摘要：

Background. We estimated the survival of patients with advanced carcinoma of the esophagus in Japan who achieved complete response (CR) with chemotherapy and/or radiation therapy. Methods. A questionnaire was designed for patients with cancer of the esophagus with pretreatment stage II-IV (excluding organ metastasis [M1]), who were treated with chemotherapy and/or radiation therapy and achieved either a clinical CR continuing for more than 1 year, or a pathological CR in surgical specimens. All patients were treated between January 1, 1990, and December 31, 1997, in Japan. Results. Of the 169 eligible patients for whom adequate data were available, 106 patients with continuing clinical CR were defined as group A and 63 with pathological CR as group B. The overall survival rates at 5 years were 62.4% in group A and 64.8% in group B. In each of groups A and B, there was no significant difference in overall survival among subgroups of patients classified by initial pretreatment clinical stage. In group A, the survival rate of patients with concurrent chemotherapy and radiation therapy was significantly better than the rates for patients with chemotherapy alone or radiotherapy alone. In group A, the frequency of first failure at the local site of esophageal carcinoma was 7.7%. Of the 12 patients in group B (19%) who died less than 1 year postoperatively, 6 died of postoperative complications. Conclusion. The effect of CR to chemotherapy and/or radiation therapy for carcinoma of the esophagus on survival was marked. In patients with esophageal carcinoma who achieve CR, the prognosis may be independent of the initial pretreatment stage. Local failure in group A patients remains a problem, however.
