Hypothesis
What is the appropriate surgical treatment for liver metastases from colorectal cancers?
Conclusion
Non-anatomic limited resection may be a viable approach for colorectal liver metastases, but adequate margins are still recommended.
Supporting Evidence
- Major hepatic resection is the usual procedure for treatment of hepatic metastases from colorectal cancers.
- Reported series of surgical resection for hepatic metastases from colorectal carcinoma with intent to cure demonstrate a 5 year survival rate of 30-40%.
- Positive surgical margins were identified in 20% of patients.
Takeaway
Doctors are studying how to remove liver tumors from colon cancer safely, and they found that sometimes they can take out less liver tissue than previously thought.
Methodology
Forty consecutive patients who underwent hepatic resections were prospectively studied, for a total of 89 metastatic liver tumors.
Potential Biases
The authors' conclusions may be biased due to the small sample size and lack of follow-up data.
Limitations
The study's findings need to be validated with larger patient numbers and long-term follow-up.
Participant Demographics
Patients undergoing hepatic resections for colorectal cancer metastases.
