Abstract
Circular RNAs (circRNAs) characterize a novel kind of regulatory RNAs distinguished by great evolutionary conservation and constancy. Although their exact role in malignancies is not fully understood, they mainly work through specific axes. Circular RNA/miRNA/mRNA axes affect the pathogenesis of human cancers including breast cancer. We assessed the expression and function of circ_0009910/miR-145-5p/MUC1 axis in Breast Cancer tissues and MCF-7 cells. Expression levels of circ_0009910 and MUC1 were notably increased in breast cancer tissues compared with control tissues, parallel with the down-regulation of miR-145-5p. Clinicopathological analysis indicated that up-regulation of circ_0009910 in breast tumors is related to invasion of the tumor to lymph node (P value = 0.011). Also, the downregulation of miR-145-5p was significantly correlated with tumor invasion to lymph nodes (P value = 0.04) and HER2-negative tumors (P value = 0.037). Finally, overexpression of MUC1 was correlated with age under 45 years (P value = 0.002). More importantly, circ_0009910-siRNA decreased the proliferation and migration ability of breast cancer cells, enhanced expression of miR-145-5p, and decreased levels of MUC1. Taken together, the circ_0009910/miR-145-5p/MUC1 axis has been demonstrated to affect the pathogenesis of breast cancer and might provide a target for breast cancer treatment.

Abstract
Background:
Breast cancer is one of the most common cancers. Researchers are trying to diagnose the disease through easier and safer methods. Serum markers such as ferritin and vitamin D level would be very helpful. This research could pave the way for more comprehensive studies on how to use this serum factor in breast cancer screening, as well as early detection of the disease in its early stages. Methods:
This study consisted of two groups, the first group comprising patients diagnosed with breast cancer before undergoing any treatment and the second group as control were healthy people. Serum ferritin and vitamin D levels were measured. Pathological information of the patient's tumor, including ER, HER2, KI67, lymphovascular invasion, and disease stage, were collected as well. Data were analyzed by IBM SPSS advanced statistics version 23.0 (SPSS Inc., Chicago, IL). P-value of ≤0.05 was considered significant. Results:
Eighty-eight subjects were enrolled in this study, 29 (33%) breast cancer patients and 59 (67%) healthy women. In breast cancer patients, serum ferritin levels were 106.55±111.25, which were higher than healthy women’s serum ferritin 52.71±36.95 (p=0.083). Furthermore, 18 (66.7%) of breast cancer patients and 55 (93.2%) of healthy women had low serum ferritin levels (p=0.001). 3 (11.1%) patients in the cancer group had serum vitamin D deficiency, while all subjects in the control group had serum vitamin D higher than 10 ng/dl (p =0.009). Conclusion:
The results of this study showed a correlation between breast cancer and vitamin D deficiency, and elevated ferritin. Perhaps with further studies, there could be a role in predicting the prognosis and screening of breast cancer for these associations.

Abstract
Background: Long non-coding RNAs (LncRNAs) are eminent genes in the human genome that interfere with the regulation of many complexities of organisms and control many of the various biological processes. As a result, it is considered that they may play an important role in different cancers. With regard to the high prevalence of breast cancer and the role of lncRNA, the present study aimed at investigating the expression of various lncRNAs.
Method:
Fresh tissues were obtained from operating rooms of Shariati, Khatamolanbia, and Milad Hospitals (Tehran, Iran) by a surgeon. A total of 45 tumor samples and 45 non-tumor samples (from the margin of tumor) were obtained from the same patients. Relative expression evaluation method was used in Real time PCR. Estrogenn receptor (ER), progesterone receptor (PR), and HER2 expression were analyzed using IHC analyses of each cell block.
Results: Participants included 44 female and 1 male with the mean age ± SD of 50 ± 12.0 years (range: 23-74). A majority of participants (41/45) were Ductal carcinoma type. Our results showed significant expressions for CBR3-AS1 (P-value=0.0139), RAB6C-AS1 (P-value=0.0023), and ZEB2-AS1 (P-value=0.0289) in comparison with the healthy cells. ROC curve analysis for CBR3-AS1 LncRNA revaled sensitivity more than 70%.
Conclusion: Although CBR3-AS1, RAB6C-AS1, and ZEB2-AS1 lncRNAs were found to have high expressions in the breast cancer cells, only CBR3-AS1 lncRNA has a high chance to be a breast cancer biomarker.

