How practice patterns in colon cancer patient follow-up are affected by surgeon age.

BACKGROUND

Strategies for the follow-up of colon cancer patients after potentially curative treatment are known to vary widely. The optimal regimen remains unknown. We investigated whether the date of completion of formal surgical training affects choice of surveillance strategy.

METHODS

The 1070 members of the Society of Surgical Oncology (SSO) and the 1663 members of the American Society of Colon and Rectal Surgeons (ASCRS) were surveyed using a detailed questionnaire to measure how these surgical experts deal with colon cancer follow-up. Subjects were asked how they use nine specific follow-up modalities during years 1-5 following primary treatment for patients with colon cancer (TNM Stages I-III). Repeated-measures analysis of variance was used to compare practice patterns by TNM stage and year post-surgery, as well as by the year in which the surgeon's formal surgery training was completed.

RESULTS

Evaluable responses were received from 349 SSO members (33%) and 646 ASCRS members (39%). Few significant differences in follow-up practices were noted by training period, but follow-up for most of the nine modalities was highly correlated with TNM stage and year post-surgery, as expected.

CONCLUSIONS

This analysis indicates that the post-treatment surveillance practice patterns of surgeons caring for patients with colon cancer do not vary substantially with practitioner age. The data provide credible evidence that postgraduate education is effective in homogenizing practitioner behaviour.
