells is of potential importance for identifying patients at risk of developing distant relapse. We present the results of a study of the efficacy of the immunobead RT-PCR method in identifying patients with circulating tumour cells. Results Immunomagnetic enrichment of circulating tumour cells followed by RT-PCR (immunobead RT-PCR) with a panel of five epithelial specific markers (ELF3, EPHB4, EGFR, MGB1 and TACSTD1) was used to screen for circulating tumour cells in the peripheral blood of 56 breast cancer patients. Twenty patients were positive for two or more RT-PCR markers, including seven patients who were node negative by conventional techniques. Significant increases in the frequency of marker positivity was seen in lymph node positive patients, in patients with high grade tumours and in patients with lymphovascular invasion. A strong trend towards improved disease free survival was seen for marker negative patients although it did not reach significance (p = 0.08). Conclusion Multi-marker immunobead RT-PCR analysis of peripheral blood is a robust assay that is capable of detecting circulating tumour cells in early stage breast cancer patients. PMID:19500345

    In Malawi, routine breast cancer screening is not available and little is known about women's preferences regarding early detection services. Discrete choice experiments are increasingly used to reveal preferences about new health services; however, selecting appropriate attributes that describe a new health service is imperative to ensure validity of the choice experiment. To identify important factors that are relevant to Malawian women's preferences for breast cancer detection services and to select attributes and levels for a discrete choice experiment in a setting where both breast cancer early detection and choice experiments are rare. We reviewed the literature to establish an initial list of potential attributes and levels for a discrete choice experiment and conducted qualitative interviews with health workers and community women to explore relevant local factors affecting decisions to use cancer detection services. We tested the design through cognitive interviews and refined the levels, descriptions, and designs. Themes that emerged from interviews provided critical information about breast cancer detection services, specifically, that breast cancer interventions should be integrated into other health services because asymptomatic screening may not be practical as an individual service. Based on participants' responses, the final attributes of the choice experiment included travel time, health encounter, health worker type and sex, and breast cancer early detection strategy. Cognitive testing confirmed the acceptability of the final attributes, comprehension of choice tasks, and women's abilities to make trade-offs. Applying a discrete choice experiment for breast cancer early detection was feasible with appropriate tailoring for a low-income, low-literacy African setting.

    This article presents the application of machine learning algorithms for early detection of breast cancer on the basis of thermographic images. Supervised learning model: Support vector machine (SVM) and Sequential Minimal Optimization algorithm (SMO) for the training of SVM classifier were implemented. The SVM classifier was included in a client-server application which enables to create a training set of examinations and to apply classifiers (including SVM) for the diagnosis and early detection of the breast cancer. The sensitivity and specificity of SVM classifier were calculated based on the thermographic images from studies. Furthermore, the heuristic method for SVM's parameters tuning was proposed.

    To describe the impairments of upper body and limbs, activity limitations and participation restrictions 6 and 12 months after operation for breast cancer and to examine the impact of impairments on activity limitations. A prospective survey 6 and 12 months after operation. Ninety-six breast cancer patients. A questionnaire for assessing the impairments, activity limitations and participation restrictions was developed. The most common impairments 6 months after operation were breast and axilla scar tightness, axilla oedema and neck-shoulder pain. At 12-month follow-up the breast scar tightness (p=0.008) and axilla oedema (p=0.023) decreased, and limb ache (p=0.005) increased significantly. The most limiting impairments were axilla oedema and limb numbness 6 months after operation, and at 12-month follow-up axilla oedema. Lifting, carrying and reaching out caused worsening of impairments to more than half of the respondents at 6-month follow-up. Regression analysis showed that many impairments together were determinants of activity limitations and sleep impairment. Participation restrictions were constant. Respondents had not given up participation in activities in the home, but some had abandoned leisure activities and felt that their work ability had decreased. Impairments and their impact on activities were frequent and constant. There is an urgent need for developing rehabilitation protocols for breast cancer patients.

    The early growth of micrometastatic breast cancer in the brain often occurs through vessel co-option and is independent of angiogenesis. Remodeling of the existing vasculature is an important step in the evolution of co-opting micrometastases into angiogenesis-dependent solid tumor masses. The purpose of this study was to determine whether phase contrast MRI, an intrinsic source of contrast exquisitely sensitive to the magnetic susceptibility properties of deoxygenated hemoglobin, could detect vascular changes occurring independent of angiogenesis in a rat model of breast cancer metastases to the brain. Twelve nude rats were administered 10(6) MDA-MB-231BRL 'brain-seeking' breast cancer cells through intracardiac injection. Serial, multiparametric MRI of the brain was performed weekly until metastatic disease was detected. The results demonstrated that images of the signal phase (area under the receiver operating characteristic curve, 0.97) were more sensitive than T(2)* gradient echo magnitude images (area under the receiver operating characteristic curve, 0.73) to metastatic brain lesions. The difference between the two techniques was probably the result of the confounding effects of edema on the magnitude of the signal. A region of interest analysis revealed that vascular abnormalities detected with phase contrast MRI preceded tumor permeability measured with contrast-enhanced MRI by 1-2  weeks. Tumor size was correlated with permeability (R(2)= 0.23, p < 0.01), but phase contrast was independent of tumor size (R(2)= 0.03). Histopathologic analysis demonstrated that capillary endothelial cells co-opted by tumor cells were significantly enlarged, but less dense, relative to the normal brain vasculature. Although co-opted vessels were vascular endothelial growth factor-negative, vessels within larger tumor masses were vascular endothelial growth factor-positive. In conclusion, phase contrast MRI is believed to be sensitive to vascular remodeling in co

    The relationship of breast cancer to early reproductive development and height suggests that fetal and childhood nutrition may be important in its aetiology. Caloric restriction sufficient to reduce adult height may reduce breast cancer risk. During World War II (WWII) there was a marked reduction in average caloric intake in Norway that resulted in greater nutritional diversity. We hypothesized that a positive association between height and risk of breast cancer would be stronger among women who were born during this period than among women born before or after the war. A total of 25 204 Norwegian women were followed up for approximately 11 years, and 215 incident cases of breast cancer were registered. We found the strongest positive association between height and breast cancer among women born during WWII: women in the tallest tertile (>167 cm) had a relative risk of 2.5 (95% confidence interval = 1.2–5.5) compared with the shortest (≤ 162 cm). Among women born before or after the war we found no clear association with height. The association with height in the WWII cohort may imply a role for early nutrition in breast cancer aetiology. © 2001 Cancer Research Campaignhttp://www.bjcancer.com PMID:11592765

    The purpose of this study was to evaluate the differences in stage upon diagnosis, adherence to adjuvant treatment, and recurrence between rural and urban patients with early breast cancer. This retrospective study included 3640 patients with primary breast cancer recruited from 2000 to 2009. Patients who developed recurrence or metastasis were verified by adequate diagnostic imaging modalities and pathology. The χ(2) test was used to compare groups with respect to variables (recurrence and clinicopathologic features). A multivariable Cox proportional hazard regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for breast cancer recurrence risk. Compared with tumors in urban patients, those in rural patients showed higher histologic grade, larger size, more lymphatic metastasis, and higher Ki-67 index; therapy adherence was strongly associated with recurrence in both. Compared with urban patients, the female rural patients had a higher recurrence rate. However, no significant difference in recurrence rates was observed between urban and rural patients following guideline adherence. The results of our study suggest that the later stage upon diagnosis and nonadherence to treatment contribute toward worse breast cancer outcomes among rural patients with breast cancer. Adherence to needed adjuvant therapy could decrease recurrence rates for rural patients with early breast cancer. Copyright © 2016 Elsevier Inc. All rights reserved.

  10. Novel Multistatic Adaptive Microwave Imaging Methods for Early Breast Cancer Detection

    Multistatic adaptive microwave imaging (MAMI) methods are presented and compared for early breast cancer detection. Due to the significant contrast between the dielectric properties of normal and malignant breast tissues, developing microwave imaging techniques for early breast cancer detection has attracted much interest lately. MAMI is one of the microwave imaging modalities and employs multiple antennas that take turns to transmit ultra-wideband (UWB) pulses while all antennas are used to receive the reflected signals. MAMI can be considered as a special case of the multi-input multi-output (MIMO) radar with the multiple transmitted waveforms being either UWB pulses or zeros. Since the UWB pulses transmitted by different antennas are displaced in time, the multiple transmitted waveforms are orthogonal to each other. The challenge to microwave imaging is to improve resolution and suppress strong interferences caused by the breast skin, nipple, and so forth. The MAMI methods we investigate herein utilize the data-adaptive robust Capon beamformer (RCB) to achieve high resolution and interference suppression. We will demonstrate the effectiveness of our proposed methods for breast cancer detection via numerical examples with data simulated using the finite-difference time-domain method based on a 3D realistic breast model.

    Molecular pathways determining the malignant potential of premalignant breast lesions remain unknown. In this study, alterations in DNA methylation levels were monitored during benign, premalignant and malignant stages of ductal breast cancer development. To study epigenetic events during breast cancer development, four genomic biomarkers (Methylated-IN-Tumour (MINT)17, MINT31, RARβ2 and RASSF1A) shown to represent DNA hypermethylation in tumours were selected. Laser capture microdissection was employed to isolate DNA from breast lesions, including normal breast epithelia (n=52), ductal hyperplasia (n=23), atypical ductal hyperplasia (n=31), ductal carcinoma in situ (DCIS, n=95) and AJCC stage I invasive ductal carcinoma (IDC, n=34). Methylation Index (MI) for each biomarker was calculated based on methylated and unmethylated copy numbers measured by Absolute Quantitative Assessment Of Methylated Alleles (AQAMA). Trends in MI by developmental stage were analysed. Methylation levels increased significantly during the progressive stages of breast cancer development; P-values are 0.0012, 0.0003, 0.012, <0.0001 and <0.0001 for MINT17, MINT31, RARβ2, RASSF1A and combined biomarkers, respectively. In both DCIS and IDC, hypermethylation was associated with unfavourable characteristics. DNA hypermethylation of selected biomarkers occurs early in breast cancer development, and may present a predictor of malignant potential.

    Breast cancer represents a significant health problem because of its high prevalence. Tests like mammography, which are used abundantly for the detection of breast cancer, suffer from serious limitations. Mammography correctly detects malignancy about 80-90% of the times, failing in places when (1) the tumor is small at early stage, (2) breast tissue is dense or (3) in women of less than 40 years. Serum-based detection of biomarkers involves risk of disease transfer, along with other concerns. These techniques compromise in the early detection of breast cancer. Early detection of breast cancer is a crucial factor to enhance the survival rate of patient. Development of regular screening tests for early diagnosis of breast cancer is a challenge. This review highlights the design of a handy and household biosensor device aimed for self-screening and early diagnosis of breast cancer. The design makes use of salivary autoantibodies for specificity to develop a noninvasive procedure, breast cancer specific biomarkers for precision for the development of device, and biosensor technology for sensitivity to screen the early cases of breast cancer more efficiently.

    The narrative operative report represents the traditional means by which breast cancer surgery has been documented. Previous work has established that omissions occur in narrative operative reports produced in an academic setting. The goal of this study was to determine the completeness of breast cancer narrative operative reports produced in a community care setting and to explore the effect of a surgeon's case volume and years in practice on the completeness of these reports. A standardized retrospective review of operative reports produced over a consecutive 2 year period was performed using a set of procedure-specific elements identified through a review of the relevant literature and work done locally. 772 operative reports were reviewed. 45% of all elements were completely documented. A small positive trend was observed between case volume and completeness while a small negative trend was observed between years in practice and completeness. The dictated narrative report inadequately documents breast cancer surgery irrespective of the recording surgeon's volume or experience. An intervention, such as the implementation of synoptic reporting, should be considered in an effort to maximize the utility of the breast cancer operative report. Copyright © 2017.

    Obesity is a well known risk factor for breast cancer recurrence and poor prognosis. We studied the effect of body mass index (BMI) on recurrence pattern in early breast cancer patients. This retrospective cross-sectional study analyzed the data of 2731 early stage breast cancer patients. Patients who had metastatic disease at the time of diagnosis and with unknown BMI values were excluded from study (N=276). Patients were classified into three BMI categories: normal body weight, overweight, and obese. The recurrent/metastatic sites of patients were grouped in 8 categories: local, contralateral, lymph node, bone, lung, liver, brain and others. The association between first relapse site of early breast cancer patients and BMI categories were evaluated. The median patient age was 48 years (range 18-92). The median follow up time was 40 months (range 1-284). During follow-up, 469 (17.1%) patients developed recurrence and/or metastasis. Of 2455 total patients, 853 (34.6%) were classified as having normal weight, 898 (36.2%) were overweighted and 704 (29.2%) were obese. In the whole patient group no relation between metastatic sites and BMI groups was noticed. The first primary metastatic sites were also not associated with BMI groups in pre and postmenopausal subpopulations. In obese patients, disease free survival (DFS) was shorter compared to normal weighted patients, but the difference was not significant. There was no significant difference between site-specific DFS in relation to BMI categorization. Obese and overweighted patients had significantly shorter overall survival (OS) compared to the normal-weight group (p=0.003). Although obesity had no effect on recurrence pattern of early breast cancer patients, obese early breast cancer patients had shorter OS compared to their normal-weight counterparts.

  16. Hypofractionated radiation therapy in the treatment of early-stage breast cancer.

    PubMed

    Freedman, Gary M

    2012-02-01

    Hypofractionated radiation refers to the use of fewer, larger-dose radiation treatments that are usually given over a shorter time period compared to conventional radiation fraction sizes. Randomized trials of hypofractionated whole breast irradiation (WBI) have demonstrated comparable outcomes as conventional fractionation. For a higher-risk population for local recurrence, a phase 3 trial by the Radiation Therapy Oncology Group (RTOG) is currently studying hypofractionated WBI with a concurrent tumor bed boost over 3 weeks. Accelerated partial breast irradiation limits radiation to the region of the tumor bed for 1-3 weeks and is the subject of an ongoing randomized trial by the National Surgical Breast and Bowel Project and RTOG. Questions remain for hypofractionation about optimal patient selection, radiation techniques, and the risk of late toxicity. But results from current trials could make hypofractionation more widely accepted for patients with early-stage breast cancer.

    Objective: Hormones have been implicated as modulators of cognitive functioning. For instance, results of our previous work in women with breast cancer showed that cognitive impairment was more severe and involved more memory domains in those who received adjuvant tamoxifen therapy compared with women who received chemotherapy alone or no adjuvant therapy. Recently aromatase inhibitors such as anastrozole have been used in lieu of tamoxifen for the adjuvant treatment of postmenopausal women with hormone receptor–positive, early-stage breast cancer. Plasma estrogen levels are significantly lower in women who receive anastrozole compared with those who receive tamoxifen. We hypothesized, therefore, that anastrozole would have a more profound effect on cognitive function than tamoxifen, a mixed estrogen agonist/antagonist. Design: To test this hypothesis we compared cognitive function in women with early-stage breast cancer who received tamoxifen with those who received anastrozole therapy in a cross-sectional study. We evaluated cognitive function, depression, anxiety, and fatigue in 31 postmenopausal women with early-stage breast cancer who were between the ages of 21 and 65 years and treated with tamoxifen or anastrozole for a minimum of 3 months. Results: The results showed that women who received anastrozole had poorer verbal and visual learning and memory than women who received tamoxifen. Conclusions: Additional, prospective studies are needed to validate and confirm the changes in cognitive function associated with hormone therapy for breast cancer. PMID:17898668

    Breast cancer is a major health problem that affects one in eight women worldwide. As such, detecting breast cancer at an early stage anticipates better disease outcome and prolonged patient survival. Extensive research has shown that microRNA (miRNA) are dysregulated at all stages of breast cancer. miRNA are a class of small noncoding RNA molecules that can modulate gene expression and are easily accessible and quantifiable. This review highlights miRNA as diagnostic, prognostic and therapy predictive biomarkers for early breast cancer with an emphasis on the latter. It also examines the challenges that lie ahead in their use as biomarkers. Noteworthy, this review addresses miRNAs reported in patients with early breast cancer prior to chemotherapy, radiotherapy, surgical procedures or distant metastasis (unless indicated otherwise). In this context, miRNA that are mentioned in this review were significantly modulated using more than one statistical test and/or validated by at least two studies. A standardized protocol for miRNA assessment is proposed starting from sample collection to data analysis that ensures comparative analysis of data and reproducibility of results.

  1. Is adjuvant therapy for older patients with node (-) early breast cancer cost-effective?

    Node (-) breast cancer represents over 60% of cases in older women and currently there is a debate whether adjuvant therapy for these women is cost-effective. Evaluate if adjuvant treatment for early-stage node (-) breast cancer with hormone therapy, chemotherapy, or combination therapy is cost-effective in older patients. Decision-analysis modeling using life tables integrated the cost of treatment in dollars and impact in length and quality of life. The primary data sources were meta-analysis from the Early Breast Cancer Trialists' Collaborative Group and the Red Book Average Wholesale Price for drugs. The incremental cost-effectiveness of different treatment strategies were then compared and mapped graphically. Adjuvant therapy is cost-effective in 65-year-old women with early breast cancer. In a 75-year-old estrogen receptor, ER (+) patient, hormone therapy, specifically tamoxifen, is cost-effective, 19,530 dollars/QALY. In a 75-year-old ER (-) the use of chemotherapy (AC or CMF) or 85-year-old ER (+) the use of hormone therapy was only marginally cost-effective, 54,000-76,000 dollars/QALY, only if efficacy was assumed to be age-insensitive (similar to a 65-year-old woman). Decision-analytic models can help policy makers who are faced with decisions about whether to support adjuvant therapy in older breast cancer patients and also outline the important parameters that need to be considered in such a decision.

  2. Awareness that early cancer lump is painless could decrease breast cancer mortality in developing countries.

    PubMed

    Garg, Pankaj

    2016-06-10

    There are several factors which contribute to patients' reporting late to healthcare facility even after detecting the breast lump (patient delay). Amongst these, one of the important factors in low- and middle-income countries is lack of awareness that early cancer lump is painless (ECLIPs). Pain is often taken as a danger sign and absence of pain is often not taken seriously. The studies have shown that up to 98% of women in low-income countries are unaware that a painless lump could be a warning sign of early breast cancer. This fact is significant because this could be one of the prime reasons for the women having discovered a painless lump in the breast, accidentally or by breast self-examination, presume it to be harmless and don't report early to health care facility. Therefore, creating awareness about ECLIPs could be an effective strategy to reduce mortality due to breast cancer in low- and middle-income countries. Moreover, unlike modifying risk factors which requires long term behavior modification, creating awareness about ECLIPs is easy and cost effective.

  3. Aromatase inhibitors and their future role in post-menopausal women with early breast cancer.

    PubMed Central

    Lønning, P. E.

    1998-01-01

    Anastrozole is the first aromatase inhibitor to show a significant survival advantage over megestrol acetate in post-menopausal women with advanced breast cancer. The rationale for extending the use of aromatase inhibitors to the treatment of early breast cancer is based on the efficacy observed in the advanced setting, combined with good tolerability and a convenient dosing regimen. Furthermore, oestrogen deprivation by ovarian ablation (similar to oestrogen antagonism with tamoxifen) is already established as an effective adjuvant treatment in premenopausal women with modality breast cancer. Anastrozole produces a profound suppression of plasma oestrogen levels which is greater than that obtained with earlier aromatase inhibitors (formestane, aminoglutethimide) or megestrol acetate. This could account for the differences in clinical efficacy seen between anastrozole and megestrol acetate. In terms of benefits over other endocrine agents, anastrozole causes significantly less weight gain than megestrol acetate; it does not have the partial agonist activity of tamoxifen, and is unlikely to lead to tumour stimulation in patients resistant to tamoxifen or to exert proliferative effects on the endometrium. The lack of oestrogen agonist activity, however, may possibly have detrimental effects on bone mineral density and blood lipid profile. Current clinical trials are investigating the efficacy and safety of anastrozole in the early breast cancer setting. The results of these trials will help to determine whether anastrozole has any benefits over tamoxifen, the current treatment of choice in post-menopausal women with early breast cancer.

    We describe an early operant conditioning chamber fabricated by Harvard University instrument maker Ralph Gerbrands and shipped to Japan in 1952 in response to a request of Professor B. F. Skinner by Japanese psychologists. It is a rare example, perhaps the earliest still physically existing, of such a chamber for use with pigeons. Although the overall structure and many of the components are similar to contemporary pigeon chambers, several differences are noted and contrasted to evolutionary changes in this most important laboratory tool in the experimental analysis of behavior. The chamber also is testimony to the early internationalization of behavior analysis.

    2008-11-01

    Purpose: To determine the risk of regional-nodal recurrence in patients with early-stage, invasive breast cancer, with clinically negative axillary nodes, who were treated with breast-conserving surgery, 'high tangential' breast radiotherapy, and hormonal therapy, without axillary surgery or the use of a separate nodal radiation field. Methods and Materials: Between September 1998 and November 2003, 74 patients who were {>=}55 years of age with Stage I-II clinically node-negative, hormone-receptor-positive breast cancer underwent tumor excision to negative margins without axillary surgery as a part of a multi-institutional prospective study. Postoperatively, all underwent high-tangential, whole-breast radiotherapy with a boost to the tumor bed, followed by 5 years of hormonal therapy. Results: For the 74 patients enrolled, the median age was 74.5 years, and the median pathologic tumor size was 1.2 cm. Lymphatic vessel invasion was present in 5 patients (7%). At a median follow-up of 52 months, no regional-nodal failures or ipsilateral breast recurrences had been identified (95% confidence interval, 0-4%). Eight patients died, one of metastatic disease and seven of other causes. Conclusion: In this select group of mainly older patients with early-stage hormone-responsive breast cancer and clinically negative axillary nodes, treatment with high-tangential breast radiotherapy and hormonal therapy, without axillary surgery, yielded a low regional recurrence rate. Such patients might be spared more extensive axillary treatment (axillary surgery, including sentinel node biopsy, or a separate nodal radiation field), with its associated time, expense, and morbidity.

    Purpose Accelerated partial breast irradiation (APBI) is an accepted treatment option in breast-conserving therapy for early stage breast cancer. However, data regarding outcomes of patients treated with multi-lumen catheter systems who have existing breast implants is limited. The purpose of this study was to report treatment parameters, outcomes, and possible dosimetric correlation with cosmetic outcome for this population of patients at our institution. Material and methods We report the treatment and outcome of seven consecutive patients with existing breast implants and early stage breast cancer who were treated between 2009 and 2013 using APBI following lumpectomy. All patients were treated twice per day for five days to a total dose of 34 Gy using a high-dose-rate 192Ir source. Cosmetic outcomes were evaluated using the Harvard breast cosmesis scale, and late toxicities were reported using the Radiation Therapy Oncology Group (RTOG) late radiation morbidity schema. Results After a mean follow-up of 32 months, all patients have remained cancer free. Six out of seven patients had an excellent or good cosmetic outcome. There were no grade 3 or 4 late toxicities. The average total breast implant volume was 279.3 cc, received an average mean dose of 12.1 Gy, and a maximum dose of 234.1 Gy. The average percentage of breast implant volume receiving 50%, 75%, 100%, 150%, and 200% of the prescribed dose was 15.6%, 7.03%, 4.6%, 1.58%, and 0.46%, respectively. Absolute volume of breast implants receiving more than 50% of prescribed dose correlated with worse cosmetic outcomes. Conclusions Accelerated partial breast irradiation using a multi-lumen applicator in patients with existing breast implants can safely be performed with promising early clinical results. The presence of the implant did not compromise the ability to achieve dosimetric criteria; however, dose to the implant and the irradiated implant volume may be related with worse cosmetic outcomes.

    Purpose: A retrospectivechart review was conducted to determine whether the time interval from breast-conserving surgery to breast irradiation (surgery-radiation therapy interval) in early stage node-negative breast cancer had any detrimental effects on recurrence rates. Methods and Materials: There were 566 patients with T1 to T3, N0 breast cancer treated with breast-conserving surgery and breast irradiation and without adjuvant systemic treatment between 1985 and 1992. The surgery-to-radiation therapy intervals used for analysis were 0 to 8 weeks (201 patients), >8 to 12 weeks (233 patients), >12 to 16 weeks (91 patients), and >16 weeks (41 patients). Kaplan-Meier estimates of time to local recurrence, disease-free survival, distant disease-free survival, cause-specific survival, and overall survival rates were calculated. Results: Median follow-up was 17.4 years. Patients in all 4 time intervals were similar in terms of characteristics and pathologic features. There were no statistically significant differences among the 4 time groups in local recurrence (P=.67) or disease-free survival (P=.82). The local recurrence rates at 5, 10, and 15 years were 4.9%, 11.5%, and 15.0%, respectively. The distant disease relapse rates at 5, 10, and 15 years were 10.6%, 15.4%, and 18.5%, respectively. The disease-free failure rates at 5, 10, and 15 years were 20%, 32.3%, and 39.8%, respectively. Cause-specific survival rates at 5, 10, and 15 years were 92%, 84.6%, and 79.8%, respectively. The overall survival rates at 5, 10, and 15 years were 89.3%, 79.2%, and 66.9%, respectively. Conclusions: Surgery-radiation therapy intervals up to 16 weeks from breast-conserving surgery are not associated with any increased risk of recurrence in early stage node-negative breast cancer. There is a steady local recurrence rate of 1% per year with adjuvant radiation alone.

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

    Purpose: Several recent series evaluating external beam accelerated partial breast irradiation (PBI) have reported adverse cosmetic outcomes, possibly related to large volumes of normal tissue receiving near-prescription doses. We hypothesized that delivery of external beam PBI in a single fraction to the preoperative tumor volume would be feasible and result in a decreased dose to the uninvolved breast compared with institutional postoperative PBI historical controls. Methods and Materials: A total of 17 patients with unifocal Stage T1 breast cancer were identified. Contrast-enhanced subtraction magnetic resonance images were loaded into an Eclipse treatment planning system and used to define the target volumes. A 'virtual plan' was created using four photon beams in a noncoplanar beam arrangement and optimized to deliver 15 Gy to the planning target volume. Results: The median breast volume was 1,713 cm{sup 3} (range: 1,014-2,140), and the median clinical target volume was 44 cm{sup 3} (range: 26-73). In all cases, 100% of the prescription dose covered 95% of the clinical target volume. The median conformity index was 0.86 (range: 0.70-1.12). The median percentage of the ipsilateral breast volume receiving 100% and 50% of the prescribed dose was 3.8% (range: 2.2-6.9) and 13.3% (range: 7.5-20.8) compared with 18% (range: 3-42) and 53% (range: 24-65) in the institutional historical controls treated with postoperative external beam PBI (p = .002). The median maximum skin dose was 9 Gy. The median dose to 1 and 10 cm{sup 3} of skin was 6.7 and 4.9 Gy. The doses to the heart and ipsilateral lung were negligible. Conclusion: Preoperative PBI resulted in a substantial reduction in ipsilateral breast tissue dose compared with postoperative PBI. The skin dose appeared reasonable, given the small volumes. A prospective Phase I trial evaluating this technique is ongoing.

