For example, EGFR overexpression, which is associated with poor clinical outcome, is described in 15%-30% of BC cases [23], but in this study, which included patients with a poor outcome, it was only observed in one LB case, whose surgical specimen was diagnosed as TN. Despite the existence of anti-EGFR therapy, it would not have been used in this patient, because clinical trials have shown disappointing results in triple-negative BC. The gene discussed is EGFR; the disease is breast cancer.
