A categorization by surgical resection of liver metastases demonstrated a highly significant difference ( p = 0.005) in OS between those patients who underwent surgical resection (median OS 32.8 months; 95% CI, 21.42–44.18; n = 11) and those who did not (median OS 12.20 months; 95% CI; 5.58–18.82, n = 31) ( Figure 3 A).
