Abstract
Small renal masses (SRMs) are a heterogeneous group of tumours with varying metastatic potential. The increasing use and improving quality of abdominal imaging have led to increasingly early diagnosis of incidental SRMs that are asymptomatic and organ confined. Despite improvements in imaging and the growing use of renal mass biopsy, diagnosis of malignancy before treatment remains challenging. Management of SRMs has shifted away from radical nephrectomy, with active surveillance and nephron-sparing surgery taking over as the primary modalities of treatment. The optimal treatment strategy for SRMs continues to evolve as factors affecting short-term and long-term outcomes in this patient cohort are elucidated through studies from prospective data registries. Evidence from rapidly evolving research in biomarkers, imaging modalities, and machine learning shows promise in improving understanding of the biology and management of this patient cohort.

Abstract
BACKGROUND Both partial nephrectomy (pNx) and total nephrectomy (TNx) are the mainstay of the surgical treatment of renal cell carcinoma. In smaller masses, ablative treatment as well as surveillance are possible options. OBJECTIVE The aim of this article is to provide a closer look at the surgical methods, active surveillance and ablative options as well as the current evidence to support their use. MATERIAL AND METHODS This study is based on a selective literature review regarding pNx and TNx for renal cell carcinoma using the PubMed database and the review of current European and American guidelines on surgical treatment and conservative options for renal cell carcinoma. RESULTS The choice of surgical method depends on the intrarenal tumor configuration as well as patient comorbidities. While pNx is used for smaller localized masses TNx is usually performed in larger more complex tumors. Both methods can be performed using a minimally invasive (laparoscopic or robotically assisted) or an open approach. In patients with severe comorbidities or a limited life expectancy, local ablative treatment options as well as surveillance strategies are suitable strategies.

Abstract
Renal cell carcinoma (RCC) is one of the most lethal genitourinary cancers, with the highest mortality rate, and may remain undetected throughout its development. RCC can be sporadic or hereditary. Exploring the underlying genetic abnormalities in RCC will have important implications for understanding the origins of nonhereditary renal cancers. The treatment of RCC has evolved over centuries from the era of cytokines to targeted therapy to immunotherapy. A surgical cure is the primary treatment modality, especially for organ-confined diseases. Furthermore, the urologic oncology community focuses on nephron-sparing surgical approaches and ablative procedures when small renal masses are detected incidentally in conjunction with interventional radiologists. In addition to new combination therapies approved for RCC treatment, several trials have been conducted to investigate the potential benefits of certain drugs. This may lead to durable responses and more extended survival benefits for patients with metastatic RCC (mRCC). Several approved drugs have reduced the mortality rate of patients with RCC by targeting VEGF signaling and mTOR. This review better explains the signaling pathways involved in the RCC progression, oncometabolites, and essential biomarkers in RCC that can be used for its diagnosis. Further, it provides an overview of the characteristics of RCC carcinogenesis to assist in combating treatment resistance, as well as details about the current management and future therapeutic options. In the future, multimodal and integrated care will be available, with new treatment options emerging as we learn more about the disease.

Abstract
Laparoscopic education and surgery assessments increase the success rates and lower the risks during actual surgeries. Hospital residents need a secure setting, and trainees require a safe and controlled environment with cost-effective resources where they may hone their laparoscopic abilities. Thus, we have modeled and developed a surgical simulator to provide the initial training in Laparoscopic Partial Nephrectomy (LPN-a procedure to treat kidney cancer or renal masses). To achieve this, we created a virtual simulator using an open-source game engine that can be used with a commercially available, reasonably priced virtual reality (VR) device providing visual and haptic feedback. In this study, the proposed simulator's design is presented, costs are contrasted, and the simulator's performance is assessed using face and content validity measures. CPU- and GPU-based computers can run the novel simulation with a soft body deformation based on simplex meshes. With a reasonable trade-off between price and performance, the HTC Vive's controlled soft body effect, physics-based deformation, and haptic rendering offer the advantages of an excellent surgical simulator. The trials show that the medical volunteers who performed the initial LPN procedures for newbie surgeons received positive feedback.

Abstract
PURPOSE To explore the current role of lymph node dissection (LND) in the management of nonmetastatic localized renal cell carcinoma (RCC). BACKGROUND There is currently no proven benefit of LND in the setting of RCC, and its role remains controversial because of conflicting evidence. Patients who may benefit from LND are those at greatest risk of nodal disease, but the tools used to predict nodal involvement are limited due to unpredictable retroperitoneal lymphatics. The indications, templates, and extent of LND are also not standardized, adding to the ambiguity of current guidelines surrounding its use. EVIDENCE ACQUISITION A PubMed search of the literature from January 2017 to December 2022 was conducted using the search terms "renal cell carcinoma" or "renal cancer" in combination with "lymph node dissection" or "lymphadenectomy". Case studies and editorials were excluded, whereas studies investigating the therapeutic effect of LND were classified as either demonstrating a benefit or no benefit. References of the studies and review articles were also searched for notable studies and findings that were outside the five-year literature search. The studies in this review were restricted to the English language. RESULTS Only a number of studies in recent years have found an association between the extent of LND and increased survival. Most studies do not indicate an associated benefit, and some even suggest a negative effect on survival. Most of these studies are retrospective. CONCLUSION The therapeutic value of LND in RCC is still unclear, and although prospective data are needed, its declining rates and emerging new therapies make this unlikely. A better understanding of renal lymphatics and improved detection of nodal disease may help determine the role of LND in nonmetastatic localized RCC.

Abstract
Renal cell carcinoma (RCC) accounts for 2-3% of all malignant disease in adults, with 30% of RCC diagnosed at locally advanced or metastatic stages of disease. A form of locally advanced disease is the tumor thrombus (TT), which commonly grows from the intrarenal veins, through the main renal vein, and up the inferior vena cava (IVC), and rarely, into the right cardiac chambers. Advances in all areas of medicine have allowed increased understanding of the underlying biology of these tumors and improved preoperative staging. Although the development of several novel system agents, including several clinical trials utilizing immune checkpoint inhibitors and combination therapies, has been shown to lower perioperative morbidity and increase post-operative recurrence-free and progression-free survival, surgery remains the mainstay of therapy to achieve a cure. In this review, we provide a description of specific surgical approaches and techniques used to minimize intra- and post-operative complications during radical nephrectomy and tumor thrombectomy of RCC with TT extension of various levels. Additionally, we provide an in-depth review of the major developments in neoadjuvant and adjuvant immunotherapy-based treatment and the impact of ongoing and recently completed clinical trials on the surgical treatment of advanced RCC.

