ABSTRACT
ObjectiveTo investigate the efficacy and safety of 125I intraluminal irradiation combined with lenvatinib in the treatment of progressive extrahepatic cholangiocarcinoma. MethodsA retrospective analysis was performed for 25 patients with progressive extrahepatic cholangiocarcinoma who attended Department of Interventional Radiology， The First Affiliated Hospital of Zhengzhou University， from January 2018 to November 2021， and according to the treatment modality， they were divided into combination group with 13 patients （125I intraluminal irradiation combined with lenvatinib） and control group （125I intraluminal irradiation alone）. The two groups were compared in terms of technical success rates， changes in liver function， stent patency， survival time， and incidence rates of adverse events. The independent－samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank－sum test was used for comparison of continuous data with skewed distribution between two groups； the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan－Meier method and the log－rank test were used to evaluate survival time and stent patency. ResultsAll patients had successful implantation of biliary stents and 125I particles， with a technical success rate of 100%. After 1 month of treatment， both groups had significant improvements in the serum levels of total bilirubin， direct bilirubin， alanine aminotransferase， and aspartate aminotransferase （all P<0.05）. There were significant differences between the control group and the combination group in the duration of stent patency （7.0 months vs 9.5 months， P=0.022） and median survival time （11.5 months vs 15.6 months， P=0.008）. There were no intolerable adverse events in the combination group during treatment. ConclusionCompared with 125I intraluminal irradiation alone， 125I intraluminal irradiation combined with lenvatinib has better efficacy and is a safe and effective treatment regimen for progressive extrahepatic cholangiocarcinoma.
ABSTRACT
Objective To investigate the safety and efficacy of camrelizumab added to second-line therapy after drug- eluting bead transarterial chemoembolization (DTACE) combined with apatinib for unresectable hepatocellular carcinoma (HCC). Methods A retrospective analysis was performed for 89 HCC patients with camrelizumab added to second-line therapy who attended The First Affiliated Hospital of Zhengzhou University from December 2019 to December 2020. The primary endpoints were overall survival (OS) and progression-free survival (PFS) after the application of camrelizumab, and the secondary endpoints were objective remission rate (ORR), disease control rate (DCR), and treatment-related adverse events (TRAEs). The Kaplan-Meier method was used to plot survival curves, the Log-rank test was used for stratified analysis of subgroups based on baseline characteristics, and the influencing factors for prognosis were analyzed. Results A total of 89 patients were screened and followed up in this study. The patients were followed up to December 2021, with a median follow-up time of 16 months, a median OS time of 17.0 (95% confidence interval [ CI ]: 15.3-18.7) months, and a median PFS time of 7.0 (95% CI : 6.2-7.8) months. There were significant differences in OS and PFS between the patients with different ECOG-PS scores, liver function Child-Pugh classes, portal vein invasion, patterns of progression, times of DTACE treatment, durations of oral administration of apatinib, and durations of application of camrelizumab (all P 4 months had significant improvements in median OS [21.0 (95% CI : 19.1-22.9) months vs 14.0 (95% CI : 10.4-17.6) months, χ 2 =19.399, P 5 months had significant improvements in median OS [22.0 (95% CI : 20.2-23.8) months vs 13.0 (95% CI : 9.3-16.7) months, χ 2 =22.336, P < 0.001] and PFS [9.0 (95% CI : 7.0-11.0) months vs 5.0 (95% CI : 4.1-5.9) months, χ 2 =26.141, P < 0.001]. Post-embolization syndrome was the adverse event after DTACE and resolved after symptomatic treatment. Adverse reactions related to targeted drugs and immunotherapy all resolved after symptomatic supportive treatment, with no grade ≥4 adverse reactions, and no patients withdrew from target-free therapy due to TRAEs. Conclusion As for DTACE combined with apatinib in the treatment of unresectable HCC, camrelizumab added after progression has a marked therapeutic efficacy with safe and controllable TRAEs.
