T cell lymphoma and secondary primary malignancy risk after commercial CAR T cell therapy

Abstract

We report a T cell lymphoma (TCL) occurring 3 months after anti-CD19 chimeric antigen receptor (CAR) T cell immunotherapy for non-Hodgkin B cell lymphoma. The TCL was diagnosed from a thoracic lymph node upon surgery for lung cancer. The TCL exhibited CD8+ cytotoxic phenotype and a JAK3 variant, while the CAR transgene was very low. The T cell clone was identified at low levels in the blood before CAR T infusion and in lung cancer. To assess the overall risk of secondary primary malignancy after commercial CAR T (CD19, BCMA), we analyzed 449 patients treated at the University of Pennsylvania. At a median follow-up of 10.3 months, 16 patients (3.6%) had a secondary primary malignancy. The median onset time was 26.4 and 9.7 months for solid and hematological malignancies, respectively. The projected 5-year cumulative incidence is 15.2% for solid and 2.3% for hematological malignancies. Overall, one case of TCL was observed, suggesting a low risk of TCL after CAR T.

Extended data

Extended Data Fig. 1 Histopathological evaluation of the recurrent B cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classic Hodgkin lymphoma (‘grey zone’ lymphoma).

H&E staining and immunohistochemistry were performed for CD5, CD20, CD30, CD79a, and PAX5, highlighting B cell origin. Histopathologic evaluation reveals aggressive B-lineage neoplasm, with a large CD30+ B lineage neoplasm for which the combined features favor a B cell lymphoma, unclassifiable (BCL-U), with features intermediate between diffuse large B cell lymphoma and classic Hodgkin lymphoma. H&E shows architectural effacement by sheets of mitotically active large cells with oval nuclei, condensed chromatin, prominent nucleoli, and ample eosinophilic cytoplasm. Occasional multinucleate and bizarre forms are noted. Immunohistochemical stains show CD20 negativity consistent with clinical history of rituximab. B cell lineage confirmed by CD79a and Pax5. CD5 highlights scattered T cells. 10x magnification, expect inlet 40X. The analyses were conducted during the diagnostic assessment of the patients or as correlative exploratory analyses (qPCR) and as such were performed once. Abbreviations: H&E: hematoxylin and eosin.

Extended Data Fig. 2 Histopathological evaluation of the non-small cell lung cancer.

H&E staining; 2x and 10x magnification. Immunohistochemistry for p63 and CK5/6; 2x magnification. H&E sections show invasive poorly differentiated carcinoma with marked nuclear enlargement and atypia (10x image) infiltrating into the lung parenchyma and with large areas of necrosis. Immunohistochemical stains showed tumor cells staining strongly positive for CK5/6 and p63 and supported the diagnosis of invasive poorly differentiated squamous cell carcinoma. The analyses were conducted during the diagnostic assessment of the patients or as correlative exploratory analyses (qPCR) and as such were performed once. Abbreviations: H&E: hematoxylin and eosin staining. NSCLC: non-small cell lung cancer.

Extended Data Table 2 Statistical considerations: Univariate analysis was performed using the Kaplan Meier method and compared using the Log-rank test. Multivariate analysis was performed using the Cox regression method. All tests were two-sided, and significance was defined as p < 0.05
