BACKGROUND & AIMS: People infected with human immunodeficiency virus (HIV) have an
increased risk of some malignancies, but little is known about the effects of infection on risk
of cancers of the upper gastrointestinal tract. We evaluated the risks of different histologic
and anatomic subtypes of carcinomas and non-Hodgkin lymphomas (NHLs) of the stomach
and esophagus in people with acquired immunodeficiency syndrome (AIDS). METHODS:

BACKGROUND & AIMS
People infected with human immunodeficiency virus (HIV) have an increased risk of some malignancies, but little is known about the effects of infection on risk of cancers of the upper gastrointestinal tract. We evaluated the risks of different histologic and anatomic subtypes of carcinomas and non-Hodgkin lymphomas (NHLs) of the stomach and esophagus in people with acquired immunodeficiency syndrome (AIDS).
METHODS
We analyzed data from the HIV/AIDS Cancer Match Study, which links data collected from 1980 to 2007 for 16 US population-based HIV and AIDS and cancer registries. We compared risks of stomach and esophageal malignancies in people with AIDS (N = 596,955) with those of the general population using standardized incidence ratios (SIRs). We assessed calendar trends using Poisson regression.
RESULTS
People with AIDS had increased risks of carcinomas of the esophagus (SIR, 1.69; 95% confidence interval [CI], 1.37–2.07; n = 95) and stomach (SIR, 1.44; 95% CI, 1.17–1.76; n = 96). Risk was increased for esophageal adenocarcinoma (SIR, 1.91; 95% CI, 1.31–2.70) and squamous cell carcinoma (SIR, 1.47; 95% CI, 1.10–1.92). People with AIDS had greater risks of carcinomas of the gastric cardia (SIR, 1.36; 95% CI, 0.83–2.11) and noncardia (SIR, 1.53; 95% CI, 1.12–2.05) than the general population. Although most stomach and esophageal NHLs that developed in people with AIDS were diffuse large B-cell lymphomas, these individuals also had an increased risk of stomach mucosa–associated lymphoid tissue lymphoma (SIR, 5.99; 95% CI, 3.19–10.2; n = 13). The incidence of carcinomas remained fairly constant over time, but rates of NHL decreased from 1980 to 2007 (Ptrend < .0001).
CONCLUSIONS
People with AIDS are at increased risk for developing esophageal and stomach carcinomas and NHLs. Although the incidence of NHL decreased from 1980 to 2007 as treatments for HIV infection improved, HIV-infected individuals face continued risks of esophageal and stomach carcinomas.
