Percutaneous ultrasound guided radiofrequency and microwave ablation in the treatment of hepatic metastases. A monocentric initial experience
Percutaneous radiofrequency (RFA) and microwave ablation (MWA) are currently the best treatment options forpatients with liver metastases (LM) who cannot undergo a liver resection procedure. Presently, few studies have evaluated theefficacy of tumor ablation in beginner's hands but none at all...

description | Percutaneous radiofrequency (RFA) and microwave ablation (MWA) are currently the best treatment options forpatients with liver metastases (LM) who cannot undergo a liver resection procedure. Presently, few studies have evaluated theefficacy of tumor ablation in beginner's hands but none at all in hepatic metastasis. Our aim was to report the initial experiencewith ultrasound as a tool to guide tumor ablation in a low volume center with no experience in tumor ablation.
We conducted a retrospective cohort study, on a series of 61 patients who had undergone percutaneous US-guided ablations for 82 LM between 2010 and 2015. Long term outcome predictors were assessed using univariate and multivariate analysis.
Complete ablation was achieved in 86.9% of cases (53/61). All MWA sessions (20/20) attained ablation margins >5mm, compared to 79% (49/62) for RFA sessions (p=0.031). Ablation time was significantly shorter for MWA, with a median duration of 10 minutes (range: 6-12) vs. 14 minutes (range: 10-19.5, p=0.003). There was no statistically significant difference in local tumor progression (LTP)-free survival rates between MWA and RFA (p=0.154). On univariate analysis, significant predictors for local recurrence were multiple metastases (p=0.013) and ablation margins |

A larger than 5 mm ablation size is critical for local tumor control. We favor the use of MWA due to its ability to achieve ablation in significantlyshorter times with less incomplete ablations.</description><identifier>ISSN: 1844-4172</identifier><identifier>EISSN: 2066-8643</identifier><identifier>DOI: 10.11152/mu-1957</identifier><identifier>PMID: 31476199</identifier><language>eng</language><publisher>Romania: Romanian Society of Ultrasonography in Medicine and Biology</publisher><subject>Ablation ; Ablation Techniques - methods ; Cancer therapies ; Catheter Ablation - methods ; Chemotherapy ; Cohort Studies ; Colorectal cancer ; Computed tomography ; Electrodes ; Female ; Gallbladder ; Heat sinks ; Humans ; Laboratory tests ; Liver ; Liver - diagnostic imaging ; Liver - surgery ; Liver Neoplasms - diagnostic imaging ; Liver Neoplasms - secondary ; Liver Neoplasms - surgery ; Magnetic resonance imaging ; Male ; Medical imaging ; Metastasis ; Microwaves ; Middle Aged ; Parameter identification ; Patients ; Radio frequency ; Retrospective Studies ; Studies ; Tomography ; Treatment Outcome ; Tumors ; Ultrasonic imaging ; Ultrasonography, Interventional - methods</subject><ispartof>Medical ultrasonography, 2019-08, Vol.21 (3), p.217-224</ispartof><rights>Copyright Romanian Society of Ultrasonography in Medicine and Biology 2019</rights><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c311t-950b5ef8537e3a46a5c0a3215772a7895a09c9b514fd3735c9ed785e7ff102d93</citedby></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/31476199$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Sparchez, Zeno</creatorcontrib><creatorcontrib>Mocan, Tudor</creatorcontrib><creatorcontrib>Hajjar, Nadim All</creatorcontrib><creatorcontrib>Bartos, Adrian</creatorcontrib><creatorcontrib>Hagiu, Claudia</creatorcontrib><creatorcontrib>Matei, Daniela</creatorcontrib><creatorcontrib>Craciun, Rares</creatorcontrib><creatorcontrib>Mocan, Lavinia Patricia</creatorcontrib><creatorcontrib>Sparchez, Mihaela</creatorcontrib><creatorcontrib>Leucuta, Daniel Corneliu</creatorcontrib><title>Percutaneous ultrasound guided radiofrequency and microwave ablation in the treatment of hepatic metastases.
