title: Radiation therapy of esophageal carcinoma: correlation of clinical and radiographic findings.
abstract: Seventeen patients with esophageal carcinoma treated by radiation therapy (RT) at our hospital between 1981 and 1984 had initial diagnostic esophagrams and 1 or more repeat esophagrams after completing RT. Total regression of the tumor was observed radiographically in 10 patients (59%) with a normal esophagus (24%) or benign-appearing residual stricture (35%) at the site of the previous lesion. Partial regression was observed in 4 patients, and progression of the tumor in 3. No correlation was found between the size, stage, or morphology of the lesion and its response to therapy. Although local recurrences were relatively uncommon, patient survival was often limited by the development of distant metastases. Fourteen of 15 patients with clinical follow-up initially had significant relief from dysphagia as the tumor regressed. However, 9 of those patients had recurrent or increased dysphagia over a subsequent 3-9-month period. Exacerbation of symptoms did not necessarily indicate recurrent carcinoma; it also resulted from benign radiation strictures, opportunistic esophagitis, or other complications of RT detected on esophagography.
