Abstract
PURPOSE To determine the feasibility and acceptability of using a patient decision aid (DA) for women with elevated breast cancer risk who are considering MRI screening. METHODS This pilot study employed a mixed methods design to develop, modify, and test an interactive DA. The DA was administered among a consecutive patient sample with an estimated Tyrer-Cuzick v.8 lifetime breast cancer risk of 20% or greater and without a pathologic genetic mutation. The decisional conflict scale was used to measure decisional conflict. Post-intervention provider and patient feedback evaluated shared decision-making, feasibility, and acceptability. RESULTS Twenty-four patients participated, with a median age of 44 years. Prior to DA use, sixteen patients (67%) were unsure whether to add MRI to their screening, six patients elected MRI (25%), and two patients declined MRI (8%). Following DA use, thirteen of sixteen of the initially undecided participants (81%) established a preference, with eleven electing to add MRI screening. Of participants with an initial preference, all maintained the same decision following use of the DA. Prior to the DA, the median decisional conflict score among participants was 25% (range 0-60%) compared with 0% (range 0-25%) after the DA. Healthcare providers reported that the DA was useful and easily incorporated into clinical workflow. CONCLUSIONS This pilot study shows that there may be a benefit to DA utilization in the high-risk breast cancer clinic to guide shared decision-making in establishing a screening preference. The findings warrant further research to test the use of the DA in a larger, multi-site trial.

Abstract
In Korea, the number of institutions providing breast MRI, as well as the number of breast MRIs, has recently increased. However, MRI-guided procedures, including biopsy and needle localization, are rarely performed compared to ultrasound-guided or stereotactic biopsy. As breast MRI has high sensitivity but limited specificity, lesions detected only on MRI require pathologic confirmation through MRI-guided biopsy or surgical excision with MRI-guided needle localization. Thus, we aimed to review MRI-guided procedures, including their indications, techniques, procedural considerations, and limitations.

Abstract
Background: Based on thermal temperatures around the breast, thermography is considered a promising approache providing information about the condition of the breast without any side effects. Objective: Using thermography, breast screening is highly dependent on the process of heat recognition. The angular effects in the process of thermal patterns recognition
can increase false detection. The effect can be observed in breasts with growing mammary glands. This study aims to develop a system to identify breast conditions
through analysis of temperature and thermal patterns. Material and Methods: In this experimental study, analysis of thermal patterns are performed using the Canny method, specifically detection of anomalies in the breast.
Twenty-four Wistar female rats were used as experimental animal models with group 1 (normal), group 2 (induced with DMBA), group 3 (rats with growing mammary gland).
At the end of 8 weeks, all rats were sacrificed and histopathology analysis was performed. The body temperature was measured every week using the Infrared Camera type TiS20 brand Fluke camera. Results: Histopathology indicated average temperature of 36.66 °C, 37.77 °C and above 38.87 °C in normal, growing mammary glands, and cancerous breasts, respectively.
These results revealed significantly higher heat in breasts with cancerous lesions. In the analysis of thermal pattern recognition for breast, no curve was formed in the normal group,
while cancerous and growing mammary glands demonstrated a perfectly closed curve and an imperfect curve pattern, respectively. Conclusion: Breast screening through the analysis of temperature and thermal patterns can distinguish normal, cancerous and breast with growing mammary glands.

