Consensus Guidelines for the Use of Cyclin-Dependent Kinase (CDK) 4/6 Inhibitors in the Management of Hormone Receptor Positive (HR+ve), Her2-ve Early Breast Cancer (EBC).

Abstract

It is still not possible for all patients with early breast cancer to be cured. Even when they respond well to initial therapy, there exists a substantial risk for recurrence, sometimes after several years. With the availability of cyclin-dependent kinase (CDK) 4/6 inhibitors the role of adjuvant therapy has improved, and so has the chance of cure. These consensus guidelines will ensure that the community oncologist will be able to take the right decision for their patient. The expert committee shares their real-world experience as well as the consensus voting results. Patients eligible for adjuvant therapy with CDK4/6 inhibitors should start that treatment at the earliest. Based on current published data, abemaciclib is the preferred CDK4/6 inhibitor that should be used in eligible patients (unless contraindicated). To ensure optimal dose intensity and adherence to treatment schedule, use of literature and patient information material can improves compliance. Treatment modification requires early reporting of adverse effects, a responsibility of the patient and caregiver (relatives).
