15.9 (range, 1.2-57.0) months, the number of metastatic lesions, 2D-tumor size, and 3D-tumor volume showed significant correlation with OS, PFS and PFS-2 in a continuous manner (e.g., 1-5, 6-10, 11-20 and >20; ≤ 10 cm, 10-20 cm, 20-40 cm and >40 cm; and ≤ 10 cc, 10-30 cc, 30-130 cc and > 130cc, respectively). In multivariate analysis, tumor involvement in liver (hazard ratio [HR] 1.79) and brain (HR 5.52) were independently associated with poor OS along with quantitative characteristics.
