Summary
Surgical resection of liver-only metastatic colorectal cancer is a viable option. The number of lesions (four or fewer) and resectability are key factors, not timing or size. Postoperative therapy effectiveness remains under investigation.
Area of Science:
- Hepatobiliary Surgery
- Colorectal Cancer Metastasis
- Surgical Oncology
Background:
- Metastatic colorectal cancer (mCRC) limited to the liver presents unique treatment challenges.
- Resection is a potential therapeutic option for select mCRC patients with liver-only disease.
Purpose of the Study:
- To evaluate the considerations and outcomes for liver resection in patients with metastatic colorectal cancer confined to the liver.
Main Methods:
- Retrospective analysis of patients undergoing laparotomy for liver-only mCRC.
- Assessment of factors influencing surgical decision-making and feasibility.
- Evaluation of resection types and their impact on survival.
Main Results:
- Resection is a consideration regardless of metastasis timing or size.
- Number of lesions (≤4) and surgical feasibility (preserving sufficient liver parenchyma) are critical.
- Various resection types are surgeon-dependent and do not significantly impact survival.
- A significant proportion of patients may not undergo resection due to unexpected extrahepatic disease.
Conclusions:
- Liver resection is a feasible treatment for select patients with liver-only mCRC.
- Surgical planning should prioritize lesion resectability and preservation of liver function.
- The role and efficacy of postoperative adjuvant therapies require further investigation through cooperative trials.
