Researchers are evaluating the effectiveness of adjuvant ribociclib combined with hormone therapy (aromatase inhibitors with or without GnRH agonists) in patients with hormone receptor-positive, HER2-negative stage II-III breast cancer in Russia. The study includes both a prospective cohort receiving ribociclib plus hormone therapy and a retrospective cohort treated with hormone therapy alone. The goal is to assess treatment outcomes in different patient subgroups defined by tumor grade, lymph node involvement, and hormone therapy response. Participants in the prospective group receive ribociclib alongside aromatase inhibitors, with or without GnRH agonists, as part of their adjuvant therapy. The retrospective group includes patients treated with aromatase inhibitors alone during a specific period from July 2019 to July 2020. The study collects new data from the prospective group while also analyzing existing patient records from the retrospective group. Throughout the study, researchers monitor invasive breast cancer-free survival at 36, 48, and 60 months following treatment according to standardized criteria. Patient information is gathered from clinical records, including hormone therapy start dates and treatment responses. Safety and effectiveness are assessed by tracking outcomes over several years to better understand ribociclib's role in routine clinical practice for this type of breast cancer.
