Distribution of the Homologous Recombination-related (HRR) Genesmutationsand HRD in Breast Cancer
NCT05466786 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 255
Last updated 2025-10-03
Summary
This is a cross-sectional and an observational study, investigator-initiated study in HER2-low breast cancer patients. Approximately 255 subjects with HRD (homologous recombination deficiency) assessment will be enrolled in this study to examine the distribution and features of HRD/HRR (homologous recombination repair).
In this study, investigators plan to clarify the frequency of HRR/HRD in Chinese patients with HER2-low breast cancer.
In addition, it is planned to investigate any association between invasive disease-free survival (iDFS)/overall survival (OS) and HRD/HRR in HER2-low breast cancer patients.
