Study Details
Study Description
Brief Summary
The study is a multi-center, non-interventional, prospective observational study which enrols 2500 breast cancer patients from China county area. The purpose of this study is to be aware of the real-world data of the current breast cancer diagnosis and treatment model in the county. It aims to understand the gap between the county and the SOC in the diagnosis and treatment.

Detailed Description
The study is a multi-center, non-interventional, prospective observational study which enrols 2500 breast cancer patients from China county area. The patients will be divided into four cohorts by HR/HER2 status and early/late stage without prespecified minimum or maximum limit of patient number for each cohort.
The potential study subjects will be identified by the investigators by face-to-face visit. During this process approximately 2500 subjects will be enrolled in 1 year. All subjects will be sign informed consent and recorded for demographic characteristics, medical history, treatment history, treatment hospital, pathologic diagnosis, receptor status, therapeutic regimen, etc at the beginning of enrollment. Normally, there will be 4 visits for EBC and 6 visits for ABC in hospitals during yearlong follow-up period. All visits are according to the standard frequency of clinical follow-up. If the patient does not come to the hospital for follow-up on a regular basis, we will follow-up by telephone inquiries, etc.The potential study subjects will be identified by the investigators by face-to-face visit.
