Hunan Cancer Treatment Hospital-Xiangya Boai Tumor Rehabilitation Center: Professor Li Dingfeng’s “Technology for Tumor Treatment”

Former Tumor Hospital of Chinese Academy of Medical Sciences, now Professor Li Dingfeng of Xiangya Boai Tumor Rehabilitation Center, adopts the international advanced chemotherapy-surgery-chemotherapy model, and tumor hyperthermia combined with subcutaneous implant arterial chemotherapy technology to treat limb bone tumors, shortening the treatment Cycle, improve the efficacy. It provides conditions for preserving limbs, joint ligaments and joint capsules. &nbsp. Osteosarcoma is a very malignant bone-derived tumor that harms young adults. It usually grows near the joints. Surgical treatment alone often results in limbs difficult to preserve, rapid lung metastasis and death. Although some surgeries preserve limbs, they cannot preserve joint ligaments and joint capsules, thus losing limb function, seriously affecting the patient’s quality of life, and prone to recurrence and metastasis. &nbsp. Xiaojie, who should have enjoyed his innocence, is 9 years old this year, unfortunately suffering from osteosarcoma of the upper right tibia. Both Beijing and Shanghai hospitals said that they would have their limbs amputated. Xiaojie’s mother couldn’t bear it. How could such a small child live, walk, and face the eyes of other classmates. Xiaojie’s mother asked around and learned from the doctor at the local People’s Hospital that there is a doctor in China who is very authoritative in treating bone tumors. So Xiaojie’s mother bought a ticket overnight and found Professor Li Dingfeng, hoping that Professor Li could give the child “a line of life”. &nbsp. After reading Xiaojie’s information, Professor Li told Xiaojie’s mother that although it was difficult, he would try his best to keep the child’s legs. Hearing these words, Xiaojie’s mother wept in excitement, and the child was finally saved! ! Professor Li adopts subcutaneous implanted arterial chemotherapy technology for preoperative neoadjuvant chemotherapy-surgery-postoperative neoadjuvant chemotherapy, combined with deep tumor hyperthermia to “strangle” tumor cells in the “hibernation” stage, successfully saving Xiaojie Right leg. Before chemotherapy&nbsp.The tumor boundary is not clear&nbsp.After 1 preoperative neoadjuvant chemotherapy&nbsp.&nbsp.The tumor boundary becomes clear&nbsp.After 3 preoperative neoadjuvant chemotherapy&nbsp.The tumor boundary is clear and reaches the indication for surgery&nbsp.Surgery Later, Xiaojie was replaced with artificial joints, which not only preserved Xiaojie’s legs, but also preserved its function&nbsp.&nbsp. Postoperative tumor cell fatality rate, the content is 0&nbsp. Professor Li Dingfeng from Xiangya Boai Tumor Rehabilitation Center to improve chemotherapy In the role of limb osteosarcoma, it can effectively solve the recurrence of tumor tissue. It has changed the traditional method of intravenous chemotherapy in most domestic hospitals and adopted subcutaneous implanted catheter chemotherapy + deep tumor hyperthermia. Not only can the tumor continuously receive high-concentration chemotherapeutic drugs, the curative effect is improved, and the side effects of chemotherapy on the organs are greatly reduced. In addition, deep tumor hyperthermia can increase the effect of chemotherapy drugs, and at the same time “strangle” tumor cells in “subclinical focus” and “hibernation” of the tumor, so that cancer cells have no chance of breathing. The patients treated by Professor Li Dingfeng not only saved their lives but also their functional legs.

Subcutaneously-embedded arterial-guided chemotherapy technology: seeking for the salvation of limbs for cancer patients

