Lu X, Liu Y, Liu R, Liu J, Yan X, Qian L. Comparison of chemotherapy regimens plus rituximab in adult Burkitt lymphoma: A single-arm meta-analysis. Front Oncol 2022; 12:1063689. [PMID: 36620579 PMCID: PMC9816660 DOI: 10.3389/fonc.2022.1063689] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2022] [Accepted: 11/29/2022] [Indexed: 12/24/2022] Open
Abstract
Background and aim Given the paucity of evidence-based treatment recommendations, the most appropriate first-line regimen for adult Burkitt lymphoma is currently undefined. We aimed to identify the optimal treatment regimen containing rituximab for adult Burkitt lymphoma patients. Methods The PubMed, Embase, Web of Science, and Cochrane databases were searched in December 2021 (10). We included all studies for the treatment of Burkitt lymphoma including rituximab. We excluded studies of patients aged ≤14 years old and those with sample numbers ≤10 patients. Random-effects models were used to compare different chemotherapy regimens regarding estimated 2-year overall survival (OS) rate, 2-year progression-free survival (PFS) rate, and overall response rate (ORR). Results A total of 17 studies were included in this meta-analysis and divided into four groups: CODOX-M/IVAC, DA-EPOCH, GMALL-B-ALL/NHL2002, and Hyper-CVAD. DA-EPOCH was associated with a significantly higher 2-year OS rate [0.95, 95% confidence interval (CI) 0.86-1.00]. There was no significant difference in the 2-year PFS rates (0.81, 95% CI 0.76-0.85) and ORR (0.90, 95% CI 0.87-0.94) between these four treatment regimens. Conclusions The meta-analysis indicates that DA-EPOCH could be more effective in providing curative treatment for adult Burkitt lymphoma patients, especially without CNS and BM involvement considering OS time. Due to the types of studies and the limited number of included studies, bias should be acknowledged and a randomized controlled trial (RCT) needs to be performed to further identify the optimal treatment regimen for such patients.

Phosphorylation of PBK/TOPK Tyr74 by JAK2 promotes Burkitt lymphoma tumor growth. Cancer Lett 2022; 544:215812. [PMID: 35780928 DOI: 10.1016/j.canlet.2022.215812] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 06/08/2022] [Accepted: 06/27/2022] [Indexed: 11/02/2022]
Abstract
Burkitt lymphoma (BL), which is characterized by high invasiveness, is a subgroup of non-Hodgkin lymphoma. Although BL is regarded as a highly curable disease, especially for children, some patients unfortunately still do not respond adequately. The understanding of the etiology and molecular mechanisms of BL is still limited, and targeted therapies are still lacking. Here, we found that T-LAK cell-derived protein kinase (TOPK) and phosphorylated Janus kinase 2 (p-JAK2) are highly expressed in the tissues of BL patients. We report that TOPK directly binds to and is phosphorylated at Tyr74 by JAK2. Histone H3, one of the downstream targets of TOPK, is also phosphorylated in vivo and in vitro. Furthermore, we report that the phosphorylation of TOPK at Tyr74 by JAK2 plays a vital role in the proliferation of BL cells and promotes BL tumorigenesis in vivo. Phosphorylation of TOPK at Tyr74 by JAK2 enhances the stability of TOPK. Collectively, our results suggest that the JAK2/TOPK/histone H3 axis plays a key role in the proliferation of BL cells and BL tumorigenesis in vivo.
