CGCI-HTMCP-CC: DICOM converted whole slide images from the Cancer Genome Characterization Initiative (CGCI) HIV+ Tumor Molecular Characterization Project (HTMCP) - Cervical Cancer

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.

The Office of Cancer Genomics at the National Cancer Institute sponsored a series of studies as part
of the Cancer Genome Characterization Initiative (CGCI) to assess novel emerging sequencing
technologies in cancer. The CGCI program included comprehensive characterization of the genetic
aberrations found in different pediatric and/or adult tumors.

As part of CGCI, the HIV+ Tumor Molecular Characterization Project (HTMCP) was a joint effort of the
Office of Cancer Genomics (OCG) and the Office of HIV and AIDS Malignancy (OHAM). Its goals were to
characterize HIV-associated cancers obtained from HIV-infected patients and compare them to the same
types of cancers from patients without HIV infection. Approximately 34.2 million people are living
with HIV worldwide. People infected with HIV have an elevated risk of cancer and mortality, and
cancer
is a ranking cause of death among people with HIV/AIDS. The Genome Sciences Center at the British
Columbia Cancer Agency performed whole genome sequencing of 100 cases of paired tumor and germline
DNA, along with transcriptome sequencing of HIV+ tumors.

Cervical cancer, a type of cancer that slowly forms in tissues of the cervix, is almost always
caused
by human papillomavirus (HPV) infection. In a thorough evaluation of various HPV-related
malignancies,
cervical cancer was selected for study based on its impact on mortality and on the prevalence of
high
quality source tissue.

This collection contains DICOM converted whole slide images from 211 of the 212 cases in the
GDC CGCI-HTMCP-CC project
(dbGaP accession
phs000528).
The proprietary format whole slide images were obtained from GDC and converted to DICOM Slide
Microscopy (SM) format using
idc-wsi-conversion. The 525 slides
include specimens stained with H&E (hematoxylin and eosin,
217 slides) and p16 immunohistochemistry (217 slides), along with additional IHC markers for subsets
of cases: BER-EP4 (15), MOC31 (15), P40 (15), P63 (15), CEA (5), ER (5), PR (5), Vimentin (5),
TP53 (5), CD56 (2), Chromogranin (2), and Synaptophysin (2).

Diagnoses coded in ICD-O-3 include squamous cell carcinoma, large cell, nonkeratinizing NOS (129
patients), squamous cell carcinoma, keratinizing NOS (48), adenocarcinoma NOS (19), small cell
carcinoma NOS (3), squamous cell carcinoma NOS (2), adenosquamous carcinoma (2), lymphoepithelial
carcinoma (2), and other rare subtypes.

Data organization: DICOM PatientIDs correspond to GDC case IDs and can be used to
link to genomic, transcriptomic, and clinical data in the
GDC portal. Of 212 GDC
cases, 211 have Tissue Slide images; the remaining case has no slide and is not represented
in this collection. Most patients have multiple slides representing different stains (H&E +
p16 as baseline, with additional IHC markers for subsets).

HTMCP-CC data is accessible at the NCI's Genomic Data Commons (GDC) via the
GDC Data Portal.

substudy data, including how to cite CGCI.
