Distribution of CTCs percentages and CTC count in samples. (a) Distribution of circulating tumor cell-positive (CTC⁺) percentages in the three tubes collected at baseline and sequential blood samples. Dark gray: one tube is CTC⁺; medium gray: two tubes are CTC⁺; and light gray: three tubes are CTC⁺. (b) Stratification of CTC⁺ patients according to the CTC count in three groups at baseline and sequential blood samples. Dark gray: at least five CTCs; medium gray: two to four CTCs; and light gray: one CTC. AT, adjuvant therapy; NAT, neoadjuvant therapy.
