BACKGROUND: α1-Antitrypsin deficiency is characterized by elevated elastase activity and excessive elastin degradation, which may impact cancer development and progression. We tested the hypothesis that individuals with α1-antitrypsin deficiency have increased susceptibility to cancer in the Danish population.
METHODS: In a nationwide nested study, we identified 2702 individuals with α1-antitrypsin deficiency and 26,750 control subjects without α1-antitrypsin deficiency matched on age, sex, and municipality. We recorded admissions due to cancer as outcomes during a median follow-up of 62 years.
RESULTS: Individuals with α1-antitrypsin deficiency versus control subjects had an increased hazard of skin cancer (2.18, 95%CI: 1.81-2.63), leukemia (1.76, 1.12-2.79), liver cancer (3.91, 2.23-6.85), and cancer overall (1.25, 1.13-1.38). Corresponding hazard ratios when the entire Danish population was used as control group were 3.02 (2.55-3.58), 1.83 (1.19-2.81), 4.46 (2.74-7.28), and 1.45 (1.31-1.59). When the analysis was stratified according to comorbidities, the hazard for skin cancer was higher in those with chronic obstructive pulmonary disease (COPD) (3.59, 2.60-4.95) and skin disease (2.93, 2.19-3.92) but remained elevated in those without any of these diseases. Hazards for skin cancer in individuals with α1-antitrypsin deficiency were similar when stratified by liver cirrhosis and ischemic heart disease (ps for interaction: ≥0.76). Hazards for liver cancer in individuals with α1-antitrypsin deficiency versus control subjects were similar when stratified according to liver cirrhosis, COPD, skin disease, and ischemic heart disease (ps for interaction: ≥0.13).
CONCLUSION: Individuals with α1-antitrypsin deficiency have increased risks of skin cancer, leukemia, and liver cancer in the Danish population.
