| RAD51C del | ovarian cancer | sensitive | Saruparib | Preclinical - Cell culture | Actionable | In a preclinical study, Saruparib (AZD5305) inhibited colony formation in an ovarian cancer cell line with RAD51C deletion in culture (PMID: 35929986). | 35929986 |
| RAD51C del | ovarian cancer | predicted - sensitive | unspecified PARP inhibitor | Case Reports/Case Series | Actionable | In a clinical study, PARP inhibitor monotherapy (niraparib (n=1), olaparib (n=5) or rucaparib (n=2)), resulted in a median progression-free survival (PFS) of 25.4 mo and an overall survival (OS) of 51.8 mo in ovarian cancer patients with homozygous deletion of homologous recombination repair (HRR) genes (n=8) including RAD51C (n=1), compared to a median PFS of 4.9 mo and OS of 18.5 mo in patients without HRR gene alterations (n=198) (PMID: 42133897). | 42133897 |
