Abstract
INTRODUCTION: Human immunodeficiency virus (HIV)-infected individuals have a higher risk of some types of cancer. A chronic immunodeficiency state, increased survival in the highly active antiretroviral therapy (HAART) era and predisposition to certain oncogenic viral infections have been postulated as the main reasons. While, the incidence of acquired immunodeficiency syndrome (AIDS) defining cancers (ADCs) is declining in the post-HAART era, non-AIDS-defining cancers (NADCs) are becoming an important cause of mortality in these patients. MATERIALS AND METHODS: Analysis of the data of HIV-infected patients registered at an apex centre was done for 7 years. All patients were subjected to routine investigations on presentation (baseline) and during follow-up for the occurrence of any malignant disease. CD4 cell counts before starting anti-retroviral therapy and before the diagnosis of malignancy were noted. The date of the last review and the current status/outcome were recorded. RESULTS: Out of 1258, 17 patients were diagnosed with various malignancies. Seven patients (41.2%) had ADCs and the remaining 10 (58.8%) had NADCs. The mean duration between diagnosis of HIV infection and diagnosis of malignancy was 59.53 months. The mean survival duration from the diagnosis of malignancy for all cases was 21 months. The mean survival duration was 29 months and 15 months for ADC and NADC group respectively. CONCLUSIONS: NADCs are on the rise in the era of effective use of HAART and increasing life span of HIV patients. The index of suspicion for cancer should be higher in such patients, especially compared to opportunistic infections in view of good immunovirologic status.
