Research Abstract

We investigated the way to improve sensitivity and reproducibility of CTC assay. Recovery rate of basal type phenotype was improved with additional staining with anti-EpCAM antibody and anti-P-cadherin antibody. CTC count and viability in patients with breast cancer who received neoajuvant chemotherapy was also evaluated. Evaluation of CTC viability using M30 may help to evaluate response of neoadjuvant chemotherapy.
