Long-Term Oncologic Outcomes of Off-Clamp Robotic Partial Nephrectomy for Cystic Renal Tumors: A Propensity Score Matched-Pair Comparison of Cystic versus Pure Clear Cell Carcinoma. Curr Oncol 2024; 31:2985-2993.

Abstract
Few data are available on survival outcomes of partial nephrectomy performed for cystic renal tumors. We present the first long-term oncological outcomes of cystic (cystRCC) versus pure clear cell renal cell carcinoma (ccRCC) in a propensity score-matched (PSM) analysis. Our "renal cancer" prospectively maintained database was queried for "cystRCC" or "ccRCC" and "off-clamp robotic partial nephrectomy" (off-C RPN). The two groups were compared for age, gender, tumor size, pT stage, and Fuhrman grade. A 1:3 PSM analysis was applied to reduce covariate imbalance to <10% and two homogeneous populations were generated. Student t- and Chi-square tests were used for continuous and categorical variables, respectively. Ten-year oncological outcomes were compared between the two cohorts using log-rank test. Univariable Cox regression analysis was used to identify predictors of disease progression after RPN. Out of 859 off-C RPNs included, 85 cases were cystRCC and 774 were ccRCC at histologic evaluation. After applying the PSM analysis, two cohorts were selected, including 64 cystRCC and 170 ccRCC. Comparable 10-year cancer-specific survival probability (95.3% versus 100%, p = 0.146) was found between the two cohorts. Conversely, 10-year disease-free survival probability (DFS) was less favorable for pure ccRCC than cystRCC (66.69% versus 90.1%, p = 0.035). At univariable regression analysis, ccRCC histology was the only independent predictor of DFS probability (HR 2.96 95% CI 1.03-8.47, p = 0.044). At the 10-year evaluation, cystRCC showed favorable oncological outcomes after off-C RPN. Pure clear cell variant histology displayed a higher rate of disease recurrence than cystic lesions.

Oncological and functional outcomes of patients who underwent open partial nephrectomy for kidney tumor. Arch Ital Urol Androl 2023; 95:12130. [PMID: 38193219 DOI: 10.4081/aiua.2023.12130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Accepted: 12/02/2023] [Indexed: 01/10/2024] Open
Abstract
OBJECTIVE To report long-term functional and oncological outcomes of OPN Methods: We enrolled 182 patients who underwent consecutive OPN with a diagnosis of kidney tumor in our clinic between April 2002 and February 2020 and were selected from our prospective OPN database. Preoperative demographic and clinical characteristics, intraoperative and pathological results, and patients' postoperative functional and oncological follow-up data were retrospectively analyzed. Overall survival (OS) and disease- free survival (DFS) were evaluated using Kaplan-Meier survival analysis. The time-dependent variation between preoperative and postoperative functional results was statistically analyzed and presented in a graph. RESULTS AND LIMITATIONS The mean age was 54.4 ± 10.8 yr, and the median age-adjusted Charlson comorbidity index (ACCI) was 1 (interquartile range [IQR] 0-1). The mean tumor size was 3.1 ± 1.2 cm, and the median RENAL score was 6 (IQR 5-8). The most common malign histopathological subtype was clear cell carcinoma with 76.6%, and five cases (3.4%) had positive surgical margins (PSMs). The most common surgical techniques were the retroperitoneal approach (98.9%) and cold ischemia (88.5%). Estimated glomerular filtration rate (eGFR) preservation was 92% (80.8-99.3, IQR), which translates to 32% chronic kidney disease (CKD) upstaging. Acute kidney injury (AKI) was detected in 27 (14.8%) patients according to RIFLE criteria. The intraoperative complication rate was 5.5%, and the postoperative overall complication rate (Clavien-Dindo 1-5) was 30.2%. Major complications (Clavien-Dindo 3-5) were observed in 13 (7.1%) patients. The median oncological follow-up was 42 mo (21.3- 84.6, IQR), and the 5- and 10-yr OS were 90.1% and 78.6%, 5 and 10-yr DFS were 99.4% and 92.1%, respectively. No local recurrence was observed in 5 (3.4%) patients with PSMs; only one had distant metastasis in the 8th postoperative month. The retrospective design, the small number of patients who underwent PN based on mandatory indication, and one type of surgical approach may limit the generalizability of our findings. CONCLUSIONS This study confirms excellent long-term oncologic and functional outcomes after OPN in a cohort of patients selected from a single institution. In light of the information provided by the literature and our study, our recommendation is to push the limits of PN under every technically feasible condition in the treatment of kidney tumors to protect the kidney reserve and achieve near-perfect oncological results.

Abstract
OBJECTIVES This study aims to develop and evaluate the deep learning-based classification model for recognizing the pathology of renal tumor from macroscopic cross-section image. METHODS A total of 467 pathology-confirmed patients who received radical nephrectomy or partial nephrectomy were retrospectively enrolled. The experiment of distinguishing malignant and benign renal tumor are conducted followed by performing the multi-subtypes classification models for recognizing four subtypes of benign tumor and four subtypes of malignant tumors, respectively. The classification models used the same backbone networks which are based on the convolutional neural network (CNN), including EfficientNet-B4, ResNet-18, and VGG-16. The performance of the classification models was evaluated by area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy. Besides, we performed the quantitative comparison among these CNN models. RESULTS For the model to differentiate the malignant tumor from the benign tumor, three CNN models all obtained relatively satisfactory performance and the highest AUC was achieved by the ResNet-18 model (AUC = 0.9226). There is not statistically significance between EfficientNet-B4 and ResNet-18 architectures and both of them are significantly statistically better than the VGG-16 model. The micro-averaged AUC, macro-averaged sensitivity, macro-averaged specificity, and micro-averaged accuracy for the VGG-16 model to distinguish the malignant tumor subtypes achieved 0.9398, 0.5774, 0.8660, and 0.7917, respectively. The performance of the EfficientNet-B4 is not better than that of VGG-16 in terms of micro-averaged AUC except for other metrics. For the models to recognize the benign tumor subtypes, the EfficientNet-B4 ranked the best performance, but had no significantly statistical difference with other two models with respect to micro-averaged AUC. CONCLUSIONS The classification results were relatively satisfactory, which showed the potential for clinical application when analyzing the renal tumor macroscopic cross-section images. Automatically distinguishing the malignant tumor from benign tumor and identifying the subtypes pathology of renal tumor could make the patient-management process more efficient.

