Abstract:

Small cell lung cancer (SCLC) is a rapidly developing malignant tumor,which is highly heterogeneous and prone to drug resistance,and the prognosis is usually poor. Poly ADP-ribose polymerase (PARP) inhibitors target the DNA damage response pathway,preventing DNA repair,thereby exerting anti-tumor effects. Currently,PARP inhibitors are used as monotherapy or in combination with DNA-damaging agents or immune checkpoint inhibitors in the treatment of SCLC. Although the current research results are limited,it can be seen that PARP inhibitors may be a breakthrough in the targeted therapy of SCLC.

Key words: Small cell lung carcinoma, Poly(ADP-ribose) polymerase inhibitors, DNA repair, Molecular targeted therapy, Targeting preparation
