title: [Achalasia and esophageal cancer].
abstract: During the period included between January 1970 and December 1990, we studied 242 patients with manometric and radiological diagnosis of esophageal achalasia. Eight of these patients (3.3%) developed during the evolution of their disease an esophageal carcinoma. Eight cases showed histologic type of epidermoid carcinoma: 3 differentiated, 3 semi-differentiated and 2 anaplastic. Therapy for achalasia was: one patient, Heller myotomy, 4 patients, dilatations with bougies in numerous opportunities, and the other two patients receive no treatment for achalasia. Two patients reported tracheobronchial fistulas as complication of carcinoma. Treatment received for carcinoma included: three patients, radiotherapy (4000 rads); one patient, chemotherapy; one patient, chemotherapy and radiotherapy, one resection surgery and two patients feeding gastrostomy. All of the eight patients died within the year of diagnosis of epidermoid carcinoma.
