Question 5

Answer 5

Patients suspected of having a locoregional recurrence should undergo comprehensive restaging, including a computed tomography (CT) scan of the chest, abdomen, and pelvis and a colonoscopy.

PET scan is indicated if staging CT scans are negative (gerater sensitivity for distant metastatic disease)

Question 6

What is the survival for patients who underwent an R0 resection of colon cancer?

Answer 6

three-year overall survival of 58 percent

Question 7

What is R0 resection?

Answer 7

microscopic negative margins

Question 8

What is the posttreatment surveillance for stage II or III CRC?

Answer 8

posttreatment surveillance usually consists of

• periodic history and physical examination (q3-6mo)
• serial assay of the serum concentrations CEA (q3-6mo)
• annual surveillance CT scans (q6-18mo)
• colonoscopy to detect metachronous primaries (at 1y then q3-5y)

Most of these recommendations last for approx 5y

Question 9

What is CEA?

Answer 9

tumor marker: carcinoembryonic antigen
