RESUMO
BACKGROUND: Deterioration of renal function is associated with increased all-cause mortality. In renal masses larger than 4 cm, whether partial versus radical nephrectomy (PN vs. RN) might affect long-term functional outcomes is unknown. This study tested the association between PN versus RN and postoperative acute kidney injury (AKI), recovery of at least 90% of the preoperative estimated glomerular filtration rate (eGFR) at 1 year, upstaging of chronic kidney disease (CKD) one stage or more at 1 year, and eGFR decline of 45 ml/min/1.73 m2 or less at 1 year. METHODS: Data from 23 high-volume institutions were used. The study included only surgically treated patients with single, unilateral, localized, clinical T1b-2 renal masses. Multivariable logistic regression analyses were performed. RESULTS: Overall, 968 PN patients and 325 RN patients were identified. The rate of AKI was lower in the PN versus the RN patients (17% vs. 58%; p < 0.001). At 1 year after surgery, for the PN versus the RN patients, the rate for recovery of at least 90% of baseline eGFR was 51% versus 16%, the rate of CKD progression of ≥ 1 stage was 38% versus 65%, and the rate of eGFR decline of 45 ml/min/1.73 m2 or less was 10% versus 23% (all p < 0.001). Radical nephrectomy independently predicted AKI (odds ratio [OR], 7.61), 1-year ≥ 90% eGFR recovery (OR, 0.30), 1-year CKD upstaging (OR, 1.78), and 1-year eGFR decline of 45 ml/min/1.73 m2 or less (OR, 2.36) (all p ≤ 0.002). CONCLUSIONS: For cT1b-2 masses, RN portends worse immediate and 1-year functional outcomes. When technically feasible and oncologically safe, efforts should be made to spare the kidney in case of large renal masses to avoid the hazard of glomerular function loss-related mortality.

PURPOSE: 3D virtual models (3DVMs) are nowadays under scrutiny to improve partial nephrectomy (PN) outcomes. Five different Trifecta definitions have been proposed to optimize the framing of "success" in the PN field. Our aim is to analyze if the use of 3DVMs could impact the success rate of minimally invasive PN (mi-PN), according to the currently available definitions of Trifecta. MATERIALS AND METHODS: At our Institution 250 cT1-2N0M0 renal masses patients treated with mi-PN were prospectively enrolled. Inclusion criteria were the availability of contrast-enhanced CT, baseline and postoperative serum creatinine, and eGFR. These patients were then compared with a control group of 710 patients who underwent mi-PN with the same renal function assessments, but without 3DVMs. Multivariable logistic regression (MLR) models were used to predict the trifecta achievement according to the different trifecta definitions. RESULTS: Among the definitions, Trifecta rates ranged between 70.8% to 97.4% in the 3DVM group vs. 56.8% to 92.8% in the control group (all p values < 0.05). 3DVMs showed better postoperative outcomes in terms of ΔeGFR, ( - 16.6% vs. - 2.7%, p = 0.03), postoperative complications (15%, vs 22.9%, p = 0.002) and major complications (Clavien Dindo > 3, 2.8% vs 5.6%, p = 0.03). At MLR 3DVMs assistance independently predicted higher rates of successful PN across all the available definitions of Trifecta (OR: 2.7 p < 0.001, OR:2.0 p = 0.0008, OR:2.8 p = 0.02, OR 2.0 p = 0.003). CONCLUSIONS: The 3DVMs availability was found to be the constant predictive factor of successful PN, with a twofold higher probability of achieving Trifecta regardless of the different definitions available in Literature.

