Sacrococcygeal teratomas in infants and children
Insights
Sacrococcygeal teratomas are common in neonates, with benign types having a good prognosis. Malignant sacrococcygeal teratoma presents a poor prognosis, regardless of treatment.
Area of Science:
- Pediatric Surgery
- Oncology
- Pathology
Background:
- Sacrococcygeal teratoma (SCT) is a significant congenital tumor.
- This study analyzes a large cohort of SCT patients over four decades.
Purpose of the Study:
- To investigate the clinical characteristics and outcomes of sacrococcygeal teratoma.
- To determine prognostic factors, including tumor type and patient age.
Main Methods:
- Retrospective review of 66 patients with sacrococcygeal teratoma diagnosed between 1941 and 1983.
- Analysis of tumor histology (benign, malignant, embryonic components) and patient demographics.
Main Results:
- SCT represented 41% of all teratomas seen. Females and neonates were predominantly affected.
- Benign tumors had a good prognosis. Malignant SCT (29% of cases) had a very poor prognosis, with only one survivor out of 19 patients.
- Tumors with mature or embryonic tissues showed a good prognosis, while those with malignant components indicated a bleak outlook.
Conclusions:
- Early diagnosis and management of sacrococcygeal teratoma are crucial.
- Tumor histology is a critical determinant of prognosis, with malignant SCT requiring aggressive therapeutic strategies.
Abstract:
From 1941 through 1983, a total of 66 patients with sacrococcygeal teratoma were seen, representing 41 percent of the total of 162 patients with teratomas from all anatomic sites seen over this period. Forty-six (70 percent) of the patients with sacrococcygeal teratomas were female and 34 (52 percent) were neonates. Younger patients had a significantly better prognosis. Approximately half (48 percent) of the patients had benign tumors. Of the other 34 patients, 19 (29 percent) had frank malignancy, being either a purely malignant tumor or a tumor with malignant mixed with benign elements, and 15 (23 percent) patients had tumors containing embryonic but no malignant components. Patients with tumors containing mature adult or embryonic tissues have a good prognosis. However, malignant sacrococcygeal teratoma portends a bleak prognosis irrespective of therapy (in this series only one patient survived among 19 patients with an average survival of 16 months after diagnosis).
