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: Cervical Cancer (CC) is the third most common malignancy in the women, the main cause of which is human papillomavirus (HPV). Both E6 and E7 oncogenes of the virus play an important role in its tumorigenesis. Today, methods available for screening CC are not capable of detecting the disease at an early stage. Therefore, it is important to identify new biomarkers for early detection of this cancer. For this purpose, in the present study, miRNAs targeting the two oncogenes E6 and E7 of human papillomavirus (types 16 and 18) were studied in CC by bioinformatics.
Methods & Materials: First, using the NCBI database, the E6 and E7 gene sequences were obtained for both human papillomavirus types 16 and 18. Then, using the miRBase and RNA22 bioinformatics databases, the most appropriate targeting miRNAs for these genes were selected.
Ethical Considerations: This study was approved by Ethics Committee of Arak University of Medical Sciences.
Results: Based on the P obtained from bioinformatics databases, miRNA including miR-92a-5p (P=7.51e-2), miR-195-3p (P=2.24e-1), miR-34a-5p (P=2.73e-1) and miR-155-5p (P=4.95e-2) were introduced for the two genes E6 and E7.
Conclusion: Results from bioinformatics studies revealed that of the four miRNAs identified, miR-155-5p and miR-92a-5p are probably the targeting miRNAs specific for the E6 and E7 genes, respectively. Therefore, it seems that these miRNAs can be a suitable candidate for in vitro studies in CC patients.

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: Despite the anti-cancer and antimicrobial properties of licorice extract and lavender essential oil, some factors, such as low bioavailability and biodegradable, limit their therapeutic use. Using nanoparticles is a method to overcome these restrictions. This study aimed to investigate the anti-proliferative effects of nanoemulsion containing licorice extract and lavender essential oil on cancer cells; we also evaluated its antimicrobial properties in vitro.
Methods & Materials: In this experimental study, nanoemulsions, containing licorice extract and lavender essential oil were developed by the spontaneous emulsion method. The anti-proliferative effect of nanoemulsion was investigated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) colorimetric method on two cell lines HepG2 and SK-MEL-3. To measure the antimicrobial effect of 4 standard strains of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus epidermidis, and Minimum Inhibitory Concentration (MIC) method was used.
Ethical Considerations: This study was approved by the Ethics Committee of Kashan University of Medical Sciences (Code: IR.KAUMS.MEDNT.REC.1396.106).
Results: The results of MTT test on HepG2 cells indicated that the concentrations of 630, 1250, and 2500 μg/mL nanoemulsions caused toxicity to the cell and led to the death of >50% of the cells (IC50=401μg/mL; P<0.05). Evaluating SK-MEL3 cells revealed that except for 75 μg of nanoemulsion, other concentrations induced death in >50% of the cells (IC50 = 82 μg/mL; P<0.05). In addition, nanoemulsions, with antimicrobial properties, were studied in 4 strains of bacteria; the highest antimicrobial properties were observed in Staphylococcus epidermidis.
Conclusion: Nanoemulsion containing licorice extract and lavender essential oil presents antimicrobial and antiproliferative effects on the two cell lines studied. The current study results indicated that the nano emulsification of lavender essential oil and licorice extract can enhance their biological impact; thus, they can be used as a drug formulation.

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
Background and Aim: Ovarian cancer is among the most common cancers in women worldwide. CA125 is the most frequent biomarker used in the screening for ovarian cancer. CA125 has no high sensitivity and specificity as a screening test in the medical community; however, because of being simple and noninvasive, it is almost always requested for evaluation and ruling out cancer. It plays an important role in the treatment and post-treatment process, the prediction of prognosis, and the relapse of the disease. The present study aimed to determine the relationship between a high level of CA125 tumor marker and ovarian cancer by detecting spesivity, sensivity, positive and negative predictive values.
Methods & Materials: In this cross-sectional study, all cases undergoing CA125 test in Velayat Hospital in
2017-1028 were evaluated for having ovarian cancer. In addition, the CA125 level was compared between healthy individuals and patients with ovarian cancer. Finally, the obtained data were analyzed using SPSS.
Ethical Considerations: The present study was approved by the Qazvin University of Medical Sciences (Ethics Code: IR.QUMS.REC.1396.316).
Results: In this study, 35.3% of the study participants received a definite diagnosis of ovarian cancer. Generally, CA125 values were negative in 41.8% and positive in.58.2% of the study subjects. The sensitivity of the test was measured as 80.1%, the specivity as 53.6%, the positive predictive value equaled 48.4%, and the negative predictive value was measured as 83%. There was a significant relationship between age and the presence of ovarian cancer, and serum CA125 levels.
Conclusion: The present study suggested that age and the serum level of CA125 were statistically significant. Finally, CA125 levels were significantly related to ovarian cancer. It provided moderate specivity and specivity as well as low positive predictive value and high negative predictive value as a tumor marker; it is valuable for ruling out of tumor but not appropriate as a screening test.

