摘 要:Objective and Impact *** study developed and validated a deep semantic segmentation feature-based radiomics(DSFR)model based on preoperative contrast-enhanced computed tomography(CECT)combined with clinical information to predict early recurrence(ER)of single hepatocellular carcinoma(HCC)after curative *** prediction is of great significance to the therapeutic decision-making and surveillance strategy of *** prediction is important for ***,it cannot currently be adequately ***,208 patients with single HCC after curative resection were retrospectively recruited into a model-development cohort(n=180)and an independent validation cohort(n=28).DSFR models based on different CT phases were *** optimal DSFR model was incorporated with clinical information to establish a DSFR-C *** integrated nomogram based on the Cox regression was *** DSFR signature was used to stratify high-and low-risk ER ***.A portal phase-based DSFR model was selected as the optimal model(area under receiver operating characteristic curve(AUC):development cohort,0.740;validation cohort,0.717).The DSFR-C model achieved AUCs of 0.782 and 0.744 in the development and validation cohorts,*** the development and validation cohorts,the integrated nomogram achieved C-index of 0.748 and 0.741 and time-dependent AUCs of 0.823 and 0.822,respectively,for recurrence-free survival(RFS)*** RFS difference between the risk groups was statistically significant(P0.0001 and P=0.045 in the development and validation cohorts,respectively).***-based DSFR can predict ER in single HCC after curative resection,and its combination with clinical information further improved the performance for ER prediction.