PURPOSE: To systematically review studies focused on screening programs for renal cell carcinoma (RCC) and provide an exhaustive overview on their clinical impact, potential benefits, and harms. METHODS: A systematic review of the recent English-language literature was conducted according to the European Association of Urology guidelines and the PRISMA statement recommendations (PROSPERO ID: CRD42021283136) using the MEDLINE, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases. Risk-of-bias assessment was performed according to the QUality In Prognosis Studies (QUIPS) tool. RESULTS: Overall, nine studies and one clinical trials were included. Eight studies reported results from RCC screening programs involving a total of 159 136 patients and four studies reported screening cost-analysis. The prevalence of RCC ranged between 0.02 and 0.22% and it was associated with the socio-demographic characteristics of the subjects; selection of the target population decreased, overall, the screening cost per diagnosis. CONCLUSIONS: Despite an increasing interest in RCC screening programs from patients and clinicians there is a relative lack of studies reporting the efficacy, cost-effectiveness, and the optimal modality for RCC screening. Targeting high-risk individuals and/or combining detection of RCC with other health checks represent pragmatic options to improve the cost-effectiveness and reduce the potential harms of RCC screening.

PURPOSE OF REVIEW: Small renal masses suspected to be malignant have little potential for metastasis and disease-related mortality. Surgery remains the standard care but represents overtreatment in many cases. Percutaneous ablative technique, especially thermal ablation has emerged as a valid alternative. RECENT FINDINGS: The increased availability of cross-sectional imaging has led to a large number of incidentally detected small renal masses (SRMs), many of which are of low grade and exhibit indolent behaviour. Since 1996, ablative techniques such as cryoablation, radiofrequency ablation, and microwave ablation have gained widespread acceptance for treatment of SRMs in patients who are not surgical candidates. In this review article, we provide an overview of each of the commonly used percutaneous ablative treatments for SRMs and summarize the current literature regarding the advantages and disadvantages of each technique. SUMMARY: Although partial nephrectomy (PN) represents the standard treatment of SRMs, Thermal ablation techniques have been increasingly used showing acceptable efficacy, low complication rate, and equivalent survival. Cryoablation seems to be superior to radiofrequency ablation in terms of local tumour control and retreatment rates. However, selection criteria for thermal ablation are still under refinement.

BACKGROUND: The aim of the study was to assess the effectiveness of the main classes of drugs used at reducing morbidity related to ureteric stents. SUMMARY: After establishing a priori protocol, a systematic electronic literature search was conducted in July 2019. The randomized clinical trials (RCTs) selection proceeded in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and was registered (PROSPERO ID 178130). The risk of bias and the quality assessment of the included RCTs were performed. Ureteral Stent Symptom Questionnaire (USSQ), International Prostate Symptom Score (IPSS), and quality of life (QoL) were pooled for meta-analysis. Mean difference and risk difference were calculated as appropriate for each outcome to determine the cumulative effect size. Fourteen RCTs were included in the analysis accounting for 2,842 patients. Alpha antagonist, antimuscarinic, and phosphodiesterase (PDE) inhibitors significatively reduced all indexes of the USSQ, the IPSS and QoL scores relative to placebo. Conversely, combination therapy (alpha antagonist plus antimuscarinic) showed in all indexes of the USSQ, IPSS, and QoL over alpha antagonist or antimuscarinic alone. On comparison with alpha blockers, PDE inhibitors were found to be equally effective for urinary symptoms, general health, and body pain parameters, but sexual health parameters improved significantly with PDE inhibitors. Finally, antimuscarinic resulted in higher decrease in all indexes of the USSQ, the IPSS, and QoL relative to alpha antagonist. KEY MESSAGE: Relative to placebo, alpha antagonist alone, antimuscarinics alone, and PDE inhibitors alone have beneficial effect in reducing stent-related symptoms. Furthermore, there are significant advantages of combination therapy compared with monotherapy. Finally, PDE inhibitors are comparable to alpha antagonist, and antimuscarinic seems to be more effective than alpha antagonist alone.

