- CONTEXT: Overall, 4-10% of patients with renal cell carcinoma (RCC) present with venous tumour thrombus. It is uncertain which surgical technique is best for these patients. Appraisal of outcomes with differing techniques would guide practice.OBJECTIVE: To systematically review relevant literature comparing the outcomes of different surgical therapies and approaches in treating vena caval thrombus (VCT) from nonmetastatic RCC.EVIDENCE ACQUISITION: Relevant databases (Medline, Embase, and the Cochrane Library) were searched to identify relevant comparative studies. Risk of bias and confounding assessments were performed. A narrative synthesis of the evidence was presented.EVIDENCE SYNTHESIS: The literature search identified 824 articles. Fourteen studies reporting on 2262 patients were included. No distinct surgical method was superior for the excision of VCT, although the method appeared to be dependent on tumour thrombus level. Minimal access techniques appeared to have better perioperative and recovery outcomes than traditional median sternotomy, but the impact on oncologic outcomes is unknown. Preoperative renal artery embolisation did not offer any oncologic benefits and instead resulted in significantly worse perioperative and recovery outcomes, including possibly higher perioperative mortality. The comparison of cardiopulmonary bypass versus no cardiopulmonary bypass showed no differences in oncologic outcomes. Overall, there were high risks of bias and confounding.CONCLUSIONS: The evidence base, although derived from retrospective case series and complemented by expert opinion, suggests that patients with nonmetastatic RCC and VCT and acceptable performance status should be considered for surgical intervention. Despite a robust review, the findings were associated with uncertainty due to the poor quality of primary studies available. The most efficacious surgical technique remains unclear.PATIENT SUMMARY: We examined the literature on the benefits of surgery to remove kidney cancers that have spread to neighbouring veins. The results suggest such surgery, although challenging and associated with high risk of complications, appears to be feasible and effective and should be contemplated for suitable patients if possible; however, many uncertainties remain due to the poor quality of the data.

Limitations of Available Studies Prevent Reliable Comparison Between Tumour Ablation and Partial Nephrectomy for Patients with Localised Renal Masses : A Systematic Review from the European Association of Urology Renal Cell Cancer Guideline Panel
- 2020

Forskningsöversikt (refereegranskat)abstract
- The European Association of Urology (EAU) Renal Cell Carcinoma (RCC) Guideline Panel performed a protocol-driven systematic review (SR) on thermal ablation (TA) compared with partial nephrectomy (PN) for T1N0M0 renal masses, in order to provide evidence to support its recommendations. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed, and only comparative studies published between 2000 and 2019 were included. Twenty-six nonrandomised comparative studies were included, recruiting a total of 167 80 patients. Risk of bias (RoB) assessment revealed high or uncertain RoB across all studies, with the vast majority being retrospective, observational studies with poorly matched controls and short follow-up. Limited data showed TA to be safe, but its long-term oncological effectiveness compared with PN remains uncertain. A quality assessment of pre-existing SRs (n = 11) on the topic, using AMSTAR, revealed that all SRs had low confidence rating, with all but two SRs being rated critically low. In conclusion, the current data are inadequate to make any strong and clear conclusions regarding the clinical effectiveness of TA for treating T1N0M0 renal masses compared with PN. Therefore, TA may be cautiously considered an alternative to PN for T1N0M0 renal masses, but patients must be counselled carefully regarding the prevailing uncertainties. We recommend specific steps to improve the evidence base based on robust primary and secondary studies.Patient summary: In this report, we looked at the literature to determine the effectiveness of thermoablation (TA) in the treatment of small kidney tumours compared with surgical removal. We found that TA could cautiously be offered as an option due to many remaining uncertainties regarding its effectiveness.

- Recent randomised trials have demonstrated a survival benefit for a front-line ipilimumab and nivolumab combination therapy, and pembrolizumab and axitinib combination therapy in metastatic clear-cell renal cell carcinoma. The European Association of Urology Guidelines Panel has updated its recommendations based on these studies. Patient summary: Pembrolizumab plus axitinib is a new standard of care for patients diagnosed with kidney cancer spread outside the kidney and who did not receive any prior treatment for their cancer (treatment naïve). This applies to all risk groups as determined by the International Metastatic Renal Cell Carcinoma Database Consortium criteria.

