Anatomopathological Correlation Between The Clinical Tumor Stage And The Cystectomy Piece

Objectives: For a better staging of bladder tumors, we studied the characteristics and the clinical tumor stage in a series of patients and we compared them with the anatomopathological results of cystectomy. Materials and methods: The clinical data of 126 patients who had had radical cystectomy with ilio-obturator dissection for bladder cancer in our department were analyzed retrospectively. Results: Of the 126 cases studied, 86% were men (109 cases) and 14% women , the average age in our series is 60 years. There was a correlation in 48.4% of the cases. The differences between clinical and pathological stages were statistically significant, the agreement was moderate with a percentage of 1.5% of pT0 at the cystectomy site (P <0.005). We found the following results: 100% of the 2 T0 tumors were T2. 80% of the 31 T1 tumors were T1, while 7 were T2; 28.3% of T2 tumors were T2, 11.6% were superficial tumors; 77.7% of T3 tumors were T3; 100% of T4 tumors were T4. Pathological lymph node involvement was diagnosed in 77 patients (61.1%) while only 19.8% was diagnosed with an abdominopelvic CT scan (P <0.005). Conclusion: This study demonstrated the high risk of the presence of an increase or decrease in the local stage of the primary tumor and of lymph node involvement.
