DICOM converted Slide Microscopy images for the TCGA-TGCT collection

This dataset corresponds to a collection of images and/or image-derived data available from the National Cancer Institute Imaging Data Commons (IDC). This dataset was converted into DICOM representation and ingested by the IDC team. You can explore and visualize the corresponding images using the IDC Portal. You can use the manifests included in this Zenodo record to download the collection following the Download instructions below.

More than 90% of testicular cancer start in the germ cells, which are cells in the testicles and develop into sperm. This type of cancer is known as testicular germ cell cancer. Testicular germ cell cancer can be classified as either seminomas or nonseminomas, which may be identified by microscopy. Nonseminomas typically grow and spread more quickly than seminomas. A testicular germ cell tumor that contains a mix of both these subtypes is classified as a nonseminoma. TCGA studied both seminomas and nonseminomas.

Testicular germ cell cancer is rare, comprising 1-2% of all tumors in males. However, it is the most common cancer in men ages 15 to 35. The incidence of testicular germ cell cancer has been continuously rising in many countries, including Europe and the U.S. In 2013, about 8,000 American men were estimated to be diagnosed with the cancer. Of those, 370 are predicted to die from the disease. Men who are Caucasian, have an undescended testicle, abnormally developed testicles, or a family history of testicular cancer have a greater risk of developing testicular cancer. Fortunately, testicular germ cell cancer is highly treatable.

Files included

A manifest file's name indicates the IDC data release in which a version of collection data was first introduced. For example, tcga_tgct-idc_v22-aws.s5cmd corresponds to the contents of the tcga_tgct collection introduced in IDC data release v22.

• tcga_tgct-idc_v25-aws.s5cmd: AWS download manifest
• tcga_tgct-idc_v25-gcs.s5cmd: GCS download manifest
• tcga_tgct-idc_v25-dcf.dcf: DCF download manifest

Manifest files ending in -aws.s5cmd reference files in Amazon Web Services (AWS) buckets; -gcs.s5cmd reference files in Google Cloud Storage. The actual files are identical and mirrored between AWS and GCP.

Download instructions

Each manifest file includes instructions in its header on how to download the included files.

To download the files using .s5cmd manifests:

1. Install idc-index: pip install --upgrade idc-index
2. Download the files referenced by a manifest included in this dataset: idc download manifest.s5cmd

To download files using a .dcf manifest, see the manifest header.
