Influence of tumor thrombus morphology on the surgical complexity in renal cell carcinoma with inferior vena cava tumor thrombus: a single-center, large-sample study from China. World J Urol 2024; 42:454. [PMID: 39073634 PMCID: PMC11286623 DOI: 10.1007/s00345-024-05170-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 07/09/2024] [Indexed: 07/30/2024] Open
Abstract
BACKGROUND The morphology of tumor thrombus varies from person to person and it may affect surgical methods and tumor prognosis. However, studies on the morphology of tumor thrombus are limited. The purpose of our study was to evaluate the impact of tumor thrombus morphology on surgical complexity. METHODS We retrospectively reviewed the clinical data of 229 patients with renal cell carcinoma combined with inferior vena cava (IVC) tumor thrombus who underwent surgical treatment at Peking University Third Hospital between January 2014 and December 2021. The patients were divided into floating morphology (107 patients) and filled morphology (122 patients) tumor thrombi groups. Chi-square and Mann-Whitney U tests were used for categorical and continuous variables, respectively. Postoperative complications were evaluated using the Clavien-Dindo surgical complication classification method. RESULTS Patients with filled morphology tumor thrombus required more surgical techniques than those with floating morphology tumor thrombus, which was reflected in more open surgeries (P < 0.001), more IVC interruptions (P <0.001), lesser use of the delayed occlusion of the proximal inferior vena cava (DOPI) technique (P < 0.001), and a greater need for cut-off of the short hepatic vein (P < 0.001) and liver dissociation (P = 0.001). Filled morphology significantly increased the difficulty of surgery in patients with renal cell carcinoma with tumor thrombus, reflected in longer operation time (P < 0.001), more surgical blood loss (P <0.001), more intra-operative blood transfusion (P < 0.001), and longer postoperative hospital stay (P < 0.001). Filled morphology tumor thrombus also led to more postoperative complications (53% vs. 20%; P < 0.001). CONCLUSION Compared with floating morphology thrombus, filled morphology thrombus significantly increased the difficulty of surgery in patients with renal cell carcinoma with IVC tumor thrombus.

Abstract
Renal cell carcinoma (RCC) is occasionally associated with vena cava involvement. Despite recent advances in therapeutic modalities, the 5-year survival in this population continues to be poor. Therefore, further studies are required to better characterize this patient population, especially from the clinicopathologic standpoint. A comprehensive review of patients with RCC and vena cava involvement managed at our institution from 2014 to 2022 was performed. Multiple clinicopathologic parameters including follow-up were obtained. A total of 114 patients were identified. The mean patient age was 63 years (range: 30-84 years). The cohort consisted of 78/114 (68%) males and 36/114 (32%) females. The mean primary tumor size (excluding tumor thrombus) was 11 cm. The majority of tumors (104/114, 91%) were unifocal. Tumor stages were categorized as follows: pT3b (51/114, 44%), pT3c (52/114, 46%), and pT4 (11/114, 10%). Most of the tumors were clear cell RCC 89/114 (78%), although other more aggressive RCC subtypes were also present. Most tumors were WHO/ISUP grade 3 (44/114, 39%) or 4 (67/114, 59%) with sarcomatoid differentiation present in 39/67 (58%). Necrosis was present in 94/114 (82%) tumors. Twenty-three of 114 (20%) tumors were categorized as pM1 and the ipsilateral adrenal gland was the most common site of metastasis. Of the 91 patients categorized as pM, not applicable at nephrectomy, 42/91 (46%) subsequently developed metastasis, most frequently to the lung. Of all patients, only 16/114 (14%) had positive vascular margins and 7/114 (6%) had positive soft tissue margins despite having very advanced disease and a subset considered inoperable at other centers.

Abstract
Renal cell carcinoma (RCC) is a common diagnosis, of which a notable portion of patients present with an extension into the venous circulation causing an inferior vena cava (IVC) tumor thrombus. Venous extension has significant implications for staging and subsequent treatment planning, with recommendations for more aggressive surgical removal, although associated surgical morbidity and mortality is relatively increased. The methods for surgical removal of RCC with IVC thrombus remain complex, particularly surrounding the use of robot-assisted surgery. Robot assistance for radical nephrectomy in this context is recently emerging. Thrombus level has important implications for surgical technique and prognosis. Other preoperative considerations may include location, laterality, size, and wall invasion. The urology literature on treatment of such tumors is largely limited to case series and institutional studies that describe the feasibility of various surgical options for these complex tumors. Further understanding of the outcomes and patient-specific risk factors would shed increased light on the optimal treatment for such cases. This narrative review provides a thorough overview on the previously reported use of robot-assisted nephrectomy in RCC with IVC thrombus to inform further studies which may optimize outcomes and guide shared decision-making.

Abstract
INTRODUCTION Some patients with renal cell carcinoma (RCC) present with venous tumor thrombus (VTT). The extent of the VTT is related to survival, so prompt surgical care is recommended. However, studies evaluating the natural history of VTT in patients with RCC are rare. We sought to evaluate the growth kinetics of VTT in patients with RCC using preoperative cross-sectional images. MATERIALS AND METHODS We identified patients who underwent radical nephrectomy and venous tumor thrombectomy at our institution from 01/2009 to 02/2022. We included those with a minimum of 2 adequate preoperative imaging studies (contrast-enhanced Computerized Tomography (CT), noncontrast Magnetic resonance imaging (MRI), or contrast-enhanced MRI), at least 14 days apart. We measured VTT in each study to calculate growth rate, and evaluated predictors of faster growth (demographics, histology, laterality, tumor diameter, and staging). To assess the relation between clinical variables and VTT growth, we used the Wilcoxon Rank-Sum, Kruskal-Wallis, and Spearman correlation tests. RESULTS A total of 30 patients were included in the analysis. The median time interval between studies was 33 days. Patients were mostly Caucasian and Males (90% and 70%, respectively). Most patients underwent a CT scan as their initial imaging study (66%), followed with an MRI as second study (73%). The mean venous tumor thrombus growth rate was 0.3 mm/d (standard deviation of 0.5mm), and only rhabdoid/sarcomatoid differentiation showed an association with tumor thrombus growth rate (0.3 vs. 0.63 mm/d, P = 0.038). CONCLUSIONS To the best of our knowledge, this is the first study evaluating the natural growth rate of venous tumor thrombus in patients with renal cell carcinoma. We found that tumor thrombi grew an average of 0.3 mm/d (1.0 cm/month) and that those with sarcomatoid and/or rhabdoid differentiation grew faster (0.63 mm/d). Further studies are needed to validate these results and provide a better understanding of tumor thrombus kinetics.

