Breast cancer is the leading cause of cancer-related death among women. An increased burden of thrombotic events among breast cancer patients, leading to higher mortality and morbidity rates, is well established. There are a number of genetic risk factors associated with thrombosis, but their contribution to thrombotic tendencies in patients with cancer is not completely elucidated. We aimed to investigate possible role of FV Leiden, FII G20210A, MTHFR C677T and PAI-1 4G/5G gene variants in etiopathology of breast cancer and accompanying thrombosis in cohort of Serbian patients. Our study included 316 subject divided in three groups: breast cancer patients with (97) or without (99) accompanying thrombosis and healthy control group (120). According to our results, the prevalence for all four prothrombotic gene variants were similar in cancer patients with and without thrombosis and no statistically significant difference was observed between these groups. We detected lower frequency of MTHFR 677TT genotype in breast cancer patients when compared to control group (P=0.014; OR=0.145 (95%CI 0.031-0.679)), indicated that MTHFR C677T homozygosity could play a protective role in breast cancer susceptibility. Our study noted the lack of association between common prothrombotic gene variants and increased prothrombotic risk in Serbian breast cancer patients. Also, our results point out possible role of MTHFR 677TT genotype in etiology of breast cancer, but further studies on larger cohort of patients are needed.

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 < 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 > 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 > 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.

The Impact

Abstract Objectives Given the influence of sensory signals on food intake regulation and the subsequent nutritional status, it is important to reduce the impact of commonly observed smell and taste alterations on the pleasure of eating during chemotherapy. This study aimed to examine the effect of various types of flavor enhancement on the appreciation of an appetizer by a group of patients undergoing chemotherapy. Methods Five eggplant appetizers with no seasoning (REF) or enhanced with either salt, lemon, garlic or cumin were developed. In this cross-sectional study, 36 healthy female subjects (age 58 ± 7 y) (control group) and 84 breast cancer patients (age 56 ± 11 y) treated with chemotherapy were recruited. A hierarchical cluster analysis based on patients' self-reported smell and taste abilities classified the patients in two groups: the ‘unaltered, (high sensory abilities) n = 49’ and the ‘altered, (poor sensory abilities), n = 35’ group. Participants tasted and assessed the appreciation of the reference appetizer on a visual analog scale and performed a randomized comparative liking task, by rating the appreciation for each flavor-enhanced appetizer relative to the REF (one-sample t-test). Results There was no significant difference in the appreciation of the REF appetizer between the three groups (P > 0.05). In the comparative liking task, the control group rated similarly the appreciation between the flavor-enhanced and the REF appetizers except for the cumin-enhanced appetizer, which was appreciated significantly more than the REF (P < 0.001). Patients in both ‘altered’ and ‘unaltered’ groups appreciated similarly the cumin appetizer (P > 0.05), more the salt and garlic-enhanced appetizers (P ≤ 0.001, P = 0.005, respectively) and significantly less the lemon-enhanced appetizer relative to the REF (P = 0.029), confirming a tendency for patients to reject acid-flavored foods. Conclusions The salt and garlic enhancements were appreciated by the patients independent of the stage of chemotherapy or the severity of smell and taste alterations. Flavor enhancement seems a good strategy to maintain the pleasure of eating in patients undergoing chemotherapy. Further research is still needed on the appreciation and intake of a complete meal (starter, main course, dessert). Funding Sources APICIL and ELIOR groups.

BACKGROUND Background: Postoperative Fatigue Syndrome (POFS) occurs in almost every patient who has undergone major surgery. With the ever-increasing attention of people on rehabilitation treatment, POFS has received unprecedented attention. OBJECTIVE Objective: Based on modern data analysis, acupuncture treatment is optimized intelligently, and its efficacy in breast cancer patients with POFS is explored. METHODS Methods: In this study, the acupuncture and moxibustion in traditional Chinese medicine were combined to optimize the formation of warm acupuncture therapy, and then the research on warm acupuncture was optimized using modern data analysis methods. At first, the statistics of personal information and operation of 60 patients with breast cancer was carried out. The statistical results were analyzed by rank sum test and independent sample T test. The Visual Analogue Scale (VAS), Brief Profile Of Mood State (BPOMS), and Identity-Consequence Fatigue Scale (ICFS) were utilized to analyze the fatigue degree, mental state, and fatigue state of the patients. RESULTS Results: There was no significant difference in age (U = 473.34, P = 0.583) and education level (U = 479.20, P = 0.613) between the experimental group and the control group (P > 0.05), which were comparable. Compared with the control group, the VAS values of the experimental group on the 3rd day (P = 043), 7th day (P = 0.039), and 14th day (P = 0.030) of postoperative treatment were significantly reduced, with significant differences (P < 0.05). In the experimental group, the BPOMS values on the 3rd day (P = 0.042), 7th day (P = 0.035), and 14th day (P = 0.031) of postoperative treatment were significantly reduced, with significant differences (P < 0.05). The ICFS values of the experimental group on the 3rd day (P = 046), 7th day (P = 0.037), and 14th day (P = 0.031) of postoperative treatment were significantly reduced, with significant differences (P < 0.05). The variance of transferrin levels was uniform on the 7th day after operation (F = 0.679, P = 0.433 > 0.005), with a significant difference (T = -2.985, P = 0.008 < 0.05). CONCLUSIONS Conclusions: Warm acupuncture therapy could effectively improve the POFS of breast cancer patients, which was a safe and effective treatment. CLINICALTRIAL

