[Gallbladder cancer staging with 18F-FDG PET-CT]

Area of Science:

• Oncology
• Medical Imaging

Background:

• Gallbladder cancer is the most common biliary tract neoplasm, typically affecting the elderly.
• The disease is often asymptomatic until advanced stages, leading to late diagnosis and poor prognosis.
• Surgical resection is the only curative treatment, feasible only in early disease stages.

Observation:

• Conventional diagnostic imaging includes ultrasonography, CT, and MR cholangiography.
• Positron emission tomography (PET) using fluorodeoxyglucose (FDG) is an emerging diagnostic tool.
• PET-CT scans offer hybrid imaging capabilities for enhanced visualization.

Findings:

• PET-FDG demonstrated utility in the pre-surgical staging of gallbladder cancer.
• The presented cases illustrate the value of PET-FDG in assessing tumour extent.
• This imaging modality can provide crucial information for surgical planning.

Implications:

• Improved pre-surgical staging of gallbladder cancer can lead to more accurate treatment decisions.
• Early and precise diagnosis facilitated by PET-FDG may enhance patient outcomes.
• The integration of PET-FDG into diagnostic algorithms could optimize management strategies for biliary tract cancers.
