小细胞肺癌的分子分型及其治疗策略的研究进展

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.