Front Oncol 2022; 12:945166. [PMID: 36033492 PMCID: PMC9399599 DOI: 10.3389/fonc.2022.945166] [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: 05/16/2022] [Accepted: 07/22/2022] [Indexed: 11/13/2022] Open
Abstract
Background So far, whether positive surgical margin(PSM) has adverse effects on the prognosis of patients is still controversial, so we designed this study to systematically evaluate the effect of PSM on the prognosis of patients with renal cell carcinoma (RCC) after partial nephrectomy (PN). Methods On the basis of three electronic databases (PubMed, Embase and the Cochrane Library) up to May 2022, all case-control studies (CCSs) comparing the effects of PSM and negative surgical margin (NSM) after PN on the oncological results of RCC patients were included. Two evaluators independently conducted a systematic literature search and extracted the data we needed. The methodological quality of all studies was evaluated by the modified Newcastle-Ottawa scale. The odds ratio (OR) was used to describe the results for dichotomous variables, and the meta-analysis was conducted using Cochrane Review Manager 5.2 and Stata 14.2. Results A total of 39 studies involving 21461 patients were included in our meta-analysis. The pooled results showed that the rates of tumor recurrence (OR 3.93, 95% CI 2.95-5.24; p < 0.00001) and metastasis (OR 4.63, 95% CI 3.11-6.88; p < 0.00001) in the PSM group were significantly higher than those in the NSM group. However, there were no significant differences in the rates of all-cause death (OR 1.35, 95% CI 0.92-1.99; p = 0.13) or cancer-specific death (OR 0.99, 95% CI 0.51-1.94; p = 0.99) between the two groups. In addition, subgroup analyses were carried out according to different average follow-ups, which revealed similar results. Conclusion Insignificant differences in survival between the PSM and NSM groups were observed, although significant differences in recurrence and metastasis in the PSM group were reported. Our study supported that close monitoring might be another effective choice for patients with PSM after PN. Considering the possible limitations, we recommended cautious interpretation of our results.

Abstract
A clear margin is an important prognostic factor for most solid tumours treated by surgery. Intraoperative fluorescence imaging using exogenous tumour-specific
fluorescent agents has shown particular benefit in improving complete resection of tumour tissue. However, signal processing for fluorescence imaging is complex, and fluorescence signal intensity does not always perfectly correlate with tumour location. Raman spectroscopy has the capacity to accurately differentiate between malignant and healthy tissue based on their molecular composition. In Raman spectroscopy, specificity is uniquely high, but signal intensity is weak and Raman measurements are mainly performed in a point-wise manner on microscopic tissue volumes, making whole-field assessment temporally unfeasible. In this review, we describe the state-of-the-art of both optical techniques, paying special attention to the combined intraoperative application of fluorescence imaging and Raman spectroscopy in current clinical research. We demonstrate how these techniques are complementary and address the technical challenges that have traditionally led them to be considered mutually exclusive for clinical implementation. Finally, we present a novel strategy that exploits the optimal characteristics of both modalities to facilitate resection with clear surgical margins.

Abstract
Introduction The aim of this article was to compare oncological outcomes after partial nephrectomy between patients with positive (PSM) and negative (NSM) surgical margins. Material and methods In this retrospective study, the data of 733 patients who underwent partial nephrectomy with diagnosis of renal cell carcinoma (RCC) were analyzed. A total of 80 patients from the NSM group were matched to 42 PSM patients. The Kaplan-Meier method was used to estimate freedom from local disease recurrence and metastatic progression and overall survival. Cox proportional hazards models were used to assess the predictors for recurrence/metastasis. Results The mean age was 58.4 ±11.4 years (range: 29 to 82). Median follow-up was 24 months (IQ25-75: 15–36.2). A total of 5 patients from the PSM group (6.2%) developed local recurrence and metastasis was detected in 2 (2.5%) of them while no metastasis or recurrence was observed in the NSM group. In the multivariate analysis, positive surgical margin was the only independent predictor for recurrence/metastasis (HR[CI] = 0.19[0.04–0.75], p = 0.019). Recurrence-free survival was higher in the NSM group (100% for the NSM group vs 88.1%, p = 0.002) and recurrence/metastasis-free survival was also higher in the NSM group (100% for the NSM group vs 85.7%, p = 0.001), but there were no differences in overall survival between the two groups (96.3% for the NSM group vs 97.6% for the PSM group, p = 0.68). Conclusions Although tumor recurrence was more prevalent in positive surgical margin patients who underwent partial nephrectomy, there were no differences in overall survival between the two groups. Therefore, active surveillance against further surgery would be a proper option after finding the tumor-involved margins.

Abstract
OBJECTIVE To evaluate the accuracy of radiological staging, especially renal venous and perirenal fat invasion, in renal cell carcinoma (RCC). MATERIAL AND METHODS Data of 4823 renal tumour patients from Renal Tumor Database of Association of Uro-oncology in Turkey were evaluated. Of 4823 patients, 3309 RCC patients had complete radiological, and histopathological data were included to this study. The Pearson chi-squared test (χ2 ) was used to compare radiological and histopathological stages. RESULTS The mean (SD) age of 3309 patients was 58 (12.3). Preoperative radiological imaging was performed using computed tomography (CT) (n = 2510, 75.8%) or magnetic resonance imaging (MRI) (n = 799, 24.2%). There was a substantial concordance between radiological and pathological staging (к = 0.52, P < .001). Sensitivities of radiological staging in stages I, II, III and IV were 90.7%, 67.3%, 27.7% and 64.2%, respectively. The sensitivity in stage III was lower than the other stages. Subanalysis of stage IIIa cases revealed that, for perirenal fat invasion and renal vein invasion, sensitivity values were 15.4% and 11.3%, respectively. CONCLUSIONS There was a substantial concordance between radiological (CT and/or MRI) and pathological T staging in RCC. However, this is not true for T3 cases. Sensitivity of preoperative radiological imaging in patients with pT3a tumours is insufficient and lower than the other stages. Consequently, preoperative imaging in patients with T3 RCC has to be improved, in order to better inform the patients regarding prognosis of their disease.

A Systematic Review and Meta-analysis. Urology 2021; 156:e30-e39. [PMID: 34186133 DOI: 10.1016/j.urology.2021.04.058] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2021] [Revised: 04/11/2021] [Accepted: 04/14/2021] [Indexed: 01/11/2023]
Abstract
We systematically evaluated the impact of positive surgical margins (PSM) on oncological outcomes after partial nephrectomy for renal cell carcinoma. Forty-two studies comprising 101,153 subjects were included and five distinct meta-analyses were performed. PSM was associated with increased risk of local recurrence (hazard ratio (HR) 6.11-high certainty), metastasis (HR 3.29-moderate certainty), overall relapse (HR 2.25-high certainty), overall mortality (HR 1.30-moderate certainty), and may be associated with increased cancer-specific mortality (HR 1.91-low certainty). Patients with PSM should be counseled for the possibility of additional surgery, novel adjuvant therapies, and more rigorous surveillance.

