Project Summary

The TCGA-GBM data collection is part of a larger effort to enhance the TCGA data set with characterized radiological images.

Excerpt

The Cancer Imaging Program (CIP) with the cooperation of several of the TCGA tissue-contributing institutions has archived a large portion of the radiological images of the genetically-analyzed GBM cases.

Clinical, genetic, and pathological data resides in the TCGA data portal while the radiological data is stored within NBIA. on the Cancer Imaging Archive.   The data utilizes the same TCGA patient identifiers in both repositories, allowing researchers to explore the correlations between tissue genotype and radiological phenotype. Although the image archive has only acquired GBM cases at this point images from new TCGA-studied tumor types will be acquired and made available on the public NBIA archiveCancer Imaging Archive.

CIP TCGA-GBM Informatics Initiative

The Cancer Imaging Program has begun multiple projects to collaborate with the academic community to encourage cross disciplinary research which utilizes the data provided in these resources. More information about ongoing projects in this area can be found on the CIP TCGA Radiology Initiative wiki page.

caBIG Tools for TCGA-GBM Analysis

...

At present, the caBIG Imaging Workspace completed Phase I of this Enterprise Use-Case. ClearCanvas (Windows OS), Osirix (Mac) and XIP (caBIG open source/cross platform) were customized to allow retrieval of images from NBIA over the caGrid, markup by AIM standards, and storage back to an AIM-E Grid data service. More information can be found on the TCGA Radiology Project Phase I Homepage.
