Abstract:
Objective To evaluate the efficacy and safety of CT-guided percutaneous argon-helium cryoablation in treating hepatic metastases from nasopharyngeal carcinoma. Methods The clinical data of 16 patients with hepatic metastases from nasopharyngeal carcinoma, who had received percutaneous argonhelium cryoablation therapy, were retrospectively analyzed. The quality of life before and after therapy, and the postoperative complications were recorded. After argon-helium cryoablation therapy, the progression-free survival (PFS), the overall survival (OS), and the one-month, 3-month, 6-month, 12-month postoperative tumor local control rates were calculated. Results In all 16 patients, no severe complications occurred and the quality of life was significantly improved after argon-helium cryoablation therapy. The one-month, 3-month, 6-month, 12-month postoperative tumor local control rates were 100％, 87.5％, 80.0％ and 58.3％respectively. The median PFS was 11 months (95％CI: 8.4-13.6 months), and the median survival time was19 months (95％CI: 9.2-28.8 months) . After argon-helium cryoablation therapy, the half-year, one-year and2-year survival rates were 93.8％, 75％ and 43.8％ respectively. Conclusion For the treatment of hepatic metastases from nasopharyngeal carcinoma, CT-guided percutaneous argon-helium cryoablation is minimally-invasive, safe and effective with reliable curative effect.
