Fig. 2. Survival results. (A) Synchronous versus metachronous survival analysis, by log-rank test (P = 0.327, by log-rank) (1, metachronous; 2, synchronous). (B) Survival from first metastatetomy by log-rank test (P = 0.813, by log-rank). (C) Comparison between liver metastases involving single lobe or both lobe in survival from first site metastasectomy (P = 0.031, by log-rank). (D) Comparison between single and multiple lung metastasis in survival from first site metastasectomy (P = 0.784, by log-rank).
