The impact of tumor location and multifocality on prognosis for patients with upper tract urothelial carcinoma: a meta-analysis.

Abstract:

:There is lack of consensus regarding the prognostic significance of primary tumor location of upper tract urothelial carcinoma(UTUC). We performed a meta-analysis to evaluate the impact of primary tumor location on prognosis in patients with UTUC who had undergone radical nephroureterectomy(RNU). We included eligible studies that reported hazard ratios(HRs) estimates with 95% confidence intervals(CIs) for the association between tumor location and recurrence-free survival(RFS) and cancer-specific survival(CSS) of UTUC. The local advanced tumors(pT3/4) and nodal positive(pN+) tumors in patients stratified by tumor location were also estimated. The review contained 17 studies including a total of 12094 patients were identified. Although it was not significant in univariable analysis, meta-analysis demonstrated that ureteral tumors had a worse prognosis than renal pelvic tumors on RFS and CSS in multivariable analysis after adjusted for all covariates. Multifocal tumors also showed a significantly association with both disease progression and cancer-specific mortality in univariable and multivariable analyses. However, no statistically significant differences were found between renal pelvic and ureteral tumors in presentation of pT3/4 and pN+ tumors. Our meta-analysis indicated that ureteral and multifocal tumors are independent prognosticators of disease progression and cancer-specific survival in patients with UTUC treated with RNU.
