Background: survival data regarding cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC) patients according to the type and extent of tumor-associated vascular thrombus are scarce. Objective: to test for survival differences in mRCC patients treated with CN according to the type and extent of tumor-associated vascular thrombus. Design, setting, and participants: within Surveillance, Epidemiology, and End Results Research Plus (2004–2017), we identified CN mRCC patients with renal vein (pT3a-TT) versus infradiaphragmatic inferior vena cava (IVC; pT3b) versus supradiaphragmatic IVC tumor thrombus/IVC invasion (pT3c). Outcome measurements and statistical analysis: overall survival (OS) was addressed in Kaplan-Meier and Cox regression analyses, in addition to 3-mo landmark analyses. Results and limitations: Of 2170 mRCC patients, 1880 (87%), 204 (9%), and 86 (4%) harbored pT3a-TT, pT3b, and pT3c, respectively. The respective median OS periods were 21, 23, and 12 mo (p < 0.001). In multivariable Cox regression models, pT3c stage, but not pT3b stage, was an independent predictor of higher overall mortality (hazard ratio [HR]: 1.37; 95% confidence interval [CI]: 1.09–1.73; p = 0.007), as well as in 6-mo landmark analyses (HR: 1.36; 95% CI: 1.02–1.80; p = 0.04). In the sensitivity analysis, relying on all pT3a patients, the predictor status of pT3c stage remained unchanged (HR: 1.37; 95% CI: 1.09–1.71; p = 0.007). Limitations have to be addressed regarding the sample size and the retrospective design of the current study. Conclusions: although overall mortality is significantly higher in pT3c mRCC patients than in their pT3b and pT3a-TT counterparts, these individuals may still expect 12-mo or better OS after CN versus virtually 2-yr OS in their pT3a and pT3b counterparts. Patient summary: in this study, we looked at the survival outcomes of metastatic renal cell carcinoma patients who presented with tumor thrombus at cytoreductive nephrectomy. Even though these patients with most advanced tumor thrombus stage demonstrated lower survival rates, the median overall survival was still 1 yr., Benedikt Hoeh certifies that all conflicts of interest, including specific financial interests and relationships and affiliations rel-evant to the subject matter or materials discussed in the manuscript (eg, employment/affiliation, grants or funding, consultancies, honoraria, stock ownership or options, expert testimony, royalties, or patents filed, received, or pending) , are the following: Benedikt Hoeh was awarded a scholarship by the Stiftung Giersch.

The effect of positive surgical margins (PSM) on cancer specific mortality (CSM) in high/very high-risk (HR/VHR) prostate cancer (PCa) with aggressive Gleason Grade Group (GGG) is unknown. We tested PSM effect on CSM in this setting, in addition to testing of radiotherapy (RT) benefit in PSM patients.We relied on Surveillance, Epidemiology, and End Results database (2010-2015), focusing on HR/VHR patients with exclusive GGG 4-5 at radical prostatectomy (RP). Kaplan-Meier plots and multivariable Cox regression models tested the relationship between PSM and CSM. Moreover, the effect of RT on CSM was explored in PSM patients.Of 3383 HR/VHR patients, 15.1% (n = 511) exhibited PSM. Patients with PSM harbored higher rates of GGG 5 (60.1% vs. 50.9%, p 0.001), pathologic tumor stage T3a (69.1% vs. 45.2%, p 0.001) and lymph node involvement (14.1% vs. 9.4%, p 0.001), relative to patients without PSM. PSM rates decreased over time (2010-2015) from 16.0% to 13.6%. Seven-year CSM-free survival rates were 91.6% versus 95.7% in patients with and without PSM, respectively. In multivariable Cox regression models, PSM was an independent predictor of CSM (hazard ratio = 1.6, p = 0.040) even after adjustment for age, prostate specific antigen, pathologic tumor stage and lymph node status. Finally, in PSM patients, RT delivery did not reduce CSM in either univariable or multivariable Cox regression models.In HR/VHR PCa patients with exclusive GGG 4-5, PSM at RP adversely affect survival. Moreover, RT has no protective effect on CSM. In consequence, lowest possible PSM rates are crucial in such patients.