Abstract
BACKGROUND Sentinel lymph node biopsy is a reliable method for evaluation of the axillary lymph node status in early stage breast cancer patients with non-palpable lymph nodes. The present study evaluated the status of sentinel and non-sentinel lymph nodes in T1T2 patients with palpable axillary lymph nodes. MATERIALS AND METHODS One hundred and two women with early breast cancer were investigated in this study. Patients were selected for axillary sentinel lymph node biopsy and then surgery .Then the rates of false negative and true positive, and diagnostic accuracy of sentinel lymph nodes biopsy were evaluated. In addition, the hormone receptors status of the tumor was determined through IHC and data was analyzed in SPSS21. RESULTS In this study, the mean age of the patients was 49 years, 85% had invasive ductal carcinoma in their pathology reports, 77% were ER/PR positive, 30% HER2 positive and 9.8% triple negative and 69% had KI67<14%. In frozen pathology, 15.7 and 84.3% were sentinel positive and negative, respectively, and in the final pathology, 41 and 58.8% were sentinel positive and negative, respectively. This difference arises from the false negative rate of the frozen pathology, which was about 31.3%. The sensitivity, specificity, and diagnostic accuracy of the frozen section were 24, 90 and 43%, respectively. Lymphovascular invasion is an important effective factor in the involvement of sentinel and non-sentinel lymph nodes. Statistical analysis showed that the probability of sentinel and non-sentinel lymph nodes involvement was higher in receptor positive patients and those with KI67>14% (p<0.002) whereas the rate of involvement was lower in triple negative patients. CONCLUSION Sentinel node biopsy can be used in a significant percentage of breast cancer patients with palpable and reactive axillary lymph nodes.

Abstract
AIM Intraoperative electron Radiotherapy, herein referred to, as IOeRT is a novel approach in breast cancer (BC) treatment. This study designed to investigate short-term molecular effects of 12Gy as Boost versus 21Gy as Radical dose of IOeRT using high throughput approaches. MATERIALS AND METHODS Six BC patients as a pilot study were treated with IOeRT following two separate strategies, including Boost and Radical doses. Approximately 100 mg of tumor bed tissue retrieved from each patient (before IOeRT,immediately, 24 h post-treatment). mRNA sequencing also Isobaric tag for relative and absolute quantitation (iTRAQ) were performed to study the transcriptome and proteome profile of IOeRT-treated tumor bed. RESULTS Using NGS, ~6 Giga base (GB) clean data per individual samples were generated. Moreover, by iTRAQ for proteome quantification, in total, 1,045,410 spectrums were generated, likewise 5860 proteins were identified (FDR <0.01). CONCLUSION Functional annotation and gene ontology (GO) indicated that significant enrichment in molecular pathways on BC treatment is somehow single high dose-independent. This means that, key molecular pathways in radiotherapy (RT) are equally enriched by both Boost and Radical doses. Generally, by modification of the Radical dose, with the same effectiveness, it is possible to reduce single high dose irradiation in BC.

