Results from the randomized trial underway in the Health Insurance Plan of Greater New York to determine the efficacy of periodic screening with mammography and palpation of the breast have been examined to determine the effect of screening on racial differences in breast cancer survival rates. Consistent with experience in general populations, the control group showed a lower five-year survival rate among non-White women with breast cancer than among White women. In the study group, 65 per cent of whom participated in the screening program, there was no differential in the survival rates of the two racial groups. The elimination of the unfavorable status among non-Whites through screening does not appear to be explained by various artifacts explored. Secondary prevention measures may offer the possibility of reducing or closing the gap in breast cancer survival rates between White and non-White women.
正在纽约大健康保险计划中进行的一项随机试验，旨在确定定期乳房X光检查和乳房触诊的疗效，其结果已被研究，以确定筛查对乳腺癌生存率种族差异的影响。与一般人群的经验一致，对照组中患乳腺癌的非白人女性的五年生存率低于白人女性。在研究组中，65%的人参与了筛查项目，两个种族群体的生存率没有差异。通过筛查消除非白人中的不利状况，似乎无法用所探讨的各种假象来解释。二级预防措施可能提供缩小或消除白人女性与非白人女性乳腺癌生存率差距的可能性。
