modestly significantP = 0.02
Previously, the UGT1A7*3 allele exhibited modestly significant association with colorectal cancer (OR = 2.39; P = 0.02) [ 57 ], lung cancer [ 62 ], endometrial cancer [ 63 ] and pancreatic cancer (OR = 1.98; P = 0.003) [ 64 ] with a particularly strong association in smokers with pancreatic carcinoma who were younger than 55 years (OR = 4.7; P = 0.0009), suggesting the magnitude of the observed associations may be modified by environmental interactions.