Guidelines suggest less favorable cancer control outcomes for local tumor destruction in T1a renal cell carcinoma patients with tumor size 3.1-4 cm. We compared cancer-specific mortality between cryoablation vs heat-based thermal ablation in patients with tumor size 3.1-4 cm, as well as in patients with tumor size ≤3 cm.Within the Surveillance, Epidemiology, and End Results database (2004-2018), we identified patients with clinical T1a stage renal cell carcinoma treated with cryoablation or heat-based thermal ablation. After up to 2:1 ratio propensity score matching between patients treated with cryoablation vs heat-based thermal ablation, we addressed cancer-specific mortality relying on competing risks regression models, adjusted for other-cause mortality and other covariates (age, tumor size, tumor grade, and histological subtype).Of 1,468 assessable patients with tumor size 3.1-4 cm, 1,080 vs 388 were treated with cryoablation vs heat-based thermal ablation, respectively. After up to 2:1 propensity score matching that resulted in 757 cryoablations vs 388 heat-based thermal ablations, in multivariable competing risks regression models, heat-based thermal ablation was associated with higher cancer-specific mortality (HR:2.02,Our findings corroborated that in cT1a patients with tumor size 3.1-4 cm, cancer-specific mortality is twofold higher after heat-based thermal ablation vs cryoablation. Conversely, in patients with tumor size ≤3 cm either ablation technique is equally valid. These findings should be considered at clinical decision making and informed consent.

Patients were divided into two groups according to their exposure to Aspirin. We relied on multivariable linear and logistic regression models to test whether Aspirin administration was associated with lower PSA values at prostate biopsy, higher PCa diagnosis, and higher Gleason Grade Grouping (GGG) at biopsy.Results: Were identified 1059 patients, of whom 803 (76%) did not take Aspirin vs 256 (24%) were taking it. In multivariable log-linear regression analysis, Aspirin administration was associated with lower PSA levels (OR 0.83, 95% CI 0.71– 0.97, p = 0.01), after controlling for age, prostate volume, smoking history, associated inflammation at prostate biopsy, presence of PCa at biopsy, and GGG. In multivariable logistic regression analysis, Aspirin administration was not found to be a predictor of PCa at prostate biopsy (OR 1.40, 95% CI 0.82– 2.40, p = 0.21) after controlling for age, PSA, smoking history, prostate volume, findings at digital rectal examination and the number of biopsy cores. In patients with PCa at prostate biopsy (n = 516), Aspirin administration was found to predict higher GGG (OR 2.24, 95% CI 1.01– 4.87, p = 0.04).Conclusion: Aspirin administration was found to be a predictor of more aggressive GGG. These findings suggest that a lower PSA threshold should be considered in patients taking Aspirin, as, despite low PSA levels, they might harbour aggressive PCa.Keywords: prostate-specific antigen, aspirin, inflammation, prostate cancer, prostate biopsy

To assess the effect of event-free survival duration on cancer-specific mortality (CSM) after radical cystectomy (RC) in nonmetastatic muscle-invasive squamous cell carcinoma of the urinary bladder.RC patients treated for non-metastatic muscle-invasive squamous cell carcinoma of the urinary bladder were identified within the Surveillance, Epidemiology, and End Results database (2000-2018). Independent predictor status for CSM of T and N stage groupings (i.e., T2N0, T3N0, T4N0, and TanyN1-3) was tested in multivariable Cox-regression models. Conditional 5-year CSM-free estimates were assessed at baseline and at 4 specific event-free survival times (i.e. 6, 12, 18 and 24 months), within each of the 4 examined stage groups.Of 981 RC patients, 206 (21%), 416 (42%), 152 (16%), and 207 (21%) were T2N0, T3N0, T4N0, and TanyN1-3, respectively. In multivariable Cox-regression models T3N0 (HR 1.94), T4N0 (HR 5.22), and TanyN1-3 (HR 6.62) were independent predictors of CSM, relative to T2N0. In conditional survival analyses based on 24 months event-free status, survival estimates were: 89% for T2N0 vs. 76% at baseline (Δ = 13%), 84% for T3N0 vs. 58% at baseline (Δ = 26%), 69% for T4N0 vs. 25% at baseline (Δ = 44%), 69% for TanyN1-3 vs. 22% at baseline (Δ = 47%).Event-free status at 24 months of follow-up is associated with substantially higher CSM-free survival than when CSM-free survival is predicted at baseline. The magnitude of this effect is most pronounced in TanyN1-3 and T4N0 patients, intermediate in T3N0 and more modest, nonetheless important, in T2N0.

