Using circulating tumor cell (CTC) count to guide the choice of first-line treatment—chemotherapy or endocrine therapy—improved overall survival (OS) compared with investigator’s choice of treatment for patients with metastatic, estrogen receptor (ER)-positive, HER2-negative breast cancer, according to results from the STIC CTC trial.

In patients with hormone receptor (HR)-positive, HER2-low or -negative, locally advanced or metastatic breast cancer resistant to aromatase inhibitors, the addition of the investigational first-in-class AKT inhibitor capivasertib (AZD5363) to fulvestrant (Faslodex) led to a statistically significant and clinically meaningful improvement in progression-free survival (PFS) compared with placebo plus fulvestrant.
