Transitional cell carcinoma of the kidney 25-year experience

Area of Science:

• Urologic oncology
• Nephrology
• Radiology

Background:

• Transitional cell carcinoma (TCC) of the kidney is a rare but significant diagnosis.
• Accurate staging and prognostic indicators are crucial for effective patient management.

Purpose of the Study:

• To review outcomes for kidney TCC patients treated over 25 years.
• To evaluate the relationship between pathologic stage, grade, excretory urography findings, and patient survival.
• To determine the optimal treatment strategy for kidney TCC.

Main Methods:

• Retrospective review of 70 patients with kidney TCC operated on at Barnes Hospital.
• Analysis of pathologic stage, tumor grade, and excretory urography findings.
• Correlation of these factors with patient survival rates.

Main Results:

• Excretory urography demonstrated a high accuracy in predicting pathologic stage and survival rates.
• Survival was occasionally more influenced by the status of concurrent bladder tumors than by the renal cancer.
• Tumor multiplicity was a significant factor in patient outcomes.

Conclusions:

• Excretory urography is a valuable tool for staging and predicting survival in kidney TCC.
• Total nephroureterectomy is recommended due to tumor multiplicity.
• The management of associated bladder tumors is critical for improving overall survival.
