Cancer of the esophagus is a more prevalent disease than is commonly
thought. In the male it usually develops during the fourth and fifth
decades of life. There is in some cases the history of years of more
or less habitual consumption of strong alcoholic liquors. In the
female the condition often occurs at an earlier age than in the male,
and tends to run a more protracted course, preceeded in some cases by
years of precancerous dysphagia.
Squamous-celled epithelioma is the most frequent type of neoplasm. In
the lower third of the esophagus, cylindric cell carcinoma may be
found associated with a like lesion in the stomach. Sarcoma of the
esophagus is relatively rare (Bibliography 1, p. 449).
The sites of the lesion are those of physiologic narrowing of the
esophagus. The middle third is most frequently involved; and the lower
third, near the cardia, comes next in frequency. Cancer of the lower
third of the esophagus preponderates in men, while cancer of the upper
orifice is, curiously, more prevalent in women. The lesion is usually
single, but multiple lesions, resulting from implantation metastases
have been observed (Bibliography 1, p. 391). Bronchoesophageal fistula
from extension is not uncommon.
