Background
The aim of this study was to analyze the outcome of patients that received neoadjuvant chemotherapy prior to resection for colorectal liver metastases (CRLM) and compare them with a matched cohort of patients that underwent resection followed by adjuvant chemotherapy.
Methods
687 patients have undergone curative resection between January 1993 and January 2006. In this period, 84 patients received neo-adjuvant chemotherapy and 71 of this group went on to resection. A control group was chosen, matched with these patients, made up of patients who underwent resection followed by adjuvant chemotherapy.
Results
There was no difference in clinico-pathological features between the neoadjuvant and the control group. However patients in the control group had more-extended resections and longer hospital stays than those in the neoadjuvant group (p = 0.015). Patients in the control group had an increased incidence of early recurrences (p < 0.001). Despite this, there was no significant difference in either the cancer-specific or the disease-free survival between the two groups of patients.
Conclusion
Neoadjuvant chemotherapy has a role in the management of patients with disease that is considered initially unresectable as a down-sizing technique. In patients with resectable disease, the test-of-time approach that neoadjuvant therapy offers is yet to be proven.
