Summary
Brief summary (as posted)
residual mucosal lesions in patients with locally advanced rectal cancer after CRT are still confusing for decision to continue follow up or excise. Investigators decided to compare two groups with cCR or nCR with MDT management decision to whether do ESD for this residual lesion or continue follow up and its effect on disease free survival.

Inclusion Criteria: * Adult patients with rectal adenocarcinoma who underwent full course locoregional chemoradiotherapy with organ-preservation intent. Post-CRT assessment showing either: A. Small residual mucosal/submucosal lesion amenable to en-bloc ESD (CRT→ESD), OR B. Clinical/radiologic near-complete/complete response and decision to observe (CRT→Follow-up). Exclusion Criteria: * \- Evidence of distant metastasis at post-CRT restaging. * Lesions unsuitable for endoscopic resection (circumferential, deeply invasive on EUS/MRI). * Patients who had immediate TME after CRT for other reasons. * Unfit for endoscopy or follow-up.