    To document the use of adjuvant regional irradiation after breast-conserving therapy for early stage breast cancer by Canadian radiation oncologists and to identify the factors influencing their clinical decisions. We conducted a survey to assess the above aims. In April 2008, a questionnaire was sent to 167 members of the Canadian and Quebec Associations of Radiation Oncologists with interest in breast cancer management. The answers were obtained through a dedicated website, which collected the raw data collected for analysis. In total, 67 radiation oncologists completed the survey, corresponding to a 40% response rate. Most respondents were experienced and high-volume providers. We identified several areas of variation in the decision-making regarding regional lymph node irradiation after breast-conserving therapy. Regarding the decision to combine regional nodal irradiation with irradiation of the breast, the number of positive nodes after axillary dissection (1-3 vs > or =4) was a crucial determinant. For patients with between one and three positive nodes and a nodal ratio of 50%, most respondents added regional irradiation. Similarly, the same nodal ratio of 50% was the main factor for inclusion of the axillary nodal region in the radiation field. However, few radiation oncologists have chosen to include the internal mammary chain in their treatment plan. The number of positive lymph nodes, the nodal ratio, the number of lymph nodes removed and the presence of extracapsular extension were the primary self-reported factors that directed the decision to offer regional radiotherapy. This survey showed that there is a wide variation of practices among radiation oncologists in Canada. These results support the need for treatment guidelines and provide guidance on which factors should be included in a decision-making algorithm. Copyright (c) 2009 The Royal College of Radiologists.

    Phyllodes tumor is an extremely rare tumor of the breast. It occurs in females in the third and fourth decades. The difficulty in distinguishing between phyllodes tumors and benign fibroadenoma may lead to misdiagnosis. Lymph node involvement is rarely described in phyllodes tumors; for this reason, sentinel node biopsy may be warranted. We present a case of a 33-year-old woman affected by huge tumor of the right breast with ulceration in the skin with a rapid tumor growth and with omolateral axillary metastasis.

    Abstract The present study aimed to investigate risk factors for early onset breast cancer that are related to lifestyle and psychological stress. A comparative case–control study was performed among patients from the Department of Breast Surgery in Shanghai Cancer Center of Fudan University. The information regarding risk factors associated with the development of early onset breast cancer was collected using a questionnaire in a face-to-face interview. The distribution of the risk factors associated with the development of early onset breast cancer between the patient group and the control group was analyzed with logistic regression. A total of 582 cases of young patients (≤40 years old) with breast cancer and 540 controls of young patients (≤40 years old) with benign breast disease were included in this study. The risk factors for breast cancer in young women include age at first birth (odds ratio [OR] = 0.93, 95% confidence interval [CI]: 0.88–0.98), history of breast cancer in an immediate family member (OR = 2.36, 95% CI: 1.14–4.89), history of genital surgery (OR = 2.11, 95% CI: 1.16–3.82), active and passive smoking in daily life or the environment (OR = 1.64, 95% CI: 1.19–2.25), weekly intake of soy products (OR = 1.24, 95% CI: 1.02–1.49), use of household cooking oil (OR = 2.04, 95% CI: 1.04–4.00), disharmonious marital status (OR = 1.16, 95% CI: 1.06–1.26), frequent depression (OR = 1.32, 95% CI: 1.00–1.75), and negative emotional experiences (OR = 1.15, 95% CI: 1.03–1.29). Our study could provide the basis for risk assessment and preventive interventions for early onset breast cancer. PMID:27977584

    Whether or not breast-feeding is protective against asthma among children is still controversial. Therefore, we examined the effects of breast-feeding on hospitalization for asthma in early childhood. Secondary data analyses of a nationwide longitudinal survey of children in Japan ongoing since 2001, with results collected from 2001 to 2004. We used logistic regression models to evaluate the associations of breast-feeding with hospitalization for asthma in children between the ages of 6 and 42 months, adjusting for children's factors (sex, day-care attendance and presence of older siblings) and maternal factors (educational attainment and smoking habit). Setting All over Japan. Term singleton children with information on feeding practices during infancy (n 43367). After adjusting for maternal factors and children's factors, exclusive breast-feeding at 6-7 months of age was associated with decreased risk of hospitalization for asthma in children. The adjusted odds ratio was 0.77 (95% CI 0.56, 1.06). One-month longer duration of breast-feeding was associated with a 4% decreased risk of hospitalization for asthma (OR = 0.96; 95% CI 0.92, 0.99). The protective effects of breast-feeding on hospitalization for asthma were observed in children between the ages of 6 and 42 months.

    To test the hypothesis that duration of breast feeding is related to changes in vascular function relevant to the development of cardiovascular disease. Population based observational study. Cambridge. 331 adults (171 women, 160 men) aged between 20 and 28 years, born in Cambridge Maternity Hospital. Distensibility of brachial artery, type and duration of infant feeding, current lipid profile, and other cardiovascular risk factors. The longer the period of breast feeding the less distensible the artery wall in early adult life, with no sex differences (regression coefficient = -3.93 micrometer/month, 95% confidence interval -7.29 to -0.57, P=0.02). However, in those breast fed for less than four months, arterial distensibility was not significantly reduced compared with an exclusively formula fed group. The vascular changes observed were not explained by alterations in plasma cholesterol concentration in adult life. Breast feeding in infancy is related to reduced arterial function 20 years later. These data should not alter current recommendations in favour of breast feeding, which has several benefits for infant health. Further work is needed, however, to explore the optimal duration of breast feeding in relation to cardiovascular outcomes.

Longitudinal, genetic association study. Urban university cancer center. Three cohorts of postmenopausal women: 37 women with breast cancer receiving chemotherapy and anastrozole, 41 women with breast cancer receiving anastrozole alone, and 50 healthy women. Cognitive function was evaluated three times during a 12-month period using a comprehensive neuropsychological test battery.

Performance or changes in performance on tasks of executive function, attention, verbal learning and memory, and visual learning and memory were found to be influenced by APOE genotype and/or interactions between APOE genotype and study cohort. The results indicate that cognitive function in postmenopausal women with breast cancer is modified by APOE genotype and the combination of APOE genotype and treatment. APOE genotype, along with other biomarkers, may be used in the future to assist nurses in identifying women with breast cancer most at risk for cognitive decline.

    It is now recognised that the breast exhibits a circadian rhythm which reflects its physiology. There is increasing evidence that rhythms associated with malignant cells proliferation are largely non-circadian and that a circadian to ultradian shift may be a general correlation to neoplasia. Cancer development appears to generate its own thermal signatures and the complexity of these signatures may be a reflection of its degree of development. The limitations of mammography as a screening modality especially in young women with dense breasts necessitated the development of novel and more effective screening strategies with a high sensitivity and specificity. Dynamic thermal analysis of the breast is a safe, non invasive approach that seems to be sensitive for the early detection of breast cancer. This article focuses on dynamic thermal analysis as an evolving method in breast cancer detection in pre-menopausal women with dense breast tissue. Prospective multi-centre trials are required to validate this promising modality in screening. The issue of false positives require further investigation using molecular genetic markers of malignancy and novel techniques such as mammary ductoscopy. PMID:15819982

    Mammography-based screening has been a valuable imaging tool for the early detection of non-palpable lesions and has contributed to significant reduction in breast cancer associated mortality. However, the breast imaging community recognizes that mammography is not ideal, and in particular is inferior for women with dense breasts. Also, the 2-D projection of a 3-D organ results in tissue superposition contributing to false-positives. The sensitivity of mammography is breast-density dependent. Its sensitivity, especially in dense breasts, is low due to overlapping tissue and the fact that normal breast tissue, benign lesions and breast cancers all have similar "densities", making lesion detection more difficult. We ideally need 3-D imaging for imaging the 3-D breast. MRI is 3-D, whole breast ultrasound is 3-D, digital breast tomosynthesis is called 3-D but is really "pseudo 3-D" due to poor resolution along the depth-direction. Also, and importantly, we need to be able to administer intravenous contrast agents for optimal imaging, similar to other organ systems in the body. Dedicated breast CT allows for 3-D imaging of the uncompressed breast. In current designs, the patient is positioned prone on the table and the breast is pendant through an aperture and the scan takes approximately 10 seconds [O'Connell et al., AJR 195: 496-509, 2010]. Almost on the heels of the invention of CT itself, work began on the development of dedicated breast CT. These early breast CT systems were used in clinical trials and the results from comparative performance evaluation of breast CT and mammography for 1625 subjects were reported in 1980 [Chang et al., Cancer 46: 939-46, 1980]. However, the technological limitations at that time stymied clinical translation for decades. Subsequent to the landmark article in 2001 [Boone et al., Radiology 221: 657-67, 2001] that demonstrated the potential feasibility in terms of radiation dose, multiple research groups are actively investigating

    Purpose This study investigated the clinicopathological features of operable breast cancer lesions located in different hemispheres of the breast and determined related survival outcomes. Methods Data from 5,330 patients with invasive ductal carcinoma were retrospectively analyzed based on tumor location. Results The median follow-up time was 68 months (range, 18-176 months). Patients with breast cancer located in the outer hemisphere of the breast had lesions with more advanced nodal stages and more frequently received adjuvant chemotherapy than patients with breast cancer in the inner hemisphere. The 5-year disease-free survival (DFS) rates of patients with tumors located in outer versus inner hemispheres were 81.5% and 77.0%, respectively (p=0.004); the overall survival (OS) rates were 90.7% and 88.8%, respectively (p<0.001). The association between tumor location and the 5-year DFS rate was most apparent in node-positive patients (73.1% vs. 65.8% for outer vs. inner hemisphere lesions, p<0.001) and in patients with primary tumors greater than 2 cm in diameter (78.2% vs. 72.3%, p=0.002). Multivariate analysis showed that tumor location was an independent predictor of DFS (hazard ratio [HR], 1.23; p=0.002) and OS (HR, 1.28; p=0.006). There were no significant differences in 5-year DFS or OS rates between patients with outer versus inner hemisphere tumors when internal mammary node irradiation was performed. Conclusion This study demonstrated that tumor location was an independent prognostic factor for operable breast cancer. Internal mammary node irradiation is recommended for patients with breast cancer of the inner hemisphere and positive axillary lymph nodes or large primary tumors. PMID:25834609

    Background I-SPY2, a standing, multicenter, adaptive phase 2 neoadjuvant trial ongoing in high-risk clinical stage II/III breast cancer, is designed to evaluate multiple, novel experimental agents added to standard chemotherapy for their ability to improve the rate of pathologic complete response (pCR). Experimental therapies are compared against a common control arm. We report efficacy for the tyrosine kinase inhibitor neratinib. Methods Eligible women had ≥2.5 cm stage II/III breast cancer, categorized into 8 biomarker subtypes based on HER2, hormone-receptor status (HR), and MammaPrint. Neratinib was evaluated for 10 signatures (prospectively defined subtype combinations), with primary endpoint pCR. MR volume changes inform likelihood of pCR for each patient prior to surgery. Adaptive assignment to experimental arms within disease subtype was based on current Bayesian probabilities of superiority over control. Accrual to experimental arm stop at any time for futility or graduation within a particular signature based on Bayesian predictive probability of success in a confirmatory trial. The maximum sample size in any experimental arm is 120 patients, Results With 115 patients and 78 concurrently randomized controls, neratinib graduated in the HER2+/HR− signature, with mean pCR rate 56% (95% PI: 37 to 73%) vs 33% for controls (11 to 54%). Final predictive probability of success, updated when all pathology data were available, was 79%. Conclusion Adaptive, multi-armed trials can efficiently identify responding tumor subtypes. Neratinib added to standard therapy is highly likely to improve pCR rates in HER2+/HR2212; breast cancer. Confirmation in I-SPY 3, a phase 3 neoadjuvant registration trial, is planned. PMID:27406346

    Objective The study was performed in order to determine the behavior of college students studying in health related departments for the early diagnosis of breast cancer. Materials and Methods This study is a cross sectional study. 336 female students studying in School of Nursing and School of Health Sciences at a foundation university in Istanbul were included. A questionnaire directed to collect data regarding the participants’ socio-demographic characteristics and their behavior on the early diagnosis of breast cancer was used. Data were evaluated by descriptive statistics and chi-square test. Results The mean age of students was 21.26±1.94, and 30.7% of the participants majored in nutrition, 29.2% in nursing, 22.9% in midwifery, 17.3% in physical therapy and rehabilitation departments. It was determined that 53.3% of the students made regular breast self-examination (BSE), and 88.1% did not get a clinical breast examination (CBE) within the last year. It was noticed that students who had BSE training, made more BSE and CBE as compared to those who did not get any education. Students with family history of breast cancer was performing more BSE that those without a family history. It was identified that students with BSE training and family history of breast cancer used BSE at a higher rate. Conclusion It was identified that students with BSE training and family history of breast cancer usage of techniques to perform a BSE at a higher rate. PMID:28331661

    Current information on the incidence and prevalence of bone metastases in women with breast cancer is scarce. This study examined the occurrence and predictors of bone metastases, as well as post-metastasis survival in a prospective cohort of Canadian women with breast cancer. We included women treated for early-stage (stage I, II, or III) breast cancer at the Henrietta Banting Breast Centre (HBBC) in Toronto, Canada between 1987 and 2000. Data were abstracted from medical records and pathology reports in the HBBC database; follow-up extended to end of data availability or August 31, 2015. Actuarial survival analyses provided cumulative incidence of bone metastases at 5, 10, and 15 years after breast cancer diagnosis. Kaplan-Meier curves describe breast cancer mortality. Regression models assessed patient, tumor, and treatment characteristics as predictors of bone metastases with all-cause mortality as a competing risk. Among 2097 women studied, the 5-, 10-, and 15-year probability of bone metastasis was 6.5, 10.3, and 11.3 % for the first recurrence, and 8.4, 12.5, and 13.6 % for any bone recurrence. At median follow-up (12.5 years), 13.2 % of patients had bone metastases. Median survival was 1.6 years following bone metastasis, and shorter if both bone and visceral metastases occurred. Advanced age and adjuvant treatment with tamoxifen were protective against bone metastasis. In this representative cohort of women diagnosed with early-stage breast cancer in Ontario, Canada, with long follow-up, the incidence of bone metastases was consistent with longitudinal studies from the United Kingdom, Denmark, and the US.

    Cancer.gov

    Breast-conserving lumpectomy followed by radiation therapy has been shown to be an alternative strategy, competitive to mastectomy, in preventing mortality caused by breast cancer. However, besides negative short-term effects (blood flow disturbances, painful erythema, etc.) breast irradiation causes severe long-term side-effects (leucopenia, anemia, breast edema, fibrosis, increase of angiosarcoma, leukemia, myelodysplastic syndromes). Therefore, the identification of individual susceptibility to radiation and improved patient-specific radiotherapy planning are highly desirable for personalised treatment in breast cancer. Why early and predictive diagnosis is crucial for long-term outcomes of breast cancer? Breast cancer is the most common cause of cancer death among women with an average incidence rate of 10-12 per 100 women. In 2005, breast cancer led to 502,000 deaths worldwide. Advanced stages of breast cancer lead to the development of metastasis predominantly in the lymph nodes, bone, lung, skin, brain, and liver. Although breast-MRI is currently the most sensitive diagnostic tool for breast imaging, its specificity is limited resulting in a negative impact for surgical management in approximately 9 % of cases. Early diagnosis has been demonstrated to be highly beneficial, enabling significantly enhanced therapy efficiency and possibly full recovery.

    The heterogeneity of breast cancer makes identifying effective therapies challenging. The I-SPY 2 trial, a multicenter, adaptive phase 2 trial of neoadjuvant therapy for high-risk clinical stage II or III breast cancer, evaluated multiple new agents added to standard chemotherapy to assess the effects on rates of pathological complete response (i.e., absence of residual cancer in the breast or lymph nodes at the time of surgery). We used adaptive randomization to compare standard neoadjuvant chemotherapy plus the tyrosine kinase inhibitor neratinib with control. Eligible women were categorized according to eight biomarker subtypes on the basis of human epidermal growth factor receptor 2 (HER2) status, hormone-receptor status, and risk according to a 70-gene profile. Neratinib was evaluated against control with regard to 10 biomarker signatures (prospectively defined combinations of subtypes). The primary end point was pathological complete response. Volume changes on serial magnetic resonance imaging were used to assess the likelihood of such a response in each patient. Adaptive assignment to experimental groups within each disease subtype was based on Bayesian probabilities of the superiority of the treatment over control. Enrollment in the experimental group was stopped when the 85% Bayesian predictive probability of success in a confirmatory phase 3 trial of neoadjuvant therapy reached a prespecified threshold for any biomarker signature ("graduation"). Enrollment was stopped for futility if the probability fell to below 10% for every biomarker signature. Neratinib reached the prespecified efficacy threshold with regard to the HER2-positive, hormone-receptor-negative signature. Among patients with HER2-positive, hormone-receptor-negative cancer, the mean estimated rate of pathological complete response was 56% (95% Bayesian probability interval [PI], 37 to 73%) among 115 patients in the neratinib group, as compared with 33% among 78 controls (95% PI, 11 to 54

    Thyroid storm is a rare disease, occurring in less than 1% of all thyrotoxicoses. Diagnosis and therapy still have serious problems. We review 14 patients who were operated on between 1992 and 1999 because of thyroid storm. All of the ten women and four men, aged 27 to 77 years, had an underlying thyroid disease. Autonomies were found in seven, Grave's disease in four, and a nodular goiter in three patients. The precipitating events were in five patients an antiarrhythmic therapy with amiodarone, on three occasions application of contrast medium, two times omission of antithyroid drugs and in one patient severe hyperglycemia with acidosis. In three patients no triggering factor was discovered. All patients were treated with high-dose antithyroid therapy. On admission, four patients were graded as stage-one thyroid crisis, three patients had stage-two and seven patients stage-three disease. All patients were operated on within 18 h of admission. Surgical procedure was in seven cases a bilateral subtotal resection, four times thyroidectomy, and in three patients a Dunhill procedure. After the operation, 12 patients improved rapidly. Two 77 and 74-year-old women died 1 or 2 days after the operation, respectively, one from heart failure and the other from multiple organ failure. Both had been diagnosed as thyrotoxic crisis stage three. Early operation should be adopted as a standard option in thyroid storm that cannot be controlled medically. Best results are achieved if the operation is done at stage one or two of the disease.

    The 15th St. Gallen International Breast Cancer Conference 2017 in Vienna, Austria reviewed substantial new evidence on loco-regional and systemic therapies for early breast cancer. Treatments were assessed in light of their intensity, duration and side-effects, seeking where appropriate to escalate or de-escalate therapies based on likely benefits as predicted by tumor stage and tumor biology. The Panel favored several interventions that may reduce surgical morbidity, including acceptance of 2 mm margins for DCIS, the resection of residual cancer (but not baseline extent of cancer) in women undergoing neoadjuvant therapy, acceptance of sentinel node biopsy following neoadjuvant treatment of many patients, and the preference for neoadjuvant therapy in HER2 positive and triple-negative, stage II and III breast cancer. The Panel favored escalating radiation therapy with regional nodal irradiation in high-risk patients, while encouraging omission of boost in low-risk patients. The Panel endorsed gene expression signatures that permit avoidance of chemotherapy in many patients with ER positive breast cancer. For women with higher risk tumors, the Panel escalated recommendations for adjuvant endocrine treatment to include ovarian suppression in premenopausal women, and extended therapy for postmenopausal women. However, low-risk patients can avoid these treatments. Finally, the Panel recommended bisphosphonate use in postmenopausal women to prevent breast cancer recurrence. The Panel recognized that recommendations are not intended for all patients, but rather to address the clinical needs of the majority of common presentations. Individualization of adjuvant therapy means adjusting to the tumor characteristics, patient comorbidities and preferences, and managing constraints of treatment cost and access that may affect care in both the developed and developing world. © The Author 2017.

    breast-feeding outcomes are often worse after caesarean section compared to vaginal childbirth. this study characterises mothers' breast-feeding intentions and their infant feeding experiences after caesarean childbirth. data are from 115 mothers on a postnatal unit in Northeast England during February 2006-March 2009. Interviews were conducted an average of 1.5 days (range 1-6 days) after the women underwent unscheduled or scheduled caesarean. thematic analysis of the data suggested was mostly considered the 'right thing to do,' preferable, natural, and 'supposedly healthier,' but tiring and painful. Advantages of supplementation involved more satiated infants, feeding ease, and longer sleep bouts. The need for 'thinking about yourself' was part of caesarean recovery. Infrequent feeding was concerning but also enabled maternal rest. Other breast-feeding obstacles were maternal mobility limitations, positioning difficulties, and frustration at the need for assistance. Participants were confused about nocturnal infant wakings, leading many to determine that they had insufficient milk. Mothers were surprised that sub-clinically poor infant condition was common following caesarean section. Some breast-feeding difficulty stemmed from 'mucus' expulsion that had to occur before the infants could be 'interested' in feeding. Women who cited motivations for breast feeding that included benefit to themselves were more likely to exclusively breast feed on the postnatal unit after their caesareans than those who reported infant-only motivations. for the majority of mothers, breast feeding after a caesarean is affected by interrelated and compounding difficulties. Provision of more relational breast-feeding information may enable families to better anticipate early feeding experiences after caesarean section childbirth. © 2013 Elsevier Ltd.

  17. Role of Ovarian Function Suppression in Premenopausal Women with Early Breast Cancer

    PubMed Central

    2016-01-01

    Historically, endocrine therapy for breast cancer began with ovarian ablation (OA) for the treatment of premenopausal patients. After the identification of estrogen receptors and the development of many antiestrogens, tamoxifen has been approved and used as the standard endocrine therapy for hormonal receptor (HR)-positive premenopausal patients to date. With the development of luteinizing hormone-releasing hormone agonists, the paradigm of endocrine therapy for premenopausal women with HR-positive breast cancer began to change from OA to ovarian function suppression (OFS). To date, the indication for OFS was limited to those premenopausal patients with HR-positive breast cancer who were unable to use tamoxifen as the primary adjuvant endocrine therapy. However, following the definitive demonstration of the therapeutic role of OFS added to tamoxifen or aromatase inhibitor after chemotherapy in large randomized trials, such as Tamoxifen and Exemestane Trial or Suppression of Ovarian Function Trial, the American Society of Clinical Oncology guidelines for the use of endocrine therapy in premenopausal HR-positive breast cancer were recently updated to recommend OFS in high-risk patients who required adjuvant chemotherapy. In contrast, the role of OFS to protect ovarian function during chemotherapy in premenopausal women has remained controversial, and some evidence showing the protective effect of OFS on the ovaries during chemotherapy as well as its therapeutic effect for breast cancer in premenopausal women with HR-negative breast cancer was recently published. Further evaluation is necessary to determine its exact role. In conclusion, the role of OA or OFS has been evolving, not only to improve the efficacy of breast cancer treatment, but also to preserve ovary function. OFS remains a main strategy for premenopausal women with HR-positive early breast cancer, though its exact role should be determined in further studies. PMID:28053622

    Purpose There is growing evidence that body size in early life influences lifetime breast cancer risk, but little is known for African American (AA) women. Methods We evaluated body size during childhood and young adulthood and breast cancer risk among 1,751 cases [979 AA and 772 European American (EA)] and 1,673 controls (958 AA and 715 EA) in the Women’s Circle of Health Study. Odds ratio (OR) and 95% confidence intervals (CI) were computed using logistic regression models while adjusting for potential covariates. Results Among AA women, being shorter at 7–8 y compared to peers was associated with increased postmenopausal breast cancer risk (OR: 1.68, 95% CI: 1.02–2.74), and being heavier at menarche with decreased postmenopausal breast cancer risk, although of borderline significance (OR: 0.45, 95% CI: 0.20–1.02). For EA women, being shorter from childhood through adolescence, particularly at menarche, was associated with reduced premenopausal breast cancer risk (OR: 0.55, 95% CI: 0.31–0.98). After excluding hormone replacement therapy users, an inverse association with postmenopausal breast cancer was found among EA women reporting to be heavier than their peers at menarche (OR: 0.18, 95% CI: 0.04–0.79). The inverse relationship between BMI at age 20 and breast cancer risk was stronger and only statistically significant in EA women. No clear association with weight gain since age 20 was found. Conclusions Findings suggest that the impact of childhood height on breast cancer risk may differ for EA and AA women and confirm the inverse association previously reported in EA populations with adolescent body fatness, in AA women.

  19. Early Breast Cancer Diagnosis Using Microwave Imaging via Space-Frequency Algorithm

    NASA Astrophysics Data System (ADS)

    Vemulapalli, Spandana

    The conventional breast cancer detection methods have limitations ranging from ionizing radiations, low specificity to high cost. These limitations make way for a suitable alternative called Microwave Imaging, as a screening technique in the detection of breast cancer. The discernible differences between the benign, malignant and healthy breast tissues and the ability to overcome the harmful effects of ionizing radiations make microwave imaging, a feasible breast cancer detection technique. Earlier studies have shown the variation of electrical properties of healthy and malignant tissues as a function of frequency and hence stimulates high bandwidth requirement. A Ultrawideband, Wideband and Narrowband arrays have been designed, simulated and optimized for high (44%), medium (33%) and low (7%) bandwidths respectively, using the EM (electromagnetic software) called FEKO. These arrays are then used to illuminate the breast model (phantom) and the received backscattered signals are obtained in the near field for each case. The Microwave Imaging via Space-Time (MIST) beamforming algorithm in the frequency domain, is next applied to these near field backscattered monostatic frequency response signals for the image reconstruction of the breast model. The main purpose of this investigation is to access the impact of bandwidth and implement a novel imaging technique for use in the early detection of breast cancer. Earlier studies show the implementation of the MIST imaging algorithm on the time domain signals via a frequency domain beamformer. The performance evaluation of the imaging algorithm on the frequency response signals has been carried out in the frequency domain. The energy profile of the breast in the spatial domain is created via the frequency domain Parseval's theorem. The beamformer weights calculated using these the MIST algorithm (not including the effect of the skin) has been calculated for Ultrawideband, Wideband and Narrowband arrays, respectively

  20. Microwave power imaging for ultra-wide band early breast cancer detection

    NASA Astrophysics Data System (ADS)

    Shao, Wenyi

    Due to the critical need for complementary or/and alternative modalities to current X-ray mammography for early-stage breast cancer detection, a 3D active microwave imaging system has been developed. This thesis presents a detailed method for rapid, high contrast microwave imaging for the purpose of breast survey. In the proposed imaging system, several transmitters polarized in different directions take turns sending out a low-power UWB pulse into the breast; backscattered signals are recorded by a synthetic aperture antenna array. These backscattered signals are passed through a beamformer, which spatially focuses the waveforms to image backscattered energy as a function of location in the breast. A simple Delay-and-Sum algorithm is applied to test the proposed multistatic multi-polarized detection scheme. The obtained 2-D and 3-D numerical results have demonstrated the feasibility and superiority of detecting small malignant breast tumors using our antenna strategy. An improved algorithm of microwave power imaging for detecting small breast tumors within an MRI-derived phantom is also introduced. Our imaging results demonstrate that a high-quality image can be reached without solving the inverse problem. To set up an experimental system for future clinical investigation, we developed two Vivaldi antennas, which have a notable broad band property, good radiation pattern, and a suitable size for breast cancer detection. Finally, an antenna array which consists of eight proposed Vivaldi antennas is introduced. By conveniently moving up/down and rotating this antenna array, it can be used for the multistatic breast cancer imaging and qualified for our multi-polarized scan mode.

