Progress of PARP inhibitors in targeted therapy of small cell lung cancer / 国际肿瘤学杂志

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.
