When tumor response was evaluated post-surgically using the Chevallier classification [19], we observed that the AMH decrease between AMH0 and Mid-CT (expressed in absolute values) was greater in patients with a pCR (Chevallier classes 1 and 2) than in those with residual disease (Chevallier classes 3 and 4) regardless of gBRCA status: − 30.10 [− 42.7; − 23.2] pmol/L vs − 12.7 [− 36.9; − 8.8] pmol/L (median [IQR]), p = 0.04. Here, AMH is linked to neoplasm.
