Ursprung der Roten Flagge

Begriffsbestimmung	Homologous Recombination Deficiency (HRD)-positive high-grade serous ovarian carcinoma (BRCA1/2 mutation OR Genomic Instability Score ≥42). PARPi maintenance after platinum-based induction is treatment-defining: niraparib (PRIMA — mPFS 21.9 vs 10.4 mo HRD-pos), olaparib + bevacizumab (PAOLA-1 — mPFS 37.2 vs 17.7 mo HRD-pos).
Klinische Richtung	Intensivierung
Kategorie	high-risk-biology
Schaltet Algorithmus	ALGO-OVARIAN-ADVANCED-1L, ALGO-OVARIAN-2L

Anmerkungen

HRD assays: Myriad myChoice CDx (companion for olaparib + bev, niraparib), FoundationOne CDx HRD. GIS captures BRCAness (LOH + TAI + LST signatures) in tumors WT for BRCA1/2. HRD-negative HGSC has minimal PARPi maintenance benefit (PRIMA mPFS 8.1 vs 5.4 mo) — bev maintenance preferred. Coexists with RF-OVARIAN-BRCA-MUT-ACTIONABLE (BRCA-mut subset is HRD-positive by definition); RF-OVARIAN-HRD-ACTIONABILITY is the older composite version.