Abstract
BACKGROUND Few prognostic factors have been proposed for patients with locally advanced renal cell carcinoma (RCC). This study aimed to investigate the possible predictive factors for disease-free survival (DFS) after curative surgery for RCC stage T3 or higher. METHODS Patients with locally advanced RCC who underwent cure-intended partial or radical nephrectomy, with or without tumor thrombectomy, at our institution from April 1, 2005 to October 31, 2013 were retrospectively reviewed. Those undergoing cytoreductive nephrectomy were excluded. Preoperative data, including surgical and pathologic characteristics, were assessed for correlation with DFS. Chi-square tests, univariate and multivariate Cox regression analysis, and Kaplan-Meier survival curve analyses were performed to determine potential predictive factors. A p value less than 0.05 was considered statistically significant. RESULTS A total of 159 patients were included for analysis. The mean duration of follow-up was 37.9 months, and 119 (74.8%) patients remained disease-free during follow-up. Disease recurrence was found in 40 (25.2%) patients, and pathologic T stage, capsule penetration, Fuhrman grade, thrombocytosis, renal vein thrombosis, and elevated serum alkaline phosphatase, platelet/lymphocyte ratio, and γ-glutamyl transpeptidase levels were significantly associated with disease recurrence on univariate analysis. On multivariate analysis, Fuhrman grade 3 or 4 (HR = 5.70, p = 0.0003, 95% CI = 2.23-14.56) showed significant associations with DFS. CONCLUSION In patients with locally advanced RCC, Fuhrman grade was associated with worse DFS after curative surgery. Urologists should closely monitor patients with high Fuhrman grades.

Abstract
Objectives: To evaluate the outcomes of robot-assisted partial nephrectomy (RAPN) in cystic renal tumors. Materials and Methods: We retrospectively analyzed patients who underwent RAPN for either cystic (n = 46) or solid (n = 271) renal tumors at Fujita Health University between 2010 and 2019. Cystic renal tumors were diagnosed using cross-sectional imaging. Perioperative, oncologic, and functional outcomes were assessed. Results: The median follow-up periods were 38, 41, and 37 months in the total, cystic, and solid groups, respectively. Most patient characteristics were similar among both groups, while the median age of the cystic group was significantly lower than that of the solid group (p = 0.02). Most perioperative variables and complications were comparable between the two groups. There was no significant difference between the groups in perioperative renal function. The estimated glomerular filtration rate preservation rates were 93.1% and 89.2% in the cystic and solid groups, respectively (p = 0.17). The cystic group showed a higher benign histology rate (19.6% vs 7%) and lower Fuhrman grade than the solid group (24.3% vs 15.1% in grade 1, and 73% vs 81.3% in grade 2), although there was no statistically significant difference between the two groups. In the solid group, 10 patients (3.7%) experienced recurrence, and 2 patients (0.7%) died of renal-cell carcinoma, while none of the patients with cystic tumors experienced recurrence. There was no statistically significant difference between the cystic and solid tumors with respect to 5-year recurrence-free survival (p = 0.18), cancer-specific survival (p = 0.55), and overall survival (p = 0.35). Conclusions: RAPN for cystic renal tumors appears to be safe and feasible with perioperative, long-term functional and oncologic outcomes comparable with those in solid tumors. RAPN can be a safe and effective surgical option for cystic renal tumors.

Abstract
Background The impact of positive surgical margins (PSMs) after partial nephrectomy (PN) is controversial. Objective To evaluate the risk factors for a PSM and its impact on overall survival. Design, setting, and participants This is a retrospective study of 388 patients were submitted to PN between November 2005 and December 2016 in a single centre. Two groups were created: PSM and negative surgical margin (NSM) after PN. A p value of <0.05 was considered significant. Outcome measurements and statistical analysis Relationships with outcome were assessed using univariable and multivariable tests and log-rank analysis. Results and limitations The PSM rate was 3.8% (N = 16). The mean age at the time of surgery (PSM group: 64.1 ± 11.3 vs NSM group: 61.8 ± 12.8 yr, p = 0.5) and the mean radiological tumour size (4.0 ± 1.5 vs 3.4 ± 1.8 cm, p = 0.2) were similar. Lesion location (p = 0.3), surgical approach (p = 0.4), warm ischaemia time (p = 0.9), and surgery time (p = 0.06) had no association with PSM. However, higher surgeon experience was associated with a lower PSM incidence (2.6% if ≥30 PNs vs 9.6% if <30 PNs; p = 0.02). Higher operative blood loss (p = 0.02), higher-risk tumours (p = 0.03), and larger pathological size (p = 0.05) were associated with an increase in PSM. In the PSM group, recurrence rate (18.7% vs 4.2%, p = 0.007) and secondary total nephrectomy rate (25% vs 4.4%, p < 0.001) were higher. However, overall survival was similar. Multivariate analysis revealed that high-risk tumour (p = 0.05) and low experience (p = 0.03) could predict a PSM. Limitations include retrospective design and reduced follow-up time. Conclusions PSMs were mainly associated with high-risk pathological tumour (p = 0.05) and low-volume surgeon experience. Recurrence rate and need for total nephrectomy were higher in that group, but no impact on survival was noticed. Patient summary The impact of positive surgical margins (PSMs) after partial nephrectomy is a matter of debate. In this study, we found that PSMs were mainly associated with aggressive disease and low surgeon experience.

Abstract
PURPOSE To evaluate the prognostic factors affecting the surgical margin and recurrence in patients who underwent partial nephrectomy (PN) for renal masses. MATERIALS AND METHODS Data of 125 patients who underwent open or laparoscopic PN because of renal mass between January 2006 and January 2019 were analysed retrospectively. Demographic data, habits, additional diseases, clinical and laboratory findings, operational data, the morphology of the tumour in computerised tomography or magnetic-resonance imaging and follow-up data were scanned and acquired via our hospital's system and archive. RESULTS Average age was 54.4, male-female ratio was 1.55 and average tumour size was 3.31 cm. One hundred and four patients had malignant pathology and 21 were benign. Positive surgical margin (PSM) rate was 5.6% and recurrence rate was 3.2%. Average follow-up was 47.4 months. Pathological size of the tumour was larger (P = .006), warm-ischemia period was lower (P = .003) and PADUA score was higher (P = .015) in open technique. Tumour size and tumour stage were statistically higher in patients with recurrence (P = .009, P < .001, respectively). There was a significantly higher PSM ratio in mandatory indication group than elective indication group (P = .025). No statistically significant difference was observed between surgical margin positivity and tumour size, Fuhrman grades, PADUA scores, RENAL scores and C-index. (P > .05). CONCLUSION Surgical margin positivity after PN is not significantly associated with tumour characteristics and anatomical scoring systems. Surgical indication for PN has a direct influence on PSM rates. Tumour size and stage after PN are valuable parameters in evaluating the recurrence risk.

