Lung cancer patients with diabetes tend to live longer than patients without diabetes, according to a new study from Norway due to be published in the November issue of the Journal of Thoracic Oncology. The researchers did not offer an explanation for the tendency; they suggested it needs further investigation, and diabetes should not be considered as a reason to withhold standard cancer therapy.

In their background information, the researchers, from Norwegian University of Science and Technology and Trondheim University, write that patients with lung cancer often have other diseases, one of them being diabetes. However, evidence on the impact of diabetes on lung cancer survival is conflicting, so they wanted to do a large study focusing on this.
