Abstract
Tumor thrombus, the intravascular extension of tumor into adjacent blood vessels, is frequently encountered in patients with renal cell carcinoma and hepatocellular carcinoma, and often involves the abdominal vasculature including the renal vein, portal vein, and the inferior vena cava. While a bland thrombus is composed of platelets and fibrin, in contrast, a tumor thrombus refers to an organized collection of tumor cells. Though oftentimes detected incidentally on imaging, tumor thrombus may have significant clinical implications and can be challenging to differentiate from bland thrombus. Additionally, the optimal management of tumor thrombus, including the use of anticoagulation, remains poorly described. This review summarizes common causes of tumor thrombus, as well as its impact on staging, prognosis, and treatment.

Abstract
Purpose: To explore the safety and effectiveness of the Pure Retroperitoneal Laparoscopic Peritoneum Incision Technique (PREP-IT) in laparoscopic radical nephrectomy (LRN) and inferior vena cave (IVC) tumor thrombectomy for right renal-cell carcinoma (RCC) with level Mayo I to III venous tumor thrombus (VTT). Patients and Methods: From May 2015 to September 2020, 92 patients with right RCC and Mayo I to III VTT were retrospectively reviewed, including 57 patients who underwent retroperitoneal LRN and IVC thrombectomy using PREP-IT, and 35 patients who underwent open surgery. PREP-IT refers to dissecting the retroperitoneum and temporarily placing the right kidney into the abdominal cavity to enlarge the retroperitoneal workspace for a safer and faster IVC operation. Results: Compared with the open surgery group, the PREP-IT group had a larger tumor diameter, while a larger proportion of Mayo I tumor thrombus and smaller maximum tumor thrombus width. Two patients (3.5%) in the PREP-IT group had a history of abdominal surgery. No conversion to open surgery or standard laparoscopic surgery occurred in PREP-IT group. Laparoscopic surgery with PREP-IT was characterized by shorter operative time, less surgical blood loss, shorter postoperative hospital stay, and lower postoperative complication rate. With a 33-month (ranges: 2-86) follow-up time period, the estimated mean overall survival time was 57.2 ± 5.3 and 58.1 ± 71.5 months in the PREP-IT group and open surgery group, respectively. Log-rank test indicated no significant difference between the two groups in terms of overall survival and cancer-specific survival. Conclusions: The PREP-IT is relatively safe and feasible for retroperitoneal LRN with right renal tumor and IVC tumor thrombus, allowing for a large workspace and wide exposure for IVC operations.

Int J Clin Oncol 2023; 28:145-154. [PMID: 36380158 DOI: 10.1007/s10147-022-02265-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Accepted: 11/02/2022] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To provide insight into the surgical and oncological outcomes of robotic, laparoscopic and open radical nephrectomy with venous thrombectomy (RALRN-VT, LRN-VT, ORN-VT) in patients with renal tumor and venous thrombus. MATERIALS AND METHODS A propensity-matched retrospective cohort study containing 324 patients with renal tumor and venous thrombus from January 2014 to August 2021 was analyzed. We compared surgical outcomes and we used the Kalan-Meier method to assess the overall survival (OS), tumor-specific survival (TSS), metastasis-free survival (MFS) and local recurrence-free survival (LRFS). The Pearson chi-square test and Fisher exact test, Wilcoxon rank sum test, Cox proportional hazards regression model and log-rank test were used. RESULTS After matching, baseline characteristics were comparable in the RALRN-VT, LRN-VT and ORN-VT group. The RALRN-VT group had the least operative time (median 134 min vs 289 min vs 330 min, P < 0.001), the least blood loss (median 250 ml vs 500 ml vs 1000 ml, P < 0.001) and the fewest packed red blood cells transfusion (median 400 ml vs 800 ml vs 1200 ml, P < 0.001). The ORN-VT group had the highest complication rate (18.2 vs 22.7 vs 43.2%, P = 0.005), the highest Clavien grade (P = 0.001) and the longest postoperative hospital stay (median 7d vs 8d vs 10d, P < 0.001). No significant difference in OS, TSS and MFS between the minimally invasive procedures (MIP, including RALRN-VT and LRN-VT) group and ORN-VT group was found. The hazard ratio of LRFS for the MIP group was 0.20 (95% CI 0.06-0.70, P = 0.01) compared with ORN-VT group. CONCLUSIONS RALRN-VT can result in the best surgical outcomes compared with LRN-VT and ORN-VT. The MIP group had a better LRFS compared with ORN-VT group.

