BACKGROUND Vessels encapsulating tumor clusters(VETC)represent a recently discovered vascular pattern associated with novel metastasis mechanisms in hepatocellular carcinoma(HCC).However,it seems that no one have focused on predicting VETC status in small HCC(sHCC).This study aimed to develop a new nomogram for predicting VETC positivity using preoperative clinical data and image features in sHCC(≤3 cm)*** To construct a nomogram that combines preoperative clinical parameters and image features to predict patterns of VETC and evaluate the prognosis of sHCC *** A total of 309 patients with sHCC,who underwent segmental resection and had their VETC status confirmed,were included in the *** patients were recruited from three different hospitals:Hospital 1 contributed 177 patients for the training set,Hospital 2 provided 78 patients for the test set,and Hospital 3 provided 54 patients for the validation *** predictors of VETC were identified through univariate and multivariate logistic *** independent predictors were then used to construct a VETC prediction model for *** model’s performance was evaluated using the area under the curve(AUC),calibration curve,and clinical decision ***,Kaplan-Meier survival analysis was performed to confirm whether the predicted VETC status by the model is associated with early recurrence,just as it is with the actual VETC status and early *** Alpha-fetoprotein_lg10,carbohydrate antigen 199,irregular shape,non-smooth margin,and arterial peritumoral enhancement were identified as independent predictors of *** model incorporating these predictors demonstrated strong predictive *** AUC was 0.811 for the training set,0.800 for the test set,and 0.791 for the validation *** calibration curve indicated that the predicted probability was consistent with the actual VETC status in all three ***,the decision curve analysis demonstr

Esophageal cancer is one of the leading causes of cancer death in the world,with approximately half of the new cases occurring in China every year.^(1)Esophageal squamous cell carcinoma(ESCC)is the main subtype,accounting for more than 90%,and the five-year survival rate is less than 10%.Using large-scale genome analysis,many driver mutations and key pathways associated with ESCC have been ***,these genomic signatures have not improved the clinical management of EscC patients,or established effective targeted therapy.^(2)Esophageal cancer still lacks representative molecular markers.
