Abstract
Background Treatment response in High-grade Glioma (HGG) patients changes based on their genetic and biological characteristics. MiRNAs, as important regulators of drug and radiation resistance, and the Apparent Diffusion Coefficients (ADC) value of tumor can be used as a prognostic predictor for glioma. Objective This study aimed to identify some of the pre-treatment individual patient features for predicting the treatment response in HGG patients. Material and Methods In this prospective study, 18 HGG patients, who were candidated for chemo-radiation treatment, participated after informed consent of the patients. The investigated features were the expression level of miR-222 and miR-205 in plasma, the ADC value of tumor, Body Mass Index (BMI), and age. Treatment response was assessed, and Least Absolute Shrinkage and Selection Operator (LASSO) regression was used to obtain a model to predict the treatment response. Mann-Whitney U test was also applied to select the variables with a significant relationship with patients' treatment response. Results The LASSO coefficients for miR-205, miR-222, tumor's mean ADC value, BMI, and age were 3.611, -1.683, 2.468, -0.184, and -0.024, respectively. Mann-Whitney U test results showed miR-205 and tumor's mean ADC significantly related to treatment response (P-value<0.05). Conclusion The miR-205 expression level of the patient in plasma and tumor's mean ADC value has the potential for prognostic predictors in HGG.

Abstract
Background Cancer development is aided by the role of long noncoding RNAs (lncRNAs) that act as competing endogenous RNAs (ceRNAs) absorbing microRNAs (miRNAs). We aimed to discover a novel regulatory axis in colorectal cancer (CRC) and potential biomarkers based on miR-616-3p. Materials and Methods The gene expression omnibus database was mined for differentially expressed lncRNAs (DELs) and mRNAs. LncRNAs and mRNAs were predicted using the RegRNA and TargetScan databases. A combination of the ciBioPortal and Ensemble databases was used to locate the mRNAs. Cytoscape 3.7.1-built CeRNA networks. A quantitative real-time polymerase chain reaction (qRT-PCR) was utilized to confirm the expression levels of these RNA molecules. Statistical analyses were implemented by GraphPad Prism 9. Results qRT-PCR showed (Linc01282, lnc-MYADM-1:1, and Zinc Finger Protein 347 [ZNF347]) were overexpressed whereas, (salt-inducible kinases 1 [SIK1], and miR-616-3p) were down regulated. Conclusion These results identify unique, unreported lncRNAs as CRC prognostic biomarkers, as well as prospective mRNAs as new treatment targets and predictive biomarkers for CRC. In addition, our study uncovered unexplored ceRNA networks that should be studied further in CRC.

Abstract
Background Breast cancer (BC) is the leading cause of cancer death in women. The current study is designed to evaluate the association of lipid profiles, FBS, and body mass index (BMI) with BC recurrence and metastasis. Materials and Methods This is a case-control study on estrogen receptor-positive BC patients in Isfahan Province, Central Iran, between 2008 and 2020. The control group was patients who had no evidence of recurrence or metastasis at least 1 year after the end of chemotherapy and hormone therapy. The case group was patients with evidence of metastasis or recurrence within 1 year after the end of chemotherapy and hormone therapy. Fasting blood sugar (FBS), total cholesterol (Chol), triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were measured before treatment, after chemotherapy, and after hormone therapy as well as BMI in the case and control groups. Results There were 108 patients in the case and 119 patients in the control group with a mean age of 50.72 ± 13.26 and 51.91 ± 11.79, respectively. There were no meaningful differences between the case and control groups regarding serum FBS, Chol, TG, HDL, LDL, and BMI. Conclusion We found no association between serum FBS, lipid profile, and BMI at initial diagnosis and BC recurrence or metastasis.

Abstract
The use of nanoparticles as a sonosensitizer in cancer sonodynamic therapy has been gaining attention because of their great advantages in drug delivery applications. By conjugating chemotherapy agents with nanoparticles, we can develop a drug delivery platform, control drug release and improve the outcome of treatments. The in-vitro study described here evaluates the combination of AuSiO2 nanoparticles and dacarbazine (DTIC@AuSiO2) as a sonosensitizer for sonodynamic therapy of melanoma. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and flow cytometry assays revealed that the viability of B16F10 melanoma cells was significantly inhibited by the increase in apoptosis induction in treatment with DTIC@AuSiO2 nanoparticles under ultrasound exposure compared with treatment with the free DTIC or AuSiO2 nanoparticles. The sonosensitization activity of AuSiO2 nanoparticles and greater uptake of DTIC by tumor cells after loading in DTIC@AuSiO2 nanoparticles inhibited the proliferation of melanoma tumor cells effectively. In conclusion, the DTIC@AuSiO2 nanoparticles established in this study could represent a good drug delivery and sonosensitizer platform for use in melanoma sonodynamic therapy.

