ABSTRACT
BACKGROUND:
The interval between preoperative chemoradiotherapy and surgery reportedly affects perioperative outcomes and survival; however, the optimal interval in esophageal cancer patients remains uncertain.OBJECTIVE:
Our aim was to determine whether a prolonged interval between preoperative neoadjuvant chemoradiotherapy (NACRT) and esophagectomy affects the outcomes of esophageal cancer patients.METHODS:
A total of 131 patients with esophageal cancer received curative surgery following NACRT at Akita University Hospital between 2009 and 2017. We divided these patients into two groups based on the median interval from NACRT to esophagectomy, and compared the rates of pathological complete response (pCR), surgical outcomes, and survival.RESULTS:
The median interval from NACRT to esophagectomy was 39 days (range 21-95). Of the 131 patients, 70 (53%) received esophagectomy after 39 days or more from completion of NACRT. There were no significant differences in the clinicopathological features, including pCR rates, between the two groups. Prolongation of the interval from NACRT to esophagectomy was significantly associated with an increased rate of anastomotic leakage and recurrent laryngeal nerve palsy (p = 0.0225 and p = 0.0022, respectively); however, no association with overall survival was detected.CONCLUSIONS:
A prolonged interval between NACRT and esophagectomy had no impact on pCR rates or survival. However, delaying esophagectomy may increase the likelihood of surgical complications such as anastomotic leakage and recurrent laryngeal nerve palsy.