Abstract
BACKGROUND The impact of positive surgical margins (PSM) on outcomes in partial nephrectomy (PN) is controversial. We investigated impact of PSM for patients undergoing PN on overall survival (OS) in different stages of renal cell carcinoma (RCC). METHODS Retrospective analysis of patients from the US National Cancer Database who underwent PN for cT1a-cT2b N0M0 RCC between 2004-13. Patients were stratified by pathological stage (pT1a, pT1b, pT2a, pT2b, and pT3a [upstaged]) and analyzed by margin status. Cox Regression multivariable analysis (MVA) was performed to investigate associations of PSM and covariates on all-cause mortality (ACM). Kaplan-Meier analysis (KMA) of OS was performed for PSM versus negative margin (NSM) by pathological stage. Sub-analysis of Charlson Comorbidity Index 0 (CCI=0) subgroup was conducted to reduce bias from comorbidities. RESULTS We analyzed 42,113 PN (pT1a: 33,341 [79.2%]; pT1a, pT1b: 6689 [15.9%]; pT2a: 757 [1.8%]; pT2b: 165 [0.4%]; and pT3a: upstaged 1161 [2.8%]). PSM occurred in 6.7% (2823) (pT1a: 6.5%, pT1b: 6.3%, pT2a: 5.9%, pT2b: 6.1%, pT3a: 14.1%, P<0.001). On MVA, PSM was associated with 31% increase in ACM (HR 1.31, P<0.001), which persisted in CCI=0 sub-analysis (HR: 1.25, P<0.001). KMA revealed negative impact of PSM vs. NSM on 5-year OS: pT1 (87.3% vs. 90.9%, P<0.001), pT2 (86.7% vs. 82.5%, P=0.48), and upstaged pT3a (69% vs. 84.2%, P<0.001). CONCLUSIONS PSM after PN was independently associated with across-the-board decrement in OS, which worsened in pT3a disease and persisted in sub-analysis of patients with CCI=0. PSM should prompt more aggressive surveillance or definitive resection strategies.

Abstract
Background Previous reports on positive surgical margin (PSM) after robot-assisted partial nephrectomy (RAPN) have reached inconsistent conclusions as to the impact of a PSM on oncologic outcomes. We sought to determine the effect of PSM on long-term cancer recurrence and survival outcomes. Methods We queried our renal oncology database for patients having undergone RAPN and compared recurrence-free survival (RFS) and overall survival (OS) between patients with PSM and negative surgical margin (NSM). Kaplan-Meier analysis was also performed for RFS and OS for PSM versus NSM. Results Of the 432 patients who underwent RAPN we identified 29 (6.7%) patients with PSM and 403 (93.3%) patients with NSM. Median follow-up for the overall cohort was 45.1 months. Three of the 29 patients with PSM and fourteen of the 403 patients with NSM had disease recurrence (P=0.09). RFS at 24, 48, and 72 months was 95.8%, 90%, and 85.5% for patients with NSM and 96.6%, 86.6%, and 80.4% for patients with PSM, respectively (log-rank P value =0.382). OS at 24, 48, and 72 months was 98%, 93.1%, and 89.7% for patients with NSM and 96.3%, 91.2%, and 85.2% for patients with PSM, respectively (log-rank P value =0.584). Conclusions While PSM are relatively uncommon, their presence still serves as a potential risk factor for worse oncologic outcomes. In instances of PSM, immediate secondary intervention is most likely unnecessary and more attentive long-term clinical follow-up, especially in patients with high-risk features, may be more advisable.

Abstract
SIGNIFICANCE A key risk faced by oncological surgeons continues to be complete removal of tumor. Currently, there is no intraoperative imaging device to detect kidney tumors during excision. AIM We are evaluating molecular chemical imaging (MCI) as a technology for real-time tumor detection and margin assessment during tumor removal surgeries. APPROACH In exploratory studies, we evaluate visible near infrared (Vis-NIR) MCI for differentiating tumor from adjacent tissue in ex vivo human kidney specimens, and in anaesthetized mice with breast or lung tumor xenografts. Differentiation of tumor from nontumor tissues is made possible with diffuse reflectance spectroscopic signatures and hyperspectral imaging technology. Tumor detection is achieved by score image generation to localize the tumor, followed by application of computer vision algorithms to define tumor border. RESULTS Performance of a partial least squares discriminant analysis (PLS-DA) model for kidney tumor in a 22-patient study is 0.96 for area under the receiver operating characteristic curve. A PLS-DA model for in vivo breast and lung tumor xenografts performs with 100% sensitivity, 83% specificity, and 89% accuracy. CONCLUSION Detection of cancer in surgically resected human kidney tissues is demonstrated ex vivo with Vis-NIR MCI, and in vivo on mice with breast or lung xenografts.

Predicting positive surgical margins in partial nephrectomy: A prospective multicentre observational study (the RECORd 2 project). Eur J Surg Oncol 2020; 46:1353-1359. [PMID: 32007380 DOI: 10.1016/j.ejso.2020.01.022] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Accepted: 01/15/2020] [Indexed: 01/17/2023] Open
Abstract
PURPOSE to evaluate clinical predictors of positive surgical margins (PSMs) in a large multicenter prospective observational study and to develop a clinic nomogram to predict the likelihood of PSMs after partial nephrectomy (PN). MATERIALS AND METHODS We prospectively evaluated 4308 patients who had surgical treatment for renal tumors between January 2013 and December 2016 at 26 urological Italian Centers (RECORd 2 project). Two multivariable logistic models were evaluated to predict the likelihood of PSMs. Center caseload was dichotomized using a visual assessment adjusted for several predictors of PSMs. A nomogram predicting PSMs was developed. RESULTS Overall, 2076 patients treated with PN were evaluated. pT1a, pT1b, pT2 and pT3a were recorded in 68.7%, 22.6%, 2.1% and 6.6% of the patients, respectively. PSMs were recorded in 342 (16.5%) patients. From a null multivariable model against number of PN/year, 60 PN/year were identified as the best cut-off to define a high-volume centre. At multivariable analysis, clinical stage (cT1a vs. cT2 [OR 1.94]; p = 0.03), volume centre (≤60 PN/year) (OR 2.22; p < 0.0001), imperative vs elective indication (OR 2.10; p = 0.04), surgical technique (laparoscopic vs. open [OR 1.62; p = 0.002), lymphovascular invasion (OR 2.27; p = 0.01) and upstaging to pT3a (OR 2.81; p < 0.0001) were independent predictors of PSMs. The final nomogram included age, ASA score, Charlson score, clinical tumor stage, surgical indication, surgical approach, surgical technique, PADUA score, clamp procedure and volume centre. CONCLUSIONS PSMs after PN were significantly more likely in patients with lower clinical stage, higher PADUA score, in individuals referred to laparoscopic PN and in those treated at lower volume centers. We used these data to develop a nomogram to predict such risk.

The Correlation of Clinicopathological Features With the Status of Surgical Margins in Renal Cell Cancer Patients Following Nephron-Sparing Surgery: A Systematic Review and Meta-Analysis. Front Oncol 2019; 9:648.

Abstract
Objectives: The aim of this study was to evaluate the correlation of various clinicopathological variables with positive surgical margins (PSMs) in renal cell cancer (RCC) patients after nephron-sparing surgery (NSS). Methods: A systematic search of PubMed, EMBASE, Web of Science, and China National Knowledge Infrastructure (CNKI) was performed to identify studies that compared PSMs with negative surgical margins (NSMs) and were published up to December 2018. Outcomes of interest included perioperative and postoperative variables, and the data were pooled by odds ratios (ORs)/standard mean differences (SMD) with 95% confidence intervals (CIs) to evaluate the strength of such associations. STATA 12.0 software was used for all statistical analyses. Results: Based on the inclusion and exclusion criteria, 13 studies including 47,499 patients with RCC were analyzed. The results showed that higher Furhman grade (pooled OR = 1.25; 95% CI: 1.14-1.37; P < 0.001), higher pathological stage (pooled OR = 2.67; 95% CI: 2.05-3.50; P < 0.001), non-clear cell RCC (non-ccRCC) histology (pooled OR = 0.78; 95% CI: 0.72-0.84; P < 0.001), and non-white race (pooled OR = 0.90; 95% CI: 0.82-0.99; P = 0.026) were significantly associated with high risk of PSMs. However, age (pooled SMD = 0.09; 95% CI: -0.01-0.20; P = 0.078), gender (female vs. male) (pooled OR = 1.04; 95% CI: 0.96-1.12; P = 0.377), tumor laterality (left vs. right) (pooled OR = 1.09; 95% CI: 0.84-1.42; P = 0.501), tumor focality (unifocal vs. multifocal) (pooled OR = 0.67; 95% CI: 0.23-1.90; P = 0.445), tumor size (pooled SMD = 0.03; 95% CI: -0.10-0.15; P = 0.685), and surgical approach (open vs. non-open) (pooled OR = 0.94; 95% CI: 0.62-1.42; P = 0.763) had no relationship with PSMs. Sensitivity analysis showed that all models were stable, and no publication bias was observed in our study. Conclusions: The present findings demonstrate that the presence of PSMs was associated with higher Furhman grade and higher pathological stage. Additionally, non-white patients with non-ccRCC histology had a high risk of PSMs after NSS. Further multicenter and long-term follow-up studies are required to verify these findings.

Abstract
Background Partial nephrectomy has emerged as a standard treatment for small renal masses offering oncologic control equivalent to radical nephrectomy, with preservation of renal function and evidence for equivalent survival. In this study, we evaluated RENAL nephrometry score (RNS) in predicting perioperative outcomes in patients with partial nephrectomy. Materials and Methods This was a prospective observational study conducted from February 2016 to August 2017 which included patients who underwent partial nephrectomy. The patients were divided into three groups depending on the complexity scores (low, moderate, and high). Tumors were assigned RNS and tumor-node-metastasis staging of the clinically malignant tumors was done. Blood loss, warm ischemia time (WIT), and surgical complications were assessed. Results A total of 20 patients underwent open partial nephrectomy during the study. There were 4 (20%) low, 11 (55%) moderate, and 5 (25%) high-complexity lesions. Blood loss was significantly different in three groups. All the cases in high-complexity group were performed with clamping the renal vessels with a mean WIT of 29 min. The overall complication rates were significantly different between the groups (P = 0.007); however, majority of the complications were low grade (Grades I and II) and were managed conservatively. Conclusion In the present study, RNS was correlated with predicting surgical access route, need for clamping during partial nephrectomy, blood loss, decrease in glomerular filtration rate of operated kidneys, postoperative complications, and tumor grade.

Low Rate of Cancer Events After Partial Nephrectomy for Renal Cell Carcinoma: Clinicopathologic Analysis of 1994 Cases with Emphasis on Definition of "Recurrence". Clin Genitourin Cancer 2019; 17:209-215.e1. [PMID: 31000486 DOI: 10.1016/j.clgc.2019.03.004] [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: 01/08/2019] [Revised: 03/04/2019] [Accepted: 03/06/2019] [Indexed: 11/28/2022]
Abstract
BACKGROUND Systematic pathology reviews in patients who experienced a clinical "recurrence" after partial nephrectomy for renal cell carcinoma (RCC) are anecdotal; therefore, definitions of "recurrence" varies considerably. We aimed to better define local recurrence by re-evaluation of surgical specimens of patients who experienced "recurrences" after partial nephrectomy at our institution. MATERIALS AND METHODS Retrospective analysis of our institutional partial nephrectomy data set was performed. Patients who were clinically diagnosed with a local recurrence during the oncological follow-up after primary intervention for RCC were considered (January 2007 to December 2017, institutional review board number 5065, 15-1593). Re-evaluation of specimens coming from either primary treatment or management of the diagnosed recurrent disease was performed by 2 dedicated urologic pathologists. According to the findings of the pathology review, patients were assigned to 3 groups of disease event: (1) local recurrence of RCC; (2) new occurrence of RCC; and (3) micrometastatic RCC. Patient demographic characteristics, tumor pathological characteristics, oncological outcomes, disease treatment, and follow-up were reported for each patient. Cancer-specific survival was compared using the Kaplan-Meier method. RESULTS Of 1994 cases recorded in the institutional database, data on 30 patients who were clinically diagnosed with a local recurrence were extracted. After pathology review, 9 patients were found who truly developed a local recurrence (group 1). Positive surgical margin status was poorly related to the likelihood of a true local recurrence as defined herein. Twelve patients were assessed with a new occurrence of RCC (group 2). Nine were diagnosed with micrometastatic RCC (group 3). With comparable follow-up lengths among the groups (39 [interquartile range (IQR), 32-45] versus 51.5 [IQR, 35-90.5] versus 42 [IQR, 13-65], group 1 versus 2 versus 3, respectively; P = .4), patients classified in group 1 and 3 had comparable cancer-specific survival (P = .5). Conversely, patients in group 2 were less likely to die of disease compared with group 1 and 3 patients (P = .02). CONCLUSION Careful pathologic classification of RCC disease events after partial nephrectomy has important prognostic implications and allows more precise study of the clinical significance of margin status.

Abstract
PURPOSE While surgical approach has recently been associated with positive surgical margin (PSM) after partial nephrectomy (PN) for small (<4 cm) renal masses, its impact on margin status for large (>4 cm) masses is unclear. We sought to evaluate the relationship between margin and surgical approach in patients undergoing PN for large renal masses. MATERIALS AND METHODS Using the National Cancer Database (NCDB), we identified patients undergoing PN for pathological T1b and T2a renal-cell carcinoma diagnosed from 2010 to 2013. Conversions to open surgery were also included in our analysis. The primary outcome was surgical margin status. Multivariable regression modeling was performed to identify factors associated with PSM. A propensity score matching analysis was then performed to evaluate the impact of margin status on overall survival (OS). RESULTS Of the 7495 patients undergoing PN for pT1b and pT2a renal masses over the study period, 504 (6.7%) had PSM. On multivariable analysis, surgical approach (laparoscopic or robot assisted vs open) was not significantly associated with surgical margin (p = 0.12 and p = 0.44, respectively). Tumor stage (T2a vs T1b) also showed no significant association (p = 0.18). A subsequent multivariable analysis using clinical staging showed that surgical approach (p = 0.28 and p = 0.54, respectively), tumor stage (p = 0.78), and conversion-to-open surgery (p = 0.98) had no significant association with PSM. Propensity score matched analysis showed that PSM was not significantly associated with OS (hazard ratio 0.95 [95% confidence interval 0.47-1.92] p = 0.88). CONCLUSION In a contemporary nation-wide cohort, surgical approach was not associated with an increased risk of PSM for large, noninvasive renal masses. Furthermore, increased size from T1b to T2a was not associated with an increased risk of PSM. These data suggest that surgical approach should be selected by surgeon comfort level with an individual tumor, rather than the size of the tumor itself.