Abstract
Background: Long noncoding RNAs (lncRNAs) have been recognized as the main modulatory molecules in various cancers and perform as competing endogenous RNAs (ceRNAs). The nuclear hormone receptor superfamily of ligand-activated transcription factors (NR3C1) regulates numerous proliferative and metabolic processes such as tumorigenesis and metabolic diseases. Furthermore, X-linked inhibitor of apoptosis protein (XIAP) belongs to a family of the inhibitors of apoptosis proteins, is located downstream of the glucocorticoid receptor (GR or NR3C1) pathway, and cooperates with GR to suppress apoptosis. However, the underlying mechanisms of NR3C1 and XIAP in colorectal cancer (CRC) remain mainly unclear. This research aims to clarify the potential RNA biomarkers and to construct a novel ceRNA network in CRC. Materials and Methods: Multistep bioinformatics methods such as Lnc2cancer and miRDB databases were applied to identify candidate lncRNAs and miRNAs. The interaction energy between lncRNAs, NR3C1, and XIAP genes was analyzed by the LncRRIsearch database. Plus, microRNAs and lncRNA were evaluated via the Diana tools database to select microRNAs with the most binding scores. Quantitative reverse transcription–polymerase chain reaction (QRT-PCR) was applied to verify RNA molecules’ expression levels and their association with the clinicopathological factors in 30 CRC tissues compared to 30 adjacent tissues. Results: QRT-PCR showed upregulation of KCNQ1OT1, NR3C1, and XIAP and downregulation of miR-421. The ceRNA network was constructed with 17 lncRNAs, 2 mRNAs, and 42 miRNAs. Thus, we explained the potential interactions between KCNQ1OT1 and miR-421 with NR3C1 and XIAP genes. Conclusion: Our study represents potential prognostic biomarkers and a new ceRNA network for further study in CRC.

Abstract
It is clear that biofilm formation causes many serious health-care problems. Interestingly, sub minimum inhibitory concentrations (sub-MICs) of some biocides can induce biofilm formation in bacteria. We investigated whether sub-MICs of Savlon, chlorhexidine and deconex®, as biocidal products, can induce biofilm formation in clinical isolates of Pseudomonas aeruginosa. To determine MICs and biofilm formation, we performed microtitre plate assays. All three biocides induced biofilm formation at sub-MICs; Savlon was the most successful antiseptic agent to induce biofilm formation among P. aeruginosa isolates. Deconex had the best inhibition effect on planktonic cultures of P. aeruginosa isolates. We concluded that sub-MICs of Savlon and deconex could significantly induce biofilm formation.

Abstract
BACKGROUND Oral squamous cell carcinoma (SCC) is the most common oral malignancy. Some evidence indicated that there is a correlation between microRNA single nucleotide polymorphisms and the risk of oral cancer. The aim of the current study was to investigate the association between mir-499 polymorphism with the risk of oral cavity and oropharyngeal SCC in a subset of Iranian Population. MATERIALS AND METHODS In this case-control pilot study total of 112 participants including 56 histopathlogically confirmed oral and oropharyngeal SCC patients and 56 age- and sex-matched controls were included The mir-499 rs3746444 T/C polymorphism was detected using polymerase chain reaction-restriction fragment length polymorphism method. The comparisons of the distribution of the allele and genotype frequencies were performed using Chi-square test, and P < 0.05 was considered as statistically significant. RESULTS The result of the present study indicated that the frequency distribution of mir-499 was not significantly different between cases and controls (P > 0.05). We also did not find any significant association between the risk of the cancer and mir-499 polymorphisms in the recessive (Odds ratio [OR]: 6.60; 95% confidence interval [CI]: 0.77-56.74; P = 0.11) and dominant (OR: 1; 95% CI: 0.37-2.74; P = 1) inheritance models even after adjustment for smoking. CONCLUSION The results of the present study indicated that the polymorphisms of mir-499 are not associated with the risk of oral and oropharyngeal SCC in Iranian population. However, further large scale studies are needed to validate our findings.

