Cellular immunotherapy is an emerging new anti-tumor treatment with remarkable efficacy, which makes up for the drawbacks of traditional surgery, radiotherapy, side effects and chemotherapy, and has been recognized as one of the most active and promising treatments in the comprehensive tumor treatment model in the 21st century. It is also the only treatment that has the hope of completely eliminating tumor cells in the world at present. Treatment process: 1. A certain amount of peripheral mononuclear cells are collected from patients themselves by advanced blood cell separator. 2.In the GMP laboratory, single nucleated cells are separated and placed in culture bottles, and culture solution and cytokines are added to stimulate cell activation and value-added. 3.After 7~14 days of cell culture, the cell number increases to hundreds to thousands of times of the original number, and the immunocidal ability increases 20~100 times. 4.On the 7th~14th day after blood collection, the transfusion of DC and CIK cells will be started. 5.After several courses of treatment, it effectively kills tumor cells in patients’ body, promotes recovery and improves patients’ quality of life. According to the comparison of clinical treatment, the following tumor patients are most suitable to receive biological therapy: Early stage tumor patients: biological therapy can kill tumor cells precisely and improve the success rate of recovery;
