Assessment of Ki-67 proliferation index in prognosis prediction in patients with nonmetastatic clear cell renal cell carcinoma and tumor thrombus. Urol Oncol 2024; 42:23.e5-23.e13. [PMID: 38030468 DOI: 10.1016/j.urolonc.2023.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 10/29/2023] [Accepted: 11/02/2023] [Indexed: 12/01/2023]
Abstract
PURPOSE To determine the optimal cut-off value of Ki-67 for predicting the survival of patients with clear cell renal cell carcinoma (ccRCC) and tumor thrombus and to explore the correlation between Ki-67 expression and pathological features. PATIENTS AND METHODS We retrospectively analyzed Ki-67 immunohistochemical staining of ccRCC and tumor thrombus resected from February 2006 to February 2022. The survival rate was evaluated using the Kaplan-Meier method. The optimal cut-off value of the Ki-67 expression for predicting survival was determined by the minimum P-value method. Clinicopathological data were compared based on Ki-67 status (low versus high expression). Univariate and multivariate Cox regression analysis was used to explore independent predictors. RESULTS A total of 202 patients (median age, 58 years [IQR, 52-65 years], 147 men) with ccRCC and tumor thrombus were included in the study. The optimal cut-off value of Ki-67 for predicting survival was 30%. 159 (78.7%) and 43 (21.3%) patients were included in the low-expression and high-expression groups. Patients with Ki-67 high expression had significantly worse recurrence-free survival (P < 0.001) and cancer-specific survival (P < 0.001). Ki-67 high expression was associated with adverse pathological features, including tumor necrosis, ISUP nuclear grade, sarcomatoid differentiation, perirenal fat invasion, renal pelvis invasion, and inferior vena cava wall invasion (all P < 0.050). Ki-67 expression ≥ 30% (P = 0.016), tumor side (P = 0.003), diabetes (P = 0.040), blood loss (P = 0.016), inferior vena cava wall invasion (P = 0.016), and sarcomatoid differentiation (P = 0.014) were independent predictors of cancer-specific survival. CONCLUSION The optimal cut-off level of Ki-67 in predicting the prognosis of ccRCC and tumor thrombus was 30%. The high expression of Ki-67 was associated with the aggressive pathological phenotype and poor prognosis.

Abstract
BACKGROUND Lymph node invasion is associated with poor outcome in patients with renal cell carcinoma (RCC). PATIENTS AND METHODS Patients with RCC within a single center from 2001 to 2018 were retrospectively obtained from the Chang Gung Research Database. Patient gender, physical status, Charlson Comorbidity Index, tumor side, histology, age at diagnosis, and body mass index (BMI) were compared. The overall survival (OS) and cancer-specific survival (CSS) of each group were estimated using the Kaplan-Meier method. Log-rank tests were used to compare between the subgroups. RESULTS AND CONCLUSIONS A total of 335 patients were enrolled, of whom 76 had pT3N0M0, 29 had pT1-3N1M0, 104 had T1-4N0M1, and 126 had T1-4N1M1 disease. Significant OS difference was noted between pT3N0M0 and pT1-3N1M0 groups with 12.08 years [95% confidence interval (CI), 8.33-15.84] versus 2.58 years (95% CI, 1.32-3.85), respectively (P < 0.005). No significant difference was observed in OS between pT1-3N1M0 and T1-4N0M1 groups with 2.58 years (95% CI, 1.32-3.85) versus 2.50 years (95% CI, 1.85-3.15, P = 0.72). The OS of N1M1 group was worse than that of N0M1 group with 1.00 year (95% CI, 0.74-1.26) versus 2.50 years (95% CI, 1.85-3.15, P < 0.05). Similar results were also observed in CSS. In summary, we claim that RCC with lymph node (LN) invasion should be reclassified as stage IV disease in terms of survival outcome.

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
The role of surgery for patients with locally advanced and metastatic renal cell carcinoma (RCC) is not precisely defined in our contemporary era of systemic therapies. Research in this field is focused on the role of regional lymphadenectomy, along with indications and timing of cytoreductive nephrectomy and metastasectomy. As our understanding of the molecular and immunological basis of RCC continues to develop along with the advent of novel systemic therapies, prospective clinical trials will be critical in defining how surgery should be integrated into the treatment paradigm of advanced RCC.

A Novel Predictive Model of Pathological Lymph Node Metastasis Constructed with Preoperative Independent Predictors in Patients with Renal Cell Carcinoma. J Clin Med 2023; 12:jcm12020441. [PMID: 36675368 PMCID: PMC9866659 DOI: 10.3390/jcm12020441] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 12/21/2022] [Accepted: 12/25/2022] [Indexed: 01/06/2023] Open
Abstract
Introduction: Renal cell carcinoma (RCC) is one of the most common urinary tumors. The risk of metastasis for patients with RCC is about 1/3, among which 30−40% have lymph node metastasis, and the existence of lymph node metastasis will greatly reduce the survival rate of patients. However, the necessity of lymph node dissection is still controversial at present. Therefore, a new predictive model is urgently needed to judge the risk of lymph node metastasis and guide clinical decision making before operation. Method: We retrospectively collected the data of 189 patients who underwent retroperitoneal lymph node dissection or enlarged lymph node resection due to suspected lymph node metastasis or enlarged lymph nodes found during an operation in Tongji Hospital from January 2016 to October 2021. Univariate and multivariate logistic regression and least absolute shrinkage and selection operator (lasso) regression analyses were used to identify preoperative predictors of pathological lymph node positivity. A nomogram was established to predict the probability of lymph node metastasis in patients with RCC before surgery according to the above independent predictors, and its efficacy was evaluated with a calibration curve and a DCA analysis. Result: Among the 189 patients, 54 (28.60%) were pN1 patients, and 135 (71.40%) were pN0 patients. Three independent impact factors were, finally, identified, which were the following: age (OR = 0.3769, 95% CI = 0.1864−0.7622, p < 0.01), lymph node size according to pre-operative imaging (10−20 mm: OR = 15.0040, 95% CI = 1.5666−143.7000, p < 0.05; >20 mm: OR = 4.4013, 95% CI = 1.4892−7.3134, p < 0.01) and clinical T stage (cT1−2 vs. cT3−4) (OR = 3.1641, 95% CI = 1.0336−9.6860, p < 0.05). The calibration curve and DCA (Decision Curve Analysis) showed the nomogram of this predictive model had good fitting. Conclusions: Low age, large lymph node size in pre-operative imaging and high clinical T stage can be used as independent predictive factors of pathological lymph node metastasis in patients with RCC. Our predictive nomogram using these factors exhibited excellent discrimination and calibration.

