Journal ArticleDOI
Long-term outcome in patients with a pathological complete response after chemoradiation for rectal cancer: a pooled analysis of individual patient data
Monique Maas,Patty J. Nelemans,Vincenzo Valentini,Prajnan Das,Claus Rödel,Li Jen Kuo,Felipe A. Calvo,Julio Garcia-Aguilar,Rob Glynne-Jones,Karin Haustermans,Mohammed Mohiuddin,Salvatore Pucciarelli,William Small,Javier Suárez,George Theodoropoulos,Sebastiano Biondo,Sebastiano Biondo,Regina G. H. Beets-Tan,Geerard L. Beets +18 more
TL;DR: Patients with pCR after chemoradiation have better long-term outcome than do those without pCR, and pCR might be indicative of a prognostically favourable biological tumour profile with less propensity for local or distant recurrence and improved survival.
Journal ArticleDOI
Wait-and-See Policy for Clinical Complete Responders After Chemoradiation for Rectal Cancer
Monique Maas,Regina G. H. Beets-Tan,Doenja M. J. Lambregts,Guido Lammering,Patty J. Nelemans,Sanne M. E. Engelen,Ronald M. van Dam,Rob L. H. Jansen,Meindert N. Sosef,Jeroen W. A. Leijtens,Karel W.E. Hulsewé,Jeroen Buijsen,Geerard L. Beets +12 more
TL;DR: A wait-and-see policy with strict selection criteria, up-to-date imaging techniques, and follow-up is feasible and results in promising outcome at least as good as that of patients with a pCR after surgery.
Journal ArticleDOI
Accuracy of magnetic resonance imaging in prediction of tumour-free resection margin in rectal cancer surgery.

TL;DR: MRI with a phased-array coil showed moderate accuracy and reproducibility for predicting the tumour stage of rectal cancers, allowing preoperative identification of patients at risk of recurrence who will benefit from preoperative radiotherapy, more extensive surgery, or both.
Journal ArticleDOI
Neoadjuvant immunotherapy leads to pathological responses in MMR-proficient and MMR-deficient early-stage colon cancers.

TL;DR: The data indicate that neoadjuvant immunotherapy may have the potential to become the standard of care for a defined group of colon cancer patients when validated in larger studies with at least 3 years of disease-free survival data.
Journal ArticleDOI

TL;DR: This dataset has the largest series of patients with rectal cancer treated with a W&W approach, consisting of approximately 50% data from previous cohort series and 50% unpublished data.
