title: Long-term survival of patients with carcinoma of the esophagus in Puerto Rico.
abstract: From 1950 to 1971 a total of 4,342 cases of carcinoma of the esophagus were reported to the Central Cancer Registry of the Puerto Rico Health Department. Fifty-eight patients with histologic proof of their diagnosis survived five or more years, for an absolute survival of 1.3 per cent. Neither location of the tumor or type of treatment made much difference in average survival. In fact, 20 of the 58 patients had metastasis or extension of the tumor to adjacent tissues at sometime in their clinical course.