Abstract
Introduction Healthcare professionals should seek the necessary resources to improve the quality of care. Given the cultural, social, and economic differences, in every health care system, there are increasing needs for the adapted versions of clinical practice guidelines (CPGs). This study aimed to introduce an innovative CPG adaptation approach for nurses working in a developing country. Methods This study is comprised of three sections: a. An extensive systematic search of the literature, b. The adaptation process, c. Interviews, which were held with stakeholders, users and/or the target population. We applied all of the stages of guideline adaptation process according to Adaptation Resource Toolkit, with the integration of the findings of a systematic literature search and a qualitative content analysis in an “adolopted” new CPG. Results In this study, we applied a mix of three methods namely adoption, adaptation and development (adolopment) of recommendations to save time, cost, and manpower efficiently. Moreover, we integrated the utilized qualitative research method and literature review with the adolopment approach to develop the recommendations. Conclusion Given there is a paucity of nursing clinical practice guidelines (NCPGs) in the nursing management of cancer therapy-induced mucositis and to save time and costs, the findings emerging from the adoption, adaptation, and de novo guideline development by a panel of experts and qualitative content analysis (QCA) method were integrated to achieve a more comprehensive nursing practice guideline. ![]()

Abstract
83 Background: Breast carcinoma is the second cause of mortality between female cancers and metastasis is the main contributing factor to the mortality in patients with breast cancer. Optimal management for visceral metastatic breast cancer (MBC) remains unknown. In this study we aimed to assess if adding pioglitazone to chemotherapy regimen can improve response in patients with MBC. Methods: This double-blind randomized clinical trial enrolled women 18 years or older with visceral MBC either previously treated with adjuvant therapy or currently are undergoing different lines of endocrine and chemotherapy regimens. The main objective of this study is to compare treatment efficacy in patients with visceral MBC taking chemotherapy plus Pioglitazone (n = 30) versus chemotherapy in addition to placebo (n = 30) over three months. The efficacy evaluated by change in radiologic response defined by the proportion of patients with stable or partial/complete radiologic response to those experienced disease progression based on Revised Recist Guideline ver (1.1). Results: Combination of pioglitazone and chemotherapy led to higher complete radiologic response (7.4% vs.0%) stable disease status (66·7% vs. 53·6%) and lower progression (22·2% vs. 35·7%) rates, however the differences were not statistically significant (P = 0.24). Clinical benefit rate (CBR, proportion of patients with complete response, partial response, or stable disease) was 77.8% in pioglitazone group vs. 64.3% in control group (p = 0.27). Subgroup analysis revealed higher efficacy but not statistically significant among diabetic woman, who had hormone-receptor–positive tumor. Furthermore, patients treated with Taxan +/-Carboplatin agents had significantly higher stable disease status, lower progression rate and higher complete response rate than the placebo group (P = 0·03). Conclusions: This is the first reported randomized clinical trial on the efficacy of pioglitazone in patients with visceral MBC which demonstrated safety and improvement of response in the subgroup of Taxan / Carboplatin chemotherapy regimen. These findings are in agreement with previous results of in vitro preclinical studies. Clinical trial information: IRCT20180124038493N1.

Abstract
Gastric cancer is one of the most common upper gastrointestinal malignancies. Some Iranian provinces, such as in the northern and northwestern areas, are at a high risk, whereas the central and western provinces are at a medium and the southern regions at low risk. This study was carried out to estimate the impact of the expression patterns of ASIC1 and IL-6 genes and the IL-6rs-174 and ASIC1rs 75624685 polymorphisms in the pathogenesis of gastric cancer. Materials and methods: Tetra-ARMS PCR was employed to analyze the polymorphism status of the ASIC1 and IL-6 genes with 85 paraffin-embedded tissue blocks from cases and 117 normal blood samples as controls. We also investigated mRNA expression levels of these genes in 12 cases and controls using real-time PCR. Results: Our results showed a significant association between expression of ASIC1 and elevated risk of gastric cancer (p<0.001).

Abstract
Background: Febrile neutropenia is a common and serious chemotherapy side effect, is associated with increased mortality, morbidity, and treatment expenditures. Several CPGs (Clinical practice guidelines) have been released for managing chemotherapy-induced febrile neutropenia. The aim of this study is Appraisal of the clinical practice Guidelines quality in the management of chemotherapy-induced febrile neutropenia. Methods: A review study with a systematic search of the present CPGs for the management of chemotherapy-induced febrile neutropenia. After screening the CPGs based on eligibility criteria, three CPGs were selected and 5 independent reviewers appraised them for methodological quality by using the AGREE II Instrument. Results: Three CPGs were included; all of them were evidence-based guidelines. The clarity of presentation domain scored the highest and the applicability domain has the lowest score among all domains of AGREE instrument and the rest of domains scored as descending respectively; Scope and purpose, stakeholder involvement, editorial independence, rigor of development. In general, the intra-class correlation coefficient (ICC) scores of all domains were very good according to the Landis and Koch’s scale, except the Applicability domain scored as substantial. Conclusions: This study showed the quality of appraised CPGs. Three domains of these CPGs based on the AGREE instrument scored less than other domains and were in relatively unfavorable status: applicability, rigor of development, editorial independence. Given the importance of these domains in guideline implementation, it is necessary to take actions for reducing these defects.

