Summary

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.

Description

The aim of this observational study is to assess the efficacy of CTCs surveillance in predicting the treatment response of neoadjuvant chemotherapy, surgery and adjuvant chemotherapy. This study also aims to evaluate the efficacy of CTCs surveillance in predicting invasive-disease free survival (iDFS), overall survival (OS) and metastasis. Additionally, this study evaluate the expression of PDL1 and FOXC3 on CTCs.
