PURPOSE: To characterize outcomes of patients with TaT1 urothelial carcinoma of the bladder stratified by the European Association of Urology (EAU) categories and to compare them with European Organization for Research and Treatment of Cancer (EORTC) risk groups to assess the rate and effect of reclassification. PATIENTS AND METHODS: A multi-institutional database of 5,122 patients with TaT1 urothelial carcinoma of the bladder who underwent transurethral resection of the bladder with or without adjuvant therapy at 8 institutions between 1996 and 2007. Multivariable Cox-regression analyses addressed factors associated with disease recurrence and progression. The net reclassification index was used to compare the performance of the EAU categories with the EORTC scoring system. RESULTS: Of 5,122 patients, 632 (12.3%), 2,302 (45.0%), and 2,188 (42.7%) were assigned to the low-, intermediate-, and high-risk EAU category, respectively. Within a median follow-up of 62 months (interquartile range: 27-97), 2,365 (46.2%) and 516 (10.1%) patients experienced disease recurrence and progression, respectively. In multivariable Cox-regression analyses, EAU intermediate- and high-risk categories were associated with a higher risk of disease recurrence (P<0.001) and progression (P<0.001) compared to low-risk patients. Application of the EAU categories reclassified 1,940 (37.9%) patients into a higher risk group for recurrence. Likewise, 602 (11.8%) patients were reclassified to a higher and 278 (5.4%) to a lower risk group for progression. The net reclassification index of the EAU risk stratification was 0.1% (95% CI: -3.1% to 3.2%) for recurrence and 10.1% (95% CI: -8.0% to 12.0%) for progression, respectively. CONCLUSIONS: Compared to EORTC risk stratification, the EAU categories reclassifies 37.9% patients into a higher risk group of recurrence and 11.8% into a higher risk of progression. However, the novel risk stratification assigns most patients to the same treatment as the more complex EORTC tables and can be regarded as an alternative tool for treatment decision-making.

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 Results database (2010-2016), 13,836 high versus 20,359 very high-risk PCa patients were identified. Discrimination according to 11 different positive prostate biopsy core cut-offs (≥2-≥12) were tested in Kaplan-Meier, cumulative incidence, and multivariable Cox and competing risks regression models. RESULTS: Among 11 tested positive prostate biopsy core cut-offs, more than or equal to 8 (high-risk vs. very high-risk: n = 18,986 vs. n = 15,209, median prostate-specific antigen [PSA]: 10.6 vs. 16.8 ng/ml, <.001) yielded optimal discrimination and was closely followed by the established more than or equal to 5 cut-off (high-risk vs. very high-risk: n = 13,836 vs. n = 20,359, median PSA: 16.5 vs. 11.1 ng/ml, p < .001). Stratification according to more than or equal to 8 positive prostate biopsy cores resulted in CSM rates of 4.1 versus 14.2% (delta: 10.1%, multivariable hazard ratio: 2.2, p < .001) and stratification according to more than or equal to 5 positive prostate biopsy cores with CSM rates of 3.7 versus 11.9% (delta: 8.2%, multivariable hazard ratio: 2.0, p < .001) in respectively high versus very high-risk PCa. CONCLUSIONS: The more than or equal to 8 positive prostate biopsy cores cutoff yielded optimal results. It was very closely followed by more than or equal to 5 positive prostate biopsy cores. In consequence, virtually the same endorsement may be made for either cutoff. However, more than or equal to 5 positive prostate biopsy cores cutoff, based on its existing wide implementation, might represent the optimal choice.

