Brief Summary
In nonmetastatic local advanced breast cancer patients, we are going to investigate whether circulating tumor DNA (ctDNA) detection can reflect the tumor response to neoadjuvant chemotherapy (NCT) and detect minimal residual disease after surgery.

Outcome Measures
Primary Outcomes (1)
The concentration of circulating DNA(ctDNA)
Take the blood each time before chemtherapy and measure the concentration of ctDNA
From date of neoadjuvant chemotherapy decided until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 100 months
Study Arms (1)
ctDNA level
ctDNA level during neoadjuant chemotherapy
Interventions
Draw blood from each enrolled patient every time before chemotherapy and measure the ctDNA level in plasma.

- Felt to be a possible candidate for neoadjuvant systemic therapy by their treating physician;
- ECOG score\<=2;
You may not qualify if:
