What are the diagnostic methods for pancreatic cancer

What are the diagnostic methods for pancreatic cancer? Most pancreatic cancer patients who come to the clinic are already in the middle or late stages. This phenomenon not only shows that pancreatic cancer is highly malignant, but also shows that people are not aware enough of the diagnosis of early pancreatic cancer. Early diagnosis of pancreatic cancer is the basis for improving the cure rate of pancreatic cancer. So what are the diagnostic methods for pancreatic cancer?

Diagnostic methods for pancreatic cancer 1. ERCP is particularly useful in identifying bile duct stones, diagnosing bile duct damage, and obtaining tissue biopsies for duodenal and ampullary cancers. If an endoscope is inserted with the help of ultrasound, it provides a new method for the diagnosis of pancreatic cancer. This technology makes it possible to diagnose pancreatic cancer in its early stages.

Diagnostic methods for pancreatic cancer 2. Ultrasound examination. Ultrasound examination is cheaper than CT, easier to obtain, and can detect liver, intrahepatic and extrahepatic bile duct tumors. Its sensitivity and specificity exceed 90%. The accuracy of ultrasound diagnosis of pancreatic cancer is limited by the operator's skills, the patient's enlarged body shape and gastrointestinal gas. Usually, pancreatic cancer ultrasound examination is used as a supplementary diagnostic method to CT.

Diagnostic methods for pancreatic cancer 3. CT scan. This scanner does not rely on surgery and is not limited by the patient's body shape and gastrointestinal gas. It can identify liver metastases, lymphatic lesions and peripheral vascular invasion, but it is unreliable for lesions less than 2 cm or small peritoneal nodules.

Diagnostic methods for pancreatic cancer 4. Magnetic resonance imaging (MRI) is not more useful than CT in the diagnosis of pancreatic cancer, and it cannot show any advantages over CT, but as a specialized technology in this field, it may play a role in the future from a development perspective.

Diagnostic methods for pancreatic cancer 5. Cytology. Fine needle aspiration (FNA) cytology under CT or ultrasound guidance can diagnose pancreatic cancer with an accuracy of 76% to 90% and a specificity of almost 100%. When there is no indication for surgery or the patient is unwilling to undergo surgery, cytology may be particularly useful for pancreatic tail, pancreatic body damage or metastatic lesions.

The above is the diagnostic method of pancreatic cancer introduced by experts.
