HIV-related malignancies pre- and post-highly active antiretroviral therapy: experiences in an inner city tertiary...

With highly active antiretroviral therapy (HAART), AIDS-defining malignancies are becoming less common. The outcomes with standard chemotherapy are improving. In the last 10 years there have been significant changes in our patient demographics due to immigration. The aim of this study was to review the demographics and outcomes of patients with cancer in the post-HAART era and to assess the impact of changing demographics and HAART through comparing them with previously published pre-HAART data from the same centre. A retrospective chart review of 42 patients diagnosed with malignancy from 2000 to 2007 was performed and compared with pre-HAART (1987-1994) data. The incidence of malignancies has decreased from 5.2% to 2.4%. The incidence of Kaposi's sarcoma and primary cerebral lymphoma has decreased. Non-Hodgkin's lymphoma incidence has remained stable, but survival has improved with 44% of patients achieving remission. Non-AIDS-defining malignancies have increased and were associated with longer duration of HIV infection. The change in patient demographics did not have an impact on the type of malignancies diagnosed. Overall the incidence of malignancy has decreased; however, the increase in non-AIDS-defining malignancies highlights the importance of early diagnosis, use of HAART and prospective surveillance.
