Project description:Recently, robot-assisted surgery has been widely used to treat several urological cancers. Robot-assisted radical nephrectomy (RARN) was approved by the health insurance system in April 2022; however, RARN with inferior vena cava tumor thrombectomy (IVCTT) is still challenging. Also, its safety and feasibility have not yet been established owing to lack of literature, especially in Japan. We performed RARN with IVCTT in four patients between April 2022 and March 2023 at Fujita Health University Hospital. To reduce the risk of tumor embolism and major hemorrhage, an "IVC-first, kidney-last" robotic technique was developed. The safety and feasibility of RARN with IVCTT were evaluated by assessing the perioperative outcomes. Three women and one man were enrolled in this study. The median age was 72 years, and the tumor was on the right side in all cases. According to the Mayo Clinic thrombus classification, two patients were classified as level I, and the others were classified as level II. The two patients at level I did not undergo presurgical treatments, whereas the others at level II underwent presurgical treatments, which were combinations of tyrosine kinase inhibitors and immune-checkpoint inhibitors. The median operation and console times were 341 and 247 min, respectively. The median bleeding volume was 577 mL, and no complications beyond grade III of the Clavien-Dindo classification were observed. The median length of postoperative hospital stay was 10 days. Although the sample size was relatively small, we demonstrated the safety and feasibility of RARN with IVCTT in the Japanese population.

Project description:BackgroundRenal cell carcinoma (RCC) is often locally invasive and may extend from the renal vein into the inferior vena cava (IVC) as a venous tumor thrombus (VTT). Radical nephrectomy with IVC tumor thrombectomy (IVC-TT) via an open approach has been shown to carry high morbidity and mortality. Recently, robot-associated radical nephrectomy (RARN) has been developed with the aim of improving the performance and outcomes of surgery for RCC with IVC-VTT.MethodsWe here present four patients who had right RCC with IVC-VTT and underwent RARN with IVC-TT in Nagasaki University Hospital. All four patients had level II IVC-TT and underwent RARN with IVC-TT using a da Vinci Xi surgical system. The procedure comprised performing the Kocher maneuver, exposing the right renal artery in the aortocaval region dorsal to the left renal vein, exposing, mobilizing, and clipping the IVC, clamping and incising the IVC, and removing the kidney with the VTT en bloc.ResultsThe mean tumor size was 83.1 (range, 50.1-115.2) mm and the mean length of the VTT within the IVC 41.6 (range, 25.3-44.3) mm. The mean console time was 290 (range, 287-367) minutes and the mean blood loss was 200 (range, 175-260) mL and no patient required blood transfusion.ConclusionsOur initial experience of the procedure of RARN with IVC-TT for level II IVC-VTT is that it is safe and has acceptable perioperative outcomes and complications.

Project description:BackgroundSurvival data regarding cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC) patients according to the type and extent of tumor-associated vascular thrombus are scarce.ObjectiveTo test for survival differences in mRCC patients treated with CN according to the type and extent of tumor-associated vascular thrombus.Design setting and participantsWithin Surveillance, Epidemiology, and End Results Research Plus (2004-2017), we identified CN mRCC patients with renal vein (pT3a-TT) versus infradiaphragmatic inferior vena cava (IVC; pT3b) versus supradiaphragmatic IVC tumor thrombus/IVC invasion (pT3c).Outcome measurements and statistical analysisOverall survival (OS) was addressed in Kaplan-Meier and Cox regression analyses, in addition to 3-mo landmark analyses.Results and limitationsOf 2170 mRCC patients, 1880 (87%), 204 (9%), and 86 (4%) harbored pT3a-TT, pT3b, and pT3c, respectively. The respective median OS periods were 21, 23, and 12 mo (p < 0.001). In multivariable Cox regression models, pT3c stage, but not pT3b stage, was an independent predictor of higher overall mortality (hazard ratio [HR]: 1.37; 95% confidence interval [CI]: 1.09-1.73; p = 0.007), as well as in 6-mo landmark analyses (HR: 1.36; 95% CI: 1.02-1.80; p = 0.04). In the sensitivity analysis, relying on all pT3a patients, the predictor status of pT3c stage remained unchanged (HR: 1.37; 95% CI: 1.09-1.71; p = 0.007). Limitations have to be addressed regarding the sample size and the retrospective design of the current study.ConclusionsAlthough overall mortality is significantly higher in pT3c mRCC patients than in their pT3b and pT3a-TT counterparts, these individuals may still expect 12-mo or better OS after CN versus virtually 2-yr OS in their pT3a and pT3b counterparts.Patient summaryIn this study, we looked at the survival outcomes of metastatic renal cell carcinoma patients who presented with tumor thrombus at cytoreductive nephrectomy. Even though these patients with most advanced tumor thrombus stage demonstrated lower survival rates, the median overall survival was still 1 yr.

