<p>Evaluating Solid Lung Adenocarcinoma Anaplastic Lymphoma Kinase Gene Rearrangement Using Noninvasive Radiomics Biomarkers</p>

Abstract: To develop a radiogenomics classifier to assess anaplastic lymphoma kinase (ALK) gene rearrangement status in pretreated solid lung adenocarcinoma noninvasively. Materials and Methods: This study consisted of 140 consecutive pretreated solid lung adenocarcinoma patients with complete enhanced CT scans who were tested for both EGFR mutations and ALK status. Pre-contrast CT and standard post-contrast CT radiogenomics machine learning classifiers were designed as two separate classifiers. In each classifier, data… Show more

“…The linear kernel function was used as a kernel function of SVM. 30 The most important clinical factor was identified using the logistic regression with AIC. The clinical-radiomics nomogram was constructed incorporating the Combined Rad score and the most important clinical predictor using the "rms" package in R v.3.6.…”

“…In this context, radiomics and radiogenomics, may play a significant role thanks to the quantitative noninvasive and repeatable analysis of standard clinical imaging that encompasses the whole tumor volume, taking into account the hetMNA. Radiomics features may be associated with specific molecular pathways or mutations, offering reliable predictive tools for clinicians in breast cancer [20], glioma [14], lung cancer [15,21] and even in healthy tissue [22]. Furthermore, CT represent the most common modality used to diagnose and stage NB and for this reason the images are easily accessible even for retrospective analysis.…”

“…To date radiomics is mainly used in oncology to predict diagnosis, survival, progression of disease and gene mutation (i.e. radiogenomics) [12][13][14][15]. Since radiomics has the potential for predicting molecular characteristics, it can potentially be used for determination of mutational or amplification status of specific genes, as suggested by promising preliminary experiences also in the specific field.…”
