Abstract

Idiopathic ulcerative colitis (IUC) patients have higher incidence of dysplasia and malignancy. Close follow-up with biopsy at regular interval is mandatory. The study was done to correlate incidence of atypical epithelium, goblet cell hyperplasia (GCH) and disease duration (DD) with Ki67, AgNOR and p53 expression in IUC with disease for 5 or more years. Ki67 and AgNOR are good indicators of cellular proliferation and p53 tumour suppressor protein is a marker for neoplastic cell. Of 130 cases studied, 40 cases showed atypical epithelium and were selected for further study. DD in these 40 cases ranged from 60 to 228 months. All had GCH and showed histological features of chronicity. Low-grade dysplasia (LGD) was seen in 15 cases, indefinite for dysplasia (ID) in 8 and inflammatory atypia in 17 cases. Disease duration showed no influence in the type of atypical epithelium. A positive staining of lining epithelium by Ki67 and p53 was not restricted to dysplasia. LGD and ID showed stronger p53 nuclear staining. AgNOR appeared to be a more sensitive marker than Ki67. GCH showed a positive correlation with DD and AgNOR index. p53 expression correlated positively with goblet cell hyperplasia. Conclusion- goblet cell hyperplasia could indicate presence of epithelial cell dysplasia.
