Summary

The Cancer Genome Atlas-Glioblastoma Multiforme (TCGA-GBM) data collection is part of a larger effort to enhance the TCGA data set with characterized radiological images. 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 reside in the TCGA data portal, while the radiological data is stored on The Cancer Imaging Archive (TCIA). The data utilizes the same TCGA patient identifiers in both repositories, allowing researchers to explore the correlations between tissue genotype and radiological phenotype. This collection within TCIA is related to the GBM disease type within TCGA.

CIP TCGA Radiology Initiative

The CIP is supporting multiple projects within the academic community to encourage cross disciplinary research, which utilizes the data provided in these resources. Much more can be learned about this effort on the TCGA Glioma Phenotype Research Group page.

Related Data

The TCGA data portal has extensive clinical and genomic data, which can be matched to the patient identifiers of the images here in TCIA. Here is a snapshot of the data obtained from the data portal on 2/6/2014:

A Note about TCIA and TCGA Subject Identifiers and Dates

Subject Identifiers: a subject with radiology images stored in TCIA is identified with a Patient ID that is identical to the Patient ID of the same subject with demographic, clinical, pathological, and/or genomic data stored in TCGA. For each TCGA case, the baseline TCGA imaging studies found on TCIA are pre-surgical. 

Dates: TCIA and TCGA handle dates differently, and there are no immediate plans to reconcile:
