Marie-Claude Rousseau, lead author on the study, compared 3,288 men diagnosed with 12 different cancer types to 509 healthy individuals, in order to determine whether those reporting a prior diagnosis of diabetes were more likely to have cancer.
"Among those who reported being diabetic, there was a three-fold increased risk for liver cancer," said Rousseau, a postdoctoral fellow in Epidemiology at the Université de Montréal, Montreal, Canada. "When we looked at the individuals who reported taking medication for their diabetes, the risk for liver cancer increased to almost four-fold, compared to individuals who were not diabetic." Rousseau noted that these findings were independent of the body mass index of the individuals.
In this study, diabetics did not have increased risks for other cancer types, including melanoma, non-Hodgkin's lymphoma, cancers of the esophagus, stomach, colon, rectum, lung, prostate, bladder, and kidney.
Rousseau, who is funded by the Canadian Cancer Society through the National Cancer Institute of Canada, conducted this research with her colleagues Jack Siemiatycki at the Université de Montréal, and Marie-Élise Parent, at the INRS-Institut Armand-Frappier, Laval, Quebec, Canada.
Founded in 1907, the American Association for Cancer Research is a professional society of more than 24,000 laboratory, translational, and clinical scientists engaged in all areas of cancer research in the United States and in more than 60 other countries. AACR's mission is to accelerate the prevention and cure of cancer through research, education, communication, and advocacy. Its principal activities include the publication of five major peer-reviewed scientific journals: Cancer Research; Clinical Cancer Research; Molecular Cancer Therapeutics; Molecular Cancer Research; and Cancer Epidemiology, Biomarkers & Prevention. AACR's Annual Meetings attract more than 15,000 participants who share new and significant discoveries in the cancer field. Specialty meetings, held throughout the year, focus on the latest developments in all areas of cancer research.
