Q: Pre-operative restaging CT scans are often performed routinely following neoadjuvant chemoradiotherapy for locally advanced rectal cancer. There is a paucity of data on the utility of this common practice. We sought to determine how often restaging CTs identified disease progression or regression that altered management.', 'We performed a single-institution retrospective study. From 2007 to 2011, 182 patients had newly-diagnosed, non-metastatic rectal adenocarcinoma, of which 96 were surgical candidates with clinical stage II/III disease. Ninety-one of these patients (95%) completed neoadjuvant chemoradiation.', 'Eighty-three out of 91 patients (91%) had restaging CTs. Four patients (5%) had new lesions suspicious for distant metastasis (2 lung, 2 liver) on restaging CT scan reports (1 of these was present on initial staging CT but not reported). All 4 patients had node-positive disease. In no case did restaging CT result in a change in surgical management.