ABSTRACT
Objective To investigate the cost-effect of transarterial chemoembolization (TACE) with CalliSpheres beads loaded with arsenic trioxide (ATO) (CBATO) versus ATO iodized oil emulsion (conventional TACE, cTACE) in the treatment of unresectable liver cancer. Methods A total of 100 patients with advanced liver cancer who attended The First Affiliated Hospital of Zhengzhou University from May 2017 to December 2018 were enrolled and divided into CBATO group( n =45) and cTACE group( n =55) according to the treatment regimen. Progression-free survival (PFS) was used to evaluate the efficacy of quality-adjusted life year (QALY), and European Quality of Life-5 Dimensions (EQ-5D) index was used to evaluate quality of life. The t -test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups; the number of surgeries, length of hospital stay, treatment cost, and incremental cost-effectiveness ratio (ICER) were calculated for the two groups, and then a cost-effect analysis was performed. Results Within the PFS time, the per capita hospital cost was 96 446 yuan in the CBATO group and 91 230.43 yuan in the cTACE group. There were significant differences between the two groups in the mean number of surgeries (2.5±0.7 vs 3.4±0.8, t =16.911, P < 0.01) and mean hospital stay (5.8±1.2 days vs 7.5±1.8 days, t =12.459, P < 0.01). The CBATO group had a significantly higher QALY than the cTACE group (0.804 vs 0.512). Compared with the cTACE group, the CBATO group had an ICER of 17 861.53 yuan/QALY for unresectable liver cancer. Conclusion Although CBATO has a higher surgery cost than cTACE, CBATO has a better clinical effect than cTACE and can reduce the number of surgeries and length of hospital stay, with a better postoperative quality of life than cTACE, suggesting that CBATO has marked cost-effect advantages.

ABSTRACT
ObjectiveTo investigate the effect of arsenic trioxide-loaded CalliSpheres beads (CBATO) in transarterial chemoembolization (TACE) in the treatment of rabbits with VX2 liver tumor. MethodsA total of 120 tumor-bearing rabbits were divided into control group, CalliSpheres beads (CB) group (blank beads for TACE), CBATO group, and conventional TACE (cTACE) group (arsenic trioxide lipiodol for TACE) using a random number table, with 30 rabbits in each group. Five rabbits in each group were sacrificed at 12 hours and on days 3, 7, and 14 after TACE, and immunohistochemistry was used to measure the proliferation index and apoptosis percentage of tumor cells in the residual tumor area. The tumor necrotic volume was measure on day 7 after TACE, and the growth rate and necrosis rate of tumor cells were calculated. Ten rabbits were randomly selected from each group for the observation of survival time. An analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups; the Kaplan-Meier survival analysis was used to evaluate survival time, and the log-rank test was used for comparison. ResultsOn day 7 after TACE, the CBATO group had a significantly lower growth rate and a significantly higher necrosis rate of tumor cells than the cTACE group, the CB group, and the control group (all P＜0.05). At each time point after TACE, there were significant differences in the proliferation index and apoptosis percentage of tumor cells between the CBATO group and the other three groups (all P＜0.05). The median survival time was 26 days in the CBATO group, 18.5 days in the CB group, 22 days in the cTACE group, and 15.5 days in the control group, and the CBATO group had a significantly longer survival time than the other three groups (χ2=3.95, 8.99, and 13.47, P=0.049, P=0.003, and P＜0.01). ConclusionCBATO has a better effect than cTACE and CB in the treatment of rabbits with VX2 liver tumor and can significantly improve tumor necrosis rate, promote the apoptosis of tumor cells, and prolong the survival time of experimental animals.
