RESUMO
STUDY OBJECTIVE: To examine the recurrence rates of pediatric benign ovarian neoplasms METHODS: A retrospective review of females up to 21 years of age who underwent surgery for a benign ovarian neoplasm at 8 pediatric hospitals from January 2010 through December 2016 was conducted. Data include primary operation details, follow-up imaging, and reoperation details. RESULTS: Four hundred and twenty-six females were included in our cohort, with a median age of 15 years at the time of the primary operation. Of the patients, 69% had a mature teratoma, 18% had a serous cystadenoma, and 8% had a mucinous cystadenoma. Two-thirds of patients underwent ovarian-sparing surgery. There were 11 pathologically confirmed recurrences (2.6%) at a median follow-up of 12.8 months. The pathologically confirmed recurrence was 10.5 per 100 person-months at 12 months (SE = 5.7) for mucinous cystadenomas and 0.4 months (SE = 0.4) for mature teratomas (P = .001). For half of the patients, the pathologically confirmed recurrences occurred by 12.8 months, and for 75%, they occurred by 23.3 months. There were no differences in reoperation or recurrence on the basis of initial procedure (ovary-sparing surgery vs oophorectomy). CONCLUSION: We measured the pathologically confirmed recurrence rate for pediatric benign ovarian neoplasms in a large cohort. Oophorectomy was not protective against recurrence. Mucinous cystadenomas were at a greater risk of pathologically confirmed recurrence.

STUDY OBJECTIVE: To evaluate failure of initial operative therapy (incomplete tumor removal) of ovarian-sparing surgery for pediatric benign ovarian neoplasms. METHODS: A retrospective review of patients up to 21 years of age who underwent ovarian-sparing surgery for a benign ovarian neoplasm from 2010 to 2016 at 8 pediatric hospitals was conducted. Failure of initial operative therapy is defined as a radiologically suspected or pathologically confirmed ipsilateral lesion with the same pathology as the primary neoplasm within 12 weeks of the initial operation. RESULTS: Forty patients received imaging within 12 weeks of their primary operation. Sixteen (40%) patients had a radiologically identified ovarian abnormality ipsilateral to the primary lesion, and 5 patients were suspected to have the same lesion as their primary neoplasm. Three of the 5 patients (7.5%) underwent reoperation with pathologic confirmation of the same lesion, resulting in a pathologically confirmed failure of therapy rate of 7.5%. The other 2 patients had serial imaging that subsequently demonstrated no recurrence with lesion resolution. Age, race/ethnicity, laparoscopy vs laparotomy, presence of torsion, pathology, size of lesion, and surgeon specialty were not associated with failure of therapy. CONCLUSION: In most patients who received imaging within 12 weeks of the primary operation for resection of a benign ovarian neoplasm, ovarian-sparing surgery was successful in complete tumor removal, with a low failure of therapy rate. Selected patients with suspected failure of therapy on initial imaging could be serially monitored to determine the need for repeat surgical intervention.

BACKGROUND: With increased surgeon comfort using laparoscopy, we hypothesized resection of pediatric ovarian dermoids using laparoscopy would yield a shorter length of stay and no increase in morbidity or recurrence compared to laparotomy. METHODS: A retrospective review was performed amongst eleven pediatric hospitals. Patients aged 2 to 21 who underwent resection of an ovarian dermoid from 2010 to 2020 were included. Patient characteristics, operative details, and outcomes by approach were evaluated using Chi-squared and Wilcoxon-Mann tests. RESULTS: 466 patients were included, with a median age of 14.4 and median follow-up of 4.0 months. 279 patients underwent laparoscopy (60%), 139 laparotomy (30%), and 48 laparoscopy converted to laparotomy (10%). There were no differences in rates of tumor spillage by approach (p = 0.15). 65% underwent ovarian-sparing surgery and 35% underwent oophorectomy. Length of stay was significantly shorter amongst patients who underwent laparoscopy (1 day versus 2 days for laparotomy and converted, p<0.0001). There were no differences in rates of suspected recurrence or reoperation (p = 0.19 and p = 0.57, respectively). CONCLUSION: Patients who underwent laparoscopy experienced no differences in the rates of tumor spillage, recurrence, or reoperation and had a shorter length of stay compared to laparotomy. Laparoscopy is an acceptable approach for resection of pediatric ovarian dermoids.