Abstract
Abstract
Background
We aimed to compare the oncological outcomes between the oblique occlusion technique and the traditional technique for robot-assisted radical nephrectomy (RARN) with inferior vena cava (IVC) thrombectomy, and to explore the safety and effectiveness of the oblique occlusion technique.
Methods
Overall, 21 patients with renal cell carcinoma (RCC) and IVC tumor thrombus (TT) were admitted to our hospital from August 2019 to June 2020. All the patients underwent RARN with IVC thrombectomy, of which the IVC oblique occlusion technique was used in 11 patients and traditional occlusion technique was used in 10 patients. The oblique occlusion technique refers to oblique blocking from the upper corner of the right renal vein to the lower corner of the left renal vein using a vessel tourniquet or a vessel clamp (left RCC with IVCTT as an example).
Results
Compared with patients in the traditional group, those in the oblique group had lower serum creatinine at follow-up (3 month) (95 ± 21.1 vs. 131 ± 30.7 μmol/L, P = 0.03). There was no significant difference in operation time [149 (IQR 143–245) min vs. 148 (IQR 108–261) min, p = 0.86], IVC clamping time [18 (IQR 12–20) min vs. 20 (IQR 14–23) min, p = 0.41], and estimated intraoperative blood loss [300 (IQR 100–800) mL vs. 500 (IQR 175–738) mL, p = 0.51] between both groups. During a 16-month (range, 15–23 months) follow-up period, two cases progressed in the oblique group and three cases progressed in the traditional group.
Conclusions
The modified IVC oblique occlusion technique procedure is relatively safe and effective in RARN with IVC thrombectomy. The IVC oblique occlusion technique may play a role in the protection of renal function.

Abstract
Background To propose a quantitative model for predicting the surgical complexity of patients with renal cell carcinoma (RCC) and venous tumor thrombus (VTT). Method The clinical data of 226 cases of RCC with VTT in Peking University Third Hospital from January 2014 to August 2020 were retrospectively analyzed. Seven indicators were selected to establish the T.H.R.O.B.V.S. system, including alkaline phosphatase, tumor thrombus height, maximum tumor diameter, obesity, bland thrombus, vascular wall invasion, and side. Each indicator was assigned with 0, (1), and 2 points, and the total scores of 0~2, 3~5, and ≥6 were set as the low-, middle-, and high-risk groups, respectively. The surgical complexity was compared and validated among groups. Results As the risk increased, the proportion of open surgery significantly increased (P<0.001). The operation time (P<0.001), intraoperative blood loss (P<0.001), blood or plasma transfusion (P<0.001), and hospitalization (P<0.001) increased significantly. The postoperative complications (P<0.001), including notable complications (≥Clavein-Dindo II, P<0.001), were significantly different, and similar trends were shown in the validation group. Conclusion The T.H.R.O.B.V.S. scoring system is a quantifiable and satisfactory model to predict the surgical complexity and perioperative management of RCC with VTT.

Abstract
Background This study aims to report the surgical management, complications, and outcomes for patients with retroperitoneal tumor and venous thrombus. Methods We retrospectively analyzed 19 cases of retroperitoneal tumor with venous tumor thrombus from August 2015 to March 2021. A new tumor thrombus PUTH-RT grading system was proposed on the basis of the characteristics of the surgical techniques. Results Two cases of PUTH-RT-1a, two cases of PUTH-RT-1b, six cases of PUTH-RT-2, six cases of PUTH-RT-3, and three cases of PUTH-RT-4 were included. Surgeries were successfully performed in all 19 patients. Among them, five cases (26.3%) were operated via a completely laparoscopic approach and 13 cases (68.4%) via an open approach. One case (5.3%) was converted from laparoscopic to open approach. Five cases (26.3%) experienced postoperative complications. All patients were followed for a median of 14 months. Cancer-associated death occurred in three cases. Distant metastases occurred in seven cases. Conclusions We propose a new tumor thrombus grading system based on the anatomical characteristics of retroperitoneal tumors with venous tumor thrombus. Retroperitoneal tumor resection and removal of venous tumor thrombi are safe and effective for the treatment of such diseases.

Abstract
OBJECTIVES To investigate perioperative clinicopathological predictors and establish a predictive nomogram for survival in patients with renal cell carcinoma and venous tumor thrombus undergoing nephrectomy and thrombectomy. METHODS Patients with renal cell carcinoma and venous tumor thrombus undergoing nephrectomy and thrombectomy were included in the study between January 2014 and June 2020. Cox regression analysis was used for univariate and multivariate survival analyses. A predictive nomogram for survival was established and internally validated using bootstrap resampling method. RESULTS A total of 228 patients were enrolled in this study. The median age was 60 years (interquartile range 53-66 years), consisting of 174 (76.3%) males and 54 (23.7%) females. The median follow-up time was 17.5 months (range 1-74 months), 26.8% (61 of 228) patients died of all causes. In multivariable analysis, hemoglobin less than the lower limit of normal (hazard ratio 1.73; 95% confidence interval 1.01-2.96; P = 0.045), sarcomatoid feature (hazard ratio 3.67; 95% confidence interval 1.97-6.82; P < 0.001), perirenal fat invasion (hazard ratio 1.80; 95% confidence interval 1.05-3.09; P = 0.033), histological subtype (hazard ratio 2.74; 95% confidence interval 1.39-5.41; P = 0.004), and metastasis at surgery (hazard ratio 1.71; 95% confidence interval 1.01-2.90; P = 0.047) were independently associated with overall survival. The result of internal validation presented that the predictive performance of the nomogram for survival measured by C-index was 0.77. CONCLUSIONS We developed a predictive nomogram with well-internal validation for survival in patients with renal cell carcinoma and venous tumor thrombus, which can greatly promote risk stratification and treatment planning.