PURPOSE: To evaluate the role of 3D models on positive surgical margin rate (PSM) rate in patients who underwent robot-assisted radical prostatectomy (RARP) compared to a no-3D control group. Secondarily, we evaluated the postoperative functional and oncological outcomes. METHODS: Prospective study enrolling patients with localized prostate cancer (PCa) undergoing RARP with mp-MRI-based 3D model reconstruction, displayed in a cognitive or augmented-reality fashion, at our Centre from 01/2016 to 01/2020. A control no-3D group was extracted from the last two years of our Institutional RARP database. PSMr between the two groups was evaluated and multivariable linear regression (MLR) models were applied. Finally, Kaplan-Meier estimator was used to calculate biochemical recurrence at 12 months after the intervention. RESULTS: 160 patients were enrolled in the 3D Group, while 640 were selected for the Control Group. A more conservative NS approach was registered in the 3D Group (full NS 20.6% vs 12.7%; intermediate NS 38.1% vs 38.0%; standard NS 41.2% vs 49.2%; p = 0.02). 3D Group patients had lower PSM rates (25 vs. 35.1%, p = 0.01). At MLR models, the availability of 3D technology (p = 0.005) and the absence of extracapsular extension (ECE, p = 0.004) at mp-MRI were independent predictors of lower PSMr. Moreover, 3D model represented a significant protective factor for PSM in patients with ECE or pT3 disease. CONCLUSION: The availability of 3D models during the intervention allows to modulate the NS approach, limiting the occurrence of PSM, especially in patients with ECE at mp-MRI or pT3 PCa.

CONTEXT: The development of a tailored, patient-specific medical and surgical approach is becoming object of intense research. In kidney oncologic surgery, where a clear understanding of case-specific surgical anatomy is considered a key point to optimize the perioperative outcomes, such philosophy gained increasing importance. Recently, important advances in 3D virtual modeling technologies have fueled the interest for their application in the field of robotic minimally invasive surgery for kidney tumors. OBJECTIVE: To provide a synthesis of current applications of 3D virtual models for robot-assisted partial nephrectomy. EVIDENCE ACQUISITION: Medline, PubMed, the Cochrane Database, and Embase were screened for Literature regarding the use of 3D virtual models for robot-assisted partial nephrectomy (RAPN). EVIDENCE SYNTHESIS: The use of 3D virtual models for RAPN has been tested in different settings, including surgical indication and planning, intraoperative guidance, and training. Currently, several studies are available on the application of this technology for surgical planning, demonstrating impact on clinical outcomes such as renal function recovery, whilst experiences concerning their intraoperative application for navigation are still experimental. One of the latest innovations in this field is represented by the development of dedicated softwares able to automatically overlap the 3D virtual models to the real anatomy, to perform augmented reality procedures. CONCLUSIONS: The available Literature suggests a potentially crucial role of 3D virtual reconstructions during RAPN. Encouraging results concerning surgical planning and indication, intraoperative navigation, and surgical training are available. In the future, artificial intelligence may represent the key to further improve the 3D virtual modeling technology during RAPN.

BACKGROUND: Few data factually support the prognostic distinction between renal cell carcinomas (RCC) < 2 vs. 2.1-4 cm, in terms of cancer-specific mortality (CSM). We investigated CSM rates over time in <2 vs. 2.1-4 cm RCC, according to patient and tumor characteristics. METHODS: Within the Surveillance, Epidemiology and End Results (SEER) database, we focused on patients with T1aN0M0 RCC who underwent either radical or partial nephrectomy between 2000 and 2015. Temporal trends, Kaplan-Meier plots and multivariable Cox-regression analyses assessed CSM. RESULTS: Of 43,147 T1aN0M0 patients, 12,238 (28.4%) harbored RCC < 2 cm and 30,909 (71.6%) 2.1-4 cm RCC. The distribution of histological subtypes according to 2 cm cut-off was as follows: a). clear-cell G1/G2: 64.5 vs. 61.8%; b). papillary G1/G2 15.9 vs. 11.1%; c). clear-cell G3/G4: 9.9 vs. 16.1%; d). papillary G3/G4 4.9 vs. 5.4%; and e). chromophobe 4.9 vs. 5.2%. Five-year CSM rates were invariably lower in RCC < 2 cm than in 2.1-4 cm, for all histological subtypes and grade groups (a-e), even after additional multivariable adjustment for age and residual tumor size differences. 5-year CSM rates improved in more contemporary years, in both tumor size groups (< 2 vs. 2.1-4 cm), but to a greater extent in 2.1-4 cm renal masses. CONCLUSION: Our results validate the presence of prognostically more favorable CSM outcomes in RCC < 2 cm vs. 2.1-4 cm, across all histological subtypes and grades. Moreover, temporal improvements were also recorded in both <2 and 2.1-4 cm RCC groups, with more pronounced improvements in patients with 2.1-4 cm renal masses. However, prospective randomized trials are needed to further confirm our results.

