Efficacy and Safety of Lisocabtagene Maraleucel in Relapsed or Refractory Large B-Cell Lymphoma: A Product-Specific Systematic Review and Meta-Analysis of Clinical Trials and Real-World Studies.
Review in Hematology reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND/
objectivesLisocabtagene maraleucel (liso-cel) is a CD19-directed chimeric antigen receptor T-cell (CAR-T) therapy approved for relapsed or refractory large B-cell lymphoma (R/R LBCL). However, most published meta-analyses of CAR-T therapy in LBCL pool data across products, limiting product-specific interpretation.
methodsWe conducted a systematic review and meta-analysis of clinical trials and retrospective real-world studies evaluating liso-cel monotherapy in R/R LBCL. The primary endpoint was the overall response rate (ORR). Secondary endpoints included complete response (CR), incidence of grade ≥ 3 adverse events, including cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), overall mortality rate (OMR), disease progression-related mortality, and adverse event-related mortality. Pooled proportions were estimated using random-effects models.
resultsEleven studies including 1206 patients were analyzed, comprising five clinical trials and six real-world retrospective cohorts. The pooled ORR was 78%, and the pooled CR rate was 60%. The pooled OMR was 38%, with a disease progression-related mortality of 28% and an adverse event-related mortality of 4%. Severe (grade ≥ 3) CRS and ICANS occurred in 2% and 8%, respectively. Severe (grade ≥ 3) hematologic toxicities were frequent, particularly neutropenia, thrombocytopenia, and anemia.
conclusionsLiso-cel monotherapy demonstrated high pooled response rates and low pooled incidences of severe CRS and ICANS across clinical trials and real-world settings in R/R LBCL. Severe ICANS, although uncommon, remains clinically meaningful, and severe hematologic toxicities were frequent and warrant careful monitoring and supportive care. These findings provide product-specific benchmarks for liso-cel in R/R LBCL.