Abstract
Background: Breast cancer is a hormone-dependent malignancy that is associated with estrogen and progesterone interactions. The liver is the most important organ to be affected by the metastasis of breast cancer, which causes functional impairment.
Aim: We compared levels of obesity, 17β-estradiol, and secreted proteins in postmenopausal women with breast cancer but without hepatic symptoms to those in healthy postmenopausal women.
Materials and Methods: We recruited 105 postmenopausal women with breast cancer but without any clinical hepatic symptoms based on a physician’s diagnosis, and 105 healthy postmenopausal women. After taking blood samples, we separated the serum and determined the levels of alanine aminotransferase (ALT), enzyme aspartate aminotransferase (AST), sex hormone-binding globulin (SHBG), and 17β-estradiol using an enzyme-linked immunosorbent assay (ELISA). The results were statistically analyzed using SPSS.
Results: The mean ages of the subjects in the cancer and control groups were 60.88 ± 0.85 and 55.56 ± 0.81 years, respectively. The exception ages (p=0.002), body mass index (BMI) values (p=0.033), serum glutamic oxaloacetic transaminase (SGOT) levels/AST levels (p=3.1*10−4), serum glutamic pyruvic transaminase (SGPT) levels/ALT levels(p=0.001), SHBG levels(p=0.014), and 17β-estradiol levels(p=0.003) in the serum differed significantly between the groups. Moreover, the mean serum 17β-estradiol (E2) levels and weights were higher in the cancer group than in the control group. Nevertheless, the mean serum levels of synthetic liver enzymes (SHBG, ALT, and AST) were lower in the cancer group than in the control group.
Conclusion: In general, the postmenopausal cancer patients had higher serum estrogen levels and BMIs than their healthy counterparts. Furthermore, the levels of liver enzymes apparently decreased in the cancer group, probably owing to liver malfunction.

Abstract
This study aimed to measure the received dose to the pelvic region of patients during breast intraoperative electron radiation therapy (IOERT). Furthermore, we compared the findings with those of external beam radiation therapy. Finally, secondary ovarian and uterus cancer risks following breast IOERT were estimated. In the current study, the received dose to the pelvic surface of 18 female patients during breast IOERT boosts were measured by thermoluminescent dosimeter (TLD-100) chips. All patients were treated with 12 Gy given in a single fraction. To estimate the dose to the ovary and uterus of the patients, conversion coefficients for depth from the surface dose were obtained in a Rando phantom. Given the received dose to the pelvic region of the patients, secondary ovarian and uterus cancer risks following breast IOERT were estimated. The received doses to the ovary and uterus surface of the patients were 0.260 ± 0.155 mGy to 31.460 ± 6.020 mGy and 0.485 ± 0.122 mGy to 22.387 ± 15.476 mGy, respectively. Corresponding intra-pelvic (ovary and uterus) regional doses were 0.012 ± 0.007 mGy to 1.479 ± 0.283 mGy and 0.027 ± 0.001 mGy to 1.164 ± 0.805 mGy, respectively. Findings demonstrated that the ratio of the received dose by the pelvic surface to the regional dose during breast IOERT was much less than external beam radiation therapy. The mean of the secondary cancer risks for the ovary in 8 and 10 MeV electron beam energies were 135.722 ± 117.331 × 10-6 and 69.958 ± 28.072 × 10-6, and for the uterus were 17.342 ± 10.583 × 10-6 and 2.971 ± 3.604 × 10-6, respectively. According to our findings, the use of breast IOERT in pregnant patients can be considered as a safe radiotherapeutic technique, because the received dose to the fetus was lower than 50 mGy. Furthermore, IOERT can efficiently reduce the unnecessary dose to the pelvic region and lowers the risk of secondary ovarian and uterus cancer following breast irradiation.

Abstract
Hermaphroditism is known as ovotesticular disorder of sex development. A 14-year-old boy was admitted with right acute scrotum. Exploration revealed tunica rupture and hematoma, with no viable tissue. After 1 month, he was admitted again with left hemiscrotal pain. Microscopic examination of the left gonad demonstrated foci of hemorrhagic cysts, primordial follicles, and regions of seminiferous tubules. We preserved a testicular tissue and the ovarian part was extracted completely. Long-term follow-up with his hormonal profile is reported. This is a case of ovotesticular disorder presented with acute scrotum and we also tried to reduce long-term hormone therapy, with preservation of testicular part.

