title: Malignancy in HIV/AIDs: a single hospital experience.
abstract: OBJECTIVE
  Our hospital serves an area with a significant number of patients seropositive for the human immunodeficiency virus (HIV). Intravenous drug abuse and heterosexual exposure are by far the predominant risk factors for HIV and acquired immunodeficiency syndrome (AIDS). Seven percent of these patients develop malignancies. Our aim was to study the types of tumor, their distribution, and to evaluate the patients' outcome.
  
  
  METHODS
  Of 3,578 patients with HIV infection or AIDS treated between 1993 and 1998, 245 had 1 or more malignancies. Information was collected on age, sex, race, predisposing risk factors for AIDS, malignancies, symptoms at presentation, the time of the onset of AIDS, CD4 cell counts, pathology findings, and mortality.
  
  
  RESULTS
  Although aspects of our patients resembled those of previously studied groups of patients with AIDS, there also were ways in which our patients differed from those other groups. Of our patients, 21. 6% had non-AIDS-defining (NAD) invasive malignancies. This was considerably higher than the rate in most studies. Twenty-seven patients with such malignancies died during the study. Forty-two other patients had pre-invasive cancers. Among patients having AIDS-defining (AD) malignancies, 55.9% died, a fact that was related to patients' low CD4 cell counts and late presentation. Our 97 patients with Kaposi sarcoma included 22 women, a relatively high number that may be related to the fact that most of our patients were intravenous drug abusers or had become infected by heterosexual transmission of HIV.
  
  
  CONCLUSIONS
  AIDS is associated with a high risk of malignancy and an unusual spectrum of tumors. Patients with invasive tumors have advanced disease at the time of initial presentation. Those with AD tumors have a worse prognosis than patients with NAD tumors. The impact of highly active antiretroviral therapy on both AD and NAD tumors needs to be further evaluated.