    Recent studies suggest trends toward more mastectomies for primary breast cancer treatment. We assessed survival after mastectomy and breast-conserving surgery (BCS) with radiation for early-stage breast cancer among non-selected populations of women and among women similar to those in clinical trials. Using population-based data from Surveillance Epidemiology, and End Results cancer registries linked with Medicare administrative data from 1992 to 2005, we conducted propensity score analysis of survival following primary therapy for early-stage breast cancer, including BCS with radiation, BCS without radiation, mastectomy with radiation, and mastectomy without radiation. Adjusted survival was greatest among women who had BCS with radiation (median survival = 10.98 years). Compared with this group, mortality was higher among women who had mastectomy without radiation (median survival 10.04 years, adjusted hazard ratio (HR) = 1.19, 95% confidence interval (CI) = 1.14-1.23), mastectomy with radiation (median survival 10.02 years, HR = 1.20, 95% CI = 1.14-1.27), and BCS without radiation (median survival 7.63 years, HR = 1.81, 95% CI = 1.70-1.92). Among women representative of those eligible for clinical trials (age ≤70 years, Charlson comorbidity score = 0/1, and stage 1 tumors), there were no differences in survival for women who underwent BCS with radiation or mastectomy. In conclusion, after careful adjustment for differences in patient, physician, and hospital characteristics, we found better survival for BCS with radiation versus mastectomy among older early-stage breast cancer patients, with no difference in survival for BCS with radiation versus mastectomy among women representative of those in clinical trials. These findings are reassuring in light of recent trends towards more aggressive primary breast cancer therapy.

    Although human milk is generally accepted as the gold standard for the feeding of term infants, its use in the preterm and very low birth weight (VLBW) infants particularly in the initial period of birth has been more controversial. Little is known about the risks and benefits of early introduction of breast feeding on preterm VLBW infants. The primary object of this study was to evaluate the safety and benefit of early breast milk feeding in preterm VLBW newborns during their initial hospitalization periods. Therefore a prospective observational study was conducted among 37 preterm VLBW infants who were admitted to the Neonatal ward of Sir Salimullah Medical College and Mitford Hospital during the period of February 15th to July 25th, 2003. Oral feeding with breast milk was started within one hour of birth, and weight gain, feeding tolerance, nosocomial infection rate as well as other associated problems of pre-maturity, and postnatal growth curve were recorded upto 16th postnatal day. Seventy three percent of the newborns tolerate breast milk well from the very beginning, and the rest did not tolerate initially but all of them tolerate within 24 hours of birth. Infants had less initial weight loss (20 ± 10 gm) and faster recovery of birth weight. They regained their birth weight at 12th postnatal day. Hyper-bilirubinaemia was found in only 22% cases, and was observed in the group who initially didn't tolerate breast milk and was on intravenous fluid. Nobody developed symptomatic hypoglycemia or necrotizing enterocolitis (NEC). Two cases of sepsis and another two cases of minor infection like conjunctivitis and oral thrush have occurred. In conclusion it can be said that early breast milk feeding is safe in preterm VLBW infants and it helps to promote growth and reduce the need for intravenous line.

    At present, the majority of patients with breast cancer are diagnosed at early stages of disease development. However, a considerable number of such cases develop secondary malignancies after a relatively short period of time. The presence of circulating tumor cells (CTCs) has been proposed as a strong biomarker to predict disease recurrence in metastatic breast cancer. However, the prognostic significance is not clear in early breast cancer. We present results on CTC determination in peripheral blood in non-metastatic breast cancer patients in the context of neoadjuvant treatment. Twenty-six breast cancer patients, scheduled for neoadjuvant therapy, were enrolled in a prospective study, of which 24 were able to complete therapy. CTC assessment was performed by sorting out cytokeratin-positive cells from 10 ml of peripheral blood using immunomagnetic separation, followed by immunocytochemical characterization of cells. Seventeen blood samples out of 24 patients were CTC-positive when collected prior to neoadjuvant chemotherapy. No significant correlations were found between the presence of CTCs and lymph node status (p=0.1), histological type (p=0.802), stage (p=0.43) or overall survival (OS) (p=0.599). Thirteen CTC-positive samples were observed in blood samples collected after treatment. Univariate analyses revealed that the presence of CTCs was related to OS when the detection was positive both before and after treatment (p=0.023). CTCs can be a strong prognostic marker in early breast cancer. The persistence of CTCs before and after treatment can identify a subpopulation of patients with an increased risk of recurrence.

    Mammography is the best tool for early detection of Breast Cancer. In this diagnostic radiology modality it is necessary to establish the criteria to ensure the proper use and operation of the equipment used to obtain mammographic images in order to contribute to the safe use of ionizing radiation. The aim of the work was to implement at FUCAM-AC the radiation protection program which must be established for patients and radiation workers according to Mexican standards [1-4]. To achieve this goal, radiation protection and quality control manuals were elaborated [5]. Furthermore, a quality control program (QCP) in the mammography systems (analog/digital), darkroom included, has been implemented. Daily sensitometry, non-variability of the image quality, visualizing artifacts, revision of the equipment mechanical stability, compression force and analysis of repetition studies are some of the QCP routine tests that must be performed by radiological technicians of this institution as a set of actions to ensure the protection of patients. Image quality and patients dose assessment were performed on 4 analog equipment installed in 2 mobile units. In relation to dose assessment, all equipment passed the acceptance criteria (<3 mGy per projection). The image quality test showed that most images (70%)- presented artifacts. A brief summary of the results of quality control tests applied to the equipment and film processor are presented. To maintain an adequate level of quality and safety at FUCAM-AC is necessary that the proposed radiation protection program in this work is applied.

    Background The aim of this study was to investigate the incidence and prognostic value of disseminated tumor cells in bone marrow of breast carcinoma patients with early disease, and to analyze this finding in relation to lymph node involvement, determined by sentinel lymph node (SLN) biopsy analysis, and to prognostic factors of interest. Methods 104 patients with operable (T < 3 cm) breast cancer and clinically- and sonographically-negative axillary lymph nodes were scheduled for SLN biopsy. Bone marrow aspirates were collected before the start of surgery from both iliac crests, and mononuclear cell layers were separated by density centrifugation (Lymphoprep). Slide preparations were then examined for the presence of disseminated tumor cells by immunocytochemistry with anti-cytokeratin antibodies (A45-B/B3). Lymphoscintigraphy was performed 2 hours after intratumor administration of 2 mCi (74 MBq) of 99mTc colloidal albumin. The SLN was evaluated for the presence of tumor cells by hematoxylin-eosin staining and, when negative, by immunocytochemistry using anti-cytokeratin antibody (CAM 5.2). Survival analyses and comparative analyses were performed on the results of bone marrow determinations, SLN biopsy, and known prognostic factors, including breast cancer subtypes according to the simplified classification based on ER, PR and HER2. Results Lymph node and hematogenous dissemination occur in one-third of patients with early-stage breast cancer, although not necessarily simultaneously. In our study, disseminated tumor cells were identified in 22% of bone marrow aspirates, whereas 28% of patients had axillary lymph node involvement. Simultaneous lymph node and bone marrow involvement was found in only 5 patients (nonsignificant). In the survival study (60 months), a higher, although nonsignificant rate of disease-related events (13%) was seen in patients with disseminated tumor cells in bone marrow, and a significant association of events was documented with the

    Our aim was to analyze the impact of a concurrent autoimmune disease on outcome of patients with early breast cancer. We reviewed medical charts of patients with a diagnosis of autoimmune diseases (AD) among a population of 17.153 cases. We categorized ADs as endocrine, rheumatic, systemic, neurological diseases and vasculitis. For each patient in the study group, we matched 2 patients. The events to determine overall survival (OS) and disease free survival (DFS) were identified from follow-up data. We identified 279 (1.62%) patients with early breast cancer and concurrent ADs. The median follow-up was 7.0 years. The 10-year OS rate was 86% (95% CI, 80% to 91%) in the study group and 90% (95% CI, 86% to 93%) for the control group (p = 0.011). In patients with ER positive/HER2 negative subtype a worse OS was observed in the study group when compared to the control group (p = 0.0046); this difference remained statistically significant when the analysis was restricted to breast cancer mortality (p = 0.045). The 10-year DFS rate was 69% (95% CI, 61% to 76%) in the study group and 72% (95% CI, 66% to 77%) for the control group (p = 0.22). Autoimmunity at diagnosis of early breast cancer is associated with worse survival. PMID:27323400

    To use the critical social theory as a framework to analyze the oppression of Jordanian women with early stage breast cancer in the decision-making process for surgical treatment and suggest strategies to emancipate these women to make free choices. This is a discussion paper utilizing the critical social theory as a framework for analysis. The sexist and paternalistic ideology that characterizes Jordanian society in general and the medical establishment in particular as well as the biomedical ideology are some of the responsible ideologies for the fact that many Jordanian women with early stage breast cancer are denied the right to choose a surgical treatment according to their own preferences and values. The financial and political power of Jordanian medical organizations (e.g., Jordan Medical Council), the weakness of nursing administration in the healthcare system, and the hierarchical organization of Jordanian society, where men are first and women are second, support these oppressing ideologies. Knowledge is a strong tool of power. Jordanian nurses could empower women with early stage breast cancer by enhancing their knowledge regarding their health and the options available for surgical treatment. To successfully emancipate patients, education alone may not be enough; there is also a need for health care providers' support and unconditional acceptance of choice. To achieve the aim of emancipating women with breast cancer from the oppression inherent in the persistence of mastectomy, Jordanian nurses need to recognize that they should first gain greater power and authority in the healthcare system.

  10. Tailoring Chemotherapy in Early-Stage Breast Cancer: Based on Tumor Biology or Tumor Burden?

    The question of whether to offer adjuvant chemotherapy to patients with early-stage breast cancer has always been challenging to answer. It is well known that a substantial proportion of patients with early-stage breast cancer are over treated, especially when staging and hormonal and HER2 receptors are solely taken into consideration. The advances in our knowledge of breast cancer biology and its clinical implications were the basis for the discovery of additional reliable prognostic markers to aid decision making for adjuvant treatment. Gene expression profiling is a molecular tool that more precisely defines the intrinsic characteristics of each individual tumor. The application of this technology has led to the development of gene signatures/profiles with relevant prognostic-and some predictive-value that have become important tools in defining which patients with early-stage breast cancer can be safely spared from chemotherapy. However, the exact clinical utility of these tools will only be determined after the results of two large prospective randomized trials, MINDACT and TailorX, evaluating their role become available. Notwithstanding the existence of these genomic tools, tumor burden (defined as tumor size and nodal status) still has independent prognostic value and must be incorporated in decision making. In addition, these gene signatures have limited predictive value, and new biomarkers and new targets are needed. Therefore close collaboration between clinicians and scientists is crucial. Lastly, issues of cost-effectiveness, reimbursement, and availability are crucial and widely variable around the globe.

    The identification of early-stage breast cancer patients at high risk of relapse would allow tailoring of adjuvant therapy approaches. We assessed whether analysis of circulating tumor DNA (ctDNA) in plasma can be used to monitor for minimal residual disease (MRD) in breast cancer. In a prospective cohort of 55 early breast cancer patients receiving neoadjuvant chemotherapy, detection of ctDNA in plasma after completion of apparently curative treatment-either at a single postsurgical time point or with serial follow-up plasma samples-predicted metastatic relapse with high accuracy [hazard ratio, 25.1 (confidence interval, 4.08 to 130.5; log-rank P < 0.0001) or 12.0 (confidence interval, 3.36 to 43.07; log-rank P < 0.0001), respectively]. Mutation tracking in serial samples increased sensitivity for the prediction of relapse, with a median lead time of 7.9 months over clinical relapse. We further demonstrated that targeted capture sequencing analysis of ctDNA could define the genetic events of MRD, and that MRD sequencing predicted the genetic events of the subsequent metastatic relapse more accurately than sequencing of the primary cancer. Mutation tracking can therefore identify early breast cancer patients at high risk of relapse. Subsequent adjuvant therapeutic interventions could be tailored to the genetic events present in the MRD, a therapeutic approach that could in part combat the challenge posed by intratumor genetic heterogeneity.

    While breast cancer outcomes are improving steadily in younger women due to advances in screening and improved therapies, there has been little change in outcomes among the older age group. It is inevitable that comorbidities/frailty rates are higher, which may increase the risks of some breast cancer treatments such as surgery and chemotherapy, many older women are healthy and may benefit from their use. Adjusting treatment regimens appropriately for age/comorbidity/frailty is variable and largely non-evidence based, specifically with regard to rates of surgery for operable oestrogen receptor-positive disease and rates of chemotherapy for high-risk disease. This multicentre, parallel group, pragmatic cluster randomised controlled trial (RCT) (2015-18) reported here is nested within a larger ongoing 'Age Gap Cohort Study' (2012-18RP-PG-1209-10071), aims to evaluate the effectiveness of a complex intervention of decision support interventions to assist in the treatment decision making for early breast cancer in older women. The interventions include two patient decision aids (primary endocrine therapy vs surgery/antioestrogen therapy and chemotherapy vs no chemotherapy) and a clinical treatment outcomes algorithm for clinicians. National and local ethics committee approval was obtained for all UK participating sites.

    Imaging in the evaluation and follow-up of patients with early or advanced breast cancer is an important aspect of cancer care. The role of imaging in breast cancer depends on the goal and should only be performed to guide clinical decisions. Imaging is valuable if a finding will change the course of treatment and improve outcomes, whether this is disease-free survival, overall survival or quality-of-life. In the last decade, imaging is often overused in oncology and contributes to rising healthcare costs. In this context, we review the data that supports the appropriate use of imaging for breast cancer patients. We will discuss: 1) the optimal use of staging imaging in both early (Stage 0-II) and locally advanced (Stage III) breast cancer, 2) the role of surveillance imaging to detect recurrent disease in Stage 0-III breast cancer and 3) how patients with metastatic breast cancer should be followed with advanced imaging.

    Operational early warning platform for extreme meteorological events Most natural disasters are related to extreme weather events (e.g. typhoons); weather conditions, however, are also highly relevant for humanitarian and disaster relief operations during and after other natural disaster like earthquakes. The internet service "Wettergefahren-Frühwarnung" (WF) provides various information on extreme weather events, especially when these events are associated with a high potential for large damage. The main focus of the platform is on Central Europe, but major events are also monitored worldwide on a daily routine. WF provides high-resolution forecast maps for many weather parameters which allow detailed and reliable predictions about weather conditions during the next days in the affected areas. The WF service became operational in February 2004 and is part of the Center for Disaster Management and Risk Reduction Technology (CEDIM) since 2007. At the end of 2011, CEDIM embarked a new type of interdisciplinary disaster research termed as forensic disaster analysis (FDA) in near real time. In case of an imminent extreme weather event WF plays an important role in CEDIM's FDA group. It provides early and precise information which are always available and updated several times during a day and gives advice and assists with articles and reports on extreme events.

    To establish a preoperative decision model for accurate indication of systemic therapy in early-stage breast cancer using multiparametric MRI at 7-tesla field strength. Patients eligible for breast-conserving therapy were consecutively included. Patients underwent conventional diagnostic workup and one preoperative multiparametric 7-tesla breast MRI. The postoperative (gold standard) indication for systemic therapy was established from resected tumor and lymph-node tissue, based on 10-year risk-estimates of breast cancer mortality and relapse using Adjuvant! Online. Preoperative indication was estimated using similar guidelines, but from conventional diagnostic workup. Agreement was established between preoperative and postoperative indication, and MRI-characteristics used to improve agreement. MRI-characteristics included phospomonoester/phosphodiester (PME/PDE) ratio on 31-phosphorus spectroscopy (31P-MRS), apparent diffusion coefficients on diffusion-weighted imaging, and tumor size on dynamic contrast-enhanced (DCE)-MRI. A decision model was built to estimate the postoperative indication from preoperatively available data. We included 46 women (age: 43-74yrs) with 48 invasive carcinomas. Postoperatively, 20 patients (43%) had positive, and 26 patients (57%) negative indication for systemic therapy. Using conventional workup, positive preoperative indication agreed excellently with positive postoperative indication (N = 8/8; 100%). Negative preoperative indication was correct in only 26/38 (68%) patients. However, 31P-MRS score (p = 0.030) and tumor size (p = 0.002) were associated with the postoperative indication. The decision model shows that negative indication is correct in 21/22 (96%) patients when exempting tumors larger than 2.0cm on DCE-MRI or with PME>PDE ratios at 31P-MRS. Preoperatively, positive indication for systemic therapy is highly accurate. Negative indication is highly accurate (96%) for tumors sized ≤2,0cm on DCE-MRI and with PME

    Photonic crystal surfaces offer a compelling platform for improving the sensitivity of surface-based fluorescent assays used in disease diagnostics. Through the complementary processes of photonic crystal enhanced excitation and enhanced extraction, a periodic dielectric-based nanostructured surface can simultaneously increase the electric field intensity experienced by surface-bound fluorophores and increase the collection efficiency of emitted fluorescent photons. Through the ability to inexpensively fabricate photonic crystal surfaces over substantial surface areas, they are amenable to single-use applications in biological sensing, such as disease biomarker detection in serum. In this review, we will describe the motivation for implementing high-sensitivity, multiplexed biomarker detection in the context of breast cancer diagnosis. We will summarize recent efforts to improve the detection limits of such assays though the use of photonic crystal surfaces. Reduction of detection limits is driven by low autofluorescent substrates for photonic crystal fabrication, and detection instruments that take advantage of their unique features.

    CA15.3 (also known as MUCI) is the most widely used marker in breast cancer. The aim of the present work was the evaluation of the prognostic value of preoperative serum CA15.3 levels in patients with primary breast cancer. This study included 818 women with a histologically verified diagnosis of invasive breast cancer. The serum values of CA15.3 were investigated at the time of primary diagnosis by means of an immunoradiometric assay based on the "sandwich" principle. The median follow-up period of patients free of recurrence was 38 months. Pre-operative CA15.3 serum levels ranged from 6 to 452 U/ml. Elevated CA15.3 levels (>30 U/ml) were found in 15.2% of patients. Statistical analysis showed that pre-operative CA15.3 serum levels were significantly higher in patients with large size tumors (T3 or T4) (p = 0.0001), as well as in those with node-positive tumors (p = 0.0001). In the univariate analysis, high CA15.3 levels were significantly associated with a lower probability of both relapse-free and overall survival in the overall group of patients (p = 0.0001 and p = 0.004, respectively) and in the subgroup with node-positive breast cancer (p = 0.001 and p = 0.03, respectively). In addition, multivariate analysis demonstrated that pre-operative levels of the antigen were significantly and independently associated with relapse-free survival in the overall group of patients, as well as in the subgroup of patients with node-positive breast cancer (p = 0.02 and p = 0.01, respectively). These results show that high pre-operative CA15.3 levels correlate with large size tumors and the presence of lymph node metastases and suggest that this antigen could be used as an additional prognostic marker.

    The results of the treatment of 176 patients with early breast cancer, using radiation therapy without mastectomy are reported. The likelihood of local recurrence was 5% for Stage I patients and 7% for Stage II patients. Local control was significantly greater in those patients receiving an iridium implant. The cumulative survival probability at five years is 96% for Stage I and 68% for Stage II. Gross tumor resection with careful reapproximation of the breast tissue and well-placed incisions facilitates the radiation therapy. Homogeneous external beam radiation to the breast and draining lymph nodes (4500 to 5000 rads) and supplemental local radiation to the sites of the primary lesion (in this series using interstitial implantation) are recommended. The frequency of normal tissue complications was low.

    Despite multiple randomized trials showing the efficacy of hypofractionated radiation therapy in early-stage breast cancer, the United States has been slow to adopt this treatment. The goal of this study was to evaluate the impact of individual radiation oncologists on the early adoption of hypofractionated radiation therapy for early-stage breast cancer. We identified 22,233 Medicare beneficiaries with localized breast cancer that was diagnosed from 2004 to 2011 who underwent breast-conserving surgery with adjuvant radiation. Multilevel, multivariable logistic models clustered by radiation oncologist and geographic practice area were used to determine the impact of the provider and geographic region on the likelihood of receiving hypofractionated compared with standard fractionated radiation therapy while controlling for a patient's clinical and demographic covariates. Odds ratios (OR) describe the impact of demographic or clinical covariates, and the median OR (MOR) describes the relative impact of the individual radiation oncologist and geographic region on the likelihood of undergoing hypofractionated radiation therapy. Among the entire cohort, 2333 women (10.4%) were treated with hypofractionated radiation therapy, with unadjusted rates ranging from 0.0% in the bottom quintile of radiation oncologists to 30.4% in the top quintile. Multivariable analysis found that the individual radiation oncologist (MOR 3.08) had a greater impact on the use of hypofractionation than did geographic region (MOR 2.10) or clinical and demographic variables. The impact of the provider increased from the year 2004 to 2005 (MOR 2.82) to the year 2010 to 2011 (MOR 3.16) despite the publication of long-term randomized trial results in early 2010. Male physician and radiation oncologists treating the highest volume of breast cancer patients were less likely to perform hypofractionation (P<.05). The individual radiation oncologist strongly influenced the likelihood of a patient

    BACKGROUND Data are needed on how life expectancy affects treatment decisions among women ≥80 years with early stage breast cancer. METHODS We used the linked Surveillance Epidemiology and End Results-Medicare claims dataset from 1992–2005 to identify women aged ≥80 newly diagnosed with lymph node negative, estrogen receptor positive tumors, ≤5 centimeters. To estimate life expectancy, we matched these women to women of similar age, region, and insurance, not diagnosed with breast cancer. We examined 5-year mortality of matched controls by illness burden (measured with the Charlson Comorbidity Index [CCI]) using Kaplan-Meier statistics. We examined treatments received by estimated life expectancy within CCI levels. We further examined factors associated with receipt of radiotherapy after breast conserving surgery (BCS). RESULTS Of 9,932 women, 39.6% underwent mastectomy, 30.4% received BCS plus radiotherapy, and 30.0% received BCS alone. Estimated 5-year mortality was 72% for women with CCIs of 3+, yet 38.0% of these women underwent mastectomy and 22.9% received radiotherapy after BCS. Conversely, estimated 5-year mortality was 36% for women with CCIs of 0 and 26.6% received BCS alone. Age 80–84, urban residence, higher grade, recent diagnosis, mammography use, and low comorbidity, were factors associated with receiving radiotherapy after BCS. Among women with CCIs of 3+ treated with BCS, 36.9% underwent radiotherapy. CONCLUSIONS Many women aged ≥80 with limited life expectancies receive radiotherapy after BCS for treatment of early stage breast cancers while many in excellent health do not. More consideration needs to be given to patient life expectancy when considering breast cancer treatments. KEY WORDS: Breast cancer, older women, treatment, life expectancy, radiation PMID:22368726

    For most older women with early breast cancer, standard treatment after breast-conserving surgery is adjuvant whole-breast radiotherapy and adjuvant endocrine treatment. We aimed to assess the effect omission of whole-breast radiotherapy would have on local control in older women at low risk of local recurrence at 5 years. Between April 16, 2003, and Dec 22, 2009, 1326 women aged 65 years or older with early breast cancer judged low-risk (ie, hormone receptor-positive, axillary node-negative, T1-T2 up to 3 cm at the longest dimension, and clear margins; grade 3 tumour histology or lymphovascular invasion, but not both, were permitted), who had had breast-conserving surgery and were receiving adjuvant endocrine treatment, were recruited into a phase 3 randomised controlled trial at 76 centres in four countries. Eligible patients were randomly assigned to either whole-breast radiotherapy (40-50 Gy in 15-25 fractions) or no radiotherapy by computer-generated permuted block randomisation, stratified by centre, with a block size of four. The primary endpoint was ipsilateral breast tumour recurrence. Follow-up continues and will end at the 10-year anniversary of the last randomised patient. Analyses were done by intention to treat. The trial is registered on ISRCTN.com, number ISRCTN95889329. 658 women who had undergone breast-conserving surgery and who were receiving adjuvant endocrine treatment were randomly assigned to receive whole-breast irradiation and 668 were allocated to no further treatment. After median follow-up of 5 years (IQR 3·84-6·05), ipsilateral breast tumour recurrence was 1·3% (95% CI 0·2-2·3; n=5) in women assigned to whole-breast radiotherapy and 4·1% (2·4-5·7; n=26) in those assigned no radiotherapy (p=0·0002). Compared with women allocated to whole-breast radiotherapy, the univariate hazard ratio for ipsilateral breast tumour recurrence in women assigned to no radiotherapy was 5·19 (95% CI 1·99-13·52; p=0·0007). No differences in

    Purpose. To assess feasibility, efficacy, toxicity, and cosmetic results of intraoperative radiotherapy (IORT) with electrons delivered by standard linear accelerators (Linacs) during breast conserving surgeries for early infiltrating breast cancer (BC) treatment. Materials and Methods. A total of 152 patients with invasive ductal carcinoma (T ≤ 3.0 cm) at low risk for local relapses were treated. All had unicentric lesions by imaging methods and negative sentinel node. After a wide local excision, 21 Gy were delivered on the parenchyma target volume with electron beams. Local recurrences (LR), survival, toxicity, and cosmetic outcomes were analyzed. Results. The median age was 58.3 years (range 40–85); median follow-up was 50.7 months (range 12–101.5). There were 5 cases with LR, 2 cases with distant metastases, and 2 cases with deaths related to BC. The cumulative incidence rates of LR, distant metastases, and BC death were 3.2%, 1.5%, and 1.5%, respectively. Complications were rare, and the cosmetic results were excellent or good in most of the patients. Conclusions. IORT with electrons delivered by standard Linacs is feasible, efficient, and well tolerated and seems to be beneficial for selected patients with early infiltrating BC. PMID:25587452

    Scarring in the tumor bed may mask or mimic local recurrence of tumor on surveillance mammography. Type of surgical closure technique used during lumpectomy may impact the pattern or density of scar tissue apparent in the tumor bed on mammography. This study sought to determine whether surgical closure type affects tumor-bed scar formation and impacts interpretation of surveillance mammography in women treated with breast-conserving therapy for early-stage breast cancer. One hundred women who received breast-conserving therapy were selected; 99 of them had 2-year post-treatment mammograms for the treated breast. Craniocaudal and mediolateral oblique views were reviewed by 3 subspecialty radiologists who routinely read mammograms. The mammograms were scored on 5-point scales for overall breast density and scarring within the tumor bed. The analyses did not demonstrate greater scarring or density in breast status post superficial closure compared with breast status post full-thickness closure, or vice versa (P > 0.05 for scarring and density). There were no detectable differences between the 2 closure techniques either within the data from individual reviewers, within the composite data for the entire group of reviewers, or in instances where 2 of 3 reviewers agreed (P > 0.05). There was significant interobserver variability in scoring among the mammographers for both scarring (P = 0.001) and density (P < 0.0001). Based on our study of the 2-year post-treatment mammograms, there was no evidence that closure technique impacts degree of scarring in the tumor bed. However, striking interobserver variability in scoring density and scarring was noted.