Improved cancer control with increasing surgical experience-the learning curve-was demonstrated for open and laparoscopic prostatectomy. In a prior single-center study, we found that this might not be the case for robot-assisted radical prostatectomy (RARP).To investigate the relationship between prior experience of a surgeon and biochemical recurrence (BCR) after RARP.We retrospectively analyzed the data of 8101 patients with prostate cancer treated with RARP by 46 surgeons at nine institutions between 2003 and 2021. Surgical experience was coded as the total number of robotic prostatectomies performed by the surgeon before the patient operation.We evaluated the relationship of prior surgeon experience with the probability of BCR adjusting for preoperative prostate-specific antigen, pathologic stage, grade, lymph-node involvement, and year of surgery.Overall, 1047 patients had BCR. The median follow-up for patients without BCR was 33 mo (interquartile range: 14, 61). After adjusting for case mix, the relationship between surgical experience and the risk of BCR after surgery was not statistically significant (p = 0.2). The 5-yr BCR-free survival rates for a patient treated by a surgeon with prior 10, 250, and 1000 procedures performed were, respectively, 82.0%, 82.7%, and 84.8% (absolute difference between 10 and 1000 prior procedures: 1.6% [95% confidence interval: 0.4%, 3.3%). Results were robust to a number of sensitivity analyses.These findings suggest that, as opposed to open and laparoscopic radical prostatectomy, surgeons performing RARP achieve adequate cancer control in the early phase of their career. Further research should explore why the learning curve for robotic surgery differs from prior findings for open and laparoscopic radical prostatectomy. We hypothesize that surgical education, including simulation training and the adoption of objective performance metrics, is an important mechanism for flattening the learning curve.We investigated the relationship between biochemical recurrence after robot-assisted radical prostatectomy and surgeon's experience. Surgeons at an early stage of their career had similar outcomes to those of more experienced surgeons, and we hypothesized that surgical education in robotics might be an important determinant of such a finding.

Objective: To evaluate the relationship between enlarged prostate, bulky median lobe (BML) or prior benign prostatic hyperplasia (BPH) surgery and perioperative functional, and oncological outcomes in high-risk (HR) prostate cancer (PCa) patients treated with Retzius-sparing robot-assisted radical prostatectomy (RS-RARP). Methods: 320 HR-PCa patients treated with RS-RARP between 2011 and 2020 at a single high-volume center. The relationship between prostate volume, BML, prior BPH surgery and perioperative outcomes, Clavien-Dindo (CD) grade >= 2 90-day postoperative complications, positive surgical margins (PSMs), and urinary continence (UC) recovery was evaluated respectively in multivariable linear, logistic and Cox regression models. Complications were collected according to the standardized methodology proposed by EAU guidelines. UC recovery was defined as the use of zero or one safety pad.Results: Overall, 5.9% and 5.6% had respectively a BML or prior BPH surgery. Median PV was 45 g (range: 14-300). The rate of focal and non-focal PSMs was 8.4% and 17.8%. 53% and 10.9% patients had immediate UC recovery and CD >= 2. The 1- and 2-yr UC recovery was 84 and 85%. PV (p = 0.03) and prior BPH surgery (p = 0.02) was associated with longer operative time. BML was independent predictor of time to bladder catheter removal (p = 0.001). PV was independent predictor of PSMs (OR: 1.02; p = 0.009). Prior BPH surgery was associated with lower UC recovery (HR: 0.5; p = 0.03). Conclusion: HR-PCa patients with enlarged prostate have higher risk of PSMs, while patients with prior BPH surgery have suboptimal UC recovery. These findings should help physicians for accurate preoperative counseling and to improve surgical planning in case of HR-PCa patients with challenging features.

