Influence of gamma knife radiosurgery on the quality of life in patients with brain metastases. Academic Article uri icon

Overview

abstract

  • Quality of life (QOL) is an important issue in the treatment of patients with brain metastases. With median survival times often less than 4 months, less invasive treatment options that maximize QOL parameters are essential. In recent years, stereotactic radiosurgery (SRS) has been commonly used as a noninvasive alternative to surgical resection for such patients. This prospective study was undertaken to evaluate QOL in patients undergoing SRS for brain metastases. Between 1999 and 2000, 20 patients with metastatic disease to the brain were evaluated and treated in our Gamma Knife unit. All patients performed the Spitzer QOL survey (10-point scale) both before stereotactic radiosurgery and at each follow-up visit. Primary sites of disease included lung (n = 10), breast (n = 5), melanoma (n = 2), thyroid (n = 1), uterine (n = 1), and kidney (n = 1). Fifteen (75%) had prior whole brain radiotherapy (median dose: 35 Gy). The median age and Karnofsky Performance Status were 58 years and 80, respectively. The median Spitzer score before SRS was 9 (range: 7-10), and the median follow-up time of the patients in this series was 7 months. The median posttreatment Spitzer score at 1 and 3 months after SRS was 9 (range: 5-10) and 8 (range: 4-10), respectively. Crude intracranial tumor control in this cohort of patients was 90%. Extracranial tumor progression was noted in 8 patients (40%), and in these patients, Spitzer scores tended to decrease in value. In those patients who had no evidence of intracranial or extracranial tumor progression, Spitzer scores remained either unchanged or improved. Gamma knife SRS is an appropriate treatment modality for maintaining QOL parameters in patients with brain metastases. Tumor progression both intracranially and extracranially influences QOL parameters. Confirmation of this finding will require further investigation.
