The Future of Rectal Cancer Surgery: A Narrative Review of an International Symposium
Bibliographic record
Abstract
Surgery remains the mainstay of curative treatment for primary rectal cancer. For mid and low rectal tumors, optimal oncologic surgery requires total mesorectal excision (TME) to ensure the tumor and locoregional lymph nodes are removed. Adequacy of surgery is directly linked to survival outcomes and, in particular, local recurrence. From a technical perspective, the more distal the tumor, the more challenging the surgery and consequently, the risk for oncologically incomplete surgery is higher. TME can be performed by an open, laparoscopic, robotic or transanal approach. There is a lack of consensus on the "gold standard" approach with each of these options offering specific advantages. The International Symposium on the Future of Rectal Cancer Surgery was convened to discuss the current challenges and future pathways of the 4 approaches for TME. This article reviews the findings and discussion from an expert, international panel.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
