Treatment Approach and Prognosis of Pediatric and Adolescent Nonepithelial Malignant Ovarian Tumors: A Retrospective Prognosis Analysis

Published:October 06, 2017DOI:


      Study Objective

      Nonepithelial malignant ovarian tumors are rare in the pediatric and adolescent population. The aim of this study was to observe the spectrum of pathology, presentation, outcome, and risk factors for survival of pediatric nonepithelial malignant ovarian tumors in a Chinese pediatric population.

      Design, Setting, Participants, Interventions, and Main Outcome Measures

      This was a retrospective study of 171 girls (median age at presentation of 14 years) diagnosed with primary malignant ovarian tumors between 1990 and 2014 at the Yat-Sen Memorial Hospital and Cancer Center of Sun Yat-sen University. Symptoms, pathological data, treatments, and outcomes were obtained retrospectively from the medical records.


      Most (85.96%, 147/171) tumors occurred in patients aged 10-18 years and most cases were International Federation of Gynecology and Obstetrics stage I (68.42%, 117/171). The predominant pathological type was germ cell tumors (87.13%, 149/171). All patients underwent surgery, and 87 (50.88%, 87/171) underwent conservative incomplete staging surgery (unilateral salpingo-oophorectomy or tumor excision). The 5-year progression-free survival (PFS) was 59.2%. The 5-year overall survival (OS) was 88.7%. Surgical hospital (hazard ratio, 0.388; 95% confidence interval, 0.213-0.706; P = .002) was independently associated with PFS. Recurrence state (hazard ratio, 163.26; 95% confidence interval, 1.321-20,181.875; P = .038) was independently associated with OS.


      Ovarian cancers in children and adolescents have features of good prognosis. Girls who received their first surgery in a tertiary hospital had better PFS. Patients who did not suffer recurrence had better OS.
