Prognostic factors in neuroblastic tumors
Journal of Pediatric Surgery
|June 1, 1976
Summary
This study analyzed 101 neuroblastic tumor cases from 1950-1974. Younger age and less advanced clinical stage were key predictors of survival in malignant neuroblastic tumors.
Area of Science:
- Pediatric Oncology
- Tumor Biology
- Clinical Data Analysis
Background:
- Neuroblastic tumors represent a significant challenge in pediatric oncology.
- Understanding long-term outcomes and prognostic factors is crucial for patient management.
Purpose of the Study:
- To analyze outcomes for neuroblastic tumors treated between 1950 and 1974.
- To identify independent predictors of survival and develop prognostic models.
Main Methods:
- Multifactorial analysis of 101 neuroblastic tumor cases.
- Data abstracted from patient records at The Johns Hopkins Hospital (1950-1974).
- Evaluation of factors including tumor site, histologic differentiation, age, and clinical stage.
Main Results:
- Overall cure rate for malignant tumors was 39%.
- Favorable prognostic indicators included extra-abdominal primary, mature histologic differentiation, and surgical excision.
- Age less than 2 years and less extensive clinical stage were independent predictors of survival.
- Radiotherapy and chemotherapy showed no significant benefit during this period.
Conclusions:
- Prognostic models incorporating stage, age, and histologic differentiation demonstrated 95% accuracy.
- These models may aid in managing malignant neuroblastic tumors and assessing treatment efficacy.
- Further evaluation is needed to refine prognostic tools for neuroblastic tumors.
