The Relationship between Intraoperative Rupture and Recurrence of Pediatric Ovarian Neoplasms: Preliminary Observations

Study ObjectiveWe investigated whether rupture increased the recurrence rate of pediatric ovarian neoplasms.Design20-year single-institution retrospective study.SettingTertiary, free-standing, university children's hospital.ParticipantsAll girls with ovarian neoplasms treated during between 1991 and 2011.Main Outcome MeasureTumor recurrence.ResultsFifty-nine tumors in 53 patients were managed, including 51/59 (86%) benign and 8/59 (14%) malignant. Laparotomy was employed in 44/59 (75%), laparoscopy in 8/59 (14%), and laparoscopy converted to laparotomy in 7/59 (12%). Total and partial oophorectomy (cystectomy) was used for 15/51 (29%) and 36/51 (71%) of benign tumors, respectively. All malignant tumors underwent total oophorectomy. Accidental rupture or intentional tumor puncture occurred in 26/56 cases (46%), 23/51 benign and 3/5 malignant. Rupture was associated with increasing cyst size on univariate and multivariate analyses (p = 0.002 and p = 0.004, respectively). There were 5 recurrences (9%) in 4 patients, including 4 benign (3 mature teratomas, 1 mucinous cystadenoma), and 1 malignant yolk sac tumor. Recurrence occurred in 2/30 (7%) without rupture and 3/26 (12%) with rupture, p = 0.66. Follow-up was available for 50/53 patients (94%), with a median of 23.8 months [range 0.2-189 months]. All recurrences were salvaged by surgery.ConclusionsIn this limited study, intra-operative rupture did not increase the recurrence rate or worsen the prognosis of pediatric ovarian neoplasms.
