The current clinical applications of cfDNA mutation testing are the identification targeted therapies in non-small cell lung cancer (NSCLC) by testing for epidermal growth factor receptor (EGFR) mutations, and the assessment of Kirsten RAt Sarcoma (KRAS), Neuroblastoma RAS viral oncogene homologue (NRAS) and v-Raf murine sarcoma viral oncogene homologue B (BRAF) mutation status in patients with colorectal cancer (CRC), in situations when molecular testing is not feasible on tissue due to insufficient/inadequate material or inability to perform a biopsy [4]. Here, BRAF is linked to non-small cell lung carcinoma.
