[Testicular yolk sac tumor in children. Current view on diagnosis and treatment]
Insights
Yolk-sac tumors in children can be effectively staged using serum alpha-fetoprotein and retroperitoneal ultrasonography. Treatment is individualized by stage, with radical orchiectomy often curative for early-stage disease.
Area of Science:
- Pediatric Oncology
- Urologic Oncology
- Diagnostic Imaging
Context:
- Yolk-sac tumors (testicular embryonal carcinoma) are rare in children.
- Accurate staging is crucial for effective treatment planning.
- Previous diagnostic and therapeutic approaches varied.
Purpose:
- To evaluate the utility of serum alpha-fetoprotein and retroperitoneal ultrasonography in staging pediatric yolk-sac tumors.
- To assess the outcomes of a multimodal treatment approach.
- To emphasize stage-specific therapeutic strategies.
Summary:
- Five children with yolk-sac tumors were treated between 1973 and 1981.
- Serum alpha-fetoprotein levels and retroperitoneal ultrasonography were key in predicting tumor stage.
- Treatment involved orchiectomy, lymphadenectomy, and chemotherapy (T2-protocol) in some cases.
- All patients achieved recurrence-free survival for 1.5 to 8 years.
- Stage-I tumors were successfully treated with orchiectomy alone.
Impact:
- Highlights the importance of non-invasive diagnostic tools for pediatric testicular tumors.
- Demonstrates the efficacy of individualized, stage-adapted therapy for yolk-sac tumors.
- Provides evidence for successful long-term outcomes in a small cohort, informing future treatment protocols.
Abstract:
5 children with yolk-sac tumor of the testis (= infantile embryonal carcinoma) were admitted to our hospital between 1973 and 1981. Evaluation of serum alpha-fetoprotein concentrations and ultrasonography of the retroperitoneal area proved to be extremely valuable to predict the tumor stage in these children. Therapy consisted of high inguinal orchiectomy, retroperitoneal lymphadenectomy and cytostatic chemotherapy in 3 children using the T2-protocol. All children are now between 1 1/2 and 8 years free of recurrence and metastases. Therapy of this tumor ought to be differentiated according to the individual tumor stage. Most patients with stage-I tumor require only radical orchiectomy for cure.
