[Hepatic resection for local recurrence after radiofrequency ablation therapy for colorectal liver metastases].
Patients who underwent hepatic resection of locally recurrent tumors after radiofrequency ablation(RFA)for colorectal liver metastases (CRLM) were retrospectively investigated. Among 12 patients who underwent RFA as first-line treatment for CRLM, 7 experienced local recurrence, 5 of whom (6 nodules) underwent hepatic resection. The mean diameter (range) of the tumors was 9.5(5-16) mm, and they were located at S2, S7 (adjacent to the right hepatic vein), S5/6 (between the root of the anterior and the posterior Glisson's pedicle), S1r (right paracaval portion), S6, and S3. No local recurrence was observed after hepatic resection. In conclusion, hepatic resection must be the initial therapeutic strategy for CRLM, and the indication for RFA must be considered carefully.