Background: Breast cancer has ranked number one cancer among Indian females. Women undergoing chemotherapy experience many side effects including alteration in their body image. The present study assessed effectiveness of yoga on anxiety, depression and stress level of breast cancer patients undergoing chemotherapy.Methods: Quantitative Research approach and Randomized Clinical Controlled Trial with Time series design was adopted in the present study. The consecutive sampling technique was done to recruit 100 breast cancer patients fulfilling the eligibility criteria. Recruited patients were randomized to control (N=52) and experiment (N=48) groups by concealed randomization. Written informed consent was taken from each participant. Baseline data was collected during cycle one by using Anxiety depression and stress scale. The patients in the experimental group were taught Diaphragmatic breathing, systematic relaxation and alternate nostril breathing and Joints and Gland neck and shoulder exercises, and were instructed to practice them twice daily at home. They were supervised in practicing these when they received second, third, fourth, fifth and sixth cycles of chemotherapy. Participants in control group received routine care. Data was again collected after 21 days during second, third, fourth, fifth and sixth cycles of chemotherapy.Results: Analysis revealed that at the baseline breast cancer patients in control and experimental group were homogenous in terms of their Sociodemographic and anxiety depression and stress scores. After the yoga intervention the experimental group showed statistically significant difference in anxiety scores from control group during second, third and sixth cycles (p 0.01, p 0.02, p 0.02), in depression score during the second, third, fourth, fifth and sixth cycles (p 0.02, p 0.02, p 0.02, p 0.001, p 0.000), and in stress scores during third cycle (p 0.01) of chemotherapy.Conclusions: On the basis of findings of the study it was concluded that yoga was effective in reducing the anxiety, depression and stress of breast cancer patients undergoing chemotherapy. Therefore, it is recommended as complementary therapy for patients receiving treatment for cancer.

e14182 Background: Metformin is one of the most commonly prescribed drugs for type 2 diabetes, and some reports have suggested that metformin may reduce cancer risk. Diabetics treated with metformin have a 23% reduction in the risk of cancer, including breast cancer. In addition, it is reported that the breast cancer patients with metformin treatment for diabetes showed favorable prognosis compared with those without metformin treatment. However, the mechanism underlying the positive effects of metformin on cancer treatment remains unclear. Methods: We conducted a prospective study to evaluate the effect of preoperative metformin on early breast cancer patients. The patients took a daily dose of metformin orally for 7 to 21 days before surgery. We evaluated the effects on immunological factors (TILs, CD4+, CD8+, PD-L1 and ALDH1) by comparing core needle biopsies (CNB) obtained before surgery with surgical specimens. Results: Seventeen breast cancer patients were enrolled in this prospective study and administered metformin before surgery, during the period from January to December 2016. We analyzed 59 patients who received surgery during the same period as a control group. In the control group, there was no significant difference in TILs between CNB and surgical specimens (Rs = 0.63). In the metformin group, TILs were negative in CNB and surgical specimens of 15 (88%) and 8 (48%) cases, low in 2 (12%) and 8 (48%), and intermediate in 0 and 1 (6%), respectively. These TILs increases were confirmed in 5 (29%) patients (p = 0.09), while a decrease was confirmed in 2 (12%). The expressions of CD4+ and CD8+ by TILs were increased in 41% and 18% of surgical specimens, respectively. (p = 0.02, p = 0.09) However, there was no statistically significant difference in these immunological factors and PD-L1 or ALDH1 expression between before and after metformin. Conclusions: In our small cohort, preoperative metformin administration shows positive impact on CD4 positive lymphocytes significantly and has tendency of increasing both TILs and CD8 positive lymphocytes. However, we should keep in mind that our sample size is small. Further study is necessary to uncover the mechanisms of favorable effects of metformin on breast cancer patients.

