Matthew Kurian: 2025 CDK4/6 Data Reassure and Guide Adjuvant Breast Cancer Care

Matthew Kurian, Assistant Professor of Medicine at the University of Kentucky College of Medicine and Physician at St. Elizabeth Healthcare, shared a post on LinkedIn:

“New Year reflections in breast oncology!

The 2025 CDK4/6 inhibitor data are reassuring us as oncologists that our adjuvant strategy is worth it — clinically and meaningfully for patients. Hope to give more updates regarding my impressions of the data as a community based breast focused medical oncologist.

Ribociclib (NATALEE)

At 5 years, iDFS 85.5% vs 81.0% (HR 0.716) — durable prevention of recurrence and metastatic disease.

Abemaciclib (monarchE)

Now showing overall survival benefit with a ~16% reduction in risk of death (HR 0.842).

Why this matters:

We ask patients to accept treatment duration, side effects, and financial toxicity in the adjuvant setting. These data reassure us that:

  • We are preventing metastatic recurrence
  • Patients are living longer
  • More patients are living without metastatic disease

Grateful to discuss the NATALEE 5-year data at SABCS2025 with OncUpdates and Oncology Brothers, and to see the CDK4/6 story continue to mature with outcomes that truly matter to patients. Check out my interview with Komal Jhaveri, MD FACP, FASCO below!”
