Differences in overall survival of penile cancer patients versus population-based controls.

PURPOSE: To assess whether 5-year overall survival (OS) of squamous cell carcinoma of the penis (SCCP) patients differs from age-matched male population-based controls. METHODS: We relied on the Surveillance Epidemiology and End Results database (2004-2018) to identify newly diagnosed (2004-2013) SCCP patients. For each case, we simulated an age-matched control (Monte Carlo simulation), relying on the Social Security Administration (SSA) Life Tables with 5 years of follow-up. We compared OS between SCCP patients and population-based controls in a stage-specific fashion. Smoothed cumulative incidence plots displayed cancer-specific mortality (CSM) versus other-cause mortality (OCM). RESULTS: Of 2282 SCCP patients, the stage distribution was as follows: stage I 976 (43%) versus stage II 826 (36%) versus stage III 302 (13%) versus stage IV 178 (8%). At 5 years, OS of SCCP patients versus age-matched population-based controls was as follows: stage I 63% versus 80% (Δ = 17%), stage II 50% versus 80% (Δ = 30%), stage III 39% versus 84% (Δ = 45%), stage IV 26% versus 87% (Δ = 61%). At 5 years, CSM versus OCM in SCCP patients according to stage was as follows: stage I 12% versus 24%, stage II 22% versus 28%, stage III 47% versus 14%, and stage IV 60% versus 14%. CONCLUSION: SCCP patients exhibit worse OS across all stages. The difference in OS at 5 years between SCCP and age-matched male population-based controls ranged from 17% to 61%. At 5 years, CSM accounted for 12% to 60% of all deaths, across all stages.

Added Value of Prostate-specific Antigen Density in Selecting Prostate Biopsy Candidates Among Men with Elevated Prostate-specific Antigen and PI-RADS ≥3 Lesions on Multiparametric Magnetic Resonance Imaging of the Prostate: A Systematic Assessment by PI-RADS Score.

BACKGROUND: A significant proportion of patients with positive multiparametric magnetic resonance imaging (mpMRI; Prostate Imaging-Reporting and Data System [PI-RADS] scores of 3-5) have negative biopsy results. OBJECTIVE: To systematically assess all prostate-specific antigen density (PSAD) values and identify an appropriate cutoff for identification of patients with positive mpMRI who could potentially avoid biopsy on the basis of their PI-RADS score. DESIGN, SETTING, AND PARTICIPANTS: The study included a cohort of 1341 patients with positive mpMRI who underwent combined targeted and systematic biopsies. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Multivariable logistic regression analysis (MVA) was used to assess the association between PSAD and the risk of clinically significant prostate cancer (csPCa, grade group ≥2) after adjusting for confounders. We used locally weighted scatterplot smoothing to explore csPCa risk according to PSAD and PI-RADS scores. PSAD utility was observed only for patients with PI-RADS 3 lesions, so we plotted the effect of each PSAD value as a cutoff for this subgroup in terms of biopsies saved, csPCa cases missed, and clinically insignificant PCa (ciPCa, grade group 1) cases not detected. RESULTS AND LIMITATIONS: Overall, 667 (50%) csPCa cases were identified. On MVA, PSAD independently predicted csPCa (odds ratio 1.57; p < 0.001). For PI-RADS ≥4 lesions, the csPCa risk was ≥40% regardless of PSAD. Conversely, among patients with PI-RADS 3 lesions, csPCa risk ranged from 0% to 60% according to PSAD values, and a PSAD cutoff of 0.10 ng/ml/cm3 corresponded to a threshold probability of 10% for csPCa. Using this PSAD cutoff for patients with PI-RADS 3 lesions would have saved 32% of biopsies, missed 7% of csPCa cases, and avoided detection of 34% of ciPCa cases. Limitations include selection bias and the high experience of the radiologists and urologists involved. CONCLUSIONS: Patients with PI-RADS ≥4 lesions should undergo prostate biopsy regardless of their PSAD, while PSAD should be used to stratify patients with PI-RADS 3 lesions. Using a threshold probability of 10% for csPCa, our data suggest that the appropriate strategy is to avoid biopsy in patients with PI-RADS 3 lesions and PSAD <0.10 ng/ml/cm3. Our results also provide information to help in tailoring an appropriate strategy for every patient with positive mpMRI findings. PATIENT SUMMARY: We investigated whether a cutoff value for PSAD (prostate-specific antigen density) could identify patients with suspicious prostate lesions on MRI (magnetic resonance imaging) who could avoid biopsy according to the PI-RADS score for their scan. We found that patients with PI-RADS ≥4 should undergo prostate biopsy regardless of their PSAD. A PSAD cutoff of 0.10 should be used to stratify patients with PI-RADS 3.

