Abstract: Objective To evaluate the feasibility of 3D print individual template and CT-guided 125I seed implantation for malignant tumors. Methods A total of 30 patients were involved in this study. Before 125I seed implantation, the patients received CT simulation orientation as the predicted posture. The individual template was designed by the brachytherapy treatment planning system(BTPS), and printed by 3D print technique. Every patient received 125I seed implantation under the guidance of 3D print individual template and CT scan. After implantation, treatment quality was evaluated with CT and BTPS. Results The 3D print individual templates were successfully designed and manufactured. Of all 30 cases, 28 were successfully implanted with the 3D print templates, and 2 failed. Of the 28 successful cases, 22 had the same number of seeds implanted as scheduled before operation, and the other 6 cases optimized the number of seeds during operation. Postoperative evaluation indicated that 14(50.0%)cases had excellent implants, 10(35.7%)had good implants, 4(14.3%)had suboptimal implants, and no case had poor implants. Conclusion The 3D print individual template and CT-guided 125I seed implantation appears to be a feasible, safe and effective modality for the treatment of malignant tumors.
