We investigated time trends and factors associated with the use of cardiac imaging among women with early-stage breast cancer prior to the initiation of treatment. Of 11,732 women ages 24–64, diagnosed with stage I–III breast cancer in 2006–2011, 2550 (22%) received anthracycline-based chemotherapy. Baseline cardiac imaging was used in 79% of patients receiving anthracyclines and increased over time. Of 2277 (20%) women who received non-anthracycline therapy, 16% received cardiac imaging. Women receiving cardiac imaging in non-anthracycline therapy group were more likely to have higher cardiovascular risk, as well as higher cancer stage and worse histological tumor grade suggesting that results of imaging might have influenced the choice of cancer therapy. Our findings indicate the need for cardio-oncology collaboration in identification and treatment of women at high risk for adverse oncology and cardiovascular outcomes.

对刚诊断出乳腺癌的女性进行心脏成像的趋势。

我们调查了在开始治疗之前患有早期乳腺癌的女性中心脏成像使用的时间趋势和相关因素。在2006-2011年诊断为I-III期乳腺癌的11,732名年龄在24-64岁的女性中，有2550名（22％）接受了以蒽环类为基础的化疗。在接受蒽环类药物治疗的患者中，有79％的患者使用了基线心脏成像，并且随着时间的推移，基线基线成像显着增加。在接受非蒽环类药物治疗的2277名女性中（20％），有16％接受了心脏成像。非蒽环类药物治疗组接受心脏影像学检查的女性更有可能具有更高的心血管风险，以及癌症分期更高和组织学肿瘤分级更差，这表明影像学检查结果可能影响了癌症治疗的选择。
