How tumor stage affects surgeons' surveillance strategies after lung cancer surgery.

Abstract

The factors that influence decision making among surgeons are not well understood. We evaluated how tumor stage in patients subjected to potentially curative surgery for lung cancer affects the self-reported follow-up strategies employed by practicing surgeons. Hypothetical patient profiles and a detailed questionnaire based on these profiles were mailed to the 3,700 members of the Society of Thoracic Surgeons. The effect of TNM stage on the surveillance strategies chosen by the respondents was analyzed. All of the ten most commonly employed surveillance modalities were ordered significantly more frequently with increasing TNM stage, although the differences are small. Only 23% of respondents modified their strategies according to the patient's TNM stage. This effect persisted through 5 years of follow-up. We conclude that most surgeons performing surveillance after potentially curative surgery for otherwise healthy patients with lung cancer use the same follow-up strategy irrespective of TNM stage. These data should help in the design of prospective trials of this topic.
