ORCHIDEA: A Retrospective Study of Patient Demographics, Clinical Characteristics, and Adjuvant Therapy Patterns in Stage II–III HR+/HER2– Breast Cancer Within Routine Clinical Practice

Abstract

Patients with stage II–III hormone receptor-positive, HER2-negative breast cancer (HR+/HER2- BC) maintain a persistent risk of recurrence for many years despite comprehensive treatment. Identifying risk factors enables adjuvant hormone therapy intensification and recurrence prevention.
