Objective To explore the clinical value of inflammatory prognostic index combined with dual-source CT perfusion imaging in predicting early response of hepatocellular carcinoma(HCC)after transcatheter hepatic artery chemoembolization(TACE).Methods A total of 25 patients with HCC,who met the inclusion criteria and received initial TACE at the First Affiliated Hospital of Dali University of China from November 2022 to November 2023,were prospectively collected.CT perfusion scan was performed before TACE as well as in 30-40 days after TACE,and blood routine and blood biochemical data were collected.The modified Response Evaluation Criteria in Solid Tumors(mRECIST)was used to evaluate postoperative enhanced CT manifestations.Patients obtaining complete remission(CR)or partial remission(PR)were classified as effective group(n=14),and patients obtaining stable disease(SD)or progression disease(PD)were classified as ineffective group(n=11).The differences in CT perfusion imaging parameters and inflammatory parameters between the two groups were analyzed,and the predictive values of preoperative CT perfusion imaging parameters and inflammatory parameters for postoperative early response of HCC were evaluated.The cutoff value was taken at the maximum Youden index.Univariate analysis and multivariate analysis were used to analyze the effect of CT perfusion imaging parameters,inflammatory parameters and clinical features on the prognosis.The nomogram prediction model was constructed by using R software.Results The post-TACE arterial liver perfusion(ALP),hepatic perfusion index(HPI),blood flow(BF)and blood volume(BV)were significantly lower than their pre-TACE values(all P＜0.05).Afer TACE portal vein perfusion(PVP)was obviously higher than that before operation(P＜0.05).No statistically significant differences in the mean transit time(MTT),flow extraction product(FED),C-reactive protein(CRP),albumin(ALB),neutrophil/lymphocyte ratio(NLR)and inflammatory prognosis index(IPI)existed between the pre-TACE values and post-TACE values(all P＞0.05).The pre-TACE ALP,BF and FED in the effective group were significantly higher than those in the ineffective group,while the pre-TACE CRP and IPI in the effective group were remarkably lower than those in the ineffective group(P＜0.05).There were no statistically significant differences in pre-TACE PVP,HPI,MTT,BV,ALB and NLR between the effective group and the ineffective group before(all P＞0.05).In the effective group,the pre-TACE ALP,HPI,BF,BV and FED were obviously higher than their post-TACE values(all P＜0.05)preoperative PVP was significantly lower than postoperation(P＜0.05),while no statistically significant differences in MTT,CRP,ALB,NLR and IPI existed between the pre-TACE values and the post-TACE values(all P＞0.05).In the ineffective group,the pre-TACE HPI was prominently higher than the post-TACE value(P＜0.05),while no statistically significant differences in ALP,PVP,BF,BV,MTT,FED,ALB,CRP,NLR and IPI existed between the pre-TACE values and the post-TACE values(all P＞0.05).The pre-TACE ALP,BF,BV,FED,CRP and IPI had high predictive values in judging early response of HCC after TACE(all P＜0.05),the AUC values were 0.831,0.779,0.740,0.753,0.779 and 0.805 respectively,and the optimal cutoffs were 33.280 mL/100 mL min,61.860 mL/100 mL min,5.885 mL/100 mL,29.725 mL/100 mL min,30.465 mg/L,1.885 respectively.ALP combined with CRP had the highest predictive value for post-TACE early response of HCC,with an AUC of 0.968(95％CI:0.906-1.000,P＜0.05),ALP combined with IPI could significantly improve the predictive value,with an AUC of 0.961(95％CI:0.894-1.000,P＜0.05),with the sensitivity and specificity being 0.929 and 0.909 respectively.Multivariate analysis showed that pre-TACE ALP and CRP were the independent influencing factors for post-TACE early response of HCC(P＜0.05).The nomogram prediction model constructed based on the pre-TACE ALP and CRP could effectively predict the post-TACE early response of HCC,and the AUC value was 0.968(95％CI:0.908-1.000).Conclusion ALP and CRP can be used to predict the post-TACE early response of HCC,and the combination use of ALP and CRP can significantly improve the predictive value.

A total of 291 patients with genotype-1b chronic hepatitis C (CHC) admitted in Hangzhou Xixi Hospital and Jiande Second People′s Hospital between August 2018 to June 2019. All patients received sofosbuvir/daclatasvir (SOF/DCA) therapy for 12 weeks, and were followed up for 24 weeks after treatment. Data were missed in 2 cases, among remaining 289 cases, there were 238 cases without cirrhosis (non-cirrhosis group), 48 cases with compensated cirrhosis (compensated cirrhosis group) and 5 cases with decompensated cirrhosis (decompensated cirrhosis group). The biochemical indexes, blood routine test results, aspartate aminotransferase-to-platelet ratio index (APRI) , fibrosis-4 (FIB-4) and related adverse event were collected. In non-cirrhotic group, 15 cases and 41 cases were lost follow-up after 12 weeks and 24 weeks of treatment, respectively. The sustained virologic response rate on week 12 (SVR12) and SVR24 in non-cirrhotic group were 82.2% (194/236) and 81.7% (193/236) respectively; whole SVR12 and SVR24 rates in compensated cirrhosis group (48/48) and decompensated cirrhosis group (5/5) were all 100% (χ 2=0.96, χ 2=0.44, P>0.05). The blood ALT [ 14 (6, 23) and 14 (5, 72) U/L], AST[22 (14, 24) and 23 (15, 52) U/L], hemoglobin [46 (42, 48) and 46 (34, 51) g/L], globulin [ (32.6±4.0)和(31.6±3.8) g/L], PLT[ (145.0±49.7) and (142.0±47.4) ×10 9/L], APRI [0.4 (0.2, 0.4) , 0.4 (0.3, 1.5) ] of 289 cases on week 12 and 24 after treatment were significantly improved; compared with baseline values [44(8, 175) U/L, 44(23, 154)U/L, 45 (41, 49) g/L, (33.0±4.0) g/L, (150.0±53.7) ×10 9/L, 0.7(0.3, 6.3)] (Week 12: Z=-14.21, Z=-13.97, Z=-14.72, t=2.00, t=5.22, Z=-13.52; (Week 24: Z=-13.12, Z=-13.04, Z=-4.63, t=7.18, t=7.25, Z=-9.48, all P<0.05). Compared with baseline values [ (16.1±5.4) μmol/L, (5.7±1.5) ×10 9/L, 3.4(1.2, 15.2)], the total bilirubin (15.4±5.8)μmol/L, WBC (6.2±1.8)×10 9/L, FIB-4[3.2 (1.5, 13.7) ] levels were also improved ( t=2.34, t=-5.51, Z=-3.40, all P<0.05). Univariate logistic analysis did not find factors influencing the SVR24 of Sofosbuvir/Daclatasvir therapy. The most common adverse events were fatigue (14.8%,36/248), headache (9.3%,23/248), skin rash and pruritus (4.8%, 12/248), diarrhea (5.6%, 14/248), all of which were alleviated after treatment. In conclusion, SOF/DCA is the optimized selection for na?ve patients with genotype-1b CHC with high SVR12 and SVR24 rate and good safety.
