Abstract

OBJECTIVES:

To describe factors associated with survival in human immunodeficiency virus (HIV)-infected subjects with non-small cell lung cancer (NSCLC) and analyze toxicities induced by cytotoxic chemotherapy and antiretroviral compounds.

DESIGN:

Retrospective analyses of HIV-infected subjects with NSCLC enrolled in the Dat'Aids cohort. A toxicity substudy included subjects treated by at least one cycle of cytotoxic chemotherapy.

METHODS:

Survival was analyzed using Cox models. In the toxicity substudy, factors associated with grade 4 hematological toxicity of each episode of combination of antiretroviral drugs and cytotoxic chemotherapy were analyzed using marginal logistic regression models.

RESULTS:

Fifty-two subjects were included in the study: 42 were men, median age was 48 years, 98% were smokers, with a median of 30 pack years, median CD4 was 300 cells/μl, and median survival time was 12 months. CD4 levels ≥200 cells/μl at NSCLC diagnosis (hazard ratio [HR] = 0.29, 95% confidence interval [CI] [0.10-0.89]), performance status less than 2 (HR = 0.32, 95% CI [0.15-0.68]) and highly active antiretroviral therapy (HR = 0.26, 95% CI [0.09-0.74]) were significantly associated with increased survival in the multivariable model. Forty subjects were included in the toxicity substudy, and 14 among 68 different combinations were complicated by a grade 4 hematological toxicity. Protease inhibitor use (odds ratio = 5.22, 95% CI [1.07-25.38]) was significantly associated with grade 4 hematological toxicity in the multivariable analyses.

CONCLUSIONS:

In HIV-infected patients, CD4 levels at NSCLC diagnosis may be a predictive factor of survival. Use of highly active antiretroviral therapy during NSCLC chemotherapy is warranted, but protease inhibitors should be used with caution, as they may enhance severe hematological toxicities.
