The Kaplan–Meier single-factor survival analysis showed that the OS-related variables were family history (P = 0.048), number of LN metastases (P < 0.001), presence of vascular tumor thrombus (P < 0.001), HER2 expression status (P = 0.025), and clinical stage (P < 0.001). Here, ERBB2 is linked to neoplasm.
