Chemoradiotherapy followed by surgery compared with surgery alone in squamous-cell cancer of the esophagus.

Background We conducted a multicenter, randomized trial to compare preoperative chemoradiotherapy followed by surgery with surgery alone in patients with stage I and II squamous-cell cancer of the esophagus. Methods The preoperative combined therapy consisted of two one-week courses; each involved radiotherapy, in a dose of 18.5 Gy delivered in five fractions of 3.7 Gy each, and 80 mg of cisplatin per square meter of body-surface area, administered 0 to 2 days before the first day of radiotherapy. The surgical plan included one-stage en bloc esophagectomy and proximal gastrectomy by the abdominal and right thoracic routes, to be performed immediately after randomization in the group assigned to surgery alone and two to four weeks after the completion of preoperative chemoradiotherapy in the group assigned to combined therapy. Results A total of 297 patients entered the study; 11 were found to be ineligible, and 4 were lost to follow-up. Of the remaining 282, 139 were assigned to surgery alone and 143 to c...
