Colorectal Cancer Liver Metastases

Abstract

Colorectal cancer is the second leading cause of cancer-related death in the Western world (Siegel et al. CA Cancer J Clin 68:7–30, 2018). One-half of patients with colorectal cancer will eventually develop metastatic disease. A subset of patients with disease localized to the liver are cured with surgical resection. Unfortunately, approximately 60% of patients will develop disease recurrence with nearly two-thirds having disease within the liver (Wei et al. Ann Surg Oncol 13:668–76, 2006; Wicherts et al. Ann Surg 248:994–1005, 2008; Choti et al. Ann Surg 235:759–66, 2002; Nanji et al. Ann Surg Oncol 20:295–304, 2013; House et al. J Am Coll Surgeons 210:744–52, 2010; Abdalla et al. Ann Surg 239:818–25, 2004). Techniques including nonanatomic parenchymal-sparing resections, success in induced hypertrophy of the remnant liver by portal vein embolization (PVE), and two-staged hepatectomy as well as associating liver partition and portal vein ligation (ALPPS) have enabled complete extirpation of colorectal liver metastasis (CRLM) at greater rates. Liver-directed therapy, including local and locoregional strategies, has allowed further treatment of liver lesions in distributions unfavorable for resection. Liver-directed therapy is often used in combination with resection with a goal to treat all visible tumors either by resection or tumor destruction with appropriate margins. Tumor recurrence after “curative” resection is a major problem. The majority of patients will die from recurrent disease, and liver metastases are the commonest cause of death for patients with colorectal cancer (House et al. J Am Coll Surgeons 210:744–52, 2010). Of patients who undergo liver resection, 50–75% will develop disease recurrence within 2 years after resection (Kun-Ming et al. World J Surg Oncol 12:155, 2014; Min-Su et al. Ann Surg Treat Res 87(1):14–21, 2014). Many recurrences are extra-hepatic; thus, adjuvant systemic treatment is standard of care after the management of CRLM.