BACKGROUND: The United States Census Bureau recommends distinguishing between "Asians" vs. "Native Hawaiians or Other Pacific Islanders" (NHOPI). We tested for prognostic differences according to this stratification in patients with prostate cancer (PCa) of all stages. METHODS: Descriptive statistics, time-trend analyses, Kaplan-Meier plots and multivariate Cox regression models were used to test for differences at diagnosis, as well as for cancer specific mortality (CSM) according to the Census Bureau's definition in either non-metastatic or metastatic patients vs. 1:4 propensity score (PS)-matched Caucasian controls, identified within the Surveillance, Epidemiology and End Results database (2004-2016). RESULTS: Of all 380,705 PCa patients, NHOPI accounted for 1877 (0.5%) vs. 23,343 (6.1%) remaining Asians vs. 93.4% Caucasians. NHOPI invariably harbored worse PCa characteristics at diagnosis. The rates of PSA ≥ 20 ng/ml, Gleason ≥ 8, T3/T4, N1- and M1 stages were highest for NHOPI, followed by Asians, followed by Caucasians (PSA ≥ 20: 18.4 vs. 14.8 vs. 10.2%, Gleason ≥ 8: 24.9 vs. 22.1, vs. 15.9%, T3/T4: 5.5 vs. 4.2 vs. 3.5%, N1: 4.4 vs. 2.8, vs. 2.7%, M1: 8.3 vs. 4.9 vs. 3.9%). Despite the worst PCa characteristics at diagnosis, NHOPI did not exhibit worse CSM than Caucasians. Moreover, despite worse PCa characteristics, Asians exhibited more favorable CSM than Caucasians in comparisons that focussed on non-metastatic and on metastatic patients. CONCLUSIONS: Our observations corroborate the validity of the distinction between NHOPI and Asian patients according to the Census Bureau's recommendation, since these two groups show differences in PSA, grade and stage characteristics at diagnosis in addition to exhibiting differences in CSM even after PS matching and multivariate adjustment.

BACKGROUND: To compare survival outcomes of metastatic patients harbouring either papillary (pRCC) or clear-cell (ccRCC) renal cell carcinoma in overall population and according to treatment modality. METHODS: Within the Surveillance, Epidemiology and End Results database (2006-2015), we identified 6800 patients (585 papillary and 6215 clear-cell) with metastatic RCC. Propensity-score (PS) matching, Kaplan-Meier plots and multivariable Cox-regression models (CRMs) were used. RESULTS: Overall, 585 (8.6%) patients harboured pRCC. Rates of nodal metastases were higher in patients with pRCC (49.7 vs. 23.3%; p < 0.001). Median overall survival (OS) was 13 vs. 18 months for pRCC vs. ccRCC patients. After multivariable adjustments, no difference in OS was recorded. Furthermore, after propensity-score matching, virtually the same results were recorded. Median OS of pRCC vs. ccRCC was 8 vs. 4 months for no treatment (NT), 11 vs. 12 months for targeted therapy alone (TT), 17 vs. 35 months for cytoreductive nephrectomy alone (CN) and 18 vs. 25 months for combination of CN with TT. CONCLUSIONS: Metastatic pRCC patients exhibit poor survival, regardless of treatment received. Moreover, pRCC patients are more likely to present nodal metastases, compared to ccRCC patients, as demonstrated by twofold higher rates of lymph node invasion at diagnosis. These observations indicate that papillary variant represents more prognostically unfavorable tumor histology, in the context of metastatic RCC.

