Abstract

棘皮动物微管相关蛋白4(echinoderm microlubule-associated protein-like 4, EML4)和间变淋巴瘤激酶基因(anaplastic lymphoma kinase, ALK)可发生断裂后融合为EML4-ALK基因。对于EML4-ALK阳性非小细胞肺癌(non-small cell lung cancer, NSCLC),一代至三代的ALK抑制剂的使用已显示出显著疗效,很多患者可以从药物治疗中实现长期获益,部分患者在优化的治疗模式下可取得超过7年的长期生存。本例患者为EML4-ALK融合基因阳性肺腺癌,治疗结局却明显不同于其他EML4-ALK融合基因阳性肺癌患者,经过一代至三代ALK抑制剂靶向治疗和化学治疗疾病进展快,耐药时间短,生存期短,获益有限。患者2019年7月15日开始先后口服克唑替尼、色瑞替尼、劳拉替尼靶向治疗,行贝伐珠单抗联合培美曲塞、卡铂化疗2个疗程,于2020年9月10日患者死亡,生存期15个月。同时治疗中表现出ALK抑制剂的常见不良反应。本文分析本例患者的治疗疗效及治疗困境,为EML4-ALK融合基因阳性肺癌患者治疗提供探索方向。

The echinoderm microtubule associated protein-like 4 (EML4) and anaplastic lymphoma kinase (ALK) were fractured and fused to become EML4-ALK. Most of these EML4-ALK-positive non-small cell lung cancer patients respond well to the ALK inhibitor. Many patients can benefit from drug target therapy for a long time, and some patients can achieve long-term survival of more than 7 years under the optimized treatment mode. This patient has lung adenocarcinoma positive for EML4-ALK fusion gene, but the treatment outcome is obviously different from that of other patients with lung cancer positive for EML4-ALK fusion gene. After the first to third generations of ALK inhibitor targeted therapy and chemotherapy, the disease progresses rapidly, the drug resistance time is short, the survival time is short, and the benefit is limited. The patient received targeted therapy of Crizotinib, Ceritinib and Lorlatinib successively from July 15, 2019, followed by two chemotherapy courses of Bevacizumab combined with Pemetrexed and Carboplatin. The patient died on September 10, 2020, with a survival of 15 months. At the same time, the treatment showed common adverse reactions of ALK inhibitors. This paper analyzed the therapeutic effect and treatment dilemma of this patient, and provided an exploration direction for the treatment of patients with EML4-ALK fusion gene positive lung cancer.
