Abstract
Purpose: The goal of this study is to elucidate the role of 18-FDG PET-CT in assessment of colo-rectal cancer
Methods: Twenty five patients with histopathologically proven colorectal primary malignancy were evaluated for suspected local recurrence and metastasis using PET/CT. No age predilection and both sexes were included, Clinical information, image follow-up, tumour markers, and pathological reports of the patients were reviewed for gold standard
Results: The final diagnosis of distant metastasis and/or local recurrence in post- therapeutic cancer colon was evident in 70% of our patient population with PET /CT sensitivity of 95.6%, specificity of 91.4%, (NPV) of 88.9%, (PPV) of 96.7%, and diagnostic efficacy of 94.4% and CT sensitivity of 62.6%, specificity of 48.6, (NPV) of 33.3% (PPV) of 76.0%, and diagnostic efficacy of 58%
Conclusion: PET/CT is a better method to evaluate colorectal cancer patients with significantly higher specificity and sensitivity.
