Abstract

Adjuvant CDK4/6 inhibitors (abemaciclib and ribociclib) associated with endocrine therapy reduced the risk of relapse for HR+/HER2- early breast cancer (eBC) patients in the monarchE and NATALEE trials. In this population-based study, we assess the real-life proportion, and long-term prognosis of patients treated for HR+/HER2- eBC between 2005 and 2015, and eligible for adjuvant CDK4/6 inhibitors according to these trial inclusion criteria. Among 3,103 patients, N = 440 (14.2%) would have been eligible for adjuvant abemaciclib, and N = 1068 (34.4%) for ribociclib. Node-negative patients who would have been eligible for adjuvant ribociclib represent 10.9% of the eligible population. 21.7% of patients now eligible for adjuvant abemaciclib, and 32.1% for ribociclib did not receive (neo)adjuvant chemotherapy. After a median follow-up of 144.7 months, 10-year overall survival confirms the prognostic relevance of the inclusion criteria used in pivotal trials. This study provides real-life insights into the prevalence, clinicopathological characteristics and long-term prognosis of HR+/HER2- eBC patients now eligible for adjuvant CDK4/6 inhibitors.

期刊介绍： npj Breast Cancer publishes original research articles, reviews, brief correspondence, meeting reports, editorial summaries and hypothesis generating observations which could be unexplained or preliminary findings from experiments, novel ideas, or the framing of new questions that need to be solved. Featured topics of the journal include imaging, immunotherapy, molecular classification of disease, mechanism-based therapies largely targeting signal transduction pathways, carcinogenesis including hereditary susceptibility and molecular epidemiology, survivorship issues including long-term toxicities of treatment and secondary neoplasm occurrence, the biophysics of cancer, mechanisms of metastasis and their perturbation, and studies of the tumor microenvironment.
