KPS (HR = 0.932, CI [0.884; 0.990], p = 0.020) and bone metastases as the SBRT treating site (HR = 0.225, CI [0.065; 0.775], p = 0.018; Figure 3C ) appeared to be significant favorable prognostic factors in univariate analysis ( Table 4 ), with the overall number of one metastasis at borderline significance level (HR = 0.371, CI [0.134; 1.025], p = 0.056).
