Study Details

Study Description

Brief Summary

This is a retrospective, observational, multi-center clinical study of circulating tumor DNA (ctDNA) application in late-stage breast cancers.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: ctDNA testing

Detailed Description

This study aims to evaluate the feasibility of plasma ctDNA mutation spectrum and clonal spectrum in late-stage metastatic breast cancer patients. Meanwhile, this study tries to establish a model of ctDNA subtyping system to evaluate the molecular load of tumor, to evaluate the curative effect comprehensively and to detect the disease progression in advance. In addition, the investigators plan to explore the clonal evolution of ctDNA in patients with progressive disease (PD), and to monitor the changes of tumor heterogeneity from the molecular level, so as to provide reference for the analysis of drug sensitivity.

Arms and Interventions

Arm Intervention/Treatment
Patients with late-stage metastatic breast cancers.

This cohort included patients with late-stage metastatic breast cancers and their disease progressed after at least two-line treatment.

Diagnostic Test: ctDNA testing
ctDNA testing was performed for late-stage metastatic breast cancer patients to trace their ctDNA abnormality.

Outcome Measures

Primary Outcome Measures

  1. ctDNA change index [From the date of recruitment until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12 months.]

    The dynamic change of the frequency spectrum of ctDNA mutation in plasma.
