Trends and survival in AIDS-associated malignancies

Area of Science:

• Epidemiology
• Oncology
• Public Health

Background:

• AIDS-associated malignancies (AAM) are significant complications of HIV infection.
• Kaposi's sarcoma (KS) and non-Hodgkin lymphoma (NHL) are the most common AAMs.
• Understanding their epidemiology and temporal trends is crucial for patient management and public health strategies.

Purpose of the Study:

• To describe the epidemiology and temporal evolution of Kaposi's sarcoma (KS) and non-Hodgkin lymphoma (NHL) in AIDS patients.
• To analyze survival outcomes for KS and NHL.
• To identify potential biases in surveillance data for AAMs.

Main Methods:

• Analysis of data from 1569 AIDS cases reported to the AIDS Registry of Catalonia.
• Descriptive epidemiological analysis of KS and NHL incidence, demographics, and temporal trends.
• Survival analysis to determine prognosis for patients with KS and NHL.

Main Results:

• Of 1569 cases, 3.4% had NHL and 8.6% had KS.
• KS was more frequent in homosexual/bisexual men and at a higher age (38.22 years).
• NHL cases had the worst prognosis (median survival: 169 days), and KS prevalence decreased over time in intravenous drug users.

Conclusions:

• Non-Hodgkin lymphoma (NHL) presents a poor prognosis in AIDS patients and may become a leading cause of death.
• AIDS-associated malignancies (AAM) prevalence is expected to increase.
• Surveillance data require careful analysis to account for potential biases.
