General Information About Childhood Ovarian Cancer
Most ovarian masses in children are not malignant.
Most malignant ovarian tumors occur in girls aged 15 to 19 years.[5 ]

Childhood Epithelial Ovarian Neoplasia
Histology, Clinical Presentation, and Prognosis
Ovarian tumors derived from malignant epithelial elements include the following:
- Serous cystomas.
- Mucinous cystomas.
- Endometrial tumors.
- Clear cell tumors.
Within each classification, subtypes include benign tumors, tumors with low malignant potential or borderline tumors, and adenocarcinomas. Most ovarian tumors in the pediatric age range are benign and borderline,[1 ] with rare malignant lesions in adolescence.[2 ] Studies have reported the following:
- In the Italian prospective multicenter study of rare tumors (TREP project), of the 16 patients identified over 14 years, 8 patients had benign tumors (7 mucinous cystadenoma and 1 serous cystadenoma) and 8 patients had borderline tumors (2 serous and 6 mucinous).[3 ][Level of evidence: 3iA] No malignant tumors were identified. High levels of cancer antigen (CA)-125 were detected in 6 of 15 patients.
- In another series of 19 patients younger than 21 years with epithelial ovarian neoplasms, the average age at diagnosis was 19.7 years. Dysmenorrhea and abdominal pain were the most common presenting symptoms. Low malignant potential or well-differentiated tumors were diagnosed in 84% of patients, 79% of the patients had stage I disease with a 100% survival rate, and only those who had small cell anaplastic carcinomas died.[4 ][Level of evidence: 3iiiA]
Girls with ovarian carcinoma (epithelial ovarian neoplasia) fare better than do adults with similar histology, probably because girls usually present with low-stage disease.[4 ,5 ] The potential association with genetic predisposition (e.g., BRCA mutation) in pediatric patients has not yet been studied.
Treatment of Childhood Epithelial Ovarian Neoplasia
Treatment options for childhood epithelial ovarian neoplasia include the following:
- Surgery alone.
Treatment of epithelial ovarian neoplasia is based on stage and histology. Most pediatric and adolescent patients have stage I disease. In the TREP study,[3 ] of the eight patients with benign tumors, seven patients were stage I and one patient was stage III. Of the eight patients with borderline tumors, three patients were stage I and five patients were stage III (on the basis of washings and omental implants). All 16 patients were treated with surgery alone. Fifteen patients are alive without disease; the one death was not from ovarian cancer.
Treatment options for childhood malignant ovarian epithelial cancer include the following:
- Radiation therapy.
Treatment of malignant ovarian epithelial cancer is stage-related and follows adult protocols; it may include surgery, radiation therapy, and chemotherapy. (Refer to the PDQ summary on adult Ovarian Epithelial, Fallopian Tube, and Primary Peritoneal Cancer Treatment for more information.)

Childhood Sex Cord–Stromal Tumors
Histology and Molecular Features
Ovarian sex cord–stromal tumors are a heterogeneous group of rare tumors that derive from the gonadal non–germ cell component.[1 ] Histologic subtypes display some areas of gonadal differentiation and include juvenile (and, rarely, adult) granulosa cell tumors, Sertoli-Leydig cell tumors, and sclerosing stromal tumors. Other histological subtypes, such as steroid cell tumor, sex cord tumor with annular tubules, or thecoma, are exceedingly rare. Ovarian Sertoli-Leydig cell tumors in children and adolescents are commonly associated with the presence of germline DICER1 mutations and may be a manifestation of the familial pleuropulmonary blastoma syndrome.[2 ]
The clinical presentation and prognosis of sex cord–stromal tumors varies by histology. In all entities, metastatic spread occurs rarely and if present, is usually limited to the peritoneal cavity.[1 ] Distant metastases mostly occur in relapse situations.[3 ] Some tumors may be associated with hormone secretion; for example, estrogen in granulosa cell tumors or androgens in Sertoli-Leydig cell tumors.[4 ]
In the United States, these tumors may be registered in the Testicular and Ovarian Stromal Tumor registry.[5 ] In Europe, patients are prospectively registered in the national rare tumor groups.[5 ,6 ] The recommendations regarding diagnostic work-up, staging, and therapeutic strategy have been harmonized between these registries.[5 ]
In a report from the German Maligne Keimzelltumoren (MAKEI) study, 54 children and adolescents with prospectively registered sex cord–stromal tumors were analyzed. Forty-eight patients presented with stage I tumors, and six patients had peritoneal metastases. While overall prognosis was favorable, patients at risk could be identified by stage (stage Ic, preoperative rupture, stages II and III) and histological criteria such as high mitotic count.[7 ]
Treatment of Childhood Sex Cord–Stromal Tumors
Treatment options for childhood sex cord–stromal tumors include the following:
A French registry identified 38 girls younger than 18 years with ovarian sex cord tumors.[4 ] Complete surgical resection was achieved in 23 of 38 girls who did not receive adjuvant treatment. Two patients recurred, one patient's tumor responded to chemotherapy, and the other patient died. Fifteen girls had tumor rupture and/or ascites. Eleven of the 15 patients received chemotherapy and did not recur; of the four patients who did not receive chemotherapy, all recurred and two died.