    Most of the blood tests aiming for breast cancer screening rely on quantification of a single or few biomarkers. The aim of this study was to evaluate the feasibility of detecting breast cancer by analyzing the total biochemical composition of plasma as well as peripheral blood mononuclear cells (PBMCs) using infrared spectroscopy. Blood was collected from 29 patients with confirmed breast cancer and 30 controls with benign or no breast tumors, undergoing screening for breast cancer. PBMCs and plasma were isolated and dried on a zinc selenide slide and measured under a Fourier transform infrared (FTIR) microscope to obtain their infrared absorption spectra. Differences in the spectra of PBMCs and plasma between the groups were analyzed as well as the specific influence of the relevant pathological characteristics of the cancer patients. Several bands in the FTIR spectra of both blood components significantly distinguished patients with and without cancer. Employing feature extraction with quadratic discriminant analysis, a sensitivity of ~90 % and a specificity of ~80 % for breast cancer detection was achieved. These results were confirmed by Monte Carlo cross-validation. Further analysis of the cancer group revealed an influence of several clinical parameters, such as the involvement of lymph nodes, on the infrared spectra, with each blood component affected by different parameters. The present preliminary study suggests that FTIR spectroscopy of PBMCs and plasma is a potentially feasible and efficient tool for the early detection of breast neoplasms. An important application of our study is the distinction between benign lesions (considered as part of the non-cancer group) and malignant tumors thus reducing false positive results at screening. Furthermore, the correlation of specific spectral changes with clinical parameters of cancer patients indicates for possible contribution to diagnosis and prognosis.

    The detection of circulating tumor cells (CTC) in breast cancer is strongly associated with disease relapse. Since it is unclear whether all CTCs are capable of generating metastasis, we investigated their apoptotic and proliferative status in 56 CTC-positive (29 early and 27 metastatic) patients with breast cancer. Double-staining immunofluorescence experiments were carried out in peripheral blood mononuclear cells (PBMC) cytospins, using the pancytokeratin A45-B/B3 antibody and either M30 (apoptotic marker) or Ki67 (proliferation marker) antibodies. Apoptosis was also evaluated using a polycaspase detection kit. Patients with metastatic disease had significantly lower numbers of apoptotic CTCs compared with patients with early breast cancer (polycaspase kit: 8.1% vs. 47.4% of the total CTC number; P = 0.0001; M30-antibody: 32.1% vs. 76.63%; P = 0.002). The median percentage of apoptotic CTCs per patient was also lower in patients with advanced compared with those with early disease (polycaspase kit: 0% vs. 53.6%; M30-antibody: 15% vs. 80%). Ki67-positive CTCs were identified in 51.7% and 44% of patients with early and metastatic disease, respectively. Adjuvant chemotherapy reduced both the number of CTCs per patient and the number of proliferating CTCs (63.9% vs. 30%). In conclusion, apoptotic CTCs could be detected in patients with breast cancer irrespective of their clinical status, though the incidence of detection is higher in early compared with metastatic patients. The detection of CTCs that survive despite adjuvant therapy implies that CTC elimination should be attempted using agents targeting their distinctive molecular characteristics.

  10. Quasi-multistatic MIST beamforming for the early detection of breast cancer.

    Microwave imaging via space-time (MIST) beamforming has been shown to be one of the most promising imaging modalities for detecting small malignant breast tumors. This paper outlines two modifications to the MIST system developed by Hagness for the early detection of breast cancer, resulting in a quasi-multistatic MIST beamformer (multi-MIST). Multistatic MIST beamforming involves illuminating the breast with an ultrawideband (UWB) signal from one antenna while collecting the reflections at an array of antennas, as opposed to traditional monostatic MIST beamforming where only the transmitting antenna records the reflections from the breast. In order to process the multistatic data, traditional data-adaptive artifact removal algorithms have to be modified to accommodate signals from all antennas. Also, the MIST beamforming algorithm, which spatially focuses the signal and compensates for frequency-dependent propagation effects, has to be modified. The algorithms are tested on a 2-D anatomically accurate finite-difference time-domain model of the breast. The multi-MIST beamformer described here is shown to offer an improved signal to clutter ratio when compared to the traditional monostatic MIST beamformer.

    The analysis of the causes that have given rise to a change in tendency in the incidence and mortality rates of breast cancer in the last few decades generates important revelations regarding the role of breast screening, the regular application of adjuvant therapies and the change of risk factors. The benefits of early detection have been accompanied by certain adverse effects, even in terms of an excessive number of prophylactic mastectomies. Recently, several updates have been published on the recommendations in breast cancer screening at an international level. On the other hand, the advances in genomics have made it possible to establish a new molecular classification of breast cancer. Our aim is to present an updated overview of the epidemiological situation of breast cancer, as well as some relevant issues from the point of view of diagnosis, such as molecular classification and different strategies for both population-based and opportunistic screening.

    Research in the fields of surgical, medical, and radiation oncology has changed the landscape of neoadjuvant therapy in breast cancer, yet many areas of controversy still exist. When considering whether a patient is a candidate for neoadjuvant therapy, ideally the initial assessment should be multidisciplinary in nature and should include clinical, radiographic, and pathologic evaluation. Optimization of systemic therapy is dependent upon identifying the patient's breast cancer subtype; the best approach may include targeted agents, as well as the determination of eligibility for enrollment into clinical trials that incorporate novel therapeutics or predictive biomarkers. This article will review a variety of surgical and radiation-based strategies for management of early-stage breast cancer, including surgical options involving the breast and axilla, and the role of radiation based on response to systemic therapy. Key areas of controversy include the ideal systemic treatment for different breast cancer subtypes, the surgical and radiotherapeutic approaches for management of the axilla, and the role of pathologic response rates as a surrogate for survival in drug development.

    Conservation of the breast in early breast cancer with limited resection and radiation is proving to be as effective as modified radical mastectomy in survival and in loco-regional control. Management at the University of Kansas Medical Center consists of an interstitial implant at the time of lumpectomy to facilitate perioperative irradiation with Iridium-192 to the tumor bed. An axillary node dissection is also performed at that time. Two to 3 weeks later external beam irradiation is delivered to the entire breast. One hundred and twenty-three breasts in 120 patients have been treated between June 1982 and June 1986. There were 49 pathological Stage I, 63 Stage II, 8 Stage III carcinomas, and 3 carcinomas in situ, consisting of 72 T1, 43 T2, 5 T3, and 3 TIS lesions. Patients have been followed for a median of 30 months. One patient had a ''true'' recurrence in the breast. Another patient developed recurrence in a different quadrant. Ninety percent of the patients had good to excellent cosmetic results, 7% were considered fair, and 3% had poor results. Seven patients developed mild arm edema, 4 were found to have moderate edema, and 1 had severe arm edema. Our preliminary results indicate that interstitial irradiation immediately after excision results in excellent local control, with very satisfactory cosmesis and no morbidity due to the simultaneous excision and irradiation.

    Purpose: Intensity modulated radiation therapy (IMRT) is a newer method of radiation therapy (RT) that has been increasingly adopted as an adjuvant treatment after breast-conserving surgery (BCS). IMRT may result in improved cosmesis compared to standard RT, although at greater expense. To investigate the adoption of IMRT, we examined trends and factors associated with IMRT in women under the age of 65 with early stage breast cancer. Methods and Materials: We performed a retrospective study of early stage breast cancer patients treated with BCS followed by whole-breast irradiation (WBI) who were ≤65 years old in the National Cancer Data Base from 2004 to 2011. We used logistic regression to identify factors associated with receipt of IMRT (vs standard RT). Results: We identified 11,089 women with early breast cancer (9.6%) who were treated with IMRT and 104,448 (90.4%) who were treated with standard RT, after BCS. The proportion of WBI patients receiving IMRT increased yearly from 2004 to 2009, with 5.3% of WBI patients receiving IMRT in 2004 and 11.6% receiving IMRT in 2009. Further use of IMRT declined afterward, with the proportion remaining steady at 11.0% and 10.7% in 2010 and 2011, respectively. Patients treated in nonacademic community centers were more likely to receive IMRT (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.30-1.43 for nonacademic vs academic center). Compared to privately insured patients, the uninsured patients (OR, 0.81; 95% CI, 0.70-0.95) and those with Medicaid insurance (OR, 0.87; 95% CI, 0.79-0.95) were less likely to receive IMRT. Conclusions: The use of IMRT rose from 2004 to 2009 and then stabilized. Important nonclinical factors associated with IMRT use included facility type and insurance status.

    Estrogen induced proliferation of mutant cells is widely understood to be the one of major risk determining factor in the development of breast cancer. Hence determination of the Estrogen Receptor[ER] status is of paramount importance if cancer pathogenesis is to be detected and rectified at an early stage. Near Infrared Fluorescence [NIRf] Molecular Optical Imaging is emerging as a powerful tool to monitor bio-molecular changes in living subjects. We discuss pre-clinical results in our efforts to develop an optical imaging diagnostic modality for the early detection of breast cancer. We have successfully carried out the synthesis and characterization of a novel target-specific NIRf dye conjugate aimed at measuring Estrogen Receptor[ER] status. The conjugate was synthesized by ester formation between 17-β estradiol and a hydrophilic derivative of Indocyanine Green (ICG) cyanine dye, bis-1,1-(4-sulfobutyl) indotricarbocyanine-5-carboxylic acid, sodium salt. In-vitro studies regarding specific binding and endocytocis of the dye performed on ER+ve [MCF-7] and control [MDA-MB-231] adenocarcinoma breast cancer cell lines clearly indicated nuclear localization of the dye for MCF-7 as compared to plasma level staining for MDA-MB-231. Furthermore, MCF-7 cells showed ~4.5-fold increase in fluorescence signal intensity compared to MDA-MB-231. A 3-D mesh model mimicking the human breast placed in a parallel-plate DOT Scanner is created to examine the in-vivo efficacy of the dye before proceeding with clinical trials. Photon migration and florescence flux intensity is modeled using the finite-element method with the coefficients (quantum yield, molar extinction co-efficient etc.) pertaining to the dye as obtained from photo-physical and in-vitro studies. We conclude by stating that this lipophilic dye can be potentially used as a target specific exogenous contrast agent in molecular optical imaging for early detection of breast cancer.

    Objective To explore barriers to early presentation and diagnosis with breast cancer among black women. Design Systematic review. Methods We searched multiple bibliographic databases (January 1991–February 2013) for primary research, published in English, conducted in developed countries and investigating barriers to early presentation and diagnosis with symptomatic breast cancer among black women (≥18 years). Studies were excluded if they did not report separate findings by ethnic group or gender, only reported differences in time to presentation/diagnosis, or reported on interventions and barriers to cancer screening. We followed Cochrane and PRISMA guidance to identify relevant research. Findings were integrated through thematic synthesis. Designs of quantitative studies made meta-analysis impossible. Results We identified 18 studies (6183 participants). Delay was multifactorial, individual and complex. Factors contributing to delay included: poor symptom and risk factor knowledge; fear of detecting breast abnormality; fear of cancer treatments; fear of partner abandonment; embarrassment disclosing symptoms to healthcare professionals; taboo and stigmatism. Presentation appears quicker following disclosure. Influence of fatalism and religiosity on delay is unclear from evidence in these studies. We compared older studies (≥10 years) with newer ones (<10 years) to determine changes over time. In older studies, delaying factors included: inaccessibility of healthcare services; competing priorities and concerns about partner abandonment. Partner abandonment was studied in older studies but not in newer ones. Comparisons of healthy women and cancer populations revealed differences between how people perceive they would behave, and actually behave, on finding breast abnormality. Conclusions Strategies to improve early presentation and diagnosis with breast cancer among black women need to address symptom recognition and interpretation of risk, as well as

    Breast-conserving surgery (BCS) is increasingly employed for the treatment of early stage breast cancer. One of the key challenges in BCS is to ensure complete removal of the tumour while conserving as much healthy tissue as possible. In this study we have investigated the potential of Raman micro-spectroscopy (RMS) for automated intra-operative evaluation of tumour excision. First, a multivariate classification model based on Raman spectra of normal and malignant breast tissue samples was built and achieved diagnosis of mammary ductal carcinoma (DC) with 95.6% sensitivity and 96.2% specificity (5-fold cross-validation). The tumour regions were discriminated from the healthy tissue structures based on increased concentration of nucleic acids and reduced concentration of collagen and fat. The multivariate classification model was then applied to sections from fresh tissue of new patients to produce diagnosis images for DC. The diagnosis images obtained by raster scanning RMS were in agreement with the conventional histopathology diagnosis but were limited to long data acquisition times (typically 10 000 spectra mm-2, which is equivalent to ~5 h mm-2). Selective-sampling based on integrated auto-fluorescence imaging and Raman spectroscopy was used to reduce the number of Raman spectra to ~20 spectra mm-2, which is equivalent to an acquisition time of ~15 min for 5 × 5 mm2 tissue samples. This study suggests that selective-sampling Raman microscopy has the potential to provide a rapid and objective intra-operative method to detect mammary carcinoma in tissue and assess resection margins.

    For women undergoing breast conservation therapy (BCT), the added value of breast magnetic resonance imaging (MRI) at the time of initial diagnosis remains controversial. The current study was performed to determine long-term outcomes after BCT for women with and without pretreatment breast MRI. Between 1992 and 2001, a total of 755 women with ductal carcinoma in situ or early-stage invasive breast cancer underwent breast-conserving surgery (with axillary lymph node staging for invasive carcinoma) followed by definitive breast radiotherapy. Evaluation at the time of the initial diagnosis included conventional mammography in all subjects and breast MRI in 215 women (28%). Clinical, pathologic, and treatment characteristics were comparable for patients with and without breast MRI. Outcomes were determined using the Kaplan-Meier method and compared using the log-rank method. At a median follow-up of 13.8 years, there were 49 local failures (15 women with and 34 women without breast MRI, respectively). The 15-year local failure rates were 8% for women with and 8% for women without MRI (P = .59). There also were no differences noted between women with and without breast MRI with regard to 15-year rates of overall survival (77% vs 71%; P = .24), freedom from distant metastases (86% vs 90%; P = .08), and contralateral breast cancer (10% vs 8%; P = .10). Multivariate analysis demonstrated no significant impact of breast MRI on local failure (P = .96). Breast MRI during the initial evaluation for BCT appears to have no significant impact on 15-year rates for local control, overall survival, freedom from distant metastases, or contralateral breast cancer. The routine use of pretreatment breast MRI is not indicated for patients undergoing BCT. Cancer 2017;123:1324-1332. © 2016 American Cancer Society. © 2016 American Cancer Society.

    Patients with early breast cancer (T1-2 N0-1) can be treated by lumpectomy and irradiation with a local control and survival equal to more radical surgery. Between 1982 and 1988, 323 patients with early breast cancer were treated, when possible, with Ir-192 implants at the time of lumpectomy to a local dose of 2000 cGy in 40-50 hours. Ten to 14 days later, the whole breast was treated to 4500 cGy at 180 per fraction in 5 weeks. The 6-year actuarial survival for stages I and II disease was 98% and 91%, respectively, and the recurrence-free survival was 96% and 98%, respectively. When these 323 patients were evaluated by T status, a local control of 97% was the same for T1 and T2 lesions. The cosmetic results were good to excellent in 95% of the patients. This approach has improved our ability to accurately place the boost dose in the breast.

    Breast milk carotenoids provide neonates with a source of vitamin A and potentially, oxidative stress protection and other health benefits. Chlorella, which has high levels of carotenoids such as lutein, zeaxanthin and β-carotene, is an effective dietary source of carotenoids for humans. In this study, the effect of maternal supplementation with Chlorella on carotenoid levels in breast milk at early lactation was investigated. Ten healthy, pregnant women received 6 g of Chlorella daily from gestational week 16-20 until the day of delivery (Chlorella group); ten others did not (control group). Among the carotenoids detected in breast milk, lutein, zeaxanthin and β-carotene concentrations in the Chlorella group were 2.6-fold (p = 0.001), 2.7-fold (p = 0.001) and 1.7-fold (p = 0.049) higher, respectively, than those in the control group. Our study shows that Chlorella intake during pregnancy is effective in improving the carotenoid status of breast milk at early lactation.

    Taxanes are highly active chemotherapeutic agents used in the treatment of early-stage and metastatic breast cancer. Novel formulations have been developed to improve efficacy and decrease toxicity associated with these cytotoxic agents. nab-Paclitaxel is a biologically interactive, solvent-free, 130-nm-sized albumin-bound paclitaxel, developed to avoid the Cremophor vehicle used in solvent-based paclitaxel. Based on a pivotal phase 3 study, nab-paclitaxel was shown to be safely infused at a significantly higher dose of paclitaxel than the doses used with standard paclitaxel therapy, and had a shorter infusion time, no premedication, and higher response rates. It is now approved in the United States for treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant therapy, and has demonstrated promising efficacy and favorable tolerability. Recently, several phase 2 and 3 studies have suggested a role for nab-paclitaxel in combination with biologically targeted agents for the treatment of early- and late-stage breast cancer. This review will discuss the findings of clinical trials evaluating nab-paclitaxel in combination with biologically targeted therapeutic agents for breast cancer in the neoadjuvant, adjuvant, and metastatic settings.

    Adjuvant systemic therapy along with screening has been key to the observed improvements in disease-free and overall survival (DFS/OS) in breast cancer. Improvements in overall survival already take into account therapy related toxicities that can result in death. However, this measure alone does not adequately capture the impact on health-related quality of life. Therefore, it is important to examine the prevalence, frequency and short/long-term impact of therapy-related toxicities, identify patients who might be at greatest risk. Ultimately decisions regarding expected therapy benefits (relative and absolute percentage improvements in DFS/OS) must be made against a background of known potential harms. For many patients with early breast cancer (EBC), their risk of recurrence is not zero but is small. At the same time, for many therapies for early stage breast cancer, the risk of serious side effects is small but is not zero. As we better understand the long-term side effects of adjuvant chemotherapy and targeted therapy, it becomes critical to integrate our growing understanding of breast cancer biology with standard high-quality histopathologic measures to better identify the patients most likely to benefit from the various options for combined multimodality therapy. Hence, we must strive against the notion of recommending adjuvant systemic chemotherapy "just in case."

    The purpose of this study was to determine the effect of breast cancer fear levels of female seasonal agricultural laborers between ages 40 and 60 on breast cancer early-diagnosis behaviors and perceptions. This is a cross-sectional study. The data of the study were collected between February and September 2014 in Şanlıurfa, Turkey. A sample of the study group consisted of 350 women. The data were assessed by using SPSS 16.0 statistics package software. Descriptive statistics, t test, chi-square, and correlation analysis were used to analyze the data. Considering that breast cancer fear levels are effective on the breast cancer early-diagnosis behaviors and health beliefs, it can be recommended for the health care staff to carry out initiative works to reduce the fear levels.

  6. Chemotherapy in Early Breast Cancer: When, How and Which One?

    2014-01-01

    Summary The efficacy of chemotherapy depends on the level of risk of the individual patient. Because of this, careful estimation of the risk level is mandatory. In addition to well-established clinicopathological factors, validated gene expression signatures might be useful in selected patients if all other criteria are inconclusive for therapeutic decision-making. If indicated, chemotherapy can be used either after surgery (adjuvant) or before surgery (neoadjuvant). Both approaches lead to comparable long-term survival. The neoadjuvant setting offers the additional opportunity for elaborate translational studies to develop and validate predictive biomarkers and to discover mechanisms of resistance to therapy. If possible, chemotherapy regimens should include both anthracyclines and taxanes. Docetaxel should be used every 3 weeks; better tolerability with equivalent efficacy favors the concurrent over the sequential approach. Paclitaxel, on the other hand, should be administered sequentially, either weekly or every 2 weeks. Especially, intense dose-dense sequential chemotherapy with granulocyte colony-stimulating factor support is very effective in high-risk breast cancer patients. In order to decrease toxicities, anthracycline-free regimens or a shortening of the duration of adjuvant chemotherapy are potential options that should be further explored. PMID:25177256

    This is the third in a series dealing with chronic diseases and early exposure to airborne mixtures from industrial releases. The purpose of this study is to increase the understanding of previously unconsidered factors in the physical environment potentially acting as risk factors for female breast cancer. Data are from the Environmental Quality Database containing lifetime residential records for about 20,000 cases, with 1 of 15 cancers and about 5000 controls. Subjects resided within 25 km of all kraft mills, sulfite mills, coke ovens, oil refineries, copper, nickel and lead/zinc smelters operating in Canada in 1967-1970, and were aged <31 years. Subjects are exposed at home to simultaneous counter-current plumes of dioxin congeners and dimethyl sulfate (DMS) during the exposure period. DMS concentration increases with time of flight from the source and [SO(2)] at 2 km. For all source types the number of cancers in an age cohort declines as the age of the cohort increases. The number of cases less than the median distance is less than the number of cases greater than the median distance. This supports the presence of a new source of risk with an origin in the plume. The crude rate of breast cancer, averaged over the 25 km of the study area for each age cohort <31 years of age, as well as source type, is least when the conditions of initial exposure are [SO(2)] > or = [DMS] and increases as [DMS] increases. The probability of an adverse effect from early, intermittent and simultaneous exposure to Dioxin and DMS, manifesting as a breast cancer after a latency period of as little as 26 years, is a function of age of first exposure, distance from the source and source type. The most susceptible age cohorts are the youngest.

    Since the inception of the Centers for Disease Control and Prevention (CDC) National Breast and Cervical Cancer Early Detection Program (NBCCEDP) in 1990, partnerships have played a significant role in providing breast and cervical cancer screening and early detection to uninsured and underinsured women. The state, tribal, and territorial NBCCEDP grantees have shared resources and responsibilities with a variety of partners (eg, community-based organizations, government agencies, tribes, health care systems, companies, professional organizations) to achieve common goals. National partners, such as the American Cancer Society, Susan G. Komen for the Cure, and the Avon Foundation for Women, have provided funding, lobbied for national and state funding, supported outreach and education activities, and provided treatment referral services for the programs. This article provides an overview of grantee partnerships to illustrate the effects, successes, and challenges of these partnerships and how they have affected the populations served by the program.

    Purpose: To evaluate survival outcomes of young women with early-stage breast cancer treated with breast conservation therapy (BCT) or mastectomy, using a large, population-based database. Methods and Materials: Using the Surveillance, Epidemiology, and End Results (SEER) database, information was obtained for all female patients, ages 20 to 39 years old, diagnosed with T1-2 N0-1 M0 breast cancer between 1990 and 2007, who underwent either BCT (lumpectomy and radiation treatment) or mastectomy. Multivariable and matched pair analyses were performed to compare overall survival (OS) and cause-specific survival (CSS) of patients undergoing BCT and mastectomy. Results: A total of 14,764 women were identified, of whom 45% received BCT and 55% received mastectomy. Median follow-up was 5.7 years (range, 0.5-17.9 years). After we accounted for all patient and tumor characteristics, multivariable analysis found that BCT resulted in OS (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.83-1.04; p = 0.16) and CSS (HR, 0.93; CI, 0.83-1.05; p = 0.26) similar to that of mastectomy. Matched pair analysis, including 4,644 BCT and mastectomy patients, confirmed no difference in OS or CSS: the 5-, 10-, and15-year OS rates for BCT and mastectomy were 92.5%, 83.5%, and 77.0% and 91.9%, 83.6%, and 79.1%, respectively (p = 0.99), and the 5-, 10-, and 15-year CSS rates for BCT and mastectomy were 93.3%, 85.5%, and 79.9% and 92.5%, 85.5%, and 81.9%, respectively (p = 0.88). Conclusions: Our analysis of this population-based database suggests that young women with early-stage breast cancer have similar survival rates whether treated with BCT or mastectomy. These patients should be counseled appropriately regarding their treatment options and should not choose a mastectomy based on the assumption of improved survival.

    Coastal floods are a consistent threat to oceanfront countries, causing major human suffering and substantial economic losses. Climate change is exacerbating the problem. An early warning system is essential to mitigate the loss of life and property from coastal flooding. The purpose of this study is to develop a coastal flooding early warning system (CoFEWs) by integrating existing sea-state monitoring technology, numerical ocean forecasting models, historical database and experiences, as well as computer science. The proposed system has capability of offering data for the past, information for the present and future. The system was developed for the Taiwanese coast due to its frequent threat by typhoons. An operational system without any manual work is the basic requirement of the system. Integration of various data sources is the system kernel. Numerical ocean models play an important role within the system because they provide data for assessment of possible flooding. The regional wave model (SWAN) that nested with the large domain wave model (NWW III) is operationally set up for coastal wave forecasting, in addition to the storm surge predicted by a POM model. Data assimilation technology is incorporated for enhanced accuracy. A warning signal is presented when the storm water level that accumulated from astronomical tide, storm surge, and wave-induced run-up exceeds the alarm sea level. This warning system has been in practical use for coastal flooding damage mitigation in Taiwan for years. An example of the system operation during the Typhoon Haitung which struck Taiwan in 2005 is illustrated in this study.

    Purpose We tested the hypotheses that CHEK2*1100delC heterozygosity is associated with increased risk of early death, breast cancer–specific death, and risk of a second breast cancer in women with a first breast cancer. Patients and Methods From 22 studies participating in the Breast Cancer Association Consortium, 25,571 white women with invasive breast cancer were genotyped for CHEK2*1100delC and observed for up to 20 years (median, 6.6 years). We examined risk of early death and breast cancer–specific death by estrogen receptor status and risk of a second breast cancer after a first breast cancer in prospective studies. Results CHEK2*1100delC heterozygosity was found in 459 patients (1.8%). In women with estrogen receptor–positive breast cancer, multifactorially adjusted hazard ratios for heterozygotes versus noncarriers were 1.43 (95% CI, 1.12 to 1.82; log-rank P = .004) for early death and 1.63 (95% CI, 1.24 to 2.15; log-rank P < .001) for breast cancer–specific death. In all women, hazard ratio for a second breast cancer was 2.77 (95% CI, 2.00 to 3.83; log-rank P < .001) increasing to 3.52 (95% CI, 2.35 to 5.27; log-rank P < .001) in women with estrogen receptor–positive first breast cancer only. Conclusion Among women with estrogen receptor–positive breast cancer, CHEK2*1100delC heterozygosity was associated with a 1.4-fold risk of early death, a 1.6-fold risk of breast cancer–specific death, and a 3.5-fold risk of a second breast cancer. This is one of the few examples of a genetic factor that influences long-term prognosis being documented in an extensive series of women with breast cancer. PMID:23109706

    This study reports on monthly scans of healthy patient volunteers with the clinical prototype of a microwave imaging system. The system uses time-domain measurements, and incorporates a multistatic radar approach to imaging. It operates in the 2-4 GHz range and contains 16 wideband sensors embedded in a hemispherical dielectric radome. The system has been previously tested on tissue phantoms in controlled experiments. With this system prototype, we scanned 13 patients (26 breasts) over an eight-month period, collecting a total of 342 breast scans. The goal of the study described in this paper was to investigate how the system measurements are impacted by multiple factors that are unavoidable in monthly monitoring of human subjects. These factors include both biological variability (e.g., tissue variations due to hormonal changes or weight gain) and measurement variability (e.g., inconsistencies in patient positioning, system noise). For each patient breast, we process the results of the monthly scans to assess the variability in both the raw measured signals and in the generated images. The significance of this study is that it quantifies how much variability should be anticipated when conducting microwave breast imaging of a healthy patient over a longer period. This is an important step toward establishing the feasibility of the microwave radar imaging system for frequent monitoring of breast health.

