Clinical surveillance testing after lung cancer operations.
BACKGROUND
Although routine clinical surveillance testing after lung cancer operation has important clinical implications for patients and financial implications for society, the ideal surveillance strategy is unknown.


METHODS
We surveyed The Society of Thoracic Surgeons membership by questionnaire to characterize the current practice of follow-up among experts in lung cancer treatment. There were 2,009 responses (54% return) from the 3,700 members; 768 of those responding both operate on and provide long-term follow-up for lung cancer patients. These responses form the basis of this study.


RESULTS
The follow-up methods most frequently used during a 5-year follow-up include clinic visit, chest roentgenography, complete blood cell count, liver function testing, and chest computed tomography. Sputum cytology, head computed tomography, bone scanning, chest magnetic resonance imaging, and bronchoscopy are used infrequently. Although there is wide variation in the frequency of use of these ten methods, there is significant (p < 0.05) decrease in the frequency of testing over time for all tests except sputum cytology and chest magnetic resonance imaging. The survey also requested information regarding motivation behind routine clinical surveillance testing. Although the presumed rationale for such follow-up includes probable clinical benefit for the patient, fewer than half of respondents believe that such surveillance testing would yield a survival benefit for either stage I (44% of respondents) or advanced-stage patients (17% of respondents) after lung cancer resection. Only 1 of 4 respondents believe that the current literature documents any survival benefit. Other reasons for follow-up include maintenance of rapport with colleagues or patients and medicolegal liability concerns.


CONCLUSIONS
This survey provides direct evidence regarding current surveillance practice among thoracic surgeons. There appears to be marked variation among members of The Society of Thoracic Surgeons in frequency of and rationale for routine clinical surveillance testing.
