The CAR-HEMATOTOX score identifies patients at high risk for hematological toxicity, infectious complications, and poor treatment outcomes following brexucabtagene autoleucel for relapsed or refractory MCL.

CD19-directed CAR T-cell therapy with brexucabtagene autoleucel (brexu-cel) has substantially improved treatment outcomes for patients with relapsed/refractory mantle cell lymphoma (r/r MCL). Prolonged cytopenias and infections represent common and clinically relevant side effects. In this multicenter observational study, we describe cytopenias and infections in 103 r/r MCL patients receiving brexu-cel.

Histological diagnosis of acute graft-versus-host disease in different sites of the upper gastrointestinal tract with correlation to endoscopic findings.

Graft-versus-host disease (GvHD) involving the intestine is a threat to patients after allogeneic hematopoietic stem cell transplantation (alloHSCT). We evaluated biopsies from different sites of the upper gastrointestinal tract (GIT) of 97 patients after alloHSCT. Forty-six patients with clinical symptoms consistent with upper GI GvHD revealed histological features of GvHD in the esophagus, stomach, and/or duodenum.

Veno-occlusive disease of the lung after allogeneic haematopoietic stem-cell transplantation: An autopsy study.

Pulmonary veno-occlusive disease (pVOD) is a potentially life-threatening sequela of allogeneic haematopoietic stem-cell transplantation (alloHSCT). We conducted a morphometric evaluation of autopsy lung tissue to determine the incidence of pVOD and its association with donor type, conditioning regime, hepatic sinusoidal obstruction syndrome (hSOS), survival time, and graft versus host disease (GvHD). The degree of occlusion of pulmonary veins in 78 autopsy cases after alloHSCT and 12 control cases was assigned to one of the following categories: none, minor thickening of the intima (up to 33% narrowing), moderate pVOD wherein about half of the lumen (34-66%) is occluded, or advanced pVOD with near total or total (67-100%) obliteration of the lumen.

An investigation of the diagnostic, predictive, and prognostic impacts of three colonic biopsy grading systems for acute graft versus host disease.

Acute graft versus host disease (aGvHD) is an important, life-threatening complication after allogeneic hematopoietic stem cell transplantation (alloHSCT). To investigate the value of multiple simultaneous colon biopsies in improving diagnostic accuracy in patients with aGvHD, we retrospectively analyzed 157 patients after alloHSCT. The biopsies were evaluated individually using three established histological grading systems (Lerner, Sale, and Melson).
