Liver metastases

♦ Most secondaries are unsuitable for resection

♦ Benefit to selected patients with colorectal secondaries —33%, 5-year survival

—2%, operative mortality —20%, post-operative morbidity

♦ Better survival if one lobe (compared to two) —if size of secondary <5 cm

—if metachronous resection as opposed to synchronous

♦ A further later liver resection is possible

Treatment options

♦ Cryotherapy

♦ Laser (may have a role but unproven currently)

♦ Radio-frequency ablation

♦ Injection of alcohol
