The utility of immunohistochemistry (IHC) as an alternative approach for detection of BRAF(V600E) in the thoracic metastases of sporadic mCRC patients has not been evaluated until now.
BRAF V600E also predicts poor prognosis in microsatellite stable colorectal cancers and may be a marker of resistance to anti-EGFR therapy in metastatic disease.
Furthermore, in a meta-analysis, 3 additional SNPs were significantly associated with SLN metastasis (EGFR rs723526 and TLR3 rs3775292) and melanoma-specific death (TLR3 rs7668666).
