Office of HIV and AIDS Malignancies (OHAM)

NCI’s Office of HIV and AIDS Malignancies (OHAM) is a great resource for learning about HIV-associated cancers.

Open versus Controlled-Access Data

OCG employs stringent human subjects’ protection and data access policies to protect the privacy and confidentiality of the research participants. Depending on the risk of patient identification, OCG programs data are available to the scientific community in two tiers: open or controlled-access. Both types of data can be accessed through its corresponding OCG program-specific data matrix or portal.

Open-access Data

Data within this category presents minimal risk of participant identification. Much of OCG program data, excluding patient identifiers, are open-access. OCG provides the scientific community the maximum amount of open-access data allowable under HIPAA guidelines. Access to these data does not require user certification, and researchers may explore data content without restriction.

Controlled-access Data

Data within this category present a higher risk of patient identification. While stripped of direct patient identifiers as defined by HIPAA, controlled-access data contain specific demographic, clinical, and genotypic information that are excluded in open-access data. Controlled-access data are unique and valuable to research projects for which open-access data are insufficient. Access to protected data requires user certification which can be obtained through NCBI’s dbGaP (National Center for Biotechnology Information’s database of Genotypes and Phenotypes).

Resources for Researchers

Resources for Researchers is a directory of NCI-supported tools and services for cancer researchers. Resources are developed and maintained by NCI scientists or were created with grant funding. Most resources are free and available to anyone. Each resource is owned by an NCI division, office, or center.
