Hepatic Metastasis from Colorectal Cancer

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Gastroenterology

Background:

• The liver is the most frequent site for colorectal cancer metastasis due to its portal circulation.
• Colorectal cancer metastasis is present in 14-18% of initial consultations and 10-25% at primary tumor resection, increasing to 35% with CT scans.
• Despite improved life expectancy, metastasis, recurrence, and advanced tumors remain poor prognostic factors.

Purpose of the Study:

• To review predisposing factors, diagnostic methods, and treatment strategies for hepatic metastasis from colorectal cancer.
• To emphasize the importance of early diagnosis and adequate treatment for improved patient outcomes.
• To highlight the role of modern surgical approaches in managing liver-confined colorectal metastasis.

Main Methods:

• Review of existing literature on colorectal cancer liver metastasis.
• Analysis of diagnostic modalities, including computed tomography (CT) scans.
• Evaluation of surgical interventions, specifically hepatectomy, and their outcomes.

Main Results:

• Hepatic metastasis significantly impacts survival, with median survival <8 months without treatment.
• Approximately 20-30% of patients have liver-confined disease amenable to surgery.
• Hepatectomy, even up to 70% of the liver, can be performed with <5% mortality in specialized centers.

Conclusions:

• Knowledge of predisposing factors, diagnostics, and treatments for liver metastasis is crucial.
• Efficient screening programs for early diagnosis and timely treatment are vital.
• Modern surgical strategies offer improved survival for select patients with colorectal cancer liver metastasis.
