Abstract
Background The oxidative balance is a state of equilibrium between oxidants and antioxidants disrupted in various disorders, including BC. This study aimed to assess this equilibrium in breast cancer (BC) patients by looking at the oxidant-to-antioxidant ratio. Methods This case-control study comprised 40 women patients with breast cancer and 30 age-matched healthy individuals. The oxidation-reduction colorimetric technique was used to determine serum levels of total oxidant status (TOS) and total antioxidant capacity (TAC). The oxidant-to-antioxidant balance was estimated using the TOS- to- TAC ratio (TOS/TAC). Results The mean TOS in healthy individuals was 8.40±2.06 µmol/L, while in BC patients it was 13.31±2.16 µmol/L (P< 0.001). The mean serum level of TAC was 1.43±0.21 mmol/L in healthy individuals and 1.19±0.15 mmol/L in BC patients (P< 0.001). The mean serum TOS/TAC was 6.01±0.32 in the healthy individuals and 11.42±0.41 in the BC patients (P< 0.0001). There were direct correlations between TAC and estrogen receptor (r=0.339, P=0.038). The TOS/TAC level has a sensitivity of 100% and specificity of 83.33%, distinguishing patients with BC from healthy controls (P< 0.001). A significant trend of increasing risk with rising TOS/TAC levels was also seen [OR=3.62, (95 % CI 1.79, 7.35)]. Conclusions In breast cancer, the serum TOS to TAC ratio can better diagnose oxidative equilibrium than either component alone.

Abstract
Breast cancer (BC) is the leading cause of female cancer-related mortalities. Evidence has illustrated the role of long non-coding RNAs (lncRNA) and microRNAs (miRNA) as promising pool of protein non-coding regulators, for tuning the aggressiveness of several malignancies. This research aims to unravel the expression pattern and the emphases of the diagnostic value of the long intergenic ncRNA00511 (LINC00511) and its downstream microRNA (miR-185-3p) and the pathogenic significance of the onco-miR-301a-3p in naïve BC patients. LINC00511 was chosen and validated, and its molecular binding was confirmed using bioinformatics. LINC00511 was measured in 25 controls and 70 patients using qPCR. The association between the investigated ncRNA’s expression and the BC patients’ clinicopathological features was assessed. Receiver operating characteristic (ROC) curve was blotted to weigh out their diagnostic efficacy over the classical tumor markers (TMs). Bioinformatics and Spearman correlation were used to predict the interaction between LINC00511, miR-185-3p, and miR-301a-3p altogether to patients’ features. LINC00511 and miR-301a-3p, in BC patients’ blood, were overexpressed, and their median levels increased significantly, while miR-185-3p was, in contrast, downregulated, being decreased fourfold. LINC00511 was elevated in BC early stages, when compared to late stages (p < 0.0003). LINC00511, miR-185-3p, and miR-301a-3p showed AUC superior to classical TMs, allowing us to conclude that the investigated ncRNAs, in BC patients’ liquid biopsy, are novel diagnostic molecular biomarker signatures. Lymph node metastasis (LNM) and advanced tumor grade were directly correlated with LINC00511 significantly. Additionally, both LINC00511 and miR-301a-3p were positively correlated with the aggressiveness of BC, as manifested in patients with larger tumors (>2 cm) at (p < 0.001). Therefore, these findings aid our understanding of BC pathogenesis, in the clinical setting, being related in part to the LINC00511/miR axis, which could be a future potential therapeutic target.

Abstract
In magnetic hyperthermia, magnetic nanoparticles (MNPs) are used to generate heat in an alternating magnetic field to destroy cancerous cells. This field can be continuous or pulsed. Although a large amount of research has been devoted to studying the efficiency and side effects of continuous fields, little attention has been paid to the use of pulsed fields. In this simulation study, Fourier's law and COMSOL software have been utilized to identify the heating power necessary for treating breast cancer under blood flow and metabolism to obtain the optimized condition among the pulsed powers for thermal ablation. The results showed that for small source diameters (not larger than 4 mm), pulsed powers with high duties were more effective than continuous power. Although by increasing the source domain the fraction of damage caused by continuous power reached the damage caused by the pulsed powers, it affected the healthy tissues more (at least two times greater) than the pulsed powers. Pulsed powers with high duty (0.8 and 0.9) showed the optimized condition and the results have been explained based on the Arrhenius equation. Utilizing the pulsed powers for breast cancer treatment can potentially be an efficient approach for treating breast tumors due to requiring lower heating power and minimizing side effects to the healthy tissues.