Sources of Frustration Among Patients Diagnosed With Renal Cell Carcinoma
- 2019

-
Tidskriftsartikel (refereegranskat)abstract
- Despite numerous therapeutic advances in renal cell carcinoma (RCC), little is known about patients' perspectives on cancer care. An international survey was conducted to identify points of frustration associated with cancer care reported by patients with RCC. Data were obtained from an online survey, conducted from April 1 to June 15, 2017, through social media and patient networking platforms. This survey obtained baseline demographic, clinicopathologic, and treatment-related information. Open-ended questions accessed sources of frustration in cancer-related care and patients' suggestions for amelioration. Responses were categorized and reviewed by independent reviewers. A qualitative analysis was performed and the Kruskal-Wallis test was used to define associations between baseline characteristics and sources of frustration. Among 450 patients surveyed, 71.5% reported sources of frustration, classified as either emotional (48.4%) or practical (23.1%). The most common were fear of recurrence/progression (15.8%), distrust of their cancer care system (12.9%), and lack of appropriate information (9.8%). Female gender and non-clear cell histology were associated with both types of frustration, and older age was linked to practical sources of frustration. Patients suggested solutions included greater compassion among health care practitioners (20.7%), better access to information (15.1%) and research to improve their chances of being cured (14.7%). Sources of frustration related to emotional and practical causes were identified amongst patients with RCC. Certain demographic and clinical characteristics were associated with more sources of frustration. This study provides the first characterization of specific ways to improve the patient experience by addressing common frustrations.

- Cytoreductive nephrectomy (CN) has been the standard of care in patients with metastatic clear-cell renal cancer who present with the tumour in place. The CARMENA trial compared systemic therapy alone with CN followed by systemic therapy. This article outlines the new guidelines based on these data.Patient summary: The CARMENA trial demonstrates that immediate cytoreductive nephrectomy should no longer be considered the standard of care in patients diagnosed with intermediate and poor risk metastatic renal cell carcinoma when medical treatment is required. However, the psychological burden poor risk patients experience hearing that removal of their primary tumour will not be beneficial, should be carefully considered.

Updated European Association of Urology Guidelines Regarding Adjuvant Therapy for Renal Cell Carcinoma
- 2017

- The European Association of Urology Renal Cell Carcinoma (RCC) guidelines panel updated their recommendation on adjuvant therapy in unfavourable, clinically nonmetastatic RCC following the recently reported results of a second randomised controlled phase 3 trial comparing 1-yr sunitinib to placebo for high-risk RCC after nephrectomy (S-TRAC). On the basis of conflicting results from the two available studies, the panel rated the quality of the evidence, the harm-to-benefit ratio, patient preferences, and costs. Finally, the panel, including representatives from a patient advocate group (International Kidney Cancer Coalition) voted and reached a consensus to not recommend adjuvant therapy with sunitinib for patients with high-risk RCC after nephrectomy. Patient summary: In two studies, sunitinib was given for 1 yr and compared to no active treatment (placebo) in patients who had their kidney tumour removed and who had a high risk of cancer coming back after surgery. Although one study demonstrated that 1 yr of sunitinib therapy resulted in a 1.2-yr longer time before the disease recurred, the other study did not show a benefit and it has not been shown that patients live longer. Despite having been diagnosed with high-risk disease, many patients remain without recurrence, and the side effects of sunitinib are high. Therefore, the panel members, including patient representatives, do not recommend sunitinib after tumour removal in these patients.

