Context Breast cancer is the most common cancer in women worldwide. Estrogen receptor (ER) positive breast cancer constitutes the majority of these cancers. Hormone therapy has significantly improved clinical outcomes for early- and late-stage hormone receptor positive breast cancer. Although most patients with early stage breast cancer are treated with curative intent, approximately 20% - 30% of patients eventually experience a recurrence. During the last two decades, there have been tremendous efforts to understand the biological mechanisms of hormone therapy resistance, with the ultimate goal of implementing new therapeutic strategies to improve the current treatments for ER positive breast cancer. Several mechanisms of hormone therapy resistance have been proposed, including genetic alterations that lead to altered ER expression or ERs with changed protein sequence. Evidence Acquisition A Pubmed search was performed utilizing various related terms. Articles over the past 20 years were analyzed and selected for review. Results On the basis of published studies, the frequencies of ESR1 (the gene encoding ER) mutations in ER positive metastatic breast cancer range from 11% to 55%. Future larger prospective studies with standardized mutation detection methods may be necessary to determine the true incidence of ESR1 mutations. ESR1 amplification in breast cancer remains a controversial issue, with numerous studies either confirmed or challenged the reports of ESR1 amplification. The combination of intra-tumor heterogeneity regarding ESR1 copy number alterations and low level ESR1 copy number increase may account for these discrepancies. Conclusions While numerous unknown issues on the role of ESR1 mutations in advanced breast cancer remain, these new findings will certainly deepen current knowledge on molecular evolution of breast cancer and acquired resistance to hormone therapy.

乳腺癌是全世界女性中最常见的癌症。雌激素受体(ER)阳性乳腺癌构成了这些癌症的大多数。激素治疗显著改善了早期和晚期激素受体阳性乳腺癌的临床结果。虽然大多数早期乳腺癌患者的治疗目的是治愈，但大约20% - 30%的患者最终会复发。在过去的二十年里，人们已经付出了巨大的努力来了解激素治疗抵抗的生物学机制，最终目标是实施新的治疗策略来改善目前对雌激素受体阳性乳腺癌的治疗。已经提出了激素治疗耐药的几种机制，包括导致内质网表达改变或内质网蛋白序列改变的遗传改变。利用各种相关术语进行Pubmed检索。对过去20年的文章进行了分析和选择。结果根据已发表的研究，在ER阳性转移性乳腺癌中，ESR1(编码ER的基因)突变的频率为11% ~ 55%。未来可能需要使用标准化突变检测方法进行更大规模的前瞻性研究，以确定ESR1突变的真实发生率。乳腺癌中的ESR1扩增仍然是一个有争议的问题，许多研究证实或质疑ESR1扩增的报道。肿瘤内ESR1拷贝数改变的异质性和低水平的ESR1拷贝数增加可能解释了这些差异。尽管ESR1突变在晚期乳腺癌中的作用仍有许多未知问题，但这些新发现必将加深目前对乳腺癌分子进化和获得性激素治疗耐药的认识。

Background Cancer diagnosis for everybody may be perceived as crisis and breast cancer, as the most common malignancy in women, can influence their well-being and multiple aspects of their health. So understanding that how women in various contexts and communities adjust to the illness is necessary to facilitate this adjustment and improve their quality of life. Objectives The aim of this study was to: 1) identify the core components of coping strategies to adjust to the illness in Iranian women with breast cancer perspective, 2) to develop and determine psychometric properties of a native self-report instrument to assess coping behaviors and measure the degree of adjustment with the breast cancer. Methods The present exploratory mixed method study was conducted in two consecutive stages: 1) the hermeneutic phenomenological study was done to explore the life experiences of coping styles to adjust with the breast cancer using in-depth interviews with patients that lead to item generation; 2) psychometric properties (validity and reliability) of the instrument were evaluated recruiting 340 eligible women. The item pool was reduced systematically and resulted in a 49-item instrument. Results From the qualitative stage, item pool containing 78 items related to coping strategies to adjust with the breast cancer. After eliminating unwanted statements from the results, qualitative and quantitative face and content validity, the 10 factors extracted employing construct validity were: feeling of guilt, abstention-diversion, role preservation and seeking support, efforts for threat control, confronting, fear and anxiety, role wasting, maturation and growth, isolation, and fatalism. These factors accounted for the 59.1% of variance observed. The Cronbach reliability test was carried out and alpha value of 10 factors was calculated from 0.78 to 0.87 confirming all factors were internally consistent. The scale’s stability was tested using the test-retest method. Conclusions The 49-item AIMI-IBC revealed acceptable psychometric properties. This instrument provides healthcare professionals to systematically assess the coping strategies of Iranian women with breast cancer and measure the degree of adjustment with illness.