Abstract
OBJECTIVE To identify preoperative factors that predict positive surgical margins in partial nephrectomy. MATERIAL AND METHODS Using our institutional partial nephrectomy database, we investigated the patients who underwent partial nephrectomy for malignant tumors between January 2011 and December 2015. Patient, tumor, surgeon characteristics were compared by surgical margin status. Multivariable logistic regression was used to identify independent predictors of positive surgical margins. RESULTS A total of 1025 cases were available for analysis, of which 65 and 960 had positive and negative surgical margins, respectively. On univariate analysis, positive margins were associated with older age (64.3 vs. 59.6, p<0.01), history of prior ipsilateral kidney surgery (13.8% vs. 5.6%, p<0.01), lower preoperative eGFR (74.7 mL/min/1.73 m2 vs. 81.2 mL/min/1.73 m2, p=0.01), high tumor complexity (31.8% vs. 19.0%, p=0.03), hilar tumor location (23.1% vs. 12.5%, p=0.01), and lower surgeon volume (p<0.01). Robotic versus open approach was not associated with the risk of positive margins (p=0.79). On multivariable analysis, lower preoperative eGFR, p=0.01), hilar tumor location (p=0.01), and lower surgeon volume (p<0.01) were found to be independent predictors of positive margins. CONCLUSION In our large institutional series of partial nephrectomy cases, patient, tumor, and surgeon factors influence the risk of positive margins. Of these, surgeon volume is the single most important predictor of surgical margin status, indicating that optimal oncological outcomes are best achieved by high-volume surgeons.

Abstract
OBJECTIVES To compare perioperative outcomes of robotic-assisted partial nephrectomy (RaPN) with open partial nephrectomy (OPN). METHODS Systematically search through PubMed, Embase, ClinicalKey, Cochrane Library, ProQuest, ScienceDirect, Web of Science, and ClinicalTrials.gov for eligible studies was performed to April 11, 2018. A meta-analysis was conducted for studies comparing RaPN and OPN. Confounding variables were assessed by meta-regression or subgroup analysis. RESULTS This study included 34 studies with 60 808 patients. Meta-analysis revealed less blood loss, less transfusion, longer operative time, less postoperative complications, lower readmission rate, shorter length of stay, and less estimated glomerular filtration rate (eGFR) decline in RaPN groups. The superiority of RaPN in blood loss was attenuated with highly complex renal masses. The superiority of RaPN in intraoperative complications was strengthened with renal hilar control. The advantage of RaPN in surgical margin was increased in patient with body mass index (BMI) < 28. CONCLUSIONS Compared with OPN, RaPN provided lower morbidities and better renal function preservation.

Abstract
Partial nephrectomy (PN) is the recommended procedure over radical nephrectomy (RN) for patients with renal masses less than 4 cm in diameter (Stage T1a). Patients with less than 4 cm renal masses can also be treated with PN, but have a higher risk for positive surgical margins (PSM). PSM, when present, are indicative of poor clinical outcomes. The current gold-standard histopathology method is not well-suited for the identification of PSM intraoperatively due to processing time and destructive nature. Here, video-rate structured illumination microscopy (VR-SIM) was investigated as a potential tool for PSM detection during PN. A clinical image atlas assembled from ex vivo renal biopsies provided diagnostically useful images of benign and malignant kidney, similar to permanent histopathology. VR-SIM was then used to image entire parenchymal margins of tumor resection covering up to >1800× more margin surface area than standard histology. Aided by the image atlas, the study pathologist correctly classified all parenchymal margins as negative for PSM with VR-SIM, compared to standard postoperative pathology. The ability to evaluate large surgical margins in a short time frame with VR-SIM may allow it to be used intraoperatively as a "safety net" for PSM detection, allowing more patients to undergo PN over RN.

Abstract
Objectives: To evaluate the prognosis of non-metastatic T3a renal cell carcinoma (RCC) with partial nephrectomy (PN). Patients and Methods: We retrospectively evaluated 125 patients with non-metastatic T3a RCC. Patients undergoing PN and radical nephrectomy (RN) were strictly matched by clinic-pathologic characteristics. Log-rank test and Cox regression model were used for univariate and multivariate analysis. Results: 18 pair patients were matched and the median follow-up was 35.5 (10-86) months. PN patients had a higher postoperative eGFR than RN patients (P=0.034). Cancer-specific survival (CSS) and recurrence-free survival (RFS) did not differ between two groups (P=0.305 and P=0.524). On multivariate analysis, CSS decreased with positive surgical margin and anemia (both P <0.01) and RFS decreased with Furhman grade, positive surgical margin, and anemia (all P<0.01). Conclusions: For patients with non-metastatic pT3a RCC, PN may be a possible option for similar oncology outcomes and better renal function.

Abstract
Background Positive surgical margins (PSM) are recognized as an adverse prognostic sign and are often associated with higher rates of local and systemic disease recurrence. The data regarding the oncological outcome for PSM following radical nephrectomy (RN) is limited. We examined the predictive factors for PSM and its influence on survival and site of recurrence in patients treated with RN for renal cell carcinoma (RCC). Methods Clinical, pathologic and follow-up data on 714 patients undergoing RN for kidney cancer were analyzed. Secondary analysis included 44 patients with metastatic RCC upon diagnosis who underwent cytoreductive nephrectomy (CRN). Univariate and multivariable logistic regression models were fit to determine clinicopathologic features associated with PSM. A Cox proportional-hazards regression model was used to test the independent effects of clinical and pathologic variables on survival. Results PSM was documented in 17 cases (2.4%). PSM were associated with tumour size, advanced pathologic stage (pT3 vs. ≤ pT2) and presence of necrosis. On multivariate analysis, cancer-specific survival (CSS) was associated with tumour stage, size, presence of necrosis and PSM. PSM was also associated with local recurrence but not distant metastasis or overall survival (OS). CSS and OS were comparable between the PSM and metastatic RCC groups, but significantly lower than the negative margin group. Conclusions The prevalence of PSM following RN is rare. Pathological data, including advanced stage (> pT2), tumour necrosis and tumour size, are associated with the presence of PSM. PSM is associated with tumour recurrence and CSS. Patients with PSM are a potential group for adjuvant therapy or for more careful and thorough follow-up following surgery.