Novel Liquid Biomarkers and Innovative Imaging for Kidney Cancer Diagnosis : What Can Be Implemented in Our Practice Today? A Systematic Review of the Literature
- 2021
-
Ingår i: European Urology Oncology. - : Elsevier. - 2588-9311. ; 4:1, s. 22-41
-
Forskningsöversikt (refereegranskat)abstract
- CONTEXT: The epidemiological signature of renal cell carcinoma (RCC) during the past decades is explained by overdetection and overtreatment of indolent cancers; furthermore, a non-negligible proportion of patients undergoing surgery for suspected RCC harbour benign renal tumours. As the gold standard for RCC diagnosis remains histopathological analysis of surgical or biopsy specimens, implementation of noninvasive diagnostic strategies to discriminate between benign and malignant renal masses is an urgent unmet need. OBJECTIVE: To systematically review novel liquid biomarkers and imaging modalities for RCC diagnosis. EVIDENCE ACQUISITION: 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: CRD42020190773) using the MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, and ClinicalTrials.gov databases. Risk-of-bias assessment was performed according to the QUADAS 2 tool. EVIDENCE SYNTHESIS: Overall, 15 studies (six on biomarkers and nine on imaging) and eight clinical trials were included. None of the biomarkers or imaging modalities has been validated or shown to have a distinct clinical value for RCC. Specific combinations of urinary cell-free and exosomal miRNAs, urinary miR-15a, and specific panels of urinary metabolites assessed by metabolomics appear promising. In addition, machine/deep learning algorithms and radiomics applied to cross-sectional images may have potential to improve RCC diagnosis. Most studies are limited by the retrospective design, size, and lack of external validation. CONCLUSIONS: Liquid biomarkers or imaging modalities are not ready for integration in the clinic and further well-designed studies must validate preliminary findings and explore utility in clinical decision-making. PATIENT SUMMARY: We provide a comprehensive overview of the currently available biomarkers (measured in blood or urine) and novel imaging tests (other than conventional imaging) to discriminate kidney cancer from benign renal masses in a noninvasive fashion. None of the biomarkers or imaging modalities studied was validated or added clinical value; therefore, none of them can be implemented in the clinic. However, these approaches appear to be promising for improving the diagnosis of kidney cancer in the future.

Tidskriftsartikel (refereegranskat)abstract
- Objective: Modality and frequency of image-based renal cell carcinoma (R.C.C.) follow-up strategies are based on risk of recurrence. Using the R.E.C.U.R.-database, frequency of imaging was studied in regard to prognostic risk groups. Furthermore, it was investigated whether imaging modality utilized in contemporary follow-up were associated with outcome after detection of recurrence. Moreover, outcome was compared based on whether the assessment of potential curability was a pre-defined set of criteria's (per-protocol) or stated by the investigator. Materials and methods: Consecutive non-metastatic R.C.C. patients (n = 1,612) treated with curative intent at 12 institutes across eight European countries between 2006 and 2011 were included. Leibovich or U.I.S.S. risk group, recurrence characteristics, imaging modality, frequency and survival were recorded. Primary endpoints were overall survival (O.S.) after detection of recurrence and frequency of features associated with favourable outcome (non-symptomatic recurrences and detection within the follow-up-programme). Results: Recurrence occurred in 336 patients. Within low, intermediate and high risk for recurrence groups, the frequency of follow-up imaging was highest in the early phase of follow-up and decreased significantly over time (p < 0.001). However, neither the image modality for detection nor >= 50% cross-sectional imaging during follow-up were associated with improved O.S. after recurrence. Differences between per protocol and investigator based assessment of curability did not translate into differences in O.S. Conclusions: As expected, the frequency of imaging was highest during early follow-up. Cross-sectional imaging use for detection of recurrences following surgery for localized R.C.C. did not improve O.S. post-recurrence. Prospective studies are needed to determine the value of imaging in follow-up.

Intensive Imaging-based Follow-up of Surgically Treated Localised Renal Cell Carcinoma Does Not Improve Post-recurrence Survival : Results from a European Multicentre Database (RECUR)
- 2019

Tidskriftsartikel (refereegranskat)abstract
- The optimal follow-up (FU) strategy for patients treated for localised renal cell carcinoma (RCC) remains unclear. Using the RECUR database, we studied imaging intensity utilised in contemporary FU to evaluate its association with outcome after detection of disease recurrence. Consecutive patients with nonmetastatic RCC (n = 1612) treated with curative intent at 12 institutes across eight European countries between 2006 and 2011 were included. Recurrence occurred in 336 patients. Cross-sectional (computed tomography, magnetic resonance imaging) and conventional (chest X-ray, ultrasound) methods were used in 47% and 53%, respectively. More intensive FU imaging (more than twofold) than recommended by the European Association of Urology (EAU) was not associated with improved overall survival (OS) after recurrence. Overall, per patient treated for recurrence remaining alive with no evidence of disease, the number of FU images needed was 542, and 697 for high-risk patients. The study results suggest that use of more imaging during FU than that recommended in the 2017 EAU guidelines is unlikely to improve OS after recurrence. Prospective studies are needed to design optimal FU strategies for the future. Patient summary: After curative treatment for localised kidney cancer, follow-up is necessary to detect any recurrence. This study illustrates that increasing the imaging frequency during follow-up, even to double the number of follow-up imaging procedures recommended by the European Association of Urology guidelines, does not translate into improved survival for those with recurrence. After curative treatment for localised kidney cancer, a more intensive follow-up regimen than that recommended in the 2017 European Association of Urology guidelines did not improve overall survival among those experiencing recurrence, irrespective of the risk of recurrence. This suggests that an increase in follow-up imaging frequency is not cost-efficient. Prospective studies to identify more optimal follow-up strategies are needed.

