RESUMEN
OBJECTIVE: To investigate the effect of EBV-DNA copy number on the prognosis of patients with EBV positive lymphoma. METHODS: Clinical data of 109 patients diagnosed as EBV positive lymphoma in Tianjin Medical University Cancer Institute and Hospital from January 2010 to January 2020 were enrolled and analyzed retrospectively. Kaplan-Meier analysis was used for survival analysis, Log-rank was used to compare the clinical characteristics between the patients in different groups, and Cox regression was used for multivariate analysis. RESULTS: Among the 109 patients with EBV-positive lymphoma, the medium age were 56 (range 15 to 83) years old. 29 patients at Ann Arbor stage I-II while 80 patients at stage III-IV. The average value of EBV-DNA was 1 023 510 IU/ml, 7 patients were higher than the average value, while 102 patients were lower. KM survival analysis showed that OS and PFS in patients with EBV-DNA above average level were shorter than those in patients with EBV-DNA below average level (OS: P=0.048, PFS: P=0.001), EBV-DNA copy number was a factor affecting the prognosis of patients. In addition, LDH level showed positive correlation with EBV-DNA copy number (r=0.650), which was also one of the factors affecting OS (P=0.053). CONCLUSION: EBV-DNA copy number and LDH level can influence the prognosis of EBV positive lymphoma patients. Therefore, detection of EBV-DNA copy number in peripheral blood is important for evaluate the prognosis the patients.

Triple-hit lymphoma (THL), which is classified into high-grade B-cell lymphoma with rearrangements of MYC, BCL2 and BCL6, presents aggressive biological behaviour. High-dose chemotherapy followed by autologous hematopoietic stem cell transplantation (auto-HSCT) is considered to be one of the recommended treatment options. Here, we reported 3 THL patients received carmustine, etoposide, cytarabine and cyclophosphamide (BEAC) combined with chidamide and high-dose rituximab conditioning regimen and found that this conditioning showed good efficacy and tolerance without increase of adverse events.

Diffuse large B-cell lymphoma (DLBCL), the most common subtype of non-Hodgkin lymphoma, is highly heterogeneous and invasive. Although the majority of DLBCL patients show a good response to rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone treatment, approximately one-third of patients still have a poor prognosis. Many immune-targeted drugs, such as bispecific T-cell engagers and CAR T-cell therapy, have been proven effective for refractory and relapsed patients. This article reviews the progress of immune targeted therapy for DLBCL.
