Summary
Repeat liver surgery for colorectal cancer recurrence offers survival benefits when tumors are fully removable. However, outcomes are limited by factors like lymph node metastasis and extrahepatic disease.
Area of Science:
- Surgical Oncology
- Hepatobiliary Surgery
- Colorectal Cancer Research
Background:
- Recurrent colorectal cancer (CRC) in the liver presents significant treatment challenges.
- Surgical resection is a potential curative option for liver metastases.
- Identifying prognostic factors is crucial for patient selection in repeat liver surgery.
Purpose of the Study:
- To evaluate the efficacy of repeat hepatectomy for liver recurrence of colorectal cancer.
- To identify prognostic indicators for improved patient selection and outcomes after repeat liver surgery.
Main Methods:
- Retrospective analysis of data from 90 repeat hepatectomies for recurrent CRC.
- Data included second (n=75), third (n=12), and fourth (n=3) liver resections.
- Survival rates and recurrence-free survival were analyzed.
Main Results:
- Three- and 5-year survival rates after second hepatectomy were 48% and 31%.
- 27% of patients remained recurrence-free after a median follow-up of 27 months.
- Independent poor prognostic factors included: ≥4 tumors, positive lymph nodes, extrahepatic disease, and residual tumor.
Conclusions:
- Repeat hepatectomy is a viable option for resectable liver recurrence of CRC.
- Careful patient selection is essential, considering prognostic factors.
- Benefit is limited in patients with lymph node metastases, multiple tumors, or extrahepatic disease.