Abstract
OBJECTIVE To identify adhesive renal venous tumor thrombus (RVTT) of renal cell carcinoma (RCC) by contrast-enhancement CT (CECT). MATERIALS AND METHODS Our retrospective study included 53 patients who underwent preoperative CECT and pathologically confirmed RCC combined with RVTT. They were divided into two groups based on the intra-operative findings of RVTT adhesion to the venous wall, with 26 cases in the adhesive RVTT group (ARVTT) and 27 cases in the non-adhesive group (NRVTT). The location, maximum diameter (MD) and CT values of tumors, the maximum length (ML) and width (MW) of RVTT, and length of inferior vena cava tumor thrombus were compared between the two groups. The presence of renal venous wall involvement, renal venous wall inflammation, and enlarged retroperitoneal lymph node was compared between the two groups. A receiver operating characteristic curve was used to analyze the diagnostic performance. RESULTS The MD of RCC and the ML and MW of the RVTT were all larger in the ARVTT group than in the NRVTT group (p = 0.042, p < 0.001, and p = 0.002). The proportion of renal vein wall involvement and renal vein wall inflammation were higher in the ARVTT group than in NRVTT groups (both p < 0.001). The multivariable model including ML and vascular wall inflammation to predict ARVTT could achieve the best diagnostic performance with the area under the curve, sensitivity, specificity, and accuracy of 0.91, 88.5%, 96.3%, and 92.5%, respectively. CONCLUSION The multivariable model acquired by CECT images could be used to predict RVTT adhesion. CLINICAL RELEVANCE STATEMENT For RCC patients with tumor thrombus, contrast-enhanced CT could noninvasively predict the adhesion of tumor thrombus, thus predicting the difficulty of surgery and contributing to the selection of an appropriate treatment plan. KEY POINTS • The length and width of the tumor thrombus could be used to predict its adhesion to the vessel wall. • Adhesion of the tumor thrombus can be reflected by inflammation of the renal vein wall. • The multivariable model from CECT can well predict whether the tumor thrombus adhered to the vein wall.

The value of enhanced multiparameteric MRI diagnostic model for preoperatively predicting surgical methods of inferior vena cava in patients with renal tumors and inferior vena cava tumor thrombus. BMC Med Imaging 2023; 23:86. [PMID: 37355601 PMCID: PMC10290788 DOI: 10.1186/s12880-023-01043-0] [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: 11/02/2022] [Accepted: 06/05/2023] [Indexed: 06/26/2023] Open
Abstract
BACKGROUND Inferior vena cava tumor thrombus (IVCTT) invading the IVC wall majorly affects the surgical method choice and prognosis in renal tumors. Enhanced multiparameteric MRI plays an important role in preoperative evaluation. In this work, an MRI-based diagnostic model for IVCTT was established so as to guide the preoperative decisions. METHODS Preoperative MR images of 165 cases of renal tumors with IVCTT were retrospectively analyzed, and imaging indicators were analyzed, including IVCTT morphology and Mayo grade, IVCTT diameter measurements, bland thrombosis, primary MRI-based diagnosis of renal tumor, and involvement of contralateral renal vein. The indicators were analyzed based on intraoperative performance and resection scope of the IVC wall. Multivariate logistic regression analysis was used to establish the diagnostic model. RESULTS The morphological classification of the IVCTT, primary MRI-based diagnosis of renal tumors, maximum transverse diameter of IVCTT, and length of the bland thrombus were the main indexes predicting IVC wall invasion. The MRI-based diagnostic model established according to these indexes had good diagnostic efficiency. The prediction probability of 0.61 was set as the cutoff value. The area under the curve of the test set was 0.88, sensitivity was 0.79, specificity was 0.85, and prediction accuracy was 0.79 under the optimal cutoff value. CONCLUSION The preoperative MRI-based diagnostic model could reliably predict IVC wall invasion, which is helpful for better prediction of IVC-associated surgical operations.

Abstract
BACKGROUND To develop an efficient and stable canine model of IVC progressive obstruction at the renal hilus level. METHODS The model was established in two beagles by encircling an ameroid constrictor on the IVC at renal hilus level. Abdominal wall varicosity and animal weight variations were observed weekly after operation. Ultrasound examination was performed weekly after surgery to observe the AC position, the diameter and the velocity in the IVC. Six weeks after surgery, IVC angiography and CT scan were performed to observe the collateral circulation establishment and internal organ variation. Blood samples were taken regularly to monitor for variation in critical biochemical parameters. Renal biopsy was performed at 0, 2, 4, and 6 weeks after surgery. RESULTS Superficial varicose veins were observed on the abdominal wall at 2 weeks after surgery. Four weeks after operation, the IVC diameter increased by approximately 30%, whereas the IVC velocity decreased by more than 50%. Collateral circulation was observed by IVC angiography at 6 weeks through multiple dilated veins along with neovascularization. CT scan showed congestive alteration in the kidney. The body weight, kidney, and liver function were not significantly affected. Chronic congestive renal injury was detected in the renal tubular epithelium by kidney biopsy after surgery. CONCLUSIONS A canine model of IVC progressive obstruction at renal hilus level was stably and safely established for the first time by using an AC, which may be helpful for preserving pivotal collateral circulation and non-tumor side kidney function in the IVC thrombus surgery.

Abstract
Artificial intelligence is rapidly expanding into nearly all facets of life, particularly within the field of medicine. The diagnosis, characterization, management, and treatment of kidney cancer is ripe with areas for improvement that may be met with the promises of artificial intelligence. Here, we explore the impact of current research work in artificial intelligence for clinicians caring for patients with renal cancer, with a focus on the perspectives of radiologists, pathologists, and urologists. Promising preliminary results indicate that artificial intelligence may assist in the diagnosis and risk stratification of newly discovered renal masses and help guide the clinical treatment of patients with kidney cancer. However, much of the work in this field is still in its early stages, limited in its broader applicability, and hampered by small datasets, the varied appearance and presentation of kidney cancers, and the intrinsic limitations of the rigidly structured tasks artificial intelligence algorithms are trained to complete. Nonetheless, the continued exploration of artificial intelligence holds promise toward improving the clinical care of patients with kidney cancer.

Abstract
PURPOSE OF REVIEW Herein we provide a review of intravascular ultrasound (IVUS) and its ability to assist in the evaluation and surgical management of advanced retroperitoneal, genitourinary tumors. RECENT FINDINGS Advanced retroperitoneal tumors such as advanced renal cell carcinoma, bulky retroperitoneal lymphadenopathy associated with advanced testicular carcinoma, large adrenal tumors, and retroperitoneal sarcomas can invade, compress, or distort vascular anatomy making surgical resection challenging and high risk. Intravascular ultrasonography is commonly used by vascular and cardiothoracic surgery to provide a real time assessment of vascular invasion, compression, and aberrant anatomy to assist with pre-operative and/or intraoperative decision-making. However, the application of this technology to assist with cancer surgery has been limited. The use of intravascular ultrasound prior to radical, extirpative, retroperitoneal surgery involving large vessels can aid in the planning and execution of such challenging operations.

