ObjectiveTo clarify the impact of the preoperative time intervals on short-term postoperative and pathological outcomes in esophageal cancer patients who underwent neoadjuvant chemoradiotherapy (nCRT) followed by esophagectomy.Summary Background DataThe impact of preoperative intervals on esophageal cancer patients who received multimodality treatment remains unknown.MethodsPatients(cT1-4aN0-3M0) treated with nCRT plus esophagectomy were included using the Dutch national DUCA-database. Multivariate logistic regression was used to determine the effect of different time intervals upon short-term postoperative and pathological outcomes: diagnosis-to-nCRT intervals (≤5, 5-8 and 8-12 wk), nCRT-to-surgery intervals (5-11, 11-17 and >17 wk) and total preoperative intervals (≤16, 16-25 and >25 wk).ResultsBetween 2010-2021, a total of 5052 patients were included. Compared to diagnosis-to-nCRT interval ≤5 weeks, the interval 8-12 weeks was associated with higher risk of overall complications (P=0.049). Compared to nCRT-to-surgery interval 5-11 weeks, the longer intervals (11-17 wk and >17 wk) were associated with higher risk of overall complications (P-value=0.016; P-value<0.001) and anastomotic leakage (P-value=0.004; P-value=0.030), but the interval >17 weeks was associated with lower risk of ypN+ (P-value=0.021). The longer total preoperative intervals were not associated with the risk of 30-day mortality and complications compared to the interval ≤16 weeks, but the longer total preoperative interval (>25 wk) was associated with higher ypT stage (P-value=0.010) and lower pCR rate (P-value=0.013).ConclusionIn patients with esophageal cancer undergoing nCRT and esophagectomy, prolonged preoperative time intervals may lead to higher morbidity and disease progression, and the causal relationship requires further confirmation.Copyright © 2024 Wolters Kluwer Health, Inc.