STUDY OBJECTIVE: To assess the preoperative imaging impression and surgeon diagnostic accuracy for pediatric ovarian mature cystic teratomas (MCTs) DESIGN: Retrospective review SETTING: Eleven pediatric hospitals PARTICIPANTS: Patients ages 2 to 21 who underwent surgical management of an ovarian neoplasm or adnexal torsion with an associated ovarian lesion INTERVENTION: None MAIN OUTCOME MEASURES: Preoperative imaging impression, surgeon diagnosis, tumor markers, and pathology RESULTS: Our cohort included 946 females. Final pathology identified 422 (45%) MCTs, 405 (43%) other benign pathologies, and 119 (12%) malignancies. Preoperative imaging impression for MCTs had a 70% sensitivity, 92% specificity, 88% positive predictive value (PPV), and 79% negative predictive value (NPV). For the preoperative surgeon diagnosis, sensitivity was 59%, specificity 96%, PPV 92%, and NPV 74%. Some measures of diagnostic accuracy were affected by the presence of torsion, size of the lesion on imaging, imaging modality, and surgeon specialty. Of the 352 masses preoperatively thought to be MCTs, 14 were malignancies (4%). Eleven patients with inaccurately diagnosed malignancies had tumor markers evaluated and 82% had at least 1 elevated tumor marker, compared with 49% of those with MCTs. CONCLUSIONS: Diagnostic accuracy for the preoperative imaging impression and surgeon diagnosis is lower than expected for pediatric ovarian MCTs. For all ovarian neoplasms, preoperative risk assessment including a panel of tumor markers and a multidisciplinary review is recommended. This process could minimize the risk of misdiagnosis and improve operative planning to maximize the use of ovarian-sparing surgery for benign lesions and allow for appropriate resection and staging for lesions suspected to be malignant.

STUDY OBJECTIVE: To assess postoperative management of pediatric patients with benign ovarian neoplasms, to develop recommendations for postoperative care. DESIGN: A retrospective cohort study. SETTING: Eight pediatric hospitals in the midwestern United States. PARTICIPANTS: Patients up to 21 years of age who underwent surgery for a benign ovarian neoplasm between January 2010 and December 2016 were included. INTERVENTIONS: No prospective interventions were evaluated. MAIN OUTCOME MEASURES: Main outcome measures included postoperative imaging findings, recurrence rates, reoperation rates, and the timing of the aforementioned results. RESULTS: A total of 427 patients met inclusion criteria. After the index surgery, 155 patients (36%) underwent a routine imaging study. Among those with routine imaging, abnormalities were noted in 48 patients (31%); 7 went on to have reoperation (5%), and no malignant pathologies or torsion were identified. Excluding the 7 patients who went on to have a reoperation as a result of routine imaging, 113 patients developed symptoms postoperatively and underwent imaging as a result (27%, 113/420). Abnormalities were noted in 44 (10%); 15 of these patients underwent reoperation (4%), among them 2 with malignancies and 3 with torsion. Of these 44 patients, 23 had initially undergone routine imaging and subsequently went on to have symptomatic imaging, with 17% (4/23) undergoing reoperation. CONCLUSIONS: Routine imaging did not identify malignancy; most lesions identified on routine imaging were incidental findings. Although the study was not powered to appreciate a statistically significant difference, patients with malignancy or torsion were identified in the symptomatic group. This suggests no benefit from routine imaging, and supports symptomatic imaging postoperatively to minimize costs and patient/family burden.