Abstract
Chemotherapy-induced peripheral neuropathy is a common adverse effect occurring in patients undergoing neurotoxic chemotherapy. However, there is no FDA-approved treatment option for it. Given the importance of clinical practice guidelines in this area, this study aimed to determine the methodological quality of extant CIPN guidelines. The study was done as part of the adaptation process of CIPN related CPGs at Isfahan University of Medical Sciences, Iran. A systematic search of published CPGs about chemotherapy-induced CIPN in which the AGREE II instrument was applied for appraising CPGs of CIPN was performed. In general, amongst all of the AGREE II Instrument’s domains in the evaluated CPGs, the clarity of presentation and stakeholder involvement domains took favorable scores; and other domains obtained unfavorable and relatively favorable scores. The quality of cancer therapy-induced neuropathy CPGs needs to be improved and designing high-quality CPGs must be considered.

Abstract
Leishmaniasis is rising in many countries, including Iran, due to climate change, refugee crises, urbanization and etc. The aim of this study was to explore the epidemiology, extent and identity of Leishmania species in a newly emerged focus in Abdanan County, Ilam Province, South-western Iran. This study was performed as a descriptive cross-sectional study by a systematic house-to-house approach. The Leishmania species was identified by RFLP-PCR and sequencing. Altogether, 46799 individuals consisting of 22907 (48.9) female and 23892 (51.1%) male were interviewed and physically examined for the presence of skin lesions. Overall, the incidence rate was 0.34% (n = 160). All age groups were affected and the incidence rate was the highest in <10 years of age group (0.49%) and the lowest in >50 years old individuals (0.15%), although there was no significant difference regarding the sex and age. The majority of patients had one lesion (47.5%) on hands (56%) and most of the cases occurred in Abdanan city (%54) in summer. Based on the RFLP-PCR analysis, all the Leishmania isolates were L. major of single genotype. A newly emerged focus of zoonotic CL caused by L. major occurred in South-western of Iran. Multiple risk factors created this epidemic area. Further studies on the vector and reservoir are crucial needed to provide evidences to select the prophylactic and therapeutic measures for future control strategies.

Abstract
Background Adenosine receptors (A1, A2A, A2B, A3) play an important role in the regulation of growth, proliferation and death of cancer and normal cells. We recently showed the expression profile of A2A and A2B receptors in normal and tumor breast tissues. In the present study, we used semiquantitative RT-PCR to measure the A1 and A3 gene expression levels in normal and tumor breast tissues. Methods Breast tumors (n = 18) and non-neoplastic mammary tissues (n = 10) were collected and histologically confirmed to be neoplastic or non-neoplastic, respectively. Total RNA was extracted and reverse transcribed into cDNA, and PCR was performed under optimized condition for each receptor subtype. Amplification of beta-actin mRNA served as control for RT-PCR. The PCR products were separated on 1.7% agarose gels. The intensity of the bands was quantitated with ImageJ software after normalization against beta-actin expression. Results All breast tumor and normal tissue specimens expressed A1 and A3 adenosine receptor transcripts. However, we observed that the expression level of the A3 receptor in tumor tissues was 1.27-fold that of normal tissues, whereas there was no significant difference between the expression levels of A1 in normal and tumor tissues. Conclusions Interestingly, the results of the present study indicate that breast tumors exhibit a higher level of A3 transcripts (than normal tissues) and support the possible key role of A3 adenosine receptor in tumor development. However, further studies based on real-time quantitative RT-PCR are needed to identify the exact gene expression levels.

