IV-S neuroblastoma: a cooperative study of 30 children
Insights
Infants with stage IV-S neuroblastoma require prompt intervention, especially if vital organs like the liver are compressed. Radiation therapy is recommended over chemotherapy due to severe toxicity risks in infants.
Area of Science:
- Pediatric Oncology
- Oncology
- Clinical Pediatrics
Background:
- Stage IV-S neuroblastoma is a specific subtype affecting infants.
- This study reviews clinical features and treatment outcomes in a cohort of young patients.
Purpose of the Study:
- To analyze the clinical characteristics of stage IV-S neuroblastoma in infants.
- To identify prognostic factors and guide therapeutic strategies for this rare condition.
Main Methods:
- Retrospective review of 30 children diagnosed with stage IV-S neuroblastoma between 1970-1981.
- Analysis of patient demographics, primary tumor sites, metastatic patterns, and treatment interventions.
Main Results:
- Stage IV-S neuroblastoma represented 6.1% of all neuroblastoma cases. The mean age at diagnosis was 3 months, with adrenal glands being the most common primary site. Liver involvement was frequent (87%). Age under 2 months and signs of vital organ compromise (pulmonary, renal, hepatic) were unfavorable prognostic indicators.
- Tumor size and subcutaneous nodules did not significantly impact prognosis.
- Chemotherapy-related complications, including fatalities, were noted in infants, highlighting treatment-related risks.
Conclusions:
- Prompt intervention is crucial for infants with stage IV-S neuroblastoma experiencing vital organ compression.
- Radiation therapy is favored over chemotherapy due to its toxicity profile in this age group.
- The findings underscore the need for careful consideration of treatment-related morbidities in infant neuroblastoma management.
Abstract:
The clinical features of 30 children with IV-S neuroblastoma have been reviewed. They were treated at 11 Italian pediatric institutions in the period 1970-1981. Patients with IV-S neuroblastoma comprise 6.1% of all the neuroblastoma cases observed during that period. The age at diagnosis ranged from birth to 11 months (mean, 3 months). The distribution of "primary" lesions was of interest. The adrenal gland was affected most often (57% of patients), but tumors of the chest and neck were also encountered. No specific "primary" lesion was identified in ten children. The most frequent site of widespread disease was the liver (87%). Neither the size of the "primary" tumor, nor the number or size of subcutaneous nodules was of prognostic significance. Unfavorable features were age less than 2 months and clinical signs of pulmonary, renal, or hepatic embarrassment. These data confirm the need for prompt intervention in the infant who is suffering from compression of these vital structures by the enlarged liver. Radiation therapy is to be preferred for this purpose, because of the often severe toxicity that is associated with chemotherapy in infants. One, and possibly two babies in this series died of chemotherapy-related complications.
