Residual disabilities in children treated for intracranial space-occupying lesions
Insights
Long-term survivors of cranial irradiation often experience physical and mental handicaps, particularly those treated before age 11. These cognitive deficits may worsen over time, impacting quality of life after brain tumor treatment.
Area of Science:
- Neuro-oncology
- Pediatric oncology
- Radiation oncology
Background:
- Intracranial space-occupying lesions require treatments like cranial or craniospinal irradiation.
- Long-term survival after such treatments raises questions about late effects.
- Understanding the sequelae of radiation therapy is crucial for patient care.
Purpose of the Study:
- To assess the long-term physical and mental outcomes in survivors of cranial or craniospinal irradiation.
- To identify factors influencing the development of handicaps post-treatment.
- To investigate the progression of cognitive impairments.
Main Methods:
- Retrospective study design.
- Analysis of 30 long-term survivors treated for intracranial space-occupying lesions.
- Evaluation of physical and mental handicaps.
Main Results:
- The majority of survivors exhibited physical and mental handicaps.
- Outcomes were more severe in individuals treated before the age of 11 years.
- Handicaps were observed regardless of whether craniospinal or whole-brain irradiation was used.
- Evidence suggests a progressive nature of mental handicap, though difficult to quantify retrospectively.
Conclusions:
- Cranial irradiation for intracranial tumors can lead to significant long-term physical and mental deficits.
- Early-life treatment (before age 11) is associated with more severe outcomes.
- The progressive nature of mental handicap warrants further investigation with prospective studies.
Abstract:
A retrospective study of 30 long-term survivors of cranial or craniospinal irradiation for intracranial space-occupying lesions has demonstrated physical and mental handicaps in the majority. This is most severe in those cases treated before the age of 11 years, and is not confined to those children having craniospinal or whole-brain irradiation. The mental handicap also appears to be progressive, but cannot be easily examined in this retrospective study.