Abstract
A nephrometry scoring system is a key standard to evaluate the feasibility of partial nephrectomy (PN). Whether based on two-dimensional or three-dimensional images, simplicity, effectiveness, and practicality are the keys to the nephrometric scoring system. Since the emergence of RENAL score in 2009, numerous scoring systems based on different anatomical parameters are established to seek accurately and few parameters to assess the risk of PN and complications. This study aimed to achieve a three-game winning streak in PN more easily and efficiently (negative resection margin, maximum preservation of normal nephron function, and avoiding short-term and long-term complications). Using PubMed, we counted 28 kinds of nephrometric scoring systems. We considered only English literatures published and excluded editorials, commentaries, and meeting abstracts. To the best of our knowledge, this is to date and most comprehensive summary as well as an outlook of the nephrometric scoring system.

Abstract
Background When we treat renal cell carcinoma by laparoscopic nephron-sparing surgery (NSS), it is essential to use an evaluation system to predict clinical outcomes. Hitherto, there are more than a dozen nephrometry score systems. In this study, through assessing the correlations between nephrometry score systems and clinical outcomes, we aim to provide a novel nephrometry score system—the “3S+f” score system—to simplify the evaluation of technical complexity of partial nephrectomy. Methods We retrospectively collected the data of 131 patients who underwent NSS, which was performed by a single surgeon (SZ) from January 2013 to July 2018 at Peking University Third Hospital. The “3S+f” score system contains four parameters: “size, side, site, and fat”, all of which can be obtained from preoperative imaging data. We evaluated the correlations between the “3S+f” score and clinical outcomes, and compared R.E.N.A.L. score and PADUA score. Results All the three nephrometry score systems were related to some clinical outcomes in univariate analyses. In multivariate regression models, the “3S+f” score, the R.E.N.A.L. score, and the PADUA score were significantly associated with operative time (p = 0.016, p = 0.035, and p = 0.001, respectively) and warm ischemia time (all p = 0.008, p < 0.001, and p < 0.001, respectively). “3S+f” was also significantly related to extubation time > 5 days (p = 0.018). In predicting operative time > 120 min and extubation time >5 days from ROC curves, the AUCs of the “3S+f” score (0.717 and 0.652, respectively) were larger than both the R.E.N.A.L (0.598 and 0.554, respectively) and PADUA (0.600 and 0.542, respectively) score systems. Conclusion A novel nephrometry score system—the “3S+f” score system—shows equivalent correlation and the ability in predicting clinical outcomes when compared to the R.E.N.A.L. score system and the PADUA score system, which can describe renal tumors.

Abstract
MN/CA9 is a cell surface glycoprotein and a tumor-associated antigen. It plays a crucial role in the regulation of cell proliferation and oncogenesis. There is no ideal tumor marker currently available for renal cell carcinoma (RCC) with sufficient sensitivity and specificity. Therefore, we studied MN/CA9 gene expression in the tumor tissue, apparently normal kidney tissue, preoperative blood, and urine samples of patients with RCC. We included thirty cases of renal tumors (26 RCC and 4 benign tumors) in the study. We applied an RT-PCR assay for MN/CA9 gene expression to 26 RCC kidney tumor samples and four benign kidney tumor tissue samples. We also evaluated MN/CA9 gene expression in preoperative blood and urine samples of 15 of these cases. Additionally, thirty-five grossly normal renal tissue samples, including 21 from kidneys with RCC, were also evaluated for gene expression. The RT-PCR analysis revealed that twenty-one out of 26 RCC tissue samples showed MN/CA9 gene expression compared to three out of 35 non-malignant renal tissue samples (p < 0.05). Two out of four benign renal tissue samples also expressed this gene. We also observed MN/CA9 gene expression in nine out of 15 blood samples and four out of 15 urine samples. All patients with urinary MN/CA9 gene expression showed expression in blood and tumor tissue samples. We found a correlation in terms of MN/CA9 expression between blood and tumor tissue samples of RCC patients as those who exhibit MN/CA9 expression in blood were also positive at the tumor tissue levels. The difference in MN/CA9 gene expression in tumor tissue, blood, and urine samples in relation to the stage of the disease, nuclear grade, and histological cell-type was not statistically significant. However, all the three patients who had metastatic RCC had MN/CA9 gene expression in their blood. The existence of a tumor-associated antigen such as MN/CA9 may present a possible target for molecular diagnosis and management of RCC.

Abstract
PURPOSE We evaluated our experience of a multidisciplinary approach to renal mass biopsy (RMB) for small renal masses (SRM) employing in-office ultrasound (US) guided biopsy by urology (24%), computed tomography (CT) or US biopsy by interventional radiology (IR) (79%), and endoscopic ultrasound-guided biopsy by gastroenterology (GI) (4%). METHODS A single-institution retrospective review of patients who underwent RMB for SRM from May 2013 to August 2019 was conducted. Data regarding patient demographics, tumor characteristics, biopsy technique, histopathology, and management were collected. Diagnostic rates, concordance with final pathology, complications, and outcomes were analyzed. RESULTS Of the 192 biopsies reviewed, 63% biopsies were malignant, 20% were benign, and 17% were non-diagnostic. Based on biopsy results, 71 patients (37%) elected active surveillance. Thirty-eight (20%) patients underwent cryoablation, 56 (29%) underwent partial nephrectomy (PN), 14 (7%) underwent radical nephrectomy (RN) and the remaining patients were treated elsewhere. The rate of surgery for benign pathology after pretreatment RMB was 3%. The concordance rate between biopsy and final pathology was 99% for malignancy, 96% for specific pathology subtype, and 85% for RCC grade. Median time from diagnosis to definitive treatment was 97 days (urology: 76, IR: 110 and GI: 54, p=0.002). Three (1.6%) Clavien I complications were reported. CONCLUSION Our multidisciplinary approach to renal mass biopsy for clinical stage T1a demonstrated favorable safety and diagnostic rates, which effectively directed management strategies and minimized surgery for benign disease. Urologist performed office-biopsies significantly shortened the time from diagnosis to definitive treatment. Our experience with GI EUS biopsy has demonstrated feasibility and safety for tumors that were otherwise not accessible percutaneously.

