Local treatment options for colorectal cancer patients with liver oligometastases: a literature review

Liver metastases is the most common type of colorectal cancer progression. Patients who have undergone surgical resection of liver metastases and received systemic antineoplastic therapy demonstrate the highest survival rates. Recognizing the oligometastatic disease as an individual entity has allowed identification of patients with advanced cancer who may benefit the most from the use of local treatment options. There are several methods of local treatment that can be currently used for the treatment of liver metastases: surgical resection, stereotactic radiation therapy, radiofrequency or microwave ablation, irreversible electroporation, and cryodestruction. The aim of our review is to provide a comparative assessment of the effectiveness, advantages and disadvantages of these techniques.