ABSTRACT
Objective:To investigate the morphological feature and clinical significance of MRI around tumor after drug-eluting bead transcatheter arterial chemoembolization (DEB-TACE) of primary hepatocellular carcinoma.Methods:We reviewed and analyzed the data of hepatocellular carcinoma patients admitted from January 2017 to December 2018 in the Department of Radiological Intervention of the First Affiliated Hospital of Zhengzhou University. A total of 42 patients were enrolled, including 35 males and 7 females, aged (57.0±11.9) years. For the first time after operation, MRI enhancement showed peri-tumor margin enhancement as the starting point of follow-up. Follow-up and measure enhanced edge thickness, delayed enhancement, progression or remission data.Results:A total of 49 tumors and 84 peritumoral enhancement margins were included in 42 patients, with 30 sharp type , 40 rough type and 14 nodular type. The thickness of sharp type is less than that of rough type and nsodular type, and the differences were statistically significant (all P<0.05). The sharp type is the majority of the tumors with maximum diameter <5 cm, rough type and nodule type are the majority of tumors with maximum diameter ≥5 cm. Most of the sharp type are continuously enhanced, while the rough type and nodular type are not. Most sharp type relief (93.3%, 28/30), while rough type (80.0%, 32/40) and nodular type ( n=12) are mostly of deterioration, the differences are statistically significant (all P<0.05). Conclusion:Compared with the rough type and nodular type, the sharp type usually occurs in smaller tumors and more prone to local mitigation in the enhanced morphology around MRI after DEB-TACE in primary hepatocellular carcinoma.
ABSTRACT
Objective:To evaluate the curative effect, safety and feasibility of percutaneous transhepatic cholangio drainage(PTCD) combined with balloon dilatation in treating benign biliary-enteric anastomosis stricture(BBES).Methods:The clinical data of 33 patients with benign biliary-enteric anastomosis stricture, who were admitted to the First Affiliated Hospital of Zhengzhou University during the period from January 2013 to May 2019, were retrospectively analyzed. There were 23 cases of benign etiology and 10 cases of malignant etiology, benign strictures of which 15 cases were located in the hepatic hilum and of which 18 cases outside of it. All patients were considered as benign stenosis by at least two imaging examinations of magnetic resonance imaging of pancreatic or enhanced MRI or enhanced CT, laboratory examinations of tumor markers and other clinical data before operation. 10 cases of malignant etiology were confirmed by intraoperative biopsy and pathology. All patients were treated with balloon dilatation at an interval of 1 to 4 weeks after PTCD. The changes of clinical symptoms, bilirubin and liver function before and after operation were compared and analyzed, and the postoperative complications and anastomotic patency rate were followed up.Results:PTCD combined with balloon dilatation was performed successfully in all patients, and the success rate was 100%. After operation, the benign biliary-enteric anastomosis stricture was significantly improved in all patients, and the clinical symptoms were improved obviously. The liver function and bilirubin decreased significantly in all patients after operation, and there was significant statistical significance ( P<0.05). There is no serious complications such as biliary bleeding and biliary fistula were found after operation. At 3 months, 6 months, 12 months, 24 months and 36 months after operation, the anastomotic patency rates of all patients were 90.9%(30/33), 72.7%(24/33), 63.6%(21/33), 63.6%(21/33), 60.6%(20/33), respectively. During the whole follow-up period, anastomotic restenosis happened in 13 patients, of which 9 cases with restenosis, the benign stenosis site of the anastomosis was the hepatic hilum and of which 4 cases located on the outside of the hepatic hilum. After treatment, the incidence of benign restenosis of the anastomosis at the hepatic hilum (60.0%, 9/15) was higher than that at outside of the hepatic hilum (22.2%, 4/18) and it's statistically significant ( P<0.05). Among the 13 patients with recurrence of BBES, 4 cases underwent choledochojejunostomy for malignant causes and 9 cases with benign causes. The recurrence rates after the first balloon dilatation were 40.0% (4/10) and 39.1% (9/23), respectively, and the average recurrence time was 5.8 months and 6.8 months respectively, the difference was not statistically significant( P>0.05). Conclusion:For the treatment of benign biliary-enteric anastomosis stricture, percutaneous transhepatic cholangio drainage combined with balloon dilatation with reliable curative effect, with high safety and less trauma, with less operative complications, and with repeatability, so it is worth applying in clinic.