Childhood Juvenile Granulosa Cell Tumors
The most common histologic subtype in girls younger than 18 years is juvenile granulosa cell tumors (median age, 7.6 years; range, birth to 17.5 years).[8 ,9 ] Juvenile granulosa cell tumors represent about 5% of ovarian tumors in children and adolescents and are distinct from the granulosa cell tumors seen in adults.[1 ,10 ,11 ,12 ]
- Precocious puberty (most common; caused by estrogen secretion).
- Abdominal pain.
- Abdominal mass.
Treatment of Childhood Juvenile Granulosa Cell Tumors
Treatment options for childhood juvenile granulosa cell tumors include the following:
- Surgery. As many as 90% of children with juvenile granulosa cell tumors will have low-stage disease (stage I) by International Federation of Gynecology and Obstetrics (FIGO) criteria and are usually curable with unilateral salpingo-oophorectomy alone.
- Chemotherapy. Patients with spontaneous tumor rupture or malignant ascites (FIGO stage IC2, IC3), advanced disease (FIGO stages II–IV), and those with high mitotic activity tumors have a poorer prognosis and require chemotherapy.[4 ,6 ,17 ] Use of a cisplatin-based chemotherapy regimen has been reported in both the adjuvant and recurrent disease settings with some success.[6 ,8 ,12 ,18 ,19 ][Level of evidence: 3iiiA]
Childhood Sertoli-Leydig Cell Tumors
Incidence, Risk Factors, and Clinical Presentation
Sertoli-Leydig cell tumors are rare in young girls and are more frequently seen in adolescents. They may secrete androgens and, thus, present with virilization, secondary amenorrhea,[20 ] or precocious puberty.[21 ] These tumors may also be associated with Peutz-Jeghers syndrome, but more frequently are a part of the DICER1-tumor spectrum.[2 ,22 ,23 ] Patients with Sertoli-Leydig cell tumors should be evaluated for germline DICER1 mutations. If a germline DICER1 mutation is found, regular follow-up for ovarian and other tumors such as thyroid disease (multinodular goiter, carcinoma) and genetic counseling should be considered.[23 ,24 ]
Treatment and Outcome of Childhood Sertoli-Leydig Cell Tumors
Treatment options for childhood Sertoli-Leydig cell tumors include the following:
- Surgery. Surgery is the primary treatment for Sertoli-Leydig cell tumors and is the only treatment for low-stage disease (FIGO stage Ia), with essentially 100% event-free survival (EFS).[4 ][Level of evidence: 3iiiA] However, up to 10% of patients may develop metachronous contralateral tumors, particularly in the context of underlying DICER1 germline mutations.[25 ]
- Chemotherapy. Patients with Sertoli-Leydig cell tumors with abdominal spillage during surgery, spontaneous tumor rupture, or metastatic disease (FIGO stages IC, II, III, and IV) are treated with cisplatin-based combination chemotherapy, although the impact of chemotherapy has not been studied in clinical trials.[4 ,26 ] An additional study reported on 40 women with FIGO stage I or Ic Sertoli-Leydig cell tumors of the ovary, with an average age of 28 years.[27 ][Level of evidence: 3iiA] Of 34 patients with intermediate or poor differentiation, 23 patients received postoperative chemotherapy (most regimens included cisplatin); none recurred. Of the 11 patients who did not receive postoperative chemotherapy, two recurred; both had tumors that were salvaged with chemotherapy.
A study of 44 patients from the European Cooperative Study Group on Pediatric Rare Tumors showed that prognosis of Sertoli-Leydig cell tumors was determined by stage and histopathologic differentiation.[26 ]

Childhood Small Cell Carcinoma of the Ovary, Hypercalcemia-Type
Incidence, Molecular Features, and Prognosis
Small cell carcinomas of the ovary are exceedingly rare and aggressive tumors and may be associated with hypercalcemia.[1 ]
SMARCA4 mutations have been described in these tumors, putting these in the context of rhabdoid tumors.[2 ]
The clinical course is usually aggressive and prognosis is poor.
Treatment of Childhood Small Cell Carcinoma of the Ovary, Hypercalcemia-Type
Treatment options for childhood small cell carcinoma of the ovary include the following:
- Aggressive multimodality therapy. Successful treatment with aggressive therapy has been reported in a few cases.[1 ,3 ][Level of evidence: 3iiB]; [4 ,5 ][Level of evidence: 3iiiA]
- Tazemetostat. Tazemetostat is an EZH2 inhibitor that demonstrates activity against preclinical models of small cell carcinoma of the ovary with SMARCA4 loss.[6 ] Two patients with small cell carcinoma of the ovary and SMARCA4 loss were enrolled in a phase I trial of tazemetostat; one patient achieved a partial response and one patient achieved prolonged stable disease.[7 ]

Treatment Options Under Clinical Evaluation for Childhood Ovarian Cancer
Information about National Cancer Institute (NCI)–supported clinical trials can be found on the NCI website. For information about clinical trials sponsored by other organizations, refer to the ClinicalTrials.gov website.