- Local treatment of metastases such as metastasectomy or radiotherapy remains controversial in the treatment of metastatic renal cell carcinoma. To investigate the benefits and harms of various local treatments, we did a systematic review of all types of comparative studies on local treatment of metastases from renal cell carcinoma in any organ. Interventions included metastasectomy, radiotherapy modalities, and no local treatment. The results suggest that patients treated with complete metastasectomy have better survival and symptom control (including pain relief in bone metastases) than those treated with either incomplete or no metastasectomy. Nevertheless, the available evidence was marred by high risks of bias and confounding across all studies. Although the findings presented here should be interpreted with caution, they and the identified gaps in knowledge should provide guidance for clinicians and researchers, and directions for further research.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Optimal follow-up (FU) strategy to detect potentially curable (PC) recurrences after treatment of localised clear cell renal cell carcinoma (ccRCC) is unclear. This study retrospectively analysed a large international database to determine recurrence patterns and overall survival (OS), as part of a wider project to issue recommendations on FU protocols.OBJECTIVE: To analyse associations between RCC recurrences in patients with ccRCC, their risk group stratifications, treatments, and subsequent outcomes.DESIGN, SETTING, AND PARTICIPANTS: Nonmetastatic ccRCC patients treated with curative intent between 1 January 2006 and 31 December 2011, with at least 4 yr of FU, were included. Patient, tumour and recurrence characteristics, Leibovich score, and management and survival data were recorded. Isolated local, solitary, and oligometastatic (three or fewer lesions at a single site) recurrences were considered PC, while all others were probably incurable (PI).INTERVENTION: Primarily curative surgical treatment of ccRCC while at recurrence detection metastasectomy, systemic therapy, best supportive care, or observation.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Incidence, time to recurrence (TTR), and OS were measured. Competing risk analysis, Kaplan-Meier, and Cox regression models were used.RESULTS AND LIMITATION: Of 1265 patients with ccRCC, 286 had a recurrence, with 131 being PC and 155 PI. Five-year cumulative risks of recurrence for low- (n=53), intermediate- (n=105), and high-risk (n=128) patients were, respectively, 7.2%, 23.2%, and 61.6%, of whom 52.8%, 37.1%, and 30.5% were PC, respectively. Median TTR was 25.0 for PC patients versus 17.3 mo for PI patients (p=0.004). Median OS was longer in PC compared with that in PI patients (p<0.001). Competing risk analysis showed highest risk of ccRCC-related death in younger and high-risk patients. Limitations were no data on comorbidities, retrospective cohort, and insufficient data excluding 12% of cohort.CONCLUSIONS: Low-risk group recurrences are rare and develop later. Treatment of recurrences with curative intent is disappointing, especially in high-risk patients. An age- and risk score-dependent FU approach is suggested.PATIENT SUMMARY: We analysed data from eight European countries, and found that the incidence of the kidney cancer recurrence and patient survival correlated with clinical factors known to predict cancer recurrence reliably and age. We conclude that these factors should be used to design follow-up strategies.

