Abstract
This report documents the experience of the authors with two patients who had received thoracic radiation for disseminated teratocarcinomas of the testis, survived their malignancies, and subsequently developed squamous cell carcinomas of the esophagus. To the authors' knowledge, only 11 other cases of esophageal malignancies arising in patients who had received previous mediastinal irradiation have been reported in the world literature. With increasingly successful mediastinal radiation for malignant disease resulting in prolonged patient survival, an increasing number of such patients with subsequent esophageal malignancies can be anticipated. Close follow-up of patients receiving radiation therapy to periesophageal tissues is recommended, and prompt evaluation of any symptoms of esophageal dysfunction is indicated.
