This is a prospective, non-randomized pilot study comparing the cost-utility of hepatic resection, radiofrequency ablation (RFA), systemic chemotherapy, and symptom control only for the treatment of colorectal liver metastases. Seven patients underwent hepatic resection, 7 underwent RFA, 20 received chemotherapy, and 6 received symptom control alone. Liver resection provided an average of 2.51 QALY’s compared to 1.99 QALY’s for RFA, and 1.18 QALY’s for chemotherapy, and 0.82 QALY’s for symptom control alone. The costs were $20,122, $ 15,845, $15,069, and $3,899, respectively. The cost-utilities of liver resection and RFA were similar at $8,027 and $7,965 per QALY, respectively, although patients receiving RFA generally had more advanced disease. The cost-utility of chemotherapy was $12,751/QALY and the cost-utility of symptom control alone was $4,788/QALY. RFA is still a relatively new. However, if long-term survival proves promising, it may prove to be a viable alternative to liver resection.
