The Role p53 Protein Expression in Urothelial Neoplasm

The urinary bladder had a line with transitional epithelium. Urothelial neoplasms are the majority among the bladder neoplasms. Urothelial neoplasms were more common in males than in females. Urothelial neoplasms usually occur in the elderly age group. The majority of the tumor size was more significant than 3 cm, and papillary type is majorly found among the tumors. The present study aimed to identify the grade and staging of the p53 in urothelial neoplasms.

The bladder carcinoma (54) cases from Department of Pathology, Sree Balaji Medical College and hospital (during September 2015 to September 2017) were analysed. The median age for bladder carcinoma in the present study was 66 years. The clinical parameter studied was the size of the lesion based on the cytoscopic or radiological findings (31- 33). Based on tumor size, lesions were classified into two groups, less than equal to 3cm and greater than 3cm, which was found to be 42% and 58%, respectively This study concludes that p53 is useful in differentiating benign and malignant neoplasms in morphologically difficult cases. Immunohistochemistry for p53 is useful adjunct to histomorphology.
