Introduction: Breast cancer is one of the major and frequent tumors in the public health sector globally. The rising global prevalence of breast cancer has aroused attention in a viral etiology. Other than genetic and hormonal roles, viruses like Epstein - Barr virus (EBV) also participate in the development and advancement of breast cancer. Aim: This study was conducted to detect the frequency of EBV genotypes in breast cancer patients and compare it with histopathological breast cancer changes. Methods: Formalin-fixed paraffin-embedded samples of breast cancer (N=60) ages ranged from 22-70 years were collected. EBV DNA was isolated, amplified, typed through PCR, and correlated with histopathological outcomes of breast cancer using SPSS software version 26. Results: Our findings suggest that among breast cancer factors, Invasive ductal carcinoma (IDC) was the most common pathological pattern found among patients (90%), observed statistically significant (p= 0.01275). In regards to clinical staging, 8 (13.3 %) patients diagnosed with stage I, 39 (65 %) with stage II, and 13 (21.6 %) with stage III reported statistically significant association (p=0.0003). EBV DNA was detected in 68.3% (41/60) breast cancer patients, reported a statistically significant difference between the prevalence of EBV in breast cancer patients and normal samples (p = 0.001). Of 41 EBV-positive samples, 40 were EBV-1, while only 1 had EBV-2 infection (p < 0.001). No influence on cancer histology was observed. Regarding the association of breast cancer with EBV, histological type (P =0.209), tumor stage (P = 0.48), tumor grade (0.356), tumor sizes (p= 0.976), age (p= 0.1055), tumor laterality (p= 0.533) and ER/PR status (p=0.773) showed no significant association. Conclusion: EBV-1 is prevalent in breast cancer patients and associated with IDC in the study area. For conclusive evidence, more studies are required based on a large sample size and by using more sensitive techniques.

3135 Background: Saliva is non-invasively accessible and informative biological fluid which has high potential for the early diagnosis of various diseases. The aim of this study is to develop machine learning methods and to explore new salivary biomarkers to discriminate breast cancer patients from healthy controls. Methods: We conducted a comprehensive metabolite analysis of saliva samples obtained from 101 patients with invasive carcinoma (IC), 23 patients with ductal carcinoma in situ (DCIS) and 42 healthy controls, using capillary electrophoresis and liquid chromatography with mass spectrometry to quantify hundreds of hydrophilic metabolites. Saliva samples were collected under 9h fasting and were split into training and validation data. Conventional statistical analyses and artificial intelligence-based methods were used to access the discrimination abilities of the quantified metabolite. Multiple logistic regression (MLR) model and an alternative decision tree (ADTree)-based machine learning methods were used. The generalization abilities of these mathematical models were validated in various computational tests, such as cross-validation and resampling methods. Results: Among quantified 260 metabolites, amino acids and polyamines showed significantly elevated in saliva from breast cancer patients, e.g. spermine showed the highest area under the receiver operating characteristic curves (AUC) to discriminate IC from C; 0.766 (95% confidence interval [CI]; 0.671 – 0.840, P < 0.0001). These metabolites showed no significant difference between C and DICS, i.e., these metabolites were elevated only in the samples of IC. The MLR yielded higher AUC to discriminate IC from C; 0.790 (95% CI; 0.699 – 0.859, P < 0.0001). The ADTree with ensemble approach showed the best AUC; 0.912 (95% CI; 0.838 – 0.961, P < 0.0001). In the comparison of these metabolites in the analysis of each subtype, seven metabolites were significantly different between Luminal A-like and Luminal B-like while, but few metabolites were significantly different among the other subtypes. Conclusions: These data indicated the combination of salivary metabolomic profiles including polyamines showed potential ability to screening breast cancer in a non-invasive way.

