Clinical efficacy of implantation of 125Ⅰ particles in the treatment of advanced pancreatic cancer / 中华肝胆外科杂志

ABSTRACT

Objective To study the clinical efficacy of intra-operative implantation of 125Ⅰ particles to treat advanced pancreatic cancer,and to evaluate the treatment effects on pain relief and survival of patients.Methods A retrospective study was conducted on 53 patients who were treated in the Third Affiliated Hospital of Inner Mongolia Medical University from May 2013 to November 2016.The patients were divided into the particle implantation group (n =32,palliative operation combined with intra-operative implantation of 125Ⅰ particles or just intra-operative implantation) and the control group (n =21,palliative operation).The outcomes on pain relief and median survival after operation were compared between the 2 groups.Results Patients in the implantation group were implanted with 20 to 70 (41.4± 12.1) particles.There were no postoperative complications such as pancreatic fistula and bleeding.There was also no perioperative death.Of the 46(86.8％) patients who were followed-up,three patients were still alive at the time the data were analyzed.The postoperative survival time of the patients ranged from 3 to 27 months.For the implantation group,the median survival time was 11.5 months.The 3-,6-,12-,24-months survival rates were 100.0％,90.6％,65.6％,15.6％,respectively.Postoperative pain relief happened in 92.6％ of patients.For the control group,postoperative survival time ranged from 2 to 17 months.The median survival time was 7 months.The 3-,6-,12-,24-months survival rates were 95.2％,57.1％,9.5％,0,respectively.Postoperative pain relief happened in 16.7％ of patients.Postoperative pain relief for patients in the implantation group was significantly better than the preoperative,and than patients in the control group (both P ＜ 0.05).The Log-rank test showed a significant difference in survival between the two groups (P＜0.05).Conclusion Particle implantation significantly relieved pain and prolonged survival time of the patients.
