ASCO China Voice | Professors Claudio Vernieri & Man Li: PALMARES-2 Highlights the Potential of CDK4/6 Inhibitor Beyond Progression and Combined Local Therapy
At the 2026 ASCO Annual Meeting, Professor Claudio Vernieri from the Fondazione IRCCS Istituto Nazionale dei Tumori (Italy) presented the key findings of the PALMARES-2 study. Among patients with HR+/HER2− metastatic breast cancer, only about 20% continued first-line endocrine therapy (ET) plus a CDK4/6 inhibitor beyond first progression, achieving a median real-world progression-free survival (rwPFS) of 10.5 months and a median real-world overall survival (rwOS) of 71.3 months. The study also suggested that adding local treatment—particularly radiotherapy—was associated with improved outcomes.
