HTAN Clinical Data

HTAN clinical data consists of three tiers.

Tier 1 is based on the NCI Genomic Data Commons (GDC) clinical data model, while Tiers 2 and 3 are extensions to the GDC model.

TierDescription
1Seven categories of clinical data, based on the GDC clinical data model. See GDC Table below.
2HTAN disease-agnostic extensions to the GDC clinical data model.
3HTAN disease-specific extensions to the GDC clinical data model.

Tier 1 Clinical Data

Tier 1 clinical data consists of seven categories of data from the GDC Data Model.

CategoryDescription
DemographicsData for the characterization of the patient by means of segmenting the population (e.g., characterization by age, sex, or race).
DiagnosisData from the investigation, analysis and recognition of the presence and nature of disease, condition, or injury from expressed signs and symptoms; also, the scientific determination of any kind; the concise results of such an investigation.
ExposureClinically relevant patient information not immediately resulting from genetic predispositions.
Family HistoryRecord of a patient's background regarding cancer events of blood relatives.
Follow-upA visit by a patient or study participant to a medical professional. A clinical encounter that encompasses planned and unplanned trial interventions, procedures and assessments that may be performed on a subject. A visit has a start and an end, each described with a rule. The process by which information about the health status of an individual is obtained before and after a study has officially closed; an activity that continues something that has already begun or that repeats something that has already been done.
Molecular TestInformation pertaining to any molecular tests performed on the patient during a clinical event.
TherapyRecord of the administration and intention of therapeutic agents provided to a patient to alter the course of a pathologic process.

Tiers 2 and 3 Clinical Data

Tier 2 consists of disease-agnostic extensions to the GDC clinical data model.

Tier 3 consists of disease-specific extensions to the GDC clinical data model. This covers additional elements for Acute Lymphoblastic Leukemia (ALL), Brain Cancer, Breast Cancer, Lung Cancer, Melanoma, Ovarian Cancer, Pancreatic Cancer, Prostate Cancer and Sarcoma.
