title: Survival Rate of Breast Cancer in Iran: A Meta-Analysis
abstract: Background: There has not been a general estimation about survival rates of breast cancer cases in Iran. Therefore,
  the present study aimed to assess survival using a meta-analysis. Materials and Methods: International credible
  databases such as Scopus, Web of Science, PubMed, Science direct and Google Scholar and Iranian databases such
  as Magiran, Irandoc and SID, from 1997 to 2015 were searched. All articles covering survival rate of breast cancer
  were entered into the study without any limits. Quality assessment of the articles and data extraction were performed
  by two researchers using the modified STROBE checklist, which includes 12 questions. Articles with scores greater
  than 8 were included in the analysis. A limitation of this meta-analysis was different methods for presenting of results
  in the papers surveyed. Results: A total of 21 articles with a sample of 12,195 people were analyzed. The one-year,
  three-year, five-year and ten-year survival rates of breast cancer in Iran were estimated to be 95.8% (94.6-97.0), 82.4%
  (79.0-85.8), 69.5% (64.5-74.5), 58.1% (39.6-76.6), respectively. The most important factors affecting survival of breast
  cancer were age, number of lymph nodes involved, size of the tumor and the stage of the disease. Conclusion: The
  five- and ten- year survival rates in Iran are lower than in developed countries. Conducting breast cancer screening
  plan support (including regular clinical examination, mammography), public training and raising awareness should be
  helpful in facilitating early diagnosis and increasing survival rates for Iranian women.
