Health-related quality of life of patients with brain metastases selected for stereotactic radiosurgery.

ABSTRACT: PURPOSE:Information on health-related quality of life (HRQoL) of patients with brain metastases (BM) before stereotactic radiosurgery (SRS) is very relevant to improve communication between patients and clinicians and to be able to interpret changes in HRQoL after SRS. The aim of this study was to evaluate the prevalence and severity of complaints on different aspects of pre-SRS HRQoL among patients with BM and to identify predictors thereof. METHODS:Patients with 1-10 newly diagnosed BM, expected survival >?3 months, Karnofsky Performance Status ??70, and scheduled to undergo SRS were included. HRQoL was measured with the Functional Assessment of Cancer Therapy-Brain (FACT-Br) questionnaire. One-sample z-tests were conducted to analyze differences between patients with BM and published normative data of a general adult sample and of an adult cancer sample. Multiple regression analyses were run to identify predictors of pre-SRS HRQoL. RESULTS:On the individual level, most patients with BM (57.6% of 92 included patients) reported complaints regarding emotional well-being. As a group, patients with BM reported significantly lower emotional well-being compared to both control groups and significantly higher social well-being compared to the general population. Worse psychological factors, e.g. physical fatigue, depression, mental fatigue and anxiety, predicted aspects of pre-SRS HRQoL. CONCLUSIONS:An increased understanding of pre-SRS HRQoL and predictors hereof, provides us with more insight into the well-being of our patients with BM and is necessary for the interpretation of (changes in) HRQoL after SRS.

Project description:PURPOSE:Information on predictive factors of cognitive functioning in patients with (multiple) brain metastases (BM) selected for radiosurgery may allow for more individual care and may play a role in predicting cognitive outcome after radiosurgery. The aim of this study was to evaluate cognitive performance, and predictors thereof, in patients with 1-10 BM before radiosurgery. METHODS:Cognition was measured before radiosurgery using a standardized neuropsychological test battery in patients with 1-10 BM (expected survival > 3 months; KPS ≥ 70; no prior BM treatment). Regression formulae were constructed to calculate sociodemographically corrected z scores. Group and individual cognitive functioning was analyzed. Multivariable regression was used to explore potential predictors. RESULTS:Patients (N = 92) performed significantly worse than controls (N = 104) on all 11 test variables (medium-large effect sizes for 8 variables). Percentages of impairment were highest for information processing (55.3%), dexterity (43.2%) and cognitive flexibility (28.7%). 62% and 46% of patients had impairments in at least two, or three test variables, respectively. Models including combinations of clinical and psychological variables were predictive of verbal memory, psychomotor speed, information processing and dexterity. Neither number nor volume of metastases predicted patients' test performance. CONCLUSIONS:Already before radiosurgery, almost half of the patients suffered from severe cognitive deficits in at least three test variables. At group and individual level, information processing, cognitive flexibility, and dexterity were most affected. These cognitive impairments may impair daily functioning and patients' ability to make (shared) treatment decisions. Both clinical (symptomatic BM; timing of BM diagnosis) and psychological (mental fatigue) characteristics influenced cognitive performance.

Project description:Introduction:Due to the neurocognitive side effects of whole brain radiation therapy (WBRT), stereotactic radiosurgery (SRS) is being used with increasing frequency. The use of SRS is expanding for patients with multiple (>4) brain metastases (BM). This study summarizes our institutional experience with single-fraction, linear-accelerator-based SRS for multiple BM. Methods and materials:All patients who were treated between January 1, 2013, and September 30, 2015, with single-fraction SRS for ?4 BM were included in this institutional review board-approved, retrospective, single-institution study. Patients were treated with linear accelerator-based image guided SRS. Results:A total of 59 patients with ?4 BM were treated with single-fraction SRS. The median follow-up was 15.2 months, and the median overall survival for the entire cohort was 5.8 months. The median number of treated lesions per patient was 5 (range, 4-23). Per patient, the median planning target volume (PTV) was 4.8?cc (range, 0.7-28.8?cc). The prescribed dose across all 380 BM for the 59 patients ranged from 7 to 20?Gy. The median of the mean dose to the total PTV was 19.5?Gy. Although the number of treated lesions (4-5 vs ?6) did not influence survival, better survival was noted for a total PTV <10?cc versus ?10?cc (7.1 vs 4.2 months, respectively; P?=?.0001). A mean dose of ?19?Gy to the entire PTV was also associated with increased survival (6.6 vs 5.0 months, respectively; P?=?.0172). Patients receiving a dose of >12?Gy to ?10?cc of normal brain had worse survival (5.1 vs 8.6 months, respectively; P?=?.0028). Conclusion:In single-fraction SRS for patients with multiple BM, smaller total tumor volume, higher total dose, and lower volume of normal brain receiving >12?Gy were associated with increased survival. These data suggest that using SRS for the treatment of multiple BM is efficacious and that outcomes may be affected more by total tumor volume than by the number of lesions.
