5 Key Takeaways

• 1

  Fluorine-18 fluorodeoxyglucose PET/CT may enhance early detection of local tumor progression in colorectal liver metastases post-treatment.

• 2

  In a study of 64 patients, disease progression was confirmed in 66% at first follow-up, with local tumor progression in 25% of cases.

• 3

  F-18 FDG PET/CT showed greater diagnostic accuracy for local tumor progression compared to contrast-enhanced CT after treatment.

• 4

  CEA testing was ineffective as a standalone marker, yielding false-negative results in 43% of patients with disease progression.

• 5

  The study's limitations include its single-center design and reliance on multidisciplinary consensus for most diagnoses.
