Key clinical point: Intercalated high-dose methotrexate (HD-MTX) was associated with increased toxicity and R-CHOP delays compared to end of treatment (EOT) delivery.
Major finding: Intercalating HD-MTX was the only factor independently associated with R-CHOP delay (HR 2.84 ; P = .001).
Study details: Retrospective analysis of DLCBL patients who received CNS prophylaxis with either i-HD-MTX (n=204) or EOT HD-MTX (n=130).
Disclosures: The abstract contained no conflict information.
