Small cell lung cancer (SCLC) is a highly aggressive and fatal malignant tumor. It has the characteristics of complex etiology, low differentiation, high malignancy, fast growth, strong invasiveness, early metastasis and acquired drug resistance, resulting in poor prognosis. In recent years, with the gradual deepening understanding on the molecular mechanism of SCLC and multi-omics data, it is proposed that molecular typing can be carried out according to the differential expression of key transcription factors, including SCLC-A, SCLC-N, SCLC-P and SCLC-I subtypes. Molecular typing of SCLC and its clinical application will help doctors to further optimize the detailed diagnosis and treatment plan of SCLC patients, so as to prolong the survival time and improve the quality of life of patients. .
【中文题目：小细胞肺癌分子分型研究进展】 【中文摘要：小细胞肺癌（small cell lung cancer, SCLC）是一种极具侵袭性和致命性的恶性肿瘤，具有病因复杂、分化程度低、恶性程度高、生长速度快、侵袭性强、转移早和获得性耐药等特点，导致患者的预后普遍较差。近年来，随着人们对SCLC发生发展分子机制研究的逐渐深入和多组学数据的深入挖掘，提出可以按照细胞内关键转录因子的差异表达进行分子分型，包括SCLC-A、SCLC-N、SCLC-P和SCLC-I等亚型。对SCLC进行分子分型研究并应用于临床，将有助于提高医生对SCLC患者的详细诊断和治疗方案的进一步优化，从而延长患者生存时间，提高患者生活质量。 】 【中文关键词：肺肿瘤；分子分型；疾病治疗；诊断】.
