Article analysis:

The article "Radiomics as a personalized medicine tool in lung cancer: Separating the hope from the hype" provides a critical review of the current state of radiomics as a potential biomarker for personalized medicine in non-small cell lung cancer (NSCLC). The authors acknowledge that radiomics has gained popularity in recent years due to its ability to extract biological, prognostic, and predictive information from medical images that may not be visible upon visual inspection. However, they also highlight several technical limitations that hinder the translation of imaging biomarkers into clinical practice.

The article provides a detailed overview of the radiomic workflow, including image acquisition and reconstruction, segmentation, feature extraction, pre-processing steps, and data analysis. The authors note that repeatability and reproducibility are key requirements for the translation of imaging biomarkers into clinical practice but highlight several methodological limitations in CT-based radiomic analyses. They suggest solutions to these limitations and evaluate the current NSCLC radiomics literature to assess the risk associated with accepting published conclusions with respect to these limitations.

The authors also review different complementary scoring systems and initiatives that can be used to critically appraise data from radiomics studies. They provide boxplots showing the assessment of literature plotted against each other based on Radiomics Quality Score (RQS), Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD), and number of methodological limitations found in this review.

Overall, the article provides a balanced view of radiomics as a potential biomarker for personalized medicine in NSCLC. While acknowledging its potential benefits, it also highlights several technical limitations that need to be addressed before it can be translated into clinical practice. The authors provide suggestions for addressing these limitations and evaluating data from radiomics studies critically. However, they do not explore counterarguments or present both sides equally. Additionally, while they note possible risks associated with accepting published conclusions without considering limitations, they do not provide evidence for these claims.
