Abstract
The clinical significance of hemoglobin-to-red blood cell distribution width (Hb/RDW) for the diagnosis of nasopharyngeal cancer (NPC) has not been reported yet. This study aimed to evaluate the value of preoperative Hb/RDW, neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) for the diagnosis of NPC.A total of 180 NPC patients (NPC group) and 149 healthy subjects (control group) were recruited to assess the value of Hb/RDW, NLR, and PLR for the diagnosis of NPC.It was noted that NLR and PLR were significantly higher in the NPC group than those in the control group (P < .001); however, Hb/RDW was lower in the NPC group compared with that in the control group (P < .001). NLR was also remarkably different between patients of stage I+II and those of stage III+IV (P = .043), and that was different in patients with lymph node metastases or not (P = .030). Besides, PLR was significantly different in patients with serosal invasion or not (P = .031). In receiver operating characteristic curve, compared with Hb/RDW alone (sensitivity, 66.67%; specificity, 85.23%), the sensitivity (67.78%, 72.78%) and specificity (89.62%, 90.6%) of Hb/RDW with NLR and PLR were both increased. Furthermore, Hb/RDW combined with NLR area under the ROC (AUC), 0.824; 95% confidence interval (CI): 0.779–0.864, P = .0080) or PLR (AUC: 0.851, 95% CI: 0.808–0.888, P = .0002) had a greater AUC value for the diagnosis of NPC compared with Hb/RDW alone (AUC: 0.781, 95% CI: 0.732–0.824).Hb/RDW can be used as a valuable indicator for auxiliary diagnosis of NPC. Preoperative Hb/RDW combined with NLR or PLR is of great significance in the auxiliary diagnosis and pathological staging of NPC.
