Methods:A total of 82 cases of patients with advanced liver cancer who were treated in our hospital between September 2014 and December 2016 were collected, reviewed and then divided into the control group (n=45) who received TACE alone and the observation group (n=37) who received sequential125I particle chain implantation and TACE. Serum levels of tumor markers, angiogenesis indexes and apoptosis molecules before and after treatments were compared between two groups of patients.Results: Before treatment, differences in serum levels of tumor markers, angiogenesis indexes and apoptosis molecules were not statistically significant between two groups of patients. After treatment, serum tumor markers AFP, CA199, CA153 and Ferritin levels in observation group were lower than those in control group;serum angiogenesis indexes VEGF, PEDF, ES and bFGF contents were lower than those in control group;serum apoptosis molecules p53 and Fas contents were higher than those in control group.Conclusion:Sequential125I particle chain implantation and TACE treatment of advanced liver cancer can effectively reduce tumor malignancy and promote tumor apoptosis.展开更多

METHODS A retrospective analysis of our database was performed, and a total of 25 patients with pancreatic cancer who underwent iodine-125 seed implantation between January 2014 and November 2017 were analyzed. Of these, 12 implantations were assisted by a 3 D-printed coplanar template(group A), and 13 implantations performed freehand were selected as a control group(group B). A 3 D coplanar template was designed and printed according to a preoperative CT scan and treatment planning system. The iodine-125 seeds were then implanted using the template as a guide. Dosimetric verification was performed after implantation. Pre-and postoperative D90, V100, and V150 were calculated. The success rate of iodine-125 seed implantation, dosimetric parameters, and complications were analyzed and compared between the two groups.RESULTS Iodine-125 seed implantation was successfully performed in both groups. In group A, the median pre-and postoperative D90 values were 155.32 ± 8.05 Gy and 154.82 ± 16.43 Gy, respectively; the difference between these values was minimal and not statistically significant(P > 0.05). Postoperative V100 and V150 were 91.05% ± 4.06% and 64.54% ± 13.40%, respectively, which met the treatment requirement. A better dosimetric parameter was observed in group A than in group B, and the difference was statistically significant(V100: 91.05% ± 4.06% vs 72.91% ± 13.78%, P < 0.05). No major procedure-related complications were observed in either group. For group A, mild hemorrhage was observed in 1 patient with a peritoneal local hematoma due to mesenteric vein damage from the iodine-125 seed implantation needle. The hematoma resolved spontaneously without treatment. Postoperative blood amylase levels remained within the normal range for all patients.CONCLUSION A 3 D-printed coplanar template appears to be a safe and effective iodine-125 seed implantation guidance tool to improve implantation accuracy and optimize dosimetric distribution.展开更多

They were non-randomly assigned to undergo treatment with transarterial chemoembolization(TACE)/transarterial embolization(TAE) + portal vein stents combined with ^(125)Ⅰ implantation(Group A) and TACE/TAE + portal vein stents only(Group B). After the operation, scheduled follow-up was performed at 6, 12 and 24 mo. The recorded information included clinical manifestations, survival rate, and stent restenosis rate. Kaplan–Meier curves, log-rank test and Cox regression were used for data analyses. RESULTS From January 1, 2010 to January 1, 2015, 54 and 57 patients were allocated to Groups A and B, respectively. The survival rates at 6, 12 and 24 mo were 85.2%, 42.6% and 22.2% in Group A and 50.9%, 10.5% and 0% in Group B. The differences were significant [log rank P < 0.05, hazard ratio(HR): 0.37, 95%CI: 0.24-0.56]. The rates of stent restenosis were 18.5%, 55.6% and 83.3% in Group A and 43.9%, 82.5% and 96.5% in Group B. The differences were significant(log rank P < 0.05, HR: 0.42, 95%CI: 0.27-0.63). Cox regression identified that treatment was the only factor affecting survival rate in this study.CONCLUSION Main portal vein stents combined with ^(125)Ⅰ can significantly improve survival rate and reduce the rate of stent restenosis.展开更多

The occurrence of MPVTT is always a negative prognostic factor for patients with hepatocellular carcinoma(HCC).Therefore, attention should be paid to the treatment of MPVTT and its complications.AIM To evaluate the efficacy of transarterial chemoembolization/transarterial embolization(TACE/TAE)+^(125)I seeds implantation with transjugular intrahepatic portosystemic shunt(TIPS) in treating MPVTT and its complications.METHODS From January 2007 to March 2015, 85 consecutive patients with MPVTT were nonrandomly assigned to undergo treatment with TACE/TAE + TIPS and ^(125)I implantation(TIPS-^(125)I group) or TACE/TAE + TIPS only(TIPS only group) in Beijing Shijitan Hospital, and all clinical data were collected. During 24 mo follow-up, the incidence of overall survival, stent stenosis and symptom recurrence was analyzed to evaluate the efficacy of TIPS-^(125)I.RESULTS During 24 mo follow-up of all patients, we collected data at 6, 12 and 24 mo. The rates of survival were 80%, 45%, and 20%, respectively, in the TIPS-^(125)I group,whereas those in the TIPS only group were 64.4%, 24.4%, and 4.4%, respectively(P < 0.05). The rates of symptom recurrence were 7.5%, 22.5%, and 35%,respectively, in the TIPS-^(125)I group, whereas those in the TIPS only group were31.1%, 62.2%, and 82.2%(P < 0.05). The rates of stent restenosis were 12.5%,27.5%, and 42.5%, respectively, in the TIPS-^(125)I group, and 42.2%, 68.9%, and84.4%, respectively, in the TIPS only group(P < 0.05). TIPS-^(125)I was found to be significantly favorable in treating MPVTT and its complications in patients with HCC.CONCLUSION TACE/TAE+^(125)I combined with TIPS is effective in treating MPVTT and its complications, improving quality of life of patients and reducing mortality.展开更多
