The effect of minimally invasive surgery in our country is significant

Minimally invasive surgery for cancer has gradually matured in China. More than 26,000 operations are performed each year, and the treatment technology and cancer cure rate have reached the international advanced level.

According to experts, China currently has about 2.3 million cancer patients each year, and there are 900,000 new cases of liver cancer and lung cancer each year. Due to the low rate of early diagnosis of cancer, more than 60% of patients have been diagnosed at the middle and late stages, and less than 20% of patients undergoing conventional radical resection have lost the possibility of disease-free survival.

The use of magnetic resonance, color ultrasound, surgical navigation systems and other forms of minimally invasive surgery for the treatment of tumors, with accurate positioning, less trauma, fewer complications, a wide range of adaptation, the patient's body against minor, can maximize the protection of human organ and other advantages . Clinical statistics show that more than 60% of patients with advanced and advanced diseases can obtain the opportunity for radical treatment of tumors through minimally invasive surgery.

According to data provided by Prof. Zheng, the tumor minimally invasive intervention center of You'an Hospital in Beijing used radiofrequency ablation and microwave ablation techniques for patients with advanced hepatocellular carcinoma who could not undergo traditional surgical treatment, and achieved the possibility of disease-free survival in patients with advanced tumors. At present, 487 patients with advanced hepatocellular carcinoma are treated. The maximum tumor diameter is 12 cm. The 1-year survival rate is 97.7%, and the 3-year survival rate is 71%. Using arterial chemoembolization combined with radiofrequency or microwave ablation, 133 cases of these patients were treated in the past 3 years. The 1-year survival rate was 87%, and the 3-year survival rate reached 41.4%. This technology has reached the international advanced level.

Beijing Xuanwu Hospital explored the use of minimally invasive radiofrequency ablation in patients with non-small cell lung cancer who were over 75 years of age, had advanced comorbidities, poor cardiopulmonary function, and could not tolerate thoracotomy and radiotherapy and chemotherapy. Using a combination of molecular targeted drugs to treat more than 400 patients with non-small cell lung cancer, the maximum tumor ablation rate was 13 cm, which effectively improved the survival rate of the patients. The 2-year survival rate of the first 100 patients receiving radiofrequency ablation reached 57.7. %.

The ultrasound ablation treatment of pancreatic cancer carried out by the People's Liberation Army 307 Hospital made it possible for 168 patients with advanced pancreatic cancer to achieve a one-year survival rate of more than 50% and a three-year survival rate of more than 15%, effectively extending the survival period of patients.

Professor Zheng said that in order to further promote the popularization of minimally invasive therapeutic techniques for cancer, in April this year the Ministry of Science and Technology approved the Chinese Association for the Minimally Invasive Treatment Industry Technology Innovation Alliance as a national pilot alliance. At present, there are more than 1,600 physicians engaged in tumor ablation therapy throughout the country that have received various types of professional and technical training. The coalition recommends that hospitals with conditions set up operating rooms with CT, magnetic resonance, ultrasound, digital subtraction equipment and minimally invasive interventional techniques, and establish minimally invasive interventional wards to further improve the safety and effectiveness of minimally invasive surgery. The Alliance will establish 10 minimally invasive therapeutic tumor centers and 100 minimally invasive treatment tumor demonstration hospitals, and actively promote all kinds of advanced minimally invasive treatment of tumor technology, so that more cancer patients receive effective treatment. ”

It is known that China's Strategic Alliance for Minimally Invasive Treatment Technology for Cancer has published and issued ablation treatments for hepatic tumor monographs, radiofrequency ablation treatment procedures, and a variety of minimally invasive ablation procedures. The governing unit of the Union has now obtained two major national science and technology support projects for the “Twelfth Five-Year Plan” and a special topic for major communicable diseases.

More than 500 experts and representatives from 28 provinces, autonomous regions and municipalities across the country have carried out techniques for the ablation treatment of special parts of liver cancer, ablation of lung tumors, ablation of bone tumors, ultrasound focusing, brachytherapy with particle implanted tumors, and laparoscopic techniques.
