Fig. 4From: Identification of mutation patterns and circulating tumour DNA-derived prognostic markers in advanced breast cancer patientsSurvival analyses of (A) PFS and (B) OS among the three IHC subtypes. C Comparison of bTMB among the three IHC subtypes. D Comparison of bTMB between HER2 + drug-sensitive and drug-resistant samples. The black lines represent the median of each group. Survival analyses of (E) PFS and (F) OS between patients with low and high bTMB. PFS, progression-free survival; OS, overall survival; IHC, immunohistochemistry; bTMB, blood-based tumour mutation burden; HER2 + , human epidermal growth factor receptor 2-positiveBack to article page
