Data from Cigarette Smoking and Pulmonary Function in Adult Survivors of Childhood Cancer Exposed to Pulmonary-Toxic Therapy: Results from the St. Jude Lifetime Cohort Study

Abstract: Treatments for childhood cancer can impair pulmonary function. We assessed the potential impact of cigarette smoking on pulmonary function in 433 adult childhood cancer survivors (CCS) who received pulmonary-toxic therapy, using single breath diffusion capacity for carbon monoxide corrected for hemoglobin (DLCOcorr), forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and total lung capacity (TLC). FEV1/FVC median values among current [1.00; interquartile range (IQR): 0.94–1.04] and former smokers (0.98; IQR: 0.93–1.04) were lower than those who had never smoked (1.02; IQR: 0.96–1.06; P = 0.003). Median FEV1/FVC values were lower among those who smoked ≥ 6 pack-years (0.99; IQR: 0.92–1.03) and those who smoked <6 pack-years (1.00; IQR: 0.94–1.04), than among those who had never smoked (P = 0.005). Our findings suggest that CCSs have an increased risk for future obstructive and restrictive lung disease. Follow-up is needed to determine whether smoking imparts more than additive risk. Smoking prevention and cessation need to be a priority in this population. Cancer Epidemiol Biomarkers Prev; 23(9); 1938–43. ©2014 AACR.
