Impact of Positron Emission Tomography Imaging Prior to Liver Resection for Colorectal Adenocarcinoma Metastases

The purpose of this trial is to improve the management of patients with potentially surgically curable colorectal cancer liver metastases.
The primary objective is to determine the impact of pre-operative positron emission tomography (PET) on patients who have been assessed as having resectable colorectal cancer liver metastases by conventional imaging (computed tomography (CT) abdomen/thorax, colonoscopy), by determining the proportion of patients who have a change in management resulting from PET.

本临床试验旨在优化潜在可经手术根治的结直肠癌肝转移（colorectal cancer liver metastases）患者的诊疗管理流程。
其主要研究目标为明确术前正电子发射断层扫描（positron emission tomography, PET）对经常规影像学检查[含腹部/胸部计算机断层扫描（computed tomography, CT）及结肠镜检查]评估为可切除结直肠癌肝转移患者的影响，具体通过统计因PET检查结果导致诊疗方案变更的患者占比来达成。
