Hepatectomy for metastatic liver tumor

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Gastrointestinal Oncology

Background:

• Liver metastasis is a common complication of colorectal cancer and other malignancies.
• Hepatectomy is a potential curative treatment for liver metastases.
• Predicting outcomes after hepatectomy for liver metastases remains challenging.

Purpose of the Study:

• To evaluate the outcomes of hepatectomy for liver metastases.
• To identify prognostic factors influencing survival after hepatectomy for liver metastases.

Main Methods:

• Retrospective analysis of 77 patients who underwent hepatectomy for liver metastasis at the National Cancer Center Hospital.
• Classification of metastasis based on unilobular (H1), bilobular (H2), and disseminated (H3) patterns.
• Subgroup analysis of H1 metastasis into solitary and multiple lesions.

Main Results:

• The operative mortality rate was 3.9%.
• The overall 5-year survival rate was 26.7%.
• Unilobular metastasis (H1) showed better survival than bilobular (H2) and disseminated (H3) metastasis.
• Solitary unilobular metastasis had a better prognosis than multiple unilobular metastasis.
• Survival for multiple unilobular metastasis was similar to H2 and H3 metastasis.

Conclusions:

• Hepatectomy is a feasible treatment for liver metastasis with acceptable operative mortality.
• The extent and pattern of liver metastasis significantly influence long-term survival.
• The solitary nature of metastasis is a crucial positive prognostic factor after hepatectomy.