Large-scale analyses addressing cancer-specific mortality (CSM) in T1a renal cell carcinoma (RCC) patients treated with local tumor destruction (LTD), relative to partial nephrectomy (PN), are scarce.To compare CSM after LTD versus PN.Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2018), we identified patients with clinical T1a stage RCC treated with LTD or PN.After 1:1 ratio propensity score matching (PSM) between patients treated with LTD versus PN, competing risks regression (CRR) models addressed CSM, after adjustment for other-cause mortality (OCM) and other covariates (age, tumor size, tumor grade, and histological subtype).Relative to the 35 984 PN patients, 5936 LTD patients were older and more frequently harbored unknown RCC histological subtype or unknown grade. After 1:1 PSM that resulted in 5352 LTD versus 5352 PN patients, the 10-yr CSM rate was 8.7% versus 5.5%. In multivariable CRR models, LTD was associated with higher CSM, relative to PN (hazard ratio [HR]: 1.58, p 0.001). Subgroup analyses revealed invariably higher CSM after LTD versus PN in patients with tumor size ≤3 cm (10-yr CSM 7.2% vs 5.3%, multivariable HR: 1.47, p 0.001) and in patients with tumor size 3.1-4 cm (10-yr CSM 11.4% vs 6.1%, multivariable HR: 1.72, p 0.001). Lack of information regarding earlier cancer controls, retreatment, tumor location within the kidney, and type of surgery represented limitations.In T1a RCC patients, LTD is invariably associated with higher CSM relative to PN, even after adjustment for OCM and all available patient and tumor characteristics, and regardless of tumor size considerations. However, the magnitude of CSM disadvantage was more pronounced in LTD patients with tumor size 3.1-4 cm than in those with tumor size ≤3 cm.In patients with small renal masses, we observed higher cancer-specific death rates for local tumor destruction (LTD) than for partial nephrectomy. The LTD disadvantage was more pronounced for patients with tumor size 3.1-4 cm, but was also present in those with tumor size ≤3 cm.

Systemic therapies (ST) improved contemporary survival rates, relative to historical in clear cell metastatic renal carcinoma (ccmRCC) patients. The magnitude of this improvement is unknown according to race/ethnicity.Within the SEER registry (2000-2017), ccmRCC patients were stratified according to race/ethnicity (Caucasian, Hispanic, African American, Asian) and historical (2000-2009) vs contemporary (2010-2017) years of diagnosis. Competing risks regression (CRR) with adjustment for other-cause mortality and Poisson smoothed cumulative incidence plots addressed cancer-specific mortality (CSM).Of 10,141 mRCC patients, 4316 (43%) vs 5825 (57%) were diagnosed in historical vs contemporary era. Of 4316 historical patients, 3203 (74%) vs 593 (14%) vs 293 (7%) vs 227 (5%) were Caucasian, Hispanic, African American and Asian. Of 5825 contemporary patients, 4124 (71%) vs 977 (17%) vs 362 (6%) vs 362 (6%) were Caucasian, Hispanic, African American and Asian. Between 2000 and 2017, ST rates ranged from 12 to 57% in Caucasians, 2 to 57% in Hispanics, 33 to 50% in African Americans, 17 to 70% in Asians and universally increased toward a plateau in 2010. In Caucasians, CSM decreased from 80 to 74% vs 79 to 74% in Hispanics vs 79 to 77% in African Americans, but not in Asians (67-73%). Nonetheless, these rates translated into independent predictor status of contemporary years of diagnosis in all race/ethnicity groups: CSM hazard ratios of 0.75, 0.75, 0.73 and 0.80 in, respectively, Caucasian, Hispanic, African American and Asian.In all race/ethnicity groups, contemporary ST rates increased and improved CSM rates have also been recorded.