Abstract
Background and Aim: The protein encoded by the SGO1 gene is a member of the shugoshin family of proteins and protects the centromere during mitosis. lncRNAs are non-coding RNA with 200 nucleotides lengths, i.e., involved in regulating gene expression. The current study aimed to evaluate the expression of SGO1 and SGO1-AS1 in different stages of disease progression; we also compared their expression pattern in tumor tissues with healthy tissues in colorectal cancer patients.
Methods & Materials: In total, 40 tissue samples of patients with colorectal cancer were reported according to the examination and criteria with the approval of a pathologist. Besides, 40 normal tissues were sampled from a completely healthy part of the intestine of the same patients. After RNA extraction and cDNA synthesis, the Real-time RT-PCR technique was used to evaluate the expression of the desired genes in the study groups. ROC curve analysis was also used to determine the ability of each selected gene to diagnose the disease.
Ethical Considerations: This study was approved by the Ethics Committee of Shahrekord Azad University (Code: IR.IAU.SHKREC.1398.020).
Results The obtained data suggested that SGO1 significantly decreased in the colorectal cancer tumor samples (P<0.001) and SGO1-AS1 LncRNA significantly increased expression, compared to adjacent healthy tissues. Additionally, in the age group of below 60 years, compared to the age group of over 60 years, SGO1 expression increased and SGO1-AS1 expression decreased. Based on the AUC obtained from the ROC diagram, it was found that the SGO1 gene with AUC=0.8041 and SGO1-AS1 with AUC=0.6364 could significantly distinguish a healthy population from patients with colorectal cancer.
Conclusion: According to the collected results, SGO1 -AS1 and SGO1 were significantly reduced and increased in tumor tissue, respectively; however, only the SGO1 gene was introduced as a good marker for diagnosing colorectal cancer.

Abstract
Background and Aim: Cancer cannot be explained only by genetic alterations but involves epigenetic processes. Modifying histones by acetylation plays a key role in epigenetic regulation of gene expression and is controlled by the balance between Histone Deacetylases (HDAC) and Histone Acetyltransferases (HAT). The HDACs expression and activity could be involved in several tumorigenesis mechanisms, so their inhibition induces cancer cell cycle arrest and migration.
Methods & Materials: Quisinostat is a novel promising second-generation HDAC inhibitor class of hydroxamic acid with high cellular potency towards classes I and II HDACs. Therefore, its low IC50 (<0.5nM) and bioavailability have been chosen to carry out our studies. Cancer cells were treated with Quiznos at nM200, and cell migration was measured by fluorescent microscopy.
Ethical Considerations: This study was the result of a preliminary study of Shiraz University (Code: 96GCU3M1293).
Results: The data showed that treatment of cancer cells with Quiznos significantly (P<0.05) reduced cell migration. DMSO did not affect reducing cell migration.
Conclusion: In this project try to explore the possible therapeutic application of this HDAC inhibitor against colon cancer. This study showed Quisinostat exerts broad-spectrum antiproliferative activity and migration.

Abstract
Background and Aim PBK is a mitogen-activated protein kinase (MAPKK) among MEK1/2 and MEK7 and can phosphorylate P38, JNK, and ERK in many cellular functions. The E2F transcription factor family also belongs to a class of cellular regulators acting as oncogenes and tumor suppressors. This study aims to investigate the expression of PBK and E2F7 in the early stages of colorectal cancer (CRC) compared to advanced stages based on the experimental and TCGA (The Cancer Genome Atlas) database.
Methods & Materials A total of 32 tissue samples of patients with CRC with the approval of a pathobiologist were collected according to the examination and criteria reported from different stages. After RNA extraction and cDNA synthesis, the RT-qPCR technique was used to evaluate the expression of the desired genes in the study groups. A receiver operating characteristic (ROC) curve analysis was also used to determine the ability of each of the selected genes to differentiate the two populations: stage I+II and stage III+IV.
Ethical Considerations In all stages of this research, codes of ethics of research and publication were observed.
Results In this study, it was shown that the expression of PBK and E2F7 significantly increased in stage I+II samples compared to stage III+IV. These data were confirmed by laboratory results and information extracted from the TCGA database. Also, based on the area under curve obtained from the ROC curves, these two genes are significantly distinguishable between stage I+II and III+IV populations in CRC.
Conclusion According to the results of this study, PBK and E2F7 genes are good markers in the diagnosis of CRC.

