三阴性乳腺癌术前洛铂化疗效果
编者按:由于三阴性乳腺癌对内分泌激素疗法或HER2靶向疗法的效果不佳,故目前局部治疗(手术、放疗)前后的全身治疗仍以化疗为主。根据既往研究发现,大约六分之一的三阴性乳腺癌患者术前接受标准新辅助化疗方案(多西他赛+表柔比星)可能获得病理学完全缓解。将铂类(顺铂、卡铂)加入标准新辅助化疗方案,可能提高病理学完全缓解。不过,将洛铂加入标准新辅助化疗方案的效果尚不明确。
2018年2月26日,英国《自然》旗下《自然通讯》在线发表中国人民解放军陆军军医大学第一附属医院(第三军医大学西南医院)乳腺疾病中心的随机非盲II期研究报告,对洛铂加入多西他赛+表柔比星方案的影响进行了评价。
该单中心随机非盲II期研究于2014年1月~2017年2月入组I~III三阴性乳腺癌术前患者125例,随机接受多西他赛+表柔比星(63例)或多西他赛+表柔比星+洛铂(62例),其中60例、61例患者完成所有疗程。
结果发现,加用与不用洛铂相比:
有效性
乳房腋窝病理学完全缓解率:38.7%比12.7%(双侧P=0.001)
总体(完全+部分)缓解率:93.5%比73.0%(双侧P=0.003)
安全性
3~4级贫血发生率:52.5%比10.0%
3~4级血小板减少:34.4%比1.7%
因此,上述结果表明,洛铂加入多西他赛+表柔比星新辅助化疗方案,可以提高三阴性乳腺癌的乳房腋窝病理学完全缓解率和总体缓解率,但是副作用增加。

Currently, one sixth of triple-negative breast cancer (TNBC) patients who receive docetaxel (T) and epirubicin (E) as neoadjuvant chemotherapy achieve a pathologic complete response (pCR). This study evaluates the impact of adding lobaplatin (L) to the TE regimen. Here, we show data from 125 patients (63 TE and 62 TEL patients). Four patients did not complete all the cycles. Two-sided P values show that the addition of L (38.7% vs. 12.7%, P=0.001) significantly increases the rate of pCR in the breast and the axilla (TpCR) and the overall response rate (ORR; 93.5% vs. 73.0%, P=0.003). The occurrence of grade 3-4 anemia and thrombocytopenia is higher in the TEL group (52.5% vs. 10.0% and 34.4% vs. 1.7% respectively). These results demonstrate that the addition of L to the TE regimen as neoadjuvant chemotherapy improves the TpCR and the ORR rates of TNBC but with increased side effects.
