This study explored the competitive risk factors for cancer-specific death in older women with MpBC. Age, T stage, N stage, M stage, tumor size, surgery and radiotherapy were risk factors for cancer-specific death in older patients with MpBC. Based on these risk factors, we developed a competitive risk model to predict cancer-specific survival in older women with MpBC. The validation results of the model show that it is a very effective and reliable prediction tool. This predictive tool allows doctors and patients to make individualized clinical decisions.