PURPOSE: To test the effect of perioperative chemotherapy (CHT) on overall mortality (OM) and cancer-specific mortality (CSM) in patients with locally advanced or metastatic squamous cell carcinoma of the urinary bladder (SCC UB). METHODS: Within the Surveillance, Epidemiology and End Results database (1988-2016), we identified 1,018 SCC UB patients (664 T3-4aN0M0, 197 TanyN1-3M0 and 156 T4bN0-3 or M1), who underwent radical cystectomy with or without perioperative chemotherapy administration. Inverse probability of treatment-weighting (IPTW), Kaplan-Meier plots and Cox-regression models (CRMs) were used. RESULTS: CHT was administrated in 116 (17.5%) T3-4aN0M0, 77 (39.1%) TanyN1-3M0 and 47 (30.1%) T4bN0-3 or M1 patients. IPTW-adjusted 2-year cancer-specific survival (CSS) was 66.5 vs. 71.5% (p = 0.19), 60.9 vs. 29.5% (p < 0.001) and IPTW-adjusted 1-year CSS was 46.2 vs. 31.1% (p = 0.03) for CHT vs. no CHT administration in T3-4aN0M0, TanyN1-3M0 and T4bN0-3 or M1, respectively. In multivariable IPTW-adjusted CRMs, chemotherapy was an independent predictor of lower CSM in TanyN1-3M0 (HR 0.44) and in T4bN0-3 or M1 (HR 0.60), but not in T3-4aN0M0 (p = 0.6) patients. Virtually the same results were obtained on OM, as well as without IPTW-adjustment and after stratification according to age and gender. CONCLUSIONS: The use of perioperative CHT in patients with SCC UB confers survival benefit in the presence of T4b disease, lymph node or distant metastases. Conversely, patients with locally advanced disease but negative lymph node invasion do not benefit from its use. Pending higher quality data from prospective trials, these data should encourage the use of perioperative CHT in those high-risk patient groups.

PURPOSE: The urethro-vesical anastomosis represents one of the most challenging steps of robotic prostatectomy (RARP). To maximize postoperative management, we specifically designed our anastomosis quality score (AQS), based on the intraoperative characteristics of the urethra and bladder neck. METHODS: This is a prospective study, conducted from April 2019 to March 2020. All the patients were classified into three different AQS categories (low, intermediate, high) based on the quality of the anastomosis. The postoperative management was modulated accordingly. RESULTS: We enrolled 333 patients. According to AQS, no differences were recorded in intraoperative complications (p = 0.9). Median hospital stay and catheterization time were longer in AQS 1 group (p < 0.001). Additionally, the occurrence of postoperative complication was higher in AQS 1 category (p = 0.002) but, when focusing on the complications related to the quality of the anastomosis, no differences were found neither for acute urinary retention (p = 0.12) nor urine leakage (p = 0.11). Finally, concerning the continence recovery, no significant differences were found among the three groups for each time point. The highest potency recovery rate at one month of follow-up was recorded in AQS 3 category (p = 0. 03). CONCLUSION: The AQS proposed revealed to be a valid too to intraoperatively categorize patients who underwent RARP on the basis of the urethral and bladder neck features. The modulated postoperative management for each specific score category allowed to limit the occurrence of complications and to maximize the functional outcomes.