Abstract
Breast cancer is a heterogeneous disease that accounts for 30% of all cancers diagnosed in women and over half a million deaths per year. Cancer stem cells (CSCs) make up a small subpopulation of cells within a tumor, are capable of self-renewal and, are responsible for tumor initiation, formation, and recurrence. Breast CSCs (BCSCs) have been the subject of concentrated research as potential targets for breast cancer therapies. Cell surface markers CD44+/CD24- have been established as minimum biomarkers for BCSCs and the upregulation of CD44 expression has been linked to tumor formation in numerous cancers. Additionally, the deregulation of Notch, Wnt/Frizzled/β-catenin, Hippo, and Hedgehog signaling pathways is believed to be responsible for the formation of CSCs and lead to tumor formation. Tumor heterogeneity is a key feature of therapy resistance and a major challenge. CSCs are predominantly senescent and inherently immune to chemotherapy drugs which rely on an overactive cell cycle. Current therapeutic strategies include targeting CSC signaling pathways that play critical roles in self-renewal and defense. Anti-CD44 antibodies have been shown to induce terminal differentiation in CSCs resulting in a significant decrease in tumor metastasis. Additionally, targeting the tumor microenvironment has been shown to increase the effectiveness of chemotherapy drugs. In this review, we attempt to provide an overview of breast cancer, the stem of its cause, and novel therapies currently being explored.

Abstract
The abnormal contribution of long non-coding RNA (lncRNAs) expression to human tumorigenesis is still a matter of debate. Breast cancer is the most common cancer in females; it represents a terrible problem in our country. The aim of this research was to assess the role of MALAT1, as one of lncRNAs, as a potential biomarker in breast cancer. This study comprised 80 patients with breast cancer and 80 controls. MALAT1 expression was measured by RT-quantitative polymerase chain reaction (qPCR). CA15-3 was estimated using chemiluminescence immunoassay (CLIA). MALAT1 expression was significantly elevated in breast cancer cases compared to controls (P < 0.0001). By performing the ROC curve analysis, we assumed that the diagnostic sensitivity and specificity for breast cancer were 83.7% and 81.2%, respectively for MALAT1 expression and 77.5% and 82.5% respectively for CA15-3 level. Moreover, combination analysis of the 2 parameters improved the diagnostic sensitivity of CA15-3 in breast cancer. In conclusion, MALAT1 expression level was positively correlated with lymph node status, estrogen receptor (ER), tumor stage and histological grade indicating its possible prognostic value. MALAT1 expression can be used as an accurate marker for diagnosis of breast cancer, in addition it possesses a prognostic value of such disease.

Abstract
PURPOSE To describe magnetic resonance imaging (MRI) findings in patients who underwent breast-conserving surgery followed by oxidized regenerated cellulose (ORC) implantation in surgical cavity. MATERIALS AND METHODS We retrospectively reviewed 51 MRI examinations performed between January 2009 and January 2014 in 51 patients who underwent BCS with ORC implantation. RESULTS In 29/51 (57 %) cases, MRIs showed abnormal findings with three main MRI patterns: (1) complex masses: hyperintense collections on T2-weighted (w) images with internal round hypointense nodules without contrast enhancement (55 %); (2) completely hyperintense collections (17 %); and (3) completely hypointense lesions (28 %). All lesions showed rim enhancement on T1w images obtained in the late phase of the dynamic study with a type 1 curve. Diffusion-weighted imaging was negative in all MRIs and, in particular, 22/29 (76 %) lesions were hyperintense but showing ADC values >1.4 × 10(-3) mm(2)/s, while the remaining 7/29 (24 %) lesions were hypointense. In four cases, linear non-mass-like enhancement was detected at the periphery of surgical cavity; these patients were addressed to a short-term follow-up, and the subsequent examinations showed the resolution of these findings. CONCLUSION When applied to surgical residual cavity, ORC can lead alterations in surgical scar. This could induce radiologists to misinterpret ultrasonographic and mammographic findings, addressing patients to MRI or biopsy; so knowledge of MRI specific features of ORC, it is essential to avoid misdiagnosis of recurrence.

