Abstract
Background
Although correlation of postoperative morbidity with long-term survival is recognized to influence long-term survival after other cancer surgery, little information exists about the impact of postoperative morbidity on patient outcomes following liver resection for colorectal metastases.
Methods
We studied the impact of postoperative morbidity on long-term survival after liver resection for colorectal cancer metastases using data from 312 patients with curative hepatectomy.
Results
Among all 312 patients evaluated, 98 complications occurred, affecting 80 patients (26%). The 80 patients with morbidity had a lower disease-free rate (P = 0.03), resulting in poor overall survival (P = 0.02) compared with the group with no morbidity (n = 232). Decreases in disease-free and overall survival also were associated with severity of postoperative complications. When patients were divided according to extent of metastases, little impact of morbidity on overall survival (P = 0.10) and disease-free rate (P = 0.35) was demonstrated in patients whose metastases were less advanced. However, a negative impact of morbidity compared with no morbidity on disease-free rate (P < 0.01) and overall survival (P < 0.01) was confirmed in patients with aggressive or advanced metastases.
Conclusions
Postoperative morbidity had a negative impact on long-term survival, especially for aggressive or advanced metastases or severe complications.