Abstract
Introduction: Hepatitis B virus (HBV) infection and its complications are major public health problems. As it is hard to treat and control the chronic state, control of disease depends on the prevention especially by vaccination. There is an impaired immune response to vaccinations including HBV in patients with some malignancies. The aim of this study is to assess the response rate of patients undergoing chemotherapy to HBV vaccination. Materials and Methods: All patients from two hematology/oncology clinics in Isfahan, Iran with the history of at least 1 month chemotherapy who had the inclusion criteria were enrolled in a case control study. Also a sex- and age-matched control group from healthy population was selected. They were vaccinated in a schedule of 0, 1, and 6 months and were examined for antibody titers 1 month after the last dose. The titers more than 10 mIU/ml were determined as positive response to vaccination. Results: In this study, 50 patients and 50 healthy subjects were enrolled. The two groups were age and sex matched (P > 0.05). Frequency of negative responses to HBV vaccination in case and control groups were 9 (18%) and 1 (2%), respectively (OR = 10.75, CI = 1.30–88.47, P = 0.027). Of 50 patients, 54%, 12%, 22%, and 12% had breast cancer, lymphoma, gastrointestinal, and genitourinary cancers, respectively, and frequency of negative responses were 3 (11%), 1 (16%), 4 (36.4%), and 1 (16%), respectively (P = 0.167). Conclusion: According to our results, malignancy and chemotherapy will have an important effect on the immune system and cause negative response to HBV vaccination. Our results revealed the importance of passive immunity and screening for HBV infection in patients undergoing chemotherapy. Also more studies for better vaccination schedules in this group of patients are recommended.

Abstract
BACKGROUND Li-Fraumeni syndrome (LFS) is one of the most serious hereditary cancer syndromes with a high risk of malignancy in childhood. This syndrome is an autosomal dominant cancer predisposing syndrome due to a germline mutation in the TP53 tumor suppressor gene. METHODS In this study, a representative family case of Li-Fraumeni syndrome is described. The proband of this family was a 43-year-old male who had osteosarcoma of the mandible and a positive family history of cancer. His mother died at the age of 29 of brain cancer; his sister died at the age of 18 of breast cancer; his brother died at the age of 36 of liver cancer; and another sister of his died at the age of 16 of leukemia. Complete sequence analysis of the TP53 and PTEN genes was performed in this family. We used standard diagnostic tools such as sequencing and multiplex ligation-dependent probe amplification (MLPA) to analyze these two genes in this family. The exons and flanking exon-intron junctions of the TP53 and PTEN genes were sequenced. RESULTS We detected a germline mutation in the TP53 gene in this family that was previously reported as somatic mutation in LFS in the catalogue of somatic mutations in cancer (COSMIC). In addition, according to the International Agency for Research of Cancer (IARC) database, a 19-year-old male patient with sarcoma was recently reported to have this germline mutation. We also found two new IVS variations in the PTEN gene, one of which can be a suggestive evidence of an effect on the splicing of PTEN. CONCLUSION Genomic modifications for tumor risk and genotype-phenotype correlations in LFS are still to be identified. We believe every new finding in this area can provide new insights into the pathogenesis and progression of Li-Fraumeni syndrome.

Abstract
BACKGROUND Aprepitant is one of the effective antiemetic drugs that usually used for a period of 3 days for prevention of anthracycline/cyclophosphamide (AC) induced nausea and vomiting. However, many patients still experience nausea and vomiting on days 3-5. The aim of this study was to evaluate the effect of an increase in duration of aprepitant consumption from 3 to 6 days on the prevention of nausea and vomiting in women receiving AC chemotherapy. MATERIALS AND METHODS It was a randomized, crossover, controlled clinical trial. Women with breast cancer and scheduled to receive AC regimens were enrolled in this study. Enrolled patients were randomized into two groups. Group I received 3 days regimen of aprepitant in the first course of AC regimen chemotherapy and 6 days regimen of aprepitant in the second course; Group II received 6 days regimen followed by 3 days regimen. For nausea and vomiting assessment, we used Eastern Cooperative Oncology Group questionnaire. RESULTS Forty-nine patients were enrolled in this study. Sixty-three percent achieved a complete response with 6 days aprepitant regimen compared with 39% with 3 days regimen (P < 0.001). Ten percent had at least one vomiting episode during the 6 days regimen versus 15% with 3 days regimen (P = 0.034). Nausea was significantly more severe in 3 days regimen of aprepitant than in 6 days regimen. CONCLUSION Increase in the duration of aprepitant consumption through 6 days resulted in significantly better prevention of nausea and vomiting than 3 days consumption for women receiving AC chemotherapy.

Abstract
Raw milk contains diverse nutritional components that provide a suitable medium for spoilage and the growth of potentially pathogenic microorganisms. Unpasteurized milk consumption by a large number of people can threaten health and increase public concerns. In this study, sixty-two raw cows milk samples were collected from the dairy farms of Ilam, Western Iran. All samples were collected in sterilized containers and were transferred via ice boxes to the laboratory. Isolates were then identified by standard methods. Totally, 88.7% (n=55) of samples were contaminated. Our study also showed that Escherichia coli had a high prevalence among isolates (43: 69.4%), while Klebsiella pneumoniae and Klebsiella planticola showed the lowest prevalence (1: 1.6%). Staphylococcus aureus was also detected in 17.7% (n=11) of samples. The raw milk microbial contamination is complex. Some of the microorganisms threaten public health via different traits, therefore it is recommended that raw milk consumption should be avoided.

