One of the challenges for the surgical management of prostate cancer is the lymphatic spread of metastases. Lymph node metastases vary in size (micrometastases (<2 mm) or macrometastases (>2 mm)), and their interactions with the lymphatic environment differ (whether they are hypoxic or connected to blood flow). Thus, devising a universal...

We quantified the 2010-2014 rate of noninterventional treatment (NIT) management in active surveillance (AS) candidates according to 16 Surveillance, Epidemiology, and End Results (SEER) registries. The rate of NIT was markedly increased across all examined SEER registries within the study period. Nonetheless, important differences distinguish...

Purpose: Unfavorable prostate cancer (PCa) disease at final pathology affects at least 10 % of D'Amico low-risk patients. Thus, conservative therapies including active surveillance may be wrongfully applied. The purposes were to assess the rate of upstaging in a contemporary cohort of D'Amico low-risk PCa patients and to develop and externally...

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,...

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: 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: 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...

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: 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...

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...

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...

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...

Introduction: The effect of radical cystectomy (RC) on cancer-specific mortality (CSM) is unclear in non-metastatic sarcomatoid bladder cancer (SBC) patients. We aimed to test the benefit of RC in SBC, and to perform a direct comparison vs urothelial bladder cancer (UCB). Materials and methods: Within the Surveillance, Epidemiology, and End...

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...

Purpose: To test for differences in cancer-specific mortality (CSM) rates in Hispanic/Latino prostate cancer patients according to treatment type, radical prostatectomy (RP) vs external beam radiotherapy (EBRT). Methods: Within the Surveillance, Epidemiology, and End Results database (2010–2016), we identified 2290 NCCN (National Comprehensive...

Objective: To assess differences in the distribution of type and number of D'Amico high-risk criteria (DHRCs) according to race/ethnicity (R/E) and their effect on cancer-specific mortality (CSM) in prostate cancer (PCa) patients treated with external beam radiotherapy (RT). Methods: In the SEER database (2004–2016), we identified 31,002 PCa...

Introduction The role of chemotherapy in metastatic sarcomatoid bladder cancer (mSBC) is un-known. The current work aimed to test the effect of chemotherapy on overall survival (OS) in mSBC patients. Material and methods Using the Surveillance, Epidemiology and End Results database (2001–2018), we identified 110 mSBC patients of all T and N...

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...

Introduction: The survival benefit of inguinal lymph node dissection (ILND) vs no ILND in patients with squamous cell carcinoma of the penis (SCCP) and the absence of lymph node invasion is unclear. We addressed this uncertainty within the Surveillance, Epidemiology and End Results (SEER 2000–2018) database. Material and methods: We identified...

Purpose:We compared the use of 11C-choline and 68Ga-prostate specific membrane antigen in men undergoing salvage lymph node dissection for nodal recurrent prostate cancer.Materials and Methods:The study included 641 patients who experienced prostate specific antigen rise and nodal recurrence after radical prostatectomy and underwent salvage...
