Abstract:
Aside from opportunistic infections, several neoplasms have been identified as part of the spectrum of acquired immunodeficiency syndrome (AIDS) as defined by the Centers for Disease Control. Kaposi's sarcoma (KS) was the first such neoplasm to be recognized within the spectrum of AIDS. Although the classic form of Kaposi's sarcoma had been well recognized prior to the epidemic of AIDS, it was quite distinct from the illness that was seen in its epidemic form in young homosexual males. In this setting, Kaposi's sarcoma is an aggressive disease, with extensive involvement of skin and mucous membranes, early dissemination to lymph nodes, impressive development of extreme lymphedema, even in the absence of bulky adenopathy, and rapid spread to visceral organs, including lungs and gastrointestinal tract, among others. Although rapid clinical progression and short median survival have been the rule, a spectrum of disease has been seen such that some patients have survived for many years with disease limited to the skin. Certain clinical and laboratory features, such as presence of unexplained fever, night sweats, weight loss (B symptoms), or significant T-4-lymphocytopenia, have been identified as indicators of poor prognosis. Various therapeutic interventions have been employed in epidemic KS, and although partial and complete remissions have occurred, no regimen yet reported has significantly improved the survival of treated patients. High-dose recombinant alpha interferon has produced response rates in approximately 30% of treated patients, although toxicity has been observed in approximately 30% as well. Likewise, vinblastine has produced similar response rates with no evidence of long-term efficacy or cure. Aside from Kaposi's sarcoma, lymphoma primary to the central nervous system was recognized early in the AIDS epidemic as a criterion for inclusion within AIDS in patients less than sixty years of age. Several years after the initial reports of disease, it became apparent that specific types of systemic lymphoma were also quite extraordinary, and the definition of AIDS was amended in June 1985 to include high-grade B-cell lymphomas in individuals who had positive serology or virology for the human immunodeficiency virus (HIV). The AIDS-related lymphomas are characteristic, both pathologically and clinically. The vast majority of these cases have been high-grade B-lymphoid tumors of either immunoblastic or small-non-cleaved type (also known as undifferentiated, Burkitt, or Burkitt-like).(ABSTRACT TRUNCATED AT 400 WORDS)