OBJECTIVE: To test the effect of race/ethnicity on histological subtype, stage at presentation, and cancer specific mortality (CSM) in urethral cancer patients. MATERIAL AND METHODS: Stratified analyses (Surveillance, Epidemiology and End Results [2004-2016]) tested the effect of race/ethnicity on histology and stage. Cumulative incidence-plots and multivariable competing-risks regression models (CRR), addressed CSM, after matching for TNM-stage, histology, age, and gender. RESULTS: Of 1,904 urethral cancer patients, 71% were Caucasian, 16% African American, 7% Hispanic and 5% other. African Americans were younger (66 years) than Caucasians (73 years) and Hispanics (74 years). In African Americans, adenocarcinoma (25%) and squamous cell carcinoma (SCC; 29%) were more frequent than in Caucasians (12% and 23%) or Hispanics (15% and 20%). African Americans with adenocarcinoma exhibited higher stage than other adenocarcinoma patients. In CRR, African Americans (35%) and Hispanics (29%) exhibited highest and second highest 3-year CSM, even after matching. After further multivariable adjustment of matched CRRs, CSM was higher in Hispanics (HR: 1.93, P= 0.03) and in African Americans (Hazard ratio 1.35, P= 0.07), relative to Caucasians. CONCLUSION: Race/ethnicity impacts important differences on urethral cancer patients. African American race/ethnicity predisposes to higher rate of SCC and adenocarcinoma. Moreover, African Americans are younger and present with higher stage at diagnoses. Finally, even after most detailed matching for stage, age, gender, and adjustment for treatment and systemic therapy and socioeconomic status, African Americans and Hispanics exhibit higher CSM than Caucasians.

Background: To test the effect of variant histology relative to urothelial histology on stage at presentation, cancer specific mortality (CSM), and overall mortality (OM) after chemotherapy use, in urethral cancer. Materials and Methods: Within the Surveillance, Epidemiology and End Results (2004-2016) database, we identified 1,907 primary variant histology urethral cancer patients. Kaplan-Meier plots, Cox regression analyses, cumulative incidence-plots, multivariable competing-risks regression models and propensity score matching for patient and tumor characteristics were used. Results: Of 1,907 eligible urethral cancer patients, urothelial histology affected 1,009 (52.9%) vs. squamous cell carcinoma (SCC) 455 (23.6%) vs. adenocarcinoma 278 (14.6%) vs. other histology 165 (8.7%) patients. Urothelial histological patients exhibited lower stages at presentation than SCC, adenocarcinoma or other histology patients. In urothelial histology patients, five-year CSM was 23.5% vs. 34.4% in SCC [Hazard Ratio (HR) 1.57] vs. 40.7% in adenocarcinoma (HR 1.69) vs. 43.4% in other histology (HR 1.99, p < 0.001). After matching in multivariate competing-risks regression models, variant histology exhibited 1.35-fold higher CSM than urothelial. Finally, in metastatic urethral cancer, lower OM was recorded after chemotherapy in general, including metastatic adenocarcinoma and other variant histology subtypes, except metastatic SCC. Conclusion: Adenocarcinoma, SCC and other histology subtypes affect fewer patients than urothelial histology. Presence of variant histology results in higher CSM. Finally, chemotherapy for metastatic urethral cancer improves survival in adenocarcinoma and other variant histology subtypes, but not in SCC.

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, Epidemiology and End Results database (2004-2016), cumulative incidence plots, after propensity score matching for cT-stage, cN-stage, prostate specific antigen, age and biopsy Gleason score, and multivariable competing risks regression models (socioeconomic status, pathological Gleason score) addressed OCM and CSM in patients (70-79, 70-74, and 75-79 years) treated with RP and EBRT versus RP alone. RESULTS: Of 18,126 eligible patients aged 70-79 years, 2520 (13.9%) underwent RP and EBRT versus 15,606 (86.1%) RP alone. After propensity score matching, 10-year OCM rates were respectively 27.9 versus 20.3% for RP and EBRT versus RP alone (p < .001), which resulted in a multivariable HR of 1.4 (p < .001). Moreover, 10-year CSM rates were respectively 13.4 versus 5.5% for RP and EBRT versus RP alone. In subgroup analyses separately addressing 70-74 year old and 75-79 years old PCa patients, 10-year OCM rates were 22.8 versus 16.2% and 39.5 versus 24.0% for respectively RP and EBRT versus RP alone patients (all p < .001). CONCLUSION: Elderly patients treated with RP and EBRT exhibited worrisome rates of OCM. These higher than expected OCM rates question the need for combination therapy (RP and EBRT) in elderly PCa patients and indicate the need for better patient selection, when combination therapy is contemplated.