Abstract
PURPOSE To assess the effect of clinical and pathological variables on cancer-specific and overall survival (OS) in de novo metastatic patients from a collaborative of primarily Latin American countries. PATIENTS AND METHODS Of 4,060 patients with renal cell carcinoma diagnosed between 1990 and 2015, a total of 530 (14.5%) had metastasis at clinical presentation. Relationships between clinical and pathological parameters and treatment-related outcomes were analyzed by Cox regression and the log-rank method. RESULTS Of 530 patients, 184 (90.6%) had died of renal cell carcinoma. The median OS of the entire cohort was 24 months. American Society of Anesthesiology classification 3-4 (hazard ratio [HR]: 1.64), perirenal fat invasion (HR: 2.02), and ≥ 2 metastatic organ sites (HR: 2.19) were independent prognostic factors for 5-year OS in multivariable analyses. We created a risk group stratification with these variables: no adverse risk factors (favorable group), median OS not reached; one adverse factor (intermediate group), median OS 33 months (HR: 2.04); and two or three adverse factors (poor risk group), median OS 14 months (HR: 3.58). CONCLUSION Our study defines novel prognostic factors that are relevant to a Latin American cohort. With external validation, these easily discerned clinical variables can be used to offer prognostic information across low- and middle-income countries.

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.

Reassessment of American Joint Committee on Cancer Staging for Stage III Renal Cell Carcinoma With Nodal Involvement: Propensity Score Matched Analyses of a Large Population-Based Study. Front Oncol 2020; 10:365. [PMID: 32266145 PMCID: PMC7096477 DOI: 10.3389/fonc.2020.00365] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2019] [Accepted: 03/02/2020] [Indexed: 11/24/2022] Open
Abstract
Background: To assess the role of nodal involvement in stage III renal cell carcinoma (RCC) according to the American Joint Committee on Cancer (AJCC) 8th staging system. We compared the survival outcomes of RCC patients with pT1-3N1M0 disease and those with pT3N0M0 or stage IV (stratified as pT4NanyM0 and pTanyNanyM1) disease in a large population-based cohort. Methods: A cohort of 3,112 eligible patients with RCC was identified from the Surveillance, Epidemiology, and End Results (SEER) database, registered between January 2004 and December 2015. Kaplan-Meier and Cox proportional hazards models were used to evaluate the overall survival (OS), and cancer-specific survival (CSS). The prognostic value of the modified stage for pT1-3N1M0 disease was assessed by nomogram-based analyses. Propensity score matching (PSM) was used to adjust for potential baseline confounding. Results: Patients with pT1-3N1M0 disease showed similar survival outcomes (median OS 41.0 vs. 38.0 months, P = 0.77; CSS 45.0 vs. 39.0 months, P = 0.59) to pT4NanyM0 patients, whereas the significantly better survival outcome was found for pT3N0M0 patients. After PSM, comparable survival rates were observed between pT1-3N1M0 group and pT4NanyM0 group, which were still significantly worse than the survival of pT3N0M0 patients. The modified stage IIIA (pT3N0M0), IIIB (pT1-3N1M0, pT4NanyM0), and IV (pTanyNanyM1) showed higher predictive accuracy than AJCC stage system in the nomogram-based analyses (concordance index: 0.70 vs. 0.68, P < 0.001 for OS; 0.71 vs. 0.69, P < 0.001 for CSS). Conclusions: The pT1-3N1M0 RCC might be reclassified as stage IIIB together with pT4NanyM0 disease for better prediction of prognosis, further examination and validation are warranted.

Histotype predicts the rate of lymph node invasion at nephrectomy in patients with nonmetastatic renal cell carcinoma. Urol Oncol 2020; 38:537-544. [PMID: 32122729 DOI: 10.1016/j.urolonc.2020.01.013] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2019] [Revised: 10/15/2019] [Accepted: 01/27/2020] [Indexed: 11/27/2022]
Abstract
BACKGROUND Lymph node invasion (LNI) at nephrectomy is one of the most important predictors of mortality in patients with nonmetastatic renal cell carcinoma (RCC). We analyzed the effect of histology on lymph node metastases at nephrectomy and its effect on survival in a contemporary cohort of patients with nonmetastatic RCC. METHODS Within the Surveillance, Epidemiology, and End Results database (2004-2015), we identified 100,060 patients with clear-cell, papillary, chromophobe, sarcomatoid, and collecting duct RCC, who underwent nephrectomy with or without lymph node dissection for nonmetastatic RCC. Logistic regression models, cumulative incidence plots, and competing-risks regression models were performed. RESULTS Overall, 10,590 patients underwent lymph node dissection for nonmetastatic RCC. Of these, LNI was recorded in 52 (7.0%), 615 (8.7%), 282 (13.9%), 316 (25.1%), 129 (38.3%), 45 (71.4%) patients with chromophobe, clear-cell, nonotherwise specified RCC, papillary, sarcomatoid, and collecting duct RCC histological subtypes, respectively. In logistic regression models, relative to clear-cell, papillary Odds ratio (OR 3.9), sarcomatoid (OR 6.3), collecting duct (OR 14.6) but not chromophobe RCC (OR 0.9; P = 0.5) independently predicted LNI at surgery. Moreover, in competing-risks regression models, LNI increased the risk of CSM 1.8-fold for sarcomatoid, 3.6-fold for clear-cell, 4.1-fold for papillary, and 6.7-fold for chromophobe histological subtype. CONCLUSIONS Histology is an independent predictor of increased risk of LNI at nephrectomy. Moreover, the effect of pathological nodal stage on survival differs according to different histology.