- Context While vascular endothelial growth factor-targeted therapy and mammalian target of rapamycin inhibition are effective strategies in treating clear cell renal cell carcinoma (ccRCC), the most effective therapeutic approach for patients with non-clear cell RCC (non-ccRCC) is unknown. Objective To systematically review relevant literature comparing the oncological outcomes and adverse events of different systemic therapies for patients with metastatic non-ccRCC. Evidence acquisition Relevant databases including MEDLINE, Embase, and the Cochrane Library were searched up to March 24, 2016. Only comparative studies were included. Risk of bias and confounding assessments were performed. A meta-analysis was planned for and only performed if methodologically appropriate; otherwise, a narrative synthesis was undertaken. Evidence synthesis The literature search identified 812 potential titles and abstracts. Five randomized controlled trials, recruiting a total of 365 patients, were included. Three studies compared sunitinib against everolimus, one of which reported the results for non-ccRCC as a subgroup rather than as an entire randomized cohort. Individually, the studies showed a trend towards favoring sunitinib in terms of overall survival and progression-free survival (PFS; Everolimus versus Sunitinib in Patients with Metastatic Non-clear Cell Renal Cell Carcinoma hazard ratio [HR]: 1.41, 80% confidence interval [CI] 1.03–1.92 and 1.41, 95% CI: 0.88–2.27, Evaluation in Metastatic Non-clear Cell Renal Cell Carcinoma HR: 1.16, 95% CI: 0.67–2.01, Efficacy and Safety Comparison of RAD001 Versus Sunitinib in the First-line and Second-line Treatment of Patients with Metastatic Renal Cell Carcinoma HR: 1.5, 95% CI: 0.9–2.8), but this trend did not reach statistical significance in any study. Meta-analysis was performed on two studies which solely recruited patients with non-ccRCC reporting on PFS, the results of which were inconclusive (HR: 1.30, 95% CI: 0.91–1.86). Sunitinib was associated with more Grade 3–4 adverse events than everolimus, although this was not statistically significant. Conclusions This systematic review and meta-analysis represent a robust summary of the evidence base for systemic treatment of metastatic non-ccRCC. The results show a trend towards favoring vascular endothelial growth factor-targeted therapy for PFS and overall survival compared with mammalian target of rapamycin inhibitors, although statistical significance was not reached. The relative benefits and harms of these treatments remain uncertain. Further research, either in the form of an individual patient data meta-analysis involving all relevant trials, or a randomized controlled trial with sufficient power to detect potential differences between treatments, is needed. Patient summary We examined the literature to determine the most effective treatments for advanced kidney cancer patients whose tumors are not of the clear cell subtype. The results suggest that a drug called sunitinib might be more effective than everolimus, but the statistics supporting this statement are not yet entirely reliable. Further research is required to clarify this unmet medical need.

Forskningsöversikt (refereegranskat)abstract
- Context: Little is known about the natural history of sporadic angiomyolipomas (AMLs); there is uncertainty regarding the indications of treatment and treatment options. Objective: To evaluate the indications, effectiveness, harms, and follow-up of different management modalities for sporadic AML to provide guidance for clinical practice. Evidence acquisition: A systematic review of the literature was undertaken, incorporating Medline, Embase, and the Cochrane Library (from 1 January 1990 to 30 June 2017), in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. No restriction on study design was imposed. Patients with sporadic AML were included. The main interventions included active surveillance, surgery (nephron-sparing surgery and radical nephrectomy), selective arterial embolisation, and percutaneous or laparoscopic thermal ablations (radiofrequency, microwaves, or cryoablation). The outcomes included indications for active treatment, AML growth rate, AML recurrence rate, risk of bleeding, post-treatment renal function, adverse events of treatments, and modalities of followup. Risk of bias assessment was performed using standard Cochrane methods. Evidence synthesis: Among 2704 articles identified, 43 were eligible for inclusion (zero randomised controlled trials, nine nonrandomised comparative retrospective studies, and 34 single-arm case series). Most studies were retrospective and uncontrolled, and had a moderate to high risk of bias. Conclusions: In active surveillance series, spontaneous bleeding was reported in 2% of patients and active treatment was undertaken in 5%. Active surveillance is the most chosen option in 48% of the cases, followed by surgery in 31% and selective arterial embolisation in 17% of the cases. Selective arterial embolisation appeared to reduce AML volume but required secondary treatment in 30% of the cases. Surgery (particularly nephron-sparing surgery) was the most effective treatment in terms of recurrence and need for secondary procedures. Thermal ablation was an infrequent option. The association between AML size and the risk of bleeding remained unclear; as such the traditional 4-cm cut-off should not per se trigger active treatment. In spite of the limitations and uncertainties relating to the evidence base, the findings may be used to guide and inform clinical practice, until more robust data emerge. Patient summary: Sporadic angiomyolipoma (AML) is a benign tumour of the kidney consisting of a mixture of blood vessels, fat, and muscle. Large tumours may have a risk of spontaneous bleeding. However, the size beyond which these tumours need to be treated remains unclear. Most small AMLs can be monitored without any active treatment. For those who need treatment, options include surgical removal of the tumour or stopping its blood supply (selective embolisation). Surgery has a lower recurrence rate and lower need for a repeat surgical procedure.