The following are examples of national and/or institutional clinical trials that are currently being conducted:
APEC1621 (NCT03155620) (Pediatric MATCH: Targeted Therapy Directed by Genetic Testing in Treating Pediatric Patients with Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphomas, or Histiocytic Disorders): NCI-COG Pediatric Molecular Analysis for Therapeutic Choice (MATCH), referred to as Pediatric MATCH, will match targeted agents with specific molecular changes identified using a next-generation sequencing targeted assay of more than 4,000 different mutations across more than 160 genes in refractory and recurrent solid tumors. Children and adolescents aged 1 to 21 years are eligible for the trial.
Tumor tissue from progressive or recurrent disease must be available for molecular characterization. Patients with tumors that have molecular variants addressed by treatment arms included in the trial will be offered treatment on Pediatric MATCH. Additional information can be obtained on the NCI website and ClinicalTrials.gov website.
Special Considerations for the Treatment of Children With Cancer
Cancer in children and adolescents is rare, although the overall incidence of childhood cancer has been slowly increasing since 1975.[1 ] Referral to medical centers with multidisciplinary teams of cancer specialists experienced in treating cancers that occur in childhood and adolescence should be considered for children and adolescents with cancer. This multidisciplinary team approach incorporates the skills of the following health care professionals and others to ensure that children receive treatment, supportive care, and rehabilitation that will achieve optimal survival and quality of life:
- Primary care physicians.
- Pediatric surgeons.
- Radiation oncologists.
- Pediatric medical oncologists/hematologists.
- Rehabilitation specialists.
- Pediatric nurse specialists.
- Social workers.
- Child-life professionals.
(Refer to the PDQ Supportive and Palliative Care summaries for specific information about supportive care for children and adolescents with cancer.)
Guidelines for pediatric cancer centers and their role in the treatment of pediatric patients with cancer have been outlined by the American Academy of Pediatrics.[2 ] At these pediatric cancer centers, clinical trials are available for most types of cancer that occur in children and adolescents, and the opportunity to participate in these trials is offered to most patients and their families. Clinical trials for children and adolescents diagnosed with cancer are generally designed to compare potentially better therapy with therapy that is currently accepted as standard. Most of the progress made in identifying curative therapy for childhood cancers has been achieved through clinical trials. Information about ongoing clinical trials is available from the NCI website.
Dramatic improvements in survival have been achieved for children and adolescents with cancer. Between 1975 and 2010, childhood cancer mortality decreased by more than 50%.[3 ] Childhood and adolescent cancer survivors require close monitoring because cancer therapy side effects may persist or develop months or years after treatment. (Refer to the PDQ summary on Late Effects of Treatment for Childhood Cancer for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.)
Childhood cancer is a rare disease, with about 15,000 cases diagnosed annually in the United States in individuals younger than 20 years.[4 ] The U.S. Rare Diseases Act of 2002 defines a rare disease as one that affects populations smaller than 200,000 persons. Therefore, all pediatric cancers are considered rare.
The designation of a rare tumor is not uniform among pediatric and adult groups. Adult rare cancers are defined as those with an annual incidence of fewer than six cases per 100,000 people, and they are estimated to account for up to 24% of all cancers diagnosed in the European Union and about 20% of all cancers diagnosed in the United States.[5 ,6 ] Also, the designation of a pediatric rare tumor is not uniform among international groups, as follows:
- The Italian cooperative project on rare pediatric tumors (Tumori Rari in Eta Pediatrica [TREP]) defines a pediatric rare tumor as one with an incidence of less than two cases per 1 million population per year and is not included in other clinical trials.[7 ]
- The Children's Oncology Group has opted to define rare pediatric cancers as those listed in the International Classification of Childhood Cancer subgroup XI, which includes thyroid cancer, melanoma and nonmelanoma skin cancers, and multiple types of carcinomas (e.g., adrenocortical carcinoma, nasopharyngeal carcinoma, and most adult-type carcinomas such as breast cancer, colorectal cancer, etc.).[8 ] These diagnoses account for about 4% of cancers diagnosed in children aged 0 to 14 years, compared with about 20% of cancers diagnosed in adolescents aged 15 to 19 years.[9 ]
Most cancers within subgroup XI are either melanomas or thyroid cancer, with the remaining subgroup XI cancer types accounting for only 1.3% of cancers in children aged 0 to 14 years and 5.3% of cancers in adolescents aged 15 to 19 years.
These rare cancers are extremely challenging to study because of the low incidence of patients with any individual diagnosis, the predominance of rare cancers in the adolescent population, and the lack of clinical trials for adolescents with rare cancers.
Information about these tumors may also be found in sources relevant to adults with cancer such as the PDQ summary on adult Ovarian Epithelial, Fallopian Tube, and Primary Peritoneal Cancer Treatment.