Abstract
OBJECTIVE To assess the relation of blood MT-2A expression, serum zinc, copper, Cu/Zn ratio, total antioxidant status (TAS), total oxidant status (TOS) and oxidant status index (OSI) with benign and malignant breast tumors, also, their relation to different clinical stages and grades of breast cancer. MATERIAL AND METHODS Unrelated 199 female patients with breast tumor and 120 healthy controls were enrolled in this study. Metallothionein-2A (MT-2A) expression was assessed by quantitative real-time polymerase chain reaction (RT-PCR). Serum MT-2A levels were measured by ELISA. Serum copper (Cu) and Zinc (Zn) concentrations were determined by atomic absorption spectrophotometry. Serum TOS and TAS levels were measured colorimetrically. RESULTS Our study demonstrated that blood metallothionein-2A mRNA level, serum MT-2A, copper, Cu/Zn ratio, total oxidant status and oxidant status index were significantly increased, while, serum zinc level and total antioxidant status were significantly decreased in patients with breast cancer and benign breast disease as compared to controls and in breast cancer group as compared to the benign one. CONCLUSIONS Blood metallothionein-2A expression and serum MT-2A levels could be important prognostic indices of less differentiated, more aggressive breast cancer phenotype. Disturbance of copper, zinc and oxidative stress status might contribute to the pathogenesis of breast tumor and could be useful biomarkers for diagnosing and monitoring such disease.

Abstract
BACKGROUND The purpose of this study was to describe the ultrasonographic (US) and mammographic (MX) findings in patients who underwent breast-conserving surgery followed by oxidized regenerated cellulose (ORC) implantation in the surgical cavity and their size variations in follow-up. MATERIALS AND METHODS We retrospectively reviewed 417 MX and 743 US images performed between January 2009 and January 2014 for 262 women who underwent breast-conserving surgery. All patients underwent US, only 203 women underwent MX examination. RESULTS In 170 of 262 patients, US examinations showed abnormal findings. Three main US patterns were identified: (1) complex masses: well-encapsulated ipoisoechoic lesions with circumscribed margins with internal hyperechoic nodules (56%); (2) hypoanechoic lesions without internal hyperechoic nodules (24%); and (3) completely anechoic collections (20%). Moreover, Doppler ultrasound examination was performed on all of the patients. In 95 of 203 patients, MX examinations showed abnormalities. Four main MX patterns were identified: (1) round or oval opacity with circumscribed margins (58%); (2) round or oval opacity with indistinct or ill-defined margins (17%); (3) irregular opacity with indistinct or spiculated margins (9%); and (4) architectural distortion or focal asymmetry (15%). Most of the lesions showed a decrease in size at US and MX follow-up examination and the decrease was statistically significant (P < .01). CONCLUSION When applied to the surgical residual cavity, ORC aids to control local hemorrhage and reduce the risk of postoperative infections, but can lead to alterations in surgical scar. Thus, knowledge of the radiological findings might allow avoidance of misdiagnosis of tumor recurrence or unnecessary diagnostic examinations.

Abstract
Paramount to staging and patient management is accurately measuring the size of invasive breast cancers. We assessed the accuracy of mammography (MG), ultrasonography (US), and magnetic resonance imaging (MRI) at our community-based hospital in which multiple radiologists and imaging machines are used in the care of our patients. We performed a retrospective analysis of a prospectively maintained database of 277 patients seen at our breast center from 2009 to 2010. We tabulated MG, US, and MRI-reported tumor sizes in 161 women with pathology-proven invasive breast cancer and compared the preoperative size measurements with final pathologic tumor size. In the 161 patients, 169 lesions were identified. Imaging using all three modalities was available in 47 patients. When compared with final pathology, MRI had a correlation of r = 0.75 to mean tumor size as compared with US (r = 0.67) and MG (r = 0.76). Mean tumor size was 1.90 cm by MG, 1.87 cm by US, 2.40 cm by MRI, and 2.19 cm by pathology. We were able to achieve an excellent correlation of pathologic tumor size to preoperative imaging. The absolute differences in size between the modalities were small. MRI, in select patients, added to the assessment of tumor size based on US and MG.

