 Serrated lesions include HP(hyperplastic polyp), TSA(traditional serrated adenoma), and SSA/P(sessile serrated adenoma/polyp). However, in this manuscript, some serrated lesions did not satisfy the criteria of these three categories and were defined as intermediate type. SSA/Ps are known to be closely associated with BRAF mutation and the CIMP(CpG island methylator phenotype); this suggests that SSA/Ps are precursors of CRCs(colorectal cancers), with MSI(microsatellite instability). Type II-O(Type II open-pit pattern)was specific to SSA/Ps with BRAF mutation and CIMP. However, molecular and clinical features of TSAs and intermediate type SSA/Ps remain unclear.
