Systematic Review and Network Meta-Analysis on Treating Hormone Receptor-Positive Metastatic Breast Cancer After CDK4/6 Inhibitors.

ABSTRACT:

Introduction

The optimal treatment of estrogen receptor-positive (ER +) metastatic breast cancer (MBC) after progression on cyclin-dependent 4/6 kinase inhibitors (CDK4/6i) is unknown.

Methods

We conducted a systematic review and network meta-analysis (NMA) of phase-II/-III randomized trials of ER + MBC post CDK4/6i + ET progression. We calculated the hazard ratio (HR) for progression-free survival (PFS) and overall survival (OS) using generic inverse variance and odds ratios (ORs) using the Mantel-Haenszel method for adverse events (AEs) with Review-Manager version-5.4. NMA was executed using WINBUGS (Microsoft Excel). Three molecular subgroups were analyzed: HER2-low, PI3K/AKT/mTOR, and the ESR1 mutation subgroup for selective estrogen receptor degrader (SERD).