Influence of Deep Invasive Tumor Thrombus on the Surgical Complexity and Prognosis of Patients With Non-Metastatic Renal Cell Carcinoma Combined With Venous Tumor Thrombus. Front Oncol 2022; 12:833780. [PMID: 35223514 PMCID: PMC8865079 DOI: 10.3389/fonc.2022.833780] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Accepted: 01/03/2022] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND To evaluate the impact of deep invasive tumor thrombus (DITT) on the surgical complexity and prognosis of patients with renal cell carcinoma with venous tumor thrombus. METHODS We retrospectively reviewed clinical data of 138 patients with non-metastatic renal cell carcinoma combined with venous tumor thrombus, who underwent surgical treatment in Peking University Third Hospital from January 2015 to June 2020. Patients were divided into the DITT group (84 patients) and non-invasive tumor thrombus (NITT) group (54 patients). Chi-square, t-test and Mann-Whitney U test were used for categorical and continuous variables, respectively. Kaplan-Meier plots were performed to evaluate the influence of DITT. Univariable and multivariable Cox regressions were conducted to determine independent prognostic factors and then assembled to make a nomogram to predict the survival. The performance of the nomogram was evaluated by Harrell's consistency index (C-index) and calibration plot. RESULTS Deep invasive tumor thrombus significantly increased the difficulty of surgery for patients with renal cell carcinoma with venous tumor thrombus, which is mainly reflected in longer operation time (p < 0.001), more surgical bleeding (p < 0.001), a higher proportion of perioperative blood transfusion (p = 0.006), a higher proportion of open surgery (p = 0.001), a longer postoperative hospital stay (p = 0.003), and a higher proportion of postoperative complications (p = 0.001). DITT (hazard ratio [HR] = 2.781, p = 0.040) was one of the independent risk factors for worse prognosis. Multivariate analysis showed that sarcoma-like differentiation (p = 0.040), tumor thrombus invasion (p = 0.040), low hemoglobin (p = 0.003), and pathological type (p < 0.001) were independent prognostic factors. The nomogram, combining all these predictors, showed powerful prognostic ability with a C-index of 78.8% (CI: 71.2%-86.4%). The predicted risk closely matches the observed recurrence probability. CONCLUSION Deep invasive tumor thrombus significantly increased the difficulty of surgeries for patients of renal cell carcinoma with venous tumor thrombus, and may lead to poor prognosis.

Zhu AH, Hou XY, Tian S, Zhang WF. Diagnostic value of 18F-FDG PET/CT versus contrast-enhanced MRI for venous tumour thrombus and venous bland thrombus in renal cell carcinoma. Sci Rep 2022; 12:587. [PMID: 35022440 PMCID: PMC8755813 DOI: 10.1038/s41598-021-04541-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Accepted: 12/20/2021] [Indexed: 11/09/2022] Open
Abstract
The purpose of this study was to compare the ability of 18F-FDG PET/CT and contrast-enhanced MRI (CEMRI) to detect and grade venous tumour thrombus (VTT) and venous bland thrombus (VBT) in RCC and assess invasion of the venous wall by VTT. The PET/CT and CEMRI data of 41 patients with RCC were retrieved. The difference in maximum standardized uptake value (SUVmax) between VTT and VBT was analysed. According to their pathological diagnosis, the patients were divided into those with and without venous wall invasion. The PET/CT and CEMRI features, including the SUVmax of the primary lesion and VTT, maximum venous diameter, complete occlusion of the vein by VTT, and VTT morphology, were compared between the two groups. All 41 patients had VTT, and eleven of the 41 patients had VBT. The mean SUVmax of the VTT (6.33 ± 4. 68, n = 41) was significantly higher than that of the VBT (1.37 ± 0.26, n = 11; P < 0.001). Ten of the 11 cases of VBT were correctly diagnosed by 18F-FDG PET/CT, and all 11 were diagnosed by CEMRI. Both 18F-FDG PET/CT and CEMRI can effectively detect VTT and distinguish VTT from VBT. 18F-FDG PET/CT is less effective in grading VTT than CEMRI. Complete venous occlusion by VTT indicates venous wall invasion.

Abstract
Retroperitoneal sarcomas often require complex surgical procedures in order to achieve complete resection; in such cases both vascular and visceral resections are needed. When it comes to the need for vascular reconstruction, the type of graft as well as the type of reconstructive process are chosen according to the length and location of the resected segment. Meanwhile, depending on the location of the resected segment, other vascular reconstructions may be needed such as the reimplantation of the renal veins. However, in certain cases, this reimplantation is not mandatory, an adequate renal outflow being reported through the collateral network at this level. We present the case of a 43-year-old patient diagnosed with a large retroperitoneal sarcoma originating from the cava vein invading the right kidney. Resection of the tumor was performed en bloc with caval resection and right nephrectomy, without reimplantation of the left renal vein at the level of the graft. Extended visceral and vascular resections might be needed in order to achieve complete resection of inferior cava vein sarcomas; re-implantation of the left renal vein being not mandatory if rich collateral circulation is present.

Abstract
Background Currently, immunotherapy is indicated for patients with metastatic RCC or unresectable RCC, but there is no indication for immunotherapy in the neoadjuvant setting. We report a case in which the combined use of nivolumab and ipilimumab and sequential TKI therapy enabled surgical treatment.
Case presentation A 71-year-old female was diagnosed with a metastatic clear-cell renal cell carcinoma with a level IV tumor thrombus. She was started on nivolumab-ipilimumab therapy, and was switched to pazopanib monotherapy because the tumor thrombus progressed within the right atrium. The tumor shrank to resectable status with sequential therapy. She then underwent right nephrectomy and thrombectomy. Pathological analysis showed 10–20% residual tumor in the primary tumor, but no viable cells in tumor thrombus. She remains clinically disease-free 1 year after surgery. Conclusion This case suggests the utility of sequential immune-targeted therapy as neoadjuvant therapy in advanced renal cell carcinoma.