ABSTRACT
Objective To study pharmacokinetics and tissue distribution of CalliSpheres Beads (CB) loaded Arsenic trioxide (ATO) on rabbit VX2 liver tumor by transcatheter arterial chemoembolization (TACE). Method Sixty four rabbits with VX2 liver tumors were randomly divided into 4 groups: control group, CB group, CBATO group and cTACE group. Blood samples were taken at specific time points after TACE.The blood concentration of ATO,liver and kidney functions were examined respectively. In each group, every 4 rabbits were sacrificed on 1 days,3 days,7 days and 14 days after operation. The tumor,liver,kidney, lung,heart and muscle were taken to detect the drug concentration. Bilateral t?test was used to compare the drug concentration in blood and tissue between CBATO group and cTACE group. Results Statistically,The levels of ALT and AST in group CBATO and cTACE on 1st,3rd and 7th days after TACE were significantly higher than those in CB group(ALT: F=25.872, 17.69, 7.016, AST: F=46.365, 32.385, 12.548, P<0.05) respectively. The ALT and AST levels in CBATO group were statistically lower than those in cTACE group (ALT: t=0.369, 0.432, 0.169, 0.353, AST: t=0.488, 0.593, P>0.05). There were no statistically significant differences in the levels of BUN and Scr between the four experimental groups at each observation time point. Statistically, 10 minutes and 20 minutes after TACE, the blood drug concentration inCBATO was significantly lower than that in cTACE (t=7.675, 6.461, P<0.001). while 12 hours after operation,blood drug concentration in CBATO group was higher than that in cTACE group. In tumor tissue,the concentration of ATO in CBATO was higher than that in cTACE,and there was no statistical differences on the 1st day after TACE(t=2.155, P=0.068), but there was a statistical differences between 3rd, 7th and 14th days (t=11.462, 7.624, 2.649, P<0.05). Conclusion CBATO could prolong the time of drug metabolism,increase the drug concentration in tumor tissue,and didn′t aggravate the damage of liver and kidney function.

ABSTRACT
Objective To evaluate the clinical effect of endovascular interventional therapy in treating Cockett syndrome associated with deep vein thrombosis (DVT) of left lower extremity.Methods The clinical data of a total of 256 patients with Cockett syndrome complicated by DVT of left lower extremity,who were admitted to authors' hospital during the period from January 2011 to January 2015,were retrospectively analyzed.The patients were treated with catheter-directed thrombolysis,balloon dilatation of the occluded or narrowed venous segment,and/or stent implantation.The circumference differences of the affected limbs before and after treatment and the long-term patency rates were compared.Results Of the 256 patients with Cockett syndrome complicated by DVT of left lower extremity,complete dissolution of thrombus was achieved in 232 (90.6％) and partial dissolution of thrombus in 24 (9.4％).The circumference difference of thigh and calf was (7.12±2.15) and (4.57±2.81) cm respectively before and after treatment.Iliac vein reconstruction was carried out in 206 patients,among them simple balloon dilatation was employed in 46 and balloon dilatation together with stent implantation was adopted in 160.The patients were followed up for 9-24 months with a mean of 15 months.In simple balloon dilatation group,3 patients lost touch with the authors during the following-up period,26 patients (60.5％) developed iliac vein occlusion and post-embolization syndrome occurred in 21 patients (48.8％).In balloon dilatation plus stent implantation group,11 patients lost touch with the authors during the following-up period,stenosis or occlusion of the stent was seen in 13 patients (8.7％),post-embolization syndrome was observed in 15 patients (10.1％).The differences in vascular stenosis or occlusion and in the occurrence of post-embolization syndrome between the two groups were statistically significant (P＜0.001).Conclusion For the treatment of Cockett syndrome complicated by DVT of left lower extremity,catheter-directed thrombolysis and balloon dilatation combined with stent implantation carry definite clinical curative effect.
