As we move forward with integration of molecular classification into clinical care the assessment of additional clinicopathological and molecular features in the context of molecular subtype will enable us to further refine prognosis. In addition, molecular classification can enable stratification of clinical cohorts that have been often thought of as homogeneous but are clearly more diverse than recognized. These last few years have produced an abundance of literature supporting not only the value of consistent categorization and prognostic value but also predictive implications enabling action/change in practice. Molecular classification-driven care in endometrial cancer will reduce variation in practice with improved knowledge translation critical to implementation and uptake.