Differences in future life expectancy of testicular germ-cell tumor patients vs. age-matched male population-based controls.

BACKGROUND: It is unknown whether five-year overall survival (OS) differs and to what extent between testicular germ-cell tumor (TGCT) patients and age-matched male population-based controls. MATERIALS: We identified newly diagnosed (2004-2014) TGCT patients within Surveillance Epidemiology and End Results database 2004-2019. We compared OS between non-seminoma (NS-TGCT) and seminoma (S-TGCT) patients relative to age-matched male population-based controls based on Social Security Administration Life-Tables. Smoothed cumulative incidence plots displayed cancer-specific mortality (CSM) vs. other-cause mortality (OCM). RESULTS: Of all 20,935 TGCT patients, 43% had NS-TGCT and 57% had S-TGCT. Of NS-TGCT patients, 63% were stage I vs. 16% stage II vs. 21% stage III. Of S-TGCT patients, 86% were stage I vs. 8% were stage II vs. 6% stage III. Five-year OS differences between NS-TGCT patients vs age-matched male population-based controls were 97 vs. 99% (Δ = 2%) for stage I, 96 vs. 99% (Δ = 3%) for stage II, 76 vs 98% (Δ = 22%) for stage III. Five-year OS differences between S-TGCT patients vs age-matched male population-based controls were 97 vs. 98% (Δ = 1%) for stage I, 95 vs. 97% (Δ = 2%) for stage II, 87 vs. 98% (Δ = 11%) for stage III. OCM rates ranged from 1 to 3% in NS-TGCT patients and from 2 to 4% in S-TGCT patients. CONCLUSION: The OS difference between NS-TGCT patients vs. age-matched male population-based controls was invariably higher across all stages (2-22%) than for S-TGCT patients (1-11%). Reassuringly, OCM rates were marginal in stage I and stage II patients. Conversely, higher OCM rates were recorded in stage III patients.

Assessment of the VENUSS and GRANT Models for Individual Prediction of Cancer-specific Survival in Surgically Treated Nonmetastatic Papillary Renal Cell Carcinoma.

Background: Guidelines recommend VENUSS and GRANT models for the prediction of cancer control outcomes after nephrectomy for nonmetastatic papillary renal cell carcinoma (pRCC). Objective: To test the ability of VENUSS and GRANT models to predict 5-yr cancer-specific survival in a North American population. Design setting and participants: For this retrospective study, we identified 4184 patients with unilateral surgically treated nonmetastatic pRCC in the Surveillance, Epidemiology, and End Results database (2004-2019). Outcome measurements and statistical analysis: The original VENUSS and GRANT risk categories were applied to predict 5-yr cancer-specific survival. A cross-validation method was used to test the accuracy and calibration of the models and to conduct decision curve analyses for the study cohort. Results and limitations: The VENUSS and GRANT categories represented independent predictors of cancer-specific mortality. On cross-validation, the accuracy of the VENUSS and GRANT risk categories was 0.73 and 0.65, respectively. Both models showed good calibration and performed better than random predictions in decision curve analysis. Limitations include the retrospective nature of the study and the absence of a central pathological review. Conclusion: VENUSS risk categories fulfilled prognostic model criteria for predicting cancer-specific survival 5 yr after surgery in North American patients with nonmetastatic pRCC as recommended by guidelines. Conversely, GRANT risk categories did not. Thus, VENUSS risk categories represent an important tool for counseling, follow-up planning, and patient selection for appropriate adjuvant trials in pRCC. Patient summary: We tested the ability of two validated methods (VENUSS and GRANT) to predict death due to papillary kidney cancer in a North American population. The VENUSS risk categories showed good performance in predicting 5-year cancer-specific survival.

Adenocarcinoma of the Bladder: Assessment of Survival Advantage Associated With Radical Cystectomy and Comparison With Urothelial Bladder Cancer.

