Breast Cancer, a Survival Prediction Model
Brief summary
This project is a prospective, clinical cohort study initiated by researchers to study the high-risk factors affecting the overall survival of newly diagnosed ER + / HER2 - advanced breast cancer patients and to establish a prediction model of ER + / HER2 - advanced breast cancer patients affecting overall survival. This project is the first prospective prediction model for the survival of patients with advanced breast cancer, and it is also the first time to establish a survival prediction model for ER-positive / HER2 negative advanced breast cancer suitable for China's national conditions. According to the survival outcome predicted by the model, the newly diagnosed ER positive / HER2 negative advanced breast cancer was divided into three groups: low, medium, and high risk, which provided an important theoretical basis for further design of randomized controlled clinical research and guidance of individualized precise treatment scheme for different groups in the future.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| overall survival，OS | 5 years | The time from the beginning of treatment to the death of the patient |
| Tumor specific survival time, CSS | 5 years | The follow-up started from the first day of confirmed recurrence and metastasis. The end point of follow-up was the death caused by tumor related causes. |
Secondary