Background: Retzius-sparing (RS) robot-assisted radical prostatectomy represents a valid surgical treatment option for prostate cancer (PCa) patients. However, the available evidence on the role of RS in high-risk (HR) PCa setting is sparse.& nbsp;Objective: To describe our RS technique for HR-PCa patients and to evaluate intra-, peri-, and postoperative oncological and functional outcomes.& nbsp;Design, setting, and participants: A total of 340 D'Amico HR-PCa patients under -went RS at a single high-volume centre between 2011 and 2020. Surgical procedure:& nbsp;Surgical procedures were performed by five experienced robotic surgeons.& nbsp;Measurements: Complications were collected according to the standardised methodology proposed by the European Association of Urology guidelines. Postoperative outcomes were evaluated in patients with complete follow-up data (n = 320). Biochemical recurrence (BCR) was defined as two consecutive prostate-specific antigen values of >= 0.2 ng/ml. Urinary continence (UC) recovery was defined as the use of zero or one safety pad. Kaplan-Meier and multivariable logistic and Cox regression models were performed.& nbsp;Results and limitations: Fourteen patients (4%) experienced intraoperative complications and 52 90-d complications occurred in 44 patients (14%), of whom 24 had Clavien-Dindo 3a/b. Final pathology reported 49% International Society of Urological Pathology (ISUP) grade 4-5, 55% > pT3a, and 28.8% positive surgical mar-gins (PSMs; 9.4% focal and 19.4% extended PSMs). The median follow-up was 47 mo. Overall, 35.3% and 1.3% harboured BCR and died from PCa. At 4 yr of follow-up, BCR-free survival and additional treatment-free survival were 63.6% and 56.6%, respectively. ISUP 4-5 at biopsy (odds ratio [OR]: 2.6), prostate volume (OR: 1.03), partial or full nerve sparing (OR: 1.9), and full bladder neck preservation (OR: 2.2) were independent predictors of PSMs. Pathological ISUP 4-5 (hazard ratio [HR]: 1.5) and PSMs (HR: 2.3) were independent predictors of BCR. Pathological ISUP 4-5 (HR: 1.5), PSMs (HR: 2.4), pT >= 3b (HR: 1.8), and pN >= 1 (HR: 1.8) were independent predictors of additional treatment. Immediate UC recovery was recorded in 53% patients. The 1-and 2-yr UC recovery and erectile function recovery were, respectively, 84% and 85%, and 43% and 50%.& nbsp;Conclusions: RS in HR-PCa patients allows optimal intra-, peri-, and postoperative outcomes. The RS approach should be considered a valid surgical treatment option for HR-PCa patients in expert hands.& nbsp;Patient summary: Relying on the largest cohort of high-risk prostate cancer patients treated with Retzius sparing (RS), we observed that the RS approach is safe and allows optimal cancer control, without significantly compromising functional outcomes.

Controlled contemporary analyses of mortality in metastatic collecting duct renal cell carcinoma (mcdRCC) are unavailable. We addressed this knowledge gap and tested rates of treatment and associated mortality in patients with mcdRCC.Within Surveillance, Epidemiology, and End Results database (2004-2018), we identified 155 mcdRCC patients. Kaplan-Meier plots and Cox proportional hazards regression models tested the effect of treatment (cytoreductive nephrectomy [CN] alone vs. systemic therapy [ST] alone vs. combination of both CN + ST) on overall mortality (OM).In the overall cohort (n = 155), 57 patients (37%) were treated with combination of both CN + ST, 46 (30%) underwent CN alone, 28 (18%) received ST alone, and 24 (15%) had none/unknown treatment. According to age categories (≤ 59 vs. 60-69 vs. ≥ 70 years), rates of combination of both CN + ST were 45% vs. 45% vs. 14%, respectively. CN alone was the most frequent type of treatment in patients aged ≥ 70 (50%). Median overall survival was 4.0 months for CN alone vs. 5.5 months for ST alone vs. 9.0 months for combination of both CN+ST. In multivariable Cox regression models, where CN alone was the referent, the use of ST alone and combination of both CN + ST were respectively associated with a HR of 0.74 (P = .3) and 0.43 (P.001), after adjustment for all covariates.In mcdRCC patients, concomitant use of CN and ST results in lowest mortality, followed by ST alone, and CN alone. In consequence combination of both CN + ST should be recommended whenever applicable.