BACKGROUND: Our objective was to investigate age and sex-related discrepancies on distribution of metastases in patients with metastatic renal cell carcinoma (RCC). METHODS: Within the National Inpatient Sample database (2008-2015) we identified 9607 patients with metastatic RCC. Trend test and Chi-square test analyses were used to evaluate the relationship between age and site of metastases, according to sex. RESULTS: Of 9607 patients with metastatic RCC, 6344 (65.9%) were men and 3263 (34.1%) were women. Thoracic, abdominal, bone and brain metastases were present in 51.1 vs. 52.8%, 42.6 vs. 44.3%, 29.9 vs. 29.2% and 8.6 vs. 8.8% of men vs. women, respectively. Increasing age was associated with decreasing rates of thoracic (from 55.5 to 48.5%) and brain (from 8.6 to 5.8%) metastases in men and with decreasing rates of abdominal (from 48.3 to 39.6%), bone (from 32.6 to 24.9%) and brain (from 8.8 to 5.4%) metastases in women. (all p < 0.05). Rates of concomitant metastatic sites also decreased with increasing age, from 57.1 to 50.8% in men and from 54.1 to 50.2% in women. CONCLUSIONS: Important age and sex-related differences exist in the distribution of RCC metastases. The distribution of metastases is marginally different between sexes. Specifically, more advanced age is associated with lower rates of thoracic and brain metastases in men and with lower rates of abdominal, bone and brain metastases in women. Age and sex should be take into consideration into the staging management strategy, as well as into the follow-up strategy of patients with metastatic RCC.
RESUMO
PURPOSE: To test the effect of age on cancer-specific mortality (CSM) in most contemporary prostate cancer (PCa) patients of all stages and across all treatment modalities. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2016), we identified 579,369 PCa patients. Cumulative incidence plots and multivariable competing-risks regression analyses (MCR) were used. Subgroup analyses were performed according to ethnicity (African-Americans), clinical stage (T1-2N0M0, T3-4N0M0, TanyN1M0, and TanyNanyM1), as well as treatment modalities. RESULTS: Patient distribution was as follows: 142,338 (24.6%) < 60 years; 113,064 (19.5%) 60-64 years; 127,158 (21.9%) 65-69 years; 94,782 (16.4%) 70-74 years; and 102,027 (17.6%) ≥ 75 years. Older patients harbored worse tumor characteristics and more frequently received no local treatment. Overall, 10-year CSM rates were 4.8, 5.3, 5.9, 7.6, and 14.6%, respectively, in patients aged < 60, 60-64, 65-69, 70-74 ,and ≥ 75 years (p < 0.001). In MCR focusing on the overall cohort and T1-2N0M0 patients, older age independently predicted higher CSM, but not in T3-4N0-1M0-1 patients. CONCLUSIONS: Older age was associated with higher grade and stage and independently predicted higher CSM in T1-2N0M0 patients, but not in higher stages. Differences in diagnostics and therapeutics seem to affect elderly patients within T1-2N0M0 PCa and should be avoided if possible.

PURPOSE: To test the association between African-American race and overall mortality (OM) rates in patients with metastatic renal cell carcinoma (mRCC). METHODS: Within the Surveillance, Epidemiology, and End Results registry (2006-2015), we identified patients with clear cell (ccmRCC) and non-clear cell mRCC (non-ccmRCC). African-Americans, Caucasians, and Hispanics were identified. Stratification was made according to histology and treatments: (1) no treatment, (2) systemic therapy (ST), (3) cytoreductive nephrectomy (CNT), (4) CNT + ST. Kaplan-Meier plots and multivariable Cox regression analyses were used. RESULTS: Of ccmRCC patients, 410 (7%), 4353 (75%), and 1005 (17%) were African-American, Caucasian, and Hispanic, respectively. Of non-ccmRCC patients, 183 (25%), 479 (65%), and 77 (10%) were African-American, Caucasian, and Hispanic, respectively. In ccmRCC, African-Americans were associated with higher OM rates (HR 1.20; 95% CI 1.05-1.37). Conversely, in non-ccmRCC, African-Americans were associated with lower OM rates (HR 0.75; 95% CI 0.59-0.97). CONCLUSION: African-American race is associated with prolonged survival in non-ccmRCC, but it is also associated with lower survival rates in ccmRCC. The exception to these observations consisted of patients treated with combination of CNT + ST for either ccmRCC or non-ccmRCC.

