However, there have been several recent reports of local CRS characterized by cervical swelling. This localized syndrome can cause life-threatening laryngeal edema and requires early diagnostic treatment. Here we report 3 cases of local CRS where bilateral salivary gland swelling emerged following anti-CD19 CAR-T cell therapy for relapsed or refractory diffuse large B-cell lymphoma. Following tocilizumab treatment for systemic CRS, all patients exhibited cervical swelling. Physical examinations revealed significant swelling of the bilateral submandibular glands, and computed tomography scans showed substantial enlargement of the bilateral parotid and submandibular glands. Immediate treatment with dexamethasone effectively managed the potentially life-threatening laryngeal or pharyngeal edema, thereby preventing severe airway obstruction. This study has demonstrated, for the first time to our knowledge, that salivary gland enlargement is a common finding in local CRS. This observation suggests that physicians should continue to closely monitor the risk of developing cervical edema leading to life-threatening airway obstruction after systemic CRS, even in patients treated with tocilizumab. If salivary gland swelling is observed, it would be better to consider prompt evaluation and dexamethasone administration.</p>","PeriodicalId":45936,"journal":{"name":"Journal of Clinical and Experimental Hematopathology","volume":"64 3","pages":"261-267"},"PeriodicalIF":0.9,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11528259/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142356096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

IHC was performed on 57 biopsy samples (55 brain biopsy samples and two vitreous cell blocks) from 54 patients with CNS-DLBCL, including three biopsy samples initially diagnosed as negative or indeterminate for CNS-DLBCL. Additionally, IMP3 IHC was performed on 68 DLBCLs other than CNS-DLBCL and 12 inflammatory brain diseases. Cytoplasmic IMP3 expression was noted in ≥50% of tumor cells in 100% (57/57) of CNS-DLBCLs and 88.2% (60/68) of non-CNS-DLBCLs. In contrast, no IMP3-positive CD20-positive B cells were observed in the inflammatory brain disease (P < 0.0001). In conclusion, IMP3 is highly expressed in CNS-DLBCL. However, it is also expressed in other types of DLBCLs, making it less specific.

Our previous reports revealed that DFL shares characteristics of both NFL and mucosa-associated lymphoid tissue (MALT) lymphoma in terms of clinical and biological aspects, suggesting its pathogenesis may involve antigenic stimulation. In contrast to NFL, the genomic methylation status of DFL is still challenging. Here, we determined the methylation profiles of DNAs from patients with DFL (n = 12), NFL (n = 10), duodenal reactive lymphoid hyperplasia (D-RLH) (n = 7), nodal reactive lymphoid hyperplasia (N-RLH) (n = 5), and duodenal samples from normal subjects (NDU) (n = 5) using methylation specific PCR of targets previously identified in MALT lymphoma (CDKN2B/P15, CDKN2A/P16, CDKN2C/P18, MGMT, hMLH-1, TP73, DAPK, HCAD). DAPK1 was frequently methylated in DFL (9/12; 75%), NFL (9/10; 90%), and D-RLH (5/7; 71%). CDKN2B/P15 sequences were methylated in six DFL samples and in only one NFL sample. Immunohistochemical analysis showed that p15 expression inversely correlated with methylation status. Genes encoding other cyclin-dependent kinase inhibitors (CDKN2A/P16, CDKN2C/P18) were not methylated in DFL samples. Methylation of the genes of interest was not detected in DNAs from D-RLH, except for DAPK1, and the difference in the extent of methylation between NDU and D-RLH was statistically significant (P = 0.013).