Valuation of lymph node dissection in localized high-risk renal cell cancer using X-tile software. Int Urol Nephrol 2019; 52:253-262. [PMID: 31612422 DOI: 10.1007/s11255-019-02307-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Accepted: 10/09/2019] [Indexed: 02/06/2023]
Abstract
PURPOSE Attempt to group the number of lymph nodes in a more ideal way to assess the value of lymph node dissection (LND) in the treatment of localized high-risk renal cell cancer (LH-RCC). METHODS The Surveillance, Epidemiology, and End Result database (SEER) was used to analyze LH-RCC patients who undergoing radical nephrectomy (RN) from 2011 to 2015. The X-tile software was performed to calculate the optimal grouping cut-off points for the number of removed lymph nodes and positive lymph nodes. The Nomogram model was constructed by R language to visually present survival rates of patients. RESULTS Among 4917 cases of LH-RCC patients undergoing RN, there were 1835 patients treated with LND (37.32%) with the average survival time (AST) of 43.10 months (95% CI 41.91-44.29), which was superior than 40.52 months of patients who did not have LND (95% CI 39.26-41.78) (P < 0.01). The mortality risk of patients with ≥ 3 removed nodes was 0.75 times that of patients with 1-2 removed nodes (95% CI 0.62-0.99, P < 0.01). For overall survival (OS), the hazard ratio of ≥ 5 positive nodes, 1-4 positive nodes, and 0 positive node was 3.04, 2.37, and 1.00, respectively. The Nomogram model can evaluate the 1 year, 2 year, and 3 year survival rates of LH-RCC patients undergoing RN with the internal validation C-index of 0.73. CONCLUSION LH-RCC patients with ≥ 3 removed lymph nodes and fewer positive lymph nodes are expected to have better long-term survival. LND is not only helpful for tumor staging of LH-RCC, but also valuable for long-term survival.

Abstract
OBJECTIVES To develop and externally validate a model that quantifies the likelihood that a pathologically node-negative patient with clear cell renal cell carcinoma (cRCC) has, indeed, no lymph node metastasis (LNM). PATIENTS AND METHODS Data from 1389 patients treated with radical nephrectomy (RN) and lymph node dissection (LND) were analyzed. For external validation, we used data from 2270 patients in the Surveillance, Epidemiology and End Results (SEER) database. We estimated the sensitivity of pathologic nodal staging using a beta-binomial model and developed a pathological nodal staging score (pNSS), which represents the probability that a patient is correctly staged as node negative as a function of the number of examined lymph nodes (LNs). RESULTS The mean and median number of LNs removed were 7.0 and 5.0 (standard deviation, SD 6.6; interquartile range, IQR 7.0) in the development cohort and 5.6 and 2.0 (SD 8.6, IQR 5.0) in the validation cohort, respectively. The probability of missing a positive LN decreased with increasing number of LNs examined. In both the validation and the development cohort, the number of LNs needed for correctly staging a patient as node negative increased with higher pathological tumor stage and Fuhrman grade. CONCLUSIONS The number of examined LNs needed for adequate nodal staging in cRCC depends on pathological tumor stage and Fuhrman grade. We developed here and then externally validated a pNSS, which could help to refine patient counseling, decision-making regarding risk-stratified surveillance regimens and inclusion criteria for clinical trials of adjuvant therapy.

Accuracy of clinical nodal staging and factors associated with receipt of lymph node dissection at the time of surgery for nonmetastatic renal cell carcinoma. Urol Oncol 2019; 37:577.e17-577.e25. [PMID: 31280982 DOI: 10.1016/j.urolonc.2019.06.003] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2018] [Revised: 05/27/2019] [Accepted: 06/05/2019] [Indexed: 01/20/2023]
Abstract
INTRODUCTION The benefit of lymph node dissection (LND) in renal cell carcinoma (RCC) remains poorly defined. Despite this uncertainty, the American Urological Association (AUA) guideline on localized renal cancer recommends that LND be performed for staging purposes when there is suspicion of regional lymphadenopathy on imaging. Using the National Cancer Database (NCDB), we sought to determine how much of a departure the new AUA guideline is from current practice. We hypothesized that practice patterns would reflect the "Expert Opinion" recommendation and that patients who are clinical lymph node (cLN) positive would receive a LND more often than those who are cLN negative. Additionally, we sought to determine factors that would trigger a LND as well the accuracy of clinical staging by examining the relationship between cLN and pathologic lymph node (pLN) status of patients who received a LND. MATERIALS AND METHODS The NCDB was queried for patients with nonmetastatic RCC who underwent partial nephrectomy or nephrectomy from 2010 to 2014. Patient sociodemographic and clinical characteristics were extracted. Frequency distributions were calculated for patients with both cLN and pLN status available. Of patients who received a LND, sensitivity, specificity, and positive/negative predictive values (PPV/NPV) of cLN status for pLN positivity were calculated. Logistic regression models were used to examine association between clinical and socioeconomic factors and receipt of LND. Propensity score matching was used in sensitivity analyses to examine potential for reporting bias in NCDB data. RESULTS We identified 110,963 patients who underwent surgery for RCC, of whom 11,867 (11%) had LND performed at the time of surgery. cLN and pLN information were available in 11,300 patients, of which 1,725 were preoperatively staged as having positive cLN. More LNDs were performed per year for patients who were cLN negative than cLN positive. Of patients who received a LND, the majority of patients were cLN negative across all clinical T (cT) stages. Multivariable analysis showed that all patients who had care at an academic/research institution (odds ratio [OR]: 1.58, 95% confidence interval [CI]: 1.43-1.74) and had to travel >12.5 to 31.0 miles and >31.0 miles to a treatment center (OR: 1.08, 95%CI: 1.01-1.15 and OR: 1.28, 95%CI: 1.20-1.36, respectively) were more likely to get a LND. As cT stage increased from cT2-4, the risk of LND increased (OR range: 4.7-7.90, respectively). Patients who were cLN positive were more likely to receive a LND at the time of surgery (OR: 18.68, 95%CI: 16.62-21.00). Of the patients who received a LND, clinical staging was more specific than sensitive. CONCLUSION More patients received a LND who were cLN negative compared to patients who were cLN positive. Patients who were cLN positive were more likely to receive a LND. Treatment center type, distance to treatment center, cT stage, and cLN positivity were factors associated with LND receipt.