Abstract
INTRODUCTION AND OBJECTIVES Preoperative renal artery embolization (PRAE) for large renal masses may be performed prior to nephrectomy in order to simplify the procedure and reduce intraoperative bleeding. The objective of this work is to determine the role of PRAE on intraoperative bleeding and postoperative complications in left renal tumors with tumor thrombus limited to the left renal vein (level 0). MATERIAL AND METHODS Retrospective analysis to evaluate 46 patients who underwent left radical nephrectomy and thrombectomy for the treatment of renal cell carcinoma with level 0 tumor thrombus during the period 1990-2020. PRAE was limited to those cases in which surgical access to the main renal artery was presumed a priori difficult in the preoperative imaging study (n = 9; 19.6%). Intraoperative bleeding was estimated based on the perioperative transfusion rate, and postoperative complications were categorized according to the Clavien-Dindo classification. The Chi-squared test was used for comparisons. A multivariate analysis was performed to identify predictors of transfusion and complications. RESULTS There were no significant differences in the overall complication rate (11.1% vs. 32.4%, p = 0.19), major complication rate (0% vs. 8.1%, p = 0.51), or transfusion rate (11.1% vs. 19%, p = 0.49) between both groups (PRAE vs. non-PRAE). In the multivariate analysis, PRAE did not behave as a predictor of complications (OR: 0.11, 95%CI 0.01-2.86; p = 0.18) nor transfusion (OR: 0.46, 95%CI 0.02-7.38; p = 0.58). CONCLUSIONS In our study on left RCC with level 0 tumor thrombus and difficult access to the main renal artery, PRAE was not associated with increased bleeding or postoperative complications, and it did not behave as an independent predictor of these variables. Therefore, it could be used as a preoperative maneuver to facilitate vascular management in selected cases.

Adrenalectomy During Radical Nephrectomy- Incidence and Oncologic Outcomes From the Canadian Kidney Cancer Information System (CKCis) -A Modern Era, Nationwide, Multicenter Cohort. Urology 2021; 157:168-173. [PMID: 34129893 DOI: 10.1016/j.urology.2021.05.053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 04/20/2021] [Accepted: 05/28/2021] [Indexed: 01/20/2023]
Abstract
OBJECTIVE To characterize proportion of patients receiving adrenalectomy, adrenal involvement prevalence and oncologic outcomes of routine adrenalectomy in contemporary practice. Ipsilateral adrenalectomy was once standard during radical nephrectomy. However, benefit of routine adrenalectomy has been questioned because adrenal involvement of renal cell carcinoma (RCC) is low. METHODS All patients receiving radical nephrectomy in the Canadian Kidney Cancer information system, a collaborative prospective cohort populated by 14 major Canadian centers, between January 2011 to February 2020 were included. Patients were excluded if they had non-RCC histology, multiple tumors, contralateral tumors, metastatic disease or previous history of RCC. Patient demographic, clinical, and surgical information were summarized and compared. Cox-proportional hazards was used for multivariable analysis. RESULTS During study period, 2759 patients received radical nephrectomy, of these, 831(30.1%) had concomitant adrenalectomy. Pathological adrenal involvement was identified in 102 (3.7%overall; 12.3%of adrenalectomy). Median follow-up was 21.6months (Interquartile range 7.0-46.5). Patients with adrenalectomy had higher venous tumor thrombus (30.3% vs 9.6%; P <.0001), higher T stage (71.1% vs 43.4% pT3/4; P <.0001), lymph node metastases (17.6% vs 10.7%; P = .0035), Fuhrman grades (71.4% of Fuhrman grades 3/4 vs 56.2%; P <.0001) and increased proportion of clear cell histology (79.3% vs 74.5%; P = .0074) compared to the no adrenalectomy group. Adrenalectomy patients had higher risk of recurrence (HR 1.23; 95% CI 1.04-1.47; P = .019) and no difference in survival (HR 1.09, 95% CI 0.86-1.38, P = .48). CONCLUSION Adrenalectomy is not associated with better oncological outcome of recurrence/survival. Adrenalectomy should be reserved for patients with radiographic adrenal involvement and/or intra-operative adrenal involvement.

Abstract
The good oncologic results after partial nephrectomy for stage 1 RCC show that radical nephrectomy is an overtreatment in most cases, and that many healthy nephrons are removed unnecessarily. However, partial nephrectomy is a difficult operation, with increased blood loss and a higher risk of complications. Therefore, the advantage of preserved function has to be weighed up against the increased trauma of surgery in each individual patient, and the assessment of preoperative function may influence this decision, among other factors such as comorbidities and age. In most studies, renal function has been assessed by means of estimated glomerular filtration rate, and this parameter is very helpful for long-term studies in large populations. However, more precise measurement based on clearance studies are sometimes required for more sophisticated investigations. The technique of partial nephrectomy has evolved substantially in recent years, resulting in the preservation of more nephrons, less damage to the remaining parenchyma, less blood loss, and a decreased risk of complications. The introduction of minimally invasive surgery for this purpose has also decreased the overall morbidity of surgery. In the long-term, chronic kidney disease may result in increased cardiac mortality. There is ongoing discussion on this problem, however, this potential negative influence on overall survival is not only influenced by the rate of renal insufficiency, but also to a great extent by other comorbidities such as hypertension and diabetes. Therefore, in addition to providing the best surgery for any given patient, we have to make sure that the treatment of the comorbidities will also be part of our patient management, since the risk of cardiac failure may be greater than the risk of poor oncologic outcome.

Abstract
Minimally invasive renal surgery has revolutionized the surgical management of renal cancer since the initial report of laparoscopic nephrectomy in 1991. Laparoscopic nephrectomy became the mainstay of management in surgically resectable renal masses since the 1990s. The growing body of literature supporting nephron-sparing surgery over the last two decades has meant that minimally invasive radical nephrectomy (MI-RN) is now the preferred treatment for renal tumors not amenable to partial nephrectomy. While there is a well-described experience with complex radical nephrectomy using standard laparoscopy, robot-assisted surgery has shortened the learning curve and facilitated greater uptake of minimally invasive surgery in difficult surgical scenarios traditionally performed open surgically. Increased experience and expertise with robot-assisted renal surgery has led to expansion of the indications for MI-RN to include larger masses, locally advanced renal masses invading adjacent tissues or regional hilar/retroperitoneal lymph nodes, cytoreductive nephrectomy (CN) in metastatic disease, and concurrent venous tumor thrombectomy for renal vein or inferior vena cava (IVC) involvement. In this article, we review the various surgical techniques and adjunctive procedures associated with MI-RN.

Abstract
Pediatric renal cell carcinoma (RCC) is a rare type of kidney cancer, most commonly occurring in teenagers and young adolescents. Few relatively large series of pediatric RCC have been reported. Knowledge of clinical characteristics, outcome and treatment strategies are often based on the more frequently occurring adult types of RCC. However, published pediatric data suggest that clinical, molecular and histological characteristics of pediatric RCC differ from adult RCC. This paper summarizes reported series consisting of ≥10 RCC pediatric patients in order to create an up-to-date overview of the clinical and histopathological characteristics, treatment and outcome of pediatric RCC patients.

