Patterns in survival can provide information about the burden and severity of cancer, help uncover gaps in systemic policy and program delivery, and support the planning of enhanced cancer control systems. The aim of this paper is to describe the one-year survival rates for breast cancer in two populations using population-based cancer registries: Ardabil, Iran, and British Columbia (BC), Canada.
All newly diagnosed cases of female breast cancer were identified in the Ardabil cancer registry from 2003 to 2005 and the BC cancer registry for 2003. The International Classification of Disease for Oncology (ICDO) was used for coding cancer morphology and topography. Survival time was determined from cancer diagnosis to death. Age-specific one-year survival rates, relative survival rates and weighted standard errors were calculated using life-tables for each country.
Breast cancer patients in BC had greater one-year survival rates than patients in Ardabil overall and for each age group under 60.
These findings support the need for breast cancer screening programs (including regular clinical breast examinations and mammography), public education and awareness regarding early detection of breast cancer, and education of health care providers.
生存模式可以提供癌症负担和严重程度的信息，有助于揭示系统政策和项目实施方面的差距，并为加强癌症控制体系规划提供支持。本文旨在使用基于人群的癌症登记处，描述伊朗阿瓦士和加拿大不列颠哥伦比亚省（BC）两个地区乳腺癌患者的一年生存率。
阿瓦士癌症登记处从 2003 年至 2005 年以及不列颠哥伦比亚癌症登记处从 2003 年确定了所有新诊断的女性乳腺癌病例。国际肿瘤疾病分类（ICDO）用于对癌症形态和位置进行编码。生存时间从癌症诊断到死亡确定。使用每个国家的寿命表计算特定年龄的一年生存率、相对生存率和加权标准误差。
BC 的乳腺癌患者的一年生存率总体上高于阿瓦士，而且在每个 60 岁以下的年龄组中都更高。
这些发现支持开展乳腺癌筛查计划（包括定期临床乳房检查和乳房 X 光检查）、开展公众教育和提高对乳腺癌早期检测的认识、以及对医疗保健提供者进行教育的必要性。
