BACKGROUND: @entity1 with synchronous colorectal liver @entity3 are thought to have a less favorable prognosis than those with @entity14 alone. Surgical treatment options are controversial, be it synchronous resection or staged resection. This study compared the clinical, perioperative, disease-free survival (DFS), and @entity1349 ( @entity1349 ) results of @entity1 undergoing synchronous resection versus staged resection. METHODS: An observational cohort study of 103 @entity1 with synchronous colorectal liver @entity3 was performed. All data were collected prospectively. Clinical, perioperative, DFS, and @entity1349 results of @entity1 undergoing synchronous resection (group I, n = 73) and staged resection (group II, n = 30) were compared. RESULTS: More @entity1 in group I had poorly differentiated @entity14 , bilobar liver @entity3 , more than three liver @entity3 , < or =4 cm liver @entity3 , and shorter hospital stays than @entity1 in group II. There were no significant statistically differences in DFS and @entity1349 between the two groups. The median DFS of groups I and II were 28 and 26 months, respectively (p = 0.585). The median @entity1349 of groups I and II were 37 and 36 months, respectively (p = 0.900). CONCLUSIONS: Synchronous resection achieved DFSs and OSs similar to those seen after staged resection while avoiding a second major operation.
