Background: Previous cancer-specific mortality (CSM) analyses for different Gleason patterns in Gleason grade group (GGG) 5 cancer were limited by sample size. Objective: To test for differences in CSM according to biopsy GG 5 patterns (4 + 5 vs 5 + 4 vs 5 + 5) among patients undergoing radical prostatectomy (RP) or external beam radiation...

Background: Number of positive prostate biopsy cores represents a key determinant between high versus very high-risk prostate cancer (PCa). We performed a critical appraisal of the association between the number of positive prostate biopsy cores and CSM in high versus very high-risk PCa. Methods: Within Surveillance, Epidemiology, and End...

Background: To test for rates of other cause mortality (OCM) and cancer-specific mortality (CSM) in elderly prostate cancer (PCa) patients treated with the combination of radical prostatectomy (RP) and external beam radiation therapy (EBRT) versus RP alone, since elderly PCa patients may be over-treated. Methods: Within the Surveillance,...

Background: We relied on the most contemporary Surveillance, Epidemiology, and End Results (SEER) database and tested the hypothesis that chemotherapy may improve survival in metastatic urachal carcinoma (m-UraC). Material and Methods: Within the SEER database (2004–2016), we identified m-UraC patients aged ≥ 18 years. Propensity score matching...

Introduction Non-urothelial variant histology (VH), non-muscle invasive bladder cancer (NMIBC) has received little attention in contemporary urologic literature. Specifically, the effect of female sex on stage at presentation, as well as on cancer-specific mortality (CSM) have not been previously examined in VH NMIBC. Our aim was to test the...

Context: Three first line and three second-line clinical trials tested the effect of immunotherapy (IO) relative to standard chemotherapy (CT) on overall survival. However, network meta-analysis-based comparisons have not yet been presented. We addressed this void. Objective: To provide comparisons of overall survival (OS), progression-free...

Purpose: Our goal was to compare cancer-specific mortality (CSM) rates between radical prostatectomy (RP) vs external beam radiotherapy (EBRT) in National Comprehensive Cancer Network

Background: We hypothesized that Gleason Grade Group (GGG) IV patients treated with radical prostatectomy (RP) or external beam radiotherapy (EBRT) exhibit different cancer-specific mortality (CSM) rates according to underlying Gleason patterns (GP): 4 + 4 versus 3 + 5 versus 5 + 3. Materials and Methods: We identified all GGG IV patients...

Purpose: Data about optimal management of plasmacytoid (PCV) bladder cancer patients are extremely scarce and limited by sample size. We focused on PCV bladder cancer patients to explore the effect of radical cystectomy (RC) and chemotherapy in non-metastatic (T 2–4N0–3M0), as well as in metastatic (TanyNanyM1) subgroups. Methods: Using the...

Background: Some high-risk prostate cancer (PCa) patients may show more favorable Gleason pattern at radical prostatectomy (RP) than at biopsy. Objective: To test whether downgrading could be predicted accurately. Design, setting, and participants: Within the Surveillance, Epidemiology and End Results database (2010–2016), 6690 National...

Background: To test for differences in cancer-specific mortality (CSM) rates between radical prostatectomy (RP) vs external beam radiotherapy (EBRT) in National Comprehensive Cancer Network (NCCN) high-risk African American patients, as well as Johns Hopkins University (JHU) high-risk and very high-risk patients. Materials and methods: Within...

Aim: To compare cancer-specific mortality (CSM) rates between radical prostatectomy (RP) vs. external beam radiotherapy (RT) in patients with ductal carcinoma (DC) of the prostate. Materials and methods: Within the Surveillance, Epidemiology, and End Results (SEER) database (2004–2016), we identified 369 DC patients, of whom 303 (82%) vs. 66...

Introduction: Randomized clinical trials demonstrated improved overall survival in chemotherapy exposed metastatic prostate cancer patients. However, real-world data validating this effect with large scale epidemiological data sets are scarce and might not agree with trials. We tested this hypothesis. Materials and Methods: We identified de...

Aim: To compare overall mortality (OM), cancer-specific mortality (CSM), and other cause mortality (OCM) rates between radical prostatectomy (RP) versus radiotherapy (RT) in clinical node-positive (cN1) prostate cancer (PCa). Materials and Methods: Within Surveillance, Epidemiology, End Results (SEER) (2004–2016), we identified 4685 cN1 PCa...

Purpose: to compare observed overall survival vs age-adjusted lifetable (LT) derived life expectancy (LE) in metastatic urothelial bladder cancer (MBCa) patients according to race/ethnicity. Methods: We identified Caucasian, African American, Hispanic/Latino and Asian metastatic urothelial bladder cancer patients from 2004 to 2011 within the...

Purpose: To investigate pathological stage at radical prostatectomy (RP) using the "Partin tables" approach in NCCN high-risk (HR) prostate cancer (PCa) patients. Materials and Methods: Within the SEER 2010 to 2016 database, we identified 7,718 NCCN HR PCa patients. Cross-tabulation was used to illustrate the distribution of organ confined...