Abstract
OBJECTIVE To evaluate the impact of deep invasive tumor thrombus on the surgical complexity and prognosis of patients with renal cell carcinoma complicated with inferior vena cava tumor thrombus. METHODS We retrospectively reviewed the clinical data of 94 patients with non-metastatic renal cell carcinoma complicated with inferior vena cava tumor thrombus, who underwent surgical treatment in Peking University Third Hospital from January 2017 to June 2020. The patient's general condition, clinicopathological characteristics, surgery and survival information were collected. The patients were divided into two groups based on the intra-operative findings of tumor thrombus adhesion to the venous wall, of which 64 cases were in the deep invasive tumor thrombus (DITT) group and 30 cases were in the non-invasive tumor thrombus (NITT) group. Chi-square, t test and Mann-Whitney U test were used for categorical and continuous variables respectively. Kaplan-Meier plots and multivariable Cox regressions were performed to evaluate the influence of DITT on the prognosis of the patients with renal cell carcinoma with inferior vena cava tumor thrombus. RESULTS DITT significantly increase the difficulty of surgery for the patients with renal cell carcinoma with venous tumor thrombus, which was mainly reflected in the longer operation time (362.5 vs. 307.5 min, P=0.010), more surgical bleeding (1 200 vs. 450 mL, P=0.006), more surgical blood transfusion (800 vs. 0 mL, P=0.021), more plasma transfusion (200 vs. 0 mL, P=0.001), a higher proportion of open surgery (70.3% vs. 36.7%, P=0.002), a longer post-operative hospital stay (9.5 vs. 8 days, P=0.036), and a higher proportion of post-operative complications (46.9% vs. 13.8%, P=0.002). DITT was associated with worse overall survival of the patients with renal cell carcinoma with inferior vena cava tumor thrombus (P=0.022). Even in the multivariate analysis, DITT was still a poor prognostic factor for the overall survival of these patients [HR: 4.635 (1.017-21.116), P=0.047]. CONCLUSION For patients with non-metastatic renal cell carcinoma with inferior vena cava tumor thrombus, DITT will significantly increase the difficulty of surgery, and may lead to poor prognosis.

Abstract
Introduction. Renal cell carcinoma can invade through the renal vein into the inferior vena cava, and can extend intraluminally, with tumor-thrombus formation. Methods: Retrospective study from January 2003 to August 2016. Surgical outcomes were analyzed. Neves classification was used for patient categorization. Kaplan Meier and Log-Rank test were used for survival analysis. Results: A total of 134 patients were included, 69 males (51.4%) and 65 females (49%), M:F ratio 1.06:1. Tumor size, bleeding and surgical time were higher in level IV thrombi (mean 16.1cm, 3 064ml and 6.5hrs, respectively), compared to level I (8.5cm, 1033ml and 3.1hrs, respectively). A higher frequency of positive lymph nodes was observed in levels III and IV compared with levels I and II (49% vs. 17.7%, p=0.0001). Distant metastases were observed in 36 pts. (27%). Overall surgical mortality was 4.5%. 5-year overall survival was 63%. We observed a 5-year survival in patients with level I-II 82% and level III and IV 46%. Conclusions: Our results suggest the benefit for the patient of an aggressive surgical approach with an acceptable mortality and 5-year survival rate. The results obtained justify an aggressive surgical approach to these tumors.

Abstract
This article reviews the essential role of imaging in clinical staging and restaging of renal cell carcinoma (RCC). To completely characterize and stage an indeterminate renal mass, renal CT or MRI without and with IV contrast administration is recommended. The critical items for initial clinical staging of an indeterminate renal mass or of a known RCC according to the TNM staging system are tumor size, renal sinus fat invasion, urinary collecting system invasion, perinephric fat invasion, venous invasion, adrenal gland invasion, invasion of the perirenal (Gerota) fascia, invasion into other adjacent organs, the presence of enlarged or pathologic regional (retroperitoneal) lymph nodes, and the presence of distant metastatic disease. Larger tumor size is associated with higher stage disease and invasiveness, lymph node spread, and distant metastatic disease. Imaging practice guidelines for clinical staging of RCC, as well as the role of renal mass biopsy, are highlighted. Specific findings associated with response of advanced cancer to antiangiogenic therapy and immunotherapy are discussed, as well as limitations of changes in tumor size after targeted therapy. The accurate clinical staging and restaging of RCC using renal CT or MRI provides important prognostic information and helps guide the optimal management of patients with RCC.

Abstract
OBJECTIVES To assess the impact of the presence of bland thrombus (BT) on prognosis of patients treated with resection of renal cell carcinoma (RCC) with inferior vena cava tumor thrombus (IVCTT). MATERIALS AND METHODS The medical records of a total of 145 consecutive postsurgical RCC patients with level I-IV IVCTT were reviewed from January 2008 to August 2018. Associations of BT with clinicopathological variables were estimated by chi-square test or Student's t-test. Kaplan-Meier method and multivariate Cox proportional hazard model were used. The eighth TNM staging system, "Spiess PE" model, University of California at Los Angeles Integrated Staging System and Stage, Size, Grade, and Necrosis (SSIGN) score were selected to assess whether BT could improve their predictive abilities. RESULTS BT was observed in 34 (23.4%) patients and was significantly associated with increased levels of IVCTT (P = 0.004) and invasion of IVC wall (P = 0.030). Multivariable Cox analyses revealed that tumor grade, T stage, M stage, tumor thrombus consistency and BT were independent risk factors for both progression-free survival and overall survival. The concordance indexes ranged from a low of 0.652 in TNM to a high of 0.731 in SSIGN, and integrating BT into each base model led to an increased predictive accuracies of 6.2% for TNM (P = 0.025), 4.0% for "Spiess PE" model (P = 0.069), 2.1% for University of California at Los Angeles Integrated Staging System (P = 0.149) and 1.2% for SSIGN (P = 0.290), respectively. CONCLUSIONS Presence of BT was independently associated with survival in postsurgical patients with RCC-IVCTT. Routine consideration of BT as an adjunct to TNM staging system may be suggested.

Abstract
Persistent inferior vena cava (IVC) tumor thrombus in Wilms tumor patients represents a management challenge. We describe three pediatric cases with preoperative evaluation documenting complete IVC occlusion and well-developed collaterals. They underwent nephrectomy and tumor thrombus removal accomplished with circumferential resection of the retrohepatic IVC without vascular reconstruction. All patients are asymptomatic and disease-free at 9, 2.5, and 2 years after stopping therapy. Cavectomy without reconstruction is safe and well tolerated in Wilms tumor patients with completely occlusive IVC tumor thrombus. Additionally, when performed en bloc with nephrectomy and with clear margins, cavectomy obviates the need for radiotherapy per protocol.

Abstract
PURPOSE OF REVIEW The aim of this review is to describe the preoperative evaluation, surgical techniques, and postoperative management of patients with renal cell carcinoma (RCC) undergoing radical nephrectomy (RN) and inferior vena cava (IVC) thrombectomy. RECENT FINDINGS RN and IVC thrombectomy remains the standard management option in non-metastatic RCC patients with IVC thrombus. A comprehensive preoperative workup, including high-quality imaging, blood works, and appropriate consultations are required for all patients. The aim of the surgery is complete resection of all tumor burden, which requires a skillful surgical team for such a challenging procedure and is inherently associated with a high rate of perioperative morbidity and mortality. Preoperative CT or MRI is essential for surgical planning. The surgical approach is mainly determined by the level of the tumor thrombus. The open approach has been the standard, though minimally invasive and robotic techniques are emerging in selected cases by experienced surgeons.

