|dc.description.abstract||<jats:sec><jats:title>Introduction</jats:title><jats:p> Selected patients with colorectal cancer liver metastases (CRLM) and synchronous extrahepatic disease (EHD) are considered for surgery. </jats:p></jats:sec><jats:sec><jats:title>Objectives</jats:title><jats:p> To evaluate the change in surgical management and long-term survival (disease-free survival [DFS] and overall survival [OS]) for patients with CRLM and EHD who undergo positron emission tomography combined with computed tomography (PET-CT) vs no PET-CT. </jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p> Patients with CRLM were enrolled in a trial evaluating the effect of PET-CT (vs no PET-CT) on surgical management, DFS, and OS. This is a sub-study of the trial, including only patients with synchronous EHD. Cox proportional hazard models were used to calculate risks for recurrence and death. Survival were described by Kaplan-Meier method and compared with log-rank test. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> Of 25 patients with EHD (PET-CT arm: 14/270 (5%) and no PET-CT arm: 11/134 (8%)), PET-CT changed surgical management in 14%, all of which avoided liver resection due to more extensive disease. Complete metastasectomy was achieved in 36% (5/14) and 72% (8/11), respectively. Respectively, PET-CT vs no PET-CT had statistically similar median DFS, 5.6 months (95% confidence interval (CI) 3.6-18) vs 7.6 months (95% CI 2.9-15) and median OS, 42 months (95% CI 25-48) vs 29 months (95% CI 17-41). EHD was associated with worse DFS (hazard ratio HR = 1.89, 95% CI 1.41-2.52) and OS (HR = 2.47, 95% CI 1.6-3.83). </jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p> Preoperative PET-CT for the management of resectable CRLM did not improve long-term outcomes among patients who had synchronous EHD; however, it changed surgical management in a relatively significant proportion of patients. </jats:p></jats:sec>||-|
