TL;DR: Local recurrence may develop in 31% of patients with initial cCR when early regrowths (≤ 12 months) and late recurrences are grouped together, and more than half of these recurrence develop within 12 months of follow-up.

TL;DR: A WW strategy for select rectal cancer patients who had a clinical complete response after neoadjuvant therapy resulted in excellent rectal preservation and pelvic tumor control; however, in the WW group, worse survival was noted along with a higher incidence of distant progression in patients with local reg growth vs those without local regrowth.

TL;DR: The data suggest that nCRT followed by LE may be considered as an organ-preserving alternative in carefully selected patients with clinically-staged T2N0 tumours who refuse, or are not candidates for, transabdominal resection.

TL;DR: Assessment of tumor response with positron emission tomography/computed tomography (PET/CT) after neoadjuvant treatment may offer relevant information for the selection of patients to receive alternative treatment strategies.

TL;DR: A local failure rate of 15% after transanal endoscopic microsurgery for patients with residual rectal cancers restricted to the bowel wall (ypT0-2) may limit the indication of this procedure to highly selected patients as an alternative to standard radical total mesorectal excision.
