This test is a molecular diagnostic test that compares the expression of 12 cancer-related genes, including multiple tyrosine kinase receptors (RTKs), to identify the molecular characteristics of a patient's cancer cells.

Since it is possible to identify overexpressed RTK (Receptor tyrosine kinase) at the RNA level by quantitatively comparing the expression between the patient’s tumor tissue and non-tumor tissue, it can be the basis for using targeted therapies such as specific TKIs (Tyrosine kinase inhibitors).

It can be tested using the same sample when requested along with the chemotherapy response assay, and candidate drugs recommended based on the CGE results can be included in the chemotherapy response assay.

Types of cancer-related genes : VEGFR1, VEGFR2, PDGFR-α, PDGFR-β, EGFR, ErbB2, BRAF, FGFR1, ALK, c-KIT, Vimentin, vWF
