Interaction of ERCC1 and XRCC1 polymorphisms on survival of lung adenocarcinoma

	ERCC1 CC		ERCC1 CT/TT

XRCC1	MST	HR(95%CI)^A	MST	HR(95%CI)^A
GG	25.10	1.00	13.30	1.79(1.16-2.76)
GA/AA	12.47	1.64(1.11-2.44)	8.60	2.44(1.63-3.65)

Abbreviation: MST, median survival time; HR, hazard ratio; CI, confidence interval.

^AHR and 95%CI were calculated by Cox regression, with the ERCC1 wild genotype (CC) and XRCC1 wild genotype (GG) as the reference group;HRs were adjusted for age, stage, surgical operation and chemotherapy or radiotherapy.