Abstract
Lymph node involvement in renal cell carcinoma (RCC) correlates with poor oncologic outcomes. However, current RCC staging guidelines may not fully reflect the survival impact of lymph node positive disease. Recent data demonstrates that nodal disease has significant impact on survival and modifications to current staging guidelines have been proposed. Lymph node dissection (LND) at the time of surgical intervention for RCC remains controversial. While clinical trial data have demonstrated conflicting evidence for LND, some institutional studies suggests that carefully selected patients at high-risk for recurrence may benefit from LND. Prospectively, clinical trials are examining treating nodal disease and disease at high-risk of recurrence in the neoadjuvant and/or adjuvant setting at the time of nephrectomy. These promising trials are poised, if successful, to influence the treatment paradigm for localized RCC.

Abstract
Objectives Radical nephrectomy (RN) was the standard treatment for renal cell carcinoma (RCC). However, recent studies have found that partial nephrectomy (PN) could achieve similar effects as radical nephrectomy, and has the advantages of less bleeding and shorter hospital stay. The choice of surgical strategies has become a concern of clinicians, which could be guided by renal score introduced by Kutikov et al Therefore, we conducted this meta‐analysis to clarify the value of renal score of determining surgical strategies and predicting complications. Methods The keywords “RENAL score,” “renal nephrometry score,” or “nephrometry score” were used to retrieve electronic databases for relevant literature up to Feb 2020, including PubMed, Web of Science, and the Cochrane library. Surgical strategies and complications are outcome measures. Risk ratio (RR) with 95% confidence intervals (CI) is applied to assess the effect size. Results A total of 20 studies met the selection criteria for meta‐analysis. There was significant difference in RN operation rate for each subgroup (low‐moderate: RR = 3.50, 95% Cl = 2.60‐4.71, P < .001; low‐high: RR = 6.29, 95% Cl = 4.40‐9.00, P < .001; moderate‐high: RR = 1.80, 95% Cl = 1.39‐2.32, P < .001).The overall incidence of complications from high renal score group was significantly higher than that in low renal score group (low‐moderate: RR = 1.32, 95% Cl = 1.03‐1.69, P = .026; low‐high: RR = 2.45, 95% Cl = 1.48‐4.07, P = .001; moderate‐high: RR = 1.75, 95% Cl = 1.17‐2.61, P = .007). Conclusions This meta‐analysis indicated that renal score is an efficient tool for determining surgical strategies and predicting complications in PN. More prospective research is essential to verify the predictive value of renal score.

Abstract
Introduction Renal artery embolization is performed before radical nephrectomy (RN) for renal mass in order to induce preoperative infarction and to facilitate surgical intervention through decrease of intraoperative bleeding. Moreover, in metastatic renal cancer it seems to stimulate tumour-specific antibodies, even if no established benefits in clinical response or survival have been reported. The role of preoperative renal artery embolization (PRAE) in management of renal masses has been often debated and its real benefits are still unclear. Nevertheless, in huge and complex renal masses, which are often characterized by a high and anarchic blood supply and rapid local invasion, radical nephrectomy can be challenging even for skilled surgeons. The aim of this prospective randomized study was to evaluate the effectiveness and safety of PRAE in complex masses by comparing perioperative outcomes of RN with and without PRAE. Materials and methods From December 2015 to May 2018 we enrolled prospectively 64 patients who underwent RN for localized (T2a-b) or locally advanced (T3 and T4) or advanced (N+, M+) renal cancers. Patients were divided in two groups. The first group included 30 patients who underwent PRAE; in the second group we enrolled 34 patients who did not undergo RN without PRAE. Perioperative outcomes in terms of operative time, blood loss, transfusion rate and length of hospitalization were evaluated. Statistical analysis was performed using GraphPad Prism 6.0 software. Results Median blood loss was 250 ml (50-500) and 400 ml (50-1000) in the first and second group, respectively, with a statistically significant difference (p=0.0066). Median surgical time was 200 min (90-390) and 240 min (130-390) in PRAE and No-PRAE group (p=0.06), respectively. No major complications occurred after embolization. Overall complication rate in Group 1 and 2 was 46.7% (14/30) and 50% (17/34), respectively (p=0.34). No major complications occurred in both groups. The mean follow up was 21,5 months. Conclusions Our results prove PRAE to be a safe procedure with low complications rate. To our experience, PRAE seems to be a useful tool in surgical management of a large mass and advanced disease.

[PMID: 32995279 PMCID: PMC7499324 DOI: 10.1016/j.ajur.2019.09.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2019] [Revised: 03/02/2019] [Accepted: 04/23/2019] [Indexed: 11/17/2022] Open
Abstract
Objective Once chronic inflammatory renal disease (IRD) develops, it creates a severe peri-fibrotic process, which makes it a relative contraindication for minimally invasive surgery (MIS). Our objective is to show that laparoscopic nephrectomy (LN) is a surgical option in IRD with fewer complications and better outcomes. Methods Retrospective review of patients who underwent a modified-surgical laparoscopic transperitoneal nephrectomy was performed. Data search included all operated patients between May 2013 and May 2018 that had a pathology result with any renal inflammatory condition (xanthogranulomatous pyelonephritis, chronic nephritis, and renal tuberculosis). We describe intra-operative variables such as operative time, blood loss, conversion rate, postoperative complications and length of hospital stay. Results There were 51 patients who underwent laparoscopic nephrectomy with a confirmatory pathology report for IRD. We identified four (8%) major complications; three of them required transfusion and one conversion to open surgery. The mean operative time was 233±108 min. Mean estimated blood loss was 206±242 mL excluding the conversion cases and 281±423 mL including them. The mean length of hospital stay was 3.0±2.0 days. Conclusion Laparoscopic nephrectomy for IRD can safely be done. It is a reproducible technique with low risks and complication rates. Our experience supports that releasing the kidney first and leaving the hilum for the end is a safe approach when vascular structures are embedded into a single block of inflammatory and scar tissue.

Radical Nephrectomy with or without Lymph Node Dissection for pT3 Renal Cell Carcinoma: A Propensity Score-based Analysis. J Cancer 2019; 10:2369-2375. [PMID: 31258740 PMCID: PMC6584409 DOI: 10.7150/jca.30375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2018] [Accepted: 04/25/2019] [Indexed: 11/30/2022] Open
Abstract
Objectives: To study whether radical nephrectomy (RN) with lymph node dissection (LND) can benefit pT3 renal cell carcinoma (RCC) patients versus no LND under the 2018 American Joint Committee on Cancer TNM classification system. Subjects/Patients and Methods: We performed a retrospective cohort study of clinicopathological data for 245 T3 RCC patients, who underwent radical nephrectomy between January 2006 and December 2013 at our center, including 67 (27.1%) who underwent LND. The relationships between the LND and progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS) were evaluated using 1:1 propensity score (PS) matching. Then, Kaplan-Meier survival analysis and Cox regression analysis were conducted to study whether these patients can benefit from LND. Depending on the LND number, we divided the cohort into two groups for further comparation. At last, we validated the results with the TCGA database KIRC patients. Results: The median follow-up time was 4.9 years. Sixty-seven pairs of patients were screened by the PS and were further analyzed. We conducted a Cox regression with the survival data and found that the LND group, compared with the non-LND group, showed no survival benefit on PFS, CSS, and OS (p = 0.444, 0.809, and 0.816, respectively). However, the removal of 5 or more LNs showed negative effect on OS (p = 0.0387). TCGA cohort results are mostly consistent with our findings. Conclusion: RN with LND cannot improve the PFS, CSS, or OS for pT3 renal cell carcinoma patients.

