Significant Predictive Factors for Prognosis of Primary Upper Urinary Tract Cancer after Radical Nephroureterectomy in Taiwanese Patients
Accepted 17 January 2008, Published online 28 January 2008, pages 1127 - 1135
To follow up the long-term prognosis of patients who underwent nephroureterectomy for primary upper urinary tract (UUT) cancer and to evaluate the predictive factors of tumour recurrence and survival.
Between January 1990 and June 2005, 260 patients with primary UUT transitional cell carcinoma (TCC) underwent radical nephroureterectomy at our institution. The medical records of these patients were retrospectively reviewed. The clinical and histopathological data were analyzed to evaluate predictive factors.
The median follow-up time was 52 mo. In total, 89 patients (34.1%) developed subsequent bladder tumours. Predictive factors of bladder tumour recurrence were being male and having renal insufficiency. Local recurrence developed in 16 patients (6.2%); only the tumour stage was significantly associated with local recurrence. Metachronous contralateral UUT tumour was diagnosed in 12 patients (4.6%), with gender being the only predictive factor. Of the 260 patients, 167 (63.9%) were disease-free and alive at a median follow-up of 56.5 mo, and 45 (17.2%) died of urothelial cancer at a median period of 20 mo. Only the tumour stage was a prognostic factor to predict cancer-specific survival.
In patients with UUT-TCC after radical nephroureterectomy, tumour stage is the only prognostic factor for both local recurrence and cancer-specific survival. Male patients with renal insufficiency should be alerted to the possibility of bladder tumour recurrence. Because female patients were more likely to develop contralateral recurrences, renal ultrasonography, intravenous pyelography, or retrograde pyelography should be performed more frequently for female patients who live in the high-prevalence area.
