As we all know, the most significant feature of tumor cells is that they divide infinitely and never stop. Once one appears, they will soon divide into countless others and develop extremely fast. The number of immune cells itself is small, and the speed of division is far from being able to keep up with it. When cancer cells become a climate, immune cells are usually helpless. At that time, patients usually have to resort to physical or chemical means such as surgery, chemotherapy, radiotherapy, etc. to destroy them. CIK cell immunotherapy, on the other hand, is to isolate lymphocytes from human peripheral blood, and after strict isolation, screening and induction culture, make them become immunologically active CIK anti-tumor cells, and then multiply these CIK anti-tumor cells more than 1000 times to reach a certain number and scale, and then infuse them back into human body, so that these specially trained and strengthened “special soldier” – CIK anti-tumor cells to fight with cancer cells, and if they fail once, then a second and a third time, until the cancer cells are eliminated. CIK cells induction culture have some special advantages: like radar, they can not only fully identify cancer cells in the body, but also automatically search for “enemies”, which include most solid tumors, tumors that are not sensitive to radiotherapy and chemotherapy, and metastatic tumors. These “enemies” include most solid tumors, tumors that are not sensitive to radiotherapy and chemotherapy, and metastatic tumors. Since it uses the body’s own cells to kill tumor cells, it is very safe and has no toxic side effects. At the same time, it also helps the body to initiate immunity, rebuild and improve the immune function of the patient’s whole body, and completely remove residual tumor cells and micro metastatic lesions in the body. The three golden periods of the best clinical application of CIK treatment: First, when the tumor is diagnosed and not metastasized, biological immunotherapy alone or with surgery can better and systematically kill the tumor cells! Second, when metastasis occurs after surgery, bioimmunotherapy combined with radiotherapy and chemotherapy can comprehensively remove residual cells and establish immune barrier to prevent metastasis! Third, in the middle and late stage when the disease is heavy and cannot tolerate radiotherapy and chemotherapy, biological immunotherapy can reduce various pains and ensure patients’ long-term survival with tumor! The Cancer Center of Jiangsu Provincial People’s Hospital successfully introduced CIK cellular immunotherapy technology as early as 2001 and won the first prize of Medical New Technology Introduction Award of Jiangsu Provincial Health Department in that year. With mature and stable technical methods, experienced physicians and advanced instruments and equipment, we have successfully treated thousands of patients so far, helping patients to improve their survival time and quality of life!