Abstract
Purpose To evaluate the long-term oncologic outcomes of renal cell carcinoma (RCC) patients with venous thrombus after radical nephrectomy and venous thrombectomy (RN-VT) and to determine the prognostic factors. Methods and Materials We reported our follow-up data of RCC patients with venous thrombus from January 2014 to September 2020. We used the Kaplan-Meier method to assess the overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS). The Cox proportional hazards regression model and competing risk model were used. Results After a median follow-up of 31 mon, eight-five patients (31.5%) died, and cancer-specific deaths occurred in 60 patients (22.2%). The 1 yr and 3 yr CSS were 89.3% and 72.7%, respectively. The median OS was 56.0 mon (95% CI 47.6-64.3 mon), and the 1 yr, 3 yr, and 5 yr OS were 87.0%, 62.1%, and 44.8%, respectively. For M1 patients, the median OS was 27.0 mon (95% CI 22.0-42.0 mon), and the 1 yr, 3 yr, and 5 yr OS were 78.0%, 41.5%, and 23.3%, respectively. For M0 patients, the median RFS was 38.0 mon (95% CI 32.5-43.5 mon), and the 1 yr and 3 yr RFS were 81.2% and 52.3%, respectively. Multivariate analyses showed that papillary RCC (HR 2.95, 95% CI 1.80-4.82, P < 0.001) or other RCC (HR 3.88, 95% CI 2.03-7.41, P < 0.001), perinephric fat invasion (HR 1.53, 95% CI 1.03-2.26, P = 0.04), sarcomatoid differentiation (HR 2.85, 95% CI 1.64-4.95, P < 0.001), Fuhrman grade 3 (HR 2.10, 95% CI 1.28-3.44, P = 0.003) or 4 (HR 3.55, 95% CI 2.09-6.03, P < 0.001), and distant metastasis (HR 1.76, 95% CI 1.18-2.63, P = 0.006) were associated with a worse CSS. Adjuvant therapy (HR 0.63, 95% CI 0.43-0.92, P = 0.02) was associated with a better CSS. Conclusions RCC patients can have an acceptable long-term survival after RN-VT. Prognostic factors influencing CSS included nonclear cell RCC histology, higher Fuhrman grade, sarcomatoid differentiation, perinephric fat invasion, distant metastasis, and adjuvant therapy.

Abstract
Purpose To explore the different treatment strategies for urinary tumors with Mayo IV thrombus. Materials and Methods We retrospectively analyzed the patients with Mayo IV thrombus in Peking University Third Hospital from January 2014 to April 2021. We used the Peking University Third Hospital (PUTH) grading system to classify urinary tumors with supradiaphragmatic thrombus. PUTH-A referred to the filled thrombus whose tip just reached above the diaphragm, or the thrombus entering the right atrium (< 2cm). PUTH-B referred to the filled thrombus entering the right atrium (> 2cm), or the thrombus invading the wall of the inferior pericardial vena cava. Detailed techniques were described for various scenarios. Clinicopathological data and perioperative outcomes were reported. Group difference statistical analysis was performed. Results A total of 26 cases of urinary tumors with supradiaphragmatic IVC thrombus (Mayo grade IV) underwent treatment were enrolled in this study. 19 patients in the PUTH-A group received the open approach without sternotomy and cardiopulmonary bypass. Seven patients in the PUTH-B group received open thoracotomy assisted by cardiopulmonary bypass. No intraoperative death occurred. After 56 months of follow-up, 46.2% (12 of 26) patients died of all causes. Estimated 1-year, 2-year, and 3-year overall survival were 72.0% (95% CI, 54.4%-89.6%), 58.2% (95% CI, 38.0%-78.4%), and 52.4% (95% CI, 31.2%-73.6%), respectively. Conclusions We introduced the PUTH grading system for the characteristics of urinary tumors with supradiaphragmatic tumor thrombus, and selected different surgical techniques according to different classifications. This grading system was relatively feasible and effective.

