尼妥珠单抗联合紫杉醇及顺铂用作食管鳞状细胞癌的一线治疗:单中心前瞻性临床试验的最终结果

摘要号:#4070

第一作者:陆明,北京大学肿瘤医院消化肿瘤内科

背景: 尼妥珠单抗(N)是一种人源化抗EGFR单克隆抗体。我们进行了一项前瞻性单组开放性II期研究评价紫衫醇(T)/顺铂(C)/尼妥珠单抗(N)作为进展期ESCC一线治疗的疗效和安全性。 

方法:病理确诊无法切除的局部-区域进展期或转移性ESCC患者接受TPN方案治疗:尼妥珠单抗 200mg 1/周,紫杉醇175mg/m2(d1)和顺铂30mg/m2(d1和d2),每3周1个周期,共6个周期。 局部-区域进展期病变的定义是肿瘤灶局限于1个放疗野,没有脏器转移。转移性病变的定义是超过1个放疗野的脏器(肝、肺等)转移或淋巴结转移。4个周期的TPN治疗后可进行放射治疗。主要终点是客观有效率(ORR)和安全性。次要终点是无进展生存(PFS)和总体生存(OS)。

结果2011至2013年纳入了59 名患者,56名符合要求。29名患者为局部-区域进展期病变,27名患者为转移性病变。总体RR 为 51.8%(29/56),DCR为 92.9%(52/56)。中位随访时间24 个月时,33名患者出现病情进展,其中22名患者为转移性病变。转移性病变和局部-区域进展期病变患者的中位PFS为8.2个月 (95% CI 5.3 -11.2个月)和大于23个月(95% CI:9.0 -37.1)。转移性病变患者的总体生存为13.9 个月 (95% CI:6.8-21.2)。最为常见的3/4 级不良反应为中性粒细胞减少(58.9%)、白细胞减少(32.1%)、恶心/呕吐(7.1%)、纳差(5%)。3.6%的患者出现中性粒细胞减少伴发热。没有出现化疗相关死亡。

结论:与既往研究中发表的其它方案相比,TPN 作为一线化疗方案在进展期ESCC患者中是更为有效的治疗选择。标准化疗时加用尼妥珠单抗抗EGFR治疗耐受良好,没有严重不良反应。临床试验信息:NCT01336049.
