BACKGROUND: This retrospective study was conducted to assess the safety, efficacy, and long-term results of neoadjuvant chemotherapy and cryotherapy as additional means for eradicating liver metastases from colorectal carcinoma when curative treatment was not possible by resection alone. METHODS: Between January 1996 and December 1997, 131 patients with unresectable liver metastases were referred to our department and received chemotherapy. After 3-6 months of chemotherapy, curative surgery of liver metastases was considered possible in 57 patients, either by resection alone in 33 patients (25%) or cryotherapy associated with resection in 24 patients (18%). Characteristics and survival of patients in the cryotherapy plus resection group were compared with those of the 33 patients in the resection group. RESULTS: All patients in the resection group had partial response to neoadjuvant chemotherapy. In the cryotherapy plus resection group, neoadjuvant chemotherapy resulted in 13 partial responses, 9 stable diseases, and 2 disease progressions. The rate of postoperative complications in the entire series was 14%. No major difference was seen between the two groups. After a median follow-up of 48 months, the median survival time was 39 months. The survival rates at 1, 3, and 4 years were similar in both groups: 94, 58, and 37% in the resection group and 92, 50, and 36% in the cryotherapy plus resection group, respectively. CONCLUSIONS: The combination of neoadjuvant chemotherapy, cryotherapy, and liver resection constitutes a promising treatment strategy for patients with extremely advanced metastatic liver involvement. Patients having more than four liver metastases from a colorectal carcinoma or patients with a poor liver reserve due to previous resection should be screened carefully to determine whether they could be candidates for this procedure.

Abstract

BACKGROUND: This retrospective study was conducted to assess the safety, efficacy, and long-term results of neoadjuvant chemotherapy and cryotherapy as additional means for eradicating liver metastases from colorectal carcinoma when curative treatment was not possible by resection alone. METHODS: Between January 1996 and December 1997, 131 patients with unresectable liver metastases were referred to our department and received chemotherapy. After 3-6 months of chemotherapy, curative surgery of liver metastases was considered possible in 57 patients, either by resection alone in 33 patients (25%) or cryotherapy associated with resection in 24 patients (18%). Characteristics and survival of patients in the cryotherapy plus resection group were compared with those of the 33 patients in the resection group. RESULTS: All patients in the resection group had partial response to neoadjuvant chemotherapy. In the cryotherapy plus resection group, neoadjuvant chemotherapy resulted in 13 partial responses, 9 stable diseases, and 2 disease progressions. The rate of postoperative complications in the entire series was 14%. No major difference was seen between the two groups. After a median follow-up of 48 months, the median survival time was 39 months. The survival rates at 1, 3, and 4 years were similar in both groups: 94, 58, and 37% in the resection group and 92, 50, and 36% in the cryotherapy plus resection group, respectively. CONCLUSIONS: The combination of neoadjuvant chemotherapy, cryotherapy, and liver resection constitutes a promising treatment strategy for patients with extremely advanced metastatic liver involvement. Patients having more than four liver metastases from a colorectal carcinoma or patients with a poor liver reserve due to previous resection should be screened carefully to determine whether they could be candidates for this procedure.