ABSTRACT
Objective To evaluate the safety and feasibility of step-by-step balloon dilatation combined with contineous biliary drainage in treating benign biliary-enteric anastomosis stricture.Methods The clinical data and imaging materials of 49 patients with benign biliary-enteric anastomosis stricture,who were admitted to authors' hospital during the period from January 2008 to March 2014 to receive treatment,were retrospectively analyzed.Before treatment,the diagnosis of benign biliary-enteric anastomosis stricture was confirmed in all patients by color Doppler ultrasound,MRI and/or contrast-enhanced CT scan,endoscopic or DSA-guided anastomosis biopsy.Among the 49 patients,23 patients (study group) were treated with percutaneous transhepatic step-by-step balloon dilatation (the diameter of used balloon was 8 mm initially,then 10 mm balloon was used in the second month,and 12 mm balloon was used in the third month) together with contineous biliary drainage (lasting for 6 months);26 patients (control group) were treated with single percutaneous transhepatic balloon dilatation (balloon diameter of 6 mm or 8 mm) plus biliary drainage (lasting for 6 months).The improvement of clinical symptoms,the incidence of postoperative complications,and the anastomotic patency rate were compared between the two groups.Results Technical success was obtained in all patients.No procedure-related complications,such as biliary tract hemorrhage and perforation,occurred.One week after the treatment,the difference in bilirubin level between the two groups was not statistically significant (P＞0.05).Although the difference in 3-month anastomotic patency rate between the two groups was not statistically significant,the 6-month,12-month and 24-month anastomotic patency rates of the study group were significantly higher than those of the control group (P＜0.05).Three patients in the study group developed recurrent jaundice at 11.2,14.3 and 17.6 months after treatment respectively;MRI and contrast-enhanced CT scan confirmed the diagnosis of anastomotic stricture recurrence,and balloon dilatation together with drainage tube placement had to be carried out again.In the control group,16 patients developed recurrent jaundice within 3.1-17.1 months after balloon dilatation management,among them one patient died of disseminated intravascular coagulation and the remaining 15 patients received balloon dilatation together with drainage tube placement again.Conclusion For benign biliary-enteric anastomosis strictures,step-by-step balloon dilatation combined with persistent biliary drainage is a safe and effective minimally-invasive treatment.

ABSTRACT
Objective To discuss the influence of different antitumor treatments on the survival time of patients with obstructive jaundice caused by cholangiocarcinoma located at middle-low segment of common bile duct after receiving PTCD. Methods During the period from Jan. 2012 to March 2013, a total of 60 patients with pathologically-proved cholangiocarcinoma located at the middle-low segment of common bile duct were admitted to authors’ hospital. According to tumor TNM staging, stage Ⅱ was seen in 9 cases, stage Ⅲ in 39 cases and stage Ⅳ in 12 cases. Based on the degree of cell differentiation, highly differentiated cancer was observed in 9 cases, moderately differentiated cancer in 37 cases, and poorly differentiated cancer in 14 cases. The 60 patients were enrolled in this study. Drainage tube placement and stent implantation were performed in all patients so as to relieve the symptoms of jaundice. According to the antitumor treatment used, the 60 patients were randomly and equally divided into three groups with 20 patients in each group. Draining procedure with subsequent regular arterial infusion chemotherapy was employed in the patients of group A; draining procedure with subsequent particle chain placement in biliary tract was performed in the patients of group B; and draining procedure with subsequent regular arterial infusion chemotherapy together with particle chain placement in biliary tract was carried out in the patients of group C. The results were analyzed using SPSS17.0 statistical software. The death factors of patients were statistically evaluated by using multivariate Cox proportional hazards regression analysis method, P0.05). The risk of death in group B was not significantly different from that in group A (HR=1.012, 95%CI 0.558-2.179); while the treatment mode of group C was a protection factor of death (HR=0.334, 95%CI 0.148-0.075). Conclusion The TNM stage and treatment mode can influence the survival time of patients with cholangiocarcinoma located at the middle-low segment of common bile duct. Therefore, for the treatment of obstructive jaundice caused by cholangiocarcinoma, combination use of regular arterial infusion chemotherapy and particle chain placement in biliary tract should be employed immediately after draining procedure as this therapeutic mode can effectively prolong patient’s survival time.
