WEDNESDAY, Jan. 15, 2025 (HealthDay News) — Tobacco-associated trachea, bronchus, and lung (TBL) cancer mortality is declining, while ambient particulate matter (PM)-associated TBL cancer mortality is increasing, according to a study published in the January issue of eClinicalMedicine<\/em>.<\/p>\n Chinmay T. Jani, M.B.B.S., from the Sylvester Comprehensive Cancer Center at the University of Miami, and colleagues extracted overall and risk factor-associated TBL cancer age-standardized mortality rates (ASMRs) in the 10 most populated countries for 1990 to 2019 from the Global Burden of Disease database to examine trends.<\/p>\n The researchers found that globally, there was an 8 percent decrease in TBL cancer mortality, with a decrease for men and an increase for women. Decreases were seen in both tobacco- and air pollution-associated TBL cancer ASMRs globally. Tobacco-associated ASMRs increased in China and Indonesia, and increases in air pollution-associated ASMRs were seen in China, India, Pakistan, and Nigeria. On stratification, PM-associated mortality increased by 25 percent globally, while there was a 62 percent decrease in household-associated TBL cancer ASMRs. In 2019, China had the highest PM-associated TBL cancer ASMR (8.8\/100,000), which was twofold higher than the global average. There was a decline seen in asbestos-associated TBL cancer ASMRs, from 8.91 to 6.0\/100,000; however, for the entire study period, the rate in the United States remained twofold higher than the global average.<\/p>\n “The fluctuating trends in tobacco-associated and the concerning rise in air pollution-associated TBL cancer mortality highlight the complex interplay of societal and environmental factors,” the authors write.<\/p>\n