[PMID: 34963464 PMCID: PMC8713414 DOI: 10.1186/s12893-021-01448-0] [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: 04/12/2021] [Accepted: 12/20/2021] [Indexed: 11/10/2022] Open
Abstract
PURPOSE To explore the effect of tumor thrombus growing against the direction of venous return (GADVR) tumor thrombus on the choice of surgical approach, the impact on the complexity of the surgery and the prognosis. METHODS We retrospectively analyzed the clinicopathological data of 213 patients, who underwent surgery in a single center of Peking University Third Hospital between January 2016 and June 2020. For right renal cell carcinoma (RCC) and venous tumor thrombus (VTT), imaging revealed a filling defect in the left renal vein, which was significantly enhanced in enhanced imaging, suggesting that the tumor thrombus grew against the direction of venous return into the left renal vein. For left RCC and VTT, at least one of the left renal vein branches has tumor thrombus. The branches include the left adrenal vein, the left gonadal vein (testicular vein or ovarian vein), and the left ascending lumbar vein. The patients were divided into two groups according to whether they were GADVR tumor thrombus, and we compare the clinicopathological characteristics of GADVR tumor thrombus and non-GADVR tumor thrombus. Univariate and multivariate Cox regression analyses were performed to explore the risk factors that affect the prognosis of patients with RCC and VTT. Kaplan-Meier plots were conducted to evaluate the effect of GADVR on progression-free survival (PFS). RESULTS Compared with non-GADVR tumor thrombus, patients with GADVR tumor thrombus had a higher proportion of open surgery (76.2% vs. 52.1%, P = 0.035), a higher proportion of tumor thrombus adhering to the inferior vena cava (IVC) vessel wall (81% vs. 45.8%, P = 0.002), a higher proportion of segmental resection of the IVC vessel wall (61.9% vs. 15.6%, P < 0.001); higher preoperative serum creatinine value (110.0 μmol/L vs. 91.0 μmol/L, P = 0.015), a higher proportion of tumor thrombus combined with bland thrombus (non-tumor thrombus) (57.1% vs. 19.8%, P < 0.001). In terms of surgical complexity, patients with GADVR tumor thrombus had a longer median operation time (379 min vs. 308 min, P = 0.038), more median surgical blood loss (1400 mL vs. 600 mL, P = 0.018), and more postoperative complications (52.4% vs. 30.7%, P = 0.045). Multivariate Cox regression analysis showed that GADVR tumor thrombus, symptoms, postoperative serum creatinine, distant metastasis, sarcomatoid feature, pathological type, lymph node dissection were independent risk factors for PFS. Patients with GADVR tumor thrombus's median survival time was 14.0 months, while patients with non-GADVR tumor thrombus were 32.0 months (P = 0.016). GADVR tumor thrombus is an independent risk factor for PFS in patients with RCC and VTT. CONCLUSION GADVR tumor thrombus is a characteristic feature of tumor thrombus, with an incidence of 9.9%. It has a higher proportion of open surgery and higher surgical complexity, which is an independent risk factor for PFS.

The influence of venous tumor thrombus combined with bland thrombus on the surgical treatment and prognosis of renal cell carcinoma patients. Cancer Med 2020; 9:5860-5868. [PMID: 32627973 PMCID: PMC7433832 DOI: 10.1002/cam4.3264] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 06/08/2020] [Accepted: 06/09/2020] [Indexed: 11/23/2022] Open
Abstract
Objective To describe the clinical characteristics of renal cell carcinoma (RCC) with venous tumor thrombus (VTT) and bland thrombus (BT), and to evaluate the influence of BT on surgical treatment and cancer‐specific survival (CSS) of RCC with VTT. Methods We retrospectively reviewed clinical data of 123 patients with RCC and VTT, who underwent surgical treatment in our center between February 2015 and May 2018. Patients were divided into the BT group (21 patients) and non‐BT group (102 patients). Chi‐square and Mann‐Whitney U test were used for categorical and continuous variables respectively. Univariable log‐rank tests and multivariable Cox regressions were conducted to evaluate the prognostic significance of each variable. Kaplan‐Meier plots were performed to evaluate the influence of BT. Results In the delayed phase of enhanced magnetic resonance imaging (MRI), BT and VTT had difference. Patients were divided according to the relative position of BT: proximal end BT (one patients), contralateral renal vein BT (two patients), distal end BT (12 patients), and multiple BT (six patients). The average length of BT was 8.4 ± 5.8 cm (range: 0.6‐20.0 cm). Patients with BT had longer operative time (P = .001), more surgical blood loss (P = .004), higher proportion of open surgery (P = .006), more postoperative complications (P = .011). BT (hazard ratio [HR] = 3.323, P = .007) were independent risk factors for poor prognosis. Conclusions In the delayed phase of enhanced MRI, BT showed no obvious enhancement, while VTT usually showed enhancement. This was an important basis for preoperative imaging diagnosis of BT. The presence of BT increases the difficulty of surgery, and is correlated with adverse survival outcomes in patients with RCC and VTT.
