Insights
Pediatric teratomas, especially sacrococcygeal, require early recognition and complete surgical excision for optimal outcomes. Early presentation and mature histology significantly improve survival rates in children under 12.
Area of Science:
- Pediatric Oncology
- Surgical Pathology
- Developmental Biology
Background:
- Teratomas are congenital tumors with diverse histology and locations.
- In pediatric patients, early diagnosis and treatment are crucial for prognosis.
Purpose of the Study:
- To review clinicopathological features of pediatric teratomas.
- To identify prognostic factors influencing outcomes in young patients.
Main Methods:
- Retrospective review of 75 pediatric teratoma cases under 12 years.
- Analysis of tumor site, histology, treatment, and survival data.
Main Results:
- Most common site: sacrococcygeum (49/75); 74% presented within the first year of life.
- Complete excision yielded 95% survival for mature teratomas; immature/malignant types required multimodal therapy.
- Age at presentation and histology impacted prognosis, particularly for sacrococcygeal teratomas.
Conclusions:
- Early recognition and complete surgical excision are vital for pediatric teratomas.
- Histology and age at presentation are key prognostic indicators.
- Multimodal therapy improves outcomes for immature and malignant teratomas.
Abstract:
The clinicopathological features of 75 children under the age of 12 years with teratomas are reviewed. Tumors arose in the following anatomic sites: sacrococcygeum (n = 49), ovary (n = 10), Testis (n = 5), oral cavity (n = 3), retroperitoneum (n = 2) and others (n = 6). Fifty five (74%) presented within the first year of life. Excluding the gonadal tumors, male-female ratio was 2:5. Majority of the tumors had only mature tissues. Such patients and those 9 patients in whom the histology was not specified, underwent excision alone and had 95% early survival rates. Five patients had admixture of mature and immature tumors. Nine patients had malignant tissues. Germ cell tumors containing only malignant component, but no mature or immature teratomatous tissues were excluded from the series. The patients with immature and malignant tissues underwent multimodal therapy including surgical excision, multiagent chemotherapy (VAC regimen) and at times radiotherapy. Mortality in patients with immature and malignant teratomas was 20 and 66.7%, respectively. Besides histology, the only factor which affected prognosis, especially in case of sacrococcygeal teratomas was the age at the time of presentation. Our experience highlights the importance of early recognition and complete surgical excision of teratomas in the pediatric age group.
