Brief Summary:
The use of circulating tumor DNA (ctDNA) as a noninvasive test for breast cancer monitoring throughout the course of the disease

Condition or disease
Metastatic Breast Cancer Mutation, Point

Detailed Description:
The concentrations of the cell free DNA (cfDNA) and somatic mutations in circulating tumor DNA (ctDNA) in serial samples correlate with the number of days of the progression-free period and with the overall survival.
