Simultaneous resection of primary tumour and liver metastasis for colorectal cancer with synchronous liver metastases: a single centre experience

Introduction: Approximately 22% of patients with colorectal cancer present with synchronous metastases. More patients are undergoing resection of liver metastases as surgical strategies and neoadjuvant treatments advance, shifting management from palliation to disease control. Surgical management of colorectal cancer with synchronous liver metastases is traditionally performed separately. Multiple retrospective simultaneous surgery reports deem synchronous resection feasible but outcome data are heterogeneous data and limited. The aim of this study was to analyse the experience of simultaneous resection of the primary tumour and liver metastasis at a UK tertiary centre with attention to surgical, oncological outcomes and survival benefit.
