    Abstract:
    BACKGROUND: The objective of the current study was to identify variables that were predictive of cancer-specific survival in patients with nonmetastatic transitional cell carcinoma of the upper urinary tract (UUT-TCC). METHODS: Clinical and pathologic data from 269 patients who underwent nephroureterectomy for UUT-TCC from 1989 to 2005 in 3 urologic European centers were collected retrospectively. Log-rank tests and Cox proportional-hazards regression models were used for univariate and multivariate analyses. RESULTS: Two hundred fifty patients underwent nephroureterectomy, and 19 patients underwent concomitant cystectomy for synchronous muscle-invasive bladder cancer. The median follow-up of the whole cohort was 34 months, and the median follow-up of the patients who remained alive and disease-free was 52 months. At follow-up, 57 cancer-related deaths (21.2%) were censored, and 169 patients (62.8%) were alive and disease-free. On univariate analysis, a history of previous bladder cancer, pathologic stage of the primary tumor and lymph nodes, tumor grade, the presence of lymphovascular invasion, tumor site, synchronous muscle-invasive bladder TCC, and tumor multifocality were associated with cancer-specific survival probabilities. On multivariate analysis, pathologic stage of the primary tumor and lymph nodes, tumor multifocality within the UUT, synchronous muscle-invasive bladder TCC, and a history of bladder TCC before the diagnosis of UUT-TCC were independent predictors of cancer-specific survival probabilities. CONCLUSIONS: In a multi-institutional dataset of patients who had undergone nephroureterectomy for UUT-TCC, the current results indicated that pathologic stage of the primary tumor and lymph nodes, a history of prior bladder TCC, the presence of synchronous muscle-invasive bladder cancer, and tumor multifocality within the UUT were independent predictors of cancer-specific survival probabilities.
