99 Our experience of borderline ovarian tumors in adolescents

Introduction/Background Objectives: ovarian tumor are rare in children and adolescents, the incidence increases with age of patients1,2,3. Commonly described as a low malignant potential tumors, present papillary projections and increased cell proliferation rate, but absent stromal invasion2,3. We investigate the clinical features, treatment and follow-up of borderline ovarian tumors. Methodology Materials and methods: We present 32 cases of ovarian borderline ovarian tumor on a girl the median age was 13 years (range from 9 to 16 years old), who were operated in child hospital 'Arabkir'MC from 2017–2021. Patients complaints of strong abdominal pain during the last week and a feeling of heaviness, increasing the size of abdomen over the past 3–4 months. Ultrasound scan revealed the formation of large sizes tumor emanating from the ovary, filling the entire small pelvis with homogenous fluids in epithelial tumor, content mostly unilocular or binocular. In 15 cases, the formations reached 27–35cm in size, 17 cases -10–12cm. 12/37,5% cases at the time of admission has complete or partial torsion of adnexa or ovary. The doppler blood flow signal rate in ultrasonography was significantly different among tumor with torsion and without. The CA125 was in permissible limits of normal< 35U/mL in 62,5% cases and elevated till 49U/mL in 37,5% cases. Results Results: 15/47% patients underwent laparotomic and 17/53% laparoscopic cystectomy or adnexectomy respectively. Mass diameters were significantly higher in the laparotomy group. There were no significant differences in intraoperative blood loss or postoperative recurrence rates between the two groups. All patients were followed 48 months. Conclusion Conclusion: No recurrence was detected during following up period. According to data the incidence of recurrent borderline ovarian tumor in child and adolescent is unknown3. Further observation and routine sonographic control are a method of timely diagnosis of recurrent ovarian tumor formations to maintain reproductive ability. Disclosures None.
