Abstract:
Pancreatic cancer is highly malignant and difficult to treat. The implantation of radioactive seed has opened up a new treatment option for pancreatic cancer. Although the implantation of radioactive seed in the treatment of pancreatic cancer has achieved good results, due to the special anatomical location of pancreatic cancer and the dense distribution of important tissues and organs around the tumor, the operation of seed implantation for pancreatic cancer has become a clinical treatment challenge. We applied the method of 3D printing template navigation and constraining the direction of the puncture needle. The puncture needle followed the safe puncture path designed in the preoperative treatment planning system, effectively avoiding important tissues and organs, and implanted radioactive seeds in the tumor. The operation of seed implantation was simplified, homogenized and made safe. In this group of cases, the proportion of successful particle implantation using 3D printing template navigation was 89.5%. All cases met the preoperative treatment plan in postoperative dose verification and achieved the purpose of radioactive seed implantation treatment.
