Squamous cell carcinoma represents more than 90% of esophageal cancers; its prognosis is still extremely severe. A treatment consisting in the combined use of preoperative chemotherapy and radiotherapy is now in course of experimentation at Istituto Nazionale Tumori, Milan. Over a period of 28 months (July 1985 to October 1987), 21 patients with 22 lesions (stage III) underwent a double contrast study of the esophagus, both before and after therapy. The radiological evaluation of the lesions after treatment was compared with the pathological diagnosis. Radiological diagnosis has been confirmed in 86.3% of cases (19/22 lesions) as far as mucosal detailing was concerned. On the contrary, radiological evaluation has proven unreliable as far as submucosal layers were concerned. No radiological false positives have been observed.
