title: Resection surgery with neoadjuvant chemoradiotherapy improves outcomes of patients with T4 esophageal carcinoma.
abstract: The prognosis of patients with T4 esophageal carcinoma is poor, and thus an effective treatment needs to be established. The present study assessed the effect of chemoradiotherapy (CRT), postoperative morbidity and mortality, and survival time in 41 patients with T4 esophageal carcinoma. Of these, 24 received CRT followed by surgery (group A) and the remaining 17 were treated with CRT alone (group B). Postoperative complications in group A were compared with 251 patients (group C) who underwent surgery without CRT during the same period. Postoperative complications were more frequent in group A than group C (29.2% vs 8.4%, P < 0.05). The overall median survival of group A was statistically longer than that of group B (13.8 months and 3.3 months respectively, P < 0.001). Complete histologic response (grade 3) was documented in 4 group A patients (16.7%). The overall median survival of grade 3 patients was statistically longer than the rest of group A (38.9 months vs 8.8 months, P < 0.05). The data confirm that chemoradiotherapy creates tumor regression in some patients and allows resection surgery in T4 esophageal carcinoma. Moreover, surgery with CRT confers a survival advantage in T4 esophageal carcinoma.
