Abstract
e15649 Background: We report our initial experience with percutaneous cryoablation of HCC in liver. Prior published series are limited. Methods: We treated 30 lesions in 23 patients (pts): Child-Pugh class A, 13 pts; B, 8 pts.; C, 2 pts Candidate pts had residual disease after intra-arterial chemotherapy. Probe placement (2.4 mm, Endocare) occurred under general anesthesia with restricted tidal volume to facilitate computer tomographic (CT) localization. An average 2.7 probes (range 1- 5) achieved an estimated margin of 0.5 cm visualizing the ice ball after two 10 min freeze cycles. Median follow-up was 342 days (range 30–947) Results: Tumors ranged from 1.3 to 5.8 cm. Three pts died within 30 days: 2 following intra-peritoneal hemorrhage despite control of bleeding and 1 from ischemic liver injury following a TIPSS for hydrothorax in a pt with refractory ascites. Two additional pts had hemorrhage with recovery. Risk of bleeding was associated with ascites (P = 0.013). One pt had cutaneous needle tract tumor seeding caused by needle repositioning prior to freezing. Survivors remained clinically stable at the 2–3 month follow-up. At the 2 month evaluation 29 lesions had no residual enhancement by CT. One lesion required a second cryoablation procedure.There were no recurrences in any target lesion (30–947 days). Thirteen pts are alive without recurrence of whom 6 had liver transplant with no (4) or < 5% (2) residual disease. Three pts have had recurrence in non-target liver and have died. Multiple tumors at baseline predicts for hepatic recurrence. Two pts have died from complications of cirrhosis, and 2 are lost to follow-up. Conclusions: Percutaneous cryoablation effectively manages selected hepatic HCC tumors. Cirrhotic pts with ascites have significant risk for hemorrhage. We recommend peri-procedure paracentesis and an immediate post-procedure CT. [Table: see text]