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
OBJECTIVES To assess the relationship between nodal disease burden and overall survival (OS) among patients with lymph node (LN) metastases from renal cell carcinoma (RCC) METHODS: The National Cancer Data Base was used to identify 2,975 patients with RCC who were treated with radical nephrectomy and were found to have regional LN metastases. Associations between the number of positive and negative LN removed and OS were assessed using Cox proportional hazards regression. The median follow-up time among survivors was 3.6years. RESULTS The median number of positive LN was 1 (interquartile range 1-3). A higher number of positive LN was associated with higher all-cause mortality on multivariable analysis (HR 1.06 per 1 positive LN, 95% CI 1.04, 1.07, P < 0.001). Conversely, higher negative LN counts were associated with better OS (HR 0.97 per 1 negative LN, 95% CI 0.96, 0.99, P < 0.001). The adjusted probability of a patient with 1 LN removed that was positive surviving at least 2 years was 56%, a figure that increased to 64% when 1 out of 10 LN removed was positive and decreased to 38% when 10 out of 10 LN removed were positive. CONCLUSIONS Ours is the first study to show that differences in nodal disease burden translate into clinically significant differences in survival among patients with LN metastases from RCC.

Abstract
Background: The role of lymph node dissection (LND) for renal cell carcinoma (RCC) is controversial. Notably, the conflicting evidence on the benefits and harms of LND is inherently linked to the lack of consensus on both anatomic templates and extent of lymphadenectomy. Herein, we provide a detailed overview of the most commonly dissected templates of LND for RCC, focusing on key anatomic landmarks and patterns of lymphatic drainage. Methods: A systematic review of the English-language literature was performed without time filters in July 2018 in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement recommendations. The primary endpoint was to summarize the most commonly dissected templates of LND according to the side of RCC. Results: Overall, 25 studies were selected for qualitative analysis. Of these, most were retrospective. The LND template was heterogeneous across studies. Indications and extent of LND were either not reported or not standardized in most series. The most commonly dissected template for right-sided tumors included hilar, paracaval, and precaval nodes, with few authors extending the dissection to the inter-aortocaval, retrocaval, common iliac or pre/paraaortic nodes. Similarly, the most commonly dissected template for left-sided tumors encompassed the renal hilar, preaortic and paraaortic nodes, with few authors reporting a systematic dissection of inter-aortocaval, retro-aortic, common iliac, or para-caval nodes. Conclusions: In light of the unpredictable renal lymphatic anatomy and the evidence from available prospective mapping studies, the extent of the most commonly dissected templates might be insufficient to catch the overall anatomic pattern of lymphatic drainage from RCC.

The side and the location of the primary tumor does not affect the probability of lymph node invasion in patients with renal cell carcinoma. World J Urol 2018; 37:1623-1629. [PMID: 30474699 DOI: 10.1007/s00345-018-2573-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2018] [Accepted: 11/20/2018] [Indexed: 10/27/2022] Open
Abstract
PURPOSE To evaluate the role of side and location of the primary renal cell carcinoma (RCC) on the risk of lymph node invasion (LNI) and/or nodal progression (NP) during follow-up. MATERIALS AND METHODS We evaluated 2485 patients with unilateral RCC, surgically treated in a single tertiary care referral center. Outcomes were LNI at surgery and/or NP during follow-up. We studied if RCC side (left vs. right) and location (upper vs. middle vs. hilar vs. lower area vs. more than one area) affected the probability of LNI and/or NP at follow-up. RESULTS Overall, 43 and 15% of patients underwent lymph node dissection and had LNI at surgery, respectively. During follow-up, 2.2% of patients had NP. Higher rates of LNI and NP were observed for patients with primary tumor located in more than one anatomical kidney area relative to patients with tumor in a single area (upper 11% vs. middle 10% vs. hilar 0%, vs. lower 12% vs. more than one area 26%, p < 0.01). cM1, cN1, pT2/pT3/pT4 disease and Fuhrman grade 3/4 were independent predictors of the study outcome (all p ≤ 0.01). Neither the RCC side nor the location reached the independent predictor status (all p > 0.1). CONCLUSIONS Patients with single-side and more than one anatomical kidney area affected by RCC have higher rate of LNI at surgery and/or NP at follow-up. Neither side nor location of primary RCC tumor is related to the risk of harboring LNI at surgery and/or developing NP at follow-up.

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.

The Effect of Anatomical Location of Lymph Node Metastases on Cancer Specific Survival in Patients with Clear Cell Renal Cell Carcinoma. Front Surg 2018; 5:26.

Abstract
Background Positive nodal status (pN1) is an independent predictor of survival in renal cell carcinoma (RCC) patients. However, no study to date has tested whether the location of lymph node (LN) metastases does affect oncologic outcomes in a population submitted to radical nephrectomy (RN) and extended lymph node dissection (eLND). Objective To describe nodal disease dissemination in clear cell RCC (ccRCC) patients and to assess the effect of the anatomical sites and the number of nodal areas affected on cancer specific mortality (CSM). Design, setting and partecipants The study included 415 patients who underwent RN and eLND, defined as the removal of hilar, side-specific (pre/paraaortic or pre/paracaval) and interaortocaval LNs for ccRCC, at two institutions. Outcome measurement and statistical analysis Descriptive statistics were used to depict nodal dissemination in pN1 patients, stratified according to nodal site and number of involved areas. Multivariable Cox regression analyses and Kaplan-Meier curves were used to explore the relationship between pN1 disease features and survival outcomes. Results and limitations Median number of removed LN was 14 (IQR 9–19); 23% of patients were pN1. Among patients with one involved nodal site, 54 and 26% of patients were positive only in side-specific and interaortocaval station, respectively. The most frequent nodal site was the interaortocaval and side-specific one, for right and left ccRCC, respectively. Interaortocaval nodal positivity (HR 2.3, CI 95%: 1.3–3.9, p < 0.01) represented an independent predictor of CSM. Conclusions When ccRCC patient harbour nodal disease, its spreading can occur at any nodal station without involving the others. The presence of interoartocaval positive nodes does affect oncologic outcomes. Patient summary Lymph node invasion in patients with clear cell renal cell carcinoma is not following a fixed anatomical pattern. An extended lymph node dissection, during treatment for primary kidney tumour, would aid patient risk stratification and multimodality upfront treatment.

