e15040 Background: The efficacy and safety of radiofrequency ablation (RFA) have been reported in the literatures, which are considered as frontline choice for treatment of liver cancer. Recently, microwave ablation (MWA) has emerged and gained great attention over RFA. However, in comparison to RFA, the safety of MWA for treatment of liver cancer has not been fully reported in the literatures. Studies with large clinical data sets are still needed to understand the technique and avoid the complications. The objective of this study was to retrospectively investigate the common complications of thermal ablations of liver tumors using both RFA and MWA techniques, and compare the safety between these two procedures. Methods: This retrospective study protocol was approved by our institutional ethics committee to allow investigators to review the existing patient’s medical records. A total of 879 patients with hepatic tumors underwent thermal ablation. There were 323 cases having the RFA procedures and 556 cases having MWA procedures. The complications of thermal ablations of liver tumors were compared using both RFA and MWA techniques. Results: A total of 1,030 thermal ablation sessions was performed in 879 patients with a total of 1,652 tumors. There were 323 patients with 562 tumors received a total of 376 RFA with averaged 1.16±0.48 sessions per patient. The other 556 patients with 1,090 tumors received a total of 654 MWA with averaged1.18±0.51 sessions per patient. The mortality rates were 0.31% (1/323) and 0.36% (2/556) in RFA and MWA group. In RFA and MWA group, the major complication rates were 3.5% (13/376) and 3.1% (20/654) (Table 1), meanwhile the minor complication rates were 5.9% (22/376) and 5.7% (37/654). There was no statistical significant difference for the mortality rates, the major complications, the minor complications between the RFA and MWA groups (P>0.05). Conclusions: Thermal ablation therapy in the treatment of liver cancers is relatively safe with low mortality and low incidence of serious complications. The types and incidences of complications caused by RFA and MWA are similar and comparable for safety consideration in clinical settings.

Ablation Success

Thermal ablation (TA) procedures are effective treatments for several kinds of cancers. In the recent years, several medical imaging advancements have improved the use of image-guided TA. Imaging technique plays a pivotal role in improving the ablation success, maximizing pre-procedure planning efficacy, intraprocedural targeting, post-procedure monitoring and assessing the achieved result. Fusion imaging (FI) techniques allow for information integration of different imaging modalities, improving all the ablation procedure steps. FI concedes exploitation of all imaging modalities’ strengths concurrently, eliminating or minimizing every single modality’s weaknesses. Our work aims to give an overview of FI, explain and analyze FI technical aspects and its clinical applications in ablation therapy and interventional oncology.

The Status

The ultrasound (US) imaging technology, including contrast-enhanced US (CEUS) and fusion imaging, has experienced radical improvement, and advancement in technology thus overcoming the problem of poor conspicuous hepatocellular carcinoma (HCC). On CEUS, the presence or absence of enhancement distinguishes the viable portion from the ablative necrotic portion. Using volume data of computed tomography (CT) or magnetic resonance imaging (MRI), fusion imaging enhances the three-dimensional relationship between the liver vasculature and HCC. Therefore, CT/MR-US fusion imaging provides synchronous images of CT/MRI with real-time US, and US-US fusion imaging provides synchronous US images before and after ablation. Moreover, US-US overlay fusion can visualize the ablative margin because it focuses the tumor image onto the ablation zone. Consequently, CEUS and fusion imaging are helpful to identify HCC with little conspicuity, and with more confidence, we can perform ablation therapy. CEUS/fusion imaging guidance has improved the clinical effectiveness of ablation therapy in patients with poor conspicuous HCCs. Therefore; this manuscript reviews the status of CEUS/fusion imaging guidance in ablation therapy of poor conspicuous HCC.
