Prognostic role of interim PET-CT demonstrating partial metabolic response in diffuse large B-Cell lymphoma: a retrospective study.
Article in Annals of hematology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveInterim
methodsA retrospective analysis was performed from January 2018 to December 2023, focusing on patients with DLBCL who achieved PMR on interim PET-CT. Patient demographics, clinical characteristics, and semi-quantitative PET/CT metabolic parameters were extracted from the medical records. Multivariate analyses were conducted to identify the risk factors associated with failure to achieve complete metabolic remission (CMR) at the end of treatment (EOT). Receiver operating characteristic (ROC) curve analysis was employed to determine the optimal cut-off values for continuous predictive variables. Progression-free survival (PFS) and overall survival (OS) were estimated using Kaplan-Meier methods, and risk factors were evaluated using Cox regression models.
resultsIn a cohort consisting of 80 newly diagnosed DLBCL cases that exhibited PMR on interim PET scans, 50 cases ultimately achieved CMR, while the remaining 30 cases still had positive PET findings at EOT. Analysis revealed that the interim lesion-to-liver maximum standardized uptake value ratio (RLL) and bone marrow involvement were independent prognostic factors for positive PET-CT outcomes at EOT. Notably, an interim RLL threshold greater than 1.66 emerged as a reliable predictor with a sensitivity of 73.3% and a specificity of 72.0%. Additionally, the International Prognostic Index (IPI) and interim RLL were identified as independent prognostic indicators for both progression-free survival (PFS) and overall survival (OS).
conclusionOur study revealed that within the cohort of DLBCL patients exhibiting PMR on interim PET scans, an interim RLL greater than 1.66 and bone marrow involvement emerged as independent risk factors for positive PET results at the end of treatment. Additionally, the IPI and interim RLL were identified as independent prognostic markers for both progression-free survival and overall survival. The integration of clinical characteristics with semi-quantitative PET/CT parameters has the potential to enhance the prognostic role of interim PET/CT exhibiting PMR in DLBCL cases.
