What relative dose intensity is associated with inferior outcomes in R-CHOP?

RDI below 85–90% has been associated with inferior overall survival in DLBCL treated with curative intent R-CHOP. Dose reductions and delays accumulate across cycles; G-CSF prophylaxis helps maintain RDI by reducing febrile neutropenia-related delays.

When should R-CHOP be dose-reduced vs maintained in elderly patients?

Age alone should not trigger dose reduction. Frailty assessment using CIRS or CGA determines fitness. Fit elderly patients (ECOG 0–2, no organ impairment) benefit from full-dose R-CHOP. Mini-CHOP or R-CHP is used for frail patients unable to tolerate anthracyclines.

CHOP Regimen Cycle Intensity Assessment

Assess R-CHOP cycle intensity maintenance by calculating dose intensity ratios for each component and overall regimen relative dose intensity (RDI) versus planned doses across cycles.
