Background: A metastasis from colorectal cancer (CRC) can be resected with curative intent. CT scan is useful to detect small metastases, though it is unclear whether scheduled CT scan improves the survival of patients with curatively resected CRC or not.

THE ROLE OF SCHEDULED CT FOLLOW-UP IN PATIENTS WITH CURATIVELY RESECTED COLORECTAL CANCER
Methods: We investigated retrospectively 331 CRC patients had undergone curative resection for primary lesion from Jan 2006 to Dec 2007. It was examined that the correlation between survival and receiving scheduled CT scan. Results: The median age of patients was 62 years. There were 154 colon and 177 rectal cancer patients. LN metastases were detected in 125 patients and were not in 206 patients. pStage 0/I/II/IIIa/IIIb were 3/96/107/93/32, respectively. 216 patients underwent scheduled CT scan (scheduled CT group) and 115 patients did not (without CT group). Tumor recurrence were detected in 40 patients in scheduled CT group (18.5%) and 11 in without CT group (10.6%). In scheduled CT group, 85% of recurrence was detected with a single site of metastasis. On the other hand, in without CT group, only 45% recurrence was detected with a single site. As a result, curative resection of metastasis was done in 58% of scheduled CT group and 45% of without CT group, respectively. In patients who suffered from recurrence, scheduled CT demonstrated a tendency to improve overall survival (P = 0.141). In all patients scheduled CT scan didn’t improve the survival, while in pStage II/III patients only, overall survival was slightly better in scheduled CT group ( p = 0.526). Conclusion: Scheduled CT scan may improve the survival of curatively resected CRC patients.
