Huang Lijun, chief surgeon and deputy director of the Department of Thoracic Surgery at Tangdu Hospital, said: "In order to ensure the success of the operation, we performed an imaging analysis of the lesions of the children before surgery, and printed the child's sternum model and lesion model according to the images.
During the operation, the doctors bypassed the tumor site of the child and prevented the spread of cancer cells caused by intraoperative tumor rupture. At the same time, considering that the child is only 7 years old, the body will continue to grow and develop in the future, so after removing some of the child's ribs, we installed 3D printed artificial bone and titanium alloy ribs that can grow with him. . 
Why does a 7-year-old child have a 15 cm malignancy?
Because systemic sarcoma is high in the adolescent stage, and grows very fast.
Huang Lijun said: "The 7-year-old boy's rib tumor is a systemic sarcoma that is high in adolescents and grows very fast. Not long ago, a 10-year-old boy found a coin in the sternum 10 days before the test. The size of the mass, and later the family wants to have the child undergo surgery after the exam, the results, the day after the test is checked again from the size of a coin to the size of the table tennis."
How to prevent and treat systemic sarcoma?
Physical examination every year, if you find a mass on the body or continue to pain, hurry to the hospital. 
Huang Lijun said: "Systemic sarcoma is highly prevalent among adolescents and occurs mostly in long bones such as limbs. How to prevent it from being temporarily ignored, only parents should give physical examination to children every year, if they find that the child has an inexplicable bag If the block or child continues to have pain, it is necessary to hurry to the hospital for imaging examination to see what the mass is, not serious.
If it is confirmed to be a systemic sarcoma, it is more troublesome because the incidence of this disease is low in the tumor world, but the recurrence rate is high. Therefore, once diagnosed, it is necessary to quickly carry out surgery to prevent its spread. At the same time, other follow-up treatments are needed. â€
The 7-year-old child's future growth depends on three artificial ribs
What is the stress on this rib?
Huang Lijun said: "The materials used in the three ribs are made of artificial bone and titanium alloy, and they can continue to stretch and grow with the growth of the child. Its benefits: 1, does not limit the child's growth and development, 2 Its anti-stress ability is the same as that of human bones, so it can protect the human body's internal organs. 3. His interference in the imaging examination is very small, which is very helpful for the child's future imaging examination. â€
The operation was performed by Huang Lijun, deputy director of the Department of Thoracic Surgery of Tangdu Hospital, and the attending physicians Zhong Daixing, Wang Lei and Yang Sanhu as assistants.
