Abstract

Purpose

To assess the impact of the number of lymph nodes removed and of the template of dissection during radical cystectomy for bladder cancer on patients’ survival rates.

Materials and methods

We evaluated 282 consecutive patients who underwent radical cystectomy for muscle-invasive or high-grade superficial bladder cancer between 1995 and 2011. Exclusion criteria were incomplete follow-up data and neo-adjuvant or adjuvant treatments. Patients were divided into groups according to the most informative cut-point of number of lymph nodes retrieved and of the template of dissection. The cancer-specific survival rates were estimated by the Kaplan–Meier method. The univariate and multivariable forward-stepwise Cox proportional hazards regression were applied to analyze the survival outcomes.

Results

The mean (SD) follow-up was 59.2 ± 44.3 months, and the mean (SD) age of the entire cohort population was 68.3 ± 8.3 years. The cancer-specific survival rates were 58.7 and 47.7 % at 5 and 10 years, respectively. Considering both node-positive and node-negative patients, those with at least 14 LNs removed and those submitted to extended or super-extended PLND experienced significantly higher cancer-specific survival at both univariate and multivariable analysis.

Conclusions

Patients undergoing a more extended pelvic lymph node dissection, both in terms of number of LN removed and in terms of template of dissection, will experience a better cancer-specific survival. Our data support a potential role of lymphadenectomy on cancer outcome.
