We hypothesized that polymorphism MTHFR C677T and A1298C should be associated with HD-MTX-related toxicities in children with NHL. Therefore, we aimed to retrospectively explore their relationships in this analysis.
Name: High-dose MTX based chemotherapy
Description: We recorded the toxicities that occurred to the patients after the MTX infusion, including hematological suppression, hepatotoxicity, nephrotoxicity, oral mucositis, vomiting and diarrhea.
Measure: Observations of HD-MTX-related toxicities Time: 3 weeksCohort
There are 3 SNPs

We recorded the toxicities that occurred to the patients after the MTX infusion, including hematological suppression, hepatotoxicity, nephrotoxicity, oral mucositis, vomiting and diarrhea.. Inclusion Criteria: patients who were: - Aged ≤ 18 years old; - Diagnosed as the four main types of NHL, including lymphoblastic lymphoma (LBL), Burkitt's lymphoma (BL), anaplastic large cell lymphoma (ALCL), diffuse large B-cell lymphoma (DLBCL); - Treated with HD-MTX therapy at the dose of 5g/m2; - Genotyped by PCR following Sanger with respect to MTHFR C677T and A1298C - With complete medical records. --- C677T --- --- A1298C ---
Exclusion Criteria: patients who were: - Aged >18 years old; - Diagnosed as cancer types other than the four main types of NHL; - Treated with no HD-MTX therapy or at the dose other than 5g/m2; - Not genotyped by PCR following Sanger with respect to MTHFR C677T and A1298C - With incomplete medical records . --- C677T --- --- A1298C ---

The most two extensively studied SNPs of MTHFR in relation to the toxicities of MTX are the C677T variant (Ala222Val, rs1801133) and A1298C variant (Glu 429Ala, rs1801131), both dampening the enzyme activity by 40-70%. --- C677T --- --- Ala222Val --- --- A1298C ---
Therefore, the aim of this retrospective study was to evaluate the influence of C677T and A1298C polymorphisms on HD-MTX-related toxicities in children with NHL treated according to BFM-modified protocols. --- C677T --- --- A1298C ---
