Abstract
Background
Two-stage liver resection (2-SLR) is used clinically in conjunction with portal vein embolization for bilobar disease to increase the number of patients suitable for liver resection. The long-term outcomes after 2-SLR for multiple bilobar colorectal liver metastases (CLM) was examined.
Methods
Patients who sought care between November 2003 and April 2006 with multiple CLM considered suitable for 2-SLR were prospectively followed. Clinicopathological data were collected. Surgical outcomes were defined as complete clearance of tumor (R0/R1/R2), postoperative morbidity (within 3 months), 30 day mortality, disease-free survival (DFS), and overall survival (OS).
Results
A total of 131 patients with CLM underwent liver resection during the study period, 38 of whom were planned for a 2-SLR for multiple bilobar disease. Only 33 (87%) completed the 2-SLR with a curative intent. Five patients did not undergo stage II resection because of disease progression. The postoperative morbidity was 11 and 33% after stage I and stage II liver resections, respectively. Five patients (13%) encountered postoperative complications specific to liver surgery. The median interval from stage II resection to disease recurrence in the R0 group was 18 months versus 3 months in the R1/R2 group (P < 0.001). R0 resection with curative intent versus R1/R2 noncurative resection has a significantly longer period of DFS (P < 0.001) and OS (P = 0.04).
Conclusions
The 2-SLR combined with portal vein embolization is an effective and safe method for resecting previously unresectable multiple bilobar CLM. However, a positive resection margin leads to poor DFS and OS.