A Predictive Model for Tumor Invasion of the Inferior Vena Cava Wall Using Multimodal Imaging in Patients with Renal Cell Carcinoma and Inferior Vena Cava Tumor Thrombus. BIOMED RESEARCH INTERNATIONAL 2020; 2020:9530618. [PMID: 33083491 PMCID: PMC7563051 DOI: 10.1155/2020/9530618] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 08/14/2020] [Accepted: 08/24/2020] [Indexed: 11/17/2022]
Abstract
Purpose Developed a preoperative prediction model based on multimodality imaging to evaluate the probability of inferior vena cava (IVC) vascular wall invasion due to tumor infiltration. Materials and Methods We retrospectively analyzed the clinical data of 110 patients with renal cell carcinoma (RCC) with level I-IV tumor thrombus who underwent radical nephrectomy and IVC thrombectomy between January 2014 and April 2019. The patients were categorized into two groups: 86 patients were used to establish the imaging model, and the data validation was conducted in 24 patients. We measured the imaging parameters and used logistic regression to evaluate the uni- and multivariable associations of the clinical and radiographic features of IVC resection and established an image prediction model to assess the probability of IVC vascular wall invasion. Results In all of the patients, 46.5% (40/86) had IVC vascular wall invasion. The residual IVC blood flow (OR 0.170 [0.047-0.611]; P = 0.007), maximum coronal IVC diameter in mm (OR 1.203 [1.065-1.360]; P = 0.003), and presence of bland thrombus (OR 3.216 [0.870-11.887]; P = 0.080) were independent risk factors of IVC vascular wall invasion. We predicted vascular wall invasion if the probability was >42% as calculated by: {Ln [Pre/(1 - pre)] = 0.185 × maximum cornal IVC diameter + 1.168 × bland thrombus-1.770 × residual IVC blood flow-5.857}. To predict IVC vascular wall invasion, a rate of 76/86 (88.4%) was consistent with the actual treatment, and in the validation patients, 21/26 (80.8%) was consistent with the actual treatment. Conclusions Our model of multimodal imaging associated with IVC vascular wall invasion may be used for preoperative evaluation and prediction of the probability of partial or segmental IVC resection.

Abstract
Background Renal cell carcinoma (RCC) has the propensity to lead to venous tumor thrombus (VTT). Nephrectomy with tumor thrombectomy is an effective treatment option but is a technically challenging surgical procedure that is accompanied by a high rate of complications. The aims of this study were to investigate pre-operative imaging parameters for the assessment of inferior vena cava (IVC) wall invasion due to a tumor thrombus in patients with RCC and to identify predictors from the intra-operative findings. Methods Clinical and imaging data were collected from 110 patients who underwent nephrectomy with IVC tumor thrombectomy (levels I–IV) for RCC and IVC tumor thrombus at the Peking University Third Hospital between May 2015 and March 2018. Univariable and multivariable logistic regression and receiver operating characteristic curves were used to assess the correlations between pre-operative imaging features and intra-operative macroscopic invasions of the IVC wall by tumor thrombus. Results Among the 110 patients, 41 underwent partial or segmental resection of IVC. There were univariate associations of pre-operative imaging parameters that could be used to predict the need for IVC resection, including those of the Mayo classification, maximum anterior-posterior (AP) diameter of the renal vein at the renal vein ostium (RVo), maximum AP diameter of the VTT at the RVo and IVC occlusion. For the multivariable analysis, the AP diameter of the VTT at the RVo and IVC occlusion were associated with a significantly increased risk of invasion of the IVC wall by tumor thrombus. The optimum imaging thresholds included an AP diameter of the VTT at the RVo larger than 17.0 mm and the presence of IVC occlusion, with which we predicted invasions of the IVC wall requiring IVC resection. The probabilities of intra-operative IVC resection for patients without both independent factors, with an AP diameter of the VTT at the RVo larger than 17.0 mm, with IVC occlusion, and with both concurrent factors were 5%, 23%, 56%, and 66%, respectively. Conclusion An increase in the AP VTT diameter at the RVo and the presence of complete occlusion of the IVC are independent risk factors for a high probability of IVC wall invasion by tumor thrombus.

Risks from Deferring Treatment for Genitourinary Cancers: A Collaborative Review to Aid Triage and Management During the COVID-19 Pandemic. Eur Urol 2020; 78:29-42.

Abstract
Context The coronavirus disease 2019 (COVID-19) pandemic is leading to delays in the treatment of many urologic cancers. Objective To provide a contemporary picture of the risks from delayed treatment for urologic cancers to assist with triage. Evidence acquisition A collaborative review using literature published as of April 2, 2020. Evidence synthesis Patients with low-grade non–muscle-invasive bladder cancer are unlikely to suffer from a 3–6-month delay. Patients with muscle-invasive bladder cancer are at risk of disease progression, with radical cystectomy delays beyond 12 wk from diagnosis or completion of neoadjuvant chemotherapy. Prioritization of these patients for surgery or management with radiochemotherapy is encouraged. Active surveillance should be used for low-risk prostate cancer (PCa). Treatment of most patients with intermediate- and high-risk PCa can be deferred 3–6 mo without change in outcomes. The same may be true for cancers with the highest risk of progression. With radiotherapy, neoadjuvant androgen deprivation therapy (ADT) is the standard of care. For surgery, although the added value of neoadjuvant ADT is questionable, it may be considered if a patient is interested in such an approach. Intervention may be safely deferred for T1/T2 renal masses, while locally advanced renal tumors (≥T3) should be treated expeditiously. Patients with metastatic renal cancer may consider vascular endothelial growth factor targeted therapy over immunotherapy. Risks for delay in the treatment of upper tract urothelial cancer depend on grade and stage. For patients with high-grade disease, delays of 12 wk in nephroureterectomy are not associated with adverse survival outcomes. Expert guidance recommends expedient local treatment of testis cancer. In penile cancer, adverse outcomes have been observed with delays of ≥3 mo before inguinal lymphadenectomy. Limitations include a paucity of data and methodologic variations for many cancers. Conclusions Patients and clinicians should consider the oncologic risk of delayed cancer intervention versus the risks of COVID-19 to the patient, treating health care professionals, and the health care system. Patient summary The coronavirus disease 2019 pandemic has led to delays in the treatment of patients with urologic malignancies. Based on a review of the literature, patients with high-grade urothelial carcinoma, advanced kidney cancer, testicular cancer, and penile cancer should be prioritized for treatment during these challenging times.

