Prognostic assessments in patients with upper tract urothelial carcinoma undergoing radical nephroureterectomy and systematic regional lymph node dissection.

OBJECTIVES

Systematic regional lymph node dissection (LND) combined with radical nephroureterectomy (RNU) has been reported to improve the outcomes of upper tract urothelial carcinoma (UTUC) patients. The objective of the present study was to assess the prognostic outcomes of UTUC patients undergoing systematic regional LND combined with RNU.

PATIENTS AND

METHODS

We conducted a retrospective evaluation of prognostic outcomes of 68 consecutive UTUC patients treated with RUN and systematic regional LND.

RESULTS

The median durations of recurrence-free survival (RFS) and overall survival (OS) were 45 and 166 months, respectively. Univariate analyses of several parameters showed that despite the lack of a significant predictor for RFS, the presence of lymph node metastasis correlated with poor OS.

CONCLUSION

These results suggest that comparatively favorable outcomes are achievable in UTUC patients by RNU and systematic regional LND; however, special attention is needed for patients with nodal involvement even after systematic regional LND due to the adverse impact of this factor on OS.
