Can Microsatellite Status of Colorectal Cancer Be Reliably Assessed after Neoadjuvant Therapy?
18 May 2017
Abstract excerpt
Abstract Purpose: Determination of microsatellite instability (MSI) by PCR is the gold standard; however, IHC of mismatch repair (MMR) proteins is frequently performed instead. The reliability of these methods on postneoadjuvant therapy specimens is unknown. We examined the effect of neoadjuvant therapy on MSI results by PCR and IHC. Experimental design: A total of 239 colorectal cancers resected after...
