Table 1.

The number of cells corresponding to distinct patients (KTN102, KTN126, KTN129, KTN132, KTN302, and KTN615) and NAC resistance/treatment group

Cell group	KTN102	KTN126	KTN129	KTN132	KTN302	KTN615
SB	59	0	0	216	0	266
SM	0	0	0	443	0	96
SA	97	0	0	0	0	0
RB	0	122	406	0	0	0
RM	0	0	0	0	313	0
RA	0	455	376	0	0	0

∗S: chemo-sensitive, R: chemoresistance, B: pre-NAC, M: mid-NAC, A: post-NAC.

Patients with persistent tumor clones after NAC were regarded as chemoresistant, and those without any clones were regarded as chemo-sensitive.¹⁴ See the abbreviations described in the table.