Abstract
INTRODUCTION Rapid adoption of robotics has introduced a paradigm change in prostate cancer treatment, with more than 80% of prostatectomies performed robotically in 2015. For treatment of renal cell carcinoma (RCC), this change has not previously been reported. We evaluated trends in surgical management of RCC in Kaiser Permanente Southern California (KPSC) within the last 16 years, especially after adoption of robotics. METHODS From January 1999 to September 2015, all KPSC members who underwent surgical treatment of suspected RCC were included retrospectively. Surgical approach, patient age, sex, clinicopathology, Charlson Comorbidity Index, and chronic kidney disease status were analyzed using robust Poisson multivariate regression. RESULTS The study included 5237 patients. Partial nephrectomy was increasingly used during the study period, and its use surpassed radical nephrectomy in 2012. In a multivariate model, partial nephrectomy was associated with lower pathologic tumor stage (p < 0.001) and lower Charlson Comorbidity Index (p = 0.004) vs radical nephrectomy. Robot-assisted laparoscopic partial nephrectomy (RALPN) started in KPSC in March 2011, and its relative use among all RCC surgeries increased in the following 3 years by 125%, 45%, and 14%. Laparoscopic partial nephrectomy and laparoscopic radical nephrectomy were the most frequently used surgical approaches for localized RCC when RALPN started in 2011. However, RALPN surpassed laparoscopic partial nephrectomy and laparoscopic radical nephrectomy in 2012 and 2014, respectively. CONCLUSION During our study, partial nephrectomy became the most common surgery for treatment of localized RCC. Since 2014, RALPN has become the most common renal oncologic surgical modality in KPSC.

Abstract
Renal cell carcinoma is relatively common malignancy. Its imaging features are often non-specific and can present a diagnostic dilemma for clinicians. Historically, all patients with a renal mass underwent radical nephrectomy. Advances in technology have allowed for an increase in partial nephrectomies and percutaneous ablations. This essay briefly describes some of the imaging findings of renal cell carcinoma and several of its mimics followed by an in-depth review of procedural management with a particular focus on recent advancements.

Abstract
Introduction Nephron-sparing surgery in the form of partial nephrectomy (PN) is currently considered the standard treatment for relatively small localized renal cell tumors. Objectives This study aimed to determine outcomes of PN regarding complications, recurrence, and survival rates at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan. Methods We assessed the data of patients older than 18 years undergoing PN from January 2010 to June 2017 who met our inclusion criteria. Data were analyzed using IBM SPSS Statistics for Windows, Version 20.0 (IBM Corp., Armonk, NY). Results A total of 35 patients were studied, with a male to female ratio of 2.5:1 with median age of 50 years. The median hospital stay was four days (range: 3-7), and the median RENAL (radius, exophytic/endophytic properties, nearness of tumor to the collecting system or sinus in millimeters, anterior/posterior location relative to polar lines) Score was five (range: 4-10). The most common pathological tumor stage was T1 (94%), and the median size was 3.5 cm. On histopathology, clear-cell carcinoma was the most common tumor (incidence, 71%). The median Fuhrman’s grade was two. On final histopathology, four patients had positive margins. Among them, two patients showed a progressive deterioration in renal functions and were found to have residual disease six months later. Only one patient developed metastasis in the lung. Wound infection was observed in one patient while another had wound dehiscence. Urine leakage was noted in two patients. The median follow-up duration was 18 months (range: 3-84). Mean cancer-free survival was 78.6 months, and overall survival was 79.2 months. The projected three-year and five-year disease-free and overall survival was 96% and 94%, respectively. Conclusion PN is a viable option with excellent outcomes regarding the complication profile, recurrence-free, and overall survival in patients with relatively small localized renal tumors.

Abstract
PURPOSE Lymph node (LN) involvement in renal cell carcinoma (RCC) is associated with a poor prognosis. While lymph node dissection (LND) may provide diagnostic information, its therapeutic benefit remains controversial. Thus, the aim of our study is to analyze survival outcomes after LND for nonmetastatic RCC and to characterize contemporary practice patterns. MATERIALS AND METHODS The National Cancer Database was queried for patients with nonmetastatic RCC who underwent either partial or radical nephrectomy from 2010 to 2014. A total of 11,867 underwent surgery and LND. Chi-square tests were used to examine differences in patient demographics. To minimize selection bias, propensity score matching (PSM) was used to select one control for each LND case (n = 19,500). Cox regression analyses were conducted to examine overall survival (OS) in patients who received LND compared to those who did not. RESULTS Of all patients undergoing LND for RCC (n = 11,867), 5%, 23%, 31%, 47% were performed for tumors of clinical T stage 1, 2, 3, and 4, respectively. Proportions of LND have not significantly changed from 2010 to 2014. No significant improvement in median OS for patients undergoing LND compared to no LND was shown (34.7 vs. 34.9 months, respectively; P = 0.98). Similarly, no significant improvement in median OS was found for clinically LN positive patients undergoing LND compared to no LND (P = 0.90). On Cox regression analysis, LND dissection was not associated with an OS benefit (hazard ratio: 1.00; 95% confidence interval 0.97 to 1.04). CONCLUSIONS Among all RCC patients, LNDs are often performed for low stage disease, suggesting a potential overutilization of LND. No OS benefit was seen in any subgroup of patients undergoing LND. Further investigation is needed to determine which patient populations may benefit most from LND.

