Summary of "Association between Radical Prostatectomy and Survival in Men with Clinically Node-positive Prostate Cancer."

Evidence supporting radical prostatectomy (RP) for men with clinically node-positive (cN+) prostate cancer (PC) is limited. In a US national database, we identified 741 men with cN+ nonmetastatic PC diagnosed during 2000-2015 who underwent definitive local therapy with RP (n=78), radiotherapy (RT) with neoadjuvant androgen deprivation therapy (ADT) (n=193), or nondefinitive therapy with ADT alone (n=445) or observation (n=25). We compared PC-specific mortality (PCSM) and all-cause mortality (ACM) using multivariable Fine-Gray competing risk regression and Cox regression, respectively. Compared to nondefinitive therapy, RP was associated with significantly better PCSM (subdistribution hazard ratio [SHR] 0.32, 95% confidence interval [CI] 0.16-0.66; p=0.002) and ACM (HR 0.36, 95% CI 0.21-0.61; p<0.001). Compared to RT, RP was not associated with a significant difference in PCSM (SHR 0.47, 95% CI 0.19-1.17; p=0.1) or ACM (HR 0.88, 95% CI 0.46-1.70; p=0.71). These data suggest that RP is associated with favorable survival outcomes that appear to be superior to those for patients who did not receive definitive therapy and comparable to those for patients receiving definitive ADT/RT. Randomized trials of surgery with multimodal therapy are needed. PATIENT
SUMMARY:
We found that in clinically node-positive prostate cancer, radical prostatectomy was associated with a cancer-specific and overall survival benefit compared to nondefinitive therapy. Randomized clinical trials are required to determine the best treatment approach in this patient population.

The Effect of Lymph Node Dissection in Metastatic Prostate Cancer Patients Treated with Radical Prostatectomy: A Contemporary Analysis of Survival and Early Postoperative Outcomes.

Radical prostatectomy (RP) may occasionally be performed in patients with metastatic prostate cancer (mPCa). However, the role of lymph node dissection (LND) for such cases is unknown.
