Human Papillomavirus-Associated Cancers in Patients With Human Immunodeficiency Virus Infection and Acquired Immunodeficiency Syndrome

TL;DR: HPV-associated malignancies occur at increased rates in persons with HIV/AIDS, and increasing RRs for in situ cancers to and beyond the time of AIDS onset may reflect the gradual loss of control over HPV-infected keratinocytes with advancing immunosuppression.
Journal ArticleDOI

Association of cancer with AIDS-related immunosuppression in adults.

TL;DR: Although occurring in overall excess, most non-AIDS-defining cancers do not appear to be influenced by the advancing immunosuppression associated with HIV disease progression.
Journal ArticleDOI

Trends in cancer risk among people with AIDS in the United States 1980-2002.

TL;DR: Dramatic declines in KS and NHL were temporally related to improving therapies, especially introduction of HAART, but those with AIDS remain at marked risk of cancer.
Journal ArticleDOI

Cancer risk in people infected with human immunodeficiency virus in the United States

TL;DR: It is concluded that KS and NHL incidence declined markedly in recent years, likely reflecting HAART‐related improvements in immunity, while incidence of some non‐AIDS‐defining cancers increased, leading to a shift in the spectrum of cancer among HIV‐infected persons.