Abstract
Our objective was to evaluate the role of retroperitoneal lymph node dissection (LND) in non-metastatic (M0) and metastatic (M1) renal cell carcinoma (RCC). We searched Medline, EMBASE, Web of Science and Scopus from database inception to 29 August 2017 for studies of patients who underwent partial or radical nephrectomy for M0 or M1 RCC. Two investigators independently selected studies for inclusion. Risk of bias was assessed using the Newcastle-Ottawa scale, Cochrane Collaboration tool and National Heart, Lung and Blood Institute Quality Assessment Tool. Random effects meta-analysis was performed for all-cause-mortality. The GRADE approach was used to characterize quality of evidence. A total of 51 unique studies were included in the qualitative systematic review. Risk of bias was low in 41/51 (80%) studies. LND was not associated with all-cause mortality in either M0 (hazard ratio [HR] 1.02, 95% confidence interval [CI] 0.92-1.12; I2 = 0%; four studies), M1 (HR 1.04, 95% CI 0.83-1.29; I2 = 0%; two studies), or pooled M0 and M1 settings (HR 1.00, 95% CI 0.92-1.09; I2 = 0%; seven studies), with no statistically significant differences according to M stage subgroups (P = 0.50). In the three studies that examined M0 subgroups with a high risk of nodal metastasis, LND was not associated with improved oncological outcomes. Studies on the association of extent of LND with survival reported inconsistent results. Meanwhile, a small proportion of patients with pN1M0 disease demonstrate durable long-term oncological control after surgery, with 10-year cancer-specific survival of 21-31%. Nodal involvement is independently associated with adverse prognosis in both M0 and M1 settings. GRADE quality of evidence was moderate or low for the outcomes examined. Although LND yields independent prognostic information, the existing literature does not support a therapeutic benefit to LND in either M0 or M1 RCC. High-risk M0 patient groups warrant further study, as a subset of patients with isolated nodal metastases experience long-term survival after surgical resection.

Abstract
PURPOSE To determine the therapeutic value of lymph node dissection (LND) during cytoreductive nephrectomy (CN) and assess predictors of cancer-specific survival (CSS) in metastatic renal-cell carcinoma. PATIENTS AND METHODS We identified 293 consecutive patients treated with CN at 4 academic institutions from March 2000 to May 2015. LND was performed in 187 patients (63.8%). CSS was estimated by the Kaplan-Meier method for the entire cohort and for a propensity score-matched cohort. Cox proportional hazards regression was used to evaluate CSS in a multivariate model and in an inverse probability weighting-adjusted model for patients who underwent dissection. RESULTS Median follow-up was 12.6 months (interquartile range, 4.47, 30.3), and median survival was 15.9 months. Of the 293 patients, 187 (63.8%) underwent LND. One hundred six patients had nodal involvement (pN+) with a median CSS of 11.3 months (95% confidence interval [CI], 6.6, 15.9) versus 24.2 months (95% confidence interval, 14.1, 34.3) for pN- patients (log-rank P = .002). The hazard ratio for LND was 1.325 (95% CI, 1.002, 1.75) for the whole cohort and 1.024 (95% CI, 0.682, 1.537) in the propensity score-matched cohort. Multivariate analysis revealed that number of positive lymph nodes (P < .001) was a significant predictor of worse CSS. CONCLUSION For patients with metastatic renal-cell carcinoma undergoing CN with lymphadenectomy, the number of nodes positive was predictive of survival at short-term follow-up. However, nonstandardized lymphadenectomy only provided prognostic information without therapeutic benefit. Prospective studies with standardized templates are required to further ascertain the therapeutic value of LND.

Lymph node dissection should not be dismissed in case of localized renal cell carcinoma in the presence of larger diseases. Urol Oncol 2017; 35:662.e9-662.e15.

Abstract
OBJECTIVE To assess whether even in the group of localized renal cell carcinoma (RCC), some patients might harbor a disease with a predilection for lymph node invasion (LNI) and/or lymph node (LN) progression and might deserve lymph node dissection (LND) at the time of surgery. MATERIALS AND METHODS Between 1990 and 2014, 2,010 patients with clinically defined T1-T2N0M0 RCC were treated with nephrectomy and standardized LND at a single tertiary care referral center. The endpoint consists of the presence of LNI and/or nodal progression, defined as the onset of a new clinically detected lymphadenopathy (>10mm) in the retroperitoneal lymphatic area with associated systemic progression or histological confirmation or both. We tested the association between clinical characteristics and the endpoint of interest. Predictors consisted of age at surgery, clinical tumor size, preoperative hemoglobin, and platelets levels. Multivariable logistic regression model and smoothed Lowess method were used. RESULTS LNI was recorded in 14 cases (2.2%). The median follow-up after surgery was 68 months. During the study period, 23 patients (1.1%) experienced LN progression; 91% of those patients experienced LN progression within 3 years after surgery. Combining the 2 endpoints, 36 patients (1.8%) had LNI and/or LN progression. Clinical tumor size was the only independent predictors of LNI and/or LN progression (OR = 1.25). A significant increase of the risk of LNI and/or LN progression was observed in RCC larger than 7cm (cT2a or higher). CONCLUSIONS LNI and/or LN progression is a rare entity in patients with localized RCC. Nonetheless, patients with larger tumors might still benefit from LND because of a non-negligible risk of LNI and/or LN progression.

Abstract
Introduction Lymphadenectomy (LND) has recently attracted considerable interest from urological surgeons, as extended lymphadenectomy might have a role in accurate staging or improving patient survival in those patients with urological malignancies. Upper tract urothelial carcinoma (UTUC) is a relatively rare neoplasm, accounting for about 5% of all urothelial cancers. Up to 30% of patients with muscle-invasive UTUC have metastasis in the regional lymph nodes (LNs), which represents a well-established poor prognostic factor. Material and methods A medline search was conducted to identify original articles and review articles addressing the role of lymphadenectomy LND in UTUC. Keywords included lymphadenectomy, lymph node excision, nephroureterectomy, and upper tract urothelial carcinoma. Results LND instead of lymphadenectomy has recently attracted considerable interest from urological surgeons and might have a potential role in improving the oncological outcome in patients with urothelial carcinoma. LND ideally improves disease staging; thereby, we need to find the way to identify the patients who could really benefit from adjuvant systemic theraphy. Template-based LND with Radical Nephroureterectomy (RNU) for high risk disease is gaining support based on accumulating retrospective data and supports its utility as a potentially therapeutic maneuver. RNU is still the gold standard treatment for UTUC, but minimal invasive procedures such as laparoscopic RNU and Robot Assisted Nephroureterectomy (RANU) are becoming more employed in recent years and should be used by expert hands. Conclusions Therapeutic benefits of LND and nodal status on disease free survival (DFS) and Cancer Free Survival (CSS) remains controversial. Although most of the data comes from retrospective studies, we encourage performing well designed, prospective, and multicentre studies to clarify this in the coming years.