Background Aberrant expression of cancer-testis antigens (CTA) in breast carcinoma tissue, and its natural expression in the testis, the tissue away from the immune system, makes them good candidates for cancer immunotherapy and vaccines designing. Objectives The aim of this study was to assess the expression of a CTA (MAGE-1) in invasive breast cancer and its correlation with prognostic factors. Methods Paraffin blocks of breast cancer tissues from 113 patients operated in 2011 - 2013 were stained for MAGE-1expression by immunohistochemistry (IHC). The associations of MAGE-1 expression with known prognostic factors were assessed by statistical analysis using SPSS 16. Results MAGE-1 expression was found in cancer cell cytoplasms of 30.1% of patients, with different degrees of intensity, (23.9% moderate and 6.2% strong). Nuclear staining turned positive in 31.8%, stratified from moderate in 26.5%to to strong in 5.3%. There was a significant association between the number of lymph nodes involved and both nuclear (P = 0.042) and cytoplasmic (P = 0.003) MAGE-1 expression. There was also a significant correlation between the nuclear expression of MAGE-1 and tumor size (P = 0.018). Cytoplasmic expression of MAGE-1 increased with increasing pathologic grade of tumors although the association was not statistically significant (P = 0.119). Conclusions CTA MAGE-1 has significant association with some prognostic factors in breast cancer and may have the role of a prognostic factor.

肿瘤睾丸抗原(CTA)在乳腺癌组织中的异常表达及其在远离免疫系统的睾丸组织中的自然表达，使其成为癌症免疫治疗和疫苗设计的良好候选者。目的本研究的目的是评估CTA (MAGE-1)在浸润性乳腺癌中的表达及其与预后因素的相关性。方法采用免疫组化(IHC)方法对2011 - 2013年113例乳腺癌患者的组织石蜡块进行mage -1表达染色。使用SPSS 16进行统计分析，评估MAGE-1表达与已知预后因素的相关性。结果30.1%的患者癌细胞细胞质中存在不同程度的MAGE-1表达，其中中度表达23.9%，强烈表达6.2%。核染色变为阳性的占31.8%，从中度(26.5%)到强烈(5.3%)分层。淋巴结受累数与细胞核(P = 0.042)和细胞质(P = 0.003) MAGE-1表达均有显著相关性。MAGE-1的核表达与肿瘤大小也有显著相关性(P = 0.018)。MAGE-1的细胞质表达随肿瘤病理分级的增加而增加，但相关性无统计学意义(P = 0.119)。结论CTA MAGE-1与乳腺癌的一些预后因素有显著相关性，可能具有预后因素的作用。

Background Acute lymphoblastic leukemia (ALL) is aggressive cancer, especially in adults as only 20-40% is cured with current treatment regimens. Objectives The aim of this study is to evaluate prognostic factors and their effects on survival in ALL patients in the Northeast of Iran. Methods In a descriptive and retrospective study from 2009 to 2015, 48 ALL patients referred to hematology-oncology clinic. Age, sex, fever, blood group, type of ALL and consumption of amphotericin B, forms of cytogenetic, survival in the patients, WBC, hemoglobin, and platelet were checked in the first referral for every patient. The mean follow-up was 27.3 months in which 28 patients (59.3%) died. overall survival (OS) was plotted by GraphPad Prism 5 and the Log-rank test was used for analysis of survival with risk factors. Results The mean age for all the ALL patients at diagnosis was 32.3 years (range, 15-71 years), and 81.3% were male. Of all patients, 62.5% had fever and 25% consumed amphotericin B. 1-, 2-, 3-, 4-, 5-year OS rates were 62.2%, 52.7%, 40.6%, 39.1%, 22.2%, respectively. 75%, 29.2% and 39.6% of patients had WBC < 20 × 103/μl, Hb < 7 g/dL and platelet < 30 × 103/μL, respectively. There was a significant difference in survival based on age (P = 0.000). Conclusions Based on the results, age > 35 years is the most prognostic factor in ALL patients. Also, patients who received amphotericin B had lower life expectancy because these patients were suffering from fungal infection or due to lack of response to antibacterial drugs, they have been treated with amphotericin B.

