NCT03786575

Brief Summary

To determine the landscape of gene mutation before and after endocrine therapy, to search for molecular markers of endocrine therapy efficacy, and to explore the clinical value of using NGS detection of ctDNA to guide precise endocrine therapy in patients with advanced breast cancer. The primary endpoints were progression-free survival (PFS), and the secondary endpoints included overall survival time (OS), adverse events (AE), and severe adverse events (SAE).

Outcome Measures

Primary Outcomes (1)

  • Progression-free survival (PFS)

    From date of first use endocrine treatment until the date of first documented progression or date of death from any cause, whichever came first

    up to 36 months

Secondary Outcomes (2)

  • Overall survival (OS)

    up to 60 months

  • Adverse events (AEs)

    up to 36 months

Study Arms (1)

NGS detection group

EXPERIMENTAL

Before treatment, the patients in the study group underwent NGS detection of ctDNA and formulated endocrine treatment plan according to the test results. After 2 months of endocrine therapy, all patients underwent NGS detection of ctDNA, and the efficacy was evaluated according to RECIST v1.1 standard.

Diagnostic Test: Next Generation Sequencing (NGS) detection

Interventions

The NGS detection panel is designed by our team and covers genes that are clinically useful and have definite guiding significance for endocrine therapy
