《自然-医学》| 儿童肿瘤生存者应关注这类化疗带来继发性乳腺癌风险
这项研究汇总了欧洲和北美地区六项队列研究的患者数据,共纳入1946–2012年间17,903例女性原发性儿童癌症生存者(确诊时年龄≤21岁,确诊后存活≥5年),自其确诊起中位随访时间为24.9年。研究人员根据是否接受过蒽环类药物化疗或胸部放疗,以及具体蒽环类药物(阿霉素、柔红霉素或表阿霉素)和剂量将纳入人群分为多个亚组,通过对比各亚组发生继发性乳腺癌的情况来分析各蒽环类药物与继发性乳腺癌之间的相关性。

原文摘要(Abstract)
Anthracycline-based chemotherapy is associated with increased subsequent breast cancer (SBC) risk in female childhood cancer survivors, but the current evidence is insufficient to support early breast cancer screening recommendations for survivors treated with anthracyclines. In this study, we pooled individual patient data of 17,903 survivors from six well-established studies, of whom 782 (4.4%) developed a SBC, and analyzed dose-dependent effects of individual anthracycline agents on developing SBC and interactions with chest radiotherapy. A dose-dependent increased SBC risk was seen for doxorubicin (hazard ratio (HR) per 100 mg m-2: 1.24, 95% confidence interval (CI): 1.18-1.31), with more than twofold increased risk for survivors treated with ≥200 mg m-2 cumulative doxorubicin dose versus no doxorubicin (HR: 2.50 for 200-299 mg m-2, HR: 2.33 for 300-399 mg m-2 and HR: 2.78 for ≥400 mg m-2). For daunorubicin, the associations were not statistically significant. Epirubicin was associated with increased SBC risk (yes/no, HR: 3.25, 95% CI: 1.59-6.63). For patients treated with or without chest irradiation, HRs per 100 mg m-2 of doxorubicin were 1.11 (95% CI: 1.02-1.21) and 1.26 (95% CI: 1.17-1.36), respectively. Our findings support that early initiation of SBC surveillance may be reasonable for survivors who received ≥200 mg m-2 cumulative doxorubicin dose and should be considered in SBC surveillance guidelines for survivors and future treatment protocols.
