Langenhuijsen, Egbert Oosterwijk, Otto C. Boerman, Wim J.G. Oyen, Peter F.A. MuldersAbstractBased 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 regard...

Ablation, a minimally invasive tumour-destroying technique using focused radiation, is proving effective. So why is it not more widely known?Seven years ago, when Heather Hall was informed by her oncologist that her kidney cancer had spread to the liver, she initially assumed she had just months to live. “I’d been on chemotherapy for a while, but they’d done a CT scan and found three new tumours,” she says. “But they then said that, because the tumours were relatively small, they could try to lengthen my prognosis by removing them with ablation.”Hall underwent a course of microwave ablat...

ConclusionMeasurement of the size of metastatic lesions on the basis of axial DWI images are in close agreement with measurement based on conventional axial CT images, the most often employed approach in clinical trials today. The results in this pilot study can be used to estimate sufficient sample size in a larger trial with adequate power, were the results can be confirmed in a wider range of cancers other than renal cell carcinoma.

Conclusion: CT image of kidney cancer revealed the morphological and enhanced features of this tumor. The consistency between CT stage and pathological stage was high; thus, this method can be applied as a forecasting method for pathological staging.

Abstract Von Hippel-Landau (VHL) disease is characterized by malignant and benign tumors in multiple organs. Sunitinib, a tyrosine kinase inhibitor, has been clinically available for treating sporadic patients with recurrent or unresectable and metastatic clear renal cell carcinomas (cRCCs) and metastatic lesions of the lung, but its effect on VHL disease-associated tumors remains poorly understood. This retrospective case series examined the effect of sunitinib on RCC, hemangioblastomas, pheochromocytomas, and pancreatic neuroendocrine tumors in patients with confirmed VHL. Of note, three patients with VHL diseas...

Authors: Antoniou N, Karanastasis D Abstract Two cases are reported of patients with a single metastasis in the contralateral adrenal, one and nine years respectively after nephrectomy for localized cancer in the opposite kidney. These types of metastases are usually asymptomatic they do not appear with signs of adrenal insufficiency, they are detected incidentally and the diagnosis is confirmed mainly with CT scan, which comprises the method of choice for the detection of such types of metastases. Many adrenal metastases probably have been overlooked in the past when advanced imaging techniques were not available....

ConclusionCore needle biopsies of solid renal masses  ≤ 4 cm have excellent accuracy and may be used to select the correct treatment. Importantly, they may serve to prevent overtreatment of benign tumors.

In this study, the combination of these two imaging approaches is evaluated for detection and monitoring skeletal metastases in non-prostate GU cancers. Methods: Study patients with GU cancers with bone metastasis were enrolled on NCT02496208, a phase I treatment trial in metastatic GU cancers. All patients were male ranging in age from 20 - 77 years. Baseline studies involved 18F FDG PET/CT imaging followed immediately by 18F NaF PET/CT imaging the same day. Follow-up restaging studies were repeated with sequential imaging at 4-8 weeks after treatment in 7 patients. Bone lesions with focal uptake on either scan were manua...

Conclusions: These preliminary data suggest that measuring response of mRCC early after starting treatment using metabolic imaging criteria (PERCIST 1.0) may identify a sub-group of patients with a better outcome: PFS was not reached in the PMR group during the study period. Bone and soft tissue lesions in mRCC behaved similarly on metabolic imaging, whereas most bone lesions remained unchanged on anatomic imaging. While more data are needed to determine whether ceCT or PET/CT is the optimal imaging method for monitoring bone and soft tissue response in mRCC patients with bone metastases, our data suggest that both may be ...

385Objectives: Quantitative analysis using standardized uptake value (SUV) is commonly used in oncological PET imaging. Recently, a new Bayesian penalized-likelihood (PL) reconstruction algorithm has been developed to generate images with reduced noise and improved signal-to-noise ratio compared to conventional ordered subsets expectation maximization (OSEM) algorithm. However, it is not clear how the new PL reconstruction affects quantification of PET. The purpose of this study was to investigate the effect of the new Bayesian penalized-likelihood (PL) algorithm on quantitative parameters in Ga-68 DOTATOC PET for somatost...
