Shared Decision-Making in the Surgical Management of Rectal Cancer: Comparing Low Anterior Resection and Abdominoperineal Resection Using a Patient Decision Aid
Bibliographic record
Abstract
Abstract Low rectal cancer is surgically managed with one of two primary procedures: low anterior resection (LAR) or abdominoperineal resection (APR). Each procedure has a unique profile of potential complications, oncologic outcomes, and quality-of-life impacts. The acceptability of these outcomes is highly driven by patient values. Consequently, shared decision-making is essential to selecting the optimal procedure for each patient. Evidence has shown that patient decision aids (PtDAs) improve patient knowledge, reduce decisional conflict, and support value-congruent decisions. This review describes the development of a rectal cancer PtDA for the choice between LAR and APR. This PtDA was designed according to the International Patient Decision Aid Standards and Ottawa Decision Support Framework. Evaluation of this rectal cancer PtDA demonstrated increased patient knowledge, reduced decisional conflict, and enhanced patient preparedness for decision-making. Despite strong evidence for their utility, PtDAs remain underutilized. This review highlights key barriers in implementing PtDAs and proposes strategies to facilitate the effective integration of PtDAs into surgical practice.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
