Percutaneous gold seed fiducials implantation in CT-guided for 132 solid tumors before cyberknife radiosurgery treatment / 肿瘤研究与临床

ABSTRACT

Objective To evaluate the technical points and security of CT-guided in percutaneous gold seed fiducials implantation for 132 solid tumors before cyberknife radiosurgery treatment. Methods 132 solid tumors were implanted with gold seed fiducials guided by CT before cyberknife radiosurgery treatment.The complications were analyzed. The methods for the prevention and treatment of the complications were suggested. Results Of 132 cases, the achievement rate of puncture was 99.2%(131/132), including 16 (12.1%) cases of pain in the location of puncture, 10(7.6%) cases of tachycardia, and 6 (4.5%) cases of hypertension. Among the 68 cases of lung cancer, there were 3(4.4%) cases of slight pneumothorax, 3(4.4%)cases of generous pneumothorax. Among the 50 cases of liver cancer, there were 1 (2.0%) case of gold seed fiducials transmigration, 2 (4.0%) cases of small amount bleeding from needle channel. Conclusion Percutaneous gold seed fiducials implantation in CT-guided for solid tumors before cyberknife radiosurgery treatment is a slight trauma and safe method.
