The purpose of this study was to determine the feasibility of using a tumor registry to recruit newly diagnosed survivors into a randomized controlled exercise trial and to discuss issues related to this recruitment strategy.
A tumor registry-based rapid ascertainment system was used to recruit breast cancer survivors into a 6-month home-based, telephone-administered intervention of moderate-to-vigorous intensity exercise or a usual care group.
468 newly diagnosed cases were identified. Of these, 50 women (15.4% of those for which screening calls were made) were enrolled in the study. Women were randomized, on average, 11 weeks after diagnosis (SD = 4.8). Sixty-four percent were randomized before beginning treatment or within the first week of treatment. Time required to obtain physician consent was the primary determinant of diagnosis-to-randomization latency. Enrolled women were more likely than nonenrolled women to be non-Hispanic White and to have a college degree (P < .05).
Tumor registries present a feasible means of recruiting breast cancer survivors before or early in adjuvant treatment. The success of recruiting survivors promptly after diagnosis is largely dependent on ability to rapidly obtain physician consent. Specific effort is needed to counteract self-selection effects that may lead to under-representation of minorities.
本研究旨在确定利用肿瘤登记系统招募新诊断幸存者参加随机对照运动试验的可行性,并讨论与该招募策略相关的问题。
采用基于肿瘤登记的快速确定系统,将乳腺癌幸存者招募到为期 6 个月的家庭式、电话管理的中度至剧烈强度运动干预组或常规护理组。
共确定了 468 例新诊断病例。其中,有 50 名女性(进行筛选电话的女性的 15.4%)参加了该研究。女性的随机分组平均在诊断后 11 周(SD=4.8)进行。64%的女性在开始治疗前或治疗的第一周内被随机分组。获得医生同意的时间是诊断到随机分组潜伏期的主要决定因素。入组的女性比未入组的女性更有可能是非西班牙裔白人且拥有大学学历(P<.05)。
肿瘤登记系统提供了一种在辅助治疗前或早期招募乳腺癌幸存者的可行方法。在诊断后迅速招募幸存者的成功在很大程度上取决于快速获得医生同意的能力。需要特别努力来克服可能导致代表性不足的自我选择效应。
