A review of 6109 mammograms representing 4332 patients seen over 4 years is presented. The American Cancer Society guidelines for mammography screening were followed. Forty-five percent of all tumors were nonpalpable; in 12% of these the lymph nodes were positive for cancer. In the group with palpable breast cancers, 62% had positive lymph nodes. Screening mammography results in an increased number of localization biopsies. Biopsy rates were compared with several series. Costs for mammography screening programs were reviewed and related to the cost of each breast cancer detected. In our series the cost per cancer detected was $13,000. This study provides evidence to justify the American Cancer Society guidelines.
本文回顾了4年期间4332例患者的6109份乳房X光片，遵循了美国癌症协会的乳房X光检查筛查指南。所有肿瘤中有45%触诊不到；其中12%的患者淋巴结有癌转移。在可触及乳腺癌组中，62%有阳性淋巴结。乳腺筛查性X光检查导致定位活检数量增加。将活检率与其他几个系列进行了比较。对乳房X光筛查项目的成本进行了评估，并与每例检测出的乳腺癌成本相关联。在我们的系列研究中，每例检测出的癌症成本为13,000美元。本研究为美国癌症协会的指南提供了合理依据。
