Lung cancer in HIV-infected patients: the experience in Brescia from 1999 to 2009.

Lung cancer (LC) is the most common cancer among the non AIDS-defining malignancies in the highly active antiretroviral therapy (HAART) era. We described 23 HIV infected patients with a LC diagnosis followed in the Clinic of Tropical and Infectious Diseases of Brescia during the period of 1999-2009. All of these patients except two (n = 21, 91.3%) were cigarette smokers and all had at least one risk factor for developing cancer of the lung, or predisposing comorbidities, such as a COPD (chronic obstructive pulmonary disease) or a previous pneumonia. The median age at LC diagnosis was 53.6 years (range 21.2-71.4 years). Adenocarcinoma and squamous cell carcinoma were diagnosed in 10 cases (43.5%) respectively. In 21 subjects (91.3%) cancer was detected at stage IV with metastases. The median survival was 5.95 months. Greater intervention focused on the cessation of smoking is necessary, as well as the implementation of closer screening policies, especially in HIV-positive subjects with LC risk factors.
