Objective: The objective of this study was to evaluate clinical and laboratory characteristics of torsion on mature cystic teratomas (MCTs). In addition, we examined whether these factors could be helpful in diagnosing MCT torsion.
Methods: A retrospective medical record review was conducted for 384 patients who had undergone surgery and histologically verified ovarian MCTs at single university hospital between July 2006 and May 2017. Patients with or without torsion groups were compared with respect to clinical presentation, laboratory findings and surgical course. In addition, statistically significant indicators of the factors were additionally evaluated for diagnostic value.
Results: White blood cell (WBC) count, neutrophil count, neutrophil to lymphocyte (N/L) ratio, and tumor size were higher in the torsion group (n=24) than in the control group (n=360; P≤0.005 for all). The age was younger in the torsion group than in the control (P=0.009). In the area under the curve (AUC) of the 5 factors obtained by univariate and multivariate logistic regression, the age was 0.657, the WBC count was 0.838, the neutrophil count was 0.806, the N/L ratio was 0.725, and the cyst size was 0.705. Receiver operating characteristic analysis indicated that the AUC for the combined use of age, WBC count, neutrophil count, N/L ratio, and tumor size was 0.898 (95% confidence interval, 0.833?0.962; P<0.001).
Conclusion: The combined measurement of age, WBC count, neutrophil count, N/L ratio, and tumor size may be used as a potential diagnostic marker for the torsion on MCTs.
