Pancreatic cancer remains a formidable health challenge, with a notoriously low survival rate and often late-stage diagnoses. New research published today in JAMA Network Open sheds light on a previously underappreciated risk factor for the disease: chronic Hepatitis C virus (HCV) infection. A large-scale analysis of over 6.3 million patients revealed that those with chronic HCV were 1.8 times more likely to develop pancreatic cancer, highlighting the potential for preventative measures through increased screening and treatment of the widespread viral infection.

A new American study has identified an unexpected risk factor for pancreatic cancer, a particularly deadly form of the disease that is often diagnosed at a late stage. Researchers at Yale School of Medicine have found a significant link between chronic infection with Hepatitis C virus (HCV) and an increased risk of developing pancreatic cancer.
The findings, published in JAMA Network Open, analyzed data from over 6.3 million patients. The analysis revealed that individuals with a confirmed chronic HCV infection were 1.8 times more likely to develop pancreatic cancer compared to those without the virus. The study also indicated that smoking and diabetes further elevate the risk, by 20% to 30%, according to Lenta.ru.
Researchers emphasize that HCV is a modifiable risk factor, suggesting that increased screening and early treatment could substantially reduce the incidence of pancreatic cancer. Modern antiviral treatments are now able to cure more than 95% of patients infected with the virus, though a substantial number of cases remain undiagnosed. Early detection and treatment are crucial, as pancreatic cancer has a low survival rate and is often difficult to treat effectively.
Even individuals exposed to the virus who did not develop a chronic infection showed a slight increase in risk, the researchers noted. Preliminary results suggest that certain genetic patterns of the virus, specifically genotypes 1 and 3, are associated with an additional increase in risk.
This research highlights the importance of understanding the complex interplay between viral infections and cancer development. Identifying and addressing modifiable risk factors like HCV infection is a key step in improving pancreatic cancer prevention efforts.
