Patients with HIV and AIDS are at increased risk for some malignancies. To determine if patients with AIDS have higher rates of stomach cancer, esophageal cancer, or lymphoma compared with the general population, investigators examined data from 1980 to 2007 for 596,955 patients with AIDS from a linked dataset of 16 U.S. population-based AIDS registries and corresponding cancer registries.
Compared with the general population, patients with AIDS had a higher incidence of both esophageal cancer (standardized incidence ratio, 1.69; 95% confidence interval, 1.37–2.07) and gastric cancer (SIR, 1.44; 95% CI, 1.17–1.76). The number of cases was small (esophageal cancer, 95; stomach cancer, 96). For esophageal cancers, incidence of both adenocarcin…
