Persons with HIV infection are at higher risk for developing lung cancer, independent of cigarette smoking, a new study found.
After adjusting for potentially confounding factors such as age, sex, and smoking status, the researchers found HIV infection was associated with a 3.6-fold increased risk for lung cancer compared to HIV-negative status.
"As HIV-infected persons survive longer, we are continuing to see that non-AIDS outcomes are becoming the primary causes of morbidity and mortality. Our study suggests that the risks for these non-AIDS outcomes may
be modulated by HIV infection," researchers said.
Further studies are planned to see if the biological effect of smoking is related to the degree of immune suppression or to antiretroviral treatment.
