AbstractBackgroundThe aim of the study was to assess the primary efficacy of robot-assisted microwave ablation and compare it to manually guided microwave ablation for percutaneous ablation of liver malignancies.Patients and methodsWe performed a retrospective single center evaluation of microwave ablations of 368 liver tumors in 192 patients (36 female, 156 male, mean age 63 years). One hundred and nineteen ablations were performed between 08/2011 and 03/2014 with manual guidance, whereas 249 ablations were performed between 04/2014 and 11/2018 using robotic guidance. A 6-week follow-up (ultrasound, computed tomography and magnetic resonance imaging) was performed on all patients.ResultsThe primary technique efficacy outcome of the group treated by robotic guidance was significantly higher than that of the manually guided group (88% vs. 76%; p = 0.013). Multiple logistic regression analysis indicated that a small tumor size (≤ 3 cm) and robotic guidance were significant favorable prognostic factors for complete ablation.ConclusionsIn addition to a small tumor size, robotic navigation was a major positive prognostic factor for primary technique efficacy.

272 Background: Percutaneous ablation and transarterial chemo- or radioembolization are commonly used in the treatment of HCC and mCRC to the liver. IRE using the Nanoknif is more versatile than other ablative modalities (such as RFA) in that tumors abutting vascular structures can be treated with IRE without compromise of the vessels or concern for the heat sink effect of nearby blood flow. Methods: We examined the records of patients (pts) referred for IRE for HCC and mCRC. The procedures were all done percutaneously under general anesthesia using a standard protocol. The primary endpoint was progression-free survival (PFS). Responses were assessed using the modified RECIST criteria. Results: Between 1/2010 and 8/2011, 49 pts underwent percutaneous ablation of unresectable HCC and mCRC liver tumors using IRE – 33 with HCC and 16 with mCRC. A total of 76 lesions were treated in 62 sessions; the median number of lesions treated per patient was 1 (range 1-4) and the median tumor size treated was 2.1cm (range 0.8-6). After IRE, 20 pts (41%) had a complete response (CR), 19 (39%) had a partial response and 10 (20%) had stable disease as their best response. The Kaplan-Meier estimated median PFS was 11.3 months (95% CI 9.6-12.9) for all pts, 11.6 months (95% CI 10.2-12.9) for HCC pts, and 10.4 months (95% CI 5.4-15.4) for mCRC patients. The one-year PFS was significantly higher for pts achieving a CR compared to those who did not achieve a CR (75% versus 59%, log rank p = 0.05). The number of liver lesions at baseline and size of the treated lesions were not associated with any differences in survival. The IRE was complicated in 6 pts (12%) by pneumothorax (2), pleural effusion (2), and atrial flutter/fibrillation during anesthesia (2). All pts recovered fully from these complications. One pt died within 1 month of the IRE due to disease progression. Conclusions: IRE of liver tumors is safe. The PFS rates for pretreated mCRC and unresectable HCC are promising. A complete lack of enhancement of the treated lesion on the post-IRE CT scan appears to be associated with longer survival.

Abstract Background To compare the frequency of adverse events of thermal microwave (MWA) and radiofrequency ablation (RFA) with non-thermal irreversible electroporation (IRE) in percutaneous ablation of hepatocellular carcinoma (HCC). Patients and methods We retrospectively analyzed 117 MWA/RFA and 47 IRE procedures (one tumor treated per procedure; 144 men and 20 women; median age, 66 years) regarding adverse events, duration of hospital and intensive care unit (ICU) stays and occurrence of a post-ablation syndrome. Complications were classified according to the Clavien & Dindo classification system. Results 70.1% of the RFA/MWA and 63.8% of the IRE procedures were performed without complications. Grade I and II complications (any deviation from the normal postinterventional course, e.g., analgesics) occurred in 26.5% (31/117) of MWA/RFA and 34.0% (16/47) of IRE procedures. Grade III and IV (major) complications occurred in 2.6% (3/117) of MWA/RFA and 2.1% (1/47) of IRE procedures. There was no significant difference in the frequency of complications (p = 0.864), duration of hospital and ICU stay and the occurrence of a post-ablation syndrome between the two groups. Conclusions Our results suggest that thermal (MWA and RFA) and non-thermal IRE ablation of malignant liver tumors have comparable complication rates despite the higher number of punctures and the lack of track cauterization in IRE.
