| Mechanism Description | We show that clonal evolution occurs frequently during treatment, reflecting substantial sub-clonal complexity in breast cancer that has progressed after prior endocrine therapy. RB1 mutations emerged only in the palbociclib plus fulvestrant arm and in a minority of patients (6/127, 4.7%, p=0.041). New driver mutations emerged in PIK3CA (p=0.00069) and ESR1 after treatment in both arms, in particular ESR1 Y537S (p=0.0037). Evolution of driver gene mutations was uncommon in patients progressing early on palbociclib plus fulvestrant but common in patients progressing later on treatment. These findings inform future treatment strategies to address resistance to palbociclib plus fulvestrant. | ||||||||||||
