• Recurrence suppression and mechanistic understanding of local recurrence after colorectal cancer surgery, emphasizing possible tumor implantation at suture lines and the importance of margins and radical resections to reduce recurrence [2], [5], [6], [1], [20], [19].

• Polyps as critical cancer precursors: historical studies unify observations on adenomatous polyps, polyps’ malignant potential, and implications for screening, pathologic characterization, and management [4], [3], [14], [15], [16], [17], [11].

• Sphincter-preserving rectal cancer surgery and standardization: a shift from permanent colostomy to sphincter-sparing operations with planned dissection extent, contributing to functional outcomes and technique standardization [1], [10], [13], [18].

• Margins and dissection planning in pelvic colon and rectal cancer: analysis of distal/proximal margins and proximal extent standardization to minimize residual disease and recurrences across multiple surgical approaches [20], [19], [18], [13].
