Langenhuijsen, Egbert Oosterwijk, Otto C. Boerman, Wim J.G. Oyen, Peter F.A. Mulders Based on the high expression of carbonic anhydrase IX (CAIX) in 95% of clear cell renal cell carcinoma (ccRCC), the anti-CAIX monoclonal antibody girentuximab can be used for the detection of ccRCC. This clinical study explores the value of 89Zr-labeled girentuximab positron emission tomography/computed tomography (PET/CT) imaging in diagnostic challenges regarding ccRCC. P...

Previous studies have reported that cases with clinical T1 (cT1) renal cell cancer (RCC) upstaging to pathological T3 is a risk factor to predicting postoperative recurrence after partial nephrectomy. The aim of our study was to investigate the impact of the morphological features of the enhanced computed tomography (CT) scan of cT1 renal cell cancer on predicting upstaging to pathological T3 or higher.

We present a very interesting case of RCC that had disseminated intraperitoneal and retroperitoneal cystic metastases that mimicked systemic hydatidosis. A detailed color Doppler sonography was followed by plain and contrast-enhanced computed tomography on a 64-slice multi-detector scanner. Imaging features were more in favor of right RCC with cystic lymph nodal metastasis. However, rare possibility of incidental hydatid disease with RCC could not be ruled out. Biopsy from left inguinal lymph nodes was taken, which confirmed metastatic deposits from RCC.

AbstractPurposeWe investigated prospectively whether18F-2-fluoro-2-deoxyglucose positron emission tomography/computed tomography (FDG PET/CT) can predict the overall survival (OS) of patients with advanced renal cell carcinoma (RCC) previously treated by molecular targeted therapies.MethodsBetween 2009 and 2016, 81 patients who had received single molecular targeted therapies (43 sorafenib, 27 sunitinib, 8 temsirolimus and others) and were scheduled for second line molecular targeted therapies for advanced RCC were enrolled in this prospective study. FDG PET/CT was performed after first line molecular targeted therapies, t...

Lenvatinib is an oral tyrosine kinase inhibitor of vascular endothelial growth factor receptors 1, 2, and 3, fibroblast growth factor receptors 1 through 4, as well as platelet-derived growth factor receptor α, RET, and KIT. At present, lenvatinib is used in the treatment of thyroid cancer and renal cell carcinoma. We herein report a case of a 67-year-old patient with squamous cell carcinoma of unknown primary who was effectively treated with lenvatinib. The patient was initially diagnosed as having un differentiated thyroid cancer, and after total thyroidectomy and bilateral lymph node dissection, lenvatinib was adm...

s M Abstract BACKGROUND: Computed tomography (CT) scans are being utilized to examine the influence of skeletal muscle and visceral adipose quantity and quality on health-related outcomes in clinical populations. However, little is known about the influence of contrast administration on these parameters. METHODS: Precontrast, arterial, and 3-minute postcontrast CT images of 45 patients with clear cell renal cell carcinoma were downloaded from The Cancer Imaging Archive and retrospectively analyzed for visceral adipose cross-sectional area (CSA) and density, and muscle CSA and density at the third lumbar verte...

Conclusions Preoperative simulation of selective ischemia was feasible and effective with HA3D reconstruction. In all the RAPN cases performed, selective clamping was successful, avoiding ischemia of the healthy renal remnant. A strict collaboration between urologists and bioengineers is mandatory to improve the technology. Patient summary In this report, we found that an accurate three-dimensional reconstruction of the kidney before conservative surgery for renal cancer seems to help in avoiding the global ischemia of the kidney. Further studies are needed to conclude if avoiding a percentage of ischemia to the kidney is ...

Conclusion In conclusion, it is important to identify this rare syndrome at early stages. Diagnosis for the patients with a positive family history for renal cell cancer and pneumothorax should be considered. FLCN sequencing should also be taken into account in patients and their families because incidence of renal cancer in BHD patients is very high and detection at early stages can prevent its metastasis.

Conclusion Incorporated 18-F FDG PET/CT is a very versatile and accurate imaging technique for renal cancers. It significantly improves the accuracy and predictive values over CT alone for detection of primary, recurrent and metastatic disease in renal cancer thus change the treatment decision.