BACKGROUND: We hypothesized that lymph node dissection (LND) at salvage radical prostatectomy may be associated with lower cancer-specific mortality (CSM) and we tested this hypothesis. METHODS: We relied on surveillance, epidemiology, and end results (2004-2016) to identify all salvage radical prostatectomy patients. Categorical, as well as univariate and multivariate Cox regression models tested the effect of LND (LND performed vs. not), as well as at its extent (log-transformed lymph node count) on CSM. RESULTS: Of 427 salvage radical prostatectomy patients, 120 (28.1%) underwent LND with a median lymph node count of 6 (interquartile range [IQR], 3-11). According to LND status, no significant or clinically meaningful differences were recorded in PSA at diagnosis, stage and biopsy Gleason score at diagnosis, except for age at prostate cancer diagnosis (LND performed 63 vs. 68 years LND not performed, p < .001). LND status (performed) was an independent predictor of lower CSM (hazard ratio [HR] 0.47; p = .03). Similarly, lymph node count (log transformed) also independently predicted lower CSM (HR: 0.60; p = .01). After the 7th removed lymph node, the effect of CSM became marginal. The effect of N-stage on CSM could not be tested due to insufficient number of observations. CONCLUSIONS: Salvage radical prostatectomy is rarely performed and LND at salvage radical prostatectomy is performed in a minority of patients. However, LND at salvage radical prostatectomy is associated with lower CSM. Moreover, LND extent also exerts a protective effect on CSM. These observations should be considered in salvage radical prostatectomy candidates.

PURPOSE: To test the effect of sex on histologic subtype, stage at presentation, treatment, and cancer-specific mortality (CSM) in urethral cancer. PATIENTS AND METHODS: We identified urethral cancer patients within the Surveillance, Epidemiology, and End Results (SEER) registry (2004-2016). After matching for tumor and patient characteristics, cumulative incidence plots and multivariable competing risks regression models, adjusted for other-cause mortality, tested CSM according to sex. RESULTS: Of 1645 eligible urethral cancer patients, 1073 (65%) were male. Urothelial histologic subtype was most frequent in male (59%) but not female (27%) subjects. Adenocarcinoma, squamous cell carcinoma, and other histologies were more frequent in female patients. Most male subjects harbored T1N0M0 (32%) stage disease, whereas most female subjects harbored T3-4N0M0 (29%) stage disease. In urothelial and adenocarcinoma histologic subtypes, African American female subjects were most prevalent (31 and 78%) versus whites (16 and 52%) versus Hispanics (27 and 74%). In T1N0M0 stage, single-mode surgical treatment was more frequent in male than female patients (respectively, 73% vs 59%). In T3-4 and/or N1-2 stage disease, multimodal therapy was more frequent in female than male (42% vs 37%) patients. In nonmetastatic urethral cancer (T1-4N0-2M0), after propensity score matching for stage, race, treatment, and age, cumulative incidence plots showed 5-year CSM of 36% and 25% in female and male patients, respectively, and after further multivariable adjustment resulted in 1.3-fold higher CSM in female as opposed to male patients (P = .07). CONCLUSION: Female patients with urethral cancer present with higher disease stage. Despite higher rates of multimodal therapy, and despite matching for stage disadvantage, female subjects with urethral cancer exhibited higher CSM.

PURPOSE: ABO blood type is an established prognostic factor for several malignancies but its role in bladder urothelial carcinoma is largely unknown. We determined whether ABO blood type is associated with the outcome of transurethral resection of nonmuscle invasive bladder urothelial carcinoma. MATERIALS AND METHODS: We retrospectively studied ABO blood types in 931 patients with primary nonmuscle invasive bladder urothelial carcinoma treated with transurethral bladder resection with or without intravesical instillation therapy. Disease recurrence and progression were analyzed with univariable and multivariable competing risks regression models. Median followup was 67 months. Discrimination was evaluated by the concordance index. RESULTS: The ABO blood type was O, A, B and AB in 414 (44.5%), 360 (38.7%), 103 (11.1%) and 54 patients (5.8%), respectively. ABO blood type was significantly associated with outcome on univariable and multivariable analysis. Overall, patients with blood type O had worse recurrence and progression rates than those with A (p = 0.015 and 0.031) or B (p = 0.004 and 0.075, respectively). The concordance index of multivariable base models increased after including ABO blood type. CONCLUSIONS: In patients with nonmuscle invasive bladder urothelial carcinoma the ABO blood type may predict the outcome. Those with blood type O showed the highest recurrence and progression rates. Including ABO blood type in multivariable models increases the accuracy of standard prognostic factors. Since the ABO blood type is available for most patients, it may represent an ideal adjunctive marker to predict recurrence and progression. The biological explanation and prognostic value of this finding must be further elucidated.