Abstract
CONTEXT Various symptoms frequently affect cancer patients' quality of life. Appropriate assessment of these symptoms provides valuable data for cancer management. OBJECTIVES This study aimed to validate the Persian version of the M. D. Anderson Symptom Inventory (MDASI-P). METHODS This cross-sectional study was conducted at four cancer treatment centers in two cities in Iran. Breast cancer and colorectal cancer patients aged 18 years and older were consecutively included in the study. The standard forward-backward translation method was applied. Patients completed the MDASI-P along with the previously validated Persian version of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30). Construct validity (factor analysis), criterion validity (against the EORTC QLQ-C30), and reliability (Cronbach's alpha) were analyzed. RESULTS A total of 146 breast cancer and 94 colorectal cancer patients were studied. Factor analysis for the symptom severity items resulted in a three-factor solution, further reduced to a two-factor solution: general symptoms and gastrointestinal symptoms. Correlation of the MDASI-P symptom severity items with corresponding EORTC QLQ-C30 symptom items (r = 0.48-0.75) and MDASI-P interference items with corresponding EORTC QLQ-C30 functioning domains (r = -0.46 to -0.23) supported the criterion validity. Cronbach's alpha was 0.90, 0.88, and 0.77 for the total questionnaire, symptom severity items, and the interference subscale, respectively. CONCLUSION The MDASI-P is a feasible, valid, and reliable instrument for evaluation of symptoms in Persian-speaking cancer patients and can be used to improve symptom management in these patients.

Abstract
BACKGROUND AND AIM Cytotoxic T lymphocyte-associated antigen-4 (CTLA4) is a crucial immune-checkpoint receptor regulating T-cell activation. The current study was carried out to evaluate the function of CTLA4 gene in patients with gastric cancer. METHODS The methylation of CTLA4 gene promoter was evaluated by methylation-specific polymerase chain reaction (MSP) technique using 85 paraffin-embedded gastric cancer tissue samples and normal tissue on the tumor margins as control tissue samples. Expression analysis was performed on paraffin-embedded tissue samples (25 each of cancerous and normal tissues) using Real-time PCR. RESULTS Statistically significant differences were observed between the tumor and margin-cell areas with respect to promoter methylation status (OR = 4.829, 95% CI: 2.46-9.48, p < 0.001) and CTLA4 expression profile (mean +/- SD = 7.56 +/- 17.35, p = 0.04). CONCLUSION To the best of our knowledge, the current study is the first one highlighting the association between promoter hypermethylation of CTLA4 gene, decreased CTLA4 expression, and increased risk of gastric cancer.

Abstract
PURPOSE Radiation-induced injury to normal tissues is a common complication of radiation therapy in cancer patients. Considering the role of vitamin D in mucosal barrier hemostasis and inflammatory responses, we investigated whether vitamin D deficiency is associated with the severity of radiation-induced acute proctitis in cancer patients. METHODS AND MATERIALS This prospective observational study was conducted in cancer patients referred for pelvic radiation therapy. Serum concentration of 25-hydroxyvitamin D was measured before radiation therapy. Vitamin D deficiency was defined as 25-hydroxyvitamin D concentrations of <35 nmol/L and <40 nmol/L in male and female patients, respectively, based on available normative data. Acute proctitis was assessed after 5 weeks of radiation therapy (total received radiation dose of 50 Gy) and graded from 0 to 4 using Radiation Therapy Oncology Group (RTOG) criteria. RESULTS Ninety-eight patients (57.1% male) with a mean age of 62.8 ± 9.1 years were studied. Vitamin D deficiency was found in 57 patients (58.1%). Symptoms of acute proctitis occurred in 72 patients (73.4%) after radiation therapy. RTOG grade was significantly higher in patients with vitamin D deficiency than in normal cases (median [interquartile range] of 2 [0.5-3] vs 1 [0-2], P=.037). Vitamin D deficiency was associated with RTOG grade of ≥2, independent of possible confounding factors; odds ratio (95% confidence interval) = 3.07 (1.27-7.50), P=.013. CONCLUSIONS Vitamin D deficiency is associated with increased severity of radiation-induced acute proctitis. Investigating the underlying mechanisms of this association and evaluating the effectiveness of vitamin D therapy in preventing radiation-induced acute proctitis is warranted.

