ABSTRACT
Objective:To evaluate the effects of pegylated interferon (Peg-IFN) alfa-2b combined with nucleotide analogues (NAs) on the recurrence of hepatitis B-related liver cancer after resection, and to explore the changes of HBsAg and HBV DNA in patients with chronic hepatitis B liver cancer during postoperative treatment.Methods:The prospective study was conducted. Clinical data of 43 patients with hepatitis B-related liver cancer who underwent radical resection treated in 900th Hospital of People′s Liberation Army were prospectively analyzed from January 2020 to December 2021. Among 43 patients, there were 39 males and 4 females, the age was 30-76 years. According to different treatment methods they were divided into two groups, the patients treated by Peg-IFN alfa-2b combined with NAs were devided into the IFN group( n=10), and those treated by NAs alone into the NAs group( n=33). Two-pair semi-quantitative were collected every 3 months after operation. The recurrence-free survival rate, recurrence time after 2 years in the two groups, the clearance rate and the negative rate of HBsAg and HBV DNA in the two groups. Peg-IFN alfa-2b was evaluated in improving the prognosis of hepatitis B-related liver cancer. The measurement data of normal distribution were expressed by mean±standard deviation ( ± s), and t-test was used for comparison between the two groups. Chi-square test was used for comparison between the two groups of count data. Repeated analysis of measurement variance was used for analysis HBsAg and HBV DNA changes of the interferon group overall survival time and recurrence-free surrival time of patients was estimated using Kaplan-Meier method and the difference between groups was assessed using Log-rank test. Results:HBsAg and HBV DNA: The HBsAg clearance rate at 24 weeks and that at 48 weeks in the IFN group were 24.6% and 59.0% respectively. The HBsAg negative rate at 48 weeks was 16.7%. The HBV DNA clearance rate at 24 weeks and that at 48 weeks were 33.9% and 53.8% respectively. The HBV DNA negative rate was 0 at 48 weeks. The levels of HBsAg and HBV DNA in the IFN group decreased gradually with time. There were statistically differences between the levels of HBsAg and HBV DNA at 0 weeks, 24 weeks and 48 weeks( P<0.05). The 2-year overall survival rates of IFN group and NAs group were 100% and 90.9% respectively. The 2-year recurrence-free survival rates were 90.0% and 63.6% respectively. There were no significant statistical differences in the overall survival rate and recurrence-free survival rate between the groups ( P>0.05). The postoperative recurrence time of the IFN group and the NAs group were (15.00±7.07) months and (5.78±3.39) months respectively. The difference between the two groups was statistically significant ( t=3.160, P<0.01). Conclusion:Long-term antiviral therapy of Peg-IFN alfa-2b combined with NAs can prolong the recurrence time of liver cancer, reduce the levels of HBsAg and HBV DNA in serum, and potentially improve the survival rate of the patients compared with therapy of NAs alone.
ABSTRACT
Objective:To explore the relationship between CD24 expression in preoperative peripheral blood as well as cancer tissue and clinical parameters and prognosis in patients with hepatocellular carcinoma (HCC) after liver transplantation (LT).Methods:From November 2018 to November 2019, clinical data were collected for 65 HCC patients and 41 patients with benign liver disease.The preoperative peripheral blood level of CD24 was detected by enzyme-linked immunosorbent assay (ELISA) and the expression of CD24 in cancerous foci and adjacent tissues examined by immunohistochemistry.Kaplan-Meier survival curves of differential CD24 expression were plotted and survival differences compared by Log-rank method.One-way ANOVA was utilized for examining the relationship between the expression level of CD24 and various clinicopathological parameters and multivariate Cox analysis for screening independent risk factors affecting patient prognosis.Results:The concentration of CD24 in preoperative peripheral blood (p-CD24) of HCC patients (6.51±2.33 μg/L) was significantly higher than that of patients with benign liver disease (4.10±0.91) μg/L, P<0.05.The positive rate of CD24 was obviously higher in cancerous tissues than that in adjacent tissues (87.7% vs. 4.6%, P<0.05). The peripheral blood level of CD24 was positively correlated with the expression intensity of CD24 in tumor tissues (t-CD24, r=0.570, P<0.001). The expression of CD24 (both in blood and cancer foci) was significantly correlated with preoperative level of gamma-glutamyl transferase (GGT), maximal tumor diameter, microvascular invasion, portal vein tumor thrombus, vessel carcinoma embolus and satellite focus ( P<0.05). The expression of CD24 in patients exceeding the Milan/UCSF criteria was higher than those fulfilling the criteria ( P<0.005). Patients with a higher expression of CD24 had worse overall survival and recurrence-free survival rates as compared to those a lower expression of CD24 ( P<0.05). Multivariate Cox analysis indicated that t-CD24 [OS: HR=3.661(1.005-13.333)], P=0.049; recurrence-free survival (RFS): [HR=4.331(1.887-9.942), P=0.001] and preoperative level of alpha fetoprotein (AFP) [OS: HR=4.900(1.590-15.097), P=0.006]; RFS: [HR=3.414(1.614-7.221), P=0.001] were independent risk factors for overall survival and recurrence-free survival in HCC patients undergoing LT. Conclusions:The preoperative peripheral blood level of CD24 in HCC patients undergoing LT indirectly reflects the expression of CD24 in cancerous tissues to a certain extent.And the expression of CD24 in cancerous tissue is one of the independent risk factors affecting OS and RFS of LT patients.
