Summary
Germ cell tumors (GCTs) in newborns are mostly teratomas, treatable with surgery. Even malignant GCTs, like yolk sac tumors, are likely curable with chemotherapy.
Area of Science:
- Oncology
- Developmental Biology
- Pediatric Pathology
Background:
- Germ cell tumors (GCTs) originate from primordial germ cells.
- GCTs exhibit diverse histology and behavior due to pluripotency.
- Fetal and neonatal GCTs present a narrower clinical and histological spectrum.
Purpose of the Study:
- To review the distinct characteristics of GCTs in fetuses and neonates.
- To highlight the typical histologies and prognoses of GCTs in early life.
- To discuss current and potential future therapeutic strategies for neonatal GCTs.
Main Methods:
- Review of pediatric oncology literature focusing on GCTs in neonates.
- Analysis of histological subtypes and clinical outcomes.
- Synthesis of information on treatment efficacy and emerging research.
Main Results:
- Neonatal GCTs are predominantly mature and immature teratomas, often curable with surgery.
- Malignant neonatal GCTs, primarily yolk sac tumors, show high curability with cisplatin-based chemotherapy.
- Understanding germline development aberrations offers insights into GCT genesis and treatment.
Conclusions:
- GCTs in fetuses and neonates have a more limited presentation than in older individuals.
- Surgical resection is the primary treatment for most neonatal GCTs.
- Chemotherapy, particularly cisplatin-based regimens, is effective for malignant neonatal GCTs, offering a high chance of cure.
