Genotyping of the ERCC-1 gene single nucleotide polymorphisms.

Genotype	N (%)
T19007C
TT (reference genotype)	24 (53)
CT (heterozygous variant)	19 (42)
CC (homozygous variant)	2 (5)
CT + CC (polymorphic genotype)	21 (47)
C8092A
CC (reference genotype)	29 (64)
AC (heterozygous variant)	12 (27)
AA (homozygous variant)	4 (9)
AC + AA (polymorphic genotype)	16 (36)
Both T19007C + C8092A PG*	11 (24)
Only T19007C PG	10 (22)
Only C8092A PG	5 (11)
No T19007C PG nor C8092A PG	19 (42)

^*Odds Ratio = 4.18 (95% CI, 1.13–15.42); P = 0.027.
