Cure8 research brief
Basal crypt dysplasia is easy to miss but linked to higher risk of advanced colorectal neoplasia in longstanding IBD. Improved recognition and use of p53 immunohistochemistry or complementary biomarkers could affect surveillance and diagnostic decisions.
Gastroenterologists; GI pathologists; clinicians managing IBD surveillance; researchers in IBD-associated cancer and biomarkers.
This is a pathology-focused review for clinicians and researchers.
It summarizes the histopathological definition and clinicopathological significance of BCD, the biological rationale for p53 alterations in colitis-associated carcinogenesis, and practical guidance on interpreting p53 immunostaining patterns (overexpression or complete absence) confined to basal crypts as supportive evidence for dysplasia.
The review also discusses limitations of p53 IHC, reproducibility issues in diagnosing BCD, and notes other biomarkers under study (SATB2) that may complement p53 in difficult cases.
This is a review article synthesizing existing studies and expert guidance. Full text access may require institutional subscription. p53 immunohistochemistry is an ancillary diagnostic tool with known limitations; the article also reviews reproducibility issues and emerging complementary biomarkers.

This study helps distinguish patterns of colorectal dysplasia seen in people without IBD from those seen in IBD, which may affect how pathologists and clinicians interpret biopsy findings and consider cancer risk and...
Sarcopenia is common in Crohn's disease and is linked to worse outcomes; a simple GNRI-based prediction tool could help identify at-risk patients without routine CT scanning.
The study points to serum protein panels and tissue expression of glypican-6 (GPC6) as potential tools to diagnose or predict intestinal strictures in Crohn disease, which could help detect fibrosis earlier and guide...
