Table 1 Demographic characteristics and NQO1 polymorphism among ESCC, GCA patients and controls

Groups	Control n (%)	ESCC n (%)	GCA n (%)
Sex
Male	109 (66.1)	124 (64.3)	92 (74.2)
Female	56 (33.9)	69 (35.7)	32 (25.8)
Mean age ± SD (yrs)	52 ± 7.16	59 ± 8.73	60 ± 8.24
Smoking status
Smoker	82 (49.7)	104 (53.9)	68 (59.8)
Non-smoker	83 (50.3)	89 (46.1)	46 (40.2)
Family history of UGIC
Positive	0	86 (44.6)	45 (36.3)
Negative	165 (100)	107 (55.4)	79 (63.7)
Genotype
C/C	52 (31.5)	51 (26.4)	40 (32.3)
C/T	86 (52.1)	92 (47.7)	55 (44.3)
T/T	27 (16.4)	50 (25.9)^a	29 (23.4)
Allele type
C	190 (57.6)	194 (50.3)	135 (54.4)
T	140 (42.4)	192 (49.7)^b	113 (45.6)

Note. ESCC: esophageal squamous cell carcinoma; GCA: gastric cardiac adenocarcinoma; NQO1: NAD(P)H: quinone oxidoreductase 1; UGIC: upper gastrointestinal cancer; a. The genotype frequency was significantly higher than that in healthy controls (χ² = 4.79, P = 0.028); b. The allele frequency was marginaly higher than that in healthy controls (χ² = 3.83, P = 0.05).

Table 2 Relative risk of the NQO1 C609T homogenous null for ESCC and GCA development

Groups	NQO1 genotype		aOR (95%CI)^d
Groups	C/C+C/T n (%)	T/T n (%)
Healthy controls	138 (83.6)	27 (16.4)	aOR (95%CI)^d
ESCC patient	143 (74.1)	50 (25.9)^a	1.78 (1.04-2.98)
Family history of UGIC
Positive	60 (69.8)	26 (30.2)^b	2.20 (1.18-3.98)
Negative	83 (77.6)	24 (22.4)	1.46 (0.79-2.63)
GCA patient	95 (76.6)	29 (23.4)	1.44 (0.86-2.30)
Family history of UGIC
Positive	30 (66.7)	15 (33.3)^c	2.55 (1.21-5.23)
Negative	65 (82.3)	14 (17.7)	1.10 (0.80-1.34)

Note. ESCC: esophageal squamous cell carcinoma; NQO1:NAD(P)H: quinone oxidoreductase 1; UGIC: upper gastrointestinal cancer; a, b, c. The genotype frequency was significantly higher than that in healthy controls (a. χ² = 4.79, P = 0.028; b. χ² = 6.53, P = 0.011; c. χ² = 6.36, P = 0.012); d. The age, sex and smoking status adjusted relative risk of the NQO1 C609T homogenous null genotype (T/T) against the combination of the heterozygote (C/T) and homozygous wild type (C/C).
