Surgery for colorectal liver metastases.

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Gastrointestinal Oncology

Background:

• Colorectal liver metastases (CLM) are a significant cause of cancer-related mortality.
• Historically, surgical resection offered cure for a small subset of patients with CLM.
• Advances in understanding and surgical techniques have expanded the potential for curative liver surgery.

Purpose of the Study:

• To review current surgical strategies for colorectal liver metastases.
• To highlight advancements improving patient outcomes and resectability.
• To discuss the role of multidisciplinary management in optimizing surgical candidates.

Main Methods:

• Review of surgical literature and clinical advancements in CLM management.
• Discussion of multidisciplinary team approaches involving chemotherapy and surgical planning.
• Exploration of minimally invasive hepatectomy and pre-operative strategies like portal vein embolization.

Main Results:

• Enhanced understanding and techniques allow more patients to undergo potentially curative liver resection for CLM.
• Multidisciplinary management, including neoadjuvant chemotherapy, increases the number of operable patients and improves outcomes.
• Minimally invasive hepatectomy offers reduced morbidity and shorter hospital stays.
• Portal vein embolization and staged resection enable surgery in previously unresectable cases.

Conclusions:

• Surgical resection of colorectal liver metastases is increasingly effective and offers a curative option for more patients.
• Integration of chemotherapy and advanced surgical techniques, including minimally invasive approaches, is crucial for maximizing resectability and cure rates.
• Multidisciplinary care and innovative preoperative strategies are expanding the possibilities for treating advanced colorectal cancer with liver involvement.