PURPOSE: To evaluate the association between radical cystectomy (RC) and cancer-specific mortality (CSM) in patients diagnosed with adenocarcinoma of the bladder (ACB). Moreover, to directly compare the survival advantage of RC between ACB vs. urothelial bladder cancer (UBC). MATERIALS AND METHODS: Non-metastatic muscle-invasive ACB and UBC patients were identified within Surveillance, Epidemiology, and End Results database (SEER 2000-2018). All analyses were stratified between RC vs. no-RC, in either organ-confined (OC: T2N0M0) or non-organ-confined (NOC: T3-4N0M0 or TanyN1-3M0) stages. Propensity score matching (PSM), cumulative incidence plots, competing risks regression (CRR) analyses, and 3 months' landmark analyses were performed. RESULTS: Overall, 1,005 ACB and 47,741 UBC patients were identified, of whom 475 (47%) and 19,499 (41%) were treated with RC, respectively. After PSM, comparison between RC vs. no-RC applied to 127 vs. 127 OC-ACB, 7,611 vs. 7,611 OC-UBC, 143 vs. 143 NOC-ACB, and 4,664 vs. 4,664 NOC-UBC patients. 36-month CSM rates in RC vs. no-RC patients were 14 vs. 44% in OC-ACB, 18 vs. 39% in OC-UBC, 49 vs. 66% in NOC-ACB, and 44 vs. 56% in NOC-UBC patients. In CRR analyses, the effect of RC on CSM yielded a hazard ratio of 0.37 in OC-ACB, of 0.45 in OC-UBC, of 0.65 in NOC-ACB and of 0.68 in NOC-UBC patients (all P values<0.001). Landmark analyses virtually perfectly replicated the results. CONCLUSIONS: In ACB, regardless of stage, RC is associated with lower CSM. The magnitude of this survival advantage was greater in ACB than in UBC, even after control for immortal time bias.

Differences in overall survival of T2N0M0 bladder cancer patients vs. population-based controls according to treatment modalities.

PURPOSE: It is unknown to what extent overall survival (OS) of organ-confined (T2N0M0) urothelial carcinoma of the urinary bladder (UCUB) patients differs from age- and sex-matched population-based controls, especially when treatment modalities such as radical cystectomy (RC), trimodal therapy (TMT), or radiotherapy (RT) are considered. METHODS: Relying on the Surveillance Epidemiology and End Results database (2004-2018), we identified newly diagnosed (2004-2013) T2N0M0 UCUB patients treated with either RC, TMT or RT. For each case, we simulated an age- and sex-matched control (Monte Carlo simulation), relying on Social Security Administration Life Tables with 5 years of follow-up, and compared OS with that of RC-, TMT-, and RT-treated cases. Additionally, we relied on smoothed cumulative incidence plots to display cancer-specific mortality (CSM) and other-cause mortality (OCM) rates for each treatment modality. RESULTS: Of 7153 T2N0M0 UCUB patients, 4336 (61%) underwent RC, 1810 (25%) TMT, and 1007 (14%) RT. At 5 years, OS rate in RC cases was 65% vs. 86% in population-based controls (Δ = 21%); in TMT cases, 32% vs. 74% in population-based controls (Δ = 42%); and in RT, 13% vs. 60% in population-based control (Δ = 47%). Five-year CSM rates were highest in RT (57%), followed by TMT (46%) and RC (24%). Five-year OCM rates were the highest in RT (30%), followed by TMT (22%) and RC (12%). CONCLUSION: OS of T2N0M0 UCUB patients is substantially less than that of age- and sex-matched population-based controls. The biggest difference affects RT, followed by TMT. A modest difference was recorded in RC and population-based controls.

Differences in overall survival between clear cell metastatic renal cell carcinoma patients versus population-based controls according to race/ethnicity in the United States.

PURPOSE: To quantify differences in five-year overall survival (OS) between clear cell metastatic renal cell carcinoma (ccmRCC) patients and age- and sex-matched population-based controls, especially when race/ethnicity is considered. METHODS: We relied on the Surveillance, Epidemiology and End Results database (2006-2016) to identify newly diagnosed (2006- 2011) ccmRCC patients of either Caucasian, Hispanic, African American, or Asian/Pacific Islander race/ethnicity. For each case, we simulated an age- and sex-matched control (Monte Carlo simulation), relying on Social Security Administration Life Tables with five-year follow-up. We compared OS between ccmRCC patients and controls. Multivariable Cox regression models tested for race/ethnicity effect on OS. RESULTS: Of 3067 ccmRCC patients, 2167 (71%) were Caucasians vs. 488 (16%) Hispanics vs. 216 (7%) African Americans and 196 (6%) Asians/Pacific Islanders. At five years, OS difference between ccmRCC patients vs. population-based controls was greatest in African Americans (11 vs. 94%, Δ = 84%), followed by Hispanics (16 vs. 94%, Δ = 77%), Caucasians (16 vs. 89%, Δ = 73%) and Asians/Pacific Islanders (19 vs. 88%, Δ = 70%). In multivariable Cox regression models, African Americans exhibited highest Hazard Ratio for death (HR 1.3, p= 0.003). CONCLUSION: Relative to Life Tables' derived age- and sex-matched controls, ccmRCC patients exhibit drastically worse OS, especially African Americans.

Standardising the Assessment of Patient-reported Outcome Measures in Localised Prostate Cancer. A Systematic Review.

