摘要: Abstract Background Poly (ADP-ribose) polymerase-inhibitors (PARPis) showed antitumour activity in BRCA1/2-mutated cancers, with more heterogeneous outcomes tumours harbouring mutations that impair other genes involved the DNA homologous recombination repair (HRR) or wild-type (wt). Methods We conducted a systematic review and meta-analysis to better assess role of PARPis treatment metastatic solid tumours, without BRCA1/2 mutations. The primary end-point was progression-free survival (PFS). secondary end-points were overall response rate (ORR) (OS). A random-effects model applied. Results Twenty-nine studies (8,839 patients) included. PFS significantly improved (hazard ratio [HR]: 0.59, 95% confidence interval [CI]: 0.51–0.68, p Conclusion Our results confirm efficacy already approved PARPi-based treatments BRCA1/2-mutant support their also BRCA-independent HRR-deficient suggest potentially broader some wt perhaps appropriate therapeutic partners. Prospective are warranted.
