title: Follow-up after attempted curative surgery for colorectal cancer; postal survey of New Zealand surgeons' practice.
abstract: OBJECTIVE
  The role of follow-up after attempted curative resection of colorectal cancer (CRC) is not clearly defined. We wished to establish the frequency, duration and type of follow-up practised by New Zealand surgeons.
  
  
  METHODS
  A postal survey was performed of surgeons on the General Medical Register, asking about the follow-up of asymptomatic patients after potential curative surgery.
  
  
  RESULTS
  The response rate was 66%(107/163). There was wide variability in the frequency, duration and type of the indicated follow-up practice. 97% of surgeons followed their patients on average four monthly for the first year. At five years, 79% of surgeons followed their patients. Routine blood tests were performed 54%, while serum carcinoembryonic antigen (CEA) levels were measured by 56% of surgeons for the first two years. 41% performed abdominal imaging in the first two years. 97% of surgeons screened the remaining colon (88% by colonoscopy). 90% performed colonic screening three to five yearly.
  
  
  CONCLUSIONS
  Follow-up after potential curative surgery for CRC appears to be widely practised in New Zealand. There is, however, considerable variation between surgeons in the frequency, duration and type of follow-up. This may reflect the conflicting evidence in the literature on the value of follow-up. The outcome of current large prospective randomised trials may confirm whether or not such follow-up is worthwhile and what form it should take.