Forskningsöversikt (refereegranskat)abstract
- Context: Management of locally recurrent renal cancer is complex.Objective: In this systematic review we analyse the available literature on the management of local renal cancer recurrence.Evidence acquisition: A systematic search (PubMed, Web of Science, CINAHL, Clinical Trials, and Scopus) of English literature from 2000 to 2017 was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.Evidence synthesis: The search identified 1838 articles. Of those, 36 were included in the evidence synthesis. The majority of the studies identified were retrospective and not controlled. Local recurrence after thermal ablation (TA) may be managed with repeat TA. Alternatively, salvage nephrectomy is possible. However, a higher rate of complications should be expected than after primary nephrectomy. Salvage nephrectomy and TA represent treatment options for local recurrence after partial nephrectomy. Local retroperitoneal recurrence after radical nephrectomy is ideally treated with surgical resection, for which minimally invasive approaches might be applicable to select patients. For large recurrences, addition of intraoperative radiation may improve local control. Local tumour destruction appears to be more beneficial than systemic therapy alone for local recurrences.Conclusions: Management of local renal cancer relapse varies according to the clinical course and prior treatments. The available data are mainly limited to noncontrolled retrospective series. After nephron-sparing treatment, TA represents an effective treatment with low morbidity. For local recurrence after radical nephrectomy, the low-level evidence available suggests superiority of surgical excision relative to systemic therapy or best supportive care. As a consequence, surgery should be prioritised when feasible and applicable.Patient summary: In renal cell cancer, the occurrence and management of local recurrence depend on the initial treatment. This cancer is a disease with a highly variable clinical course. After initial organ-sparing treatment, thermal ablation offers good cancer control and low rates of complications. For recurrence after radical nephrectomy, surgical excision seems to provide the best long-term cancer control and it is superior to medical therapy alone.

- Context: The European Association of Urology Guideline Panel for Renal Cell Carcinoma (RCC) has prepared evidence-based guidelines and recommendations for RCC management. Objectives: To provide an update of the 2010 RCC guideline based on a standardised methodology that is robust, transparent, reproducible, and reliable. Evidence acquisition: For the 2014 update, the panel prioritised the following topics: percutaneous biopsy of renal masses, treatment of localised RCC (including surgical and nonsurgical management), lymph node dissection, management of venous thrombus, systemic therapy, and local treatment of metastases, for which evidence synthesis was undertaken based on systematic reviews adhering to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Relevant databases (Medline, Cochrane Library, trial registries, conference proceedings) were searched (January 2000 to November 2013) including randomised controlled trials (RCTs) and retrospective or controlled studies with a comparator arm. Risk of bias (RoB) assessment and qualitative and quantitative synthesis of the evidence were performed. The remaining sections of the document were updated following a structured literature assessment. Evidence synthesis: All chapters of the RCC guideline were updated. For the various systematic reviews, the search identified a total of 10 862 articles. A total of 151 studies reporting on 78 792 patients were eligible for inclusion; where applicable, data from RCTs were included and meta-analyses were performed. For RCTs, there was low RoB across studies; however, clinical and methodological heterogeneity prevented data pooling for most studies. The majority of studies included were retrospective with matched or unmatched cohorts based on single or multi-institutional data or national registries. The exception was for systemic treatment of metastatic RCC, in which several RCTs have been performed, resulting in recommendations based on higher levels of evidence. Conclusions: The 2014 guideline has been updated by a multidisciplinary panel using the highest methodological standards, and provides the best and most reliable contemporary evidence base for RCC management. Patient summary: The European Association of Urology Guideline Panel for Renal Cell Carcinoma has thoroughly evaluated available research data on kidney cancer to establish international standards for the care of kidney cancer patients.

