Summary: | Timely surgical resection in patients with suspected or diagnosed pancreas adenocarcinoma is an essential part of care. We hypothesized that longer surgical wait time was associated with worse oncologic outcomes.
A retrospective cohort of patients (N = 144) with resectable pancreas adenocarcinoma was divided into four wait time groups (<4, 4–8, 8–12, and >12 weeks), defined from the time of diagnosis on cross-sectional imaging. Overall and recurrence-free survival were analyzed using the Kaplan–Meier method and Cox proportional hazards regression. A higher rate of conversion to palliative bypass in patients waiting over 4 weeks was observed and further analyzed using post-hoc multivariate regression.
On multivariable analysis, longer wait time was associated with improved overall (HR 0.49, 95% CI: 0.28–0.85) and recurrence-free survival (HR 0.29, 95% CI: 0.15–0.56) in >12 weeks compared to <4 weeks group. On post-hoc analysis, longer wait time over 8 weeks was positively associated with palliative bypass (OR 5.33, 95% CI: 1.32–27.88).
Wait time over 8 weeks was associated with a higher rate of palliative bypass. There was an improvement in overall and recurrence-free survival in patients who waited over 12 weeks, likely due to selection bias. |
