Scale for assessing quality of life of children survivors of cranial posterior fossa tumors.
BACKGROUND
Evaluation of quality of life of survivors of brain tumors is an important aspect of outcome that must be included in clinical studies.


METHODS
We have developed a new scale for assessing quality of life (QL) of pediatric long-term survivors of posterior fossa tumors based on their physical, psychointellectual, and endocrine/growth status. We have studied 39 patients, with a median follow-up of 9 years. Twenty-five had cerebellar astrocytoma (CA), 6 medulloblastoma (MDB), 5 brain-stem glioma (BSG) and 3 ependymoma of IV ventricle (EPD).


RESULTS
Sixty-six percent of children showed neurologic and/or visual sequelae. Little or no significant disability (Bloom's levels I-II) were present in 66%. Psychointellectual dysfunction was present in 44%, with an IQ < 90 in 39%. Endocrine and growth disorders were found in 26%, mostly stature anomalies. According to our scale, QL scores were high in 19 patients (49%), intermediate in 8 (20%), and low in the remaining 12 (31%). Unfavourable outcomes were related to age of less than 4 years, tumors other than CA (MDB, BSG, EPD), incomplete tumoral resection, and employment of radiotherapy and chemotherapy.


CONCLUSIONS
Our results are comparable to others previously reported, and this supports the validity of our scale. We consider that this scale is applicable to evaluate QL of children survivors of cranial tumors.