Abstract
INTRODUCTION We sought to determine the incidence, risk factors, and prognosis for patients with positive surgical margin (PSM) during partial nephrectomy (PN) for renal cell carcinoma (RCC). METHODS From the Canadian Kidney Cancer information system (CKCis) database, a historical cohort of PN patients with PSM were identified and compared to negative surgical margin (NSM). Risk factors for PSM were examined through multivariable logistic regression. Kaplan-Meier curves were used to compare progression-free survival. RESULTS Of 1103 patients, 972 (88.1%), 71 (6.4%), and 60 (5.4%) had NSM, PSM, and unknown status, respectively. Median patient age and tumour size were 61 years and 3.0 cm for both groups. From multivariable analysis, pathological stage ≥T3 (odds ratio [OR] 2.51; 95% confidence interval [CI] 1.13-5.60) and Fuhrman grade 4 (OR 5.35; 95% CI 1.11-25.72) were associated with PSM, whereas age, operative technique, and tumour size were not. Forty-nine (5.0%) patients from the NSM cohort and seven (9.9%) from the PSM cohort had a local/systemic progression of disease (adjusted hazard ratio [HR] 1.4; 95% CI 0.6-3.6). There were three (0.3%) cancer-related deaths in the NSM group and none in the PSM group. After median followup of 19 (interquartile range [IQR] 5-42) and 15 (IQR 7-30) months, 855 (91.4%) and 61 (89.7%) patients were alive in the NSM and PSM groups, respectively. CONCLUSIONS PSM occurred in 6.4% of PNs performed for RCC in this pan-Canadian cohort. Higher stage and grade are associated with a higher risk of positive margin. The small association between a PSM and progression suggests that complete nephrectomy is not necessary in patients with a PSM. The main study limitations are lack of nephrometry score and possible reporting bias.

Abstract
OBJECTIVES To analyze long-term outcomes of robot-assisted partial nephrectomy for treatment of complex cystic renal tumors. METHODS We retrospectively analyzed the data of patients who underwent robot-assisted partial nephrectomy for cystic (n = 32) and solid (n = 263) renal masses at Severance Hospital, Seoul, Korea. The primary outcome was assessment of perioperative safety for cystic tumor. Secondary outcomes were evaluation of long-term oncological and functional results. RESULTS Patients' clinical and demographic characteristics were similar among both groups. The median follow up of cystic and solid masses were 58 and 46 months, respectively. Cystic masses were more likely to have low Fuhrman grade 1 and 2 (P = 0.03), and shorter operative time (P = 0.04) compared with solid masses. There was no statistically significant difference regarding warm ischemia time, estimated blood loss, trifecta achievement, length of hospital stay, complication rates and renal function preservation (P > 0.05) between groups. In the solid group, 12 patients (4.1%) recurred, and six patients (2%) died from metastatic renal cell carcinoma, whereas the patients in the cystic group did not have any local or distance recurrence, and the survival rates were 100%. The 5-year cancer-free survival (P = 0.77), cancer-specific survival (P = 0.65) and overall survival (P = 0.83) rates were similar between the groups. CONCLUSION Robot-assisted partial nephrectomy appears to be safe and feasible treatment for complex cystic renal masses. It confers excellent long-term oncological outcomes. Robot-assisted partial nephrectomy should be the treatment of choice for complex cysts whenever feasible.

Abstract
Background To compare the surgical margin status after open partial nephrectomy (OPN) and robotic partial nephrectomy (RPN) performed in patients with T1a renal cell carcinoma (RCC). Methods This was a propensity score-matched study including 702 patients with cT1a RCC treated with partial nephrectomy (PN) between May 2003 and July 2015. Perioperative parameters, including surgical margin width after PN, were compared between two surgical methods. After determining propensity score for tumor size and location, the width of peritumoral surgical margin was investigated. Multivariate logistic analysis to predict peritumoral surgical margin less than 1mm was analyzed. Results The mean width of peritumoral surgical margin was 2.61 ± 2.15 mm in OPN group (n = 385), significantly wider than the 2.29 ± 2.00 mm of RPN group (n = 317) (p = 0.042). The multivariate analysis showed surgical methods was significant factors to narrow surgical margin less than 1mm (p = 0.031). After propensity score matching, the surgical margin width was significantly longer in OPN (2.67 ± 2.14 mm) group than RPN (2.25 ± 2.03 mm) group (p = 0.016). A positive resection margin occurred in 7 (1.8%) patients in the OPN group and 4 (1.3%) in the RPN group. During the median follow-up of 48.3 months, two patients who underwent OPN had tumor bed recurrence. Conclusions RPN may result in a narrower peritumoral surgical margin than OPN. Further investigation on the potential impact of such a phenomenon should be performed in a larger-scale study.

Abstract
PURPOSE To assess the risk factors of positive surgical margins (PSM) and the influence of margin status on recurrence in pT1 clear cell renal cell carcinoma (RCC) following partial nephrectomy (PN). MATERIALS AND METHODS Patients (1,831) with pathologically confirmed stage T1 clear cell RCC were retrospectively analyzed following PN at eight institutions in Korea between 1999 and 2011. Demographics, operative data, pathological margin status, and site of recurrence were analyzed. RESULTS Resection margins were positive in 31 patients (1.7% of the cohort) on final pathology. None of the clinicopathological parameters were significantly related to the marginal status (all P > 0.05). During a median follow-up of 32.5 months, local recurrences were observed in 0.4% of negative surgical margins. There was no local recurrence in any of the cases with PSM. Distant recurrences developed in 1.7% of negative surgical margins and 3.2% of PSM. There were no significant differences in recurrence-free survival by margin status (P = 0.566). CONCLUSIONS Our multi-institutional data suggest that marginal status does not influence tumor recurrence risk in pT1 clear cell RCC after PN. Careful surveillance seems to be a sufficient strategy in this clinical scenario. J. Surg. Oncol. 2016;114:70-74. © 2016 Wiley Periodicals, Inc.

Transplantation of Restored Kidneys From Unrelated Donors After Resection of Renal Cell Carcinoma: Results From 10 Patients. Transplant Proc 2016; 47:1711-9.

Abstract
PURPOSE To relieve the chronic shortage of donor kidneys, we conducted a prospective kidney transplantation trial using kidneys removed from 10 unrelated patients (51 to 79 years of age) who had undergone nephrectomy for small renal cell carcinoma (1.5 to 3.9 cm) of low-to-moderate complexity based on RENAL (radius, exophytic/endophytic properties, nearness of tumor to the collecting system or sinus in millimeters, anterior/posterior location relative to polar lines) nephrometry (objective description helpful for operative indication and planning). METHODS Donors were selected from among 15 patients who opted to undergo nephrectomy for small renal cell carcinoma. A total of 76 dialysis patients 34 to 85 years of age who agreed to undergo restored kidney transplantation were recruited as transplant candidates. RESULTS In stage 1 (5 cases), high-risk patients were selected without human leukocyte antigen testing, and accelerated acute rejection occurred in 4 of 5 recipients. This trial was subsequently extended with human leukocyte antigen testing, and an additional 5 patients were enrolled in stage 2. Eight recipients, including 4 recipients with a history of renal transplantation, experienced rejection; 1 patient resumed dialysis 35 months after transplantation. The most recent serum creatinine levels ranged from 1.10 to 3.19 mg/dL in the 9 recipients with functioning grafts and from 0.84 to 4.68 mg/dL in the 10 donors. No tumor recurrence was noted at 32 to 58 months after surgery in either the recipients or the donors. CONCLUSIONS Restored kidney transplantation using kidneys with a small renal tumor seems suitable for carefully selected high-risk recipients and, in particular, elderly kidneys can also function well. Avoiding cancer transmission, fair recipient selection, close follow-up, and a well-organized tracking system warrant further study.