CONTEXT: Prostate cancer (PCa) is the second most common cancer among men worldwide. Urinary, bowel, and sexual function, as well as hormonal symptoms and health-related quality of life (HRQoL), were prioritised by patients and professionals as part of a core outcome set for localised PCa regardless of treatment type. OBJECTIVE: To systematically review the measurement properties of patient-reported outcome measures (PROMs) used in localised PCa and recommend PROMs for use in routine practice and research settings. EVIDENCE ACQUISITION: The psychometric properties of PROMs measuring functional and HRQoL domains used in randomised controlled trials including patients with localised PCa were assessed according to the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) methodology. MEDLINE and Embase were searched to identify publications evaluating psychometric properties of the PROMs. The characteristics and methodological quality of the studies included were extracted, tabulated, and assessed according to the COSMIN criteria. EVIDENCE SYNTHESIS: Overall, 27 studies evaluating psychometric properties of the Expanded Prostate Cancer Index Composite (EPIC), University of California-Los Angeles Prostate Cancer Index (UCLA-PCI), European Organisation for Research and Treatment of Cancer (EORTC) quality of life core 30 (QLQ-C30) and prostate cancer 25 (QLQ-PR25) modules, International Index of Erectile Function (IIEF), and the 36-item (SF-36) and 12-item Short-Form health survey (SF-12) PROMs were identified and included in the systematic review. EPIC and EORTC QLQ-C30, a general module that assesses patients' physical, psychological, and social functions, were characterised by high internal consistency (Cronbach's α 0.46-0.96 and 0.68-0.94 respectively) but low content validity. EORTC QLQ-PR25, which is primarily designed to assess PCa-specific HRQoL, had moderate content validity and internal consistency (Cronbach's α 0.39-0.87). UCLA-PCI was characterised by moderate content validity and high internal consistency (Cronbach's α 0.21-0.94). However, it does not directly assess hormonal symptoms, whereas EORTC QLQ-PR25 does. CONCLUSION: The tools with the best evidence for psychometric properties and feasibility for use in routine practice and research settings to assess PROMs in patients with localised PCa were EORTC QLQ-C30 and QLQ-PR25. Since EORTC QLQ-C30 is a general module that does not directly assess PCa-specific issues, it should be adopted in conjunction with the QLQ-PR25 module. PATIENT SUMMARY: We reviewed and appraised the measurement properties of patient-reported outcome measure questionnaires used for patients with localised prostate cancer. We found good evidence to suggest that two questionnaires (EORTC QLQ-C30 and QLQ-PR25) can be used to measure urinary, bowel, and sexual functions and health-related quality of life.

Surgical Safety of Radical Cystectomy and Pelvic Lymph Node Dissection Following Neoadjuvant Pembrolizumab in Patients with Bladder Cancer: Prospective Assessment of Perioperative Outcomes from the PURE-01 Trial.

No data are available on the surgical safety of radical cystectomy (RC) and pelvic lymph node dissection (PLND) after the administration of checkpoint inhibitors. We aimed at reporting the first prospective rigorous assessment of perioperative outcomes after RC and extended PLND following neoadjuvant pembrolizumab in a contemporary cohort of patients with muscle-invasive bladder cancer (MIBC) enrolled in the PURE-01 trial. From February 2017 to June 2019, a total of 68 consecutive patients who received three courses of 200 mg pembrolizumab intravenously every 3 wk and were subsequently treated with either open or robot-assisted RC and PLND at a single high-volume tertiary referral center were identified. All men had prospectively collected data about intra- and postoperative outcomes. Postoperative complications were graded according to the Clavien-Dindo system. Perioperative data were prospectively and systematically collected during patient interviews at 90 d after surgery according to the European Association of Urology (EAU) Guidelines Panel recommendations on reporting and grading complications. Overall, 52 (77%) versus 16 (23%) patients underwent robot-assisted versus open RC, and 31 patients (46%) received an orthotopic neobladder. Median blood loss and length of stay were 150 ml and 12 d, respectively. Overall, 52 (77%), 47 (69%), and 22 (32%) patients experienced any-grade complications, grade ≥2 complications, and readmission at 90 d, respectively. High-grade complications (defined as Clavien-Dindo ≥3a) were observed in 23 patients (34%). The most frequent complications were fever (n = 35, 52%) and ileus (n = 21, 31%). None of the patients experienced perioperative mortality at 90 d. Our data represent the first prospective evidence supporting the surgical safety of RC and PLND in patients with N0M0 MIBC who received neoadjuvant immunotherapy with pembrolizumab. PATIENT SUMMARY: The current study represents the first prospective evidence supporting the surgical safety of radical cystectomy and pelvic lymph node dissection in patients with nonmetastatic bladder cancer who received neoadjuvant immunotherapy with pembrolizumab.