急性淋巴细胞白血病(ALL)是一种侵袭性癌症，特别是在成人中，目前的治疗方案只有20-40%的治愈率。本研究的目的是评估伊朗东北部ALL患者的预后因素及其对生存的影响。方法对2009 - 2015年在血液学肿瘤学门诊就诊的48例ALL患者进行描述性和回顾性研究。年龄、性别、发烧、血型、ALL类型和两性霉素B的消耗、细胞遗传学形式、患者生存率、白细胞、血红蛋白和血小板在每个患者的第一次转诊时进行检查。平均随访27.3个月，其中28例(59.3%)死亡。采用GraphPad Prism 5绘制总生存率(OS)，采用Log-rank检验分析生存率与危险因素的关系。结果all患者诊断时平均年龄为32.3岁(15 ~ 71岁)，男性占81.3%。62.5%的患者有发热，25%的患者使用两性霉素b。1、2、3、4、5年总生存率分别为62.2%、52.7%、40.6%、39.1%、22.2%。WBC < 20 × 103/μl的占75%，Hb < 7 g/dL的占29.2%，血小板< 30 × 103/μl的占39.6%。不同年龄生存率差异有统计学意义(P = 0.000)。结论年龄0 ~ 35岁是影响ALL患者预后的最重要因素。此外，接受两性霉素B治疗的患者预期寿命较低，因为这些患者患有真菌感染或由于对抗菌药物缺乏反应，他们已经接受了两性霉素B治疗。

Background Recently, Chrysin, as a flavone, has revealed cancer chemo-preventive activity. The present experiment utilized the PLGA-PEG-chrysin complex, and free chrysin, to evaluation of the expression of miR-22, miR-34a and miR-126 in human gastric cell line. Objectives The purpose of this study was to examine whether nano encapsulating chrysin improves the anti-cancer effect of free chrysin on AGS human gastric cell line. Methods Properties of the chrysin encapsulated in PLGA-PEG nanoparticles were investigated by SEM, H NMR, and FTIR. The assessment of cytotoxicity on the growth of the human gastric cell line was carried out through MTT assay. After treating the cells with a prearranged amount of pure and encapsulated chrysin, RNA was extracted and the expressions of miR-22, miR-34a and miR-126 were measured by using real-time PCR. Results With regard to the amount of the chrysin loaded in PLGA-PEG nanoparticles, IC50 value was significantly decreased in nanocapsulatedchrysin, in comparison with free chrysin. This finding has been proved through the further increase of miR-22, miR-34a and miR-126 gene expression of nanocapsulatedchrysin, in comparison with free chrysin. Conclusions In this study, we revealed that the PLGA-PEG-chrysin is more effective than free chrysin in inhibiting the growth of human gastric cell line.

背景近年来，黄菊花素作为一种黄酮类化合物被发现具有肿瘤化学预防作用。本实验利用PLGA-PEG-chrysin复合物和游离chrysin来评价miR-22、miR-34a和miR-126在人胃细胞系中的表达。目的研究纳米包封金菊素是否能提高游离金菊素对AGS人胃癌细胞的抗癌作用。方法采用扫描电镜(SEM)、核磁共振(H NMR)、红外光谱(FTIR)等方法对聚乙二醇-聚乙二醇纳米颗粒包裹的杨菊素进行表征。采用MTT法对人胃细胞株生长进行了细胞毒性评价。用预先安排好的纯包膜的菊花素处理细胞后，提取RNA，用实时荧光定量PCR检测miR-22、miR-34a和miR-126的表达。结果在PLGA-PEG纳米颗粒的负载量下，纳米胶囊的IC50值与游离的相比显著降低。这一发现已经通过纳米胶囊化的白菊花素的miR-22, miR-34a和miR-126基因表达的进一步增加与游离白菊花素相比得到证实。结论在本研究中，我们发现PLGA-PEG-chrysin对人胃细胞系生长的抑制作用优于游离的chrysin。