Abstract
Capsular invasion is frequently detected in localized renal cell carcinoma (RCC) specimens and is associated with a poor prognosis, but the pretreatment imaging features are poorly known. This study aimed to explore the positions and margin types of RCC and various computed tomography (CT) signs, as well as the correlations with the presence/absence of RCC invasion of the renal capsule.This was a retrospective study of 158 consecutive patients treated for pathologically confirmed RCC between January 2013 and December 2016 at the Nantong University Affiliated Hospital. The patients were divided into the capsule invasion and noninvasion groups. The CT signs were analyzed (position type, margin type, and CT findings in the perirenal fat).There were 92 (58.2%) men and 66 (41.8%) women; mean age was 59.1 ± 12.8. Renal capsule invasion was confirmed in 45 cases. There was no difference in the position types between the 2 groups (all P > .05). The smooth margin was more common in the noninvasion group (53.1% vs 15.6%, P < .01). The deep lobulated type and the saw tooth sign were more common in the invasion group (57.8% vs 7.1%; and 40.0% vs 6.2%; both P < .01). The deep lobulated (OR = 2.03, 95%CI: 1.21-3.39, P = .007) and saw tooth (OR = 1.036, 95%CI: 1.008-1.065, P = .011) signs were independently associated with renal capsule invasion.Smooth tumor margin suggests the absence of renal capsule invasion, while the deep lobulated and the saw tooth signs strongly suggest the presence of renal capsule invasion in patients with RCC.

Abstract
From January 1985 to December 1987, 26 patients (20 men, 6 women, median age 62 years, range 26–76 years) with advanced renal cell carcinoma were included in the study. In 8 cases (6 patients no surgery, 2 patients with retroperitoneal node-residual disease after nephrectomy) metastases were identified at initial diagnosis, and in the remaining 18 the occurrence of metastases was delayed by a mean disease-free interval of 12 months after radical nephrectomy. Recombinant interferon alpha-2 was administered subcutaneously at a dose of 9 milion IU three times a week for a period of at least six months. Informed consent was obtained from all patients before starting therapy. No patients achieved complete regression of tumors; two cases showed a partial response (one relapsed six months later, while in the other response continues at 38 months after discontinuation of therapy); 10 patients showed stabilization of disease for 6–10 months and in 14 the disease progressed immediately. In our experience immunotherapy with recombinant interferon alpha-2 did not significantly change the natural history of renal cell carcinoma.

Abstract
The appropriate role of lymph node dissection (LND) in the management of patients with renal cell carcinoma (RCC) is still a matter of debate. There is ample evidence that LND is the most accurate modality for staging the regional lymph nodes (LNs), which may harbor metastatic disease in greater than one-third of patients with high-risk RCC. The presence of LN metastases is an independent negative prognostic factor in this disease and accurate determination of LN status not only helps with patient counselling regarding prognosis and tailoring of postoperative surveillance schedules, but it also identifies patients at high risk of systemic disease recurrence who may qualify for clinical trials of adjuvant systemic therapies. Meanwhile, the therapeutic value of LND has been brought into question by a randomized trial (European Organisation for Research and Treatment of Cancer; EORTC 30881) that showed no difference in progression-free or overall survival between patients who were treated with radical nephrectomy (RN) and LND and those treated with RN alone. Given that most patients enrolled in this trial had small renal masses and therefore were at low risk for LN metastases, the question of whether patients with high-risk tumors derive a therapeutic benefit from a standardized, extended LND remains unanswered.

Abstract
Nephrectomy, which constitutes a gold-standard procedure for the treatment of renal-cell carcinoma (RCC), has been widely discussed in the past decade as a significant risk factor of the development of chronic kidney disease (CKD). RCC is the third most common genitourinary cancer in the United States, with an estimated more than 65,000 new cases and 14,970 deaths. The aim of this review was to precisely and comprehensively summarize the status of current knowledge in CKD risk factors after nephrectomy, the advantages of minimally invasive vs. radical nephrectomy, post-nephrectomy biomarkers of CKD, ways of post-operative CKD prevention and, therefore, better understand why various aspects of CKD after nephrectomy. The majority of current studies indicated a better long-term kidney function preservation in patients undergoing partial nephrectomy in comparison to those after radical nephrectomy. Furthermore, a nephron-sparing surgery should be a preferred first-line procedure among young patients with small renal masses. As partial nephrectomy is followed by a greater risk of adverse outcomes relative to radical nephrectomy, a potential survival benefit should always be considered especially in the elderly or patients with comorbidities.

Abstract
Background Does the dogma of nephron sparing surgery (NSS) still stand for large renal masses? Available studies dealing with that issue are considerably biased often mixing imperative with elective indications for NSS and also including less malignant variants or even benign renal tumors. Here, we analyzed the oncological long-term outcomes of patients undergoing elective NSS or radical tumor nephrectomy (RN) for non-endophytic, large (≥7cm) clear cell renal carcinoma (ccRCC). Methods Prospectively acquired, clinical databases from two academic high-volume centers were screened for patients from 1980 to 2010. The query was strictly limited to patients with elective indications. Surgical complications were retrospectively assessed and classified using the Clavien-Dindo-classification system (CDS). Overall survival (OS) and cancer specific survival (CSS) were analyzed using the Kaplan-Meier-method and the log-rank test. Results Out of in total 8664 patients in the databases, 123 patients were identified (elective NSS (n = 18) or elective RN (n = 105)) for ≥7cm ccRCC. The median follow-up over all was 102 months (range 3–367 months). Compared to the RN group, the NSS group had a significantly longer median OS (p = 0.014) and median CSS (p = 0.04). Conclusions In large renal masses, NSS can be performed safely with acceptable complication rates. In terms of long-term OS and CSS, NSS was at least not inferior to RN. Our findings suggest that NSS should also be performed in patients presenting with renal tumors ≥7cm whenever technically feasible. Limitations include its retrospective nature and the limited availability of data concerning long-term development of renal function in the two groups.

Abstract
Cellular proliferative activity was evaluated by the determination of 3H-thymidine labeling index (LI) in 20 specimens of human urologic malignancies (13 renal cell carcinomas and 7 transitional cell bladder carcinomas). Very low LI values were found in renal cell carcinomas, with a median value of 0.28%. Slightly higher proliferative activities were observed in bladder carcinomas, with a median LI value of 1.96%. No significant correlations were found between proliferative activity and pathologic stage or histologic grading in renal cell carcinomas. Although the number of bladder carcinomas evaluated does not allow any definite conclusion, an increase in LI values was found from in situ to invasive carcinoma and from tumors at stage I to tumors at stage III.

Abstract
Although lymphadenectomy is currently accepted as most accurate and reliable staging procedure for lymph node metastases, its therapeutic benefit in renal cell carcinoma (RCC) still remains controversial. Although the new, targeted therapy paradigms have changed the treatment of patients with advanced RCC and offer prolonged survival, cure is extremely uncommon in the absence of surgical resections. In this paper, the current role of metastasectomy is reviewed. Review the available literature concerning the role of retroperitoneal lymph node dissection and metastasectomy in outcome of oligometastatic RCC. A PubMed search was conducted to identify original articles, review articles, and editorials addressing the role of retroperitoneal lymph node dissection and metastasectomy in outcome of oligometastatic RCC. Keywords included renal tumors, renal cell cancer, kidney cancer, lymphadenectomy, metastasectomy, and oligometastases. While there is no randomized study available, recent large observational studies have better defined the prognosis of patients with metastatic RCC with or without metastasectomy and RPLND. To date, the available evidence suggests that RPLND and metastasectomy may be beneficial when technically feasible in patients with locally advanced (unfavorable clinical and pathologic characteristics) and oligometastatic disease. A proportion of patients will achieve long-term survival with aggressive surgical resection.

