Résumé
Surgery for gastric cancer should be performed as soon as possible after diagnosis. However, sometimes the waiting time for surgery tends to be longer. The relation between the waiting time for surgery and survival in patients with gastric cancer remains to be fully investigated. This retrospective, single-center cohort study evaluated patients with gastric cancer who underwent curative surgery from 2006 through 2012 at Kanagawa Cancer Center in Japan. Patients who received neoadjuvant chemotherapy were excluded. The waiting time for surgery was defined as the time between the first visit and surgery. We investigated whether the waiting time for surgery has a linear negative impact on outcomes by using a Cox regression model with clinical prognostic factors. In total, 801 patients were eligible. The median waiting time was 45 days (range 10-269 days). The restricted cubic spline regression curve showed that the adjusted time-specific hazard ratios of waiting times did not indicate a linear negative trend on survival between 20 and 100 days (p = 0.759). In the Cox model with a quartile of waiting times, waiting times in the 32-44-day group, 43-62-day group, and ≥63 day groups were not associated with poorer overall survival as compared with the ≤31 day group (HR: 1.01, 95% CI 0.63-1.60, p = 0.984, HR: 1.17, 95% CI 0.70-1.94, p = 0.550, HR: 1.06, 95% CI 0.60-1.88, p = 0.831, respectively). There was no negative relation between the waiting time for surgery (within 100 days) and survival in patients with gastric cancer.

BACKGROUND
Surgery for gastric cancer should be performed as soon as possible after diagnosis. However, sometimes the waiting time for surgery tends to be longer. The relation between the waiting time for surgery and survival in patients with gastric cancer remains to be fully investigated.
METHODS
This retrospective, single-center cohort study evaluated patients with gastric cancer who underwent curative surgery from 2006 through 2012 at Kanagawa Cancer Center in Japan. Patients who received neoadjuvant chemotherapy were excluded. The waiting time for surgery was defined as the time between the first visit and surgery. We investigated whether the waiting time for surgery has a linear negative impact on outcomes by using a Cox regression model with clinical prognostic factors.
RESULTS
In total, 801 patients were eligible. The median waiting time was 45 days (range 10-269 days). The restricted cubic spline regression curve showed that the adjusted time-specific hazard ratios of waiting times did not indicate a linear negative trend on survival between 20 and 100 days (p = 0.759). In the Cox model with a quartile of waiting times, waiting times in the 32-44-day group, 43-62-day group, and ≥63 day groups were not associated with poorer overall survival as compared with the ≤31 day group (HR: 1.01, 95% CI 0.63-1.60, p = 0.984, HR: 1.17, 95% CI 0.70-1.94, p = 0.550, HR: 1.06, 95% CI 0.60-1.88, p = 0.831, respectively).
CONCLUSIONS
There was no negative relation between the waiting time for surgery (within 100 days) and survival in patients with gastric cancer.