Abstract
PURPOSE The clinical significance of a positive surgical margin after partial nephrectomy remains controversial. The association between positive margin and risk of disease recurrence in patients with clinically localized renal neoplasms undergoing partial nephrectomy was evaluated. MATERIALS AND METHODS A retrospective multi-institutional review of 1,240 patients undergoing partial nephrectomy for clinically localized renal cell carcinoma between 2006 and 2013 was performed. Recurrence-free survival was estimated using the Kaplan-Meier method and evaluated as a function of positive surgical margin with the log rank test and Cox models adjusting for tumor size, grade, histology, pathological stage, focality and laterality. The relationship between positive margin and risk of relapse was evaluated independently for pathological high risk (pT2-3a or Fuhrman grades III-IV) and low risk (pT1 and Fuhrman grades I-II) groups. RESULTS A positive surgical margin was encountered in 97 (7.8%) patients. Recurrence developed in 69 (5.6%) patients during a median followup of 33 months, including 37 (10.3%) with high risk disease (eg pT2-pT3a or Fuhrman grade III-IV). A positive margin was associated with an increased risk of relapse on multivariable analysis (HR 2.08, 95% CI 1.09-3.97, p=0.03) but not with site of recurrence. In a stratified analysis based on pathological features, a positive surgical margin was significantly associated with a higher risk of recurrence in cases considered high risk (HR 7.48, 95% CI 2.75-20.34, p <0.001) but not low risk (HR 0.62, 95% CI 0.08-4.75, p=0.647). CONCLUSIONS Positive surgical margins after partial nephrectomy increase the risk of disease recurrence, primarily in patients with adverse pathological features.

Abstract
PURPOSE To analyse the mid-term oncological results and to asses predictive factors for recurrence and survival after nephron-sparing surgery (NSS) for renal cell carcinoma. MATERIALS AND METHODS This is a retrospective study that includes 198 Partial Nephrectomies performed at our institution for malignant renal tumours. Demographic information and pathological characteristics were obtained, and completed statistical analysis was performed to assess predictors for overall survival (OS) and overall recurrence in our sample. RESULTS The presence of positive surgical margins (PSM) in the surgical specimen was reported in 13.6 %. At a median of follow-up of 56.1 months, the non-adjusted cancer-specific mortality, DSS and OS were 100, and 93.4 %, respectively. In the bivariate analysis regarding predictive factors for recurrence, bilaterality and NSS indication (elective or imperative) were statistically significant (p = 0.03 and p = 0.05 respectively). On multivariate analysis only bilaterality was a significant predictor of recurrence (p = 0.03), while high Fuhrman grade was for survival (p = 0.006). CONCLUSION Our data suggest that patients with bilateral tumours have a higher incidence of local recurrence. Regarding overall survival, our data showed more risk of death at 5 years in those patients with high Fuhrman grade. No differences were found among PSM and negative surgical margins patients regarding oncological outcomes.

Abstract
INTRODUCTION We described the clinical and oncological outcomes of patients treated by laparoscopic surgery for non-metastatic pT3 renal cell carcinoma (RCC). METHODS We queried a multi-institutional database for patients diagnosed with non-metastatic pathological T3 RCC from 13 Canadian centres treated laparoscopically (radical or partial nephrectomy) between 2008 and 2014. Clinical and pathological outcomes were evaluated. Progression was defined as the development of recurrence or metastatic disease. Log-rank testing and Kaplan-Meier statistical methods assessed for differences and estimated progression-free survival (PFS). RESULTS In total, 176 patients were identified with a median age of 64 years. The median tumour size was 7.0 cm. Pre-clinical stage was cT1 to cT4 in 39%, 28%, 30% and 3%, respectively. The median blood loss was 150 mL (range: 0-6000) and the median operative time was 124 minutes (range: 60-360). Most lesions were clear cell RCC (80%). After a median follow-up of 17.6 months (range: 0.2-75.0), disease progression occurred in 26% (46/176) of patients, consisting of local recurrence in 7% (3/46), and metastatic disease in 93% (43/46). The 3-year PFS was 67%, with a median PFS of 49 months. Of those who progressed, the median time to progression was 10.3 months. CONCLUSIONS This study is the largest cohort of pT3 RCC patients treated laparoscopically in the literature and suggests that for properly selected patients, laparoscopic management of locally advanced renal masses yields acceptable short-term oncological outcomes.

Robotic unclamped "minimal-margin" partial nephrectomy: ongoing refinement of the anatomic zero-ischemia concept. Eur Urol 2015; 68:705-12. [PMID: 26071789 DOI: 10.1016/j.eururo.2015.04.044] [Citation(s) in RCA: 65] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2015] [Accepted: 04/30/2015] [Indexed: 11/25/2022]
Abstract
BACKGROUND Anatomic partial nephrectomy (PN) techniques aim to decrease or eliminate global renal ischemia. OBJECTIVE To report the technical feasibility of completely unclamped "minimal-margin" robotic PN. We also illustrate the stepwise evolution of anatomic PN surgery with related outcomes data. DESIGN, SETTING, AND PARTICIPANTS This study was a retrospective analysis of 179 contemporary patients undergoing anatomic PN at a tertiary academic institution between October 2009 and February 2013. Consecutive consented patients were grouped into three cohorts: group 1, with superselective clamping and developmental-curve experience (n = 70); group 2, with superselective clamping and mature experience (n = 60); and group 3, which had completely unclamped, minimal-margin PN (n = 49). SURGICAL PROCEDURE Patients in groups 1 and 2 underwent superselective tumor-specific devascularization, whereas patients in group 3 underwent completely unclamped minimal-margin PN adjacent to the tumor edge, a technique that takes advantage of the radially oriented intrarenal architecture and anatomy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Primary outcomes assessed the technical feasibility of robotic, completely unclamped, minimal-margin PN; short-term changes in estimated glomerular filtration rate (eGFR); and development of new-onset chronic kidney disease (CKD) stage >3. Secondary outcome measures included perioperative variables, 30-d complications, and histopathologic outcomes. RESULTS AND LIMITATIONS Demographic data were similar among groups. For similarly sized tumors (p = 0.13), percentage of kidney preserved was greater (p = 0.047) and margin width was narrower (p = 0.0004) in group 3. In addition, group 3 had less blood loss (200, 225, and 150ml; p = 0.04), lower transfusion rates (21%, 23%, and 4%; p = 0.008), and shorter hospital stay (p = 0.006), whereas operative time and 30-d complication rates were similar. At 1-mo postoperatively, median percentage reduction in eGFR was similar (7.6%, 0%, and 3.0%; p = 0.53); however, new-onset CKD stage >3 occurred less frequently in group 3 (23%, 10%, and 2%; p = 0.003). Study limitations included retrospective analysis, small sample size, and short follow-up. CONCLUSIONS We developed an anatomically based technique of robotic, unclamped, minimal-margin PN. This evolution from selective clamped to unclamped PN may further optimize functional outcomes but requires external validation and longer follow-up. PATIENT SUMMARY The technical evolution of partial nephrectomy surgery is aimed at eliminating global renal damage from the cessation of blood flow. An unclamped minimal-margin technique is described and may offer renal functional advantage but requires long-term follow-up and validation at other institutions.
