Abstract
Background Cancer treatments of the last decades improve the survival rate of children and adolescents. However, chemo- and radiotherapy result in gonadal damage, leading to acute ovarian failure and sterility. The preservation of fertility is now an integral part of care of children requiring gonadotoxic treatments. Ovarian tissue cryopreservation (OTC) is an effective fertility preservation option that allows long-term storage of primordial follicles, subsequent transplantation, and restoration of endocrine function and fertility. The efficacy of this technique is well-demonstrated in adults but the data are scarce for pediatric patients. Currently, OTC represents the only possibility of preserving the potential fertility in prepubertal girls. Procedure This is a retrospective study of OTC practice of two French centers from January 2004 to May 2020. A total of 72 patients from pediatric units underwent cryopreservation of ovarian tissue before gonadotoxic therapy for malignant or non-malignant diseases. The ovarian cortex was cut into fragments and the number of follicles per square millimeter was evaluated histologically. The long-term follow-up includes survival rate and hormonal and fertility status. Results The mean age of patients at OTC was 9.3 years [0.2-17] and 29.2% were postpubertal; 51 had malignant diseases and 21 had non-malignant diseases. The most frequent diagnoses included acute leukemia, hemoglobinopathies, and neuroblastoma. Indication for OTC was stem cell transplantation for 81.9% (n = 59) of the patients. A third of each ovary was collected for 62.5% (n = 45) of the patients, a whole ovary for 33.3% (n = 24) of the patients, and a third of one ovary for 4.2% (n = 3) of the patients. An average of 17 fragments [5-35] per patient was cryoconserved. A correlation was found between the age of the patients and the number of fragments (p < 0.001). More fragments were obtained from partial bilateral harvesting than from whole ovary harvesting (p < 0.05). Histological analysis of ovarian tissue showed a median of 6.0 primordial follicles/mm2 [0.0-106.5] and no malignant cells were identified. A negative correlation was found between age and follicular density (p < 0.001). Median post-harvest follow-up was 92 months [1-188]. A total of 15 girls had died, 11 were still under treatment for their pathology, and 46 were in complete remission. Of all patients, 29 (40.2%) were subjected to a hormonal status evaluation and 26 were diagnosed with premature ovarian insufficiency (POI) (p < 0.001). One patient had undergone thawed ovarian tissue transplantation. Conclusion OTC should be proposed to all girls with high risk of developing POI following gonadotoxic therapies in order to give them the possibility of fertility and endocrine restoration.

ACTA ACUST UNITED AC 2021; 57:medicina57070680. [PMID: 34356961 PMCID: PMC8305641 DOI: 10.3390/medicina57070680] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 06/29/2021] [Accepted: 06/30/2021] [Indexed: 11/25/2022]
Abstract
Background and Objectives: To introduce a new technique for fast leakage-proof, intraumbilical, single-incision laparoscopic ovarian cystectomy for huge ovarian masses (>10 cm) Materials and Methods: Seven consecutive, reproductive-aged women, including three adolescents, with huge ovarian masses (mature cystic teratoma, n = 4; endometrioma, n = 2; and mucinous cystadenoma, n = 1) who underwent transumbilical single-incision ovarian cystectomy with the new “hybrid cystectomy and reimplantation” method were included. The procedure was: (1) trans-umbilical single-incision laparoscopy; (2) inspection of the pelvic cavity and placing the mass in a laparoscopic endo-bag for cystic content leakage prevention; (3) in-bag resection using cold scissors and minimal cauterization of the cystectomy site; (4) in-bag tissue extraction; (5) rapid extracorporeal cystectomy with traction without electrocautery; (6) re-insertion of the retrieved ovarian cortex intracorporeally through the single port, and (7) intracorporeal suture of the retrieved tissue to the in situ ovary. Results: The mean patient age was 24.71 ± 6.56 (range 17–37) years and the mean maximal diameter of the masses was 17.71 ± 2.86 (range 13–22) cm. There was no case of unintended intracorporeal cyst rupture and no need for copious irrigation for washing and suctioning the leaked mass content. The mean total operating time was 76.42 ± 6.39 (range 65–85) min, the total volume of saline used for irrigation was 814.28 ± 331.35 (range 500–1500) mL, and the estimated blood loss was 107.14 ± 47.72 (range 50–200) mL. There were no perioperative complications. All patients except the two endometriosis patients had regular, normal menstruation. Conclusions: Our preliminary findings were encouraging in terms of the safety and efficiency of the new method. Future trials need to elucidate the benefits of this method in terms of fertility preservation.
