Diabetes may prolong life for lung cancer patients

In fact, the researchers found that the one-year survival rate of patients with lung cancer and diabetes was 43%, compared with 28% among those who did not have diabetes. 

Two-year survival was 19% for those with diabetes, and 11% for those without.

Additionally, patients with diabetes were less likely to have metastatic diseases. This may partly explain the survival benefit since most lung cancer patients die from metastases rather than the primary tumour, the researchers wrote.

However, survival benefit remained even after adjusting for the stage of disease.
