1例晚期ALK阳性肺鳞癌多学科临床决策探讨

Multidisciplinary treatment of advanced ALK-positive squamous cell lung carcinoma

间变淋巴瘤激酶(anaplastic lymphoma kinase,ALK)融合多见于肺腺癌这一病理类型,发生率为5%~7%。由于晚期非小细胞肺癌存在肿瘤异质性,肺鳞癌合并ALK融合亦有发生。多学科协作(multidisciplinary team,MDT)体系结合不同专业建议和循证医学理念,为复杂情况提供个性化治疗建议,尤其适合相对复杂的病案个例。本研究分享1例2022年12月天津医科大学肿瘤医院收治的肺鳞癌ALK基因融合患者MDT诊疗过程。患者初诊为Ⅲb期,序贯放化疗后快速进展,发生肝转移及脑转移,基因检测提示ALK融合,后续给予靶向药物洛拉替尼治疗,患者病灶缩小,治疗效果评估为疾病稳定(stable disease,SD)至今。

Anaplastic lymphoma kinase(ALK)fusion is commonly observed in lung adenocarcinoma,with an incidence rate of 5%-7%.Due to the tumor heterogeneity in advanced non-small cell lung cancer,ALK fusion can also occur in lung squamous cell carcinoma.A multidisciplinary team(MDT)combines various professional opinions and evidence-based medical principles to provide personalized treatment recommendations,particularly for complex cases.This study presents the MDT diagnostic and treatment approach for a patient with lung squamous cell carcinoma with an ALK mutation.Following initial diagnosis at stageⅢB,the patient exhibited rapid disease progression with liver and brain metastases after sequence chemoradiotherapy.After genetic testing revealed ALK fusion,the patient was treated with the ALK inhibitor,lorlatinib,which resulted in tumor regression and a persistent partial response.
