Pre-operative risk factors predicting missed diagnosis of renal vein tumor thrombus in renal cell carcinoma: a retrospective cohort study.

Pre-operative risk factors predicting missed diagnosis of renal vein tumor thrombus in renal cell carcinoma: a retrospective cohort study. Scand J Urol. 2020 Feb 14;:1-7 Authors: Jiang W, Cao C, Shi H, Shou J, Wang D, Wen L, Li C, Ma J Abstract PURPOSE: Previous reports showed that some patients with renal cell carcinoma (RCC) and renal vein tumor thrombus (RVTT) were misdiagnosed pre-operatively. To improve the accuracy of this diagnosis, the clinical characteristics of RCC with missed RVTT diagnosis were analyzed. METHODS: We retrospectively reviewed RCC patients with RVTT between January 2000 and December 2015. The survival analysis was estimated using the Kaplan-Meier method. The Cox proportional hazard models were applied to identify risk factors. RESULTS: The missed diagnosis rate of RVTT in RCC was 30.5%. In multivariate analysis, maximal tumor diameter, tumor located in the middle part, renal vein contrast agents filling insufficiently and tumor with collateral vessels (odds ratio = 1.22, 1.35, 1.25, 1.22; and p = .034, .003, .015 and .037, respectively) were independent predictors of missed RVTT diagnosis. A missed-diagnosis score was presented as area under curve of 0.852 (p

Conclusion: MRI staging of RCC is an accurate predictor of the surgical and pathological stage and has the potential to become a useful tool for preoperative identification of patients with RCC who can undergo NSS.

We present a case of positional compression of the left renal vein (LRV) after right nephrectomy and caval reconstruction, treated by external stenting using a reinforced vascular prosthesis. CASE REPORT: A 69-year-old female patient presented because of swelling of the left leg. A renal cell carcinoma (RCC) was visualized on computed tomography (CT) scan in the right kidney, with a thrombus occluding the inferior caval vein (ICV) and the right renal vein (RRV). A right nephrectomy was performed, with ligation of the already occluded ICV. Venotomy allowed thrombectomy of the ICV above the level of the renal veins. Veno...

Renal cell carcinoma accounts for more than 3% of all malignant diseases. Metastatic disease to the head and neck ranges from 15% to 30%. The 5-year survival rate after nephrectomy is 60% to 75%, but with multiorgan metastases the 5-year survival rate is significantly lower, 0% to 7%. The authors present the case of a patient with a progressive, painless right facial swelling over the maxillary area of 3-month's duration associated with a considerable decrease of right visual acuity. Cranial computed tomography scan and magnetic resonance imaging showed a maxillary sinus mass extending to the orbital cavity and 2 choroidal...

AbstractPurposeTo compare findings obtained with11C-choline and FDG PET/CT scanning for renal cell carcinoma staging and restaging.Materials and methodsTwenty-eight renal cell carcinoma patients whose histological subtype was clear cell type in 26 and papillary type in 2, while Fuhrman nuclear grade was G1,2 in 16 and G3,4 in 12, underwent both11C-choline and FDG PET/CT examinations before (n = 10) and/or after (n = 18) treatment, then those scanning modalities were compared in regard to patient- and lesion-based diagnostic performance using 5 grading scores. Final diagnosis in each case was obt...

We report a 65-year-old patient with an RCC with intravascular extension through renal vein into the IVC and right atrial combined with severe coronary artery disease. This case has not been described in the literature and there is no treatment guideline for it. Patient concerns: A 65-year-old patient was admitted to our clinic with complaints of edema of both lower extremities. Diagnoses: On the basis of the magnetic resonance imaging scan and coronary angiography, we strongly suspected an RCC with intravascular extension through renal vein into the IVC and right atrial combined with severe coronary artery disease. ...

We report a case of adult renal NB and summarize the clinical and imaging features of the reported cases. Patient concerns: A 41-year-old female was admitted to our hospital with a chief complaint of gross hematuria that had persisted for a month. Nonenhanced computed tomography (CT) revealed a hypodense right renal mass without calcification. Enhanced CT showed an infiltrative, heterogeneously enhancing right renal mass with retrocaval lymphadenopathy and right renal vein thrombus. Magnetic resonance imaging (MRI) revealed that the right renal mass was isointense relative to the renal parenchyma on nonenhanced T1-weigh...

Abstract Situs inversus, an uncommon mirror-image reversal of the major visceral and thoracic organs, is seldom of medical significance. However, the recognition of their unique anatomy is extremely important for those requiring surgical intervention. There are very few reported cases of renal cell carcinoma (RCC) developing in people with situs inversus. To our knowledge, this is the first reported case in Canada. A review of the literature only identified nine published cases worldwide. Here, we review and summarize pertinent information, including patient age and sex, size and location of tumour, method of surg...

Authors: Raoul JL, Adhoute X, Gilabert M, Edeline J Abstract Sorafenib is thus far the only systemic treatment for hepatocellular carcinoma (HCC) based on the results of two randomized controlled trials performed in Western and in Eastern countries, despite a poor response rate (from 2% to 3.3%) following conventional evaluation criteria. It is now recognized that the criteria (European Association of the Study of the Liver criteria, modified response evaluation criteria in solid tumors) based on contrast enhanced techniques (computed tomography scan, magnetic resonance imaging) aimed to assess the evolution of the...

Conclusions: Compared to the extension of RCC to the renal vein or IVC, extension of TCC to the renal vein or IVC is rare. TCC with a venous tumor thrombus is often misdiagnosed as RCC. However, a correct preoperative or intraoperative diagnosis is of great importance to decide surgical strategy. Laparoscopic radical nephroureterectomy with thrombectomy may be a safe and feasible operative method in treatment of TCC with a renal vein thrombus. The prognosis of such cases is poor even if chemotherapy and radiotherapy are scheduled.

This study evaluated the clinical outcome of patients with renal cell carcinoma (RCC) with tumour thrombus (TT) after surgical management. MATERIALS AND METHODS: In total, 142 consecutive RCC patients with TT who were operated on in Helsinki University Hospital between 2006 and 2014 were analysed. Eighty-eight (62%) of these patients had been operated on with radical intention and 54 (38%) with cytoreductive intention. A total of 73 patients (51%) received postoperative targeted therapy. The primary endpoint was cancer-specific survival (CSS). RESULTS: The 5 year CSS for level of involvement of TT in the renal...
