Prediction of MSCT imaging manifestations on the detection rate and recurrence of residual lesions after primary hepatocellular carcinoma and its correlation with curative effect
Objective:To analyze the correlation between MSCT imaging performance and the prediction of residual lesion detection rate and recurrence of primary hepatocellular carcinoma(PHCC)after surgery and the curative effect.Methods:A to-tal of 102 patients with PHCC who underwent transcatheter arterial chemoembolization(TACE)in our hospital from August 2019 to December 2022 were selected as research objects.Enhanced MSCT scans were performed on the patients before treatment and half a year after surgery.Angiography examination was performed half a year after the operation.The clinical curative effect of patients was evaluated half a year after the operation.The angiography was regarded as gold standard.Spearman correlation test was used to analyze the correlation between MSCT image performance and curative effect,and the ROC curve was drawn to analyze the effect of MSCT on lesion recurrence predictive value.Results:Compared with the gold standard angiography,MSCT scanning detected 7 cases of postoperative residual lesions,and angiography detected 9 cases.The levels of BV,BF,PS and HAF in patients after treatment were significantly lower than those before treatment,and the difference was statistically significant(P＜0.05).The levels of HAP,HPI and TLP after treatment were significantly lower than those before treatment,and PVP was significantly higher than that of before treatment,and the difference was statistically sig-nificant(P＜0.05).Among these patients,7 cases were significantly effective,64 cases were effective,29 cases were stable,and 2 cases were ineffective.The analysis of patients with different curative effects showed that the levels of BV,BF,PS and HAF in the effective group were significantly lower than those in the ineffective group,and the difference was statistically sig-nificant(P＜0.05).after treatment,the levels of HAP,HPI and TLP in the effective group were significantly lower than those in the ineffective group,and the PVP was significantly higher than that in the ineffective group,and the difference was statisti-cally significant(P＜0.05).BF,BV in the MSCT imaging examination of patients,PS,HAF,HAP,HPI,TLP were significantly negatively correlated with clinical efficacy of patients,and PVP was significantly positively correlated with clinical efficacy of patients(P＜0.05).The sensitivity was 92.77%,and the specificity was 84.21%.The AUC of predicting postoperative recurrence of PHCC by MSCT scanning was 0.853,which has high application value(P＜0.05).Conclusion:MSCT scanning can effectively detect PHCC lesions,and the indicators of MSCT scanning are highly correlated with the clinical efficacy of patients,and MSCT scanning can effectively predict the recurrence of patients after surgery.