Abstract
BACKGROUND AND AIM There is evidence that gastric cancer patients suffer from thyroid disorders. However, the relationship between thyroid receptor (TR) expression and gastric cancer remains unknown. The aim of this study was to evaluate the status of promoter methylation and expression of the thyroid hormone receptor beta (THRβ) gene in gastric cancer patients in an Iranian population. METHODS Analysis of THRβ promoter methylation was performed on 85 pairs of formalin-fixed, paraffin-embedded (FFPE) tissue samples as cases and controls via methylation-specific polymerase chain reaction (PCR [MSP]). The samples were obtained from tumors and surrounding healthy tissues from resected gastric cancers. The expression assay was also performed with 25 FFPE tissue pairs (tumor and surrounding healthy tissues of the same individual) using real-time PCR. RESULTS The results of the present study show that there is a statistically significant difference between tumor and adjacent normal tissues regarding promoter methylation status and THRβ expression (P = 0.04 and P = 0.036, respectively). CONCLUSION Therefore, promoter methylation of THRβ may be involved in the development of gastric cancer.

Abstract
Background: Oral mucositis is a debilitating side effect of cancer treatment for which there is not much successful treatments at yet. We evaluated the effectiveness of topical morphine compared with a routine mouthwash in managing cancer treatment-induced mucositis. Materials and Methods: Thirty head and neck cancer patients with severe mucositis (World Health Organization Grade III or IV) were randomized into the morphine and magic mouthwash groups. Patients received morphine sulfate 2% or magic solution (contained magnesium aluminum hydroxide, viscous lidocaine, and diphenhydramine), 10 ml for every 3 h, six times a day, for 6 days. Both groups received same dietary and oral hygiene instructions and care. Mucositis was graded at baseline and every 3 days after treatment. Patients’ satisfaction and drug effect maintenance were also evaluated. Results: Twenty-eight patients (mean age of 49.5 ± 13.2 years, 63.3% female) completed the trial; 15 in the morphine group and 13 in the magic group. There was a decrease in mucositis severity in both of the morphine (P < 0.001) and magic (P = 0.049) groups. However, at the 6th day, more reduction was observed in mucositis severity in the morphine compared with magic group (P = 0.045). Drug effect maintenance was similar between the two groups, but patients in the morphine group were more satisfied by their treatments than those in the magic group (P = 0.008). Conclusions: Topical morphine is more effective and more satisfactory to patients than the magic mouthwash in reducing severity of cancer treatment-induced oral mucositis. More studies with larger sample size and longer follow-up are required in this regard.

Abstract
OBJECTIVES There is still contradictory evidence on disclosure preferences regarding cancer diagnosis. The aim of this study was to evaluate the preference of cancer patients for knowing the truth about their disease, as well as the factors that might have an impact on these preferences. METHOD This study was conducted in 11 cancer centers in Iran. A questionnaire was used to collect data, and all patients above 15 years of age who were willing to participate were included in the study. The patients were asked if they were aware of the malignant nature of their disease, and if they came to know about their disease at the time of initial diagnosis, or later. The patients were then asked about the way they looked upon their disease. In the final part of the questionnaire, the participants were asked the level of involvement they prefer to have in making treatment decisions. RESULTS In total, 1226 patients were enrolled in this study, only 565 (46.7%) of whom were aware of their disease at the time of diagnosis, and 878 (72.7%) at the time of interview, while 980 (85.2%) were willing to receive information about their disease. Patients' awareness was significantly associated with age under 50 years, female gender, having breast, skin or head and neck cancer, and having medical care in Shiraz or Hamadan while it was not associated with the stage or accompanying illness. CONCLUSION While the majority of Iranian cancer patients prefer to be aware of the nature of their disease and have an active role in treatment decision making, they do not receive this information.

Abstract
BACKGROUND Taste abnormalities are common among cancer patients after starting radiotherapy or chemotherapy. Considering the role of zinc and reports on its beneficial effects in taste perception, we evaluated the preventive effects of zinc sulfate on radiation-induced taste alterations. MATERIALS AND METHODS In a randomized, placebo-controlled trial, adult patients with head and neck cancers who were on schedule for radiotherapy, with or without chemotherapy, were allocated to receive zinc sulfate (50 mg, three times a day) or placebo; started with beginning of radiotherapy and continued for one month later. Taste acuity was determined by measuring detection and recognition thresholds for four taste qualities at baseline, at the end of radiotherapy, and a month later using the Henkin method. RESULTS Thirty-five patients (mean age = 59.2 ± 16.5, 60% male) completed the trial. The two groups were similar at baseline. After radiotherapy, and one month later, there was a significant increase in taste perception threshold for bitter, salty, sweet, and sour tastes in the placebo group (P = 0.001). In those who received zinc, there was only slight increase in threshold for perception of the salty taste (P = 0.046). No relevant side effects due to zinc sulfate were reported. CONCLUSION Zinc supplementation in head/neck cancer patients under radiotherapy can prevent radiation-induced taste alterations. Further studies with longer follow-ups and with different doses of zinc supplementation are warranted in this regard.

