Description

Peripheral blood samples from 36 patients with locally advanced breast cancer who had undergone neoadjuvant chemotherapy were collected for circulating tumor cell (CTC) and plasma microRNA (miR) analysis. Pretreatment CTC and ALDH1 positivity (P = .0245) correlated, with miR-146b-5p and miR-199a-5p accompanied by CTC positivity. CTC and miR profiling of serial samples during neoadjuvant chemotherapy appears to be a very useful in predicting cure and clinical course.
