Abstract

OBJECTIVE We tested relationship between pelvic lymph node dissection (PLND) status at the time of radical prostatectomy (RP) and survival in prostate cancer (PCa) patients. METHODS Overall, 127,824 PCa patients treated with RP between 1988 and 2006 were included. Univariable and multivariable Cox regression analyses were used to evaluate the impact of PLND status (pN0 vs. pNx vs. pN1) on cancer-specific mortality (CSM) and overall mortality (OM) rates. RESULTS In pT2 patients, the 5-, 10-, and 15-year CSM rates were: 0.4%, 1.7%, and 3.9% for pN0, 0.6%, 2.5%, and 4.7% for pNx, 2.7%, 11.9%, and 20.6% for pN1 patients (all P0.05). CONCLUSIONS Patients with localized PCa treated with RP without a PLND (pNx) have less favorable survival rate than their counterparts that do not harbor lymph node invasion at PLND. However, the difference is modest (0.8% at 10 years). In consequence, the related costs and benefits of this procedure should be weighted carefully. In addition, the survival benefit of PLND was not observed in locally advanced PCa patients.
