DA-R-EPOCH May Mitigate the Adverse Prognostic Implication of the Diagnosis-to-Treatment Interval (DTI) in Large B-Cell Lymphomas.
Article in Clinical lymphoma, myeloma & leukemia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundShort diagnosis-to-treatment interval (DTI) is associated with high-risk disease and poor survival in diffuse large B-cell lymphoma (DLBCL). There is a paucity of literature on DTI and survival in DLBCL treated with first-line DA-R-EPOCH. We hypothesized that rapid initiation of DA-R-EPOCH in aggressive and high-risk DLBCL mitigates the adverse prognostic implication of short DTI. PATIENTS AND
methodsWe retrospectively examined the association of DTI, categorically (short DTI ≤ 14 and long > 14 days) and continuously, with clinical features and survival outcomes in DLBCL treated with first-line DA-R-EPOCH at our institution.
resultsA total 190 patients were analyzed, 21% with high-grade DLBCL subtypes, 56% IPI ≥ 3, and median DTI of 13 days. The short DTI cohort contained more patients with IPI ≥ 3, bulky disease, and elevated LDH. When analyzed categorically and continuously, DTI was not associated with significant differences in PFS or OS. There was significant multivariable interaction between bulky disease, DTI, and PFS (P = .033), with improved PFS in patients with bulky disease in the short DTI cohort.
conclusionWe found that negative prognostic implications of DTI are mitigated in DLBCL patients treated with first-line DA-R-EPOCH, suggesting that urgent initiation of DA-R-EPOCH in high-risk DLBCL, including bulky disease, may improve survival. Our study's shorter DTI compared with DTIs reported in prospective DLBCL trials highlights DTI as a marker of external validity in clinical trial results. Future trials should implement protocols encouraging shorter, realistic DTIs to avoid selection bias against high-risk patients who are unable to delay treatment.
