Abstract
Background: Estrogen hormone regulates cell proliferation in breast tissue physiologically. Evidences show that changes in estrogen signaling pathways, including the receptor alpha (ER&alpha), happen during breast cancer progression. ER&alpha is expressed in most breast tumors and its association with the development of low-grade tumors has been demonstrated. Single nucleotide polymorphisms (SNPs) in genes may differ in susceptibility to cancer and result in different respond to treatment in different populations. The present study aimed investigated the association between single nucleotide polymorphisms (rs2234693: C/T) in gene ESR&alpha in patients with breast cancer.
Materials and Methods: In this case-control study 150 women with breast cancer and 142 healthy women without a family history of breast cancer were enrolled. DNA was extracted from blood samples. After primer design, technique of PCR-RFLP was used and samples were genotyped by acrylamide gel electrophoresis. Statistical analyzes were performed using SPSS version 20 and chi square test and Final findings were specified.
Results: TT and CT genotypes for ra2234693: C/T site compared with the CC had 5.5 and 1.5-fold increased risk respectively. Statistically significant differences were found between cases and controls for fibrocystic disease and age at menarche.
Conclusion: We not found an association between C/T polymorphism and breast cancer. But CC and TT genotypes of this polymorphism in estrogen receptor alpha gene related with breast cancer that are consistent with the findings of some other researchers.

Abstract
Background: Breast cancer is the most common cancer and one of the main causes of cancer-related death all over the world that has become a major public health concern. Human apurinic/apyrimidinic endonuclease (ApE1) is a multifunctional protein that has an important role in the base excision repair (BER) pathway. Single- nucleotide polymorphism T>G found in exon 5 led to substitution of Asp>Glu at codon 148 (Asp148Glu). In this case-control study, we aimed to evaluate the association of this polymorphism on the risk of breast cancer in Guilan population.
Materials and Methods: To study gene polymorphism APE1 (Case- Control), blood samples were collected from 75 patients diagnosed with breast cancer and 75 control subjects, and genotyped by allele-specific PCR (AS-PCR). To estimate the association between genotype and allele frequencies in cases and controls, Chi-Square analysis was used.
Results: Analysis revealed no significant differences were found in genotype and allele distributions of ApE1 Asp148Glu polymorphism between breast cancer patients and controls (p=0.1, p=0.6 respectively) in this population.
Conclusion: Data from this study indicated no significant association between the Asp148Glu polymorphism and breast cancer risk (p=0.1). Further study is needed to clarify the impact of Asp148Glu polymorphism on the breast cancer.

Abstract
Background: Breast cancer is one of the major causes of cancer-related death and the most common solid malignancy in women worldwide. Chemerin as a new adipokine has an inflammatory activity that initiates inflammation via chemotaxis of immature DCs and macrophages. This study aimed to evaluate the level of chemerin in patients with breast cancer.
Materials and Methods: In this cross-sectional study that was performed as a case-control study, we enrolled 45 patients with breast cancer in Vali-asr hospital from June to December 2015 (age range, 18-60 years) and 40 healthy volunteers as a control group (age range, 22-56 years). The patients with invasive breast were selected before mastectomy. The level of serum chemerin was measured by ELISA kit.
Results: The results showed that the mean serum chemerin level in the breast cancer patients (1536 ±608 ng/L) was significantly lower than the normal individuals (1919±544 ng/L),(p=0.04). There is no correlation between the level of chemerin with body weight, stage of disease, duration of disease and the number of white and red blood cells.
Conclusion: With due attention to the inflammatory role of chemerin, decreasing the serum chemerin level in patients with breast cancer may be related to the consumption of chemerin in the inflammatory responses or immunosuppression by tumor. The low level of chemrerin may be suitable for tumor growth and progression.

Abstract
Background: Breast cancer is the most common cancer in Iran and breast cancer is the fifth leading cause of death among women. Diagnosis of breast cancer in early stages could increase the lifetime of more than 90% of patients. Human endogenous retroviruses are as heterochromatic parts of the genome, lack any expression. But in several categories of human cancers, including breast cancer, there is a significant increase in the level of HERV-Kenv mRNA.
Materials and Methods: In this case-control study, blood samples were collected from 40 breast cancer patients admitted in Baqiyatallah Hospital and 20 healthy individuals to study the increased expression of HERV-Kenv mRNA using specific primers and were tested by RT-PCR.
Results: Investigations on the patient and control groups showed that increased expression of mRNA was positive in 60% of patients with breast cancer and negative in all healthy subjects.
Conclusion: The results of this study showed that expression of mRNA HERV Kenv in breast cancer was increased. Since enhancement of mRNA HERV-Kenv in the blood of breast cancer patients occurs in of disease, these retroelements could be used as a diagnostic biomarker

