Surveillance of Circulating Tumor Cell Phenotype in Early Stage Breast Cancer Patients With Neoadjuvant Chemotherapy or Adjuvant Chemotherapy
The phenotype of circulating tumor cells (CTCs) is supposed to be significant indicator that is correlated the prognosis of breast cancer patients who have completed neoadjuvant chemotherapy, primary tumor surgery with/without adjuvant chemotherapy. The aim of this observational study is to assess the efficacy of CTCs surveillance in predicting the prognosis of breast cancer patients.