Recently, the editor has met Li Dingfeng, an oncology expert in China. It is understood that he uses subcutaneous implantation of chemotherapy pump technology to improve the cure rate of bone tumors from 20% to 30% in the past to about 80% now, and bone tumors and soft tissue malignant tumors that are not sensitive to traditional chemotherapy, through this After the technical chemotherapy, the results of life-saving, limb-saving and function-saving were achieved. Subcutaneous implantable chemotherapy technology pioneered China’s osteosarcoma. Xian Gang, who used a chemotherapy pump to save life and protect limbs, participated in the clinical work of bone tumors. Li Dingfeng often saw some patients with painful bone tumors. Because of the traditional chemotherapy, radiotherapy and surgery at the time Not ideal, so the mortality rate is very high. An opportunity to go to Japan to study, so that the problems that have troubled him for three years finally found a good solution. He said: “At that time, along with the professor’s rounds, I saw an injection medicine pot buried in the patient’s body, and injected medicine into the medicine pot every once in a while. Then I learned that the medicine pot was a subcutaneously embedded arterial chemotherapeutic device. Through this arterial chemotherapeutic device, continuous delivery of chemotherapy to the lesion area to achieve the best results.” After returning home, Li Dingfeng introduced this technology into the field of osteosarcoma treatment, and at the same time, “chemotherapy-surgery-chemotherapy” this international The treatment model has also been added, and the two treatment technologies are added together, creating a precedent for the application of chemotherapy pumps to save life and limbs in osteosarcoma in China. There is a folk saying that patients with cancer did not die on the tumor, but died on the side effects of chemotherapy. Professor Li Dingfeng pointed out to the editor, “Because the toxic and side effects of chemotherapy are too large, it will kill normal cells as well as tumor cells. How to minimize the toxic and side effects of chemotherapy is urgent for every oncologist. The problem to be solved. This is also the main purpose of my training in Japan. After I arrived in Japan, I saw experts use special chemotherapy pumps to treat patients, and the effect was very good. At that time, I thought that if this technology was introduced into China, it would be used for treatment. Bone tumors will be a good choice. The treatment principle of this chemotherapy pump is: direct administration to the proximal end of the tumor’s blood supply artery, and the drug properties have always been high peak, so that the drug delivery method is ideal while avoiding the drug to other parts Caused by damage, it can be said that subcutaneous implantation of chemotherapy pump technology is the most ideal treatment. Subcutaneous implantable arterial chemotherapy technology improves drug concentration and reduces toxic and side effects. During the interview, Professor Li Dingfeng took out the chemotherapy pump to the editor. The editor saw this The chemotherapy pump is a plastic injection pot with a catheter connected underneath, with a radius of 1.5 cm. At this time, he plunged the syringe containing the medicine into the silicone pad, and the catheter immediately flowed out of the medicine. When the syringe was pulled out, the silicone pad automatically closed and would not There is arterial blood flow. The advantages of subcutaneous implantable arterial chemotherapy: 1. The local tumor drug concentration is significantly increased, and the concentration of the chemotherapy drug and its efficacy are within a certain range. There is a significant dose-effect relationship ratio: each time the concentration of the chemotherapy drug increases, Its curative effect can be improved by about 10 times. Large doses of chemotherapeutic drugs first enter the body and flow through the tumor area. Local high-concentration chemotherapeutic drugs directly act on the tumor cells in the molecular prototype, and directly enter the tumor cells through physical diffusion to achieve effective concentrations. 2. Local arterial chemotherapy avoids drugs that have not flowed through the tumor when administered intravenously, and first loses the anti-tumor effect under the degradation of the liver. 3. Subcutaneously implanted arterial chemotherapy continues to be administered, which is helpful to keep the effective drug in the tumor blood supply area high Concentration time. 4. Subcutaneous implantable arterial chemotherapy device can establish a permanent local arterial infusion chemotherapy channel, which can be intervened multiple times before and after surgery. It is simple and easy to reduce the pain of patients and save costs. Professor Li Dingfeng said that chemotherapy The catheter of the pump can be buried in the body for a long time, and there is no harm to the human body. During the treatment, Chinese medicine is used to assist chemotherapy to reduce the pain of the patients and make them more acceptable, so as to achieve better efficacy. Patented technology loves it According to relevant information, the next visit to the new students: bone tumors are divided into two types, one is the juvenile type, the other is the middle-aged type. The juvenile type is mainly primary, and the middle-aged and old people are generally secondary tumor metastasis. In this regard, Li Dingfeng explained that adolescents may be in the stage of skeletal development, and the backbone is relatively active, so it is easier to get the disease, but the cause of the disease, there is no relevant statement in medicine. As for the metastases of the elderly, the tumors are caused by tumors in other parts The cells are transferred to the bone, because the tumor cells flow with the blood, and are transplanted wherever they flow. Although bone tumors are not high incidence, they are not at all
