PET Scans Lead to Treatment Changes in Majority of Colorectal Cancer Patients

Reston, Va.—In the largest multi-institutional study to date examining the impact of positron emission tomography (PET) in changing disease management of individuals with suspected recurrent colorectal cancer, researchers found that treatment plans were changed for more than half of patients, according to an article in the September issue of The Journal of Nuclear Medicine.

The study was conducted at four sites throughout Australia and comprised 191 patients who were divided into two groups. Group A consisted of symptomatic patients who had residual structural lesions suspicious for recurrent tumor after initial therapy. Group B comprised patients with pulmonary or hepatic metastases that were potentially operable. These results were compared with findings from conventional imaging (such as computed tomography or CT), and participants were followed for 12 months.
