Abstract
We investigated results for thoracic T3-T4 esophageal squamous cell carcinoma in two strategies. The protocol group (46 patients) consisted of neoadjuvant chemoradiotherapy (44 Gy, CDDP, 5-FU), followed by either definitive radiotherapy (total 70 Gy) for responders or surgery for non-responders. The surgery group (26 patients) underwent esophagectomy with regional lymph node dissection. Nineteen of them received postoperative radiotherapy. Surgical candidates in both groups received intraoperative radiotherapy for abdominal lymphatics since 1991. In the protocol group, 23 patients underwent radical surgery after neoadjuvant chemoradiotherapy and the remaining 23 underwent definitive radiotherapy. The rates of recurrence were 64% in the protocol group, and 62% in the surgery group. Overall 3- and 5-year survival rates were 48% and 31% in the protocol group compared to those of 30% and 30% in the surgery group. The rate of the was 39% in the protocol group. There was no mortality in either group. Our protocol had at least comparable prognostic values with historical conventional surgery, and was excellent in having feasibility for organ preservation.
