Table 3. Tumor responses to the FOLFOX regimen in patients of differing TSER genotypes.

Tumor response	TSER genotypes				P-valuea
	TSER*2/*2		TSER*2/*3
	(n = 6)		(n = 17)
	No	%	No	%
PD (n = 1)	0	0	1	5.9	0.02
PR (n = 9)	5	83.3	4	23.5
SD (n = 13)	1	16.7	12	70.6

PD, progressive disease; PR, partial response; SD, stable disease.

^aCalculated using Fisher’s exact test for the association between response (PR and SD) and TSER genotype.