Abstract
Breast cancer is one of the most common and dangerous cancers. Subsurface breast cancer lesions generate more heat and have increased blood supply when compared to healthy tissue, and this temperature rise is mirrored in the skin surface temperature. The rise in temperature on the skin surface, caused by the cancerous lesion, can be measured noninvasively using infrared thermography, which can be used as a diagnostic tool to detect the presence of a lesion. However, its diagnostic ability is limited when image interpretation relies on qualitative principles. In this study, we present a quantitative thermal analysis of breast cancer using a 3D computational model of the breast. The COMSOL FEM software was used to carry out the analysis. The effect of various parameters (tumor size, location, metabolic heat generation and blood perfusion rate) on the surface temperature distribution (which can be measured with infrared thermography) has been analyzed. Key defining features of the surface temperature profile have been identified, which can be used to estimate the size and location of the tumor based on (measured) surface temperature data. In addition, we employed a dynamic cooling process, to analyze surface temperature distributions during cooling and thermal recovery as a function of time. In this study, the effect of the cooling temperature on the enhancement of the temperature differences between normal tissue and cancerous lesions is evaluated. This study demonstrates that a quantification of temperature distributions by computational modeling, combined with thermographic imaging and dynamic cooling can be an important tool in the early detection of breast cancer.

Abstract
BACKGROUND Oxidative stress and trace elements have been implicated in the development of breast cancer. However, how they contribute to the pathogenesis of the disease and the relationship between them remain unclear. In addition, most previous studies detecting one or a few oxidant/antioxidant markers failed to consider the overall oxidant/antioxidant status of the subjects. This study was designed to address this and to investigate the association between oxidative status and trace elements in the pathogenesis of breast cancer. METHODS Fifty-six patients with breast carcinoma at different clinical stages, 32 patients with benign breast tumor, and 20 healthy subjects (controls) were recruited into this study. Their serum total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), and levels of Cu, Zn, Fe, Se, Mg, and Mn were measured. RESULTS Levels of TAS, TOS, OSI, and trace elements significantly differed between the study groups. Among subgroups of patients with different clinical stages of breast cancer, the levels of all the trace elements except Zn were similar, whereas TAS, TOS, and OSI levels were all significantly different. There were significant correlations between oxidative stress parameters and levels of trace elements in patients with breast carcinoma but not in patients with benign breast tumor or in the healthy controls. CONCLUSIONS Disturbed oxidative stress status and trace element levels may contribute to the pathogenesis of breast tumors. TAS, TOS, and OSI may be useful biomarkers for monitoring the clinical status of breast cancer.

Abstract
OBJECTIVES The aim of this study was to evaluate the diagnostic accuracy of fused fluoro-deoxy-D-glucose positron emission tomography/magnetic resonance mammography (FDG-PET/MRM) in breast cancer patients and to compare FDG-PET/MRM with MRM. METHODS 27 breast cancer patients (mean age 58.9±9.9 years) underwent MRM and prone FDG-PET. Images were fused software-based to FDG-PET/MRM images. Histopathology served as the reference standard to define the following parameters for both MRM and FDG-PET/MRM: sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy for the detection of breast cancer lesions. Furthermore, the number of patients with correctly determined lesion focality was assessed. Differences between both modalities were assessed by McNemaŕs test (p<0.05). The number of patients in whom FDG-PET/MRM would have changed the surgical approach was determined. RESULTS 58 breast lesions were evaluated. The sensitivity, specificity, PPV, NPV and accuracy were 93%, 60%, 87%, 75% and 85% for MRM, respectively. For FDG-PET/MRM they were 88%, 73%, 90%, 69% and 92%, respectively. FDG-PET/MRM was as accurate for lesion detection (p = 1) and determination of the lesions' focality (p = 0.7722) as MRM. In only 1 patient FDG-PET/MRM would have changed the surgical treatment. CONCLUSION FDG-PET/MRM is as accurate as MRM for the evaluation of local breast cancer. FDG-PET/MRM defines the tumours' focality as accurately as MRM and may have an impact on the surgical treatment in only a small portion of patients. Based on these results, FDG-PET/MRM cannot be recommended as an adjunct or alternative to MRM.
