This study aimed to analyze the efficacy and safety of chimeric antigen receptor T-cell (CAR-T) therapy for B-cell lymphoma using published literature data. Literature on CAR-T therapy for B-cell lymphoma was collected by searching common databases. The literature was screened, quality assessed, and data extracted according to the inclusion and exclusion criteria. We performed a quantitative meta-analysis of the efficacy and safety of combined literature data. If the data could not be combined, descriptive analysis was performed. The meta-analysis results indicated that compared with tisagenlecleucel (tisa-cel), axicabtagene ciloleucel (axi-cel) had higher objective response rate (ORR) and complete response rate, with odds ratio (OR) of 0.63 for both sides (95% confidence interval CI, 0.50-0.79) and statistically significant differences. Partial response rate was lower with axi-cel than with tisa-cel, with an OR of 1.02 for tisa-cel versus axi-cel (95% CI, 0.75-1.40) and no statistically significant difference. Compared with tisa-cel, axi-cel had longer progression-free survival and overall survival, with risk ratios of 0.70 (95% CI, 0.62-0.80) and 0.71 (95% CI, 0.61-0.84) for axi-cel and tisa-cel, respectively. Compared with tisa-cel, axi-cel had higher incidence rates of cytokine release syndrome (CRS) and immune effector cell-related neurotoxicity syndrome (ICANS), with ORs of 3.84 (95% CI, 2.10-7.03) and 4.4 (95% CI, 2.81-6.91), respectively. CAR T-cell therapy is an effective treatment option for relapsed/refractory B-cell lymphoma. Axi-cel has better ORR and survival advantages compared with tisa-cel; however, axi-cel has higher incidence rates of CRS and ICANS compared with tisa-cel.
