The continuous development of high-throughput sequencing (NGS) technology and the significant reduction in sequencing costs have provided favorable conditions for the realization of precise and accurate treatment of tumor patients in clinical practice. Annoroad has earnestly selected 868 genes that are closely related to tumors, covering all the genes recommended by the guidelines and clinical hotspot genes, and analyzes the relationship between 288 targeted drugs/immunization drug and gene variants, helps with gene detection in cancer patients, especially for those with recurrence and metastasis at advanced stage.
