Fig. 4From: Clinical and genetic risk factors for Fulvestrant treatment in post-menopause ER-positive advanced breast cancer patientsctDNA gene mutations in 16 individual Fulvestrant users. 5 patients received second-line Fulvestrant treatment (a), and 11 patients received third-line or higher line Fulvestrant treatment (b). Dark red represents the most frequent mutated genes and dark blue represents the rarest mutations. If the mutated genes appeared at the same frequency, they are ranked in alphabetic orderBack to article page