Abstract
Aims and background This study aimed to evaluate the significance of characteristics of metastasis as prognostic factors in metastatic renal cell carcinoma (RCC). Patients and methods A total of 148 patients who had received immunotherapy were included in the study. Patients were categorized in various ways according to the characteristics of metastasis, including a synchronous metastasis group (n = 77) vs a metachronous metastasis group (n = 71), and a solitary metastasis group (n = 93) vs a multiple metastases group (n = 55). Results In the synchronous and metachronous metastasis groups, median progression-free survival was 4.3 months (95% confidence interval [CI] 2.9-5.7) and 11.1 months (95% CI 6.7-15.5), respectively (P = 0.004). Median overall survival was 17.1 months (95% CI 9.5-24.7) and 54.8 months (95% CI 38.3-71.3) in the two groups (P = 0.019). In the solitary and multiple metastasis groups, median progression-free survival was 11.0 months (95% CI 6.6-15.5) and 3.9 months (95% CI 2.6-5.2), respectively (P <0.001). Median overall survival was 55.2 months (95% CI 50.7-59.7) and 15.6 months (95% CI 10.9-20.3) in the two groups (P <0.001). Multivariate Cox proportional hazards model analysis using the clinical variables showed that T stage (P = 0.026), number of metastatic sites (P = 0.009) and time to metastasis (P = 0.019) were independent predictors of progression-free survival. Using the same variables, only the number of metastatic sites was an independent prognostic predictor of overall survival (P = 0.014). Conclusions Our findings suggest that the time to metastasis and the number of metastases are important prognostic factors in metastatic RCC.

Abstract
INTRODUCTION Surgery may set the basis for a potential cure or would provide the best achievable quality of life in locally advanced or metastatic renal cell carcinoma (mRCC). However, survival extension with this approach would be scarce and not exempt from adverse events, thus preventing its recommendation in an already frail patient. An evidence based analysis on the role of surgery in each of the possible clinical scenarios involved under this heading may provide a clear picture on this issue and would be of value in the decision making process. Areas covered: Current literature was queried in PubMed/Medline in a systematic fashion. Manuscripts included were selected according to the quality of the data provided. A narrative review strategy was adopted to summarize the evidence acquired. Expert commentary: A surgery-based multimodal treatment approach should be strongly considered after adequate counseling in locally advanced and mRCC, since it may provide for additional benefits in terms of survival. However, a critical reevaluation of its adequacy, optimal timing, and selection of ideal candidates is currently ongoing.

Abstract
Objective To investigate the prognostic value of DNA ploidy, Ki-67 index and p53 expression in relation to disease-related survival in a consecutive series of patients with renal cell carcinoma (RCC). Material and methods The study group consisted of 64 RCC patients treated by radical nephrectomy. Histological type, pathological staging and nuclear anaplasia were assessed according to the WHO classification, TNM system and Fuhrman grading criteria, respectively. Ploidy was determined by DNA flow cytometry using two sampling methods (frozen vs paraffin-embedded tissue). Ki-67 and p53 were evaluated by immunohistochemistry techniques using two cutoff points (10% vs mean value) for staining interpretation. Kaplan-Meier and Cox regression analyses were used for prognostic evaluation. Results Thirty-one tumors (48.4%) showed DNA diploidy and 33 (51.6%) were DNA aneuploid. Concordance between both ploidy measurement methods was found in 85.5% of cases (p=0.0455). The mean values for Ki-67 and p53 immunostaining were 3.65% (0–23.5%) and 5.90% (0–55.9%), respectively. DNA ploidy significantly correlated with staging, tumor size (pT), nuclear grading, and Ki-67 (mean value cutoff). Ki-67 (10% cutoff) correlated with staging and pT, while p53 (mean value cutoff) was associated with Ki-67 (mean value cutoff). There were significant differences between survival curves for pathological stage, pT, nuclear grade, ploidy, Ki-67 (both cutoffs), and p53 (10% cutoff). By univariate regression analysis, stage III and stage IV, pT3, aneuploidy, high Ki-67 (both cutoffs), and p53 overexpression (10% cutoff) showed significant correlations with worse disease-related survival. In addition, DNA aneuploidy significantly correlated with poor prognosis within stages I/II (p=0.0355) and stages III/IV (p=0.0138) of the disease. Conclusion The results indicate that DNA ploidy has relevant prognostic value in RCC, adding useful information to the classic histopathological indicators of clinical outcome.

Abstract
With the ubiquitous use of cross-sectional abdominal imaging in recent years, the incidence of small renal masses (SRMs) has increased, and the evaluation and management of SRMs have become important clinical issues. Diagnosing a mass in the early stages theoretically allows for high rates of cure but simultaneously risks overtreatment. In the past 20 years, surgical treatment of SRMs has transitioned from radical nephrectomy for all renal tumors, regardless of size, to elective partial nephrectomy whenever technically feasible. Additionally, newer approaches, including renal mass biopsy, active surveillance for select patients, and renal mass ablation, have been increasingly used. In this chapter, we review the current evidence-based papers covering aspects of the diagnosis and management of SRMs.

Abstract
Background Partial nephrectomy is considered the preferred care for localized kidney tumors and may yield better patient and kidney survival and similar oncological outcomes compared with radical nephrectomy. We sought to reexamine these hypotheses in a large nationally representative cohort of US veterans who underwent radical or partial nephrectomy. Methods We identified 7073 US veterans who had a partial or radical nephrectomy between 2004 and 2013. We collected data on estimated glomerular filtration rate (eGFR) prior to admission for nephrectomy surgery, immediately after surgery and 180 days postsurgery. We evaluated the association of nephrectomy type and eGFR at different time points with long-term mortality risk in adjusted survival models. Results Patients who underwent radical (compared to partial) nephrectomy had a 2-fold greater decline in eGFR (-21.8 ± 17.7 versus -10.3 ± 17.4 mL/min/1.73 m2) immediately after surgery. This larger drop in eGFR resulted in a larger proportion of radical nephrectomy patients having an eGFR <60 mL/min/1.73 m2 at ≥180 days postsurgery. Radical (compared to partial) nephrectomy patients also exhibited a 2.2-fold higher mortality [adjusted death hazard ratio 2.21 (95% confidence interval 1.91-2.55)]. Low eGFRs prior to surgery and 180 days postsurgery were associated with higher risk of postnephrectomy death. Conclusions Worse postnephrectomy kidney function and higher mortality were observed with radical nephrectomy, and a low presurgical eGFR and a greater decrease in eGFR postsurgery were associated with worse mortality irrespective of the type of nephrectomy. Additional studies are needed to examine predictors of postnephrectomy outcomes.