Abstract
OBJECTIVE To present our preliminary experience of robotic left radical nephrectomy (LRN) and segmental inferior vena cava (IVC) resection without caval replacement for left renal cell carcinoma (RCC) with inferior vena cava tumor thrombus. MATERIALS AND METHODS Between 2017 and 2018, 7 patients underwent segmental IVC resection and LRN robotically. All patients underwent preoperative cavography, demonstrating complete IVC occlusion. Computed tomography-based 3-dimensional reconstruction revealed sufficient collateralization of the IVC and right renal vein (RRV). The cephalic IVC was circumferentially resected and ligated just below the second porta hepatis. The caudal IVC was circumferentially resected above the RRV with preservation of the major collaterals. The RRV was not dissected during the procedure to avoid compromising its neocollaterals. The IVC portion between the RRV and the second porta hepatis was removed en bloc with the tumor thrombus, and the LRN was performed. RESULTS All cases were successfully performed by robotic surgery without conversion. Median operative time was 420 minutes. Median intensive care unit stay was 3 days. Four grade Ⅱ complications occurred in 2 patients. One patient had mild LEE postoperatively and recovered without special medication. Median preoperative and 3-6 months follow-up serum creatinine was 118.7 μmol/L and 135.2 μmol/L, respectively. No patient needed dialysis postoperatively. One case occurred disease progression. No patient died during the follow-up period. CONCLUSION Robotic segmental IVC resection for left RCC with inferior vena cava tumor thrombus is feasible in well-selected cases. Three-dimensional reconstruction and cavography are helpful in the preoperative evaluation of neocollaterals in patients with suprarenal IVC occlusion.

Abstract
OBJECTIVE To describe the feasibility and perioperative outcome of suprarenal resection of inferior vena cava (IVC) in urologic neoplasms without reconstruction. METHODS We retrospectively reviewed the patients who underwent suprarenal resection of IVC without reconstruction for urologic neoplasms in our institution between September 2010 and October 2019. Patients' demographic, clinical, radiologic, and 90-day perioperative complications were recorded. RESULTS Twenty-eight (79% male) patients with a median age of 59 (25-75) years were included in the study. Twenty-five (89%) of patients had renal cell carcinoma, 1 had renal leiomyosarcoma, and 2 had metastatic testicular teratoma. Twenty-two patients had Mayo level 3 thrombus, 3 had level 2, and 3 had level 4. The mean radiologic thrombus length was 12.6 cm. Eleven patients had radiologic bland thrombosis in the infrarenal IVC. Twenty-seven patients underwent open, and 1 robotic surgery. The median operating time was 411 (range 240-808) minutes, median blood loss was 3750 cc, and all but 1 patient received perioperative transfusion (median 11 units of packed red blood cells). Median hospital stay was 5 (3-50) days. Ninety-day complication rate was 35% (Clavien-Dindo grade I/II and III/IV were 21% and 14%, respectively). Four patients (14%) developed transient nondisabling leg edema. The 90-day mortality rate was 7%. CONCLUSION Suprarenal inferior vena cava resection without reconstruction is feasible, yet high-risk operation that should be performed in experienced centers in selected patients with urologic malignancies.

Abstract
Extension of tumor tissue within a vein is a recognized prognostic factor in abdominal malignancy because of its influence on tumor staging and selection of therapeutic management. With the advent of newer surgical techniques, and variable treatment strategies, imaging plays a crucial role in categorizing patients according to the tumor resectability and vascular reconstruction techniques during surgery. Understanding the clinical impact of tumor thrombus increases the awareness of the radiologist about the key findings in tumor staging and decision-making of surgical approach. Ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) can be used individually and in combination to accurately assess the tumor thrombus. In our pictorial review, we will discuss the imaging findings and clinical consequences of tumor thrombosis in abdominal malignancies, including hepatocellular carcinoma, pancreatic neuroendocrine tumor, renal cancer, and adrenal cortical carcinoma.

Abstract
Endovenous tumor thrombus in abdomen should be accurately diagnosed as it is a significant finding that may change medical and surgical treatment approaches. As some underlying reasons for endovenous tumor thrombi are relatively rare and imaging findings may be quite subtle, they can be easily overlooked which may have important clinical consequences. In this paper, we described the various imaging aspects of endovenous tumor thrombi originating from various tumor types in different venous structures of the abdomen.

Abstract
Background: Radical nephrectomy with thrombectomy is one of the most difficult and complicated urological operations. But the roles of renal tumor volume and thrombus level in surgical complexity and prognostic outcome are not clear. This study aimed to evaluate the surgical complexity and prognostic outcome between the volume of renal cell carcinoma (RCC) and the level of venous tumor thrombus. Methods: The clinical data of 67 RCC cases with renal vein or inferior vena cava (IVC) tumor thrombus from January 2015 to May 2018 were retrospectively analyzed. Among these 67 cases, 21 (31.3%) were small tumors with high-level thrombus (tumor ≤7 cm in diameter and thrombus Neves Level II–IV), while 46 (68.7%) were large tumors with low-level thrombus group (tumor >7 cm in diameter and thrombus Level 0–I). Clinical features, operation details, and pathology data were collected. Univariable and multivariable logistic regression analyses were applied to evaluate the risk factors for small tumor with high-level thrombus. Results: Patients with small tumors and high-level thrombus were more likely to have longer operative time (421.9 ± 135.1 min vs. 282.2 ± 101.9 min, t = 4.685, P < 0.001), more surgical bleeding volume (1200 [325, 2900] mL vs. 500 [180, 1000] mL, U = 270.000, P = 0.004), more surgical blood transfusion volume (800 [0, 1400] mL vs. 0 [0, 800] mL, U = 287.500, P = 0.004), more plasma transfusion volume (0 [0, 800] mL vs. 0 [0, 0] mL, U = 319.000, P = 0.004), higher percentage of open operative approach (76.2% vs. 32.6%, χ2 = 11.015, P = 0.001), higher percentage of IVC resection (33.3% vs. 0%, χ2 = 17.122, P < 0.001), and higher percentage of post-operative complications (52.4% vs. 19.6%, χ2 = 7.415, P = 0.010) than patients with large tumors and low-level thrombus. In multivariate analysis, decreased hemoglobin (Hb) (odds ratio [OR]: 0.956, 95% confidence interval [CI]: 0.926–0.986, P = 0.005) and non-sarcomatoid differentiation (OR: 0.050, 95% CI: 0.004–0.664, P = 0.023) were more likely to form small tumors with high-level tumor thrombus rather than large tumor with small tumor thrombus. The estimated mean cancer-specific survival times of small tumor with high-level thrombus and large tumor with low-level thrombus were 31.6 ± 3.8 months and 32.5 ± 2.9 months, without statistical significance (P = 0.955). After univariate and multivariate Cox proportional hazard survival regression analyses, only distant metastasis (hazard ratio [HR]: 3.839, P = 0.002), sarcomatoid differentiation (HR: 7.923, P < 0.001), alkaline phosphatase (HR: 2.661, P = 0.025), and severe post-operative complications (HR: 10.326, P = 0.001) were independent predictors of prognosis. Conclusions: The level of the tumor thrombus was more important than the diameter of the primary kidney tumor in affecting the complexity of surgery. In the same T3 stage, neither the renal tumor diameter nor the tumor thrombus level was an independent risk factor for prognosis.