    Weight gain is a well-known and unwanted complication of adjuvant chemotherapy in breast cancer. We observed that the female Turkish cancer patients frequently gain weight with adjuvant treatment of breast cancer and planned to examine the magnitude of this problem in early breast cancer patients treated at our hospital. A total of 176 early breast cancer patients who received their adjuvant systemic therapy in Marmara University Hospital between 2003 and 2007 are included in the study. We recorded their weight before and after chemotherapy and also a year after chemotherapy to find out whether the change with weight is transitory. We have also recorded demographic information, including the educational level, menopausal status, the type of chemotherapy or hormonal treatment administered stage of disease, marital status, occupation and the underlying diseases to analyze the relationship between change in weight and these parameters. Median age of patients was 53 and 72% of patients were postmenopausal. Educational level was equally distributed for primary education (27%), high school (40%), and university (33%). The majority of the patients (76%) was married, had two children (69%) and was housewife (60%). Family history of any cancer was high (32%). Most of the patients had stage II cancer (56%), received anthracyclines+/- taxane based chemotherapy (98%) and had no underlying disease (68%). The majority also did not smoke (73%) or drink alcohol (93%). A total of 67% and 72% patients gained weight upon completion and one year after completion of chemotherapy. Mean weight before the chemotherapy, upon completion of chemotherapy and one year after completion of chemotherapy were 68.9 kg, 70.6 kg (P = 0.000) and 71.9 kg (P = 0.000) respectively. Mean body mass index was 27.1 at baseline, 27.8 upon completion of chemotherapy (P = 0.000) and 28.3 one year after completion of chemotherapy (P = 0.000).

    Node (+) breast cancer represents over 40% of cases in older women and currently there is a debate whether adjuvant therapy for all older women is cost-effective. To evaluate if adjuvant treatment for early-stage (Stage I-IIIa) node (+) breast cancer with hormone therapy, chemotherapy, or combination therapy is cost-effective in older patients. A decision-analysis model for 65, 75, and 85 year-old female breast cancer patients using life tables integrated the cost of treatment in dollars and impact in length and quality of life. Both estrogen receptor (ER) (-) and (+) patients were considered. The primary data sources were meta-analysis from the Early Breast Cancer Trialists' Collaborative Group and the Red Book Average Wholesale Price for drugs. The cost of treatment in dollars and impact of quality of life was examined. Scenarios were used when treatment benefit was uncertain. The incremental cost-effectiveness of different treatment strategies were then compared and mapped graphically. Adjuvant therapy is cost-effective in 65 year-old women with early breast cancer. In a 75 year-old ER (+) patient, hormone therapy is cost-effective, $10,965/quality-adjusted life years (QALY), but chemotherapy was more cost-effective, $27,406/QALY, if one assumed it was as efficacious as in a 65 year-old woman. In a 75 year-old ER (-) patient, chemotherapy was cost-effective at $42,605 with the same assumption. In an 85 year-old ER (+) patient, hormone therapy was cost-effective, $26,463/QALY, if efficacy is not age-sensitive, but chemotherapy was not as cost-effective for either ER (+) or ER (-) patients. Treatment decisions for older breast cancer patients suffer from the lack of sufficient clinical trial data. Decision-analytic models can help policy makers who are faced with decisions about whether to support adjuvant therapy in older breast cancer patients and also outline the important parameters that need to be considered in such a decision.

    Spindle-shaped stromal cells, like carcinoma-associated fibroblasts and mesenchymal stem cells, influence tumor behavior and can serve as parameters in the clinical diagnosis, therapy, and prognosis of early breast cancer. Therefore, the aim of this study is to explore the clinicopathological significance of tumor necrosis factor-related apoptosis-induced ligand (TRAIL) receptors (Rs) 2 and 4 (TRAIL-R2 and R4), and interleukin-6 R (IL-6R) in spindle-shaped stromal cells, not associated with the vasculature, as prognostic determinants of early breast cancer patients. Receptors are able to trigger the migratory activity, among other functions, of these stromal cells. We conducted immunohistochemical analysis for the expression of these receptors in spindle-shaped stromal cells, not associated with the vasculature, of primary tumors from early invasive breast cancer patients, and analyzed their association with clinicopathological characteristics. Here, we demonstrate that the elevated levels of TRAIL-R2, TRAIL-R4, and IL-6R in these stromal cells were significantly associated with a higher risk of metastatic occurrence (p = 0.034, 0.026, and 0.006; respectively). Moreover, high expression of TRAIL-R4 was associated with shorter disease-free survival and metastasis-free survival (p = 0.013 and 0.019; respectively). Also, high expression of IL-6R was associated with shorter disease-free survival, metastasis-free survival, and overall survival (p = 0.003, 0.001, and 0.003; respectively). Multivariate analysis showed that IL-6R expression was an independent prognostic factor for disease-free survival and metastasis-free survival (p = 0.035). This study is the first to demonstrate that high levels of IL-6R expression in spindle-shaped stromal cells, not associated with the vasculature, could be used to identify early breast cancer patients with poor outcomes.

    A trial arrangement for mandatory early discharge for all normal multiparae was started in 1990 and the duration of breastfeeding was investigated by a questionnaire. 89 mothers who stayed at the hospital were compared to 113 mothers who were discharged within 24 hours after delivery. The latter group was also compared to 122 early discharged mothers who delivered 14-17 months after the trial arrangement had started. The three groups were comparable in all aspects. After four weeks a large proportion of the later discharged mothers were still breastfeeding compared to the other two groups (p < 0.001). This difference disappeared later, hence when comparing the total duration of breastfeeding no differences were found between the three groups.

    To assess cancers diagnosed and the stage of cancer at the time of diagnosis among low-income, under-insured, or uninsured women who received services through the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). Using the NBCCEDP database, we examined the number and percent of women diagnosed during 2009-2011 with in situ breast cancer, invasive breast cancer, and invasive cervical cancer by demographic and clinical characteristics, including age, race and ethnicity, test indication (screening or diagnostic), symptoms (for breast cancer), and screening history (for cervical cancer). We examined these characteristics by stage at diagnosis, a new variable included in the database obtained by linking with state-based central cancer registries. There were 11,569 women diagnosed with invasive breast cancer, 1,988 with in situ breast cancer, and 583 with invasive cervical cancer through the NBCCEDP. Women who reported breast symptoms or who had diagnostic mammography were more likely to be diagnosed with breast cancer, and at a later stage, than those who did not have symptoms or who had screening mammography. Women who had been rarely or never screened for cervical cancer were more likely to be diagnosed with cervical cancer, and at a later stage, than women who received regular screenings. Women served through the NBCCEDP who have not had prior screening or who have symptoms were more often diagnosed with late-stage disease.

    Background Breast cancer is the leading cause of cancer-related death among U.S. Hispanic women. Hispanics are less likely than non-Hispanic White women to be diagnosed at an early stage and survive breast cancer. Methods For this cross-sectional study, we assessed differences in breast cancer knowledge, attitudes, and screening practices between Hispanic women with (FH+) and without (FH−) a family history of breast cancer in three U.S.-Mexico border counties. Results Among 137 Hispanic women age 40 and older, FH+ women had levels of knowledge and attitudes about breast cancer similar to those of FH− women. FH+ participants were more likely to have ever performed breast self-examinations, although levels of compliance with screening guidelines did not significantly differ between FH+ and FH− groups. Conclusion U.S. Hispanic women with a family history of breast cancer constitute an at-risk group for which adhering to preventive screening guidelines could substantially reduce breast cancer mortality.

    Breast conserving therapy is a currently accepted method for managing patients with early stage breast cancer. However, approximately 7% of patients may develop loco-regional tumour recurrence within 5 years. We previously reported that expression of the 26S proteasome may be associated with radio-resistance. Here we aimed to analyse the 26S proteasome in a pilot series of early breast cancers and correlate the findings with loco-regional recurrence. Fourteen patients with early breast cancer who developed loco-regional recurrence within 4 years of completing breast conserving therapy were selected according to strict criteria and compared with those from 14 patients who were disease-free at 10 years. Decreased expression of the 26S proteasome was significantly associated with radio-resistance, manifested as the development of a loco-regional recurrence within 4 years of breast conserving therapy (p = 0.018). This small pilot study provides further suggestion that the 26S proteasome may be associated with response to radiotherapy.

    Purpose A recent large phase 3 trial demonstrated that the efficacy of accelerated partial-breast irradiation (APBI) in the treatment of early breast cancer is non-inferior to that of whole breast irradiation (WBI) commonly used in this indication. The aim of this study was to compare the costs of treatment with APBI and WBI in a population of patients after conserving surgery for early breast cancer, and to verify if the use of APBI can result in direct savings of a public payer. Material and methods The hereby presented cost analysis was based on the results of GEC-ESTRO trial. Expenditures for identified cost centers were estimated on the basis of reimbursement data for the public payer. After determining the average cost of early breast cancer treatment with APBI and WBI over a 5-year period, the variance in this parameter resulting from fluctuations in the price per single procedure was examined on univariate sensitivity analysis. Then, incremental cost-effectiveness ratio (ICER) was calculated to verify the cost against clinical outcome. Finally, a simulation of public payer’s expenditures for the treatment of early breast cancer with APBI and WBI in 2013 and 2025 has been conducted. Results The average cost of treatment with APBI is lower than for WBI, even assuming a potential increase in the unit price of the former procedure. There was no additional health benefit of WBI and the calculation of cost-effectiveness was based on the absolute difference in overall local control rate. However, this difference (0.92% vs. 1.44%) was fairly minimal and was not identified as statistically significant during 5 years. Conclusions The use of APBI as an alternative to WBI in the treatment of early breast cancer would substantially reduce healthcare expenditures in both 2013 and 2025, even assuming an increase in the price per single APBI procedure.

    Conventional anthracyclines play an essential role for the treatment of breast cancer and have potent cytotoxic activity, but are associated with severe toxicity. In metastatic breast cancer, pegylated liposomal doxorubicin (PLD) is a formulation with efficacy similar to conventional doxorubicin but with reduced toxicity. This multicenter study evaluated the efficacy and safety of PLD-based adjuvant chemotherapy for women with stage I-III operable breast cancer. One hundred and eighty women with stage I-III breast cancer who received PLD-based adjuvant chemotherapy at six different Institutions in Taiwan from February 2002 to March 2008 were included and followed-up until April 2015. Treatment efficacy was determined by disease-free survival (DFS) rate and safety was evaluated by adverse events. The 5- and 10-year DFS rates were 76.3 and 72.6%, respectively. Univariate analysis revealed that tumor size >5 cm (p=0.045; hazard ratio=3.31) and stage III (hazard ratio=3.54; p=0.019) were each associated with shorter DFS. Only stage III (hazard ratio=5.60; p=0.018) retained statistical significance with regard to DFS in the multivariate analysis. Grade 3/4 hematological toxicity was neutropenia (n=13; 7.2%). The women receiving PLD had low-grade 3 or 4 nausea/vomiting, mucositis, and alopecia. Grade 3 hand-foot syndrome occurred in three patients (1.7%). PLD could be considered an effective and safe alternative to conventional anthracyclines in the treatment of stage I-III operable breast cancer.

    S100P - low molecular weight acidic protein has been shown to be involved in processes of proliferation, survival, angiogenesis, multidrug resistance and metastasis in various human malignancies. In breast cancer, S100P expression is associated with immortalization of neoplastic cells and aggressive tumour behaviour, indicating that this protein may have adverse prognostic value. We analyzed nuclear and cytoplasmic expression of S100P in 85 stage II breast cancer patients with a median follow up of 17 years. Immunohistochemical reactions were performed on paraffin sections of primary tumours, using monoclonal antibodies against S100P. We also studied prognostic value of S100P mRNA expression using the KM plotter which assessed the effect of 22,277 genes on survival in 2422 breast cancer patients. Moreover, the relationship was examined between expression of S100P in cells of four breast cancer cell lines and their sensitivity to the 11 most frequently applied cytotoxic drugs. Univariate and multivariate analyses showed that higher expression of nuclear S100P (S100Pn) was typical for cases of a shorter overall survival and disease-free time. KM plotter analysis showed that elevated S100P expression was specific for cases of a relapse-free survival and distant metastases-free survival. No relationship could be documented between expression of S100P and sensitivity of breast cancer cells to cytostatic drugs. We demonstrated that a high S100Pn expression level was associated with poor survival in early stage breast cancer patients. Since preliminary data indicated that expression of S100P was up-regulated by activation of glucocorticoid receptor and several agents manifested potential to activate or inhibit S100P promoter activity, this protein might become a therapy target and warrants further studies with respect to its prognostic, predictive and potentially therapeutic value.

  7. Screening sensitivity and sojourn time from breast cancer early detection clinical trials: mammograms and physical examinations.

    To estimate sensitivities of breast cancer screening modalities and preclinical duration of the disease from eight breast cancer screening clinical trials. Screening programs invariably lead to diagnosis of disease before signs or symptoms are present. Two key quantities of screening programs are the sensitivity of the disease detection modality and the mean sojourn time (MST). The observed screening histories in a periodically screened cohort make it possible to estimate these quantities of interest. We applied recently developed statistical methods to data from eight randomized breast cancer screening trials to estimate the sensitivities of early detection modalities and MST. Moreover, when a screening trial involved two screening modalities, our methods enabled the estimation of the individual sensitivity of each screening modality. We analyzed breast cancer data from several screening trials and have relatively complete data from the Health Insurance Plan (HIP), Edinburgh, and two Canadian studies. The screening sensitivity for mammography, physical examination, and MST were, respectively, HIP: 0.39, 0.47, and 2.5 years; Edinburgh: 0.63, 0.40, and 4.3 years; Canadian (age 40 to 49 at entry): 0.61, 0.59, and 1.9 years; Canadian (age 50 to 59 at entry): 0.66, 0.39, and 3.1 years. The public debate on early breast cancer detection is mainly centered on mammograms. However, the current study indicates that a physical examination is of comparable importance. Cautious interpretation of trial differences is required as a result of various experimental designs and the age dependency of screening sensitivity and MST.

    Previous studies suggest beta-adrenergic receptor (β-AR) antagonists (β-blockers) decrease breast cancer progression, tumor metastasis, and patient mortality; however the mechanism for this is unknown. Immunohistochemical analysis of normal and malignant breast tissue revealed overexpression of β1-AR and β3-AR in breast cancer. A retrospective cross-sectional study of 404 breast cancer patients was performed to determine the effect of β-blocker usage on tumor proliferation. Our analysis revealed that non-selective β-blockers, but not selective β-blockers, reduced tumor proliferation by 66% (p < 0.0001) in early stage breast cancer compared to non-users. We tested the efficacy of propranolol on an early stage breast cancer patient, and quantified the tumor proliferative index before and after treatment, revealing a propranolol-mediated 23% reduction (p = 0.02) in Ki67 positive tumor cells over a three-week period. The anti-proliferative effects of β-blockers were measured in a panel of breast cancer lines, demonstrating that mammary epithelial cells were resistant to propranolol, and that most breast cancer cell lines displayed dose dependent viability decreases following treatment. Selective β-blockers alone or in combination were not as effective as propranolol at reducing breast cancer cell proliferation. Molecular analysis revealed that propranolol treatment of the SK-BR-3 breast cancer line, which showed high sensitivity to beta blockade, led to a reduction in Ki67 protein expression, decreased phosphorylation of the mitogenic signaling regulators p44/42 MAPK, p38 MAPK, JNK, and CREB, increased phosphorylation of the cell survival/apoptosis regulators AKT, p53, and GSK3β. In conclusion, use of non-selective β-blockers in patients with early stage breast cancer may lead to decreased tumor proliferation. PMID:28031536

    Early discontinuation of aromatase inhibitors (AIs) is common and leads to poor outcomes but is challenging to predict. In the Exemestane and Letrozole Pharmacogenetics trial, a high rate of early discontinuation due to intolerance was observed. We hypothesized that early changes in patient-reported outcomes (PROs) predict AI discontinuation and that biochemical factors are associated with changes in PROs. Postmenopausal women with early-stage breast cancer enrolled in a prospective randomized trial of exemestane versus letrozole completed questionnaires at baseline and serially over 24 months to assess overall quality of life (EuroQOL Visual Analog Scale [VAS]); mood; and multiple symptoms, including a musculoskeletal symptom cluster. A joint mixed-effects/survival model was used to estimate the effect of the change in PROs on AI discontinuation. Associations between biochemical factors and change in PROs were examined. A total of 490 patients were analyzed. Worsening of EuroQOL VAS and the musculoskeletal cluster were associated with the highest risk for early discontinuation (hazard ratio [HR], 2.77 [95% confidence interval (CI), 2.72-2.81; p = .015]; HR, 4.39 [95% CI, 2.40-8.02; p < .0001], respectively). Pharmacokinetics and estrogen metabolism were not consistently associated with change in PRO measures. No clinically significant differences in any PRO between AIs were observed. Changes in PROs early during AI therapy were associated with treatment discontinuation. Identification of these changes could be used to target interventions in patients at high risk for early discontinuation. Early changes in patient-reported outcomes (PROs) can predict nonpersistence to aromatase inhibitor therapy. If used in clinical practice, PROs might identify women at highest risk for early discontinuation and allow for interventions to improve tolerance before significant toxicities develop. Further research is needed to improve capturing PROs in routine clinical practice.

    Breast cancer-related lymphedema (BCRL) has become an increasingly important clinical issue as noted by the recent update of the 2015 NCCN breast cancer guidelines which recommends to "educate, monitor, and refer for lymphedema management." The purpose of this review was to examine the literature regarding early detection and management of BCRL in order to (1) better characterize the benefit of proactive surveillance and intervention, (2) clarify the optimal monitoring techniques, and (3) help better define patient groups most likely to benefit from surveillance programs. A Medline search was conducted for the years 1992-2015 to identify articles addressing early detection and management of BCRL. After an initial search, 127 articles were identified, with 13 of these studies focused on early intervention (three randomized (level of evidence 1), four prospective (level of evidence 2-3), six retrospective trials (level of evidence 4)). Data from two, small (n = 185 cases), randomized trials with limited follow-up demonstrated a benefit to early intervention (physiotherapy, manual lymphatic drainage) with regard to reducing the rate of chronic BCRL (>50% reduction) with two additional studies underway (n = 1280). These findings were confirmed by larger prospective and retrospective series. Several studies were identified that demonstrate that newer diagnostic modalities (bioimpedance spectroscopy, perometry) have increased sensitivity allowing for the earlier detection of BCRL. Current data support the development of surveillance programs geared toward the early detection and management of BCRL in part due to newer, more sensitive diagnostic modalities.

    Purpose: To evaluate the effect of an ipsilateral breast tumor recurrence (IBTR) after breast-conservation therapy (BCT) on survival. Methods and Materials: One hundred twenty-one women were randomized to BCT. Patients with an IBTR were analyzed to determine survival. Analysis was performed with Kaplan-Meier estimates, log-rank tests, and time-dependent covariate Cox models. Results: At a median follow-up of 18.4 years, 27 patients had an IBTR. The median survival time after IBTR was 13.1 years. The 5-year survival rate was 91.8% (95% confidence interval [CI], 81.5-100%). The 10-year survival rate was 54.3% (95% CI, 35.8-82.6%). According to a Cox model with time-dependent covariates, the hazard ratio or relative risk of dying for those with an IBTR at <5.3 years after BCT relative to patients without an IBTR after BCT is 1.47 (95% CI, 1.02-2.12%; p = 0.04). The hazard ratio for those who relapse after 5.3 years is 0.59 (95% CI, 0.22-1.61%; p = 0.31). Age at randomization, original tumor size, and the presence of positive regional nodes at initial presentation were not found to be associated with decreased survival. Conclusions: There seems to be a significant association of early IBTR after BCT with decreased survival. Local control should be maximized.

    Selection of the treatment method in breast cancer patients and its consequences may affect their quality of life through somatic, psychical, and social factors. The aim of the study was early evaluation of the quality of life of women after mastectomy vs. breast conserving surgery. The study included 100 women aged 31 to 79 years (mean: 57) who underwent surgery due to breast cancer (amputation: 52; breast conserving surgery: 48 women) at the Cancer Centre in Bydgoszcz in 2014. The QLQ C-30 and QLQ BR-23 questionnaires were used to evaluate the quality of life of the patients 3 months after surgery. In the Global Health Status/QoL domain, the mean score for women after amputation and breast conserving surgery was 49 and 53, respectively; for Physical Functioning, the scores were 70 and 75, and for Role Functioning, 62 and 68, respectively. For Cognitive Functioning, the mean score was 74 and 73; for Emotional Functioning - 62 and 68, and for Social Functioning 64 and 60, respectively. The difference in the arm symptoms domain was significant at 46 and 33 points, respectively (p = 0.004). The patients treated with breast conserving surgery had a better body image than women after amputation - the mean score was 52 and 66, respectively (p = 0.01). With respect to Global Health Status/QoL and Physical Functioning, the quality of life of women in the early postoperative period was similar in women after breast amputation and those who underwent breast conserving surgery. Patients treated with breast conserving surgery had a better score for body image, while those who underwent amputation more often suffered from arm symptoms, such as pain, oedema, and problems with raising of the limb.

    Purpose Self-reported diabetes has been associated with poor breast cancer outcomes. Research is needed to investigate the relationship between biologically determined glycemic control and breast cancer prognosis. Methods Archived baseline blood samples from the Women's Healthy Eating and Living Study were used to measure hemoglobin A1C (HbA1C) among 3,003 survivors of early-stage breast cancer (age of diagnosis, 28 to 70 years) observed for a median of 7.3 years for additional breast cancer events and 10.3 years for all-cause mortality. HbA1C levels provide an accurate, precise measure of chronic glycemic levels. Cox regression analysis was performed to assess whether baseline HbA1C levels predicted disease-free and overall survival. Results Only 5.8% of women had chronic hyperglycemia (defined as HbA1C levels ≥ 6.5%). Those with HbA1C ≥ 6.5% were older and more likely to be less educated, have nonwhite ethnicity, be obese, and have more advanced breast cancer at diagnosis. HbA1C was significantly associated with overall survival (Ptrend < .001). After adjusting for confounders, risk of all-cause mortality was twice as high in women with HbA1C ≥ 7.0% compared with women with HbA1C less than 6.5% (hazard ratio [HR], 2.35; 95% CI, 1.56 to 3.54). For disease-free survival, there was a nonsignificant 30% increase in risk for HbA1C levels ≥ 7.0% (HR, 1.26; 95% CI, 0.78 to 2.02). During study follow-up, previously diagnosed rather than undiagnosed diabetes seemed to account for the increased risk. Conclusion Chronic hyperglycemia is statistically significantly associated with reduced overall survival in survivors of early-stage breast cancer. Further study of diabetes and its relationship to breast cancer outcomes is warranted. PMID:21115861

    Recent advances in primary and adjuvant treatment for early-stage breast cancer have reduced mortality rates, and improved the overall prognosis. Many patients can be cured, while others may survive for 10 years or more beyond diagnosis, thanks to a combination of preoperative therapy, surgery, radiotherapy, and systemic adjuvant therapy. Minimally invasive procedures, more effective drugs, and improved treatment regimens are helping to reduce breast cancer recurrences and deaths, while minimizing side effects and maintaining quality of life. Despite such improvements, a significant number of patients with early disease will relapse, including those who are clinically disease-free after primary and adjuvant therapy. Advances in breast tumor biology have led to the discovery of many different tumor types, and a uniform approach to treatment is no longer appropriate. Potential markers have been identified for the risk of relapse and responsiveness to a given therapy, thus treatment decisions and clinical guidelines, previously based on data from large patient populations, are changing to reflect a movement towards individually tailored treatment. Refinements in clinical practice will help physicians to identify the patients who will benefit the most from a particular approach, reducing overtreatment, and sparing patients unnecessary therapy. Genetic studies are helping to increase our understanding of the metastatic potential of tumors, leading to the development of adjuvant therapies for the prevention of metastases in selected patients. This article reviews the latest advances in treatment for early breast cancer, and explores how research and clinical practice are evolving to improve therapies and treatment decision-making, allowing physicians to optimize patient care.

    The purpose of this study was to assess the cardiac side effects, primarily the occurrence of ischemic heart disease, in symptom-free patients with early breast cancer treated with radiotherapy. Thirty-seven survivors of a former randomized study of early breast cancer were examined. Twenty patients irradiated pre- or postoperatively for left sided disease (study group patients) were compared with 17 controls who were either treated for right sided disease, or were nonirradiated patients. Radiotherapy was randomized in the original study; either tangential field [sup 60]Co, or electron-therapy was delivered. Echocardiography and bicycle ergometry stress test with [sup 99m]Tc SestaMIBI myocardial perfusion scintigraphy were carried out and the patients' major risk factors for ischemic heart disease were also listed. Our results showed a significant difference between the scintigraphic findings of the two groups. Five of the 20 study group patients (25%), while none of the 17 controls exhibited some kind of significant defects on scintigraphy, indicating ischemic heart disease (p < 0.05). No deterioration in left ventricular systolic and/or diastolic function could be detected by echocardiography. Radiotherapy for left sided breast cancer with the mentioned treatment technique may present as an independent risk factor in the long-term development of ischemic heart disease, while left ventricular dysfunction could not be related to the previous irradiation. The authors emphasize the need to optimize adjuvant radiotherapy for early breast cancer by considering the dose both to the heart as well as the cancer. 39 refs., 4 tabs.

    Genome-Wide Association Studies (GWAS) have begun to investigate associations between inherited genetic variations and breast cancer prognosis. Here, we report our findings from a GWAS conducted in 536 patients with early-onset breast cancer aged 40 or less at diagnosis and with a mean follow-up period of 4.1 years (SD = 1.96). Patients were selected from the Prospective Study of Outcomes in Sporadic versus Hereditary breast cancer. A Bonferroni correction for multiple testing determined that a P value of 1.0 × 10(-7) was a statistically significant association signal. Following quality control, we identified 487,496 single nucleotide polymorphisms (SNP) for association tests in stage 1. In stage 2, 35 SNPs with the most significant associations were genotyped in 1,516 independent cases from the same early-onset cohort. In stage 2, 11 SNPs remained associated in the same direction (P ≤ 0.05). Fixed effects meta-analysis models identified one SNP associated at close to genome wide level of significance 556 kb upstream of the ARRDC3 locus [HR = 1.61; 95% confidence interval (CI), 1.33-1.96; P = 9.5 × 10(-7)]. Four further associations at or close to the PBX1, RORα, NTN1, and SYT6 loci also came close to genome-wide significance levels (P = 10(-6)). In the first ever GWAS for the identification of SNPs associated with prognosis in patients with early-onset breast cancer, we report a SNP upstream of the ARRDC3 locus as potentially associated with prognosis (median follow-up time for genotypes: CC = 4 years, CT = 3 years, and TT = 2.7 years; Wilcoxon rank-sum test CC vs. CT, P = 4 × 10(-4) and CT vs. TT, P = 0.76). Four further loci may also be associated with prognosis.

