Tumor is a complex disease caused by multi-stage and multi-gene mutation accumulation. The process of malignant transformation of normal cells into cancer cells includes the initiation stage, promotion stage and progression stage. In the ultra-early stage of tumor formation, which is the above-mentioned start-up phase, necrosis and apoptosis of tumor cells will occur. These apoptotic or necrotic tumor cells will release their DNA into peripheral blood to form free DNA, which is detected by ultra-high sensitivity The technology can detect tumor free DNA in peripheral blood to assess whether the mutation signals of tumor-related pathogenic genes are abnormal, and can achieve the purpose of early tumor screening for some high-risk groups.
Early Screening No. 1-Circulating Tumor DNA Test Project Detects 11 common hotspot genes related to tumorigenesis and development, including 65 hotspot gene mutation sites, covering 15 common malignant solid tumors abnormal.
