"Long-term oncologic outcomes and risk factors for distant recurrence after pathologic complete response following neoadjuvant treatment for locally advanced rectal cancer. A nationwide, multicentre study".

Background: Pathologic complete response (pCR) after multimodal treatment for locally advanced rectal cancer (LARC) is used as surrogate marker of success as it is assumed to correlate with improved oncologic outcome. However, long-term oncologic data are scarce.

Methods: This retrospective, multicentre study updated the oncologic follow-up of prospectively collected data from the Spanish Rectal Cancer Project database.

Completion Surgery in Unfavorable Rectal Cancer after Transanal Endoscopic Microsurgery: Does It Achieve Satisfactory Sphincter Preservation, Quality of Total Mesorectal Excision Specimen, and Long-term Oncological Outcomes?

Background: Unfavorable adenocarcinoma after transanal endoscopic microsurgery requires "completion surgery" with total mesorectal excision. The literature on this procedure is very limited.

Objective: This study aims to assess the percentage of transanal endoscopic microsurgery that will require completion surgery.
