Key takeaways
- Preoperative radiation decisions for rectal cancer depend on T-stage, nodal status, and distance from anal verge (6cm threshold discussed)
- Endoscopic ultrasound is critical for staging early rectal cancers and distinguishing T1a from T1b lesions to guide treatment
- Endoscopic submucosal resection may be appropriate for select early rectal cancers, avoiding major surgery in carefully chosen patients
- Laparoscopic approaches are feasible for colon cancer across anatomic sites including cecum and sigmoid with appropriate technique
- Genetic workup is essential in colorectal cancer management to identify hereditary syndromes and guide surveillance strategies
