Table 2. Clinical response assessment according to RRM1 and ERCC1 expression.

Clinical response	L-RRM1 N = 41 (%)	H-RRM1 N = 12 (%)	P-values	L-ERCC1 N = 27 (%)	H-ERCC1 N = 26 (%)	P-values
CR+PR	29 (70.7)	3 (25.0)	0.007	19 (70.4)	13 (50.0)	0.130
SD+PD	12 (29.3)	9 (75.0)		8 (29.6)	13 (50.0)

Abbreviations: L-RRM1, low expression of RRM1; H-RRM1, high expression of RRM1; L-ERCC1, low expression of ERCC1; H-ERCC1, high expression of ERCC1; CR, complete remission; PR, partial remission; SD, stable disease; PD, progressive disease.
