摘要: In recent years, several predictive and prognostic biomarkers have been established in colorectal cancer (CRC). The RAS-mutation status is widely applied the daily routine diagnostic as biomarker for treatment with EGFR-inhibitors. A BRAF- mutation has no value this context. detection of high-grade microsatellite instability (MSI-H) a response to 5-Fluoruracil-monotherapy. Prognostic CRC are MSI-status mutational BRAF. According current WHO classification poorly undifferentiated MSI-associated special morphological subtypes molecular graded depending on their MSI-status. BRAF-mutation context stability (MSS) associated very poor prognosis thus represents most aggressive subtype CRC. patients positive Bethesda criteria stepwise immunohistochemical scheme proposed.