Abstract
Background Vena cava thrombus is one of the main clinical manifestations of locally aggressive renal cell carcinoma (RCC). Inferior vena cava (IVC) wall invasion and presence of bland thrombus could affect the surgical outcome. This study aims to assess the value of contrast-enhanced ultrasound (CEUS) in detecting wall invasion and differentiating bland thrombus from tumor thrombus during robot-assisted IVC thrombectomy for RCC. Methods The intraoperative CEUS findings of 60 patients with RCC accompanied by IVC tumor thrombus were retrospectively analyzed. The CEUS features were compared with the intra- and post-operative pathological findings. CEUS in patients with wall invasion showed that the tumor thrombus was enhanced synchronously with the IVC wall, and the continuity of the IVC wall was lost. In contrast, in patients without wall invasion, CEUS showed that the contrast agent could pass between the tumor thrombus and the IVC wall, and the continuity of IVC wall was good. Typically, contrast-enhanced perfusion was seen in tumor thrombus but not in bland thrombus. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CEUS were statistically analyzed. Results The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of the typical enhancement mode of CEUS were 93.1, 93.5, 93.3, 93.1, and 93.5% in identifying wall invasion and 100, 96, 96.7, 83.3, and 100% in differentiating bland thrombus from tumor thrombus, respectively. There were excellent inter-observer agreements for identifying IVC wall invasion and differentiating bland thrombus from tumor thrombus with kappa coefficients of 0.90 and 0.97. Conclusions The present study indicates that intraoperative CEUS plays an important role in robot-assisted IVC thrombectomy for RCC. It can detect wall invasion and differentiate bland thrombus from tumor thrombus, thus offering real-time information to the operator during surgery.

Abstract
OBJECTIVE To evaluate the diagnostic performance of MRI for the assessment of inferior vena cava (IVC) wall invasion by IVC thrombus in patients with renal cell carcinoma (RCC). METHODS We retrospectively collected patients who underwent radical nephrectomy and thrombectomy for RCC between 2010 and 2018 at Peking University First Hospital. All the patients underwent imaging on a 1.5 Tesla or 3.0 Tesla MRI scanner. Fifty-six patients met the inclusion criteria. Preoperative imaging was reviewed by two radiologists blinded to details of the patient's surgical procedure and histopathology. Two radiologists measured the maximum anterior-posterior diameter and coronal diameters of the IVC and renal vein, and the craniocaudal extent of tumor thrombus, and evaluated the MRI features of IVC thrombus, including occlusion of the IVC lumen, the margin of the tumor thrombus (smooth vs. irregular), contact of the IVC thrombus and IVC wall, and altered signal of the IVC wall. Univariable and multivariable associations of clinical and radiographic features with IVC wall invasion were evaluated by Logistic regression. RESULTS Of the 56 patients [male: 43, female: 13, mean age: (55.64±0.43) years], 17 (30.36%) were detected with IVC wall invasion, and most were clear cell carcinoma. Tumor thrombus with IVC wall invasion showed an increase in length of IVC thrombus [(7.91±3.59) cm vs. (5.94±3.57) cm, P=0.049], and more features of complete occlusion of the IVC lumen (P=0.002), irregular margin of the IVC thrombs (P=0.005), contact of the IVC thrombus and IVC wall (P=0.001), and altered signal of the low-intensity vessel wall (P<0.001), with a sensitivity of 94.12% and a specificity of 79.49%. CONCLUSION The present study indicates that MRI could be a means of evaluating RCC with IVC wall invasion, and the combination of tumor thrombus length and subjective impression of IVC wall invasion achieved a high sensitivity and specificity for diagnosis.

Abstract
The inferior vena cava (IVC) is the largest venous conduit below the diaphragm. Although this structure is often overlooked both clinically and radiographically, it can be involved in many different pathologic processes. A thorough understanding of the IVC will assist the radiologist in recognizing anatomic variants, identifying abnormalities, and providing accurate differential diagnoses. In this comprehensive pictorial review of the IVC, we depict embryology behind anatomic variants, present a wide range of pathology with a focus on diagnostic imaging, and describe relevant endovascular interventions.

Abstract
Objective To define preoperative clinical and radiographic risk factors for the need of inferior vena cava (IVC) resection in patients with renal cell carcinoma (RCC) and IVC tumor thrombus. Methods We reviewed data of 121 patients with renal cell carcinoma and venous tumor thrombus receiving radical nephrectomy and thrombectomy at our institution between 2015 and 2017, and 86 patients with Mayo I–IV level tumor thrombus were included in the final analysis. Clinical features, operation details, and pathology data were collected. Preoperative images were reviewed separately by two radiologists. Univariable and multivariable logistic regression analyses were applied to evaluate clinical and radiographic risk factors of IVC resection. Results Of the 86 patients, 44 (51.2%) received IVC resection during thrombectomy. In univariate analysis, we found that body mass index (BMI) (odds ratio [OR] = 1.22, P = 0.003), primary tumor diameter (OR = 0.84, P = 0.022), tumor thrombus width (OR = 1.08, P = 0.037), tumor thrombus level (OR = 1.57, P = 0.030), and IVC occlusion (OR = 2.67, P = 0.038) were associated with the need for resection of the IVC. After adjusting for the other factors, BMI (OR = 1.18, P = 0.019) was the only significant risk factor for IVC resection. Multivariable analysis in Mayo II–IV subgroups confirmed BMI as an independent risk factor (OR = 1.26, P = 0.024). A correlation between BMI and the width (Pearson’s correlation coefficient [PCC] = 0.27, P = 0.014) and length (PCC = 0.23, P = 0.037) of the tumor thrombus was noticed. Conclusion We identified BMI as an independent risk factor for IVC resection during thrombectomy of RCC with tumor thrombus in a Chinese population. More careful preoperative preparation for the IVC resection and/or reconstruction is warranted in patients with higher BMI.