Project description:PurposeOpen radical nephrectomy with inferior vena cava thrombectomy (O-CT) is standard management for renal cell carcinoma with inferior vena cava thrombus. First reported a decade ago, robotic-assisted radical nephrectomy with inferior vena cava thrombectomy (R-CT) is a minimally invasive option for this disease. We aimed to perform a systematic review to assess the safety and feasibility of R-CT in terms of perioperative outcomes and compare the outcomes between R-CT and O-CT.Materials and methodsThe PubMed®, Scopus®, Cochrane Central Register of Controlled Trials and Web of ScienceTM databases were searched using the free-text and MeSH terms "renal cell carcinoma," "inferior vena cava," "thrombosis" or "thrombus," "robot" and "thrombectomy." Studies reporting perioperative outcomes of R-CT and studies comparing R-CT with O-CT were included. The review was done in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines.ResultsThe search retrieved 28 articles describing R-CT, including 7 comparative studies. This systematic review included 1,375 patients, out of which 329 patients were in single-arm studies and 1,046 patients were in comparative studies. Of the 329 patients who underwent R-CT, 14.7% were level I, 60.9% level II, 20.4% level III and 2.5% level IV thrombus. Operative time ranged from 150 to 530 minutes; blood transfusion was administered in 38.2% (126). The overall complication rate was 30.3% (99). R-CT, in comparison to O-CT, was associated with a lower blood transfusion rate (18.4% vs 64.3%, p=0.002) and a lower complication rate (14.5% vs 36.7%, p=0.005). Major complication and 30-day mortality rates were similar in both groups.ConclusionsR-CT has acceptable perioperative outcomes in carefully selected patients. Compared with O-CT, R-CT is associated with a lower blood transfusion rate and fewer overall complications. In experienced hands with carefully selected patients, R-CT is feasible and safe, with acceptable outcomes; however, selection bias limits definitive inference of these results, and optimal patient selection criteria remain to be described.

Project description:BackgroundRadical nephrectomy with inferior vena cava thrombectomy (RN-IVCT) is a complicated procedure for which the impact of hospital case volume on overall survival (OS) is unknown.ObjectiveTo assess the degree to which renal cell carcinoma (RCC) with inferior vena cava tumor thrombus (IVC-TT) care is centralized and to evaluate the impact of hospital case volume on outcomes following RN-IVCT.Design, setting, and participantsThe National Cancer Data Base was queried for patients with pT3b-c RCC treated with RN-IVCT. Hospitals were classified by case volume percentile as low (<75th percentile, <0.67 cases annually), intermediate (75th-95th percentile, 0.67-2.99 cases annually), or high (>95th percentile, >3 cases annually).Outcome measurements and statistical analysisThe primary outcome was OS. Secondary outcomes were short-term (30- and 90-d) mortality rates according to hospital case volume. Kaplan-Meier curves and Cox regression model were used to evaluate OS and the effect of covariables.Results and limitationsThere were 2664 cases of RN-IVCT for pT3b-c tumors reported by 573 institutions, of which 435, 108, and 30 were classified as low, intermediate, and high volume, accounting for 28.5%, 34.5%, and 37% of cases, respectively. Treatment at high-volume institutions was associated with better OS: the median OS was 42, 53, and 60 months for low, intermediate and high-volume centers, respectively (p=0.009). After multivariable adjustment, treatment at a high-volume institution was associated with a 24% relative risk reduction for all-cause mortality compared to treatment at a low-volume institution (hazard ratio 0.76, 95% confidence interval 0.65-0.89; p=0.001). There was no significant difference in short-term mortality following RN-IVCT when stratified by hospital case volume.ConclusionsHigher hospital case volume was associated with longer OS for patients undergoing RN-IVCT. These findings support efforts to centralize care for cases of advanced RCC.Patient summaryIn this study we looked at the impact of hospital case volume on survival following surgery for renal cell carcinoma and inferior vena cava thrombectomy. Survival was significantly better in high-volume hospitals performing three or more procedures per year.