OBJECTIVE: To summarize the clinical experiences with single-port (SP) robot-assisted radical prostatectomy (RARP) reported in the literature and to describe the peri-operative and short-term outcomes of this procedure. MATERIAL AND METHODS: A systematic review of the literature was performed in December 2019 using Medline (via PubMed), Embase (via Ovid), Cochrane databases, Scopus and Web of Science (PROSPERO registry number 164129). All studies that reported intra- and peri-operative data on SP-RARP were included. Cadaveric series and perineal or partial prostatectomy series were excluded. RESULTS: The pooled mean operating time, estimated blood loss, length of hospital stay and catheterization time were 190.55 min, 198.4 mL, 1.86 days and 8.21 days, respectively. The pooled mean number of lymph nodes removed was 8.33, and the pooled rate of positive surgical margins was 33%. The pooled minor complication rate was 15%. Only one urinary leakage and one major complication (transient ischaemic attack) were recorded. Regarding functional outcomes, pooled continence and potency rates at 12 weeks were 55% and 42%, respectively. CONCLUSIONS: The present analysis confirms that SP-RARP is safe and feasible. This novel robotic platform resulted in similar intra-operative and peri-operative outcomes to those obtained with the standard multiport da Vinci system. The advantages of single incision can be translated into a preservation of the patient's body image and self-esteem and cosmesis, which have a great impact on a patient's quality of life.

BACKGROUND: Conditional survival (CS) may reveal important differences in cancer-specific mortality (CSM) among patients with nonmetastatic renal cell carcinoma (nmRCC). This study assessed CS according to T and N stages in patients treated surgically for nmRCC. PATIENTS AND METHODS: Within the SEER database (2001-2015), all patients with nmRCC treated with either partial or radical nephrectomy were identified. CSM-free estimates according to T and N stage and substage groupings (pT1aN0-pT4N0 and pTanyN1) and multivariable Cox regression models with adjustment for Fuhrman grade and histologic subtype were assessed. RESULTS: According to T and N stage and substage groupings, the following patients were included in the study: 35,966 (46.2%) with pT1aN0 disease; 18,858 (24.2%) with pT1bN0; 5,977 (7.7%) with pT2aN0; 2,511 (3.2%) with pT2bN0; 11,839 (15.2%) with pT3aN0; 1,037 (1.3%) with pT3b-cN0; 402 (0.5%) with pT4N0; and 1,302 (1.7%) with pTanyN1. Conditional CSM-free survival estimates were 98.2% at 1 year versus 98.0% at 10 years of event-free follow-up for patients with pT1aN0 disease, relative to baseline. Conversely, pT4N0/pTanyN1 conditional CSM-free survival estimates were 55.8% at 1 year versus 77.9% at 8 years of event-free follow-up. Attrition due to mortality was highest in patients with pT4N0/pTanyN1 disease. In multivariable Cox regression analyses, T stage, tumor grade, and histologic subtype represented independent predictors, but no interactions were identified. CONCLUSIONS: Tumor stage and its substages represent extremely important determinants of prognosis after lengthy event-free follow-up. The recorded observations have critical importance for physicians regarding patient follow-up and counseling.

BACKGROUND: The NCCN Clinical Practice Guidelines in Oncology for Kidney Cancer recommend active surveillance as an option for initial management of T1a 0- to 2-cm renal lesions, in addition to partial nephrectomy, radical nephrectomy, and focal ablation. However, contemporary data regarding the distribution of patient and renal cell carcinoma characteristics within this special patient group are scarce. METHODS: Within the SEER database (2002-2016), 13,364 patients with T1aNanyMany 0- to 2-cm renal lesions treated with nephrectomy were identified. Data were tabulated according to histologic subtype, Fuhrman grade (FG1-2 vs FG3-4), age category, and sex. In addition, rates of synchronous metastases were quantified. RESULTS: Overall, clear-cell (69.3%), papillary (21.4%), chromophobe (6.9%), multilocular cystic (2.0%), sarcomatoid dedifferentiation (0.2%), and collecting-duct histologic subtypes (0.2%) were identified. Advanced age was associated with a lower rate of FG1-2 clear cell histologic subtype (70.8%-50.3%) but higher rates of FG1-2 papillary (11.1%-23.9%) and chromophobe histologic subtypes (6.2%-8.5%). Overall, 14.5% individuals harbored FG3-4 clear cell (9.8%) or FG3-4 papillary histologic subtypes (4.8%), and both were more prevalent in men. FG3-4 clear-cell and FG3-4 papillary histologic subtypes increased with age, more so in women than in men. The overall rate of synchronous metastases was 0.4% and ranged from 0 in the multilocular cystic subtype to 0.9% in the FG3-4 papillary histologic subtype, respectively, except for 13.8% in the sarcomatoid dedifferentiation histologic subtype. CONCLUSIONS: Most T1a 0- to 2-cm renal cell carcinoma represents the low-grade clear-cell or low-grade papillary histologic subtype, with an FG3-4 minority. Even in patients with the FG3-4 histologic subtype, rates of synchronous metastases are virtually zero.

