Small cell lung cancer (SCLC) is a malignant tumor with remarkable proliferative and invasive ability, which has very poor clinical prognosis due to lack of effective treatments. In recent years, researches on cells, animal models and tumor samples have promoted the identification of molecular subtypes of SCLC, discovered unique biological and clinical characteristics, and proposed potential specific therapeutic targets for different subtypes. This will encourage the development of more accurate therapeutic strategies towards SCLC, with a view to improving the prognosis of the patients. This article will review the current SCLC molecular subtypes, focus on the clinical characteristics and therapeutic strategies of different SCLC subtypes, and propose reasonable suggestions for the future treatment of SCLC. .
【中文题目：小细胞肺癌的分子分型及其治疗策略 的研究进展】 【中文摘要：小细胞肺癌（small cell lung cancer, SCLC）是一种具有极强增殖和侵袭能力的恶性肿瘤，由于缺乏有效治疗手段，临床预后差。近年来，对细胞、动物模型及肿瘤组织本身的研究推动了SCLC分子亚型的提出，并发现不同分子亚型的SCLC具有独特的生物学和临床特征及潜在的特异性治疗靶点，这将有助于为SCLC患者制定更精准的治疗策略，以期改善预后。本文拟对目前关于SCLC的分子分型进行综述，重点关注不同分子分型的SCLC的临床特征以及治疗策略，并提出未来SCLC治疗的合理建议。 】 【中文关键词：肺肿瘤；分子分型；临床特征；治疗】.