Abstract
Background and Aim MicroRNAs (miRNAs) are a class of small non-coding RNAs (17-25 nucleotides) that have been studied in many diseases. miRNAs studies in different cancers have shown that miRNAs may be considered oncogene or tumor suppressor. So far, many studies have shown that miR-17-5p and miR-93-5p are important regulatory molecules in some biological processes, such as cell proliferation, associated with cancer formation. This study aimed to investigate and compare the tissue and plasma expression levels of miR-17-5p and miR-93-5p in patients with ductal carcinoma breast cancer with the normal control group.
Methods & Materials The total RNA (including miRNA) was extracted from breast and plasma tissue samples of cancerous and normal samples. The RNA concentration and purity were confirmed using optical absorbance measurements. cDNA was synthesized, and the expression levels of miR-17-5p and miR-93-5p were assessed semi-quantitatively by SYBR Green-based real-time RT-PCR assay in plasma and breast tissues of ductal carcinoma breast cancer compared with the control normal samples with SNORD47 as internal normalizer. Data were statistically evaluated using GraphPad Prism 8.0.2.
Ethical Considerations This study was approved by the Ethics Committee of the institute (IRAN 52d/4922, 6.10.2016). All study individuals signed a consent form to use their clinical samples and personal data under the physician’s supervision.
Results The expression level of miR-17-5p showed significantly higher expression in tissues and plasma of the cancer group compared with the control group (P<0.0001). It was also significantly associated with tumor stage and lymph node, and ER (estrogen receptor) and PR (progesterone receptor) status (P<0.0001). While decreased expression of miR-93-5p in plasma and tumor tissues was shown to be significantly associated with tumor stage and lymph node involvement (P<0.0001).
Conclusion The data revealed that high expression of miR-17-5p and low expression of miR-93-5p in both plasma and breast tumor might be associated with poor prognosis in breast cancer. However, miR-17-5p, due to the greater change in expression and ease of plasma detection, may serve as a possible non-invasive biomarker for breast cancer’s poor prognosis. Further follow-up studies are required to confirm this finding.

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.

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.

Abstract
Introduction: Bird′s-foot trefoil (Lotus corniculatus L., Fabaceae) has many medicinal properties due to its valuable chemical compounds. This research reviews the chemical compounds and medicinal properties of this plant.
Methods: This study used library resources, search engines, and databases such as Google, Google Scholar, PubMed, PubChem, ScienceDirect, Magiran, ResearchGate, and SID. The data were collected and classified.
Results: The results indicate that bird′s-foot trefoil is rich in valuable compounds such as kaempferol, quercetin, isorhamnetin, oleamide, and linoleamide. Different extracts of this plant have antioxidant, anti-inflammatory, immunostimulant, anti-cancer, anti-pain, anti-depressant, anti-amylase, anti-fungal, antiprotozoal, and anti-bacterial activities. It is used for wound healing, controlling anxiety and nausea, treating urinary infections, removing kidney stones, and as an antispasmodic and anti-hemorrhoid. Topical application of Lotus corniculatus seed extract has reduced the sebum contents and areas of oily human skin.
Conclusions: L. corniculatus can directly and indirectly affect human life and health. Due to the effective compounds and medicinal properties of Bird′s-foot trefoil, additional studies and clinical tests on its medicinal properties should be performed.

Abstract
Background: Thyroid cancer is one of the most common types of endocrine malignancies. FASL is one of the most important apoptosis ligands expressed by tumor-infiltrating lymphocytes. This death ligand plays an important role in the elimination of cancer cells by inducing apoptosis in the Fas/FasL pathway, and its disruption induces tumorigenesis. This study investigated the association of the FASL gene polymorphism - INV2nt-124A/G (rs5030772) with the risk of thyroid cancer in the East Azerbaijan region.
Materials and Methods: In this case-control study, 115 patients with thyroid cancer and 125 healthy individuals without a family history of cancer from Tabriz city were studied. Five milliliters of peripheral blood were collected from each of these participants. Proteinase K method was used for DNA extraction and FASL gene polymorphism (rs5030772) was analyzed by ARMS-PCR technique. The results were analyzed using Javastat statistics package online software.
Results: The genotype frequencies of AA, AG and GG were 40.35%, 49.12% and 10.53% in patients and 41.6%, 52.8% and 5.6% in the control group, respectively. Genotypic and allelic frequencies did not show significant differences between the patient and control groups (p>0.05). By examining the clinicopathological characteristics of the patients, no significant relationship was seen between the clinical characteristics of the patients and the distribution of the genotypes of this polymorphism (p<0.05).
Conclusion: The results of this study indicate that the FASL gene polymorphism - INV2nt-124A/G (rs5030772) cannot be considered as a risk factor for thyroid cancer in the studied population in in East Azerbaijan province.
