Implication

Retrospective analysis identifies SUVTLR ≥4.2 as a predictor of inferior event-free survival in DLBCL patients, suggesting improved prognostication beyond visual assessment.

Key Points

  • Interim SUVTLR ≥4.2 predicts inferior event-free survival at 9.87 months in R/R DLBCL patients.
  • The hazard ratio for inferior EFS associated with interim SUVTLR was 1.25, indicating substantial risk.
  • Semiquantitative metrics from interim FDG PET/CT scans were more informative than visual Deauville scores in assessing prognosis.
  • The study involved a cohort of 50 patients with R/R DLBCL who achieved partial response to salvage chemotherapy.