    Recurrent breast cancer occurring after the initial treatment is associated with poor outcome. A bimodal relapse pattern after surgery for primary tumor has been described with peaks of early and late recurrence occurring at about 2 and 5 years, respectively. Although several clinical and pathological features have been used to discriminate between low- and high-risk patients, the identification of molecular biomarkers with prognostic value remains an unmet need in the current management of breast cancer. Using microarray-based technology, we have performed a microRNA expression analysis in 71 primary breast tumors from patients that either remained disease-free at 5 years post-surgery (group A) or developed early (group B) or late (group C) recurrence. Unsupervised hierarchical clustering of microRNA expression data segregated tumors in two groups, mainly corresponding to patients with early recurrence and those with no recurrence. Microarray data analysis and RT-qPCR validation led to the identification of a set of 5 microRNAs (the 5-miRNA signature) differentially expressed between these two groups: miR-149, miR-10a, miR-20b, miR-30a-3p and miR-342-5p. All five microRNAs were down-regulated in tumors from patients with early recurrence. We show here that the 5-miRNA signature defines a high-risk group of patients with shorter relapse-free survival and has predictive value to discriminate non-relapsing versus early-relapsing patients (AUC = 0.993, p-value<0.05). Network analysis based on miRNA-target interactions curated by public databases suggests that down-regulation of the 5-miRNA signature in the subset of early-relapsing tumors would result in an overall increased proliferative and angiogenic capacity. In summary, we have identified a set of recurrence-related microRNAs with potential prognostic value to identify patients who will likely develop metastasis early after primary breast surgery.

    Recurrent breast cancer occurring after the initial treatment is associated with poor outcome. A bimodal relapse pattern after surgery for primary tumor has been described with peaks of early and late recurrence occurring at about 2 and 5 years, respectively. Although several clinical and pathological features have been used to discriminate between low- and high-risk patients, the identification of molecular biomarkers with prognostic value remains an unmet need in the current management of breast cancer. Using microarray-based technology, we have performed a microRNA expression analysis in 71 primary breast tumors from patients that either remained disease-free at 5 years post-surgery (group A) or developed early (group B) or late (group C) recurrence.

All five microRNAs were down-regulated in tumors from patients with early recurrence. We show here that the 5-miRNA signature defines a high-risk group of patients with shorter relapse-free survival and has predictive value to discriminate non-relapsing versus early-relapsing patients (AUC = 0.993, p-value<0.05). Network analysis based on miRNA-target interactions curated by public databases suggests that down-regulation of the 5-miRNA signature in the subset of early-relapsing tumors would result in an overall increased proliferative and angiogenic capacity.

    Purpose: To report early outcomes of accelerated whole-breast radiation therapy with concomitant boost. Methods and Materials: This is a prospective, institutional review board-approved study. Eligibility included stage TisN0, T1N0, and T2N0 breast cancer. Patients receiving adjuvant chemotherapy were ineligible. The whole breast received 40.5 Gy in 2.7-Gy fractions with a concomitant lumpectomy boost of 4.5 Gy in 0.3-Gy fractions. Total dose to the lumpectomy site was 45 Gy in 15 fractions over 19 days. Results: Between October 2004 and December 2010, 160 patients were treated; stage distribution was as follows: TisN0, n=63; T1N0, n=88; and T2N0, n=9. With a median follow-up of 3.5 years (range, 1.5-7.8 years) the 5-year overall survival and disease-free survival rates were 90% (95% confidence interval [CI] 0.84-0.94) and 97% (95% CI 0.93-0.99), respectively. Five-year local relapse-free survival was 99% (95% CI 0.96-0.99). Acute National Cancer Institute/Common Toxicity Criteria grade 1 and 2 skin toxicity was observed in 70% and 5%, respectively. Among the patients with ≥2-year follow-up no toxicity higher than grade 2 on the Late Effects in Normal Tissues–Subjective, Objective, Management, and Analytic scale was observed. Review of the radiation therapy dose–volume histogram noted that ≥95% of the prescribed dose encompassed the lumpectomy target volume in >95% of plans. The median dose received by the heart D{sub 05} was 215 cGy, and median lung V{sub 20} was 7.6%. Conclusions: The prescribed accelerated schedule of whole-breast radiation therapy with concomitant boost can be administered, achieving acceptable dose distribution. With follow-up to date, the results are encouraging and suggest minimal side effects and excellent local control.

    In 1990, Congress passed the Breast and Cervical Cancer Mortality Prevention Act because of increases in the number of low-income and uninsured women being diagnosed with breast cancer. This act authorized the Centers for Disease Control and Prevention (CDC) to establish the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) to provide high-quality and timely breast and cervical cancer screening and diagnostic services to low-income, uninsured women. The program started in 1991, and, in 1993, Congress amended the act to allow the CDC to fund American Indian and Alaska Native tribes and tribal organizations. By 1996, the program was providing cancer screening across the United States. To ensure appropriate delivery and monitoring of services, the program adopted detailed policies on program management, evidence-based guidelines for clinical services, a systematized clinical data system to track service quality, and key partnerships that expand the program’s reach. The NBCCEDP currently funds 67 programs, including all 50 states, the District of Columbia, 5 US territories, and 11 tribes or tribal organizations. PMID:25099896

    This article deals with elderly Turkish women's experiences with breast self examination, clinical breast examination and mammography screening, as well as perceived barriers and facilitators in the theoretical framework of the Health Belief Model and the Health Promotion Model. This is a qualitative study performed on 46 elderly women aged 60-75 years. Data were collected with focus group interviews and analyzed systematically with qualitative analysis techniques to determine themes concerning knowledge and facilitators of and perceived barriers to early detection of breast cancer among elderly women. Barriers to screening were insufficient knowledge, fear, neglect/postponement, embarrassment/religious beliefs, inability to make an appointment, lack of a physician's recommendation and health professionals' attitudes. Facilitating factors were being informed about screening, fear, awareness of cancer screening, familial history of breast cancer and social support, making an appointment, health professionals' communication and physicians' recommendations. Public health nurses and health professionals from other health disciplines should be aware of elderly women's need for knowledge about screening, understand elderly women's fear and worries about their health and know barriers to and facilitators of screening.

    We investigated the hypothesis that patients developing high-grade erythema of the breast skin during radiation treatment could be more likely to present increased levels of proinflammatory cytokines which may lead, in turn, to associated fatigue. Forty women with early stage breast cancer who received adjuvant radiotherapy were enrolled from 2007 to 2010. Fatigue symptoms, erythema, and cytokine levels (IL-1β, IL-2, IL6, IL-8, TNF-α, and MCP-1) were registered at baseline, during treatment, and after radiotherapy completion. Seven (17.5%) patients presented fatigue without associated depression/anxiety. Grade ≥2 erythema was observed in 5 of these 7 patients. IL-1β, IL-2, IL-6, and TNF-α were statistically increased 4 weeks after radiotherapy (P < 0.05). After the Heckman two-step analysis, a statistically significant influence of skin erythema on proinflammatory markers increase (P = 0.00001) was recorded; in the second step, these blood markers showed a significant impact on fatigue (P = 0.026). A seeming increase of fatigue, erythema, and proinflammatory markers was observed between the fourth and the fifth week of treatment followed by a decrease after RT. There were no significant effects of hormone therapy, breast volume, and anemia on fatigue. Our study seems to suggest that fatigue is related to high-grade breast skin erythema during radiotherapy through the increase of cytokines levels. PMID:24800238

  6. Anastrozole Use in Early Stage Breast Cancer of Post-Menopausal Women

    2009-01-01

    Summary The majority of breast cancers express the estrogen receptor and depend on estradiol (E2) for their growth. Hormonal therapy aims at depriving estrogen signaling either by using selective estrogen receptor modulators (SERM)—that interfere with the binding of E2 to its receptor (ER)—or aromatase inhibitors (AI)—that block the aromatase-dependent synthesis of E2. While SERMs are recommended for both pre- and post-menopausal patients, AIs are indicated only for post-menopausal patients. For the past 20 years, the SERM tamoxifen has been considered the “gold standard” for the treatment of hormone receptor positive breast cancers. However, tamoxifen’s role is now challenged by third generation AIs, such as anastrozole, which exhibit greater efficacy in the adjuvant setting in several recently reported trials. This review will focus on anastrozole’s mechanism of action, dosing, pharmacology, pharmacokinetics, and clinical applications. It will briefly discuss the clinical trials that determined anastrozole’s efficacy in the treatment of advanced breast cancer (ABC) and in the neoadjuvant setting. Finally, it will present the clinical trials that established anastrozole as a frontline agent in the treatment of post-menopausal women with hormone receptor positive early breast cancer.

    Although breast cancer remains a major cause of cancer death, its related death rate has dropped in the last years through early tumor detection and better available treatments. With the development of innovative techniques and new molecules as well as new routes of administration, local treatment and adjuvant therapy of early breast cancer have evolved, from mutilating, time-consuming and/or painful procedures to breast-conservative ones, sparing healthy tissues, reducing the total dose of treatment and the treatment time which in turn reduce the occurrence and severity of toxicity. In parallel with these improvements leading to an increase in survival rate, patients' health-related quality of life has become a major concern. This review aims at describing the evolution of early breast cancer treatment, and its impact on patients' quality of life, convenience, and satisfaction, including a special insight into emerging human epidermal growth factor receptor 2 (HER2)-targeted therapy.

  10. The Management of Early Stage and Metastatic Triple Negative Breast Cancer: A Review

    2013-01-01

    Triple negative breast cancer (TNBC) defined as lacking expression of the estrogen receptor, progesterone receptor and HER2, comprises approximately 15% of incident breast cancers and is over-represented among those with metastatic disease. It is increasingly clear that TNBC is heterogeneous and that there are several biologically distinct subtypes within TNBC, in particular the basal-like subtype but also the claudin-low, among others. While the incidence of BRCA mutations across all subsets of breast cancer is quite low (~5%), BRCA mutations are more common among those with TNBC (~20%) and may have therapeutic implications. The general principles guiding the use of chemotherapy and radiation therapy do not differ dramatically between early stage TNBC and non-TNBC. There is a trend, however, to treat TNBC at a lower stage with chemotherapy as this is the only way to systemically reduce recurrence risk. In the metastatic setting, while cytotoxic chemotherapy is the mainstay of treatment for advanced TNBC, there are many promising targeted therapies in development in both the preclinical and early phase clinical trial settings. While the treatment of TNBC remains a challenge, coordinated efforts between clinician/scientist partnerships providing a comprehensive understanding of TNBC genomic, proteomic and other biologic processes may result in individualized therapy for TNBC faster than other subtypes -- driven by both the heterogeneity we know exists within this clinical entity and the intense need for improved treatment.

    The impact of breast milk feeding on susceptibility to asthma in childhood is highly controversial, due in part to failure of the majority of studies in the area to adequately account for key confounders exemplified by respiratory infection history, plus the effects of recall bias. As part of a prospective cohort study on the role of respiratory infections in asthma development in high-risk children, we measured the concentration of a panel of anti-infective proteins in maternal milk samples and analyzed associations between these and subsequent atopy-, infection-, and asthma-related outcomes prospectively to age 10 years. We observed significant but transient inverse associations between the concentration of milk proteins and susceptibility to upper respiratory infections in year 1 only, and parallel but positive transient associations with early lower respiratory infections and atopy. No associations were seen with asthma-related outcomes. Breast milk feeding may influence the expression of inflammatory symptoms associated with respiratory infections and atopy in early life, but these effects appear to be inconsistent and transient. The heterogeneous nature of breast-feeding effects suggests it may influence systemic immunoinflammatory function at several different levels. © 2014 John Wiley & Sons A/S.

    Eighty-five female patients with early stage breast cancer, i.e., Stage I and II were treated by limited surgery followed by radical radiation therapy at Massachusetts General Hospital between January, 1956 and December, 1974. Patients included those who were medically inoperable or who refused mastectomy. The 5-year survival rate was 83% and 76% for Stage I and II, respectively. The corresponding disease free survival (absolute) was 67% and 42%. Although the number of patients so treated is small, there was no significant difference in survival from the results of the radical mastectomy series at the same institution. No major complications were encountered. Seventeen of eighty-five patients developed minor problems; mostly fibrosis and minimal arm lymphedema stemmming from older orthovoltage equipment and treatment techniques. With the current availability of megavoltage equipment, improvements in techniques and dosimetry, complications should decrease. Combined limited surgery and radical radiation therapy should be considered in those patients where a radical mastectomy is not feasible because of psychological or medical problems. Since this procedure results in a cosmetically acceptable breast, radical radiation in early stage breast cancer seems a reasonable alternative to radical mastectomy.

    Tamoxifen is currently the standard of care for premenopausal women with hormone receptor-positive early breast cancers. However, endocrine strategies in premenopausal women include not only estrogen receptor blockade with tamoxifen but also temporary suppression of ovarian estrogen synthesis by luteinizing hormone-releasing hormone (LHRH) agonists, or permanent interruption of ovarian estrogen synthesis with oophorectomy or radiotherapy. Luteinizing hormone-releasing hormone agonists have proven to be as effective as surgical oophorectomy in adjuvant treatment of premenopausal breast cancer. The addition of LHRH agonists compared to no therapy reduces the annual odds of recurrence and death in premenopausal women aged less than 50 years with estrogen receptor-positive tumors. Luteinizing hormone-releasing hormone agonists alone or in combination with tamoxifen have shown disease-free survival rates similar to chemotherapy with CMF (cyclophosphamide/methotrexate/5-fluorouracil) and other second-generation chemotherapies. The role of aromatase inhibitors in combination with ovarian suppression is still not established, especially as a large phase III randomized study (Austrian Breast and Colorectal Cancer Study Group Trial 12) did not show superior efficacy compared with ovarian suppression plus tamoxifen in premenopausal early stage disease. Patients currently continue to receive ovarian suppression and tamoxifen. CYP2D6 status may become an important discriminator for the type of endocrine therapy for the premenopausal patient in the future.

    The current report provides the result of a Phase II clinical trial regarding the effectiveness and feasibility of problem-solving therapy for psychological distress experienced by Japanese early-stage breast cancer patients. Participants were 36 post-surgery Japanese breast cancer patients in a university hospital located in Osaka Prefecture, Japan. After screening for psychological distress using the Distress and Impact Thermometer and the Hospital Anxiety and Depression Scale, highly distressed patients were exposed to 5 weekly sessions of the problem-solving therapy program. Nineteen patients completed the intervention and follow-up. There was a significant difference between the pre-intervention and the 3-month follow-up in the total Hospital Anxiety and Depression Scale score (P = 0.02), and the mean change score from the pre-intervention to the follow-up was 6.05 (SD = 1.94). The intervention had a large effect size (d = 0.82). There were also significant changes in worry, self-efficacy and quality of life measures. The findings of our study suggest that the problem-solving therapy program has potential to be effective for alleviating psychological distress experienced by Japanese early-stage breast cancer patients. The true effectiveness of the program should be confirmed by a future randomized control trial.

    Background: Increasing numbers of patients with early cancer undergo routine staging using computerized tomography (CT). Those in whom indeterminate pulmonary nodules are visualized without the presence of other metastatic lesions represent a clinical dilemma regarding their management as early breast cancer or metastatic disease. Patients and methods: Medical records of breast cancer patients who underwent thoracic CT scans between the years 2002 and 2008 were analyzed. Those with obvious metastatic disease were excluded. Patients were identified via the radiology database by searching for the terms: ‘suspicious lung metastases’ and ‘indeterminate nodules’. Results: Out of 1578 new patients assessed from 2002 to 2008, we carried out 802 staging CT scans. Thirty-four cases (4.2%) with indeterminate pulmonary nodules were identified. We categorized cases by size and number of nodules. At a median follow-up of 18 months, there were no changes in lesion size in 86% of patients with a solitary nodule <1 cm and 89% with multiple subcentimeter nodules. In contrast, in 100% of cases with pulmonary nodules >1 cm, the nodules had progressed at follow-up (χ2, P = 0.004). Conclusions: Breast cancer cases with subcentimeter indeterminate pulmonary lesions and no evidence of metastases elsewhere are unlikely to represent metastatic disease. Treatment with curative intent or entry into clinical trials should not be excluded. PMID:18641008

    To describe the social representation that adolescents from Jalisco, Mexico, have of early detection of breast cancer. Qualitative cross, analytical interpretative and based on the theory of social representations. Non-probability sampling. Contact schools in basic education level of 7municipalities of the State of Jalisco, Mexico, through various government and educational institutions. A hundred thirty five schooled adolescents, men and women. Interview with 12 focus group 8-12participants and 1 with 18participants. The interviews were transcribed in Atlas Ti program version 4.1 for a semiotic analysis to identify components of social representation. The precocious detection linked itself to the decrease of deaths for cancer of breast, long treatments and mastectomy, but little coverage was perceived to the mammary health of the teenager. They refer as limiter elements of the precocious detection the aspects of kind, psychological and of access to the information and services of health; since facilitators there was mentioned the transition of the limiter elements to facilitators. A favorable panorama appears on the level of awareness of the teenagers on his mammary health, identifying as a sector highly sensitive to the information about cancer of breast and with disposition to effect actions of early detection; there are identified as important challenge the generation of campaigns, educational materials and spaces of health focused on the teenager.

    The purpose was to construct a decision model that incorporated patient preferences over differing health state prospects and to analyze the decision context of early stage breast cancer patients in relation to two main surgical treatment options. A Markov chain was constructed to project the clinical history of breast carcinoma following surgery. A Multi Attribute Utility Model was developed for outcome evaluation. Transition probabilities were obtained by using subjective probability assessment. This study was performed on the sample population of female university students and utilities were elicited from these healthy volunteers. The results were validated by using Standard Gamble technique. Finally, Monte Carlo Simulation was utilized in Treeage-Pro 2006-Suit software program in order to calculate expected utility generated by each treatment option. The results showed that, if the subject had mastectomy, mean value for the quality adjusted life years gained was 6.42; on the other hand, if the preference was lumpectomy, it was 7.00 out of a possible 10 years. Sensitivity analysis on transition probabilities to local recurrence and salvaged states was performed and two threshold values were observed. Additionally, sensitivity analysis on utilities showed that the model was more sensitive to no evidence of disease state; however, was not sensitive to utilities of local recurrence and salvaged states. The decision model was developed with reasonable success for early stage breast cancer patients, and tested by using general public data. The results obtained from these data showed that lumpectomy was more favourable for these participants.

    Conventional preoperative chemotherapy regimens have only limited efficacy in hormone receptor positive (HR+) breast cancer and new approaches are needed. We hypothesized that capecitabine, which is effective in metastatic breast cancer, may be an active preoperative treatment for HR+ breast cancer. Women with HR+, HER2-negative operable breast cancer received capecitabine, 2000 mg/m2 daily in divided doses for 14 days, followed by a 7-day rest period. Treatment was repeated every 21 days for a total of four cycles. The primary endpoint of the study was to determine the rate of pathological complete response (pCR). Because of slow accrual, the study was closed after 24 patients were enrolled. Three patients had a complete clinical response, and eight patients had a partial clinical response, for an overall clinical response rate of 45.8%. There were no cases of pCR. Of the 22 patients who had pathological response assessment by the Miller–Payne grading system, there were six grade 3 responses, and no grade 4 or 5 responses. Toxicity was manageable: the only grade 3 toxicities observed were one case each of diarrhea, palmar plantar erythrodysesthesia, hypokalemia, and mucositis. There was no association between baseline levels, or change in level from baseline to cycle 1, or from baseline to time of surgery, of thymidine phosphorylase (TYMP), thymidylate synthase (TYMS), dihydropyrimidine dehydrogenase (DPYD), or Ki67 and pathological, clinical, or radiographic response. Preoperative capecitabine is a well-tolerated regimen, but appears not lead to pCR when used as monotherapy in HR+ breast cancer. PMID:24464780

    Only a few papers have been published concerning the incidence and outcome of patients with a pathological complete response after cytotoxic treatment in breast cancer. The purpose of this retrospective study was to assess the outcome of patients found to have a pathological complete response in both the breast and axillary lymph nodes after neoadjuvant chemotherapy for operable breast cancer. Our goal was also to determine whether the residual pathological size of the tumour in breast could be correlated with pathological node status. Between 1982 and 2000, 451 consecutive patients were registered into five prospective phase II trials. After six cycles, 396 patients underwent surgery with axillary dissection for 277 patients (69.9%). Pathological response was evaluated according to the Chevallier's classification. At a median follow-up of 8 years, survival was analysed as a function of pathological response. A pathological complete response rate was obtained in 60 patients (15.2%) after induction chemotherapy. Breast tumour persistence was significantly related to positive axillary nodes (P=5.10−6). At 15 years, overall survival and disease-free survival rates were significantly higher in the group who had a pathological complete response than in the group who had less than a pathological complete response (P=0.047 and P=0.024, respectively). In the absence of pathological complete response and furthermore when there is a notable remaining pathological disease, axillary dissection is still important to determine a major prognostic factor and subsequently, a second non cross resistant adjuvant regimen or high dose chemotherapy could lead to a survival benefit.

    We assessed income tax check-offs, specialty license plates, and lottery tickets as ways states raise funds for the early detection and prevention of breast cancer. We conducted an inventory of state legislation allowing these revenue-generating methods, and collected and compared information on each initiative. We conducted logistic regression analyses to compare these methods with state breast cancer mortality rates. Eighteen states had programs for contributions through an income tax check-off. Revenue for tax check-offs and plates is influenced by state population. The median annual revenue for the income tax check-off was $115,000. Twenty-six states had breast cancer license plates generating more than $4.1 million in revenue. The extra cost of the plates ranged from $20 to 75 (mean = $37). Only Illinois offered a state breast cancer lottery ticket, which raised $4 million from 2005 to 2009. States with medium or high breast cancer mortality rates were 2.5 times more likely to offer breast cancer specialty license plates than states with low breast cancer mortality rates; however, we found no statistically significant difference in breast cancer mortality tertiles by income tax check-off. Revenue-generating breast cancer initiatives can be successful strategies for states to raise funds for breast cancer prevention and early detection programs. Although these initiatives can generate revenue, amounts are variable due to population differences, the number of other plates/check-offs/lotteries offered, and the choice to decrease donations during difficult economic times. State breast cancer mortality rates may influence the availability of these initiatives.

    Although approximately 57% of breast cancer (BC) diagnoses are in older patients (>60 years), only 4.1-14% receives breast reconstruction (BR). This has been attributed to physician concerns about operative complications. This paper aims to: 1) analyze the 30-day complication rates in the older patient population undergoing immediate breast reconstruction (IBR); and 2) analyze links between complication type and category of reconstruction. Using the ACS-NSQIP database (2005-2014), all women older than 60 years of age diagnosed with BC and DCIS were identified. IBR and complication rates were plotted for all ages. Patients were divided into those with and those without complications. Patient demographics and co-morbidities were compared. Complications within each type of reconstruction were analyzed. Of the 4450 BC and 1104 DCIS patients, 22.3% (BC) and 20.9% (DCIS) had complications. IBR decreased significantly with increased age (P < 0.00 in both cohorts), while complication rates remained stable across all ages (P = 0.32 in BC, P = 0.69 in DCIS patients). Patients were well matched in terms of demographics. The rates of breast reconstruction decrease with increasing age. Despite increasing age, associated complication rates in IBR patients remained stable. © 2017 Wiley Periodicals, Inc.

For the treatment of HER2-positive disease in patients with node-negative cancers up to 1 cm, the Panel endorsed a simplified regimen comprising paclitaxel and trastuzumab without anthracycline as adjuvant therapy. For premenopausal patients with endocrine responsive disease, the Panel endorsed the role of ovarian function suppression with either tamoxifen or exemestane for patients at higher risk. The Panel noted the value of an LHRH agonist given during chemotherapy for premenopausal women with ER-negative disease in protecting against premature ovarian failure and preserving fertility. The Panel noted increasing evidence for the prognostic value of commonly used multiparameter molecular markers, some of which also carried prognostic information for late relapse. The Panel noted that the results of such tests, where available, were frequently used to assist decisions about the inclusion of cytotoxic chemotherapy in the treatment of patients with luminal disease, but noted that threshold values had not been established for this purpose for any of these tests.

    Li-Fraumeni syndrome (LFS) is one of the most penetrant forms of familial cancer susceptibility syndromes, characterized by early age at tumor onset and a wide spectrum of malignant tumors. Identifying LFS in patients with cancer is clinically imperative because they have an increased sensitivity to ionizing radiation and are more likely to develop radiation-induced secondary malignancies. This case report describes a young woman whose initial presentation of LFS was early-onset breast cancer and whose treatment of this primary malignancy with breast conservation likely resulted in a secondary malignancy arising in her radiation field. As seen in this case, most breast cancers in patients with LFS exhibit a triple-positive phenotype (estrogen receptor-positive/progesterone receptor-positive/HER2-positive). Although this patient met classic LFS criteria based on age and personal and family history of cancer, the NCCN Clinical Practice Guidelines in Oncology for Genetic/Familial High-Risk Assessment: Breast and Ovarian Cancer endorse genetic screening for TP53 mutations in a subset of patients with early-onset breast cancer, even in the absence of a suggestive family history, because of the potential for de novo TP53 mutations.

    Parents of children with autism spectrum disorders (ASDs) often report gastrointestinal (GI) dysfunction in their children. The objectives of the present study were to determine whether infants at high risk for developing ASD (ie, siblings of children diagnosed as having ASD) show greater prevalence of GI problems and whether this prevalence is associated with diet and age at weaning from breast milk. Using questionnaires, diet history and GI problems were tracked prospectively and retrospectively in 57 high-risk infants and for comparison in 114 low-risk infants (infants from families without ASD history). In low-risk infants, prevalence of GI symptoms, in aggregate, did not vary with diet or age of weaning. By contrast, high-risk infants with GI symptoms were weaned earlier than those without symptoms (P < 0.04), and high-risk infants showed greater prevalence of GI symptoms, in aggregate, on a no breast milk diet than on an exclusive breast milk diet (P < 0.017). Constipation, in particular, was more prevalent in high-risk infants compared with low-risk infants (P = 0.01), especially on a no breast milk diet (P = 0.002). High-risk infants who completed weaning earlier than 6 months showed greater prevalence of constipation (P = 0.001) and abdominal distress (P = 0.004) than those fully weaned after 6 months. The greater prevalence of GI symptoms in high-risk infants suggests that GI dysfunction during early infant development may be a part of the ASD endophenotype. Late weaning and exclusive breast milk were associated with protection against GI symptoms in high-risk infants.

