Patient-reported outcomes from a randomized trial of neoadjuvant atezolizumab-chemotherapy in early triple-negative breast cancer.

Patient-reported outcomes data assessing patients' experience of immunotherapy treatment burden in potentially curable early-stage triple-negative breast cancer (TNBC) are lacking. These patient-reported data inform clinical benefit and decision-making for adding atezolizumab to neoadjuvant chemotherapy in early-stage TNBC. IMpassion031 (NCT03197935) randomly assigned patients with stage II/III TNBC (T2-T4d primary tumors) to 5 cycles (4 weeks/cycle) of every 2-week neoadjuvant atezolizumab 840 mg or placebo with weekly nab-paclitaxel (3 cycles) followed by every 2-week dose-dense doxorubicin+cyclophosphamide (2 cycles).
