Description

Steven David and a large team report the AZTEC trial in 2026, a randomized phase II study pairing focused radiation with the immunotherapy drug atezolizumab in advanced triple-negative breast cancer. Lab evidence hints radiation can wake up body-wide anti-tumor responses, though the best radiation schedule was unknown. Fifty-four women received either one large dose or three smaller doses.

Median time without disease worsening was 2.5 months for the single-dose arm and 3.1 months for the multi-dose arm, too close to separate. Neither arm beat the two-month benchmark set in advance. Benefit lasting at least 24 weeks appeared in about a fifth to a quarter of patients, all with limited spread. Side effects were similar.
