Aim: To examine whether polymorphisms in SULT1A1 and GSTP1 genes contribute to colorectal cancer development and whether they are associated with clinicopathological variables are not well identified. Methods: We examined the genotypes of 125 colorectal cancer patients and 666 healthy controls in a Swedish population by using PCR restriction fragment length polymorphism (RFLP). Results: SULT1A1 *2/*2 genotype (OR = 2.49, 95%CI = 1.48-4.19, P = 0.0002) and *2 allele (OR = 1.56, 95%CI = 1.16-2.10, P = 0.002) had an effect on colorectal cancer susceptibility, while GSTP1 genotype was without effect. However, GSTP1 G-type predicted a worse prognosis in the patients independently of gender, age, Dukes' stage, growth pattern, and differentiation (P = 0.03). Conclusion: Polymorphism in SULT1A1 may predispose to colorectal cancer and GSTP1 may be a biological indicator of prognosis in the patients. © 2005 The WJG Press and Elsevier Inc.
