| Abstract:: |
| Objective To analyze the qualified rate of the fiducial markers during 3D-printing co-planar template assisted CT-guided implantation in stereotactic body radiation therapy by CyberKnife,and to explore the cause of the unavailable markers in order to provide the reference for the fiducial implantation, treatment planning and radiotherapy delivery. Methods From March to December 2017, a total of 52 cases were planned to stereotactic body radiation therapy(SBRT) using CyberKnife by fiducial tracking, and the fiducial markers were implanted based on CT-guided 3D-printing co-planar template, including 22 in lung, 12 in liver, 5 in mediastinal lymph node, 8 in retroperitoneal lymph node, 3 in pancreas, each in celiac and pelvic lymph nodes, respectively. Except 7 cases not fit for CyberKnife treatment, 45 cases finished the treatment of CyberKnife, but there were 3 cases changed to spine tracking due to unqualified fiducial markers. The number of fiducial markers used and the qualified rate of fiducial markers were analyzed,and the cause of unqualified fiducial markers was studied.Results A total of 131 fiducial markers were impanted into 42 cases who finally received the treatment of CyberKnife by fiducial tracking,including 85 fiducial markers qualified(64.89%) and 46 fiducial markers unqualified (35.11%). The main causes of the unqualified fiducial markers varied, including outrange of rigidity error(26.08%), fiducial markers unavailable(41.31%), and other (32.61%).Conclusions The 3D-printing co-planar template assisted CT-guided implantation could reduce the number of puncture needles used,help to decrease the risk of puncture and trauma and the incidence of complications after the fiducial markers implantation. However, the fiducial markers implanted by this way would be abandoned by a variety of causes and should be taken into account before the fiducial markers implantation. |
