Squamous carcinoma of the distal esophagus: a survival study. A survival study for squamous carcinomas of the distal esophagus treated by the Southern California Permanente Medical Group in the interval of 1954 to 1988 was undertaken. We found radiation therapy and surgery equally efficacious in terms of cure for patients without distant disease and performance status sufficient to tolerate treatment. We did not find survival benefit for patients treated with palliative surgery, and plan less invasive endoscopic means along with chemotherapy and radiation for palliation, reserving surgery for special circumstances.