Abstract
Background: Breast cancer is the most common cancer in women. It has been proven the association of cause of this disease with changes in several genes. One of the pathways associated with breast cancer is the folate reuptake pathway. The key enzyme of this pathway is coded by the TYMS gene. MicroRNAs control the expression of genes by binding to their regulatory regions. In this study, we evaluated changes in the regulatory region of TYMS gene with demographic characteristics (including the grade of cancer and metastasis) in breast cancer patients.
Materials and Methods: In this study, the regulatory region of TYMS gene was investigated using related bioinformatics software. After collecting cancerous samples and DNA extraction from blood samples of normal and patients, change in the miRNA binding region by digestion with NlaIII enzyme was assayed.
Results: Bioinformatics studies showed that the restriction site of some of the endonuclease enzymes in the 3'-UTR of the TYMS gene is related to the binding region of miRNAs, including Hsa-miR-433-3p. The results indicated the correctness of the genomic purification process, the PCR and enzymatic digestion reaction. In this study, in the regulatory region, CC homozygote, AC heterozygote and AA mutant homozygote variant had differences with control group (OR: 1.3465, %95 CI: 0.7275 to 2.4923, p<0.05). Also, the association of AA genotypes with metastasis and high grade of the patients was confirmed statistically.
Conclusion: Studies have shown that some of polymorphisms in the key genes involved in cancer are directly related to their diagnosis and treatment process, and given the importance of timely diagnosis of cancer, the achievement of diagnostic biomarkers in breast cancer in the early stages will be important. Probably, the nucleotide change at the site of the microRNA binding site could be used as a diagnostic biomarker for degree of tumor progression.

Abstract
Background and Aim: The long noncoding RNAs (lncRNAs) is an important type of RNAs that can regulate gene expression and, therefore, are involved in the development of various cancers. The genome-wide association study (GWAS) is used to identify phenotype-related loci within non-coding regions. However, the biological functions and exact relationships between phenotype-related loci and lncRNAs have not fully been identified. No study was found on the relationship between rs8506C>T polymorphisms in the lincRNA-NR_024015 exon and breast cancer susceptibility and clinical factors. Therefore, the present study aimed to evaluate the effect of polymorphism rs8506C>T on the breast cancer risk.
Methods & Materials: In this case-control study, participants were 120 patients with breast cancer, 120 healthy controls. The genetic variant was genotyped by using the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR–RFLP) method. Interactions between the polymorphism and clinical factors were further evaluated, and Odds Ratio (OR) was measured for risk assessment.
Ethical Considerations: This study has been approved by the Research Ethics Committee at Shahrekord University of Medical Sciences (code:????) .
Results: There was a correlation between rs8506 C>T polymorphism and breast cancer risk in the dominant model (CC and CT+TT genotypes; P=0.027; OR=1.84; 95% CI: 1.067‐3.201). In the co-dominant model, CT genotype had a statistically significant association with breast cancer risk (P=0.038). Subjects with T allele in the rs8506 polymorphism had an increased risk of breast cancer (OR=1.69; 95% CI: 1.047-2.736; P=0.031). No relationship between rs8506 polymorphism and clinical factors including metastasis, tumor grade, and Human Epidermal Growth Factor Receptor 2 (HER2) status was observed.
Conclusion: Genetic variant rs8506 C>T polymorphism in the lincRNA-NR_024015 exon may contribute to the breast cancer risk. Allele T in this variant confers an increased risk of breast cancer. Further functional analyses are required to detect the detailed mechanism underlying the observed association.

Abstract
Background and Aim: Breast cancer is the abnormal cell growth in the breast. In both benign and malignant masses, there is rapid and high cell growth. Nowadays, due to the development of technologies, the diagnosis of diseases has become non-invasive and physicians attempts to diagnose the disease without surgery and based on internal organ images.
Methods & Materials: In this study, by using images prepared from the Digital Database for Screening Mammography (DDSM), a new method is proposed for detecting cancerous masses in the mammographic images using geometric features extraction and optimization of Support Vector Machine (SVM) parameters to classify breast cancer masses automatically. First, images were pre-processed and then boundaries were determined using threshold method. Next, morphological operators were used to improve these boundaries and the segmentation of images was carried out to classify cancerous masses. Finally, by using the SVM parameter optimization method, Grasshopper Optimization Algorithm (GOA), and 4-fold crossvalidation method, data were classified into two groups of benign and malignant (cancer) masses.
Ethical Considerations Images from DDSM database were used in this research, all images are open access in this database.
Results: The accuracy, sensitivity and specificity values for applying the Radial Basis Function (RBF) kernel in SVM classifier (before optimization process) were obtained 97%, 100% and 96, respectively. After optimization of SVM parameters by the GOA, it was reported 100% for all accuracy, sensitivity and specificity indices for applying linear kernel function, indicating the high accuracy of the proposed method. The average values of accuracy, sensitivity and specificity indices for applying all three SVM kernel functions after optimization were 95.83, 100 and 94.81%, respectively.
Conclusion: The extracted geometrical features from breast cancer masses are highly efficient for model training and the diagnosis of breast cancer. The GOA could improve the overall accuracy of the proposed method by optimizing the SVM parameters. The results showed the higher performance of the proposed method compared to other methods.

