The presence of oral bacteria in so-called cystic pancreatic tumours is associated with the severity of the tumour, a study by researchers at Karolinska Institutet in Sweden published in the journal Gut reports. It is hoped that the results can help to improve diagnosis and treatment of pancreatic cancer.
Pancreatic cancer is one of the most lethal cancers in the west. The disease is often discovered late, which means that in most cases the prognosis is poor. But not all pancreatic tumours are cancerous. For instance there are so-called cystic pancreatic tumours (pancreatic cysts), many of which are benign. A few can, however, become cancerous.
It is currently difficult to differentiate between these tumours. To rule out cancer, many patients therefore undergo surgery, which puts a strain both on the patient and on the healthcare services. Now, however, researchers at Karolinska Institutet have found that the presence of bacteria inside the cystic tumours is linked to how severe the tumour is.
“We find most bacteria at the stage where the cysts are starting to show signs of cancer,” says corresponding author Margaret Sällberg Chen, docent and senior lecturer at the Department of Dental Medicine, Karolinska Institutet. “What we hope