Abstract
OBJECTIVES Staging for renal cell carcinoma (RCC) depends on tumor size and the status of the regional lymph nodes. Although lymph node involvement by tumor yields the most accurate staging and prognostic information in patients with carcinomas of various genitourinary organs, the role of lymph node sampling (LNS) in patients with RCC to definitively establish nodal metastases remains unsettled. METHODS In this retrospective study of 399 patients with RCC treated by total nephrectomy, 115 cases were subjected to lymph node dissection. RESULTS The corresponding primary tumors averaged larger than 8 cm. Twenty-nine showed positive lymph nodes (25%). The present review confirms that primary tumor size is a key indicator of nodal involvement. Clear cell and papillary tumors larger than 4 cm involve lymph nodes more commonly than other types of RCC. Sarcomatoid differentiation occurred in all major cell types and existed in numbers too few to predict the likelihood of nodal metastases. CONCLUSIONS LNS in RCC for staging purposes may be warranted based on tumor size (>4 cm) as determined by imaging as well as histologic cell type, the latter suggesting a selective role for preoperative fine needle aspiration or core biopsy.

Abstract
Sentinel lymph node biopsy (SLNB) is now an established technique in penile and pelvic cancers, resulting in a lower mortality and morbidity when compared with the traditional lymph node dissection. In renal cancer however, despite some early successes for the SLNB technique, paucity of data remains a problem, thus lymph node dissection and extended lymph node dissection remain the management of choice in clinically node positive patients, with surveillance of lymph nodes in those who are clinically node negative. SLNB is a rapidly evolving technique and the introduction of new techniques such as near infra-red fluorescence optical imaging agents and positron emission tomography/computed tomography scans, may improve sensitivity. Evidence in support of this has already been recorded in bladder and prostate cancer. Although the lack of large multi-centre studies and issues around false negativity currently prevent its widespread use, with evolving techniques improving accuracy and the support of large-scale studies, SLNB does have the potential to become an integral part of staging in renal malignancy.

Abstract
BACKGROUND It is unknown whether lymph node metastases (LNM) and their localization negatively affect clinical outcome in metastatic renal cell carcinoma (mRCC) patients. OBJECTIVE To evaluate the clinicopathological features, survival outcome, and treatment response in mRCC patients with LNM versus those without LNM after treatment with targeted therapies (TT). DESIGN, SETTING, AND PARTICIPANTS Patients (n=2996) were first analyzed without consideration of lymph node (LN) localization or histologic subtype. Additional analyses (n=1536) were performed in subgroups of patients with supradiaphragmatic (SPD) LNM, subdiaphragmatic (SBD) LNM, and patients with LNM in both locations (SPD+/SBD+) without histologic considerations, and then separately in clear cell RCC (ccRCC) and non-clear cell RCC (nccRCC) patients, respectively. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The primary outcome was overall survival (OS) and the secondary outcome was progression-free survival (PFS). RESULTS AND LIMITATIONS All patients with LNM had worse PFS (p=0.001) and OS (p<0.001) compared to those without LNM. Compared to patients without LNM (PFS 8.8 mo; OS 25.1 mo), any SBD LNM involvement was associated with worse PFS (SBD, 6.8 mo; p=0.003; SPD+/SBD+, 5.5 mo; p<0.001) and OS (SBD, 16.2 mo; p<0.001; SPD+/SBD+, 11.5 mo; p<0.001). Both SBD and SPD+/SBD+ LNM were retained as independent prognostic factors in multivariate analyses (MVA) for PFS (p=0.006 and p=0.022, respectively) and OS (both p<0.001), while SPD LNM was not an independent risk factor. Likewise, in ccRCC, SBD LNM (19.8 mo) and SPD+/SBD+ LNM (12.85 mo) patients had the worst OS. SPD+/SBD+ LNM (p=0.006) and SBD LNM (p=0.028) were independent prognostic factors for OS in MVA, while SPD LNM was not significant (p=0.301). The study is limited by its retrospective design and the lack of pathologic evaluation of LNM in all cases. CONCLUSIONS The metastatic spread of RCC to SBD lymph nodes is associated with poor prognosis in mRCC patients treated with TT. PATIENT SUMMARY The presence of lymph node metastases below the diaphragm is associated with shorter survival outcome when metastatic renal cell carcinoma (mRCC) patients are treated with targeted therapies. Clinical trials should evaluate whether surgical removal of regional lymph nodes at the time of nephrectomy may improve outcomes in high-risk RCC patients.

Abstract
Lymphatic drainage in renal cell carcinoma (RCC) is unpredictable, however, basic patterns can be observed in cadaveric and sentinel lymph node mapping studies in patients with RCC. The existence of peripheral lymphovenous communications at the level of the renal vein has been shown in mammals but remains unknown in humans. The sentinel lymph node biopsy technique can be safely applied to map lymphatic drainage patterns in patients with RCC. Further standardisation of sentinel node biopsy techniques is required to improve the clinical significance of mapping studies. Understanding lymphatic drainage in RCC may lead to an evidence-based consensus on the surgical management of retroperitoneal lymph nodes.

Abstract
Surgical resection of renal cell carcinoma (RCC) is the benchmark for long-term cure of the disease. Although open or laparoscopic radical nephrectomy is considered the gold standard for stage T1b-T4 tumors, nephron-sparing surgery is the preferred operative modality for small renal masses demonstrating equivalent oncologic efficacy and improved renal function outcomes compared with complete nephrectomy. With the advance of minimally invasive surgery, nephron-sparing procedures can safely be conducted laparoscopically with or without robotic assistance. RCC with intravenous tumor thrombus presents a surgical challenge, but multidisciplinary surgical approaches can provide long-term benefit in these patients. The role of cytoreductive nephrectomy and metastasectomy in patients with metastatic RCC (mRCC) is controversial, but seems to be beneficial for patients in the era of targeted therapy.