Abstract
Background and Aim: Breast cancer is the most common cancer type and the leading cause of cancer-induced deaths in women, worldwide. The Fibroblast Growth Factor Receptor 2 (FGFR2) is a tyrosine kinase receptor that plays an essential role in the growth, invasion, movement, and angiogenesis of tumor cells. Several single nucleotide polymorphisms have been found in the intron 2 of the FGFR2 gene, i.e., associated with a high risk of breast cancer. Genetic variation in this receptor is a new risk factor for breast cancer. The current study aimed to evaluate the association of single-nucleotide polymorphism rs2981582C/T in women with breast cancer.
Methods & Materials: In total, 80 women with breast cancer and 80 healthy women (controls) were selected from Markazi Province, Iran to participate in this research. Polymorphism rs2981582 was analyzed to investigate its association with breast cancer. DNA extraction from blood samples was performed using a kit. The presence of these single-nucleotide polymorphisms was determined by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR - RFLP). Statistical analyses were performed by SPSS using Chi-squared test at P≤0.05.
Ethical Considerations: This study was approved by the Ethics Committee of the Arak University (Code: IR.ARAKMU.REC.1395.28).
Results: Significant differences were observed in the frequency of rs2981582 polymorphism in the FGFR2 gene between the control and patient groups (P=0.000). In the patient group, the TT genotype was significantly associated with the risk of breast cancer (P=0.001; OR=3.566). On the other hand, allele C indicated a protective role against the disease (P=0.000).
Conclusion: The obtained data revealed a significant relationship between rs2981582 C/T polymorphism and the risk of breast cancer; thus, this single-nucleotide polymorphism could be used as a biomarker to predict breast cancer.

Abstract
Background and Aim: Breast cancer is among the most prevalent cancers in women with extensive associated biopsychological problems. The present study aimed to determine the effects of holographic reprocessing therapy on cognitive flexibility and posttraumatic growth in women with breast cancer.
Methods & Materials: This was a quasi-experimental study with pretest-posttest and a control group design. The statistical population included all patients with breast cancer who underwent mastectomy and who were being treated in the chemotherapy ward of Imam Khomeini Hospital in Ardabil City, Iran, in 2020.
By convenience sampling method, 30 women with breast cancer were selected and randomly divided into the experimental and control groups (n=15/group). The experimental group, while receiving pharmacotherapy, collectively underwent holographic reprocessing therapy in 9 one-hour sessions (two sessions per week) for 5 weeks; however, the control group received only pharmacotherapy. Both research groups were assessed in pretest and posttest phases by the Cognitive Flexibility Inventory (Dennis & Vander Wal, 2010) and the Posttraumatic Growth Inventory (Tedeschi & Calhoun, 1996). Finally, the obtained data were analyzed using Multivariate Analysis of Covariance (MANCOVA) in SPSS v. 23.
Ethical Considerations: All study subjects provided a signed written informed consent form. The Research Ethics Committee of Ardabil University of Medical Sciences approved this study (Code: IR.ARUMS.REC.1399.393).
Results: The current study results indicated that holographic reprocessing therapy was effective on cognitive flexibility (F= 42.319, P<0.01) and posttraumatic growth (F= 18.300, P<0.01) in women with breast cancer; this method also increased their cognitive flexibility and posttraumatic growth.
Conclusion: Considering psychological factors and information processing methods in patients with cancer is highly important. Thus, counselors and psychotherapists are advised to use holographic reprocessing therapy as a complementary treatment without adverse effects along with medical treatments to reduce the psychosocial problems caused by the disease.

