Breast Cancer
Conditions
Brief summary
This is a multicenter, prospective, e, real-world cohort survey initiated by researchers to focus on the patterns of breast cancer management and prognosis of breast cancer in China, and to establish the multicenter, prospective breast cancer data platform. A total of 18 sites in Guangdong and Henan have cooperated to build a cooperative network unit. The sites will conduct prospective and standardized records concerning the clinical pathological features, treatment and prognosis of the early breast cancer patients who are treated in their own site each year, registering in the REDCap system.This real-world cohort study aims to provide a representative and reliable survey data of epidemiological characteristics, clinical treatment and prognosis of patients with early breast cancer in China and explore the establishment of a national multi-center breast cancer data platform model.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Breast-conserving surgery rate, | baseline | the proportion between breast-conserving surgery and breast mastectomy surgery baseline |
| Breast-conserving surgery rate, sentinel lymph node biopsy rate | baseline | the proportion between sentinel lymph node biopsy and axillary lymph node dissection |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Epidemiological distribution of pathological stage of breast cancer | baseline | the American Joint Committee on Cancer(AJCC) cancer staging system is used to assign stage for breast cancer patients,including primary tumor stage, regional nodes stage and metastasis stage |
| Disease free survival (DFS) | 5year | Disease free survival (DFS), which defined as the time from the diagnosis of breast cancer to the confirmed time of metastatic disease, or death due to any other cause. |
| Overall survival (OS) | 5year | Overall survival (OS), which defined as the time from the beginning of diagnosis of breast cancer to the death with any causes. |
