      Background

      We recently investigated contemporary practice in post-resection lung cancer surveillance, between the Society of Thoracic Surgeons (STS) and the European Society of Thoracic Surgeons (ESTS) updating a published STS survey and showed a wide variance of practice.

      In order to understand better the role of socio-demographics on this divergence, we aim to compare these patterns to those of members of the Japanese Association for Chest Surgery(JACS) as well as surveillance attitudes across these regions.

      A survey identical to the one conducted in 1995 among STS members was administered via mail or electronically to members of the STS, ESTS and JACS requesting responses from those treating NSCLC. Goodness of fit tests were used to compare profiles of respondents and attitudes toward testing between groups. Multivariable logistic regression was performed to examine for predictors of guideline concordant surveillance with CT.

      A total of 2978 STS member (response rate 7.8%, n=234), 1450 ESTS members (response rate 8.4%, n=122) and 272 JACS (response rate 40,8%, n=111) members were surveyed. All three societies reported similar use of history and physical examination for asymptomatic patients (75%vs78%vs73%p=0.52). Rate of guideline-recommended surveillance CT was reported highest among ESTS respondents for stage I patients (22% ESTS, 3% STS and 6% JACS members, p<0.01). However, both JACS and ESTS respondents reported higher rates of use of non-guidelines-recommended tests compared to STS respondents which persisted on adjusted analyses. In particular, JACS and ESTS respondents reported significantly higher use of brain MRI (JACS AOR 13.85 [7.46-25.73] ESTS AOR 2.81 [1.59-4.99], p<0.01), Bone Scan (ESTS AOR 3.00 [1.68-5.36] JACS AOR 5.69 [3.21-10.08], p<0.01) and bronchoscopy for post-resection surveillance (JACS AOR 3.51 [1.99-6.20] ESTS AOR 3.25 [1.83-5.79], p<0.01) compared to STS respondents. Regarding attitudes towards surveillance, more JACS and ESTS members either “agree” or “strongly agree” that routine testing for NSCLC recurrence results in potentially curative treatment (ESTS:86%, STS:70%, JACS:90% p<0.01). Similarly, JACS and ESTS respondents believe that surveillance would identify a curable second primary NSCLC (ESTS:94%, STS:84%, JACS:100% p<0.01) and that current literature documents definitive survival benefits from routine follow-up testing (ESTS:57%, STS:30%, JACS:62% p<0.01).

      8eea62084ca7e541d918e823422bd82e Conclusion

      The Japanese attitude towards surveillance is similar to that of ESTS members potentially highlighting significant differences between European and Asian surgeons compared to STS members and may be the underpinnings of routine use of non-guideline concordant surveillance. These differences clearly highlight the need of better prospective studies and joint recommendations to standardize practice globally.
