Background: The availability of high quality, clinically annotated patient samples is crucial for the study of biologic factors that influence the natural history of viral related malignancies, malignancies occurring in the setting of HIV, and Castleman disease Comprehensive genomic sequence of viral-associated malignancies, malignancies occurring in the setting of HIV, tumors hypothesized to be caused by endogenous retroviruses, and Castleman disease may identify diagnostic or prognostic disease signatures, and recurrent driver alterations that interact with viral factors, and may identify targets for new therapies Comparison of transcriptomes and genomes between cancers or Castleman disease from HIV+ and HIV- individuals might identify novel non-human sequences that could potentially suggest the presence of transcripts from hitherto undiscovered oncogenic viral agents Objective: -The primary objective of this protocol is to support molecular investigation of viral associated malignancies, malignancies occurring in the setting of HIV or other immunodeficiencies, and Castleman disease, by accrual of high quality, clinically annotated tissue from such patients as well as patients with tumors that may serve as appropriate controls. Eligibility: Age >18 years HIV or other acquired immunodeficiency and cancer or Viral-associated cancer or HIV-negative with cancer that commonly occurs in people with HIV or Kaposi sarcoma herpes virus (KSHV)-associated malignancy or related diseases, such as Multicentric Castleman Disease or Idiopathic Castleman disease or Tumors that are hypothesized to be caused by endogenous retroviruses Design: Samples will be processed using project specific collection and processing protocols. Collection of non-tumor specimens will generally be performed to obtain germ-line genetic material. The results between tumor and normal DNA will be analyzed to identify the somatic changes present in the cancer tissues. Alterations to be evaluated may include: detection of chromosomal changes, such as, but not limited to, amplification, deletions, loss of heterozygosity, translocations, etc.; as well as expression profiling and detection of transcripts resulting from translocations and mutations, including single nucleotide variants, insertions, deletions, etc. Multiple forms of project specific analyses may be performed, including evaluation of polymorphisms, mutations, gene expression and clinical pathologic correlation based on project specific statistical and bioinformatics plans. Alterations may also be analyzed within the context of biological pathways and systems biology being evaluated in a given project.