BACKGROUND: Misclassification rates defined as upgrading, upstaging, and upgrading and/or upstaging have not been tested in contemporary Black patients relative to White patients who fulfilled criteria for very-low-risk, low-risk, or favorable intermediate-risk prostate cancer. This study aimed to address this void. METHODS: Within the SEER database (2010-2015), we focused on patients with very low, low, and favorable intermediate risk for prostate cancer who underwent radical prostatectomy and had available stage and grade information. Descriptive analyses, temporal trend analyses, and multivariate logistic regression analyses were used. RESULTS: Overall, 4,704 patients with very low risk (701 Black vs 4,003 White), 17,785 with low risk (2,696 Black vs 15,089 White), and 11,040 with favorable intermediate risk (1,693 Black vs 9,347 White) were identified. Rates of upgrading and/or upstaging in Black versus White patients were respectively 42.1% versus 37.7% (absolute Δ = +4.4%; P<.001) in those with very low risk, 48.6% versus 46.0% (absolute Δ = +2.6%; P<.001) in those with low risk, and 33.8% versus 35.3% (absolute Δ = -1.5%; P=.05) in those with favorable intermediate risk. CONCLUSIONS: Rates of misclassification were particularly elevated in patients with very low risk and low risk, regardless of race, and ranged from 33.8% to 48.6%. Recalibration of very-low-, low-, and, to a lesser extent, favorable intermediate-risk active surveillance criteria may be required. Finally, our data indicate that Black patients may be given the same consideration as White patients when active surveillance is an option. However, further validations should ideally follow.

PURPOSE: To test the conditional survival that examined the effect of event-free survival on cancer-specific mortality after primary tumour excision (PTE) in patients with squamous cell carcinoma of the penis (SCCP). MATERIALS AND METHODS: Within the SEER database (1998-2015), 2282 stage I-III SCCP patients were identified. Conditional survival estimates were used to calculate cancer-specific mortality (CSM) after event-free survival intervals of 1, 2, 3, and 5 years. Multivariable Cox regression models predicted CSM according to event-free survival. RESULTS: After PTE, 5-year CSM-free rate was 78.0% and increased to 84.6%, 88.1%, 92.0%, and 94.2% in patients who survived ≥ 1, ≥ 2, ≥ 3, and ≥ 5 years. After stratification according to tumour characteristics, 5-year CSM-free rates increased from 85.9 to 95.4%, 79.0 to 97.1%, 78.9 to 90.0%, and from 54.5 to 86.0% in those survived ≥ 5 years, respectively, in T1N0, T2N0, T3N0, and N1-2 patients. In multivariable analyses, T2N0 [hazard ratio (HR) 1.68; p value < 0.001], T3N0 (HR 1.94; p value 0.001), and N1-2 (HR 6.61; p value < 0.001) were independent predictors of higher CSM rate at baseline, relative to T1N0. A decrease in all HRs was assessed over time in patients who survived. Attrition due to CSM was highest in N1-2 cohort and lowest in T1N0. CONCLUSIONS: Conditional survival models showed a direct relationship between event-free survival duration and subsequent CSM in SCCP patients. Even patients with non-organ-confined disease may achieve survival probabilities similar to those with organ-confined disease after at least 5 years of event-free survival since PTE.