- Context: The European Association of Urology Renal Cell Carcinoma (RCC) Guideline Panel has prepared evidence-based guidelines and recommendations for the management of RCC. Objective: To provide an updated RCC guideline based on standardised methodology including systematic reviews, which is robust, transparent, reproducible, and reliable. Evidence acquisition: For the 2019 update, evidence synthesis was undertaken based on a comprehensive and structured literature assessment for new and relevant data. Where necessary, formal systematic reviews adhering to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were undertaken. Relevant databases (Medline, Cochrane Libraries, trial registries, conference proceedings) were searched until June 2018, including randomised controlled trials (RCTs) and retrospective or controlled studies with a comparator arm, systematic reviews, and meta-analyses. Where relevant, risk of bias (RoB) assessment, and qualitative and quantitative syntheses of the evidence were performed. The remaining sections of the document were updated following a structured literature assessment. Clinical practice recommendations were developed and issued based on the modified GRADE framework. Evidence synthesis: All chapters of the RCC guidelines were updated based on a structured literature assessment, for prioritised topics based on the availability of robust data. For RCTs, RoB was low across studies. For most non-RCTs, clinical and methodological heterogeneity prevented pooling of data. The majority of included studies were retrospective with matched or unmatched cohorts, based on single- or multi-institutional data or national registries. The exception was for the treatment of metastatic RCC, for which there were several large RCTs, resulting in recommendations based on higher levels of evidence. Conclusions: The 2019 RCC guidelines have been updated by the multidisciplinary panel using the highest methodological standards. These guidelines provide the most reliable contemporary evidence base for the management of RCC in 2019. Patient summary: The European Association of Urology Renal Cell Carcinoma Guideline Panel has thoroughly evaluated the available research data on kidney cancer to establish international standards for the care of kidney cancer patients.

- Objective: To evaluate the role of the surgical technique used for the treatment of benign renal tumors, with regard to renal function and overall survival (OS) in patients without cancer-related mortality.Patients and methods: The study included 506 patients, mean age of 63.3 years, with histologically proven benign renal lesions originating from 5 European centers. Retrospective data from each hospital were retrieved and merged into a common database for analyses. OS, American Society of Anesthesiology score, and renal functions were measured in relation to surgical technique. The Mann-Witney U-test, the paired t-test, and Cox's multivariate analysis were used.Results: Patients treated with radical nephrectomy had significantly reduced renal function postoperatively compared with nephron sparing surgery (NSS). OS was significantly reduced after radical nephrectomy compared with NSS (P = .012), a survival difference that remained significant [hazard ratio (HR) 0.042, 95% confidence interval (CI) 0.221-0.972, P = .042] in multivariate analysis, together with age at diagnosis (HR 1.065, 95% CI 1.026-1.106, P = .001) and American Society of Anesthesiology score (HR 2.361, 95% CI 1.261-4.419, P = .007). Also renal function assessed by estimated glomerular filtration rate significantly correlated to survival in univariate analysis, but did not remain independent after multivariate analysis. Oncocytoma was the most frequent benign lesion, followed by angiomyolipoma.Conclusion: The present study in patients with benign renal tumors shows that the remaining renal function and OS correspond to the choice of surgical procedure. Our results support the recommendation to perform NSS whenever possible when surgery is performed for patients with renal masses. The limitations of the study are the retrospective design and the selection bias for the surgical approach.

- IntroductionRecent trials have emphasized the importance of a precise patient selection for cytoreductive nephrectomy (CN). In 2013, a nomogram was developed for pre- and postoperative prediction of the probability of death (PoD) after CN in patients with metastatic renal cell carcinoma. To date, the single-institutional nomogram which included mostly patients from the cytokine era has not been externally validated. Our objective is to validate the predictive model in contemporary patients in the targeted therapy era.MethodsMulti-institutional European and North American data from patients who underwent CN between 2006 and 2013 were used for external validation. Variables evaluated included preoperative serum albumin and lactate dehydrogenase levels, intraoperative blood transfusions (yes/no) and postoperative pathologic stage (primary tumour and nodes). In addition, patient characteristics and MSKCC risk factors were collected. Using the original calibration indices and quantiles of the distribution of predictions, Kaplan-Meier estimates and calibration plots of observed versus predicted PoD were calculated. For the preoperative model a decision curve analysis (DCA) was performed.ResultsOf 1108 patients [median OS of 27months (95% CI 24.6-29.4)], 536 and 469 patients had full data for the validation of the pre- and postoperative models, respectively. The AUC for the pre- and postoperative model was 0.68 (95% CI 0.62-0.74) and 0.73 (95% CI 0.68-0.78), respectively. In the DCA the preoperative model performs well within threshold survival probabilities of 20-50%. Most important limitation was the retrospective collection of this external validation dataset.ConclusionsIn this external validation, the pre- and postoperative nomograms predicting PoD following CN were well calibrated. Although performance of the preoperative nomogram was lower than in the internal validation, it retains the ability to predict early death after CN.

