| Abstract: | Increased glucose metabolism has been reported to occur in association with colorectal cancer. As positron emission tomography
(PET) using 18F]fluorodeoxyglucose is able to depict hypermetabolic sites, it can therefore be used to detect colorectal cancer. A 69-year-old
male patient with a recurrent solitary liver metastasis from colon cancer underwent whole-body PET which revealed high 18F]fluorodeoxyglucose uptake in the lesion. Furthermore, PET revealed peritoneal metastases that had not been detected by conventional
imaging methods. Consequently, PET proved useful in helping us to avoid performing unnecessary treatment for the liver metastasis.
Although it is uncertain whether early identification of recurrence can prolong survival, it may help to prevent unnecessary
treatments being carried out. Thus, the application of PET in carefully selected patients could be beneficial to the management
of recurrent colorectal cancer. |
