Ovarian neoplasms in children

Area of Science:

• Pediatric Oncology
• Gynecologic Oncology
• Tumor Biology

Background:

• Ovarian neoplasms are uncommon in children.
• Germ-cell tumors are the predominant type in pediatric patients, differing from adult populations.
• Clinical presentation varies, including abdominal pain, mass, or hormonal disturbances.

Purpose of the Study:

• To review the clinical presentation, treatment, and outcomes of ovarian neoplasms in pediatric patients.
• To analyze the types, stages, and survival rates of these tumors.
• To identify prognostic factors and treatment responses.

Main Methods:

• Retrospective review of medical records for 29 girls with ovarian neoplasms treated between 1976 and 1992.
• Analysis of patient demographics, tumor characteristics, treatment modalities, and outcomes.
• Follow-up duration ranged from 6 months to 7.5 years, averaging 3.0 years for malignant cases.

Main Results:

• Seventeen tumors were benign and 12 were malignant; germ-cell tumors predominated (n=17).
• Most malignant neoplasms (7/10) were diagnosed at stage I.
• Overall survival was high (100% for benign, 70% for malignant), but aggressive behavior was noted in some malignant types, including sex cord/stromal tumors.

Conclusions:

• Ovarian tumors in children are rare and typically germ-cell in origin.
• While many are benign, some malignant pediatric ovarian tumors exhibit aggressive behavior and poor response to adjuvant therapy.
• Malignant sex cord/stromal cell tumors warrant particular attention due to their unpredictable nature, even at early stages.