- Context: The role of percutaneous renal tumour biopsy (RTB) remains controversial due to uncertainties regarding its diagnostic accuracy and safety.Objective: We performed a systematic review and meta-analysis to determine the safety and accuracy of percutaneous RTB for the diagnosis of malignancy, histologic tumour subtype, and grade.Evidence acquisition: Medline, Embase, and Cochrane Library were searched for studies providing data on diagnostic accuracy and complications of percutaneous core biopsy (CB) or fine-needle aspiration (FNA) of renal tumours. A meta-analysis was performed to obtain pooled estimates of sensitivity and specificity for diagnosis of malignancy. The Cohen kappa coefficient (κ) was estimated for the analysis of histotype/grade concordance between diagnosis on RTB and surgical specimen. Risk of bias assessment was performed (QUADAS-2).Evidence synthesis: A total of 57 studies recruiting 5228 patients were included. The overall median diagnostic rate of RTB was 92%. The sensitivity and specificity of diagnostic CBs and FNAs were 99.1% and 99.7%, and 93.2% and 89.8%, respectively. A good (κ = 0.683) and a fair (κ = 0.34) agreement were observed between histologic subtype and Fuhrman grade on RTB and surgical specimen, respectively. A very low rate of Clavien ≥2 complications was reported. Study limitations included selection and differential-verification bias.Conclusions: RTB is safe and has a high diagnostic yield in experienced centres. Both CB and FNA have good accuracy for the diagnosis of malignancy and histologic subtype, with better performance for CB. The accuracy for Fuhrman grade is fair. Overall, the quality of the evidence was moderate. Prospective cohort studies recruiting consecutive patients and using homogeneous reference standards are required.Patient summary: We systematically reviewed the literature to assess the safety and diagnostic performance of renal tumour biopsy (RTB). The results suggest that RTB has good accuracy in diagnosing renal cancer and its subtypes, and it appears to be safe. However, the quality of evidence was moderate, and better quality studies are required to provide a more definitive answer.

- Context: The benefit of surgical metastasectomy (SM) for patients with metastatic renal cell carcinoma (mRCC) remains controversial because of the lack of high-level evidence on the role of SM in terms of survival benefit in the era of systemic therapy.Objective: To perform a systematic review of the literature on the role of SM in the treatment of mRCC and discuss key issues in the SM decision-making process.Evidence acquisition: A systematic search of the Embase and Medline databases was carried out and a systematic review of the role of SM in mRCC was performed. A total of 56 studies were finally included in the evidence synthesis.Evidence synthesis: All the studies included were retrospective and mostly non-comparative. Median overall survival (OS) ranged from 36 to 142 mo for those undergoing SM, compared to 8-27 mo for no SM. SM was associated with a lower risk of all-cause mortality compared to no SM (pooled adjusted hazard ratio 2.37, 95% confidence interval 2.03-2.87; p < 0.001). Morbidity and mortality were similar for SM and primary tumor surgery. The most important prognostic factor for OS was complete resection of metastases. Other prognostic factors included disease free-survival from nephrectomy, primary tumor features (T stage >= 3, high grade, sarcomatoid features, and pathological nodal status), the number of metastases, and performance status. Lung metastasectomy seemed to show the best survival benefit.Conclusions: Although no randomized clinical data are available, published studies support the role of SM in selected patients in the modern era. Complete SM allows sustained survival free of systemic treatment. Integration of SM and systemic therapy in a multimodal approach remains a valid option for some patients.Patient summary: Surgical resection of metastases originating from renal cell carcinoma may play a role in prolonging survival and avoiding systemic therapy when complete resection is achievable. This strategy is an option for selected patients with a limited number of metastases who still have good general health status.