    Purpose: The optimal sequencing of adjuvant chemotherapy (CT) and radiation therapy (RT) in patients with early-stage breast cancer remains unclear. Patients and Methods: We retrospectively compared 485 patients treated with conservative breast surgery and postoperative whole-breast RT and six courses of CMF (cyclophosphamide 600 mg/m{sup 2}, methotrexate 40 mg/m{sup 2}, and 5-fluorouracil 600 mg/m{sup 2}) with 300 patients who received postoperative CMF only and with 509 patients treated with postoperative whole-breast RT only. The mean radiation dose delivered was 50 Gy (range, 46-52 Gy) with standard fractionation. The boost dose was 6-16 Gy according to resection margins and at the discretion of the radiation oncologist. Acute and late RT toxicity were scored using respectively the Radiation Therapy Oncology Group and the Late Effects in Normal Tissues Subjective, Objective, Management and Analytic scale. Results: A slightly higher Grade 2 acute skin toxicity was recorded in the concurrent group (21.2% vs. 11.2% of the RT only group, p < 0.0001). RT was interrupted more frequently in the CMF/RT group respective to the RT group (8.5% vs. 4.1%; p = 0.006). There was no difference in late toxicity between the two groups. All patients in the concurrent group successfully received the planned dose of RT and CT. Local recurrence rate was 7.6% in CT/RT group and 9.8% in RT group; this difference was not statistically significant at univariate analysis (log-rank test p = 0.98). However, at multivariate analysis adjusted also for pathological tumor, pathological nodes, and age, the CT/RT group showed a statistically lower rate of local recurrence (p = 0.04). Conclusions: Whole-breast RT and concurrent CMF are a safe adjuvant treatment in terms of toxicity.

    Purpose Genomic Grade Index (GGI) is a 97-gene signature that improves histologic grade (HG) classification in invasive breast carcinoma. In this prospective study we sought to evaluate the feasibility of performing GGI in routine clinical practice and its impact on treatment recommendations. Methods Patients with pT1pT2 or operable pT3, N0-3 invasive breast carcinoma were recruited from 8 centers in Belgium. Fresh surgical samples were sent at room temperature in the MapQuant Dx™ PathKit for centralized genomic analysis. Genomic profiles were determined using Affymetrix U133 Plus 2.0 and GGI calculated using the MapQuant Dx® protocol, which defines tumors as low or high Genomic Grade (GG-1 and GG-3 respectively). Results 180 pts were recruited and 155 were eligible. The MapQuant test was performed in 142 cases and GGI was obtained in 78% of cases (n=111). Reasons for failures were 15 samples with <30% of invasive tumor cells (11%), 15 with insufficient RNA quality (10%), and 1 failed hybridization (<1%). For tumors with an available representative sample (≥ 30% inv. tumor cells) (n=127), the success rate was 87.5%. GGI reclassified 69% of the 54 HG2 tumors as GG-1 (54%) or GG-3 (46%). Changes in treatment recommendations occurred mainly in the subset of HG2 tumors reclassified into GG-3, with increased use of chemotherapy in this subset. Conclusion The use of GGI is feasible in routine clinical practice and impacts treatment decisions in early-stage breast cancer.

    The project SafeLand is intended to develop generic risk management tools and strategies for landslides. Indeed, the intention of the screening study is to provide guidelines that will help and facilitate the establishment of new early warning systems (EWS) and to increase the quality of existing systems (Bazin et al., 2012). Consequently, one of the first steps is to merge actual knowledge and expert judgments. Thus, as part of this study, we gathered experiences from organizations in charge of landslide EWSs and risk management in order to compile information about the state of the art technologies and existing strategies. To ensure those objectives, a questionnaire was produced by UNIL, ICG and ÅTB. Divided in 5 parts, the questionnaires collected information about: 1. General information on the unit in charge of the EWS; 2. Knowledge about the monitored landslide; 3. Pre-investigations used to design the EWS; 4. Monitoring parameters, thresholds and sensors evaluation; 5. Warnings, communications and decision making process. Finally, sent in June 2011 to about hundred organizations in charge of one or several EWS, 14 institutions from 8 countries sent the questionnaires back during the summer and autumn 2011, speaking about 23 landslides. The compilation and analysis of the most interesting answers are the scope of this poster. First, there are no common requirements to design and operate EWSs. From the surveyed countries, only Norway and Slovakia have produced codes or recommendations for this purpose. Secondly, more than 81% of the EWSs are based on displacement monitoring, certainly because it is the direct evidence of deformations. Then the weather conditions are monitored for more than half of the cases. It is also an essential parameter since rainfalls are a destabilizing factor for more than 80% of the studied landslides. Then, advantages and limitations of existing EWSs are clearly defined. Indeed, an EWS should be (1) robust, (2) simple, (3) redundant

    Toremifene, a selective estrogen receptor modulator, is used as adjuvant therapy for postmenopausal patients with breast cancer in Japan. For Japanese patients, however, only limited data are available on the efficacy and safety profile of toremifene. To establish the long term efficacy and safety of toremifene for Japanese patients, we conducted a prospective, multicenter, randomized phase III trial comparing toremifene and tamoxifen. The subjects were postmenopausal Japanese patients who had undergone surgery for node-negative breast cancer. Toremifene or tamoxifen was administered for 2 years. The primary endpoint was demonstration of the non-inferiority of toremifene compared with tamoxifen in respect of 5-year survival. Secondary endpoints were cumulative overall survival, cumulative disease-free survival, effects on lipid profiles, and adverse events. A total of 253 patients were enrolled. The baseline characteristics of the two treatment groups were well-balanced. Median follow-up was 66.5 months. Five-year survival was similar for toremifene and tamoxifen (97.0 vs. 96.9 %; 90 % confidence interval -3.9 to 4.1), indicating that toremifene is not inferior to tamoxifen for postmenopausal Japanese patients with early breast cancer. Cumulative overall survival and cumulative disease-free survival were also very similar for toremifene and tamoxifen (97.5 vs. 97.3 %, log-rank test P = 0.9458; 88.4 vs. 90.6 %, log-rank test P = 0.3359, respectively). Adverse events in both groups were similar and mostly mild or moderate. Thus, both are equally effective and well tolerated. Our results suggest that the efficacy and safety of toremifene and tamoxifen are equivalent for postmenopausal Japanese patients with early breast cancer.

    To identify the information older women with early-stage breast cancer need when making radiation therapy decisions, and who patients identify as the main decision maker. We surveyed (through face-to-face interview, telephone, or mail) women aged ≥65 years who received lumpectomy and were considering or receiving adjuvant radiation therapy for early-stage breast cancer. The survey instrument was constructed with input from patient and professional advisory committees, including breast cancer survivors, advocates of breast cancer care and aging, clinicians, and researchers. Participants rated the importance (on a 4-point scale) of 24 statements describing the benefits, side effects, impact on daily life, and other issues of radiation therapy in relation to radiation therapy decision making. Participants also designated who was considered the key decision maker. The response rate was 56.4% (93 of 165). Mean age was 72.5 years, ranging from 65 to 93 years. More than 96% of participants indicated they were the main decision maker on receiving radiation therapy. There was wide variation in information needs regarding radiation therapy decision making. Participants rated a mean of 18 (range, 3-24) items as "essential." Participants rated items related to benefits highest, followed by side effects. Participants who were older than 75 years rated 13.9 questions as essential, whereas participants aged ≤74 years rated 18.7 as essential (P=.018). Older women desire information and have more agency and input in the decision-making process than prior literature would suggest. The variation in information needs indicates that future decision support tools should provide options to select what information would be of interest to the participants.

    To conduct a pragmatic randomised controlled trial (RCT) to evaluate the effects of reflexology on quality of life (QofL) in women with early breast cancer. One hundred and eighty-three women were randomised 6 weeks post-breast surgery to self-initiated support (SIS) (comparator intervention), SIS plus reflexology, or SIS plus scalp massage (control for physical and social contact). Reflexology and massage comprised eight sessions at weekly intervals. The primary end-point was 18 weeks post surgery; the primary outcome measure was the Trial Outcome Index (TOI) of the Functional Assessment of Cancer Therapy (FACT-B) - breast cancer version. The secondary end-point was 24 weeks post surgery. Secondary outcome measures were the Hospital Anxiety and Depression Scale (HADS) and the Mood Rating Scale (MRS). At primary end-point, massage, but not reflexology, was significantly better than SIS on the TOI. Reflexology and massage were both better than SIS for MRS relaxation. Massage was better than reflexology and SIS for MRS easygoingness. At secondary end-point, reflexology, but not massage, was better than SIS on the TOI and MRS relaxation. There were no significant differences between reflexology or massage. There were no significant between group differences in HADS anxiety and depression. Self-reported use of out of study complementary therapies indicated that this was unlikely to have a significant effect on findings. When compared to SIS, reflexology and massage have statistically significant, and, for reflexology, clinically worthwhile, effects on QofL following surgery for early breast carcinoma.

    In the last decades, there have been no studies carried out in Lithuania on the quality of life of breast cancer patients. The aim of the present study was to evaluate changes in the quality of life of Lithuanian women with the early stage of breast cancer nine months after surgery and its dependence on surgical strategy, adjuvant chemotherapy and the social and demographic status of the patients. Seventy-seven patients with early stage breast cancer filled in the FACT-An questionnaire twice: one week and nine months after the surgery. The main age of the patients was 53.1 +/- 10.6 years. We distinguished the mastectomy group and breast conserving treatment (BCT) group with/without chemotherapy. The groups were identical in their social and demographic status (age, education, occupation and marital status). Changes in the quality of life in these groups were compared nine months after surgery. Nine months after surgery, the overall quality of life was found worse in both mastectomy and BCT groups. Changes were induced by the worsening of the emotional and social well-being. The quality of life became worse in the mastectomy plus chemotherapy sample. No changes were detected in the mastectomy group without chemotherapy. In addition, the multivariate analysis showed that the marital status was quite a significant determinant of the functional well-being. Nine months after surgery, the study revealed a worsening of the overall quality of life in both groups of patients--those who had undergone mastectomy and BCT. The quality of life became considerably worse in the mastectomy plus chemotherapy group. Marital status was found to exert the most considerable influence on the women's quality of life in comparison with other social and demographic factors.

    Purpose: In young women, breast-conserving therapy (BCT), i.e., lumpectomy followed by radiotherapy, has been associated with an increased risk of local recurrence. Still, there is insufficient evidence that BCT impairs survival. The aim of our study was to compare the effect of BCT with mastectomy on overall survival (OS) in young women with early-stage breast cancer. Methods and Materials: From two Dutch regional population-based cancer registries (covering 6.2 million inhabitants) 1,453 women <40 years with pathologically T1N0-1M0 breast cancer were selected. Cox regression survival analysis was used to study the effect of local treatment (BCT vs. mastectomy) stratified for nodal stage on survival and corrected for tumor size, age, period of diagnosis, and use of adjuvant systemic therapy. Results: With a median follow-up of 9.6 years, 10-year OS was 83% after BCT and 78% after mastectomy, respectively (unadjusted hazard ratio [HR], 1.37; 95% confidence interval [CI], 1.09-1.72). In N0-patients, 10-year OS was 84% after BCT and 81% after mastectomy and local treatment was not associated with differences in OS (HR 1.19; 95% CI, 0.89-1.58; p = 0.25). Within the N1-patient group, OS was better after BCT compared with mastectomy, 79% vs. 71% at 10 years (HR 1.91; 95% CI, 1.28-2.84; p = 0.001) and in patients treated with adjuvant hormonal therapy (HR 0.34; 95% CI, 0.18-0.66; p = 0.001). Conclusions: In this large population-based cohort of early-stage young breast cancer patients, 10-year OS was not impaired after BCT compared with mastectomy. Patients with 1 to 3 positive lymph nodes had better prognosis after BCT than after mastectomy.

    Several clinical studies analyze axillary treatment in women with early-stage breast cancer because of changes in the indication for axillary lymph node dissection. The aim of the study is to analyze the impact of axillary radiotherapy in disease-free and overall survival in women with early breast cancer treated with lumpectomy. Retrospective study in women with initial stages of breast carcinoma treated by lumpectomy. A comparative analysis of high-risk women with axillary lymph node involvement who received axillary radiotherapy with the group of women with low risk without radiotherapy was performed. Logistic regression was used to determine factors influencing survival and lymphedema onset. A total of 541 women were included in the study: 384 patients (71%) without axillary lymph node involvement and 157 women (29%) with 1-3 axillary lymph node involvement. Patients with axillary radiotherapy had a higher number of metastatic lymph node compared to non-irradiated (1.6±0.7 vs. 1.4±0.6, P=.02). The group of women with axillary lymph node involvement and radiotherapy showed an overall and disease-free survival at 10 years similar to that obtained in patients without irradiation (89.7% and 77.2%, respectively). 3 lymph nodes involved multiplied by more than 7 times the risk of death (HR=7.20; 95% CI: 1.36 to 38.12). The multivariate analysis showed axillary lymph node dissection as the only variable associated with the development of lymphedema. The incidence of axillary relapse on stage I and II breast cancer is rare. In these patients axillary radiotherapy does not improve overall survival, but contributes to regional control in those patients with risk factors. Copyright © 2016 AEC.

A dosimetric and radiobiological perspective will help point out the evolution in breast brachytherapy, both in terms of devices and the protocols/clinical trials under which these devices are used. Improvements in imaging, delivery modalities and convenience are among the factors driving the ultrashort fractionation schedules but our understanding of both local control and toxicities associated with various treatments is lagging. A comparison between various schedules, from a radiobiological perspective, will be given together with a critical analysis of the issues. to review and understand the evolution and development of APBI using brachytherapy methods to understand the basis and limitations of radio-biological ‘equivalence’ between fractionation schedules to review commonly used and proposed fractionation schedules Intra-operative breast brachytherapy: Is one stop shopping best?- Bruce Libby, PhD.

    Purpose: To report a phase 2 trial of accelerated, hypofractionated whole-breast irradiation (AH-WBI) delivered as a daily dose of 3 Gy to the whole breast followed by a tumor bed boost. Methods and Materials: Two hundred seventy-six patients diagnosed with breast cancer (pT1-2 and pN0-1a) who had undergone breast-conserving surgery in which the operative margins were negative were treated with AH-WBI delivered as 39 Gy in 13 fractions of 3 Gy to the whole breast once daily over 5 consecutive working days, and 9 Gy in 3 sequential fractions of 3 Gy to a lumpectomy cavity, all within 3.2 weeks. Results: After a median follow-up period of 57 months (range: 27-75 months), the rate of 5-year locoregional recurrence was 1.4% (n=4), whereas that of disease-free survival was 97.4%. No grade 3 skin toxicity was reported during the follow-up period. Qualitative physician cosmetic assessments of good or excellent were noted in 82% of the patients at 2 months after the completion of AH-WBI. The global cosmetic outcome did not worsen over time, and a good or excellent cosmetic outcome was reported in 82% of the patients at 3 years. The mean pretreatment percentage breast retraction assessment was 12.00 (95% confidence interval [CI]: 11.14-12.86). The mean value of percentage breast retraction assessment increased to 13.99 (95% CI: 12.17-15.96) after 1 year and decreased to 13.54 (95% CI: 11.84-15.46) after 3 years but was not significant (P>.05). Conclusions: AH-WBI consisting of 39 Gy in 13 fractions followed by a tumor bed boost sequentially delivering 9 Gy in 3 fractions can be delivered with excellent disease control and tolerable skin toxicity in patients with early-stage breast cancer after breast-conserving surgery.

    Moment magnitudes for large earthquakes (Mw≥7.0) derived in real time from near-field seismic data can be underestimated due to instrument limitations, ground tilting, and saturation of frequency/amplitude-magnitude relationships. Real-time high-rate GPS resolves the buildup of static surface displacements with the S wave arrival (assuming nonsupershear rupture), thus enabling the estimation of slip on a finite fault and the event's geodetic moment. Recently, a range of high-rate GPS strategies have been demonstrated on off-line data. Here we present the first operational system for real-time GPS-enhanced earthquake early warning as implemented at the Berkeley Seismological Laboratory (BSL) and currently analyzing real-time data for Northern California. The BSL generates real-time position estimates operationally using data from 62 GPS stations in Northern California. A fully triangulated network defines 170+ station pairs processed with the software trackRT. The BSL uses G-larmS, the Geodetic Alarm System, to analyze these positioning time series and determine static offsets and preevent quality parameters. G-larmS derives and broadcasts finite fault and magnitude information through least-squares inversion of the static offsets for slip based on a priori fault orientation and location information. This system tightly integrates seismic alarm systems (CISN-ShakeAlert, ElarmS-2) as it uses their P wave detections to trigger its processing; quality control runs continuously. We use a synthetic Hayward Fault earthquake scenario on real-time streams to demonstrate recovery of slip and magnitude. Reanalysis of the Mw7.2 El Mayor-Cucapah earthquake tests the impact of dynamic motions on offset estimation. Using these test cases, we explore sensitivities to disturbances of a priori constraints (origin time, location, and fault strike/dip).

    Young women, high school age, are exposed to breast cancer messages targeting adult women that can result in misperceptions, increasing future risks. Changes in breast self-exam screening recommendations may reduce nurse practitioner (NP) time addressing breast health. This study characterized misperceived knowledge of breast cancer risk in younger women. A survey (338 high school students aged 14 to 19) was conducted to assess their perceptions of breast cancer etiologies and risk behaviors. Survey results indicated 20% to 50% of students had misperceptions about breast cancer risk, and the mean knowledge score for all items was 65.47%. There were no differences in students with familial breast cancer histories or those instructed in breast self-exam. Approximately 12% reported being fearful, avoiding public health messages, and approximately 20% thought breastfeeding increased breast cancer risk. The findings suggest that school-based programs are not addressing misperceptions related to breast health effectively. A National Cancer Institute survey found that NPs and other providers are the most trusted sources of health information. Given the low rates of breast cancer in young women and recommendations against teaching breast self-exam, it is important for NPs to be knowledgeable about common misperceptions and address them with their patients. ©2015 American Association of Nurse Practitioners.

  2. Estimation of the cost of treatment by chemotherapy for early breast cancer in Morocco

    2010-01-01

    Background Breast cancer is the first cancer in women both in incidence and mortality. The treatment of breast cancer benefited from the progress of chemotherapy and targeted therapies, but there was a parallel increase in treatment costs. Despite a relatively high incidence of many sites of cancer, so far, there is no national register for this disease in Morocco. The main goal of this paper is to estimate the total cost of chemotherapy in the early stages of breast cancer due to its frequency and the chances of patients being cured. This study provides health decision-makers with a first estimate of costs and the opportunity to achieve the optimal use of available data to estimate the needs of antimitotics and trastuzumab in Morocco. Method We start by evaluating the individual cost according to the therapeutic sub-groups, namely: 1. Patients needing chemotherapy with only anthracycline-based therapy. 2. Patients needing chemotherapy with both anthracycline and taxane but without trastuzumab. 3. Patients needing trastuzumab in addition to chemotherapy. For each sub-group, the protocol of treatment is described, and the individual costs per unit, and for the whole cycle, are evaluated. Then we estimate the number of women suffering from breast cancer on the basis of two data bases available in Morocco. Finally, we calculate the total annual cost of treatment of breast cancer in Morocco. Results The total cost of breast cancer in Morocco is given in Moroccan dirhams (MAD), the US dollar at the current exchange rate (MAD 10 = USD 1.30) and in international dollars or purchasing power parity (MAD 10 = PPP 1.95). The cost of a therapy with trastuzumab is 8.4 times the cost of a sequential chemotherapy combining anthracycline and taxane, and nearly 60 times the cost of chemotherapy based on anthracycline alone. Globally, between USD 13.3 million and USD 28.6 million need to be devoted every year by the Moroccan health authorities to treat women with localized breast

    Axillary nodal status is the most significant prognosticator for predicting survival and guiding adjuvant therapy in breast cancer patients. Sentinel lymph node biopsy (SLNB) represents a minimally invasive procedure with low morbidity for staging axillary nodal status. In this article we review and report our experiences in patients with early breast cancer who underwent SLNB at the Revlon/UCLA Breast Center. Between September 1998 and May 2000, a total 83 SLNBs were performed in 81 patients with proven breast cancer and negative axillary examination who elected to have SLNB as the first step of nodal staging. Two patients had bilateral breast cancer. SLNB was localized by using both 99Tc sulfur colloid (83 cases) and isosulfan blue dye (75 cases). Data of these patients were prospectively collected and analyzed. The clinical and pathologic characteristics of women with positive and negative sentinel lymph nodes (SLNs) were compared to identify features predictive of SLN metastasis. Of the 83 cases, the SLN was successfully localized in 82 (98.8%). Sixty-three percent of patients had SLNs found in level I only, 18.3% in both level I and II, and 4.9% in level II alone. The vast majority (84.3%) of these cases had T1 breast cancer with an average size of 1.55 cm for the entire series. Twenty-three patients (28%) had positive SLNs, with an average of 1.5 positive SLNs per patient. Fifteen had metastases detected by hematoxylin and eosin staining and 8 had micrometastases detected by immunohistochemistry (IHC) using anticytokeratin antibodies. Ten of the former group agreed to and 2 of the latter group opted for full axillary lymph node dissection (ALND). An average of 17.5 lymph nodes were removed from each ALND procedure. Additional metastases or micrometastases were found in seven patients (in a total of 28 lymph nodes). Three patients with completely negative SLNs experienced additional axillary lymph node removal due to their election of free flap reconstruction

    Although germline TP53 mutations have been identified in women with breast cancer from families meeting Li-Fraumeni criteria, their contribution to breast cancer per se is not well known, but is thought to be minimal. We aimed to determine the prevalence of germline TP53 mutations in subgroups of early-onset breast cancer. Germline TP53 mutation status was assessed by DNA sequencing, screening for heterozygous single-nucleotide polymorphisms, and Multiplex Ligation-Dependent Probe Amplification analyses. From an Australian population-based series of invasive breast cancers, we studied (a) 52 women diagnosed before age 30 years unselected for family history [very early-onset (VEO)] and (b) 42 women diagnosed in their 30s with two or more first- or second-degree relatives with breast or ovarian cancer [early-onset family history (EO-FH)]. Of the VEO group, two (4%) had a mutation: G13203A (exon 6 missense) in a 24-year-old and a large 5,338-bp genomic deletion in a 26-year-old. Neither had a family cancer history that met Li-Fraumeni criteria. Of the EO-FH group, three (7%) had a mutation: T13240G (a known intron 5 splicing mutation) in a 36-year-old from a classic Li-Fraumeni family; G12299A (exon 4 missense) in a 33-year-old from a Li-Fraumeni-like family; and 14058delG (exon 7 frame-shift) in a 39-year-old with a family cancer history that did not meet Li-Fraumeni criteria. Germline TP53 mutations play a larger role in early-onset breast cancer than previously thought, and in this context, can be evident outside clinically defined Li-Fraumeni families.

    Post partum hemorrhage is a major problem that jeopardizes maternal health. Its prevention can save mothers' life postnatal, through early initiation of breast-feeding. So, the study aimed to explore the effect of early initiation of breast feeding on the amount of vaginal blood loss during the fourth stage of labor. A convenient sample of one hundred primiparae was selected from the delivery unit & post partum unit of El-Shatby Maternity University Hospital in Alexandria. The study subjects were divided equally into experimental group (early breast feeding group) and control group (late breast feeding group). Two tools were developed and used for data collection. A specially designed interview questionnaire was used during early first stage of labor to collect data about general characteristics of the study subjects. An observational checklist was used during the fourth stage of labor to collect data about uterine characteristics, number of feeds and the amount of blood loss. The early breast-feeding group started feeding immediately after placental delivery, while late breast feeding group started breast- feeding after the first two hours postnatally. The amounts of blood loss for both groups were calculated. The findings of the study revealed that early initiation & increased frequency of breast-feeding could decrease the amount of blood loss during the fourth stage of labor. Therefore, maternity and pediatric nurses have to encourage mothers to start breast-feeding early. They have to explain how breast-feeding is beneficial for both mother and child.

    Mothers of preterm infants are more likely to discontinue breast feeding early than mothers of term infants. We evaluated the effect of early discharge with tube feeding of preterm infants under close supervision by paediatric nurse specialists on the duration of breast feeding. Case-control study. Medium/high-care neonatal unit of a large district general hospital. Preterm infants (<37 weeks' gestational age). Early discharge with tube feeding under close supervision by paediatric nurse specialists or regular follow-up of preterm infants discharged with oral feeding. Duration of breast feeding assessed by telephone interview 6 months after birth. There were 50 preterm infants in the early discharge group and 78 in the control group. Mothers in the early discharge group continued to breast feed longer than mothers in the control group (log rank test, p = 0.028). Four months after discharge, 63% of preterm infants in the control group were fed formula compared to 36% in the early discharge group (95% CI for difference 9% to 43%, p = 0.04). The relative risk of breast feeding cessation 6 months after birth in the early discharge group compared to the control group was 0.63 (95% CI 0.41 to 0.96). After adjustment for smoking, gestational age and birth weight, this relative risk was 0.67 (95% CI 0.43 to 1.05). Close supervision and follow-up by paediatric nurse specialists of preterm infants discharged early with tube feeding appears to increase duration of breast feeding. A randomised controlled trial to confirm these findings is warranted.

    Previous studies showed that after breast-conserving surgery for breast cancer, radiotherapy may be applied to the portion of the breast where the primary tumour was removed (partial breast irradiation (PBI), avoiding the irradiation of the whole breast. We developed a procedure of PBI consisting of a single high dose of radiotherapy of 21 Gy with electrons equivalent to 58-60 Gy in fractionated doses, delivered during the surgical session by a mobile linear accelerator, positioned close to the operating table. From July 1999 to December 2006, 1246 patients with primary carcinoma of less than 2.5-cm maximum diameter, mostly over 48 years, were treated with electron intra-operative radiotherapy (ELIOT) at a single dose of 21 Gy. After a follow-up from 0.3 to 94.7 months (median 26), 24 (1.9%) patients showed a local recurrence and 22 developed distant metastases. Sixteen patients died, seven from breast carcinoma and nine from others causes. The five-year crude survival was 96.5%. Six (0.5%) developed severe breast fibrosis, which resolved in 2-3 years. An additional 40 patients suffered for mild fibrosis. Cosmetic results were good. Electron intra-operative radiotherapy is a safe method for treating conservatively operated breasts and avoids the long period of post-operative radiotherapy, greatly improving the quality of life and reduces the cost of radiotherapy. ELIOT markedly reduces the radiation to normal surrounding tissues and deep organs. Results on short- and medium-term toxicity are good. Data on local control are encouraging.

