Summary
Hepatic resection is a key treatment for colorectal liver metastases. This study found it safe and effective in selected patients, with a 30.5% 5-year survival rate, especially for metachronous metastases.
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Gastroenterology
Background:
- Colorectal liver metastases lack effective treatments, making hepatic resection a primary consideration.
- Surgical intervention is crucial for managing liver metastases from colorectal cancer.
Purpose of the Study:
- To evaluate the safety and efficacy of hepatic resection for colorectal liver metastases.
- To identify factors influencing survival outcomes after hepatic resection.
Main Methods:
- Retrospective review of 26 selected patients who underwent hepatic resection for liver metastases between 1980 and 1990.
- Data collected included patient demographics, tumor characteristics, resection type, and preoperative CEA levels.
- Survival rates and recurrence patterns were analyzed.
Main Results:
- Complete tumor removal with negative margins was achieved in 24 patients.
- The 5-year survival rate was 30.5%. Metachronous metastases had a better survival rate (46.6%) than synchronous metastases (13.6%).
- No perioperative mortality occurred; morbidity was 66.6% (mostly minor). Recurrence was observed in 60% of patients, primarily in the liver.
Conclusions:
- Hepatic resection is a safe and viable option for selected patients with colorectal liver metastases.
- The timing of metastasis (metachronous vs. synchronous) significantly impacts survival outcomes.
- Further research into optimizing surgical strategies for liver metastases is warranted.
