We agree with Dr. Diamond that systematic X-ray screening is not associated with a decrease in mortality from lung carcinoma in smokers who are negative for the human immunodeficiency virus (HIV).1

However, our proposal was based on the fact that lung carcinoma appears to have a higher incidence, a more aggressive nature, and a delayed diagnosis and is associated with a poorer prognosis in HIV-infected patients.2–4 Therefore, because of the severity of lung carcinoma in HIV-positive smokers, X-ray screening could result in an earlier diagnosis of lung carcinoma, as has been shown in HIV-negative patients.1 Although we agree that our daily practice should be based on the best available evidence, we believe that specific recommendations might be conceivable in this population, even if not yet supported by robust studies conducted in HIV-negative smokers. The same type of approach has been proposed for the screening of cervical dysplasia and carcinoma in patients infected with HIV.5 Of course, this theory may only be temporary while we await the results of controlled studies undertaken in the specific population of HIV-infected smokers.