Introduction Nasopharyngeal carcinoma among the children has been rare accounting for only 1% of all pediatric malignancies. Both genetic and environmental factors have contributed to the development of nasopharyngeal carcinoma. Among the children there was a higher rate of undifferentiated histology. The mean age of nasopharyngeal carcinoma diagnosis has been 11 years old age; and the most common site was nasopharynx. Palpable lymphadenopathy, dysphasia and neural defect were common associated signs. Case Presentation A 15-year-old boy has presented with a mass that located near by the heart in the left side of mediastinum with invasion to anterior mediastinum from two years ago. In biopsy, nasopharyngeal carcinoma, non-keratinizing type, has diagnosed while there was no involvement of nasopharyngeal region. Patient has treated by 70 Gy (2.0 Gy/fraction) radiotherapy plus concomitant chemotherapy with base of docetaxel. But the mass had no regression. Then, the patient has treated with Cisplatin 100 mg/m2 IV on days 1, 22, and 43 with radiation, then cisplatin 80 mg/m2 IV on day 1 plus fluorouracil (5-FU) 1000 mg/m2/day by continuous IV infusion on days 1 - 4 every 4wk for 3 cycles and after remission interferon beta has added to treatment for 6 months duration as a maintenance therapy. After 1 year follow up; the patient was in complete remission. In the course of therapy, only hypothyroidism has occurred. Conclusions Nasopharyngeal carcinoma in childhood, without nasopharyngeal involvement, initially could be detected in other sites such as pericardium. Also good results could be respected by cisplatin and 5-fluorouracil based neoadjuvant chemotherapy before radiotherapy plus interferon beta as a maintenance therapy in childhood aggressive nasopharyngeal carcinoma.

鼻咽癌在儿童中很少见，仅占所有儿童恶性肿瘤的1%。遗传和环境因素都是鼻咽癌发生的重要因素。在儿童中，未分化的组织学比例较高。鼻咽癌确诊的平均年龄为11岁;最常见的部位是鼻咽部。可触及的淋巴结病变、吞咽不良和神经缺损是常见的相关征象。病例介绍:一名15岁的男孩，两年前出现了位于心脏附近左侧纵隔的肿块，并侵犯了前纵隔。活检证实鼻咽癌为非角化型，未累及鼻咽区。患者接受70 Gy (2.0 Gy/分)放疗加多西紫杉醇基础化疗。但质量没有下降。然后，患者在第1、22、43天给予顺铂100mg /m2 IV放疗，第1天给予顺铂80mg /m2 IV加氟尿嘧啶(5-FU) 1000mg /m2/天连续静脉输注，第1 - 4天每4周持续静脉输注，持续3个周期，缓解后在治疗中加入干扰素β 6个月作为维持治疗。随访1年后;病人病情完全缓解。在治疗过程中，仅发生甲状腺功能减退。结论儿童鼻咽癌不累及鼻咽部，可在心包等其他部位发现。儿童侵袭性鼻咽癌放疗前以顺铂和5-氟尿嘧啶为基础的新辅助化疗加干扰素维持治疗也可获得良好的效果。

Background Sulfated Polysaccharides (SPs) possess spectrum of pharmacological and therapeutic properties that could attributed to their origins variation, chemical structures and biological activities. Various studies have shown the impact of SPs on proliferation in different cancer cell lines. Objectives In this study, we have evaluated the biological effects of λ-carrageenan, a highly SP, extracted from the red seaweed Laurencia papillosa, on MDA-MB-231 cancer cell line. Materials and Methods MDA-MB-231 cells have treated with λ-carrageenan, the viability and apoptosis have assessed by the appropriate florescent probes on flow cytometer. The expression levels of mRNA of apoptotic genes have detected by real-time PCR analysis. Results Our results have indicated that the signaling pathway of λ-carrageenan inhibited the proliferation of MDA-MB-231 cells by up-regulating the pro-apoptotic genes caspase-8, caspase-9, caspase-3 which have been resulting the increased levels of active caspase-3 protein. Furthermore, This SP had that capacity to disrupt the mitochondrial function by altering the bax/bcl-2 ratio of expression which has considered an important element in apoptosis induction. Conclusions The presented results have signposted that λ-carrageenan was a promising bioactive polymer which could be a potential candidate in preventing or treating breast cancer.