Objective: Contradictory reports have been published regarding the expression levels of the hormone receptors of estrogen and progesterone (ER / PR) and theirclinical importance in diagnosis of breast cancer. The aim of this study was to evaluate the relationship between pathological features of invasive and non-invasive ductal tumors by different ER / PR phenotypes. Methods: This descriptive-analytical study was performed on 74 specimens of breast cancer referred to Isfahan Hospitals for diagnosis between 2015 - 2018. After fixation of the specimens in formalin, tissue passage, cross section and H / E staining, the specimens were divided into two groups: non- invasive and Invasive ductal Carcinoma. After removing of mask, expression of different ER / PR phenotypes was performed using primary monoclonal antibody and immunohistochemically methods. Results: From 74 malignant specimens, 61 (82.4%) were in the category of invasive ductal tumors and 13 cases (17.6%) were in the category of non-invasive ductal tumors. Out of 73 patients with positive ER or PR phenotype 47 samples (63.5%) had ER + / PR +phenotypes, 6 samples had (8.1%) ER+ / PR –phenotype, 20 samples (27%) had ER- / PR + phenotype and only one sample (1.4%) had the ER- / PR- phenotype and was in the category of invasive ductal tumors. There was not detected ER- / PR- phenotype expression in non-invasive ductal tumor. Further analysis showed that there were not significant difference between ER / PR phenotype and tumor stage (p =0.36) or with tumor Grade (P=0.38), high age of menopause or post menopause (P> 0.05). Conclusion: Our data shows that expression of ER- / PR- phenotype only was detected in invasive ductal tumor. It is thought that the tumor type maybe affects the expression of different types of ER / PR hormone receptor phenotypes in breast cancer patients.

611 Background: It is estimated that approximately 10% of all breast cancer patients will develop local recurrence (LR) at 10 years. Routine surveillance for detection of early breast cancer recurrence is widely performed despite lack of conclusive evidence for an improvement in patient quality of life or potential for cure. A number of historical studies evaluating the effectiveness of routine screening for LR following treatment for early-stage breast cancer have suggested that the diagnosis of LR is more frequent during a routine visit and occurring in asymptomatic patients. However, differentiating the method of detection is not often elucidated. In this study we evaluated the manner in which patients presented with an isolated LR in clinical practice. Methods: Our routine patient follow-up consists of physical exam and mammogram every 6 mos for the first 2 years following breast conserving surgery (BCS) and yearly thereafter. We queried our prospectively collected breast cancer database (1632 patients from July 1986 - July 2004) for patients with an isolated LR following BCS (n=59 (3.6%); two patients had bilateral LRs). Medical records were not available for three patients. Results: At a median follow-up of 45 mos (range: 5–122 mos) there were 58 evaluable LRs: 15 DCIS, 31 infiltrating ductal carcinoma (IDC), 6 infiltrating lobular (ILC), 2 mixed IDC/ILC, 3 invasive cancers NOS and 1 unknown. Patient presentation was as follows: 25 were diagnosed by self-exam, 28 on screening mammogram, 2 were diagnosed by physician (includes one referral), and 3 unknown. Mammogram detected recurrences were more frequent among patients with DCIS whereas self-detected recurrences were more common in patients with IDC (79% vs 33% and 21% vs 67%, respectively; P<0.2). Mean tumor size was larger in self-presentation (2.1 cm; range: 0.8–4.5 cm) than in mammogram detected group (1.6 cm; range 0.4–6 cm). Conclusions: These findings demonstrate the value of mammography as compared to patient detected LRs. Whether a survival advantage exists remains uncertain. Nevertheless routine physician examination in this setting is highly insensitive and its further utility must be considered when devising cost-effective strategies for surveillance of breast cancer patients. No significant financial relationships to disclose.