Abstract
BACKGROUND Surgical tumour removal remains the preferred treatment for most patients with renal cell carcinoma, and many medical associations have proposed guidelines for the optimal surveillance of patients following surgery. This study evaluated the adherence of Canadian urologists to the follow-up guidelines proposed by the Canadian Urological Association (CUA) in 2009. METHODS The study cohort was identified from the Canadian Kidney Cancer Information System, a prospectively populated database from 15 academic institutions in 6 Canadian provinces: British Colombia, Alberta, Manitoba, Ontario, Quebec and Nova Scotia. A total of 1982 patients who underwent radical or partial nephrectomy for stage pT1-3N0M0 renal cancer between January 2011 and June 2016 were included in the cohort. Numbers of abdominal and chest imaging tests performed during the follow-up period were captured and compared with the 2009 CUA guidelines. The level of compliance was measured by means of weighted κ and Pearson correlation statistics. Multivariate logistic regression was used to evaluate factors associated with noncompliance (under- or overtesting) in the postoperative surveillance period. RESULTS Of the 1982 patients, 1380 had stage pT1 disease, 164 had stage pT2 disease, and 438 had stage pT3 disease. There was incongruent adherence to the CUA surveillance guidelines, with a ratio of observed to recommended tests of 0.71 and 2.27 for chest and abdominal imaging, respectively. Overall, moderate correlation between observed and recommended tests was observed, with the highest value found for abdominal imaging in the pT3 group (κ = 0.59 [95% confidence interval 0.52-0.66]). Patients who underwent radical nephrectomy and those who presented with a higher stage of the disease were less likely to receive fewer chest imaging tests than recommended, and those with stage pT2 disease, those with stage pT3 disease, those with conventional clear cell renal cell carcinoma and those with a low-risk histologic type had an increased risk of undertesting. INTERPRETATION In the 6 Canadian provinces, there are large differences between guidelines and clinical practice in imaging surveillance after nephrectomy for renal cell carcinoma. Better adherence to clinical guidelines could improve optimization of health care services.

Abstract
BACKGROUND There are little data regarding the morbidity of lymph node dissection (LND) for renal cell carcinoma (RCC) to assess its risk-benefit ratio. OBJECTIVE To evaluate the association of LND with 30-d complications among patients undergoing radical nephrectomy (RN) for RCC. DESIGN, SETTING, AND PARTICIPANTS A total of 2066 patients underwent RN for M0 or M1 RCC between 1990 and 2010, of whom 774 (37%) underwent LND. INTERVENTION RN with or without LND. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Associations of LND with 30-d complications were examined using logistic regression with several propensity score techniques. Extended LND, defined as removal of ≥13 lymph nodes, was examined in a sensitivity analysis. RESULTS AND LIMITATIONS A total of 184 (9%) patients were pN1 and 302 (15%) were M1. Thirty-day complications occurred in 194 (9%) patients, including Clavien grade ≥3 complications in 81 (4%) patients. Clinicopathologic features were well balanced after propensity score adjustment. In the overall cohort, LND was not statistically significantly associated with Clavien grade ≥3 complications, although there was an approximately 40% increased risk of any Clavien grade complication that did not reach statistical significance. Likewise, LND was not significantly associated with any Clavien grade or Clavien grade ≥3 complications when separately evaluated among M0 or M1 patients. Extended LND was not significantly associated with any Clavien grade or Clavien grade ≥3 complications. LND was not associated with length of stay or estimated blood loss. Limitations include a retrospective design. CONCLUSIONS LND is not significantly associated with an increased risk of Clavien grade ≥3 complications, although it may be associated with a modestly increased risk of minor complications. In the absence of increased morbidity, LND may be justified in a predominantly staging role in the management of RCC. PATIENT SUMMARY Lymph node dissection for renal cell carcinoma is not associated with increased rates of major complications.

Abstract
The comparative effectiveness of partial nephrectomy versus radical nephrectomy to preserve kidney function has not been well established. We determined the risk of clinically significant (stage 4 and higher) CKD after radical or partial nephrectomy among veterans treated for kidney cancer in the Veterans Health Administration (2001-2013). Among patients with preoperative eGFR≥30 ml/min per 1.73 m2, the incidence of CKD stage 4 or higher after radical (n=9759) or partial nephrectomy (n=4370) was 7.9% overall. The median time to stage 4 or higher CKD after surgery was 5 months, after which few patients progressed. In propensity score-matched cohorts, partial nephrectomy associated with a significantly lower relative risk of incident CKD stage 4 or higher (hazard ratio, 0.34; 95% confidence interval [95% CI], 0.26 to 0.43, versus radical nephrectomy). In a parallel analysis of patients with normal or near-normal preoperative kidney function (eGFR≥60 ml/min per 1.73 m2), partial nephrectomy was also associated with a significantly lower relative risk of incident CKD stage 3b or higher (hazard ratio, 0.15; 95% CI, 0.11 to 0.19, versus radical nephrectomy) in propensity score-matched cohorts. Competing risk regression models produced consistent results. Finally, patients treated with a partial nephrectomy had reduced risk of mortality (hazard ratio, 0.55; 95% CI, 0.49 to 0.62). In conclusion, compared with radical nephrectomy, partial nephrectomy was associated with a marked reduction in the incidence of clinically significant CKD and with enhanced survival. Postoperative decline in kidney function occurred mainly in the first year after surgery and appeared stable over time.

Abstract
Background Renal cell carcinoma accounts for approximately 3% of adult malignancies and over 90% of primary renal tumors. Recurrence rates for patients with locally advanced renal cell carcinoma (LARCC) remain high. Methods The authors review literature regarding prognostic factors, potential biomarkers, surgical strategies, and adjuvant therapy trials for patients with LARCC. Results Molecular tumor markers may improve existing staging systems for predicting prognosis. Surgery is the best initial treatment for most patients with clinically localized renal tumors, although complete surgical resection can be challenging for patients with large tumors, bulky regional lymph node involvement, or inferior vena cava tumor thrombus. Significant recurrence rates for patients with LARCC undergoing nephrectomy indicate the presence of undetected micrometastases at the time of surgery. Adjuvant radiation, chemotherapy, and immunotherapy have been ineffective. Other trials of adjuvant therapy are ongoing. Conclusions Aggressive surgical resection alone for LARCC is not sufficient to prevent disease recurrence in a significant number of patients. Adjuvant therapies are needed to improve cancer-specific survival.
