Background/Aim:
To explore the prognostic value of lower urinary tract symptoms (LUTS) in patients with newly diagnosed regional lymph node-positive prostate cancer.
Patients And Methods:
The prognostic value of LUTS for progression-free (PFS) and overall (OS) survival, as well as the differential prognostic impact of radiotherapy by LUTS was investigated.
Results:
Univariate Cox-model analysis showed a statistically significantly increased hazard risk for PFS and OS for men with International Prostate Symptom Score (IPSS)≥19 and Overactive Bladder Symptom Score (OABSS) ≥8 at diagnosis. Patients with lower IPSS had a better PFS at 5 years (70.0% vs. 51.9%, p=0.027) and OS at 5 year (89.3% vs. 73.6%, p=0.016). Similarly, a lower OABSS was associated with greater PFS at 5 years (67.4% vs. 23.4%, p<0.001) and OS at 5 years (85.3% vs. 57.1%, p=0.012).
Conclusion:
IPSS and OABSS were prognostic for PFS and OS in patients with regional lymph node-metastatic prostate cancer.
