BEAM, carmustine, etoposide, cytarabine and melphalan; Bu/Cy, busulfan/cyclophosphamide; CBV, cy, carmustine, etoposide; CT, computed tomography; Flu/Cy, fludarabine, cyclophosphamide; KPS, Karnofsky performance score; LDH, lactate dehydrogenase.
P values were calculated ignoring the missing values.
This includes 11 patients with primary mediastinal large B-cell lymphomas in the auto-HCT group and 4 in the CAR-T therapy group.
Hypothesis testing Kruskal-Wallis test.
Hypothesis testing Pearson χ2 test.
Patient race – other: auto-HCT: 1 native Hawaiian or other Pacific islander, 5 American Indian or Alaska Native, 5 more than 1 race. CAR-T: 1 more than 1 race.
