Breast Cancer Real-World Insights and Decision Guidance Evaluation in Hong Kong (BRIDGE-HK)

2026年11月2日 更新者:AstraZeneca

Breast Cancer Real-World Insights and Decision Guidance Evaluation (BRIDGE-HK) An Observational, Retrospective, Real-world Study on Breast Cancer Patients in Hong Kong Using the Hospital Authority CDARS Database

Breast cancer is the most common cancer affecting women in Hong Kong, but comprehensive real-world evidence on treatment and outcomes remains limited. This retrospective observational study will use Hong Kong Hospital Authority electronic health records, covering approximately 80% of healthcare utilisation, to evaluate around 45,000 adult women treated between 2018 and 2025. The study will describe patient characteristics, treatment patterns, treatment sequences, treatment duration, discontinuation, response, overall survival, and progression-free survival across HER2-positive, hormone receptor-positive/HER2-negative, and triple-negative subtypes. It will also assess neoadjuvant therapy, pathological complete response, and disease-free survival in eligible early-stage patients.

調査対象母集団

Female breast cancer patients are anticipated, determined by data availability in the Hong Kong HA database (2018-2025).

説明

Inclusion Criteria:

  1. Female sex
  2. Age ≥18 years at the time of breast cancer diagnosis (index date)
  3. Histologically confirmed diagnosis of breast cancer (invasive or in situ) recorded in the HA database in all available records
  4. Documentation of surgery, or at least one systemic therapy (chemotherapy, endocrine therapy, targeted therapy, or immunotherapy) administered after the breast cancer diagnosis, as evidenced by pharmacy dispensing records or treatment administration records in the HA database between January 1, 2018, and December 31, 2025
  5. Availability of at least 6 months of follow-up data in the HA database after the index date, unless death occurs within the 6-month period

Exclusion Criteria:

  1. Male sex
  2. History of any other primary malignancy diagnosed prior to the index date (other than basal cell carcinoma of the skin and squamous cell carcinoma of the skin) as identified through ICD-9-CM codes 140.x-172.x, 176.x-208.x (excluding 174.x) recorded in the HA database during the 120-month baseline lookback period
  3. Patients with documented participation in an interventional clinical trial during the study period, where such information is available in the HA database, to preserve the real-world representativeness of observed treatment patterns