Matrix metalloproteinases (MMPs) play significant part in the tumor development, metastasis and invasion by proteolytic degradation of basement membrane and extracellular matrix. Hence MMPs can serve as good biomarkers for carcinoma breast particularly MMP-2 in our population. Objectives: To measure the concentrations of MMP-2 in plasma of breast cancer patients and establishing their correlation with stage and grade of the disease. Study Design: Comparative cross sectional. Setting: Surgery department Madinah Teaching Hospital (MTH) and the Pathology department, The University of Faisalabad (TUF), Faisalabad. Period: 1st August, 2017 to 31st December, 2017. Material & Methods: Only females with diagnosed breast cancer disease along with staging and grading were included in the study. Females with incomplete reports, on chemotherapy or radiotherapy or having other diseases like oral squamous cell carcinoma, rheumatoid arthritis etc were excluded. ELISA kit was applied to measure the concentrations of MMP-2 in plasma of the participants. OD values were calculated at 450 nm by ELISA reader placed at Post Graduate Research Laboratory, The University of Faisalabad, Faisalabad. Data was gathered and results were finalized by using SPSS 22 for statistical assessment. Results: Age of 64(72%) breast cancer patients was within range of 30-76yrs and age for 25(28%) healthy females as controls range was 18-70yrs. Difference between ages of cases and controls using t-test was statistically highly significant. Ninety five percent cases showed invasive ductal carcinoma (IDC) as histological type. Range of MMP-2 levels in cases was 80-690 ng/mL with mean 451.02 while range of MMP-2 levels in controls was 65-830ng/mL with mean 329.72 showing statistically significant difference. Relationship of different groups of MMP-2 levels in cases with stages of breast cancer was established using chi-square test which was statistically significant, stage IIB (37.5%) and IIIA (34.4%) tumors showed higher values of MMP-2. Relationship between MMP-2 levels, grade, tumor size and node invasion was nonsignificant statistically. Conclusion: MMP-2 levels were raised in cases in comparison to healthy controls. Age of majority patients was > 45 yrs while the invasive ductal carcinoma was the main histological type. MMP-2 levels were associated with stage of the disease.

Abstract Background The objective of this study was to compare the efficacy and side effects of a single dose (Pegfilgrastim or PDL) or repeated six daily injections (Filgrastim or PDG) during chemotherapy courses in breast cancer patients in a non-inferiority clinical trial. Methods In this randomized clinical trial, 80 patients were recruited and allocated randomly to two equal arms. In one group, a single subcutaneous dose of PDL was injected the day after receiving the chemotherapy regimen in each cycle. The second arm received a subcutaneous injection of PDG for six consecutive days in each cycle of treatment. The side effects of GCF treatment and its effect on blood parameters were compared in each cycle and during eight cycles of chemotherapy. Results Hematologic parameters showed no significant differences in any of the treatment courses between the two study groups. The comparison of WBC (p = 0.527), Hgb (p = 0.075), Platelet (p = 0.819), Neutrophil (p = 0.575), Lymphocyte (p = 705) and ANC (p = 0.675) changes during the eight courses of treatment also revealed no statistically significant difference between the two study groups. Side effects including headache, injection site reaction and muscle pain had a lower frequency in patients receiving PDL drugs. Conclusion It seems that PDL is non-inferior in efficacy and also less toxic than PDG. Since PDL can be administered in a single dose and is also less costly, it can be regarded as a cost-effective drug for the treatment of chemotherapy-induced neutropenia.

Response To Neoadjuvant Chemotherapy

Purpose To understand the mechanism through which obesity in breast cancer patients is associated with poorer outcome, we evaluated body mass index (BMI) and response to neoadjuvant chemotherapy (NC) in women with operable breast cancer. Patients and Methods From May 1990 to July 2004, 1,169 patients were diagnosed with invasive breast cancer at M. D. Anderson Cancer Center and received NC before surgery. Patients were categorized as obese (BMI ≥ 30 kg/m2), overweight (BMI of 25 to < 30 kg/m2), or normal/underweight (BMI < 25 kg/m2). Logistic regression was used to examine associations between BMI and pathologic complete response (pCR). Breast cancer–specific, progression-free, and overall survival times were examined using the Kaplan-Meier method and Cox proportional hazards regression analysis. All statistical tests were two-sided. Results Median age was 50 years; 30% of patients were obese, 32% were overweight, and 38% were normal or underweight. In multivariate analysis, there was no significant difference in pCR for obese compared with normal weight patients (odds ratio [OR] = 0.78; 95% CI, 0.49 to 1.26). Overweight and the combination of overweight and obese patients were significantly less likely to have a pCR (OR = 0.59; 95% CI, 0.37 to 0.95; and OR = 0.67; 95% CI, 0.45 to 0.99, respectively). Obese patients were more likely to have hormone-negative tumors (P < .01), stage III tumors (P < .01), and worse overall survival (P = .006) at a median follow-up time of 4.1 years. Conclusion Higher BMI was associated with worse pCR to NC. In addition, its association with worse overall survival suggests that greater attention should be focused on this risk factor to optimize the care of breast cancer patients.

