TL;DR: One in every 100 patients without COVID-19 symptoms tested positive for SARS-CoV-2 with RT-PCR; this yield increased in conjunction with community prevalence, and the added value of chest CT was limited.
Journal ArticleDOI
Whole-body diffusion-weighted magnetic resonance imaging: current evidence in oncology and potential role in colorectal cancer staging.
Doenja M. J. Lambregts,Monique Maas,Vincent C. Cappendijk,Leonne M. Prompers,Felix M. Mottaghy,Geerard L. Beets,Regina G. H. Beets-Tan +6 more
TL;DR: This review aims to evaluate the current evidence for WB-DWI in oncology, to discuss its potential for the WB staging of (colo)rectal cancer and to relate it to the established WB techniques.
Journal ArticleDOI
Role of preoperative local and distant staging in rectal cancer.
TL;DR: For the prediction of the nodal status none of the three imaging modalities - EUS, MRI and CT - can be reliably used for clinical decisionmaking, and only MRI using lymph node specific contrast seems promising for the detection of nodal disease.
Journal ArticleDOI
Light Physical Activity Is Associated with Quality of Life after Colorectal Cancer.
Eline H. van Roekel,Martijn J.L. Bours,José J.L. Breedveld-Peters,Kenneth Meijer,IJmert Kant,Piet A. van den Brandt,Silvia Sanduleanu,Geerard L. Beets,Matty P. Weijenberg +8 more
TL;DR: Self-reported LPA, besides MVPA, was beneficially associated with multiple HRQoL outcomes in colorectal cancer survivors, especially in women and survivors with multiple comorbidities.
Journal ArticleDOI
Impact of radiotherapy on anorectal function in patients with rectal cancer following a watch and wait programme.

TL;DR: This is the first study to investigate the late dose-volume effects of radiotherapy specifically on the anorectal function in rectal cancer patients and observed trends towards worse long-term anoreCTal function after higher anal sphincter complex radiotherapy dose.
