Disease-free survival of subgroups by N stage In stratified analysis by lymph node involvement, we also found an inferior DFS in 11 BRCA1 carriers (germline or somatic) than 165 non-carriers with a marginal significance in the patients without lymph node involvement (3-year DFS rate: 81.8%±11.6% vs. 95.9%±1.7%; log-rank P = 0.055; Fig 2C ).
