Despite efforts in screening programs, early diagnosis of HCC remains challenging (<a class="elsevierStyleCrossRef" href="#bib3">3</a>). Although surgical resection and transplant are the most effective curative treatment for HCC, they are not a feasible option for the majority of patients (<a class="elsevierStyleCrossRef" href="#bib4">4</a>). In this context, several loco-regional therapies such as radiofrequency ablation (RFA) have received increasing attention as a therapeutic option for patients who are not eligible to undergo surgical resection or transplant, or as a bridging or downsizing modality before definitive treatment (<a class="elsevierStyleCrossRef" href="#bib5">5</a>,<a class="elsevierStyleCrossRef" href="#bib6">6</a>).</p><p id="para20" class="elsevierStylePara elsevierViewall">RFA consists of an alternating electric current that is applied to the nodule using an electrode needle.

Radiomics has the potential to detect specific characteristics of imaging that cannot be assessed visually. We hypothesize that MRI-based radiomic analysis of HCC may assist in predicting which patients will present sustained complete response after RFA. Awareness of the likely pattern of treatment response before RFA could improve the management of the patient with HCC by providing personalized treatment, and thus avoiding unnecessary procedures, reducing costs and optimizing available resources (<a class="elsevierStyleCrossRef" href="#bib22">22</a>).

Firstly, SBF, which reflect volume, size and geometry properties of the tumor had low discriminatory performance. This result runs against current medical practice since size is one of the most common criteria used to guide the treatment of HCC (<a class="elsevierStyleCrossRef" href="#bib32">32</a>,<a class="elsevierStyleCrossRef" href="#bib33">33</a>). Thus, our findings may reflect the complexity of HCC and suggest that size alone should not be used as the only criterion to determine the treatment of HCC.</p><p id="para190" class="elsevierStylePara elsevierViewall">Additionally, considering that FOF describe the distribution of the grayscale values, without taking into account the interaction of the pixels with their neighborhood, while SOF are determined by the relationship between the pixels and their neighborhood, the latter is able to provide better information regarding intra-tumoral heterogeneity (<a class="elsevierStyleCrossRef" href="#bib24">24</a>). Indeed, tumor heterogeneity had a higher discriminatory performance in predicting sustained complete response, particularly the following features: Dependence Non-Uniformity Normalized, Dependence Variance and Maximum Probability. Again, counterintuitively, the current findings indicate that patients with sustained complete response had greater nodule heterogeneity (e.g. Dependence Non-Uniformity Normalized) compared to those with recurrence. Considering that in early hepatocarcinogenesis, HCC arises from a dysplastic nodule, and that smaller HCCs are selected to treat with RFA (<a class="elsevierStyleCrossRef" href="#bib33">33</a>,<a class="elsevierStyleCrossRef" href="#bib34">34</a>), we hypothesize that textural analysis may have demonstrated subtle heterogeneity patterns in nodules in their early phases of dedifferentiation, which may explain the higher sustained complete response among heterogeneous nodules. However, this conclusion is limited due to the retrospective nature of the study, the absence of histological correlation and the small sample size.</p><p id="para200" class="elsevierStylePara elsevierViewall">Currently, a multidisciplinary team is required to choose RFA based on rather limited information to predict suitability for RFA. Therefore, there may be a large clinical impact if the team was able to use radiomic feature information to guide their decision. Knowledge of the predicted response using radiomic features may influence the treatment decisions of the multidisciplinary team, such as whether to recommend RFA or whether to change the patients' priorities on the liver transplant list, thereby allowing a more personalized treatment and improving the cost-effectiveness of HCC treatment.</p><p id="para210" class="elsevierStylePara elsevierViewall">The most important limitation in this study was the small sample size, in part due to the rigidity of our inclusion and exclusion criteria, which were set in order to achieve a more homogeneous group of patients. It was not possible to produce a statistical model to include the clinical data. Patients with sustained complete response were predominantly female and had more normal results of INR, albumin, and total bilirubin, which may be correlated with better liver function, and consequently improved treatment response or reduced tumorigenic potential. Larger studies are necessary to overcome these limitations and provide a better generalization of our results, possibly including clinical and laboratorial data in the prediction model and investigation of the independence of the statistical variables.</p></span><span id="cesec160" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="cestitle210">CONCLUSION</span><p id="para220" class="elsevierStylePara elsevierViewall">This pilot study demonstrates that radiomics in pre-treatment MRI might be used to identify patients with HCC who are more likely to have a sustained complete response to RFA.
