Metastatic esophageal tumors from distant primary lesions: report of three esophagectomies and study of 1835 autopsy cases

Abstract

Three cases of esophagectomy for secondary esophageal carcinoma metastasized from the ovary, breast and lung are reported. Long-term survival, 14 and 4 years, after esophagectomy was achieved in two patients. The intervals between surgery for primary cancer and dysphagia onset in these two patients were 16 and 7 years, respectively. An aggressive surgical approach appears to be the therapeutic procedure of choice for metastatic esophageal carcinoma when the primary tumor growth rate is suspected to be slow. Autopsy data on 1835 cases revealed 112 (6.1%) had metastasis to the esophagus. The lung was the most common primary tumor-bearing organ and the diffusely infiltrative type was the most common esophageal tumor observed macroscopically which corresponded to the findings in our three patients. When an esophageal stricture with normal mucosa is encountered, a metastatic tumor must be taken into consideration.
