Watch-and-wait may be an option for rectal cancer patients, but specific conditions must be met to avoid worse outcomes.

• Salvage rates below 75% threaten disease-free survival; rates must stay above this for safety.
• Ten-year overall survival rates are similar: 83.0% for watch-and-wait vs. 81.5% for surgery.

Monitoring regrowth rates is essential; if it exceeds 10% every six months or near-complete responders exceed 68%, immediate surgery is likely safer.

• Utilize these thresholds for patient counseling and surgical decision-making.
