Results of patient survival and local tumor control. (a) Survival results: The solid line represents overall survival (OS) probability. The median survival time was 11.8 months (95% CI: 5.5-15.6). One- and 2-year OS rates after stereotactic radiosurgery (SRS) were 47% and 20%, respectively. The dotted line represents the neurological death (ND)-free survival probability adjusted for competing events. The 1- and 2-year ND-free survival rates after SRS were 91% and 84%, respectively. Note that the distance between these two lines represents the cumulative incidence of non-neurological death. (b) Local tumor control rates: Six- and 12-month local tumor control rates were 85% and 64%, respectively.