Abstract
New developments in cross-sectional imaging, including contrast-enhanced ultrasound, dual-energy computed tomography, multiparametric magnetic resonance imaging, single-photon emission computed tomography, and positron emission tomography, together with novel application of existing and novel radiotracers, have changed the landscape of renal mass characterization (ie, virtual biopsy) as well as the detection of metastatic disease, prognostication, and response assessment in patients with advanced kidney cancer. A host of imaging response criteria have been developed to characterize the response to targeted and immune therapies and correlate with patient outcomes, each with strengths and limitations. Recent efforts to advance the field are aimed at increasing objectivity with quantitative techniques and the use of banks of imaging data to match the vast genomic data that are becoming available. The emerging field of radiogenomics has the potential to transform further the role of imaging in kidney cancer management through eventual noninvasive characterization of the tumor histology and genetic microenvironment in single renal masses and/or metastatic disease. We review of the effect of currently available imaging techniques in the management of patients with kidney cancer, including localized, locally advanced, and metastatic disease.

Abstract
OBJECTIVE Advanced renal cell carcinoma (RCC) has a significant predisposition to vascular invasion. Tumor vascular invasion and thrombus are found in the renal vein and the inferior vena cava (IVC) in up to 10% to 25% of patients. This study reviewed the current status of radical nephrectomy with IVC thrombectomy for advanced RCC. METHODS A two-level search strategy of the literature (MEDLINE, PubMed, The Cochrane Library, and Google Scholar) for relevant articles listed between January 2000 and December 2015 was performed. The review was confined to patients with primary RCC associated with vascular invasion. RESULTS Untreated RCC with intravascular thrombus has a median survival of 5 months. Surgical exposure and intervention are tailored to the level of tumor thrombus. The 30-day mortality for radical nephrectomy with IVC thrombectomy is low (1.5%-10%), and the complication rates have been reported to be 18%, 20%, 26%, and 47% for IVC tumor thrombus level I, II, III, and IV disease, respectively. Disease-specific survival ranges from 40% to 60% at 5 years after nephrectomy and removal of the intravascular tumor. CONCLUSIONS Radical nephrectomy with IVC thrombectomy is an effective cancer control operation that can be safely performed with acceptable mortality and morbidity. Preoperative imaging coupled with perioperative surgical management of the IVC is critical to procedural success and patient outcomes.

Abstract
BACKGROUND Renal cell carcinoma (RCC) are accompanied by inferior vena cava (IVC) thrombus in up to 10% of the cases, with surgical resection remaining the only curative option. In case of IVC wall invasion, the operative procedure is more challenging and may even require IVC resection. This study aims to determine the diagnostic performance of contrast-enhanced magnetic resonance imaging (MRI) for the assessment of wall invasion by IVC thrombus in patients with RCC, validated with intraoperative findings. METHODS Data were collected on 81 patients with RCC and IVC thrombus, who received a radical nephrectomy and vena cava thrombectomy between February 2008 and November 2017. Forty eight patients met the inclusion criteria. Sensitivity and specificity as well as the positive and negative predictive values were calculated for preoperative MRI, based on the assessments of the two readers for visual wall invasion. Furthermore, a logistic regression model was used to determine if there was an association between intraoperative wall adherence and IVC diameter. RESULTS Complete occlusion of the IVC lumen or vessel breach could reliably assess IVC wall invasion with a sensitivity of 92.3% (95%-CI: 0.75-0.99) and a specificity of 86.4% (95%-CI: 0.65-0.97) (Fisher-test: p-value< 0.001). The positive predictive value (PPV) was 88.9% (95%-CI: 0.71-0.98) and the negative predictive value reached 90.5% (95%-CI: 0.70-0.99). There was an excellent interobserver agreement for determining IVC wall invasion with a kappa coefficient of 0.90 (95%CI: 0.79-1.00). CONCLUSIONS The present study indicates that standard preoperative MR imaging can be used to reliably assess IVC wall invasion, evaluating morphologic features such as the complete occlusion of the IVC lumen or vessel breach. Increases in IVC diameter are associated with a higher probability of IVC wall invasion.

Abstract
Intravascular tumor extension, also known as tumor thrombus, can occur in many different types of cancer. Those with the highest proclivity include Wilm's tumor, renal cell carcinoma (RCC), adrenal cortical carcinoma (ACC) and hepatocellular carcinoma (HCC). The presence of tumor thrombus markedly worsens prognosis and impacts treatment approach. Imaging plays a key role in its diagnosis. Endovascular methods also play a large role in treatment.

Abstract
Background: Renal cancer may invade the inferior vena cava (IVC) creating more complex surgical intervention. We investigate radiologic findings that may predict vascular reconstruction prior to surgery and future renal cancer-specific mortality. Materials and Methods: Radiologic findings included Mayo Clinic risk factors for vascular reconstruction: Right-sided tumor, anteroposterior diameter of the IVC at the ostium of the renal vein ≥24.0 mm, and radiologic identification of complete occlusion of the IVC. Additional factors included thrombus in the lumen of the hepatic veins and metastasis. Along with other demographic factors, analysis included Chi-squared analysis for vascular reconstruction and logistic regression for mortality. A Kaplan–Meier curve was created for the most significant radiologic factor. Results: Thirty-seven patients underwent IVC tumor thrombectomy at two institutions from April 2007 to February 2015. We found that Mayo risk factors of 0, 1, 2, and 3 and the proportions of vascular reconstruction of 0%, 0%, 12.5%, and 13.6%, respectively (P = 0.788). Hepatic vein involvement was the most significant determinate of renal cell carcinoma-specific mortality in multivariable analysis, controlling for the size of IVC at the hepatic veins, pulmonary metastasis, and Fuhrman grade (P = 0.02, Log-rank P = 0.002). Conclusion: Mayo risk factors did not predict vascular reconstruction in our small cohort of Level II–Level IV IVC thrombus undergoing IVC thrombectomy. Tumor thrombus traveling into the lumen of the hepatic veins was a significant risk factor for accelerated mortality.

Surgical technique for the treatment of renal cell carcinoma with inferior vena cava tumor thrombus: tips, tricks and oncological results. SPRINGERPLUS 2016; 5:132.

Abstract
Renal cell carcinoma represents 3 % of all cancers. Around 4–10 % of cases present with inferior vena cava involvement, generally with tumor thrombus. Clinical and preoperative stage will be classified depending of the thrombus extension. A high quality preoperative workup is essential to properly plan surgical approach. Complete surgical resection of the tumor is potentially the only curative treatment, although it supposes a real challenge due to operative difficulty, potential for massive bleeding or tumor pulmonary thromboembolism. Surgery includes techniques derived from transplantation surgery and, in some cases, cardiovascular intervention with cardiopulmonary bypass. Long-term oncological outcomes after complete removal of the entire tumor burden are acceptable. In this report we describe step-by-step surgical maneuvers depending on the thrombus lever, and focusing in complete abdominal approach for the complete excision of the tumor. Moreover, a recent literature review about oncological results is reported.
