Introduction: In NCCN favorable intermediate-risk (FIR) prostate cancer (PCa) patients treated with radical prostatectomy (RP), we tested the effect of upstaging and upgrading on cancer-specific mortality (CSM).

Methods: Within the SEER database (2010-2021), upstaging (≥pT3a or pN1) and upgrading (ISUP ≥3) rates in FIR RP patients were tabulated. Kaplan-Meier (KM) plots and multivariable Cox-regression models (CRMs) were fitted.

Objective: Demographic changes will lead to higher proportions of metastatic hormone-sensitive (mHSPC) and castration resistant metastatic prostate cancer (mCRPC) patients with higher frailty index and multiple comorbidities.

Materials And Methods: We relied on an institutional tertiary-care database to explore the effect of frailty (Eastern Cooperative Oncology Group [ECOG]), as well as cardiovascular (CVD) and secondary malignancy (SecCa) comorbidities on overall survival (OS) and time to mCRPC in mHSPC and OS in mCRPC patients with Kaplan-Meyer estimates and Cox regression models.

Results: Of 802 mHSPC patients, 61% were ECOG0 vs.

To test whether the contemporary robot-assisted nephroureterectomy (RNU) is associated with more favorable in-hospital outcomes than historical RNU, relative to the same endpoints in open NU (ONU). Within the National Inpatient Sample (2008-2019), we identified RNU and ONU patients. Multivariable logistic and Poisson regression models were fitted.

Introduction: To test for cancer specific mortality (CSM) differences after either radical prostatectomy (RP) or radiotherapy (RT) in incidental prostate cancer (IPCa) patients.

Patients And Methods: Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2015), IPCa patients were identified. Cumulative incidence plots as well as competing risks regression (CRR) models were fitted to address CSM after adjustment for other-cause mortality (OCM).
