In an attempt to diagnose breast carcinoma as early as possible, a government-funded screening mammography program in British Columbia discovered 29 malignancies in the first 7,100 women screened. The program was carefully planned by a group consisting of representatives of all appropriate constituents. The screenees have demonstrated the anticipated increased frequency with increasing age and risk factors; in addition, the frequency of diagnosis is markedly lower in screenees who have had mammograms within the 2 previous years. Exclusive of equipment costs, amortization, and data processing, the cost per study is $33.81 (Canadian), resulting in a cost of $8,277.62 for each case diagnosed. This includes, for each study, an administrative fee of $1.00 as well as $1.00 devoted to continuing education for the reading radiologists. The success of the program has resulted in encouragement from the Health Ministry to expand rapidly throughout the Province, including use of a mobile van in more remote areas. Continued monitoring and peer review will ensure standard quality control in all of the screening facilities.
为了尽早诊断出乳腺癌，不列颠哥伦比亚省一项由政府资助的乳房X线筛查项目在最初筛查的7100名女性中发现了29例恶性肿瘤。该项目由所有相关部门的代表组成的小组精心策划。筛查对象呈现出随着年龄增长和风险因素增加而预期的发病率上升的情况；此外，在过去两年内做过乳房X线检查的筛查对象中，诊断频率明显较低。不包括设备成本、摊销和数据处理，每项检查的成本为33.81加元（加拿大），因此每诊断出一例病例的成本为8277.62加元。这其中，每项检查包括1加元的管理费以及1加元用于为阅片放射科医生提供继续教育。该项目的成功促使卫生部鼓励在全省迅速推广，包括在更偏远地区使用流动检查车。持续监测和同行评审将确保所有筛查设施的标准质量控制。
