"A retrospective analysis of a clinical trial in American Indian (AI) and Alaska Native (AN) school children found that childhood administration of the bacille Calmette-Guerin (BCG) vaccine — currently the only approved tuberculosis (TB) vaccine around the globe — was associated with a reduced risk of lung cancer development later in life, researchers reported.
The live attenuated BCG vaccine has proven highly effective at preventing extrapulmonary disseminated TB and TB meningitis, but previous research from Puerto Rico, Georgia and Alabama, Great Britain, and New Zealand has suggested that the vaccine is associated with increased incidence of leukemia and lymphoma in recipients. However, Naomi E. Aronson, MD, of the Infectious Diseases Division at the Uniformed Services University of the Health Sciences in Bethesda, Maryland, and colleagues noted that other analyses suggested no difference or decreased leukemia incidence and mortality, while a systematic review associated the vaccine with a nonsignificant reduction in childhood leukemia.
To determine the association between the BCG vaccine and subsequent cancer development, Aronson and colleagues conducted a 60-year follow-up analysis of a clinical trial of BCG vaccination in AI/AN populations.
In this analysis, BCG vaccine recipients had a significantly lower risk of lung cancer than placebo recipients (HR, 0.38; 95% CI, 0.20-0.74) controlling for sex, region, alcohol overuse, smoking status, and TB," they wrote. " This represents an associated 2.5-fold decrease in lung cancer among those receiving BCG vaccine. Lung cancer was the only cancer type that was associated with BCG vaccination in this study;
