China News Service, June 28 (Chen Jing Zhongxuan) The reporter learned on the 28th that Chinese experts have successfully developed a multi-modal tumor radiofrequency treatment system through multiple technical iterations and repeated application verifications over 5 years. The relevant results have been transformed into a A complete set of equipment put into clinical application.
Relying on the national key research and development plan of the Ministry of Science and Technology, "Image-guided multimodal ablation treatment of solid tumor clinical solutions", the system developed by experts integrates ultra-low temperature freezing and radiofrequency heating, and transforms the freezing and radiofrequency heating process Completely disintegrated.
The reporter learned from Fudan University Affiliated Tumor Hospital on the 28th that this multi-modal tumor radiofrequency treatment system that integrates ultra-low temperature freezing and radiofrequency ablation therapy has been fully clinically tested.
The team of Professor Li Wentao, director of the Interventional Therapy Department, took the lead in successfully completing the multimodal ablation treatment of liver tumors.
Accurately guided by CT, the doctors inserted a needle to locate the tumor focus in the patient’s liver at a time, first freeze the focus with ultra-low temperature "liquid nitrogen" at nearly -200°C, and then heat the tumor with rapid heating "radio frequency". Modal ablation therapy quickly "eliminates" the tumor.
"Currently, the main methods for malignant tumors are surgery, chemotherapy, and radiotherapy. However, more than 50% of patients with primary liver cancer, metastatic liver cancer, and recurrent liver cancer are unable to undergo surgery or surgery due to physical tolerance or disease conditions. The effect of radiotherapy and chemotherapy, or conventional treatment is not satisfactory," said Professor Li Wentao.
The patients who were the first to receive treatment had multiple liver lesions and were unable to receive surgical treatment, and were unwilling to receive radiotherapy and chemotherapy.
Professor Li Wentao told reporters that the patient underwent multimodal ablation of liver tumors and achieved ideal results.
Professor Li Wentao told reporters that the multi-modal tumor radiofrequency treatment system can achieve multi-modal tumor treatment with only one needle insertion. Intraoperative visualization is conducive to the operation of doctors and can achieve precise control of tumor ablation boundaries, which has obvious advantages.
Compared with the traditional ablation technology, this new tumor treatment technology greatly reduces the frequency of treatment for patients, significantly reduces the occurrence of postoperative complications, and brings good news to tumor patients.
It is understood that ablation therapy is one of the most important treatment methods for malignant tumors. Among them, cryoablation based on low temperature killing and radiofrequency ablation based on high temperature damage to tumors are the most widely used and the most effective.
After 16 years of scientific research and exploration, the team of Professor Xu Xuemin from the School of Biomedical Engineering (Med-X) of Shanghai Jiaotong University took the lead in proposing the concept and method of multi-modal thermophysical immunotherapy, which greatly improves the efficiency of local thermal ablation of tumors and releases a large amount of Specific antigens stimulate the body to produce durable specific T cell anti-tumor immunity, effectively control tumor recurrence and metastasis, and improve survival rate.
The Department of Interventional Therapy of Fudan University Tumor Hospital and Shanghai Jiaotong University have jointly created a platform for "integration of medicine and industry" and integrated construction of industry, academia, research, and medicine. Aiming at the bottleneck problem of tumor interventional therapy, it has carried out all-round medical innovation for a long time. Research and development and technological achievement transformation.
Experts have successfully used multimodal ablation to accurately treat liver tumors, providing patients with the opportunity and possibility of "rebirth".
As to whether the application can be expanded to more solid tumors in the future, Professor Li Wentao said that further research is needed.
