OBJECTIVE: To identify the impact of tumour location on the disease recurrence and survival of patients who were treated surgically for upper urinary tract transitional cell carcinoma (UUT-TCC).
PATIENTS AND METHODS: A single-centre series of 189 consecutive patients who were treated surgically for UUT-TCC between January 1999 and December 2009 was evaluated. Patients who had previously undergone radical cystectomy, preoperative chemotherapy or contralateral UUT-TCC were excluded. In all, 133 patients were available for evaluation. Tumour location was categorized as renal pelvis or ureter based on the location of the dominant tumour. Recurrence-free probabilities and cancer-specific survival were estimated using the Kaplan-Meier method and Cox regression analyses.
RESULTS: The 5-year recurrence-free and cancer-specific survival estimates for the cohort in the present study were 66% and 62%, respectively. The 5-year bladder-only recurrence-free probability was 76%. Using multivariate analysis, only pT classification (hazard ratio, HR, 2.46; P = 0.04) and demographic characteristics (HR, 2.86 for areas of Balkan endemic nephropathy, vs non-Balkan endemic nephropathy areas; 95% confidence interval, 1.37-5.98; P = 0.005) were associated with disease recurrence. Tumour location was not associated with disease recurrence in any of the analyses. There was no difference in cancer-specific survival between renal pelvis and ureteral tumours (P = 0.476). Using multivariate analysis, pT classification (HR, 8.04; P = 0.001) and lymph node status (HR, 4.73; P = 0.01) were the only independent predictors associated with a worse cancer-specific survival.
CONCLUSION: Tumour location is unable to predict outcomes in a single-centre series of consecutive patients who were treated with radical nephroureterectomy for UUT-TCC.
