Brief Summary

Breast cancer is one of the most common malignancies in women worldwide, and distant metastasis is the main cause of poor prognosis and death. This project aims to construct a precision prediction system based on multi-omics (digital pathology, immunohistochemistry, proteomics, gene sequencing) and artificial intelligence to predict distant and organ-specific metastasis (bone, lung, liver, brain) in breast cancer, analyze its mechanisms, and provide new solutions for precision medicine.

Sampling MethodNon-Probability Sample
Study Population

The study population comprises female patients diagnosed with breast cancer between 2000 and 2028, identified through participating hospital centers. This includes patients who have developed distant (organ-specific) metastasis (liver, lung, bone, or brain) and for whom primary and/or metastatic tissue samples are available.

You may qualify if:

  • Female patients pathologically diagnosed with breast cancer at our hospital or participating centers between January 1, 2000, and December 30, 2028.
  • Must meet one of the following: 1) Initially diagnosed with breast cancer at our hospital, has developed distant metastasis (liver, bone, lung, or brain), and has a biopsy or surgical specimen from the metastatic site stored at our hospital, with complete clinical information available. 2) Primary tumor specimen is not at our hospital, but a biopsy or surgical specimen from a distant metastatic site (liver, bone, lung, brain) is stored at our hospital.

You may not qualify if:

  • Concomitant metastatic malignancy from another primary cancer.
  • Incomplete clinical information.

RECRUITING

Biospecimen

Retention: SAMPLES WITH DNA

Based on the study protocol, the following specific types of biological samples will be collected, processed, and retained: * Primary tumor tissue * Metastatic tumor tissue, specifically from liver, lung, bone, and brain metastases * Paired samples of primary and metastatic tumors (with a goal of over 1,000 pairs) * Blood samples, which will be used for liquid biopsy * The informed consent form specifies the collection of 6-10ml of peripheral blood * Data from previously retained biological samples, such as plasma * Patient-derived breast organoids All collected samples will be stored at -80°C.

Data Sharing

IPD Sharing
Will not share

Sharing of IPD is not guaranteed and is strictly conditional. First, consent for the long-term storage and future research use of data is collected as a separate, optional item on the Informed Consent Form. Therefore, IPD cannot be shared from any participant who does not provide this specific optional consent. Second, the study involves highly sensitive multi-modal data, including digital pathology, proteomics, and genomic sequencing. This data is subject to strict privacy-preserving protocols (such as encryption and differential privacy) and oversight by the institutional data security committee to protect participant confidentiality and prevent re-identification.
