title: Analysis of the factors determining the type of surgical procedure in mature cystic teratomas.
abstract: It was aimed to evaluate which factors determine the surgical procedure selected by surgeons for cases with mature cystic teratoma (MCT).
  
  
  
  This study included 50 cases with histopathologically proven MCT between January 2011 and August 2016 at a tertiary reference hospital. Data related to demographic and clinical characteristics were retrieved from medical records. Multivariate logistic regression analysis was conducted to evaluate the independent factors determining the type of surgical procedure to be applied.
  
  
  
  A higher rate of patients with large cyst size and elevated CA 19-9 was determined in the postmenopausal patients compared to the premenopausal patients (p = 0.033, p = 0.035). Cystectomy and oopherectomy were applied to 72.55% and 27.5% of the cases respectively. No recurrence in the operated ovary was observed in the 1-year follow-up period in any of the cystectomy cases. The major and only independent variable for the preference of cystectomy over oopherectomy was found to be a younger age (≤ 40 years). There was no independent variable which predicted the selection of laparoscopy or laparotomy by surgeons.
  
  
  
  Cystectomy was seen to be preferred by surgeons in the majority of MCT patients aged ≤ 40 years regardless of the size of the cyst. This is plausible since these patients have greater concerns about future fertility compared to patients > 40 years old. No recurrence was detected in any of the cystectomy cases, which strengthens the feasibility of this procedure. No serious complications developed in laparoscopy which could render it a safe option for undertaking cystectomy/oopherectomy in MCT cases.
