          Abstract

          Sessile serrated adenoma/polyps (SSA/Ps), which are precursor lesions of colorectal cancer (CRC) with BRAF mutation and the CpG island methylator phenotype (CIMP), develop cytological dysplasia (CD) during the progression of colorectal tumorigenesis. In the present study, we aimed to clarify the endoscopic and molecular signatures of SSA/Ps, with and without CD.
