Meta-Analysis of CAR T-Cell Therapy Outcomes in Central Nervous System Lymphoma

This meta-analysis synthesizes data from 38 studies on CAR T-cell therapy for central nervous system lymphoma. It reports pooled efficacy outcomes, including an overall response rate of 0.75, and safety profiles for Cytokine Release Syndrome and Immune Effector Cell-Associated Neurotoxicity Syndrome. The analysis was conducted by Ahmad E. Shawabkeh and published in 2026.

Use Cases

• Analyze the relationship between CNS lymphoma subtype (PCNSL vs SCNSL) and pooled response rates (ORR, CR, PR) from 38 studies.
• Model the incidence and severity of Cytokine Release Syndrome (CRS) and Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) using reported proportions and confidence intervals.
• Investigate heterogeneity (I²) metrics across studies for outcomes like ICANS, which showed substantial heterogeneity of 84.2%.
• Assess publication bias for efficacy endpoints using the reported Egger's regression p-value of 0.39 for ORR.

Strengths

• Data is synthesized from 38 distinct studies, providing a broad evidence base.
• Reports specific, pooled statistical measures with confidence intervals, such as an ORR of 0.75 [0.70–0.79].
• Includes detailed subgroup and meta-regression analyses evaluating moderators like lymphoma subtype and publication year.

Limitations

• The underlying data is aggregated from published studies; individual patient-level data is not available.
• Substantial statistical heterogeneity was noted for some outcomes, such as ICANS (I² = 84.2%), indicating variability between studies.
• The dataset is a 61.2 KB document containing analysis results, not a primary tabular dataset suitable for direct machine learning.