Abstract
BACKGROUND Adenosine receptors (A1, A2A, A2B, A3) play an important role in the regulation of growth, proliferation and death of cancer and normal cells. We recently showed the expression profile of A2A and A2B receptors in normal and tumor breast tissues. In the present study, we used semiquantitative RT-PCR to measure the A1 and A3 gene expression levels in normal and tumor breast tissues. METHODS Breast tumors (n = 18) and non-neoplastic mammary tissues (n = 10) were collected and histologically confirmed to be neoplastic or non-neoplastic, respectively. Total RNA was extracted and reverse transcribed into cDNA, and PCR was performed under optimized condition for each receptor subtype. Amplification of beta-actin mRNA served as control for RT-PCR. The PCR products were separated on 1.7% agarose gels. The intensity of the bands was quantitated with ImageJ software after normalization against beta-actin expression. RESULTS All breast tumor and normal tissue specimens expressed A1 and A3 adenosine receptor transcripts. However, we observed that the expression level of the A3 receptor in tumor tissues was 1.27-fold that of normal tissues, whereas there was no significant difference between the expression levels of A1 in normal and tumor tissues. CONCLUSIONS Interestingly, the results of the present study indicate that breast tumors exhibit a higher level of A3 transcripts (than normal tissues) and support the possible key role of A3 adenosine receptor in tumor development. However, further studies based on real-time quantitative RT-PCR are needed to identify the exact gene expression levels.

Abstract
The significance of translation regulatory factors in elevating the risk of cancer has been recently recognized. Eukaryotic release factor 3a (eRF3a) is a translation termination protein that is encoded by G1 to S phase transition 1 gene (GSPT1). The eRF3a/GSPT1 exon 1 contains a trinucleotide GGC repeat coding for a polyglycine expansion in the N-terminal of the protein. In the present study, we determined the allelic length of the GGC(n) repeat in the eRF3a gene in 250 women with breast cancer and 250 age-matched controls. Our results show that the presence of the longer allele, 12-GGC, is correlated with threefold increased risk of breast cancer development. Our findings also suggest that women who are homozygous for 7-GGC allele are possibly at higher risk of developing breast cancer, especially before the age of 50. No significant effect of the allelic length of eRF3a/GSPT1 polymorphism on inheritance or the grade of this disease was observed.

Abstract
OBJECTIVE Low quality of the bone and insufficient bone due to the size of the sinus and resorption of the alveolar ridge decrease the long-term survival of implants in the posterior maxilla compared to other regions of the jaws. Surgical procedures to increase bone volume make it possible to place implants longer than 8 mm. In this situation sinus elevation makes it possible to place implants. We intend to evaluate peri-implant bone loss and survival of implants placed in elevated sinuses after 2 years and to compare with implants placed in the native posterior maxilla. MATERIALS AND METHODS Twenty-five implants placed in sinuses that had been reconstructed with Bio-Oss and healed after 9 months were compared with 30 implants placed in the posterior maxilla without any surgery. The groups were compared using probing pocket depth, bleeding on probing, Plaque Index and bone loss immediately after implant placement surgery and 2 years postoperatively. The criterion for implant survival was presence or absence of the implant in the oral cavity, which was recorded in relevant forms in both groups. RESULTS Three implants were lost; one in control and two in grafted sinuses. No significant differences were observed in the survival rates. In general, the mean bone loss around intrasinus and extrasinus implants was not significantly different. In the same context, no differences were observed between bleeding on probing, Plaque Index and probing pocket depths of two groups (P=0.397, P=0.637 and P=0.224, respectively). CONCLUSION The survival and bone loss around intrasinus and extrasinus implants are similar.

Abstract
We studied the association of breast cancer with the polymorphic CA repeat in 108 cases of breast cancer and 108 matched controls from Isfahan city of Iran. The most common genotype in controls and patients was homozygous with allele length of 16. Our findings demonstrate that Women with two short CA repeat (< 19) are at a significantly higher risk of breast cancer, at an estimated odds ratio of 1.86. We have also found that women with short alleles (< 19) had much greater risk of developing cancer before the age of 55 (OR, 3.36).
