Radiogenomics in Clear Cell Renal Cell Carcinoma: A Review of the Current Status and Future Directions

Radiogenomics is a field of translational radiology that aims to associate a disease’s radiologic phenotype with its underlying genotype, thus offering a novel class of non-invasive biomarkers with diagnostic, prognostic, and therapeutic potential. We herein review current radiogenomics literature in clear cell renal cell carcinoma (ccRCC), the most common renal malignancy. A literature review was performed by querying PubMed, Medline, Cochrane Library, Google Scholar, and Web of Science databases, identifying all relevant articles using the following search terms: “radiogenomics”, “renal cell carcinoma”, and “clear cell renal cell carcinoma”. Articles included were limited to the English language and published between 2009–2021. Of 141 retrieved articles, 16 fit our inclusion criteria. Most studies used computed tomography (CT) images from open-source and institutional databases to extract radiomic features that were then modeled against common genomic mutations in ccRCC using a variety of machine learning algorithms. In more recent studies, we noted a shift towards the prediction of transcriptomic and/or epigenetic disease profiles, as well as downstream clinical outcomes. Radiogenomics offers a platform for the development of non-invasive biomarkers for ccRCC, with promising results in small-scale retrospective studies. However, more research is needed to identify and validate robust radiogenomic biomarkers before integration into clinical practice

For Better or For Worse? State-Level Marital Formation and Risk Sharing

Why do some U.S. states have higher levels of marital formation than others? This paper introduces an economic model wherein a state’s representative individual may choose to marry in order to diversify his or her idiosyncratic income risk. The paper demonstrates that such a diversification motive is enhanced for some utility functions when a state’s level of undiversifiable risk becomes larger, and when a state’s initial income is lower. A test of the model’s predictions, using cross-sectional data for the 50 U.S. states, provides some suggestive evidence for a risk sharing motive in marriage formation and joint spouse labor participation.
