...pts with BRCA homozygous deletion or rearrangement had significantly longer DOR than pts with other mutation types (median 3.5 vs 0.6 y; HR = 0.30; p = 0.024)....Ten of the 13 long-term responders with BRCA wild-type OC had high genome-wide LOH (≥16% LOH), a genomic scar indicative of homologous recombination deficiency, including OC associated with BRCA1 hypermethylation (n = 2) and RAD51C/D mutations (n = 2).
