- Oncology
- Pathology
Context:
- Retrospective analysis of 189 colorectal polyp cases from 1985-1989.
- Inclusion of medical records, pathological diagnosis, and surgical management data.
- Evaluation of follow-up periods and their correlation with colorectal cancer development.
Purpose:
- To reclassify 189 histopathology slides based on current classification standards.
- To assess the premalignant potential of colorectal polyps.
- To analyze demographic and clinical features, including presenting symptoms and malignant transformation rates.
Summary:
- Predominance of male patients (69%) and increased incidence from the fifth decade (62%).
