Summary
Highly active combination antiretroviral therapy (cART) has decreased AIDS-defining cancers but increased non-AIDS-defining malignancies in Human Immunodeficiency Virus (HIV) patients. This shift requires new management strategies for HIV-associated cancers.
Area of Science:
- Oncology
- Infectious Diseases
- Epidemiology
Background:
- Human Immunodeficiency Virus (HIV) infection is strongly associated with various cancers.
- Historically, Kaposi sarcoma (KS) and non-Hodgkin's lymphoma (NHL) were prominent AIDS-defining malignancies.
- The advent of combination antiretroviral therapy (cART) has significantly altered cancer incidence in HIV-infected individuals.
Purpose of the Study:
- To review the changing landscape of Human Immunodeficiency Virus (HIV)-associated malignancies.
- To discuss the pathophysiology, epidemiology, and management of these cancers.
- To highlight the challenges posed by the increasing incidence of non-AIDS-defining malignancies.
Main Methods:
- Review of current literature on HIV-related malignancies.
- Analysis of epidemiological shifts in cancer incidence post-cART introduction.
- Examination of etiological factors including viral co-infections and treatment interactions.
Main Results:
- Significant decline in AIDS-defining malignancies (e.g., KS, NHL) due to cART.
- Noticeable increase in non-AIDS-defining malignancies (e.g., Hodgkin's lymphoma, lung, liver, anal cancers).
- Factors contributing to non-AIDS-defining cancers include longer life expectancy, toxic habits, viral co-infections (HBV, HCV, HPV), and cART interactions.
Conclusions:
- The management of cancer in HIV-infected patients is evolving due to changing malignancy patterns.
- Optimal treatment requires consideration of cART interactions with chemotherapy.
- Emerging non-AIDS-defining cancers present a new clinical challenge requiring tailored therapeutic approaches.

01:51Mechanisms of Retrovirus-induced Cancers
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

01:10Retrovirus Life Cycles
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...
01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
