Comparison of tumor response between SCCHN with and without lymph node metastases.

	Without N (n = 91)	With N (n = 46)
ORR, % (95% CI)	75.8 (65.7–84.2)	65.2 (49.8–78.6)
Best overall response
CR, n (%)	46 (50.6)	17 (36.7)
PR, n (%)	23 (25.3)	13 (28.3)
SD, n (%)	17 (18.7)	14 (30.4)
PD, n (%)	5 (5.2)	1 (2.2)
NE, n (%)	0	1 (2.2)

Tumor response in patients receiving post-treatment intervention was also included in the analysis. Abbreviations: SCCHN, squamous cell carcinoma of the head and neck; ORR, overall response rate; CI, confidence interval; CR, complete response; partial response; SD, stable disease; PD, progressive disease; NE, not evaluated.
