At a maximum follow up of 8 years (median 5 years 6 months) in a randomised trial of adjuvant tamoxifen versus no treatment as therapy for early breast cancer, a significant advantage persists for patients receiving 20 mg of tamoxifen daily for 2 years. This advantage is independent of menopausal status, stage, grade and ER status. Log hazard rate analysis fails to demonstrate a rebound effect on stopping the drug and suggests that more prolonged treatment might further improve results.
在一项辅助性他莫昔芬与不治疗作为早期乳腺癌治疗方法的随机试验中,对患者进行了最长8年的随访(中位随访时间为5年6个月),结果显示,接受每日20毫克他莫昔芬治疗2年的患者仍具有显著优势。这一优势与绝经状态、分期、分级和雌激素受体状态无关。对数风险率分析未能证明停药后有反弹效应,提示延长治疗时间可能会进一步改善治疗效果。
