Diagnostic Accuracy of Neutrophil/Lymphocyte Ratio, Red Cell Distribution Width and Platelet Distribution Width in Ovarian Torsion.

The main aim of this diagnostic case-control study of 136 patients with ovarian cysts (44 patients with ovarian torsion and 92 controls) was to determine the diagnostic value of haematologic inflammatory markers (neutrophil/lymphocyte ratio [NLR], red cell distribution width [RDW] and platelet distribution width [PDW]) for torsioned ovarian cysts. The presence of a torsioned ovarian cyst was identified by a 1.18-fold increase in the NLR (95%CI: 1.04-1.34, P = 0.009), a 1.22-fold increase in the RDW (95%CI: 1.04-1.43, P = 0.023) and a 1.93-fold increase in the PDW (95%CI: 1.19-3.14, P = 0.007). The NLR was the best predictor of a torsioned ovarian cyst (AUC: 0.74; 95% CI: 0.68-0.83). When an NLR cut-off value of 2.44 was used to determine ovarian torsion, the sensitivity, specificity, + LR and -LR were 70.5%, 70.7%, 2.40 and 0.42, respectively. In conclusion, the NLR may have diagnostic and prognostic value in determining torsioned ovarian cysts.