Angiopoietin 2

Abstract Background Breast cancer is the most common cancer among women and one of the most important causes of death among them.Angiogenesis is an important step for primary tumor growth, invasiveness, and metastases. Angiopoietins are well-recognized endothelial growth factors that are involved in angiogenesis associated with tumors. Aim To explore the diagnostic significance of serum angiopoietin-2 (Ang-2) in breast cancer and to evaluate its prognostic efficacy through studying the degree of its association with the TNM staging of the disease. Patients and Methods This study was conducted on (35) Egyptian female patients who were diagnosed as breast cancer according to histopathological examination of breast biopsy (Group 1, Breast Cancer Patients) and (25) female patients with benign breast diseases (Group II, Pathological Control Patients), in addition to (20) age - matched apparently healthy, free mammogram, females serving as healthy controls (Group III, Healthy Controls). For all participants, measurement of serum Ang-2 was done using enzyme linked immunosorbent assay (ELISA) technique. Results A highly significant increased levels of Ang-2 was observed in breast cancer patients when compared to healthy control group (Z = 4.95, p &lt; 0.01). However, no significant difference was observed in Ang-2 levels between breast cancer patients group and pathological control group (Z = 3.37, p &gt; 0.05). No significant difference was detected in Ang-2 levels in relation to TNM stage and histological grade. No significant correlation was found between Ang-2 levels and serum levels of CA15-3, hormone receptors, HER2/new receptor status (p &gt; 0.05, respectively). Conclusion This study revealed that Ang-2 serum levels were significantly increased in patient with breast cancer compared with healthy controls, indicating that high Ang-2 level is a promising non invasive biomarker for breast cancer diagnosis. However, no significant difference of Ang-2 levels was detected in relation of breast TNM staging in the population studied.

SUMMARY The production rate of cortisol in patients with early or advanced breast cancer was compared with that of controls of comparable age. The miscible pool of this hormone was raised in advanced breast-cancer patients due to a higher production rate. The plasma clearance of cortisol remained unaffected, resulting in a higher titre of cortisol (both total and unbound) in advanced breast-cancer patients. There was no significant difference in the production rate between the early breast-cancer cases and controls. The binding of cortisol to transcortin was studied in all cases. The amount of unbound cortisol was raised in advanced breast-cancer cases. There was a significant correlation between both total and unbound cortisol and the production rate of this hormone. The latter correlation suggests that there is no abnormality in the hepatic extraction of cortisol in these patients. The metabolic clearance rate was found to be of the order of the blood flow through the liver when unbound cortisol was used for its estimation, showing that it is the unbound cortisol which is removed by the liver.

Introduction Breast cancer is a leading cause of cancer-related death in women worldwide, and its metastasis is a major cause of disease mortality. Therefore, identification of the mechanisms underlying breast cancer metastasis is crucial for the development of therapeutic and diagnostic strategies. Our recent study of immunodeficient female mice transplanted with MDA-MB231 breast cancer cells demonstrated that tumor cell-derived angiopoietin-like protein 2 (ANGPTL2) accelerates metastasis through both increasing tumor cell migration in an autocrine/paracrine manner, and enhancing tumor angiogenesis. To determine whether ANGPTL2 contributes to its clinical pathogenesis, we asked whether serum ANGPTL2 levels reflect the clinical features of breast cancer progression. Methods We monitored the levels of secreted ANGPTL2 in supernatants of cultured proliferating MDA-MB231 cells. We also determined whether the circulating ANGPTL2 levels were positively correlated with cancer progression in an in vivo breast cancer xenograft model using MDA-MB231 cells. Finally, we investigated whether serum ANGPTL2 levels were associated with clinical features in breast cancer patients. Results Both in vitro and in vivo experiments showed that the levels of ANGPTL2 secreted from breast cancer cells increased with cell proliferation and cancer progression. Serum ANGPTL2 levels in patients with metastatic breast cancer were significantly higher than those in healthy subjects or in patients with ductal carcinoma in situ or non-metastatic invasive ductal carcinoma. Serum ANGPTL2 levels in patients negative for estrogen receptors and progesterone receptors, particularly triple-negative cases, reflected histological grades. Conclusions These findings suggest that serum ANGPTL2 levels in breast cancer patients could represent a potential marker of breast cancer metastasis.