OBJECTIVE: To test for baseline prostate cancer characteristics and survival differences after salvage radical prostatectomy (SRP) across 18 Surveillance, Epidemiology and End Results (SEER) registries from 2004 to 2016. METHODS: We tabulated prostate-specific antigen (PSA), cT stage, age, and SRP rates across individual SEER registries. Kaplan-Meier and competing risks regression methodologies depicted cancer-specific mortality and other cause mortality. Finally, overall mortality was compared with predicted life expectancy. RESULTS: Overall, 428 SRP patients (2004-2016) were identified in the SEER database. Median follow-up duration was 74 months (interquartile range [IQR], 31-114). The median age at diagnosis was 68 years (IQR, 61-73 years) with a median PSA at diagnosis of 8.8 ng/mL (IQR, 5.4-18.6 ng/mL) and 10% cT3-4 stage (0%-23.8%). Variability existed across individual SEER registries regarding age, PSA, cT stage, and annual number of SRPs (0-17), as well as cumulative numbers of SRPs (7-73) between 2004 and 2016. At 10 years, cancer-specific mortality was 23.2% vs. other cause mortality 19.3%. Finally, SRP patients exhibited higher 10-year overall mortality (43.3%) than predicted by life tables (31.8%). CONCLUSION: SRP is rarely performed. In most SEER registries, SRP use is very occasional. More than 2 average annual SRPs were reported in only 5 of all registries. Nonetheless, across all registries, SRP patients showed marginal to moderate differences in PSA, cT stage, and age at diagnosis. However, at 10 years of follow-up, 1 of 5 SRP patients died of other causes and observed overall mortality was higher than expected (36%).

BACKGROUND: To analyze postoperative, in-hospital, complication rates in patients with organ transplantation before radical prostatectomy (RP). METHODS: From National Inpatient Sample (NIS) database (2000-2015) prostate cancer patients treated with RP were abstracted and stratified according to prior organ transplant versus nontransplant. Multivariable logistic regression models predicted in-hospital complications. RESULTS: Of all eligible 202,419 RP patients, 216 (0.1%) underwent RP after prior organ transplantation. Transplant RP patients exhibited higher proportions of Charlson comorbidity index ≥2 (13.0% vs. 3.0%), obesity (9.3% vs. 5.6%, both p < 0.05), versus to nontransplant RP. Of transplant RP patients, 96 underwent kidney (44.4%), 44 heart (20.4%), 40 liver (18.5%), 30 (13.9%) bone marrow, <11 lung (<5%), and <11 pancreatic (<5%) transplantation before RP. Within transplant RP patients, rates of lymph node dissection ranged from 37.5% (kidney transplant) to 60.0% (bone marrow transplant, p < 0.01) versus 51% in nontransplant patients. Regarding in-hospital complications, transplant patients more frequently exhibited, diabetic (31.5% vs. 11.6%, p < 0.001), major (7.9% vs. 2.9%) cardiac complications (3.2% vs. 1.2%, p = 0.01), and acute kidney failure (5.1% vs. 0.9%, p < 0.001), versus nontransplant RP. In multivariable logistic regression models, transplant RP patients were at higher risk of acute kidney failure (odds ratio [OR]: 4.83), diabetic (OR: 2.81), major (OR: 2.39), intraoperative (OR: 2.38), cardiac (OR: 2.16), transfusion (OR: 1.37), and overall complications (1.36, all p < 0.001). No in-hospital mortalities were recorded in transplant patients after RP. CONCLUSIONS: Of all transplants before RP, kidney ranks first. RP patients with prior transplantation have an increased risk of in-hospital complications. The highest risk, relative to nontransplant RP patients appears to acute kidney failure.