ABSTRACT
Objective:To evaluate the long-term prognosis and recurrence of young liver transplant recipients with hepatocellular carcinoma(HCC).Methods:Based upon the database of liver transplantation center, clinical data were retrospectively reviewed for 39 young recipients(18~40 years)and 158 middle-aged and elderly recipients(over 40 years)from 2013 to 2017. The parameters of overall survival(OS), recurrence-free survival(RFS)and disease-specific survival(DSS)were compared between two groups.Cox's proportional hazard model was utilized for evaluating the prognostic factors.Results:Significant inter-group difference existed in recurrence rate of HCC. Kaplan-Meier analysis revealed no significant difference in OS rate(1/3-year OS, 82.1%, 66.7% and 86.1%, 74.7%, P>0.05)and DSS rate(1/3-year DSS, 94.9%, 82.1% and 99.4%, 91.1%, P=0.053); RFS rate(1/3-year RFS, 51.3%, 41.0% and 73.0%, 62.7%, P=0.008)showed significant differences; Cox multivariate analysis revealed that AFP>400 μg/L was an independent risk factor for OS, DSS and RFS; poorly differentiated tumors and positive micro-vascular invasion(MVI)were independent risk factor for DSS; poorly differentiated tumors and total tumor size >5 cm were independent risk factors for RFS. Conclusions:Although RFS of young adult group is worse than that in middle-aged and elderly group after LT, no significant inter-group difference exists in OS or DSS. And LT is still a quite effective treatment for young HCC patients.
ABSTRACT
Aim To explore the mechanism of Fluspirilene inhibiting HCC through decreasing the expression of Akt.Methods The difference of mRNA was verified by the test of protein expression between Fluspirilenc treatment group and control group by HCC experiment in vivo and vitro, including Western blot, IHC after mRNA array.Results Akt expression was lower in Fluspirilene treatment group than that in control group by mRNA array.Protein expression of Akt, phosphorylate-CDK2 and phos- phorylate-Rb decreased massively in Fluspirilene treatment group in a concentration-dependent manner in HepG2 and Huh7 cells by Western blotting compared with those in control group.Declined expression of phosphorylate-Akt was proved in a concen- tration-dependent manner in xenograft tumor tissues in Fluspirilene treatment group compared with that in control group in IHC test.Conclusions Fluspirilene inhibits HCC by decreasing significantly the protein expression of Akt, phosphorylat-Akt, phos- phorylate-CDK2 and phosphorylate-Rb.

In this report, a known case of renal cell carcinoma, post right nephrectomy patient on treatment with tab sorafenib had developed the hand-foot syndrome
ABSTRACT
Objective To analyze the time-density curve of the small HCCs in the arterial phase and to find out its unique features.Methods All lesions were imaged with single-level serial SCT.The attenuations of the lesion,hepatic artery and hepatic parenchyma were measured.The time-density curve was built with these CT values and their corresponding times.Results The time-density curves of the lesion and liver parenchyma were divided into three kinds:the first kind had two intersects(73%).The first one was seen at the time when the curve of the lesion went up over the one of the parenchyma and the second was seen at the point the curve came down below the parenchyma's.There was no second intersecting point in the second type(19.2%) and the curve of the lesion was below that of the parenchyma in the third (7.7%). Conclusion The initial time of the enhancement of small SHCC is (21.6?6) s.The optimal time of the enhancement of SHCC is (36?8) s.
ABSTRACT
Objective:To study the expression of COX-2 and Survivin in HCC tissues and their relationship for supplying experimental evidence for gene diagnosis and treatment of HCC.Methods:The expression of COX-2 and Survivin was detected in 30 cases of hepatocellular carcinoma and 10 normal liver tissue by Flow cytometry (FCM) and immunohistochemistry (SP).Results:Two experimental methods showed that the positive expression of COX-2 and Survivin in HCC was significanly higher than that in normal liver tissue and there was significanly positive correlation between the expression of COX-2 and Survivin.Conclusion:The hyper-expression of COX-2 and Survivin in tissue can reflex the biological behavior of HCC and there are synergistic effect between them during the development of HCC.A possible mechanism is inhibition of tumor cell apoptosis through upregulating Survivin by COX-2,and promoting abnormal cell proliferation in development of hepatocellular carcinoma.
