BACKGROUND Radium-223 dichloride (Ra-223) is a targeted alpha therapy that induces localized cytotoxicity in bone metastases. We evaluated the efficacy and safety of Ra-223 plus hormonal therapy in hormone receptor-positive (HR+), bone-dominant metastatic breast cancer. METHODS In this single-center phase II study, 36 patients received Ra-223 (55 kBq/kg intravenously every 4 weeks) up to 6 cycles with endocrine therapy. The primary objective was to determine the clinical disease control rate at 9 months. Secondary objectives were to determine (a) tumor response rate at 6 months, (b) progression-free survival (PFS) durations, and (c) safety. RESULTS The median number of prior systemic treatments for metastatic disease was 1 (range, 0-4). The disease control rate at 9 months was 49%. The tumor response rate at 6 months was 54% (complete response, 21%; partial, 32%). The median PFS was 7.4 months (95% CI, 4.8-not reached [NR]). The median bone-PFS was 16 months (95% CI, 7.3-NR). There were no grade 3/4 adverse events. CONCLUSIONS Ra-223 with hormonal therapy showed possible efficacy in HR+ bone-dominant breast cancer metastasis, and adverse events were tolerable. We plan to further investigate the clinical application of Ra-223 in these patients. (NCT02366130).

二氯化镭-223联合激素疗法治疗激素受体阳性,以骨为主的转移性乳腺癌的II期研究。

背景技术二氯化镭223(Ra-223)是一种定向的α疗法,可在骨转移中诱导局部细胞毒性。我们评估了Ra-223联合激素治疗在激素受体阳性(HR +),以骨为主的转移性乳腺癌中的疗效和安全性。方法在该单中心II期研究中,有36例患者接受了Ra-223(每4周静脉滴注55 kBq / kg),最多接受6个周期的内分泌治疗。主要目标是确定9个月时的临床疾病控制率。次要目标是确定(a)6个月时的肿瘤缓解率,(b)无进展生存期(PFS)持续时间和(c)安全性。结果先前对转移性疾病进行全身治疗的中位数为1(范围0-4)。9个月时的疾病控制率为49%。6个月时的肿瘤缓解率为54%(完全缓解,21%; 部分(32%)。PFS中位数为7.4个月(95%CI,4.8未达到[NR])。中位骨PFS为16个月(95%CI,7.3-NR)。没有3/4级不良事件。结论Ra-223激素治疗显示出在HR +骨为主的乳腺癌转移中可能的疗效,并且不良事件是可以忍受的。我们计划进一步研究Ra-223在这些患者中的临床应用。(NCT02366130)。
