Table 2. Comparison of two groups after neoadjuvant therapy.

Group	pCR (%)	PR (%)	SD (%)	PD (%)	ORR (%)	DCR (%)
Combined group	7 (30.4)	13 (56.5)	2 (8.7)	1 (4.3)	86.9	95.7
Chemotherapy group	3 (9.7)	14 (45.1)	10 (32.2)	4 (12.9)	54.9	87.1
P value	0.048	0.284	0.039	0.380	0.017	0.380

The classified variables were expressed by cases (%), and the chi-square test or Fisher exact probability method was used. pCR, pathological complete response; PR, partial response; SD, stable disease; PD, progressive disease; ORR, objective response rate; DCR, disease control rate.
