PET/CT and Histopathologic Response to Preoperative Chemoradiation Therapy in Locally Advanced Rectal Cancer

Abstract

We conclude that positron emission tomography/computer tomography performed seven weeks after the end of chemoradiation is not able to predict the histopathologic response in locally advanced rectal cancer. There is an obvious need for other complementary methods especially with respect to the low sensitivity of positron emission tomography/computer tomography.