Abstract
BACKGROUND The use of acellular dermal matrices (ABDM) has become more common for breast reconstruction to improve postoperative outcomes. We evaluated the efficacy of breast reconstruction by the application of human ABDM in a sheep model. METHODS The sheep in group I (GI) (N = 4) underwent the following procedures on the right side: (1) breast reconstruction using human ABDM after total mastectomy, (2) human ABDM under the skin, near the breast area and on the left side, (3) fat injection and human ABDM after partial mastectomy, and (4) replacement of ABDM in the abdominal wall far from the breast. Sheep in group II (GII) (N = 4) underwent the following procedures. On the right side: (1) breast reconstruction using ABDM after total mastectomy, (2) replacement of ABDM under the skin, near the breast area, and on the left side, (3) application of vicryl synthetic mesh after partial mastectomy and (4) replacement of mesh under the skin, near the breast area. RESULTS Histological evaluations of decellularized skin scaffolds demonstrated a collagen-based matrix with preserved ECM and complete nuclear removal. Histological evaluations of implanted ABDM demonstrated a viable matrix with fibroblast infiltration and revascularization in all follow-ups. The overall surgical complication rate was significantly lower in the ABDM implant under the skin and near the breast in both short- and long-term follow-ups. CONCLUSION The results of this study demonstrated that the application of novel prepared ABDMs has promising outcomes for breast reconstruction to provide total coverage without the need for breast expansion before implant placement.

Abstract
INTRODUCTION Sentinel lymph node biopsy (SLNB) is a precise procedure for lymphatic staging in early breast cancer. In a valid SLNB procedure, axillary lymph node dissection (ALND) can be omitted in node- negative cases without compromising patient safety. In this study, detection rate, accuracy and false negative rate of SLNB for breast cancer was evaluated in a setting with simple modified conventional pathology facilities without any serial sectioning or immunohistochemistry. MATERIAL AND METHOD Patients with confirmed breast cancer were enrolled in the study. SLNB and ALND were performed in all cases. Lymph node metastasis was evaluated in SLN and in nodes removed by ALND to determine the false negative rate. Pathologic assessment was carried out only by modified conventional technique with only 3 sections. Detection rate was determined either by lymphoscintigraphy or during surgery. RESULTS 78 patients with 79 breast units were evaluated. SLN was detected in 75 of 79 cases (95%) in lymphoscintigraphy and 76 of 79 cases (96%) during surgery. SLN metastases was detected in 30 of 75 (40%) cases either in SLNB and ALND groups. Accuracy of SLNB method for detecting LN metastases was 92%. False negative rate was 3 of 30 of positive cases: 10%. In 7 of 10 cases with axillary lymphadenopathy, LN metastastates was detected. CONCLUSION SLNB is recommended for patients with various tumor sizes without palpable lymph nodes. In modified conventional pathologic examination of SLNs, at least macrometastases and some micrometastases could be detected similar to ALND. Consequently, ALND could be omitted in node-negative cases with removal of all palpable LNs. We conclude that SLNB, as one of the most important developments in breast cancer surgery, could be expanded even in areas without sophisticated pathology facilities.

Abstract
BACKGROUND Molecular diagnostic methods have played and continuing to have a critical role in clinical laboratories in recent years. Therefore, standardization is an evolutionary process that needs to be upgrade with increasing scientific knowledge, improvement of the instruments and techniques. The aim of this study was to design a quality assurance program in order to have similar conditions for all medical laboratories engaging with molecular tests. METHODS We had to design a plan for all four elements; required space conditions, equipments, training, and basic guidelines. Necessary guidelines was prepared and confirmed by the launched specific committee at the Health Reference Laboratory. RESULTS Several workshops were also held for medical laboratories directors and staffs, quality control manager of molecular companies, directors and nominees from universities. Accreditation of equipments and molecular material was followed parallel with rest of program. Now we are going to accredit medical laboratories and to evaluate the success of the program. CONCLUSION Accreditation of medical laboratory will be succeeding if its basic elements are provided in advance. Professional practice guidelines, holding training and performing accreditation the molecular materials and equipments ensured us that laboratories are aware of best practices, proper interpretation, limitations of techniques, and technical issues. Now, active external auditing can improve the applied laboratory conditions toward the defined standard level.