    Breast feeding may contribute to neurological development and hence mental health. However, associations from Western populations are unclear, and most likely confounded by socioeconomic position (SEP), making evidence from other sociocultural settings valuable. We examined whether breast feeding was associated with early adolescent emotional and behavioural problems, self-esteem and depressive symptoms in a non-Western developed setting, where socioeconomic patterning of breast feeding differs from but other postnatal characteristics are similar to Western settings. The adjusted associations of breast feeding with emotional and behavioural problems assessed from parent-reported Rutter z-score at ~11 years (n=5598, 67% follow-up), self-reported self-esteem z-score at ~11 years (n=6937, 84%) and depressive symptoms assessed from self-reported Patient Health Questionnaire-9 z-score at ~13 years (n=5797, 70%) were examined using multivariable linear regression in a population-representative Hong Kong Chinese birth cohort, 'Children of 1997'. Mothers from families with higher education tended to start but not sustain breast feeding, whereas migrant mothers tended to start and sustain breast feeding. Breast feeding for 3+ months had mostly null associations with Rutter score, self-esteem or depressive symptoms adjusted for sex, age, survey mode, SEP, parents' age, birth weight-for-gestational age, birth order and secondhand smoke exposure, although partial breast feeding for any length of time or exclusive breast feeding for <3 months was associated with poorer behaviour (higher Rutter z-score (0.10, 95% CI 0.05 to 0.16)) and lower self-esteem (-0.09, 95% CI -0.14 to -0.04). In a non-Western developed setting, breast feeding was inconsistently associated with several early adolescent mental health measures suggesting a reflection of setting specific unmeasured confounding.

    The generation of antitumour immunity depends on the nature of dendritic cell (DC)–tumour interactions. These have been studied mostly by using in vitro-derived DC which may not reflect the natural biology of DC in vivo. In breast cancer, only one report has compared blood DC at different stages and no longitudinal evaluation has been performed. Here we conducted three cross-sectional and one one-year longitudinal assessments of blood DC in patients with early (stage I/II, n=137) and advanced (stage IV, n=36) disease compared to healthy controls (n=66). Patients with advanced disease exhibit markedly reduced blood DC counts at diagnosis. Patients with early disease show minimally reduced counts at diagnosis but a prolonged period (1 year) of marked DC suppression after tumour resection. While differing in frequency, DC from both patients with early and advanced disease exhibit reduced expression of CD86 and HLA-DR and decreased immunostimulatory capacities. Finally, by comparing a range of clinically available maturation stimuli, we demonstrate that conditioning with soluble CD40L induces the highest level of maturation and improved T-cell priming. We conclude that although circulating DC are compromised by loco-regional and systemic breast cancer, they respond vigorously to ex vivo conditioning, thus enhancing their immunostimulatory capacity and potential for immunotherapy.

    Patient-reported toxicities help to appraise the breast cancer treatment experience. Yet extant data come from clinical trials and health care claims, which may be biased. Using patient surveys, the authors sought to quantify the frequency, severity, and burden of treatment-associated toxicities. Between 2013 and 2014, the iCanCare study surveyed a population-based sample of women residing in Los Angeles County and Georgia with early-stage, invasive breast cancer. The authors assessed the frequency and severity of toxicities; correlated toxicity severity with unscheduled health care use (clinic visits, emergency department visits/hospitalizations) and physical health; and examined patient, tumor, and treatment factors associated with reporting increased toxicity severity. The overall survey response rate was 71%. From the analyzed cohort of 1945 women, 866 (45%) reported at least 1 toxicity that was severe/very severe, 9% reported unscheduled clinic visits for toxicity management, and 5% visited an emergency department or hospital. Factors associated with reporting higher toxicity severity included receipt of chemotherapy (odds ratio [OR], 2.2; 95% confidence interval [95% CI], 2.0-2.5), receipt of both chemotherapy and radiotherapy (OR, 1.3; 95% CI, 1.0-1.7), and Latina ethnicity (OR vs whites: 1.3; 95% CI, 1.1-1.5). A nonsignificant increase in at least 1 severe/very severe toxicity report was observed for bilateral mastectomy recipients (OR, 1.2; 95% CI, 1.0-1.4). Women with early-stage invasive breast cancer report substantial treatment-associated toxicities and related burden. Clinicians should collect toxicity data routinely and offer early intervention. Toxicity differences observed by treatment modality may inform decision making. Cancer 2017;123:1925-1934. © 2017 American Cancer Society. © 2017 American Cancer Society.

    Rates of nonadherence to aromatase inhibitors (AIs) among Medicare beneficiaries with hormone receptor-positive early breast cancer are high. Out-of-pocket drug costs appear to be an important contributor to this and may be addressed by eliminating copayments and other forms of patient cost sharing. The authors estimated the incremental cost-effectiveness of providing Medicare beneficiaries with full prescription coverage for AIs compared with usual prescription coverage under the Medicare Part D program. A Markov state-transition model was developed to simulate AI use and disease progression in a hypothetical cohort of postmenopausal Medicare beneficiaries with hormone receptor-positive early breast cancer. The analysis was conducted from the societal perspective and considered a lifetime horizon. The main outcome was an incremental cost-effectiveness ratio, which was measured as the cost per quality-adjusted life-year (QALY) gained. For patients receiving usual prescription coverage, average quality-adjusted survival was 11.35 QALYs, and lifetime costs were $83,002. For patients receiving full prescription coverage, average quality-adjusted survival was 11.38 QALYs, and lifetime costs were $82,728. Compared with usual prescription coverage, full prescription coverage would result in greater quality-adjusted survival (0.03 QALYs) and less resource use ($275) per beneficiary. From the perspective of Medicare, full prescription coverage was cost-effective (incremental cost-effectiveness ratio, $15,128 per QALY gained) but not cost saving. Providing full prescription coverage for AIs to Medicare beneficiaries with hormone receptor-positive early breast cancer would both improve health outcomes and save money from the societal perspective.

    Background Breast cancer (BC) has been described as the leading cause of cancer deaths among women especially in the developing world including sub Saharan Africa (SSA). Delayed presentation and late diagnosis at health facilities are parts of the contributing factors of high BC mortality in Africa. This review aimed to appraise the contributing factors to delayed breast cancer presentation and diagnosis among SSA women. Methods Five databases encompassing medical and social sciences were systematically searched using predefined search terms linked with breast cancer presentation and diagnosis and sub Saharan Africa. Reference lists of relevant papers were also hand searched. Quality of quantitative and qualitative articles were assessed using the National Institute of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies and the Critical Appraisal Skills Programme (CASP) quality appraisal checklist. Thematic analysis was used to synthesize the qualitative studies to integrate findings. Results Fourteen (14) quantitative studies, two (2) qualitative studies and one (1) mixed method study merited inclusion for analysis. This review identified low knowledge of breast cancer among SSA women. This review also found lack of awareness of early detection treatment, poor perception of BC, socio-cultural factors such as belief, traditions and fear as factors impacting African women’s health seeking behavior in relation to breast cancer. Conclusion Improving African women’s knowledge and understanding will improve behaviors related to breast cancer and facilitate early presentation and detection and enhance proper management and treatment of breast cancer.

    Inherited susceptibility to breast cancer is associated with an early onset and bilateral disease. The extent of familial risks has not, however, been fully assessed in population-based incidence studies. The purpose of the study was to quantify the risks for cancers of the breast, ovary and other sites of close relatives of women in whom breast cancer was diagnosed at an early age. Records collected between 1943 and 1990 at the Danish Cancer Registry were searched, and 2860 women were found in whom breast cancer was diagnosed before age 40. Population registers and parish records were used to identify 14 973 parents, siblings and offspring of these women. Cancer occurrence through to 31 December 1993 was determined within the Cancer Registry's files and compared with national incidence rates. Women with early-onset breast cancer were at a nearly fourfold increased risk of developing a new cancer later in life (268 observed vs 68.9 expected). The excess risk was most evident for second cancer of the breast (181 vs 24.5) and for ovarian cancer (20 vs 3.3). For mothers and sisters, risks for cancers of the breast and ovary were significantly increased by two- to threefold. Bilateral breast cancer and breast–ovarian cancer were very strong predictors of familial risks, with one in four female relatives predicted to develop breast and/or ovarian cancer by age 75. Mothers had a slightly increased risk of colon cancer, but not endometrial cancer. The risk for breast cancer was also increased among fathers (standardized incidence ratio 2.5; 95% CI 0.5–7.4) and especially brothers (29; 7.7–74), although based on small numbers. The risk for prostatic cancer was unremarkable. In this large population-based survey, the first-degree relatives of women who developed breast cancer before age 40 were prone to ovarian cancer as well as male and female breast cancer, but not other tumours that may share susceptibility genes with breast cancer. © 1999 Cancer Research Campaign

    Purpose To assess the impact of pre-operative breast MRI on surgical waiting time, and to identify factors contributing to the delay. Materials and Methods A retrospective cohort study involving 1274 patients was conducted after obtaining institutional ethics review. Surgical candidates for newly diagnosed breast cancer from 2007 to 2013 at a tertiary center were divided into 2 groups: those who had pre-operative MRI and those who did not. Linear regression using matched populations was used to compare the surgical waiting times, defined as time from the date of the first positive biopsy to the date of surgery. Potential influences on surgical waiting time and subgroup analysis were obtained using median regression analysis and the Kruskal-Wallis test. Results Mean surgical waiting time was 57.9 days (95% CI: 55.6–60.1) for MRI patients, compared to 46.8 days (95% CI: 45.1–48.9) for the control group, after matching for potential confounding factors (p<0.0001). Increased surgical waiting time was associated with more favorable pathology, later year of diagnosis, older patient age, surgeon and summer time. Second-look ultrasound and subsequent biopsies were associated with increased waiting time (p = 0.001). Conclusions Pre-operative breast MRI increased surgical waiting time by 11 days using a conventional average of differences, and by 12 days after using a full matching statistical method (p<0.0001), with the main contributor being additional post-MRI procedures and imaging.

    To identify published, original, cost-effectiveness analyses presenting cost/quality-adjusted life year (QALY) ratios for trastuzumab used as an adjuvant treatment for HER2-positive early breast cancer and to evaluate the quality of reporting the favorable cost-effectiveness ratios. The terms trastuzumab adjuvant therapy, cost-effectiveness, quality-adjusted, QALY, and early breast cancer were searched in MEDLINE, PubMed, Embase, and CancerLit, as well as in Cochrane economic evaluation and reference lists from 1998 to June 2008. Only English-language publications were eligible. All published studies examining cost-effectiveness outcomes on the basis of modeling or clinical trials were included. Cost-effectiveness analysis that measured health effects in units other than QALY, life year gained, neoadjuvant data, reviews, and comments were excluded. Each study was assessed independently by 2 trained reviewers. Thirteen of the 239 articles identified met the inclusion criteria, with 23 cost-effectiveness ratios pertaining to treatment of early breast cancer. These ratios ranged from $5020/QALY to $134,610/QALY. Most studies reported favorable cost-effectiveness values (ie, below $50,000/QALY). About 84.6% were conducted using a Markov model based on data from clinical trials and 15.3% were analyzed by other economic or cost models; 84.6% reported sensitivity analysis, 11 studies (84.6%) clearly described a justification of selecting study design, and only 15.3% noted study limitations. All studies mentioned their perspective; 92.3% did not show the funding source. Methods of reporting costs, effectiveness, and time-horizons for disease states varied significantly. Nine (69.2%) studies used a discount rate of 3%, 3 studies used a discount rate of 5%, and 1 study used 3.5%. The mean quality of the studies was 4.43. Most studies presenting the frequently proposed threshold of QALY suggest that trastuzumab may be cost-effective for treatment of early breast cancer in a 1

    Treatment options for women with early-stage breast cancer have never been better, and the addition of bisphosphonates to adjuvant therapy is a valuable new tool capable of substantially improving clinical outcomes for these women. Several recent studies demonstrated that the anticancer activity of bisphosphonates is not limited to bone, and can translate into a reduction in disease recurrence, including reductions in locoregional and distant metastases. In addition, bisphosphonates maintain bone health during adjuvant therapy; this may be especially important for women who are at high risk for fracture.

    The interaction between the meiotic recombination 11 homolog A (MRE11) oncoprotein and breast cancer recurrence status remains unclear. The aim of this study was to assess the interaction between MRE11 and clinicopathologic variables in breast cancer. A dataset for 254 subjects with breast cancer (220 nonrecurrent and 34 recurrent) was used in individual and cumulated receiver operating characteristic (ROC) analyses of MRE11 and 12 clinicopathologic variables for predicting breast cancer recurrence. In individual ROC analysis, the area under curve (AUC) for each predictor of breast cancer recurrence was smaller than 0.7. In cumulated ROC analysis, however, the AUC value for each predictor improved. Ten relevant variables in breast cancer recurrence were used to find the optimal prognostic indicators. The presence of any six of the following ten variables had a high (79%) sensitivity and a high (70%) specificity for predicting breast cancer recurrence: tumor size ≥ 2.4 cm, tumor stage II/III, therapy other than hormone therapy, age ≥ 52 years, MRE11 positive cells > 50%, body mass index ≥ 24, lymph node metastasis, positivity for progesterone receptor, positivity for epidermal growth factor receptor, and negativity for estrogen receptor. In conclusion, this study revealed that these 10 clinicopathologic variables are the minimum discriminators needed for optimal discriminant effectiveness in predicting breast cancer recurrence.

    The study examines the influence of personality traits and close relationships on the coping style of women with breast cancer. A sample of 72 Italian patients receiving treatment for early stage breast cancer was recruited. Participants completed questionnaires measuring personality traits (Interpersonal Adaptation Questionnaire), interpersonal closeness (Inclusion of the Other in the Self Scale), and adjustment to cancer (Mini-Mental Adjustment to Cancer Scale). We hypothesized that diverse personality traits and degrees of closeness contribute to determine the coping styles shown by participants. Multiple regression analyses were conducted for each of the five coping styles (Helplessness/Hopelessness, Anxious Preoccupation, Avoidance, Fatalism, and Fighting Spirit) using personality traits and interpersonal closeness variables (Strength of Support Relations, and Number of Support Relations) as predictors. Women who rated high on assertiveness and social anxiety were more likely to utilize active coping strategies (Fighting Spirit). Perceived strength of relationships was predictive of using an active coping style while the number of supportive relationships did not correlate with any of the coping styles. Implications for assessment of breast cancer patients at risk for negative adaptation to the illness and the development of psychosocial interventions are discussed. PMID:25699003

    Despite a 20-year-old guideline from the National Institutes of Health (NIH) Consensus Development Conference recommending breast conserving surgery with radiation (BCSR) over mastectomy for woman with early-stage breast cancer (ESBC) because it preserves the breast, recent evidence shows mastectomy rates increasing and higher-staged ESBC patients are more likely to receive mastectomy. These observations suggest that some patients and their providers believe that mastectomy has advantages over BCSR and these advantages increase with stage. These beliefs may persist because the randomized controlled trials (RCTs) that served as the basis for the NIH guideline were populated mainly with lower-staged patients. Our objective is to assess the survival implications associated with mastectomy choice by patient alignment with the RCT populations. We used instrumental variable methods to estimate the relationship between surgery choice and survival for ESBC patients based on variation in local area surgery styles. We find results consistent with the RCTs for patients closely aligned to the RCT populations. However, for patients unlike those in the RCTs, our results suggest that higher mastectomy rates are associated with reduced survival. We are careful to interpret our estimates in terms of limitations of our estimation approach. PMID:22928097

    Purpose: To determine whether the exclusive use of radiotherapy (ERT) could be a treatment option after complete clinical response (cCR) to neoadjuvant chemotherapy (NCT) for early breast cancer (EBC). Methods and Materials: Between 1985 and 1999, 1,477 patients received NCT for EBC considered too large for primary conservative surgery. Of 165 patients with cCR, 65 patients were treated with breast surgery (with radiotherapy) and 100 patients were treated with ERT. Results: The two groups were comparable in terms of baseline characteristics, except for larger initial tumor sizes in the ERT group. There were no significant differences in overall, disease-free and metastasis-free survival rates. Five-year and 10-year overall survival rates were 91% and 77% in the no-surgery group and 82% and 79% in the surgery group, respectively (p = 0.9). However, a nonsignificant trend toward higher locoregional recurrence rates (LRR) was observed in the no-surgery group (31% vs. 17% at 10 years; p = 0.06). In patients with complete responses on mammography and/or ultrasound, LRR were not significantly different (p = 0.45, 10-year LRR: 21% in surgery vs. 26% in ERT). No significant differences were observed in terms of the rate of cutaneous, cardiac, or pulmonary toxicities. Conclusions: Surgery is a key component of locoregional treatment for breast cancers that achieved cCR to NCT.

    Racial disparity is often identified as a factor in survival from breast cancer in the United States. Current data regarding survival in patients treated in the Department of Defense Military Healthcare System is lacking. The Department of Defense Automated Central Tumor Registry (ACTUR) was queried for all women diagnosed with Stage I or II breast cancer from January 1, 1996 through December 31, 2008. Statistical analyses evaluated demographics, surgical treatment, tumor stage, and survival rates. There were 8,890 patients meeting inclusion criteria. Patients who were younger, Asian American (versus white or black), lower T and/or N stage had significantly improved survival rates. Interestingly, white and black patients demonstrated similar survival in this study. Patients with a longer period of time between diagnosis and treatment had no decrement in survival. As would be expected, patients with a longer recurrence free period enjoyed longer survival. Survival from early stage breast cancer is equivalent between white and black patients in the Department of Defense Healthcare System. This finding is contrary to reports from our civilian counterparts and may be indicative of improved access to care and overall improved cancer surveillance. © 2015 Wiley Periodicals, Inc.

    The number of older adults diagnosed with breast cancer is increasing. However, data on breast cancer characteristics, treatment, and survival in elderly women are sparse. The database of a tertiary cancer center was searched for all women aged ≥65 years who were diagnosed with early breast cancer in 2004-2007. Patients were divided into 2 age groups: 65-75 years and >75 years. Data on tumor, treatment, and outcome parameters were compared. The cohort included 390 patients. The older group underwent more mastectomies but less axillary surgery or adjuvant systemic therapy. Median overall survival (OS) was 9.5 years in the older group and not reached in the younger group; the 8-year disease-free survival rates were 85 and 88%, respectively (p = 0.27). Both age and tumor subtype had an effect on OS and recurrence rates (p < 0.001 for OS; p = 0.16 for recurrence). The worst outcome was noted in women aged >75 years with triple-negative (TN) disease. The treatment approach was different between both age groups, despite similar tumor characteristics. TN subtype presented as the most aggressive disease in both age groups. Physicians should be alert to these findings and select treatment on a case-by-case basis. © 2017 S. Karger AG, Basel.

    A consensus conference was held to investigate issues related to the local management of early breast cancer. Here, we highlight the major topics discussed at the conference and propose ideas for future studies. Regarding axillary management, we examined three major issues. First, we discussed whether the use of axillary reverse mapping could clarify the lymphatic system of breast and whether the ipsilateral arm might help avoid lymphedema. Second, the use of an indocyanine green fluorescent navigation system was discussed for intraoperative lymphatic mapping. These new issues should be examined further in practice. Finally, some agreement was reached on the importance of "four-node diagnosis" to aid in the diagnostic accuracy of sentinel nodes. Regarding breast treatment, there was general agreement that the clinical value of surgical margins in predicting local failure was dependent on the tumor's intrinsic biology and subtypes. For patients treated with preoperative chemotherapy, less extensive excision may be feasible in those who respond to systemic therapy in an acceptable manner. Most trials of preoperative chemotherapy lack outcome data on local recurrence. Therefore, there is a need for such data for overview analysis. We also agreed that radiation after mastectomy may be beneficial in node-positive cases where more than four nodes are involved. Throughout the discussions for both invasive and noninvasive disease, the investigation of nomograms was justified for major issues in the decision-making process, such as the presence or absence of microinvasion and the involvement of nonsentinel nodes in sentinel node-positive patients.

    Lymphoscintigraphy is an important part of sentinel node mapping in breast cancer patients. Sometimes star shaped artefacts due to septal penetration can be problematic during imaging. In the current study, we evaluated the possibility of high energy (HE) collimators use for lymphoscintigraphy. Twenty patients with early breast carcinoma were included. Thirty minutes after radiotracer injection (99mTc-antimony sulphide colloid), anterior and lateral images were acquired using a dual head gamma camera equipped with a parallel hole low energy high resolution (LEHR) collimator on one head and HE collimator on another head. All images were reviewed by two nuclear medicine specialists regarding detectability and number of axillary sentinel nodes and presence of star artefact. All images taken by LEHR collimators showed star artefact of the injection site. No image taken by HE collimator showed this effect. In two patients the sentinel node was visible only by HE collimator. Tumour location in both of these patients was in the upper lateral quadrant and both had history of excisional biopsy. In two patients additional sentinel node was visible adjacent to the first one only on the LEHR images. HE collimators can be used for sentinel lymph node mapping and lymphoscintigraphy of the breast cancer patients. This collimator can almost eliminate star-shaped artefacts due to septal penetration which can be advantageous in some cases. However, to separate two adjacent sentinel nodes from each other LEHR collimators perform better.

    Background Previous studies examining the relationship between micronutrient intakes and survival following diagnosis of breast cancer have reported mixed results. This may be partly due to considerable variance in amounts of micronutrients consumed from diet and supplements across studies. Methods Early stage breast cancer survivors (n=3081) completed four 24-hour dietary and supplement recalls at the baseline assessment (1995 to 2000) and were followed for a median of 9.0 years. Mean micronutrient intakes were compared to dietary reference intakes (DRI) to assess micronutrient adequacy for both users and non-users of supplements. Cox regressions were performed to assess whether intakes of selected micronutrients were associated with all-cause mortality. Results 412 deaths occurred between baseline and August 2009. Among these women, more supplement users had adequate micronutrient intakes than non-users for 15 out of 17 micronutrients. Less than 10% of supplement users (< 2% of non-supplement users) reported levels that exceeded the tolerable upper limit for each micronutrient except magnesium. After adjusting for age, tumor characteristics, and health status variables, micronutrient intakes were not significantly associated with all-cause mortality. Conclusion Dietary supplements may improve overall micronutrient intakes of breast cancer survivors. However, vitamin and mineral intakes were not associated with all-cause mortality. PMID:21391124

  7. Endocrine Disruptors and the Breast: Early Life Effects and Later Life Disease

    Breast cancer risk has both heritable and environment/lifestyle components. The heritable component is a small contribution (5–27 %), leaving the majority of risk to environment (e.g., applied chemicals, food residues, occupational hazards, pharmaceuticals, stress) and lifestyle (e.g., physical activity, cosmetics, water source, alcohol, smoking). However, these factors are not well-defined, primarily due to the enormous number of factors to be considered. In both humans and rodent models, environmental factors that act as endocrine disrupting compounds (EDCs) have been shown to disrupt normal mammary development and lead to adverse lifelong consequences, especially when exposures occur during early life. EDCs can act directly or indirectly on mammary tissue to increase sensitivity to chemical carcinogens or enhance development of hyperplasia, beaded ducts, or tumors. Protective effects have also been reported. The mechanisms for these changes are not well understood. Environmental agents may also act as carcinogens in adult rodent models, directly causing or promoting tumor development, typically in more than one organ. Many of the environmental agents that act as EDCs and are known to affect the breast are discussed. Understanding the mechanism(s) of action for these compounds will be critical to prevent their effects on the breast in the future. PMID:23417729

    Most breast cancers originate in the epithelial cells lining the breast ducts. Intraductal administration of cancer therapeutics would lead to high drug exposure to ductal cells and eliminate preinvasive neoplasms while limiting systemic exposure. We performed preclinical studies in N-methyl-N’-nitrosourea–treated rats to compare the effects of 5-fluorouracil, carboplatin, nanoparticle albumin-bound paclitaxel, and methotrexate to the previously reported efficacy of pegylated liposomal doxorubicin (PLD) on treatment of early and established mammary tumors. Protection from tumor growth was observed with all five agents, with extensive epithelial destruction present only in PLD-treated rats. Concurrently, we initiated a clinical trial to establish the feasibility, safety, and maximum tolerated dose of intraductal PLD. In each eligible woman awaiting mastectomy, we visualized one ductal system and administered dextrose or PLD using a dose-escalation schema (2 to 10 mg). Intraductal administration was successful in 15 of 17 women with no serious adverse events. Our preclinical studies suggest that several agents are candidates for intraductal therapy. Our clinical trial supports the feasibility of intraductal administration of agents in the outpatient setting. If successful, administration of agents directly into the ductal system may allow for “breast-sparing mastectomy” in select women. PMID:22030751

    Regulatory pathways that drive early hematogenous dissemination of tumor cells are insufficiently defined. Here, we used the presence of disseminated tumor cells (DTC) in the bone marrow to define patients with early disseminated breast cancer and identified low retinoic acid-induced 2 (RAI2) expression to be significantly associated with DTC status. Low RAI2 expression was also shown to be an independent poor prognostic factor in 10 different cancer datasets. Depletion of RAI2 protein in luminal breast cancer cell lines resulted in dedifferentiation marked by downregulation of ERα, FOXA1, and GATA3, together with increased invasiveness and activation of AKT signaling. Functional analysis of the previously uncharacterized RAI2 protein revealed molecular interaction with CtBP transcriptional regulators and an overlapping function in controlling the expression of a number of key target genes involved in breast cancer. These results suggest that RAI2 is a new metastasis-associated protein that sustains differentiation of luminal breast epithelial cells. We identified downregulation of RAI2 as a novel metastasis-associated genetic alteration especially associated with early occurring bone metastasis in ERα-positive breast tumors. We specified the role of the RAI2 protein to function as a transcriptional regulator that controls the expression of several key regulators of breast epithelial integrity and cancer. ©2015 American Association for Cancer Research.

    Purpose To prospectively evaluate cosmetic outcomes in women treated with accelerated partial breast irradiation (APBI) using high-dose-rate (HDR) interstitial brachytherapy for early-stage breast cancer. Methods and Materials Between 2004 and 2008, 151 patients with early-stage breast cancer were enrolled in a phase II prospective clinical trial. Eligible patients had Tis-T2 tumors ≤3 cm, excised with negative margins, and with no nodal involvement. Patients received 3.4 Gy BID to a total dose of 34 Gy. Both patients and the treating radiation oncologist qualitatively rated cosmesis as excellent, good, fair, or poor over time and ascribed a cause for changes in cosmesis. Cosmetic outcome was evaluated quantitatively by the percentage breast retraction assessment (pBRA). Patients also reported their satisfaction with treatment over time. Results Median follow-up was 55 months. The rate of excellent/good cosmesis reported by patients and the treating radiation oncologist was as follows: 92% and 97% pretreatment, 91% and 97% at 3–4 months follow-up, 87% and 94% at 2 years, and 92% and 94% at 3 years. Breast infection and adjuvant chemotherapy were independent predictors of a fair/poor cosmetic outcome at 3 years. Compared to the pretreatment pBRA (7.35), there was no significant change in pBRA over time. V150 was the only significant predictor of pBRA. The vast majority of patients (86.6%) were completely satisfied with their treatment. Conclusions Patients and the treating physician reported a high rate of excellent/good cosmetic outcomes at all follow-up time points. Acute breast infection and chemotherapy were associated with worse cosmetic outcomes. Multicatheter interstitial brachytherapy does not significantly change breast size as measured by pBRA.
