There were also indications for prognosis being worst for patients with TN SDBC (HR = 3.78, 95% CI 0.44–32.37, compared to luminal-type SDBC), though the difference from HER2 + cancer was not significant (HR = 3.27, 95% CI 0.63–16.87, for HER + relative to luminal-type cases). The gene discussed is ERBB2; the disease is cancer.
