Abstract
AIM: To describe the patterns of recurrence in a contemporaneous cohort of patients undergoing surgery with curative intent for colorectal adenocarcinoma at a New Zealand hospital with five-year follow-up. METHODS: Patients with colorectal cancer undergoing potentially curative surgery between January 2010 and December 2012 were followed up for a median of 61 months with three-monthly CEA (carcinoembryonic antigen), a colonoscopy after one year and yearly computed tomography scans of the chest, abdomen and pelvis for the first three years. RESULTS: Overall, 59/237 (24.9%) of patients experienced disease recurrence, the most common sites being the liver, followed by the lung and local recurrence. Recurrence rates did not differ significantly between colon and rectal cancer and ranged from 5.1% in stage I to 60% in stage IV. Seventy-three percent of all recurrences were observed within the first 24 months post-operatively. CONCLUSION: While New Zealand outcomes in colorectal cancer have historically compared unfavourably against international standards, the outcomes observed in this cohort are encouraging and may reflect advances in care, including multidisciplinary team discussion, increased use of adjuvant therapy, surgical subspecialisation and protocolled surveillance and follow-up.
