We examined the associations between susceptibility to malignant lymphoma and these polymorphisms. DESIGN AND METHODS: A hospital-based prevalent case-control study was conducted in Aichi Cancer Center. One hundred and eight patients with histologically confirmed lymphoma and 494 control subjects without cancer were evaluated. RESULTS: In a risk estimation of each genotype, those who harbored at least one TS 2 repeat (2R) allele had a 1.6-fold increase in the risk of malignant lymphoma (OR=1.63; 95%CI, 1.05-2.53, p=0.030) when using those without the TS 2R allele as a reference. For the SHMT1 C1420T polymorphism, those harboring at least one T allele showed a 2.2-fold decrease in risk (OR =0.46; 95% CI, 0.23-0.93, p=0.031). Moreover, combined analysis of TS and SHMT1 polymorphisms revealed that the OR for lymphoma in patients with SHMT1 1420 CC and the TS 2R allele, which might be expected to provide the basis for the highest susceptibility, was 2.88 (95% CI, 1.26-6.58, p=0.013). INTERPRETATIONS AND CONCLUSIONS: This study suggests that genetic traits involving low penetrance polymorphisms in folate-metabolizing genes may modulate the risk of malignant lymphoma.}, number={2}, journal={Haematologica}, author={A Hishida and K Matsuo and N Hamajima and H Ito and M Ogura and Y Kagami and H Taji and Y Morishima and N Emi and K Tajima}, year={2003}, month={Feb.}, pages={159-166} }
