The relationship between AIDS and cancer is an alarming and challenging aspect of modern medicine. Patients infected with HIV are not only subjected to a wide variety of opportunistic infections and neurologic manifestations, but also develop increasingly simultaneous or subsequent neoplastic diseases. This is the first book to confront this highly topical issue. It covers the most frequent tumor types, such as Kaposi's sarcoma, Hodgkin's as well as non-Hodgkin's lymphomas, anal cancer, and a variety of additional malignant tumors. The rapid rise in the number of HIV positive patients will be followed by an increasing demand for treatment facilitites for HIV-positive tumor patients. This volume thus aims to expose the epidemiologic and clinical implications of the topic and to awaken awareness among health professionals and authorities who must be prepared to deal with this growing problem.
