ABSTRACT=<sec><title>Background</title><p>Poly (ADP-Ribose) Polymerase (PARP) inhibitors represent a novel class of drugs that hinder DNA repair mechanisms in tumor cells, leading to cell death. This systematic review aims to evaluate the effectiveness, safety, and potential adverse effects of PARP inhibitors (PARPi) in the management of patients with advanced lung cancer.</p></sec><sec><title>Materials and Methods</title><p>We conducted a comprehensive search for relevant studies in PubMed, Embase, Cochrane, and <ext-link ext-link-type="uri" xlink:href="http://ClinicalTrials.gov" xmlns:xlink="http://www.w3.org/1999/xlink">ClinicalTrials.gov</ext-link>. We extracted primary and secondary outcome measures, including progression-free survival (PFS), overall survival (OS), and adverse events (AEs), from the identified literature for subsequent meta-analysis and systematic review.</p></sec><sec><title>Results</title><p>This study encompassed twelve randomized controlled trials, involving 3,132 patients with advanced lung cancer. In comparison to non-PARPi treatments, the administration of PARPi significantly extended OS (hazard ratio (HR) = 0.90, 95% CI = 0.83–0.97, <italic>p</italic> = 0.006). However, the difference in PFS did not reach statistical significance.</p></sec><sec><title>Conclusion</title><p>In summary, therapies incorporating PARPi provide a degree of benefit by extending OS in patients with advanced lung cancer. Nonetheless, further trials are necessary to furnish additional evidence regarding the efficacy and safety of PARPi in the treatment of lung cancer.</p></sec><sec><p><bold>Systematic Review Registration:</bold><ext-link ext-link-type="uri" xlink:href="https://www.crd.york.ac.uk/PROSPERO/" xmlns:xlink="http://www.w3.org/1999/xlink">https://www.crd.york.ac.uk/PROSPERO/</ext-link>, identifier number: CRD42023424673.</p></sec>
