SAN FRANCISCO — People who develop Type 2 diabetes after 60 are more likely to develop pancreatic cancer, according to a study by US researchers.
The new study by the Keck School of Medicine of the University of Southern California (USC) was published in the Journal of the National Cancer Institute on Sunday.
Pancreatic cancer is one of the most fatal cancers, with a five-year survival rate of only 8 percent because majority pancreatic cancer patients are diagnosed at a late stage.
The researchers studied the data of about 49,000 African-Americans and Latinos, two ethnic groups with a high rate of diabetes, and concluded that people diagnosed with diabetes between the ages of 65 and 85 were more likely to develop pancreatic cancer within three years as compared with people without diabetes.
According to the study, latinos were fourfold more likely to develop pancreatic cancer within three years of a diabetes diagnosis, and African-Americans three times more likely.
“Because most people with pancreatic cancer are diagnosed at a late stage, the five-year survival rate is low — about 8 percent. Identifying people who are at high risk early on could potentially save their lives,” said V Wendy Setiawan, associate professor of preventive medicine at Keck and lead author of the research.
The diagnosis of late-onset diabetes may offer an opportunity to screen high-risk groups with new tools such as liquid biopsy, a test that looks for cancer cells or DNA from cancer cells in the blood, Setiawan said.

Women with diabetes have higher cancer risk : Study
SYDNEY — The increased risk of cancer in people with diabetes is higher for women than men, according to a major study by Australian researchers.
Women with diabetes were also at greater risk than men of getting leukemia and stomach, mouth and kidney cancers, the George Institute for Global Health medical research group said in a statement on Friday.
Previous research identified the link between diabetes and cancer risk, but this study looked at whether that risk differs between men and women.
Among people with diabetes, women have a 6 percent higher risk of cancer than men, the researchers said in the study, published in the journal Diabetologia.
For women with type 1 or type 2 diabetes, the cancer risk is 27 percent higher compared to other women. And men with diabetes have a 19 percent higher cancer risk than men who don’t have the blood sugar disease, the findings showed.
And, for men the risk was 19 percent higher. The numbers “highlight the need for more research into the role diabetes plays in developing cancer” and “demonstrate the increasing importance of sex specific research,” said the researchers.
And based on the researchers’ analysis of data from 47 studies, diabetics of both sexes are at greater risk of cancer than people without diabetes.
“Further studies are needed to clarify the mechanisms underlying the sex differences in the diabetes-cancer association,” the study authors concluded.
Cancer is the second leading cause of death worldwide, accounting for 8.7 million deaths in 2015. About one in four women and one in three men will develop cancer during their lifetime, the study authors noted in a journal news release.
Similary, diabetes affects more than 415 million people worldwide, with 5 million deaths linked to it every year.