Collecting duct carcinoma (CDC) is a rare renal malignancy. We relied on a large population-based cohort to address epidemiology, clinical characteristics, and treatment of CDC patients. We also tested survival in the overall cohort, as well as in stage-specific fashion.Within Surveillance, Epidemiology, and End Results (2004-2018) database, we identified 399 CDC patients. Based on Kaplan-Meier plots survival estimates, conditional survival rates were derived according to disease stage. Cox regression models tested for predictors of cancer specific mortality (CSM).Overall, 273 (68.4%) patients were male, 236 (59.2%) had T3-4 stages, 148 (37.1%) had lymph node invasion, and 156 (39.1%) had distant metastases at initial diagnosis. Nephrectomy alone was commonest in stage I-II (n = 91/99, 92%) and III (n = 94/116, 81%). Combination of both nephrectomy and systemic therapy was commonest in stage IV (n = 62/172, 36%). In the overall cohort, median cancer specific survival was 18 months. Provided a disease-free interval of 24 months, five-year Kaplan-Meier estimated survival at diagnosis increased from 74.2 to 91.0% in stage I-II, from 31.1 to 65.3% in stage III, and from 6.3 to 34.1% in stage IV. In multivariable Cox regression models addressing CSM, systemic therapy (Hazard Ratio [HR]: 0.47, P = 0.020), nephrectomy (HR: 0.37, P0.001) and combination of both (HR: 0.28, P0.001) exhibited a strong protective effect.Despite its highly aggressive phenotype and dismal survival, CDC is sensitive to nephrectomy and/or systemic therapy. Moreover, even for advanced stage, a more favorable prognosis can be achieved in patients, who benefit of disease-free interval after diagnosis and initial treatment.

We tested for other-cause mortality (OCM) differences according to race/ethnicity in metastatic renal cell carcinoma (mRCC). Such differences may affect treatment considerations.Within the Surveillance, Epidemiology, and End Results Research Plus repository (2000-2018), we identified clear cell (ccmRCC) and non-clear cell (non-ccmRCC) mRCC patients and stratified according to race/ethnicity: Caucasian vs. Hispanic vs. African American vs. Asian. Poisson smoothed cumulative incidence plots and competing risks regression (CRR) models addressing OCM, after adjustment for cancer-specific mortality , were fitted. Subsequently, multivariable logistic regression models tested access to cytoreductive nephrectomy (CNT) and systemic therapy (ST).Of 10,958 ccmRCC patients, 7,892 (72%), 1,743 (16%), 688 (6%), and 635 (6%) were Caucasian, Hispanic, African American, and Asian, respectively. Of 1,239 non-ccmRCC patients, 799 (64%), 106 (9%), 278 (22%), and 56 (5%) were Caucasian, Hispanic, African American, and Asian, respectively. In multivariable CRR models, OCM was higher in African Americans vs. Caucasians in ccmRCC (HR:1.55; CI:1.19-2.01; P0.001) and in non-ccmRCC (HR:1.54; CI:1.01-2.35; P = 0.04). In multivariable logistic regression models, African Americans with ccmRCC were less likely to undergo CNT (OR:0.72, CI:0.60-0.86; P0.001), but more likely to undergo ST (OR:1.34, CI:1.11-1.61; P = 0.002).In this retrospective analysis, African Americans with ccmRCC and non-ccmRCC exhibited higher OCM than Caucasians. Based on higher OCM, African Americans were less likely to undergo CNT, but more likely to benefit from ST.

To evaluate the feasibility of "in-office" TPFBx under local anesthesia (LA).We prospectively screened for eligibility data of 724 consecutive men undergoing either TPFBx (target and systematic cores) or TPSBx (systematic cores only) from September 2016 to June 2018 due to suspicion of prostate cancer (CaP), according to predefined exclusion criteria.We included 459 men (TPFBx n = 279 including n = 338 mpMRI lesions, Pi-RADS 4 in 63.6%; TPSBx n = 180). Median procedural time and maximum pain were 19 minutes and 5 numeric rating scale (NRS) points; pain was highest at the time of LA. Only 1 major complication occurred (Clavien 3a). Hematuria and hematospermia were frequent (72.6% and 54.2%). Vaso-vagal reactions and AUR were rare (0.7% and 0.4%). No cases of UTI and 1 case of fever were recorded. No significant changes in erectile and urinary functions were noted from baseline compared to 40 days after TPFBx (P = .86 and P = .89). In comparison with TPSBx the sole differences were pain during prostatic sampling (P = .03), duration of hematospermia (P.0001) and procedural time (P.001) all higher for TPFBx. Clinically significant (cs) CaP was detected in n = 150 (53.8%) patients in the TPFBx group (34.9%, 51.7%, and 75% of Pirads 3, 4, and 5, respectively). Addition of systematic cores detected n = 25 csCaP that were missed by targeted cores (17.4% of all csCaP).TPFBx under LA are feasible, yielding high tolerability, low complications, no impact on erectile and urinary function and good csCaP detection. Addition of systematic to targeted cores remains recommended. Further studies are needed to confirm our findings.
