1 A Retrospective Cohort Study: The Influence of MTHFR C677T and A1298C on the High-dose Methotrexate-Related Toxicities in Pediatric Patients With Non-Hodgkin Lymphoma

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.

NCT04283955 Pediatric NHL Drug: High-dose MTX based chemotherapy
MeSH: Lymphoma, Non-Hodgkin
HPO: Non-Hodgkin lymphoma

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 ---

Primary Outcomes

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 weeks
