Magnetic resonance imaging in restaging rectal cancer after neoadjuvant chemoradiotherapy.
PURPOSE To evaluate the accuracy of magnetic resonance imaging (MRI) for restaging locally advanced nonmucinous rectal cancer after neoadjuvant chemoradiotherapy (CRT). METHODS A total of 94 consecutive patients with histologically proven locally advanced middle or low located nonmucinous rectal adenocarcinoma, who were treated with preoperative CRT, followed by radical surgery 6-8 weeks late...
متن کاملThe value of metabolic imaging to predict tumour response after chemoradiation in locally advanced rectal cancer
BACKGROUND We aim to investigate the possibility of using 18F-positron emission tomography/computer tomography (PET-CT) to predict the histopathologic response in locally advanced rectal cancer (LARC) treated with preoperative chemoradiation (CRT). METHODS The study included 50 patients with LARC treated with preoperative CRT. All patients were evaluated by PET-CT before and after CRT, and re...
متن کاملProspective assessment of imaging after preoperative chemoradiotherapy for rectal cancer.
BACKGROUND The aim of the study was to assess the accuracy of imaging techniques in predicting pathologic tumor (ypT), node (ypN) stages and the circumferential resection margin (ypCRM) status of rectal cancers after preoperative chemoradiotherapy (CRT). METHODS Using pelvic computed tomography (CT), magnetic resonance imaging (MRI), and endorectal ultrasound (ERUS), 90 consecutive patients w...
متن کاملChemoradiotherapy response in recurrent rectal cancer
The efficacy of response to preoperative chemoradiotherapy (CRT) in recurrent versus primary rectal cancer has not been investigated. We compared radiological downsizing between primary and recurrent rectal cancers following CRT and determined the optimal size reduction threshold for response validated by survival outcomes. The proportional change in tumor length for primary and recurrent recta...
متن کاملOptimal timing of computed tomography for assessing lymph nodes after neoadjuvant chemoradiotherapy for rectal cancer
Background: This study assessed the optimal timing of computed tomography for detection of metastatic disease in locoregional lymph nodes in patients with rectal cancer who have undergone chemoradiotherapy. Materials and Methods: This observational retrospective study was performed in a single institution. All patients with locally advanced rectal cancer treated with chemoradiotherapy, followed...
