The derived neutrophil‐to‐lymphocyte ratio is an independent prognostic factor in patients with angioimmunoblastic T‐cell lymphoma

To determine whether inflammatory markers, derived neutrophil‐to‐lymphocyte ratio (dNLR), haemoglobin/platelet ratio (HPR) or platelet/lymphocyte ratio (PLR) are predictive for prognosis in angioimmunoblastic T‐cell lymphoma (AITL), we derived dNLR, HPR and PLR values for 110 AITL patients and appropriate cut‐off point values to define overall survival (OS) and progression‐free survival (PFS). dNLR ≥ 2·2, HPR ≥ 0·4 or PLR < 100 were significant factors for shorter OS and PFS. On univariate analysis, these three parameters were significantly associated with worse OS and PFS. On multivariate analysis, only dNLR remained a significant, independent prognostic factor for both OS and PFS.
