2018年5月,发表在《J Natl Cancer Inst》的一项由美国科学家进行的研究,考察了早期乳腺癌化疗的使用和肿瘤科专家治疗建议的近期趋势。

背景:由于结局会随着时间改善,因此有关乳腺癌过度治疗的担心越来越多。然而,对近年来化疗使用和肿瘤专家治疗建议如何改变知之甚少。

方法:研究者调查了5080例2013~2015年诊断为乳腺癌的女性(应答率70%),通过两个监测、流行病学和最终结果注册(格鲁吉亚和洛杉矶)调查了接受化疗的情况及她们的肿瘤科医生的化疗建议。研究者调查了504名肿瘤主治医师(应答率60.3%),调查内容为在淋巴结阴性和淋巴结阳性病例的情况下的化疗建议。研究者对化疗使用和患者报告的肿瘤医生给出的建议进行了描述性统计学分析,并根据时间和临床因素使用了关于化疗使用的广义线性混合模型。所有统计学检验都是双侧的。

结果:分析样本为2926例I~II期、雌激素受体阳性、人表皮生长因子受体2阴性的乳腺癌患者。2013~2015年,保持其他因素不变的情况下,化疗使用估计从34.5%(95% 置信区间[CI]=30.8%~38.3%)降低至21.3%(95% CI=19.0%~23.7%,P<0.001)。对于淋巴结阴性/微转移患者,化疗使用从26.6%(95% CI=23.0%~30.7%)降低至14.1%(95% CI=12.0%~16.3%),对于淋巴结阳性患者,从81.1%(95% CI=76.6%~85.0%)降低至64.2%(95% CI=58.6%~69.6%)。淋巴结阴性/微转移患者21基因复发评分(RS)的使用未改变,淋巴结阳性患者RS使用的增加占到了化疗降低的1/3。控制了其他因素后,患者报告的肿瘤医生给出的化疗建议的报告从44.9%(95% CI=40.2%~49.7%)降低至31.6%(95% CI=25.9%~37.9%)。如果患者的偏好与他们的建议不一致,肿瘤科专家更可能使用RS(67.4%,95% CI=61.7%~73.0%,vs 17.5%,95% CI=13.1%~22.0%),并且医生会基于患者的偏好和RS结果调整他们的建议。

结论:对于淋巴结阴性/微转移和淋巴结阳性患者,接受化疗和肿瘤专家给出的化疗建议都随时间显着下降,实践指南未发生实质性改变。正在进行的试验结果对于证实该乳腺癌治疗方法的质量至关重要。
