摘要

Small cell lung cancer(SCLC)is a common pathological type of primary lung cancer originating from the bronchial mucosa or gland.SCLC is characterized by rapid growth,high degree of malignancy,and early metastasis,which poses a great threat to patients5 safety and quality of life,SCLC can be divided into two stages:localized disease and extensive disease.For limited-disease small cell lung cancer(LD-SCLC),radiotherapy and chemotherapy are often used in clinical treatment.In recent years,there are several new advances in the clinical treatment of SCLC,including the improvement of radiotherapy and chemotherapy methods,compatibility of first-line and second-line drugs,as well as immune-targeted therapy.This article discusses the current status of clinical treatment and the research progress of LD-SCLC in the past five years.
