Predictors of quality of life and survival following Gamma Knife surgery for lung cancer brain metastases: a prospective study.

OBJECTIVE Lung cancer (LC) patients who develop brain metastases (BMs) have a poor prognosis. Estimations of survival and risk of treatment-related deterioration in quality of life (QOL) are important when deciding on treatment. Although we know of several prognostic factors for LC patients with BMs, the role of QOL has not been established.

Quality of life is maintained using Gamma Knife radiosurgery: a prospective study of a brain metastases patient cohort.

OBJECTIVE Gamma Knife radiosurgery (GKRS) is increasingly used in the management of brain metastases (BMs), but few studies have evaluated how GKRS impacts quality of life (QOL). The aim of this study was to monitor QOL as the primary end point following GKRS in a patient cohort with BM. METHODS The study included 97 consecutive patients with 1-6 BMs treated with GKRS between May 2010 and September 2011.

Gamma knife surgery as monotherapy with clinically relevant doses prolongs survival in a human GBM xenograft model.

Object: Gamma knife surgery (GKS) may be used for recurring glioblastomas (GBMs). However, patients have then usually undergone multimodal treatment, which makes it difficult to specifically validate GKS independent of established treatments. Thus, we developed an experimental brain tumor model to assess the efficacy and radiotoxicity associated with GKS.
