Neuropsychiatric disorders in hospitalized patients undergoing chimeric antigen receptor T-cell therapy for aggressive lymphomas and acute lymphoblastic leukemia: A national study.
Bibliographic record
Abstract
12118 Background: Chimeric antigen receptor T cell therapy (CART) has shown efficacy in acute lymphoblastic leukemia (ALL), diffuse large B cell lymphoma (DLBCL), and primary mediastinal B cell lymphoma (PMBCL). While neurological toxicities of CART are known, neuropsychiatric disorders (NPD) in patients undergoing CART has not been well described. Our study assessed the prevalence of NPD in hospitalized patients (pts) undergoing CART, and explored association of NPD with clinical variables. Methods: Using the National Inpatient Sample database, we conducted a retrospective study of pts with ALL, DLBCL and PMLCL aged ≥ 18 years who underwent CART in 2018. Hospitalizations were selected using International Classification of Disease, Tenth Revision (ICD-10) codes. NPD of interest included anxiety, depression, adjustment disorder, insomnia, psychosis, dementia, bipolar disorder. Delirium was not included in the inventory of NPD since delirium is a neurotoxicity of CART, and inclusion of delirium as NPD would confound results. Patient, disease, and CART complications were extracted from hospitalization records. Regression analyses were used to assess association of NPD with clinical variables. Results: 945 CART procedures met the inclusion criteria (56 % males and 60% Caucasians). Majority of CART (88%) were performed for DLBCL and PMBCL. NPD was diagnosed in 31 % of pts. Anxiety was the most common NPD, followed by insomnia and depression. ALL pts were more likely to have NPD compared to pts with lymphoma (52% versus 28%, p<0.05). More females had NPD compared to males (40% versus 25%, p<0.05). Univariable analysis showed association of NPD with female gender [Odds ratio (OR)=2.03, 95% CI = 1.05-3.93] and ALL (OR=2.76, 95% CI = 1.03-7.43). In a multivariable model, NPD was associated with ALL (OR =3.57, 95% CI= 1.01-12.55), while the association of NPD with female gender was less certain (OR =1.41, 95% CI=0.73 - 2.74). There was no association between NPD and mortality, neurotoxicity, systemic inflammatory response syndrome or hemophagocytic lymphohistiocytosis. Conclusions: One in every 3 pts who underwent in-hospital CART for ALL or aggressive B cell lymphoma in 2018 had comorbid NPD. Females and ALL pts were at higher risk for NPD. As CART pts transition into longer follow up and survivorship, ours and similar results should inform the planning and allocation of psychosocial services.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
