transitional cell carcinoma grading

transitional cell carcinoma grading

Transitional cell carcinomas of the urothelium are graded histologically as follows:

• transitional cell papilloma
  • benign tumor, not a carcinoma but sometimes included in classification systems
• carcinoma in situ
  • do not penetrate the basement membrane
  • cells resemble those of grade II or III tumors
• grade I: low grade, rarely invade deeply or metastasize
• grade II: intermediate grade
• grade III: high grade, aggressively invasive with early metastases

It is important to note that grade is not as important in establishing prognosis as is stage .
