In a new study it is found the cancer patients who had diabetes earlier is likely to have greater risk of death compared with those who didn’t had. The highest mortality has been seen in those who used insulin.
According to authors of a Danish study, those cancer patients who had diabetes for 2 years and were using insulin at the time of cancer diagnosis had 4 times more mortality rate compared to those who were nondiabetics.
Researchers say the higher risk was found one year after the patients were diagnosed with cancer.
It is also reported the death risk was very less for those patients who were treated for diabetics with oral hypoglycemic agents.
The new finding is published in the Diabetologia journal.
Professor Marit Eika Jorgensen, PhD, said usually cancer is diagnosed at later and advanced stage and people with existing diabetes are offered less aggressive cancer therapy, and also the mortality is higher in cancer surgery with insulin treated diabetes.
Jorgensen is an author of the study and also professor and research manager at the Steno Diabetes Center, Gentofte, Denmark.
Theoretically it can be said the exogenous insulin may increase the tumor growth. However, this is not yet supported from randomized clinical trials.
The association of cancer, diabetes and mortality is complex, but the new study finds strong evidence in linking the risk.
The new findings were presented at the American Diabetes Association 2013 Scientific Sessions and it was then reported by Medscape Medical News.
