In recent years, most of our patients with malignant tumors have lost the opportunity of surgery when found, radioactive iodine-125 particle implantation minimally invasive implantation into the tumor, microtrauma, high-efficacy tumor reduction treatment, avoid over treatment, reduce the occurrence of radiotherapy, chemotherapy and surgical treatment side effects, greatly reduce unnecessary medical costs, save medical resources, reduce medical investment. The municipal continuing medical education project "Application of radioactive iodine 125 particles in the treatment of Malignant Tumors (C22-01-104010107)", sponsored by Chengdu Hi-tech Medical Association and undertaken by Chengdu Jing Dong Hospital, was held online on November 19, with a total of more than 500 students participating.

Experts respectively from the application of iodine-125 particles in lung cancer, the clinical application of radioactive 125I particles, CT-guided percutaneous puncture of narrow abdominal space lesions, the application of interventional ultrasound technology in abdominal surgery and other topics made wonderful speeches, the content of the simple, received unanimous praise from the participants.

The training is rich in content and practical, which has been praised by the students. It has solved many doubts in the work and laid a solid foundation for the better implementation of particle implantation therapy, benefiting more patients.
