The KRAS/BRAF/PIK3CA Array provides rapid detection of mutations within KRAS, BRAF and PIK3CA genes, to aid in the selection of patients for appropriate treatment of metastatic colorectal cancer. Despite recent therapeutic advances, the prognosis for patients with metastatic CRC (mCRC) remains poor. Early treatment is therefore critical. This array allows the clinician to correctly select appropriate patients for anti-EGFR therapy, thereby maximising drug efficacy and minimising adverse side effects to the patient. Mutations in the KRAS gene are known to disrupt the EGFR pathway, rendering anti-EGFR therapy ineffective. Presence of KRAS mutations accounts for approximately 35-45% of non-responsive patients. Oncogenic mutations in genes encoding key downstream effectors within the EGFR-s...Read more
