This study was performed to evaluate whether patients with locally advanced pancreatic cancer benefit from 125 ^I seed implantation. This retrospective study included 224 patients with locally advanced pancreatic cancer, with 137 patients（61.2%） in the implantation（IP） group and 87（38.9%） in the non-implantation（NIP） group. The survival status, complications and objective curative effects were compared between the groups. The average operative time in the IP group was significantly longer than that in the NIP group（243±51 vs. 214±77 min）. The tumor response rates were 9.5% and 0 at the 2nd month after surgery in the IP and NIP groups, respectively（P〈0.05）. The IP group exhibited a trend toward pain relief at the 6th month after surgery. The global health status scores of the IP group were higher than those of the NIP group at the 3rd and 6th month after surgery. The median survival time in the IP group was significantly longer than that in the NIP group. In conclusion, patients with locally advanced pancreatic cancer can benefit from 125 I seed implantation in terms of local tumor control, survival time, pain relief and quality of life.展开更多
