Abstract
The AIDS Cancer and Specimen Resource (ACSR) supports scientific discovery in the area of HIV/AIDS-associated malignancies. The ACSR was established as a cooperative agreement between the NCI (Office of the Director, Division of Cancer Treatment and Diagnosis) and regional consortia, University of California, San Francisco (West Coast), George Washington University (East Coast) and Ohio State University (Mid-Region) to collect, preserve and disperse HIV-related tissues and biologic fluids and controls along with clinical data to qualified investigators. The available biological samples with clinical data and the application process are described on the ACSR web site. The ACSR tissue bank has more than 100,000 human HIV positive specimens that represent different processing (43), specimen (15), and anatomical site (50) types. The ACSR provides special biospecimen collections and prepares speciality items, e.g., tissue microarrays (TMA), DNA libraries. Requests have been greatest for Kaposi's sarcoma (32%) and non-Hodgkin's lymphoma (26%). Dispersed requests include 83% tissue (frozen and paraffin embedded), 18% plasma/serum and 9% other. ACSR also provides tissue microarrays of, e.g., Kaposi's sarcoma and non-Hodgkin's lymphoma, for biomarker assays and has developed collaborations with other groups that provide access to additional AIDS-related malignancy specimens. ACSR members and associates have completed 63 podium and poster presentations. Investigators have submitted 125 letters of intent requests. Discoveries using ACSR have been reported in 61 scientific publications in notable journals with an average impact factor of 7. The ACSR promotes the scientific exploration of the relationship between HIV/AIDS and malignancy by participation at national and international scientific meetings, contact with investigators who have productive research in this area and identifying, collecting, preserving, enhancing, and dispersing HIV/AIDS-related malignancy specimens to funded, approved researchers at no fee. Scientific discovery has been advanced by this unique biorepository. Investigators are encouraged to browse the ACSR Internet site for materials to enhance their own scientific initiatives.Entities:

* The impact factor of a journal varies by year. Each weighted impact factor is calculated by averaging the impact factor from the year of publication of each article.
# As impact factors are calculated from citations in a three year window following publication date, the last published impact factor is used for some more recent articles.
Figure 1Impact of ACSR Articles. Journals that published ACSR related articles are shown with the bubble size representing the number of articles (count shown inside bubble) while the width represents the weighted average impact factor. For example, Nature Medicine, which published two ACSR articles, is shown at far right because it has the highest impact factor, 28.010.

Potential uses of ACSR banked specimens
| Autopsies (multi-site) frozen & fixed | DNA and protein studies within individuals; involved vs. uninvolved tissues | |
| Tissue array analyses | Comparison of antigen expression between many patient tumors | |
| Diseased tissue specific cytokine, virus, antigen expression | ||
| Frozen lymphoma, KS and tumor tissues | DNA, RNA, and protein array studies; viral discovery/strain variation studies | |
| Non Hodgkin's lymphoma (AIDS & non-AIDS) epidemiology study (serum & fixed tissue) | Serologic studies on cases vs. controls for cytokine, viral antigen, serum proteins. Coupled with epidemiologic data in collaboration with Dr. Elizabeth Holly test disease associations, risk factors, transmission risk factors, resistance factors, lymphoma tissue, DNA/protein correlation with serum factors/disease associations. | |
| AIDS Malignancy Consortium clinical trial specimens | Longitudinal, trial associated specimens for analyses of disease specific markers in collaboration with AMC | |
| Serum specimens from cross-sectional survey in Thailand | Studies on low KS prevalence untreated HIV & serum cohort Infected vs. uninfected age & sex matched specimen comparisons | |
| Studies on HIV, non-US viral isolates. Repeat blood draws from HIV+ individuals available for rate of variation studies. | ||
