Using serial radiographic measurements, the magnitude of exponential increase in signature features deciphering tumor volume, invasion of tumor boundaries, or tumor spatial heterogeneity was associated with shorter overall survival. 2015 Jun;19(47):1-134. doi: 10.3310/hta19470. In the field of medicine, radiomics is a method that extracts a large number of features from radiographic medical images using data-characterisation algorithms. 2020 Jul 29;54(3):285-294. doi: 10.2478/raon-2020-0042. Harrell’s concordance index was 0.69 for CT and 0.66 for CBCT models for dataset 1. In the American Joint Committee on Cancer (AJCC) staging system of … Introduction: Radiomics extracts a large amount of quantitative information from medical images using specific data characterization algorithms.This information, called radiomic features, can be combined with clinical data … Two major treatment strategies employed in non-small cell lung cancer, NSCLC, are tyrosine kinase inhibitors, TKIs, and immune checkpoint inhibitors, ICIs. Data Availability Statement. The mean age was 53.1 ± 8.2 years. Keywords: Non-small cell lung cancer, Radiomics, CT, Random forest, Survival … Radiomics. Background and Purpose: In this study we investigated the interchangeability of planning CT and cone-beam CT (CBCT) extracted radiomic features. Comparison of Radiomic Feature Aggregation Methods for Patients with Multiple Tumors. Two CT radiomics features and a tumor volume doubling time (VDT) threshold … All the NSCLC patients in this data set were treated at Footnote. | Experimental design: The radiomics approach has the capacity to construct … Four independent NSCLC cohorts (total N = 446) were utilized for further validation of the radiomic signature. For these patients pretreatment CT scans, gene expression, and clinical … Radiomics signatures predicted tumor sensitivity to treatment in patients with NSCLC, offering an approach that could enhance clinical decision-making to continue systemic therapies and forecast overall survival. We aimed to explore radiologic phenotyping using a radiomics … The radiomics signatures predicted treatment sensitivity in the validation dataset of each study group with AUC (95 confidence interval): nivolumab, 0.77 (0.55-1.00); docetaxel, 0.67 (0.37-0.96); and gefitinib, 0.82 (0.53-0.97). Besides that, the potential added value of CT imaging … This collection contains images from 89 non-small cell lung cancer (NSCLC) patients that were treated with surgery. Material and Methods: One internal dataset of 132 and two external datasets of 62 and 94 stage I-IV NSCLC patients were included in this study. Sun S, Besson FL, Zhao B, Schwartz LH, Dercle L. Oncotarget. Material and Methods: One internal dataset of 132 and two external datasets of 62 and 94 stage I-IV N… Dercle L, Lu L, Schwartz LH, Qian M, Tejpar S, Eggleton P, Zhao B, Piessevaux H. J Natl Cancer Inst. Moreover, a previously developed radiomics signature has prognostic value for overall survival in three CBCT cohorts, showing the potential of CBCT radiomics to be used as prognostic imaging biomarker. eCollection 2020. NSCLC-Radiomics-Genomics. ... Radiomics is the extraction of data … Radiomics Feature Activation Maps as a New Tool for Signature Interpretability. eCollection 2020. 2020 Nov 9;15(11):e0241514. These features, termed radiomic features, have the potential to uncover disease characteristics that fail to be appreciated by the naked eye. Garau N, Paganelli C, Summers P, Choi W, Alam S, Lu W, Fanciullo C, Bellomi M, Baroni G, Rampinelli C. Med Phys. The choice of strategy is based on … doi: 10.1371/journal.pone.0241514. 89 patients. Radiomics Response Signature for Identification of Metastatic Colorectal Cancer Sensitive to Therapies Targeting EGFR Pathway. Started as a Capstone project for the BrainStation Data Science diploma program. PET/CT radiomics have also shown possibility to non-small cell lung cancer (NSCLC) treatment decisions. Furthermore, this study validates a previously described CT based prognostic radiomic signature for non-small cell lung cancer (NSCLC) patients using CBCT based features. 2020 Dec 22;11(51):4677-4680. doi: 10.18632/oncotarget.27847. Radiomics is the extraction of quantitative data from medical imaging, which has the potential to characterise tumour phenotype. Kaplan-Meier curves are based on model predictions of the radiomic signature. Radiomics research with NSCLC dataset from TCIA. © 2017 Computational Imaging & Bioinformatics Lab - Harvard Medical School Interchangeability was assessed by performing a linear regression on CT and CBCT extracted features. Growing evidence suggests that the efficacy of immunotherapy in non-small cell lung cancers (NSCLCs) is associated with the immune microenvironment within the tumor. Results: 13.3% (149 out of 1119) of the radiomic features, including all features of the previously published radiomic signature, showed an R2 above 0.85 between intermodal imaging techniques. PLoS One. Radiomics signatures predicted tumor sensitivity to treatment in patients with NSCLC, offering an approach that could enhance clinical decision-making to continue systemic therapies and forecast … Adenocarcinoma was 94% (32/34) of all cases, squamous cell carcinoma was 6% (2/34). Liu S, Liu S, Zhang C, Yu H, Liu X, Hu Y, Xu W, Tang X, Fu Q. For the radiomic signature, Kaplan-Meier curves were significantly different between groups with high and low prognostic value for both modalities. | Checkpoint blockade immunotherapy provides improved long-term survival in a subset of advanced stage non-small cell lung cancer (NSCLC) patients. ; 15 ( 11 ): e0241514 low-dose CT screening for early lung cancer M, chang,! ):1-134. doi: 10.1093/jnci/djaa017 field of medicine, radiomics is a method that a...
