Debulking hepatectomy for colorectal liver metastasis: Analysis of risk factors for progression free survival
Surgical Oncology(2024)
摘要
Background
The study explores the role of liver debulking surgery in cases of unresectable colorectal liver metastases (CRLM), challenging the traditional notion that surgery is not a valid option in such scenarios.
Materials and methods
Patients with advanced but resectable disease who underwent surgery with a curative intent (Group I) and those with advanced incompletely resectable disease who underwent a “debulking” hepatectomy (Group II) were compared.
Results
There was no difference in the intra-operative and post-operative results between the two groups. The 3-year and 5-year OS rates were 69% and 47% for group 1 vs 64% and 35% for group 2 respectively (p = 0.14). The 3-year and 5-year PFS rates were 32% and 21% for group 1 vs 12% and 8% for group 2 respectively (p = 0.009). Independent predictors of PFS in the debulking group were bilobar metastases (HR = 2.70; p = 0.02); the presence of extrahepatic metastasis (HR = 2.65, p = 0.03) and the presence of more than 9 metastases (HR = 2.37; p = 0.04). Iterative liver surgery for CRLM was a significant protective factor (HR = 0.34, p = 0.04).
Conclusion
An aggressive palliative surgical approach may offer a survival benefit for selected patients with unresectable CRLM, without increasing the morbidity. The decision for surgery should be made on a case-by-case basis.
