Material and methods: A retrospective analysis was conducted on patients diagnosed with hepatocellular carcinoma (HCC) confirmed by pathology results from October 2016 to December 2023. Patients were categorized into DPHCC and non-DPHCC (NDPHCC) groups based on immunohistochemical findings. Clinical baseline characteristics and ultrasound features were compared between these groups. Multivariable logistic regression was employed to identify predictive factors. A logisticregression model and nomogram were developed to predict DPHCC.Results: This study included 219 HCC patients (average age: 55.84±9.00, 173 males), with 61 cases of DPHCC and 158 cases of NDPHCC. The results of multivariate logistic regression indicated that halo sign (OR=1.93, p=0.049), PVP hypo-enhancement (OR=2.73, p=0.002) and nodule-in-nodule sign (OR=4.23, p=0.003) were independent predictors of DPHCC. The model's AUC value was 0.73 (95%CI: 0.65-0.80). The calibration curve displayed good predictive accuracy.Conclusions: Ultrasound features, including CEUS, may provide additional information for the non-invasive diagnosis of DPHCC.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142869814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis was done on the quantitative parameters from RT and BPE found by CEUS.Results: Complete ablation was obtained in 89.1% of lesions. When compared to BPE, RT had significantly greater peak intensity (PI), time to peak (TTP), area under the curve (AUC), ratio of PI and base intensity (PI/BI), and enhanced intensity (EI) values (all p<0.05). PI, TTP, AUC, PI/BI, and EI had large areas under the receiver operating (ROC) curves. A binary logistic regression analysis, respectively, demonstrated that PI and PI/BI were independent favorable prognostic variables.Conclusions: Multiple parameters of quantitative analysis of CEUS can aid in distinguishing immediately between RT and BPE lesions. PI and PI/BI may be a more promising parameter. Immediate CEUS evaluation following RFA may allow immediate retreatment of RT during the same operation time, which reduces patients' hospital stays and financial costs.","PeriodicalId":94138,"journal":{"name":"Medical ultrasonography","volume":" ","pages":"339-347"},"PeriodicalIF":0.0,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141857507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we aimed to establish a nomogram based on ultrasound features for predicting CLNM in PTMC.Material and methods: This retrospective study included 636 patients with PTMC, in which the CLNM status was pathologically confirmed. Univariate and multivariate regression analyses were conducted to screen for risk factors associated with CLNM. Then, a CLNM prediction model was established, receiver operating characteristic, calibration, and decision curve analyses were used to assess the model's performance.Results: Five variables, including age, sex, combined CLNM status, tumor size, and capsule invasion, were included in the nomogram. The values of the area under the receiver operating characteristic curve in the training and validation datasets were 0.720 (95% confidence interval [CI], 0.649-0.791) and 0.704 (95% CI, 0.622-0.786), respectively.Conclusions: An ultrasound-based nomogram was successfully established, of which the predictive model shows excellent predictive performance and can be used to evaluate the status of CLNM in PTMC.