Introduction: The associations between programmed cell death ligand 1 (PD-L1) and the prognosis of various cancers have always been a research topic of considerable interest.However, the prognostic value of PD-L1 in breast cancer patients remains a controversial subject. We aimed to evaluate the role of programmed death-1 receptor and programmed death ligand-1 (PD-1/PD-L1) expressing lymphocytes, monocytes and granulocytes, as potential mechanism of immune escape in breast cancer patients. Also, serum levels of Bcl-2 were analyzed among patients with different stages of breast cancer. Material and Methods: The study was conducted on a total of seventy-five females; fifty-five of them represented the breast cancer females at early (24 females) and advanced (31 females) stages and 20 ages matched female donors represented the control group. Patients were recruited from the Cancer Research and Management Department, Medical Research Institute, Alexandria University. Venous blood samples obtained from all females under study were used for determination of PD-1/PD-L1 expression using flowcytometry technique and measurement of Bcl-2 serum levels using ELISA technique. Results: Significantly higher expression levels of PD-L1 were found in patients with positive lymph node, advanced tumor stage, histological grade II, tumor size T2, ER, PR, Her-2 negativity and TNBC subtype. Whilst a general increase in PD-1 positive expression between the breast cancer patients and control group regarding percentage and MFI of positive PD-1 expressing monocytes and granulocytes. Also, the results showed a highly significant association between PD-1+ and PD-L1+ expression in early and advanced breast cancer patients (p<0.0001). There was a significant increase in the mean of Bcl-2 serum concentration in patients compared to healthy individuals. Finally, the results showed that Bcl-2 serum concentration correlated positively with positive PD-L1+ expressing granulocytes. While the correlation between serum Bcl-2 and PD-1+ expressing lymphocytes, monocytes and granulocytes did not show any statistical significance. Conclusions: Our study suggested that PD-L1 could serve as an important target for antibody based immunotherapies, especially in the TNBC, where treatment options are limited. The direct correlation between PD-L1+ expression and serum Bcl-2 concentration may explore a role of apoptotic machinery in the pathogenesis of breast cancer.

166 Background: Nipple-sparing mastectomy (NSM) has been gathering increased recognition as an alternative to more traditional mastectomy approaches. However, the oncological safety of these procedures is still to be elucidated. The purpose of this study is to investigate technical feasibility of NSM without increasing the risk of local recurrence and complications. Methods: Ninety-eight stage 0-III breast cancer patients received NSM between January 2001 and April 2012 at Keio University Hospital. Eligible patients were without skin involvement and not indicated for breast-conserving therapy by preoperative imaging. The pathological analysis of the subareolar tissue was performed and nipple-areolar-complex (NAC) would be removed if positive. Four hundred seventy-four breast cancer patients who had mastectomy during the same period were used as a control group. Results: The median age was 46.0 years (range 29–68). The mean clinical tumor size was 2.8±1.2cm and the mean distance between the nipple and the tumor was 2.5±1.7cm. Ninety-one patients (92.9%) had clinically node-negative status. NAC involvement was observed in 3 patients (3.1%). Three patients (3.1%) presented with epidermal necrosis. After a median follow-up period of 37.3 months (range 1-136), there were 7 recurrences (7.1%), including 4 local recurrences (4.1%) and 3 distant metastases (3.1%). There was no statistically significant difference in local recurrence between the patients with NSM and mastectomy (4.1% vs. 3.2%; p=0.16). Immediate and delayed reconstruction was performed in 2 cases (2.0%) and 41 cases (41.8%), respectively. Conclusions: Our results suggested NSM may provide oncologic safety for strongly motivated and carefully selected patients.

Background Thanks to immense improvements in technology over the past few decades, we have witnessed a major shift towards the idea that breast cancer results from a combined effect of multiple common alleles conferring low risk. This study investigates the role of 3 nonsynonymous SNPs in the DNA repair genes XRCC1 (R399Q), RAD51 (G135C) and TP53 (Arg72Pro) in breast cancer in Serbian women. Patients and Methods Cases of BRCA1/2-negative hereditary breast cancer (n = 52), sporadic breast cancer (n = 106) and age-matched cancer-free female controls (n = 104) were obtained from the Institute for Oncology and Radiology of Serbia's blood bank. Restriction fragment length polymorphism analysis was used for genotyping. Descriptive analyses included genotype and allelic frequencies; the odds ratio and 95% confidence interval were calculated as an estimate of the relative risk. Results A significant difference in QQ+RQ versus RR genotype distribution of XRCC1 was observed between hereditary breast cancer patients and cancer-free controls. The association was confirmed among young breast cancer patients from these high-risk families. The existence of 3 recessive alleles in the RAD51 and XRCC1 genotype combination showed an association with hereditary breast cancer. Odds ratio analysis indicated a strong protective role of the RAD51 GG + TP53 ArgArg + XRCC1 RR combined genotype against hereditary breast cancer negative for BRCA1/2 mutations. Conclusions The XRCC1 R399Q polymorphism showed an association with increased breast cancer risk in Serbia, especially in the hereditary form of the disease and in young breast cancer patients. Dominant alleles of RAD51, TP53 and XRCC1 combined genotypes indicated a strong protective role against hereditary breast cancer.

AbstractTamoxifen is widely used in the treatment of breast cancer and associated with an increased risk of thromboembolism (TE). An elevated homocysteine is one of the risk factors for TE. The aim of the study was to assess the effect of tamoxifen on serum homocysteine levels in breast cancer patients. We performed a case-control study in 20 female subjects to evaluate the relationship between homocysteine levels, and 5,10-methylenetetrahyrofolate reductase (MTHFR) C677T and dihydrofolate reductase (DHFR) 19-bp intron-1 deletion polymorphisms in breast cancer patients and in control subjects. It was observed that homocysteine levels were decreased during tamoxifen therapy, but this finding was not statistically significant. There was also no statistically significant difference in homocysteine levels between the two groups (p> 0.05). MTHFR C677T and DHFR 19-bp deletion polymorphisms were not associated with serum homocysteine value in either group.
