Pathology and Clinical Significance of Inflammatory Bowel Disease-Associated Colorectal Dysplastic Lesions
2024, Gastroenterology Clinics of North AmericaTraditional serrated adenoma-like lesions in patients with inflammatory bowel disease: Serrated dysplasia in IBD
2020, Human PathologyCitation Excerpt :Abnormal p53 expression was present in 48% of these lesions and in 70% of those with high-grade serrated dysplasia. These results are in agreement with previous studies reporting p53 overexpression in 22% to 45% of all IBD-associated dysplastic lesions and up to 80% of high-grade lesions and IBD-associated CRCs [28,29]. In sporadic TSA, p53 overexpression has been reported in advanced lesions with superimposed dysplasia but was rare in ordinary TSAs [15,30,31].
Inflammatory Bowel Disease and Small Bowel Cancer Risk, Clinical Characteristics, and Histopathology: A Population-Based Study
2017, Clinical Gastroenterology and HepatologyThe molecular landscape of colitis-associated carcinogenesis
2017, Digestive and Liver DiseaseCitation Excerpt :In UC patients, telomere shortening has been documented in mucosa adjacent to dysplasia and cancer, and it has been detected more frequently in patients who subsequently develop cancer [57,58]. In contrast with the late involvement of TP53 dysregulation in sporadic colon carcinogenesis, seminal mutational profiling and LOH studies addressing IBD-associated oncogenesis have consistently pinpointed TP53 mutations and TP53 gene locus loss as early molecular changes already underway in intraepithelial neoplastic lesions [59–65]. TP53 mutations have also been observed in non-dysplastic UC-affected mucosa, further supporting the early involvement of TP53 [66].
