Summary


This collection contains images from 22 non-small cell lung cancer (NSCLC) patients. For each of these patients with pre-treatment hybrid PET-CT scans, repeated blinded manual delineations by 5 different radiation oncologist of the 3D volume of the gross tumor volume on CT and clinical outcome data are available. The above was repeated with the same set of 5 radiation oncologists, using an in-house autosegmentation tool for initial delineation followed by manual adjustment of the gross tumor volume outline. The delineations were cloned to coregistered PET and resampled in the grid spacing of the PET image.

This dataset refers to the Interobserver dataset of the study published in Nature Communications (http://doi.org/10.1038/ncomms5006). In short, the publicates used a radiomics approach to computed tomography data of 1,019 patients with lung or head-andneck cancer. Radiomics refers to the comprehensive quantification of tumor phenotypes by applying a large number of quantitative image features. In the published analysis, 440 features quantifying tumor image intensity, shape and texture, were extracted. We found that a large number of radiomic features have prognostic power in independent data sets, many of which were not identified as significant before. Radiogenomics analysis revealed that a prognostic radiomic signature, capturing intra-tumor heterogeneity, was associated with underlying geneexpression patterns. These data suggest that radiomics identities a general prognostic phenotype existing in both lung and head-and-neck cancer. This may have a clinical impact as imaging is routinely used in clinical practice, providing an unprecedented opportunity to improve decision-support in cancer treatment at low cost.

This dataset is intended to be open access to support repeatability and reproducibility of research in the radiomics domain. This dataset will be the subject of an upcoming Nature Data article addressing OPEN, FACT and FAIR radiomics practices to support transparency, harmonization and collaboration on radiomics.
