Introduction: Radical liver resection is the only method for the treatment of patients with colorectal liver metastases (CLM); however, only 20–30% of patients with CLMs can be radically treated. Radiofrequency ablation (RFA) is one of the possible methods of palliative treatment in such patients. Methods: RFA was performed in 381 patients with CLMs between 01 Jan 2001 and 31 Dec 2018. The mean age of the patients was 65.2±8.7 years. The male to female ratio was 2:1. Open laparotomy was done in 238 (62.5%) patients and the CT-navigated transcutaneous approach was used in 143 (37.5%) patients. CLMs <5 cm (usually <3 cm) in diameter were the indication for RFA. We used RFA as the only method in 334 (87.6%) patients; RFA in combination with resection was used in 36 (9.4%), and with multi-stage resection in 11 (3%) patients. We performed RFA in a solitary CLM in 170 (44.6%) patients, and in 2−5 CLMs in 211 (55.6%) patients. We performed computed tomography in each patient 48 hours after procedure. Results: The 30-day postoperative mortality was zero. Complications were present in 4.8% of transcutaneous and in 14.2% of open procedures, respectively, in the 30-day postoperative period. One-, 3-, 5- and 10-year overall survival rates were 94.8, 66.8, 43.9 and 16.6%, respectively, in patients undergoing RFA, and 90.6, 69.1, 52.8 and 39.2%, respectively, in patients with liver resections. Disease free survival was 63.2, 30.1, 18.4 and 13.1%, respectively, in the same patients after RFA, and 71.1, 33.3, 22.8 and 15.5%, respectively, after liver resections. Conclusion: RFA is a palliative thermal ablation method, which is one of therapeutic options in patients with radically non-resectable CLMs. RFA is useful especially in a non-resectable, or resectable (but for the price of large liver resection) solitary CLM <3 cm in diameter and in CLM relapses. RFA is also part of multi-stage liver procedures.

637 Background: Hepatic resection is the mainstay of management for colorectal liver metastases. But, the treatment for colorectal liver metastases requires a multidisciplinary therapeutic strategy. The aim of this study was to compare recurrence and survival rates for patients treated with hepatic resection or radiofrequency ablation (RFA) for colorectal liver metastases. Methods: Between July 2002 and September 2010, 52 patients underwent hepatic resection and 58 underwent RFA for synchronous or metachronous colorectal liver metastases. A retrospective analysis was performed. Patients with extrahepatic metastases were excluded. Results: The two groups had similar mean age, comorbid medical conditions, primary disease stage, and number of tumors. Preoperative median serum carcinoembryonic antigen (CEA) level was significantly higher in the resection group (13.8 ng/mL vs. 3.1 ng/mL; p = 0.001). Median diameter of main tumors was significantly greater in resection group (4.1 cm vs. 2.0 cm; p = 0.002). Recurrence rate after treatment was 46.2% (24/52) in the resection group and 70.7% (41/58) in the RFA group. Marginal recurrence after resection or RFA was observed in 7.6% (4/52) and 46.6% (27/58), respectively (p = 0.003). Median recurrence free survival (28.0 vs. 12.0 months; p = 0.007) and median overall survival (43.0 vs. 26.0 months; p = 0.023) were significantly longer in the resection group. Conclusions: Hepatic resection is the treatment of choice for colorectal liver metastases. RFA for colorectal liver metastases was associated with higher marginal recurrence rate and shorter recurrence free and overall survival.

Purpose: This phase II/III, non-randomized clinical trial aimed to determine the efficacy and safety of the combination of radiofrequency ablation (RFA) and cytokine-induced killer (CIK) cells transfusion for patients with colorectal liver metastases (CRLMs). Experimental Design: A total of 60 eligible patients with CRLMs were enrolled and divided into Group A (RFA alone, n = 30) and Group B (RFA plus CIK, n = 30), and following enzyme-linked immunosorbent spot assay was performed in 8 patients with CEA > 50 ng/mL pre-RFA and 7 days post-RFA and CIK treatment, respectively. Results: The median progression-free survival (PFS) times of Group A and Group B were 18.5 months and 23 months, respectively (P = 0.0336). The 3-year progression-free rates were 13.3% in Group A and 20.3% in Group B, respectively. The median overall survival time was 43 months in Group A, and not reached in Group B. The 3-year survival rates were 64.6% in Group A and 81.0% in Group B, respectively (P = 0.1187). Among the 8 patients with CEA > 50ng/mL, 6 had increase of circulating CEA-specific T cells after RFA (P = 0.010). After CIK cell therapy, the number of CEA-specific T cells increased in all the 8 patients comparing with that pre-treatment (P = 0.001) and in 7 patients comparing with that post-RFA (P = 0.028). Conclusions: We firstly confirm that the combination of RFA and CIK cells boosts CEA-specific T cell response and shows to be an efficacious and safe treatment modality for patients with CRLMs.
