It is well known that smoking is injurious to health and causes lung cancer, but a recent study has found that smoking is fatal for diabetic patients.
A study, presented at the annual meeting of the Radiological Society of North America (RSNA) in Chicago, US, suggested that heavy smokers with diabetes are at increased risk of death.
‘The study found that diabetes doubles the risk for all-cause mortality and non-lung cancer mortality among heavy smokers,’ said Kavita Garg, Professor at the University of Colorado-Denver, in the US.
In the study, nearly 13 per cent of patients with diabetes died as compared to 6.8 per cent of patients without diabetes. Participants with diabetes tended to be older, reported more pack-years of smoking, and had a higher BMI than those without diabetes. In addition, the study also found that women with diabetes have an increased risk of lung-cancer mortality. However, the same effect was not found in men, the researchers observed. For the study, Garg and colleagues conducted an analysis on 53,454 participants from US on the relative risk for overall mortality, lung cancer mortality and non-lung cancer mortality associated with diabetes.
Over the course of the study, there were 3,936 total deaths, including 1,021 from lung cancer and 826 from non-lung cancers. Garg emphasized that smokers should undergo lung cancer screening as well control their diabetes.
‘Patients have to take care of their diabetes to maximize the benefit of CT screening for lung cancer. It truly makes a magnitude of difference in mortality risk,’ Garg noted.
