Abstract: Small cell lung cancer(SCLC),one of the histological subtypes of lung cancer,is characterized by high proliferation,early metastasis,susceptibility to drug resistance and recurrence.For several years,SCLC has always been regarded as a homogeneous disease,treated with a unified radiotherapy and chemotherapy strategy.Despite significant early therapeutic effects,drug resistance and recurrence occur quickly,and there is a lack of satisfactory treatment results,which may be due to insufficient understanding of the tumor heterogeneity of SCLC at present.Recently,the concept of SCLC molecular subtype based on the definition of relatively high expression of lineage transcription factors has been proposed in preclinical studies.This article mainly elaborates on the current status and latest findings of SCLC molecular subtype,emphasizing the potential problems that molecular typing may encounter in clinical practice,aiming to promote understanding of the research progress of molecular subtype in SCLC.