Project description:BackgroundInferior vena cava thrombosis is a rare blunt abdominal trauma complication often associated with severe liver injury. We present two cases of inferior vena cava thrombosis due to mild liver injuries.Case presentationCase 1 was a 25-year-old woman taking oral contraceptives for dysmenorrhea who was injured in a motorcycle accident. Contrast-enhanced computed tomography revealed hepatic contusion of the sixth segment. At 1 week after the accident, inferior vena cava thrombosis was detected. Case 2 was a 58-year-old man injured in a motorcycle accident. Contrast-enhanced computed tomography showed traumatic subarachnoid hemorrhage, right hemothorax, and liver injury with hepatic contusion of the sixth segment. At 1 week after the accident, inferior vena cava thrombosis was observed.ConclusionInferior vena cava thrombosis can occur following liver injury, regardless of damage severity. When there are thrombogenic factors and damage near the inferior vena cava, follow-up examinations should be carried out.

Project description:BackgroundRobot-assisted surgery is widely performed for renal cell carcinoma (RCC) with inferior vena cava (IVC) tumor thrombi. Although many chemotherapeutic options are available for the treatment of unresectable RCC, there are very few reports on robot-assisted radical nephrectomy (RARN) with inferior vena cava thrombectomy (IVCT) after presurgical treatment with immune checkpoint inhibitors and tyrosine kinase inhibitors. We believe that pre-surgical treatment can provide minimally invasive surgical benefits to high-risk patients during the perioperative period.Case descriptionA 77-year-old male with right RCC that invaded the IVC (cT3bN0M0, Mayo classification level III) underwent pembrolizumab and axitinib combination therapy because he had high surgical risk due to angina pectoris. The level of the tumor thrombus decreased from level III to II, and RARN with IVCT was then performed. Surgery was performed without complications, and the patient was discharged on postoperative day seven. The pathological diagnosis was clear cell RCC (ypT3b, G2). Adjuvant chemotherapy using pembrolizumab monotherapy is still ongoing.ConclusionsIn this report, the inferior vena cave tumor thrombus level was down staged from level III to level II by treatment with pembrolizumab and axitinib. RARN with IVCT was safely performed without complication completely under robotic assistance.

Project description:Surgical management of renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombus is inherently complex, posing challenges for even the most experienced urologists. Until the mid-2000s, nephrectomy with IVC thrombectomy was exclusively performed using variations of the open technique initially described decades earlier, but since then several institutions have reported their robotic experiences. Robotic IVC thrombectomy was initially reported for level I and II thrombi, and more recently in higher-lever III thrombi. In general, the robotic approach is associated with less blood loss and shorter hospital stays compared to the open approach, low rates of open conversion in reported cases, relatively low rates of high-grade complications, and favorable overall survival on short-term follow-up in limited cohorts. Operative times are longer, costs are significantly higher, and left-sided tumors always require intraoperative repositioning and usually require preoperative embolization. To date, criteria for patient selection or open conversion have not been defined, and long-term oncologic outcomes are lacking. While the early published robotic experience demonstrates feasibility and safety in carefully selected patients, longer-term follow-up remains necessary. Patient selection, indications for open conversion, logistics of conversion particularly in emergent settings, necessity and safety of preoperative embolization, the value proposition, and long-term oncologic outcomes must all be clearly defined before this approach is widely adopted.
