We used X-tile analysis software to obtain the best cut-off value of CAR (0.33), compared the clinical characteristics and survival of patients in the high CAR group and the low CAR group, and compared the survival status with the IPI scoring system. <strong>Results:</strong> 1) There were significant differences in staging, grouping, IPI scores, extranodal involvement, LDH levels, <em>β</em>2-microglobulin, CA125, and Hb levels between the high CAR group and the low CAR group (all <em>P</em> < 0.05). 2) According to the survival curve, the OS of the high CAR group was significantly shorter than that of the low CAR group (<em>P</em> < 0.01), and the one-year, three-year and five-year survival conditions of high CAR group were all shorter than those of low CAR group. 3) COX analysis showed that high CAR is an independent poor prognostic factor for DLBCL patients. 4) A comparative analysis of OS, three-year and five-year survival showed that the combination of CAR and IPI was significantly better than the IPI system, and there was no significant difference in the evaluation value of the prognosis between CAR alone and IPI alone. <strong>Conclusion:</strong> High CAR value, like the IPI scoring system, is an independent poor prognostic factor of DLBCL, can be used as a reliable indicator of prognosis. And CAR can also be combined with IPI to evaluate the prognosis of DLBCL, of which the effect is better than that of IPI alone.展开更多
