This medicine might decrease the risk of breast cancer. The main objective of this article was to determine the breast cancer risk in diabetic patients and its association with metformin and sulfonylurea. Evidence Acquisition: In order to gather evidences, main databases (MEDLINE, PubMed, Cochrane library, Science Direct, Trip, Google Scholar, Institute of Scientific Information (ISI), SCOPUS and EMBASE) as well as relevant websites have searched without time limitation up to June 2015. We have searched with appropriate keywords and strategies. After quality assessment of studies, consequences of risk and mortality for breast cancer have extracted. RevMan and comprehensive meta-analysis software has used, if needed, for meta-analysis. Results: A total of 423 studies, 352 studies have entered firstly and 11 studies have selected after final review. According to the signifi- cance of heterogeneity (I 2 = 94%) in these studies, meta-analysis have scrutinized by step by step removing the studies to investigate the reason of heterogeneity. So the relative risk of breast cancer was significant in favor of metformin (RR: 0.63, 95% CI (0.56 - 0.70), Pv < 0.001). Conclusions: In this study, we have concluded that the incidence of breast cancer in patients with type 2 diabetes who have used metformin might be less than who have used sulfonylurea. However, this finding should consider carefully and needed to be con- firmed with further studies.","PeriodicalId":73510,"journal":{"name":"Iranian journal of cancer prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68181872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic resonance imaging (MRI) revealed a large pituitary adenoma caused tight stenosis of right internal carotid.

There was not any sign of apoplexy at the time of admission and the patient has not shown a history of pituitary adenoma. The patient then has undergone an endonasal transsphenoidal resection because of this nonfunctional pituitary adenoma.

Tongue is a main segment of oral cavity and malignant lesions of this region accounts for nearly 30% of all oral cancers. Objectives In the present study, we evaluated the pattern of tongue cancer in Iranian population and compared these findings with those previously reported in the other countries. Methods In this multicenter, retrospective cross-sectional study recorded cases of the malignant tongue tumors in the cancer research center (CRC) of Shahid Beheshti University of Medical Sciences were extracted. The patient records and their microscopic reports were retrieved from the archives and age, sex and microscopic types were evaluated. It is to be noted that the CRC has been serving as a cancer registry center for major hospitals all over the country since the year of 2003. Thus, the obtained statistics are highly reliable. Results During the years 2003 to 2008, a total number of 952 new cases of the tongue cancer were recorded in the CRC. Most cases are diagnosed in the sixth and seventh decades of life. 450 cases (47.2%) occurred in men and 489 cases (51.36%) in women. Four different types of malignant lesions (epithelial, salivary gland, hematopoietic and mesenchymal) were diagnosed. Epithelial tumors were the most prevalent malignancies (93%) of which squamous cell carcinoma (SCC) made up 87.39% of all lesions. Salivary gland tumors had the second place with 3.15% of the total lesions. Conclusions In Iranian population, squamous cell carcinoma is the most prevalent malignancy of tongue and it is notable that the ratio of female to male population was equal. These lesions were prevalent in the sixth and seventh decades of life. Thus screening examination of tongue by dentist especially in elderly patients is necessary for early detection of cancerous lesions.","PeriodicalId":73510,"journal":{"name":"Iranian journal of cancer prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68181165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":73510,"journal":{"name":"Iranian journal of cancer prevention","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68182348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