Abstract
Circulating tumour DNA (ctDNA) is widely used in liquid biopsies due to having a presence in the blood that is typically in proportion to the stage of the cancer and because it may present a quick and practical method of capturing tumour heterogeneity. This paper outlines a simple electrochemical technique adapted towards point-of-care cancer detection and treatment monitoring from biofluids using a label-free detection strategy. The mutations used for analysis were the KRAS G12D and G13D mutations, which are both important in the initiation, progression and drug resistance of many human cancers, leading to a high mortality rate. A low-cost DNA sensor was developed to specifically investigate these common circulating tumour markers. Initially, we report on some developments made in carbon surface pre-treatment and the electrochemical detection scheme which ensure the most sensitive measurement technique is employed. Following pre-treatment of the sensor to ensure homogeneity, DNA probes developed specifically for detection of the KRAS G12D and G13D mutations were immobilized onto low-cost screen printed carbon electrodes using diazonium chemistry and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride/N-hydroxysuccinimide coupling. Prior to electrochemical detection, the sensor was functionalised with target DNA amplified by standard and specialist PCR methodologies (6.3% increase). Assay development steps and DNA detection experiments were performed using standard voltammetry techniques. Sensitivity (as low as 0.58 ng/μL) and specificity (>300%) was achieved by detecting mutant KRAS G13D PCR amplicons against a background of wild-type KRAS DNA from the representative cancer sample and our findings give rise to the basis of a simple and very low-cost system for measuring ctDNA biomarkers in patient samples. The current time to receive results from the system was 3.5 h with appreciable scope for optimisation, thus far comparing favourably to the UK National Health Service biopsy service where patients can wait for weeks for biopsy results.

Abstract
BACKGROUND Specialized breast cancer early detection programs with magnetic resonance imaging (MRI) in high-risk patients are by now well established in several countries. In Germany, such a program has been running as part of routine care since 2005. OBJECTIVES This review article will summarize current developments in high-risk screening with MRI. MATERIALS AND METHODS Experiences with the high-risk screening program in Germany over now more than 10 years as well as a review of the current literature will form the basis for this article. RESULTS The MRI of the breast is by far the most sensitive imaging modality for the detection of breast cancer and represents the back bone of high-risk screening. More than 90% of cancers detected at high-risk screening are visible on the MRI and more than 30% of cancers are detected primarily by MRI alone. However, a prerequisite for effective screening with MRI is a sufficiently high breast cancer incidence in the screened population. This is demonstrated by the fact that the positive predictive value of screening with MRI in women without a BRCA1/2 mutation in the age group between 30 and 39 years is unacceptably low with 2.9%. CONCLUSIONS In high-risk screening, MRI is the primary imaging tool with mammography and/or ultrasound added as adjunct if necessary. In women with a strong family history of breast cancer but no proven pathogenic mutation in one of the known risk genes in the index patient in the family, the high-risk screening should not routinely start at age 30, but should be postponed until the 10-year breast cancer risk passes a threshold of 5%.

Abstract
Manganese oxide (MnO) nanoparticles (NPs) can serve as robust pH-sensitive contrast agents for magnetic resonance imaging (MRI) due to Mn2+ release at low pH, which generates a ~30 fold change in T1 relaxivity. Strategies to control NP size, composition, and Mn2+ dissolution rates are essential to improve diagnostic performance of pH-responsive MnO NPs. We are the first to demonstrate that MnO NP size and composition can be tuned by the temperature ramping rate and aging time used during thermal decomposition of manganese(II) acetylacetonate. Two different temperature ramping rates (10°C/min and 20°C/min) were applied to reach 300°C and NPs were aged at that temperature for 5, 15, or 30 min. A faster ramping rate and shorter aging time produced the smallest NPs of ~23 nm. Shorter aging times created a mixture of MnO and Mn3O4 NPs, whereas longer aging times formed MnO. Our results indicate that a 20°C/min ramp rate with an aging time of 30 min was the ideal temperature condition to form the smallest pure MnO NPs of ~32 nm. However, Mn2+ dissolution rates at low pH were unaffected by synthesis conditions. Although Mn2+ production was high at pH 5 mimicking endosomes inside cells, minimal Mn2+ was released at pH 6.5 and 7.4, which mimic the tumor extracellular space and blood, respectively. To further elucidate the effects of NP composition and size on Mn2+ release and MRI contrast, the ideal MnO NP formulation (~32 nm) was compared with smaller MnO and Mn3O4 NPs. Small MnO NPs produced the highest amount of Mn2+ at acidic pH with maximum T1 MRI signal; Mn3O4 NPs generated the lowest MRI signal. MnO NPs encapsulated within poly(lactide-co-glycolide) (PLGA) retained significantly higher Mn2+ release and MRI signal compared to PLGA Mn3O4 NPs. Therefore, MnO instead of Mn3O4 should be targeted intracellularly to maximize MRI contrast.

