MWA has several advantages over RFA, which may make it more attractive than RFA to treat hepatic tumors. However, these techniques have specific advantages and limitations that can make each of them more appropriate than the other one to treat patients with different characteristics.
The benefits of MWA are an improved convection profile, higher constant intratumoral temperatures, faster ablation times, and the ability to use multiple probes to treat multiple lesions simultaneously.

MWA target area size and shape may be more consistent and less dependent on the heat‐sink effect from vascular structures in proximity of the lesion. In studies of RFA versus PEI, the results showed that RFA procedure was connected with significantly higher 2‐year OS rates; however, there were no significant differences in the 1‐year OS rate or incidence of complications.

ARCI Scampia (2005-2006), Napoli (2006-2011) Rendimento carriera . At present, two types of RFA devices are clinically used. Dong et al. Median value of lesion size was 3.2 cm (range, 1–6). According to the literature, the overall survival, local recurrence, complication rates, and mortality in liver metastases patients treated with RFA (vs. MWA) are not statistically different for both the survival times from primary tumor diagnosis and survival times from ablation, between 10% (vs. 6%) and 35.7% (vs. 39.6), between 1.1% (vs. 3.1%) and 24% (vs. 27%), and between 0% (vs. 0%) and 2% (vs. 0.3%).

Twenty‐five patients in the control group died (median follow‐up time was 47.0 ± 12.9 months). Several studies showed that RFA, among all ablative procedures, is to be chosen in patients with HCC smaller than 3 cm, because it reported a complete necrosis frequency of 99% of treated lesions,A 48‐year‐old woman with colorectal liver metastasis on VI hepatic segment treated with radiofrequency ablation. In the scenario of metastatic disease, percutaneous ablation is generally indicated for nonsurgical patients with colorectal cancer metastases isolated to the liver. The major distinction between RFA and MWA heating is that during MWA treatment heat is contained in a volume around the applicator antenna, whereas during RFA, it is restricted to areas of high current density,RFA causes cellular death thanks to thermocoagulation necrosis. Magnetic resonance imaging [,Goldberg et al. We excluded 75 references for the reasons listed in the exclusion criteria. Unlike OS, reported rates of LR after RFA are not univocal ranging. In the 2011–12 season he went on loan to Triestina in Lega Pro Prima Divisione, with whom he played 13 … RFA has become an established treatment modality because of its efficacy, reproducibility, low complication rates, and availability.

They found no significant difference between the two study populations. In HR versus AT, the authors found no significant difference in OS rate at 1‐year; however, there was a significant rise in the HR group in OS rate at 5 years. Also, they showed that the combined group had a better RFS than RFA or MWA. Multivariate analysis identified that recurrence and portal hypertension were associated with OS and that portal hypertension and increased serum α‐fetoprotein were factors significantly associated with DFS.

RFA has been available used in the time and is the more established thermal technique, but lesions with a diameter >2–2.5 cm need multiple overlapping ablations, and subcapsular or high‐risk location of tumors is considered a relative contraindication to RFA. The primary objective was OS.

However, RFA plus TACE were better than RFA alone for the treatment of small HCC,Hung et al. The local recurrence rate was higher after RFA than after HR, which highlights the importance of patient selection, tumor size, vascular abutment, and thorough treatment when using RFA.