硫酸酸化多糖(SPs)具有广泛的药理和治疗特性，这可能归因于其来源、变异、化学结构和生物活性。各种研究表明，SPs对不同癌细胞系的增殖有影响。目的研究从紫菜中提取的高SP含量的λ-卡拉胶对MDA-MB-231癌细胞的生物学作用。材料与方法用λ-卡拉胶处理MDA-MB-231细胞，在流式细胞仪上采用合适的荧光探针检测细胞活力和凋亡情况。实时荧光定量PCR检测凋亡基因mRNA表达水平。结果λ-卡拉胶信号通路通过上调促凋亡基因caspase-8、caspase-9、caspase-3抑制MDA-MB-231细胞的增殖，从而导致caspase-3活性蛋白水平升高。此外，该SP具有通过改变bax/bcl-2表达比例来破坏线粒体功能的能力，而bax/bcl-2表达比例被认为是诱导凋亡的重要因素。结论λ-卡拉胶是一种很有前途的生物活性聚合物，可能是预防或治疗乳腺癌的潜在候选物。

Background Posttraumatic growth (PTG) refers to positive psychological change experienced as a result of the struggle with highly challenging life circumstances. PTG in cancer survivors is related to several psychosocial factors such as psychological hardiness and marital satisfaction. Objectives The purpose of this study was to examine the prediction of posttraumatic growth based on psychological hardiness and marital satisfaction. Patients and Methods A total of 120 women with breast cancer were recruited from several hospitals in Isfahan using convenience sampling. Participants completed the research questionnaires including the posttraumatic growth inventory (PTGI), the Ahvaz psychological hardiness scale and the Enrich’s marital satisfaction scale (EMS). Statistical analysis including means, standard deviation, Pearson’s correlation and multiple regression analysis were carried out using SPSS software (version 16). Results Results indicated that the majority of patients with cancer experienced posttraumatic growth. Findings also showed that psychological hardiness, marital satisfaction and longer time since diagnosis of cancer significantly predicted posttraumatic growth. Conclusions This study highlights the significant role of psychological hardiness and marital support in personal growth of breast cancer survivors.

Background: B cell chronic lymphocytic leukemia is one of the most frequent hematologic malignancies in the world. Cellular surface CD markers and serum Beta-2-microglobulin may be used as a prognostic tool in CLL patients.

Objectives: In the present study we introduce serum adenosine deaminase as a diagnostic marker in CLL.

Materials and methods: Blood samples were collected from B-CLL and healthy subjects. White blood cell, red blood cell and platelet count and blood Erythrocyte sedimentation rate was recorded and serum Beta-2-microglobulin, Lactate dehydrogenase and total ADA enzyme activity were determined.

Results: Serum ADA activity was significantly higher in patients group than that of controls. ADA had a significant and direct correlation with B2M, WBC, LDH and ESR. However, there was not any relation between ADA and the stages of disease. Diagnostic cut-off, sensitivity and specificity of the serum ADA test were 27.97 U/L, 91% and 94%, respectively.

Conclusions: A higher ADA activity in patients group and its correlation with CLL markers were seen in our study. High diagnostic value of serum ADA in our study suggests that it might be considered as a useful screening tool among the other markers in CLL.

背景：B细胞慢性淋巴细胞白血病是世界上最常见的血液系统恶性肿瘤之一。细胞表面CD标记物和血清β-2-微球蛋白可作为CLL患者的预后工具：在本研究中，我们将血清腺苷脱氨酶作为 CLL 的诊断指标：采集B-CLL和健康受试者的血样。记录白细胞、红细胞、血小板计数和红细胞沉降率，测定血清β-2-微球蛋白、乳酸脱氢酶和总 ADA 酶活性：结果：患者组的血清 ADA 活性明显高于对照组。ADA 与 B2M、WBC、LDH 和 ESR 有明显的直接相关性。但 ADA 与疾病的分期没有任何关系。血清 ADA 检测的诊断临界值、敏感性和特异性分别为 27.97 U/L、91% 和 94%：我们的研究发现，患者组的 ADA 活性较高，且与 CLL 标志物相关。在我们的研究中，血清 ADA 具有很高的诊断价值，这表明它可被视为 CLL 其他标志物中的一种有用的筛查工具。
