Kaplan–Meier estimates for overall survival (OS) from liver metastasis to death according to therapy, considering the impact of surgical resection of liver metastases. (A) Surgical resection of liver metastases indicated a highly significant impact on OS of patients with MUM. (B) In order to avoid corresponding bias, comparison of survival between Cohort 1 and Cohort 2 were additionally performed only for those whose metastases were not surgically resected (n = 31), referred to as Cohort 1.1 (ICI plus liver-directed therapy exclusive surgical treatment) and Cohort 1.2 (monotherapies, combinations of systemic therapy and liver-directed therapies excluding surgical treatment).
