What are the most important tests for pancreatic cancer

According to the NCCN Guidelines for Pancreatic Cancer (2023), the essential initial tests include:

1. Imaging Studies:

• CT scan with contrast (specifically pancreas protocol CT) is the gold standard
• MRI/MRCP if CT cannot be performed or for better visualization of the bile ducts
• These help determine tumor location, size, and if it has spread

1. Laboratory Tests: The American Cancer Society and NCCN recommend:

• Tumor markers: CA 19-9 (most important)
• Liver function tests
• Complete blood count
• Basic metabolic panel

According to ASCO Guidelines, additional tests may be needed based on individual cases:

1. Biopsy:

• Fine needle aspiration (FNA) guided by endoscopic ultrasound (EUS)
• This confirms the diagnosis and provides tissue for analysis

The National Cancer Institute emphasizes that staging tests are crucial and may include:

• PET/CT scans (if metastatic disease is suspected)
• Endoscopic ultrasound (EUS) to determine tumor involvement with blood vessels
• Diagnostic laparoscopy (in specific cases)

Always consult with your healthcare team about which tests are most appropriate for your specific situation, as test selection depends on various factors including symptoms, tumor location, and stage of disease.
