  3. RMS-Mutation-Prediction-Expert-Annotations

    WARNING: After the release of v20, it was discovered that a mistake had been made during data conversion that affected the newly-released segmentations accompanying the "RMS-Mutation-Prediction" collection. Segmentations released in v20 for this collection have the segment labels for alveolar rhabdomyosarcoma (ARMS) and embryonal rhabdomyosarcoma (ERMS) switched in the metadata relative to the correct labels. Thus segment 3 in the released files is labelled in the metadata (the SegmentSequence) as ARMS but should correctly be interpreted as ERMS, and conversely segment 4 in the released files is labelled as ERMS but should be correctly interpreted as ARMS. We apologize for the mistake and any confusion that it has caused, and will be releasing a corrected version of the files in the next release as soon as possible. Collections analyzed:

New clinical metadata tables

v14 - May 2023

This release does not introduce any new data, but changes the bucket organization and introduces replication of IDC files in Amazon AWS storage buckets, as described in this section.

v13 - Mar 2023

New analysis results collection:

New clinical data collections:

v12 - Nov 2022

New collections:

Updated collections:

Other:

Metadata corresponding to "limited" access collections are removed.

New clinical data collections:

Other clinical data updates:

Limited access collections are removed. Clinical metadata for the COVID-19-NY-SUB and ACRIN 6698/I-SPY2 Breast DWI collections now includes information ingested from data dictionaries associated with these collections. In v11 the string value 'NA' was being changed to null during the ETL process for some columns/collections. This is now fixed in v12 and the value 'NA' is preserved.

v11 - Sept 2022

This release introduces clinical data ingested for a subset of collections, and now available via a dedicated BigQuery dataset.

New collections:

v10 - Aug 2022

In this release we introduce a new HTAN program including currently three collections release by the Human Tumor Atlas Network.

New collections:

Updated collections:

CPTAC, TCGA and NLST collections have been reconverted due to a technical issue identified with a subset of images included in v9.

  1. TCGA-DLBC

Note that the TCGA-KIRP and TCGA-BRCA collections (marked with the asterisk in the list above) are currently missing SM high resolution layer files/instances due to a known limitation of Google Healthcare that makes it not possible to ingest datasets that exceed some internal limits. Specifically, the following patient/studies are affected:

  • TCGA-KIRP: PatientID TCGA-5P-A9KA, StudyInstanceUID 2.25.191236165605958868867890945341011875563

  • TCGA-BRCA: PatientID TCGA-OL-A66H, StudyInstanceUID 2.25.82800314486527687800038836287574075736 The affected files will be included in IDC when the infrastructure limitation is addressed.

Collection access level change:

  1. Vestibular-Schwannoma-SEG is now available as public access collection

v9 - May 2022

This data release introduces the concept of differential license to IDC: some of the collections maintained by IDC contain items that have different licenses. As an example, radiology component of the TCGA-GBM collection is covered by the TCIA limited access license, and is not available in IDC, while the digital pathology component is covered by CC-BY. With this release, we complete sharing in full of the digital pathology component of the datasets released by the CPTAC and TCGA programs.

New collections:

Updated collections:

v8 - April 2022

The main highlight of this release is the addition of the NLST and TCGA Slide Microscopy imaging data. New TCGA content includes introduction of new (to IDC) TCGA collections that have only slide microscopy component, and addition of the slide microscopy component to those IDC collections that were available earlier and included only the radiology component.

New collections