Abstract
PURPOSE To analyze the role of lymph node dissection (LND) in patients with large renal tumors. METHODS We performed a retrospective study of patients with renal cell carcinoma ≥7 cm in size undergoing surgery between 1990 and 2012. Primary outcome measures were recurrence-free and overall survival of patients who did and did not undergo LND. Cox proportional hazards regression models were created to account for known risk factors for recurrence and survival. Secondary outcomes were recurrence-free and overall survival by lymph node status, lymph node template and number of lymph nodes removed. RESULTS Of 524 patients, 164 had disease recurrence and 197 died. Median follow-up was 5 and 5.5 years for patients who did not die or have a recurrence, respectively. A total of 334 (64 %) patients underwent LND, and node-positive disease was identified in 26 (8 %). For patients who did and did not undergo LND, 5-year recurrence-free survival was 64 and 77 %, respectively. Five-year overall survival was 75 and 78 %, respectively. LND was not a predictor of recurrence or survival in multivariate analysis. Node-positive disease was associated with recurrence (p < 0.0005) and mortality (p = 0.032), although node-positive patients had a 5-year overall survival of 65 %. CONCLUSIONS We did not find a difference in recurrence-free or overall survival in patients with ≥7-cm tumors whether or not they underwent LND. Node-positive disease was associated with worse outcomes, suggesting that LND provides important staging information that can be important in the design of adjuvant clinical trials.

Abstract
Renal cell carcinoma (RCC) is the most deadly of urological malignancies. Metastatic disease affects one third of patients at diagnosis with a further third developing metastatic disease after extirpative surgery. Heterogeneity in the clinical course ensures predicting metastasis is notoriously difficult, despite the routine use of prognostic clinico-pathological parameters in risk stratification. With greater understanding of pathways involved in disease pathogenesis, a number of biomarkers have been shown to have prognostic significance, including Ki67, p53, vascular endothelial growth factor receptor 1 (VEGFR1) and ligand D (VEGFD), SNAIL and SLUG. Previous pathway analysis has been from study of the primary tumour, with little attention to the metastatic tumours which are the focus of targeted molecular therapies. As such, in this study a tissue microarray from 177 patients with primary renal tumour, renal vein tumour thrombus and/or RCC metastasis has been created and used with Automated Quantitative Analysis (AQUA) of immunofluorescence to study the prognostic significance of these markers in locally advanced and metastatic disease. Furthermore, this has allowed assessment of differential protein expression between the primary tumours, renal vein tumour thrombi and metastases. The results demonstrate that clinico-pathological parameters remain the most significant predictors of cancer specific survival; however, high VEGFR1 or VEGFD can predict poor cancer specific survival on univariate analysis for locally advanced and metastatic disease. There was significantly greater expression of Ki67, p53, VEGFR1, SLUG and SNAIL in the metastases compared with the primary tumours and renal vein tumour thrombi. With the exception of p53, these differences in protein expression have not been shown previously in RCC. This confirms the importance of proliferation, angiogenesis and epithelial to mesenchymal transition in the pathogenesis and metastasis of RCC. Importantly, this work highlights the need for further pathway analysis of metastatic tumours for overcoming drug resistance and developing new therapies.

Abstract
Background Controversies exist regarding the effect of lymphadenectomy (LND) in renal cell carcinoma (RCC). We hypothesized that patients with locally advanced cancer invading beyond Gerota's fascia (pT4 Nany Many RCC) might benefit from an extended LND not only for staging but also for survival purposes. Materials and Methods Clinical and pathologic data were prospectively gathered in 1.847 patients treated at a single Academic Center, between 1987 and 2011. Only patients with pT4 RCC (TNM 2009, n=44, 2.4%) were included. Univariable (UVA) and multivariable (MVA) Cox regression analyses targeted the association between the number of lymph nodes removed and cancer specific mortality (CSM). Analyses were adjusted for age, Fuhrman grade, symptoms at presentation, metastases at diagnosis, ECOG performance status, tumor size, number of positive nodes, and presence of necrosis or sarcomatoid features. Results Mean number of nodes removed was 11.8 (median 8, range 1–37). Mean number of positive nodes was 4.8 (median 2, range 0–36). Cancer-specific survival rates at 1, 2 and 3 years of follow-up were 39.3%, 25.0% and 8.6%, respectively. When stratified for nodal status, cancer-specific survival rates at 1, 2 and 3 years of follow-up were 65.0, 36.1, and 9.0% vs. 13.3, 13.0, and 6.7%, for pN0 vs. pN+ cases, respectively (p=0.004). At MVA, after adjusting for all the possible confounders, the number of positive nodes resulted independently associated with CSM (HR 1.25, p=0.001). Interestingly, at MVA, the number of nodes removed achieved the independent predictor status, as well (HR 0.84, p=0.007) showing a protective effect on survival. The risk of dying increased of 16% every positive node found (p<0.001), and decreased of 8% every node removed (p=0.02) (Table II). Conclusions A more extended retroperitoneal lymphadenectomy at the time of nephrectomy statistically significantly decreased CSM in pT4 cases.

Abstract
UNLABELLED WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: In renal cell carcinoma the role of lymphadenectomy (LND) is still controversial. Moreover, no firm consensus exists regarding the minimum number of lymph nodes that should be removed to obtain a satisfactory staging LND at the time of surgery. Our findings demonstrate that, when clinically indicated, staging LND in renal cell carcinoma should be extended. The removal of 15 lymph nodes might represent the lowest threshold to define a staging LND as adequate. More extended LND should be pursued if unfavourable clinical and pathological characteristics are evident at diagnosis and/or during surgery. OBJECTIVE To investigate the staging of lymphadenectomy in renal cell carcinoma. No convincing data exist regarding the minimum number of lymph nodes that should be removed at the time of nephrectomy to ensure an accurate staging. METHODS Between 1987 and 2011, 850 patients with renal cell carcinoma underwent either partial or radical nephrectomy plus lymph node dissection (LND) at a single tertiary care institution (Tany N0-1Many ). Receiver operating characteristic curve coordinates were used to graph the probability of finding lymph node invasion according to the number of removed lymph nodes. Assuming that the likelihood of finding lymph node invasion according to the number of lymph nodes removed may be affected by patient characteristics, analyses were further stratified for clinical and pathological characteristics. RESULTS The rate of lymph node metastases strongly correlated with the clinical and pathological characteristics of the patients. Fifteen lymph nodes need to be removed to achieve a 90% probability of detecting at least one metastatic lymph node. Only slight differences were recorded after stratification for clinical nodal status, the presence of metastases at diagnosis and pathological T stage. Finally, 13, 16 and 21 lymph nodes need to be removed to achieve a 90% probability of detecting lymph node invasion, if present, in the low risk (score 0-1), intermediate risk (score 2-3) and high risk (score 4-5) Mayo Clinic classification, respectively. CONCLUSION The removal of 15 lymph nodes represents the lowest threshold for considering a staging LND as adequate. More extended LND should be pursued if unfavourable clinical and pathological characteristics are evident at diagnosis and/or during surgery.

Abstract
The role of lymphadenectomy has been controversial in urological malignancies. Urothelial carcinoma of the bladder and upper urinary tract has a high potential to spread through the lymphatic network compared with other malignancies, including renal cell carcinoma or prostate cancer. In urothelial carcinoma of the bladder, lymphadenectomy of pelvic nodes had been considered as the standard procedure when radical cystectomy was carried out. Recently, many investigators have examined the influence of its extent, and the majority of the studies have supported the beneficial role of extended lymphadenectomy in accurate staging or in improving patient survival. Although randomized controlled trials are required to establish a greater level of evidence, more urological surgeons have already noticed the necessity for extended lymphadenectomy in bladder cancer. In contrast to bladder cancer, there have been far fewer studies on urothelial carcinoma of the upper urinary tract. This might be because of the smaller number of the patients with urothelial carcinoma of the upper urinary tract and the lack of understanding of regional nodes. However, studies of lymph node mapping and the retrospective analyses with respect to the benefit of lymphadenectomy have been carried out in urothelial carcinoma of the upper urinary tract by some investigators, although the results are still controversial. However, the results from multi-institutional studies by high volume centers have supported the beneficial role of lymphadenectomy in urothelial carcinoma of the upper urinary tract, as it has been proposed in bladder cancer. Thus, lymphadenectomy for urothelial carcinoma of the bladder and the upper urinary tract might have a potential role in staging and improving the oncological outcomes.

Abstract
The role of lymph node dissection (LND) in the staging and treatment of renal cell carcinoma has long been a topic of debate. The controversy has focused on whether LND is purely an adjunctive staging procedure or has a therapeutic role in the management of this disease. Potential benefits include enhanced staging, better selection for adjuvant therapies/clinical trials, a decrease in recurrence rates, and improved disease-specific and overall survival. This article reviews the available literature on LND in renal cell carcinoma and discusses the potential benefits of aggressive surgical resection in select high-risk patients.

Abstract
UNLABELLED Nodal metastases, even in the absence of distant metastases, portend a bad prognosis. The percentage of positive nodes (PPN) represents an important predictor of cancer-specific mortality (CSM) in patients in the group T(any) N(1) M(0) . In consequence, universal inclusion of PPN should be considered in prospective and retrospective CSM analyses. OBJECTIVES To examine the outcomes of patients with node-positive renal cell carcinoma (RCC) in the absence of distant metastases in a large population-based cohort of patients To examine the ability of standard risk factors to predict cancer-specific mortality (CSM). PATIENTS AND METHODS Using the Surveillance, Epidemiology, and End Results database, a total of 799 patients with RCC nodal metastases and absence of distant metastases undergoing nephrectomy were identified. Univariable and multivariable analyses was performed with the aim of identifying independent predictors of CSM in this cohort of patients. Specifically, we examined the effect of the number of removed nodes (NRN), the number of positive nodes (NPN) and the percentage of positive nodes (PPN) on CSM. RESULTS Actuarial survival estimates showed that 53.2, 37.8 and 25.7% of patients survived at 24, 60 and 120 months after nephrectomy. In Kaplan-Meier analyses, NRN failed to clearly discriminate between recorded CSM rates (log rank P = 0.07). Discrimination was noted when CSM was stratified according to NPN (log rank P = 0.02) and PPN (log rank P = 0.001). In multivariable analyses, age, Fuhrman grade, histological subtype, T stage and PPN were independent predictors of CSM. CONCLUSIONS Our data indicate that CSM of patients with exclusive nodal metastases differs according to PPN. Consequently, PPN warrants consideration in future prognostic schemes.

Abstract
CONTEXT Although lymphadenectomy (lymph node dissection [LND]) is currently accepted as the most accurate and reliable staging procedure for the detection of lymph node invasion (LNI), its therapeutic benefit in renal cell carcinoma (RCC) still remains controversial. OBJECTIVE Review the available literature concerning the role of LND in RCC staging and outcome. EVIDENCE ACQUISITION A Medline search was conducted to identify original articles, review articles, and editorials addressing the role of LND in RCC. Keywords included kidney neoplasms, renal cell cancer, renal cell carcinoma, kidney cancer, lymphadenectomy, lymph node excision, lymphatic metastases, nephrectomy, imaging, and complications. The articles with the highest level of evidence were identified with the consensus of all of the collaborative authors and were critically reviewed. This review is the result of an interactive peer-reviewing process by an expert panel of co-authors. EVIDENCE SYNTHESIS Renal lymphatic drainage is unpredictable. The newer available imaging techniques are still immature in detecting small lymph node metastases. Results from the European Organization for Research and Treatment of Cancer trial 30881 showed no benefit in performing LND during surgery for clinically node-negative RCC, but the results are limited to patients with the lowest risk of developing LNI. Numerous retrospective series support the hypothesis that LND may be beneficial in high-risk patients (clinical T3-T4, high Fuhrman grade, presence of sarcomatoid features, or coagulative tumor necrosis). If enlarged nodes are evident at imaging or palpable during surgery, LND seems justified at any stage. However, the extent of the LND remains a matter of controversy. CONCLUSIONS To date, the available evidence suggests that an extended LND may be beneficial when technically feasible in patients with locally advanced disease (T3-T4) and/or unfavorable clinical and pathologic characteristics (high Fuhrman grade, larger tumors, presence of sarcomatoid features, and/or coagulative tumor necrosis). Although node-positive patients often harbor distant metastases as well, the majority of retrospective nonrandomized trials seem to suggest a possible benefit of regional LND even for this group of patients. In patients with T1-T2, clinically negative lymph nodes and absence of unfavorable clinical and pathologic characteristics, regional LND offers limited staging information and no benefit in terms of decreasing disease recurrence or improving survival.
