Three Gorges Evening News (all media reporter Gao Yuan correspondent Tan Yunfei Huang Xing) “I’m so happy! I reviewed the CT today and found that the tumors in the lungs have basically disappeared.” On March 15, at the Second People’s Hospital of Yichang City In the tumor hospital, 78-year-old Granny Wan was very happy to see the results of the re-examination. She only needs to have regular re-examinations in the later period.
Two years ago, Granny Wan was diagnosed with advanced colon cancer and metastasized to the liver and lung. After systemic chemotherapy and targeted therapy in the Fourth Department of Radiotherapy and Chemotherapy of the Second City Hospital, the lesions were significantly reduced, and then passed The primary tumor located in the colon was surgically removed, and the liver metastases were removed by microwave ablation. However, due to the limitations of the equipment at that time, the radiotherapy could not be accurately positioned, and there was still a residual tumor with a diameter of about 2.8 cm in the left upper lung.
In November last year, the Second Hospital introduced the first Varian Speed Accelerator in Yichang, so the body stereotactic radiotherapy technology was used, and it took only 3 weeks and 9 times of radiotherapy to treat Granny Wan’s lungs. tumor clearance.
“‘Body stereotactic radiotherapy’ is a cutting-edge technology for the treatment of tumors, and Granny Wan is also the first patient to try this technology. For example, conventional radiotherapy is equivalent to using a machine gun to kill a large area, while stereotactic radiotherapy is the first patient to try this technology. Radiotherapy is a precise strike with a sniper rifle, which can kill tumor cells to the greatest extent and minimize damage to normal tissues.” Director Li Xin of the Cancer Radiation Therapy Center of the hospital introduced that if Granny Wan is treated with conventional radiotherapy, at least It takes 2 months and about 30 times of radiotherapy to clear, and each radiotherapy lasts 15-20 minutes. With this technology, not only the time of each radiotherapy is shortened to 5 minutes, but the number of radiotherapy is only 6-8 times, which not only shortens the hospitalization time, but also improves the treatment effect.
