Follow-up practices for patients with early stage breast cancer: a survey of Canadian oncologists.

Abstract

The value of routine follow-up programs for patients with early stage breast cancer remains an area of controversy. In recent years, the cost-effectiveness of routine investigations has been questioned, and 2 prospective randomized clinical trials have shown no survival advantage to more intensive diagnostic follow-up approaches. Under the auspices of the Ottawa Regional Cancer Centre, a national survey of the practice patterns of Canadian surgical, radiation and medical oncologists was undertaken to measure current Canadian standards of care and to determine average costs of 5-year follow-up for patients completing primary treatment for stage I and II breast cancer. Standardized questionnaires were sent out to 130 surgeons, 59 radiation oncologists and 89 medical oncologists. The overall response rate was 44%. Based on the frequency of follow-up visits and investigations recommended by respondents, an average cost per patient for a 5-year follow-up plan was derived for each subspecialist group: $791, $911 and $904 for surgeons, radiation oncologists and medical oncologists respectively. Use of a less interventionist follow-up program was estimated to result in a cost saving of $300 per patient over 5 years. The results indicate that, for the most part, Canadian oncologists have been influenced by the available literature concerning follow-up practices and are ordering fewer routine tests. Further cost savings to the Canadian health care system could be achieved with the adoption of even less interventionist follow-up programs.