Abstract
Breast tumor heterogeneity is a major impediment to oncotherapy. Cancer cells undergo rapid clonal evolution, thereby acquiring significant growth and invasive advantages. The absence of specific markers of these high-risk populations precludes efficient therapeutic and diagnostic management of the disease. Given the critical function of tumor microenvironment in the oncogenic circuitry, we sought to determine the expression profile of the extracellular matrix oncoprotein, extradomain-B fibronectin (EDB-FN) in invasive breast cancer. Analyses of TCGA/GTEx databases and immunostaining of clinical samples found a significant overexpression of EDB-FN in breast tumors, which correlated with poor overall survival. Significant upregulation of EDB-FN was observed in invasive cell populations generated from relatively less invasive MCF7 and MDA-MB-468 cells by long-term TGF-β treatment and acquired chemoresistance. Treatment of the invasive cell populations with an AKT inhibitor (MK2206-HCl) reduced their invasive potential, with a concomitant decrease in their EDB-FN expression, partly through the phosphoAKT-SRp55 pathway. EDB-FN downregulation, with direct RNAi of EDB-FN or indirectly through RNAi of SRp55, also resulted in reduced motility of the invasive cell populations, validating the correlation between EDB-FN expression and invasion of breast cancer cells. These data establish EDB-FN as a promising molecular marker for non-invasive therapeutic surveillance of aggressive breast cancer.

Abstract
For women with a high risk of breast cancer, early detection plays an important role. Due to the high incidence of breast cancer, and at a younger age than in the general population, screening begins earlier, and there is considerable evidence that magnetic resonance is the most sensitive diagnostic tool, and the principal American and European guidelines agree on the recommendation to perform annual magnetic resonance (with supplemental annual mammography) as an optimal mode of screening. In addition to the absence of current consensus on which patients should be included in the recommendation for magnetic resonance screening (widely discussed in the introduction of part 1 of this work), there are other aspects that are different between guidelines, that are not specified, or that are susceptible to change based on the evidence of several years of experience, that we have called «controversies», such as the age to begin screening, the possible advisability of using a different strategy in different subgroups, performing alternate versus synchronous magnetic resonance and mammography, the age at which to terminate the two techniques, or how to follow up after risk reduction surgery.The aim of the second part of the paper is, by reviewing the literature, to provide an update in relation to some of the main «controversies» in high risk screening with magnetic resonance. And finally, based on all this, to propose a possible model of optimal and updated screening protocol.

Abstract
BACKGROUND Since April 2013, the UK's National Health Service Breast Screening Programme (NHSBSP) centers have been obliged to provide services for women at the highest risk of breast cancer, including those carrying highly penetrant single gene mutations (BRCA1, BRCA2, TP53). Since then, such individuals previously undergoing surveillance in the Royal Marsden Hospital were referred to their local NHSBSP centers. We aimed to assess patient experience of surveillance provided by local NHSBSP services at 1 and 3 years after repatriation. PATIENTS AND METHODS High-risk gene mutation carriers referred to the NHSBSP for breast cancer surveillance were identified from a departmental database in the Cancer Genetics Unit and invited to complete questionnaires about their experience of surveillance under this new pathway, first in 2014 and again in 2016. RESULTS Three hundred forty-six individuals were invited to participate in 2014, of whom 182 responded (53%). A total of 464 patients were invited in 2016, of whom 246 (53%) completed the second questionnaire. Ninety-four percent of patients with residual breast tissue received some screening at the first (n = 161) and second (n = 185) time points. Ninety-one percent of patients (n = 146) received at least recommended surveillance in the year preceding the initial survey, a proportion decreasing slightly by the second time point (n = 164, 87%). Seventeen percent of individuals required additional diagnostic investigations, with cancers detected in 2%. These proportions remained stable between surveys. CONCLUSION Repatriation of high-risk individuals from Royal Marsden Hospital to NHSBSP centers has been successfully accomplished. Most individuals received appropriate recommended annual surveillance. Further improvements are required to ensure equal and timely provision of recommended surveillance.
