Abstract
Background
The surgery for the treatment of multiple (≥5) bi-lobar hepatic metastases from colorectal cancer is controversial. This retrospective study presents our experience in an attempt to develop reasonable treatment guidelines.
Method
One hundred sixty-one consecutive patients who underwent liver resection with curative intent were classified into three groups: H1 (unilateral), H2 (bilateral, ≤4 nodules), or H3 (bilateral, ≥5 nodules).
Results
The overall cumulative 5-year survival rate was 46.7%. Survival was similar among patients with H1, H2, and H3 disease. Thirty-two patients with H3 disease underwent hepatectomy: straightforward hepatectomy in 12, portal vein embolization (PVE) prior to hepatectomy in eight, two-stage hepatectomy in two, and two-stage hepatectomy combined with PVE in ten. Two-stage hepatectomy with or without PVE was the standard approach in patients with synchronous liver metastases. The operating mortality in hepatectomy for H3 disease was 0%, and the morbidity was 15.2%. The overall response rate to neoadjuvant chemotherapy (NAC) was 41.7% (5/12). Patients who responded to NAC (n=5) had a better prognosis than non-responders (n=7) (P<0.05).
Conclusions
Extended hepatectomy, including preoperative PVE and multi-step hepatectomy, combined with NAC, may result in a favourable prognosis, especially in patients who respond to NAC, but further studies with more patients are needed to confirm this.
