Dewi Vernerey: The Results of the ASTER 70s Trial

Dewi Vernerey, Head of the methodology and quality of life unit in oncology at CHU de Besançon, shared on LinkedIn:

“I am delighted to announce that the results of the ASTER 70s trial have just been published in the prestigious journal, The Lancet!

ASTER 70s is the first phase 3 superiority trial investigating the benefit of chemotherapy versus no chemotherapy in the adjuvant setting specifically in women aged 70 years or older with oestrogen receptor-positive breast cancer and at high risk according to genomic grade index (GGI)

The addition of adjuvant chemotherapy to hormonotherapy conferred no statistically significant survival benefit and was associated with more adverse events and worse Health-related Quality of Life.

The ASTER 70s trial provides important information to improve shared decision making between doctor and patient when discussing adjuvant breast cancer treatment.

Despite a large clinical and geriatric assessment deployed in the trial, no subgroup has been identified to more precisely define patients who really benefit from chemotherapy addition to hormonotherapy.

A huge translational research program on tumor and blood samples is now ongoing: ASTER-T (PRTK-23) and ASTER predict (FONDATION ARC-24)

My sincere thanks to Prof. Etienne Brain from Institut Curie for the constant trust in the UMQVC and for the consideration of the role, work and essential commitment of the methodologist and statistician in clinical and translational research.

Special thoughts to the great working group composed of Telma ROQUE and Jerome Lemonnier from Unicancer and my colleague Julie Henriques from UMQVC.”