Abstract
Introduction: Breast cancer is a highly heterogeneous disease. The antigen molecule of four cytotoxic T-lymphocytes is involved in inhibition of T cell response and immune response regulation. Single nucleotide polymorphisms in the CTLA4 gene can affect the expression of the aforementioned molecule. The aim of this study was to investigate the polymorphisms of rs4553808 and rs733618 of CTLA4 gene with the risk of breast cancer.
Methods: In this study to investigation polymorphisms, the DNA of 80 patients with breast cancer and 80 healthy individuals in central province of ARAK were extracted from peripheral blood. Then, PCR-RFLP technique was used. The results were analyzed using SPSS software and SNP Analyzer. This study was approved by the Ethics Committee of the Arak University (Code: Ir.arakmu.rec.1396.25).
Results: Statistical analysis rs4553808 polymorphism showed no significant increase in the risk of patients with GG genotype compared with the control group (OR = 2/013, CI = 95% 1/721-2/353). Also, heterozygotes AG genotype analysis did not show any relationship between the genetic diversity and breast cancer (OR = 1/204, CI = 95% 0/604-2/402). The combination of AG + GG genotypes did not show any significant correlations (OR = 1/130, CI = 95% 0/569-2/242). Statistical analysis for rs733618 polymorphism showed increase in the risk of breast cancer. The results indicate that the TC (OR = 2/992, CI = 95% 1/280-1/998) showed a significant relationship between the genetic diversity and breast cancer. The analysis of the combined CC and TC genotypes was associated with increased risk for breast cancer compared to TT genotypes (OR = 0/334, CI = 95%; 0.143-0.782, P = 0.009). Considering that the distribution of CC and TC genotypes was significant between the two groups of control and the patient, so the frequency of TT genotype with the same amount of P = 0.001 was significant between the two groups of control and the patient.
Conclusions: There was a significant relationship between the genotypes rs733618 polymorphism and breast cancer. However, there was no significant relationship between rs4553808 polymorphism and breast cancer risk.

Abstract
Introduction: Breast cancer causes psychological problems and decreases psychological health in people, therapeutic interventions are needed to solve these problems. This research was conducted to determine the effectiveness of group meaning therapy intervention on the quality of life, emotional regulation, and life expectancy of women with breast cancer.
Methods: The research method was semi-experimental with a pre-test-post-test design with a control group. The statistical population included all women with breast cancer referring to the health centers of Kerman city in 2023. Among them, 30 people were selected by the available sampling method and were replaced randomly and by lottery in two experimental and control groups (15 individuals in the experimental group and 15 in the control group). The people in the experimental group received group-meaning therapy intervention (10 sessions) and two sessions weekly for 90 minutes. The questionnaires used in this research included quality of life, emotion regulation, and life expectancy questionnaires administered in two phases: pre-test and post-test.
Results: The results showed that before the intervention, there was no significant difference between the average scores of the quality of life, emotion regulation, and life expectancy of the intervention and control groups, but there was a statistically significant difference between the average scores of the intervention and control groups after the intervention. The mean and standard deviation of the quality of life in the post-test was 6.91 ± 29.75, emotion regulation was 10.25 ± 98.28, and life expectancy was 6.49 ± 39.51 (P < 0.001).
Conclusions: According to the results of this research, group therapy increased the quality of life, emotion regulation, and life expectancy in women with cancer. Since the favorable mental state of the patient affects their recovery, the use of this method is recommended as an effective strategy to reduce the psychological problems of patients.

Introduction: The present study was conducted to analyze the focal relationship of the contribution of mental adaptation to cancer, health literacy, and perceived threat in predicting the early diagnosis of breast cancer.
Methods: This study was a descriptive correlational research. The statistical population of the present study included all women with breast cancer under treatment at Shohadaye Tajrish Hospital Cancer Treatment Center in 2023, and 310 people were determined to participate in the research using G*Power software and the available sampling method. They responded to Williams, Templin, and Hines's breast cancer literacy questionnaires, Champion's perceived threat questionnaire, Watson's mental adaptation to cancer and early diagnosis questionnaire. The data were also analyzed using a focal correlation test and multiple regression.
Results: The results showed that there is a significant relationship between the contribution variables of mental adaptation, perceived threat, and health literacy with the components of early cancer diagnosis (knowledge, attitude, and actions) (P ≤ 0.01). Also, the results showed that health literacy was 4.8%, mental compatibility was 3.4 percent and perceived threat 18.7% alone predicted the variance of early diagnosis of breast cancer. The perceived threat share is 38.9%, higher than all other variables.
Conclusions: Based on the statistical results, it can be said that increasing mental adaptability, perceived threat, and health literacy play a role in early disease diagnosis, and the importance of perceived threat is more significant than mental adaptability and health literacy, which should be considered.
