ERBB2 and breast cancer: Low IGSF10 expression was significantly correlated with a shorter OS of patients with basal (HR = 0.44, 95% CI [0.22–0.86], P = 0.013), luminal A (HR = 0.47, 95% CI [0.25–0.88], P = 0.017), and HER2+ (HR = 0.28, 95% CI [0.09–0.81], P = 0.012) breast cancer subtypes (Figs. 3B–3E).
