    Abstract:
    BACKGROUND/PURPOSE: Borderline ovarian tumors (BOTs) are uncommon in the pediatric population, and there have been limited studies that have included a small number of patients. In present study, we evaluated the clinical outcomes and the rates of recurrence of pediatric BOTs with larger sample size than those in previous studies. METHODS: A retrospective chart review was performed on 29 patients who were treated for histopathologically confirmed BOTs at our institution between January 1997 and December 2009. RESULTS: Twenty-nine patients (median age, 18 years) had a large-sized tumor (median, 19.8 cm). Abdominal pain was the most common symptom, seen in 82.8% of the patients, followed by abdominal distension. The permanent section histology revealed 25 mucinous (86.2%) and 4 serous type tumors (13.8%). There was considerable discordance between the permanent and frozen sections (rate of concordance, 55.1%). Disease stage was IA in 26 patients (89.7%) and stage IC in the other 3 patients (10.3%). All patients underwent fertility-preserving surgery. Overall, 4 patients (13.8%) experienced a clinically suspicious recurrence requiring surgery. In 2 cases, the suspected recurrences were found to be other benign ovarian tumors. In one case that was initially treated with left ovarian cystectomy for a mucinous BOT, subsequent left salpingo-oophorectomy confirmed recurrence of a mucinous BOT at 16-month follow-up. The last case was a newly developed primary ovarian mucinous carcinoma with no evidence of recurrence of a previous mucinous BOT at 26-month follow-up. CONCLUSIONS: This study shows that BOTs in pediatric populations can be successfully treated conservatively to preserve fertility with no apparent increased risk of morbidity or mortality compared with those of more radical surgical options.
