Carcinomas of the esophagus with synchronous or metachronous primary carcinoma in other organs.

Twenty-eight patients with esophageal carcinoma and one or more separate primary carcinomas in other organs were treated from 1960 to 1980, representing 8.3 per cent of the 339 cases of esophageal carcinoma observed during this period. The most frequent sites of the additional tumors were the oral cavity and pharynx (11 patients) and the stomach (12 patients). Awareness of the frequent combination of esophageal carcinoma with other primary neoplasms in the sites mentioned may lead to the detection of small curable malignant tumors.
