Clinicopathological characteristics of breast cancer patients with NOD2 mutation according to age.

Introduction The purpose of the present study was to characterise patients with breast cancer (BC) and NOD2-mutation (age ≥ 50 years) according to their clinicopathological factors or family history. Patients aged ≥ 50 years were compared with the control group and with NOD2-mutation carriers aged 50 years of age. In NOD2-mutation carriers aged ≥ 50 years, the presence of larger tumour size, G3, or HER2 overexpression were lower compared with younger patients with NOD2 mutation.
