Surveillance for locally advanced esophageal and gastroesophageal junction (GEJ) cancers: Patterns of recurrence and methods of detection.

32Background: Trimodality treatment with neoadjuvant chemoradiation (CRT) followed by surgery is a standard treatment for esophageal/GEJ (E/GJ) cancers. Following esophagectomy, there is no strong consensus about optimal surveillance and routine imaging. At our institution, patients have surveillance CT scans every 4-6 months for the first 2 years post-surgery and every 6-12 months for the next 3 years. Methods: An IRB-approved chart review was performed identifying patients who underwent surgical resection for locally advanced E/GJ cancer between January 2011 and December 2015 at the University of Rochester. Study objectives were to describe timing of and methods used to detect recurrence as well as their impact on patient outcomes. Recurrence-free (RFS) and overall survival (OS) were graphed via the Kaplan-Meier method. Results: 138 patients underwent surgical resection for E/GJ cancer during the study period: 107 (77.5%) were male, median age was 64, and 116 patients (84.1%) had adenocarcinoma. 111 pat...
