Abstract
Whole-body positron emission tomography (WB PET) was performed preoperative ly in 24 patients with primary colorectal cancer, and the results were comp ared with the histopathological findings. The PET positive rate was 95.8% ( 23/24 patients) for the primary tumor. Among nine patients with histologica lly confirmed lymph node metastasis, two (22.2%) were positive by PET, incl uding one with nl and one with n4 disease. Among 15 patients without lymph node metastasis histopathologically (n0), two (13.3%) showed false-positive nodes on PET, being diagnosed as nl and n3 disease, respectively. These re sults suggest that preoperative PET is useful for the diagnosis of primary colorectal cancer, but it is of limited value for detecting metastasis to t he regional lymph nodes surrounding the primary lesion.
