Quality of life and neuropsychological evaluation for patients with malignant astrocytomas: RTOG 91-14. Radiation Therapy Oncology Group.

With increasingly aggressive neurosurgical and radiation therapy modalities (gamma knife, external beam stereotactic radiation and interstitial brachytherapy with or without hyperthermia) offered to patients with malignant astrocytomas (MA), increasing national demand for medical outcome studies and rising health care costs amidst public, business, and governmental debate to cut spending, we as physicians are obligated to continue our research to find effective treatments for malignant astrocytoma (MA) and a cost-effective means to study their impact upon the patient's quality of life (QOL).

OBJECTIVE

We report data that was collected within the Radiation Therapy Oncology Group (RTOG) on 126 patients with MA who were enrolled in RTOG 91-14. This study was undertaken to prospectively test the feasibility of performing quality of life (QOL) and neuropsychological evaluation (NPE) and collecting this data within the RTOG.

RESULTS

The NPE and QOL parameters that were used in this study are cost effective. They are not only much cheaper than formal cognitive and memory testing, but also provide additional information regarding the patients' day to day functional abilities that are not provided by the current routinely used means, such as KPS. The Mini-Mental Status Exam (MMSE) provides greater sensitivity to patients' differences in neurological status and may be preferable to NFS as an eligibility criteria.
